Abstract :
Medications have to be both safe and effective. They can be potentially dangerous if taken in incorrect doses. Determining the correct medication doses requires understanding how the drug enters the body, how it is absorbed and how it is eliminated from the body and by what rates. It also requires knowledge of the factors affecting the rates of absorption and excretion. Without such knowledge, a patient is subjected to serious dangers. Our aim is to find a mathematical model to translate real-life drug intake processes into manageable mathematical expressions to give us an insight for determining drug dosages. A drug model was designed to express the processes of absorption and excretion of medications into and out of the blood. By solving these differential equations, we can reach a drug model representing drug levels in the GI tract and blood. Consequently, drug dosages can be determined in order to be both safe and effective.

Abstract :
Decomposing complete graph into subgraphs has wide application in the computer science. Numerous studies span on computation time. Thus, this paper aims to formulate a novel picturing method called Half Butterfly Method (HBM) to resolve the aforementioned problem. Several numerical examples will be provided towards developing HBM. The concept of Wing Strategy is proposed to create directions from one vertex to another vertex. Then, these directions are used to map distinct vertices. Furthermore, each structure of Hamiltonian circuits will be analyzed to determine isomorphism classes. It is shown that adjacency matrix can be used as a tool to classify up to isomorphism classes. Finally, the findings will be employed to list n! permutations.

Abstract :
In this paper, we explore theoretically the flow instabilities occur in thin liquid films of a perturbation flow using in Euler equation in Cartesian coordinate system. We derived the shallow water equations describing the motion of thin liquid film on the rotating cylinder surface. The governing equations have been constructed by using the usual multi-scale asymptotic expansion methods. The hodograph method is used to investigate the behavior of solutions of the liquid layer motion on the outer cylinder surface. It is found that, when the liquid layer located on the outer surface of the cylinder, the behaviors of solutions are periodic perturbations. The modelling results showed that the initial perturbations can develop in the unstable media. The diagrams are drawn to illustrate the physical properties of the exact solutions, and indicate their stability and bifurcation by using various techniques.

Abstract :
Illumination factors such as shading, shadow, and specular highlight observed from object surfaces can affect the appearance and analysis of the color images. Current invariant methods suffer from computation cost and the quality of the resulting image representation. This paper proposes an invariant representation for color images based on Hilbert Huang Transform (HHT) using Empirical Mode Decomposition (EMD); data driven based technique. The sifting method for EMD extracts the intrinsic functions (IFs) from the original images and hence generates the corresponding timeseries, and then uses Hilbert transform to provide the time-frequency-energy image representation of all selected IFs. Experimental results, show that the invariant formulas for color images based on HHT are invariant to highlight; shadow; surface geometry, and illumination intensity. The overall performance of the proposed representation is examined in experiments using real-world objects including metals and dielectrics in detail.

Abstract :
In this paper a new approach for data classification is presented based on Support Vector Machine (SVM) incorporating with Backtracking Search Algorithm (BSA). Support Vector Machine has achieved a great performance in many classification problems. SVM has several parameters, which have significant effect of the classifier performance. Different problems may require different parameter values. If parameters doesn’t take suitable values, results may turn out to be unsatisfactory. Therefore, a Backtracking Search Algorithm (BSA) approach is proposed to obtain the best parameters values to obtain better classification performance. To evaluate the performance of the proposed approach, datasets from UCI repository are used. The corresponding results were compared to several published approaches. The comparisons show that the proposed approach improved the classification accuracy rate in most datasets.

Abstract :
The Semantic Web is an extension of the current
web in which well-defined meaning is added to web content in order to make it machine readable. The term "search engine” is traditionally used to refer to crawler based search engines, manually maintained directories, and hybrid search engines. However, current search engines do not fully satisfy the users needs especially in terms of accuracy and specificity of the results. This paper proposes an approach to build a search agent system on top of the Semantic Web. In this work, an organization related ontology is used as well as annotated resources based on that ontology. The presented system consists of four main parts: the Ontology Parser, the Crawler, the Search Agent, and the Data Repository. Two kinds of search are implemented: classical and advanced. While classical is based on matching keywords to concepts and advanced search allows a user to choose the concept that s/he want to search for together with some attributes for this concept. A review on search engine techniques is also presented. The search agent was designed, built, and tested.

Abstract :
Fractional order derivative in mathematics is a natural extension of integer order derivatives. In order to deal with fractional order derivatives, many definitions are introduced, such as Riemann-Liouville, Grünwald-Letnikov, and Caputo, definitions. On the other hand, there are many applications of the fractional derivatives in different fields, including biology, chemistry, physics, geology, mechanical engineering, electrical engineering, control theory, astrophysics and social sciences.
In this talk, an overview will be given to some types of fractional Order differential equations for real life models such as the fractional cable equation and the fractional SIRC model and influenza A. Consequently, considerable attention has been given to the efficient numerical solutions of such models, because it is difficult to find the exact solutions for it. Special attentions is given to use the parallel weighted average finite difference method on a distributed system using message passing interface (MPI). The resultant large system of equations is studied using precondition conjugate gradient (PCG), with the implementation of cluster computing on it. The proposed approach fulfills the suitability for the implementation on Linux PC cluster through the minimization of inter-process communication.

Abstract :
The activation energy of crystallization for Ge15Se60Sb25 glass was investigated under non isothermal condition using a Differential scanning calorimeter (DSC) technique at various heating rates. The activation energy was determined by analyzing the data using Matusita et al.method. The variation of activation energy, Eα with the degree of crystallization ,α and hence with temperature was analyzed by iso-conversional methods, i.e. Kissinger-Akahira-Sunose (KAS) and Friedman (FR) methods. The results indicate that the activation energy of crystallization is not constant throughout the crystallization process but varies with the degree of crystallization and temperature. This variation indicates that the transformation from amorphous to crystalline phase is a complex process involving different mechanisms of nucleation and growth. The temperature dependence of activation energy of crystallization is explained in the light of the nucleation theory of Turnbull and Fisher. The Maleks kinetic procedure associated with non-linear regression approach was used to determine the kinetic model function. From the kinetic analysis of the non-isothermal crystallization of this composition, it was concluded that the empirical two-parameter Sestak-Berggren kinetic model was found to be the most adequate one to describe the crystallization kinetics .

Abstract :
The optical constants of as-prepared and thermally annealed Ge10Sb30Se60thin films were determined. Effect of heat treatment on the structure and optical properties of Ge10Sb30Se60 thin films in the range between the glass transition and crystallization temperature have been investigated. The glass transition and crystallization temperature of the synthesized sample was measured by non- isothermal DSC measurements. The microstructure and optical properties of these films were characterized by UV-VIS spectrum, scanning electron microscope (SEM) and X-ray diffraction (XRD). The optical band gap for as-prepared and annealed films have been calculated using Taucs low from the optical transmission and reflection spectra. The results indicate that the optical band gap Eopt increases when the annealing temperature (Ta) is lower than the glass transition temperature (Tg), while decreases with further increase of Ta. The XRD studies show that the as-prepared film is amorphous in nature, but the crystalline improved with increasing the annealing temperature. Furthermore the particle size and crystalline increases while the dislocation and strains decreases with increasing the annealing temperature. Thermal annealing was found to be accompanied by structural effects, which in turn, lead to change in the optical constants. The obtained results were explained in terms of the Mott and Davis model for amorphous materials and amorphous to crystalline structure transformations.

Some attempts are proposed for enhancement of infrared images using this model, since infrared images have several many applications, it is expected that CLAHE would be better in their enhancement than histogram equalization (HE). The simulation results show the superiority of CLAHE to HE in the enhancement of IR images from both the visual quality and Peak-to-peak signal-to-noise ratio (PSNR) points of view. So, applying this proposed method reinforces visual details in IR images enhancement.

Abstract :
This paper presents a shifted fractional-order Jacobi orthogonal function (SFJF) based on the definition of the classical Jacobi polynomial. A new fractional integral operational matrix of the SFJF is presented and derived. We propose the spectral tau method, in conjunction with the operational matrices of Riemann-Liouville fractional integral for SFJF and derivative for Jacobi polynomial, to solve a class of time-fractional partial differential equations (T-FPDEs) with variable coefficients. In this algorithm, the approximate solution is expanded by means of both SFJFs, for temporal discretization, and Jacobi polynomials for spatial discretization. The proposed tau scheme, both in temporal and spatial discretizations, is successfully reduced such problem into a system of algebraic equations which is far easier to be solved. Numerical results are provided to demonstrate the high accuracy and superiority of the proposed algorithm over the existing ones.

First, the system generates a binary mask that specifies the location of the eyeglasses in the input image. Next, the unwanted pixels from the image are completed using patch-based synthesis. Finally, the user chooses a new eyeglasses from a database of eyeglasses images to see his\her frontal image with the selected eyeglasses. One of useful application of the proposed system is an online eyeglasses shop, where the user can replace his\her eyeglasses with another one from the store and see his\her picture with the new one before buying it. Experimental results show that the proposed system effectively replaces eyeglasses from frontal face image of the user.

Abstract :
When a first-order differential equation is not separable, it is usually difficult to be solved by basic methods. Nevertheless, if Lie symmetry method is applied, new coordinates in which the differential equation is separable can be found, and the solution is straightforward in the new coordinates. Lie symmetry method involves finding symbols of the infinitesimal transformation followed by applying the method of characteristics to find the new coordinates. We attempted to apply lie symmetry method to solve a particular form of differential equations that would be complicated to be solved by basic methods.

Abstract :
The last decade has witnessed a dramatic progress and interest in the micro- and nano-fabrication techniques of complex devices to enable various applications. In almost all cases, an accurate quantitative theoretical modelling of these devices has to be based on advanced computational techniques that solve the corresponding, numerically very large linear, nonlinear or coupled partial differential equations. Photonic crystal fibers (PCFs) have attracted the interest of many researchers in recent years due to their unusual optical properties. PCFs can be endlessly single mode over a wide wavelength range, and can be tailored to achieve nearly zero and flat dispersion over a wide range of wavelengths. Recently, some attention has been devoted to the possibility of infiltration of the air holes with different materials such as polymer, oil, or liquid crystal (LC). However, PCF structure infiltrated by a LC has unique and uncommon propagation and polarization properties. In almost all cases, an accurate quantitative theoretical modelling of these devices has to be based on advanced computational techniques that solve the corresponding, numerically very large linear, nonlinear or coupled partial differential equations. In this regard, the photonics group headed by Prof. Obayya has contributed in the development of a “comprehensive numerical package” for the accurate numerical modelling of electromagnetic wave propagation in a wide range of microwave and photonic waveguides, cavities and devices. In this talk, the different computational modelling techniques will be first introduced. In addition, novel designs of high birefringence LC PCF infiltrated by a nematic liquid crystal (NLC-PCF) are presented and analyzed. Moreover, due to their different uses in communication systems, the performance of novel designs of high tunable polarization rotator, directional coupler, polarization splitter, multiplexer-demultiplexer, filter, temperature sensors based on the NLC-PCF will be introduced. The simulation results are obtained using full vectorial finite difference method, full vectorial finite difference beam propagation method, and finite difference time domain method (FDTD) with nonuniform meshing capabilities and perfect matched layer boundary conditions.

Abstract :
Often cyber-security or threat incidents research use regional and global ranking and percentage share for reporting. However, such cross-country comparisons seldom take into accounts the fact that many countries are of different sizes. Data normalization based on country sizes is thus required but often neglected. Countries with bigger economy, larger population and more machines are expected to have their regional and proportional share of incidents. To model such incidents based on country sizes, we use proportional linear model to generate expected values based on different size indicators. These values then can be used as baselines for cross-country comparisons, thereby observed values of cyber-security or threat incidents can be normalized. This article shows the usefulness of such approach by employing size indicators of (a) domestic product (GDP) at purchasing power parity (PPP), (b) Internet population, (b) population and (c) the number of IPv4 addresses as baseline indicators to generate expectations. It also plots a few observations that have been reported by certain cyber-security companies such as FireEye and Trustwave on countries in regions such as EMEA (Europe, Middle-East and Africa), META (Middle-East, Turkey and Africa) and LAC (Latin America and the Caribbean). More so than the conventional reporting based on ranking and percentage share, the linear proportional model is shown to be effective in identifying countries who have much more or less than their respective regional share of cyber-security incidents. We conclude with a discussion on the usefulness and requirements of this systematic approach and the implications of such linear proportional model in reporting cyber-security or threat incidents and making public policies.

Since Rosetta is the first journey to land on the surface of a comet. It was one of the greatest achievements of science in 2014. This mission was organized by ESA (European Space Agency) in 1993. The launch from the Earth was in 2004 and the land on the comet 67P Churyumov-Gerasimenko was in 2014 . It has been orbiting for 10 years in the solar system to be in the right orbital. For this motion in the solar system to be calculated, we can use Keplers Laws of Planetary Motion which was developed by Newton who proved it mathematically by using calculus and deferential equations.

Abstract :
The unsteady flow in porous medium of an incompressible Casson nanofluid bounded by two stationery parallel horizontal porous plates is studied. The heat and mass transfer are taken into our consideration. A non-Darcy model that obeys the Forchheimer extension is assumed for the characteristics of the porous medium. A uniform and constant pressure gradient is applied in the axial direction whereas a uniform suction and injection are applied in the direction normal to the plates. The two plates are kept at constant and different temperatures and the viscous dissipation is not ignored in the energy equation. Moreover, the concentration of the nanoparticles at the lower plate level differs from that at the upper one, while, both are kept constants. The system of momentum, heat and mass equations are solved numerically by using the finite difference scheme under the appropriate initial and boundary conditions. The effects of the porosity of the medium, inertial damping, the uniform (suction/ injection) velocity, the non-Newtonian Casson parameter, Eckert number, Prandtl number, Lewis number, Brownian motion parameter and thermophoretic parameter on the velocity, temperature and nanoparticles concentration distributions are investigated.

Abstract :
The calculus studied today were independently invented by Newton and Leibniz. However, the question that made a controversy in the 17th century was: Who created the study of change, infinitesimal calculus, first, Newton or Leibniz? Some authors identified the dispute as being about profoundly different methods. Thinking of everything in terms of motion, Newton considered the variable x as a fluent and its velocity x as a fluxion in his form of calculus,the method of fluxions and fluents. On the other hand, Leibniz used a differential triangle to obtain the slope of a tangent line to a curve and could derive the power, product and chain rules. The methods of Newton and Leibniz made great contribution in mathematics as well as physics.

Abstract
Rough set theory [6] is a recent approach for reasoning about data. It has achieved a large amount of applications in various real-life fields.
The main idea of rough sets corresponds to the lower and upper set approximations. These two approximations are exactly the interior and the closure of the set with respect to a certain topology on a collection U of imprecise data acquired from any real-life field. The base of the topology is formed by equivalence
classes of an equivalence relation E defined on U using the available information
about data.
The theory of generalized topology [1] was studied by Csaszar. It is well known that generalized topology in the sense of Csaszar is a generalization of the topology on a set. On the other hand, many important collections of sets related with the topology on a set form a generalized topology.
The notion of Nano topology [4] was introduced by Lellis Thivagar, which was defined in terms of approximations and boundary region of a subset of an universe using an equivalence relation on it. The purpose of this paper is to introduce and study a new generalized topology in terms of rough set called Nano generalized topology

Key words and phrases: Rough sets, topological space, generalized topology, Nano
topology.

Abstract :
Automatic detection of human face is an indispensable stage toward the design of face animation, face recognition/verification, human-computer interaction (HCI) and surveillance systems which encounter actions in uncontrolled circumstances. Nevertheless, occlusion, one of the obstacles for face detection based systems, can prevent efficiency of the performance for these systems. In this paper, we propose an efficient face detection method under partial occlusion whereas codebooks are learned for the human faces that formalize the locative distribution and various appearances of facial features. The codebooks are constructed by clustering a training set of facial features parts through extracting the distinctive features of spatial locality and orientation selectivity of Gabor filters bank. The posterior probability of the facial features and its relative location with respect to the face center are stored. Furthermore, localization of the face center is performed using adopted codebooks based on generalized Hough transform in Hough image where maxima peaks are corresponding to the face location. We tested the proposed method that achieved propitious results on publicly databases which show high efficiency to the state of the art.
Keywords: Face detection, Occlusion, Codebooks, Gabor filter, Hough transform.

Abstract :
Antilock braking systems are fitted to many new cars with the aims of improving their ability to steer while braking heavily and of reducing stopping distances on some road surfaces. Antilock brake system has been designed to achieve maximum negative acceleration by preventing the wheels from locking. Research shows that the friction between road and tire is a nonlinear function of wheel slip. Therefore, maximum negative acceleration can be achieved by designing a suitable control system for wheel slip regulation at its optimum value. In this paper, mathematical model have been developed to predict these different surfaces and accordingly control the wheel slip to achieve maximum friction coefficient for different road surfaces. The surface prediction and control methods are based on a quarter car model to simulate high speed braking performance. The results show the performance of the controller developed in this paper is reduced the stopping distance of the brake system.

Abstract — Medications have to be both safe and effective. They can be potentially dangerous if taken in incorrect doses. Determining the correct medication doses requires understanding how the drug enters the body, how it is absorbed and how it is eliminated from the body and by what rates. It also requires knowledge of the factors affecting the rates of absorption and excretion. Without such knowledge, a patient is subjected to serious dangers. Our aim is to find a mathematical model to translate real-life drug intake processes into manageable mathematical expressions to give us an insight for determining drug dosages. A drug model was designed to express the processes of absorption and excretion of medications into and out of the blood. By solving these differential equations, we can reach a drug model representing drug levels in the GI tract and blood. Consequently, drug dosages can be determined in order to be both safe and effective.

Abstract :
In this paper, we focus on the existence of travelling waves solutions for Reaction-Diffusion equations coupled with shallow water equations. We use the reaction diffusion equations to model the chemical reaction and the diffusion of sulfuric acid, which was carried by a barg that capsized into the Rhine river in 2011. In most cases, travelling waves solutions of a second order partial differential equation Are study by splitting the second order partial differential equation to a couple of first order ordinary differential equations, which may lead to an autonomous system. We show the existence of travelling waves solutions by following the phase plane analysis methods and discuss our model in a term of an autonomous system. We develop a numerical scheme based on Finite volume and Finite difference method to discretize the Burgers equation and reaction diffusion equation respectively. In the implementation, we use matlab program To obtain our numerical results.

In this paper, the derivatives of a smooth function are approximated with weighted sums of the function values at a group of so-called nodes, which are some points at which the function values are known. Lagrange approximation theory is used to approximate the function as a polynomial of the known values of the function at these nodes, then the different derivatives of the function is deduced from this polynomial. This approach is then verified by computing the Gaussian and Mean Curvatures of a Monkey Saddle Surface as an example for any other required 3-D surface.

Fractal geometry has always been a fascinating field as it relates between beauty, nature and mathematical equations.
Fractals were discovered way before being modeled by mathematical equations and computations. Fractals most significant properties are self-similarity and non-integer dimension, meaning that fractals are self-similar to the original body but they dont occupy the known dimensions that our eyes are familiar with. Modeling fractals mathematically can be done in many ways. One of them is complex number fractals. Fractals are represented on a complex plane using iterated functions. The Julia set and the Mandelbrot set are of the most famous complex number fractals that can be modeled easily and produce incredible fascinating images.

Abstract :
Many Problems in our life can be formed by mathematics modelling to simplify its solutions. Most of the problems is formed in differential equation form. And the one interesting part of mathematics to be studied is problems in infinite dimensional spaces. `Global attractor is a basic concept and tool to study asymptotic behaviours of solutions of nonlinear evolution equations. A global attractor is an invariant compact set absorbing all of the bounded sets as time goes to infinity and by use of this method we can reduce problems for motions in infinite dimensional spaces to some finite dimensional ones.

Let V be a matric space. A one parameter family {T(t)} of maps T(t) ?V ?V,t?0, is called a C^0 semigroup (strongly continuous semigroups) if
T(0) is the identity map on V,
T(t+s)=T(t) ᄚ T(s) for all t,s?0,
The function
[0,?)ᅲV?(t,x)? T(t)x?V.
Is continuous at each point (t,x)?[0,?)ᅲV.

Let {T(t)} be a C^0 semigroup in a metric space V. A function L?V?R is said to be a Lyapunov function for {T(t)} if
L is continuous on V and bounded below,
For each v?V function (0,+?)?t?L (T(t)v)?R is nonincreasing,
For any v?V we have
L (T(t)v)=const. For all t?0 implies that T(t)v=v for all t?0.

In this paper we will discuss existence of global attractor in strongly continuous semigroups {T(t)} that has Lyapunov function of a metric space with additional assumption for strongly continuous semigroups {T(t)}.


Keywords : Global Attractor, strongly continuous semigroups, Lyapunov function.

Abstract :
In this Work we look at a new version of sorting algorithms based
on divide-and-conquer algorithms. The Dual-pivot Quicksort algo-
rithm, sorts an unsorted list of length n distinct elements. It is a
version of the Unique pivot Quicksort, and both are stochastic divide-
and-conquer algorithms, which widely studied. In the Dual-pivot
Quicksort, two uniformly random chosen pivots are used to do the
job. In this paper a comprehensive survey and empirical study of the
Dual-pivot Quicksort algorithm is provided. The survey discusses in
detail some different variations of Quicksort starting with the original
version developed by Hoare in 1961 and ending with some of the most
recent ones. The study compared each algorithm in terms of the num-
ber of comparisons performed and the running times.The main object
is to analyze the running time performance of Dual-pivot Quicksort.
The limiting distribution of the normalized number of comparisons re-
quired by the Dual-pivot Quicksort algorithm is studied. It is known
to be the unique fixed point of a certain distributional transformation
T with zero mean and finite variance.
Keywords and phrases: sorting algorithms, Quicksort, Dual-pivot Quick-

Association Rule mining is one of the most important fields in data mining and knowledge discovery. Rare association rule is one of the association rule mining challenges. It is difficult to mine rare association rules with a single minimum support based frequent pattern mining algorithms such as Apriori and FP-growth. In this paper we propose an efficient multiple support frequent pattern growth algorithm “MSFP-growth” that combines the enhancement FP-growth algorithm with multiple minimum support using max constrain. The algorithm is implemented, and it is compared to other algorithms predecessor .The results that appear in rule mining from the proposed algorithm are 100% interesting and show faster performance than other algorithms without scarifying the accuracy.

Abstract :
Automatic detection of human face is an indispensable stage toward the design of face animation, face recognition/verification, human-computer interaction (HCI) and surveillance systems which encounter actions in uncontrolled circumstances. Nevertheless, occlusion, one of the obstacles for face detection based systems, can prevent efficiency of the performance for these systems. In this paper, we propose an efficient face detection method under partial occlusion whereas codebooks are learned for the human faces that formalize the locative distribution and various appearances of facial features. The codebooks are constructed by clustering a training set of facial features parts through extracting the distinctive features of spatial locality and orientation selectivity of Gabor filters bank. The posterior probability of the facial features and its relative location with respect to the face center are stored. Furthermore, localization of the face center is performed using adopted codebooks based on generalized Hough transform in Hough image where maxima peaks are corresponding to the face location. We tested the proposed method that achieved propitious results on publicly databases which show high efficiency to the state of the art.

Keywords: Face detection, Occlusion, Codebooks, Gabor filter, Hough transform.

Abstract :
Recently the use of 3d scanning has greatly increased in industrial purposes,and in the field of scientific research, therefore, the needs of get the 3D points cloud of objects is extremely important.
In this paper, we present a relatively inexpensive 3D points cloud acquisition system consists of two webcams and LCD projector, based on stereo system technologies. Comparing to the traditional methods, the novelty of our method is in the nature of the projection pattern and the type of image processing associated to them. Our method uses a random squires pattern instead of using standard binary patterns made out of black and white stripes. This choice allows us to inferred corresponding points between two webcams images in easy and effective way. The proposed acquisition system was experimented by scanning different objects with different shapes and for different numbers of scanning points.
For better comparison, we apply two different projection patterns, we used random squares pattern, and uniform squares pattern. For evaluating the accuracy of 3D points cloud, a plane was fitted to the 3D points. By computing the distance from each 3D point to the plane, the RMS error between the 3D points and the plane fitting is calculated.
The experiential results show that, the random squares pattern is more accuracy and faster than the uniform squares pattern for getting 3D points cloud for scanning objects.
The software for our proposed acquisition system was devolved to generate 3D points cloud automatically and it is implemented with C++ and open software library OpenCV.

Abstract :
The main advantage of conventional disc brake is the high ability to dissipate the generated heat due to friction. And, its main disadvantage is that, it is not self-amplified brake. The new wedge disc brake is self-amplified disc brake in additional to its high ability to heat dissipation. Therefore, the main objective of this study is to carry out a mathematical model of conventional and new wedge brake to predict the brake dynamic behavior under different operation conditions. A theoretical model using MATLAB program is conducted to investigate the effect of the coefficient of friction and the shoe stiffness on the dynamic properties of both conventional and wedge disc brakes. It is found that the friction coefficient has a very significant effect on the dynamic properties of the braking process for conventional and new wedge brakes.

Abstract :
In this article, we first introduce a Singular Fractional Sturm-Liouville problems (SFSLPs) on unbounded domain.
The associated fractional differential operators in these problems are both Weyl and Caputo type. The properties of spectral data for fractional operators on unbounded domain have been investigated. Moreover, it has been shown that the eigenvalues of the singular problems are real-valued and the corresponding eigenfunctions are orthogonal. The analytical eigensolutions to SFSLP are obtained and defined as generalized Laguerre fractional-polynomials. The optimal approximation of such generalized Laguerre fractional-polynomials in suitably weighted Sobolev spaces involving fractional derivatives has been derived. The obtained results demonstrate that the error analysis beneficial of fractional spectral methods for fractional differential equations on unbounded domains. We construct
efficient generalized Laguerre fractional-polynomials-Petrov-Galerkin methods for a class of prototypical fractional initial value problems (FIVPs) and fractional boundary value problems (FBVPs). As a numerical example,
we examine space fractional advection-diffusion equation. Our theoretical results are confirmed by associated numerical results.

Abstract :
The Milne problem of radiative transfer in fluctuating stochastic medium is considered. The properties of the medium are assumed to have fluctuations described as a Gaussian field. The problem is defined and solved at …first in the deterministic case. The solution is found to depend on two correlated random variables, namely the optical space variable and the optical thickness of the medium. The joint Gaussian probability density function of these two random variables is defined and used to find the ensemble-averaged energy density. It is shown that the statistical nature of the medium leads to two different definitions of the linear extrapolation distance. These two definitions are identical in the deterministic case. Numerical results are given for the energy density and the linear extrapolation distance for different values of the scattering albedo and different values of the stochasticity parameter.

Abstract :
The fractional complex transform is proposed to convert the nonlinear evolution fractional order equations into integer order differential equations. In this article, He’s Exp-function method (EFM) is used to construct solitary and periodic solutions of the nonlinear evolution equation. The time fractional derivatives nonlinear Boussinesq equations is chosen to illustrate the effectiveness of this method. The EFM presents a wider applicability for handling nonlinear wave equations. Also, it is shown that the EFM, with the help of symbolic computation, provides a straightforward and powerful mathematical tool for solving nonlinear evolution equations.

Abstract :
In this paper we introduce a certain subclass $\mathbf{GK_{2}}$ of the class of generalized $MS$-algebras. A simple triple construction of principal generalized $K_{2}$-algebras which works with pairs of elements only is given. We also characterize isomorphisms of these algebras by means of triples. Finally we introduce a notion of
congruence pairs for the class of principal generalized $K_{2}$-algebras. Then, we show that every congruence relation $\theta$ on a principal generalized $K_{2}$-algebra $L$ can be uniquely determined by a congruence pair $(\theta_{1},\theta_{2})$.

Abstract :
Non-similarity solution is obtained to examine the combined effect of spatially stationary surface waves and the presence of fluid inertia on free convection along a heated vertical wavy surface pointing downwards in a nanofluid saturated porous medium. In this pioneering study, it is assumed that the medium contains gyrotactic microorganisms along with nanoparticles and the surface is subjected to concentration of nanoparticles and density of motile microorganisms. The influences of Brownian motion and thermophoresis are incorporated into the model for nanofluids. The boundary-layer regime is considered where the Darcy–Rayleigh number is very large. A suitable coordinate transformation was considered to reduce the governing boundary-layer equations into non-similar. A detailed parametric study (nanofluid and bioconvection parameters) is performed to access the influence of the various physical parameters on the reduced Nusselt, reduced Sherwood and reduced microorganisms density numbers. The results of the problem are presented in graphical forms and discussed.

Abstract :
Due to the good performance of current SAT (satisfiability) and Max-SAT (Maximum

In this paper we tackle the course timetabling problem of the department of mathematics, Cairo University by encoding it into Max-SAT. Generating timetables for the department by hand has proven to be cumbersome and the generated timetable almost always contains conflicts. We show how the constraints can be modeled as a Max-SAT instance.

Abstract :
Modeling and visualizing molecular surfaces is very important in bioinformatics. These surfaces play an essential role in better understanding of the chemical and physical properties of molecules.
In this article, the molecular skin surface is considered since it is a continuously smooth surface described as a piecewise-defined algebraic equation.
Starting from a finite set of weighted points, representing the atoms of a molecule, an algebra is described that generates an infinite family of spheres such that the envelope of the spheres is called the skin, and the subset of R3 bounded by the envelope is called the body of the set of weighted points.
We describe a discrete framework and present algorithms constructing the body and the skin. Then present a framework for constructing the skin as a collection of quadratic patches. A mixed complex which is an intermediate complex between the Delaunay triangulation and the Voronoi diagram of the weighted points is used to divide the skin into patches. We present two different algorithms for meshing the skin surfaces with guaranteed topology, applying the algorithms on some proteins to prove their efficiency.

The application of the computer algebra techniques to the enzymes kinetic allows the reduction of a complex enzymes kinetics system with an initial fast transient into a simpler system. The simplified system yields insights into the behavior of the enzymes kinetic reaction, and analytical approximations can be obtained to determine its kinetic parameters.

Therefore,the study of the theoretical model for the enzyme reaction system is of interest for the industrial application of the biocatalyst. Theoretical modelling of the enzyme kinetics and the reactors can be used to find optimal operation points and to increase our knowledge about the process. The model usually contains information on the particular biocatalytic reactions.

Abstract :
The increasing study of inequalities is a reflection of their use in every branch of mathematics. The development of the famous Hardy inequality (in both its discrete and continuous forms) during the period 1906-1928 has its own history. Contributions of mathematicians other than Hardy, such as Landau, Littlewood, Pólya, Schur, Riesz, Copson, Leindler, Bennett and others are importnat here. Most of these results are given for the discrete inequalities. In this talk I will describe some of these contributions and present the time scale versions of these inequalities on time scales which as special case contains the discrete and continuous inequalities and give a unification of their proofs. Some Open problems will be presented for interested readers.

Abstract :
Surface acoustic wave (SAW) are waves that travel along the surface of a material exhibiting elasticity. These types of waves have found diverse applications in consumer and highly professional electronic devices and systems. This was possible above all due to the fact that they can perform different functions in the frequency range from 10 MHz to several GHz. Electronic devices employing SAWs typically use interdigital transducers to convert acoustic waves to electrical signals and vice versa. The present paper attempts to review a simplified research work done modeling and simulation of SAW delay line with identical and uniform apodization transducers. The Impulse Response model is selected as a computational model, and PTC mathematics computer aided design software is employed as a modeling tool for the simulation of the SAW device. Also, modeling results of an IF SAW filter device functioning at a center frequency of 70 MHz studied and presented then compared with two commercial devices. The results obtained in this work provide an adequate basis for understanding the parameters effects and to aid in the optimization processes of delay lines and BPF based upon these effects.

Abstract :
We extend the notions of Jordan higher derivation and Jordan triple higher derivation to rings with involution by introducing the following notions: Let $\mathbb{N}_0$ be the set of all nonnegative integers and let $D=(d_i)_{i\in \mathbb{N}_0}$ be a family of additive mappings of a $\ast-$ring $R$ such that $d_0=id_R$, $D$ is called a \emph{Jordan higher $\ast-$derivation} (resp. a \emph{Jordan triple higher $\ast-$derivation}) of $R$ if $d_n(x^2)=\sum_{i+j=n}d_i(x)d_j(x^{{\ast}^i})$ (resp. $d_n(xyx)=\sum_{i+j+k=n}d_i(x)d_j(y^{{\ast}^i})d_k(x^{{\ast}^{i+j}})$) for all $x,y \in R$ and each $n\in \mathbb{N}_0$. It is shown that the notions of Jordan higher $\ast-$derivations and Jordan triple higher $\ast-$derivations on a 6-torsion free semiprime $\ast-$ring are coincident.

Accepted : 1/7/2015 6:23:00 AM    
Abstract :
Many algorithms have been proposed to provide privacy preserving in data mining. These protocols are based on two main approaches named as: the perturbation approach and the Cryptographic approach. The first one is based on perturbation of the valuable information while the second one uses cryptographic techniques. The perturbation approach is much more efficient with reduced accuracy while the cryptographic approach can provide solutions with perfect accuracy. However, the cryptographic approach is a much slower method and requires considerable computation and communication overhead. In this paper, a new scalable protocol is proposed which combines the advantages of the perturbation and distortion along with cryptographic approach to perform privacy preserving in distributed frequent itemset mining on horizontally distributed data. Both the privacy and performance characteristics of the proposed protocol are studied empirically.

Abstract
Multi-waves are generated through direct or indirect interactions of ba-sic traveling waves. These nonlinear interactions of waves are suggested via nonlinear combinations and bilinear transformations respectively. The method used here generalizes the unied method proposed very recently by the author. It is shown that interactions of basic waves which are measured experimentally in a uid could help in interpreting phenomena
complexity. Further, waves blow up locally (local instability) or they un-dergo an explosive instability may be inspected through indirect interac-tions. A mechanism for line-lumps formation is viewed as linear indirect interaction of soliton wave. Further the solutions show that lumps waves packet that are composed of light and dark lumps, which are dual (in a pattern similar to the Peregrine solitons) or they are not uniformly dis-tributed in space. Also, wave- lattices result in the the interaction of two solitary, periodic or of snoidal elliptic waves. Waves generated via three wave-like-patterns and solitary waves are also illustrated. A stabilization mechanism of spatial (temporal)explosive instability is suggested. By ac-counting for the drag forces through wave-wave interactions, it is found that these spatial- (or temporal) instabilities are quenched every where (or at any finite time-values).

Abstract :
Human robot interaction is an evolving area of research in the past few years, it deals with how humans can interact with, send data to, or receive data from robots. One of the major obstacle in the fields way is how the robot can obtain the depth information of the surrounding objects. Few years ago, Microsoft has released a depth sensor that compute the depth information using IR rays. Many researches are conducted to control robot using depth sensors (Microsoft Kinect, Asus Xition) [1][2][3][4]. Although depth sensors are considered to be low cost, it may be unavailable for many users. In this work we develop a zero-cost system for controlling robots (iRobot) with a web-cam and just a red color on your hands. Our system requires no extra devices or hardware or other complex technologies. The system depends on color and object detection, segmentation, morphological operations and some activity recognition basics. Results section demonstrates very good results compared to those provided by depth sensors.

Adding new parameters to expand families of distributions, to exhibit added flexibility

the most important expanded families is presented, with some comparisons. We detect
essential features of the family that best fits any data set. In view of these features, a
new method is proposed for constructing families that best fit any data. Two of such
families are suggested, which are more tractable than many other known families and
they possess very wide range of the indices of skewness and kurtosis. Moreover, each
of these families contains all the possible types of distribution functions (df’s). Finally,
a successful application to a life data set is presented.

Abstract :
Breast cancer is the top cancer in women both in the developed and the developing world. Most of breast cancer is diagnosed in very late stages. Therefore, early detection remains the cornerstone of breast cancer treatment to improve breast cancer control and survival. Developing computer aided diagnosis system (CAD) can help radiologists in their decision. In this paper, we proposed a CAD system to segment and classify the breast cancer lesions in ultrasound images. The system is using marker controlled watershed transformation technique to identify the region of interest (ROI). Then, wavelet transform is applied to extract a set of features, in addition to gray level co-occurrence matrix (GLCM) and statistical features. The classification step determines whether the ROI is normal or focal lesion. Finally, focal lesion is classified as benign or malignant. Support vector machine (SVM), K-nearest neighbour (KNN) and classification via regression are used to achieve the classification task. The proposed method is validated using 10 folds cross validation and the obtained results were encouraging.

Abstract :
This talk is concerned with the optimal control problem of switching systems. Behaviour of the system is described by the collection of delayed stochastic differential equations which initial conditions depend on its previous state.The constraints on the system is defined by the functional equality on the end of each interval.
Necessary condition of optimality in form of Maximum Principle is established. Afterwards, using Ekeland’s Variational Principle the necessary condition of optimality for optimal control problem with constraints is obtained.

Breast cancer is the top cancer in women both in the developed and the developing world. Unfortunately, most of breast cancer is diagnosed in very late stages.

Title : Identification of a One-Diode Model Parameters of PV Devices From Nameplate Information Using Particle Swarm and Least Square Methods

Abstract :
In this paper, a simple method is proposed and verified to estimate the parameters of a one-diode model of PV modules based on particle swarm optimization (PSO) and least square (LS) algorithms. The proposed method requires only the PV module nameplate ratings at three points on the I-V curve at Standard Test Conditions (STC): short circuit (0,ISC), open circuit (VOC,0) and maximum power (VMPP,IMPP). The proposed method is tested on three different types of PV modules (poly-crystalline, mono-crystalline and thin film) of different ratings. A comparison between actual experimental data curves and the predicted PV characteristics is carried out for different operating conditions. As the one-diode model parameters of PV modules are unknown to us, the PSO algorithm has been tested 100 times (each of 200 iterations) to determine the average value of the model parameters. The corresponding relative percentage error between measured and predicted PV electrical parameters did not exceed 8 % in the worst case, while the elapsed CPU time of the PSO algorithm was less than 7 sec. Thus, the results proved the validity and effectiveness of the method to identify with good accuracy the parameters of a PV module using only the limited datasheet information. According to this study on the three PV modules, it has been observed that the LS method can fail to find a solution without a proper selection of the initial values. The limitation of the LS method has been overcome by utilizing the final PSO solution as initial condition for the LS nonlinear curve fitting algorithm using the same three operating points from the PV nameplate. With the LS method (initialized by PSO results) accurate solution is also obtained. So, the proposed parameter estimation approach has been validated by two techniques PSO and LS. The main contribution of this approach is its suitability for rapid prototyping of PV systems with a high precision without the need to install an experimental test rig so that the developing time and cost are reduced.

Abstract :
Senovilla family for a subclass of Petrov type-D stationary axisymmetric differentially rotating perfect fluids is considered. A scheme is presented to construct from a solution an interior of a rotating compact body satisfying energy conditions, and with a boundary of vanishing pressure. The equatorial plane of the body is a surface layer due to a jump in the second fundamental form. However, unlike previous results, the body is free from curvature singularities.
