Dynamics, circuit design and fractional-order form of a modified rucklidge chaotic system
No full textRucklidge chaotic system is a nonlinear mechanical model of a double convection process. In this paper, we modify the dynamics of a Rucklidge chaotic system by adding a nonlinear term and derive a new chaotic system. The nonlinear dynamics of the proposed chaotic system is described through numerical simulations which include the stability analysis of equilibrium points, phase portraits, Lyapunov exponents, Kaplan-Yorke dimension, bifurcation diagram and a Poincare map. For specific values of the parameters, the proposed system displays periodic and chaotic behaviour. In addition, a new circuit implementation of the modified Rucklidge chaotic system is reported and examined in MultiSIM. A good qualitative agreement is shown between the simulations and the MultiSIM results. Furthermore, the fractional-order form of the modified Rucklidge chaotic system is numerically studied. By tuning the commensurate fractional order, the new chaotic system displays chaotic and periodic attractors, respectively

No full textA new model of barakah house financing among public in Malaysia was constructed based
on the Integration model. The aim of the study was conducted in order to investigate the
acceptance of public on this newly constructed model. A total of 300 respondents were
chosen in the field study in Malaysia. The questionnaires distributed consist of five
variables, where four were independent variables and one was dependent variable. By
using a SEM Amos, it is found that each independent variable has strong correlation with
the single variable. This can be concluded that the public has accepted this new
constructed model. This study suggested that this new plan is implemented by people who

The application of web 2.0 tools to determine Malay AFL-learners’ performances in receptive skills
No full textThe application of modern technologies in educational fields thrills with a sudden shift in using
of the internet from Web 1.0 to Web 2.0 in the early 21st century. In the time various
technological tools and social media sites evolved for social, entertainment and educational
purposes. The application of such technological tools in teaching and learning of a language is
termed computer-assisted language learning. This study aims to determine the performance of
Malay undergraduate learners of Arabic as a foreign language at UinSZA in reading, and
listening skills using the online tool "QuizCreator Online”. The sample of the study comprises
30 Malay Undergraduate students that are learning Arabic as a foreign language at UniSZA.
The data of the study are collected through test instrument designed and marked based on
TOAFL (AL-ARABIA) marking scheme deployed into “QuizCreator Online”. The results
indicated that only 7 participants scored pass points in reading skill test and 8 participants in
listening skill test. In reverse case, 23 participants failed reading skill test and 22 participants in
listening skills test. The results indicated the passing rate in reading skills test as 28.35 % and
29.21 % in listening skills test. This study recommends the use of web 2.0 tools such as Blogs,
Edmodo, Facebook and QuizCreator Online tools teaching and learning of Arabic language to
Maly AFL learners

No full textA secured openflow protocol using Elliptic Curves Cryptographic for software defined networks
No full textA Software-Defined Network (SDN) architecture was proposed to enhance the performance, flexibility and scalability of networks. However, SDN features such as centralized controlling, network programmability and virtualization present new security challenges to networks. This article will address security challenges related to SDN connection data transfer channels (i.e., control layer and infrastructure layer) and propose a novel connection data transfer channels architecture based on an OpenFlow protocol. Existing SDN OpenFlow protocols rely on higher layer secure mechanisms such as TLS (Transport Layer Security) / SSL (Secure Sockets Layer) sessions. It is concluded that the transfer of secured data using elliptical curve encryption provides a more efficient SDN network. The proposed architecture was implemented in a testbed and its security features were analyzed
Brand evangelism among university students: a study on antecedents
No full textThe role of the brand in higher education has been considered as very important.
The brand is possibly the most important connection a prospective student has with an
institution. The brand of a University carries with it a promise of a particular level of service
and student outcomes. In the case of education, the service is more than a simple set of tangible
features but is a complex bundle of benefits that satisfy customer’s needs. As universities
around the world are expanding their marketing campaign, prospective students undertake a
complex consumer decision making process when it comes to selecting a university to attend,
and branding becomes a means to simplify their selection process. In today’s highly connected
marketplace, contemporary organizations like higher education institutions are also paying
careful attention to a relatively smaller, but highly influential, group of consumers called brand
evangelists who embrace their brands intensely, actively disseminate brand related
experiences to others, attempt to recruit others to experience the brand, and dissuade others
from consuming rival brands. Hence this study attempt to study on the antecedents of brand
evangelism among university students in Malaysia. Specifically, this study examines the
relationship between customer orientation, competitor orientation, interfunctional
coordination, brand orientation and perceived quality, university reputation and emotional
environment with brand evangelism. A study focused on public and private Higher Education
Institutions (HEIs) in East Coast of Peninsular Malaysia. Samples of 593 university students
were collected via survey questionnaire. The study utilized Structural Equation Modeling
statistical technique to test the study hypotheses. Results shown that customer orientation,
brand orientation and perceived quality, university reputation and Emotional Environment
were positively effect on brand evangelism among students in university. Nevertheless,
customer orientation and interfunctional coordination were not significantly related to brand
evangelism
Derivative free Davidon-Fletcher-Powell (DFP) for solving symmetric systems of nonlinear equations
No full textResearch from the work of engineers, economist, modelling, industry, computing, and scientist are mostly nonlinear
equations in nature. Numerical solution to such systems is widely applied in those areas of mathematics. Over the
years, there has been significant theoretical study to develop methods for solving such systems, despite these efforts,
unfortunately the methods developed do have deficiency. In a contribution to solve systems of the form F (x) = 0, x is
an element of R-n, a derivative free method via the classical Davidon-Fletcher-Powell (DFP) update is presented. This
is achieved by simply approximating the inverse Hessian matrix with Q(k+1)(-1) to theta I-k. The modified method
satisfied the descent condition and possess local superlinear convergence properties. Interestingly, without
computing any derivative, the proposed method never fail to converge throughout the numerical experiments. The
output is based on number of iterations and CPU time, different initial starting points were used on a solve 40
benchmark test problems. With the aid of the squared norm merit function and derivative-free line search technique,
the approach yield a method of solving symmetric systems of nonlinear equations that is capable of significantly
reducing the CPU time and number of iteration, as compared to its counterparts. A comparison between the proposed
method and classical DFP update were made and found that the proposed methodis the top performer and
outperformed the existing method in almost all the cases. In terms of number of iterations, out of the 40 problems
solved, the proposed method solved 38 successfully, (95%) while classical DFP solved 2 problems (i.e. 05%). In terms
of CPU time, the proposed method solved 29 out of the 40 problems given, (i.e. 72.5%) successfully whereas classical
DFP solves 11 (27.5%). The method is valid in terms of derivation, reliable in terms of number of iterations and
accurate in terms of CPU time. Thus, suitable and achived the objective
