  • Interests in face recognition area have been increasing due to diverse emerging applications. Face recognition algorithm from a two-dimensional source could be challenging in dealing with some circumstances such as face orientation, illuminance degree, face details such as with/without glasses and various expressions, like, smiling or crying. Hopfield Network capabilities have been used specially within the areas of recalling patterns, generalizations, familiarity recognitions and error corrections. Based on those abilities, a specific experimentation is conducted in this paper to apply the Redundant Parallel Hopfield Network on a face recognition problem. This new design has been experimentally confirmed and tested to be robust in any kind of practical situations.

  • A least-squares identification method is studied that estimates a finite number of coefficients in the series expansion of a transfer function, where the expansion is in terms of recently introduced generalized basis functions, We will expand and generalize the orthogonal functions as basis functions for dynamical system representations. To this end, use is made of balanced realizations as inner transfer functions. The orthogonal functions can be considered as generalizations of, for example, the pulse functions, Laguerre functions, and Kautz functions, and give rise to an alternative series expansion of rational transfer functions. We show that the Laplace transform of the expansion for some sets$\Psi_{\kappa}(Z)$ is equivalent to a series expansion . Techniques based on this result are presented for obtaining the coefficients $c_{n}$ as those of a series. One of their important properties is that, if chosen properly, they can substantially increase the speed of convergence of the series expansion. This leads to accurate approximate models with only a few coefficients to be estimated. The set of Kautz functions is discussed in detail and, using the power-series equivalence, the truncation error is obtained.

  • To many, recent allegations of earnings management at Enron, coupled with similar ones at many other corporations, are a strong indication of a serious decay in business ethics. Nevertheless, the field of Corporate Social Responsibility(CSR) has grown exponentially in the last decade. This study investigates the effects of CSR on earnings management. Different to precedent works which focus on Financial Performance, this study attempts to provide empirical evidence for relevance of CSR and Discretionary Accruals(DA). The study used variables in the sustainability report, and DA for its earning management too progress empirical analysis because it is believed that the measurement of accounting transparency is highly related to the CEO's opportunistic selection of the accounting. In terms of Sustainable management activities, Employee training time(ETT) is significantly and negatively associated with Discretionary accruals(DA). And also Industrial Accidents Ratio(IAR) is significantly and negatively associated with Discretionary accruals. Consequently, empirical results suggest that Discretionary accruals associated with the company's CSR activities, such as ETT, and IAR. In this study, there are limitation of generalizations and omitted variable problem.

  • The subject of fractional calculus (that is, the calculus of integrals and derivatives of any arbitrary real or complex order) has gained considerable popularity and importance during the past over four decades, due mainly to its demonstrated applications in numerous seemingly diverse and widespread fields of mathematical, physical, engineering and statistical sciences. Various operators of fractional-order derivatives as well as fractional-order integrals do indeed provide several potentially useful tools for solving differential and integral equations, and various other problems involving special functions of mathematical physics as well as their extensions and generalizations in one and more variables. The main object of this survey-cum-expository article is to present a brief elementary and introductory overview of the theory of the integral and derivative operators of fractional calculus and their applications especially in developing solutions of certain interesting families of ordinary and partial fractional "differintegral" equations. This general talk will be presented as simply as possible keeping the likelihood of non-specialist audience in mind.

  • The purpose of this study is to investigate and examine the role of specialized marketing capabilities (SMC) in mediating the relationship between customer sensing capability (CuSC) and competitor sensing capability (CoSC) with business performance (BP) at SMEs retail fashion in Indonesia. This study used 330 SMEs from ten regencies in Indonesia and examined the regression relationship between the four variables, SMC, CuSC, CoSC, and BP. Confirmatory factor analysis (CFA) was used to measure the validity and reliability of the construct used. For data analysis techniques, this study used structural equation modeling (SEM) with AMOS Version 22.0. This study found that SMC acts as a partial mediator in the relationship between CuSC and CoSC with SMC and BP. By examining the diverse literature on market sensing capability, marketing strategy, and BP, this study offers a unique analysis of market learning and its effects on SMC and BP in Retail Fashion SMEs in Indonesia. Furthermore, future research needs to broaden the findings and improve generalizations by conducting studies of SMEs in other industries, such as manufacturing, and services of small, medium and large scale. In addition, it needs to add some countries as research objects, not only Indonesia.

  • Motivated by several generalizations of the Pochhammer symbol and their associated families of hypergeometric functions and hypergeometric polynomials, by choosing to use a very generalized Pochhammer symbol, we aim to introduce certain extensions of the generalized Lauricella function F(n)A and the Humbert's confluent hypergeometric function Ψ(n) of n variables with, as their respective particular cases, the second Appell hypergeometric function F2 and the generalized Humbert's confluent hypergeometric functions Ψ2 and investigate their several properties including, for example, various integral representations, finite summation formulas with an s-fold sum and integral representations involving the Laguerre polynomials, the incomplete gamma functions, and the Bessel and modified Bessel functions. Also, pertinent links between the major identities discussed in this article and different (existing or novel) findings are revealed.

  • Let R be a commutative graded ring with nonzero identity and n a positive integer. Our principal aim in this paper is to introduce and study the notions of graded n-irreducible and strongly graded n-irreducible ideals which are generalizations of n-irreducible and strongly n-irreducible ideals to the context of graded rings, respectively. A proper graded ideal I of R is called graded n-irreducible (respectively, strongly graded n-irreducible) if for each graded ideals I1, . . . , In+1 of R, I = I1 ∩ · · · ∩ In+1 (respectively, I1 ∩ · · · ∩ In+1 ⊆ I ) implies that there are n of the Ii 's whose intersection is I (respectively, whose intersection is in I). In order to give a graded study to this notions, we give the graded version of several other results, some of them are well known. Finally, as a special result, we give an example of a graded n-irreducible ideal which is not an n-irreducible ideal and an example of a graded ideal which is graded n-irreducible, but not graded (n - 1)-irreducible.

  • Hwang's scandal give us opportunity to aware about the research ethics, but that can not be established firmly in researcher or the researcher communities. This study analyse the case of research misconduct in order to establish research ethics that was appeared in Assembly hearing process for the candidate of the minister of education(MOE) in July 9, 2014. Based on the analytic results, this study is proposed that provide the institutions to promote responsible conduct of research, implement the research ethics education to all researchers and improve the laboratory culture and evaluation system. This study has the limitations because a single case study. The study is expected to have interest in research ethics and to be up to empirical generalizations through quantitative research.

  • Objectives : The purpose of this study which adopted a qualitative method was to evaluate blood pressure management behaviors of pre- and stage 1 hypertension patients and to provide fundamental data for developing a strategy about proper oriental medical treatment through analyzing factors related to a moxibustion clinical trial. Methods : Semi-structured interviews that focused on personal experiences with hypertension and its management were conducted with 10 hypertensive patients. The interviews lasted for approximately 50 minutes. Results : Most participants recognized that the direct cause of high blood pressure was unhealthy behavior rather than inheritance. Thus, the hypertensive patient believed they could recover their blood pressure to a normal level through removing the direct cause of hypertension instead of taking drugs. The reasons for these statements were that the drugs for controlling hypertension are not natural and they may have side effects. On future management plan of patients, most of them will continue to keep moxibustion and healthy behavior in the well-controlled blood pressure group. However in the uncontrolled blood pressure group, there was an increasing tendency to begin medication. Conclusions : For developing a strategy for an individual approach to hypertension management, we need to develop a client-centered attitude and strategy. That is, we need to tailor our approach to individual cases to avoid generalizations and stereotyping when developing an adherence increasing strategy.

  • In this paper, we propose an algorithm on partitioning a network into several subsets where the cost of a net which connects nodes in k subsets is given as k(k-1)/2 indicating the typical pattern of complete graphs. This problem is one of generalizations for multiple-way partitioning proposed by Sanchis. $^{[5]}$ Its solution can be applied to resource allocation problem in distributed systems. The proposed algorithm expanded the algorithm of Fiduccia and Mattheyses$^{[3]}$ to handle the multiple-way partitioning simultaneously. It has time and space complexity linear to the size of the network. To evaluate the performance of the proposed algorithm, we implemented also a traditional cluster growth method which groups connected nodes for nets, and compared experimental results with those of the proposed algorithm. The proposed algorithm shows some enhancement made.
