Domain walls play a central role in a subject of recent interest, the braneworld scenario. In particular, BPS domain walls are investigated in detail in D = 4, N = 1 SUSY theories. We should consider hypermultiplets to realize D = 4, N = 1 SUSY theory on the world-volume. In order to have a potential with discrete degenerate vacua, they must have gauge interaction, or nonlinearity of kinetic te...

Always, some individuals in images are more important/attractive than others in some events such as presentation, basketball game or speech. However, it is challenging to find important people among all individuals in images directly based on their spatial or appearance information due to the existence of diverse variations of pose, action, appearance of persons and various changes of occasions...

to control the nonlinear numerical instability, throughout the time evolution of the eulerian form of the nonlinear rotating shallow water equations, it is necessary to add numerical diffusion to the solution. it is clear that, this extra numerical diffusion degrades the accuracy of the numerical solution and should be kept as small as possible. in a conventional approach a hyper-diffusion is u...

In this paper I describe some results on the use of virtual processors technology for parallelize some SPMD computational programs. The tested technology is the INTEL Hyper Threading on real processors, and the programs are MATLAB scripts for floating points computation. The conclusions of the work concern on the utility and limits of the used approach. The main result is that using virtual pro...

1 Ethan Bolker is also Professor of Computer Science at the University of Massachusetts, Boston. Intel’s recently introduced Hyper-Threading Technology (HTT) makes a single physical processor appear as two logical processors. Operating systems and applications can schedule processes or threads on those logical processors. The performance impact of HTT varies, depending on the nature of the appl...

This  paper extends the notion of fuzzy $BCK$-subalgebras to fuzzy hyper $BCK$-subalgebras and defines an extended fuzzy $BCK$-subalgebras. This study  considers  a type of fuzzy hyper  $BCK$-ideals  in this  hyperstructure  and  describes   the  relationship  between hyper  $BCK$-ideals and  fuzzy hyper  $BCK$-ideals.  In fact, it tries to introduce   a  strongly  regular  relation  on hyper $...

Ubiquitous computing is making it possible to increase the sensory feedback from everyday spaces to attract attention to often-neglected tasks, make them safer and easier and potentially motivate new behavior. HyperReality describes distributed computing interfaces that weave existing environments with immersive sound and images to expand sensory feedback from everyday activities. This paper di...

A simple method is described, to prove some theorems for simple hyper K-algebras and to study positive implicative hyper K-ideals, weak (implicative ) hyper K-ideals in simple hyper K-algebras . Beside, some results on positive implicative and (weak) implicative simple hyper K-algebras are presented. Finally classification of simple hyper Kalgebras of order 4, which are satisfied in conditions ...

The Web, but also for example a large extra-net such as a digital library, has an intricate topology that makes navigation through resources a tricky task. The mere introduction of Semantic Web technologies won’t automatically solve this task, because the Semantic Web only promotes machine understandability of Web resources by explicitly providing a thick bunch of annotations, thus leaving thei...

Gray & Hervella gave a classification of almost Hermitian structures (g, I) into 16 classes. We systematically study the interaction between these classes when one has an almost hyper-Hermitian structure (g, I, J,K). In general dimension we find at most 167 different almost hyper-Hermitian structures. In particular, we obtain a number of relations that give hyperKäher or locally conformal hyper...
