We introduce a hierarchy of linear systems for showing that given subspace pure quantum states is entangled (i.e., contains no product states). This outperforms known methods already at the first level, and it complete in sense every shown to be so some finite level hierarchy. It straightforwardly generalizes case higher Schmidt rank, as well multipartite cases completely genuinely subspaces. T...

Based on behavioral studies, several relatively distinct perceptual and cognitive functions have been defined in cognitive psychology such as sensory memory, short-term memory, and selective attention. Here, we review evidence suggesting that some of these functions may be supported by shared underlying neuronal mechanisms. Specifically, we present, based on an integrative review of the literat...

Caches are traditionally organized as a rigid hierarchy, with multiple levels of progressively larger and slower memories. Hierarchy allows a simple, fixed design to benefit a wide range of applications, since working sets settle at the smallest (i.e., fastest and most energy-efficient) level they fit in. However, rigid hierarchies also add overheads, because each level adds latency and energy ...

We investigate automatic presentations of infinite words. Starting points of our study are the works of Rigo and Maes, and Carton and Thomas concerning the lexicographic presentation, respectively the decidability of the MSO theory of morphic words. Refining their techniques we observe that the lexicographic presentation of a (morphic) word is canonical in a certain sense. We then go on to gene...

In this paper, we propose a hierarchical framework for providing fault tolerance to the SIFT layer of a distributed system, and extending it to the applications executing in such an environment. The detection hierarchy is proposed in the context of Chameleon, a software environment for providing adaptive faulttolerance in a COTS environment to off-the-shelf software. A flexible mechanism for co...

Location awareness is a key feature of mobile information systems. Typically, location is determined by interpreting a set of measured positions. Various approaches for position determination do exist. They vary greatly in their precision, applicability, and energy requirements. As mobile devices are battery-driven, energy is one of the most limiting factors for the system’s uptime. Locations h...

Frequent pattern mining has become one of the most popular data mining approaches for the analysis of purchasing patterns. There are techniques such as Apriority and FP-Growth, which were typically restricted to a single concept level. We extend our research to study Multi level frequent patterns in multi-level environments. Mining Multi-level frequent pattern may lead to the discovery of minin...

citizen relationship management is a novel approach for public sector and governmental organization to improve their services and to achieve citizen satisfaction. the main purpose of this study is to identify and prioritize customer segmentation in governmental organizations. for the reason, based on reviewing the literature, four group of psychological, demographic, behavioral, and situation f...
