This paper presents a policy-based framework for managing access control in distributed heterogeneous systems. This framework is based on the PDP/PEP approach. The PDP (Policy Decision Point) is a network policy server responsible for supplying policy information for network devices and applications. The PEP (Policy Enforcement Point) is the policy client (usually, a component of the network de...

We present here measurements of plasma display panel PDP ignited by SrO and SrCaO cold cathodes with high yield of ion-induced secondary electron emission high i . SrOand SrCaO-cathode PDPs attain high luminous efficacy at low applied voltage, where the breakdown voltage is 30% lower than that of ordinary MgO-cathode PDP. Current and emission measurement clearly demonstrates that SrOand SrCaO-c...

Current differential based wide area protection (WAP) has recently been proposed as a technique to increase the reliability of protection systems. It increases system stability and can prevent large contingencies such as cascading outages and blackouts. This paper describes how power differential protection (PDP) can be used within a WAP and shows that the algorithm operates correctly for a...

Recent interest in PDP (parallel distributed processing) models is due in part to the widely held belief that they challenge many of the assumptions of classical cognitive science. In the domain of language acquisition, for example, there has been much interest in the claim that PDP models might undermine nativism. Related arguments based on PDP learning have also been given against Fodor's ant...

In this paper we take a fresh look at the partition-driven placement (PDP) paradigm for standard-cell placement for wire-length minimization. The goal is to develop several new algorithms for incorporation into a PDP framework that can rectify the well-known drawbacks of traditional PDP (increasingly localized view of nets with increasing levels of the partitioning tree, min-cut objective, inac...

Pyruvate dehydrogenase (PDH) plays an important role in regulating carbohydrate metabolism in skeletal muscle. PDH is activated by PDH phosphatase (PDP) and deactivated by PDH kinase (PDK). Obesity has a large negative impact on skeletal muscle carbohydrate metabolism, whereas endurance training has been shown to improve regulatory control of skeletal muscle carbohydrate metabolism, more so whe...

Parallel Distributed Processing (PDP) models have always been considered a particularly likely framework for achieving neural-like simulations of cognitive function. To date, however, minimal contact has been made between PDP models and physiological data from the brain performing cognitive tasks. We present an implemented PDP model of Event-Related Potential (ERP) data on visual word recogniti...

Pyruvate dehydrogenase (PDH) is a mitochondrial enzyme responsible for regulating the conversion of pyruvate to acetyl-CoA for use in the tricarboxylic acid cycle. PDH is regulated through phosphorylation and inactivation by PDH kinase (PDK) and dephosphorylation and activation by PDH phosphatase (PDP). The effect of endurance training on PDK in humans has been investigated; however, to date no...

•Discrete hierarchies are ubiquitous in intelligent systems. • The Poisson-Dirichlet process (PDP ) [1] allow statistical inference and learning on discrete hierarchies, e.g., hierarchy of Dirichlet distributions. • Applications of the PDP/HPDP include but not limited to: – Topic modeling: Finding meaningful topics discussed in large set of documents. Beneficial to automatic document analysis a...
