This paper presents the extraction of a legal access control policy and a conflict resolution policy from the EU Data Protection Directive [1]. These policies are installed in a multi-policy authorization infrastructure described in [2, 3]. A Legal Policy Decision Point (PDP) is constructed with a legal access control policy to provide automated decisions based on the relevant legal provisions....

BACKGROUND Symptomatology and physiology differ between men and women and across the menstrual cycle in irritable bowel syndrome (IBS). Ovarian hormones influence 5-hydroxytryptamine (5-HT), an amine known to play a role in gut motor-sensory function. AIM To assess the effects of gender and menstrual status on platelet-depleted plasma (PDP) 5-HT concentration in IBS patients with diarrhoea (I...

The pick-up and delivery problem (PDP) consists in finding a set of optimal routes for a fleet of vehicles respecting the precedence and pairing constraints and visiting all transportation requests. The transport of personnel on oil platforms is a real application of PDP which we are interested in. The problem is modeled as a set covering problem that is solved via a column generation technique...

The PDP(Partial Dominant Pruning) method is known as most practical method to reduce overlapped broadcasting messages by designating forward node as in-fly type when broadcasting occurs in the mobile wireless network with directional antenna. In this paper, we introduce DPDP(Directional PDP) that reduces not only number of nodes but number of used antenna elements simultaneously. By simulation,...

The Pickup and Delivery Problem (PDP) consists in defining a set of routes that satisfy transportation requests between a pickup point and a delivery point. This paper addresses a variant of the PDP where the requests are transportation demands arising from disabled persons. Vehicle passengers can change of vehicle during their trip on specific locations called “transfer points”. Solving this v...

PURPOSE OF REVIEW We discuss features of Parkinson's disease psychosis (PDP) including symptomology and pathophysiology. Treatment options, including non-pharmacologic strategies, dose reduction of offending agents, and the addition of non-dopaminergic antipsychotics, are addressed. The efficacy of second-generation antipsychotics and novel agents is examined. RECENT FINDINGS Pimavanserin, a ...

Programming is an activity centred primarily around the keyboard which is not necessarily the optimal input device for all users. Little research has taken place into alternative input devices for programming despite huge advances in handwriting and voice recognition for natural language. This project explored using a pen as the primary input device for programming. A variety of different metho...

Multimedia applications in general and video processing, such as the MPEG4 Visual stream decoders, in particular are increasingly popular and important workloads for future embedded systems. Due to the high computational requirements, the need for low power, high performance embedded processors for multimedia applications is growing very fast. This paper proposes a new data prefetch mechanism c...

This work provides both a speci cation and a proof of correctness for the system PDP (Prolog Distributed Processor) which make use of Abstract State Machines (ASMs). PDP is a recomputation-based model for parallel execution of Prolog on distributed memory. The system exploits OR parallelism, Independent AND parallelism as well as the combination of both. The veri cation process starts from the ...

Oreopithecus bambolii is a Late Miocene ape from Italy, first described in the late 19th century. Its interpretation is still highly controversial, especially in reference to its hand proportions and thumb morphology. In this study, the authors provide detailed descriptions of the available Oreopithecus pollical distal phalanx (PDP) specimens, as well as bivariate and multivariate morphometric ...
