A UNIX operating system together with a complete user environment has been implemented on the VAX-11/780 computer manufactured by Digital Equipment Corporation. The VAX-11/780 system provides 32-bit addresses and data. It uses the same input/output devices and the PDP-11 family and is controlled through a console computer which can be remotely accessed. Additionally, the VAX-11/780 is priced ne...

Posturography is routinely used to qualitatively assess one of the cardinal symptoms of Parkinson’s disease – postural instability. While most measures of balance control are derived from displacement of the center of pressure there is evidence that such control is more likely to be velocity-based. We performed static posturographic tests (eyes open and eyes closed) during quiet standing in nar...

Service function chaining (SFC) is an indispensable technique for Internet service providers to efficiently manage their networks. However, SFC poses requirements of additional processing time functions (SFs) and increased routing owing detoured paths. In this paper, we introduce the use a programmable data plane (PDP) reduce times in SFC. We first classify existing PDP-empowered schemes analyz...

After decades of research and development, plasma displays are finally beginning to appear in the commercial and consumer markets. Following a short review on the basic principles of direct and alternating current plasma displays, we present a summary of the status of color plasma displays. Plasma display panels (PDPs) have finally achieved luminance and efficiency values on par with hi-definit...

T his special issue of Computer is about recent efforts to produce T hardware and software architectures that support artificial intelligence (Al) applications. The earliest computer design to support Al processing was the implementation of Lisp on the PDP-6 computer and its successors, the PDP-10 and PDP-20, all made by the Digital Equipment Corporation. The half-word instructions and the stac...

This paper aims at closing the gap between early phases (e.g. design) and later phases (e.g. procurement or production) of the Product Development Process (PDP) by proposing a Virtual Product Model (VPM) as a collection of individual components (VPMCs) without the need for a static structure. Based on an analysis of the requirements on product development in the automotive industry, the main pr...

Provable data possession (PDP) is a technique for ensuring the integrity of data in storage outsourcing. In this paper, we address the construction of an efficient PDP scheme for distributed cloud storage to support the scalability of service and data migration, in which we consider the existence of multiple cloud service providers to cooperatively store and maintain the clients’ data. We prese...

This paper presents a method to Designing Ripple Carry Adder using CMOS Full-Adders for Energy-Efficient Arithmetic Applications. We present two high-speed and low-power full-adder cells de-signed with an alternative internal logic structure and pass-transistor logic styles that lead to have a reduced powerdelay product (PDP). We carried out a comparison against other full-adders reported as ha...

This paper present new energy efficient methods of designing switches and routing interconnects inside FPGA using novel variants of Dynamic Threshold MOS (DTMOS) instead of traditional NMOS pass transistor based switches and interconnects. The extra needed transistors can be easily shared, in multiplexer based routing architecture of FPGA, keeping area overhead to be minimum. Extensive transist...

The neuropsychological evaluation of memory by traditional tests raises questions about their ecological validity, as the results on these tests often have little relation to the memory complaints. In an attempt to explain this lack of relationship, the present study had two objectives: (1) explore the ecological superiority of the Process Dissociation Procedure (PDP) over traditional memory te...
