Motivated by the potential to reuse the architecture in place for an analog sum-product decoder, and thus reduce circuit space, we show how an encoder may be constructed for a class of reversible LDPC codes. We review the design of the analog sum-product decoder for subthreshold CMOS current mode operation and then show how the architecture may be reused for encoding. The encoder circuit operat...

Several methods and techniques are systematized for transforming a current product selling business into a reuse business, which is defined as “products are collected and reused in the same or other markets within a framework of rental or lease service”. The proposed methodology consists of six technical elements. There are two major approaches to making a decision to start a reuse business: a ...

Large-scale linguistic annotation is currently employed for a wide range of purposes, including comparing communication under different conditions, testing psycholinguistic hypotheses, and training natural language engines. Current software support for linguistic annotation is poor, with much of it written for one-off tasks using special purpose data representations and data handling routines. ...

Discontinuity meshing has greatly enhanced the visual and numerical accuracy of radiosity solutions. However, its computational expense means that it cannot be used in dynamic interactive environments with current hardware. Techniques are proposed which allow the discontinuity information to be reused as the environment changes. These techniques complement existing dynamic radiosity methods whi...

Current interconnect standards providing hardware support for quality of service (QoS) consider up to 16 virtual channels (VCs) for this purpose. However, most implementations do not offer so many VCs because they increase the complexity of the switch and the scheduling delays. In this paper, we show that this number of VCs can be significantly reduced. Some of the scheduling decisions made at ...

Software developers’ community understands and forcedly accepts that software development in its current state is rather art than an engineering process. This means that qualitative software is a piece-work or a craftwork. Such an item usually is expensive, and cannot be stock-produced. However, in the modern world software users want to see and to use a qualitative and relatively cheap product...

Experience with data exchange standards has shown considerable limitations in their integration in commercial tools and their interoperability. The current trend is to use XML as a mean of exchanging data. We present in this paper a new standard approach for querying and exporting data from PLM in XML format using XPath/XQuery languages. An abstraction effort and an adapter implementation were ...

Service orientation is a new software engineering paradigm that introduces opportunities as well as challenges. Although existing processes and practices can be reused for service oriented development, novel techniques are required to address unique SOA requirements. Work in this area is quite active and only recently is producing some initial results. The aim of this paper is to present a stat...

We present a reduction from a new logic extending van der Meyden’s dynamic logic of permission (DLP) into propositional dynamic logic (PDL), providing a 2EXPTIME decision procedure and showing that all the machinery for PDL can be reused for reasoning about dynamic policies. As a sideeffect, we establish that DLP is EXPTIME-complete. The logic we introduce extends the logic DLP so that the poli...

This paper discusses dynamic reconfiguration of applications at the architectural level. Current work on dynamic aspects of software architectures has focused on planned reconfigurations controlled from the outside. In this paper we present a different approach, using architectural agents. The agent-enabled architecture descriptions will be executable and have a mechanism to describe reconfigur...
