Connectivity Infrastructure and Components for POCT Environments - Overall Infrastructure

Connectivity infrastructure, hardware and software components for point-of-care testing (POCT) environments at medium-to-large sized hospitals with expected number of POCT instruments in the order of hundreds or thousands are described. The instruments include both network-ready and non-network-ready devices. The latter are connected to the network by means of a hardware-based Instrument Network Adapter. Instrument messages are converted to standardized form and, depending on message content, are routed and delivered to appropriate destinations by a software-based Message Routing System consisting of a Message Router and a Delivery Agent. Target information systems consist of departmental and central information systems.     

A Technique to Eliminate Redundant Inter-Processor Communication on Parallelizing Compiler TINPAR

Optimizing inter-processor (PE) communication is crucial for parallelizing compilers for message-passing parallel machines to achieve high performance. In this paper, we propose a technique to eliminate redundant inter-PE messages. This technique utilizes data-flow analysis to find a definition point that corresponds to a use point where the definition and the use occur in different PEs. If several read accesses occurred in the same PE use the data defined at the same definition point in another PE, redundant inter-PE messages are eliminated as follows: only one inter-PE communication is performed for the earliest read access and the previously received data are used for the following read. In order to guarantee the consistency of the data, a valid flag and a sent flag are provided for each chunk of received data. The control of these flags is equivalent to the coherence control by the self invalidation on a compiler aided cache coherence scheme.     

GSM Point-to-Point Short Message Service

GSM short message service provides aconnectionless transfer of messages with low-capacityand low-time performance. This article provides atutorial on GSM point-to-point short messaging. Theshort message protocol hierarchy is introduced and the mobileoriginated/terminated messaging procedures aredescribed.     

A methodology for the assessment of nuclear power development scenario

The International Atomic Energy Agency (IAEA) has initiated an International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) in the year 2000. The main objective of INPRO is to help the world community to ensure that clean and safe nuclear energy is available to contribute in fulfilling the energy needs in the 21st century in a sustainable manner. This paper demonstrates a methodology as an application of INPRO assessment for constructing nuclear power development scenarios by the use of IAEA energy optimisation models MESSAGE and DESAE. The scenario for the overall growth of energy and electricity in India is considered as a case study since for several decades India is vigorously pursuing nuclear power development program to meet its growing energy needs. It is evident from this study that in order to develop a realistic nuclear power scenario, it is necessary to generate an overall energy and electricity scenario at first. Within the overall energy-electricity picture it can be envisaged how the nuclear power technology would contribute to supply the future energy needs.

Formulating an optimal long-term energy supply strategy for Syria using MESSAGE model

An optimal long-term energy supply strategy has been formulated based on minimizing the total system costs for the entire study period 2003–2030. The national energy chain was modelled covering all energy levels and conversion technologies. The results indicate that the primary energy will grow at annual average rate of 4.8% arriving 68 Mtoe in 2030. The total installed electric capacity will be optimally expanded from 6885 to 19500 MW in 2030. Furthermore, to ensure supply security the future national energy system will rely mainly upon oil and natural gas (NG) with limited contribution of renewables and nuclear to the end of study period. The share of NG will increase gradually up to 2020 and then retreat. Owing to the continuous decrease of oil production, oil export is expected to vanish in 2012 and the country will import about 63% of its primary energy demand in 2030. Thus, the expected long-term development of national energy sector indicates a hard challenge for the future national economy.     

User Mobility Management in the PCS Network Through the Placement of Hierarchical Databases

The personal communication service (PCS) networkis the next generation wireless communication networkthat allows users to communicate with each other oraccess information in the network any time and anywhere. It is the integration of the cellulartelephone network, the conventional telephone network,and the digital communication network. User movementswithin the network coverage area must be tracked using a database. A hierarchical distributeddatabase architecture localizes database operationscaused by user movements and call setup requests, andreduces traffic in the signaling network. Placement of the database in the signaling networkaffects performance of the network. A new method ispresented to find the best database placement scheme fora given estimation of user movement and call setuprequest rates. This database placement scheme minimizesthe delays of messages resulting from user movements andcall setup requests in the signaling network.
