Equipment concept design and development plans for microgravity science and applications research on space station: Combustion tunnel, laser diagnostic system, advanced modular furnace, integrated electronics laboratory

Taking advantage of the microgravity environment of space NASA has initiated the preliminary design of a permanently manned space station that will support technological advances in process science and stimulate the development of new and improved materials having applications across the commercial spectrum. Previous studies have been performed to define from the researcher's perspective, the requirements for laboratory equipment to accommodate microgravity experiments on the space station. Functional requirements for the identified experimental apparatus and support equipment were determined. From these hardware requirements, several items were selected for concept designs and subsequent formulation of development plans. This report documents the concept designs and development plans for two items of experiment apparatus - the Combustion Tunnel and the Advanced Modular Furnace, and two items of support equipment the Laser Diagnostic System and the Integrated Electronics Laboratory. For each concept design, key technology developments were identified that are required to enable or enhance the development of the respective hardware

A technology white paper on improving the efficiency of social safety net program delivery in low income countries an introduction to available and emerging mobile technologies

This document outlines various available and emerging information and communication technologies (ICTs) and provides a framework to assess how these technologies may be used to improve the efficiency of the delivery of safety net programs. These technologies include: mobile computing, biometrics, satellite communications, simple and smart cards, global positioning systems, radio frequency identification tags, automated teller machines and solar power. Their use in the administration, delivery and monitoring of SSN programs offers numerous advantages including increased accuracy, reliability and timeliness of information, performance measurement and service provider accountability. However, these new and emerging technologies typically require higher initial investment costs that benefit current and future time periods. The optimal solution to design an advanced and efficient delivery system for a safety net program may be a combination of traditional service delivery methods and new technologies that draws on a needs assessment that accounts for local conditions and program characteristics.

Who wrote this scientific text?

The IEEE bibliographic database contains a number of proven duplications with indication of the original paper(s) copied. This corpus is used to test a method for the detection of hidden intertextuality (commonly named "plagiarism"). The intertextual distance, combined with the sliding window and with various classification techniques, identifies these duplications with a very low risk of error. These experiments also show that several factors blur the identity of the scientific author, including variable group authorship and the high levels of intertextuality accepted, and sometimes desired, in scientific papers on the same topic

Sensor-based management systems based on RFID technology

Παρατηρήσεις έκδοσης: λείπουν οι σελίδες 78, 102 από το φυσικό τεκμήριο.In this diploma thesis, the RFID technology is analyzed (operating principles, readers' and tags hardware, coding, modulation, anticollision procedures, frequencies, standards, applications). Moreover, a protocol to synchronize readers working in a multi-reader multi-tag environment is proposed. The protocol is applied to the store shelf scanning application and further refined to meet the requirements of this specific application
