Spaceborne sensors (1983-2000 AD): A forecast of technology

A technical review and forecast of space technology as it applies to spaceborne sensors for future NASA missions is presented. A format for categorization of sensor systems covering the entire electromagnetic spectrum, including particles and fields is developed. Major generic sensor systems are related to their subsystems, components, and to basic research and development. General supporting technologies such as cryogenics, optical design, and data processing electronics are addressed where appropriate. The dependence of many classes of instruments on common components, basic R&D and support technologies is also illustrated. A forecast of important system designs and instrument and component performance parameters is provided for the 1983-2000 AD time frame. Some insight into the scientific and applications capabilities and goals of the sensor systems is also given

A domain specific language for contextual design

This paper examines the role of user-centered design (UCD) approaches to design and implementation of a mobile social software application to support student social workers in their work place. The experience of using a variant of UCD is outlined. The principles and expected norms of UCD raised a number of key lessons. It is proposed that these problems and lessons are a result of the inadequacy of precision of modeling the outcomes of UCD, which prevents model driven approaches to method integration between UCD approaches. Given this, it is proposed that the Contextual Design method is a good candidate for enhancing with model driven principles. A subset of the Work model focussing on Cultural and Flow models are described using a domain specific language and supporting tool built using the MetaEdit+ platform

Goal based alignment of enterprise architectures

Business and IT alignment remains an ongoing concern for organizations. Enterprise Architecture has emerged as a possible tool for understanding and planning for BIA, but the current range of methods and frameworks for EA do not support precise measurement. In this paper, we propose a set of technologies and concepts - notably goals and computable functions which can be used to provide a measure of equivalence between as-is and to-be enterprise architectures. The goals enable description of business level requirements whilst the functions enable the goals to be evaluated at a technical architecture level. The technology is evaluated with a detailed and authentic case study from higher education

bCMS in LEAP

This paper contains an overview of the features of the LEAP component based executable modelling language applied to the bCMS Crisis Management System Case Study. The paper aims to show the key features of the LEAP technology in terms of various aspects of the case study

Radio detection of H2O in comet Bradfield (1974b)

Results of observations of comet Bradfield using the Haystack telescope are summarized with emphasis on the detection of the 1.35 cm emission line of water in the comet. The excitation of water and methyl cyanide in comets is briefly considered

Inflatable stretcher to transport patients

Inflatable plastic bag inside strong, inflexible outer bag facilitates emergency transport of seriously burned or disabled patients. When the bag is inflated the patient is completely immobilized and cushioned from external shock. Air for breathing, temperature controls and communications may be provided by appropriate plug-in connections
