James Webb Space Telescope Optical Telescope Element (OTE) is a three mirror anastigmat consisting of a 6.5 m primary mirror (PM), secondary mirror (SM) and a tertiary mirror. The primary mirror is made out of 18 segments. The telescope and instruments will be assembled at Goddard Space Flight Center (GSFC) to make it the Optical Telescope Element-Integrated Science Instrument Module (OTIS). Th...

This research attempts to determine whether case studies from fieldwork and secondary data on product information management systems (PIMS) map to Stein and Zwass ’ (I 995) framework for an organizational memory information system (OTIS). Overall, we$nd support for the two layers in the framework, andfor organizational effectiveness from an OMIS. The secondary data suggest first and second orde...

Pervasive computing is at an exciting stage of its evolution, with an increasing number of devices of various shapes and sizes appearing in our everyday surroundings. In such an environment, the need to utilise application sessions within and across device rich spaces becomes apparent. This paper introduces the concept of mobile sessions for smart space environments, by outlining a candidate fr...

Solute transport in streams is governed by a suite of hydrologie and chemical processes. Interactions between hydrologie processes and chemical reactions may be quantified through a combination of field-scale experimentation and simulation modeling. Two mathematical models that simulate conservative and nonconservative solute transport in streams are presented. A model for conservative solutes ...

Small streams in urbanized rural areas receive loads of P from various, often episodic, sources. This paper addresses, through a tracer test with 32P, retention and transport pulse input phosphorus 2.6 km long stretch channelized second-order lowland stream. Tritiated water was introduced alongside the 32P-labelled ortophosphate order to isolate influence hydrodynamic factors on behavior. Trace...

Charles Otis Whitman [5] was an extremely curious and driven researcher who was not content to limit himself to one field of expertise. Among the fields of study to which he made significant contributions were: embryology [6]; morphology [7], or the form of living organisms and the relationships between their structures; natural history [8]; and behavior. Whitman served as director of several p...
