Putting Research into Use (RIU): Technology Development for the Poor Farmer in Low Income countries
The Research Into Use programme aims to help agricultural research projects put its existing stock of knowledge into practical use rather than investing in new scientific research. In doing this, it hopes to increase the reach of the scientific projects in low-income countries and set up productive, sustainable and high impact technologic development projects
Space Station attached payloads
The Space Station Freedom is being designed and developed with user requirements being used to shape the configuration. Plans include accommodation provisions for a wide variety of attached payloads including the Earth sciences research activities which are the focus of this conference. The station program is even beginning some preliminary payload manifesting which involves planning for accommodation of payload during the station's assembly flights. Potential payload organizations should be aware of the station's plans for payload accommodations so as to guide their own payload activities for future space station use
Understanding best practices in control engineering education using the concept of TPACK
This study aimed to design an integrated pedagogical approach to advance introductory Process Control Engineering Education through the application of the Technological Pedagogical Content Knowledge (TPACK) framework, and evaluating its impact on student learning. The research is initially being undertaken at Nottingham Trent University, UK but we will next adapt it to a case study in Libya. This paper aims to strengthen the teaching of introductory Process Control by using appropriate approach es in universities to improve the learning outcomes for students. From this work a new schematic for teaching Process Control ha s be en developed and, moreover, a thoughtful best practice in introducing Process Control in engineering education can be developed
An Optics Field Site for Auroral Studies
The earlier orbits and ephemerides for the Soviet satellites were not sufficiently
accurate to be very useful in making observations in Alaska. Extrapolations
from our own observations gave better predictions. This merely pointed out the fact
that rough observations of meridian transits at high latitudes will give better values
of the inclination of the orbit than precision observations at low latitudes. Hence,
it was decided to observe visually the meridian transits estimating the altitude by
noting the position with respect to the stars or using crude alidade measurements.
The times of the earlier observations were observed on a watch or clock and the clock
correction obtained from WWV. Later the times were determined with the aid of stop
watches, taking time intervals from WWV signals.
This rather meager program of optical observations of the Soviet satellites was
undertaken to give supplementary data for use of the radio observations, and particularly
to assist in the prediction of position of the satellite so that the 61-foot
radar of Stanford Research Institute could be set accurately enough to observe it
(the beam width at the half-power points is about 3°).
This report contains primarily the visual observations made at the Geophysical
Institute by various members of the staff, and a series of observations by Olaf
Halverson at Nome, Alaska. In addition there is a short discussion of the geometry
of the trajectory, the illumination of a circumpolar satellite, and a note on the
evaluation of Brouwer's moment factors.IGY Project No. 1.14

Space activities in Glasgow; advanced microspacecraft from Scotland
The City of Glasgow is renowned for its engineering and technological innovation; famous Glaswegian
inventors and academics include James Watt (Steam Engine) and John Logie Baird (television), amongst many
others. Contemporary Glasgow continues to pioneer and invent in a multitude of areas of science and
technology and has become a centre of excellence in many fields of engineering; including spacecraft
engineering.
This paper will discuss how Clyde Space Ltd and the space groups at both Glasgow and Strathclyde
Universities are combining their knowledge and expertise to develop an advanced microspacecraft platform that
will enable a step change in the utility value of miniature spacecraft. The paper will also explore how the
relationship between the academic and industrial partners works in practice and the steps that have been taken
to harness resulting innovation to create space industry jobs within a city that was, until recently, void of any
commercial space activity
Entanglement and entropy engineering of atomic two-qubit states
We propose a scheme employing quantum-reservoir engineering to controllably
entangle the internal states of two atoms trapped in a high finesse optical
cavity. Using laser and cavity fields to drive two separate Raman transitions
between metastable atomic ground states, a system is realized corresponding to
a pair of two-state atoms coupled collectively to a squeezed reservoir.
Phase-sensitive reservoir correlations lead to entanglement between the atoms,
and, via local unitary transformations and adjustment of the degree and purity
of squeezing, one can prepare entangled mixed states with any allowed
combination of linear entropy and entanglement of formation.Comment: 4 pages, 5 figures, REVTe
