    Get PDF
    Development of varactor diode assembly overcomes parasitic reactances of conventional varactor packages. In specially constructed assembly very high idler-frequency to signal-frequency ratios are used to obtain low-noise operation over maximum bandwidth

    Opportunities for Achieving Competence in Personal Attributes for Personal & Professional Developments

    Get PDF
    This document lists descriptions of generic skills / personal attributes that are useful to consider in personal and professional development. It also describes some general competencies and offers some thoughts on how to create opportunities to achieve competence with a bias towards computer science & IT students. It is based on advice given by Career Destinations at the University of Southampton and other universitie

    Versioning RLOs as ‘study skills toolkits’ for different user groups and developing community tools to support sharing and customisation

    No full text
    As patterns of need in twenty-first century higher education change so must the solutions. E-learning solutions, in particular, need to be adaptive to fit a range of teaching and learning situations. eLanguages, a research and development unit at the University of Southampton, develops online toolkits of reusable learning objects (RLOs) in Study Skills that can be versioned for different student user groups. Underpinning them is an approach which seeks to deliver high quality content and be cost-effective. Reusability and versatility are central to this. With the creation of a large base of RLOs has come recognition of the need to manage and customise these resources easily and a suite of tools enabling such actions has been developed. This paper will present the toolkits and the pedagogic design of the RLOs. The web-based tools to support management and customisation of RLOs, and potentially facilitate new toolkit creation, will also be introduced

    Crime and Punishment Again: The Economic Approach with a Psychological Twist

    Get PDF
    Akerlof and Dickens (1982) suggested that in a model of criminal behavior which considered the effects of cognitive dissonance, increasing the severity of punishment could increase the crime rate. This paper demonstrates that that conjecture was correct. With cognitive dissonance, people may have to rationalize not committing crimes under normal circumstances if punishment is not severe. The rationalization may lead them to underestimate the expected utility of committing crimes when opportunities present themselves. If punishment is severe, then rationalization may not be necessary and people may be more likely to commit crimes when opportunities arise.

    Technique for using a geometry and visualization system to monitor and manipulate information in other codes

    Get PDF
    A technique was developed to allow the Aero Grid and Paneling System (AGPS), a geometry and visualization system, to be used as a dynamic real-time geometry monitor, manipulator, and interrogator for other codes. This technique involves the direct connection of AGPS with one or more external codes through the use of Unix pipes. AGPS has several commands that control communication with the external program. The external program uses several special subroutines that allow simple, direct communication with AGPS. The external program creates AGPS command lines and transmits the line over the pipes or communicates on a subroutine level. AGPS executes the commands, displays graphics/geometry information, and transmits the required solutions back to the external program. The basic ideas discussed in this paper could easily be implemented in other graphics/geometry systems currently in use or under development
