    This paper aims to present an overview of how mentoring schemes could be applied to a University setting to assist with the transfer of direct entry students (those who join degree programmes in years 2 or 3) onto current courses. Heirdsfield, Walker, Walsh and Wilss (2008) highlight that money is invested into attracting students to study at Universities; however little is invested into retaining students. Direct entry students in particular can suffer from problems related to transition to a University setting. These may include „feelings of isolation and uncertainty‟ (Cantwell & Scevak, 2004). The application of a mentoring scheme could help reduce the problems which new and direct students may encounter. However, the concept of the student-mentor relationship is complex (Wilkes, 2006) and schemes need to be constructed with knowledge of current research and careful planning. Few University based mentoring schemes have published critical evaluations of their programmes, however research in other types of organisations and settings can provide insight into how such schemes could be applied to a University setting. It is important to have guidelines for those who wish to adopt such schemes. If the mentoring scheme is carried out inappropriately, it may have damaging effects on both the mentee and mentor (Tabbron, Macaulay & Cook, 1997)

    Allocation of tasks to specialized processors: A planning approach

    Get PDF
    This paper addresses the problem of scheduling randomly arriving tasks of different types at a diversified service system. Servers at such a system differ in that each may specialize in one task type, but can also perform others perhaps less rapidly and adequately than does a specialist. We consider the issue of how much redirection of tasks from specialists to non-specialists may be desirable in such a system and propose a static model in which tasks are randomly assigned to servers. Two scheduling strategies for individual servers are also considered: one in which each server performs the tasks assigned to him or her in order of their arrival and the second in which each server schedules his or her workload optimally. The problems for finding the best random assignment probabilities are formulated as mathematical programs. Results from a numerical example provide information that is both informative and useful in decision-making

    Data analysis and modeling of Arctic sea ice subsurface roughness

    Get PDF
    Statistical data analysis and models are used to characterize and summarize the roughness of the underside of sea ice in the Arctic. Keel spacings and depths are modeled by sculptured exponentials, and by gamma distributions. The data studied was obtained by upward looking sonar on the submarine GURNARD during April, 1976, in the Beaufort Sea. The models and methods should be more widely applicablesupported in part by the Naval Postgraduate School Foundation Research Program and by the Office of Naval Research, Arlington, VA.http://archive.org/details/dataanalysismode00gaveN0001482WR20043N

    Superorbital expansion tube operation: estimates of flow conditions via numerical simulation

    Get PDF
    Two new operating conditions of the X3 superorbital expansion tube are studied experimentally and numerically. A two-stage numerical simulation is used to model the flow processes within the whole facility, from the compressed driver gas, through the initial shock-processing of the test gas and then through the unsteady expansion process to the final test flow state. Experimental measurements provide static pressure histories at particular points along the shock and acceleration tubes while the numerical simulations provide complementary information on gas density, temperature and composition. Operating condition properties such as shock speed are both observed in the experiment and produced as a result of the simulation are used to check the reliability of the numerical simulations

    Relatie tussen microklimaat en vaasleven bij roos

    Get PDF
    Bij snijrozen is getracht een beeld te krijgen van het microklimaat in het gewas met sensoren die de temperatuur van knop en blad meten, aangevuld met metingen van RV en temperatuur van de omringende lucht. Gelijktijdig is bij 2 cultivars, ‘Passion’ en ‘Avalanche Peach’, en op twee plekken in de kas het vaasleven bepaald. Op die manier werd gehoopt een indicatie te vinden voor de invloed van het microklimaat op het optreden van met name botrytis. De meting bleek niet in staat om een direct verband aan te tonen tussen microklimaat en botrytis. Wel werd duidelijk dat de meest waarschijnlijke oorzaak gezocht moet worden in perioden dat niet belicht wordt in koude luchtstromen in de kas als gevolg van kieren in het scherm en van uitstraling van de knoppen naar een koude hemel. Meten van de temperaturen van knop en blad bleek door de kwetsbaarheid van het thermokoppel moeilijk uitvoerbaar, maar kan eenvoudig vervangen worden door een thermische camera. Aanvullend zal er echter een meetmethode ontwikkeld moeten worden om de RV in de grenslaag rondom knop of blad betrouwbaar te kunnen meten voordat een meting van het microklimaat praktische waarde kan hebben bij het voorspellen van de kans op natslag
