    Notes: In the three-dimensional (3-D) eddy current calculations, the obtaining of an accurate numerical solution with reasonable size and less computation efforts is still undertaken in many recent articles. Nowadays, such a solution becomes urgently required for designing and developing the electromagnetic confinement application, where the problem is not only 3-D but also involves more than one conducting region having a free boundary that is unknown a priori. For this class of applications, the present paper is devoted to discuss the developing of a 3-D iterative solution proposed for the analysis of an electromagnetic continuous casting (EMC) of an aluminum rectangular ingot installed in the Egyptalum Company. This solution is based on a derived 3-D Boundary Element (BE)—Impedance Boundary Condition (IBC) formulation, which leads to a significant reduction in the CPU time and the calculation efforts, as compared to the use of the regular BE formulation. In the present iterative solution, the IBC is applied to the resistively molten aluminum region, while the full BE formulation is used to present the field shaping screen. The validity of this iterative solution is tested by predicting the equilibrium meniscus shape of the free surface for an EMC mold having the size of 1050×280 mm for which experimental measurements for both the meniscus and the total active power supplied are available. Numerical results showing the magnetic flux density distributions over the boundaries of this mold are presented. The corresponding total surface power induced are estimated and compared with the corresponding actual (experimental) values. Also, the meniscus of the molten aluminum free surface is predicted and compared as well.

    Surface impedance-BEM technique for nonlinear TM-eddy current problems (1987)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 61 (1987), S. 3925-3927

    Notes: The impedance boundary condition (IBC) approximation is used to formulate the problem as an exterior one, in other words, in terms of only the exterior fundamental solution. The first order boundary element technique has been used to represent the boundary integral equation numerically. The Gauss–Seidel iterative procedure was applied. The results obtained with the present approach are in good agreement with those obtained experimentally and theoretically by other authors.

    Prediction of mechanical stress effects on the iron loss in electrical machines : The 41st annual conference on magnetism and magnetic materials (1997)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 81 (1997), S. 4119-4121

    Notes: Iron losses can account for a significant portion of the total loss in electrical machines. Nevertheless, although analytical and numerical techniques have been developed for predicting the iron loss density distribution and the total iron loss of various types of machine under any operating load condition, to date these have neglected the effect of mechanical stress. However, during the manufacture of many electrical machines, a significant radial compressive stress can be imposed on the stator lamination stack, by shrink fitting/pressing an outer frame, for example. This paper describes a technique that has been developed for predicting the effect of compressive stress on the iron loss density in lamination materials, and demonstrates its use in calculating the iron loss of a permanent magnet brushless dc motor. © 1997 American Institute of Physics.

    Flow Estimation from Flap-Gate Monitoring (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Water and environment journal 11 (1997), S. 0 
    Details
    ISSN: 1747-6593
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: The measurement of flows and recording of storm events at combined sewer overflows are a key requirement in effective urban pollution management. Staff of Thames Water Utilities have developed a low-cost system based on monitoring the behaviour of flap valves on numerous major river outfalls. The paper presents the development of a modelling approach based on the principle of conservation of angular momentum and its application to experimental data for circular gates. Flow-prediction accuracies, based on the measurement of gate inclination and water depths, in the range ± 20–30%, are found to be achievable for wider gate openings (〈20°) – the recommended calibration offering conservative flow predictions at lower angles.

    Population exposure owing to a borax accident in the Tammuz 2 nuclear reactor (1995)

    Notes: The radiological consequences on the population of a borax accidentin 1994 in the Tammuz 2 nuclear reactor have been postulated. Doseequivalents resulting from the atmospheric release of radionuclidesduring the accident have been estimated for distances ranging from theexclusion zone to 100km from the reactor. Gamma submersion, betasubmersion doses from the plume, inhalation doses and surface exposuredoses have been estimated for various exposure times. Dose equivalentsestimated for the site boundary for an exposure time of 24 hours were1.42 - 10mSv. Accordingly, it seemed that the consequences of theaccident on the population living around Tuwaitha site could only takethe form of stochastic radiation, such as the induction of cancers, andheredity.

    Notes: Develops a graphic simulation system in conjunction with a kinematicerror model to assist management in making investment decisions. UsesTaguchi-type experimental design to predict the robot processcapability. Two sets of charts are created by the system to representthe repeatability and accuracy of the robot performing a givenoperation. These charts are, first, histograms in the x, y, and zdirections and, second, scattered ellipses in the xy, yz, and xz planes.Central to the system are three characteristics: a description of thegeometric error and of the kinematic error; a common function to requestand display a robot moving from one position to the next; and a familyof charts showing the capability of the robot implementing a given task.The results provided by the system can help management to analyse robotprojects concerning robot selection and implement action in a moresystematic manner.

    The partner selection process in international joint ventures (1999)
    Bradford : Emerald
    European journal of marketing 33 (1999), S. 1064-1081 
    Details

    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Economics
    Notes: Argues that the motivation involved in partner selection must be distinguished from the motivation to enter into a joint venture; the latter may be considered the "ends" dimension of motivation while the former is concerned with "means". Thus it is important to distinguish between "task related" factors and "partner related" factors in analyzing the partner selection process. Based on a survey of 42 international joint ventures in Bahrain, respondents rank partner related factors as significantly more important than task factors in selecting a partner. The existence of partner related factors as a separate construct is also confirmed by factor analysis. Further, shows that respondents' factor scores on four factors are significantly related to the corporate history and characteristics of the corporate partner, and to the personal characteristics of the Chief Executive Officer.

    On the relationship between initial motivation, and satisfaction and performance in joint ventures (2004)
    Bradford : Emerald
    European journal of marketing 38 (2004), S. 150-174 
    Details
    ISSN: 0309-0566
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Economics
    Notes: While internalization theory suggests that it is more beneficial for MNEs to internationalize through wholly-owned subsidiaries rather than engaging in joint ventures, this paper argues that the joint venture approach can be successful. Based on a study of 42 international joint ventures in Bahrain, the paper shows that satisfaction after start up is a function of the structure of the initial motivation. Past and anticipated future performance of the joint venture are also functions of the structure of initial motivation, and performance is best viewed as an intervening variable in satisfaction. Environmental factors were more significant than economic factors in the initial motivation decision.
