Success criteria for international joint ventures: the experience of Malaysian contractors in the Middle East

The overall objective of this paper is to produce success criteria considered critical in international joint ventures (IJV), specifically between Malaysian and foreign contractors outside Malaysia. The recognition of such criteria will contribute to the identification of non-viable projects and will enable improvements to be made to the IJV and other similar economies. Data specific to the present study was collected through face-to-face interviews, which were carried out with the General Manager of the respective companies to provide detailed information on their company structure, management and experience of any joint venture projects undertaken outside Malaysia. The main findings from the interviews are that the critical factors in IJV partner selection criteria were related to the reputation, inter-partner trust, experience, personal knowledge of the partner organizations, commitment and human resources management. The employment of Malaysian sub-contractors also lessened the complexity of management. This is largely due to the familiarity of working with fellow Malaysians in the Middle East

Isovector channel of quark-meson-coupling model and its effect on symmetry energy

The non-relativistic approximation of the quark-meson-coupling model has been discussed and compared with the Skyrme-Hartree-Fock model which includes spin exchanges. Calculations show that the spin-exchange interaction has important effect on the descriptions of finite nuclei and nuclear matter through the Fock exchange. Also in the quark-meson-coupling model, it is the Fock exchange that leads to a nonlinear density-dependent isovector channel and changes the density-dependent behavior of the symmetry energy.Comment: 20 pages, 9 figures and 1 table, accepted for publication in Nuclear Physics

The structural and electrical properties of thermally grown TiO2 thin films

We studied the structural and electrical properties of TiO2 thin films grown by thermal oxidation of e-beam evaporated Ti layers on Si substrates. Time of flight secondary ion mass spectroscopy (TOF-SIMS) was used to analyse the interfacial and chemical composition of the TiO2 thin films. Metal oxide semiconductor (MOS) capacitors with Pt or Al as the top electrode were fabricated to analyse electrical properties of the TiO2 thin films. We show that the reactivity of the Al top contact affects electrical properties of the oxide layers. The current transport mechanism in the TiO2 thin films is shown to be Poole–Frenkel (P–F) emission at room temperature. At 84 K, Fowler– Nordheim (F–N) tunnelling and trap-assisted tunnelling are observed. By comparing the electrical characteristics of thermally grown TiO2 thin films with the properties of those grown by other techniques reported in the literature, we suggest that, irrespective of the deposition technique, annealing of as-deposited TiO2 in O2 is a similar process to thermal oxidation of Ti thin films

Silicon micromachined waveguides for millimeter-wave and submillimeter-wave frequencies

The development of micromachining techniques to create silicon-based waveguide circuits, which can operate up to high submillimeter-wave frequencies, is reported. As a first step, a WR-10 waveguide has been fabricated from (110) silicon wafers. Insertion loss measurements on a gold-plated silicon waveguide show performance comparable to that of standard metal waveguides. It is suggested that active devices and planar circuits can be integrated with the waveguides, solving the traditional mounting problems
