Abstract: Normal LaTeX and TeX usage does not require touching existing .bst files nor creating new ones. However, BibTEX offers several interesting commands which can be used to do many things apart bibliography generation. In this article, it is demonstrated how customized layouts for a database can be created without much trouble.
Abstract: The increase in the amount of carbon dioxide (CO<sub>2</sub>) in the atmosphere is responsible for problems such as global warming up, rise in the level of the sea, wind pattern changes, etc. It is high time that all countries put the required effort to reduce the CO<sub>2</sub> emission to save the planet. One method to reduce the emission of CO<sub>2</sub> is to maximize the use of renewable energy such as tidal, wind, hydro and solar energy. In tropical countries, solar energy can contribute a lot to the development of the country as well as decreasing the dependency on imported fuel such as petroleum and natural gas. But the equipment associated with renewable sources of energy is quite expensive as compared to equipment used with other fuels. This high initial cost tend to inhibit investment in renewable energy sources.
Abstract: During the last century the hydropower units have been developed from a few megawatts per unit, up to several hundreds megawatts per unit. Over the years the operating conditions have also been changed from the ones that the machines were originally designed. These changes will significantly affect the lifespan of the machines. The hydropower plants are in general old, and large-scale revisions will be performed in the coming years. This implies that new components with new materials and design will be installed to the old machines. To reduce the risk of failures it is essential that better methods for rotor dynamical simulations are developed. In this paper our research on electromagnetic-rotor interaction is summarized. Results are presented on new rotor models in connection with stability, excitation sources for backward/forward whirling and the occurrence of a tangential force.

Abstract: In the process of Shock Response Spectrum calculation, for instance, the forced response of a mechanical Single Degree of Freedom system is determined. This is in most cases performed with the use of a digital filter, preferably one designed with the ramp invariance method. If the sampling frequency is selected properly, a very high precision may be reached. The error may also be predicted. The method may be extended to forced response calculation for mechanical system of virtually any degree of freedom by restricting the calculations to the frequency range of interest. The parameters of the mechanical system may come from analytic expressions, FEM modeling or from experimental data. The method also allows the incorporation on non-linear elements in the system. This leads to simulations of forced response which are must faster and more accurate than those performed in most commercial software.
