This paper describes the Power System Blockset (PSB) from The MathWorks, Natick, MA, which is a new software package for the simulation of electric circuits, power systems, power electronic devices, and electric drives. The PSB is developed in the graphical Simulink environment of the general-purpose Matlab software. This blockset inherits a number of advantages from its development environment...

In the CERN PS Booster (PSB), longitudinal Beam Transfer Function (BTF) measurements are used to determine the energy spectrum of the linac beam injected and coasting on an extended flat bottom of the magnet cycle. The short duration (about 10 ms) of the measurement and coherent signals from density structure of the injected beam yielded strongly fluctuating results, and the system fell into di...

Presently a new accelerator complex is being planned at CERN, which will replaced the ageing Proton Synchrotron (PS). A high-power160 MeV H linac (Linac 4) will replace the present 50 MeV proton linac injector [1], a 5 GeV Superconducting Proton Linac (SPL) will replace the 1.4 GeV PS Booster (PSB) [2] and a 50 GeV synchrotron (PS 2) will replace the 26 GeV PS [3]. A tentative layout of the pla...

A study was conducted to determine the efficacy of applying ground magnesium limestone (GML) or ground basalt in combination with bio-fertilizer to sustain rice production on an acid sulfate soil in Malaysia. Soils from Kelantan Plains, Malaysia, were treated with GML, ground basalt, bio-fertilizer, GML + bio-fertilizer, and ground basalt + bio-fertilizer (4 t ha 1 each). Results showed that so...

D D The fractional part of the betatron tune for a circular accelerator can be measured by observing beam oscillations on a position pick-up. In frequency domain the betatron frequency is seen as sidebands on either side of the revolution harmonics. Usually beam signal pulses from the pick-up are very short with respect to the revolution period, resulting in a broadband spectrum. Classical tune...

Now that major milestones have been reached by both the public and private sectors in the quest for the human genome sequence, the focus is shifting to the genetic variability of our species. Lying buried in human genetic variability is the source not only of all genetic disease, but the entire range of normal phenotypic variation, including susceptibilities to pathogens and environmental facto...

In this survey we focus on bioinformatics literature involving computational algorithms from authors in Taiwan. In a typical scenario of discrete algorithm design we have a single objective to optimize or a certain property to recognize. One can expect either to give a polynomial time algorithm for the problem or to show that it is NP-complete/hard. However, biological experiments are never fla...

The physical protein contact map is a distinctive signature of its folded structure and contains information on all the subtle interactions within contacts among residues responsible of protein stability/function. It is a common believe that an efficient prediction of protein contact maps from the protein chains will help in finding solutions to the protein folding problem. It is therefore urge...

In this paper, we develop an analysis of the Needham-Schroeder Public-Key Protocol (NSPK) using a P system approach. This analysis is used to validate the protocol and exhibits, as expected, a well known logical attack. The novelty of our approach is to use MGS, a P system like formalism, to find the attack by a systematic state exploration. The use of multiset rewriting has already been advoca...
