It is well-known that there exists a critical control weighting parameter which results in an unstable controller design if the uncontrolled system is unstable or nonminimum phase and a single stage cost functional is used. The purpose of this note is to show that the determination of this parameter reduces to solving a root-locus problem.

RFID technology can improve inventory and pipeline visibility. However, there is scarce research on how to tactically and operationally make use of RFID-captured data. The purpose of this paper is thus to explore the advantages and characteristics, from a material control perspective, of keeping track of goods in real time in a supply chain. A framework regarding the potential gains of tracking u

Abstract in Spanish Este trabajo presenta algunas reflexiones preliminares acerca del desarrollo rural en el nordeste de Argentina a la luz de los cambios socio-económicos y políticos acontecidos en los últimos veinte años aproximadamente. Así, por ejemplo, los procesos de descentralización que han tenido lugar en este país durante la década de 1990 ilustran la complejidad de las estrategias de de

Double-stranded DNA bacteriophages are highly stressed under the high internal pressure that is described as stored energy. Most of them eject their genome into the host bacteria via receptor binding. In the previous work, isothermal titration calorimtery (ITC) was used, for first time, to directly measure the heat released during DNA ejection from the phage lambda, triggered in solution by solubi

A statistical analysis of amplitudes corresponding to multipath components in outdoor (urban/suburban) channels is presented. The study is based on short-term complex impulse response measurements conducted in Stockholm at 1.88 GHz carrier frequency with 5 MHz bandwidth. The actual investigations show that the Rice distribution gives the best fitting in the Kramer-von-Mises sense. Further it is sh

Neuronal cell suspensions prepared from the ventral mesencephalon and the septal-diagonal band area of rat embryos were implanted into the depth of the intact neostriatum or hippocampus of 21-23 month old female rats. Graft survival, assessed 3-4 months after grafting, was comparable to that seen in our previous studies of young adult recipients. Fibre outgrowth into the host brain was evaluated i

Medical education seemingly immune to discussions of gender. Study indicates gender perspective in teaching is lacking Maria Norstedt, Karen Davies Läkartidningen 2003:100;2056-62 This article builds upon qualitative interviews with teachers and students in the medical education at Lund university. The results found that a gender perspective is understood primarily in terms of the biological body.
