On the cavity problem for the general linear medium in Electromagnetic Theory

In this paper we study the propagation problem of a time harmonic electro- magnetic field inside a cavity filled with a generic bianisotropic medium. We define the concepts of eigenfrequencies and modes of the cavity and we prove their existence and countability. We extend, in this respect, the theory for the isotropic, homogeneous, lossless cavity.

Linearity of bulk-controlled inverter ring VCO in weak and strong inversion

Frequency modulation in ring VCOs is investigated. Primarily, the linearity of conversion from input voltage to output frequency is considered. Bulk-voltage control of the threshold voltage of the VCO transistors is found to be a very promising approach for applications in frequency /spl Delta//spl Sigma/ converters. Different approaches apply in presence of high supply voltages, when transistors

On-line Techniques to Adjust and Optimize Checkpointing Frequency

Due to increased susceptibility to soft errors in recent semiconductor technologies, techniques for detecting and recovering from errors are required. Roll-back Recovery with Checkpointing (RRC) is one well known technique that copes with soft errors by taking and storing checkpoints during execution of a job. Employing this technique, increases the average execution time (AET), i.e. the expected

Brain Talk : discourse with and in the brain : papers from the first Birgit Rausing Language Program Conference in Linguistics, Lund, June 2008

Brain Talk had as its theme, different aspects of language processing in the brain. The contributions focussed on the importance of context for the neurocognitive processing of language and speech in various communicative situations. The present volume, the first in the Birgit Rausing Language program conference series, contains papers from the Brain talk conference. They have been grouped in to

Serendipitous noise reduction in inductively degenerated CMOS RF LNAs

The design of radio-frequency inductively-degenerated CMOS low-noise-amplifiers does not follow the guidelines for minimum noise figure. Nonetheless, state-of-the-art implementations achieve noise figure values very close to the theoretical minimum. In this brief contribution, we point out that this is due to the effect of the parasitic overlap capacitances in the MOS device acting as transconduct

Rhythm Workshop

A conference poster presentation about how musicians develop their rhythmic skills. By practicing different kinds of rhythmic phrases such as odd grouping, odd metres, combined metres and metric modulations they can strengthen their rhythmic sense and expand their rhythmic freedom.

Att så vidare, 2007: Certec fyller tjugo

Att Certec fyller 20 ... firar vi genom att i bild och text ge bort en tankebok med 20 viktiga tankespråk/kortrubriker från de här åren. De får sammanfatta och komplettera avhandlingar och rapporter, löpsedlar och broschyrer, föreläsningar och verksamh

Magic, Health and the Mediation of the Body’s Geography.

This chapter examines some of the ways in which spas strive to offer their patrons a series of mass produced experiences that are framed in terms of personal wellness and serenity. In order to do this, the text begins by briefly examining the manner in which spas are organised as conceived spaces in their own promotional material. In the process, this material is placed in a historic context and i
