Obesity is one of today's most serious and amplified public health problems. Surprisingly, obesity constituted a health problem through the Byzantine Empire (3rd to 15th century AD) as well; the extent of the problem was then very much alike to that one seen in modem industrialized and developing countries of today. In this report we perform an historical throwback in Byzantine years in order t...

In this paper, we propose a preamble structure and appropriate acquisition algorithms for the uplink cable modem. The proposed preamble consists of a serial concatenation of identical constant amplitude zero autocorrelation (CAZAC) sequences. The proposed preamble is used for the frame detection, coarse symbol timing and carrier frequency recovery for the uplink cable modem compliant to data-ov...

This memo is to document a simple experiment. The experiment showed that in the case of a TCP receiver behind a 9600 bps modem link at the edge of a fast Internet where there are only 3 buffers before the modem (and the fourth packet of a four-packet start will surely be dropped), no significant degradation in performance is experienced by a TCP sending with a four-packet start when compared wi...

An anticommons problem arises when there exist multiple rights to exclude. In a lengthy law review paper, Michael A. Heller has examined "The Tragedy of the Anticommons," especially in regard to disappointing experiences with efforts to shift from socialist to market institutions in Russia. In an early footnote, Heller suggests that a formal economic model of the anticommons has not been develo...

In this paper we investigate the performance of common capture models in terms of the fairness properties they reflect across contenting hidden connections. We propose a new capture model, Message Retraining, as a means of providing an accurate description of experimental data. Using two fairness indices we undertake a quantitative study of the accuracy with which each capture model is able to ...

Dr. Bebbington is Senior Lecturer in History at the University of Stirling, Scotland. This article is the second in a series of three entitled 'Evangelical Christianity and Western Culture Since the Eighteenth Century' and was presented by the author in the Staley Lectures at Regent College in April1989. (The first lecture in the series was published in the December 1989 issue of Crux.) The lec...

Text telephone devices are text-based terminals that allow the users to communicate by text via fixed-line telephone networks. Since cellular phone systems are sometime subject to severe radio channel impairments and the modem signals of these text telephones are therefore not always transmitted reliably, the Federal Communications Commission (FCC) has required a solution to guarantee a reliabl...

The paper presents the advantages of using a single one-phase PLC (Power Line Communications) modem for last-mile communications over the three-phase LV network, which is dedicated to supply road and street Smart Lighting system. The main benefits of the proposed solutions are more reliable traffic concentrators and lower the cost of their construction. Using analytical method or based on the r...
