In this paper we look at how camera networks can be used in the healthcare industry for remote patient monitoring. This type of network would be installed in the home and have the ability to alert officials should an emergency arise. A network of this kind could be of benefit to many, and in particular to the growing number of elderly citizens by helping them to maintain their independent lifes...

Фоновая социальная напряженность общества может быть количественно оценена по различным статистическим индикаторам. Модели, прогнозирующие динамику социальной напряженности, успешно применяются для описания различных социальных процессов. Когда количество рассматриваемых групп мало, соответствующих индикаторов можно описать при помощи системы обыкновенных дифференциальных уравнений. При увеличе...

where Th is the threshold. The foreground image is composed of all foreground pixels. The threshold is computed with the help of the user, who is prompted to place ellipses on the mice that are visible in 7 randomly selected frames. Using this information, the optimal threshold Th for background subtraction is computed by minimizing a cost function that counts false alarms (the number of pixels...

This study reports a simple experiment using induced-value items to assess the accuracy of the Becker, DeGroot, Marschak (BDM) method (1964 Behavioral Science) for measuring preferences. Although the BDM mechanism is incentive compatible the data indicate that it can be empirically unreliable due to susceptibility to subject misconceptions about the game form. The resulting choices appear to re...

Effective data analysis ideally requires the analyst to have high expertise as well as high knowledge of the data. Even with such familiarity, manually pursuing all potential hypotheses and exploring all possible views is impractical. We present DataSite, a proactive visual analytics system where the burden of selecting and executing appropriate computations is shared by an automatic server-sid...

BACKGROUND Increasing socio-economic inequalities in health, within a country as well as internationally, give rise to a timely question: Are there any systematic differences between people from differing social backgrounds with regard to their attitude to seeking professional medical assistance when experiencing physical problems of varying kinds? MATERIAL AND METHOD The data material is tak...

This paper provides an empirical analysis of the impact of regime changes in the composition and patterns of recruitment of the Portuguese ministerial elite throughout the last 150 years. The ‘out-of-type’, violent nature of most regime transformations accounts for the purges in and the extensive replacements of the political personnel, namely of the uppermost officeholders. In the case of Cabi...

This article provides a brief history and background of workers' compensation programs for occupationally injured and ill workers in the United States. It presents the basic principle involved in workers' compensation and briefly discusses the disability benefits to which workers are generally entitled. It also discusses why there are settlements in this disability program and the availability ...

We propose a generative model for social networks, both undirected and directed, that takes into account two fundamental characteristics of the user: background (specifically, the real world groups to which the user belongs); and behavior (namely, the ways in which the user engages in surfing activity and occasionally adds links to other users encountered this way). Our experiments show that ne...
