Although ‘Halcyon’ means serene environment which pervasive computing aims at, we have tried to present a different interpretation of this word. Through our approach, we look at it in context of achieving future ‘calm technology’. The paper gives a general overview of the state of pervasive computing today, proposes the ‘HALCYON Model’ and outlines the ‘social’ challenges faced by system design...

Female Petrosaurus mearnsi develop orange throat coloration when gravid. This coloration was induced in the nonbreeding season (late fall) by exogenous progesterone delivered by subcutaneous implantation in Silastic capsules or intramuscular injection. Color change was first apparent after five days of administration. The time course of brightening was similar for the two methods. Color change ...

ABSTRACT Objective: to assess salivary cortisol concentrations in hematology/oncology nurses on working days and off. Methods: a cross-sectional study carried out with 28 from university hospital. A sociodemographic, employment health profile questionnaire was applied. For saliva collection, Salivette® tubes were used. Descriptive analytical analysis Results: there no significant difference bet...

A number of conventional hypotheses relative to the Moon and the terrestrial planets deserve both questioning and unconventional thought based on the profound advances in planetary research in recent years. For example, elemental and isotopic data on the lower mantle of the Moon suggest that lunar origin by Giant Impact is unlikely. The apparent existence of a relatively undifferentiated lunar ...

The superiority of Africanized over European honey bees in tropical and subtropical regions of the New World is both well documented and poorly understood. As part of an effort to try to understand the process by which the displacement of European bees occurred, we examined the ability of these two types of bees and of hybrids between the two to convert natural and artificial diets into usable ...

[1] Cohen et al. [2000] recently confirmed the hypothesis that the Moon was resurfaced by an intense period of impact cratering 3.9 Ga ago and, by inference, that the Earth also sustained bombardment. Analyses of lunar impact melts indicate that at least one of the projectiles that hit the Moon was a differentiated iron-rich core, implying the bombardment was caused by asteroids. Meteorite anal...

We applied a variety of parametric and non-parametric machine learning models to predict the probability distribution of rainfall based on 1M training examples over a single year across several U.S. states. Our top performing model based on a squared loss objective was a cross-validated parametric k-nearest-neighbor predictor that took about six days to compute, and was competitive in a world-w...

In this paper we present the Cataclysm server platform for handling extreme overloads in hosted Internet applications. The primary contribution of our work is to develop a low overhead, highly scalable admission control technique for Internet applications. Cataclysm provides several desirable features, such as guarantees on response time by conducting accurate size-based admission control, reve...
