The explosive growth of user data on the Internet has introduced significant security threats. In recent years, large data breaches and malicious content distribution (spam, malware) become prevalent. With the rapid adoption of mobile and wearable devices, user data now includes a wide range of personal mobile and physical data. It ranges from GPS location traces, to biometrics data, to user in...

Jobs that do not require all processors in the system can be packed together for gang scheduling. We examine accounting traces from several parallel computers to show that indeed many jobs have small sizes and can be packed together. We then formulate a number of such packing algorithms, and evaluate their eeectiveness using simulations based on our workload study. The results are that two algo...

for the characteristics of horizontal fractures in shallow low-permeability oil layers after hydraulic fracturing in multilayer reservoirs, horizontal fractures are taken equivalent to an elliptical cylinder with the reservoir thickness using the equivalent permeability model; then, upon the elliptic seepage theory, the seepage field which has led by a vertical well with horizontal fractures is...

The analysis of cantilever beams of small dimensions taking into the effect of fringing fields is studied and the parameters are estimated. Extracting the mechanical properties of MEMS devices has always been a challenge in terms of test time and test cost due to difficulties associated with accurate characterization of thin films. A technique for diagnosing the mechanical parameters of a canti...

This work considers the best way to handle a diverse mix of multi-threaded and single-threaded jobs running on a single Symmetric Parallel Processing system. The traditional approaches to this problem are free scheduling, gang scheduling, or space sharing. This paper examines a less common technique called dynamic space sharing. One approach to dynamic space sharing, Automatic Self Allocating T...

Belonging to a criminal gang often strongly influences members’ identities, particularly their self-perceptions and social roles. Entering or leaving may challenge understandings of the meaning structure lives threaten sense control. The aim this study was explore how members narrate these transitions whether such stages be seen as liminal passages. This article draws in particular on theory po...

Maxson (eds.), Youth Gangs in International Perspective: Tales from the Eurogang Program of Research, DOI 10.1007/978-1-4614-1659-3_6, © Springer Science+Business Media, LLC 2012 Identifying the infl uence of groups on human behavior is a central task of social scientists. For decades, researchers have sought to determine how groups affect individual behavior in various co...
