Received (received date) Revised (revised date) Communicated by Editor's name ABSTRACT Gang scheduling has been widely used as a practical solution to the dynamic parallel job scheduling problem. To overcome some of the limitations of traditional Gang scheduling algorithms, Concurrent Gang is proposed as a class of scheduling policies which allows the exible and simultaneous scheduling of multi...

Chemical and biological weapons can be used during conflicts and by terrorists to injure or kill humans and animals. Chemical weapons contain toxic chemicals and biological weapons contain pathogenic organisms. With proper protective equipments and training, the lethal effects of chemical and biological warfare agents can be minimised. First aid kit is available that contain detection, decontam...

We deene the bounds of two gang service algorithms, namely time balanced and instruction balanced, using interactivity and throughput based metrics. The work-load is composed of V-RAM jobs, and the architectural model chosen is LogP. We also analyze the eeect of workload and space sharing strategies on the bounds found. The following results are demonstrated: when inter-activity is considered, ...

The goal of this paper is to determine how e ciently we can implement an adequate parallel programming environment on a workstation cluster without modifying the existing operating system. We have implemented a runtime environment for parallel programs and gang-scheduling on a workstation cluster. In this paper, we report the techniques used to implement gang-scheduling on a workstation cluster...

Gang youth are at an increased likelihood of participating in unsafe sexual behaviors and at an elevated risk of exposure to sexually transmitted infection (STIs), including HIV. This manuscript presents quantitative and qualitative data on sexual behaviors among a sample of predominately heterosexual, male gang youth aged 16 to 25 years interviewed in Los Angeles between 2006 and 2007 (n = 60)...

OBJECTIVE To examine the association between gang involvement and female adolescents' health. METHODS African American adolescent females (N = 522) completed a survey that assessed their history of gang involvement and health behaviors and provided specimens that were analyzed for marijuana use and sexually transmitted diseases. RESULTS In logistic regression analyses, adolescents with a hi...

In the context of hybrid warfare, an urgent question arises as to adequacy responding its challenges. Ukraine, EU countries and NATO are facing new threats, which require democracies make changes in military political activities, find forms methods ensuring national security. Hybrid warfare a form undeclared war is conducted with integrated use non-military instruments (economic, political, inf...

Many urban environments have criminal gangs competing for control of available resources and gang territories. Research in criminology has linked the effect of these gang territories on criminal activity by criminal gangs. However, a great deal of a given criminal group’s activity occurs beyond the boundaries of that gang’s known territory but within a region we term a gang’s criminal sphere of...

Gang affiliates have joined the masses who use social media to share thoughts and actions publicly. Interestingly, they use this public medium to express recent illegal actions, to intimidate others, and to share outrageous images and statements. Agencies able to unearth these profiles may thus be able to anticipate, stop, or hasten the investigation of gang-related crimes. This paper investiga...
