Faster and more cost-efficient, crowdsourced delivery is needed to meet the growing customer demands of many industries, including online shopping, on-demand local delivery, transportation. The power stems from large number workers potentially available provide services reduce costs. It has been shown in social psychology literature that fairness key ensuring high worker participation. However,...

Recently, mobile computing has received much attention from database community. Sharing information among mobile users is one of the most challenging issues in mobile computing due to user mobility. Replication is a promising technique to this issue. However, adopting replication into mobile computing is a non-trivial task, since we are still facing other problems such as the lack in disk capac...

Since the strict separation of working spaces of humans and robots has experienced a softening due to recent robotics research achievements, close interaction of humans and robots comes rapidly into reach. In this context, physical human– robot interaction raises a number of questions regarding a desired intuitive robot behavior. The continuous bilateral information and energy exchange requires...

This paper addresses resource reclaiming in the con text of non preemptive priority list scheduling for hard real time systems Such scheduling is inherently suscep tible to multiprocessor timing anomalies We present low overhead run time stabilization methods for a gen eral tasking model that allows phantom tasks as a mech anism to model processor external events A family of scheduling algorith...

The discipline of economics is made up of a static body of theory that explores the efficiency of resource allocation at an instant of time and under the restrictive assumptions of frictionless markets. Recent research has explored the nature of the frictions by incorporating institutions, transaction costs, and political economy into economic analysis thereby providing the theory with a bridge...

The active surveillance of public and private sites is increasingly becoming a very important and critical issue. It is therefore, imperative to develop mobile surveillance systems to protect these sites. Modern surveillance systems encompass spatially distributed mobile and static sensors in order to provide effective monitoring of persistent and transient objects and events in a given Area Of...

Objectives: The role of cognitive process for postural control was shown in dual task studies. However, there was no definite evidence how verbal instructions influence the allocation of attention to postural control. This study determined whether young and elderly adult are able to deliberately control the resource allocation when performing a sensorimotor and cognitive task simultaneously and...
