A transfer line design problem is considered. Transfer lines are sequences of workstations equipped with processing modules called blocks each of which performs specific operations. These lines are used for mass production of one type of product and thus execute repetitively a given set of operations. The machine parts move along the stations in the same direction. An identical cost is associat...

The study examined the effect of EI on performance police officers at Gulu Central Police station. Specifically, addressed: self-awareness and self-regulation in recruitment selection officers, motivation social skills task assignment empathy training officers. adopted a cross sectional descriptive design with only quantitative approaches. used sample size 155 respondents. items/constructs this...

Given the scarcity of energy in wireless sensor networks (WSNs), innetwork data processing by distributed, cooperating services is often used to reduce the amount of information that has to be routed to the base station and thereby to reduce communication and energy consumption. However, to minimize the amount of communication between services and their requesters, the locations of services in ...

We investigate a hybrid noncooperative game motivated by the practical problem of joint power control and base station (BS) assignment in code division multiple access (CDMA) wireless data networks. We model the integrated power control and BS assignment problem such that each mobile user’s action space includes not only the transmission power level but also the respective BS choice. Users are ...

Secure communication is a promising technology for wireless networks because it ensures secure transmission of information. In this paper, we investigate the joint subcarrier (SC) assignment and power allocation problem for nonorthogonal multiple access (NOMA) amplify-and-forward twoway relay wireless networks, in the presence of eavesdroppers. By exploiting cooperative jamming (CJ) to enhance ...

The virtualization of Radio Access Networks (RANs) has been proposed as one of the important use cases of Network Function Virtualization (NFV). In Virtualized Radio Access Networks (VRANs), some functions from a Base Station (BS), such as those which make up the Base Band Unit (BBU), may be implemented in a shared infrastructure located at either a data center or distributed in network nodes. ...

Recent demand for wireless communication continues to grow rapidly as a result of the increasing number of users, the emergence of new user requirements, and the trend to new access technologies. At the same time, the electromagnetic spectrum or frequencies allocated for this purpose are still limited. This makes solving the frequency assignment problem more and more critical. In this paper, a ...
