Introduction. In educational centers, evaluation of educational activities of teachers is done in different ways. One of the most common ways » nearly in all important universities « is student Evaluation of teaching (SET), which is done by questionnaires. Scientific evidences have showed that in spite of frequent usage of this kind of evaluation, opinions of students about teacher’s performa...

Priority queues with parallel access are an attractive data structure for applications like prioritized online scheduling, discrete event simulation, or branchand-bound. However, a classical priority queue constitutes a severe bottleneck in this context, leading to very small throughput. Hence, there has been significant interest in concurrent priority queues with a somewhat relaxed semantics w...

Computer networking technologies support high−speed transmission of information and services for multimedia applications that include voice, video and data traffic in a single access path. One of these technologies is Asynchronous Transfer Mode (ATM), which is a switching technology for information processing over the network and is the choice of Integrated Services Digital Networks (B−ISDN). A...

We describe a scalable priority queue manager that implements deadline-ordered service disciplines in an output-buffered ATM switch, which can be used as a switching node in high-speed packet switched networks to provide quality of service (QoS) guarantees. The priority queue manager can handle a range of priority levels from to , a buffer size of 64K ATM cells, and 16 input links at 2.5 Gb/s. ...

The increasing usage of information technology in military affairs raises the need for robust high capacity radio networks that will be used to provide several different types of services, such as group calls and situation awareness services. As all services have specific demands on packet delays and packet losses in order to be fully functional, there is a need for a qualityof-service (QoS) me...

We address the control plane architecture of how to provide advance quality of service (QoS) in optical burst switching networks based on dynamic wavelength assignment. Unlike existing QoS guaranteeing scheme, such as buffer-based and offset-time based scheme, our proposed dynamic virtual lambda partitioning (DVLP) scheme does not mandate any buffer or extra offset time, but can achieve better ...
