We consider the question of the capacity of the deletion channel when multiple copies of the codeword are sent independently through the channel. This type of coding problem is straightforward for standard erasure and error channels, but is more challenging in the deletion channel setting. Our results show that when the same codeword is sent k times through the channel, each time with independent...
This paper presents an improved dual second-order generalized integrator phase-locked loop (DSOGI-PLL) for three-phase systems, for dealing with the non-ideal three-phase grid voltages (e.g. unbalance, harmonics, frequency variation, magnitude variation, etc.) and rejecting the error caused by the DC offset introduced by signal conditioning and A/D conversion in practice, the SOGI used in the proposed...
This paper analyzes the interoperability issues of the information exchange among essential software applications that enable University electronic services. The analysis of the existing standards shows that there is no fully defined compatibility for these software solutions, which motivated us to conduct a research in order to detect and describe the interoperability challenges of creating a fully...
A fault-tolerant version of Open Message Passing Interface (Open MPI), based on the draft User Level Failure Mitigation (ULFM) proposal of the MPI Forum's Fault Tolerance Working Group, is used to create fault-tolerant applications. This allows applications and libraries to design their own recovery methods and control them at the user level. However, only a limited amount of research work on user...
Over past few years, there has been a huge advancement in terms of Learning Management System (LMS) and online education. Behind this growth, the major reasons are the availability of open source LMS and their ease of customization. This paper proposes some new features for these pre-existing LMS, especially Moodle, such that the same LMS could also function as College / University Management System...
Studies in social science and social computing have revealed that group dynamics plays an important role in group performance. Face-to-face interaction among group members has been regarded as one of the major determinants of performance in various business fields. However, the relationship between inter-child interaction in the school environment and their scholastic performance is unknown. An experiment...
In computing, Inter-process communication (IPC) is a set of methods for the exchange of data among multiple threads in one or more processes. Operating system works as an inter process synchronization manager (IPSM). In the present paper agent based inter process synchronization manager is described and its performance is compared with other non agent based IPSM on different operating systems.
