In the study 'we aim to address two important topics: Information and Communication Technologies (ICT) and E-Learning with study and analysis in the Northern Technical University (NUT) as key factors for the success of educational organizations in general and technical higher education institutions in particular. as well as the conviction of these educational institutions that the availability of...
With the increased use of ICT in different areas of contemporary life, the widespread access to the Internet, and the use of social media, individuals and organisations face constant threats and challenges resulting from the bad consequences of cybercrimes. Research shows that the incidence of cybercrime is increasing. In response to these threats and challenges, government and law enforcement agencies...
In this paper, three modulation strategies based on a multicarrier level shifted PWM and third harmonic injected reference have been implemented; the aim of this paper is to compare these three strategies to know their effect on the output voltage quality of the inverter. The three modulation strategies are: Third Harmonic Injected reference In Phase Disposition (THI-IPD), Third Harmonic Injected...
Internet of Things (IoT) is a concept of communications between multiple devices equipped with sensors and actuators for the purpose of convenience and economic benefits. In connection with the rapid development of IoT concept it becomes necessary to use those or other instruments for the control and management of IoT. Considered scenario is based on the interaction between the central element (smart...
The exponential growth of devices connected to the Internet flogged need to improve methods of network management and recently has become one of the most difficult tasks. As a result of the rapid increase in devices connected to the Internet will increase a huge amount of traffic of today's networks. The ideology of software-defined networking will significantly automate and facilitate network management...
In this paper a new time dependent pricing scheme is proposed for revenue management in mobile calls. The proposed scheme considers many essential parameters that affect pricing such as time-of-day seasonality, weekday/weekend seasonality and price demand elasticity for call arrivals and call duration. In this model, each day is partitioned into a number of periods; each period has a price according...
Multilevel inverter has become attractive in the power industries and it can be applied in many applications especially in renewable energy systems and improvement of the power quality. On the other hand, the technique used to generate the required switching pulses plays an important role to improve the inverter characteristics. The paper presents an assessment of three different types of control...
In this paper, a five-phase induction motor drive system supplied using a PWM Voltage source Inverter (VSI) with output LC filter is discussed. The design and performance of drive system with LC filter connected at the output terminals of the PWM inverter is elaborated. The purpose of the filter is to eliminate both high-frequency harmonics of the voltage and current waveforms from the five-phase...
