The benefits of e-government initiatives empowered by the information and communication technologies, are acknowledged widely with assessment criteria published by the United Nations regularly over the last 15 years. One of the reasons that United Nations has taken such assessment into agenda is the apparent advantages of such initiatives over the citizen, society and government. In parallel literature review and current status of Middle East countries, these issues are investigated with examples: Internet users, awareness and training, culture, intention to use e-government applications of the citizens, portal and interoperability. It is noted that assessment of human capital indices for these countries should be read carefully while considering these topics. The findings reveal the impact of human capital index on evaluating egovernment performance; geographical area and population also affect the adoption of e-government. For this, follow-up work is suggested to investigate the level of information and communication technology and computer literacy along with these factors in the region. This research has limitations which include the sources of information, exclusive economic and legal issues and a number of measurement methods.
Energy efficiency in wireless sensor networks
(2015) Hussein, Mohammed
Wireless Sensor Networks (WSNs) are consists of small sensor nodes with limited battery power, processing and memory units. There are two important features in WSNs. The first one is the infrastructure-less and second one is the self-organization. These properties make sensors convenient choice for several applications. When we try to investigate algorithms and protocols for wireless sensor networks we must study the features and constraints of WSNs. However, battery recharge is not possible or extremely challenging for sensor nodes. The main aspect in designing wireless sensor networks algorithms and protocols is ensuring energy efficiency and prolong the sensor network lifetime. Farther more the sensor node position within the set of deployed nodes decides which tasks have to be carried out and how many communication paths involve each individual sensor node. On the other hand the sensor networks in more obstructed environments, the path loss exponent value is vary. The high path loss exponent value increases unbalance energy depletion between nodes. In this thesis we investigated two node deployment strategies which are uniform and non-uniform (normal distribution) sensor node deployments with various path loss exponent values. We used a Linear Programming (LP) framework to analyze the effect of node deployment model on the network lifetime. Also we studied the effect of path loss on the wireless sensor network lifetime. Our results showed that by normal node deployment, energy balance can be improved up to certain level. However, increasing path loss exponent in normal node deployment may lead to decrease in improvement ratio.
Investigation of human capital index measurement in the middle east countries
(2015) Hussein, Mohammed
The field of e-government has become one of the most developed and most important applications of Information and Communication Technology (ICT) around the world in recent years due to its positive impact on citizens, government and society because it refers to delivering government public services using ICT. The e-readiness assessment and e-government performance measurements for a country rely on the availability of necessary infrastructure, online services and readiness of a community to use e-government applications. This study focuses how the Human Capital Index (HCI) fits into e-government performance measurements in Middle Eastern countries. In parallel to the background, literature review and analysis data of Middle East countries in HCI, investigation in HCI for Middle East countries and potential issues that effect on HCI in those countries are done. Also, the impact of HCI proportion on the e-government performance is addressed. The findings reveal impact of HCI on evaluating the e-government performance; geographical area and population also affect the adoption of e-government. Additionally, the level of ICT and computer literacy is relatively poor in Middle Eastern countries. This research has limitations which include the sources of information, exclusive economic and legal issues and a limited number of measurement methods. Finally, the research opens HCI's weight into discussion in the evaluation of e-government performance although it is clear that whenever HCI increases in a country, it leads to an increase in e-government performance with the investigated measurement methods
