Over recent years, wireless communication systems have been experiencing a dramatic and continuous growth in the number of subscribers, thus placing extra demands on system capacity. At the same time, keeping Quality of Service (QoS) at an acceptable level is a critical concern …
Early breast cancer in women is best identified through high quality mammographic screening. This is achieved by well trained health professionals and appropriate imaging. Traditionally this has used X-ray film but is rapidly changing to utilise digital imaging with the resultan…
Recent research has indicated that although security systems are developing, illegal intrusion to computers is on the rise. The research conducted here illustrates that improving intrusion detection and prevention methods is fundamental for improving the overall security of syst…
This thesis is a study of multiple access schemes for satellite land mobile systems that provide a domestic or regional service to a large number of small terminals. Three orbit options are studied, namely the geostationary, elliptical (Molniya) and inclined circular orbits. The…
Mobile computing is becoming increasingly important, due to the rise in the number of portable computers and the desire to have continuous network connectivity to the Internet, irrespective of the physical location of the node. We have also seen a steady growth of the market for…
Project performance relies upon effective project management. Indeed, project management has been recognized as an important means for making changes in the organisation. Efficiency in project management, obviously, enhances the probability of project success, which consequently…
Large, complex system development projects take several years to execute. Such projects involve hundreds of engineers who develop thousands of parts and millions of lines of code. During the course of a project, many design decisions often need to be changed due to the emergence…
Pipeline operators continuously seek to improve reliability, safety and reduce corrosion and maintenance costs. Cathodic protection (CP) systems is a secondary external corrosion-prevention mechanism for underground pipelines. Two types of CP exist, namely, sacrificial anode CP …
In smart manufacturing systems, production scheduling, maintenance decision-making, and process monitoring are three key, closely interconnected components, which play significant roles in the system performance, quality control, and overall cost. Due to the rapid advancement of…
A aplicação de métodos numéricos apresenta-se como uma ferramenta que permite, não só reduzir o impacto ambiental e consumo de energia, como também tornar a otimização estrutural mais eficiente. Pode ser aplicado em várias indústrias, como a automóvel e aeronáutica, e contribuir…
Phylogenetics, the reconstruction of evolutionary relationships between species, underpins evolutionary biology. These relationships are most often inferred from either or both morphology and molecules, but molecular data are often preferred because of the objective atomization …
The First World War marked the end of the era of empires, followed by postwar accords which divided up territory into newly formed states. As a result of this new order, numerous ethnic groups found themselves under new regimes with new set of rolls. The research in hand seek to…
One vital question led to this research study: is there a relationship between emotional intelligence and employee's performance self-rating? Several researchers have constructed theoretical frameworks to better understand emotional intelligence. Theoretical and empirical eviden…
This study examines the influence of the Financial Crisis of 2008 on European firms’ earnings management behavior. For this purpose, the period from 2005 to 2012 and a sample of 16 different European countries were considered and divided into three periods to examine whether man…
Empirical studies have revealed that many financial asset returns are characterized by an asymmetric behavior of the volatility. Aside from asymmetry, another important stylized fact about the volatility is its long memory effect. Given that the computation of the volatility is …
Esta investigación examina la evaluación de desempeño desde el punto de vista de los maestros, los directores y las organizaciones magisteriales en el contexto educativo de Puerto Rico, ya que el proceso de evaluación de desempeño requiere de líderes que posean las competencias …
This study explored the current status of adjunct faculty teaching-performance evaluation at public community colleges across the United States and how the results of evaluations were used to make decisions pertaining to professional development, employment and recognizing excel…
Although the use of daylight has an important role in educational spaces, uncontrolled use of daylight can lead to some undesirable situations for occupants. It is generally accepted that recommended illuminance values change between 300 lux and 2000 lux in educational spaces. H…
