Optimized and integrated alignment system for functional proton radiosurgery

In this thesis work, a system for proton beam alignment was studied and optimized in many of its functional areas. The resulting system was named Positioning Alignment Control System (PACS). The PACS system is an integrated and efficient system as a result of the work done on it in the course of this thesis work

The causal relationship between SME sustainability and banks’ risk

This study aims to examine the influence of banks’ credit to SMEs on non-performing loans. Many studies find that access to financial sources has become an obstacle to the growth and sustainability of SMEs. This study uses theoretical and empirical approaches to support the study’s hypothesis. Data are presented for 15 banks in Palestine, covering the period 2006 to 2016.The study uses empirical techniques regarding to examine the relationship between the variables. Evidence shows that encouraging banks to lend more money to SMEs through the use of a guarantee fund could decrease their risk. Thus, enhancing credit to SMEs could improve the growth and sustainability of these firms. The study recommending policymakers and bank’s managers could develop their strategies according to SME’s needing. Therefore, enhancing the growth in these firms and reducing the bank’s risk. Furthermore, adopting the guarantee funds in developing countries could decrease the bank’s risk, thus lending more to SME. The value of this paper comes from the importance of SME in the economic growth and development sustainability. Therefore, there is a need to convince banks to enhance SME credit through a guarantee fund and that extending this type of credit would positively influence banks’activities

Energy, Trade, Urbanization and Environmental Degradation Nexus in Sri Lanka: Bounds Testing Approach

This study examines the nexus between energy, trade, urbanization and environmental degradation in Sri Lanka. The time series data has been checked for unit root problem along with unknown structural break. The bounds testing approach confirms the long-term relationship among carbon emissions, energy consumption, income, trade openness, and urbanization in the presence of structural break. The results of the study do not confirm the presence of the EKC (Environmental Kuznets Curve) hypothesis in Sri Lanka. This study finds that energy consumption leads to carbon emissions in both the long term and the short term. Trade openness is degrading environmental quality, as trade is responsible for the accumulation of carbon emissions in the atmosphere. The results of the study confirm that urbanization has been found to have significant and negative effect on carbon emissions. The study finds that the model is in equilibrium and the model will return to equilibrium from any external shock in less than two years. Policy measures are recommended for sustainable environment of the island
