Technology evolution in the field of Unmanned Aircraft Systems (UAS) will affect the Air Traffic Management (ATM) performance regarding to new military and civil applications. UAS, as new airspace users, will represent new challenges and opportunities to design the ATM system of the future. The goal of this future ATM network is to keep intact (or improve) the network in terms of security, safe...

We study a variety of image deblocking algorithms for improving quality of visual signals degraded by blocking artifacts from compression. The image improvements afforded by these algorithms is measured using the PSNR, PSNR-B, and SSIM. Rather than relying on PSNR, which correlates poorly with subjective judgment, we propose a new Deblocking quality index that is sensitive to blocking artifacts...

In this essay, I present a framework for assessing conflict resolution programs and indicate how practitioners or educators can do research which will enable them to productively reflect on their practice. There are many kinds ofresearch, all ofwhich have merit. They have different purposes and often require varying types of skills. There is a tendency among both researchers and practitioners t...

Now a days, cloud computing has been an emerging concept in the IT industry. Cloud computing is not a new technology but is a new way of using or delivering the resources. It also enhances the efficiency of computation by providing the facility of centralized database, memory processing and on demand network access. This paper examines the different categories of risks which can be controlled o...

Spatial data, i.e., data related to objects that occupy space, are continuosly being collected for various applications ranging from remote sensing, geographical information systems (GIS) to computer cartography and environmental assesment and planing. The volume of data collected is so huge that it has become humanely impossible to do any intelligent data analysis. Even though very few methods...

Nail changes are present in about 50% of psoriasis patients and tend to be refractory to conventional treatments. Pulsed dye laser has emerged as an alternative therapy. Our aim is to evaluate the efficacy of pulsed dye laser in nail psoriasis and the impact of treatment on quality of life. Fourteen patients were treated in monthly sessions for three months. The outcome assesment was made by th...
