GIS and spatial analysis have enjoyed a long and productive relationship over the past decades. GIS has been seen as the key to implementing methods of spatial analysis, making them more accessible to a broader range of users, and hopefully more widely used in making effective decisions and in supporting scientific research. It has been ...

The FACTSs (Flexible AC Transmission Systems) devices have all the capabilities to provide fast control of active and reactive power through a transmission line. The UPFC (Unified PowerFlow Controller) is a member of the FACTS family with very unique features. UPFC can control active and/or reactive power simultaneously or independently. This paper establishes the improved ...

The simulation model of DDPMSG 10KW grid connected are developed using Matlab 2013(a) and fast simulator. In addition to its SVPWM technique has been applied for 10KW grid connected model. Space vector pulse width modulation has been used for obtaining the output voltage with less distortion. An interface has also been developed between fast and ...

In this paper, the authors presented a robust PID controller design for time delay system. Utilizing the gain-phase margin tester method, a specification-oriented parameter region in the parameter plane that characterizes all admissible controller coefficients sets can be obtained. The PID controller gains are then directly selected from the parameter region. And the designed controller ...

Online social networks, such as Facebook, Twitter, Yahoo and Google+ are utilized by many people. These networks allow users to publish details about themselves and to connect to their friends. Some of the information revealed inside these networks is meant to be private or public. Yet it is possible to use learning algorithms on released ...

In this paper, the authors introduce a Test Pattern Generator (TPG) in order to use in Built-In Self-Test (BIST). MSIC TPG generates Multiple Single Input Change (MSIC) vectors in a pattern, i.e., each vector applied to a scan chain is an SIC vector. With the help of reconfigurable Johnson counter and a scalable SIC counter ...

In the last years, a major transition from analog to digital modulation techniques has occurred and it can be seen in all areas of wireless communication, satellite and cellular systems. This paper give the brief description of digital communication system. Digital communication is more reliable, secure and efficient than that of analog communication. In digital ...

In mobile ad hoc network nodes dynamically forms networks, there is no any central infrastructure, and thus routing becomes a very important issue. Routing protocols used in Mobile Ad hoc NETworks (MANET) must adapt to frequent or continual changes of topology, while simultaneously limiting the impact of following these changes on wireless resources. This paper ...

DoS attacks today are part of every Internet user’s life. As the Internet is growing – so is the vulnerability of the network. Companies now days are spending huge amount of money to protect their sensitive data from different attacks that they face. DoS or Denial of Service attacks are one of such kind of ...

In this paper, the authors deal with depth maps extraction from multi-view video. Contrary to standard stereo matching-based approaches, de-PTH maps are computed here using optical flow estimations between consecutive views. They compare their approach with the one proposed in the Depth Estimation Reference Software (DERS) for normalization purposes in the ISO-MPEG 3DV group. Experiments ...
