1. Research on Wireless Communication Expectation in "IEEE Wireless Communications.

In this seminar discussion, two research topics are discussed in the area of IEEE wireless communication.

The first topic focuses main two motivations -- D2D network and proposed (FlashLinQ)

The FlashLinQ Enables device to directly sense surrounding and direct communication with each other.

The second topic emphasized about High performance sensitive application such as mobile TV, video calling, etc. for 4G wireless system and others which includes--

--End-to-End (E2E) QoS and service assurance support in WiMAX and LTE networks
--Quality of audio and video content at the source (depends on codec)
--QoS of E2E network source to user terminal (bandwidth, delay, jitter, and packet loss)
--User terminal (performance of equipment)
--Human perception (mean opinion score)

The QoS Support in 4G Networks is discussed in details, including the features of VOIP, IPTV and Video streaming.

The 4 G Wireless networks are projected to offer high raw data rates in the down-link as well as in the up-link directions. These networks are compelled by the need to support the rich optical hypermedia services and applications. 4G wireless networks also provision global roaming and multiple classes of services and the requirements across dissimilar wireless systems. Agility management became an important issue since when the mobile devices are become more and more popular. This discussion gives an impression of agility management in mobile network which embraces the concept of position management and hand-off management

Some future research areas are suggested, which includes Coexistence heterogeneous 4G wireless network, Multi-BS MIMO, Vehicular management using 4G broadband and Green communications.

2. Age-related differences in white matter microstructure Region-specific patterns of diffusivity.

This discussion highlighted about the functional and structural aspects of human brain across various age groups.

The regional specificity of the microstructural alterations in aging cannot be properly addressed through histological studies, so to solve the problem; one of the possible solutions is diffusion tensor imaging (DTI), which combines some of the benefits of both histological and volumetric approaches in studying White Matter.

The participants of various age groups are taken by ensuring that They have no history of psychiatric or neurological disease previously. The DTI data are analyzed in details to identify the possible patterns and its respective disease symptoms.
The FSL 4.1 Diffusion Toolbox is mainly used to analyze the DTI data.

3. A Local Voronoi Diagram-Based Approximate Algorithm for Minimum Disc Cover Problem.

This seminar discussion mainly explains the power conservation issue of the wireless sensor network using voronoi diagram.

Here the discussion starts with the introductory concept of sensor , minimal cover set problems , design and analysis of minimal disk cover set algorithm with the implementation of voronoi graphs and it's time complexity estimations . Here the localization of voronoi diagram always refers to the nearest neighboring sensor nodes, which are to be properly structured with some approximation algorithms so as to minimize the power consumptions . As the sensors are battery powered , so its energy must be effectively preserved for longer functioning .
