We propose and analyze a scalable and efficient cluster-based group key management protocol for secure group communications in mobile ad hoc networks. For scalability and dynamic reconfigurability; we take a cluster-based approach by which group members are broken in to cluster-based subgroups and leaders in subgroups securely communicate with each other to agree on a group key in response to membership change and member mobility events. We show that secrecy requirement for group communication is satisfied. Further, there exists an optimal clus ....etc

This project is aimed at developing a scheduler for group meetings. This is a web-based tool. Any user can call for a meeting and send the detailed co-ordinates of the meeting (location, date, time etc) to all invitees. This is useful for a small office, school or a department or for that matter any group who is interested to organise it effectively. Facility to book room and editing booked room are also available. ....etc

Abstract—Given a data point set , a query point set , and an integer , the Group Nearest Group (GNG) query finds a subset ( ) of points from such that the total distance from all points in to the nearest point in is not greater than any other subset ( ) of points in . GNG query is a partition-based clustering problem which can be found in many real applications and is NP-hard. In this paper, Exhaustive Hierarchical Combination (EHC) algorithm and Subset Hierarchial Refinement (SHR) algorithm are developed for GNG query pr ....etc

Definition
The term group dynamics implies that individual behaviours may differ depending on individuals' current or prospective connections to a sociological group. Group dynamics is the field of study within the social sciences that focuses on the nature of groups.

Urges to belong or to identify may make for distinctly different attitudes (recognized or unrecognized), and the influence of a group may rapidly become strong, influencing or overwhelming individual proclivities and actions. The group dynamics may also include changes in beha ....etc

Fundamental Idea: Robot Pose
2D world (floor plan)
3 DOF
Major Issues with Autonomy
Movement
Inaccuracy


How do we Solve Localization? Represent beliefs as a probability density
Markov assumption
Pose distribution at time t conditioned on:
pose dist. at time t-1
movement at time t-1
sensor readings at time t
Discretize the density by
sampling


Localization Foundation
At every time step t:
UPDATE each sampleâ„¢s new location based on movement

FACTS is a concept introduced by Electric Power Research Institute (EPRI), U.S.A.It is actually a group of advanced transmission technologies that rely on high speed, solid-state electronics, rather than electromechanical devices.

By this concept, the apparent impedance of a transmission line is controlled according to certain algorithm. Thus the power system operation is made more reliable, controllable and efficient. The FACTS system is a promising method, which can be implemented into the system for enhancing system stability by damping ....etc
