Internet have become so indispensible in today's world. It is being used for varied purposes from using it as a source of information to use it for effective communication and sharing resources around the world. People today favor more for the communication oriented web portals like the chatting services and social networking portals. This has been evidently proved by the highly famous social networking projects of the world like orkut, facebook and Hi5. The number of users for these social networking sites has been on a constant increase. They serve as an effective communication channel to chat with people around the world irrespective of distances or any other external factors. They give a platform to make friends and form develop a social community effectively with ease. but there has not been an effective authenticated platform still for effective technical idea sharing in the world. There are several blogs which now favor technical discussions, but they are not very authenticated or secure enough to share innovations. There are also several community portals like IEEE and ACM, but they do not support active idea sharing like a chat or discussion forum as in social networking. Moreover they bore only highly complex technical research ideas and a novice in a field willing to enter may find it abstruse. so there is a severe lack in technical communication and there is a need for an effective platform for discussing and sharing technical innovations between students, industries and research peoples. Presently many students with many innovative ideas are not having an effective forum to present or discuss their novelties. Furthermore industries are struggling to allocate huge funds for training the students to the industrial standards with real time skills. This could be greatly reduced if students are given a platform to think innovate and guided to implement them they could develop these real time skills in their universities during their graduation studies, as th

An ad-hoc network comprises of mobile nodes that cooperate with each other using wireless connections to route both data and control packets within the network. They are characterized by the use of wireless links, dynamically changing topology, multi-hop connectivity and decentralized routing mechanism and decision-making. The performance of Ad-hoc On Demand vector (AODv) protocols has been modified by including the source route accumulation feature. As low transmission power of each ad-hoc node limits its communication range, the nodes must assist and trust each other in forwarding packets from one node to another. However, this implied trust relationship can be threatened by malicious nodes that may fabricate, modify or disrupt the orderly exchange of packets. security demands that all packets be authenticated before being used. A particularly hard problem is to provide efficient broadcast authentication, which is important mechanism for MaNet. In this paper, we propose a routing algorithm which adds a field in request packet which stores trust value indicating node trust on neighbour. based on level of trust factor, the routing information will be transmitted depending upon highest trust value among all. This not only saves the node's power by avoiding unnecessary transmitting control information but also in terms of bandwidth (channel utilization), which is very important in case of MaNet. The malicious node can attack on the control packet and misbehave in the *** malicious node, which may or may not be trusted node. In this paper, we use trusted path irrespective of shortest or longest path which can be used for communication in the network. We are able to calculate route trust value on the complete reply path which can be utilized by source node for next forthcoming communication in the network. © 2010 IEEE.

A study examining speech compensation in persons who stutter is presented. The underlying assumption is that if PWs are at the lower end of a speech motor skill continuum one should be able to find differences between PWs and PNs in tasks which tax their abilities to control their speech motor system. If delayed compensation is found in PNs with perfectly intact sensory-motor systems. Then one would expect that if PWs have speech motor skill limitations, they would compensate to a lesser degree and/or may take longer time to adapt to oral articulatory perturbations relative to PNs. Word and vowel duration measures provide an index of how task requirements relating to speech rate are implemented by PWs and PNs. The data also revealed that PWs may require additional time compared to PNs to adapt to perturbations.

Two-particle correlations in relative azimuthal angle (Δϕ) and pseudorapidity (Δη) are measured in sNN=5.02 Tev p+Pb collisions using the ATLAs detector at the LHC. The measurements are performed using approximately 1 μb−1 of data as a function of transverse momentum (pT) and the transverse energy (ΣETPb) summed over 3.1<η<4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2<|Δη|<5) “near-side” (Δϕ∼0) correlation that grows rapidly with increasing ΣETPb. A long-range “away-side” (Δϕ∼π) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small ΣETPb, is found to match the near-side correlation in magnitude, shape (in Δη and Δϕ) and ΣETPb dependence. The resultant Δϕ correlation is approximately symmetric about π/2, and is consistent with a dominant cos 2Δϕ modulation for all ΣETPb ranges and particle pT.

There are various approaches to achieve time synchronization in case of wireless sensor networks. Amongst them "sender to receiver" and "receiver to receiver" are the frequently used approaches for synchronizing time. both the methodology has some drawbacks with respect to number of message exchanged for synchronization. To overcome those drawbacks Hybrid approach was introduced. Hybrid approach is efficient with respect to number of message exchanged compared to both methodology. In this paper Hybrid Approach is improved, to reduce the message communication that is required to synchronize time between the nodes in sensor network. © 2010 springer-verlag berlin Heidelberg.

The local color cue based candidate boundary detection incorporating stationary Haar wavelet decomposition at various levels and thresholded proximity influence measures are used for detecting edges in color images in the proposed method. The non-homogeneous inter-tuples and non-uniform intra-tuple contributions of RGb tuples for conception of perceptual-edges are exploited in the edge detection method from candidate boundaries for color images. These edge detection results are presented here and qualitatively compared with those produced with leading image processing & desk-top-processing tools - Adobe Photoshop, Ms Photo Editor and ACD Photo Editor for images of different resolutions, types and characteristics. The method results, incorporating different levels of stationary Haar wavelet decompositions are also compared, analyzed and presented. The qualitative comparison of results of thinned edges is also presented. The method results outperform others detecting perceptually significant edges, proving its suitability for edge features extraction, object detection & identification. © 2010 IEEE.

The proposed novel method categorizes candidate boundaries into visually-prominent and non-prominent boundaries, considering local intensity cues of multiple color channels and pixel-prominence-values measured as a function of proximity-influence of other contours. The results of the method with and without incorporating a wavelet transform are compared for images of different characteristics, types and resolutions. The method has been exhaustively tested on textured, medical, natural, biometric and synthesized images for prominent boundaries detection. The method results are qualitatively compared with those of human segmented images of benchmark image-segmentation dataset. The results presented show suitability and compatibility of the method for detecting prominent boundaries in various images. These boundaries - forming regions, make the basis for object detection and identification. ©2010 IEEE.

Measurements of four-lepton (4ℓ, ℓ=e,μ) production cross sections at the Z resonance in pp collisions at the LHC with the ATLAs detector are presented. For dilepton and four-lepton invariant mass regions m(ℓ+ℓ(-)) > 5 Gev and 80v, the measured cross sections are 76 ± 18(stat) ± 4(syst) ± 1.4(lumi) fb and 107 ± 9(stat) ± 4(syst) ± 3.0(lumi) fb at sqrt[s] = 7 and 8 Tev, respectively. by subtracting the nonresonant 4ℓ production contributions and normalizing with Z → μ(+)μ(-) events, the branching fraction for the Z boson decay to 4ℓ is determined to be (3.20 ± 0.25(stat) ± 0.13(syst)) × 10(-6), consistent with the standard model prediction.
