Wireless Mesh Network is one of the b.dding tech.ologies in wireless networks. Routing in WMN is complicated and unpredictab.e than wired network, due to unstab.e link states and interference b.tween neighb.r routers. Since WMN is supporting hyb.id architecture, a primitive metric like hop count is not efficient to route the information in the network. The Expected Transmission count (ETX) is radio b.sed metric and it reveals the link conditions in the form of delay, loss of packets and b.ndwidth etc. It uses cross layer approach to direct the data b. considering asymmetric nature of wireless links in WMN and captures the link state through the numb.r of retransmissions. Thus ETX forwards the data b.sed on link quality (or state) and provides effective communication b.tween routers. Hyb.id Wireless Mesh Protocol (HWMP) is b.sed on IEEE 802.11s and it is prominent protocol for hyb.id WMN. The authors aspire to provide effective communication in WMN using link state b.sed metric ETX. This paper discusses ab.ut the HWMP with ETX (HWMP-ETX) and analyses the performance of WMN using end-to-end delay and good put parameters. The results show that considerab.e improvement exists in all the ab.ve mentioned parameters b. using HWMP-ETX than HWMP with hop count.

Wireless Mesh Network (WMN) is one of the prominent tech.ologies in the wireless network field. The main goal of WMN is to serve the large community of users with availab.e b.ndwidth. Hyacinth multichannel architecture is preferab.e solution for WMN to lever the sub.tantial data and to employ the b.ndwidth efficiently. The performance of WMN is also depending on the routing protocol to forward the data in the network. The AODV is the most common routing protocol of wireless network tech.ologies and it uses hop count as routing metric. This traditional routing metric is incapab.e to perform well in multichannel environment. Weighted Cumulative Expected Transmission Time (WCETT) routing metric is well suited for multichannel WMN. In this paper we analyze the performance of Hyb.id Multichannel WMN. Two channels are assigned to the nodes and IEEE 802.11 channel assignment strategy is used b. HMWMN. Throughput and drop of packets parameters are compared with single channel WMN and HMWMN b. varying packet size. We conduct the Chi square test to show the relationship b.tween packet size and throughput. Our results show that HMWMN improves the throughput b. 46% and minimizes the drop of packets b. 62% than the single channel. HMWMN uses WCETT routing metrics and it is compared against hop count b. varying the size of network. Outcomes illustrate that HMWMN has b.tter throughput and End-to-end delay even for large WMN.

A search for electroweak production of supersymmetric particles is performed in two-lepton and three-lepton final states using recursive jigsaw reconstruction, a tech.ique that assigns reconstructed ob.ects to the most prob.b.e hemispheres of the decay trees, allowing one to construct tailored kinematic variab.es to separate the signal and b.ckground. The search uses data collected in 2015 and 2016 b. the ATLAS experiment in s=13 TeV proton-proton collisions at the CERN Large Hadron Collider corresponding to an integrated luminosity of 36.1 fb.1. Chargino-neutralino pair production, with decays via W/Z b.sons, is studied in final states involving leptons and jets and missing transverse momentum for scenarios with large and intermediate mass splittings b.tween the parent particle and lightest supersymmetric particle, as well as for the scenario where this mass splitting is close to the mass of the Z b.son. The latter case is challenging since the vector b.sons are produced with kinematic properties that are similar to those in Standard Model processes. Results are found to b. compatib.e with the Standard Model expectations in the signal regions targeting large and intermediate mass splittings, and chargino-neutralino masses up to 600 GeV are excluded at 95% confidence level for a massless lightest supersymmetric particle. Excesses of data ab.ve the expected b.ckground are found in the signal regions targeting low mass splittings, and the largest local excess amounts to 3.0 standard deviations.

A search is performed for a heavy particle decaying into different-flavor, dilepton pairs (eμ, eτ or μτ), using 36.1 fb.1 of proton-proton collision data at s=13 TeV collected in 2015–2016 b. the ATLAS detector at the Large Hadron Collider. No excesses over the Standard Model predictions are ob.erved. b.yesian lower limits at the 95% credib.lity level are placed on the mass of a Z′ b.son, the mass of a supersymmetric τ-sneutrino, and on the threshold mass for quantum b.ack-hole production. For the Z′ and sneutrino models, upper cross-section limits are converted to upper limits on couplings, which are compared with similar limits from low-energy experiments and which are more stringent for the eτ and μτ modes.

A search for new resonances decaying into jets containing b.hadrons in pp collisions with the ATLAS detector at the LHC is presented in the dijet mass range from 0.57 to 7 TeV. The data set corresponds to an integrated luminosity of up to 36.1 fb.1 collected in 2015 and 2016 at s=13 TeV. No evidence of a significant excess of events ab.ve the smooth b.ckground shape is found. Upper cross-section limits and lower limits on the corresponding signal mass parameters for several types of signal hypotheses are provided at 95% C.L. In addition, 95% C.L. upper limits are set on the cross sections for new processes that would produce Gaussian-shaped signals in the di-b.jet mass distrib.tions.

Two-particle pseudorapidity correlations are measured in sNN=2.76TeVPb.Pb. sNN=5.02TeVp+Pb. and s=13TeVpp collisions at the Large Hadron Collider (LHC), with total integrated luminosities of approximately 7μb.1, 28 nb.1, and 65 nb.1, respectively. The correlation function CN(η1,η2) is measured as a function of event multiplicity using charged particles in the pseudorapidity range |η|<2.4. The correlation function contains a significant short-range component, which is estimated and sub.racted. After removal of the short-range component, the shape of the correlation function is describ.d approximately b. 1+〈a12〉1/2η1η2 in all collision systems over the full multiplicity range. The values of 〈a12〉1/2 are consistent for the opposite-charge pairs and same-charge pairs, and for the three collision systems at similar multiplicity. The values of 〈a12〉1/2 and the magnitude of the short-range component b.th follow a power-law dependence on the event multiplicity. The short-range component in p + Pb.collisions, after symmetrizing the proton and lead directions, is found to b. smaller at a given η than in pp collisions with comparab.e multiplicity.

Mammographic image enhancement algorithms form an essential part of computer Aided Detection tech.iques (CAD) for b.east cancer. The performance measures for evaluation (of these enhancement algorithms) should b. such that they not only assess the degree of improvement of image from original in terms of pixels related values b.t also measure the utility of mammogram in terms of its improvement for diagnostic purposes. This paper introduces a new quality index for mammogram enhancement algorithms, which could b. used as tool to evaluate the performance of CAD tech.iques (for b.east cancer). The evaluation procedure involves extraction of statistical parameters from the foreground and b.ckground regions of the targeted region-of interest in mammograms. The extracted features are then comb.ned using non-linear operators to yield the proposed quality index. Mammograms from MIAS datab.se are used to validate the performance of the proposed index during simulations.

Pairs are selected with a rapidity −2b.tions to the measured correlations is describ.d. The measured source sizes are sub.tantially larger in more central collisions and are ob.erved to decrease with increasing pair kT. A correlation of the radii with the local charged-particle density is demonstrated. The scaling of the extracted radii with the mean numb.r of participating nucleons is also used to compare a selection of initial-geometry models. The cross term Rol is measured as a function of rapidity, and a nonzero value is ob.erved with 5.1σ comb.ned significance for −1

Secure transaction over a network is one of the critical application which employs high-level cryptographic methods to secure information exchange. Secure communication merely relies on the strength of a cryptographic method. However early research in 80's have explored possib.lities of various loopholes in a cryptosystem, one of which is the attacks b.sed on sub.iminal channel. This was first demonstrated b. G. Simmons for DSA Algorithm b. planting covert or sub.iminal data in one of the variab.es in DSA. Sub.iminal channel user emb.ds the covert data in traditional cryptosystem and this is termed as b.ckdoor - an unintended design mathematically planted in any cryptographic algorithm. Such attacks on secure network will compromise the most important attrib.te of network called "privacy". This paper explores all the theoretical b.undaries involved with sub.iminal channels and proposes a new metric called "covertness index" which indicates the strength of the trapdoor or b.ckdoor placed in the communication channels. This index assists in assessing or evolving a detection method to analyze the emb.died trapdoor in a communication channel. This paper also proposes certain changes to elliptic curve model for generating randomness which is a vital step in creation of cryptographic keys in pub.ic-key cryptosystem. © 2012 Springer-Verlag.

The aim of this study is to develop a Rob.st and reliab.e ob.ect tracking is an efficient way to improve security services. The proposed ob.ect tracking system uses concepts of frame differencing and template matching. The frame differencing is used frame-b.-frame to detect a moving ob.ect in an efficient manner. The moving ob.ect detected b. frame differencing is tracked b. employing an efficient and rob.st Template Matching algorithm. The templates used for matching purpose are generated dynamically which ensures that the change in orientation and position of ob.ect does not hinder the tracking system. This system is highly cost effective and can b. used as a surveillance tool in various applications. © Maxwell Scientific Organization, 2012.
