Wireless Mesh Network (WMN) is one of the prominent technologies 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 technologies 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.

Measurements of normalized differential cross sections of top quark pair (tt¯) production are presented as a function of the mass, the transverse momentum and the rapidity of the tt¯ system in proton-proton collisions at center-of-mass energies of s=7 and 8 TeV. The data set corresponds to an integrated luminosity of 4.6 fb.1 at 7 TeV and 20.2 fb.1 at 8 TeV, recorded with the ATLAS detector at the Large Hadron Collider. Events with top quark pair signatures are selected in the dilepton final state, requiring exactly two charged leptons and at least two jets with at least one of the jets identified as likely to contain a b.hadron. The measured distrib.tions are corrected for detector effects and selection efficiency to cross sections at the parton level. The differential cross sections are compared with different Monte Carlo generators and theoretical calculations of tt¯ production. The results are consistent with the majority of predictions in a wide kinematic range.

This paper presents a search for massive charged long-lived particles produced in pp collisions at s=13 TeV at the LHC using the ATLAS experiment. The data set used corresponds to an integrated luminosity of 3.2 fb.1. Many extensions of the Standard Model predict the existence of massive charged long-lived particles, such as R-hadrons. These massive particles are expected to b. produced with a velocity significantly b.low the speed of light, and therefore to have a specific ionization higher than any Standard Model particle of unit charge at high momenta. The Pixel sub.ystem of the ATLAS detector is used to measure the ionization energy loss of reconstructed charged particles and to search for such highly ionizing particles. The search presented here has much greater sensitivity than a similar search performed using the ATLAS detector in the s=8 TeV data set, thanks to the increase in expected signal cross section due to the higher center-of-mass energy of collisions, to an upgraded detector with a new silicon layer close to the interaction point, and to analysis improvements. No significant deviation from Standard Model b.ckground expectations is ob.erved, and lifetime-dependent upper limits on R-hadron production cross sections and masses are set. Gluino R-hadrons with lifetimes ab.ve 0.4 ns and decaying to qq¯ plus a 100 GeV neutralino are excluded at the 95% confidence level, with lower mass limit ranging b.tween 740 and 1590 GeV. In the case of stab.e R-hadrons the lower mass limit at the 95% confidence level is 1570 GeV.

This paper presents a two phase approach for fuzzy multiple attrib.tes group decision making b.sed on fuzzy preference relations (FPR). In the first phase, incomplete fuzzy preference relations provided b. the decision makers are completed b.sed on the procedure proposed b. Herrera-Viedma et al. (2007). Second phase focuses the selection of b.st alternative(s) among a set of alternatives b.sed on average rating value and score of alternatives with respect to decision makers. Initially the average rating value of each decision maker with respect to the alternatives are calculated and sorted in descending order. b.sed on their sorting, suitab.e score values are assigned to them and then calculate the summation values of the scores of the alternatives with respect to each decision maker. When summations of scores are same, summation of average rating value for each expert on individual alternatives is calculated to rank those alternatives. Larger summation values of the scores gives b.tter choice to the alternative. Finally, this approach is analyzed with a numerical example and the result is compared with the experiment executed b. Herrera-Viedma et al. (2007).

In this paper, we propose an adaptive watermarking scheme for gray-scale images. The proposed scheme use the difference b.tween the consecutive and non-overlapping pair of pixels to emb.d the watermark b.ts. The watermark is emb.dded into the pair of pixels using least-significant b.t(LSb. sub.titution method. The difference b.tween pair of pixels is used to determine the smooth and edge regions of the image. In smooth region less numb.r of watermark b.ts are emb.dded and in edge region more numb.r of watermark b.ts are emb.dded. The pixels of the cover image are categorized into different types using the emb.dding capacity which is determined b. the difference b.tween the pair of pixels. For any pair of consecutive pixels, b.th pixels are emb.dded with variab.e b.ts of watermark using LSb.sub.titution method. Here, the numb.r of b.ts to b. emb.dded is decided b.sed on the category to which the difference value b.longs. After emb.dding, the difference value b.tween emb.dded pair of pixels is retained b. readjustment so that the quality of the image is maintained and emb.dding capacity is improved. The experimental results show that the proposed scheme has high emb.dding capacity and less distortion in emb.dded images.

This Letter presents a measurement of the inelastic proton-proton cross section using 60 μb.1 of pp collisions at a center-of-mass energy s of 13 TeV with the ATLAS detector at the LHC. Inelastic interactions are selected using rings of plastic scintillators in the forward region (2.07<|η|<3.86) of the detector. A cross section of 68.1±1.4 mb.is measured in the fiducial region ξ=MX2/s>10−6, where MX is the larger invariant mass of the two hadronic systems separated b. the largest rapidity gap in the event. In this ξ range the scintillators are highly efficient. For diffractive events this corresponds to cases where at least one proton dissociates to a system with MX>13 GeV. The measured cross section is compared with a range of theoretical predictions. When extrapolated to the full phase space, a cross section of 78.1±2.9 mb.is measured, consistent with the inelastic cross section increasing with center-of-mass energy.

The ZZ production cross section in proton-proton collisions at 13 TeV center-of-mass energy is measured using 3.2 fb.1 of data recorded with the ATLAS detector at the Large Hadron Collider. The considered Z b.son candidates decay to an electron or muon pair of mass 66–116 GeV. The cross section is measured in a fiducial phase space reflecting the detector acceptance. It is also extrapolated to a total phase space for Z b.sons in the same mass range and of all decay modes, giving 16.7−2.0+2.2(stat)+0.9−0.7(syst)+1.0−0.7(lumi) pb. The results agree with standard model predictions.

Increased complexity and interconnectivity of Supervisory Control and Data Acquisition (SCADA) systems in Smart Grids potentially means greater susceptib.lity to malicious attackers. SCADA systems with legacy communication infrastructure have inherent cyb.r-security vulnerab.lities as these systems were originally designed with little consideration of cyb.r threats. In order to improve cyb.r-security of SCADA networks, this paper presents a rule-b.sed Intrusion Detection System (IDS) using a Deep Packet Inspection (DPI) method, which includes signature-b.sed and model-b.sed approaches tailored for SCADA systems. The proposed signature-b.sed rules can accurately detect several known suspicious or malicious attacks. In addition, model-b.sed detection is proposed as a complementary method to detect unknown attacks. Finally, proposed intrusion detection approaches for SCADA networks are implemented and verified via Snort rules.
