Analysis of Security in Wireless Network: A Survey

Information security maintenances with the truthfulness, accessibility, and secrecy of knowledge irrespective of the arrangement of the information might take. Data security is frequently branded in different ways like in connected and non-connected security. Non-connected grid security varies with execution prerequisites. The proposed study of worries and safety mechanism stages accessible in non-connected networks. The anticipated representations for non-connected networks are grounded on diverse significances for sanctuary and effortlessness.

Design of a Differential Safety Mechanism (DSM) Dedicated to the NSW Micromegas Wedges

The New Small Wheel Micromegas detector system for the Upgrade of ATLAS Muon Spectrometer is in the phase of integration and commissioning at the Laboratories BB5 and Building 191 at CERN respectively. In this framework, the produced modules are evaluated and tested at a Cosmic Ray Stand or at their final position on New Small Wheel. Providing gas mixture to the Micromegas Wedges, the static gauge pressure inside the detector’s layers must be kept below a nominal value around 3 mbar. Pressures above 10 mbar, due several reasons or gas line blocking, could cause serious damages in the detectors. In this work we describe the principle of operation and the design of a low cost intelligent unit, the “Differential Safety Mechanism”, dedicated to protect the Micromegas Wedges against unexpected slow or sudden increase of the static gauge pressure. The internal detailed structure, the simulation and the prototype tests of the DSM are presented analytically in this work.

A visual approach towards forward collision warning for autonomous vehicles on Malaysian public roads

Background: Autonomous vehicles are important in smart transportation. Although exciting progress has been made, it remains challenging to design a safety mechanism for autonomous vehicles despite uncertainties and obstacles that occur dynamically on the road. Collision detection and avoidance are indispensable for a reliable decision-making module in autonomous driving. Methods: This study presents a robust approach for forward collision warning using vision data for autonomous vehicles on Malaysian public roads. The proposed architecture combines environment perception and lane localization to define a safe driving region for the ego vehicle. If potential risks are detected in the safe driving region, a warning will be triggered. The early warning is important to help avoid rear-end collision. Besides, an adaptive lane localization method that considers geometrical structure of the road is presented to deal with different road types. Results: Precision scores of mean average precision (mAP) 0.5, mAP 0.95 and recall of 0.14, 0.06979 and 0.6356 were found in this study. Conclusions: Experimental results have validated the effectiveness of the proposed approach under different lighting and environmental conditions.

A novel Veress needle mechanism that reduces overshooting after puncturing the abdominal wall

Background Complications that occur in laparoscopic surgery are often associated with the initial entry into the peritoneal cavity. The literature reported incidences of Veress needle (VN) injuries of e.g. 0.31% and 0.23%. In a 2010 national survey of laparoscopic entry techniques in the Canadian General Surgical practice, 57.3% of respondents had either experienced or witnessed a serious laparoscopic entry complication like bowel perforation and vascular injury. As those complications are potentially life threatening and should be avoided at all costs, improving safety of this initial action is paramount. Methods Based on a bare minimum design approach with focus on function expansion of existing components, a new Safety mechanism was developed for the VN that decreases the risks of VN overshooting. The mechanism works by preventing the puncturing acceleration of the tip of the VN by decoupling the surgeon’s hand from the VN immediately after entering the abdomen. Results Based on a set of requirements, a first prototype of the VN+ with force decoupling safety mechanism is presented and evaluated on an ex vivo porcine abdominal wall tissue model in a custom setup. The experiments conducted by two novices and one experienced surgeon indicated a significant difference between the attempts with a standard, conventional working VN (41.4 mm [37.5–45 mm]) and VN+ with decoupling mechanism (20.8 mm [17.5–22.5 mm]) of p < 0.001. Conclusion A new decoupling safety mechanism was integrated successfully in a standard VN resulting in a VN+ . The results from the pilot study indicate that this new VN+ reduces overshooting with a minimum of 50% in a standardised ex vivo setting on fresh porcine abdominal wall specimens.

Application and implications of digital signatures and certificates within the framework of law 27269 - Peru

This research seeks to identify the befits of the application and implications in Peru of Law No. 27269 "Law on Digital Signatures and Certificates", modified by Law No. 27310 and how its application has contributed to the progress of its optimization in the public and private sphere within the framework of the establishment of electronic government in Peru and more than 19 years after its entry into force, the Regulation of Law No. 27269, approved by Supreme Decree No. 052-2008-PCM, seeks to regulate the use of digital signatures and the regime of the official infrastructure of the electronic signature, looking for different levels of guarantee and security in order to give the same legal effectiveness and validity that is given to the same legal effectiveness and validity that is given to the official infrastructure of the electronic signature. 052-2008-PCM, seeks to regulate the use of digital signatures and the regime of the official infrastructure of the electronic signature, looking for different levels of guarantee and security in order to give the same legal effectiveness and validity that is given to the handwritten or other similar signature, however there have been problems for its application, which we will analyze in order to propose possible alternatives for a better control and safety mechanism.
