As the dependency on Internet is increasing, the service providers are launching numerous web applications to facilitate the users. Due to threat of unauthorized access they want to identify their users accurately. In the same way, leakage of sensitive information makes clients aware enough to make sure whom they are dealing with. This leads to the requirement of a Centralized Authentication System(CAS). The involvement of CAS introduces the single sign on capability at client side. Once the individual proves his identity to the CAS, it will be assured to all those services that trust on CAS. There are several existing solutions like Kerberos and SAML. This paper introduces a single sign-on protocol which combines the protocol architecture of Kerberos with the functionality of SAML. Finding the deficits in the SAML architecture we try to improve it by adapting strong protocol architecture. As a proof of concept, we study the formal analysis of the proposed security protocol through different tools like CASPER and SCYTHER. © 2016 IEEE.

Post Graduate course viz. Management course inculcates the attributes that are to be assessed for every student. These attributes include ability to investigate, Ability to network and resourceful, independent and critical thinkers, subject specialist, confident, excellent communication skills, collaborator, adaptable etc. are the area of concern. The presence of necessary management attributes guarantees success of a student and is gauged by assessing course outcomes of students. This paper proposes an approach to identify the in competencies in a management graduate by identifying the weak students who do not possess the attributes. The paper also suggest the means to improve the gap during the course delivery. © 2015 IEEE.

Health care waste includes all the waste generated by health care establishments, research facilities, and laboratories. This constitutes a variety of chemical substances, such as pharmaceuticals, radionuclides, solvents, and disinfectants. Recently, scientists and environmentalists have discovered that wastewater produced by hospitals possesses toxic properties due to various toxic chemicals and pharmaceuticals capable of causing environmental impacts and even lethal effects to organisms in aquatic ecosystems. Many of these compounds resist normal wastewater treatment and end up in surface waters. Besides aquatic organisms, humans can be exposed through drinking water produced from contaminated surface water. Indeed, some of the substances found in wastewaters are genotoxic and are suspected to be potential contributors to certain cancers. The aim of this study was to evaluate the genotoxic and cytotoxic potential of wastewaters from two hospitals and three clinical diagnostic centers located in Jaipur (Rajasthan State), India using the prokaryotic Salmonella mutagenicity assay (Ames assay) and the eukaryotic Saccharomyces cerevisiae respiration inhibition assay. In the Ames assay, untreated wastewaters from both of the health care sectors resulted in significantly increased numbers of revertant colonies up to 1,000-4,050 as measured by the Salmonella typhimurium TA98 and TA100 strains (with and without metabolic activation) after exposure to undiluted samples, which indicated the highly genotoxic nature of these wastewaters. Furthermore, both hospital and diagnostic samples were found to be highly cytotoxic. Effective concentrations at which 20 % (EC20) and 50 % (EC50) inhibition of the respiration rate of the cells occurred ranged between ∼0.00 and 0.52 % and between 0.005 and 41.30 % (calculated with the help of the MS excel software XLSTAT 2012.1.01; Addinsoft), respectively, as determined by the S. cerevisiae assay. The results indicated that hospital wastewaters contain genotoxic and cytotoxic components. In addition, diagnostic centers also represent small but significant sources of genotoxic and cytotoxic wastes. © 2013 Springer-Verlag Berlin Heidelberg.

We propose a null-cone representation for interacting world lines. The Feynman graphs of the fundamental interactions are recast in null-cone representation. Topology of the causal structure of these representations is found to be on firm footing. This exercise in turn further strengthens the foundations of special relativity. © 2012 Physics Essays Publication.

Purpose - The purpose of this paper is to develop a new criterion for the exponential stability and H∞ performance of state-space digital filters under the influence of any combination of quantization/ overflow nonlinearities. Design/methodology/approach - The proposed criterion uses the H∞ approach that is suitable for the design of discrete system in the presence of external disturbance. Analysis and synthesis in an H∞ setting is advantageous as it proposes effective disturbance attenuation, less sensitivity to uncertainties and many practical applications. Findings - The criterion not only guarantees exponential stability but also reduces the effect of external interference. A numerical example demonstrating the effectiveness of the proposed method is given. Originality/value - The main result of the paper is reported for the first time and it is useful to ensure the stability of digital filters in the presence of external disturbance and any combination of quantization/overflow nonlinearities. © Emerald Group Publishing Limited.

Graduate Attributes (GAs) in Outcome Based Education (OBE) are the outcomes (of the stake holder especially students) which are to be assessed during their programme of studies. Some of the graduate attributes can be addressed through project based teaching learning process. The indirect assessment approach helps the students to know their strengths and weaknesses in a particular area. The paper presents a methodology adopted for the assessment of graduate attributes through typical technical (project based) events which are organized and managed by the students with assessment rubrics that provide the information about their approach of learning as well as teaching. The paper also presents the assessment through the teaching and learning process, an indirect path to assess the programme outcomes. © 2015 IEEE.

Course outcome assessment is a pre-requisite for any programme to assess the performance of the student during the programme of study. Corrective actions are planned accordingly for the achievement of the same. The paper discusses the methodology for the assessment of course outcome of an individual student against pre-defined target. The assessment and analysis also provide the path to mobilize the different activities in the programme and serve as content beyond syllabus. Further, the cumulative assessments of the course outcomes are then used as one of the tool for the assessment of programme outcomes. © 2015 IEEE.

This is the first report ever on La3+-Nd3+ doped M-type hexaferrite nanoparticles: SrNdxLayFe12-x-yO19 (0 ≤ x ≤ 1) prepared by citrate precursor using the sol-gel technique followed by gel to crystallization. The substitution effects of ions and molar ratio of Fe3+/Sr2+ on the formation of ferrite phase were examined using powder differential thermal analysis (DTA) technique, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (Mid-IR) and vibrating sample magnetometer (VSM). The present work aim to study the crystallization of binary La3+- Nd3+ doped hexaferrite nanoparticles. DTA technique was employed to investigate the formation of nanocrystalline SrNd0.4La0.4Fe11.2O19 and revealed that the formation of ferrite phase was occurred in steps and crystallization take place by the means of endothermic reactions. The value of activation energy and crystallization temperature has been obtained from DTA data using different non-isothermal methods. XRD and Mid-IR studies have confirmed the formation of ferrite phase. Through this work an optimum calcination condition was established for the synthesis of single phase hexaferrite nanoparticles even after the substitution of binary rare earth elements. Magnetic properties were determined by using a vibrating sample magnetometer. The magnetic results revealed that the synthesized nanoparticles are suitable for perpendicular recording media due to their high coercivity value. © 2015 Elsevier B.V.

This demo depicts a low cost virtual reality set-up that may be used for medical training and instruction purposes. Using devices such as the Oculus Rift and Razer Hydra, an immersive experience, including hand interactivity can be given. Software running on a PC integrates these devices and presents an interactive and immersive training environment, where trainees are asked to perform a mixed bag of both, simple and complex tasks. These tasks range from identification of certain organs to performing of an actual incision. Trainees learn by doing, albeit in the virtual world. Components of the system are relatively affordable and simple to use, thereby making such a set-up incredibly easy to deploy. © 2015 IEEE.
