Abstract

Finger-Knuckle-Print (FKP) uses feature detection and matching techniques in its hard core design. It works similar for almost every authentication system. The Scale Invariant Feature Transform (SIFT) is the most reliable feature extraction technique that is used in authentication systems on FKP. The feature descriptors detected by SIFT claim to be capable of distinguishing each and every image in the dataset from one another with the cost involved in its operations. In SIFT based FKP authentication systems, the storage and computational cost will directly depend on the size of the feature descriptors used. Such matching process will directly match these feature descriptors to find an exact match and the descriptors were directly stored in storage media as templates. Hence there is a necessity for storing all the feature descriptors of the enrolled FKP images for future references. The size of these feature descriptors data will be greater than the original FKP image dataset and the performance of the system will rapidly decrease with respect to the increase in enrollment in the database. The proposed work address these issues with FKP based authentication system using SIFT for efficient computation and cost compared with the existing work and proven to be secure and tough resistant for authentication system.

Abstract

This work focus on using evidence for making access control decisions in present computing environments. These environments create new interaction scenarios that traditional access control approaches handle poorly. This approach views access control as the filtering of messages between communicating services. This work implements the evidence-based approach with a mechanism analogous to a network firewall, filtering messages going to and from a service.
The main goal of this work is it supports communication between parties in different trust domains, allow evidence associated with parties to be securely collected and evaluated for the purpose of allowing access to resources, create an ecosystem in which evidence providers can flourish.
This will describe the design of the evidence-based access models; discuss usage scenarios, and present preliminary results.
The results suggest that this approach is flexible enough to accommodate interesting present computing scenarios and efficient enough to implement on small devices.

Abstract

Object oriented systems are the main choice in the world scene today for development of high quality systems and object oriented metrics are shaping the way quality is perceived in these systems. This paper does an evaluation of the suitability of the various object oriented metrics across three popular Object Oriented programming languages-C++, Java and C#. The paper then analyzes the results that are arrived at. These evaluation results will help in selecting the proper set of metrics for a particular object oriented language.

Abstract

Security engineering is a new research area in software engineering that covers the definition of processes, plans and designs for security. The researchers are working in this area and however there is a lack in security requirements treatment in this field. The security requirements is one of the non functional requirements which acts as constrains on the functions of the system. An increasing part of the communication and sharing of information in our society utilizes electronic media. Many organizations, especially distributed and Net-centric are entirely dependent on well functioning information systems. Thus IT security is becoming central to the ability to fulfill business goals, build trustworthy systems, and protect assets. In order to develop systems with adequate security features, it is essential to capture the corresponding security needs and requirements. Security requirements engineering is emerging as a branch of software engineering, spurred by the realization that security must be dealt with early during requirements phase. A number of researchers' proposals have major limitations as they treat security in system oriented terms. In this paper we present a view on Security Requirements, Security Requirements issues, types, and the framework for Security Requirements Engineering. We also have presented about the challenges to web application security and evaluated the Security Requirements Engineering framework for web applications.

Abstract

Timetabling means scheduling activities to time slots in an order by satisfying hard constraints and soft constraints. Hard constraints should be satisfied but the violations of soft constraints to be minimized. This problem can be done in Artificial Intelligence or Operations Research domain. Class Timetabling of Undergraduate Science courses of Pondicherry University was implemented using Steepest-Ascent Hill Climbing algorithm and is compared with the proposed approach with heuristics for class timetabling implementation. By analyzing the results obtained in both the methods, significance of applying heuristics to get the optimal solution has been established.

Abstract

In the context of achieving a national set target of 60 GW by 2022, a study was carried out in Kayathar, Tuticorin district, Tamil Nadu, India on noise propagation from wind turbines. Acoustic and non-acoustic parameters were measured according to IEC 61400-11 at wind speeds of 4-13 and 0.7-8.6 m/s. The onsite measurements were compared with ISO 9613-2; this showed a difference of ± 5 dB(A) for every increment in the distance. An equation was derived to obtain sound pressure level (dB(A)) at the base of the tower for wind turbines at varying distance of measurement.

Abstract

Increasing urbanization and industrialization have resulted in a dramatic increase in the volume of wastewater. Global water pollution scenario suggests that nearly 1.5 billion people lack safe drinking water and at least 5 million deaths are attributed to waterborne diseases such as cholera, hepatitis every year. The textile industry plays an important role in Indian economy. The textile dyeing wastewaters are highly coloured due to the release of unfixed dye molecules in the dyeing process. The traditional treatment techniques applied in textile wastewaters, such as coagulation/flocculation, membrane separation (ultrafiltratation, reverse osmosis) or elimination by activated carbon adsorption, only do a phase transfer of the pollutant, and biological treatment is also not a complete solution to the problem. So Advanced Oxidation Processes (AOP's), like ozonation and ozonation combined with hydrogen peroxide and UV source, could be a good option to treat and eliminate textile dyes. Advanced Oxidation Processes are the one that offers a highly reactive, non-specific oxidant namely hydroxyl radicals (HO•), capable of destroying wide range of organic pollutants in water and wastewater. In the present study, colour removal on synthetic textile dyeing wastewater (SWW) Reactive orange was performed using ozone and ozone based AOPs such as O₃/UV, O₃/H₂O₂ and O₃/UV/H₂O₂. The decolorization of dye has been investigated in terms of change in color by measuring absorbance.

Abstract

There are currently an estimated 15 million blind people in India. 6.8 million of these suffer from corneal blindness with vision less than 6/60 in at least one eye, and of these, about 1 million have bilateral corneal blindness. If the present trend continues, it is expected that the number of corneal blind individuals in India will increase to 10.6 million in 2020.

Abstract

This work deals with the performance of a microbial fuel cell, focusing on the electrocatalytic activity of selected cathodes constructed by coating nanocomposites over graphite felt under neutral pH in a doublechamber configuration using paper-recycled waste water as a typical electrolyte. Among all cathodes, iron phthalocyanine (FePc) combined multiwalled carbon nanotubes (MWCNT) shows the highest power density (9.34 W/m²) compared to other two catalysts, FePc/Ketjan black (4.68 W/m²) and MWCNT (2.9 W/m²) under similar conditions of using a reference platinum/carbon (Pt/C) loading of 0.5 mg/cm². The morphology of these catalyst coated electrodes was characterized by scanning electron microscopy. Their electrocatalytic activities were examined using cyclic voltammetry. This work provides an appropriate alternative for cathode catalysts in treatment as well as in electricity production as demonstrated by the high power density of the above catalysts compared to that using precious Pt metal catalyst in microbial fuel cells.
