The main aim of this paper is to provide stronger security for communication over the Internet by enhancing the strength of the AES algorithm. Rijndael's algorithm was selected as the Advanced Encryption Standard. The AES algorithm was believed to provide much more security without any limitations. But, recently some breaking methods on the AES have been found by cryptanalysts. In AES algorithm, the number of rounds involved in the encryption and decryption depends on the length of the key and the number of block columns. So, the number of rounds is increased to improve the strength of the AES. The strength of the AES algorithm is enhanced by increasing the key length to 512 bit and thereby the number of rounds is increased in order to provide a stronger encryption method for secure communication. Code optimization is done in order to improve the speed of encryption and decryption using the 512 bit AES. © EuroJournals Publishing, Inc. 2011.

Problem statement: Search queries are short and ambiguous and are insufficient for specifying precise user needs. To overcome this problem, some search engines suggest terms that are semantically related to the submitted queries, so that users can choose from the suggestions based on their information needs. Approach: In this study, we introduce an effective approach that captures the user's specific context by using the WordNet based semantic relatedness measure and the measures of joint keyword occurrences in the web page. Results: The context of the user query is identified and formulated. The user query is enriched to get more relevant web pages that the user needs. Conclusion: Experimental results show that our approach has better precision and recall than the existing methods. © 2011 Science Publications.

Let X ⊂ V be a set of vertices in a graph G = (V,E). The boundary B(X) of X is defined to be the set of vertices in V - X dominated by vertices in X, that is, B(X) = (V - X) ∩ N(X). The differential ∂(X) of X equals the value ∂(X) = |B(X)| - |X|. The differential of a graph G is defined as ∂(G) = max{∂(X)|X ⊂ V }. It is easy to see that for any graph G having vertices of maximum degree Δ(G), ∂(G) ≥ Δ(G)-1. In this paper we characterize the classes of unicyclic graphs, split graphs, grid graphs, k-regular graphs, for k ≤ 4, and bipartite graphs for which ∂(G) = Δ(G) - 1. We also determine the value of ∂(T) for any complete binary tree T.

A good quality single crystal of Tutton salt, (NH4) 2Fe(SO4)2·6H2O, with dimensions 6 × 7 × 3 mm3 was successfully grown by the slow evaporation growth technique at ambient temperature. The grown crystal was subjected to single crystal X-ray diffraction study which confirms that the grown crystal is monoclinic in nature with the space group P21/c. Optical absorption spectrum reveals that the grown crystal has good optical transparency in the entire visible region and its energy band gap was determined. The thermal behavior of the grown crystal was investigated by thermogravimetric and differential thermal analysis. The dielectric measurements were carried out to determine the dielectric behavior of the crystal. © 2012 Akadémiai Kiadó, Budapest, Hungary.

The development of biomaterials for the repair or replacement of hard tissue is a challenging and a promising area of research. Engineering cell and tissue behaviour at biomaterial surfaces at the nanoscale level can be accomplished by chemically modifying surfaces with biologically active macromolecules or physically modifying the surface topography at the nanoscale. Bioceramics have been used very successfully within the human body for many years. They are commonly used in orthopaedic surgery and dentistry but they are potentially suitable for a wide range of important applications within the medical device industry. The fabrication, microstructure and properties of this highly active area of research and the significance of a range of nanobioceramic coatings by electrochemical techniques are discussed. Bio-inspired materials open new approaches for manufacturing implants for bone replacement. The application of these nanobioceramic coating techniques to develop biomimetic coatings and scaffolds along with tissue engineering would set new trends in health care delivery system. The clinical applications of bioceramic coatings in joint replacement, bone grafts, tissue engineering, drug delivery systems and dentistry would serve as a useful resource for biomaterials scientists and engineers, as well as for clinicians and the academic community. © 2010 Maney Publishing.

Driver fatigue is an important contributor to road accidents. This paper reports a study that evaluated driver fatigue using multimodal fatigue measures, i.e., surface electromyography (sEMG), electroencephalography (EEG), seat interface pressure, blood pressure, heart rate and oxygen saturation level. Twenty male participants volunteered in this study by performing 60min of driving on a static simulator. Results from sEMG showed significant physical fatigue (ρ<0.05) in back and shoulder muscle groups. EEG showed significant (ρ<0.05) increase of alpha and theta activities and a significant decrease of beta activity during monotonous driving. Results also showed significant change in bilateral pressure distribution on thigh and buttocks region during the study. These findings demonstrate the use of multimodal measures to assess early onset of fatigue. This will help us understand the influence of physical and mental fatigue on driver during monotonous driving. © 2014 Elsevier Ltd and The Ergonomics Society.

Intrusion Detection Systems (IDSs) examine more features to detect the known and unknown attacks in computer network. Very few feature selection methods may be redundant or contribute something to the detection process, do not achieve greater detection accuracy and also not time consume. For reducing the time taken and achieving better classification accuracy through feature selection process, we introduced a new incremental model for effective intrusion detection. This proposed model is combining an incremental feature selection algorithm and classification algorithm. We propose, a new Incremental Feature Selection Algorithm called CRF and Fuzzy Rough Set based Feature Selection algorithm (IFSA) and the existing classification algorithm called Fuzzy ARTMAP Neural Classifier. The experimental results of the proposed model show that this model detects the intruders with less time and high detection rate when tested with KDD’99 cup data set. © Research India Publications.

Whilst motorcycling is an activity of pleasure in most parts of the world, in India it is a regular mode of commuting. Incidence of fatigue is substantially higher among motorcycle riders than drivers of other modes of transport. The objective of this study was to detect physical fatigue due to motorcycle riding for an hour using surface electromyography (sEMG) and seat interface pressure. Twenty healthy male participants performed 60 min of motorcycle riding in a low traffic density environment. Muscle activity was recorded bilaterally from extensor carpi radialis (ECR), biceps brachii (BB), trapezius medial (TM), sternocleldomastoid (S) latissimus dorsi (LD) and erector spinae (ES) muscle groups. Interface seat pressure distribution was monitored using a pressure mapping system. Results showed that participants have significant (p < 0.05) physical fatigue in TM, LD and ES muscle groups during 60 min of motorcycle riding. Seat pressure distribution was found to be non-uniform during the course of motorcycling. Results suggest that the impact on local physical fatigue and seat discomfort are probably due to static seating demand and prolonged sitting posture balance required to ride the motorcycle for an hour. © 2013 Elsevier Ltd.

The wear and friction behaviour of 7075 Al-25(wt %) SiC particle composite were investigated at a speed range of 3 to 9 m/s and load range of 30 to 110 N using pin-on-disc wear testing machine. In this work, the automobile friction material was used as pin and the composite as counter face and the results were compared with the commercially used cast iron brake disc. The results show that the wear rate of the Al MMC disc was less than that of the conventional cast iron disc. The coefficient of friction decreases with increase of applied load for both cast iron and Al MMC materials. However, the friction coefficient of Al MMC is higher than that of the cast iron. In all tests it is observed that the wear rate of friction material was more when sliding against MMC disc because of the abrasive action of fractured and pulled out SiC particles. The wear grooves formed on the cast iron disc, MMC disc and friction material have been analysed using optical micrographs and X- ray diffraction (XRD) technique. © 2014 Praise Worthy Prize S.r.l. - All rights reserved.
