Tea is one of the most widely consumed beverages all over the world due to its delicate taste. It is, therefore, essential to establish a simple and reliable analytical tool for determination (or, discrimination) of tea quality. We have taken an attempt to discriminate the black tea of different qualities/grades by means of polymer membrane electrode based potentiometric taste sensor. Different types of phosphorylated and crosslinked polymer membranes were used to discriminate different grades of black tea by measuring the tastes in terms of membrane potential.

Cloud computing has attracted great attention due its various features. There are various rising concerns in its growth, one of which is security. Trust between provider and a user is the most important factor to be considered for achieving security, which is also essential to promote the reputation of various cloud providers and their offered services. Here we present a trust based solution in terms of a trust model that can be used to calculate the security strength of a particular cloud service. The trust value acts as a means for selecting any cloud service.

This paper presents a study of and triboson production using events from proton-proton collisions at a centre-of-mass energy of recorded with the ATLAS detector at the LHC and corresponding to an integrated luminosity of 20.2 fb . The production cross-section is determined using a final state containing an electron, a muon, a photon, and neutrinos ( ). Upper limits on the production cross-section of the final state and the and final states containing an electron or a muon, two jets, a photon, and a neutrino ( or ) are also derived. The results are compared to the cross-sections predicted by the Standard Model at next-to-leading order in the strong-coupling constant. In addition, upper limits on the production cross-sections are derived in a fiducial region optimised for a search for new physics beyond the Standard Model. The results are interpreted in the context of anomalous quartic gauge couplings using an effective field theory. Confidence intervals at 95% confidence level are derived for the 14 coupling coefficients to which and production are sensitive.

Focus group discussion is an exploratory research technique used to collect data through group interaction. This technique provides the opportunity to observe interaction among participants on a topic under this study. This paper contributes to an understanding on the cyber terrorism conceptual framework through the analysis of focus group discussion. The proposed cyber terrorism conceptual framework which was obtained during the qualitative study by the authors has been used as a basis for discussion in the focus group discussion. Thirty (30) participants took part in the focus group discussion. The overall results suggest that the proposed cyber terrorism framework is acceptable by the participants. The present study supports our initial research that the cyber terrorism conceptual framework constitutes the following components: target, motivation, tools of attack, domain, methods of attack and impact.

There are reports of taste sensor fabrication by incorporating lipids in PVC matrix. We have taken an attempt to prepare taste sensor material by using functionalized polymer. Polyvinyl alcohol (PVA) and polyacrylic acid (PAA) have been modified to fabricate the sensor material. The research work covers polymer membrane preparation, morphology study, and structural characterization of membrane and study of the taste sensing characteristics. The membrane was prepared by cross-linking polyvinyl alcohol and polyacrylic acid in aqueous-organic medium by using hexadecyltrimethylammonium chloride (HDTC) with proper heat treatment. The cross-linked PVA-PAA was phosphorylated with POCl 3 . PVA-PAA membranes of suitable thickness were thus prepared with good threshold sensing value and less swelling in water. FTIR spectroscopic analysis, XRD analysis and optical microscopy were done to get an idea about the structure and morphology of the polymer membrane. Sensor device prepared with this membrane has shown distinct response patterns for different taste substances in terms of membrane potential. The sensor characteristics like temporal stability, response stability, response to different taste substances, and reproducibility of sensing performance were studied. Membranes also showed characteristic response patterns for organic acids like acetic acid, citric acid, formic acid, etc., mineral acids like HCl, H 2 SO 4 and HNO 3 , etc., salt, bitter substance, sweet substance, umami substance and different grades of tea. Sensor device prepared with this membrane has excellent shelf life.

Despite the increasing request for intelligent applications with the heavy use of smart phone, little of them are available in daily life. One reason must be the high complexity of understanding user's situation. For application (app) developers, knowing user's context usually takes much more time and efforts than taking some useful actions. To help developing intelligent apps, we have proposed a mobile context-aware engine called Intelligent Mobile Platform (IMP). It provides user's current context to apps as a background service in android mobile phones. Especially, depending on user's current environments such as location, active apps, etc., IMP dynamically extends or shrinks its knowledge base. We believe that this dynamic reconfiguration is essential for mobile environment where user continuously changes his/her location and contexts. In this paper, we describe the reconfiguration part in detail. This feature is tested by three in-house apps with the IMP prototype on SAMSUNG Galaxy S II phone.

File or data carving is a term used in the field of Cyber forensics. Cyber forensics is the process of acquisition, authentication, analysis and documentation of evidence extracted from and/or contained in a computer system, computer network and digital media. Extracting data (file) out of undifferentiated blocks (raw data) is called as carving. Identifying and recovering files based on analysis of file formats is known as file carving. In Cyber Forensics, carving is a helpful technique in finding hidden or deleted files from digital media. A file can be hidden in areas like lost clusters, unallocated clusters and slack space of the disk or digital media. To use this method of extraction, a file should have a standard file signature called a file header (start of the file). A search is performed to locate the file header and continued until the file footer (end of the file) is reached. The data between these two points will be extracted and analyzed to validate the file. The extraction algorithm uses different methods of carving depending on the file formats. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2011.

Nonstoichiometric Mn-doped ZnO magic nanoclusters and their composite structures from ab initio calculations

Ghaisas Vijay Kumar Centre for Development of Advanced Computing (C-DAC) Pune University Campus Pune–411 007 India Department of Electronic Science University of Pune Pune–411 007 India Department of Physics University of Pune Pune–411 007 India Dr. Vijay Kumar Foundation 1969 Sector 4 Gurgaon–122 001 India Center for Informatics School of Natural Sciences Shiv Nadar University Chithera Gautum Budh Nagar–203 207 Uttar Pradesh India

Undoped cages of (ZnO)n nanoclusters are magic with n = 12 and 34. However with Mn doping, our ab initio calculations show that O rich, nonstoichiometric Zn12MnO15 and Zn34MnO37 nanoclusters obtained from n = 13 and 35, become magic with 1μB magnetic moment. The Mn-doped nanoclusters can also be viewed as composite structures where a MnOx species (x = 1–4) is attached to (ZnO)n (n = 12 and 34) cages. Mn atoms can exist in a high oxidation state in these nanoclusters, with the highest binding energy for x = 3. Further replacement of Mn by Cr leads to a neutral, nonmagnetic Zn12CrO15 nanocluster with a large highest occupied molecular orbital and lowest unoccupied molecular orbital gap of 2.24 eV. These results provide new ground to understand doped nanostructures of ZnO and may also shed light on magnetism in Mn-doped ZnO thin films.

Automated face recognition offers an effective method for identifying individuals. Face images have been used in a number of different applications, including driver's licenses, passports and identification cards. To provide some form of standardization for photographs in these applications, ISO / IEC JTC 1 SC 37 have developed standardized data interchange formats to promote interoperability. There are many different publically available face databases available to the research community that are used to advance the field of face recognition algorithms, amongst other uses. In this paper, we examine how an existing database that has been used extensively in research (FERET) compares with two operational data sets with respect to some of the metrics outlined in the standard ISO / IEC 19794-5. The goals of this research are to provide the community with a comparison of a baseline data set and to compare this baseline to a photographic data set that has been scanned in from mug-shot photographs, as well as a data set of digitally captured photographs. It is hoped that this information will provide Face Recognition System (FRS) developers some guidance on the characteristics of operationally collected data sets versus a controlled-collection database. © 2011 IEEE.

Fusion approach for matchfingerprint matchinginging for improved system accuracy

International Journal of Computer Science Issues 2011年第2期8卷 583-589页

In automated fingerprint identification systems, an efficient and accurate alignment algorithm in the preprocessing stage plays a crucial role in the performance of the whole system, affecting greatly the speed and accuracy otherwise. This paper proposes a fusion scheme (weighted sum) for aligning the enrolled and query images using modified ring model and cross correlation approaches. Both the methods align the pair of fingerprint images based on the single singular point (as a reference point). Matching is then performed using Euclidean distance based matcher. This model is tested on both publicly available (Cross Match Verifier 300 sensor) as well as proprietary (Lumidigm Venus V100 OEM Module sensor) fingerprint databases scanned at 500 dpi. The experiments show that this fusion approach improves the overall system accuracy: FNMR and FMR significantly dropped to 3.23% & 2.67% respectively for Cross Match Dataset and 0% & 1.33% respectively for Lumidigm Dataset. Hence, the combination of these two alignment methods effectively strengthens the performance of the matcher.
