Indian J envir Prot 2003, 23(7), 792-9.
The earthworm, Lambito Mauritii (Kinberg) were exposed to various concentrations of cadmium and mercury in soil and water medium. The 24 hr LC50 value of cadmium and mercury in water environment was 1.1 and 0.09 mg/L, respectively and in soil medium it was found to be 800.7 and 336.6 mg/kg. The various behavioral changes observed were burowing, fast movement, lifting of the body, curling and coiling. The morphological changes were rupture of the cuticle, blood accumulation, constriction, bulging, oozing out of blood and oozing out of coelomic fluid. In all the concentrations tested the time taken for the initiation of morphological changes decreased.

Reuse promises increased productivity and enhanced product quality. A good deal of reseach in this area has gone into identifying types of possible reuse types and technologies for the purpose. The experience of the industry shows that organizations are not comfortable in practicing reuse. An attempt has been made to identify the reasons (technical) impeding reuse oriented software development. Introductory remarks about resue itself, its types etc. for describing the reuse scenario have been given. The research works reported in the literature normally talk about organizational issues whereas this paper considers the technical issues to present the clearer picture. Finally observations and propositions for making reuse practice is given a regular part of the development process. The basic observation put forth is the idea that reuses need to be inculcated in the development process. Time is ripe now has come for "Reuse Oriented Software Process" concept.

In knowledge discovery from databases and warehouses, there is an ongoing number of algorithms and practices that can be used for the very same application, for example to predict the value of a specific field. These algorithms are trained on a portion of the original data set and are tested on the remaining data set for their accuracy. Furthermore, the estimated value of the target field is often tested against a second data set for evaluation purposes. Factors affecting the performance is examined, as it is defined by the produced error rate, of some popular predictive data mining alogrithms such as decision trees, neural nets, regression etc, on many data sets from different sources. These factors may be either the number of attributes, the type of each field, the number of missing values etc. Finally, it is tested whether it is possible to gauge a priori which algorithm (s) will produce the lowest error rate of each specific data set. As a result some heuristic rules are to be listed in order to facilitate the decision maker in selecting the best possible technique.

Focus has been placed on the performance prediction of wireless local loop system in terms of blocking probabilities of the calls. A traffic model based on queue theoretic approach has been developed. For solution purpose, product type solution is employed. Analysis is brought about by comparing various situations of prioritizing the handoff calls by reserving the channel, allowing new calls to be entertained in this reserved area if the handoof calls are less and further offering facilities to handle more handoff voice calls by subrating the reserved channel. All of the above situations are computed analytically as well as using Artificial Neural Network (ANN) which is the fastest growing technique of soft computing. A feed forward two layer ANN is considered for obtaining the blocking probabilities. The back propagation algorithm is used for training the ANN. All the aboe situations are compared using numerical illustrations.

One of the efforts to capture market in the area of Information Technology, witnessed in many cases, locally, has been to move from H/w devices embodying the core technology to offer corresponding S/w packages. This has become possible with advent of new generation of microcomputers providing the processing power and storage capacities comparable to the so called supercomputers of late 1980's. The entire move has added to possibility of achieving the functionality of the H/w through the S/w and may not prove useful for "Online processing" applications. Again the "expression" is covered only under the Copyright Act wherein the underlying idea to achieve the functionality is not protected. Undoubtedly, the S/w solutions offer extensive price performance advantage (typically 2 to 8) but this trend has witnessed easy access to the built-in technology leading to IPR proliferations and infringements. This has called to the current movement of the IPR Safety Technologies. Digital Signal Processors (DSP's), who also provide adaptable computational features commensurate with the target applications have emerged as the most important weapons to keep the Intellectual Property Rights remain safe and also add to the extreme miniaturization, low power ratings and enhanced performances. The present report reviews their historical development, architectures, markets, applications, technological breakthroughs and their capacity to work as Technology Driver as witnessed globally....

Most of the existing methods of Software Reliability Allocation (SRA) badly rely on the experiential data and are based on nonlinear optimization with specified objective function. In this paper, we have proposed a method which integrates users' requirements and preferences with the technical structure comprising components (functions, programs, and modules) at different levels of abstraction. Reliability allocation to the components is guided by taking users view on importance of each component and considering utility and cost of development of the software. Since, we have integrated the users view about software functions and their relative importance to the user with the Software Engineers (SE) and programmers (PR) view of the structure of software in terms of programs and modules, the use of linear equations will work and the complexity of optimization will be greatly reduced.

Powerful computers are needed for processing tasks related to human languages these days. Human languages, also called natural languages, are highly versatile systems of encoding information and can capture information of various domains. To enable a computer to process information in human languages, the language needs to be appropriately 'described' to the computer, i.e. the language needs to be 'modelled'. In this work, we present an approach for acquisition of morphology of inflectional language like Hindi. It is an unsupervised learning approach, suitable for languages with a rich concatenative morphology. Broadly, our work is carried out in three steps: 1. Acquire the morphology of Hindi from a raw (un annotated) Central Institute of Indian Languages (CIIL), Mysore text corpus, 2. prepare clusters and prepare stem bag and suffix bag, 3. use the morphological knowledge to decompose given word as stems and suffixes according to their morphological behaviour and add new words. A prime motivation behind this work is to eventually develop an unsupervised morphological analyser which is language-independent (used for Hindi). Second motivation is to develop a Morphological segmentation which is language-independent as it is shown that study of morphology would benefit to a range of NLP tasks such as speech recognition, speech synthesis, machine translation and information retrieval. Though Hindi is an important and a national language in India, little computational work has been done so far in this direction. Our work is one of the first efforts in this regard and can be considered pioneering. There are many such languages for which it is very important to have a suitable but inexpensive computational acquisition process. Languages receive very little attention of computational linguistic research both in terms of availability of funds and number of researchers. We however do not claim that our approach is a solution for all such languages. Different languages have characteristics that require individual research attention.

The principal goal of data mining can be described as finding useful information in a vast amount of data. The recent appearance of sources of huge heterogeneous data made it difficult to use, As people are getting more and more online, their privacy is at stake; so web technologies should be idle with user profiles can be maintained. In this paper, presents sound and complete SHEN scheme for the web sponsored consortium on the support of data mining in business today. Based on this scheme, we construct a condensed representation of all frequent item sets; this scheme is not restricted to HTTP only. It can also be used among other internet services. This scheme allows the client to send certificate for authentication by using Secure Sockets Layer. This scheme is simpler but rather more secure than the Spyglass proposal; in particular the scheme is secure against a person-in-the-middle attack. We also present connections between our proposals and recent other proposals for condensed representations of frequent item sets. Experiments on real-life datasets show the effectiveness of the SHEN scheme.

As the popularity of mobile devices (MDs) and wireless networks significantly increased over the past years, wireless ad hoc networks has now become one of the most vibrant and active fields of communication and networking research. A MANET (Mobile Ad-hoc Network) is a collection of wireless nodes that can dynamically form a network to exchange information without using any preexisting fixed network infrastructure. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. Due to severe challenges, the special features of MANET bring this technology great opportunistic together. This paper describes the fundamental problems of ad hoc network by giving its related research background including the concept, features, status, and applications of MANET. This paper presents an overview and the comparative study of the routing protocols. Also include the several challenging issues and the future work.

In this paper, authors propose a novel scheme towards the recognition of multi-oriented and multi-sized isolated characters of printed script. For recognition, at first, distances of the outer contour points from the centroid of the individual characters are calculated and these contour distances are then arranged in a particular order to get size and rotation invariant feature. Next, based on the arranged contour distances, the features are derived from different class of characters. Finally, we use these derived features of the characters to statistically compare the features of the input character for recognition. We have tested our scheme on printed Bangla and Devnagari multi-oriented characters and we obtained encouraging results.

The focus of this paper is to automatically segment and label continuous speech signal into syllable-like units for Indian languages. In this approach, the continuous speech signal is first automatically segmented into syllable-like units using group delay based algorithm. Similar syllable segments are then grouped together using an unsupervised and incremental training (UIT) technique. Isolated style HMM models are generated for each of the clusters during training. During testing, the speech signal is segmented into syllable-like units which are then tested against the HMMs obtained during training. This results in a syllable recognition performance of 42.6% and 39.94% for Tamil and Telugu. A new feature extraction technique that uses features extracted from multiple frame sizes and frame rates dur-ing both training and testing is explored for the syllable recognition task. This results in a recognition performance of 48.7% and 45.36%, for Tamil and Telugu respec-tively. The performance of segmentation followed by labelling is superior to that of a flat start syllable recogniser (27.8% and 28.8% for Tamil and Telugu respectively).

We believe that these systems will become the future of mathematics, where definitions, statements, computations and proofs are all available in a computerized form. An important application is and will be in computer supported modelling and verification of systems. But there is still a long road ahead and I will indicate what we believe is needed for the further proliferation of proof assistants.

MANETs can be differentiated by multi-hop and, constantly changing topology. While mobile ad hoc networks have no fixed infrastructure, their use is also being regarded as an augmentation to the Internet. These Network uses radio frequency as their physical medium for communication. Transmission Control Protocol (TCP) is a transport layer protocol and is planned for a wired network that handles network congestion successfully. It is end-to-end connection oriented transport layer protocol that gives byte stream based service. TCP is transports a considerable segment of Internet transmission such as e-mail (SMTP) file transfers (FTP) and WWW (HTTP). Thus, the use of TCP,is mobile ad hoc networks is clearly advantageous. Because of their defining characteristics (e.g., time varying, dynamic, multi-hop, and, constantly changing topology), mobile ad hoc networks may have link failures resulting in poor performance of TCP congestion control, When TCP is executed over Wireless Network, the loss will due to the unreliable nature of wireless link rather than by congestion. But, TCP believes that the loss is due to congestion and responds by congestion control algorithm which degrades throughput, delay, and finalizing with useless bandwidth operation. There are some problems in making a transport layer protocol for wireless Network like induced traffic, induced throughput unfairness, separation of congestion control, reliability, and flow control etcetera. There are some processes for transport layer solution that are based on the two approaches can be classified into three groups (1) End-to-end approach, (2) Split approach, and (3)and other protocols that are not based on TCP. These schemes are compared and a complete detail is generated in this paper.

Remote procedure calls (RPCs) lie at the heart of any client/server software. Thus, formal specification and verification of RPC mechanisms is a pre-requisite for the verification of any such software. In this paper, we present a math-ematical specification of an RPC mechanism and we outline how to prove the cor-rectness of an implementation - say written in C - of this mechanism at the code level. We define a formal model of user processes running concurrently under a sim-ple operating system, which provides inter-process communication and portmapper system calls. A simple theory of non-interference permits us to use conventional sequential program analysis between system calls (within the concurrent model). An RPC mechanism is specified and the correctness proof for server implementa-tions, using this mechanism, is outlined. To the best of our knowledge this is the first treatment of the correctness of an entire RPC mechanism at the code level.

Information systems do not usually incorporate public serving interfaces, to obviate the necessity of physical queues. This is because information systems and queuing systems address two entirely unconnected domains. The requirements of queuing and load balancing for serving the public faster and efficiently can be quite complex. The token indication systems available in the market are generally stand alone, bulky and are generally not designed to cater to complex queuing requirements. The hardware (already available owing to requirements of Information system) could be synergically utilized, to provide complex queuing solutions, through networking while such a solution remains a separate entity from the information system. On these lines we have developed a patient call system for BARe Hospital and installed a prototype system at the Surgical Unit.

In this communication, the effect of interrelation between cross catalysis and autocatalytic processes on the nature of attractorhas been investigated. Rossler's model for deterministic chaos has been modified by inclusion of cross-catalysis. With this slight change in the model, the nature of attractors differs, although chaos is observed in the definite range of values of parameters. In contrast with earlier models involving two autocatalytic processes, attempt has been made to analyse the situation when three autocatalytic processes involving the three variables x, y and z and when (i) there is cross-catalysis and (ii) there is no cross catalysis. Deterministic chaos is still observed in such cases. However, characteristics of the attractor differ which have been specified.

Swarm intelligence algorithms are developed to solve different aspect of the complex "First Responder Sensor Network" for emergency personnel. Swarm intelligence algorithms can solve both design problems as well as real-time processing problems. In this paper, two particle swarm optimization algorithms are developed to solve a complex design problem and, for contrast, multilateration, a real-time signal-processing problem. A novel signal design technique is developed to design an ultra-wideband signal that supports communications as well as estimating location inside buildings and in hazardous conditions where GPS is unavailable. With the real-time processing in this network, propagation time is measured so that the location is estimated by a multilateration algorithm. The PSO based multilateration algorithm fuses time measurements from three or more sensors to locate a person in a two coordinate system.

Unit testing is one of the most effective techniques to find defects at an early stage, which reduces the testing and maintenance efforts exponentially at the later phase. It becomes more important when the environment is global software development, where the software developers are disparate over the different environments and places. In this paper, we suggest to apply cognitive weight complexity metric (CWCM) for unit testing in a global software development environment. On the contrary, to the other metrics, CWCM calculates the cognitive complexity of the code and is a language independent complexity measure. Cognitive complexity plays an important role in understanding the fundamental characteristics of software, therefore directly affects the understandability and maintainability of software systems. The CWCM is theoretically evaluated against Weyuker's proposed set of measurement principles and is found to satisfy seven Weyuker's properties. The empirical validation and practical applicability of the proposed metric is evaluated by test cases, comparative study and through a framework.

The Complete Biometric System is a biometric facilitated third-party authentication system. It tries to address most of the major issues faced by current biometric industry. This paper describes a system that hides all the complexities of biometrics and provides biometric technology, vendor and platform independent authentication. It also introduces two new ideas: many-to-many mapping reduces the Total Cost of Ownership (TCO) while Device-Hierarchy implement in depth security. It achieves biometric vendor, technology and platform independence through the BioAPI specification (the Defacto standard for Biometrics). However it sets it sights far beyond the BioAPI. The system is able to overcome the issues relating to integration of biometrics in an enterprise level network which is one of the biggest problems faced by the biometric industry. It is also designed to provide a simple development environment that does not require complex data structures, pointers and memory management inherent to the BioAPI.

Mobile devices generates a call request message while initiating a call, which is then sent to a base station (BS). A BS processes a call request message and then takes a decision of acceptance or rejection for the call. It is important to analyze the total time, which includes the waiting time and the processing time, spent by a call request message in the system. For if, this time is greater than the permissible delay, call will be blocked. Hence, the quality of service is degraded which is not acceptable to the service providers. Further, failures (hardware and software related) and their recovery increase the delay. With this background, in this paper, we present queuing models for the analysis of delay experienced by a call request message for two cases: first, services of BS are not interrupted and second, services are interrupted due to the occurrence of failures at the BS. In the end, we discuss special cases of proposed queuing models based on the distribution of the processing times.

Geographic information system (GIS) analysis is used to help in rinding solutions for the most important geographical issues. Several programming techniques and methods are used to produce optimal solutions for GIS analysis. One of these techniques is the Solver in Microsoft Excel (MS Excel) which adjusts the values in the Excel sheet cells to produce an optimal result. Hybrid genetic algorithm (HGA) which is a combination of genetic algorithm and Hill-climbing technique is an important optimization method to solve many combinatorial problems such as GIS analysis problems. The solutions provided by HGA are better than the one obtained by any linear programming tool such as the Solver in MS Excel. The Solver produces one solution, which is most of the time not an optimal solution and leads to wrong GIS analysis. In order to prove this idea, several sites are selected as wildlife habitat locations in Lebanon using GIS analysis software, then HGA and the Solver are compared to find the maximum area for a wildlife habitat with the lowest cost of managing the habitat. This comparison proved that HGA finds many optimal solutions for wild life habitat locations better than the solution produced by MS Excel Solver. In addition, the cost provided by HGA is always similar or less than the cost of Solver solution.

To facilitate access to relevant documents and information has been the core of the library and information science (LIS) profession. In this regard tools like classification, cataloguing, and indexing formed the basis of library practice for a long time. These served particularly well for the material that was predominantly in the print form and required physical location for storage. New information sources, however, in contrast are increasingly in the electronic or digital form and stored on medium like computer hard disks requiring completely different strategy for access and management. Extension of the traditional bibliographic control tools as well as construction of new tools has therefore become pertinent. Ontology is one of the latest tools in this context. The paper discusses progress of information organising tools culminating in ontology, highlights the commonality of the concept of ontology and its applications among the fields of philosophy, computer science and LIS. It also discusses the select features of ontology development in practice and directions for features of ontology development in practice and directions for further work.

Wireless communication is the transfer of information over a distance without the use of wires. Wireless communication is generally considered to be a branch of telecommunications. Wireless operations permit services, such as long-range communications that are impossible or impractical to implement using wires. Wireless communication brings fundamental changes to data networking and telecommunications, and makes integrated networks a reality. Wireless networks focus on networking and user aspects. Network architecture for personal communication systems, wireless LANs, radio, tactical and other wireless networks, and design and analysis of protocols are addressed on a regular basis. At present, the major application of Wi-Fi implementation in libraries is limited to information management. This paper elaborates the Wi-Fi in detail about the components, functions, area of applications, issues, and challenges.

A disease-treatment ontology is being developed to model and represent treatment information found in medical abstracts. Treatment information extracted from medical abstracts and medical articles can then be encoded in this ontology and used for information retrieval, question-answering, summarisation and knowledge discovery. This paper explains the initial version of the ontology developed based on an analysis of 50 medical abstracts on colon cancer therapy retrieved from the Medline database. The ontology divides disease-treatment information into five classes-disease, treatment, condition, effect, and evidence. The sub-classes, properties and instances of these main classes are discussed with examples.

The present generation of computers is changing from single isolated devices to entry points into a worldwide network of information exchange. Therefore, support in the exchange of data, information, and knowledge is becoming the key issue in computer technology today. The increasing volume of data available on the Web makes information retrieval a tedious and difficult task. Researchers are now exploring the possibility of creating a semantic Web, in which meaning is made explicit, allowing machines to process and integrate Web resources intelligently. The vision of the semantic Web introduces the next generation of the Web by establishing a layer of machine-understandable data. The success of the semantic Web crucially depends on the easy creation, integration and use of semantic data, which will depend on building an ontology. This paper states the role of ontology in supporting information exchange process, particulary with semantic Web.

DESIDOC J Libr Inf Technol 2011, 31(2), 121-35.
Web resources have exploded in popularity and use and have lead to innovations in learning, teaching, clinical practice, and patient care. Availability of Web resources has changed what medical faculty and students actually read and use. However, little research has been done to find out medical faculty and students' perception about the Web resources in the medical college libraries. The main aim of this paper was to investigate the perception of Web as a learning resource by the faculty members and postgraduate students in medical college libraries of Coastal Karnataka. A questionnaire-based survey of six medical college libraries in Coastal Karnataka was conducted. The results show that respondents prefer using the Web more to the traditional library. They perceived that Web contains exhaustive knowledge and is easy to use.

Database mining is motivated by the decision support problem faced by most large retail organizations. Development of bar-code technology has made able retail organizations to collect and store massive amounts of sales data, referred to as the basket data. A record in such data typically consists of the transaction date and the items bought in the transaction. Very often, data records also contain customer-id, particularly when the purchase has been made using a credit card or a frequent-buyer card. A sequence database consists of sequences of ordered elements or events, recorded with or without a concrete notion of time. There are many applications involving sequence data. In this paper we have presented an application of data mining on shop database. This warehoused database is mined using PISA, which stands for Progressive mining of Sequential patterns algorithms whose results can be utilized for decision making.

According to research, it seems the existing 19th century educational institutions and the educational teaching and learning approaches may not be effective and enough for this 21st century global and digital society to bring about a meaningful learning environment. The author feels, keeping this aim in mind technology driven approaches have driven changes in the teaching and learning approaches. It seems to bring about a revolution in the way we learn and teach. In the author's opinion and experience, e-learning and innovations in educational technology would able to change the face of educational institutions in the years to come as can already be seen in this century. However, the author feels there are certain limitations in terms of infrastructure; teaching methodologies and access to innovative educational technologies which cannot be ignored. Is it the innovation in lectures or is it the technology driven educational approach responsible for pedagogical innovation seems to form the argument.
