Fuzzy techniques have demonstrated a surge in the practical applications of fuzzy set theory. Presents the speed control mechanism that solves the problem intelligently by learning, adaptation and incorporating human knowledge. The proposed speed controller is used to manage the speed of the trains while at the same time managing the uncertainty in the condition of railway tracks. To deal with the aforesaid issues of uncertainty a Fuzzy Inference System has been proposed. This helps in maintaining the optimum speed of railway vehicles, based on some rules derived from expert knowledge. The proposed system has been aided by some active agents such as environment monitoring and time scheduling that minimizes the risk of undesired circumstances. This paper presents the simulated form of a vehicle control system, which is controlling speed by controlling vehicle deviation index, channelizing the traffic and maintaining track condition. Designing of Fuzzy Inference Systems for this speed controller is based on fuzzy set theory and it requires the computation to be carried out in real time.

CPU scheduling is a fundamental function of operating system. The performance and efficiency of multitasking operating systems mainly depend upon the uses of CPU scheduling algorithm. When an operating system wants to execute a process, it does not know the execution time it needs. After running, the exact execution time of that process would appear. Here we present a new scheduling approach using the Partitioning Around Medoid (PAM) clustering algorithm in conjunction with Shortest Job First (SJF). This proposed approach is able to estimate the execution time (next CPU-burst time) of a process. The processes in each cluster are processed in the ready queue, for the time period of one time quantum, equal to medoid of respective cluster. The remaining processes, which are not completely processed in first cycle, are clustered again with remaining burst time and time quantum equal to medoid is assigned to the processes in respective clusters. This process continues until there is no process in the ready queue.

Mobile phones are small, compact, easy to use and have become an essential part of life for many people. It enables people to maintain contact with family, friends and business associates. As well as the general communication benefits, access to a mobile phone also provides safety benefits by enabling people to alert breakdown or emergency services when necessary. Talking on the phone and sending text messages while driving are obvious distractions that can lead to fatal accidents on the road. According to Indian National Crime Records Bureau at least 13 people die every hour in road accidents. Various Statistics also reveal that a large portion of road accidents in India is caused by mobile phone usage while driving. Though various measures and rules placed on mobile phone usage, still it's highly impossible to prevent this type of occurrence. So in order to overcome this serious issue, authors developed an application which will helps in reducing the number of mobile accident significantly and further extend the research, by comparing the results obtained after installing this application with recent study of US National Safety Council, conducted on 2010.

People in the developing countries always face the problem of internet; the major problem is that if a connection of internet is based upon LAN and Wireless, then it is not possible to use both connections at the same time. The operating system (OS) allows only one connection at a time. So, designing a software is the solution to solve this problem (software is designed only for internet browsers because basic requirement of Internet is only web surfing), which will be able to connect internet browsers to the required connection. It will work as a medium between the browser and the connection. The software is designed to use all available connections at one time, not for increasing the speed of internet. All possibilities of connections are included in the software, e.g., Bluetooth, LAN, Wireless, USB modem, USB phone modem, etc. Basically, the algorithm is designed in Microsoft Visual Studio 8.0 software.

Object-Oriented approach is considered superior than traditional structured approach. There are several benefits of this approach over structured approach. Even then it cannot be said that a system developed using this approach will have all the qualities that are expected. One of the expected qualities of a software system is testability. It is always required to improve testability. During development of object-oriented software there are many places where natural language is used. There are several drawbacks of natural language. In this paper, we try to find impact of some of these drawbacks (noise, silence, over-specification, contradiction, ambiguous, forward reference, dilemma, inconsistent-vocabulary and non-clarity) on testability (unit, integration, system) of the system. This work will help developers to improve testability of an object-oriented software system by concentrating the affects of drawbacks of natural language on testability.

Int J Geomatics Geosci 2012, 3(1), 121-33.
Leptospirosis epidemiology Information sharing is important for the shared preparation, response, and recovery stages of sickness control. Leptospirosis epidemiology phenomena are powerfully associated with spatial and temporal factors. Online web GIS-based service provides a real-time and dynamic leptospirosis epidemiology way to represent leptospirosis epidemiology information on maps. Nevertheless, data integration, interoperability, and cartographic representation are still major challenges in the health geographical fields. These challenges cause and effect obstacles to sharing health information and stifle the success in understanding and responding to disease and epidemiology. To endeavor these challenges in leptospirosis epidemiology data mapping and sharing, the authors have designed Interoperability through Service Oriented Architectures(SOAs). Based on the Open Geospatial Consortium (OGC) and Free Open Source Software (FOSS) specifications to share spatial-temporal leptospirosis epidemiology information.

Changes in intonation patterns may convey not only different meaning, but also different emotions even if the sequence of speech segments is the same in a sentence. The patterns change depending upon the structure and emotion of the sentence and require being stored in speech database. It is a difficult and time-consuming task to store all utterances of all the expressive style, which also consumes huge memory space. Therefore, there should be an approach that minimizes the time and memory space for emotion-rich database. A number of studies in this respect have been carried out for several languages and models developed. However, for Hindi not many studies have been carried out. Taking this fact into consideration, the intonation patterns have been studied and analysed for Hindi language and compared with some other languages. On the basis of the analysis on intonation patterns, an algorithm has been proposed for emotion conversion. This algorithm requires storing of neutral utterances only in the database and other expressive style utterances can be derived from these neutral utterances. The proposed algorithm is based on the linear modification model, where fundamental frequency is a major factor to convert emotions. In this paper, surprise, sadness, happiness, and anger are taken as target emotions. For performing experiments and verification of results, an emotion-rich speech database is prepared with the help of 15 native speakers. Each speaker has been given 20 sentences and asked to generate utterances in five expressive states "neutral", "sadness", "anger", "surprise", and "happiness". These sentences are recorded in normal laboratory conditions with a 44.1 KHz sampling rate and 16-bit precision with mono channel. In the perception test, group of listeners were asked to listen to the utterances from database and judge the emotion. This perception test involves classification of the emotions already available in the database by the listener and to judge the quality of converted neutral utterances. The results are analysed and performance of the experiment is evaluated. The accuracy of the perception test on transformed emotions was found out to be 93.2% for surprise, 91.6% for sadness, 83% for happiness, and 95.3% for anger.

Retrieval of domain-specific images is an important research area. Morphological skull stripping and segmentation is proposed for highlighting and extraction of the region-based features of human brain T2-weighted magnetic resonance (MR) images. Further, fuzzy representation of these features and its use in retrieval of brain MR imaging (MRI) is demonstrated in this paper. Unified Fuzzy Matching technique is used to assess the image-to-image similarity of MRI. Segmentation results show a marked improvement in the quality of segmentation as compared to fuzzy c-means clustering method and it is confirmed with manual segmentation. Further, the use of features obtained with this technique in retrieval has also been found to give better retrieval results in terms of precision, average rank and mean standard deviation. Such brain MRI retrieval system is useful tool to assist doctors in diagnosis by quickly searching similar cases in this domain.

In computer vision, the corners of an object play an important role in shape representation and analysis. In this paper, we carried out a dozen popular and most cited corner detection algorithms and studied their performances based on several performance measures proposed by us as well as in the literature over a varied range of images and categorized the corner detectors based on different image types and rank their performances with suitable threshold ranges corresponding to different image types. After obtaining a suitable corner detector for a given type of images, the paper describes a new approach to corner detection in a digital image based on the assumption that corners are those image points with high information content, and hence corners in an image exist in those regions having considerably high-intensity variation. Consequently, a complex corner response function is computed only within those regions with considerable high-intensity variation instead of entire image, reducing the computational cost of the whole procedure. Experiments conducted with the help of a few images showed the efficiency of the technique, both in terms of execution time and false-positive corners.

Recently, in the smartcard-based authentication system, there is an increasing trend of using fingerprint for the card holder verification, instead of passwords. However, the security of the fingerprint data is particularly important as the possible compromise of the data will be permanent. In order to protect the fingerprint data, the fuzzy vault scheme has emerged as a promising solution to the user privacy problem. The techniques, such as "fuzzy vault," which is based on the difficulty of the polynomial reconstruction need to be developed for the smartcard-based environment. Proposes a secure and efficient approach, which reconstructs a polynomial on a smartcard with the aid of a server by using fuzzy fingerprint vaults distributed into the smartcard and the server. The goal of the approach is, under the real-time constraint, to enhance the security level of the fuzzy vault scheme against not only the typical brute-force attack, but recently reported correlation attack which finds the real minutiae using multiple fuzzy vaults enrolled for different applications. Based on the experimental results, we confirmed that our secret distribution-based approach can perform the fuzzy vault-based fingerprint verification more securely (by a factor of 177 in brute-force attack, and by a factor of 109 in correlation attack) and quickly (by a factor of 17) on a combination of a smartcard and a server.

Approach for a biometric cryptosystem based on keystroke dynamics and the k-medoids algorithm is proposed. The stages that comprise the approach are training enrollment and user verification. The proposed approach is able to verify the identity of individuals offline avoiding the use of a centralized database. The approach as reported in this paper may be implemented in stand-alone terminals or embedded in password-based systems to increase the security. The performance of the proposed approach is assessed using 20 samples of keystroke dynamics from 20 different users. Simulation results show a false acceptance rate of 2.89% and a false rejection rate of 3.35%. The cryptographic key released by the proposed architecture may be used in several potential applications such as user login, file encryption or even portable authentication to gain access to virtual private networks.

There are some networks called "Anonymizing networks" which allow users to gain access to internet services without revealing their identity (IP-addresses) to the servers. Networks such as "Tor (The Onion Router)","Crowds" and "I2P" gained popularity in the years 2002-2007, but the success of such networks however has been limited by users employing this anonymity for abusive purposes such as defacing popular websites such as "Wikipedia". Website Administrators blocks entire network which is connected to the abusive system to get rid of the abuser. Hence, well-behaved users also get blocked due to this action. To address this problem, authors present a Nymble system in which servers can "blacklist" mischievous users without affecting good users and also maintaining anonymity across the network.

Large system like e-college time table retrieval systems with web accesses are difficult to develop due to their complex and immobility nature. The Service oriented architecture (SOA) facilitates the development of such systems by supporting modular design, application integration and inter operation and software reuse. With open standards, such as XML, SOAP, WSDL and UDDI, the SOA supports interoperability between services operating on different platforms and between applications implemented in different programming languages. An e-college time table retrieval model that uses the service oriented architecture as a basis for designing, implementing, deploying, invoking and managing college services is described. The e-college time table retrieval model that is developed provides support for staffs, HODs, Principal, Directors and other societies interested in e-college time table retrieval systems, as well as for students. This system provides the facility for coordinator to enter the time table or change the time table and the staffs to access the time table using their PDAs or by using their smart phones. They can get the alerts about their duties over the mobiles and exchanging of duties can also be done using the mobile devices with the help of web services. Multimedia input and output, with text, images and speech, make the system more user friendly than existing e-college time table systems.

Performance of the computer has increased in recent years, so the communication subsystems have become the main problem within the system. So, the switch based interconnection networks are used in the current high performance systems to solve this problem. To solve this problem, whenever the topological change occurs, the connectivity between the network devices must be re-established by the management mechanism. The reduction in the performance of the network occurs during updation of the routing table, which becomes the main challenge in the network reconfiguration. Authors propose the reconfiguration method that does not stop the packets injection during the reconfiguration process. In this scheme no extra additional network are required.

Websites have been used as important media for education, marketing and sales in different domains, and their effectiveness highly depends on their usability. Hence, website usability has been the focus of much contemporary research. To characterize and ensure website usability, international standards and guidelines have been developed. However, usability also has a culture-related nature. The purpose of this study is to compare the usability of websites as defined by international standards on the one hand, with usability as perceived by Iranian end-users on the other hand. To this end, we extract the common key factors of two sets of international usability standards, namely, ISO 9241-151:2008(E) and HHS 2006 guidelines developed by U.S. Department of Health and Human Services and measure the usability of two university websites. Then, we compare the outcome with the perception of a sample group of Iranian users by means of a usability questionnaire. Study provides us with two major outcomes: firstly, there is a meaningful difference between the usability score given based on the guidelines and the perceived usability by Iranian users due to culturally steered factors. Secondly, the usability factors and the priorities set by the international guidelines are not irrelevant to the preferences of Iranian users but they only partially reflect local users' interests. In conclusion, in order to improve website usability for local users, international standards can be adopted, but they should be adapted and prioritized according to local cultural preferences.

Dramatic increase of internet users and development of new high volume internet applications has a profound impact on design of next generation passive optical network (NG-PON). Today, most of the available networks are quite busy networks and as the number of nodes increases in the network, the communication over the network also increases. A reliable end packet delivery is always one of the basic requirements of a user as well as network. When the data is transferred over the network there are many major causes that can result packet loss, such as congestion over the network. Any kind of active or the passive attack over the network can make packet loss while transferring the data and also, heavy traffic over any network gives the problems like congestion, degradation in throughput. The Passive Optical Network (PON) and Gigabit Passive Optical Network (GPON) resolve most of the above defined problem. As it provide such a large bandwidth that it will never gives efficiency problem in a network. PON also resolve the bottleneck problem along with delay analysis over bottleneck congested network.

Situation where in people are not able to access the various basic financial services /products such as saving loan, remittances etc from formal financial institution is known as 'Financial exclusion' the reason for the same could be anything like distance from the bank branch, branch timing, difficult physical access, low income/assets, ease of availability of informal credit, gender, illiteracy, documentation process at bank branch, etc. This situation could result in various economical and social undesirable consequences and ultimately lead to social exclusion, therefore, for peaceful and happy living of a society, social inclusion is must and first step towards this, is financial inclusion. There for financial inclusion is the key to sustain equitable growth. Accesses to financial services will provide the un-banked and poor people an opportunity to built saving, make investment, avail credit etc. also such access help them to ensure themselves against income shocks and equip them to meet emergencies such as, illness, death in family or loss of employment; also it protects the poor from the clutches of the injurious money lenders, thus issue before policy makers was how to provide comfortable access to financial services in un-banked areas. To resolve RBI had come out with frame work, permitting intermediaries known as Business correspondent / Business Facilitator for providing financial services to the un-banked areas on behalf of the banks using I.T. as the facilitator between customer, BC/BF and bank so as to ensure transparency, control and confidence in the system. The objective of the study is to know and understand how Information Technology can helps in implementing the Financial Inclusion activity.
