This paper presents a proficient technique to test all static and dynamic analysis of chosen web application using state machine and variable chromosome length genetic algorithm. We propose a framework to generate user session based state machine model of dynamic behavior of a web application and the technique used to test the correctness of generated state machine is Variable chromosome length genetic algorithm. In this study, the author projected a new reflexive approach User Session based State Machine to test the dynamic content of a web application. This proposed technique will walk through various states of a highly dynamic web application, create a model of the active user session navigational paths and illustrate the dynamic content by means of a Finite State Machine (FSM). We applied Variable chromosome length genetic algorithm(VCL-GA) for generating test cases for proposed framework generated state machine. During test case generation we are refining test cases of generated state machine on progressive refinement manner using proposed VCL-GA. Finally the author depicts comparison of simple GA and variable chromosome length GA. Results shows that variable chromosome length GA gives efficient and better result on large state machine and especially in dynamic behaviors of application results are efficient.

The Wireless and the Mobile Networks appear to provide a wide range of applications. The achievement of the real world applications are attained through effective routing. The Intermittently Connected Mobile Network (ICMN) is a sparse network where a full connectivity is never possible. ICMN is a disconnected mobile network and is also a Delay Tolerant Network (DTN) that sustains for higher delays. The routing in a disseminated network is a difficult task. A new routing scheme called Bee Routing Protocol (BRP) is been proposed with a motto of achieving optimal result in delivering the data packet towards the destined node. BRP is proposed with the basis of Bee Colony Optimization technique (BCO). The routing in ICMN is done by means of Bee routing protocol. The efficiency of BRP is enchanted in contrast to existing Epidemic routing and Spray and Wait routing protocols. This paper captivates a novel routing methodology for data transmission in ICMN.
无线和移动网络似乎提供了广泛的应用。通过有效的路由可以实现实际应用。间歇连接移动网络(ICMN)是一种稀疏网络，永远不可能实现完全连接。ICMN是一种断开连接的移动网络，也是一种支持更高延迟的容忍延迟网络(Delay tolerance network, DTN)。分布式网络中的路由是一项艰巨的任务。提出了一种新的路由方案——蜂群路由协议(Bee routing Protocol, BRP)，其目标是在向目标节点发送数据包时达到最优结果。在蜂群优化技术(BCO)的基础上提出了BRP。ICMN中的路由是通过Bee路由协议实现的。与现有的Epidemic路由协议和Spray and Wait路由协议相比，BRP的效率更高。本文提出了一种新的ICMN数据传输路由方法。

A cochlear implant is a prosthetic device used to mimic the function of a cochlea in a person with profound and bilateral hearing loss caused by a damaged inner ear. The current work revolves around the design of real time channel vocoder based model of a cochlear implant in LabVIEW and the TMS320C6713 DSK. First, a uniform band 16-channel vocoder is designed for the analysis and synthesis of English vowels, where filters of 400 Hz bandwidth, with cut off frequencies up to 6200Hz are used, based on MATLAB analysis performed previously. To extend the analysis to words and sentences, short time features, namely, short time energy, short time zero crossing rate and main lobe width of the short time autocorrelation function, are extracted and Gaussian Mixture Modelling (GMM) is used to classify the speech segments as voiced or unvoiced. In an attempt to make the synthetic speech sound natural, the synthesis in the channel vocoder is done using a train of glottal pulses instead of a train of impulses. The intelligibility of the synthetic speech is measured by the Mean Opinion Score (MOS). For a channel vocoder where the synthesis section uses a train of glottal pulses, an MOS of 3.6 is obtained as against 3.5 when a train of impulses is used. The lab model of the cochlear implant, that is, the analysis section of the 16-channel vocoder is then realised in the TMS320C6713 DSK. Individual channel outputs are obtained by programming the DIP switches of the DSK and a DSK_AUDIO16_BASE, a 16-channel audio daughter card, is interfaced with the DSK to obtain the outputs from multiple channels simultaneously.

Pervasive computing provides an attractive visionfor the future. Mobile and stationary devices will dynamically connect and coordinate to seamlessly help people to implement their tasks. However, in reality still there are practices which require pervasive monitoring especially in the domain of geo vehicle monitoring. To make the vision of pervasive computing technologies for the geo vehicle monitoring we are integrating technologies like GPS (Global Positioning Technology), GSM (Global System for Mobile) for compaction monitoring. GPS is recently used for wide applications like orbit identification and positioning. GPS need some compatible receivers which support location-awareness using positioning technique like LBS (Location Based System). Soil compaction is a form of physical degradation resulting in densification and distortion of the soil where biological activity, porosity and permeability were reduced, soil strength is increased and soil structure partly destroyed. Monitoring the soil compaction manually in the workspace is not reliable and continuous monitoring by a single person may not be feasible. This would be the motivation to choose wireless communication. The compaction data and the location data will be sent to the server for remote monitoring. GSM will allow us to transmit the data to the remote server. The objective of this paper is to provide better accuracy with low cost GPS receiver's positioning results. This paper makes use of GPS, ARM7/TDMI (LPC2378) family and GSM. NMEA (National Marine Electronics Association) data acquisition from GPS is monitored. Compaction input is interfaced with GPS coordinates. Alerts can be sent from the vehicle to the user mobile phone through GSM communication using AT commands.

Orthopaedic problems have been a constant and nagging hindrance that has been plaguing the elderly community. The treatment for this requires either medication in hospital or at their home comfort by physiotherapists. The dearth of physiotherapists in India has compounded to this problem. Moreover, the media tools, that are employed to teach physiotherapy, have been found to be monotonous and non-interactive with the patients. In pursuit of finding a solution to this problem, a Physiotherapeutic Assistive Trainer (PAT) for elders using a Humanoid Robot, named Nao has been developed. Seamless interaction between Nao and the elderly patient is achieved using the Text-to-Speech module and sensors present in Nao. Further, it replaces human trainer by carefully monitoring the performance of the elders through the camera, equipped in Nao. The array of physiotherapeutic exercises executed by Nao is repeated when the patient make their request by touching Nao's tactile sensor. The performance of the limb and neck movement depicting the motion of Nao is analysed using ADAMS software. The reliability of the developed application is validated in a real-time environment. From the results obtained, it is inferred that the Humanoid Robot based Physiotherapeutic Trainer will be the scope of near future.

In the proposed technique, the first idea of a novel elucidation has been proposed to shelter dull Passport. The contemporary state of dull Passport be defeated by proper Passport verification along with Passport owner authentication. The proposed solution space ensures security against these two which is candidly adoptable in the current milieu of India. As Verification and Authentication are two special stream of Cryptography; the only way to lock facts, proposed contrivance is based on Visual Cryptography and Palm Vein based authentication practice. As a fact of multimedia data hiding, Visual Cryptography is a well-known method of encrypting images into several shares where stacking corresponding shares reveals secrets without intervention of any electronic devices. Palm Vein based biometric is already implemented for user authentication in many countries throughout the world. It is an on-going technology which is very easy to implement and cost effective with respect to resources and time. The said proposal will verify dull Passport through Visual Cryptography and authenticate dull Passport holder at various checkpoints through Palm Vein Authentication in the form of a Multilayer cryptographic technique. The performance of the proposed Visual Cryptographic algorithm is also compared with some existing algorithms. The comparisons shows that the proposed algorithm is better than the existing algorithms with respect to space requirement, Meaningfulness, and security.

The proposed reconfigurable architecture for Networks-on-chip (NoC) changes the network topology by dynamically changing the router connections. This ReNoC can adapt more than one application on a single chip for desired application known at runtime. The router connections are changed by using the configuration switches. This scenario gives the reconfigured NoC architecture and is achieved by data transmission between the source and destination of the NoC architecture. In this proposed reconfigurable NoC architecture, the energy consumption induced by the links is more than that of the router. So, data encoding and decoding t techniques are used to reduce the energy consumption of data transmission and hence the power dissipation in the NoC architecture.

The emergence of different wireless LAN technologies has called for the implementation of various services such as multimedia streaming over these networks. The use of Wireless LANs has changed from simple data transfer to transmission of delay sensitive and bandwidth intense applications like multimedia streaming. The provision of Quality of Service for multiple simultaneous users is a challenge. Multiple Descriptive Coding (MDC) allows to efficiently stream video over variable bit rate channel. In this paper, we use cross layer design with MDC to provide a solution to this challenge. By formulating the network functions such as encoder behavior and MAC scheduling in cross layers can be jointly optimized to provide the best video quality. Our Simulation results shows a improved PSNR, while maintaining upper bound on QoS parameter delay and jitter.

Given an input text, a text-to-speech (TTS) system is expected to produce a speech signal that is highly intelligible to human listener. State-of-the art synthesis approaches are: unit selection-based concatenative speech synthesis (USS) and hidden Markov model (HMM)-based speech synthesis (HTS). In USS approach, pre-recorded speech units are selected according to the given text and concatenated to produce synthetic speech whereas in HTS approach, features are extracted from the speech units and the context dependent HMMs are trained for these units. These models are concatenated to form sentence HMMs, which synthesize speech for the given text, by extracting features from them and passing it through corresponding source-system filters. For Indian languages, building a speech synthesizer for each language is laborious. In this work, monolingual and multilingual speech synthesizers are developed in the state-of-the-art approaches and the performances are compared for both the systems. Based on the acoustic similarities across Indian languages, a common phoneset and a question set is derived for four of the Indian languages namely, Tamil, Telugu, Malayalam, and Hindi. The performance of the synthesizers developed are evaluated using mean opinion score (MOS) derived from the listeners. The average MOS ranges from 2.57 to 3.88 for the monolingual and multilingual systems.

In the process of software development, testing is the critical activity which consumes more than 50% of resources and time. A challenging step in software testing process is to generate test cases that will sufficiently test the functionality of the software being developed. A technique commonly used to generate the test cases is through branch coverage. Even though the above technique successfully generates test cases for the input program, there are few limitations during which this technique does not prove to be useful. Especially when an infeasible path is encountered in the program under test, the test cases generated does not reflect the reality. To overcome such situation test cases generation through symbolic execution is proposed in this paper.

A challenging step in software testing process is to generate test cases that will sufficiently test the functionality of the software being developed. A technique commonly used to generate the test cases is through branch coverage. Even though the above technique successfully generates test cases for the input program, there are few limitations during which this technique does not prove to be useful. Especially when an infeasible path is encountered in the program under test, the test cases generated does not reflect the reality. To overcome such situation test cases generation through symbolic execution is proposed in this paper.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127279554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
