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.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"83 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":"122093428","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}

In VANET the vehicles are equipped with the On Board Unit (OBU) in which the developed application obtains the current location of the vehicle and makes updates in the location server and to the Road Side Unit (RSU). The location server is the centralized server that collects all the necessary information like position and the Id of the vehicles that are moving. The emergency vehicle obtains the location of the doctors' vehicle from the location server or from the RSU. Then, the communication phase is established between the vehicles which are based on the Vehicle to Vehicle communication (V2V) model where the vehicles behave as nodes. Thus, by identifying the location information about the vehicle, the privacy of the vehicle users may be revealed. To avoid the issues involved in the privacy of vehicles users, the authentication for the vehicle users has been introduced. The successful authentication preserves the privacy of the vehicle user and establishes the secure communication between the vehicles. The efficiency of the communication is increased by introducing the Trusted Authority (TA). The trusted authority module performs the segregation of sensitive and insensitive messages and only the sensitive messages are encrypted through the pairing technique in the communication phase. Thus, Trusted Authority increases the performance of communication in a secure way between vehicles in emergency situation. The proposed system increases the performance by 19% for 100 characters when compared to existing system.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"15 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":"134049574","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}

The Very High Throughput (VHT) of the order of Gbps can be achieved primarily with two important modifications when compared with the previous 802.11n standard. The first one is the increased number of spatial streams (8 as compared to 4 in 11n standard) and the second one is the support for multi user - multiple input multiple output (MU-MIMO). This paper places key discussions and simulation results pertaining to these two objectives. It also compares the performance of MU-MIMO and single user - multiple input multiple output (SU-MIMO) precoding techniques assuming perfect Channel State Information at the Transmitter (CSIT) for both high and low correlation channels. The paper also introduces a novel algorithm that optimizes the various precoding algorithms by reducing the computational calculations with the mathematical background for the capacity calculations. By analyzing the performances of various precoding schemes used for SU-MIMO and MU-MIMO, the mode switching SNR can be found out. This quantitative measure of SNR is certainly a powerful measure to choose between SU and MU-MIMO and also to serve all the users to the best possible extent. Also, estimation of the mode selection with very less computational effort highlights the advantages of the algorithm over the existing algorithms.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"1 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":"134002630","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}

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.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"39 6 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":"114741098","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}

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.

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.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"60 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":"124695702","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}
