This paper proposes a highly secure method to hide the secret messages to prevent unauthorized access. The proposed method works in three levels. Single level of encryption and two levels of steganography are used. First level makes use of a DNA based playfair encryption. Second level hides the encrypted secret file in a randomly generated DNA sequence. In the third level, embedded DNA is hidden in an audio file. The main objective of the proposed method is that no one could be able to find the existence of the secret file.","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":"130727641","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}

Among perfect reconstruction (PR) and Nearly Perfect Reconstruction (NPR) filter banks, the later is preferred since the filter banks can be realized with minimal complexity. In this paper, a prototype filter is designed using the windowing techniques and the pass-band edge frequency (ωp) is optimized using the linear optimization technique for the design of a near perfect reconstructed filter bank. Among the different windowing techniques, Kaiser and dolph-chebyshev windows have been considered. The performance of the filter banks for each of these windowing techniques was measured in terms of Peak Reconstruction Error (PRE). These techniques are being applied on an Electro Cardio Gram (ECG) signal and their respective results are also being discussed.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"21 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":"134229164","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}

Following these, the Mobile Ad hoc Networks (MANET) aid in wide development of many applications. The achievement of the real world applications are attained through effective routing. The Intermittently Connected Mobile Ad hoc Network (ICMANET) is a sparse network where a full connectivity is never possible. ICMANET is a disconnected MANET 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 A-Routing (AR) is been proposed with a motto of achieving optimal result in delivering the data packet towards the destined node. A-Routing is proposed with the basis of Ant Colony Optimization technique (ACO). The routing in ICMNAET is done by means of Ant routing protocol. This paper enchants a novel routing methodology for data transmission in ICMANET.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"124 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":"133304801","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}

Relevant next-generation wireless-based indoor services are required to support multi-gigabit information transfer rates. As such, the associated electromagnetic (EM) spectral needs warrant accommodating almost unlimited wireless channels each shouldering enormous bandwidth. Relevant wireless transport requirements can be met with the span of EM spectra that currently remain unclaimed and unregulated. They exist as prospective resources in the frontiers of mm-wave range (spanning 30 GHz to terahertz band). Addressed in this study thereof is the feasibility of conceiving “inferential prototypes” of RF channel-models in the 30+ GHz through THz spectrum of indoor ambient by judiciously sharing the “similarity” of details pertinent to already existing (known) “models” of traditional, lower-side EM spectrum, (namely, VLF through micro-/mm-wave); and, an approach based on the principle of similitude due to Edgar Buckingham is invoked toward model-to-(inferential) prototype transformations. Examples on indoor path-loss estimation for line-of-sight (LoS) case is presented for the spectral range of interest and the efficacy of the proposal is outlined.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"13 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":"133854205","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 typical lexical matching technique works by matching the sequence of tokens between the texts to recognize paraphrases, and fails when different words are used to convey the same meaning. We can improve this simple method by combining lexical with syntactic or semantic representations of the input texts. The present work makes use of syntactical information in the texts and computes the similarity between them using word similarity measures based on WordNet and lexical databases. The texts are converted into a unified semantic structural model through which the semantic similarity of the texts is obtained. An approach is presented to assess the semantic similarity and the results of applying this approach is evaluated using the Microsoft Research Paraphrase (MSRP) Corpus.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"26 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":"114712036","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 great challenge of the information retrieval system is to retrieve the related relevant information from the heterogeneous web resources. This paper aims for the retrieval of the relevant geo-spatial concepts from the geo-spatial ontology which aids application in quality testing of water and flood prediction. In the geo-spatial concept space, the retrieval of relevant geo-spatial concepts depends on the distance separating the two geo-spatial concepts and the context of the concepts. Research in geo-spatial information retrieval has used either the semantic distance between the geo-spatial concepts or the context of the concepts for computing the relevancy. This paper proposes HCC (Hybrid Conceptual Context) algorithm which aims at retrieving relevant geo-spatial concepts by considering both the semantic distance and the context on which the concepts occur in the geo-spatial space. This work computes the semantic similarity by measuring the semantic distance using Euclidean and Manhattan distance measure. This computation is carried out in two steps such as retrieval of semantically similar geo-spatial concepts and the retrieval of context dependent geo-spatial concepts. Semantic similarity computation in HCC algorithm retrieves contextually and semantically similar relevant geo-spatial concepts using Euclidean distance and Manhattan distance measures. Experiments have been done using Ordnance Survey Master Map datasource and geo-spatial ontology. The precision and recall show Manhattan based semantic similarity computation improves relevancy by 10%.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"125 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":"114594229","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 proposed Efficient Dynamic Traffic Control System (EDTCS) has Traffic Control Unit (TCU), Monitor Unit (MU) and Road Side Unit (RSU). RSU contains RFID reader which reads the unique RFID code for an emergency vehicle and send it to MU. MU uses sensors such as proximity switch and RFID tags to get the count of normal and emergency vehicles respectively and sensed information is sent to TCU. TCU receives the count of normal and emergency vehicles and changes the signal dynamically by comparing the count obtained from different lanes. The proposed EDTCS saves travel time and gives a special priority to emergency vehicles like ambulance.","PeriodicalId":113531,"journal":{"name":"2013 International Conference on Recent Trends in Information Technology (ICRTIT)","volume":"1991 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":"125518179","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}
