Entire radiological datasets are classified, leading to a meaningful morphological interpretation, clearly distinguishing pathologies. After standard pre-processing, e.g. smoothing the input image data, the entire volume is partitioned into a large number of sub-regions utilizing watershed transform. These fragments are atomic and fused together building contiguous structures representing organs and typical morphology. This fusion is driven by similarity of regions. The relevant similarity measures respond to statistical a-priori models, derived from training datasets. In this work, the applicability of evolution strategy as classifier for a generic image segmentation approach is evaluated. Furthermore, it is analyzed if accuracy and robustness of the segmentation are improved by incorporation of meta features evaluated on the entire classification solution besides local features evaluated for the pre-fragmented regions to classify. The proposed generic strategy has a high potential in new segmentation domains, relying only on a small set of reference segmentations, as evaluated for different imaging modalities and diagnostic domains, such as brain MRI or abdominal CT. Comparison with results from other machine learning approaches, e.g. neural networks or genetic programming, proves that the newly developed evolution strategy is highly applicable for this classification domain and can best incorporate meta features for evaluation of solution fitness.","PeriodicalId":410045,"journal":{"name":"2015 International Conference on Computing and Communications Technologies (ICCCT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132287001","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 network due to mobility nodes are moving randomly, resulting in topology change. This topology change leads to frequent breakage of link. To repair the broken link AODV and DSR uses broadcasting mechanism. Broadcasting floods control packets. Flooding results in congestion due to limited buffer space, bandwidth, and battery power of mobile nodes. Congestion leads to dropping of packets resulting in decrease of network performance. Congestion can be avoided if the numbers of control packets are reduced. In this paper a new algorithm is proposed which avoid the congestion and repair the broken link by choosing a set of limited nodes for alternate route based on the quadrant position, battery status, queue length, and forwarding region. The proposed solution is termed as Improved Optimum Angle Selection AODV (IOAS-AODV) routing algorithm. This proposed solution is implemented, tested and the performance is analyzed. From the results it is observed that the proposed solution improves the routing performance such as throughput, end to end delay, routing overhead, and packet delivery ratio.","PeriodicalId":410045,"journal":{"name":"2015 International Conference on Computing and Communications Technologies (ICCCT)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133611558","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 implementation of MIMO detection becomes a difficult task as the computational complexity increases with the number of transmitting antenna and constellation size increases. The decoder for a 4*4 MIMO system with 16-QAM modulation and spatial multiplexing is implemented using Matlab. Difficult part is MIMO detection; ML decoding cannot be implemented directly because increase the complexity exponentially if size of constellation and number of transmit antenna increases. Sphere decoding reduce the complexity of decoding with some improvement with the decoding rate and BER. In my project sphere decoding combined with single tree search and ML decoding greatly improve the decoding Rate and BER. In sphere decoding selecting the sphere radius is very important. Sphere decoding algorithm implemented in the tree search complexity of algorithm is more reduced. In tree search Tree pruning strategies are used to reduce the more difficulty in the tree search based algorithms. The basic idea is to reduce the number of tree nodes visited to achieve a ML result. The decision where to visit a node or prune it is based on its Partial Euclidean Distance(PED). Depending upon tree pruning strategy the algorithm achieve optimal BER.","PeriodicalId":410045,"journal":{"name":"2015 International Conference on Computing and Communications Technologies (ICCCT)","volume":"219 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124008096","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}

Clustering can be made effective in CEAACK MANETs by opting for a cluster head mechanism which ensures that control rests with a single powerful node within a cluster. This cluster head takes on the responsibility of routing the packets efficiently by coordinating with the base station. Cluster heads are also prone to malicious attacks and is affected more than a normal network. In this paper we try to incorporate a new approach in CEAACK MANETs by implementing a cryptographic technique to tackle the vulnerabilities of the network. This cryptographic is highly secure which uses a distinct classified digital key which can be generated dynamically using the Advanced Encryption Standard(AES) Algorithm. This technique can ensure that data is securely transmitted in a reliable manner. This scheme aims at transmission efficiency and also tries to reduce the intrudes in CEAACK MANETs.","PeriodicalId":410045,"journal":{"name":"2015 International Conference on Computing and Communications Technologies (ICCCT)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134637958","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}
