With the help of the receiver in a moving vehicle, dynamic data is logged continuously in IRNSS/ NavIC+GPS hybrid operation to get receiver’s coordinates, Geometric dilution of precision (GDOP) and receiver’s velocity. The logged values of receiver’s coordinate contain errors, which is minimized first considering Satellite Selection Algorithm (SSA) based on GDOP values and then by applying PSO based algorithm to reduce Doppler shift effect and receiver’s clock offset. After improvement of dynamic receiver’s coordinates for each observation, velocity of receiver is calculated. Results show that velocity obtained using this estimation technique is more accurate in comparison to the velocity information provided by the IGS receiver. This finds major applications in real time vehicle tracking for various applications. In addition, atmospheric delays are expressed here in terms of Doppler shift.","PeriodicalId":261794,"journal":{"name":"2020 IEEE International Conference on Electronics, Computing and Communication Technologies (CONECCT)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131910526","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 atmospheric CO2 concentration is measured as continuous swaths of the parallelogram footprints which are available as the Level-2 samples with a swath width of 10.3 km approximately. The temporal frequency of the retrieval at one place is 16 days approximately. This work attempts to forecast the OCO-2 samples at an interannual time scale from the available past samples at the nearby locations using geostatistical spatiotemporal kriging-based mapping approaches. This forecasting is needed to understand the future seasonal behavior of CO2 beforehand. For the validation, we have used the XCO2 swaths of OCO-2 in a study region from 2015 - 2019 and foretasted in the year of 2018 and 2019. One of the variant approaches found to produce 1.52 ppm root mean square error (RMSE), which is a good result with limited samples. This approach is capable of spatio-temporal prediction and forecasting of other products of OCO-2 and might be improved further by considering correlated auxiliary variables in the study region.","PeriodicalId":261794,"journal":{"name":"2020 IEEE International Conference on Electronics, Computing and Communication Technologies (CONECCT)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131793053","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}

GPU SW programming models such as OpenGL have evolved over decades to cater to the unique mixed pipeline 3D GPU architectures. Due to the sticky nature of GPU SW programming model, leveraging other HW blocks to enhance graphics performance has been a most challenging task for SW architects. System designers have usually responded to the GFLOPS demand by increasing the GPU HW specifications. This paper proposes enhancing GPU performance by leveraging DSP transparently in background without impacting GPU software programming model. The proposed solution consists of multiple novel techniques namely ability to offload vertex shader to DSP, 3 stage pipelined execution and ability to re-use GPU internal pipeline. The proposed solution is prototyped in Jacinoto6 Platform from Texas Instruments. The default GPU spec performance is increased by up-to 41% by leveraging dual core C66x DSP in Jacinto6 Platform using proposed solution for different use-cases. The proposed solution is fully transparent to application software stack. In addition, the solution is directly applicable to any GPU + DSP architecture making it attractive approach for cost optimized solutions.","PeriodicalId":261794,"journal":{"name":"2020 IEEE International Conference on Electronics, Computing and Communication Technologies (CONECCT)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128327215","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}

With the paradigm shift toward Service Oriented Architecture, Service computing has become quite predominant across the globe. Web service discovery is not just important but also crucial and cumbersome. This paper proposes a new web service discovery approach that is semantics aware. This approach helps to extract the underlying semantics and enables users to utilize web services. The strategy focuses on the creation of a web database comprising of dataset crawled from well-known registry sites. A word-level semantics is applied using clustering based on the NPMI value. The library creation happens based on the semantic similarity values. An ontology for the principal classes of web services is modeled to facilitate clustering based on the initial aggregation of the data and the concepts. Finally, a web service discovery approach is designed that furnished related web services based on user queries. The proposed strategy yields an accuracy of 90.4 % which is much better than the existing approaches.","PeriodicalId":261794,"journal":{"name":"2020 IEEE International Conference on Electronics, Computing and Communication Technologies (CONECCT)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130454599","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}

Several empirical machine-learning models, such as linear models, non-linear models, probabilistic models, tree-based models and, neural networks, are used for performance prediction. Furthermore, the prediction model’s accuracy may vary depending on performance data gathered for different software types (compute-bound, memory-bound) and different hardware (simulation-based or physical systems). We have examined fourteen machine-learning models on simulation-based hardware and physical systems by executing several benchmark programs with different computation and data access patterns. Our results show that the tree-based machine-learning models outperform all other models with median absolute percentage error (MedAPE) of less than 5% followed by bagging and boosting models that help to improve weak learners. We have also observed that prediction accuracy is higher on simulation-based hardware due to its deterministic nature as compared to physical systems. Moreover, in physical systems, the prediction accuracy of memory-bound algorithms is higher as compared to compute-bound algorithms due to manufacturer variability in processors.","PeriodicalId":261794,"journal":{"name":"2020 IEEE International Conference on Electronics, Computing and Communication Technologies (CONECCT)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124596689","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 functional waves generated in terms of bio-magnetic field due to cardiac impulses can be investigated using Magnetocardiogram. The challenging task in the research is to image/localize the cardiac dysfunctions from MCG not only at the body surface but also to reconstruct the activities on the myocardial level. In order to solve this, one has to model a generic structure of the heart enclosed within a thorax with MCG sensors called as Forward problem.We proposed a novel approach in the construction of the spatial matrix derived from the vectorcardiography signals. The forward matrix was then used to estimate the position, orientation and the cardiac activities. The forward and inverse methods were applied to normal and myocardial infarcted cases for single and distributed source models. The localization accuracies of the proposed model based on VCG lied in the range of 0.01mm to 1 mm.The cardiac activities were estimated and compared using L2 norm and L1 norm regularization techniques. According to this study, the proposed spatial matrix used in the inverse problem gave good localization and L1 norm regularization provided sharper solutions than L2 norm.","PeriodicalId":261794,"journal":{"name":"2020 IEEE International Conference on Electronics, Computing and Communication Technologies (CONECCT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130670232","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}
