Improved trilateration for indoor localization: Neural network and centroid-based approach

[EN] Location awareness is the key to success to many location-based services applications such as indoor navigation, elderly tracking, emergency management, and so on. Trilateration-based localization using received signal strength measurements is widely used in wireless sensor network-based localization and tracking systems due to its simplicity and low computational cost. However, localization accuracy obtained with the trilateration technique is generally very poor because of fluctuating nature of received signal strength measurements. The reason behind such notorious behavior of received signal strength is dynamicity in target motion and surrounding environment. In addition, the significant localization error is induced during each iteration step during trilateration, which gets propagated in the next iterations. To address this problem, this article presents an improved trilateration-based architecture named Trilateration Centroid Generalized Regression Neural Network. The proposed Trilateration Centroid Generalized Regression Neural Network-based localization algorithm inherits the simplicity and efficiency of three concepts namely trilateration, centroid, and Generalized Regression Neural Network. The extensive simulation results indicate that the proposed Trilateration Centroid Generalized Regression Neural Network algorithm demonstrates superior localization performance as compared to trilateration, and Generalized Regression Neural Network algorithm.Jondhale, SR.; Jondhale, AS.; Deshpande, PS.; Lloret, J.

THE COMPARATIVE STUDY OF ADRAKADI QUATH SIDHA DUGDHA AND ASHWAGANDHA CHURNA IN THE MANAGEMENT OF ARSHAS (HEMORRHOIDS)

Arshas (hemorrhoids) occurs mainly due to the vitiation of Agni, which leads to Malavasthambha (constipation) and Vimarga gamana of Apana Vayu. So obviously, the drug, which has capacity to streamline the vitiated Agni and regulate the Anulomagati of Apana Vayu, will be the drug of choice in treating Arshas. Adrakadi quath sidha dugdha possesses Ushna, Tikshna Dipana, Pachana and Vatanulomana property. Envisaging these points an attempt has been put forth to evaluate the efficacy of Adrakadi quath sidha dugdha in patients suffering from Arshas and the subject entitled The Comparative study of Adrakadi quath sidha dugdha and Ashwagandha churna in the management of Arshas w.s.r. to hemorrhoids have been selected for study. Total 60 patients of Arshas were registered for the present study. The selected patients were distributed randomly into two groups. Group A: 30 patients were treated with Adrakadi quath sidha dugdha 40 ml twice a day with water, after food for 15 days. Group B: 30 patients were treated with Ashwagandha churna 2 gm twice a day with water for 15 days. The observations and results obtained from clinical study have been analysed statistically to evaluate the significance of the curative properties of therapies

Clinical profile of maternal deaths due to postpartum haemorrhage

Background: Postpartum haemorrhage is one of the dreadful complications that occur during delivery. It is often un-anticipated and occurs suddenly and un-expectedly. It is responsible for 20 percent of maternal deaths in developing countries. These deaths are largely preventable. The objective of the study was to find out the clinical profile, associated co-morbid conditions and contributory factors and treatment modalities used in the management.Methods: Retrospective observational study of maternal deaths due to postpartum haemorrhage (PPH) was carried out at tertiary care hospital. The data of maternal deaths for seven years from year 2013 to 2019 was reviewed, compiled and analyzed to draw conclusions.Results: There were 18 maternal deaths (19%) due to PPH out of total 86 maternal deaths. The average age of the woman who died due to PPH was 24 years. Ninety five percent of the cases of PPH were due to atonic uterus. Seventy percent of the cases had reported in advanced stage of shock with average blood loss of more than two to three litres. Poor general condition due to delay in reaching to tertiary care hospital was predominant feature. Sixty percent women underwent obstetric hysterectomy. Massive blood transfusion was given in fifty percent cases. Severe pregnancy induced hypertension, severe anaemia and severe concealed accidental haemorrhage were common associated factors in sixty percent of maternal deaths.Conclusions: Postpartum haemorrhage is still a common cause of maternal death. Early detection, prompt aggressive management, adequate blood replacement, use of uterine balloon tamponade and non-pneumatic anti-shock garment, timely transfer to higher centre and timely decision for surgical interventions can prevent maternal deaths

WEBO-KIT: AN ENHANCED WEB UI TOOLKIT

Designing UI and backend are one of the main aspects of Web application development. Developers waste a lot time in designing tool like tree view, grid view etc. one by one whenever required as per the requirements of application. Solution to these problems are building UI toolkit library containing commonly required tools, include that library and drag-drop the tool while building application. The existing UI toolkits have less number of tools and do not contain each and every tool, have a lot of ambiguities in their behaviour pattern, look-feel, large in size and have cross browsing problem. There is a need of powerful UI toolkit which will have all necessary tools, consistent behaviour pattern and light in weight. If we compare same tool from different libraries, they may have different properties which can be combined under one library as a feature rich library. Our objective is to combine all the properties of a tool from different available web UI toolkits like kendo, dojo, jQuery UI, YUI etc., providing consistent behaviour pattern, look-feel, cross browser support, add new features and light in weight. On the basis of analysis done on various available toolkits, feature rich and configurable library of commonly used tools is being created

Heat transfer during multiple jet impingement on the top surface of hot rolled steel strip

The cooling which occurs on the runout table (ROT) is a key processing step for hot rolled steel strip. It determines the final microstructure and thus mechanical properties as well as flatness of the hot band. The use of multiple jets during ROT cooling results in interactions between neighboring water jets which can affect the overall heat transfer rate. The heat transfer which takes place during cooling with multiple jets is fairly complex and the available knowledge is limited. The research work described was done to obtain an understanding of the effect of varying nozzle-to-nozzle distance, plate speed and flow rate of the impinging water on the heat transfer taking place on the ROT. Experiments were performed on the pilot scale runout table available at UBC, using instrumented test samples of steel. Each sample was instrumented with twenty thermocouples which measured the internal thermal history. This data was then used in conjunction with an Inverse Heat Conduction (IHC) model to calculate surface heat fluxes and temperatures. Some of the variables examined included: speed of movement of the test plate (0.22 m/s and 1 m/s), nozzle spacing (114.3, 76.2 and 38.1 mm) and water flow rate (15 1/min and 30 1/min). These experimental results provide important information for the development of improved runout table cooling models. The results indicated that, during multiple jet cooling, high heat extraction takes place directly below the nozzles and adjacent to them due to direct impact of water. Lower heat extraction occurs at the locations between the nozzles, i.e. the interaction region. Visual observations of the tests-indicate that, when the water jets hit the strip, a small darkened zone can be observed at the impingement point below each nozzle. In the interaction region, the water flowing from the two adjacent jets interacts with each other and large splashing of the water is observed in this region. The dark zones below all three nozzles expand with cooling of the strip, indicating that the water front is progressing outwards from the stagnation line and more water solid contact is taking place. The boiling curves below each nozzle are similar to each other and clearly show the different boiling regimes while the boiling curve for the interaction region does not show these regimes as clearly. In the interaction region, heat transfer remains relatively low until the water completely wets the strip. The investigation of the effect of strip speed indicated that the heat fluxes are higher for lower strip speeds as the strip spends a longer time under the nozzle. This effect was seen both below the nozzle and in the interaction region. In general, increase in water flow rate increases heat fluxes at all measuring locations due to higher amount of water impinged on the strip surface. The nozzle configuration having two adjacent nozzles at 38.1 mm apart has more cooling capacity than the other two configurations indicating that, having two nozzles close to each other enhances heat transfer.Applied Science, Faculty ofMaterials Engineering, Department ofGraduat
