Qos-Based Web Service Discovery And Selection Using Machine Learning

In service computing, the same target functions can be achieved by multiple Web services from different providers. Due to the functional similarities, the client needs to consider the non-functional criteria. However, Quality of Service provided by the developer suffers from scarcity and lack of reliability. In addition, the reputation of the service providers is an important factor, especially those with little experience, to select a service. Most of the previous studies were focused on the user's feedbacks for justifying the selection. Unfortunately, not all the users provide the feedback unless they had extremely good or bad experience with the service. In this vision paper, we propose a novel architecture for the web service discovery and selection. The core component is a machine learning based methodology to predict the QoS properties using source code metrics. The credibility value and previous usage count are used to determine the reputation of the service.Comment: 8 Pages, 3 Figure

Web service QoS prediction using improved software source code metrics

Due to the popularity of Web-based applications, various developers have provided an abundance of Web services with similar functionality. Such similarity makes it challenging for users to discover, select, and recommend appropriate Web services for the service-oriented systems. Quality of Service (QoS) has become a vital criterion for service discovery, selection, and recommendation. Unfortunately, service registries cannot ensure the validity of the available quality values of the Web services provided online. Consequently, predicting the Web services' QoS values has become a vital way to find the most appropriate services. In this paper, we propose a novel methodology for predicting Web service QoS using source code metrics. The core component is aggregating software metrics using inequality distribution from micro level of individual class to the macro level of the entire Web service. We used correlation between QoS and software metrics to train the learning machine. We validate and evaluate our approach using three sets of software quality metrics. Our results show that the proposed methodology can help improve the efficiency for the prediction of QoS properties using its source code metrics

A clinical study on Kalladaippu (Urolithiasis) with the evaluation of siddha drug Karpoora Silasathu Parpam

The clinical study on Kalladaippu was carried out in Post graduate department of Pothu Maruthuvam, Government Siddha Medical College, Aringar Anna Hospital, Chennai – 106 during the period of 2015-2017. A total of 40 patients were treated in the Outpatient department. The clinical and pathological assessment was carried out on the basis of Siddha and Modern aspects. All the patients were treated with Karpoora silasathu parpam with Ilaneer 130 mg b.d daily, after food for duration of 48days. males were mostly affected (57.5%). Most of the patients were in the age group between 31-40 years (52.5%). Most of the patients were from Neithal Thinai (82.5%). In this study, most of the cases (35%) were house wives. Most of the patients were affected in Muthuvenirkaalam (37.5%). In Vali, Abanan (100%), Viyanan (100%), Uthanan (30%), and Devadhathan (27.5%) was affected. In Azhal, Saathagam (100%), Ranjagam (22.5%) was affected. In Iyyam, Santhigam (30%) was affected. In Ezhu udal kattugal, Saaram (100%), Seneer (22.5%) and Enbu (30%) was affected. Regarding naadi, (60%) had Vatha Azhal was the most common naadi observed. The Toxicological studies of the trial medicine reveal no toxicity. The Pharmacological studies reveal that, the trial drug has Anti Urolithiatic activity. Bio- statistical analysis of the clinical trial reveals significant p value < 0.05 and ˂ 0.01 and concluded that the treatment is effective and significant. Regarding grading of the result, 17 cases (42.5%) shows good improvement, 19 cases (47.5%) shows moderate improvement, 4 cases (10%) shows poor improvement. CONCLUSION: Kalladaippu is a common disorder of pitha kutram. The dearranged pitham is settled down by the ingredients of trial medicine having astringent taste thereby the medicine acts as ethirurai maruthuvam to cure the disease. Most of the cases noted in muthuvenir kalam and elavenir kalam in my clinical trial. So, people should take all preventive measures during this period and take enough water. Toxicological study shows no acute and sub - acute toxicity. Pharmacological study reveals that the trial medicines possess Anti Urolithiatic activity. During clinical trial, no adverse reactions or complications were observed. The trial medicine Karpoora silasathu parpam showed good results with relieving symptoms in almost 90% patients. Once again Siddha medicine proves itself as a great boon to mankind

Solar Based Hydroponics Cultivation

The main aim of the project is to grow a plant without a soil by using solar supply. It uses the 90% of water efficiently. As compared to soil cultivation, the production increases by 3 to 10 times. Hydroponics is the method of growing plants without soil by using mineral nutrients solution in water solvents usually an inorganic substrate with rock wool to be the most common worldwide. Agriculture in the growing countries faces some serious challenges in the coming decades that include: competition for water, energy resources, rising costs,increased world population, competition for international markets, changes in climate,environmental impact and uncertainties in the effectiveness of the current European policies as regards adaptation strategies. Controlled environments become an important tool in agriculture production and study chains. Hydroponics is a promising technology and becomes very popular in the area of agriculture, specifically in urban farming. Hydroponic systems have found a rapid development and widespread use in recent years. In hydroponicscultivation, the recording of several parameters helps cultivators to develop optimal conditions for the growth of plants. In this paper, we present a low-cost, high-reliability prototype for real-time measurements in hydroponics cultivation

Multiphysics Analysis of a Magnetorheological Damper

&nbsp; &nbsp; &nbsp;A Magnetorheological damping has evolved as a potential tool in vibration control. The design of magnetorheological damping involves analysis of fluid flow principles and electromagnetic flux analysis. This research paper involves design and analysis of a magnetorheological damper employed for vibration control. The analysis is carried over by considering the domain as an axisymmetric model. The damping force of the damper depends upon the shear stress due to fluid viscosity and yield stress induced due to magnetic flux applied. The damping force generated by the damper is calculated

Luminescence Studies on Pr3+& Yb3+ Doped Cadmium Calcium Pyrophosphate Nanophosphors

The Cadmium Calcium Pyrophosphate doped with Pr3+ and Yb3+ was prepared by solution combustion synthesis. The luminescence studies and chromatic properties of the prepared sample were examined in the present study. The luminescence spectra of CdCaP: Pr3+ shows relevant peaks with emission at 599nm upon excitation of 445nm, whereas CdCaP: Yb3+ shows a peak at 536nm when excited with 254nm. The CIE 1931 chromaticity color coordinates for CdCaP: Pr3+ & CdCaP: Yb3+ were located in orange and greenish-yellow regions respectively. CCT and color purity values of the prepared samples were evaluated using McCam empirical formula and respective equation of color purity. Color Rendering Index (CRI) values of the prepared samples were calculated using the color calculator. © 2020 Author(s).Authors are thankful to UGC-DRS & DST-FIST, New Delhi for financial assistance to the department of physics, Acharya Nagarjuna University.
