Background: The evolution of distributed web-based applications and cloud computing has brought about the demand to store a large amount of big data in distributed databases. Such efficient systems offer excessive availability and scalability to users. The new type of database resolves many new challenges especially in large-scale and high concurrency applications which are not present in the relational database. NoSQ Read More

Background: Wireless Sensor Network (WSN) is a collection of tiny electromechanical nodes termed as sensors. Sensors are equipped with sensing unit, which is designed for application specific. When deployed either by planned or unplanned after deployment, sensor's energy starts depleting due to various roles like sensing, communication and aggregation. Method: WSN is challenged with limited battery power. The aim is to Read More

Background: With the tremendous increase in the use of social networking sites for sharing the emotions, views, preferences etc. a huge volume of data and text is available on the internet, there comes the need for understanding the text and analysing the data to determine the exact intent behind the same for a greater good. This process of understanding the text and data involves loads of analytical methods, several phas Read More

Background: Transmission of heavy and real-time data over wireless links with Quality of Service in Mobile ad-hoc network is a very challenging task. Bandwidth and battery backup parameters are checks for Quality of Service. To provide the Quality of Service in mobile ad-hoc network, the aliveness of a transmitting node has a great concern. Location-aided routing methods for mobile ad-hoc network have gained popularity Read More

Background: The domain of context-aware recommender approaches has made a substantial advancement over the last decade, but many applications still do not include contextual information while providing recommendations. Contextual information is crucial for various application areas and should not be ignored. Objective: There are generally three algorithms which can be used to include context and those are - p Read More

Background: For the study of gestational diabetes mellitus one of the types of diabetes mellitus a refined model is developed by considering different parameters which plays an important role in the field of gestational diabetes mellitus. Motherhood and a journey of having a child is a blessing of God and a significant occasion for every woman. This disease is associated with the pregnant women and now a day either it Read More

Background: Metal membranes present an alternative approach to conventional membrane materials (polymeric, ceramic), applied mainly for gas separation applications. The major mechanism for the gas permeation though them is called “solution-diffusion” and differs from the respective through the common polymeric membrane materials, hence presenting higher selectivity. Objective: The aim of this article is to provide Read More

Background: Various relevant patents and papers which have reported noncircular gears synthesize the advantages of circular gears and cam mechanisms, and are widely used in many types of mechanical instruments. Hobbing is a better method for fabricating noncircular gears. There are 4 linkagemethods to hob noncircular gears. However, which linkage method should be chosen practically has not yet been reported. Read More

Background: As lithium-ion polymer battery has high energy density and it is easy to be manufactured into different shapes, it arouses more interests of both technology and application recently. The quality of the lithium-ion polymer battery is essential to all the applications, and the detection of bubble defect in cell sheets is critical to the quality control of batteries. Recent patents on flaw detection in cell sheet are re Read More

Background: The oil-water relative permeability curve is an important experimental data and basis for oilfield development scheme and dynamic prediction. The characteristics of oil and water relative permeability curves in different reservoirs are otherness. Objective: In order to enable various effects to be reflected in the standardized relative permeability curve, the standardized relative permeability curve can reflect t Read More
