 Abstract

The feasibility problem is the problem of finding a point in S. The convex optimization problem is the problem of minimizing a convex function over S. We present a new algorithm for the feasibility problem. The notion of a volumetric center of a polytope and a related ellipsoid of maximum volume inscribable in the polytope are central to the algorithm. Our algorithm has a significantly better global convergence rate and time complexity than the ellipsoid algorithm. The algorithm for the feasibility problem easily adapts to the convex optimization problem.

 Abstract

Forced air circulation become more important for heating and cooling of the place of living for more comfortable life. There are several types of Duct namely circular and rectangular used for different purposes. Heating, ventilation and air conditioning (HVAC) system designs require good understanding of variation of velocity, pressure and energy throughout the duct in three dimensions. In this paper theoretical analysis has been performed using Ansys-CFX. The physics of the turbulent air flow in duct has been captured by analyzing variation of velocity, pressure, turbulent kinetic energy and wall shear stress in terms of contour plots and graphical plots.

 Abstract

Various anthropogenic activities, whether destructive, conservative or creative, have affected the environmental processes in different ways. Mining is such an anthropogenic activity which is responsible for the alteration of human ecological environment to a great extent. Its Environmental impacts include disruption of vegetation, soil and groundwater. Mining is not only responsible for influencing the quality of land but also have far reaching impacts on air, water, vegetation and human and wildlife.

 Abstract

Betel vine (Piper betle L.) belongs to genus Piper of the family Piperaceae. Leaves of Piper betle posses several bioactivities and are used in traditional medicinal systems. Many research studies on Piper betle has reported that it contains important chemical constituents and are acts to arouse action for its medicinal properties like anticancer, anti-allergic, anti-malaria, anti-filarial, antibacterial, antifungal study, insecticidal, antioxidant, anti-diabetic, gastro-protective, cytotoxic, wound healing activity, chlorophyllase activity, oral hygiene, and anti-asthmatic effect.

In e-commerce today, contents available for users to explore are overwhelming as an average e-commerce website is about seventy percent (70%) more than a physical store in a total number of users and items. Thus, there arises the need to filter, prioritize and efficiently deliver relevant information. We use recommender systems for this purpose. Recommender systems are at the forefront of the ways in which content-serving websites like Facebook, Amazon, Spotify, etc. interact with their users. Book Recommendation system is such a recommender system built for book lovers. Using your profile, our system uses Machine Learning methods to provide you with highly personalized book recommendations. We are using a hybrid recommender system in order to provide recommendations from the dataset given by Goodbooks users (ratings and item features). We also offer more "conventional" suggestions that focus solely on the book's strengths. Audiobooks can improve readers' literacy by changing the way they listen, read, and learn. Our system allows users to download the audiobook and enjoy their reading time.

 Abstract

Currently, the differential function has been widely used in transformer protection relay. However, the main issue of this technique is assigned to the relay mis operation during the presence of inrush currents and current transformer (CT) saturation. In the literature, these limitations have been overcome with the use of tools based on artificial intelligence and signal processing, such as the methods based on artificial neural networks and wavelet transform. This paper proposes a method based the ANNs and wavelet transform to detect and classify disturbance in the power transformer accurately. The algorithm uses wavelet based disturbance detector in order to detect any disturbance related to a power transformer, whereas a neural network based routine is used to classify the disturbance type (internal fault, external fault and transformer energization) appropriately, as well as to classify the internal faults. Several events were simulated, such as external and internal faults, with variations of fault resistance, fault inception angle, and fault type parameters, as well as transformer energizations. The method presented an excellent success rate regarding the correct classification of the disturbance as well as an accurate fault classification.
