ABSTRACT In this paper, a buck half-bridge DC-DC converter is used as a single-stage power factor correction (PFC) converter [9,10]for feeding a voltage source inverter (VSI) based permanent magnet brushless DC motor (PMBLDCM) drive. The front end of this PFC converter is a diode bridge rectifier (DBR) fed from single-phase AC mains. The PMBLDCM is […]

Portable Thermoelectric Waste Heat Recovery System
ABSTRACT In view of the fast depleting resources for power generation, search for alternate renewable energy resources and their reutilization has gained importance. Thermoelectric power generation, a concept based on Seebeck effect is the basic principle of this paper. The paper aims to conduct research in the domain of thermoelectric generation and come up with […]
Photodegradation Effect on LLDPE/LDPE/PLA Blend Films
ABSTRACT The present study shows effect of nano calcium carbonate (nano-CaCO3) in LLDPE/LDPE/PLA blend compatibilized with MA-g-PE in photodegrdation. LLDPE/LDPE/PLA blend with and without n-CaCO3 were tested for durability towards weather condition. Prepared blends were exposed for 144 hours (hrs) in accelerated weatherometer. These analyses were completed in outdoor environmental condition like heat, moisture and […]
Secure Blind Storage with Multiple User Access Provision
ABSTRACT In cloud computing, the client has to secure their private data from the server. To solve the concern, a storage scheme is used called as a Blind Server. Blind Server will act as a secured cloud storage service such that it does not know how the files are organized neither the size of each […]
Plastic Injection Molding Process and Its Aspects for Quality: A Review
ABSTRACT Due to environment of competition, industries are into heavy pressure to produce products at a rapid rate. This led to evolve new technologies and production processes. Plastic injection molding process is one of the production technique used to produce plastic products at a rapid rate with minimum defects, but it is a complex process […]
Efficiency Improvement of a Typical Solar Panel with the Use of Reflectors
ABSTRACT A cost effective alternative technique to increase the efficiency of photovoltaics is introduced. The design is fabricated and validated through field testing. The output of a smaller scale solar panel is measured with different reflector materials. Further the reflectors are strategically placed in a way that it would help cool down the solar cells […]
Correlation of Breakdown Strength Parameters of Solid Insulation using Artificial Neural Network (ANN)
ABSTRACT The objective of this work is to determine if a relationship could be found between dielectric strength and other basic properties of electrical insulating materials such as volume resistivity, dielectric constant or relative permittivity and dissipation factor or loss tangent, on empirical basis, by using variables predicted by basic theory. A simple equation to […]
Asymptotic Estimates for Real Zeros of Random Polynomials
ABSTRACT This paper provides asymptotic estimates strong result for real zeros of random algebraic polynomial for the expected number of real zeros of a random algebraic polynomial of the form. The strong result for the lower bound was obtained in the general case by their lower bound was Which is obtained by taking in our […]
Analysis on Camera Attacks and their Defenses on Android Smartphones
ABSTRACT All smart phones have features like camera and touch screen, these features may lead to different types of attacks on smart phones. Modern smart phone platforms let users customize their device via third-party applications found on “app stores” or traditional websites. Application originality is a problem so users are constantly at risk of installing […]
An Empirical Analysis of the Effective Factors of the Production Efficiency in the Garments Sector of Bangladesh
ABSTRACT This paper represents the investigation of the causes of different problems of production through a surveying in different garments manufacturing industries in Bangladesh. Though Bangladesh is a second largest garments manufacturing country, it often fail to meet the production goals in due time. How these factors affect in a production line in a garments […]
