Heat Transfer and Exergy Analysis of Methane-Air Flame Impinging on Plane Surfaces
Abstract: Exergy and heat flow have been numerically investigated for flame impinging on flat circular plates. The maximum work available when the system is brought to thermodynamic equilibrium state with its surrounding is known as the exergy of a system. This state of equilibrium of the system depends on the pressure, temperature, and composition of environment. Efficiency based on exergy is otherwise known as the second-law efficiency which measures the usefulness …

Development and Investigation of Minimum Power Non-contact Swirl Vane Gripper
Abstract: The Swirl vane gripper is a new non-contact gripper, which uses negative pressure created by the air swirling flow to create an upward lifting force. This upward force can be used to lift an object, which is placed underneath the gripper. In comparison with other non-contact grippers, this gripper is electrically actuated (rather than pneumatically) and hence require less power to generate same lifting force as produced by other grippers. …

Self-Compensation of Commutation Phase Error for Brushless DC Motor
Abstract: BLDC motors are synchronous motors powered by DC electricity via an inverter which produces an AC electric current to drive each phase of the motor via a closed loop controller. Electronic commutation is the on-and-off of the semiconductor switches at appropriate time to turn stator windings. Commutation phase ripple is generated due to the different exchange rate between outgoing phase current and incoming phase current of inverter during commutation period. …

Speed Control of An Inverter Fed Three-Phase Induction Motor Using IP Controller Considering Core Loss and Stray Load Loss
Abstract: Consideration of core losses and stray load losses to design a controller of an inverter fed induction motor are affected to the flux and torque decoupling strategy adversely. As a consequence, the detuning of field-oriented control (FOC) is required. The detuning strategies have been developed in some literatures. But the implementation of detuning becomes difficult because of higher order expression. In general, the controlling and estimation of AC drives are …

Automatic Language Identification using Basic Signal Class
Abstract: Automatic language identification (ASLID) is a problem of identifying an unknown language from spoken utterance by a computer. A segmental approach to ASLID based on the assumption that the acoustic structure of languages can be estimated by segmenting speech into three basic classes of speech signals. This paper presents a procedure of ASLID with the details of methodology and the results without recognizing the words, but the lengths segments of …

Native Language Identification from Spoken Indian English
Abstract: Automatic speech recognition (ASR) systems that facilitate voice based search and information retrieval have gained importance recently. While the performance of ASR systems for Indian languages have improved in the recent past. They have yet to gain wide acceptability as much as the ASR systems for English spoken by Indians. Almost all Indians learn English as a second or third language. So, the phoneme set and the prosody of native …

The fundamental premises of efficient linear regression and applying Regression
Abstract: Linear regression is a statistical technique for estimating the value of a dependent variable from an independent variable. Linear regression is a way to assess how two variables are related.A dependent variable is predicted using this modelling technique based on one or more independent factors. Many analyses are based on linear regression. Sometimes the data must be changed to satisfy the needs of the analysis, or extra room must be …

Effect of Compressibility on Undrained Bearing Pressure of Circular Footing Resting on Two-Layered Clay
Abstract: The present study aims to investigate the behavior of a circular foundation on layered clay of varying properties. There are several solutions for the bearing capacity of footings on two-layered clays, but none of them considered the compressibility of the strata. An underestimation of the soil bearing capacity is the main cause of failures. The typical difficulty in estimating the capacity of soil is its complicated behavior attributed to the …

Experimental Investigation of Overall Heat Transfer Coefficientin Drop wise Condensation
Abstract: The experiments are performed to study the heat transfer characteristics over a drop wise condensation. The phenomenon of drop wise condensation is in which the condensate forms into drops rather than covering the entire cooling surface with a continuous film. In drop wise condensation, heat transfer coefficient produced is 2 to 10 times greater than those produced by film wise condensation. Hence drop wise condensation is desirable as it is …
