About the Cover

In order to accurately determine the growth of greenhouse crops, the system based on Single Chip 8051 microcontroller and wireless sensor networks is developed, it transfers data through the wireless transceiver devices without setting up electric wiring, the system structure is simple. The monitoring and management center can control the temperature and light intensity of the greenhouse, measure the water content, and collect the information about intensity of illumination, and so on. The system has advantages of low power consumption, low cost, good robustness, extended flexible. An effective tool is provided for monitoring using MATLAB and analysis decision-making of the greenhouse environment.

SS Savannah: the first steamship to cross the Atlantic Ocean in May 22, 1819

Brindha V

S.S. Savannah, the elegant ship was the first steam-powered vessel to cross and recross the Atlantic Ocean, returning without an engine bolt or screw out of place. It sailed from the harbor on May 22, 1819 and reached Liverpool 27 days later. The ship's daring commander, Captain Moses Rogers, had chosen Stephen Vail to build the Savannah's engine.

Fuzzy Logic Based Controller Design for Brushless DC Motor Drives

Pranshu S

The paper presents a fuzzy logic controller for brushless direct current (BLDC) motor drives. Initially a fuzzy logic controller is developed using MATLAB Fuzzy-Logic Toolbox and then inserted into the Simulink model. The dynamic characteristics of the brushless DC motor such as speed, torque and current of the inverter components are observed and analyzed using the developed MATLAB model.

Formulation and evaluation of Sumatriptan succinate floating bilayered tablets

Brahmaiah Bonthagarala, Sreekanth Nama, Sasikanth Kothamasu, Mohanprasad Badamuddala, Sudarshan Donthiboina

Objective of the study is to formulate and evaluate Sumatriptan succinate floating bilayered tablets using different viscosity grades of HPMC polymer i.e. HPMC K15M and HPMC K100M in combination with carboxy methyl cellulose sodium and poly ethylene oxide in different ratios in sustained release portion and superdisentegrants in immediate release portion to get a bimodal release formulation and the prepared bi-layer tablets are evaluated for some of the properties like Thickness, Hardness, Friability , Uniformity of weight, Content uniformity, In vitro dissolution, In vitro buoyancy studies for sustained layer.
