Digital Color Image Watermarking using DWT-DCT Coefficients in RGB Planes

Digital image watermarking is used to identify the authenticity and integrity and to show the identity of its owners. This paper presents a more secure method for copy right protection. In the proposed method, the color image is decomposed into 3 color channels Red, Green and Blue and then DWT and DCT are applied to B channel of the R, G and B channels. The colored Watermark image is decomposed into R, G, B channels and DCT is applied to all the channels separately. R, G, B channels of watermark image are embedded into mid frequency coefficients of B channel already selected. The performance of proposed algorithm is measured by using Mean Square Error, Peak Signal to Noise Ratio, Standardized Correlation and Normalized Correlation. A comparative study of proposed scheme with the existing methods which uses DWT-DCT transforms is carried here and results shown

A UNIQUE POWER CONVERTER STRATEGY BASED DISTRIBUTED GENERATION SCHEME FOR DIFFERENT LOAD CONDITIONS

With the use of the renewable sources increasingly, application of the distributed generation (DG) in the distribution system acquired more attention. The DG systems are powered by micro sources such as fuel cells, photovoltaic (PV) systems, and batteries. Energy storage systems (ESSs) are enabling technologies for well-established and new applications such as power peak shaving, electric vehicles, integration of renewable energies, etc.  Distributed Generation (DG) has become increasingly more accepted since the demand for reliable and secure power systems with high power quality increases. This project presents the Distribution Generation system. The power flow is determined by controlling the amplitude and angle of displacement between the voltage produced by the DG and the grid voltage, i.e., the control variable is the same before and after the islanding mode occurs. The voltage control provides the capability to supply different kinds of loads to the DG system, such as linear, nonlinear, and motor, balanced, or unbalanced, even if the DG operates in the islanding mode. These kinds of controls are suitable for DGs operating in parallel as each of the DGs are connected to the grid through a distribution transformer (DT). Conversely, the other approaches introduced in are more effective. The operation of a distributed generation (DG) system driven by a dc-dc step-up converter and a dc-ac voltage source inverter (VSI) interfaced load/grid achievement. The simulation results are presented by using Matlab/simulink software

CASE REPORT ON HALOPERIDOL INDUCED PARKINSONISM AND IT’S MANAGEMENT

Schizophrenia patients who are in the treatment with Typical Anti-Psychotics drugs are at higher risk of developing extra pyramidal symptoms. The objective of this case report is to enhance awareness for medical practioners concerning Typical Anti-Psychotic drugs induced Parkinsonism/Extra Pyramidal Syndrome (EPS). We report a patient, who is a known case of Chronic Schizophrenia, was treated with Haloperidol 5mg t.i.d for one month, this caused the patient to suffer with Extra Pyramidal Syndrome, and then the patient was advised to stop Haloperidol. Instead Atypical Anti-Psychotic Olanzapine 2.5mg orally was prescribed which showed gradual improvement and recovered from Extra Pyramidal syndrome after a month.&nbsp
