ABSTRACT: Cascaded Integrator Comb (CIC) filters can perform filtering without multiplying operations and this quality makes practicing engineersand researchers find it highly useful especially for high sample rate signals. Regrettably, the monotonic passband characteristic of the filter generates an unavoidable high passband droop and low attenuation in the stopband which are not acceptable in many applications.Several works have been proposed to improve the performance of CIC filters either in the pass band or stop bandor both in a manner that will provide either smaller pass band error or greater stop band attenuation. This paper presents a new sharpening technique which........

ABSTRACT: Diabetic retinopathy is a microvascular complication of diabetes mellitus, which has a high social cost and requires the intervention of the Medical Bioengineer. This is the reason why the epistemological analysis of emerging trends in the study of diabetic retinopathy is carried out to characterize problematic fields and epistemic matrices that make it possible to integrate an understanding horizon from the field of Medical Bioengineering. The study included three stages: construction of the thematic field; characterization of the elements of the methodology of scientific research programs (hard core, protective belt and heuristics); and reconstruction of the problematic..............

ABSTRACT: Secure and reliable system has become an important exaction in the modern day offices. With the evolution of office equipment's from handwritten notes to desktops to digital storage of confidential information regarding business, client and employee information has to be stored in a secure manner. Cryptography, process of making the information classified, switch it to a form that may be non-readable, keeping it safe from unauthorized people uses modular operations in many of its algorithms. Unlike other arithmetic operations the length of the output does not vary in modular operations. The...........

ABSTRACT: The Arithmetic Logic Unit (ALU) being a central unit for mathematical and computational tasks, its design is critical, in terms of Low Power and High Performance. The major portion of the total power consumption is Leakage power, as process technologies progress from one generation to next generations. There are several methods to reduce leakage power, both in Active and Standby mode. One such technique is Input Vector Control (IVC), which is independent of Process technology and based on Transistor stacking effect, reduces the leakage power in Standby mode. Gravitational Search Algorithm (GSA) is a search algorithm which locates the Minimum Leakage...........

ABSTRACT: Identification of parking space is a major time consuming process at places where the areas are fully crowded. Traffic management depends on parking space detection which will help out to clear the traffic congestion. Parking space detection system using image processing is developed and implemented. Various image processing techniques used for object recognition will be presented and its significance in vehicle detection is clarified. Smart parking lots can be designed with the proposed system along with street and highway lighting a chip or module hardware solution.
