Agricultural activities act as dominant polluter of groundwater due to increased fertilizers and pesticides usage. Bist-Doab region, Punjab, India, is one such region facing deterioration of groundwater quality due to usage of fertilizers. This study aims in delineating and evaluating the groundwater quality in the region. Water samples are collected from canals, reservoir, and shallow and deep groundwater...
This paper presents an active realization of an eighth order current mode Butterworth filter function using Multioutput Operational Floating conveyors (MOOFCs) and grounded passive components. The proposed realization is based on cascading a new low component single input multi output (SIMO) current mode universal biquadratic filter (UBF). The UBF is constructed employing only two MOOFCs, four grounded...
This paper presents a new realization of current mode first order all pass filter employing only one Operational Floating Conveyor (OFC) along with two grounded admittances. The proposed circuit is simple and has high output impedance enables easy cascading in current mode operations. PSPICE simulations using 0.5 m CMOS parameters at supply voltage of 0.75 volts confirm the validity and practical...
This paper introduces a single input multi output (SIMO) current mode universal biquadratic filter using low voltage Multioutput Operational Floating Conveyors (MOOFCs) along with grounded passive components. The circuit is constructed with two MOOFCs, and four grounded components. The circuit can realize all standard biquadratic responses i.e., low pass, high pass, band pass, band elimination and...
Summary form only given. Regression testing is often performed as part of the software maintenance process. The amount of tests cases for a large-scale system can range from several hundred to many thousands, requiring significant computing resources and lengthy execution times, often precluding their use in an interactive setting. Traditional approaches to reduce the execution time for regression...
JUnit is the de-facto framework for creating and executing unit tests. This paper introduces a distributed execution framework for JUnit test cases called HadoopUnit, which is built upon Hadoop: an open-source platform for running applications that process vast amounts of data on large clusters built of commodity hardware. The primary motivation behind developing HadoopUnit was to test Hadoop production...
This paper presents a new versatile active circuit for the realization of impedance converter, ideal grounded inductance, FDNR, and R/C multipliers through appropriate selection of passive elements. The proposed circuit is realized using low voltage CMOS Operational Floating Conveyors (OFC) and grounded passive components, without using any matching constraints. This makes it attractive for IC implementation...
The paper presents a new Multi Inputs and Single Output (MISO) VM Universal Biquadratic Filter (UBF) employing only two low voltage dual output current conveyors (DOCCIIs) along with two resistors and two capacitors. The proposed circuit realizes six standard biquadratic responses, viz., low pass high pass, non inverting band pass, inverting band pass, band elimination and all pass. The filter enjoys...
A 4 DOF IR/EO Gimbal system is used for surveillance and navigation of UAV's. The purpose of this paper is to present a dynamical model for the gimbal, emphasizing on the significance of camera offset in case of short distances between end effector and the moving target. Two facets of this article are kinematics and the derivation of equation of motion. The proposed dynamical model can defy not only...
A 6DOF Moving Base manipulator is a parallel manipulator with six variable-length actuators but unlike Stewart Platform both ends of actuators are mounted on moving plates. It dynamical structure is designed to reject the disturbances, which base plate suffers, and keep the top plate leveled with respect to the inertial frame. However the closed kinematics chain and parallel structure linkage structure...
Service-oriented architecture (SOA) is a paradigm that organizes and uses distributed capabilities to bring together a technical solution to a business problem. The central concept of SOA revolves around modularized implementations of business logic known as services. SOA is different from traditional systems in that functional requirements are mapped to business process models and are implemented...
The main contribution of this paper is decomposition/separation of the composite induction motors load from measurement at a system bus. In power system transmission buses load is represented by static and dynamic loads. The induction motor is considered as the main dynamic loads and in the practice for major transmission buses there will be many and various induction motors contributing. Particularly...
Testing is one of the five main technical activity areas of software engineering. Most students are introduced to testing as part of an overview course on software engineering fundamentals. A few students are fortunate to learn more about the topic in specialized courses that focus on aspects of traditional software testing, such as black-box and white-box testing. This paper argues that there is...
