Computer Aided Design (PSCAD) is used to model a Centralized PV Source, Battery Bank, and Distribution Network for 25 DC Houses. Design and modeling of each component in the proposed system are described. For the performance evaluation, emphasis is on voltage stability and system reliability under different operating conditions. Results from the simulation demonstrate the feasibility of the pro...
A Performance Evaluation of Four Bar Mechanism Considering Flexibility of Links and Joints Stiffness
This paper deals with the study of joint clearance on kinematics of mechanism and bearing stiffness along with links flexibility on modal analysis at higher frequency. Literature survey reveals that the studies were carried out for highspeed mechanism considering linkage flexibility without considering bearing stiffness. The method of calculating clearance at joints, checking for orientation of...
Different from the separation between ownership and corporate right of control in traditional companies, human capital and the invisible assets under its control contributes more to the corporate value in high-tech companies than the visible ones. There are many differences between the corporate governance in high-tech companies and the standardized ones, some of which are even essential differ...
Due to the transcritical nature, some of the test methods used in the conventional subcritical refrigeration cycle, such as the liquid refrigerant flow metering method and the water-cooled condenser metering method, are no longer appropriate for evaluating the transcritical carbon dioxide (CO2) compressor performances. This paper introduces a performance test facility taken into account both th...
abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...
The main solution to the problems of persistency and uniqueness in identification of digital objects in a web environment is provided by using digital identifiers instead of URL. The main basis of this solution is resolution mechanism that is used in digital identifier systems. Resolution is the use of indirect names instead of URLs; what worked for the DNS (Domain Name System) in stabilizing i...
Performance assessment of organizations in making strategic decisions for the future is essential. Thus, the efficiency determinations of organizations through planned economic growth in the future system loads are necessary. One of the most important indicators of performance evaluation is measuring efficiency. Banks are one of the most important economic units that provide proper conditions f...
for the performance improvement and higher flexibility in irrigation networks, applications of automatic systems are expanding and on evaluation of their success for achieving the objectives are essential and necessary. considering various equipment, algorithms, and their applications at different levels of irrigation networks, the performance of automatic systems is a function of the performan...
the performance of a supply chain can be evaluated in either a cross-sectional or a time series manner, and data envelopment analysis is a useful method for both types of evaluation. in this paper we develop an index and indicator of productivity change that can be used with radial and non-radial models for supply chain malmquist index. the supply chain malmquist productivity index (scmpi) can ...
