Abstract

The objective of the economic dispatch problem is to schedule the committed generating units output so as to meet the required load demand while satisfying the system equality and inequality constraints. The improvements in the scheduling of generating units can lead to significant cost savings. This paper presents a sequential approach for solving the economic dispatch of thermal units. This is a maiden attempt has been developed to obtain the optimal dispatch solutions for all achievable load demands of a system in single execution. The feasibility of the proposed method is demonstrated for suitable test systems. The generator operational constraints such as ramp rate limits and prohibited operating zones and transmission loss are considered. The simulation results are compared with the recent reports in terms of solution quality. Numerical results indicate an improvement in the cost saving and hence the superiority of the proposed method is also revealed for economic dispatch problems.

Abstract

Objectives: Vedic mathematics contains 16 formulae or Sutras. Employing these shortcut formulae in the computations of Elgamal cryptographic algorithm will reduce the logic elements, layout area and power consumption. Methods/Statistical Analysis: Simulation programming for the paper has been done through Verilog HDL code in MODELSIM software and performance parameters like speed, power etc., using XILINX software. Findings: In this paper, when employing these Vedic formulae, lesser number of logic elements are consumed when compared with conventional method. Improvements/ Applications: By investigating the various Sutras in Vedic mathematics, it has been observed that speed is increased and layout area is minimized.

Abstract

Objectives: This study proposes for analyzing the usage of novel as a teaching tool to English learners in India. Teaching of English as Second Language (ESL) to speakers of English outside Britain poses peculiar problems. Previous literature works are not written properly for the purpose of class room learning and teaching. This article lists out reasons for teaching English through novels in ESL classes. It is proposed to find out whether the novels can enrich the students' knowledge of English culture and whether they can enhance their language skills. Methods: For the purpose of the present study, a class consisting of 50 students was identified. A pretest was conducted to assess the level of understanding of linguistic skills, vocabulary and the knowledge of grammatical structures of the students. After the completion of the project, a test was conducted to find out the improvements in the learners. Findings: The data of the pre-test and post-test are analysed. It is evident that the use of novel as a teaching tool has kindled the interest of the learners in knowing about a foreign culture. The experiment has also proved that the innovative use of the novel has improved the language skills of the learners. Applications: This method of teaching English through novel can be used in the English taught countries as a second language. Use of novel as a tool is both innovative and useful to the non-native learners.
