Multipliers form the heart of any DSP operation and determine the performance of general-purpose microprocessors. Wallace tree is an efficient hardware implementation of a circuit that multiplies two integers. It consists of three stages. In the first stage, the partial product matrix is formed or generated. This is to mean multiplying (ANDing) each bit of one of the arguments called multiplier, by each bit of the other arguments called multiplicand. Depending on position of the multiplied bits, the wires carry different weights. Reduce the number of partial products to two by layers of full and half adders. Group the wires in two numbers, and add them with a conventional adder. In the second stage, this partial product matrix is reduced to a height of two through taking any three wires with the same weights and input them into a full adder. In the final stage, these two rows are combined using a carry look ahead adder. Here, if there are two wires of the same weight left, input them into a half adder or if there is just one wire left, connect it to the next layer. The work results in reduction of number of gates that would be used in the design which in turn results in reduction of cost and delay. 2009-01-01T00:00:00Z http://hdl.handle.net/123456789/2355 Title: Customs Valuation System in Ethiopia Authors: Seifu, Tenkir Abstract: The study assessed the customs valuation system applied in Ethiopia and investigated the existing problems in the system. The methods adopted in the study include documentary analysis, in-depth interview and self administered questionnaires. The results suggested that the Customs Valuation System in Ethiopia does not provide fair, neutral and uniform valuation and does not effectively protect traders from risk of arbitrary valuation by the customs officers. There is also risk of revenue loss to the government due to under invoicing of imports by the traders since controlling mechanisms such as Post Clearance Audit (PCA) are not adequately developed. Therefore, the Government of Ethiopia needs to strengthen the controlling mechanisms within the customs valuation system since duties and taxes on foreign trade contribute the significant portion of its tax and duty revenues. 2009-01-01T00:00:00Z http://hdl.handle.net/123456789/2351 Title: Challenges of Quality Management in Private Higher Education Institutions: The Case of St. Mary’s University College Authors: Worku, Seble Abstract: In the last one decade, more than 60 private higher education institutions were inaugurated in Ethiopia. As part of their growth in number, they need to give extra attention to their quality management process because this is their essence of existence and their future development. This paper is designed to asses the major challenges faced by private higher academic institutions in their quality management process focusing on St. Mary’s UC. Both primary and secondary data were collected. Based on the questionnaire collected from the top management, academic, nonacademic staffs and students from the selected UC data analysis and interpretation were made. From the external environment, some selected employers were a part of this study. Finally the research paper concludes and recommend. 2009-01-01T00:00:00Z
