Improving the Application of the "Learning Curve"
Project Report from the year 2017 in the subject Engineering - General, , language: English, abstract: There exist some fields in which the learning curves can be applied; they have a much wider applications including manufacturing and marketing strategy. However, they underlay the concept of continuous improvement, pricing decisions, work scheduling, standard setting, direct labour budget etc. Learning curve states that decreasing man hours are required to accomplish any repetitive task as the operation is continued; then knowledge of learning curve can be useful both in planning and control. Estimates of learning curves are used in many applications in organizations and they can be effecti...
Subsidy Reform in the Middle East and North Africa
In the Middle East and North Africa (MENA) countries price subsidies are common, especially on food and fuels. However, these are neither well targeted nor cost effective as a social protection tool, often benefiting mainly the better off instead of the poor and vulnerable. This paper explores the challenges of replacing generalized price subsidies with more equitable social safety net instruments, including the short-term inflationary effects, and describes the features of successful subsidy reforms.
System Engineering and Energy Programs
Document from the year 2017 in the subject Engineering - Power Engineering, University of the Witwatersrand, language: English, abstract: First off, this project gives insight into how to define various systems management (project management and systems engineering) terms and to answer to the frequently asked questions in systems management. Specifically, to think like a systems engineer by changing the way of approaching and specifying a solution or addressing problems. Then the overall purpose is to use and apply Systems Engineering approaches to solve the high levels of unstructured problem situation and try to structure a debate concerning actions for improving the problem "energy program" situation within the System (University of Witwatersrand-Johannesburg).
Implementing Operations Strategy Through Lean Processes within the South African Healthcare System
Document from the year 2018 in the subject Health - Public Health, University of the Witwatersrand, language: English, abstract: The purpose of this paper is to investigate how operations strategy and lean concepts can be applied within the south Africa’s healthcare organisations and the degree to which both Lean and operations strategy are understood by senior-level National Health Service (NHS) personnel, based on the process of ongoing longitudinal cases studies. Further interviews and data analysis will examine actual performance of Lean capabilities within the NHS.
CNC Milling Programming. Linear & Circular interpolations for a workpiece
Research Paper (postgraduate) from the year 2017 in the subject Engineering - Mechanical Engineering, University of the Witwatersrand, language: English, abstract: A combined 3D linear and circular interpolation principle is developed on the basis of the 3D linear and circular interpolation principles. The task was to choose and design a creative item to be machined using CNC machining, which then required to write a code using CNC language. Prior to the machining process, we did a Computer Aided Design (CAD) drawing of the workpiece. The drawing was further modified with the final model drawn using Auto Desk Inventor. We used foam for our model and a 31 diameter end mill tool. The main problem that was experienced was the cutting time; the model took longer to be complete. The cutting time was affected by the complexity of the design, chosen tool size and the cutting technique. Besides, we learnt from the demonstration that the shorter the constructed code the more robust it is, using a bigger tool is more efficient in terms of saving energy and time, and that if the code is correct the CNC machine model becomes identical to that of the product Design.

Analysis and Optimization of a biodiesel production from WCO
Project Report from the year 2017 in the subject Engineering - Industrial Engineering and Management, , language: English, abstract: The conventional approach of biodiesel production is transesterification, using oil and alcohol in the presence of a catalyst with glycerol as a by-product of the reaction. Product quality is dependent on the type and amount of catalyst, type of oil feedstock, alcohol-to-oil ratio, etc. In terms of the best process, currently the alkali catalyzed process is the most profitable while the enzymatic based one is even more promising due to the lower consumption of energy and water; however it requires that the enzyme cost is reduced. The reason that biodiesel is no...
365 Samurai and a Few Bowls of Rice
Employs full-page panels to tell the story of an Edo-era swordsman's quest for survival and enlightenment. When Ningen leaves his dojo at the request of his master - to travel the world and grow as a swordsman - he embarks on a journey that becomes a metaphor for the cycle of life and every human's spiritual growth.
Using Cnc for Mercedes Benz LOGO Design
Project Report from the year 2017 in the subject Computer Science - Programming, language: English, abstract: This report covers the work that was carried out by a group of researchers on CNC (Computer Numerical Control) programming and machining. The task was to choose and design a creative item to be machined using CNC machining, which then required to write a code using CNC language. Prior to the machining process, we did a Computer Aided Design (CAD) drawing of the Mercedes Benz logo. The logo was further modified with the final model drawn using Auto Desk Inventor. We used foam for our model and a 10 diameter end mill tool. The main problem that was experienced was the cutting time; the model took longer to be complete. The cutting time was affected by the complexity of the design, chosen tool size and the cutting technique. We learnt from the demonstration that the shorter the constructed code the more robust it is, using a bigger tool is more efficient in terms of saving energy and time, and that if the code is correct the CNC machine model becomes identical to that of the product Design.
Dictionary of African Biography
From the Pharaohs to Fanon, Dictionary of African Biography provides a comprehensive overview of the lives of the men and women who shaped Africa's history. Unprecedented in scale, DAB covers the whole continent from Tunisia to South Africa, from Sierra Leone to Somalia. It also encompasses the full scope of history from Queen Hatsheput of Egypt (1490-1468 BC) and Hannibal, the military commander and strategist of Carthage (243-183 BC), to Kwame Nkrumah of Ghana (1909-1972), Miriam Makeba and Nelson Mandela of South Africa (1918 -).
