Development of virtual laboratory as an educationalresearch tool in food processingChi, Minli, 1965- January 2005 (has links)
Personal computers (PC) and high level programming techniques have been developing so rapidly during last decade leading to new and exciting opportunities in the field of education. The purpose of this research was to develop food processing virtual labs as efficient teaching and study tools for food processing courses using user-friendly computer languages (VC++, MFC and OpenGL). A 3D graphic technique was employed in this study as a specific objective to generate 3D graphics in the visualization mode. / According to functionalities, virtual labs were designed for three basic simulations: (1) Calculation simulations, which perform various calculations related to food processing. These simulations help users to remember and understand the formula used in process calculations. Several simple concept calculations were included: conduction heat transfer in steady state through individual and composite slabs; two-component mass balance systems, Pearson rule applications; freezing and thawing time calculations; (2) Animation simulations, which are aimed to visualize processing scenarios for different physical phenomena or working principles. Included in these simulations were: conduction heat transfer through single and multiple walls under steady state; mixing processes involving two and three component systems and Pearson rule concept; freezing and thawing processes through slab, cylinder, and sphere, the three regular shapes, agitation thermal processing modes which include axial agitation and end-over-end agitation in rotational retort; (3) Virtual equipment simulations, which are aimed to dynamically simulate a real operating environment and to demonstrate equipment working principle, internal structure, and operating procedures. The simulated equipment include a horizontal retort used in thermal processing and a high pressure processing equipment used in non-thermal processing. / The food processing virtual labs provide a new way in teaching and learning, with no risk, time or place limitations, and are cost effective. The simulated scenarios and equipment can be used as teaching tools in food processing courses, which provide an efficient way to the instructor/assistant. Instructor/assistant can dynamically and repeatedly demonstrate the operating process for the simulated equipment in a vivid and interested manner. Also students can get intuitive understanding by viewing these simulations. Computers are the waves of the future; however, traditional learning techniques should not be forgotten.* / *This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation). The CD requires the following system requirements: Windows 95 or higher.

The design of a National Food Technology and Research Centre in Marabastad, Tshwane : with the aim of supporting the introduction of a local, urban food production system.Loock, Frandah. January 2012 (has links)
Thesis (MTech. degree in Architecture (Applied Design))--Tshwane University of Technology, 2012. / The aim of this dissertation is to design a National Food Technology and Research centre in Marabastad, Tshwane. The focus of the proposed project is to introduce an urban food system by way of reviewing available foodstuffs, seeds and products in a scientifically responsible manner. This will be achieved by attempting to create an awareness concerning food and all related aspects, to challenge the old habits of consumers and to promote a responsible and sustainable lifestyle. The centre's programme will aim to manage innovative research and develop public and community activities related to future urban agriculture and related food technology. This proposal will also aspire to initiate networking and development of relationships amongst farmers (producers), the commercial sector (production and processing sector) and the consumer (public). The architectural intervention will promote social and economic development, contributing to the general self-sufficiency and up-liftment of the Marabastad community. The architectural language is in contrast to the surrounding context but simultaneously celebrates the existing Marabastad social culture and architectural elements. This development intends to rejuvenate the existing proximate environment and establish an urban building typology, which aims to contribute to the future development initiative for Marabastad. The design and layout of the facilities are based on social, pragmatic and cultural actions, evident within Marabastad and particularly the area known as Jazz Square, between Bloed and Struben Streets. The proposed Research Centre will consequently embrace and respond to the site's unique and historical genius loci.
