This study investigates the efficiency of manufacturing subsectors in the Zimbabwean economy. The study applied the panel data econometrics approach in the leading manufacturing subsectors from 1980-2005. The quantitative estimates using SFA shows that there are varying efficiencies across sub-sectors and through time. The log-likelihood test shows that there existed technical inefficiency in the production processes in the manufacturing sector. This shows that the industries could have improve their productive capacities with the same amount of inputs. The study shows that average technical efficiencies were falling since 1980 in the investigated sub-sectors. The highest efficiency scores were recorded in the canning and preservation of vegetables and fruits sub-sector which have an average of 98.1 percent efficiency level. The least efficient sectors are the textiles and footwear sectors which had averages of 32 percent and 33 percent efficient levels.

Good product designs merge materials, technology and hardware into a unified user experience, one where the technology recedes into the background and people benefit from the capabilities and experiences available. By focusing on functional gain, critical awareness and emotive connection, even the most multifaceted and complex technology can be made to feel straightforward and become an integral part of daily life. Researchers, designers and developers must understand how to progress or appropriate the right technical and human knowledge to inform their innovations. The 1st International Smart Design conference provides a timely forum and brings together researchers and practitioners to discuss issues, identify challenges and future directions, and share their R&D findings and experiences in the areas of design, materials and technology.This proceedings of the 1 st Smart Design conference held at Nottingham Trent University in November 2011 includes summaries of the talks given on topics ranging from intelligent textiles design to pharmaceutical packaging to the impact of social and emotional factors on design choices with the aim of informing and inspiring future application and development of smart design.

Textile Reinforcement of Elastomers

The technical importance of flexible composite structures needs no emphasis nor has there been any lack of material descriptive of their manufacture or properties. The starting points of such descriptions have invariably been from the viewpoint of the rubber industry and the presence of a suitable textile has been taken for granted, its strength properties indicated and the technological content confined to the manufacturing process within the rubber industry. An attempt is made here to work from the textile outwards. Industrial fabrics are far heavier than garment textiles, are not produced in the same bulk quantities and need to be specially constructed to provide the balance of properties which will combine with those of the rubber to give the final. product. The most important composite structure formed from textiles and rubber is, of course, the pneumatic tyre. It may therefore seem strange that no chapter deals with this. The reason is quite simple. To deal with the structure and design of the pneumatic tyre in a similar depth of detail as is done here for conveyor or power transmission belting, or hose, would require disproportionate space, in fact, a second volume equal in size to the present one. This book discusses from the textile viewpoint the various reinforced rubber structures used industrially with the exception of the tyre. These other uses of industrial fabrics can be discussed in adequate detail and cover the whole range of the technology involved in the space available in the one volume.

The industrial sector is very promising for the use of solar thermal technology, since it accounts for a large share of the total final energy consumption (e.g. 27 % in Germany in 2010) and it predominantly uses the consumed energy as thermal energy (74 % in Germany in 2010). In order to develop this area of application, it is necessary to understand which industrial sectors have the highest potential, which processes within these sectors are most suitable for the integration of solar heat as well as to quantify the possible contribution to the industrial heat demand. For this thesis, the industrial heat consumption in Germany is analyzed, which leads to the selection of the 11 most promising sectors within industry. These are Chemicals, Food and beverages, Motor vehicles, Paper, Fabricated metal, Machinery and equipment, Rubber and plastic, Electrical equipment, Textiles, Printing and Wood. The theoretical potential of solar heat for industrial processes below 300 °C in Germany adds up to 134 TWh per year, the technical potential (considering efficiency measures, limited roof area and a solar fraction) being 16 TWh per year or 3.4 % of the overall industrial heat demand.Solar thermal systems can achieve higher system yields in industrial applications compared to domestic ones. At the same time, systems can be more complex in industrial applications. In order to design and operate solar process heat systems efficiently and to exploit the large potential, possible faults of such systems and their impact have to be evaluated. In this thesis, an implemented solar process heat system is methodically analyzed based on measurements and simulations with a validated model. Several faults are identified and their influence, as well as the influence of a reduced load on the system yield is evaluated. The analysis shows that a reduced load is most influential. Further, the most important impact factors on the system performance are identified: the collector parameters (?0, a1) and load characteristics (mass flow, temperature). The design of solar process heat systems is in many cases very demanding, hence costly. This high effort is a major barrier for a further development of solar heat for industrial applications. The decision to install solar thermal systems is in most cases based on solar heat generation cost. Collector field and heat store size are the most important figures for the estimation of the overall cost of a solar thermal system. Therefore, a simple approach for dimensioning the collector field and heat store is developed in this thesis in order to enable manufacturers and planners on one hand and costumers on the other hand to make a decision in favor or against a solar process heat system. In addition to investment cost, the specific system yield, which is determined for selected process heat applications in this thesis, is necessary to calculate solar heat generation cost. Finally, indications on the necessary accuracy of the load profile are provided to help to reduce effort in the design phase.
