<p>Requirements reuse is based upon the idea that it is possible to reuse requirements from previous software development projects. Requirements reuse leads to efficiency and quality gains in the beginning of the development process. One of the obstacles for requirements reuse is that there is a lack of appropriate tools for it. This work approaches this hinder by identifying properties that are important, that is, that the properties represent something that has so much influence that it should be in a requirements reuse tool. These identified properties may then guide the development when building requirements reuse tools.</p><p>In order to find the properties this work is conducted as a literature study where both tool-specific and non-tool specific articles were searched in order to elicitate the properties. The work focuses on properties present in both tool-specific and non-tool specific articles. This makes the result more reliable since two different sources have identified them. 18 verified properties were identified through this work.</p>

How can we bridge the gap between the lack of construction land and the sustained rapid urban population growth in China? This is a social problem China need to solve in the near future. ‘Land [Fill] The Gap’ is an investigation of the possibility of utilizing existing landfills in Beijing for urban construction in order to accommodate inhabitants, remove landfills and generate electricity from trash. / text

This thesis is an exploration of spatial possibilities within a concrete terminal grain elevator in Thunder Bay, Ontario, Canada. Informed by research into the history, function, and construction of grain elevators, this investigation develops an approach to adaptation that would inhabit the interior spaces while preserving the sense of wonder and intrigue inherent in these structures. Using a program defined only as the most basic requirements for habitation, spatial possibilities are investigated to augment the aesthetic, monumental, and mysterious qualities of the structure, without domesticating it.

Wavelength reuse techniques for bidirectional ultra-wide band (UWB) over fiber (UWBoF) networks are presented. The downstream optical signal from the central station (CS) is reused for upstream data transmission with the original data erased at the base station (BS). Two wavelength reuse schemes for the generation of a clear optical carrier at the BS are theoretically analyzed and experimentally demonstrated. In the first scheme, the wavelength reuse is based on phase-modulation to intensity-modulation (PM-IM) conversion and destructive interferencing using a polarization modulator (PolM) and a fiber Bragg grating (FBG). A theoretical analysis is performed which is verified by an experiment. In the second scheme, the wavelength reuse is based on injection locking of a Fabry–Pérot laser diode (FP-LD) and polarization multiplexing. The UWB injection signal contributes to better BERs of both downstream and upstream services and a lower power penalty cause by the wavelength reuse of the whole system than the baseband signal. A bidirectional point-to-point transmission of over a 25-km single-mode fiber (SMF) using a single wavelength from the CS in each scheme is demonstrated.

Software engineering has been facing a crisis for several years now - there is more demand for new software than there is ability to supply. Software reuse is a potential way to tackle the problems caused by the software crisis with its promises of increased productivity and cheaper development costs. Several software reuse successes have been reported, but these have been predominantly in large, well structured companies. However, there are numerous smaller companies that could also benefit from reuse if it were made available to them. This thesis addresses these issues by implementing a reuse programme in a small company. An incremental approach to reuse introduction is adopted, following the Seven Steps to Success, and 'lightweight' processes are recommended to support the reuse programme. A prototype tool set, ReThree- C++, was developed to automate support for the reuse programme. The results of the case study are presented. The reuse programme was successful, with benefits to the company including both increased speed of production and financial gains from selling reusable components. The challenges faced are also identified. Details of the tool set giving automated support for reuse are also presented. The tool set is an approach to reuse repository control which also integrates information abstraction from C++ source code to generate class hierarchy charts and software documentation automatically. It helps developers store, retrieve, understand and use reusable components. The usefulness of the tool set is shown with an experiment and as part of the case study. The purpose of the thesis is to show that small companies can implement reuse, and that the method presented supports the introduction of a reuse programme. It concludes that although challenges were faced, great benefits can be gained by using the method with automated support for reuse in a small company.
