A Streamlined, Cost-Effective Database Approach to Manage Requirements Traceability

Requirements traceability offers many benefits to software projects, and it has been identified as critical for successful development. However, numerous challenges face the implementation of traceability in the software engineering industry. Some of these challenges can be overcome through organizational policy and procedure changes, but the lack of cost-effective traceability models and tools remains an open problem. Many methods of implementing traceability exist, but each implementation method has its own limitations. A novel, cost-effective solution for the traceability tool problem is proposed, prototyped and tested in a case study using an actual aviation software project. Quantitative metrics from the case study are presented and a qualitative analysis is performed to demonstrate the viability of the proposed solution for the traceability tool problem. The results show that the proposed method offers significant advantages over implementing traceability manually or using existing commercial traceability approaches

Struktuurbeplanning in die Kaapprovinsie

In this paper those sections of the Land Use Planning Ordinance applic­able to structure plans are briefly mentioned and the 'Guide Lines for Structure Planning' as published by the Cape Provincial Administration are referred to, with emphasis on the different types of structure plans as identified by the CPA. Technical aspects which will play a crucial role in the successful implementation of the structure planning process, such as the multidisciplinary approach, ef­fective control over planning studies and a proper study design, are dealt with. Finally, problems associated with the practical implementation of structure plans and appropriate plan­ning approaches for smaller towns are discussed against the background of the 'Guide Lines'.*This article is written in Afrikaans

Light rail transit and its land use implications

Cost effective public transport systems that do not exert excessive negative impacts on the environment are needed in South Africa. Light rail transport is a mode that is not yet in South Africa, but which offers these possibilities. The concept of light rail is briefly touched by a discussion of the vehicle, its rail reserve and stops. The influence of light rail on land uses is discussed below. The Vancouver experience is discussed to indicate the influence of light rail on metropolitan level, and San Diego is treated as an example of this transport mode's impact on local land use. The structure plan for Atlantis (a new city with a planned population of 500 000 developed 45 km north of Cape Town) is discussed below. A transport study has indicated light rail as a suitable public transport system for this project. The transport study will be discussed briefly, after which the influence of the concept of light rail on the planned urban form and the development of the development will be explained

Beplanningskwessies van die 1990's

Met die aanvang van 1990 gaan ons 'n dekade binne wat groot nuwe uitdag­ings voor die deur van die Stads- en Streekbeplanningsberoep sal lê. Verste­deliking sal steeds groter druk op die omgewing, infrastruktuur en beskikbare kapitaalbronne plaas, terwyl stygende opvoedkundige standaarde 'n groter bewuswording van omgwingskwessies tot gevolg sal hê. Hierdie hoër opvoe­dingspeil sal ook daartoe lei dat die publiek toenemend op groter inspraak in die beplanningsproses sal aandring. Verstedeliking, die omgewing en gemeenskapsbetrokkenheid in die besluitnemingsproses kan as die belang­rikste beplanningskwessies van die volgende dekade beskou word. Hierdie kwessies is interafhanklik en meestal deel van dieselfde proses, maar word hier afsonderlik bespreek in 'n poging om die belangrikheid van elke element te beklemtoon

HOURS OF INFINITY: RECORDING THE IMPERFECT ETERNAL

Hours of Infinity is an ongoing project that seeks to record the “imperfect Eternal” – the human experience of the infinite, with all its flaws. A rigorously imprecise drawing method is at work in the three projects documented here, leading to visual objects that are uneven, absurd, and fragile symbols for something believed to be symmetrical, profound and everlasting. This MFA thesis documents the images, sounds, video, and performance event created thus far for Hours of Infinity. It also discusses the artistic, philosophical, and textual influences that fed directly into the creation of the work.Master of Fine Arts (MFA)School of Art & DesginUniversity of Michiganhttp://deepblue.lib.umich.edu/bitstream/2027.42/91760/1/2012_Kannenberg_MFA_Thesis.pd

Listening to Museums: Sounds as objects of culture and curatorial care

This practice-based project begins with an exploration of the acoustic environments of a variety of contemporary museums via field recording and sound mapping. Through a critical listening practice, this mapping leads to a central question: can sounds act as objects analogous to physical objects within museum practice – and if so, what is at stake in creating a museum that only exhibits sounds?Given the interest in collection and protection of intangible culture within contemporary museum practice, as well as the evolving anthropological view of sound as an object of human culture, this project suggests that a re-definition of Pierre Shaeffer’s oft-debated term ‘sound object’ within the context of museum practice may be of use in re-imagining how sounds might be able to function within traditionally object-based museum exhibition practices. Furthermore, the longstanding notion of ‘soundmarks’ – sounds that reoccur within local communities which help to define their unique cultural identity – is explored as a means by which post-industrial sounds such as traffic signals for the visually impaired and those made by public transport, may be considered deserving of protection by museum practitioners.These ideas are then tested via creative practice by establishing an experimental curatorial project, The Museum of Portable Sound (MOPS), an institution dedicated to collecting, preserving, and exhibiting sounds as objects of culture and human agency. MOPS displays sounds, collected via the author’s field recording practice, as museological objects that, like the physical objects described by Stephen Greenblatt, ‘resonate’ with the outside world – but also with each other, via their careful selection and sequencing that calls back to the mix tape culture of the late twentieth century.The unconventional form of MOPS – digital audio files on a single mobile phone accompanied by a museum ‘map’ and Gallery Guide – emphasizes social connections between the virtual and the physical. The project presents a viable format via which sounds may be displayed as culture while also interrogating what a museum can be in the twenty first centur

Curitiba, Brazil: A working example of sustainability within an urban context

The creation of sustainable environ­ments, i.e. environments which are self-supporting (or can be supported with available resources), is develop­ing into an important goal for the planning professions. In this paper, an attempt is made to motivate the need for this approach within the urban context. The city of Curitiba, Brazil, is then described as a working example of a city that has reached the point where it is function­ing in a sustainable way

Identifying Promising New Falcata Alfalfa Populations for use in Semiarid Rangelands

Alfalfa (Medicago sativa L.) is a valuable crop worldwide. In addition to its use as forage, the nitrogen fixation capabilities of root nodules make it a valuable component for improving soil health. Unfortunately, the semi-arid region of the Northern Great Plains introduces a number of environmental stresses that are detrimental to stand establishment and persistence. The ability to produce adventitious shoots from roots is generally considered a favorable trait for increasing stress resistance. This study aimed to identify alfalfa populations possessing the ability to produce adventitious shoot from root segments. Seven Plant Introductions (PIs), selected from the National Plant Germplasm System, and one commercial cultivar (Persist II) were evaluated. Two 6cm root segments originated at 1cm and 7cm below the cotyledonary node from 1-year-old plants. Root segments were planted in Miracle-Gro® potting soil for 16 weeks. Adventitious shoot emergence was recorded throughout the experimental period. At the end of the experimental period, a number of root segments that produced adventitious shoots, shoot survival, status of flowering and non-shoot-bearing root segment decay were determined. Six of the seven PIs produced adventitious shoots. No shoots produced on Persist II and PI 494662 roots. Among the six populations, frequency of generating adventitious shoots from roots ranged from 3.8% to 57% and frequency of shoot survival varied from 33% to 100%. Speed of regeneration from roots and viability of root segments in soil varied among populations. PI 631678 had the greatest frequency and speed of regeneration from roots, high survival and flowering frequencies. Little difference in adventitious shoot regeneration and survival related to distance below the cotyledonary node within the same populations
