The thesis is aimed at Gantt charts. Primarily on their use in production processes, such as planning and scheduling. The thesis also includes an introduction, explaining what are the Gantt charts, for what are using and what is their principle. The thesis also includes analysis and software possibilities for implementing Gantt charts with using OOP. Programmatic and theoretical analysis of the various functions that are characteristic of Gantt charts, including their internal logic and program implementation. These programmed characteristic functions of Gantt charts were composed in the form of a DLL library, which provides a simple implementation of Gantt charts. By using this library is realized the software for production management. The work is included on the DVD, except the DLL itself software with detailed descriptions of each part of the source code.

Developing process plans and part programs rapidly and correctly for CNC machine tools plays a vital role in manufacturing. This study is concerned with the development of a web-enabled virtual design and manufacturing application system for rotational parts. The object oriented methodology is used in the application development. Windows Distributed interNet Application (DNA) architecture which describes a framework of building software technologies in an integrated web and client-server model of computing, is employed in the system. The entire system was modeled with Unified Modeling Language (UML), which is an industry-standard visual modeling notation to express software development architectures. Feature-based design approach, being a practical way of linking the design with manufacturing, is implemented in the rotational part design. Users have to be registered in order to use the system. With the supplied web site, users can easily register to system. After registration, the user obtains a password and a unique username. Upon the user authentication, the user session starts. A typical user session involves new or past project selection, material selection, part sketching, blank size definition and cutting parameters determination. After all the steps are completed, process plan and part-program, which are required to manufacture the part on Denford Mirac CNC Turning Machine are generated and displayed on the web site and then saved to the database. The application enables the users to see past projects and to generate new process plan and part programs for different cutting parameters. The process plan, part program and the 2D wire frame drawing of the corresponding part are demonstrated on the web site for the chosen projects.

Child-friendly spaces are not successfully implemented in South Africa due to problems such as urbanization, development pressure, lack of qualitative open spaces and lack of policy and legislation guiding the planning and protection of such spaces. This study evaluates local and international planning approaches of childfriendly spaces in an attempt to identify best practices and explore how child-friendly spaces can be planned and utilized locally, in South Africa, (especially rural areas such as the Vaalharts district in the North West Province) to develop playful, educational, environmentally preserving and qualitative child-friendly spaces.The research methodology used in this study consist of (i) a literature investigation on concepts of child-friendly environments, qualitative open spaces, rural challenges, as well as current child-friendly policy and legislation, both from an international and local perspective; and (ii) an empirical study, conducted qualitatively by means of Pilot testing and case study evaluation. Local pilot tests were limited, due to a lack of child-friendly spaces in South Africa to, proposed Valhalla Water Park in Cape Town and Irene Village Mall in Pretoria. The case study evaluation consists out of Green Point Urban Park and the Vaalharts Water Innovation Project that is a newly planned, “still in progress”, project. International case studies included examples of successful child-friendly spaces such as La Louviere in Belgium, Chapefield play area and Darnley Park in Scotland, Play Field Farnborough in England, Caronport Spray Park in Canada and Bellevue Redmond Spray Park in Washington. Based on the findings, recommendations are made in terms of the planning and development of child-friendly spaces, incorporating examples such as the provision of spray parks in rural areas in order to create playful, educational, environmentally preserving and qualitative outdoor spaces. / MArt et Scien (Urban and Regional Planning), North-West University, Potchefstroom Campus, 2014

The analysis is made in the context of object-oriented programming evolution. The survey is made on miscellaneous assumptions related to explicit role modeling and separation of system state and behaviour concerns in software development. The parts of software development process which have a lack of role modeling techniques are identified in this thesis. The suggestions of solutions to classic object-oriented programming behaviour modeling problems for software construction phase are made. Finally, the recommendations related to role modeling for software development process modification are made to support all the development phases.

The practice of sequential testing is followed by the evaluation of accuracy, but often not by the evaluation of cost. This research described and compared three sequential testing strategies: believe the negative (BN), believe the positive (BP) and believe the extreme (BE), the latter being a less-examined strategy. All three strategies were used to combine results of two medical tests to diagnose a disease or medical condition. Descriptions of these strategies were provided in terms of accuracy (using the maximum receiver operating curve or MROC) and cost of testing (defined as the proportion of subjects who need 2 tests to diagnose disease), with the goal to minimize the number of tests needed for each subject while maintaining test accuracy. It was shown that the cost of the test sequence could be reduced without sacrificing accuracy beyond an acceptable range by setting an acceptable tolerance (q) on maximum test sensitivity. This research introduced a newly-developed ROC curve reflecting this reduced sensitivity and cost of testing called the Minimum Cost Maximum Receiver Operating Characteristic (MCMROC) curve. Within these strategies, four different parameters that could influence the performance of the combined tests were examined: the area under the curve (AUC) of each individual test, the ratio of standard deviations (b) from assumed underlying disease and non-disease populations, correlation (rho) between underlying disease populations, and disease prevalence. The following patterns were noted: Under all parameter settings, the MROC curve of the BE strategy never performed worse than the BN and BP strategies, and it most frequently had the lowest cost. The parameters tended to have less of an effect on the MROC and MCMROC curves than they had on the cost curves, which were affected greatly. The AUC values and the ratio of standard deviations both had a greater effect on cost curves, MROC curves, and MCMROC curves than prevalence and correlation. The use of BMI and plasma glucose concentration to diagnose diabetes in Pima Indians was presented as an example of a real-world application of these strategies. It was found that the BN and BE strategies were the most consistently accurate and least expensive choice.

Life Cycle Assessment (LCA) is the globally the most recognised method for quantifying theimpact the a product or service has on the environment through its whole life-span. Theconstruction sector plays a key role in the depletion of the natural resources and the energyconsumption on the planet. Thus it is fundamental that an environmental assessment tool likeLCA should be in close cooperation with the construction process.This thesis focuses on the environmental impact of bridge abutments, and can be divided in twoparts.The rst one focuses on enhancing the automated design in the construction eld. A Python codeis created that focuses on creating the geometry of any type of bridge abutment and conductingthe calculations for the required concrete and reinforcement. The process is attempted to becomecompletely automated.The second part introduces three alternative designs for a bridge abutment that attempt to havethe same structural properties and cooperate successfully with the superstructure, while at thesame time utilize as little material as possible. The possible reduction in material is quantiedin environmental terms after an environmental impact assessment is performed.The results show that dierent designs can have a great impact on the reduction on the materialconsumption and on the impact that the whole structure has on the environment. The resultsin this study might provide the designers with valuable motivation and guidelines to achievehigher sustainability standards in the future.

This independent work includes refactoring a website application. In simpler sense, it means modernizing existing code by increasing its quality and making it more understandable; to exchange old knowledge of methods and concepts into something that is more relevant to its time. This refactoring has also meant to transform the UI into something that is more appealing, and more userfriendly. The website that has gone through the refactoring is Nordyr (”https://nordyr.com/”). Nordyr is a Nordic Film & Series Database that shares information about Nordic films and tv-series, and everyone involved. They also offer social tools such as user profiles and various tools to simplify the exploration and interaction between Nordic movies and consumers. This was made possible by using vanilla PHP, JavaScript/jQuery, and the MariaDB database for information storage and management. The implementation of the refactoring meant retaining PHP for the backend, but applying the Laravel framework, and likewise for JavaScript, but applying ReactJS (a powerful JavaScript library). Nordyr retains MariaDB for its information storage and management, however, its SQL queries have been adapted to Laravel’s query-builder and Eloquent ORM, which means that the majority of SQL queries have been rewritten and the majority of data tables are now represented by models. The restructuring of Nordyr has shown that the website now has the ability to scale better, and the development environment will also be more pleasant for those involved. / Det här självständiga arbetet har innefattat att omstrukturera en hemsida. Det innebär i enklare mening att modernisera kod och öka dess kvalité; att byta ut äldre kunskaper om metoder och koncept till något som anses vara av mer relevans för sin tid. Refaktoreringen har också inneburit att dess UI gjorts om till att bli mer tilltalande och användarvänlig. Hemsidan som gått igenom refaktoreringen är Nordyr (”https://nordyr.com/”). Nordyr är en Nordisk Film- & Serie-databas som delar information om nordiska filmer och tv-serier och alla inblandade. De erbjuder även sociala verktyg som användarprofiler och diverse verktyg för att förenkla upptäckandet och interaktionen mellan nordiska titlar och konsumenter. Detta gjordes möjligt med hjälp av vanilj PHP, JavaScript/jQuery, och databasen MariaDB för informationslagring och hantering. Genomförandet av refaktoreringen innebar att behålla PHP för backend men tillämpa ramverket Laravel, och likaså för frontend, JavaScript stod kvar men ReactJS (”JavaScript bibliotek”) tillämpades. Nordyr behåller MariaDB, men dess förfrågningar i SQL har anpassats till Laravels query-builder och Eloquent ORM, vilket innebar att majoriteten av SQL frågor skrivits om och majoriteten av tabeller representeras nu av modeller (”Models”). Omstruktureringen av Nordyr har visat på att hemsidan nu har förmågan att skala bättre, och utvecklingsmiljön kommer även bli mer behaglig för de inblandade.

As programs continue to increase in size, it has become increasingly difficult to separate concerns into well localized modules, which leads to code tangling- crosscutting code spread throughout several modules. Thus, Aspect-Oriented Programming (AOP) offers a solution to creating modules with little or no crosscutting concerns. AOP presents the notion of aspects, and demonstrates how crosscutting concerns can be taken out of modules and placed into a centralized location. In this paper, a taxonomy of aspect-oriented programming, as well as a basic overview and introduction of AOP, will be presented in order to assist future researchers in getting started on additional research on the topic. To form the taxonomy, over four-hundred research articles were organized into fifteen different primary categories coupled with sub-categories, which shows where some of the past research has been focused. In addition, trends of the research were evaluated and paths for future exploration are suggested.
