A Needs-Ictd Strategy Alignment Foundation For The Measurement Of Ictd Impact: Three Case Studies In South Africa, Gugulethu Q. Baduza, Caroline P. Khene

The African Journal of Information Systems

Access to ICTD projects has increased over the years; however, they have not significantly changed the lives of the targeted communities. This discrepancy relates to the gap that exists between the reality of the community, its needs and the ICTD strategy of the project. This research paper presents a Needs-ICTD strategy alignment framework to support the alignment of ICTD strategy, and the development and promotion of contextual needs of marginalized areas. The framework also contributes to the identification of preliminary impact indicators, which can support impact assessment. Through a multi-case study investigation of the Siyakhula Living Lab and the SAP ...

In order to construct a closed-loop system, a scaled three storey building was designed and built according to the scaling laws, and then four MRE isolator prototypes were fabricated and utilised to isolate the building from the motion induced by a scaled El Centro earthquake. Fuzzy logic was used to output the current signals to the isolators, based on the real-time ...


Development Of A Novel Phase Change Material Emulsion For Cooling Systems, Jingjing Shao, Jo Darkwa, Georgios Kokogiannakis Jan 2016

Development Of A Novel Phase Change Material Emulsion For Cooling Systems, Jingjing Shao, Jo Darkwa, Georgios Kokogiannakis

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, a novel phase change material emulsion (PCE-10) consisting of an organic PCM (RT10) and water has been developed. Its thermophysical properties such as heat of fusion, viscosity and sub-cooling temperature have been established. The chemical stability during both storage and discharge periods have also been evaluated. The results indicate low sub-cooling temperature and relatively long period of stability without any sign of segregation but the viscosity was found to be much higher than that of water.Further improvement and experimental studies into its flow characteristics are therefore being encouraged.

Development Of An Mre Adaptive Tuned Vibration Absorber With Self-Sensing Capability, Shuaishuai Sun, Jian Yang, Weihua Li, Huaxia Deng, Haiping Du, Gursel Alici

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, self-sensing technology was introduced into an adaptive tuned vibration absorber, incorporating a laminated magnetorheological elastomer (MRE) structure, a hybrid magnetic system and a self-sensing component. The adoption of the laminated MRE structure and the hybrid magnetic system enables the absorber to have higher lateral flexibility and a wider effective frequency range. The integration of the self-sensing capability allows the absorber to operate without sensors and, at the same time, greatly reduces costs, required space and maintenance. A series of experiments were conducted to measure the frequency shift property, to verify the self-sensing capability and to evaluate its ...

Dependence Of Texture Development On The Grain Size Of Tertiary Oxide Scales Formed On A Microalloyed Steel, Xianglong Yu, Zhengyi Jiang, Jingwei Zhao, Dongbin Wei, Ji Zhou, Cunlong Zhou, Qingxue Huang

Faculty of Engineering and Information Sciences - Papers: Part A

Both orientational and geometrical characteristics of grains in tertiary oxide scales have been quantitatively investigated using the electron backscatter diffraction (EBSD) technique. Phase and orientation mappings demonstrate that the {001} planes of magnetite and the {0001} planes of hematite are parallel to the direction of oxide growth. Pole figures (PFs) as scattering plots clearly display the direct correlation between the orientations and microstructure sites of magnetite grains. Magnetite grains develop a strong rotated cube texture component that shifts to the {100} component, whereas those with the grain size of 1-5. μm develop the {001} cube texture component. The refined magnetite ...


Learning From Cinara: Exploring The Depths Of Participatory Water Engagement In Cali, Colombia, Zachary T. Strickland Jan 2015

Learning From Cinara: Exploring The Depths Of Participatory Water Engagement In Cali, Colombia, Zachary T. Strickland

University Honors Program Theses

Located within the Universidad del Valle in Cali, Colombia, CINARA is an academic institution, comprised of both engineers and social scientists, that has almost three decades of experience regarding participatory approaches to water supply and environmental sanitation. In this paper, I argue that CINARA’s work is important due to its emphasis on meaningful community participation that significantly involves communities in decisions on technical matters that are usually allocated exclusively to “experts.” Furthermore, the valuation of social considerations and non-technical knowledge found amongst CINARA’s engineers stands in distinct contrast to traditional development practices and engineering mindsets. This paper will ...

Interpreting, Stephanie Jo Kent May 2014

Interpreting, Stephanie Jo Kent

Doctoral Dissertations

What do community interpreting for the Deaf in western societies, conference interpreting for the European Parliament, and language brokering in international management have in common? Academic research and professional training have historically emphasized the linguistic and cognitive challenges of interpreting, neglecting or ignoring the social aspects that structure communication. All forms of interpreting are inherently social; they involve relationships among at least three people and two languages. The contexts explored here, American Sign Language/English interpreting and spoken language interpreting within the European Parliament, show that simultaneous interpreting involves attitudes, norms and values about intercultural communication that overemphasize information and ...

Nets Or Vaccines: Malaria Vaccine Research, David Ernenwein Jan 2014

Nets Or Vaccines: Malaria Vaccine Research, David Ernenwein

Pepperdine Policy Review

The global battle against malaria has seen many victories in the developed world but the undeveloped world and particularly Africa continue to suffer from this disease. The development of the RTS,S vaccine and ongoing research into additional vaccines have been touted as the solution to the crisis. However, the news of the successful RTS,S trial should be viewed with caution. Concerns over the effectiveness of the existing vaccine and the cost of further development may not be justified, especially given the known effectiveness of current treatment methods. This research must be watched carefully lest the allure of the ...


Aligning Ontology-Based Development With Service Oriented Systems, Jun Shen, Ghassan Beydoun, Graham Low, Lijuan Wang Jan 2014

Aligning Ontology-Based Development With Service Oriented Systems, Jun Shen, Ghassan Beydoun, Graham Low, Lijuan Wang

Faculty of Engineering and Information Sciences - Papers: Part A

This paper argues for placing ontologies at the centre of the software development life cycle for distributed component-based systems and, in particular, for service-oriented systems. It presents an ontology-based development process which relies on three levels of abstraction using ontologies: architecture layer, application layer and domain layer. The paper discusses the key roles of ontologies with respect to the various abstraction layers and their corresponding impact on the concomitant workproducts. In addition, a peer-to-peer-based service selecting and composing tool is suggested as a way of supporting the process. The paper presents the architecture of the proposed tool and illustrates the ...


Development Of Databases For Facilitating Green Roof Energy Simulation Assessments, Aloysius Decruz, Georgios Kokogiannakis, Jo Darkwa, Kate Yuan, Paul Strachan Jan 2014

Development Of Databases For Facilitating Green Roof Energy Simulation Assessments, Aloysius Decruz, Georgios Kokogiannakis, Jo Darkwa, Kate Yuan, Paul Strachan

Faculty of Engineering and Information Sciences - Papers: Part A

Assessments of the energy performance of green roofs have traditionally been performed with experimental and modelling procedures. Experimental green roof energy studies have significant disadvantages (expensive, time-consuming, cannot be generalised, etc.). On the other hand, modelling studies are often done with over-simplified models (for example, by ignoring the effect of moisture flows in the green roof layers) or with detailed models that require inputs which are often difficult to be obtained in practice and may involve a certain degree of uncertainty. This paper describes the methodologies for the development of databases that include data inputs that could be used within ...

Shuttle Car Network For Roadway Development, Dalin Cai, Ernest Baafi, Ian Porter

Faculty of Engineering and Information Sciences - Papers: Part A

Australian underground coal mines predominately use the longwill method for coal extraction. In longwall mining at least two parallel roadways known as gateroads are mined to delineate the sides of the longwall block, a longwall installation face is then driven connecting the gatheroads to enable the longwall mining equipment to be installed. Roadway development should ideally be ahead of the longwall so that the longwall equipment can be installed into the newly developed panel with minimal delay to coal production. A discrete event mode of roadway development can help asses how a particular configuration may perform with high levels of ...


Development And Validation Of A Disaster Management Metamodel (Dmm), Siti Hajar Othman, Ghassan Beydoun, Vijayan Sugumaran Jan 2014

Development And Validation Of A Disaster Management Metamodel (Dmm), Siti Hajar Othman, Ghassan Beydoun, Vijayan Sugumaran

Faculty of Engineering and Information Sciences - Papers: Part A

Disaster Management (DM) is a diffused area of knowledge. It has many complex features interconnecting the physical and the social views of the world. Many international and national bodies create knowledge models to allow knowledge sharing and effective DM activities. But these are often narrow in focus and deal with specified disaster types. We analyze thirty such models to uncover that many DM activities are actually common even when the events vary. We then create a unified view of DM in the form of a metamodel. We apply a metamodelling process to ensure that this metamodel is complete and consistent ...
