Phiri, Lighton. "Investigating the Impact of Organised Technology-driven Orchestration on Teaching." Thesis, University of Cape Town, 2018. http://pubs.cs.uct.ac.za/archive/00001263/.

Full text

Abstract:

Orchestration of learning involves the real-time management of activities performed by educators in learning environments, with a particular focus on the effective use of technology. While different educational settings present unique problems, the common challenges have been noted to primarily be as a result of multiple heterogeneous activities and their associated intrinsic and extrinsic constraints. In addition to these challenges, this thesis argues that the complexities of orchestration are further amplified due to the ad hoc nature of the approaches and techniques used to orchestrate lea

Abstract:

The digital Bleek and Lloyd Collection is a rare collection that contains artwork, notebooks and dictionaries of the earliest habitants of Southern Africa. Previous attempts have been made to recognize the complex text in the notebooks using machine learning techniques, but due to the complexity of the manuscripts the recognition accuracy was low. In this research, a crowdsourcing based method is proposed to transcribe the historical handwritten manuscripts, where volunteers transcribe the notebooks online. An online crowdsourcing transcription tool was developed and deployed. Experiments were

Full text

Abstract:

Many measurements in cosmology depend on the use of integrated distances or time, but. galaxies evolving passively on a timescale much longer than their age difference allow us to determine the expansion rate H(z) solely as a function of the redshift-time derivative dz/dt. These model-independent "cosmic chronometers" can therefore be powerful discriminators for testing different cosmologies. In previous applications, the available sources strongly disfavored models (such as Lambda CDM) predicting a variable acceleration, preferring instead a steady expansion rate over the redshift range 0 les

A comparative study was performed to identify personal characteristics and motivation of volunteer leaders from two youth groups; 4-H and Campfire. Criteria under study were appraised using questionnaires. Data analysis based on the responses obtained from 64 volunteer leaders. The personal characteristics investigated included expected period of service, support and encouragement, time spent on volunteer activities, satisfaction from service rendered, enrollment of volunteer leaders children, place of residence, length of residence, educational level, employment status, age, gender, and ethni

Abstract:

Energy usage has become an important issue in wireless communication systems. The energy-intensive nature of wireless communication has spurred concern over how best systems can make the most use of this non-renewable resource. Research in energy-efficient design of wireless communication systems show that one of its challenges is that the overall performance of the system depends, in a coupled way, on the different submodules of the system i.e. antenna, power amplifier, modulation, error control coding, and network architecture. Network architecture implementation strategies offer protocol so

Abstract:

News interviews are core within current practices of journalism. They point to the existence of a mediated public space and bolster the concept of democratic accountability. This research investigates what impact these concepts have on the news interviews broadcast by the Today programme (BBC Radio 4) and how interaction within them invoked the public. The programme has a responsibility to uphold the democratic life of the UK, making it a compelling focus of research. The case study examined in this thesis is the broadcast of news interviews concerning the Human Fertilisation and Embryology Ac

Abstract:

Open access and open resources have gained much attention from the world in the last few years. The interest in sharing information freely by the use of the World Wide Web has grown rapidly in many different fields. Now, information is available in many different data forms because of the continuous evolution in technology. The main objective of this thesis is to provide content creators and educators with a solution that simplifies the process of depositing into digital repositories. We created a desktop tool named ORchiD, Open educational Resources Depositor, to achieve this goal. The tool e

Abstract:

The next-generation of radio interferometer arrays - the proposed Square Kilometre Array (SKA) and its precursor instruments, The Karoo Array Telescope (MeerKAT) and Australian Square Kilometre Pathfinder (ASKAP) - will produce radio observation survey data orders of magnitude larger than current sizes. The sheer size of the imaged data produced necessitates fully automated solutions to accurately locate and produce useful scientific data for radio sources which are (for the most part) partially hidden within inherently noisy radio observations (source extraction).

Abstract:

Profound changes in higher education induced by the reforms of the New Public Management (NPM) have led to administrative growth, professionalism, managerialism, and higher relevance of the economic principle. As a further consequence, the importance of the organizational perspective has increased. Thus, questions about effective organizational structures and their design frameworks have become more crucial. The contingency approach provides insights into these questions because it investigates the effectiveness of organizational structures in different situations. Based on expert interviews w

Gleichzeitig mit diesem rasanten Datenwachstum und resultierend aus den technologischen Fortschritten verändert sich auch die zur Darstellung und Speicherung von digitalen Daten notwendige Hard- und Software. Dies führt zu der Situation, dass Daten in großen Mengen beinahe beiläufig erzeugt werden, w

Abstract:

This thesis examines so called folding neural networks as a mechanism for machine learning. Folding networks form a generalization of partial recurrent neural networks such that they are able to deal with tree structured inputs instead of simple linear lists. In particular, they can handle classical formulas - they were proposed originally for this purpose. After a short explanation of the neural architecture we show that folding networks are well suited as a learning mechanism in principle. This includes three parts: the proof of their universal approximation ability, the aspect of informatio

Abstract:

Adaptability and flexibility are some of the most important human characteristics. Learning based on new experiences enables adaptation by changing the structural connectivity of the brain through plasticity mechanisms. But the human brain can also adapt to new tasks and situations in a matter of milliseconds by dynamic coordination of functional activation. To understand how this flexibility can be achieved in the computations performed by neural networks, we have to understand how the relatively fixed structural backbone interacts with the functional dynamics. In this thesis, I will analyze
