Timing Skew

We examine two aspects specific to complex data fusion algorithms in integrated strapdown inertial navigation systems aided by global positioning systems, with their inherent spatial separation between the GNSS antenna phase center and the inertial measurement unit, as well as with the timing skew between their measurements. The first aspect refers to modifications of mathematical models used in INS/GNSS integration. The second one relates to our experience in their application in onboard airborne navigation algorithms developed by Moscow Institute of Electromechanics and Automatics.

Widespread Dissemination

In response to frequent flooding disasters due to local torrential downpours, the Japanese Meteorological Agency (JMA), along with other organizations, has advanced rapid tracking systems for torrential rains. It is also noted that people can now be easily located by the widespread dissemination of mobile phones and car navigation systems with easy-to-use global positioning systems (GPS). Unfortunately, the current practice of disseminating disaster information has failed to incorporate recent these technological innovations. In this paper, we propose a way to establish a new information dissemination media called “micromedia,” which provides individuals with disaster prevention information in real time, regardless of their location.

Implementation Problems

AbstractSouth Africa has utilised intermediaries to protect child witnesses and assist their communication in criminal proceedings in the magistrates' courts since 1993. is article examines some lessons to be learned from the South African experience. It provides an overview and assessment of attempts to overcome implementation problems and develop the legislation providing for intermediaries. It reviews contradictory solutions for improvement of the law recently put forward by the high court and constitutional court. Applying both the South African history and international standards, we argue that the high court offered a better way forward. We suggest some additional reforms which may also be relevant for advocates of the intermediary system in other jurisdictions.

And Training

On paper, South African law concerning detention of asylum seekers appears consistent with international standards. However, the text of the Act is vague and overly broad, permitting interpretations inconsistent with international human rights standards. Further, in practice, officials often fail to uphold even the lowest standards of the Act, in violation of South African law. In order to protect the rights of asylum seekers, the South African government should institute formal guidelines and training programs, as well as a system of strong supervision and accountability, to ensure that the Act and Regulations are interpreted in a manner consistent with international law. Such a step will enable South Africa to live up to its noble post-apartheid human rights ideals.

South Africa has one of the highest inmate populations in the world. In order for the South African Correctional Services system to provide an environment conducive for the appropriate rehabilitation and reformation of its many inmates, it requires a balanced prisoner-warder ratio based on international standards. But is this the case in South African prisons? This is one of the questions that this article engages as it examines the prisoner-warder ratio at the East London Maximum Correctional Centre (ELMCC) in an effort to understand the effects of prison overcrowding on the prison work environment and correctional personnel. Based on empirical evidence gathered through qualitative techniques, the study finds a disproportionate prisoner-warder ratio at the ELMCC. This disproportion has a number of negative effects on the prison work environment and direct security personnel on duty. For example, high absenteeism is rife with warders frequently on sick leave while others are regularly on temporary incapacity leave. High stress levels are also a major problem pushing many warders into alcohol abuse. Cognitive job satisfaction and organizational commitment are also negatively affected by this disproportion with the majority of warders indicating poor work performance due to low morale and lack of motivation.

In the past few years, a number of ideas have been proposed for indoor navigation systems. These ideas were not as widely implemented as outdoor positioning systems like GPS(Global Positioning Systems). We propose an indoor navigation assistance system using Bluetooth which is low cost and feasible to use in daily life. Our system enables users with handheld mobile devices to steer with ease through the indoor premises using the short range radio frequencies of Bluetooth. It also establishes user’s current location and the various paths leading to the destination. Dijkstra’s algorithm is used to determine the shortest path from the source to the required destination.

Labour markets across the world have in recent years been characterised by instability and scare employment opportunities. Despite the fact that the 21st century has carried with it massive technological change and a rise in the significance of education for better employment prospects, it has moreover brought about expanded vulnerability which has neglected to ensure employment for work-searchers. For those who want to work, the inability to find employment has been a source of enormous adversities both personally and economically. This is not unique to South Africa as the country is plagued with very high unemployment rates across all age categories and continually rising numbers of discouraged work-seekers. Although unemployment indicators have to a great extent followed international standards, the failure to incorporate those who have abstained from searching has inadvertently contributed to a lack of understanding regarding the nature of discouragement in the labour market.

Property Valuation

Ethical issues and standards of property professions are being scrutinised. To date, no research has been carried out on the ethical standards in the property valuation profession in South Africa. This research compared the content of codes of ethics and professional conduct of the South African property valuation profession to international standards, and investigated the ethical standards and moral values held by registered valuers in South Africa. A self-administered survey, administered to 611 professional and professional associate valuers, was used. It measured five constructs of unethical behaviour layered into a survey adapted from Hoyt, Wright and Croft (2002). No statistically significant differences were found between different demographic factors in the ethical beliefs of South African valuers. A literature review comparing South Africa’s codes of conduct with those in the United States of America, Australia and New Zealand showed that the standards of ethics and professional practice in South Africa are not in line with international standards. South African valuers appear to be ethical and resist external pressures which could lead to unethical behaviour.

Address Data

Abstract. Addresses are essential for disaster risk management and response because they are used to locate people affected by a disaster or at risk of being affected. South Africa is vulnerable to disasters, however, despite a legislative framework for supporting disaster risk management that meets international standards, implementation falls short due to underfunding, poor interdepartmental coordination and lack of political support. The importance of cross jurisdictional address data was highlighted by the COVID-19 pandemic of 2020 when the geocoding of positive cases was hindered due to the lack of such address data in South Africa. In this paper, we present first results about a cloud-based tool for integrating address data from multiple municipalities into a single address dataset that conforms to the South African National Standard, SANS 1883-2:2017, Geographic information – Addresses: Part 2: Address data exchange. We reviewed and evaluated three cloud platforms for the prototype implementation. The integrated dataset is maintained in the cloud and therefore readily accessible by relevant organizations. At the same time, processing in the cloud can handle changing volumes of data with elasticity, i.e. computing power can be increased or decreased at short notice, as necessary during a disaster response. Furthermore, processing can be automated, thereby mitigating the risk of reduced manpower due to a disaster. Overall, a properly maintained cloud-based tool can result in more efficient use of resources presenting a viable and interesting alternative for underfunded disaster risk management centres in South Africa and other parts of the world.
