Configurable Random Instruction Generator for RISC Processors

Processors have evolved and grown more complex to serve enormous computational needs. Even though modern-day processors share same dna with processors half century ago, verifying them today is the huge wall to scale. Verification dominates production cycle even with advances both in software (programming as well as CAD tools) and manufacturing (fabrication) as there are too many test scenarios to cover. Testing complex devices like processors with manual-testing alone in certainty missing the dead lines. Automatic verification is a great way to overcome hurdles of manual testing viz. speed, manpower, and ultimately cost. The work described in this paper targets verification of processors which have in-order instruction execution. Verification is done using SystemVerilog testbench which compares output of device under test to the output of SystemC model, when random instructions are applied

Experiences African domestic workers undergo as a result of sending their children to predominantly white schools

Sending African children to white schools brings about potential problems for all parties involved. However, the complications are more pronounced in situations where the child's mother is a domestic worker and the employer assumes an active role in the child's education. One such case triggered this research. Based on that particular case, the aim of this study was to explore experiences and feelings of African domestic workers with children in white schools

Developing a Corporate Governance Regime for State Owned Enterprises in Papua New Guinea

Papua New Guinea (PNG) has a developing economy and the Government controls three quarters of it. Control, in a way, provides the Government with power to give effect to the aspirations of the people enshrined in the National Goals and Directive Principles. State Owned Enterprise (SOE) is one of the means that the Government utilizes to participate in the economy, particularly delivering goods and services to the people. SOEs are established as separate legal entities and intended to be independent of the government so that they can be efficient and/or profitable, replicating the private sector, in their role in production of goods and delivery of services. There is a principal and agent relationship in an SOE. On the one hand the government is a shareholder with multiple interests, including public interest considerations and on the other hand there is the management that is responsible for strategic decisions and operations, creating a principal and agent relationship. The important question in this relationship is to what extent the government, as principal, should be involved in the business and affairs of SOEs. The use of SOEs by government creates controversies. Since Independence in 1975, SOEs have been increasingly facing problems in corporate governance. Some of the problems identified in PNG include situations where procedures are not complied with in appointing and terminating directors and chief executive officers (CEOs), most of which end up in court; responsible ministers, directors or CEOs involved in self-interested activities; and appointment of political associates and family members as directors and managers who do not have skills, knowledge or experience. These are issues in corporate governance; however they are not looked at from that perspective because corporate governance is a new concept that has never been substantively discussed in PNG. Thus, this study examines and records the law and practice of corporate governance, and identifies deficiencies and ways in which the corporate governance regime in SOEs can be improved. Given the fact that corporate governance is a new phenomenon in PNG, the thesis made use of case study methodology. There were five SOEs selected for case studies. Two are under the category of statutory corporation and three under state company. These SOEs were selected for purposes of comparing and contrasting under their individual category and between the two categories. The data was collected through documents and semi – structured interviews. The participants in the interviews were senior managers, former and current directors and CEOs, and consumers of SOEs. The research found many flaws of corporate governance in SOEs. These flaws were the consequence of lack of understanding and appreciation of corporate governance. Further, they were the consequence of inconsistencies between different laws, between laws and the practice, and deficiencies in the laws. The result of the research suggests first that the Government controls SOEs and is involved in both operational and policy matters of SOEs. Second, boards of SOEs are ineffective. Nearly all directors are on a part-time basis and lack understanding of the business and affairs of SOEs and their own roles and responsibilities. Third, the role of public institutions such as Ombudsman Commission and Public Accounts Committee is unclear among the participants interviewed. Consequently, the Government that controls SOEs is not held to account for its conduct in relation to them. Finally, the majority of consumers from each SOEs interviewed, stated that the quality and efficiency of services in SOEs are poor. This can partly be related to lack of good corporate governance

Analysing the Role of Good Corporate Governance in TVET Colleges in South Africa

The main purpose of the study was to analyse the role of good corporate governance in TVET colleges in South Africa (SA).The study employed qualitative methods using secondary data from various credible publications. From a theoretical perspective, the study discovered that, corporate governance plays a pivotal role in TVET colleges to certify equal treatment of shareholders,  integrity and business ethics, conflict resolution, accountability and transparency in all spheres of their operations and leadership. In the same vein, empirical studies examined indicated that, TVET colleges face a myriad of challenges such as lack of effective leadership and sound administration; inadequate and misappropriation of funds as well as weak accountability. Furthermore, TVET colleges also experience inadequate and substandard infrastructure and insufficient equipment thus inter alia. The study recommends that, TVET colleges in SA should leverage on compliance with  good corporate governance principles both internally and externally as contained in the King’s reports of corporate governance. It emerged from the study that, TVET colleges should develop code of practice in line with the CET Act. Likewise, TVET colleges must consider training in King codes and other relevant governance codes so as to reap fully the rewards of good corporate governance within their space.

A Simple Computational Model for Acceptance/Rejection of Binary Sequence Generators

A simple binary model to compute the degree of balancedness in the output sequence of LFSR-combinational generators has been developed. The computational method is based exclusively on the handling of binary strings by means of logic operations. The proposed model can serve as a deterministic alternative to existing probabilistic methods for checking balancedness in binary sequence generators. The procedure here described can be devised as a first selective criterium for acceptance/rejection of this type of generators.Comment: 16 pages, 0 figure

PERSONNEL MANAGEMENT AND JOB ANALYSIS IN ACADEMIC LIBRARIES OF HARYANA: A STUDY

This study shows how human resource management may assist a company reach its goals and objectives by allowing each person to contribute their creativity and productivity to its success. Leadership and human resource management (HRM) are two ideas that are regularly utilized to understand better how to manage people in any organization. In the library, human resource management (HRM) is defined as coordinating all resources by performing a range of interrelated responsibilities such as planning, staffing, organizing, directing, and controlling. In this study, data was collected via Google form from 55 authorized library personnel, yielding a response rate of 73.3 percent out of 75 respondents, which is sufficient. In addition, Excel was used to analyse and interpret the data. After reviewing the findings of this study, researchers discovered that personnel management is critical in both library and other professions. Therefore, personnel management, job analysis, and HRM conditions among library professionals are defined in this study

A Case of Celiacomesenteric Trunk in a Tanzanian Man.

Variation in the branching patterns of the three major arteries that supply the digestive system may occur due to different embryological mechanisms. The present case report describes the celiac artery and the superior mesenteric artery originating from the abdominal aorta through a common trunk. The celiac artery in turn gave rise to the splenic artery and a common trunk for common hepatic and left gastric artery. The superior and inferior mesenteric arteries had normal branching patterns. Awareness of these variations on the part of the surgical team before surgery can help avoid iatrogenic arterial injury

A Real Time operation and Control of Devices using Power Line Communication

In order to improve the ef?ciency and reliability of power delivery, Future Smart Grid systems will intelligently monitor and control energy ?ows. This monitoring and control requires highly reliable communication between customers, local utilities and regional utilities and also low-delay. A vital part of future Smart Grids is the two-way communication links between smart meters at the customer sites and a (decentralized) command and control center operated by the local utility. Narrowband power line communication (PLC) systems operating in the 3-500 kHz band are attractive to enable these two-way communication links because they can be deployed over existing outdoor power lines. However, Power lines, have traditionally been designed for unidirectional power delivery and remain hostile environments for communication signal propagation. In this article, with the use of PLC systems we review signal processing approaches to model channel impairments and impulsive noise and mitigate their effects in narrowband PLC systems. We will study the ways to improve the communication performance based on emerging standards and current

Supervision Practices as a Predictor of Maritime Accidents and Incidents in Territorial Waters, Mombasa County, Kenya

The study focused on supervision practices on maritime accidents and incidents in territorial waters, Mombasa County, Kenya. The study adopted a descriptive survey design. The objective of the study was to examine the influence of supervision practices on maritime accidents and incidents in territorial waters, Mombasa County, Kenya. The study population was 194 employees of Kenyan Ferry Services (KFS) who included 4 top management officers, 15 middle management and 175 supervisory officers. This study used stratified sampling to identify a sample size of 78 employees which represent 40% of the population. Primary data were collected through a questionnaire. Frequencies, descriptive and inferential statistics were derived to present the data. Demographic information was presented through charts; descriptive statistics presented using tables and bar graphs while inferential statistics, correlation analysis and regression were presented using tables. Analysis was done by Statistical Package for Social Sciences tool. A multiple linear regression model was used to test the significance. Findings revealed that R2 was 0.783, β=0.531, t=8.970, p=0.000<0.05). Study hypotheses concluded that supervisory practices had a statistically significant influence on maritime incidents and accidents in territorial waters in Kenya. Study suggests solutions to curb maritime accidents and incidents in the Coast region. The study may be of importance to the government by using the recommendations to enact policies aimed at further minimizing accidents in Kenyan territorial and internal waters. The study findings may also benefit researchers who may wish to develop the study further through subsequent researches and also the academicians wishing to enrich their knowledge in the concept of supervision practices in curbing maritime accidents and incidents.
