    Computer Integrated Manufacturing Sub-Systems in Technical and Vocational Education and Training: A Bewilderment for Stakeholders in Polytechnics in Zimbabwe
    (Indiana Journal of Humanities and Social Sciences, 2022-03-31) Muzari, T.; Chasokela, D.; Sithole, A.
    The embracing Computer Integrated Manufacturing (CIM) sub-systems are indispensable for sustainable development of entrepreneurship skills of students in Technical and Vocational Education and Training (TVET). There seems to be a dearth of requisite skills in Polytechnic students in Masvingo Province to measure up to the expectations of industry in this technological era. A case study of a polytechnic college was carried out to assess the barriers that militate against students’ acquisition of full training in accredited TVET programmes. The study employed the qualitative approach which focuses on the interpretive paradigm. Five students, five lecturers, four college administrators and three captains of industry were purposively sampled to participate in semi-structured face to face interviews and participant observations. Results revealed that there are resource constrains and physical infrastructure inadequacy as well as mismatch between industry and training institution in the provision of indispensable CIM software packages. The results also showed that not every lecturer is capable of using CIM sub-systems during teaching and learning besides having been staff-developed. The study recommended that TVET lectures be extensively condensed on the acceptance and use of CIM technology so that they become capable of using such technologies during teaching and learning taking cognisance of the 21st Century industry expectations. There is need for the college through both government agencies and non-governmental organisations to initiate and mobilise resources to sufficiently equip TVET colleges with technological devices and indispensable CIM software packages. The training institution is recommended to network for collaboration and partnerships as well starting innovation hubs inform of campus companies which would produce the same services that the industry is providing.

    Fuzzy PI Based Motor Speed Control using DSP TMS320F2812
    (International Journal of Latest Research in Humanities and Social Science (IJLRHSS), 2022) Chasokela, D.
    Alternating Current (AC) induction machine plays an important role in the entire industry and daily life. This is due to their robustness, inexpensive and easy to maintain in a period of time. Vector control is used in large numbers in the speed control of AC induction machine. High dynamic performance high speed precision and wide constant torque range capabilities are the key benefits of vector control. Stability of the system during transient process and a wide range of operation are assured through the application of vector control. The purpose of this thesis is to study the vector control of AC induction machine based on the principles of the AC speed control system, vector control and fuzzy Proportional integral (PI) control, and implementing the digital vector control systems based on the digital signal processor (Digital Signal Processor-DSP TMS320F2812) from Texas Instruments. The mathematical modeling of the AC induction motor and the principles of vector control and fuzzy systems are overviewed first. Fuzzy PI regulator is then proposed to carry out the regulation of the motor speed. The fuzzy PI is an intelligent technique that has evolved in the last decades and it emulates the human way of thinking. Therefore the fuzzy PI does not need the exact mathematical model. In-depth study of fuzzy PI and the normal PI was carried out. Matlab/Simulink software is used to simulate the vector control of the AC induction motor with both fuzzy PI regulator and normal PI regulator for comparative purposes. Simulation results showed that fuzzy PI has a better performance in terms of stability, faster response and robustness, and the fluctuation ripples are also smaller. Experiments had been done on the laboratory platform of AC drive system with the help of AC speed control monitor program designed in Laboratory Virtual Instrument Engineering Workbench (LabVIEW) under variable operating conditions. The experimental waveforms were captured using the LabVIEW monitoring software. In order to carry out real time implementation, Code Composer Studio and SEEDXDS510plus Emulator are adopted to programming and testing with the DSP TMS320F2812. Experiments results show that the fuzzy PI regulator performs better than normal PI regulator, as fuzzy PI regulator indicates better waveforms of torque and speed responses during acceleration and deceleration, especially when the motor is operating on lower speeds.

    Intelligent Condition Monitoring of a Ball Roller Bearing
    (Indiana Journal of Humanities and Social Sciences, 2022-04-30) Chasokela, D.; Muzari, T.; Tshuma, L.S.
    A bearing itself is one of the essential components that allow constrained relative motion between two or more parts, typically motion or linear movement. It is cylindrical in shape and contains small metal balls and has caused various problems in machineries. Common roller bearings use cylinders of slightly greater length than diameter. Roller bearings are therefore the earliest known type of rolling element bearing. Maintenance of rotary machinery is very essential in all walks of different industries and recently has attracted great attention. Methods of detecting and diagnosing the defective rolling element bearing. Numerous methods have been developed based on intelligent condition monitoring and in this case artificial neural networks, fuzzy expert system, condition based reasoning, vibration measurements, temperature measurements, shock pulse method have been applied and measured. Acceleration sensor was applied on a roller bearing with a charge amplifier to measure acoustic emissions. Analogue-Digital converter was used to produce signal pre-processing which lead to feature extraction. Time and frequency domains were used to show signals change over time and analysis of mathematical functions of signals respectively. Artificial Neural Networks and pattern recognition identifies defects. The computer uses mathematical laboratory software (MATLAB) for command plots of inputs and output signals and indicates a normal or a failing bearing..

    Quality Higher Education for Sustainable Development: The Transition towards Achieving Agenda 2030 Global Goals
    (International Journal of Latest Research in Humanities and Social Science (IJLRHSS), 2022-02) Manokore, K.; Tlou, F.; Mkwelie, N.; Phuthi, N.; Shava, G.N.; Mhlanga, E.; Mangena, A.; Sibanda, Z.; Chasokela, D.
    Quality Higher Education and Education for Sustainable Development (ESD) have become part of the discourse and issue in higher education contexts. Every phase or debate of higher education is now being urged to declare its support for ESD. Recently the United Nations (UN) 2030 Agenda proposed that quality education and ESD should play a vital role for the transformation of the world‟ s economy as expressed in the Agenda‟ s goals and sub goals. The UN Incheon Declaration 2015 highlighted the vital role of education that it plays in the universal journey towards sustainable development across the globe and saving our planet. Higher education should play a pivotal role in the transition towards achieving quality in the entire education system. The UN formally adopted the 17 sustainable development goals (SDGs) as an outcome of a major global consultative process. Agenda 2030 advocates for providing the opportunity to progress towards the transition to implement quality education and ESD that fosters the knowledge, skills, values, perspectives and actions that lead towards a more sustainable future. The study examines the implementation of Agenda 2030 Global Goal on quality and sustainability in Zimbabwean higher education. The aim of the study is to increase knowledge of potential strategies to meet the fourth UN Sustainable Development Goal (SDG4), which strives for quality education. Institutions in the study were at different levels of interpretation, understanding and implementation of Agenda 2030 for Sustainable Development Goals. The majority of the participants did not have an all-inclusive knowledge and comprehension of ESD mainstreaming as a holistic approach. That is, an allembracing ESD integration as a curriculum systemic concept that holds both curriculum and institutional change, to contribute to the overall re-orientation of education towards sustainability. The qualitative study provides a detailed description on the challenges of implementing quality and sustainability in higher education.

    Women in Higher Education Leadership and Parenthood: Experiences from a University in Zimbabwe
    (Springer Nature, 2021-02) Shava, G.N.; Chasokela, D.
    In Zimbabwe and most probably the rest of Africa, the occupational and leadership status of women in higher education leadership is still suffering a wide gap as there is unequal representation in leadership positions between men and women. Although women have made substantial gains in higher education learning institutions, they have not achieved parity with men. Women in Zimbabwe higher education are particularly underrepresented at higher levels of leadership and the percentage of female executives decline with increasing organizational rank. Despite the fact that women constitute the majority of workforce in universities in Zimbabwe, they remain poorly represented in high-level leadership positions. Where women have attained high-level leadership positions, they remain disadvantaged, their progress remain impeded due to parenthood responsibilities. Despite the fact that in Zimbabwe today women earn the majority of college and university degrees, they are less likely than men to experience benefits associated with leadership and promotion and they continue to represent a smaller proportion of leadership positions. This study derived from a qualitative case study undertaken at a university in Zimbabwe was conducted to establish challenges faced by women in higher education leadership. The research findings indicated that cultural and social barriers continue to grow and pose a formidable barrier to women in leadership positions. The researchers argue that organizational structures, parenthood and culture make it difficult for women to rise into higher levels in leadership positions.
