This research is focused on the use of process control in wastewater treatment systems, with a specific emphasis on aeration control, recirculation stream control, and chemical addition control. The paper covered mathematical background of process control, including the use of differential equations, linear and nonlinear systems, feedback control, and PID control. It also provided information on how to adjust process control by tuning the K parameters, how to optimize the performance of aeration, recirculation stream and chemical addition control by using advanced control strategies such as model predictive control, adaptive control, or optimal control.

The research paper is dedicated to investigating legal and professional issues in Uganda's software engineering industry. The paper reflects on academic perspectives on the issue and the lack of relevant academic publications that overview the causality behind the software engineering problems in Uganda. The limited amount of literature on the topic that does exist presents a roadmap to solve the challenges potentially. The overview of the software engineering industry of Uganda is presented. Professional issues that are discussed in the paper include not conducting Requirements Engineering Process Improvement, low quality of practical software engineering education in the universities, lack of adherence to international standards, poor career development, and engineers focusing on seeking foreign jobs. Legal issues include a lack of implementation of the relevant law, multi-sector corruption, and the challenges related to the ease of doing business. The research concludes that the multi-dimensional approach that involves state, academia, and companies has to be used to solve the underlying issues.
