As risk and uncertainty arise, there is a bright spot of hope for mitigating Political and Credit Risks: Public Private Partnerships. As evidenced through multiple successful collaborations, the public and private sectors are able to align the complementarity of their competitive advantages to promote trade and economic growth.
The paper will discuss the general topic of predictive control techniques for industrial applications, in particular the implementation of Kalman Filter State Estimators in such control schemes. The paper presents the investigation of predictive control methodologies for the control of a model powder blending process. This investigation was carried out in an effort to improve the performance of a...
Vacuum technology is a very widespread area. Nowadays, a broad variety of applications can be found to be using vacuum and vacuum related monitoring. Vacuum profile for different applications can be different, but whatever that may be, monitoring it is an essential part of any such application. Thus, this paper describes the development of one such vacuum profile monitoring system that can be re-purposed...
Research in Machine Learning has increased dramatically over the past couple of decades, with applications greatly benefitting industry. These applications vary widely in the fields of space exploration technologies, transportation, robotics, agriculture, animal husbandry, medicine and finance. However, the agricultural and animal husbandry related applications are relatively few when compared to...
Increased globalisation and competition are drivers for process analytical technologies (PAT) that enable seamless process control, greater flexibility and cost efficiency in the process industries. The paper will discuss process modelling and control for industrial applications with an emphasis on solutions enabling the real-time data analytics of sensor measurements that PAT demands. This research...
The emergence of trends such as the Industrial Internet of Things (IIOT), Industry 4.0 and Process analytical technology has heightened the demand for real-time, in-line and affordable sensors. The mass flow rate of bulk solids is a parameter that is invaluable to process understanding in many applications. Despite this the availability of affordable sensors is limited. This paper will investigate...
The mass flow measurement of a bulk solid is one of the most common parameters monitored in the materials processing industries and enjoys a wide range of sensory options to accurately quantify the mass flow of a given material. The emergence of Process analytical technology has heightened the demand for such information to be provided to process analysers, in real time and low cost in order to allow...
Increased globalisation and competition are drivers for process analytical technologies (PAT) that enable seamless process control, greater flexibility and cost efficiency in the process industries. This research is carried out in collaboration with a project which aims to introduce an integrated process control approach, embedding novel sensors for monitoring in real time the critical control parameters...
This paper is the result of a literature review focusing on the application of process analytical technology (PAT) for the pharmaceutical industry in conjunction with the quality by design (QBD) framework. PAT and the QBD framework put forward by the FDA, offer a holistic approach to manufacturing pharmaceuticals, emphasising the understanding of process variables on the end products characteristics...
Academic and industrial research in Internet of Things (IoT) has increased over the past several years. The Internet of Things aims to connect physical objects (Things) to the Internet using low power network connectivity that is embedded with sensors. IoT is becoming all-encompassing with “Smart” Cities, Homes, Grid, Transportation, Agriculture & Industry 4.0 just some of the application areas...
The aim of this study is to research the requirements for the development of a bench test system, in order to address the control and measurement of a PTC heater in a modern automotive heating, ventilating, and air conditioning (HVAC) system. Two avenues of investigation were explored; how testing of Positive Temperature Coefficient (PTC) heaters is carried out with standard wind tunnel technology...
LED (Light Emitting Diode) lighting systems (commonly known as LED luminaires) are beginning to experience widespread use in many lighting applications and are slowly becoming accepted as the norm for domestic, commercial and industrial lighting systems. However the reliability of LED luminaries is still unclear due to the long reliability test times. These long test times have become a barrier to...
Increased globalisation and competition are drivers for process analytical technologies (PAT) that enable seamless process control, greater flexibility and cost efficiency in the process industries. This research aims to introduce an integrated process control approach, embedding novel sensors for monitoring in real time the critical control parameters of key processes in the minerals, ceramics, non-ferrous...
An innovative process is proposed for the calibration of thermometric devices, combining materials which change state at primary temperature calibration points defined in international standards, and electrical impedance measurement techniques. The process will use pure samples of such materials and a measurement apparatus which enables the automated matching of the elimination of measurement bias...
This paper investigates the potential for using the freezing-points of high-purity metals for direct temperature calibration, on site and at low cost. These freezing-points are primary calibration points in the International Temperature Scale (ITS-90) [1]. It has been found that small amounts of high-purity metals can be obtained in the marketplace cheaply. Experiments were carried out by driving...
The human auditory system perceives sound in a much different manner than sound is measured by modern audio sensing systems. The most commonly referenced aspects of pure-tone auditory perception are loudness and pitch which relate to the objective measures of frequency and sound pressure levels. Current, accepted models for the perception of sound operate at a discrete level, modeling the perception...
Renewable energy is an essential area of development in many countries and has attracted a great deal of investment. The use of micro-generator wind turbines is encouraged for individuals to set up their own power generator which will create a positive environmental impact. Power generated from a micro-generator can also be exported back to the national grid with many micro-generation schemes available...
The present study investigated the development of a low-cost sensor for the determination of milk fat content in homogenised milk using short-wave radiation. Following literature review, potentially suitable wavelengths were selected for quantitative analysis. A circuit comprising of LEDs, photodiodes and differential amplifiers was developed and a sample chamber constructed to house the electronic...
Communication systems are undergoing constant and rapid innovation, both at the design stage and in the field. This in turn has led to an increasing need for fast, efficient, portable and economic methods for the testing of these systems. For voice carrying communication systems the quality of the transmitted voice that the system produces is a large factor in the systems overall performance rating...
