Translating theory into practice at the university level is easier said than done. Students often tend to experience difficulty in the application of knowledge learnt, as they seem to be accustomed to learning theory by rote and simply repeating it for the purpose of assessments. A somewhat different approach has been taken by the Design and Manufacturing Engineering (DME) Unit at the University of Trinidad and Tobago. In its BASc and MSc offerings, the DME Unit has made the application of knowledge learnt in the various courses offered a key feature of its programmes. The focus of this paper will be on the MSc programmes offered by the Unit. The DME Unit currently offers two Masters programmes, one which focuses on management (Innovation, Manufacturing Management and Entrepreneurship – IMME) and another which focuses on design (Innovative Design and Entrepreneurship – IDE). These programmes are designed with a view to achieving several outcomes, including fostering the entrepreneurial spirit of students with the intention that they will start businesses at the end of their course of study, thereby commercialising any product or service they develop during the programme; developing their management capabilities, which prepares them for higher level positions and responsibilities at their places of work; immersing students into real-time, problem-based scenarios at companies over the period of a semester to allow them to act as consultants in a work environment different to their own; and nurturing their engineering design capabilities for new product development, with the intention that any such design produced will eventually be commercialised. In light of these outcomes, both programmes share common features in the courses that are covered. Such courses focus on management, entrepreneurship, business development and industry immersion. This paper will highlight the successes of this approach in both programmes.

Earthquake is a devastating natural hazard which has a capability to wipe out thousands of lives and cause economic loss to the geographical location. Seismic stations continuously gather data without the necessity of the occurrence of an event. The gathered data is processed by the model to forecast the occurrence of earthquakes. This paper presents a model to forecast earthquakes using Parallel processing. Machine Learning is rapidly taking over a variety of aspects in our daily lives. Even though Machine Learning methods can be used for analyzing data, in the scenario of event forecasts like earthquakes, performance of Machine Learning is limited as the data grows day by day. Using ML alone is not a perfect solution for the model. To increase the model performance and accuracy, a new ML model is designed using parallel processing. The drawbacks of ML using central processing unit (CPU) can be overcome byGraphic Processing unit (GPU) implementation, since the parallelism is naturally provided using framework for developing GPU utilizing computational algorithms, known as the Compute Unified Device Architecture (CUDA). The implementation of hybrid state vector machine (H-SVM) algorithm using parallel processing through CUDA is used to forecast earthquakes. Our experiments show that the GPU based implementation achieved typical speedup values in the range of 3-70 times compared to conventional central processing unit (CPU). Results of different experiments are discussed along with their consequences.

In order to improve the Equipment Reliability and Availability in the Industries in the Caribbean this paper discusses the use of existing Maintenance and Reliability theories in the areas of condition monitoring techniques, root cause analyses, quality systems, Computerized Maintenance Management Systems (CMMS), Planning and Scheduling, Reliability Centered Maintenance (RCM), Total Productive Maintenance (TPM), the Ishikawa Diagram in addition to introducing a guide to facilitate their application. It describes the management accounting system, driven by leading and lagging Key Performance Indicators (KPI’s), which ensure sustainability in the implementation of the improvement recommendations in the maintenance and reliability systems in these industries. Emphasis is placed on the need for Engineers and other professionals in the industry to play key roles in deciding when and for how long equipment shall be run and subsequently taken out of service. This can only be achieved by “placing their shoulders to the wheel” and working with passion towards their focused goals. They need to celebrate and learn from their successes and be innovative and critical thinkers to efficiently and effectively surmount any barriers in their way.

The unsteady magnetohydrodynamic Poiseuille flow of a viscous, incompressible, hydromagnetic fluid through a porous channel, bounded by two horizontal plates under an oscillating pressure gradient, is studied. The Brinkman's equation is used to model the flow and the Galerkin Finite Element Method is used to solve the governing equations. The values of Hartmann number (Ha), frequency of oscillation (ω), suction/injection parameter (S), the permeability parameter (α), time (t) and the amplitude of the pressure gradient (A) are discussed. The results obtained are in good agreement with the existing literature.

In a developing country like India with scarce hydrocarbon reserves and also due to variable nature of Renewables in terms of potential, penetration and technology, Coal must be relied upon as a source of energy in near future also, to meet the ever-growing demand for an instant form of energy i.e. Electricity. An alternative to not so clean source Coal appears to be Nuclear Power and this option can supplement and supplant our energy needs despite several concerns from various sources post-Fukushima Nuclear accident. This paper carries out a detailed LCA study of Nuclear based Electric Power Generation System with a wider scope that encompasses the waste disposal and spent fuel reprocessing phases, is modelled and run on SimaPro 9.0.0.48 LCA software with ECOINVENT 3.0 as database. This study also covers the all-important Inventory Analysis for the inputs used, raw material extracted and residuals consequently released to the environment. The results are expressed in terms of pre-defined energy metrics such as ERR and EPBT. Further, the study covers the environmental impact assessment category such as GWP and finally the results are presented with a kWh of electricity produced by this option as a functional unit. These investigations help energy planners and policymakers to compare various power generating options and justify the alternatives to meet future demand for electricity in a cleaner and more sustainable manner by keeping the spirit of Paris Climate Agreement in mind.

This paper describes the simulated environment that was prepared for validation of Cognitive Function Synthesis, or CFS, Autonomy. The environment was developed with the V-REP simulator and assembled around the ‘Eric Rohmer’ Pioneer robot. The simulated robot was configured to act as a Behaviour-Based Robot that is constrained to move about the test area, as defined by a state diagram, and based on pre-configured reflexes, provided by the Braitenberg algorithm. Vision sensors, i.e. simulated cameras, were found to be better suited to configure these behaviours than light sensor cues. Initial results suggest that the simulated environment may be used for CFS autonomy validation. This research marks the first simulated environment produced for investigating CFS Autonomy and consequently needs to be further validated.

: Water management at alumina refineries and associated power plants is a major concern, especially if water resources are scarce and liquid discharges are not permitted. This paper describes the case of one such plant in Jamaica recovering 350 m 3 /h of digester regenerative condensate. The steam and power for the alumina refinery is supplied by a cogeneration facility, which has to use a mix of well water and return condensate from the steam users in the alumina production process. The refinery produces alumina from Jamaican bauxite ore, using the Bayer process. This process includes the digestion of bauxite with sodium hydroxide at 135 deg.C, hence the requirement for both steam and power. In the course of this extraction, large quantities (350 m 3 /h) of digester and evaporator condensate are produced. In view of the limited liquid discharges permitted from the site, this condensate was stored on site in large ponds, and reused in the process. Pressured from three sides, with a limitation on raw water abstraction from the wells by the Water Resource Authority, a requirement for minimized liquid discharge of wastewater, and high cost of energy there was a need to utilize the regenerative condensate from the digesters and the evaporators as boiler feedwater. Studies carried out by international water treatment companies had concluded that Total Organic Carbon (TOC) would not allow condensate re-use as boiler feedwater, with an attached US$10 million cost for the removal of TOC. Extensive laboratory work and thermodynamic analysis were carried out and the condensate are used as boiler feedwater, without treatment. The avoided cost was US$10 million and energy savings of US$3 million realized.

Advances in reinforcement technology has facilitated the transition from traditional steel rebar to non-metallic rebar in reinforced concretes. Consequently, chloride content can be dramatically increased without worry for the deterioration of the encased reinforcement in reinforced concretes that utilizes composite rebar and polymeric/ceramic fibres. The production of one tonne of concrete releases 900 kg of CO2 emissions. Reductions in CO2 emissions from concrete production can be achieved through the production of ‘greener’ cements, and utilization of localized aggregate sources. Construction of structures along the coastline provides a unique opportunity for the utilization of beach-sand and brackish water that together can improve the sustainability prospects for construction in these environments. The incorporation into concrete of beach-sand that has been previously excavated is a simple means of reducing reliance on traditional sources of fine aggregate for concrete production. Additionally, the use of brackish water from a nearby estuary has the added benefit of reducing the requirement for potable water. Compressive strength tests were conducted on twenty-two (22) groups of specimens at 7-days, 28-days and 42-days. Water-to-cement ratios (w:c) of 0.37, 0.39, 0.43 and 0.45 were employed. Analysis showed that at 0.37 w:c, batches that utilized beach-sand and brackish water, beach-sand and potable water, concreting-sand and brackish water were comparable to those produced with concreting-sand and potable water at about 40MPa.

This paper analyses results from experiments performed using a previously-described, simulated environment that was developed for validation of Cognitive Function Synthesis, or CFS, Autonomy. Navigation performance of the Pioneer robot platform used the following metrics: Average Cycle Time per simulation run; Average Wall Contact per cycle; and Average Shock Treatment Activation per simulation run. Two ultrasound, or US, configurations were used while the robot navigated in either the ‘preconfigured-reflexes only’ mode or the ‘Braitenberg Obstacle Avoidance’ mode. Results from the “16 sensor” US configuration was generally found to be significantly different from that of the “8 sensor” configuration, independently of obstacle avoidance considerations. Robot performance, when subject to the Braitenberg Obstacle Avoidance algorithm, was also found to be significantly different from ‘preconfigured-reflexes only’ performance, regardless of US configuration. The difference in Shock Treatment and the Average Wall Contact, observed between the “16 sensor” US setting and the “8 sensor” configuration for the ‘Braitenberg Obstacle Avoidance’, are likely to be due to the coefficient values adopted for the rear US sensors together with robot position at experiment start. The use of this environment to enable statistical analysis of results, to determine significant difference in obstacle avoidance performance, validates its usefulness as a tool for CFS Autonomy validation.
