Lead-rich solid industrial wastes were vitrified by the addition of glass formers in various concentrations, to produce non-toxic vitreous stabilized products that can be freely disposed or used as construction materials. Toxicity of both the as-received industrial solid waste and the stabilized products was determined using standard leaching test procedures. The chemically stable vitreous prod...
There is currently no standard method for comparing autonomous capabilities between systems. We propose a test method for evaluating an automated mobile system’s ability to detect and avoid obstacles, specifically those in an industrial environment. To this end, a taxonomy is being generated to determine the relevant physical characteristics of obstacles so that they can be accurately represent...
PID controllers are widely used in industrial plants because the structure of PID controller is very simple and its control principle is very clear [1]. It is practical and very easy to be implemented. Industrial processes are subjected to variation in parameters, which when significant makes the system unstable. So the control engineers are on look for automatic tuning procedures. In this pape...
Several published case studies demonstrate that ergonomics considerations might lead to change the workstations layout and task time values. Traditional procedures take into account only task time analysis and precedence relations, while human postures evaluation is often not integrated in these techniques. Up to now many industrial fields require a systematic approach to allow assembly system ...
The United Arab Emirates (UAE) has experienced tremendous economic and industrial growth in the petroleum, airline, maritime and construction sectors, especially since the discovery of oil reserves. Mass recruitment of low skilled or unskilled laborers from less-developed countries has been utilized to satisfy the manpower demands of these fast paced industrial developments. Such workforce recr...
This paper proposes that industrial waste be regarded, in a business economic sense, as having the same basic status as regular products. A basic mathematical expression for assigning industrial costs to waste is presented. The expression can be employed in conjunction with cost-benefit analysis for estimating the “true” internal costs of industrial waste. In two case studies presented, industr...
The proposed work deals with optimal tuning of a Proportional-Integral-Derivative (PID) controller for speed control of a DC shunt motor. PID controllers are widely used in industrial plants because of their simplicity and robustness. Industrial processes are subjected to variation in parameters and parameter perturbations, which when significant makes the system unstable. So the control engine...
Sophisticated engineering environments for modern business solutions need to combine several specialized techniques in order to meet the growing industrial requirements. Integrated and extensible technology platforms appear to be suitable for this, which however become complex and hence are difficult to use. This paper presents a tool-supported methodology framework for supporting engineers in ...
The data set presented is related to the tensile behavior of cenosphere reinforced high density polyethylene syntactic foam composites "Processing of cenosphere/HDPE syntactic foams using an industrial scale polymer injection molding machine" (Bharath et al., 2016) [1]. The focus of the work is on determining the feasibility of using an industrial scale polymer injection molding (PIM) machine f...
Over the past years, a vast number of datasets have been published based on Semantic Web standards, which provides an opportunity for creating novel industrial applications. However, industrial requirements on data quality are high while the time to market as well as the required costs for data preparation have to be kept low. Unfortunately, many Linked Data sources are error-prone which preven...
