This paper applies genetic algorithms to the problem of induction motor parameter determination. Generally available manufacturers published data like starting torque, breakdown torque, full load torque, full load power factor etc, are used to determine the motor parameters for subsequent use in studying machine transients. Results from several versions of the genetic algorithm are presented as...

Due to growth of mechanisation and automation, today’s industrial systems are becoming more complex. A small breakdown of any non-redundant machine component affects the operation of the entire system. To increase the availability and reliability, automated health monitoring and self-diagnostic capability (SDC) becoming essential to many industrial machineries like pumps, motors, etc. Condition...

Due to expensive, highly complex and time-consuming processes, semiconductor-manufacturing systems have been given a special attention. In our previous work (Tang et al., 2003), a heuristic algorithm to design the reconfigurable automated production system was proposed. However, machine breakdown and planned/unplanned maintenance were not considered. This paper extends that work and addresses t...

Hybrid algorithm based on Particle Swarm Optimization (PSO) and Simulated annealing (SA) is proposed, to solve Flexible Job Shop Scheduling with five objectives to be minimized simultaneously: makespan, maximal machine workload, total workload, machine idle time & total tardiness. Rescheduling strategy used to shuffle workload once the machine breakdown takes place in proposed algorithm. The hy...

This deliverable reports on the results of the WebSand work package on Secure Web Interaction. It provides a wording definition and technical specification of the term and builds the basis for the development of the server-side framework that achieves Secure Web Interaction.

In order to improve insight into the impact of mechanical stress on the winding insulation of rotating machines, for the first time simultaneous electrical and mechanical stresses were applied at a frequency as high as 100 Hz. Improving tests described in literature, vibration frequency and bending stress were chosen closer to reality such as 100 Hz and 7 N/mm2, respectively. The goal was to fi...

Excessive downtime remains a problem for many organisations, particularly those using complex capital intensive manufacturing processes. To counter this, many use computerised management systems to support various aspects of their maintenance activities including breakdown diagnosis. This paper describes research that has been undertaken to investigate the effectiveness of maintenance informati...

Data load balancing is one of the key problems of big data technology. As a big data application, Hadoop has had many successful applications. HDFS is Hadoop Distributed File System and has the load balancing procedure which can balance the storage load on each machine. However, this method cannot balance the overload rack preferentially, and so it is likely to cause the breakdown of overload m...
