A dispensing system is used in a materials-mixing plant to provide accurate blend ratios in producing the desired end-use product. The AIS-based (Artificial Immune Systems) fine tuning of dispensing parameters is proposed by optimizing the components of dispensing time and stopping time delay to obtain constant and accurate reading from the precision balance scale. Based on the new dispensing sequence,...
In conventional direct torque controlled (DTC) induction motor drive, there is usually undesired torque and flux ripple. In this paper close loop stator flux estimation of DTC with space vector modulation under heavy load at low speed was proposed. First, brief description of stator currents in direct–quadrature reference frame with voltage model. Second, close loop stator flux feedback used through...
In this paper, a crossover factor, fTIG is introduced to the Finite Persisting Sphere Genetic Algorithm (FPSGA). The factor provides a variable range of the loop in the process of Finite Persisting Sphere. By the existing of the variable range, the risk to have too large number of loop or too small number of loop in the FPSGA can be reduced. Too large number of loop will risk of repeating using the...
Electricity consumer dishonesty is a problem faced by all power utilities. Finding efficient measurements for detecting fraudulent electricity consumption has been an active research area in recent years. This paper presents a new approach towards Non-Technical Loss (NTL) analysis for electric utilities using a novel intelligence-based technique, Support Vector Machine (SVM). The main motivation of...
Efficient methods for detecting electricity fraud has been an active research area in recent years. This paper presents a hybrid approach towards non-technical loss (NTL) analysis for electric utilities using genetic algorithm (GA) and support vector machine (SVM).

One of the dominant factors of cable termination fault in medium voltage circuit breaker compartment is due to excessive heating phenomenon. The excessive high temperature area will lead to degradation of the cable insulation. This eventually will lead to insulation failure and hence cable breakdown. The insulation failure may subsequently and causes fire in the cable compartment. A series of experiments...
The influence of the oxide aperture radius on the characteristics of a long-wavelength vertical-cavity surface-emitting laser (VCSEL) lasing at 1550nm is presented in this paper. While previous works in the literature mostly investigate the scaling effects of short-wavelength VCSELs. The importance of studying the effects of long-wavelength operation should not be underestimated, as it could be used...
In this paper, analysis of long wavelength and short wavelength VCSELs are presented. From the simulation results, power output and turn on delay (TOD) are investigated with the variation of Dext (distance between laser facet and fibre). In addition, different Rox (oxide aperture radius) were tested to investigate the effect of the Rox on the modulation transfer function. In the simulation, the comparison...
Even though free space optic (FSO) has the capacity to go beyond the limit of fiber optics but unfortunately FSO suffers a few limitations caused by its transmission medium, the atmosphere. Thus, detail research is needed to study the characteristic of free space optic so as to improve the system subsequently. Simulation using measured parameters is important to gain certain understanding and some...
In wideband code division multiple access (WCDMA) mobile network, total transmission power of node B depends on diverse factors such as accommodation of new service request, termination of active user equipment (UE) and movement of UE. This makes power prediction a complicated task. In this paper, support vector regression (SVR) has been implemented successfully to forecast next interval power consumption...
