The implementation of Movement Control Order (MCO) to curb the spread covid-19 in Malaysia has resulted an increased financial burden on people especially those from low-income group. Therefore, taking advantage promising renewable energy as free source electricity could subsequently reduce borne by this Hence, paper conducts analysis using MATLAB/Simulink software, assess viability small-scale...

This project presents decentralized control scheme for Load-Frequency Control in Multi-area power System. In this era renewable energy is most promising solution to man’s ever increasing energy needs. But the power production by these resources cannot be controlled unlike in thermal plants. A number of optimal control techniques are adopted to implement a reliable stabilising controller. It is ...

Voltage unbalance negatively affects both distribution network operators (DNOs) and customers by introducing overheating, accelerated thermal ageing of equipments, reduced efficiency and therefore additional financial cost. Once a new source of unbalance appears in the network, the overall degree of unbalance of the network will be increased, contributing to the system losses additionally. The ...

planning robot trajectory is a complex task that plays a significant role in design and application of robots in task space. the problem is formulated as a trajectory optimization problem which is fundamentally a constrained nonlinear optimization problem. open-loop optimal control method is proposed as an approach for trajectory optimization of cable parallel manipulator for a given two-end-po...

A manageable, relatively inexpensive model was constructed to predict the loss of nitrogen and phosphorus from a complex catchment to its drainage system. The model used an export coefficient approach, calculating the total nitrogen (N) and total phosphorus (P) load delivered annually to a water body as the sum of the individual loads exported from each nutrient source in its catchment. The exp...

Trapezoidal sheeting of thin-walled steel is applied frequently for roofing and cladding. As such, it is loaded by a concentrated load (at the support) and a bending moment. A recently developed model to predict the sheeting's failure behaviour leaves the question open whether mode jumping (the phenomenon where a plate dynamically changes its buckling mode during an increasing load) should be t...

Considering the fact that rocks fail faster under tensile stress, rock tensile strength is of greatimportance in applications such as blasting, rock fragmentation, slope stability, hydraulic fracturing,caprock integrity, and geothermal energy extraction. There are two direct and indirect methods tomeasure tensile strength. Since direct methods always encompass difficulties in test setup, indire...
