Co-warm B2

In this 21st century is where are the technologies are in advance technological development especially in electrics and electronics. Most of the vending machine can cool and warm the drinks separately. In personal used, the consumers need to buy two different products in cooling and warming the beverages. Practically, this contributes to the high-cost lifestyle and not user-friendly. This is more troubling if there are going for a travel or doing outdoor activities. Based on the current practical and applied technology in electronic device now, the power source of this proposed product uses the USB connection as its main source. Therefore, the target of this project to deliver the portable electronic device can be achieved

Spider Grass Cutter

The regular lawn mower requires manual handling to run and it also uses fuel as the power source in the cutter component. There are a few disadvantages of the regular grass cutter. First, the operation cost of a regular grass cutter increases as the fuel price increases. Second, it is heavy and thus requires a lot of energy to push around. Third, it produces a lot of noise that will disturb the neighbours and surrounding areas. Considering the facts, a project to redesign the handling of a regular grass cutter is proposed by focus on developing the light, easy to carry and easy to store machine system. This proposed system will help the housewives especially to use the mower itself and with little assistance

The implementation of biological tunnel routing protocol (BIOTROP) in tunnel wireless sensor network (TWSN)

A sensor network is composed of a large number of sensor nodes that has expanded tremendously. The sensor nodes can be deployed in any possible applications such as environmental monitoring, industrial sensing and diagnostic, infrastructure protection, battlefield awareness and context-aware computing. In Wireless Underground Sensor Network, the sensor nodes can deploy in two conditions whether buried completely in soil or located in underground confined area like Tunnel Wireless Sensor Network. Due to difference in the implementation of experimental site, the development of a reliable communication can be an important consideration for this project. Therefore, the best routing protocol for tunnel environment named as Biological Tunnel Routing Protocol (BIOTROP) using TelosB sensor nodes is proposed. There are six sensor nodes which were deployed really in a tunnel model at a predetermined distance. The developing process of routing protocol will not neglect the basic limitation of sensor nodes like scalability of network and power transmission. This project implements the forwarding progress that is based on Packet Reception Rate (PRR), Link Quality Indicator and remaining power battery. In minimising the clarification process of network’s path, the BIOTROP upgrade the capability of routing protocol in tunnel environment. Three challenging conditions were setup in experimental process such as low power transmission, all nodes appear as source node concurrently and faster transmission rate. The results have shown more than 70 percent of the transmitted data packets were successfully delivered at the base station. It is also can be implemented practically in tunnel when PRR increases more than 20 percent compared to in a free space condition

Optimal tuning of a wind plant energy production based on improved grey wolf optimizer

The tuning of optimal controller parameters in wind plant is crucial in order to minimize the effect of wake interaction between turbines. The purpose of this paper is to develop an improved grey wolf optimizer (I-GWO) in order to tune the controller parameters of the turbines so that the total energy production of a wind plant is increased. The updating mechanism of original GWO is modified to improve the efficiency of exploration and exploitation phase while avoiding trapping in local minima solution. A row of ten turbines is considered to evaluate the effectiveness of the I-GWO by maximizing the total energy production. The proposed approach is compared with original GWO and previously published modified GWO. Finally, I-GWO produces the highest total energy production as compared to other methods, as shown in statistical performance analysis
