Implementation and comparison in using state pattern on main character movement (case study : pocong jump video game version 1.0)

Abstract: Game development success is often hard to achieve due to various problems such as performance issues, malfunctioning features, and poorly organized program structure. The problems that arise can be prevented by using the design pattern as a game programming architecture from the beginning of development. By implementing a design pattern, the process of developing video games can be made easier and simplified. The development team can focus its efforts on producing better quality video games. In this study, design patterns that would be used are state pattern and finite state machine. The state pattern is implemented by encapsulating the character's behavior in a class called state. Finite state machine will then facilitate the transition of states caused by user/player input or variable value changes. State pattern and finite state machine is tested with test case and game performance is tested with software metric. The result obtained from this study are state pattern and finite state machine have a valid component structure and could improve performance efficiency in video games.

Simulation and analysis of stand-alone photovoltaic system with boost converter using MATLAB/Simulink

Abstract: Use of renewable energy and in particular solar energy has brought significant attention over the past decades Photovoltaic (PV) power generation projects are implemented in very large number in many countries Many research works are carried out to analyze and validate the performance of PV modules Implementation of experimental set up for PV based power system with DC-DC converter to validate the performance of the system is not always possible due to practical constraints Software based simulation model helps to analyze the performance of PV and a common circuit based model which could be used for validating any commercial PV module will be more helpful Simulation of mathematical model for Photovoltaic (PV) module and DC-DC boost converter is presented in this paper The model presented in this paper can be used as a generalized PV module to analyze the performance of any commercially available PV modules I-V characteristics and P-V characteristics of PV module under different temperature and irradiation level can be obtained using the model The design of DC-DC boost converter is also discussed in detail Simulation of DC-DC converter is performed and the results are obtained from constant DC supply fed converter and PV fed converter

Image processing based forest fire detection using YCbCr colour model

Abstract: In this paper image processing based forest fire detection using YCbCr colour model is proposed. The proposed method adopts rule based colour model due to its less complexity and effectiveness. YCbCr colour space effectively separates luminance from chrominance compared to other colour spaces like RGB and rgb(normalized RGB). The proposed method not only separates fire flame pixels but also separates high temperature fire centre pixels by taking in to account of statistical parameters of fire image in YCbCr colour space like mean and standard deviation. In this method four rules are formed to separate the true fire region. Two rules are used for segmenting the fire region and other two rules are used for segmenting the high temperature fire centre region. The results obtained are compared with the other methods in the literature and shows higher true fire detection rate and less false detection rate. The proposed method can be used for real time forest fire detection with moving camera.

Voltage flicker mitigation by FACTS devices

Abstract: This paper deals with the Voltage flicker in power systems. Voltage flicker is one of the disturbances in power systems. This voltage flicker occurs due to non linear loads. A three phase four wire inverter system is consider to compensate the voltage flicker. The three phase four wire inverter can perform multi functions such as : 1) it transfers the power to the main line from DC link, and 2) it acts as shunt Active Power Filter to mitigate reactive power demand, unbalance current, harmonic content in load current, and neutral current at load. Inverter can perform these functions individually or simultaneously. In this paper voltage flicker mitigation can be done by using FCTCR (Fixed Capacitor Thyristor controlled Reactor) and 3-φ, 4-wire inverter (STATCOM) of eight pulses. From the above two compensating devices STATCOM results show effective mitigation of voltage flicker. Simulation results are shown in MATLAB software.

Assessment of flicker owing to turbulence in a wind turbine placed on a hill using wind tunnel

Abstract: This paper bequeaths particulars of impact of turbulence on the flicker produced in the wind turbine which is sited on that surface. This is achieved in a laboratory wind tunnel with small models of hills with different slopes and wind turbine. Different shapes of models of hills placed in a laboratory wind tunnel. Wind turbines are tested for those conditions. The paper provides an empirical model to find flicker in terms of hill topography. The exquisiteness of the model is that, it is expedient to sundry types hills on which the turbine is sited. Validation of model is carried out with comparative graphs revealed with readings recorded on a turbine in tunnel.

QoS based multipath routing for intrusion detection of sinkhole attack in wireless sensor networks

Abstract: Wireless Sensor networks (WSN) is basically comprised of sensors that are spatially distributed with self-ruling capability, which monitors physical or environmental conditions such as, pressure, temperature, motion, sound and so on. Sensors also passes all the related information throughout the network. As the number of nodes and size of the network increases, there will be rapid increase in internet traffic. In WSN, security is the major issue and needs to a system that can provide security. Intrusion detection system is the system which plays a vital role in security of a system. One of the major challenges of WSN is to provide consistent Quality of Service (QoS) such as reliability, congestion control, energy efficiency and end-to-end delay, by applying secured routing protocols along with detection of an intruder so that QoS of WSN does not get affected. In our research work, we have discussed different routing protocols that are QoS based, to improve overall performance of the network.
