Quadrotor is a kind of multi-variable, strong coupling and nonlinear characteristics of complex systems. In order to improve the stability of four-rotor aircraft flight performance and control, a sliding mode controller is designed primarily for using Newton-Euler equations to build and simulate the mathematical model of quadrotor for location tracking in this paper. Since approximation error and uncertainties are existed in the considered system, the gain parameter values must be preset and not be easy to find. Therefore, the cerebellar model is chosen to overcome the previously encountered problems. Control law is derived through Lyapunov stability analysis to ensure the stability of the system. In view of the simulation results, it is obvious that the proposed controller has a good track performance.

This paper proposes evaluation and implementation for media player system by hand gestures using Kinect sensor. The hardware consists of the Kinect for Windows with infra and color camera sensors to capture the depth and plane images, respectively, while the control program is written by VC#. When users execute the control program, the functions of the Media player system can be easily controlled by some simple hand gesture motions through the Kinect detection sensors as practically to manipulate the push-bottoms of the media player system by mouse or keyboard on the screen. By capturing the hand waving speeds, the data to calculate the average hand movement speed are used to setup the speed threshold as the default in our system. In experiments, we analyze the hands' movement speeds sensing by different ages of users to obtain the hand moving average speeds and correct the threshold speed of the posture recognition on Kinect for the media player system in Windows 7 operation system.

To elevate the imperativeness and reinforce the fitness of elders, assisting a home care system can be an admittance that provides comprehensive nursing and monitoring them in the regular interim. In order to provide an interactive service management platform to the elders a smart environment of numerous sensors are clubbed together to establish an intuitive platform that can control the home appliances and gadgets within the living space of elders. The proposed system used voice and gesture to control the home appliances like turning on/off the light, closing/opening of curtains, TV, and fan or AC within the living spaces. The system also supports the real-time activity and monitor the healthcare system for the elderly citizens like heart rate and body temperature. In the case of emergency, for instance, anomalous behaviors like heart stroke occur, the proposed system set-up triggers an alarm and the emergency bulb will be on to alert to their kin. This smart environment can set the temperature and help control the living parameters of light based on the users' comfort and their health conditions. The whole design is to provide modest support systems for the elder to live healthily and safety in the independent living of elders.

In this paper, an adaptive proportional integral derivative (PID) based on radial basic function neural networks (APID-RBFNs) is proposed for tracking control of a 2 degree of freedom (DOF) parallel manipulator. For developing the controller, a dynamic model of this parallel manipulator is developed based on a matrix form equations. APID-RBFNs is designed to overcome external disturbances and complex noises acting on the parallel manipulator system by using adaptive PID sliding surface with RBFNs. By using the Lyapunov method, the stability of the overall system with full state constraints is proved. The simulation results in universal software Matlab/Simulink show that the proposed control strategy has better dynamic performance and robustness than conventional PID tracking control.

The thixoforming process is becoming more and more important in the field of metal-forming. In this process, the most difficult part is heating the sample while keeping the temperature uniform. The pressing speed is one of the main parameters that impacts strongly on product quality. In this paper, the mold for studying the effect of pressing speed was designed and manufactured. The Deform 3D software was applied for observing the relationship between the pressing speed and the force history, stress, and temperature distribution. The results show that a pressing speed of v = 8 mm/s results in the smallest stress. The stress depends on many elements. For example, the pressing speed of v = 6 mm/s makes the heating process happen fast. The billet is cooled faster so the stress increases and even changes the structure unexpectedly. When the pressing speed is too high, the metal on the surface of the billet flows with high speed so it collides with the folding segments causing great resistance thus creating high stress.

Nowadays, in the context of the demand for energy is growing by the day, the fossil energy sources are being depleted and environmental pollution problems caused by the exploitation and use of this energy resources is causing severe consequences for life on Earth, the development of renewable energy has become a strong trend throughout the world. In types of renewable energy sources, solar and wind energy are the two most potential renewable energy sources because they have greater availability in all areas and they should be able to exploit in various sizes and forms. However, a single renewable energy source system can't provide a continuous power because of difference of the weather condition of seasons. So, research and use a hybrid energy system is necessary. To exploit wind energy efficiently, design of the high-performance wind turbine's blade profiles is extremely important. To maintain the performance of the panels at the highest level we need a system of adjustable panels that are always facing the sun. This paper will show the design process of a hybrid energy system with a helical darrieus wind turbine and a sun tracking solar panels system. The purpose of this system is generating an uninterrupted power without damaging the nature, applying easily in areas where people do not have electricity grid and helping households in areas where people have electricity grid reduce the cost of electricity consumption. A hybrid energy system with calculated power 1136 Wh/day is designed.

Absorption phenomenon of NH3 into NH3-H2O solution has analysed theoreticcally. The heat transfer coefficient obtained from the coupled heat and mass transfer mathematic model. This heat transfer coefficient is used to calculate the variation of the simulated value of heat load. The practical decrease of wetted ratio analyses were taken into account when the solution flow from the top to the bottom of the parallel tube bundle. The deviation of theoretical heat load and experimental heat load is about 10%. In addition heat transfer coefficient and mass transfer coefficient of the absorption process are agree well with other studies. A correlation which gives the heat transfer coefficient and mass transfer coefficient as funtions of the initial solution concentration, solution mass flow rate per unit tube length, and cooling water temperature are derived to estimate the absorber heat load and mass absorption flow rate of NH3 vapor into NH3-H2O solution.

In this paper, the service robot named “BlackBot” as receptionist robot is descried, that is a small three-wheeled mobile platform with a differential drive, which was controlled by a mini PC. The BalckBot could sense its surroundings with the aid of various electronic sensors while mechanical actuators were used to move it around. Robot's behavior was determined by the program, which was loaded to the microcontrollers and PC. The experiment results demonstrated the feasibility and advantages of this predictive control on the trajectory tracking of a mobile robot. The service robot is designed to assist humans with reception tasks. The robot will interact closely with a group of humans in their everyday environment. This means that it is essential to create models for natural and intuitive communication between humans and robots.

In this study, the mold operation fluid will be controlled for observing the cooling efficiency of conventional cooling and pulsed cooling. The cooling techniques will be compared under varying mold temperature, coolant temperature, melt temperature, and flow rate. A mold structure was built using stainless steel 420. The cavity plate contains two cavities. Each cavity will be used for one type of part thickness. Results show that by appropriately controlling the fluid in pulsed cooling, the cooling rate can be improved from 0.552 °C/s to 0.755 °C/s and the warpage can be reduced by 20%. Moreover, as compared with conventional cooling, pulsed cooling can reduce warpage by 20% because pulsed cooling can maintain a stable heating/cooling temperature history and offer sufficient cooling to reduce warpage.
