the integration of renewable energy sources into an existing grid requires grid-tied inverters. the reliable and accurate dispatch of real and reactive power to the grid is achieved by controlling the inverters. Recent trend is to operate such grid-tied inverters as virtual synchronous generators. this requires time-intensive solution of the complex machine equations to controlthe inverter outputs. this paper demonstrates the development of a simple method for real and reactive power control for the inverters. the method is based on simple circuit theory. For a set values of real and reactive power the magnitude and angle of the inverter output voltage is determined. the PWM technique can be applied to the inverters in order to maintain the calculated operating point. the results obtained from the proposed method have been compared withthose obtained from a detailed method. the agreement proves the accuracy of the new technique.

In this project, an application of gesture mimic human-robot interaction is presented which has been developed using a Kinect sensor. the gesture recognition method combines depth information and traditional joints tracking algorithm using kinect to employ skeleton angular motion in dynamic gesture mimicking. A Master/Slave structured robot control application for master Bluetooth in PC and paired with slave module for the Arduino receiver is developed. the wireless setup provides a favorable function for gesture commands that uses Kinect sensor for controlling of shadow robot. Training session has been utilized for storing the serial string array sets in a Local database of the application which can later be transmitted to the slave at the time it is commanded. A Non-feedback static walking sequence is also been developed for bipedal forward walking of the humanoid robot. Experiment results validate the feasibility and usefulness of the application system.

this paper aims firstly at contributing to the problematic of nonlinear Takagi-Sugeno (TS) approach for state and fault estimation with unmeasurable premise variables. the second objective is the application of this method on Fuel Cell Systems (FCSs). In order to achieve the estimated value of the fault, an observer based method is essential. the development and optimization of Fuel Cell parameter estimation in parallel with fault estimation is not treated in an exhaustive manner in literature. the estimation is based on a PI observer where the estimation error is bounded, having an additional corrective sliding terms. this eliminates the inconvenient generated by the Lipschitz constant.

this study aims to explore the relation between Taiwanese university students' academic hardiness (USAH) and their academic self-efficacy (USASE). An academic hardiness questionnaire and an academic self-efficacy questionnaire were designed, and responses from 320 students from universities in Taiwan were collected. Subjects were divided into two groups: the lower grade consists of 156 responses from freshmen and sophomores, and the higher grade comprises 164 responses from juniors and seniors. USAH questionnaire contains four dimensions: commitment, control of effort, control of affect and challenge. And the USASE questionnaire comprised of two dimensions: self-efficacy and academic self-efficacy. the results indicated strong associations between USAH and USASE. In addition, the result showed that in higher group, three of dimensions of academic hardiness (Commit, control of effort and challenge) could be the positive predictors of the self-efficacy. Moreover, two of academic hardiness (control of effort and control of affect) could be the positive predictors of the academic self-efficacy. Furthermore, in lower group, the result showed that control effort can be a predictor of the two dimension of USASE. And control affect could be a predictor of self-efficacy, challenge could be a predictor of academic self-efficacy.

Multi-functional robot cells will play an important role in smart factories of the future. Equipped with flexible toolings, teams of robots will be able to realize manufacturing processes with growing complexity. However, to efficiently support small batch sizes and a multitude of process variants, powerful software tools are required. this paper illustrates the challenges that developers face in multi-functional robot cells, using the example of CFRP production. the vision of a new programming environment for such future flexible automation systems is sketched.

Renewable energy using a Photovoltaic array (PVA) is becoming increasingly important in present and future world. To controlthe operating point to extract the maximum power (MP) from PV generator is essentially vital as the power generated by PVAs hinges on solar irradiance, temperature and PVA Voltage. To fix the MP point (MPP) of PVA, a good number of algorithms have been presented. One of them is P&O algorithm. However, the likelihood of a false detection of MPP is very high under rapidly changing atmospheric condition. In addition to this, due to change in reference voltage results in steady state oscillation. In this paper, a Modified P&O algorithm is implemented to overcome those problems. the MP&O algorithm is used through the DC-DC converters. this converter is governed by an intelligent controller. Furthermore, the results show that MPPT based on Buck-Boost converter reveals higher efficiency compared to Buck converter. A hardware prototype is used and tested in laboratory.

In this paper we study the application of a domain-dependent heuristic to airport ground traffic control. We consider two variants of the problem. In the first, proposed for the international Planning Competition in 2004, the in-bound and out-bound airplanes have fixed parking and take-off positions. In the second, more realistic variant a controller can assign dynamically for each airplane the runway for take-off or the parking position, such that the total movement of planes at the airport is minimized. We are particularly interested in the second variant, which has an implicitly defined goal state where multiple states could satisfy the goal condition, and the impact of this fact on domain-independent and domain-dependent heuristics. We compare domain-independent heuristics in the Fast Downward planner on this domain to a domain-dependent heuristic.
