Human Robot Interaction To Guide a Person
(IEEE, 2018) Erdoğan, Kemal; Kömür, Hasan; Durdu, Akif; Ceylan, Rahime
Some people need to be guided in various cases. If this guide is a robot, there will be an interaction between human and robot. In this study, an experiment made with 15 people to show that an interaction could be established between the human and a robotic arm which is aiming to guide the human to solve a simple puzzle. Three objects were used in the experimental setup. Objects were chosen in the shape of rectangular prism and each has different size and color. A Kinect sensor was used to monitor and record the experiments. Also with these records a dataset was created which could be used for jobs like object recognition and object tracking. A six axis robotic arm was operated with an algorithm which was modeled by Finite State Machine (FSM). In the end of experiments users were asked to fill in a questionnaire. According to the answers and records it is concluded that an interaction occurs between a robotic arm and human easily. %73.33 of the users got the message from robotic arm and solved the problem successfully.

Mitigation of Voltage Unbalance in Microgrids Using Thermostatically Controlled Loads
(IEEE, 2018) Çimen, Halil; Çetinkaya, Nurettin
With the development of technology, some important developments occur in electrical energy systems. Especially smart grids and micro grids will be an important part of energy systems in the following years. With the increasing use of micro grids, more renewable power plants will be included in the system. However, the production of renewable energy sources varies according to the weather conditions. Therefore, the generated energy is not known beforehand. Increasing single-phase loads (such as electric vehicle charging stations), unpredictable renewable generation and uncertainty of consumption can lead to problems of voltage unbalance in the micro grid. This problem can damage the network in many ways. In this study, the problem of voltage unbalance occurring in the microgrid was tried to be reduced by demand side management. The comfort of the customer should not be affected when demand side management is performed. For this reason, the most suitable load for demand side management is thermostatically controlled loads (TCL). An algorithm has been proposed to reduce voltage unbalance by using these loads. This algorithm was tested with the help of PSCAD/EMTDC program.
Usability of Turkish National Gnss Permanent Network-Active Points for Detecting Deformations
(IEEE, 2018) Gündüz, Ahmet Mete; İnal, Cevat; Yıldırım, Ömer
Measurement and analyzing of deformations are one of the important subjects of geodesy. The effects of possible damages can be decreased by determining the deformations on earth crust and engineering structures. Both to lower the operating expenditure and to be assumed that there is no deformation during the measurement period, deformation measurements should be performed in a short time. At the present time, GNSS technique is used commonly to determine the deformations. In this study, it was investigated the usability of the Turkish National GNSS Permanent Network-Active (TNGPN-Active) points to determine the deformations. For this purpose, a pillar was established on the garden of Kutahya Environment and Urban Ministry Provincial Directorate. A mechanism which is for creating virtual deformation on the pillar was produced in high accuracy by using CNC machining center. The GNSS receiver was placed on the levelled mechanism and shifted with 1 cm interval along 20 cm on East-West, North-South and vertical directions. The GNSS measurements which were collected for 24 hours on the mechanism were adjusted based on the TNGPN-Active points which names are HARC, BILE, KUTA, ESKS, EMR1, AFYN, USAK, DEIR by using Bernese v5.2 Scientific GNSS software. The GNSS data which were collected were separated 6, 12 and 24 hourly parts while it was being processed. For any situations, cartesian coordinates of the points (X, Y, Z) and their root mean square errors (rmse) were calculated. The deformation analyses were performed for each situation by using the cartesian coordinates and the rmse. At the end of the analyses; it was reached the consequences that by using 12 and 24 hourly data which have 30 seconds data record interval is able to determine for 1 cm deformation on horizontal direction, by using 24 hourly data is able to determine for 1 cm deformation on vertical direction. In addition, the cartesian coordinates were transformed to projection coordinates for the purpose of comparing the shifting amount with the value which was calculated with measurements, the amount which was calculated from coordinates had been compared with the amount which was given as virtualy. At the end of the comparing, it was seen that when the measurement time increases, the virtual shifting amounts and the calculated values get closer to each others.
