Teleoperation is a mechanism that makes it possible to accomplish a task in an environment where the presence of the master at the slave site is either undesirable or hardly possible The communication delay is a challenge with undesirable effects, jeopardizing the teleoperated systems the most. When the salve agent is performing in a dynamically changing environment, communication delay can be very harmful since the environment is changing continuously even though the agent has stopped operating because of the delay. Many studies have been conducted to overcome time delay effects.

A coding style-based plagiarism detection

A coding style-based plagiarism detection

International Conference on Interactive Mobile and Computer Aided Learning (IMCL)

作者： S. Arabyarmohamady H. Moradi M. Asadpour Advanced Robotics and Intelligent Systems Laboratory & Control and Intelligent Processing Center University of Tehran

In this paper a plagiarism detection framework is proposed based on coding style. Furthermore, the typical style-based approach is improved to better detect plagiarism in programming codes. The plagiarism detection is performed in two phases: in the first phase the main features representing a coding style are extracted. In the second phase the extracted features are used in three different modules to detect the plagiarized codes and to determine the giver and takers of the codes. The extracted features for each code developer are kept in a history log, i.e. a user profile as his/her style of coding, and would be used to determine the change in coding style. The user profile allows the system to detect if a code is truly developed by the claimed developer or it is written by another person, having another style. Furthermore, the user profile allows determining the code giver and code taker when two codes are similar by comparing the codes' styles with the style of the programmers. Also if a code is copied from the internet or developed by a third party, then the style of who claims the ownership of the code is normally less proficient in coding than the third party and can be detected. The difference between the style levels is done through the style level checker module in the proposed framework. The proposed framework has been implemented and tested and the results are compared to Moss which shows comparable performance in detecting plagiarized codes.

In this paper we address the task of throwing an object on a plane using a wheeled-tip robot. Wheeled-tip robots constitute of one or more artificial fingers with an active wheel at the end of each finger that acts as its fingertip. This class of robots may be used for the task of transfer-throwing objects. In this task, the robot transfers the object for a while, giving it required velocity and then throws it toward a defined goal. The use of wheeled-tip robot in a transfer-throwing task has some advantages in practice and with respect to a typical robot. The wheel at the tip of the robot finger can move independently on the object and gives it the desired velocity at the time of throwing the object. Here we present an algorithm of a planner for throwing objects on a plane using a wheeled-tip robot. We show how using the ability of moving the wheel on the object leads to capability of overcoming joint velocity limits, making this class of robots proper for doing the task.

Due to rising value of energy supplies, the need for managing electrical energy sources becomes prominent. In this paper, a smart plug device is presented; which provides features to measure energy consumption and recognizes the type of attached electrical devices. Furthermore, the proposed framework enables home controller systems to monitor and control home energy consumption efficiently. Subsequently an analysis of energy consumption of a pilot house, prior and after the installation of the smart plug, based on a hypothetical scenario, is provided. The results present positive impacts of using the smart plug on energy consumption rate; especially during peak hours.

Smart performance evaluation of Distribution Network Operators (DNOs) is an essential part of their effective governance task. This paper focuses on benchmarking twenty one districts of the Greater Tehran Electricity Distribution Company (GTEDC) using Data Envelopment Analysis (DEA). Three methods are employed, namely: CCR (Charnes, Cooper, and Rhodes), SBM (Slack Based Measurement), and WSBM (Weighted Slack Based Measurement). The results consist of efficiency scores of CCR, SBM, and WSBM with slacks analysis for the latter. Based on the WSBM results, weak districts are clarified and necessary improvements are suggested.

作者： Saleh Mobayen Mohammad Javad Yazdanpanah Vahid Johari Majd Intelligent Control Systems Laboratory School of Electrical and Computer Engineering Tarbiat Moalem University Tehran Iran Control & Intelligent Processing Center of Excellence School of Electrical & Computer Engineering University of Tehran Iran

A novel recursive singularity free FTSM (Fast Terminal Sliding Mode) strategy for finite time tracking control of nonholonomic systems is proposed. As a result, the singularity problem around the origin resulting from the fractional power of conventional terminal sliding mode is resolved. Simulation results are given for two benchmark examples of extended chained-form nonholonomic systems: a wheeled mobile robot and an underactuated surface vessel. The results show the effectiveness of the proposed strategy.

Wireless signal fingerprints have been used to localize mobile devices in recent years. Especially, WLAN signals are of great importance, because of the ubiquity of WLAN infrastructure. In this paper, the possibility of correlation between temperature and signal strength is investigated to improve the traditional fingerprinting method by incorporating the temperature into the process. The new approach is called the Temperature-Aided Fingerprinting (TAF) and even with current WLAN-enabled devices, which usually do not have a thermometer, TAF achieves a better performance than the traditional method. At the end, we open up a hypothesis that the observed difference is not caused by the temperature, rather by the crowdedness and the dynamics of the environment. This is left to be investigated in the future.

Representing an image as a set of its key and interesting lines facilitates the image understanding and classification. In this paper, we propose a method to extract the significant and interesting lines of the scene, which probably are useful in image classification. The proposed method is inspired from the Visual Attention, which is a perceptual mechanism in human and other primates that direct their perceptions to the limited regions of the scene. The attended regions are usually valuable in performing the task. Since the approach of using the lines to classify the images is particularly useful for omnidirectional images, we specialize our method to deal with these kinds of images. In the experiments, we demonstrate how our proposed methods improve the image classification performance with processing only small parts of the input images.

International Conference on control, Instrumentation, and Automation

作者： N. Hassanpour M. A. Zamani A. Fereidunian H. Lesani Systems and Machines Research Laboratory (SMRL) Control and Intelligent Processing Center of Excellence (CIPCE) School of ECE University of Tehran Tehran Iran Electrical and Computer Engineering Department K. N. Toosi University of Technology Tehran Iran

We earlier introduced a novel framework for realization of Adaptive Autonomy (AA) in human-automation interaction (HAI). This study presents an expert system for realization of AA, using Support Vector Machine (SVM), referred to as Adaptive Autonomy Support Vector Machine Expert System (AASVMES). The proposed system prescribes proper Levels of Automation (LOAs) for various environmental conditions, here modeled as Performance Shaping Factors (PSFs), based on the extracted rules from the experts' judgments. SVM is used as an expert system inference engine. The practical list of PSFs and the judgments of GTEDC's (the Greater Tehran Electric Distribution Company) experts are used as expert system database. The results of implemented AASVMES in response to GTEDC's network are evaluated against the GTEDC experts' judgment. Evaluations show that AASVMES has the ability to predict the proper LOA for GTEDC's Utility Management Automation (UMA) system, which changes in relevance to the changes in PSFs; thus providing an adaptive LOA scheme for UMA.
