This paper presents a road traffic estimation method using a GSM mobile phone as a probe. The technique relies on localization by signal strength matching. Our emphasis is on the unusual-large size of the database. We built a module that automatically collects location-signal with one second refresh rate and carried it along a test route to collect database. To handle big database, we additionally present a noise reduction algorithm, which eliminates bad data and compacts the database. For the localization algorithm, the fast nearest neighbor strategy is applied in the database matching to reduce computation time. The position estimations which formerly implemented noise reduction are compared with the ordinary results. Furthermore, we compared the computation time of the fast nearest neighbor algorithm to the normal method. The results show that the mobile phone positioning based on signal strength pattern matching can locate its location down to 63 meter accuracy.

IEEE International Conference on systems, Man and Cybernetics

作者： Sofiene Hermi Taieb Ben Romdhane Raouf Ketata Department of Physics and Instrumentation Engineering National Institute of Applied Science and Technology Tunis Tunisia Research Unit on Intelligent Control Design and Optimization of Complex System (ICOS) National Engineering School of Sfax Sfax Tunisia

This work proposes a new methodology to evaluate and improve the QMS (Quality Management system) effectiveness and efficiency to succeed for a factual approach including all monitoring parameters. This idea is justified by the difficulties incurred by the organizations to establish a continuous improvement's system based on the objectives and the process approach. In addition, the guidelines defined by the FDX 50-174 part published by AFNOR to assess the QMS effectiveness, still guides defining the assessment criteria and progress levels. Indeed, to facilitate the continuous improvement system's integration, we propose a new methodology based on a broad range of monitoring tools (functional and operational indicators, audits, quality control, customer satisfaction) and including the requirements of the process and the system approach.

A new parallel gripping mechanism is proposed in this work. This device has a parallelogramic platform which can be flexibly folded. Therefore, this mechanism not only can be used to grasp an object having irregular shape or large volume, but also can be utilized as micro-positioning device after grasping the object. Forward position analysis and platform kinematics are investigated to deal with motion tracking and force control. Pneumatic rotator is employed for actuation and a compact sized, 4/3 way proportional pressure valve is also developed to deal with feedback-based dynamic control. The pressure valve also allows indirect force control by measuring the offset pressure occurring due to contact between the grasped object and the parallel platform. In experimental work, performances of the motion tracking and indirect force control are shown satisfactory.

In recent years, the quality control of sintered ore has become more and more important for stable operation of modern blast furnaces where the sinter ratio of feedstock material exceeds 50%. The quality control system of sintering plant has been developed by SMI (Sumitomo Metal Industries, Ltd.), which consists of the measurement systems of free carbon and FeO content in raw materials, the control system of particle distribution of crushed coke and the FeO content in sintered ore. It's well known that the conventional batch sampling method has such limitations for quality control of sintered ore as its poor sampling frequency and time lag before result is acquired. In the past several years, SMI has developed the sensors and control system of sintered ore with satisfactory results. Our research in those several years, the following results are attained. (1) There is close relation between indices of ROI (Reduction and Disintegration Index) and TI (Tumbler Index) of sintered products and the ratio of smaller particle size of crushed coke than 1 mm. (2) FeO content of products is controllable by regulating the coke ratio in relation to the FeD content of raw materials and products. (3) FeO content can be controlled more accurately by regulating the coke ratio in which the effect of free carbon content of raw materials is corrected. From those facts, the following measurement systems are developed. (1) Continuous FeO measurement meter for raw materials ----- The principle of FeD measurement meter consists in inductance change of detecting coil by the FeD content of raw materials. (2) Continuous FeO measurement meter for sintered products. (3) Particle distribution measurement system of crushed coke ----- This system uses an optical pattern recognition method. (4) Free carbon content measurement system of raw materials ----- This system estimates the total carbon consumption by calculating the data of flue gas volume and components. The recent operation has obtained th

We propose a system that can record driving events and detect unsafe driving behaviors. Three sensors, an engine control unit (ECU) reader, a 3-axis accelerometer, and a camera are used, in which they represent the car, the passenger, and the driverpsilas perspective. Our system combines data from these three sensors with a fuzzy inference system to identify an event of hazardous driving. The output of the system is the driving risk level ranging from 1 to 3, where 1 is the safest. The output of the system was verified by comparison with a questionnaire from three passengers in a test run experiment.

This paper proposes the novel emotion dynamic equation for emotion implementation like human's emotion. Almost general method use artificial approach such as neutral networks to classify emotion by using speech and face image data for human's emotion recognition. But high-dimension and large size of this data cause low-speed learning in robot system. The main idea of the proposed dynamic equation method is to dynamically express emotion by multi-agent function.

Urban traffic congestion presents critical challenges, resulting in delays, environmental pollution, and significant economic costs. While traditional traffic control methods, such as fixed-time and adaptive systems, have been widely implemented, they often fail in unpredictable conditions, particularly when confronted with noisy or inaccurate data. This research proposes a robust reinforcement learning (RL) solution for traffic signal control using the RADIAL-DQN (Robust Adversarial Loss DQN) algorithm. Integrating adversarial training enhances the system's robustness to real-world uncertainties. Evaluations conducted using a SUMO traffic simulation show that the robust agent produced an increase of only 60.71% in queue length under a projected gradient descent (PGD) adversarial attack, outperforming standard RL agents, which experienced an 89% increase. These results demonstrate the potential of robust RL to improve both the reliability and scalability of urban traffic control systems.
