With the development of construction techniques, the high-rise buildings have been established and populated. In the event of fire in these buildings, as the fire is spreading, the risk of large fire is increased and the resulting casualties and property damages are increased. Therefore, the techniques to detect the flame at an early stage are necessary in order to prevent the fire and minimize the damage. The flame detection technique based on physical sensor has limited disadvantages in detecting the fire early. In addition, this technique has a problem of increasing the cost in proportion to the number of regions where it is installed. Image-based flame detection technique has been studied to complement these problems. In this paper, the object is detected by using the adaptive background modeling technique. In the flame detection technique, the flame is detected by converting RGB images to HSI images which have strength even in the change of lightings or scenes. Also, if the object with similar color to the flame is detected from the output image, it will detect it as a fire, leading to increase the misdetection problem. To solve these problems, objects are classified by using the direction information of the object detected. Based on experiment results, if the flame is detected only using the color information, it is confirmed that the fire is detected in real time. However, the problem of classifying the object as the fire occurred when the object had the similar color to the flame in the image. For this, it is confirmed that the performance was improved when classifying the object using the direction information of the object.

作者： Manikandan Pandiyan Geetha Mani Manikandan P was with Dept. of Instrumentation and Control systems Engineering PSG College of Technology India

The paper presents an analog low power CMOS fuzzy logic controller (FLC) chip implementation and its application to an industrial chemical reactor. This approach employs a simple architecture that contains three stages namely Fuzzification, Inference Engine and Defuzzification. The Fuzzifier circuit generates high precision membership functions (MFs) that are easily tunable by changing the voltages in IC pins. The FLC chip has three input MFs and five output MFs. The two input minimum circuits were used to design the Min-Product inferencing for inference engine. Defuzzification circuit is well designed to reduce the size of the chip. The proposed chip has power consumption of about 10mW. The whole chip area is less than 0.5mm 2 . The resulted chip shows simple structure, good performance in processing speed, also enough flexible to compete digital fuzzy approaches, area consumption and accomplished with less reconfigurable rules, a speed of up to about 8 MFLIPS (Fuzzy Logic Inference Per Second) has been achieved. The results show a good functionality of controller in response to confirm the success of the design. The application of the system to an industrial chemical reactor in a feedback loop is considered.

This paper presents comparison analysis of artificial neural network (ANN) and adaptive neuro fuzzy inference system (ANFIS) artificial intelligence (AI) based maximum power point tracking (MPPT) techniques for tracking maximum power from the Photovoltaic (PV) array. These algorithms are essential since PV arrays have non-linear characteristics with its firm dependence on changing solar irradiation and temperature. To increase the power extracted from solar panel, PV array must operate at a maximum power point (MPP) under given load conditions. Conventional algorithms such as Perturb and Observe (P&O) and Incremental-Conductance (Inc-Cond) suffers, with high oscillations during changing solar irradiation leading to low efficiency, therefore AI based techniques are designed and presented in this paper. ANFIS is more efficient in tracking MPP with less settling time, less overshoot, less oscillations and less time taken to track MPP than ANN based controller.

Energy expenditure of a person closely corresponds to the amount of physical activity. Recently, due to the advance in sensor and electronic technology, we can measure physical activity using portable electronic devices. Smart phones are well equipped with useful sensors such as accelerometers and orientation. In this paper, we present estimation method of activity energy expenditure using a smart phone and use the accelerometer inside a smart phone as a sensitive element able to identify activity.

12th IFAC Workshop on Time Delay Systems, TDS 2015

作者： Pilbauer, Dan Vyhlídal, Tomáš Michiels, Wim Dept. of Instrumentation and Control Eng. Faculty of Mechanical Engineering Czech Technical University in Prague Technická 166 07 Praha 6 Czech Republic Department of Computer Science Katholieke Universiteit Leuven Celestijnenlaan 200A HeverleeB-3001 Belgium

The primary objective is to investigate the applicability of spectral methods for designing feedback controllers for a closed loop system with an input shaper with time delays. The shaper is included in the feedback loop in order to pre-compensate low-damped oscillatory modes of a flexible subsystem. However, after inserting a shaper into the feedback loop, the closed loop dynamics becomes infinite dimensional. A robust controller design then requires guaranteeing that all the infinitely many poles of the closed loop system will safely be located in the left half of the complex plane. Besides, the closed loop dynamics need to be sufficiently fast in order to take over and keep filtering properties of the input shaper. For the spectral design of the controller, the recently developed spectral abscissa minimization approach for interconnected time delay systems is applied. The presented methods are tested on a case study simulation example, which is a multi-degree of freedom mechanical system. © 2015, IFAC (International Federation of Automatic control) Hosting by Elsevier Ltd.

Chlorosulfonated polyethylene (CSPE) was not flooded seawater and flooded seawater & freshwater for 5 days, respectively, and these samples are referred to as BSF(before seawater flooding) and ASFF(after seawater & freshwater flooding), respectively. The apparent density, dissipation factor, relative permittivity, melting temperature, dielectric breakdown time and increased time of applied voltage are higher than those of BSF, but the insulating resistance, dielectric strength, percent elongation and glass transition temperature of ASFF are lower than those of BSF. The differential temperature of those is 0.026 ∼0.028(°C) after AC and DC voltage is applied to ASFF, respectively, and the differential temperature of those is 0.013 ∼0.037(°C) after AC and DC voltage is applied to BSF, respectively. In the case AC and DC voltage is applied to ASFF as well as BSF, the variations in temperature of AC voltage are higher than those of DC voltage. It is investigated that dielectric loss due to dissipation factor(tanδ) is related to electric dipole conduction current. It is certain that the ionic (electron or hole) leakage current was increased by conducting ions such as Na+, a-, Mg2+, SO42-, Ca2+ and K+, those are related to cured atoms of O and S that relatively increased after seawater flooding. © The Korean Institute of Electrical Engineers.

This paper presents the online identification method for interior permanent-magnet synchronous motor (IPMSM) drive system with the maximum torque per ampere (MTPA). The inductances of the motor are identified by recursive least square (RLS) method based on mathematical model, considering the flux saturation state. Using this technique, the improvement of the MTPA trajectory for IPMSM can be implemented along with the effect of magnetic flux. This final paper presents an idea and a procedure of the proposed algorithm. The simulation results are carried out and presented.
