Under GPS-denied environment, non-unique landmarks such as traffic signs can be used as alternative absolute position information. However, such landmarks lead to ambiguous correspondence between landmarks and their features. For a robot to successfully localize itself, this ambiguity should be tackled. To solve the problem, a multiple hypothesis testing method is adopted. As robot detects other landmarks, the number of the hypotheses can be increased exponentially. The nearest neighbor filter technique is applied to prevent the number increase. The capability of the suggested algorithm is examined based on a computer simulation.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121091137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PI controller is designed based on Cohen-Coon tuning algorithm. The temperature and humidity sensors are connected with FiO Glide boards to send data to the micro-controller STM32F4 with radio frequencies to control temperature and humidity appropriately by using the PI algorithm and send signals for control the fan and fog sprayer. The size of greenhouse is 2×3×2 meters. The experimental results show that, the PI controller base on microcontroller STM32 can be controlled the inside temperature is lower than the outside temperature of 4 degrees Celsius.

Presently, many industries, research organizations and universities are working on intelligent vehicles. Some researchers are working on security issues of intelligent vehicles (IV). Most of the researchers focus on static security (static security cannot adapt to the changes in the environment). Since the environment of IV is dynamically changing, the approach of static security is not feasible to provide reconcile cyber-security in IV. Reconciling systems evolve in a very uncertain environment and try to fulfill a business objective by sensing the environment, analyzing it and taking the best decision according to its requirements. In this paper, we discuss reconcile security requirements engineering to provide cyber-security in IV. To fulfill our objective, we use the goal modeling approach of RE, the Knowledge Acquisition in Automated Specification (KAOS) Model approach, and designed it using Objectiver tool to find the reconciling requirements. Self-reconciliation in requirement engineering is acquired by five building blocks such as Monitor, Analyze, Plan, Execute and Knowledge i.e. [MAPE-K] loop architecture, which provides the reconciling capabilities to our proposed reconciling requirements for cyber-security in IV.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126359873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, there is a growing demand for technology that can be used to evaluate the performance of face recognition capable of ensuring reproducibility and objectivity in real service environments. The best way to replace real faces for performance evaluation is to use the facial image output from a display device. Previous studies have reported no significant difference between recognition performance for real faces and facial image output from a display device. However, the question remains whether a difference exists between two images at the low levels; if it does, then how does it affect face recognition performance? To answer these questions, the current study shows color differences before and after the adjustment by using color as a representative feature at the low level, and validates the proposed evaluation method by comparing the differences in recognizing two images.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129110328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This system can help patients self-control his meal replacement for the care of a family member or care worker thereby saving a lot of time and effort of caregivers, and, nutritional management software of each meal will allow caregivers understand nutritional information of the patients in the diet which can not change to improve the quality of meals for patients. The self-feeding system is experienced and evaluated with several cases in nursing home to give suitable design. The experimental results show that this self-feeding system provides a viable alternative to assisting independence in self-feeding as measured by ingesting time and nutrition intake. The self-feeding system is operated autonomous by itself and sent food's data and relative information to monitoring computer based on Internet.

This part is used in smart buildings and provides the desired air quality and thermal comfort. The time delay and uncertainty in model parameters due to the several operation mode cause the main challenges in heating system control by the traditional PID approaches. To overcome these problems, this paper presents an intelligent PID algorithm combines the fuzzy logic and neural network method together and used it in Smith predictor structure. Hence, a fuzzy neural network PID controller based on Smith predictor is proposed in this paper for the heating system. By correction of the dynamic learning of neural network and fuzzy inference, PID parameters of the controller get their optimal values. Simulation results of the heating system illustrate that the performance of the fuzzy neural network PID controller based on Smith predictor in comparison to the other control structures has been greatly improved, with fast response, smallest overshoot and lowest rise and settling time.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"533 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134127923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since it is the first step of the study, we assume that eyes are in the near-field and all the motions, except eyelid movement, are fixed. The measurement of eyelid movement can be utilized in a human computer interface or for the recognition of a driver's drowsiness. If the eyelids move up or down, the amplitude and frequency of radar signals change. We can observe these changes in a three-dimensional graph of raw radar data. Intentional eyelid movements produce some peaks or nulls on the graph. We used two methods to analyze the patterns of eyelid movement. Both methods involve fast Fourier transform (FFT) and exploit a pulse Doppler processing technique of radar signals. Thus, we can calculate the frequency of intentional eyelid movement using these methods. The calculated frequency corresponds to the number of peaks in the raw radar graph.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133041391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because they have advantages of low noise, simple control and high power density. But, in a high-speed motor drive, current lagging which is induced by the impedance of the motor inductor reduces the motor efficiency. To solve this problem, we propose an auto lead angle control algorithm based on a gradient descent algorithm. With this algorithm, the motor current and motor Back-EMF have an identical phase angle. Thus, the efficiency of the motor can be increased. In order to verify the proposed algorithm, we implemented the hardware with FPGA and board including analog circuit. As a result, it was confirmed that the optimum lead angle was found with only one current value without various parameters, and the efficiency of the motor was improved. Also, it is confirmed that the efficiency is further increased at high load and high speed.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127710267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
