They are experts in suppressing the sway motion which is generated in the process of the handling. This undesirable motion may deteriorate the operation efficiency due to strained nerves of the operator. To overcome this problem, we propose an anti-sway controller with an image sensor for a container crane. The image sensor measures the displacement of the spreader. Especially, the measured displacement is in real time fed back to the controller. The image processing technique here is a kind of robust template matching method, named Vector Code Correlation (VCC), devised to consider the conditions of real environments. The anti-sway controller is installed on the spreader. The controller has a role to suppress the sway motion of the spreader, as soon as possible. We employ the simple mechanism, so that it can be easily applicable to an existing system. The details and performance of the container crane system is introduced together with the experimental results performed with the model system. In this paper, we will also show that the system has the sufficient efficiency and accuracy for the use on practical job-site.","PeriodicalId":250590,"journal":{"name":"ICMIT: Mechatronics and Information Technology","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125734557","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}

To simplify the testing, we develop a framework that composes of interface rules, procedures calling mechanisms and test cases management system. The framework will help to create the testing simulator for the ACS software easier and faster while minimizing the possible errors. There are some assumptions needed to be met before the framework can be applied to the ACS software development situation. It also provides the testing simulator a standard way to record the testing data, results and debugging information. The framework itself is developed based upon XML technology which can be parsed by many tools easily. After the ACS software is developed, it will be tested basing on the test cases during the software implementation phrase, integration phrase and deployed phrase. Furthermore, the drawbacks for the framework applications will be discussed while the valuable suggestions provided. At last, a simplified example of oil refinery control system software will be illustrated how the framework be used, the rules how to be set and followed.","PeriodicalId":250590,"journal":{"name":"ICMIT: Mechatronics and Information Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121941936","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}

Considering the different frequency distributions between the normal sound and insufficiency murmurs in frequency domain, we used two properties such as the relative wavelet energy and the Shannon wavelet entropy which described the energy information and the entropy information at the selected frequency band, respectively. Then, the signal to murmur ratio (SMR) measures which could mean the ratio between the frequency bands for normal heart sounds and for aortic and mitral insufficiency murmurs allocated to 15.62-187.50 Hz and 187.50-703.12 Hz respectively, were employed as a classification manner to identify insufficiency murmurs. The proposed measures were validated by some case studies. The 194 heart sound signals with 48 normal and 146 abnormal sound cases acquired from 6 healthy volunteers and 30 patients were tested. The normal sound signals recorded by applying a self-produced wireless electric stethoscope system to subjects with no history of other heart complications were used. Insufficiency murmurs were grouped into two valvular heart defects such as aortic insufficiency and mitral insufficiency. These murmur subjects included no other coexistent valvular defects. As a result, the proposed insufficiency murmurs detection method showed relatively very high classification efficiency. Therefore, the proposed heart sound classification method based on the wavelet packet was validated for the classification of valvular heart defects, especially insufficiency murmurs.","PeriodicalId":250590,"journal":{"name":"ICMIT: Mechatronics and Information Technology","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114655753","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 relationships between the states with desirable responses can be expressed by some functions and these functions are estimated by using SVM. There are classification problems and regression problems in support vector machines. Only the support vector regression problem is used in this paper. This paper proposes a very novel method which makes it possible that state feedback controller can be designed for unknown dynamic system with measurable states. The SVR algorithm is used for the identification of inputoutput relationship. A virtual state space representation is derived from the relationship and the SVM makes the relationship between actual states and virtual states. For unknown dynamic systems, a state feedback controller can be designed based on the virtual system and the SVM makes the controller being with actual states. The results of this paper can give many opportunities that the state feedback control can be applied for unknown dynamic systems. The first step of this design method is to identify the input-output relationship of the unknown system as a transfer function by using SVR. Next step is to design a virtual system based on the transfer function. Final step is to derive the relationship between the actual states and virtual states by using SVM. The linear kernel function is used in SVR. A state feedback controller is designed based on the virtual system and the virtual system can be replaced by actual states by using the above relationship and it gives the actual states feedback controller. And simulation results are provided to show the performance of the proposed control method. Finally, the results of this paper make it is possible to the state feedback control theory to be used for unknown dynamic systems. This result can be expected to be applied to unknown nonlinear systems.","PeriodicalId":250590,"journal":{"name":"ICMIT: Mechatronics and Information Technology","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114896028","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}
