In a simple adaptive control (SAC) theory, several output feedback based control techniques can be applied to the plant satisfying ASPR characteristics. However, real plants do not often satisfy this characteristics. To solve this problem, several PFC design methods have been proposed so far. Most PFC design parameters are generally adjusted by acquiring an empirical knowledge of designers. This article focuses on this situation. If a relative degree of the plant is two, ASPR plants can be designed by modifying an adaptive control input. We perform the effectiveness of the proposed method by some numerical simulations.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"58 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":"124409334","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}

Identification of these parameters is a challenging problem. State-of-the-industry measurement devices allow calculating electrical parameters during electromechanical disturbances. That is why one can use simplified generating unit models, parameters of which can be calculated using field measurements. In particular, generating units damping properties might be estimated. The proposed method involves the synchronous machine damping power estimation by means of the measurements approximation during dynamic disturbances. This value allows determining the generating unit capability to damp power system oscillations. The method was examined in MATLAB Simulink and by means of JSC “STC UPS” physical electrodynamic simulator. One can apply obtained results in the power system emergency control and in a wide variety of problems related to dynamic transients calculation and analysis.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"29 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":"126053275","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 disease is commonly diagnosed by quantifying vertical cup-to-disc ratio (CDR). Therefore, this study proposes two schemes for segmenting optic disc and optic cup based on morphological reconstruction. Retinal vessel removal is considered during the process. The proposed schemes are evaluated on 50 colour fundus images collected from Drishti-GS dataset. The final segmentation results are compared to the available ground truth image. Segmentation of optic disc achieves the level of accuracy, sensitivity and specificity at 96.3%, 83.12% and 99.37%, respectively. The evaluation for optic cup segmentation obtains the accuracy of 99.13%, sensitivity of 80.68% and specificity of 99.53%. These successful results in segmenting optic disc and optic cup indicate that the proposed schemes have a potential to be implemented as part of the development of computerised glaucoma diagnosis systems.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"92 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":"126824583","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}

Employing an automated fertigation system can help farmers by significantly improving water and nutrient usage. The objective is to automatically maintain the moisture level in the soil and to mix different nutrients to obtain the required NPK ratio and give it to plants along with irrigation. This work is carried out in two parts. One is maintaining the optimum level of moisture in the soil. A soil moisture sensor which senses the moisture content in the soil is used. The sensor output is given to the controller, which decides if more water needs to be pumped or not. Then a control system for the fertilizer mixing and delivery part is designed. The user will give the input in terms of how much amount of N, P and K is needed in Kg. The user will also input the concentrations of NPK fertilizer solutions used. Taking all these parameters into account, the system will prepare a fertilizer mixture that contains the required amount of nutrients needed by the plant. It will then deliver the mixture along with irrigation water. The preparation of fertilizer mixture will be done with specific intervals of time which will be decided by the user. The system is connected to internet by using Wi-Fi and the user can enter the parameters in a mobile application which will transmit the data to the system over internet.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"68 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":"126958550","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 is a one-way communication teaching from lecturer to students [5]. Therefore, this way of learning limits students' solving problem skills and their abilities to learn by themselves. This will lead to difficulty situation when students have to manage and solve real problems. This method of learning also obstructs students to develop teamwork skills. Thus this research will explore teaching process by using the project-based management system to develop a team management program. Also, ‘Collaborative Management’ system will use for tracking student's learning behaviors and to support instructional learning by using ‘Problem Based Learning (PBL)’.
