Yet this technology still find new applications in several areas including food manufacturing, acceleration of chemical reactions, agricultural post-harvesting processes, extraction and separation of chemical substances, disinfection, etc.. In order to design a microwave heating system for a specific industry, two important steps must be done. The first one is the investigation of the material to be heated referred to as load in terms of dielectric constant and loss tangent. The second step is the lab-scale microwave heating experiment. Mostly, microwave heating systems for experimental use in laboratories are bulky and expensive. As a consequence, numerous researchers in process engineering and food science use modified household microwave oven for doing microwave heating experiments. However, major drawbacks are limited experiment settings and safety of the personnel who are running the experiments due to possible leakage of microwave irradiation from the modified system. This work proposes a microwave heating system for experimental use with a coaxial applicator. As the microwave source, a standard magnetron of a household microwave oven was used.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129203968","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}

However there are many cases in which most of the information covers at some particular components while the rest is worthless. Therefore it is very useful if those significant components can be directly collected instead of wasting bandwidth for the unnecessary ones. Compressive Sensing (CS) is an algorithm that minimizes the sampling rate of the signals while still retaining the necessary information for the reconstruction process. It bypasses the current algorithms in which large amount of data is collected and then remove in a consequent compression step. Every CS algorithms are the combination of random kernels and non parametric estimation techniques. In general, the reconstruction framework estimates an under determined linear system of solutions with an unknown compressible or sparse signals. CS is applied broadly and be a novel algorithm in signal processing including: Channel Coding, Inverse Problem, Data Compression, Data Acquisition and in some fields where hardware has limitation.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121534783","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 cardboard edge images that are strip or slitter and fluted or cut-off side were used for detection and counting. The gray level of edge images which obtain from the line scan camera are convert to binary images by threshoding. After that the strip lines of the slitter side are extracted by the first-order derivative and morphology then processed with MODE for counting. For the cut-off side, the fluted areas of cardboard are identified and measured using Blob analysis. Then the centers of the detected area are located and counted as the number of cardboards. MATLAB is applied to simulate in the experiments for determine the algorithms and perform the real-time experiments using HALCON to see the accuracy and performance of the system. The cardboard type BC, C and B were used in the tests. As experimental results, it is shown that the system provided the correct counting with tolerance of 2 cm and 3 cm in the case of the cardboard placed away further the camera focus for the slitter and cut-off side respectively.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121550074","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 large numbers of villager who reside along the stream side suffer by losing their accommodations, properties, and life. The reason that made flash flood very dangerous is abruptly happening with no proper warning. The flash flood and landslide warning system are developed to forecast and warn the citizens who live in the risky area. Various criteria are selected under the Meteorology theory. This research focuses on measuring the varying of the water level and flow rate of the stream. Sets of sensors are going to be installed along the stream located from the upper stream to the village area. The sensors node has been developed to measure the interesting data. It able to work as a standalone self-powered by photovoltaic cell and as a remote terminal of sensor network system. Each node consists of local controller which is able to process the raw data and the communication module which is functioned to send the information to the server. The industrial control system SCADA (Supervisory Control and Data Acquisition) system is selected to work as a central control program of the warning system. The HMI (Human Machine Interface) is designed based on the contour map of the interest area. The developed system has been tested in two phrases the standalone sensor node and the network test. The laboratory results show that the system able to measure the level precisely and real-time. Each of remote terminals can utilize the power generated by photovoltaic cell sufficiently. The SCADA system can retrieve the information from each sensor nodes correctly.","PeriodicalId":306512,"journal":{"name":"2014 International Electrical Engineering Congress (iEECON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131365459","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}
