Solar lamp posts deployed in streets and highways are neglected most of the time. This constitutes a huge waste of government budget. The development of a health monitoring system for a solar lamp post will help data recording without personnel presence. The results show that the end-user can view the health status of the post including battery, solar panel, and LED lamp, anywhere as long as it is connected to the cloud. The modem sleep mode in the microcontroller decreases the power consumption of the system while transmitting the data via wi-fi or Wimax technology.","PeriodicalId":194655,"journal":{"name":"2021 IEEE 17th International Colloquium on Signal Processing & Its Applications (CSPA)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115423672","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 performance chart and returns table are available from the factsheet of the fund, which can be used to evaluate the performance of the fund. However, the rolling returns, which is not given, may be a better indicator of the fund's long-term performance consistency. A semi-automated software application was developed to determine the rolling returns of a mutual fund from its published performance chart. Because the published chart is in rasterized image format, image processing was applied to extract the data. Some manual input is required from the user, including the initial and final dates, values and points, and loading an image of the performance chart. The image is converted into hue-saturation-value format and cropped. Thresholding and morphological operations are then performed to obtain a binary image. The graph is detected by finding the contours and the x-y data points extracted. The data, together with the information input by the user, are used to calculate the rolling returns. From our evaluation, the average error for 5-year rolling returns was an absolute difference of 3.63 between the actual and calculated percentage values.","PeriodicalId":194655,"journal":{"name":"2021 IEEE 17th International Colloquium on Signal Processing & Its Applications (CSPA)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127261564","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, difficulties come to obtain a good image from a camera that mounted on a moving object due to vibration issues. Therefore, the use of an effective controller is required to eliminate disturbances hence ensuring gimbal stability. This leads the development proposed to two degree of freedom (2-DOF) gimbal system. The 2-DOF gimbal system contains of two stabilization loops referring to elevation and azimuth. The research work is divided into three stages. The nonlinearities effects such as torque, inertia and momentum are considered in mathematical modelling using Newton's law and Euler approach. Then, the PID controllers are design while the impact of the base angular velocity and the base angular motion of the gimbal system are investigated for six scenarios. Overall, superior control performances are resulted by PID controller and it was proved by the minimum overshoot and rise time recorded.","PeriodicalId":194655,"journal":{"name":"2021 IEEE 17th International Colloquium on Signal Processing & Its Applications (CSPA)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124374442","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 key improvements to the COAWST vegetation package are: (1) allowing the vertical varying projected area density (frontal area per unit plan area), (2) using the root and stem length-scales in the turbulence dissipation terms, (3) implementing the Rhizophora module which can calculate projected area density from easily obtainable field measurements. These improvements allow the field to move beyond the conventional cylinder assumption, and are generally applicable to all hydrodynamically rough environments which aren’t well described by cylinders.","PeriodicalId":194655,"journal":{"name":"2021 IEEE 17th International Colloquium on Signal Processing & Its Applications (CSPA)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117133408","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}
