Sky Quality Meter (SQM) was used to measure NSB in unit Magnitude per Square Arc Second (MSAS) while temperature was in Celsius and they were collected in Shah Alam, Selangor. The air quality information was obtained from the Malaysian AQI website. This project investigates the impact of economic and social activities during MCO lockdown to NSB, air pollution and temperature. Within the analysed time frame, the results indicate that there are some effects produced by MCO lockdown to the observed light or NSB, temperature and air pollution. On the average, the NSB, temperature and AQI have decreased by 0.25, 1.55 and 1.0, respectively. This shows that during the MCO lockdown, the air is cleaner and cooler; and the sky is darker which originates from improved air quality due to less air and road traffics; plus less industrial and human outdoor activities.","PeriodicalId":174315,"journal":{"name":"2022 IEEE 18th International Colloquium on Signal Processing & Applications (CSPA)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133492234","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 disease which is likely to affect youngsters below the age of 15 years old can be detected by analysing bone marrow samples. However, the process of extracting bone marrow samples is complicated and this could cause patients to experience discomfort, hence blood samples could serve as alternatives since it also contains white blood cell (WBC) information that was needed in determining acute lymphocytic leukemia (ALL). As the development of ALL is quite fast, the early detection of the diseases is vital; hence this segmentation method was developed. The blood images of ALL patients will first be converted from RGB to HSV and Lab color space before the grayscale images produced used as the input to Otsu by clustering technique resulting in black background images while the cells will be staying in white color. Next, the watershed ridge technique has been used to remove the overlapping cells before retrieving the colored version of the WBC images. The results from testing the image segmentation method using a different component from different color spaces showed that the images applied with component b from the Lab color space proved to produce the clearest image of ALL subtypes compared to the other color components applied as the accuracy produced for B cell, T cell and normal cell were at 99.17%, 99.88%, and 99.92% respectively.","PeriodicalId":174315,"journal":{"name":"2022 IEEE 18th International Colloquium on Signal Processing & Applications (CSPA)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115954482","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}

One of the other remarkable inventions of the present day is the brushless DC (BLDC) motor. The BLDC motors can play a huge role in making the industry most dynamic in the future. It has many advantages over conventional DC and AC motors. However, BLDC motors have been used in various electrical and electronic devices. The BLDC motors need a suitable control driver system to control the speed and torque to get better performance. This study utilizes the MATLAB-Simulink software to develop a combination of propositional integral derivative (PID) controllers that help control the BLDC motor’s speed more efficiently. Enhancement of the capacity of the PID controller is the main agenda of this paper. Finally, the study has undergone some tests to verify whether the BLDC motor using the PID system is more suitable and efficient than other controllers.","PeriodicalId":174315,"journal":{"name":"2022 IEEE 18th International Colloquium on Signal Processing & Applications (CSPA)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116895017","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, due to the different energy outputs according to the weather and solar occlusion by the clouds, this will be a challenge for utility companies to use solar energy effectively. Solar Power Producers (SPP) are also asked to submit solar PV generation forecasts. In this context, our study aims to develop a method of analyzing the percentage of cloud cover based on satellite images of peninsular Malaysia. The Adaptive Threshold method is chosen to be used in this study to classify satellite images. The Adaptive Threshold algorithm is coded in Python to detect clouds and analyze the average percentage of cloud cover in Peninsular Malaysia from 8 am (0800) to 7 pm (1900). The analysis of the average percentage of cloud cover in Peninsular Malaysia is done based on the Frequency Cloud Index which has been identified by the maximum average percentage of cloud cover in Peninsular Malaysia which is from 0% to 60%. The average percentage of cloud cover data in Peninsular Malaysia was used to analyze two (2) case studies. The first case study is an analysis for each month to see the trends, maximum and minimum cloud cover in Peninsular Malaysia while the second analysis is to analyze the trend, maximum and minimum cloud cover in Peninsular Malaysia throughout the year from 5 April 2018 to 16 December 2018. Through analysis made, such an approach is seen can be used as an initial process in making predictions about solar irradiance towards solar energy efficiency.","PeriodicalId":174315,"journal":{"name":"2022 IEEE 18th International Colloquium on Signal Processing & Applications (CSPA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115158895","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, a decentralized e-voting system application capable of verification will be developed in this work using blockchain technology. The Ethereum network and the Truffle framework will be used to implement smart contracts as self-executing electoral agreements. The Ganache (local blockchain) network design demonstrated that the prototype is capable of recording every voting transaction on the network without the use of a central database. The voter can verify the election result by inspecting each voting transaction on the local blockchain. The proposed design will ensure that all voting transactions are stored in a decentralized database, ensuring that no administrative control over the ballot is exercised.","PeriodicalId":174315,"journal":{"name":"2022 IEEE 18th International Colloquium on Signal Processing & Applications (CSPA)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126020064","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}

Thus, to reduce the impact of the landslide’s tragedy, a landslide susceptibility map is needed. The ultimate goal of this paper is to use Geographic Information System (GIS) and machine learning to develop a landslide susceptibility map. In two different landslide-prone areas in Malaysia, the performance of the two different machine learning models, Random Forest and Extreme Gradient Boosting (XGBoost) are evaluated and cross-validated. The Cameron Highland and Penang Island, Malaysia which are the subjects of this study, have a total of 233 and 443 landslides locations, respectively. These landslide locations were randomly divided into 70% for training and 30% for testing. The Digital Elevation Model (DEM), slope angle, slope length, Normalized Vegetation Index (NDVI), plan curvature, profile curvature, distance from the stream, distance from roads, Topographic Wetness Index (TWI) and Stream Power Index (SPI) are among the ten landslide conditioning factors, for which the spatial databases were developed by using GIS software. The area under the curve (AUC) of the receiver operating characteristic curve (ROC) had been applied to evaluate the machine learnings prediction accuracy. The result indicated that both XGBoost and Random Forest had a great performance across both study areas. For Penang Island, the AUC of XGBoost is 95.02% and the AUC of Random Forest is 94.99%. Meanwhile, for Cameron Highland, the AUC of XGBoost is 91.99% and the AUC of Random Forest is 92.32%. The final prediction map from this study might be useful for better planning in mitigating the occurrence of landslides.","PeriodicalId":174315,"journal":{"name":"2022 IEEE 18th International Colloquium on Signal Processing & Applications (CSPA)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131151676","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 study aims to determine the optimum parameter of ferrous particle size for MRE to obtain the maximum impact absorption capability performance. In order to develop MRE, the composition of MRE RTV silicon rubber, hardener, and CI particles with size of 20, 40, and 60 μm are investigated. In real-life applications, the optimum performance of MRE is influenced by the size of ferrous particles. Therefore, the preparation of MRE material is evaluated through experimentation to obtain optimum MRE composition parameters. In this study, three models of isotropic MRE were tested in off-state and on-state conditions with input current values of 0A, 0.5A, 1A, 1.5A, and 2A. The impact test machine was used to validate its performance in impact absorption capability. Validation of the performance is done by evaluating the response of the damping force of MRE material. As a result, this study proves that the size of Carbonyl Iron particles and the value of injected current can affect the response of damping force of MRE. Since the impact absorption capability of MRE can be determined by the response of damping force, the optimum size of CI particle to absorb the maximum impact is determined in this experiment. Therefore, the objective of this study is justified by finding the optimum CI particle size for best impact absorption capability, which is 60 μm in on-state condition with 2A input current.","PeriodicalId":174315,"journal":{"name":"2022 IEEE 18th International Colloquium on Signal Processing & Applications (CSPA)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128257348","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}
