In this study, a dynamic hybrid model is proposed for the automatic identification and segmentation of hepatic lesions from CT scans. More specifically, a powerful optimization model for accuracy, speed, and optimal convergence based on kernel fuzzy c-means (FCM), chaotic map, and antlion optimization (ALO) algorithm for automatic hepatic focal lesion segmentation is proposed; named (CALO-FCM). In order to achieve the best cluster centroids and produce more accurate segmentation results, ALO is employed to guide FCM. By balancing exploration and exploitation rates, the performance of ALO is improved in terms of local minima avoidance and convergence speed. It might be argued that the CALO improves computational performance and prevents the FCM from becoming trapped in local minima. The proposed model shows good detection and segmentation outcomes on a set of patients with abdominal liver CT when compared to other methods. Additionally, the experimental findings demonstrated that the proposed model could locate the ideal centroids and avoid the local optima issue. This new hybrid model may lead to an earlier and more accurate clinical diagnosis of a hepatic lesion, assisting medical professionals in their judgement and enabling patients to receive an earlier prognosis.","PeriodicalId":326002,"journal":{"name":"2022 10th International Japan-Africa Conference on Electronics, Communications, and Computations (JAC-ECC)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127288809","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}

Decreasing this time requires fast and accurate accident detection and notification systems. Therefore, existing well-established systems rely on rugged devices, with specialised hardware and accurate sensors to allow for in-vehicle detection and notification. Smartphones have been considered as an alternative mainly due to their much lower cost. In this paper, we show that reliable accident detection can be achieved using main stream smartphone sensors (e.g., accelerometer and gyroscope). The method relies on detecting the accident pulse through using Fourier transform and a random forest classifier. The method also utilises a moving window to incorporate time; and is simple enough to allow for during-accident detection, not requiring the mobile to survive the accident. We have validated the model using the Ollie car-like robot micro accident-testbed and the gold standard in accident simulation, LS-DYNA, achieving a true positive rate of about 96% and true negative rate of 99%.","PeriodicalId":326002,"journal":{"name":"2022 10th International Japan-Africa Conference on Electronics, Communications, and Computations (JAC-ECC)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116319001","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}

Culture and road conditions also affect driving habits. Therefore, automatic detection and reporting of driver behavior to concerned entities can potentially save lives. In particular, we analyze a driving maneuvers dataset collected from one environment (country) but tested in another environment with aggressive driving habits and irregular road conditions. We also develop an on-edge system with fast response time to serve users on a large scale. Specffically, we propose an approach for detecting aggressive and normal events using random forest classifier. We utilize the accelerometer and gyroscope smartphone readings to classify driving maneuvers events to five types (aggressive acceleration, suddenly break, aggressive turn right, aggressive turn left, and normal). We achieved an accuracy of only 63.4% by training our model on an available dataset collected from a foreigner environment and tested on our environment. The lowest precision value was 54% while the lowest recall was 42%. However, we achieved an accuracy of 98.4% when augmenting an available dataset with data collected with our application. The lowest precision value was 98% while the lowest recall was 90%. From the results, it is shown that the available datasets do not generalize well to different driving habits and road conditions. Finally, an implementation of the random forest model using OpenCV on an Android platform is analyzed.","PeriodicalId":326002,"journal":{"name":"2022 10th International Japan-Africa Conference on Electronics, Communications, and Computations (JAC-ECC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115901650","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 because they provide a power-efficient, noncomplex, unlicensed frequency band, safe, and secure solution for data transmission. High data rates up to gigabit per second have been achieved in research over the past years using VLC. However, in order to achieve high data rates in such systems utilizing light emitting diodes (LEDs) already in the infrastructure, it is crucial to mitigate its impairments such as limited frequency response (tens of MHz bandwidth) and nonlinearity. In this paper, a novel transmitter system is proposed to compensate for the two main limitations in LED-based VLC systems. Different pulse shaping Nyquist filtering techniques are applied to minimize inter-symbol interference (ISI) caused by the LED's small modulation bandwidth. Additionally, a preequalizer is presented to alleviate LED nonlinearity. Results show an overall linear transmission and a significant enhancement in symbol-error rates (SER). Moreover, out-of-band side lobes are successfully suppressed, thus requiring smaller bandwidth for signal transmission without loss of information.","PeriodicalId":326002,"journal":{"name":"2022 10th International Japan-Africa Conference on Electronics, Communications, and Computations (JAC-ECC)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116103464","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}
