System level low power optimization can significantly decrease the power consumption and increase system lifetime. Further, energy scavenging technologies have been proposed to improve the lifetime of such a system, up to perpetual operation. However, fixed duty cycle (active/sleep) operation can cause inefficiencies in the presence of variable input power; further, in cases of limited storage capacity and intermittent input power, the system’s perpetual operation is not guaranteed. Energy forecasting algorithms can propose adaptable duty cycles, at the expense of heavy computing workloads. In this paper, we propose adaptable duty cycle operation for energy efficient IoT sensor nodes, utilizing a very simple -and very lightweight - scheduling algorithm that depends only on the periodical provision of the accumulator’s state-of-charge. The proposed algorithm achieves energy balance in the presence of harvested energy and guarantees a minimum operation time in the absence of harvested energy.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"3 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89777094","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 obscene words usually have a meaning, which is associated with offending social acquaintances often based on locality or sexuality. This results in a patient’s social isolation and increased anxiety. The patient finds herself stopping things that she would do in her everyday life. In this work, we aim to explain the Coprolalia symptom with the means of bipartite graph matching. We assume that the brain network performs some kind of rerouting of thoughts, which results in the association of normal thoughts with their matched obscene ones. With this we aim to decode the operation that results in Coprolalia, in order for the patient to be informed of this behaviour. Furthermore, we propose a game-theoretic model based on the Battle of the Sexes, which has two equilibria in the pure strategies, namely to jam the intrusive coprolalic thoughts or to pass through the brain. In this way, we provide a mechanism for the patient to stand in social activities, in which the symptoms are severe. Moreover, we align with Cognitive Behavioural Therapy (CBT), with which intrusive thoughts pass through the brain with the aim of deteriorating.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"1 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91305252","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 methodology developed aims to the identification of basic emotions by using an electroencephalogram through an experimental process where participants were asked to evaluate the experiment according to the valence, arousal and dominance of each emotion inflicted on them by videos they were subjected to watching. Through the experimental process, a vector of characteristics is analyzed for each of the electrodes of the electroencephalogram and for a series of videos.

Prior to applying these models, image preprocessing techniques are applied in order to improve the detection results. However, there is a lack of computational comparisons on the application of different image preprocessing techniques before applying object detection algorithms for plant disease detection. This paper aims to fill this gap by presenting a computational comparison of seven different image preprocessing techniques (auto-orientation, object isolation, resizing, grayscale conversion, static crop, contrast adjustment, tiling) applied prior to the execution of two state-of-the-art object detection algorithms, one single-stage detector, YOLOV5, and one two-stage detector, Faster-RCNN. We investigate whether or not these preprocessing techniques improve the accuracy, training time, and inference time, of plant disease detection. Apart from comparing these techniques solely, we also perform combinations of the preprocessing techniques. The PlantDoc dataset was used for this experimental study. Computational results show that the best method improves the mean average precision by 9% and 3% for YOLOv5 and Faster-RCNN, respectively. Finally, the combination of all seven preprocessing techniques yields an improvement of about 13% in the mean average precision of both object detectors.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"54 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86872451","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}

Such low power requirements can be fulfilled in indoor environments -even with low light irradiance-by utilizing specialized PV cells. This has created the need for rigid PV cell validation in representative low light conditions. In this paper we investigate the design of a light simulator using low-cost LED components. We propose a process to determine the number and positions of the LEDs in order to fulfill intensity and uniformity requirements.
