Convolutional Neural Networks (CNNs) have exhibited promising outcomes in automatically detecting epileptic focus through the analysis of intracranial electroencephalogram (iEEG) signals. However, the limited availability of labeled iEEG dataset, which require specialist annotations, has constrained the effectiveness of CNNs. In this study, data augmentation techniques, including time shifting, amplitude scaling and noise addition, were employed to enhance the diversity and information content of the data. These techniques aimed to enable machine learning models to extract features from various aspects of iEEG data, thereby improving the accuracy of the models. Three deep learning models, namely DeepConvNet, ShallowConvNet and EEGNet, were introduced for the identification of epileptic foci. To evaluate the proposed methods, the Bern-Barcelona iEEG dataset was utilized. The experimental results demonstrated that the augmented dataset, formed by applying the three data augmentation techniques, achieved higher accuracies across all three deep learning models compared to the original dataset. This finding underscores the feasibility and efficacy of the proposed data augmentation and feature extraction methods in automated epilepsy detection.","PeriodicalId":210853,"journal":{"name":"INTERNATIONAL JOURNAL OF COMPUTERS & TECHNOLOGY","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114038579","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}

Boyd","doi":"10.24297/ijct.v23i.9371","DOIUrl":"https://doi.org/10.24297/ijct.v23i.9371","url":null,"abstract":"Every discussion of quantum computing starts with wave-particle duality, to explain how qubits differ from bits. But what if wave-particle duality were wrong? How would we explain quantum computing then? A little-known science called the Theory of Elementary Waves (TEW) says that quantum particles follow zero-energy waves backwards. Wave-particle duality cannot be true if waves and particles travel in opposite directions. This article proposes the first-ever TEW theory of quantum circuits. Elementary waves emanate from measuring devices and travel backwards through the circuits, whereas qubits move forwards through the wires and gates following those waves backwards. Quantum computers are known to be reversible. After we present that way-of-thinking, we will explain some of the evidence that TEW is valid. There is a mountain of empirical evidence from outside information technology. TEW is a maverick theory, out-of-step with the consensus about how quantum computers work. At first TEW sounds counterintuitive. Its advantage is Occam’s Razor: we present a simpler explanation of quantum circuits. We will present the quantum computer equivalent of saying that before the box is open Schrödinger’s cat is already dead or alive, but not both. Observing the cat simply tells us what was already true before we looked.","PeriodicalId":210853,"journal":{"name":"INTERNATIONAL JOURNAL OF COMPUTERS & TECHNOLOGY","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132209874","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, endoscopic entry via a burr hole has recently gained significant traction in the practice of neurosurgery. High-resolution endoscopic images are possible with limited admittance of accessory tools and instruments. Although brain tissue can be removed easily with a suction device, but it will be uncontrolled ‘excision’. The Rotitome-G is a precision micro-endoscopic target access surgical instrument. It has several accessories for intraoperative assessment and precise removal of the soft tissue lesions pixel-by-pixel within a closed body cavity through a single portal.\u0000Objective: This preliminary theoretical research study on Rotitome-G is transition to experimental cadaveric and clinical studies. It describes the construction and mechanics of this newly conceptualized robot-assisted microsurgical endoscope. The design includes precise excision at the pixel and microscopic level and removes tissue debris under computer-aided navigation and direct instrument vision. Currently, the primary objective is to interest both the neurosurgeons and biomedical engineers, hence its contents are diverse resulting in an extended text.\u0000Methodology: The study provides the basics of computer vision techniques and neuronavigation to establish the function and application of the Rotitome-G. The structure and kinematics of the animalcule Rotifer have been considered followed by the construction of Rotitome-G. For a better understanding of intracranial tumour excision, the article examines the role of intra-operative imaging, biomechanics of brain tissue, and brain shift to better understand the principles of this newly conceived  microsurgical instrument. The functional capabilities of the instrument have been putatively demonstrated by describing the excision of a glioblastoma.\u0000Conclusion: It is expected that the key design of Rotitome-G would meet the goal of neurosurgical resection by excising maximum amount of pathological tissue. Direct microscopic resection will prevent damage to the eloquent areas to improve the prognosis by limiting neurological morbidity. Clinical validity of the Rotitome -G remains to be determined.","PeriodicalId":210853,"journal":{"name":"INTERNATIONAL JOURNAL OF COMPUTERS & TECHNOLOGY","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114633672","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 a notion demands the need for individualization of treatment and a method to select an ameliorative implant prospectively. One such empirically testing method is the finite element-n-of-1 (fe-n-of-1), where a treatment plan is executed specifically and systematically for a single patient as part of pre-operative planning.\u0000Objective: It is to evaluate and discuss the method of finite element analysis to carry out the fe-n-of-1 empirical test in a fact-driven manner connecting various scientific domains. It presents a preliminary protocol how to select an ameliorative implant to mitigate sternal instability due to suboptimal standard stainless-steel cerclage wiring to reconstruct the sternum following open-heart surgery. \u0000Methodology: The instability following the reconstruction of the sternum is a mechanical problem therefore it is appropriate to apply harmless structural engineering methods to choose a suitable implant design to fix it. This exploratory descriptive research describes finite element n-of-1 empirical testing using in-silico engineering principles applied to patient-specific and patient-appropriate mechanical loading conditions.\u0000Conclusion: Single-patient fe-n-of-1 empirical testing is a benign engineering method based on finite element modeling and finite element analysis. It is a safe mathematical evaluation free from subjective bias to select in advance the most ameliorative implant design to opt out of the suboptimal stainless steel cerclage wire as ‘standard of care’ and improve patient-based outcome and surgeon satisfaction. ","PeriodicalId":210853,"journal":{"name":"INTERNATIONAL JOURNAL OF COMPUTERS & TECHNOLOGY","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114419548","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}

Research is therefore being performed on a software performance estimation technique that uses the IEEE2804-2019 hardware feature description called software-hardware interface for multi-many-core (SHIM).
