The process constitutes temporary permeabilization of the plasma membrane by creating high electric fields at the tip of commercially available tapered tungsten electrodes. Subsequently, various electrical field frequencies were tested to quantify the insertion and release of dye molecules through the transient pores. Using optimized settings, we have also successfully managed to insert a plasmid to induce fluorescent protein expression, via a process referred to as transfection. The proposed design overcomes technological disadvantages of conventional cuvette-based electroporation, by creating a rapid sequentially addressable open-fluidic platform requiring small fluid volumes capable of handling multiple reagents.","PeriodicalId":433404,"journal":{"name":"Proceedings of the 7th World Congress on Electrical Engineering and Computer Systems and Science","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121514791","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}

{"title":"Investigation of Two Double Throws and Three Single Throws Square Surgical Knots – A Preliminary Experimental & Computational Study on Knot Integrity","authors":"Amery Chow, Kyrin Liong, Shujin Lee","doi":"10.11159/icbes21.118","DOIUrl":"https://doi.org/10.11159/icbes21.118","url":null,"abstract":"In this study, the objective was to compare the knot integrity and efficiency between the two most commonly utilized surgical knots – the two double throws (2DT) and three single throws (3ST) knots via experimental testing and computational modelling. A single suture material Polyglactin 910 (Vicryl; Ethicon, Inc) was selected for this study and all sutures were of a 4-0-gauge size. 12 knotted suture samples (n=12) were prepared for each of the two surgical knot configurations. A tensile testing machine a load cell of 100N was utilized. The knots were loaded via a crosshead movement rate of 1mm/s throughout the test until knot failure, either by suture rupture at the knot or knot slippage. To test knot strength, assuming slippage does not occur, 3D scaled computational models of the 2DT and 3ST knots were created in SOLIDWORKS, and exported to a finite element analysis (FEA) software ABAQUS. The sutures were subjected to increasing static forces until the yield stress within the suture was achieved. Preliminary results suggest that the 3ST knot has a higher construction time and is more vulnerable to suture rupture when it fails at a value half that of what is required in a 2DT knot, but is more resistant to knot slippage. The 2DT surgical knot, while more vulnerable to slippage, appears to possess relative acceptable strength, with its yield only initiating at a force double of what is observed in a 3ST knot. Therefore, the 2DT knot may be more appropriate in cases where efficiency and resistance to suture rupture is prioritized due to the lower construction time and its higher load at yield. Conversely, where wound dehiscence via slippage carries a high risk, the 3ST that is more resistant to slippage is encouraged, despite the additional time required to construct.","PeriodicalId":433404,"journal":{"name":"Proceedings of the 7th World Congress on Electrical Engineering and Computer Systems and Science","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116737896","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 paper presents a new object tracker algorithm based on adaptive models of the intensity probabilities of the object and its surroundings. Using the tracked object contour in the previous frame and the object path allow to estimate a narrow search area, in which contours with high object probability are combined, after masking pixels with high surrounding probabilities away. Rules about the object contour area ensures that the tracked contour doesn’t drift away between frames or spreads into the surroundings. If the tracking is lost, the contour prediction in combination with the surrounding estimation takes over, filling the gaps until the object intensity-based tracker leads the tracking again. The proposed tracker was contrasted against three of the available trackers in OpenCV (i.e. KCF, CRST and MOSSE). Their performances were evaluated on two different applications (i.e. drone tracking and part tracking in an assembly cell) based on the Intersection over Union (IoU)-metric and their processing time. The obtained results show that the proposed tracker is faster and more accurate.","PeriodicalId":433404,"journal":{"name":"Proceedings of the 7th World Congress on Electrical Engineering and Computer Systems and Science","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128864850","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 parallel algorithms widely implemented is the Parareal algorithm to solve time-dependent differential equations for various scientific applications. Parareal algorithm has shown promising speedups in achieving near real-time solutions using accelerators. However, it has been observed that the sequential predictorcorrector step of the Parareal algorithm impacts the computational performance. This paper analyses the Parareal algorithm and proposes modification to the predictor-corrector step of the Parareal algorithm to exploit data parallelism more and reduce the computation time. The modified algorithm is implemented to solve two systems of interdependent ODEs. The numerical accuracy and performance analysis of the modified algorithm is shown to be same as the original Parareal. The performance analysis of the modified algorithm on two accelerator computing architectures: Intel Xeon Phi CPU and Graphical processing units with OpenMP, OpenACC, and CUDA programming models are presented. The modified algorithm demonstrates performance improvement ranging from 1.2x-2x with respect to the original Parareal algorithm.","PeriodicalId":433404,"journal":{"name":"Proceedings of the 7th World Congress on Electrical Engineering and Computer Systems and Science","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125453414","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}

Solar data from diverse parts of the province are collected and analysed to calculate installed capacity and amount of carbon emissions reduction at those particular locations. Hosting capacity analysis is performed in selected individual sites to ensure that the current grid can accommodate bulk solar generation.

Abdelrasoul","doi":"10.11159/icbes21.117","DOIUrl":"https://doi.org/10.11159/icbes21.117","url":null,"abstract":"Extended Abstract End stage renal disease (ESRD) affects ~10% of the world’s population. Hemodialysis (HD) is a life-sustaining extracorporeal blood purifying method for patients with ESRD or kidney failure. This membrane-based therapy is associated with acute side effects, life-threatening chronic conditions, and unacceptably high morbidity and mortality rates. Due to the lack of endothelium functionality of the polymeric surfaces of HD membranes, their interaction with human serum proteins induces an inflammatory response and leads to numerous long-term clinical consequences that are in part determined by the degree of membrane biocompatibility[1]. Blood–membrane interactions trigger a multifaceted series of events of protein adsorption, in addition to the activation blood cells such as leukocytes, platelets, and red blood cells (RBCs) or indirectly activate them through a pathway that activates the complement system or coagulation factors [2,3]. Therefore, protein adsorption provokes a series of biochemical reactions that can lead to serious longand short-term side effects in HD patients [4]. In addition, the attachment of human serum proteins on membrane surface would significantly reduce uremic toxins clearance efficiency, especially protein bound uremic toxins and middle molecules. Membrane characteristics such as chemical composition, hydrophilicity, surface roughness, pore size and binding affinity influence the interactions and the attachments between human serum proteins and HD membranes hence they can impact the inflammatory response experienced by HD patients. This study highlighted an innovative investigation on the common HD membrane morphology available in Canadian hospitals, and its affinity for human serum protein attachment. Synchrotron based X-ray imaging techniques available at the Biomedical Imaging and Therapy (BMIT) beamline at the Canadian Light Source (CLS) has answered key questions of HD membrane morphology layer-by-layer and human serum protein transport in membrane channels. This study will highlight the proof that Synchrotron imaging techniques are effective for membrane characterization and protein deposition assessment through both qualitative and quantitative analyses.","PeriodicalId":433404,"journal":{"name":"Proceedings of the 7th World Congress on Electrical Engineering and Computer Systems and Science","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132901462","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 aim is to measure a high level of alternative and direct currents (AC and DC) with high accuracy, or to use it as resistive loads suitable for calibrating instruments (such as impedance meters). The use of a low resistive impedance as a standard requires knowledge of its magnitude deviation from DC and its phase angle as a function of frequency. In this paper, we present a design of a low impedance (current shunt) for current measurements at 2 A up to 5 kHz. The structure of the current shunt is defined in a four terminal-pair (with BNC connectors). The relative deviation from DC is less than 0.23 % in magnitude for a current of 2 A up to 5 kHz.","PeriodicalId":433404,"journal":{"name":"Proceedings of the 7th World Congress on Electrical Engineering and Computer Systems and Science","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116926344","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}

{"title":"Sensitivity Analysis of Heart Rate Variability Analysis Algorithms","authors":"Amanda Perez-Porro, María Palacios, G. Caffarena, A. Otero, C. A. García","doi":"10.11159/icbes21.113","DOIUrl":"https://doi.org/10.11159/icbes21.113","url":null,"abstract":"Extended Abstract Heart rate variability analysis (HRV) is a non-invasive technique for the study of autonomic nervous system activity. HRV algorithms have a large number of configuration parameters, and it is not always clear how variations in some of these parameters influence the final result. This makes it difficult to choose appropriate parameter values [1], and hampers reproducibility of HRV studies [2]. We have carried out a sensitivity analysis of HRV algorithms to gain a better understanding of how changes in their parameters influence their results. For this end the R package RHRV was used; with about 500 monthly downloads this may be the most used HRV tool [3]. For the sensitivity analysis of the time domain algorithms and frequency domain algorithms (both based on the Shorttime Fourier transform and Wavelet transform), the MIT-BIH Normal Sinus Rhythm Database from Physionet was used. For the sensitivity analysis of ventricular beat filtering algorithms, the MIT-BIH Arrhythmia Database was used. The analysis was initially carried out using the parameters set by default in RHRV. Then, each parameter was systematically varied, reapplying the algorithms over the entire database for each variation of each parameter. The results obtained for each recording were stored in csv files for subsequent analysis. Shapiro-Wilks test ruled out the normality of the results in all cases. Friedman nonparametric test was used to assess the significance of the differences in the results. When statistically significant differences were found, the specific parameter variations that presented significant differences were found with the Post-Hoc Conover test. This permits identifying from what amount of variation of a parameter the changes are significant. Using this methodology, we have been able to identify the parameters for which even small variations produce statistically significant differences in the results of some HRV algorithm. For example, variations as small as 2% in the length of the time window used produced statistically significant differences in the time-domain index SDNN, although variations in the time window did not produce significant differences in the spectral power of the VLF, LF, and HF frequency bands.","PeriodicalId":433404,"journal":{"name":"Proceedings of the 7th World Congress on Electrical Engineering and Computer Systems and Science","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122039453","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}
