In this work, a new framework for breast cancer image segmentation and classification is proposed. Different models including InceptionV3, DenseNet121, ResNet50, VGG16 MobileNetV2 models, are applied to classify Mammographic Image Analysis Society (MIAS), Digital Database Screening Mammography (DDSM) the Curated Breast Imaging Subset of DDSM (CBIS-DDSM) into benign malignant. Moreover, trained modified U-Net model utilized segment area from mammogram images. This method will aid as...
Recently, biometric systems are extensively and commonly utilized for authentication verification applications. The security issue the dependence on a specific process main challenges confronted in systems. comes due to exploitation of original biometrics stored servers. Therefore, if any attacks have been introduced biometrics, they will be missed indefinitely. Consequently, must secured through maintaining storing these templates away from their So, there is need designing cancelable...
This work reports the development of an ultra-high capacity Nyquist-wavelength division multiplexing (WDM) superchannel based free space optics (FSO) transmission link. In proposed link, 32 independent wavelength channels are multiplexed, each carrying 200 Gbps dual polarization-quadrature phase shift keying (DP-QPSK) data with 60 GHz channel spacing yield net rate 6.4 Tbps spectral efficiency 3.33 bits/s/Hz. The performance FSO link has been numerically investigated under influence dynamic...
Abstract As detection of cancer and diabetes diseases has captured a great attention in the field biosensing, many ways were introduced to detect these with high accuracy. This paper presents novel use zinc selenide (ZnSe) semiconductor material enhance sensitivity conventional Ag-based surface plasmon resonance biosensor. The proposed sensor structure is simple (BK7 prism/Ag/ZnSe), cost-effective, easy design fabricate. tested different cancerous cells human blood, showing an excellent 359...
Abstract This paper introduces a novel underwater (UW) optical communication system that utilizes code division multiple access transmission technique using the permutation vector code. Three scenarios of water are considered, pure sea (PS), clear ocean (CL), and coastal (CO). The performance is evaluated analytically in terms bit error rate (BER), received power, signal to noise ratio for different UW links data rates. results show shortest range achieved case CO, achieving highest...
In the fireworks industry (FI), many accidents and explosions frequently happen due to human error (HE). Human factors (HFs) always play a dynamic role in incidence of workplace environments. Preventing HE is main challenge for safety precautions FI. Clarifying relationship between HFs can help identifying correlation unsafe behaviors influential hazardous chemical warehouse accidents. This paper aims investigate impact that contribute HE, which has caused FI disasters, explosions, incidents...
Distributed Power Generation and Energy Storage Systems (DPG-ESSs) are crucial to securing a local energy source. Both entities could enhance the operation of Smart Grids (SGs) by reducing Loss (PL), maintaining voltage profile, increasing Renewable (RE) as clean alternative fossil fuel. However, determining optimum size location different methodologies DPG-ESS in SG is essential obtaining most benefits avoiding any negative impacts such Quality (QoP) fluctuation issues. This paper’s goal...
Car manufacturers around the globe are in a race to design and build driverless cars. The concept of is also being applied any moving vehicle such as wheelchairs, golf cars, tourism carts recreational parks, etc. To achieve this ambition, vehicles must be able drive safely on streets stay within required lanes, sense objects, obstacles, read traffic signs that permanent even temporary signs. It will completely integrated system Internet Things (IoT), Global Positioning System (GPS), Machine...
A bstract Precision measurements of electron reconstruction, identification, and isolation efficiencies photon identification are presented. They use the full Run 2 data sample collected by ATLAS experiment in pp collisions at a centre-of-mass energy 13 TeV during years 2015–2018, corresponding to an integrated luminosity 139 fb − 1 . The measured have uncertainties that around 30%–50% smaller than previous results due improved methodology inclusion more data. better pile-up subtraction...
Background Admission neutrophil-lymphocyte ratio (NLR) is significantly correlated to clinical outcomes in acute ischemic stroke (AIS). We investigated follow-up NLR and temporal changes after endovascular thrombectomy (EVT) with respect successful revascularization, outcomes, symptomatic intracranial hemorrhage (sICH) mortality. Methods Retrospective analysis of EVT for anterior circulation emergent LVO was performed both admission (NLR1) 3–7 day (NLR2) laboratory data. Patient...
