The challenges that arise in the process of developing robotic means of locomotion controlled by people with disabilities are examined in this paper. In addition, the methods of managing modern wheelchairs are analyzed. In order to prevent the occurrence of critical situations in the process of...

Electronic contact lenses (ECL) are a high-tech solution for diagnosing, including early, both ophthalmic and systemic diseases. The authors of the article propose the implementation of 3P medicine approaches by integrating electrodes and circuits into the ECL to realize bioelectrical impedance...

The possibility of using textural features for the differential diagnosis of primary extra-axial tumors on the basis of two-dimensional digital magnetic resonance (MR) images is being investigated. Histogram and correlation characteristics, as well as features based on run lengths, were considered...

With the use of tetracycline in childhood, as well as with intrauterine or ectopic exposure before teething through the gums during mineralization or calcification of the teeth, the antibiotic binds to calcium ions in the teeth. This results in permanent staining of the teeth. In dentistry, the...

Up to date, adaptive beamforming technologies have been successfully introduced to medical ultrasound imaging, resulting in a considerable improvement in imaging quality versus non-adaptive delay-and-sum beamformers. Minimum Variance (MV) adaptive beamforming improved resolution rather than...

In recent years, the use of Raman and surface enhanced Raman spectroscopy for disease detection has grown. The motives for their increased use have commonly been attributed to their well-known benefits, such as the creation of narrow spectral bands that are characteristic of the molecular...

This paper introduces a novel approach to blood cell classification using convolutional neural networks (CNNs). Our emphasis lies in methodological insights derived from comparative analyses across various CNN architectures, implemented in Python with PyTorch such as ResNet152V2, Xception,...

This study explores the use of spatially-resolved diffuse reflectance spectroscopy for non-invasive method for measuring subcutaneous fat layer thickness. We investigated the relationship between spectroscopic measurements and hypodermis thickness, particularly focusing on lipid absorption...

Brain-computer interface (BCI) was first only thought of as a control channel for end users with simple disabilities, like those locked in a room. Nevertheless, the spectrum of BCI applications has significantly increased due to the multidisciplinary advancements made over the past ten years....

In recent years, the research on deep Convolutional Neural Networks (CNNs) has led to remarkable advancements in image categorization and segmentation. This paper presents a new Computer-Aided Detection (CAD) system utilizing convolutional neural networks and Computed Tomography (CT) image...

The paper is devoted to the identification of skin tumors and interpretation of their component composition based on multidimensional analysis of Raman scattering spectral data and dermoscopic images. The dataset contains 65 samples of malignant melanomas, 107 seborrheic keratoses, and 166 nevi....

The purpose of this study was to measure blood levels in quail meat with a cellphone camera using a spectrophotometer as a standard. Samples were obtained from 9 pieces of quail meat cut by hanging, 9 pieces of quail meat cut without hanging, 9 pieces of quail carcass dead for 4 h, and 9 pieces of...
