Celiac disease (CD) is a lifelong chronic autoimmune systemic that primarily affects the small bowel of genetically susceptible individuals. The diagnostics adult CD currently rely on specific serology and histological assessment duodenal mucosa samples taken by upper digestive endoscopy. Because several pitfalls associated with biopsy sampling histopathology, considering pediatric no-biopsy diagnostic criteria, biopsy-avoiding strategy has been proposed for diagnosis also. Several...

To protect the personnel of intervention units operating in high-risk areas, it is necessary to introduce (autonomous/semi-autonomous) robotic systems. Previous studies have shown that systems should be as versatile possible. Here, we focused on idea a system composed two vectors: carrier vector and an operational vector. The proposed particularly relates A simple analytical model was developed enable entire assembly autonomous. validate analytical-numerical regarding kinematics dynamics...

One of the problems that we face today is illegal use drones. Monitoring RF transmissions has proved to be a reliable technique for detecting and identifying such devices. Although there are some solutions on market detection jamming, they not always successful. The aim this paper analyze typical communications used by drone manufacturers, which usually implement their own algorithms, propose more robust solution would consider range characteristics these protocols have. A wide-band energy...

This paper proposes an automatic method of detection facial features - eyes and mouth, based on color the symmetry map. The improvement quality image application correction techniques, such as re-escalation image, ellipsoidal vignetting or related processing lead to a rate up 82.21%, compared 56.18% value that was obtained initially.

Abstract The paper proposes an algorithm for applying the perspective correction of images containing human faces. Based on coordinates two eyes, center mouth and a point line mouth, one can estimate angle inclination face. After correction, area corresponding to face be used by recognition based aspect in order improve good rate.

Analysis of unintended compromising emissions from Video Display Units (VDUs) is an important topic in research communities. This paper examines the feasibility recovering information displayed on monitor reconstructed video frames. The study holds particular significance for our understanding security vulnerabilities associated with electromagnetic radiation digital displays. Considering amount noise that TEMPEST frames have, work this focuses two different approaches to de-noising images...
