Using first-principles calculations, we investigate the chemisorption of H, N, and P atoms on a graphene substrate with or without Stone–Thrower–Wales (STW) defects. Energetically, all three atoms are preferred to adsorb onto the defect sites by an energy difference of 0.683–2.143 eV. In both the intrinsic and defected graphene, H atom adsorbs on top of a C atom, while N and P atoms adsorb at t...

This paper presents the results of a study of the peculiarities of subsurface longitudinal (head) waves (SLW) and transverse waves (STW) propagation in solids with wavequide surface of different geometry. Studying an acoustical path of SLW propagation along axis of metallic cylindrical solid of radius R we established, that dependence of pulse amplitude vs. distance r can be approximated by fun...

OBJECTIVES The present study examines the utility of three measures of premorbid intellectual functioning in closed head injury, the National adult reading test (NART), the Cambridge contextual reading test (CCRT), and the spot the word test (STW). METHODS In the first experiment, a group of 25 patients with closed head injury were compared with 50 healthy controls and 20 orthopaedic trauma c...

This paper focuses on observer based fault reconstruction for a class of nonlinear uncertain systems with Lipschitz nonlinearities. An adaptive-gain Super-Twisting (STW) observer is developed for observing the system states, where the adaptive law compensates the uncertainty in parameters. The inherent equivalent output error injection feature of STW algorithm is then used to reconstruct the fa...

The nanoscale structure of shock waves in high strength AlN ceramics is studied using molecular-dynamics simulations. Impacts using four independent crystallographic directions, with particle velocities in the range 0.8–4.0 km/s, reveal the generation of a welldefined two-wave structure, consisting of an elastic precursor followed by a wurtzite-torocksalt structural transformation wave (STW). I...

We studied the diagnostic predictive power of transrectal ultrasonography (TRUS) coupled with semen volume in cases of distal seminal tract sub-obstruction. As a gold standard for diagnosis we used seminal tract washout (STW). Non-azoospermic subjects (n = 112) were submitted to transrectal ultrasonography because of suspected excretory infertility or other andrological pathologies, before perf...

In this paper, the problem of integration and scheduling automated guided vehicles (AGVs) inspection machines in medical sample-testing laboratories is addressed with objective minimizing maximum turnaround time (TAT). A genetic algorithm (GA) a sliding window (STW) heuristic (GA-STW) proposed for studied while incorporating vehicle assignment (VAA) decoding operations. mathematical model AGV m...
