A dedicated 4-m-high vertical wind tunnel has been designed and constructed at the University of Geneva in collaboration with the Groupe de compétence en mécanique des fluides et procédés énergétiques. With its diverging test section, the tunnel is designed to study the aero-dynamical behavior of non-spherical particles with terminal velocities between 5 and 27 ms(-1). A particle tracking veloc...

Background: Health literacy is the ability of a patient to understand their medical condition. The purpose of this investigation is to determine whether patients are able to obtain an elementary understanding of the fundamental principles of carpal tunnel release and the postoperative instructions after going through the process of informed consent and being provided an additional standardized ...

Abstract In order to further explore the large deformation control technology of high ground stress soft rock tunnel, this study takes highly weathered carbonaceous shale section Muzhailing tunnel as research background, effect scheme 1 “three-step method” and 2 “pilot expansion are compared analysed by field test numerical simulation. The results show that simulation consistent with test, tren...

In this study, the design of a wind tunnel was carried out to observe airflow through an airfoil, streamlines and turbine blades. To accommodate this, in study made open return tunnel. case, circuit type will be because construction is simpler manufacturing costs are relatively cheaper compared closed type. The Wind Tunnel designed with Open CLosed (OCWT) OCWT consist fan housing, diffuser, tes...

Diagnosis of carpal tunnel syndrome is based on clinical findings and electrodiagnostic findings are used to confirm the diagnosis. On the other hand, sonography has enjoyed attention as a noninvasive method for diagnosis of carpal tunnel syndrome. 76 hands of patients in whom the diagnosis of carpal tunnel syndrome was confirmed and 80 hands in the control group were enrolled in the study. In ...

With the rapid construction of metro tunnels in many metropolises, a fast and convenient solution to capture tunnel deformation is desired by civil engineers. This contribution reports an automatic and wireless tunnel deformation monitoring system using ultrasonic transducers. A processing algorithm of the redundant ultrasonic information (RUI) approach is proposed to improve measurement accura...
