Regarding doming of AK mask, many investigations have been made so far. The mechanical design looks almost at the limit. Curvature design of the mask is a key point. The subject is discussed from the panel curvature point of view and a new panel curvature function that is advantageous for mask design is proposed

In this study, the heat transfer characteristics of flat plate collectors with circular and elliptical serpentine tubes are theoretically analyzed compared in terms m˙, Re, Nu, hfi, FR, Qu, μTh under various water flow rates standard test conditions. The results reveal that maximum correspondence to design 56% turbulent flow, minimum 47% for cross-section laminar flow. addition, it was found hi...

This paper discusses a discrete-time modeling technique where the length of time delays can be arbitrarily adjusted. The new system is called a fractional delay waveguide model (FDWM). Formerly, FDWMs have only been implemented with FIR-type fractional delay filters. We show how an FDWM can be implemented using allpass filters. We use low-order allpass filters that are maximally-flat approximat...

We show that the maximal future development of asymptotically flat spherically symmetric black hole initial data for a selfgravitating nonlinear scalar field, also called a Higgs field, contains a connected, achronal marginally trapped tube which is asymptotic to the event horizon of the black hole, provided the initial data is sufficiently small and decays like O(r− 1 2 ), and the potential fu...

Electromagnetic information leakage from computer displays was first demonstrated to the general public by van Eck in 1985. Nearby eavesdroppers can pick up compromising emanations from computer hardware with directional antennas and wideband receivers. The basic phenomenon is easily demonstrated with modified TV sets. However, to separate practically readable text shown on modern high-resoluti...

In this work, we present a non-permanent method to connect microfluidic devices. The approach uses short flexible tubes that are plugged into bottom-flat holes and ensure fast and reliable interconnections. The small available dimensions allow the tube to be directly attached to the side of planar microchips. A theoretical model to estimate the maximum applicable pressure was developed, and ver...

Multiwall Carbon Nanotubes (MWCNTs) were synthesized by Chemical Vapor Deposition (CVD). Two different procedures were used to grow MWCNT films roughly, aligned in the direction normal to the SiO2/Si(111) substrate. Inverse Photoemission Spectroscopy measurements, on these samples, show the existence of resonances which could be traced back to a flat graphene sheet. The unoccupied valence band ...

A rapid culture test has been developed and evaluated for the detection of adenovirus in ocular infections. The test requires only two days' incubation of the inoculated cell monolayers on coverslips in flat bottomed tubes followed by detection of adenovirus inclusions using immunofluorescence staining method. The sensitivity of the rapid test is found to be comparable with that of the conventi...

BACKGROUND To ensure adequate function after orthopedic tumor reconstruction, it is important to reattach the remaining soft tissue to the implant. This study aimed at obtaining mechanical properties of textile muscle-implant and muscle-bone connections in a preliminary test. METHODS Two groups of soft-tissue attachment were mechanically tested and compared: Native bone-muscle samples obtaine...

ArfGAP1, which promotes GTP hydrolysis on the small G protein Arf1 on Golgi membranes, interacts preferentially with positively curved membranes through its amphipathic lipid packing sensor (ALPS) motifs. This should influence the distribution of Arf1-GTP when flat and curved regions coexist on a continuous membrane, notably during COPI vesicle budding. To test this, we pulled tubes from giant ...
