Computational Models for the Helix Tilt Angle

Journal of Chemical Information and Computer Sciences, 2004
The concept of hydrophobic imbalance and that of hydrophobic and hydrophilic centers are used along with side chain models in the computation of helix orientation and tilt angle in or near a membrane. Rotamer statistics are used to infer typical side chain positions and chain length for each amino acid, and the results are used in fast computation of ...

Optimum Tilt Angle for Solar Collectors

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2006
A solar collector is required to absorb solar radiation and transfer the absorbed energy into a heat transfer fluid with a minimum of heat loss. In assessing the performance of a collector, it is therefore important not only to determine its ability to absorb solar radiation but also to characterize its heat losses. The ability of a collector to absorb

Omniphobic Metal Surfaces with Low Contact Angle Hysteresis and Tilt Angles

Langmuir, 2018
Various metal (Al, Ti, Fe, Ni, and Cu) surfaces with native oxide layers were rendered "omniphobic" by a simple thermal treatment of neat liquid trimethylsiloxy-terminated polymethylhydrosiloxanes (PMHSs) with a range of different molecular weights (MWs). Because of this treatment, the PMHS chains were covalently attached to the oxidized metal surfaces,

Design of Tilt Angle Measurement System

Advanced Materials Research, 2012
For the purpose of inclination measurement and monitoring, a tilt angle measurement system using a heat convection accelerometer is presented in this study. A conditioning circuit that center around the single chip processor is designed and built. Experiments were carried out to characterize the measuring system with the range of-90° to +90°.

Integrated Polarizer with Tilted Polarization Angle

Asia Communications and Photonics Conference, 2017
A polarizer with polarization angle other than 0° or 90° is proposed on silicon-on- insulator platform. The extinction ratio is larger than 20 dB and excess loss is lower than 1 dB over 100 nm wavelength range.

Optimum Tilt Angle Determine

2017
After treating extraterrestrial and terrestrial solar radiations in the previous chapters, the use of this information in treating an important question regarding the installation of fixed solar systems, namely the tilt and orientation of the solar receivers, becomes possible. There are several rules that guide designers in this field.

Guiding sleeve tilt angle in paralleling instruments

Journal of Oral Rehabilitation, 1984
SummaryTo investigate the guiding sleeve tilt angle in paralleling instruments, the diameter of guiding sleeves and drill shanks were measured for a number of instrument makes and Spirko type drill makes. Significant diameter differences between makes were found for drills as well as for sleeves.

Kinematically Excited Large Angle Tilting Actuator

Volume 4: 12th International Conference on Advanced Vehicle and Tire Technologies; 4th International Conference on Micro- and Nanosystems, 2010
We report on a novel architecture and operational principle of a large angle kinematically excited tilting micro actuator. The device transforms and amplifies small linear out-of-plane motion of a parallel-plate electrostatic transducer into a tilting motion of a plate. The device characterized by robust single layer architecture was fabricated using a

Tilting angle and water slippage over hydrophobic coatings

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2011
Hydrophobic coatings, such as octadecyltrichlorosilane or n-alkyl monolayers, enhance the slippage of liquids on solid walls. For a given alkyl chain length, the main structural parameter for homogeneous coatings is the tilt angle between coating molecules and the surface normal.

Perceptions of Tilt Angles of an Agricultural Tractor

Journal of Agromedicine, 2014
A tractor stability simulator has been developed to help study tractor operators' perceptions of angles when the simulator is tilted to the side. The simulator is a trailer-mounted tractor cab equipped with hydraulic lift that can tilt the tractor cabin up to 30 degrees.
