Appexdix I: Channeling Characteristics

1972
This method is used for determining the channeling characteristics of lubricants at low temperature. It consists of storing the sample for 18 hours at the temperature required by the specification, cutting a channel in the lubricant with a metal strip, and determining whether the lubricant flows together to cover the bottom of the container within 10 ...

The analyses of channel characteristics in spatial vector channel

International Conference on Communication Technology Proceedings, 2003. ICCT 2003., 2004
Spatial vector channel is an important part of smart antenna system that has attracted wide interest in the world. However, some important characteristics of the spatial vector channel, such as joint pdf of DOA and TOA, power delay spectrum and power angle spectrum, have not clearly been studied. In this paper, we first give the theoretical analyses of

Streamflow Characteristics from Channel Size

Journal of the Hydraulics Division, 1978
Flood-peak-frequency characteristics and mean flows of ungaged streams can be estimated from field measurements of channel width using relation based on data at gaged sites. Such relations have been developed by many investigators and are shown to be in good agreement. The technique, an engineering application of research in channel morphology, is most

Calcium channel characteristics conferred on the sodium channel by single mutations

Nature, 1992
The sodium channel, one of the family of structurally homologous voltage-gated ion channels, differs from other members, such as the calcium and the potassium channels, in its high selectivity for Na+. This selectivity presumably reflects a distinct structure of its ion-conducting pore.

UWB channel sounding and channel characteristics in rectangular metal cavity

IEEE SoutheastCon 2008, 2008
This paper first describes channel sounding for ultra-wideband (UWB) channel in rectangular metal cavity. According to the measurement results, different UWB channel characteristics in such an environment are analyzed and compared with the channel characteristics of other environments such as hallway and office environments.

Seepage Characteristics of Stable Channels

Journal of the Irrigation and Drainage Division, 1977
A channel in which no erosion occurs at a given design discharge is called a stable channel. Such channels are required to transport sediment-free water. The maximum bed shear stress does not exceed the critical shear stress at any place on the surface of the channel.

Channel Characteristics in a Meandering Tidal Channel: Crooked River, Florida

Geografiska Annaler: Series A, Physical Geography, 1971
Crooked River, Florida, is a double-mouthed meandering tidal channel with an axial length of some 24 km (15 mi) and a mean sinuosity of 1.7, working in sediments derived from old beach systems but with contact in places with bedrock of Tertiary limestone. At some points it is subject to recharge from karstic risers.

Analysis of Channel Characteristic for Body Channel Communication Transceiver Design

2019
In this paper, body channel communication and its channel characteristic are investigated through measurement. Previously, the body channel communication has limitation in channel bandwidth due to its fluctuation. To verify orientation, 4 independent systemic factors are under test; (1) the size of the signal electrode attaching on the skin, (2) the ...

Studies on channel models and channel characteristics for mobile broadcasting

2008 IEEE International Symposium on Broadband Multimedia Systems and Broadcasting, 2008
This paper presents a comparison of laboratory measurements and field trials in two networks and three different use cases for mobile TV. The channel models for pedestrian outdoor, vehicular urban and motorway rural are compared to the conventional 6-tap typical urban (TU6) channel model and to corresponding field measurements.
