Comparison of the single reflection and total reflection TDS techniques
Journal of Physics E: Scientific Instruments, 1984The single reflection TDS technique is compared with the total reflection technique on the basis of measurements performed on ethanediol and formamide over the frequency range of 108-1010 Hz. While confirming that single reflection TDS does indeed offer superior precision for measurements on high permittivity materials, such as water and formamide, at ...

Pressure transient analysis for long homogeneous reservoirs using TDS technique
Journal of Petroleum Science and Engineering, 2007Abstract A significant number of well pressure tests are conducted in long, narrow reservoirs with close and open extreme boundaries. It is desirable not only to appropriately identify these types of systems but also to develop an adequate and practical interpretation technique to determine their parameters and size, when possible.

Estimating Reservoir Parameters Using Thermal Transient Testing (TDS Technique)
SPE Nigeria Annual International Conference and Exhibition, 2013Abstract In the estimation of most reservoir parameters in well test, the reservoir is assumed to be isothermal which is practically not true due to the fact that there are heat sources from friction in the wellbore, work done by the drill bit and as well as thermal recovery. Although, this temperature change is small, it can serve other

A Novel Synchronization Technique Based on Kalman Filter for TD-SCDMA
2010 International Conference on Computational Intelligence and Software Engineering, 2010TD-SCDMA is the 3G mobile communication air interface specification released by International Telecommunication Union (ITU). As a TDD system, synchronization in TD-SCDMA is a key influence factor of Quality of Service (QoS). Considering that mobile communication systems work in the environment of serious interference, multipath propagation and Doppler ...

Determination of automobile paint thickness using non-contact THz-TDS technique
2015 40th International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz), 2015We use pulsed THz-TDS as a non-contact method for the measurement of thickness in automobile paint on a non-metallic substrate. We use a least square algorithm in order to fit the reflected pulses of each layer. Extracting the delay of each from the theoretical function allows us to know the thickness of each layer present in the system.

Temporal dominance of sensations (TDS) as a sensory profiling technique
2015Abstract Temporal dominance of sensations (TDS) is a relatively recent method in the sensory field aiming at collecting the sequence of the dominant sensations perceived by the subject during the tasting of a product. For instance, while tasting a piece of chocolate from intake to swallowing, the subject can successively perceive the attributes crunchy,

Surface mining for coal in the Central Appalachians contributes total dissolved solids (TDS) to headwater streams, especially below larger mines and associated valley fills. The objective of this study was to characterize the geochemical properties of a range of surface soils and associated geologic strata from the Central Appalachian coalfields and to
