Pressure transient analysis for long homogeneous reservoirs using TDS technique

Journal of Petroleum Science and Engineering, 2007
Abstract 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.

Comparison of the single reflection and total reflection TDS techniques

Journal of Physics E: Scientific Instruments, 1984
The 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 ...

Temporal dominance of sensations (TDS) as a sensory profiling technique

, 2014
Abstract 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,

Application of TDS technique to developed reservoirs

Journal of Petroleum Science and Engineering, 2007
Abstract Well test interpretation methods for a single well in infinite reservoirs may not be suitable for those wells when their pressure is affected by other wells operating in the same reservoir. This effect becomes more significant as both the flow rate and the test duration increase.

On low-complexity joint-detection techniques for TD-CDMA

IEEE Transactions on Wireless Communications, 2005
This paper is focused on low-complexity joint-detection (JD) algorithms, where the computational complexity is reduced using banks of discrete Fourier transformations. Mainly, we have developed a fast hybrid zero-forcing block decision-feedback equalizer (H-ZF-BDFE) combining the Fourier-based JD scheme (IEEE J. Sel. Areas Commun., vol. 19, p.

Performance of call admission control techniques for TD-CDMA systems

2003 IEEE 58th Vehicular Technology Conference. VTC 2003-Fall (IEEE Cat. No.03CH37484), 2003
TD-CDMA (time division code division multiple access) systems adopt a hybrid access scheme. Using different spreading codes several radio carriers are defined on the same bandwidth. On each carrier a time frame is used to multiplex different channels. So a channel is defined by a code and a time slot.

Energy-efficient power amplifier techniques for TD-SCDMA and TD-LTE multi-standard wireless communications

2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
An energy-efficient concurrent dual-band Doherty power amplifier (PA) and its related digital predistortion (DPD) for TD-SCDMA and TD-LTE multi-standard wireless communications are investigated in this paper. Due to the proposed inter-modulation tuning technique, the PA efficiency and output power in concurrent operation mode are improved significantly.

PARR reduction of TD-SCDMA with Joint Transmission technique

2010 10th International Symposium on Communications and Information Technologies, 2010
Joint Detection (JD) technique is used to reduce intersymbol interference (ISI) and multiple access interference (MAI) in current downlink (DL) of Time-Division Synchronous Code-Division-Multiple-Access (TD-SCDMA). However, the technique requires significant calculation and channel estimator in mobile station (MS), causing complexity in MS.
