High-Capacity ECG Steganography with Smart Offset Coefficients

2017
The authors present an economic way to hide patient diagnosis information in electrocardiogram (ECG) signal based on smart offset coefficient. Simulations indicated that hiding capacity is larger than existing techniques while the perceived quality is good.

Mapping of field capacity and wilting coefficient in china for drought monitoring

Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005. IGARSS '05., 2005
Water is held in the soil pores by weaker capillary forces. When a soil is sufficiently wet, its capillary forces can hold no more water and the soil is at field capacity. Field capacity reflects the water holding capacity of the soil. Most agricultural crops require irrigation through the dry season, harvest, and after harvest.

Heat Capacities and Joule–Thomson Coefficients of HFC Refrigerants

International Journal of Thermophysics, 1999
In this report, we have examined the behavior of heat capacities and Joule–Thomson coefficients in low- and moderate-density regions based on recent theoretical studies of the ideal-gas heat capacity and virial coefficients of R-32, R-125, R-134a, R-143a, and R-152a.

Capacity utilization and the shift coefficient in Soviet planning

Economics of Planning, 1987
In the eighties greater emphasis has been placed on intensification of growth in the Soviet Union. Soviet planners are now confronted with the task of improving their knowledge of existing capacity and their means of control over both capacity utilization and expansion.

An Improved High-Capacity ECG Steganography with Smart Offset Coefficients

2018
In this article, we use the absolute-value-decision policy and effectively promote the SNR performance of the Yang and Wang’s scheme [9]. Besides, there is no need of using extra overhead for the intended receiver. Furthermore, the hidden message can be designed on-demand with various size.

Functional Principal Components of the Capacity Coefficient

2012
The efficiency of an information processing system across changes in workload (i.e. number of items to be processed) is particularly important in cognitive science. The capacity coefficient (Townsend & Nozawa, 1996; Townsend & Wenger 2004) is an empirical measure of workload efficiency based on estimated reaction time distributions.

Heat Capacity, Conductivity, and the Thermal Coefficient of Expansion

2018
Heat capacity depends on the initial and final states, and on the path of the transition between them. The heat capacity of the powder is approximately that of natural diamond in the 500-700K temperature range. The peculiarities of diamond film structure make it worthwhile to separate them into two conventional classes: the thin films and the thick ...

Investigations on CO2 storage capacity in saline aquifers—Part 2: Estimation of storage capacity coefficients

International Journal of Greenhouse Gas Control, 2009
Abstract Many studies on geological carbon dioxide (CO 2 ) storage capacity neglect the influence of complex coupled processes which occur during and after the injection of CO 2 . Storage capacity is often overestimated since parts of the reservoirs cannot be reached by the CO 2 plume due to gravity segregation and are thus not accessible for ...

Influence of Addendum Modification Coefficient on the Gear’s Load Capacity

2008
There are many factors that influence at the mechanical behavior of gears. The gear’s mechanical phenomenons are greatly conditioned by teeth’s profile. One of the values that is most important and influential is the addendum modification coefficient value (x1, x2).

A simple method for obtaining heat capacity coefficients of minerals

American Mineralogist
Abstract Heat capacity data are unavailable or incomplete for many minerals at geologically relevant temperatures. Despite the availability of entropy and enthalpy values in numerous thermodynamic tables (even sometimes at elevated temperatures), there remains need for extrapolation beyond, or interpolation between, temperatures.
