MIMO channel model
… been applied: the equal power allocation and the water-filling. Mean capacity of both equal power and water-filling increased as the signal to noise ratio (SNR) is increased. The difference between these two capacities is that the equal power method has no knowledge about the channel of the …

Dynamic resource allocation for cognitive radio systems
… multicarrier OFDM based CR systems. Traditional water-filling algorithm is inefficient for OFDM-CR networks due to the interaction with primary users (PU)s. We consider reliability/availability of subcarriers or primary user activity for power allocation. We model this aspect mathematically with …

Effective Resource Allocation for Non-cooperative Spectrum Sharing
… Shannon capacity utility function results in a water-filling solution. In this thesis, the suitability of the water-filling solution is evaluated when using non-Gaussian signalling first in a frequency non-selective environment to focus on the resource allocation problem and its outcomes. It is …

Application of Automated Facial Expression Analysis and Qualitative Analysis to Assess Consumer Perception and Acceptability of Beverages and Water
… consumers emotional response to dairy (n=42) and water (n=46) beverages. For dairy, unflavored milk (x=6.6±1.8) and vanilla syrup flavored milk (x=5.9±2.2) (p>0.05) were acceptably rated (1=dislike extremely; 9=like extremely) while salty flavored milk (x=2.3±1.3) was least acceptable (p<0.05). …

Capacity of Gaussian noise channels with side information and feedback
… power allocation is determined by the well-known water-filling procedure. The basic water-filling power allocation is extended to include minimal rate and / or maximal power constraints. Various imperfections in the side-information and their influence on capacity and the power allocation are …

Structural studies of nonionic lyotropic liquid crystals
… have been studied in binary mixtures with heavy water, using techniques including optical microscopy, nuclear magnetic resonance and x-ray and neutron scattering. The liquid crystalline phases have been characterized and their dimensional parameters determined. A phase diagram of C 16E06 has been …

Adaptive Coded Modulation Classification and Spectrum Sensing for Cognitive Radio Systems. Adaptive Coded Modulation Techniques for Cognitive Radio Using Kalman Filter and Interacting Multiple Model Methods
… to adjust the transmitted power, by using a water-filling (WF) technique, and constellation pattern and rate in the ACM algorithm. The AMC has also benefited from such IMM-KF integration to boost the performance against conventional parametric estimation methods such as maximum likelihood …

Machine Learning Aided Decision Making and Adaptive Stochastic Control in a Hierarchical Interactive Smart Grid
… profile is in the form of a two-dimensional water-filling solution either with flat water levels or different water levels for different customers. A trade-off strategy which attempts to balance the competing objectives (centralized and distributed) is also provided based on the Price of …

A Multifaceted Phenomenon of Hydrophobic Effects: Insights Learned from Nucleation Algorithm Based Computer Simulation Approach
… under confined environment rather than in bulk water. This association is primarily driven by energy originating from the unique situation where small (i.e., two methane molecules) and large (i.e., boundary of the hydrophobic cavity) hydrophobic units come together. For the second subject, …

Efficient radio resource management for the fifth generation slice networks
… QoS for different slice use cases, an adapted water filling algorithm, and stochastic geometry tools are employed to xxi model the global energy efficiency (GEE) of the 5G slice network. Besides, neither stochastic geometry nor a three-level hierarchical business model schemes have been …

MIMO Wireless Networks: Modeling and Optimization
… involving complex matrix operations and the water-filling algorithm. At the link layer, we devise a space-time scheduling scheme called order-based interference cancellation (OBIC) that significantly advances the existing zero-forcing beamforming (ZFBF) to handle interference in a multi-hop …

Channel Probing for an Indoor Wireless Communications Channel
The statistics of the amplitude, time and angle of arrival of multipaths in an indoor environment are all necessary components of multipath models used to simulate the performance of spatial diversity in receive antenna configurations. The model presented by Saleh and Valenzuela, was added to by …
