Code division multiple access (CDMA) networks allow subscribers to share frequencies, so optimizing revenue involves reserving channel equivalents to each market subject to signal-tointerference constraints at the radio towers. We present a yield management model inspired by those from the airline industry to optimize revenue under uncertainty. We describe the optimality conditions and develop ...

Java-based feature extraction and pattern classification programs were developed for a Pace University CSIS Doctorate of Professional Studies student completing her thesis on long-text-input keystroke biometrics. Although the general functionality of these programs was developed for a prior DPS researcher using the SAS programming language, the current Java-based system was developed for added ...

The notion of preconception care aims to target the existing risks before pregnancy, whereby resources may be used to improve reproductive health and optimize knowledge before conceiving. The preconception period provides an opportunity to intervene earlier to optimize the health of potential mothers (and fathers) and to prevent harmful exposures from affecting the developing fetus. These inter...

This paper presents an analytical work for better design system that contributes to the reduction of fuel consumption and emission for vehicle performance. The main technological issue on engines today is to comply with emission standards with cost-effective measures in order to keep the engine price still attractive to customer. The experimental research of engine performance are time consumin...

By utilizing the real coding based accelerating genetic algorithm (RAGA) and multi-dimension DP, a method named RAGA—DP was developed to optimize irrigation system of well irrigated rice under non-sufficient irrigation condition in the Sanjiang Plain. When using DP to optimize irrigation system under non-sufficient irrigation condition, the model works well for problems such as difficulty to id...

The highly distributed nature and the load sensitivity of Service Oriented Architectures (SOA) make it very difficult to guarantee performance requirements under rapidlychanging load conditions. This paper deals with the development of service oriented autonomic systems that are capable to optimize themselves using a feedforward approach, by exploiting automatically generated performance predic...

Absorbing boundary conditions have been developed for various types of problems to truncate infinite domains in order to perform computations. But absorbing boundary conditions have a second, recent and important application: parallel computing. We show that absorbing boundary conditions are essential for a good performance of the Schwarz waveform relaxation algorithm applied to the wave equati...

Minimizing communications when mapping affine loop nests onto distributed memory parallel computers has already drawn a lot of attention. This paper focuses on the next step: as it is generally impossible to obtain a communication-free (or local) mapping, how to optimize the residual communications ? We explain how to take advantage of macro-communications such as broadcasts, scatters, gathers ...

We introduce d0 as an optimization measure for ranking problems, such as information retrieval (IR). d0 is an intuitive, differentiable measure which is somewhat correlated with standard IR measures of performance. A set of experiments is described in which the weight used to combine the results of two IR systems is chosen by optimizing d0. This technique works about as well as optimizing “exac...
