Proportional navigation target tracking
… is desired. Because most anti-ship missiles use proportional navigation in their guidance systems, it is best to model their motion using the proportional navigation guidance law. An unbiased narrowband filter is required because the state estimate is used to extrapolate the trajectory over the …

Generalised proportional-integral-plus control
… in the backward shift operator. This yields Proportional-Integral-Plus (PIP) controllers that are particularly easy to implement in practice, since the state variables are defined only in terms of the sampled input and output signals. The basic PIP algorithm is extended and enhanced in …

Contamination effects in a laminar proportional amplifier
… supply air on the performance of a laminar proportional amplifier were experimentally investigated. The air supply was contaminated with oil vapor and particulate matter. Characteristic gain curves were obtained after each stage of contamination for various loading conditions. Photographs …

Metrics, Models and Methodologies for Energy-Proportional Computing
… the inability of the servers to exhibit energy proportionality which diminishes the overall energy efficiency of the data center. Therefore in this dissertation, we investigate whether it is possible to achieve energy proportionality at the server- and cluster-level by efficient power and …

COPS: A Framework for Consumer Oriented Proportional-share Scheduling
… Such priority-based mechanisms cannot guarantee proportional fairness for every process. Proportional share schedulers maintain fairness among tasks based on given weight values. In both of these scheduler types, the scheduling decision is done per-process. However, system usage policies are …

Genetic Algorithms for Solving Disjoint PathProblem with Proportional Path-Costs
… for the edge-disjoint path problem with proportional path-costs in an undirected network with single source-destination pair. Edge-disjoint path problem arises in connectivity analysis, network flow problems, VLSI-design and variety of applications. The complexity of all the variants of …

Three-Dimensional, Vision-Based Proportional Navigation for UAV Collision Avoidance
… avoidance system is based on the principle of proportional navigation (Pro-Nav), which states that a collision will occur when the line-of-sight (LOS) angles to another object remain constant. According to this guidance law, monocular electro-optical devices can be implemented on Unmanned …

Application Of The Empirical Likelihood Method In Proportional Hazards Model
In survival analysis, proportional hazards model is the most commonly used and the Cox model is the most popular. These models are developed to facilitate statistical analysis frequently encountered in medical research or reliability studies. In analyzing real data sets, checking the validity of …

Extending Sample Size Calculation for the Cox Proportional Hazards Model
… used sample size formula derived under the Cox proportional hazards (PH) model may not be proper to design a survival trial with a cure fraction, since the PH model assumption may be violated. To account for a cure fraction, the PH cure model is widely used in practice, where a PH model is used …

Collision Avoidance and Navigation of UAS Using Vision-Based Proportional Navigation
… guidance laws are based on the principle of proportional navigation (Pro-Nav), which states that a UAV is on a collision course with another vehicle or object if the line-of-sight (LOS) angles to the object remain constant. The guidance laws are designed for use with monocular electro-optical …

Reframing Cox Proportional Hazards Model for Big Data and Neural Networks
… outcome. To do this, it is common to assume a proportional hazards model and fit a proportional hazards regression (or Cox regression). A log-concave objective function known as the “partial likelihood” is maximized to fit the Cox proportional hazards model. For moderate-sized datasets, an …

Hot particle dosimetry using a wall-less tissue equivalent proportional counter
… a custom fabricated wall-less tissue equivalent proportional counter and a mechanism for increasing the beta or alpha particle source to counter distance by distances equivalent to tens of micrometers of unit density tissue. Monte Carlo computational models of the experimental apparatus were also …
