Network functions and sensitivity expressions for linear networks are reviewed for networks with single unilateral or bilateral immittances and the corresponding extension to the general case of n variable immittances. The sensitivity expression is exact and suitable for the analysis of networks with either small or large variation of parameters. A method is proposed for minimizing sensitivity using the exact expression. The general linear network is studied in various aspects like changes on...

Changes in the climate system affect a building's energy consumption. Many countries have implemented building energy consumption indices to regulate the newly built buildings from excessive energy use. However, those indices were developed based on previous climate datasets and were incapable of responding to the changing climate. To stabilize the energy uses of future buildings as those under today's climate, regular updates of the evaluation index are mandatory to take climatic variations...

A technique for the use of a digital computer for simultaneous generation of feedback control system transient response and sensitivity to parameter variations is developed. The sensitivity model for a basic linear control system is a cascaded replica of the original system with the sensitivity pickoff points corresponding to the error and feedback signals of the original system. This is convenient for computer analysis with DSL/360. For systems with nonlinear elements, the sensitivity model is...

Readiness Based Sparing (RBS) models support the life cycle of any system through the optimization of stock allowance levels. Optimal RBS results are essential to maintain fleet readiness at an acceptable cost. Naval Aviation RBS Model (NAVARM) is the tool used by Naval Supply Systems Command to plan the stock allowances for embarked airwings and shore-based aircraft. In order to gain confidence in NAVARM results, it is necessary to validate some modeling assumptions that have not been tested...

Speed, payload, and range are three primary interconnected variables in preliminary ship design. One design variable cannot be maximized without sacrificing the other(s). The purpose of this work is to analyze those combinations of speed, payload, and range that would give the optimal rate of cargo delivery, or throughput, in a given scenario. A physics based mathematical model is developed to display the inter-relationship among the three primary variables. An optimization program was also...

The reference evapotranspiration (ET 0 ) has decreased over most of China under climate change over the past few decades, especially before the 1990s, which significantly affects the agricultural water requirements. In this study, the recent tendency of ET 0 over China was determined and the issues of what causes this tendency and how this tendency would affect agricultural water demand were discussed. First, we evaluate ET 0 (consisting of the aerodynamic term ET 0_a and the radiative term ET...

The geometric viewpoint identifies the choice of a correlation matrix for the simulation of cost risk with the pairwise choice of data vectors corresponding to the parameters used to obtain cost risk. The correlation coefficient is the cosine of the angle between the data vectors after translation to an origin at the mean and normalization for magnitude. Thus correlation is equivalent to expressing the data in terms of a non orthogonal basis. To understand the many resulting phenomena requires...

Mountainous regions are important sources of freshwater. Measurement of actual evapotranspiration (ET) is difficult to obtain in high mountain regions because of the harsh natural environment, and potential ET (PET) is therefore a suitable term to describe the atmospheric water demand of land surfaces under given meteorological conditions in those high elevation areas. In situ measured meteorological data were collected in 2015 and 2016 from five meteorological stations at various elevations...

Climate change impact assessment on meteorological variables involves large uncertainties as a result of incomplete knowledge on the future greenhouse gas concentrations and climate model physics, next to the inherent internal variability of the climate system. Given that the alteration in greenhouse gas concentrations is the driver for the change, one expects the impacts to be highly dependent on the considered greenhouse gas scenario (GHS). In this study, we denote this behavior as GHS...

Observation network design requires some framework for sensitivity studies. The goal is to place observations where they will reduce forecast error the most. We use uncertainty estimates from our best forecast models as an indicator of forecast error. The first step is then to find initial-state perturbations that reduce forecast uncertainty by minimizing a user-dependent norm. Adjoint models have helped meet this challenge for decades. More recently, ensemble sensitivities have emerged as a...

In addition, biomass burning is a source of chemically active gases, including carbon monoxide, nonmethane hydrocarbons, and nitric oxide.
