Optimization of Control and Parameters in Systems with Phase Constraints

Журнал вычислительной математики и математической физики, 2023
For an optimal control problem with constraints on phase coordinates, an iterative method for finding a numerical solution is considered, based on reduction to a finite-dimensional problem and applying to it a sequential linearization algorithm using a modified Lagrange function.

Inferring dependency constraints on parameters for web services

Proceedings of the 22nd international conference on World Wide Web, 2013
Recently many popular websites such as Twitter and Flickr expose their data through web service APIs, enabling third-party organizations to develop client applications that provide function-alities beyond what the original websites offer. These client appli-cations should follow certain constraints in order to correctly in-teract with the web services.

COSMOLOGICAL DISTANCE MEASURE CONSTRAINTS ON THE DECELERATION PARAMETER

International Journal of Modern Physics D, 2009
Constraints on a parametrized deceleration parameter, q(a) = q0+ q1(1 - a), are investigated using cosmological observations of type Ia supernovae (SN Ia), baryon acoustic oscillations (BAOs) and cosmic microwave background (CMB) and observational Hubble data (OHD) which correspond to the cosmological distance measure.

Observational constraints on the cosmological parameters

AIP Conference Proceedings, 1995
Latest estimates of the three cosmological parameters, the density parameter, Hubble constant and the cosmological constant are discussed, in particular with regard to observational constraints on their possible values. These observational constraints include limits on the density of baryonic matter from Big Bang nucleosynthesis, estimates of mass ...

CONSTRAINTS TO DECELERATION PARAMETERS BY RECENT COSMIC OBSERVATIONS

Modern Physics Letters A, 2008
In this paper, two simple parametrized deceleration parameters [Formula: see text] and [Formula: see text] areconstrained by using the latest SNe Ia Gold dataset, observational Hubble data and their combination. It is found that the transition redshift from decelerated expansion to accelerated expansion zT and current decelerated parameter values q0 ...

Parameters, ecological constraints and exergy

Ecological Modelling, 1992
Abstract The relation between parameter choice and exergy was found for models of increasing complexity. The results show that the exergy is (very) dependent on the parameters that were examined, i.e. growth rates of phytoplankton, bacteria, two zooplankton classes, and fish. ‘Survival of the fittest’, which is represented in the model by the exergy,

VAR Processes with Parameter Constraints

1991
In Chapter 3, we have discussed estimation of the parameters of a K-dimensional stationary, stable VAR(p) process of the form $$ y_t = \nu + A_1 y_{t - 1} + \ldots + A_p y_{t - p} + u_t , $$ (5.1.1) where all the symbols have their usual meanings. In the investment/income/consumption example considered throughout Chapter 3, we found that many

Inter-parameter Constraints in Contemporary Web APIs

2017
Today’s web applications often rely on a myriad of external web APIs, communicating with them through various HTTP requests spread throughout the application. These APIs are often textually described by constraints on the inputs and outputs of their entry points. In this paper we discuss constraints in web APIs that span multiple parameters.

CONSTRAINTS ON PARAMETERS OF THE BLACK HOLE AT THE GALACTIC CENTER

2013
We consider shadows around black holes as a tool to evaluate their parameters and to find eventual signatures of extra dimensions.
