Approximate Riemann Solvers, Parameter Vectors, and Difference Schemes
- J. COMP. PHYS
, 1981
"... Several numerical schemes for the solution of hyperbolic conservation laws are based on exploiting the information obtained by considering a sequence of Riemann problems. It is argued that in existing schemes much of this information is degraded, and that only certain features of the exact solution ..."

are worth striving for. It is shown that these features can be obtained by constructing a matrix with a certain “Property U.” Matrices having this property are exhibited for the equations of steady and unsteady gasdynamics. In order to construct them, it is found helpful to introduce “parameter vectors
Probabilistic Roadmaps for Path Planning in High-Dimensional Configuration Spaces
- IEEE INTERNATIONAL CONFERENCE ON ROBOTICS AND AUTOMATION
, 1996
"... A new motion planning method for robots in static workspaces is presented. This method proceeds in two phases: a learning phase and a query phase. In the learning phase, a probabilistic roadmap is constructed and stored as a graph whose nodes correspond to collision-free configurations and whose edg ..."

nodes. The method is general and easy to implement. It can be applied to virtually any type of holonomic robot. It requires selecting certain parameters (e.g., the duration of the learning phase) whose values depend on the scene, that is the robot and its workspace. But these values turn out
Learnability and the Vapnik-Chervonenkis dimension
, 1989
"... Valiant’s learnability model is extended to learning classes of concepts defined by regions in Euclidean space E”. The methods in this paper lead to a unified treatment of some of Valiant’s results, along with previous results on distribution-free convergence of certain pattern recognition algorith ..."

Games with Incomplete Information Played by 'Bayesian' Players, I-III
- MANAGEMENT SCIENCE
, 1967
"... The paper develops a new theory for the analysis of games with incomplete information where the players are uncertain about some important parameters of the game situation, such as the payoff functions, the strategies available to various players, the information other players have about the game, e ..."

probability distributions derived from a certain "basic probability distribution " over the parameters unknown to the various players But later the theory is extended also to cases where the different players' subjective probability distributions fail to satisfy this consistency assumption
Lexical-Functional Grammar: A Formal System for Grammatical Representation
- IN: FORMAL ISSUES IN LEXICAL-FUNCTIONAL GRAMMAR
, 1995
"... In learning their native language, children develop a remarkable set of capabilities. They acquire knowledge and skills that enable them to produce and comprehend an indefinite number of novel utterances, and to make quite subtle judgments about certain of their properties. The major goal of psychol ..."

Variable Selection via Nonconcave Penalized Likelihood and its Oracle Properties
, 2001
"... Variable selection is fundamental to high-dimensional statistical modeling, including nonparametric regression. Many approaches in use are stepwise selection procedures, which can be computationally expensive and ignore stochastic errors in the variable selection process. In this article, penalized ..."

likelihood approaches are proposed to handle these kinds of problems. The proposed methods select variables and estimate coefficients simultaneously. Hence they enable us to construct confidence intervals for estimated parameters. The proposed approaches are distinguished from others in that the penalty
TIGHT CLOSURE TEST EXPONENTS FOR CERTAIN PARAMETER IDEALS
, 2005
"... Abstract. This paper is concerned with the tight closure of an ideal a in a commutative Noetherian ring R of prime characteristic p. The formal definition requires, on the face of things, an infinite number of checks to determine whether or not an element of R belongs to the tight closure of a. The ..."

exponents exist if and only if tight closure commutes with localization’. The main purpose of this paper is to provide a short direct proof that test exponents exist for parameter ideals in a reduced excellent equidimensional local ring of characteristic p. Throughout the paper, R will denote a commutative
Effect of dilatrend and metoprolol on certain parameters of hemocoagulation system
"... We were aimed to study effect of the third generation β-blockers- metoprolol and dilatrend (in vitro) on the following parameters of hemocoagulation system in patients with ischemic heart disease: ATIII, time of blood coagulation, time of partial thromboplastin, time of recalcification, prothrombin ..."

Testing for Common Trends
- Journal of the American Statistical Association
, 1988
"... Cointegrated multiple time series share at least one common trend. Two tests are developed for the number of common stochastic trends (i.e., for the order of cointegration) in a multiple time series with and without drift. Both tests involve the roots of the ordinary least squares coefficient matrix ..."

similar. The firstest (qf) is developed under the assumption that certain components of the process have a finite-order vector autoregressive (VAR) representation, and the nuisance parameters are handled by estimating this VAR. The second test (q,) entails computing the eigenvalues of a corrected sample
Gaussian interference channel capacity to within one bit
- 5534–5562, 2008. EURASIP Journal on Advances in Signal Processing
"... Abstract—The capacity of the two-user Gaussian interference channel has been open for 30 years. The understanding on this problem has been limited. The best known achievable region is due to Han and Kobayashi but its characterization is very complicated. It is also not known how tight the existing o ..."

Using our results, we provide a natural generalization of the point-to-point classical notion of degrees of freedom to interference
