Optimization of Interconnected Natural Gas and Power Systems Using Mathematical Programs with Complementarity Constraints

Mathematics
The demand for thermal power generation from natural gas has increased globally due to its cleaner burning properties compared to other fossil fuels.

Post-Newtonian approximation of teleparallel gravity coupled with a scalar field

Nuclear Physics B, 2015
We use the parameterized post-Newtonian (PPN) formalism to explore the weak field approximation of teleparallel gravity non-minimally coupling to a scalar field ϕ, with arbitrary coupling function ω(ϕ) and potential V(ϕ).

Effect of Boundary Constraints in the Formulation of the Partition of Unity Method: One-dimensional Setting

Acta Polytechnica, 2004
The paper examines an effect of boundary constraints applied to the enhanced degrees of freedom of partition of unity based discontinuous elements. To highlight the present issue the problem is studied in a one-dimensional setting.

Decentralized controller design with asymmetric input constraints for unknown unmatched interconnected systems

工程科学学报
In this paper, we explore the decentralized control problem through the lens of adaptive dynamic programming for continuous-time nonlinear systems, particularly those with unknown mismatched interconnections and asymmetric input constraints.

Approximating Scheduling Machines with Capacity Constraints

, 2009
In the Scheduling Machines with Capacity Constraints problem, we are given k identical machines, each of which can process at most m_i jobs. M jobs are also given, where job j has a non-negative processing time length t_j >= 0. The task is to find a schedule such that the makespan is minimized and the capacity constraints are met.

On uniform approximation with interpolatory constraints

Journal of Mathematical Analysis and Applications, 1968
In this work we extend and continue the study of S. Paszkowski ([I], [Z]) who considered the relation between polynomials of best approximation and interpolating polynomials. More precisely, he studied the problem of approximating a given continuous function on an interval [a, b] by elements of an n-dimensional Haar subspace, which were also required ...

Polynomial Approximation on Unbounded Subsets and the Markov Moment Problem

International Journal of Analysis and Applications, 2013
We start this review paper by recalling some known and relatively recent results in polynomial approximation on unbounded subsets. These results allow approximation of nonnegative continuous functions with compact support contained in the first quadrant ...

Constrained Nonlinear Control of Semi-Active Hydro-Pneumatic Suspension System

Computation
Aiming at the characteristics of limited actuation capability of the semi-active control system and strong nonlinearity of the hydro-pneumatic suspension, a constrained nonlinear control strategy of a semi-active hydro-pneumatic suspension system is ...

The uniqueness of the best $L_1$-approximant of continuous Banach-valued functions under interpolatory constraints

Researches in Mathematics
We consider the best $L_1$-approximation with interpolatory constraints for continuous mapping of a metric compact set $Q$ into a Banach space $X$. The unicity set’s criterion is obtained.
