Estimation of a partially linear seemingly unrelated regressions model: application to a translog cost system.

Publication Type: Academic Journal

Source(s): Econometric Reviews. 2022, Vol. 41 Issue 9, p1008-1046. 39p.

Authors:

Abstract: This article studies a partially linear seemingly unrelated regressions (SUR) model to estimate a translog cost system that consists of a partially linear translog cost function and input share equations. The parametric component is estimated via a sim...

Optimal replenishment rate for inventory systems with compound Poisson demands and lost sales: a direct treatment of time-average cost.

Publication Type: Academic Journal

Source(s): Annals of Operations Research. Oct2022, Vol. 317 Issue 2, p665-691. 27p.

Abstract: Supply contracts are designed to minimize inventory costs or to hedge against undesirable events (e.g., shortages) in the face of demand or supply uncertainty. In particular, replenishment terms stipulated by supply contracts need to be optimized with ...

Elucidating the solution structure of the K-means cost function using energy landscape theory.

Publication Type: Academic Journal

Source(s): Journal of Chemical Physics. 2/7/2022, Vol. 156 Issue 5, p1-13. 13p.

Abstract: The K-means algorithm, routinely used in many scientific fields, generates clustering solutions that depend on the initial cluster coordinates. The number of solutions may be large, which can make locating the global minimum challenging. Hence, the top...

Optimal continuous production-inventory systems subject to stockout risk.

Publication Type: Academic Journal

Source(s): Annals of Operations Research. Oct2022, Vol. 317 Issue 2, p777-804. 28p.

Authors:

Abstract: This paper studies a continuous-review production-inventory system with a constant production rate and compound Poisson demands, in which the cost of the system is assessed with holding cost and stockout penalty. For any initial inventory, we derive cl...

Finite-Set Quasi-Sliding Mode Predictive Control of $ LC$ -Filtered Voltage Source Inverters.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Industrial Electronics. Dec2022, Vol. 69 Issue 12, p11968-11978. 11p.

Abstract: Three-phase voltage source inverters (VSIs) with output $ LC$ filter are preferred topologies to provide voltage and frequency support for islanded ac microgrids. This article proposes a finite-set quasi-sliding model predictive control (FS-QSMPC) sche...

Hybrid Data-Model Predictive Control for Enabling Participation of Renewables in Regulating Reserves Service.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Industrial Electronics. Nov2022, Vol. 69 Issue 11, p11262-11271. 10p.

Abstract: A long-horizon hybrid data-model predictive direct power control (HD-MPDPC) scheme is proposed. The hybrid control scheme is for grid-side power electronic converters (PEC) in grid-connected renewable energy sources (RES). Computational burden of conve...

DC-Link Voltage Constraint Strategy for DC Power Supply Film-Capacitor Drive System Based on Improved Model Predictive Control.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Industrial Electronics. Oct2022, Vol. 69 Issue 10, p9849-9859. 11p.

Abstract: DC-link voltage oscillation is a common problem that needs special attention in dc power supply film-capacitor drive systems. For this problem, an improved model predictive control method is presented in this article, which achieves system stability co...

Estimating empirical marginal adjustment cost function: a power series approach.

Publication Type: Academic Journal

Source(s): Empirical Economics. Dec2022, Vol. 63 Issue 6, p3185-3210. 26p. 10 Charts, 3 Graphs.

Abstract: Using insights obtained from Newey's (1994) series estimator and a novel restatement of the q-theory that additively separates the marginal adjustment cost term in the canonical model, I model and estimate the shape of the marginal adjustment cost func...

Robust multi‐model controllers design without impulse in switching times for non‐linear vibrations suppression of sandwich plate.

Publication Type: Academic Journal

Source(s): IET Control Theory & Applications (Wiley-Blackwell). Oct2022, Vol. 16 Issue 15, p1548-1559. 12p.

Abstract: Generally multi‐model controllers design has three stages: Decomposition of complicated non‐linear systems into local linear models, designing the local controllers, and composition of them in sub‐regions. In the present paper an algorithm is proposed ...

Decomposition strategy aimed at minimizing power consumption.

Publication Type: Conference

Source(s): AIP Conference Proceedings. 2022, Vol. 2611 Issue 1, p1-5. 5p.

Abstract: The article presents a new strategy of function decomposition, which is aimed at reducing the dynamic power consumption of the obtained logic structures. The essence of this strategy consists in finding decompositions that minimize the number of LUT bl...
