Discrete-time output feedback sliding-mode control design for uncertain systems using linear matrix inequalities [PDF]

open access: yes, 2011
An output feedback-based sliding-mode control design methodology for discrete-time systems is considered in this article. In previous work, it has been shown that by identifying a minimal set of current and past outputs, an augmented system can be ...

Numerical Simulation of Bearing Capacity Relationship Between Tile Surface Annular Groove and Thrust Surface

open access: yesJixie chuandong, 2021
In order to study the advantages of the annular groove of the tile surface on the bearing performance of the thrust sliding bearing,based on the theory of computational fluid dynamics (CFD),the oil film analysis model of the inclined plane thrust sliding

Slit-Slide-Sew Bijections for Bipartite and Quasibipartite Plane Maps [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2020
We unify and extend previous bijections on plane quadrangulations to bipartite and quasibipartite plane maps. Starting from a bipartite plane map with a distinguished edge and two distinguished corners (in the same face or in two different faces), we build a new plane map with a distinguished vertex and two distinguished half-edges directed toward the ...

Study of the Backscatter Radiation Pattern of a Quadrupole Antenna with a High-Impedance Ground Plane of Large Electrical Sizes

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2021
Introduction. The multipath resistance of GNSS antennas is largely determined by the gain slope of the amplitude radiation pattern at sliding angles (angles close to the horizon).

Improvement of revised density method for stability analysis of rigid-pile composite foundation under flexible loads

open access: yesYantu gongcheng xuebao, 2017
The revised density method is improved based on analysis of interactions between ground soil, fill and piles in flow sliding. The density of fill outside the center of sliding surface needn’t be revised.

Spectral roughness of glaciated bedrock geomorphic surfaces: Implications for glacier sliding [PDF]

open access: yes, 2000
A microroughness meter (MRM) was used to measure the high-frequency roughness of a number of geomorphic surfaces in the forefield of Glacier de Tsanfleuron, Switzerland.

Stick, partial slip and sliding in the plane strain micro contact of two elastic bodies [PDF]

open access: yesRoyal Society Open Science, 2014
The plane strain problem of a curved elastic body pressed against an elastic half-space is considered. The effect of adhesion is included through the use of surface energy in a manner similar to the well-known JKR theory for spherical contacts.

An Improved S-Plane Controller for High-Speed Multi-Purpose AUVs with Situational Static Loads

open access: yesJournal of Marine Science and Engineering, 2023
The classic S-plane control method combines PD structure with fuzzy control theory, with the advantages of a simple control structure and fewer parameters to be adjusted.

Pseudo Sliding Plane in Super-Thick Soil Materials Deposit at Ngasinan Deep Landslide Area

open access: yesRevista Brasileira de Geomorfologia
The research focuses on analyzing landslides within an area abundant in varying sizes of these occurrences. These landslides happen in consistently loose, deep volcanic sediment, referred to as soil material, over 10 meters thick.
