On a computer implementation of the block Gauss-Seidel method for normal systems of equations

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2016
This article focuses on the modification of the block option Gauss-Seidel method for normal systems of equations, which is a sufficiently effective method of solving generally overdetermined, systems of linear algebraic equations of high dimensionality ...

Performance improvement of discrete‐time linear‐quadratic regulators applied to uncertain linear systems using the Tikhonov regularization method

Asian Journal of Control, EarlyView.
Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

Fiber Bragg Grating Force Sensors for Minimally Invasive Surgery: State of the Art, Challenges, and Opportunities

SmartBot, EarlyView.
This article reviews the application of fiber Bragg grating (FBG) technology for precise force sensing in minimally invasive surgery. It outlines the fundamental working principles and algorithms used to interpret sensor data. The text surveys clinical applications across various medical fields, such as ophthalmology and vascular intervention (Table of

Calibration of Phased-Array High-Frequency Radar on an Anchored Floating Platform

Remote Sensing, 2022
Prior studies have highlighted the importance of calibrating receiver antennas in target direction-of-arrival (DOA) estimation and surface current measurement for high-frequency (HF) radar systems.

Kinematics‐based model for shear capacity assessment of unreinforced interior beam–column joints

Structural Concrete, EarlyView.
Abstract This study presents a kinematics‐based model for assessing the shear strength of reinforced concrete interior beam–column joints without transverse reinforcement. The proposed framework is built on first principles—kinematics, equilibrium, and constitutive relations—and explicitly models discrete cracks by introducing kinematic parameters such

Global properties of a class of overdetermined systems

Journal of Functional Analysis, 2003
The authors study a class of overdetermined systems of two complex linear differential equations on the three-dimensional real torus with one unknown function described as follows. Let \(\varphi=a\,dt + b\,ds\) be a real analytic closed differential \(1\)-form on the two-dimensional torus with periodic coordinates \((t,s)\) and let \(\Pi\) be the ...

The company you keep: becoming one(self) in an Indonesian convent En bonne compagnie : devenir (quelqu’)un dans un couvent indonésien Pergaulan dalam biara di Indonesia: sebuah proses pembentukan diri*

Journal of the Royal Anthropological Institute, EarlyView.
This article investigates companionate processes of self‐making in a religious community of Catholic nuns in eastern Indonesia. I argue that the sociality of the convent establishes a unique context for understanding the effects of one's company on processes of self‐becoming.

Mathematical Problems in Creating Large Astronomical Catalogs

Open Astronomy, 2016
The next stage after performing observations and their primary reduction is to transform the set of observations into a catalog. To this end, objects that are irrelevant to the catalog should be excluded from observations and gross errors should be ...

Islam at the monastery: on infinity as subtractive truth L'islam au monastère : de l'infini comme vérité soustractive

Journal of the Royal Anthropological Institute, EarlyView.
Based on ethnographic research at Rūm Orthodox Christian monasteries in Lebanon, the article studies scenes of Islam at the monastery as they intersect with anxious public debates on, and anthropological theorizations of, sectarianism and ‘Muslim–Christian’ relations in the Mashriq.

THE ANALOG CITY: Maintaining Everyday Life Through Repair and Jugaad

International Journal of Urban and Regional Research, EarlyView.
Abstract Urban scholarship consistently discusses improvisation and heterogeneity as central to urban life in the global South. In this article, I bring together scholarship on urban improvisation and the digital world of smart cities to understand the city as analog.
