Motion of cranes of bridge type simulation in the MS Excel environment [PDF]

open access: yes, 2014
The idle times of the crane caused by need of replacement of wheels, can have critical value for functioning of a logistic chain. In article the task about the movement of the crane with a skew with the accounting of several mutually influencing ...

Multi‐neighborhood simulated annealing for the home healthcare routing and scheduling problem

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 1, Page 38-67, January 2026.
Abstract Over time, the focus on supportive and geriatric care has shifted from being predominantly provided in institutional settings like nursing or rest homes to be delivered within the homes of the patients. Trained caregivers now provide home healthcare services by visiting patients in their own homes and carrying out specific services based on ...

Saltation under Martian Gravity and its Influence on the Global Dust Distribution

open access: yes, 2018
Dust and sand motion are a common sight on Mars. Understanding the interaction of atmosphere and Martian soil is fundamental to describe the planet's weather, climate and surface morphology.

A Two‐Stage Optimization Model for Multiple‐Crane Service Schedules Problem

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Scheduling tower crane movements is essential in a large construction site where multiple cranes are deployed. Efficient planning can avoid potential crane collisions, reduce construction duration, and save energy consumption. The multiple‐crane service schedules problem (MCSSP) is a classic combinatorial problem.

The controllability function method [PDF]

open access: yes, 2016
The paper is devoted to the control problem for the movement of an overhead crane with the use of a dynamic model in the form of "trolley - cargo" mechanical system and the driving force as a control parameter.

A Neural Network Parametrization of Volumetric Cloud Fraction Profiles Using Satellite Observations and MERRA‐2 Reanalysis Meteorological Data

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract Clouds play a crucial role in regulating the hydrologic cycle and Earth's radiative energy budget, yet they are often poorly represented in global climate models (GCMs). This study applies deep machine learning (DML) to develop a physical parameterization of volumetric cloud fraction (VCF), the fraction of a 3‐D grid volume occupied by clouds ...

How Binding Is Administrative Guidance? An Empirical Study of Guidance, Rules, and the Courts Telling Them Apart

open access: yesJournal of Empirical Legal Studies, Volume 22, Issue 4, Page 655-689, December 2025.
ABSTRACT Guidance documents are a main pillar of the modern administrative state. While federal agencies issue thousands of rules every year through notice‐and‐comment rulemaking, they issue even more guidance documents in various forms. There is, however, an ongoing and fierce dispute over agencies' ability to create binding obligations through ...

Justification of the criterion for dynamic optimization of elastic systems (ropes) of load-lifting cranes mechanisms during forward motion

open access: yesGіrnichі, budіvelnі, dorozhnі ta melіorativnі mashini, 2018
The proposed criterion for dynamically optimizing the elastic system (ropes) of load-lifting mechanisms of cranes with translational motion, which minimizes the dynamic coefficient. The laws of motion of the elements of the lifting mechanism of the crane, in which the specified criterion can be realized, is established.

Naïve Realism and the Cognitive Penetrability of Perception [PDF]

open access: yes, 2018
Perceptual experience has representational content. My argument for this claim is an inference to the best explanation. The explanandum is cognitive penetration. In cognitive penetration, perceptual experiences are either causally influenced, or else are
