Development of microclimate in the New Holland T6.165 tractor

open access: yesResearch in Agricultural Engineering, 2023
A number of stimuli lead to what is termed "seasonal fatigue", where the only firm interconnection is the fact that this form of fatigue only occurs during a certain period of the season.

Correlation between Individual Characteristics, Work Monotony, and Mental Workload with Work Stress

open access: yesThe Indonesian Journal of Occupational Safety and Health, 2023
Introduction: Work stress is the inability of a worker to face job demands, leading to discomfort while working. Work stress can be caused by many factors, among them work monotony, excessive workload, and individual characteristics. This study's aim was

A hyperbolic universal operator commuting with a compact operator [PDF]

open access: yes, 2019
A Hilbert space operator is called universal (in the sense of Rota) if every operator on the Hilbert space is similar to a multiple of the restriction of the universal operator to one of its invariant subspaces.

Wigner functions in covariant and single-time formulations [PDF]

open access: yes, 1998
We will establish the connection between the Lorentz covariant and so-called single-time formulation for the quark Wigner operator. To this end we will discuss the initial value problem for the Wigner operator of a field theory and give a discussion of ...

Cross-Border Electricity Trading in Southeast Europe Towards an Internal European Market

open access: yesEnergies, 2020
The European Commission’s Target Model’s main objective is to integrate European electricity markets, leading to a single internal energy market and guaranteeing the instantaneous balance between electricity generation and demand. According to the target

Approximation of functions by a class of Durrmeyer–Stancu type operators which includes Euler’s beta function

open access: yesAdvances in Difference Equations, 2021
In this work, we construct the genuine Durrmeyer–Stancu type operators depending on parameter α in [ 0 , 1 ] $[0,1]$ as well as ρ > 0 $\rho >0$ and study some useful basic properties of the operators.

Making Operation-Based CRDTs Operation-Based [PDF]

open access: yesProceedings of the First Workshop on Principles and Practice of Eventual Consistency, 2014
Conflict-free Replicated Datatypes (CRDT) are usually classified as either state-based or operation-based. However, the standard definition of op-based CRDTs is very encompassing, allowing even sending the full-state, blurring the distinction. We introduce pure op-based CRDTs, that can only send operations to other replicas, drawing a clear distinction

Operator amenability of Fourier-Stieltjes algebras [PDF]

open access: yes, 2003
The notion of operator amenability was introduced by Z.-J. Ruan in 1995. He showed that a locally compact group G is amenable if and only if its Fourier algebra A(G) is operator amenable.

Rethinking Inversion in English Syntax [PDF]

open access: yesEnglish Studies at NBU, 2018
The article deals with some internal theoretical controversies in the concept and the use of the term inversion in English syntax as used in some descriptive and most pedagogical grammars of Modern English. The analysis focuses mainly on the formation of

Operator pencil passing through a given operator

open access: yes, 2013
Let $\Delta$ be a linear differential operator acting on the space of densities of a given weight $\lo$ on a manifold $M$. One can consider a pencil of operators $\hPi(\Delta)=\{\Delta_\l\}$ passing through the operator $\Delta$ such that any $\Delta_\l$
