What Road Elements are More Important than Others for Safe Driving on Urban Roads?

open access: yesPromet (Zagreb), 2023
Road elements are increasingly digitalized to provide drivers advanced assistance especially in the emergent or adverse conditions. It is challenging and expensive to accurately digitalize all the road elements especially on the urban roads with many ...

Chain Conditions on Symmetric Elements [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
Recently Britten has proven an analog of Goldie’s theorem for the Jordan ring S S of symmetric elements in a ring with involution of characteristic not 2. In this paper we first extend Britten’s theorem to the situation where R R is an arbitrary ring and the Jordan ring is only an ample subring of the symmetric ...

Data on rare earth elements in mining environments under non-acidic conditions

open access: yesData in Brief, 2019
This article contains analytical data on Rare Earth Elements (REE) concentration in waters and solid samples (mining wastes and biominerals) collected in an abandoned mining site characterized by near-neutral conditions, and they are related with the ...

Normalization between stimulus elements in a model of Pavlovian conditioning: Showjumping on an elemental horse [PDF]

open access: yesLearning & Behavior, 2012
Harris and Livesey. Learning & Behavior, 38, 1-26, (2010) described an elemental model of associative learning that implements a simple learning rule that produces results equivalent to those proposed by Rescorla and Wagner (1972), and additionally modifies in "real time" the strength of the associative connections between elements.

On the continuity of the magnetizing current density in 3-D magnetic field analysis with edge element [PDF]

open access: yes, 1995
The effects of the continuity of the magnetizing current density on the convergence of the incomplete Cholesky conjugate gradient method and the accuracy of the calculated flux densities are investigated by imposing different continuity conditions for ...

Influence of seasonal conditions on the failure rate parameter of elements of the KAMAZ-43118 engine power supply system

open access: yesИнтеллект. Инновации. Инвестиции, 2023
The reliability of the engine largely depends on the technical condition of the fuel equipment. It is known that the efficiency of cars depends on the operating conditions that change during the seasons of the year.

The Relationship Between Geological and Environmental Aspects with the Anomalies of Track Elements and Heavy Metal Elements in the Volcanic Area of the Muria Peninsula [PDF]

open access: yesE3S Web of Conferences, 2023
The Muria Peninsula is a complex of volcanic activity located in the back arc of Sunda, which includes Kudus, Jepara, and surrounding districts. Volcanic activity on Mount Muria, can be used to study geological conditions, which were closely related to ...

Weak Imposition of Signorini Boundary Conditions on the Boundary Element Method [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2020
We derive and analyse a boundary element formulation for boundary conditions involving inequalities. In particular, we focus on Signorini contact conditions. The Calderón projector is used for the system matrix and boundary conditions are weakly imposed using a particular variational boundary operator designed using techniques from augmented Lagrangian
