The Benefit of Rail: Estimating the Impact of Station Accessibility on Residential Property Prices

open access: yesBuildings, 2022
This article focuses on the relationship between the prices and the distance from a metro or commuter railway station to residential properties. Relevant efforts have already been dedicated to estimating the effect of station accessibility, but one of ...

Role of the flat-designed surface in improving the cyclic fatigue resistance of endodontic NiTi rotary instruments [PDF]

open access: yes, 2019
The aim of this study was to investigate the role of the flat-designed surface in improving the resistance to cyclic fatigue by comparing heat-treated F-One (Fanta Dental, Shanghai, China) nickel-titanium (NiTi) rotary instruments and similar prototypes,

On Weakly Regular Rings and SSF-rings [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2006
In this work we consider weakly regular rings whose simple singular right R-Modules are flat. We also consider the condition (*): R satisfies L(a)Ír(a) for any aÎR. We prove that if R satisfies(*) and whose simple singular right R-module are flat, then Z

Flat Nonholonomic Matching [PDF]

open access: yes, 2002
In this paper we extend the matching technique to a class of nonholonomic systems with symmetries. Assuming that the momentum equation defines an integrable distribution, we introduce a family of reduced systems.

Half-flat nilmanifolds [PDF]

open access: yes, 2009
We introduce a double complex that can be associated to certain Lie algebras, and show that its cohomology determines an obstruction to the existence of a half-flat SU(3)-structure. We obtain a classification of the 6-dimensional nilmanifolds carrying an

Theoretical interpretation of modular artistic forms based on the example of contemporary Lithuanian architecture / Modulinių meninių formų teorinės interpretacijos šiuolaikinės Lietuvos architektūros pavyzdžiu

open access: yesMokslas: Lietuvos Ateitis, 2015
The article analyses modular artistic forms that emerge in all scale structures of contemporary architecture. Module, as a standard unit of measure has been in use since antiquity.

Ritchey–Common test for a 1.5 m–diameter flat mirror [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2014
This study intensively investigates the Ritchey–Common test to enable high-precision measurement of a plane mirror figure with a diameter of 1.5 m. We present a method for separating the adjustment error combined with tested data and the least–square ...

Classification of flat bands according to the band-crossing singularity of Bloch wave functions [PDF]

open access: yes, 2019
We show that flat bands can be categorized into two distinct classes, that is, singular and nonsingular flat bands, by exploiting the singular behavior of their Bloch wave functions in momentum space.

Flat semilattices [PDF]

open access: yesProceedings of the American Mathematical Society, 1978
Let S (respectively S 0 {{\mathbf {S}}_0} ) denote the category of all join-semilattices (resp. join-semilattices with 0) with (0-preserving) semilattice homomorphisms. For A ∈ S A \in
