Analysis of OHS Costs in the Road Construction Project of Singaraja City – Mengwi (Short Cut Bedugul Point 5 - 6)

open access: diamondLogic, 2021
Short Cut Bedugul is a short road construction project on the Singaraja-Denpasar route. The short cut development includes the implementation of an occupational health and safety management system (SMK3).

Constructing bounded remainder sets and cut-and-project sets which are bounded distance to lattices [PDF]

open access: green, 2014
For any irrational cut-and-project setup, we demonstrate a natural infinite family of windows which gives rise to separated nets that are each bounded distance to a lattice. Our proof provides a new construction, using a sufficient condition of Rauzy, of

Image Sampling with Quasicrystals [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
We investigate the use of quasicrystals in image sampling. Quasicrystals produce space-filling, non-periodic point sets that are uniformly discrete and relatively dense, thereby ensuring the sample sites are evenly spread out throughout the sampled image.

Effects of Soil Properties and Slope Angle on Deformation and Stability of Cut Slopes

open access: yesAdvances in Civil Engineering, 2022
The impact of soil parameters and slope angle on the deformation and stability of cut slopes is critical for defining road project safety measurement. This study investigates the effect of soil properties and slope angle on the deformation and stability ...

The discussion about comprehensive regulation and control methods of Low and non-effective circulation layers in ultra-high water cut stage [PDF]

open access: yesE3S Web of Conferences, 2022
As the oilfield enters the ultra-high water cut stage, the development situation of water flooding is becoming increasingly severe, facing problems such as increasing natural decline, rapid water cut rise, and serious low and non-effective circulation ...

The Curled Up Dimension in Quasicrystals

open access: yesCrystals, 2021
Most quasicrystals can be generated by the cut-and-project method from higher dimensional parent lattices. In doing so they lose the periodic order their parent lattice possess, replaced with aperiodic order, due to the irrationality of the projection ...

An Exact Method to Determine the Photonic Resonances of Quasicrystals Based on Discrete Fourier Harmonics of Higher-Dimensional Atomic Surfaces

open access: yesCrystals, 2016
A rigorous method for obtaining the diffraction patterns of quasicrystals is presented. Diffraction patterns are an essential analytical tool in the study of quasicrystals, since they can be used to determine their photonic resonances.

Methods for Calculating Empires in Quasicrystals

open access: yesCrystals, 2017
This paper reviews the empire problem for quasiperiodic tilings and the existing methods for generating the empires of the vertex configurations in quasicrystals, while introducing a new and more efficient method based on the cut-and-project technique ...

Quasicrystal Tilings in Three Dimensions and Their Empires

open access: yesCrystals, 2018
The projection method for constructing quasiperiodic tilings from a higher dimensional lattice provides a useful context for computing a quasicrystal’s vertex configurations, frequencies, and empires (forced tiles).
