Southern voids : structure and cosmological implications
… effects that cause the detected distribution of voids to differ from the true distribution are discussed and suggestions are made for how to correct for these effects in the catalogue. The geometrical distribution of voids is then studied by dividing the void catalogue into two parts - wall voids …

Perceiving voids: Memory And Sight Afflictions In Contemporary Cinema
My thesis focuses on the perceptive afflictions caused by alteration of the normal biological functioning of sight and memory. These afflictions are related to the redefinition and disgregation of the classical and postclassical cinematographic characters, and affect cinematographic language, …

Behaviour of buried pipes adjacent to ground voids under dynamic loading
… increasing cyclic loading. The presence of voids located at the spring-line of the flexible buried pipes, led to a considerable increase in the soil surface settlement, pressure recorded at the pipe crown, spring-line and invert, pipe deformation and strain recorded in the pipe wall. …

Identifying shallow subsurface stratigraphy and voids using dispersive characteristics of electromagnetic and surface waves
… waves to detect subsurface stratigraphy and voids. In the first manuscript, a new technique was developed by utilizing spectral analysis of surface waves to detect subsurface openings. This technique applied the concept of group delay to evaluate the effects of subsurface voids on the phase …

High-Resolution Seismic Characterization of Shallow Sedimentary Structure for Freshwater Resources and Karstic Voids
… allow for the precise localization of subsurface voids, particularly karst formations. Numerical synthesis of directional wave packets from existing shot gathers enhances the practicality of these methods

Effects of Voids on Delamination Behavior Under Static and Fatigue Mode I and Mode II
… failure. Manufacturing process defects such as voids and fiber waviness degrade the fatigue life and delamination resistance of the blade’s composite. This research describes the effect of voids on static and fatigue interlaminar fracture behavior under mode I and mode II loading of wind turbine …

Managing the acidity of abandoned water filled coal mining voids in Collie (Western Australia) using organic matter
… pH in abandoned water filled coal mining voids in Collie was investigated. Previous studies have demonstrated that passing acidic drainage through organic matter increased the waters pH. Laboratory trials using intact sediment cores (collected from Ewington, Collie, Western Australia) were …

Systematic assessment of the influence of voids on the material performance and failure in additively manufactured polymers.
… due to various factors, the presence of voids can significantly compromise structural integrity and influence failure behavior. This study investigates the effects of voids, generated by various process parameters to simulate as-manufactured voids seen, on the mechanical performance and …

Study of Field Enhancement by Spherical Voids in Gold Lattices by Using Three Dimensional Finite Difference Time Domain Simulations
<p>Spherical voids in gold lattices have the ability to concentrate light in subwavelength dimensions resulting in a significant increase in the intensity of the light (field enhancement) near the metal surface. Field enhancement properties of nanostructured metals can significantly enhance …

Voids in the distribution of galaxies : an assessment of their significance and implications for large-scale structure formation theories
… models can be tested by the investigation of voids in the distribution of galaxies. Chapter II reviews work that has already been done on the statistics and properties of voids. In particular, attention is focussed on the establishment of a new statistic, the void probability function, which …

Supply chain innovations & firm strategy: pathways to manage institutional voids in emerging markets. Case study of manufacturing firms in Uganda
… or growing market. However, due to institutional voids, the manufacturing industry has come under pressure, which has impacted manufacturing firms' operational efficiencies. The overarching purpose of this study was to investigate why and how manufacturing firms in Uganda should apply supply chain …
