3D reconstruction of cuboid-shaped objects from labeled images
… thesis, my goal is to determine a rectangular 3D cuboid that outlines the boundaries of a cuboid-shaped object shown in an image. The position of the corners of each cuboid are manually labeled, or annotated, in a 2D color image. Given the color image, the labels, and a 2D depth image of the same …

Measurement and evaluation of retail promotions
… framework termed the 'Promotion Performance Cuboid' with structural elements consisting of three foundational supply chain measures, inventory, stockouts, and performance of sales against target forecasts. The measures when viewed together through the Promotion Performance Cuboid, tell a …

Functional Information in Individual Anterior Tarsal Bones of Anthropoids
The five anterior tarsals of the foot--navicular, cuboid, first, second, and third cuneiforms--are promising candidates for good fossil preservation because of their compact shape and density, but are frequently unassociated with the more commonly preserved teeth and mandibular fragments. To be of …

Extensions to a Lemma of Bernik with Applications in the area of Metric Diophantine Approximation
… In this thesis the result is extended to a cuboid in R3 and, in fact, it is clear from the proof that the result holds in Rn. Furthermore the restriction that the polynomials must have small modulus is removed. This is the first extension of Bernik's result to consider polynomials of large …

Finite size effects in the thermodynamics of the free scalar field and the interacting SU(3) plasma
… variety of finite-size geometries (the cube, the cuboid and the parallel-plates geometries) when the field is subjected to Dirichlet and periodic boundary conditions; we also give a brief review of the thermodynamic properties of the free scalar field on discretized Euclidian space-time lattices. …

Granular Composite with Addressable and Tunable Stiffness
… caused by vacuum pressure. In this thesis, a cuboid composite material is introduced, containing internal cylindrical chambers arranged in distinct matrix configurations (2x2, 3x3, and 4x4). A custom-designed pneumatic system enables precise control over this transition, allowing for selective …

Experimental investigation on traversing hot jet ignition of lean hydrocarbon-air mixtures in a constant volume combustor
… premixed combustible mixture in a rectangular cuboid constant-volume combustor is ignited by a hot-jet traversing at different fixed speeds. The hot jet is issued via a converging nozzle from a cylindrical pre-chamber where partially combusted products of combustion are produced by spark- …

An investigation into a technique of reconstruction tomography.
… isotopes. The two containers simulated were the cuboid and the sphere, and these could be either hollow or solid. The program could create 'simulated phantoms' anywhere in three-dimensional space. It also had the capability of producing data which took into account the defects and limitations of …

3D spatial layout and geometric constraints for scene understanding
… its spatial layout abstracted as a box, object cuboids, camera viewpoint, and interactions between them. We take a supervised approach towards estimation, and learn models from training data that is fully annotated with the 3D spatial extent of objects, walls, and floor. We assume the world is …

3-D Reconstruction of Multi-object Scenes from Multiple Images
… the shape of the scene aside from the bounding cuboid. This representation is smoothed by fitting a Radial Basis Function implicit surface, which smoothes noise and interpolates any missing data. Errors which persist are addressed by a matching surface points between images and estimating the …

Hydraulic and fluvial geomorphological models for a bedrock channel reach of the Twenty Mile Creek /
… movement in the study reach. An imaginary unit cuboid (1 metre by 1 metre by 1 metre) boulder was also envisioned to determine the general propensity for the movement of such a boulder through the bedrock system. The efforts and findings of this study provide a standardized means for the …

Finite element time domain method with a unique coupled mesh system for electromagnatics and photonics
… The rectangular computational domain in 2D and cuboid computational domain in 3D sometimes makes the method very resource intensive especially for large simulations. Although the finite element (FE) approach is superior for the discretisation of both 2D and 3D structures, most of the FE-based …

Microfluidic assembly and packing dynamics of colloidal granules
… in the form of microgear, triangular, discoid, cuboid, and rectangular shapes are produced by this approach. In addition, pathways are demonstrated that allow these building blocks to be transformed into both porous and dense oxide and non-oxide structures. Finally, large quantities of …

3D scene and object parsing from a single image
… across panoramas and perspective images, cuboid layouts and more general layouts (e.g., “L”-shape room). We then make use of an additional depth image, explore at the scene level to recover the complete 3D scene with layouts and all objects jointly. At the object level, we propose to …

Extremal Combinatorics and Universal Algorithms
… chain decomposition of a 2 × 2 × ... × 2 × n cuboid (k 2’s) such that no chain has a subchain of the form (a1,...,ak,0) ≺ ... ≺ (a1,...,ak,n−1)? We show this is true precisely when k≥5 and n≥3. Thisquestion arises naturally when considering products of symmetric chain decompositions which …
