Patterns of Optimal Structural Layouts
… Analytical solutions for optimal structural layouts of plates and beam systems comprised of one-dimensional elements were derived by Rozvany et al. in the 1970s. This thesis explores optimal structural layouts in the context of conventional and other nonconventional beam layouts (e.g. derived …

Numeric Keyboard Layouts: An Ergonomic Approach
<p>This study investigated the most effective method of numeric data entry, by means of a numeric keypad. The methods of numeric data entry were (a) two keypads with different numerical configurations, (b) two keypads with identical numerical configurations, and (c) one keypad with only a single …

Recognition and identification of form document layouts
In this thesis, a hierarchical tree representation is introduced to represent the logical structure of a form document. But different forms might have the same logical structure, so the representation will be ambiguous. In this thesis, an improvement is proposed to solve the ambiguity problem by …

Optimum gate arrangements for MOS standardized layouts
Optimization of size is an important topic of research in the engineering of digital circuits. The field effect transistor (FET) is making an important contribution in this area. In this paper, the basic properties of the FET which pertain to digital circuits will be examined. The problems …

Instance-Optimized Database Indexes and Storage Layouts
… designs for database indexes and data storage layouts that outperform existing state-of-the-art indexes and data layouts by orders of magnitude. We also demonstrate how to incorporate multiple instance-optimized database components into an end-toend analytic database system that outperforms a …

CAD oriented database for integrated circuit layouts
Modern integrated circuit layouts are so complex that databases often have to deal with a million or more geometric objects. For circuit and layout designers to be able to cope with such complex circuits, we (tool designers) must provide more and more support in such areas as design rule checking, …

ACT-R Based Models For Learning Interactive Layouts
… presents research on learning of interactive layouts. I develop two models based on a theory of cognition known as ACT-R (Adaptive Control of Thought–Rational). I validate them against experimental data collected by other researchers. The first model is a simulation model that emulates the …

Optimizing Data Layouts for Evolving Cloud Table Storage
… due to expensive data movement. Effective data layouts, which organize data to minimize unnecessary data reads, are thus critical to achieving high query performance. However, existing techniques typically rely on manually specified layouts, collect limited metadata, or lack mechanisms to …

Simulation and comparative evaluation of flexible automotive assembly layouts
Equipment malfunction, logistics errors, and other disturbances in automobile factories can be very costly for manufacturers, as they often result in assembly line downtime until the problem is resolved. In this thesis, we examine a new concept for a Flexible Assembly Layout, enabled by new mobile …

Optimization of Wind Turbine Airfoils/Blades and Wind Farm Layouts
<p>Shape optimization is widely used in the design of wind turbine blades. In this dissertation, a numerical optimization method called Genetic Algorithm (GA) is applied to address the shape optimization of wind turbine airfoils and blades. In recent years, the airfoil sections with blunt trailing …

Exploring the powers of stacks and queues via graph layouts
In this dissertation we employ stack and queue layouts of graphs to explore the relative power of stacks and queues. Stack layout and queue layouts of graphs can be examined from several points of view. A stack or a queue layout of a graph can be thought of as an embedding of the graph in a plane …

Optimizing acoustic design and schematic architectural layouts of office buildings
… These nature-inspired thematic architectural layouts have been increasingly used in recent years by many architects. This architectural design task is often complex and challenging as it requires the creation of optimal architectural layouts that resemble the selected image from nature while …

A user interface for customizing cane layouts in Virtual Glass
Cane pulling is a technique used in glass blowing to build up intricate patterns which come out in the final piece. Virtual Glass was created to model the cane pulling process from start to finish. There are a variety of standard cane layout patterns, but in truth the full range of possibilities is …

Mathematics Page Format: Student Experience with High-and Low-Density Layouts
… given the choice between two differing math page layouts. One choice was characterized by thirty problems on the page, hereafter termed "high-density" (see Appendix A). The other choice included the same problems spread out over five "low-density" (see Appendix B) pages. In two more classrooms the …

BlendDB : blending table layouts to support efficient browsing of relational databases
The physical implementation of most relational databases follows their logical description, where each relation is stored in its own file or collection of files on disk. Such an implementation is good for queries that filter or aggregate large portions of a single table, and provides reasonable …

An integrated system to design machine layouts for modular special purpose machines
… of an integrated system for the design of layouts for special purpose machines (SPMs). SPMs are capable of performing several machining operations (such as drilling, milling, and tapping) at the same time. They consist of elements that can be arranged in different layouts. Whilst this is a …
