Modular robots for sorting
No full textCurrent industrial sorting systems allow for low error, high throughput sorts with tightly
constrained properties. These sorters, however, are often hardware limited to certain
items and criteria. There is a need for more adaptive sorting systems for processes that
involve a high throughput of heterogeneous items such as import testing by port authorities, warehouse sorting for online retailers, and sorting recycling. The variety of goods
that need to be sorted in these applications mean that existing sorting systems are unsuitable, and the objects often need to be sorted by hand. In this work I detail my design
and control of a modular, robotic sorting system using linear actuating robots to create
both low-frequency vibrations and peristaltic waves for sorting. The adaptability of
the system allows for multimodal sorting and can improve heterogeneous sorting systems.
I have designed a novel modular robot called the Linbot. These Linbots are based on
an actuator design utilising a voice coil for linear motion. I designed this actuator to be
part of a modular robot by adding on-board computation, sensing and communication. I
demonstrate the individual characteristics of these robots through a series of experiments
in order to give a comprehensive overview of their abilities. By combining multiple
Linbots in a collective I demonstrate their ability to move and sort objects using
cooperative peristaltic motion.
In order to allow for rapid optimisation of control schemes for Linbot collectives I
required a peristaltic table simulator. I designed and implemented a peristaltic table
simulator, called PeriSim, due to a lack of existing solutions. Controllers optimised in
simulation often suffer from a reduction in performance when moved to a real-world
system due to the inaccuracies in the simulation, this effect is called the reality gap. I
used a method for reducing the reality gap called the radical envelope of noise hypothesis,
whereby I only modelled the key aspects of peristalsis in PeriSim and then varied the
underlying physics of the simulation between runs. I used PeriSim to optimise controllers
in simulation that worked on a real-world system.
I demonstrate the how the Linbots and PeriSim can be used to build and control an
adaptive sorter. I built an adaptive sorter made of a 5x5 grid of Linbots with a soft
sheet covering them. I demonstrate that the sorter can grade produce and move objects
of varying shapes and sizes. My work can guide the future design of industrial adaptive
sorting systems
Perfect Competition
No full textIn his 1987 entry on ‘Perfect Competition’ in The New Palgrave, the author reviewed the question of the perfectness of perfect competition, and gave four alternative formalisations rooted in the so-called Arrow-Debreu-Mckenzie model. That entry is now updated for the second edition to include work done on the subject during the last twenty years. A fresh assessment of this literature is offered, one that emphasises the independence assumption whereby individual agents are not related except through the price system. And it highlights a ‘linguistic turn’ whereby Hayek’s two fundamental papers on ‘division of knowledge’ are seen to have devastating consequences for this research programmeAllocation of Resources, Perfect Competition, Exchange Economy

Regional compilation and analysis of aeromagnetic anomalies for the Transantarctic Mountains–Ross Sea sector of the Antarctic
No full textMagnetic observations over the area of the Transantarctic Mountains (TAM) and the Ross Sea have been compiled into a digital database that furnishes a new regional scale view of the magnetic anomaly crustal field in this key sector of the Antarctic continent. This compilation is a component of the ongoing IAGA/SCAR Antarctic Digital Magnetic Anomaly Project (ADMAP). The aeromagnetic surveys total 115000 line km, and are distributed across the Victoria Land sector of the TAM, the Ross Sea, and Marie Byrd Land. The magnetic campaigns were performed within the framework of the national and
international Italian–German–US Antarctic research programs and conducted with differing specifications during nine field
seasons from 1971 until 1997. Generally flight line spacing was less than 5 km while survey altitude varied from about 610 to 4000 m above sea level for barometric surveys and was equal to 305 m above topography for the single draped survey. Reprocessing included digitizing the old contour data, improved levelling by means of microlevelling in the frequency domain, and re-reduction to a common reference field based on the DGRF90 model. A multi-frequency grid procedure was then applied to obtain a coherent and merged total intensity magnetic anomaly map. The shaded relief map covers an area of approximately 380000 km2. This new compilation provides a regional image of the location and spatial extent of the Cenozoic alkaline magmatism related to the TAM–Ross Sea rift, Jurassic tholeiites, and crustal segments of the Early Palaeozoic magmatic arc. A linear, approximately 100-km wide and 600-km long Jurassic rift-like structure is newly identified. Magnetic fabric in the Ross
Sea rift often matches seismically imaged Cenozoic fault arrays. Major buried onshore pre-rift fault zones, likely inherited from
the Ross Orogen, are also delineated. These faults may have been reactivated as strike-slip belts that segmented the TAM into
various crustal blocks.Published121-137JCR Journalreserve

Evaluation of a primer used to orient students and instructors to the role of a sign language interpreter in the classroom: a focus group study
No full textPlan BThe Center for Special Needs at Milwaukee Area Technical College (MATC) provides interpreting services to deaf and hard-of-hearing students enrolling in a wide range of classes and programs across the institution. A primer entitled An Interpreter in the Classroom was devised to clearly delineate the roles and responsibilities of students, interpreters, and instructors in a classroom interpreting situation. The manual was printed and found to have numerous errors and shortcomings. The purpose of this study was to develop recommendations for the revision of the primer. Fifteen potential users of the manual were recruited from MATC to attend the focus group sessions. The objectives of these focus groups were to: identify information in the current primer that was incorrect or outdated; develop suggestions for incorporating specific changes in the field of interpreting (or education as a whole) into an update
