Susan Symmes to Susan Kean, June 21, 1800
No full textSusan Symmes wrote to Susan Kean in Elizabethtown, New Jersey. Susan Symmes executed the few commissions Susan Kean honored her with and hoped the articles suited her; felt the muslin was cheap for the quality. There were no Cincinnati Eagles to be purchased, her brother had two, one of which he would send Susan if it could be found. Symmes and Miss Ludlow sallied forth the day prior in quest of the things and she enclosed the accounts. In the bundle were two handkerchiefs for Betty and Mary. Thought she saw Susan’s brother next door but was mistaken.https://digitalcommons.kean.edu/lhc_1800s/1114/thumbnail.jp

RoMEO Studies 4: An analysis of Journal publishers' Copyright Agreements
No full textThis article is the fourth in a series of six emanating from the UK JISC-funded RoMEO Project (Rights Metadata for Open archiving). It describes an analysis of 80 scholarly journal publishers’ copyright agreements with a particular view to their effect on author self-archiving. 90% of agreements asked for copyright transfer and 69% asked for it prior to refereeing the paper. 75% asked authors to warrant that their work had not been previously published although only two explicitly stated that they viewed self-archiving as prior publication. 28.5% of agreements provided authors with no usage rights over their own paper. Although 42.5% allowed self-archiving in some format, there was no consensus on the conditions under which self-archiving could take place. The article concludes that author-publisher copyright agreements should be reconsidered by a working party representing the needs of both partie
An electric wheelchair mounted robotic arm - a survey of potential users
No full textThis paper describes the results of a survey which investigated and evaluated the needs and abilities of electric wheelchair users. The results of this survey will be used to develop a low-cost electric wheelchair-mounted robotic arm for use by physically disabled people to facilitate rehabilitation. The survey was undertaken by the author together with staff and students from occupational therapist training colleges, using a four-page questionnaire containing over 110 questions. The questionnaire was developed by the author together with Dr Robin Platts (Director of Orthotics), Mr Ian Bayley (Director of the London Spinal Unit) and senior occupational therapists at the Royal National Orthopaedic Hospital, Stanmore, Middlesex. After a successful trial the questionnaire was used with 50 severely disabled people from various backgrounds and social circumstances. The results of this survey show that the average electric wheelchair user is 40 years old, single (68%), living at home (58%) with family support (69%) and without any paid employment (79%). The most prevalent disability is spinal cord injury (24%) followed by multiple sclerosis (16%). The survey has identified several tasks which electric wheelchair users find impossible to do, and some of these will form part of the design specification. Finally 84% of the survey subjects would consider buying such a robotic ai
Simulation and Control of a Pneumatic Muscle Actuator for a Rehabilitation Robot
No full textThe perfomance of a pneumatic muscle actuator, invented by Jim Hennequin and used in a prototype wheelchair-mounted robot ann designed by the first author is reported. Experimental measurements were made of the output torque versus rotary motion and internal pressure. The torque available for a muscle of size 60 mm width by 90 mm length ranges from 1 to 15 Nm. The rotary stiffness of this muscle is 0.081 Nm/deg. A simulation model of the dynamic behaviour of the muscle attached to the robot arm using one-dimensional flow theory was written in ACSL (Advanced Continuous Simulation Language). The resultant simulation gives good agreement to within ± 5% of the experimental values. Control using proportional and a PID controller is shown to be effective
Including design in e-manufacturing
No full textThis paper reviews major issues in the implementation of e-manufacturing, particularly the design aspects. It will examine recent progress, drawing out particular issues that are being addressed. Use will be made of the work by the author and colleagues to devise rule-based design and Internet-based control of machines to illustrate how these developments affect the integrated e-manufacturing environment. A dynamic Simulink model of the way e-manufacture is affected by overall design delays is used to evaluate general solutions for partial and complete e-based companies. These models show how changing to improved designs reduces WI

Energy conservation techniques: increasing the endurance of small UAVs
No full textAll small Unmanned Aircraft (UA) have severe limitations from a lack of endurance capability. This is a direct result of using battery technologies which are limited in their capacity, current capability, mass and energy density. The most widely used chemistry in small battery powered UAVs is Li-Po with its peak energy density of about 200 Wh/kg. Much research has been directed at finding alternative power sources, from Solar, Hydrogen Fuel Cells to Nuclear batteries. The latest contender is Li-S chemistries which appear to offer energy densities of up to 400 Wh/kg within the next 2 years. Li-S batteries claim to be safer in terms of damage tolerance and the lack of thermal runaway, which can be an issue with the current generation Li-Po batteries. This presentation will outline the alternatives and point towards the likely future direction of this technology. The author will also present other design strategies and design tools which help to promote the efficient use of power within these types of Unmanned Aircraft
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
