[Sutphin- Crowder correspondence] :
No full textTwo letters. In the first, Colonel D.V. Sutphin, recently returned from duty in Europe and now in private practice, writes to Major General E.L. Crowder at the request of prisoners, serving sentences, having been convicted in trials stemming from the riot on August 23, 1917. Col. Sutphin inquires as to the procedures that may be applied for possible clemency or commutation for these men. In the second, B.A. Read, as the Assistant to Maj. Gen. Crowder, replies on behalf of Crowder that there is not a specific policy in place. Each request is handled individually on its own merits
Grasping and control issues in adaptive end effectors
No full textResearch into robotic grasping and manipulation has led to the development of a large number of tendon based end effectors. Many are, however, developed as a research tool, which are limited in application to the laboratory environment. The main reason being that the designs requiring a large number of actuators to be controlled. Due to the space and safety requirements, very few have been developed and commissioned for industrial applications. This paper presents design of a rigid link finger operated by a minimum number of actuators, which may be suitable for a number of adaptive end effectors. The adaptive nature built into the end effector (due to limited number of actuators) presents considerable problems in grasping and control. The paper discusses the issues associated with such designs. The research can be applicable to any adaptive end effectors that are controlled by limited number of actuators and evaluates their suitability in industrial environments
Photoelasticity based dynamic tactile sensor
Get PDFThe paper presents design, construction and testing of a photoelasticity based dynamic sensor which is capable of detecting slip as well as providing normal force information. Starting with investigations into mechanism of slip, an approximate model of the sensor has been developed. This model explains the design improvements necessary to provide continuous signal during slip. The theoretical model also helps identify various sensor parameters to characterize the sensor. The developed sensor has been compared with other existing sensors and the experimental results from the sensor have been discussed for the type of signal the sensor provides. The sensor is also calibrated for normal force. The sensor is novel in the sense that it offers dynamic slip signal as well as the normal force information from a single contact location, it provides continuous signal during slip, and it has small size which can be easily incorporated into robotic fingers. The sensor has an edge over other existing sensors that its design is simple yet it provides strong signals which are largely unaffected by external disturbances. Copyright © 2005 by ASME
A finger mechanism for adaptive end effectors
Get PDFThis paper presents design and analysis of a rigid link finger, which may be suitable for a number of adaptive end effectors. The design has evolved from an industrial need for a tele-operated system to be used in nuclear environments. The end effector is designed to assist repair work in nuclear reactors during retrieval operation, particularly for the purpose of grasping objects of various shape, size and mass. The work is based on the University of Southampton's Whole Arm Manipulator, which has a special design consideration for safety and flexibility. The paper discusses kinematic issues associated with the finger design, and to the end of the paper specifies the limits of finger operating parameters for implementing control law
Old Chief, Crowder, and Trials by Stipulation
Get PDFIn this Article, Professor Robinson argues that the meaning of unfair prejudice and the scope of trial judges\u27 discretion in employing Rule 403 of the Federal Rules of Evidence is still uncertain following the Supreme Court\u27s recent decision in United States v. Old Chief and its vacation and remand of United States v. Crowder and United States v. Davis. Robinson evaluates the evidentiary implications of the Supreme Court\u27s recent decisions by discussing each case and analyzing the implications of the three cases read together.
Professor Robinson examines the possible effects of stipulations and admissions on the Rule 403 balancing test for exclusion of relevant evidence, highlighting the distinctions of the stipulations in Old Chief as compared to those in Crowder and Davis. In addition, he discusses the appropriate role of emotionally laden evidence in trial processes. He also ponders the scope of trial judges\u27 discretion to exclude evidence under Rule 403 after Old Chief, Crowder, and Davis. Finally, Professor Robinson analyzes the possible interpretations of Old Chief, from a very narrow reading to a very broad one, to conclude that read with Crowder and Davis, the ruling in Old Chief was relatively conservative and will likely be limited by the Court in future decisions to its specific facts or to other cases involving legal status issues. As such, traditional practices remain largely undisturbed.
Robinson notes that the Court articulated a cautious rationale for reversing the conviction in Old Chief and explains that far more sweeping change could have been effected if the court had applied differently the definition of relevancy in Rule 401 or, alternatively, the balancing test of Rule 403. Robinson concludes that Old Chief clearly means that trial judges do not have unlimited discretion to decline to exclude evidence under Rule 403 but that the extent of this limitation must await the clarification of further decision
Validation of Serious Games Attributes Using the Technology Acceptance Model
Get PDFThe paper introduces a conceptual model for the design of serious games and uses the Technology Acceptance Model (TAM) for its validation. A specially developed game introduced international students to public transport in Southampton. After completing the game, participants completed a short questionnaire and the data was analysed using structural equation modelling (SEM). The results identified the attributes and combinations of attributes that led the learner to accept and to use the serious game for learning. These findings are relevant in helping game designers and educational practitioners design serious games for effective learning
Data_Sheet_1_Transfer Free Energies of Test Proteins Into Crowded Protein Solutions Have Simple Dependence on Crowder Concentration.PDF
No full textThe effects of macromolecular crowding on the thermodynamic properties of test proteins are determined by the latter's transfer free energies from a dilute solution to a crowded solution. The transfer free energies in turn are determined by effective protein-crowder interactions. When these interactions are modeled at the all-atom level, the transfer free energies may defy simple predictions. Here we investigated the dependence of the transfer free energy (Δμ) on crowder concentration. We represented both the test protein and the crowder proteins atomistically, and used a general interaction potential consisting of hard-core repulsion, non-polar attraction, and solvent-screened electrostatic terms. The chemical potential was rigorously calculated by FMAP (Qin and Zhou, 2014), which entails expressing the protein-crowder interaction terms as correlation functions and evaluating them via fast Fourier transform (FFT). To high accuracy, the transfer free energy can be decomposed into an excluded-volume component (Δμe−v), arising from the hard-core repulsion, and a soft-attraction component (Δμs−a), arising from non-polar and electrostatic interactions. The decomposition provides physical insight into crowding effects, in particular why such effects are very modest on protein folding stability. Further decomposition of Δμs−a into non-polar and electrostatic components does not work, because these two types of interactions are highly correlated in contributing to Δμs−a. We found that Δμe−v fits well to the generalized fundamental measure theory (Qin and Zhou, 2010), which accounts for atomic details of the test protein but approximates the crowder proteins as spherical particles. Most interestingly, Δμs−a has a nearly linear dependence on crowder concentration. The latter result can be understood within a perturbed virial expansion of Δμ (in powers of crowder concentration), with Δμe−v as reference. Whereas the second virial coefficient deviates strongly from that of the reference system, higher virial coefficients are close to their reference counterparts, thus leaving the linear term to make the dominant contribution to Δμs−a.</p

On a Service-Oriented Approach for an Engineering Knowledge Desktop
Get PDFIncreasingly, manufacturing companies are shifting their focus from selling products to providing services. As a result, when designing new products, engineers must increasingly consider the life cycle costs in addition to any design requirements. To identify possible areas of concern, designers are required to consult existing maintenance information from identical products. However, in a large engineering company, the amount of information available is significant and in wide range of formats. This paper presents a prototype knowledge desktop suitable for the design engineer. The Engineering Knowledge Desktop analyses and suggests relevant information from ontologically marked-up heterogeneous web resources. It is designed using a Service-Oriented Architecture, with an ontology to mediate between Web Services. It has been delivered to the user community for evaluation
