Invitation to David Bishop from the Order of United Americans for a celebration of George Washington's birthday, February 1858
No full textThe Order of United Americans, also known as the Know-Nothings, formed in the mid-1800s to support the rights of native-born Americans over those of immigrants, and to combat what they saw as foreign influences on America. This letter is an invitation to Order member David Bishop, to a celebration in honor of George Washington's birthday. Page 1 shows the actual letter, and page 2 is the transcripts of the letter
Dynamic Electrical-Magnetic-Thermal Simulation of Magnetic Components
No full textThis paper describes how the modeling and simulation of electro-magnetic devices can be extended to include dynamic thermal effects. The power generated by hysteresis inside ferrite cores is connected to a thermal model of the core material. The thermal conduction of the core material is modeled as is the convection of thermal energy from the core to the surrounding environment. The effective temperature change inside the core is used to modify the parameters of the core material model to accurately reflect the dynamic performance of the device at all temperatures. The electrical circuit, magnetic material and thermal networks are all modeled concurrently in the time domain to allow dynamic interactions across all three domains

Behavioural synthesis utilising recursive definitions
No full textBehavioural synthesis is the process of automatically translating an abstract specification to physical realisation - silicon. The endpoints of this process are accelerating apart (behavioural descriptions become more abstract, DSM silicon becomes less willing to behave as Boolean circuits) but there is still work outstanding in the middle ground. Recursion allows the elegant expression of complicated systems, and is supported by many languages (software and hardware). The electronic design automation (EDA) tool designers- task is to support the semantics of a language (both simulation and synthesis). Although recursive descriptions can always be re-cast into non-recursive iterative forms, if a language supports a construct, a user should be able to utilise it (the authors are not offering any opinion on the relative wisdom of using recursion or iteration). The authors describe the problems/solutions of supporting the semantics of recursion (single/multiple, direct/arbitrarily indirect) in synthesis. The hardware synthesised can be smaller and faster than that obtained by reformulating the description. It is dangerous, to conclude too much from this - recursion requires a stack and a heap (plus managers). In software, these are taken for granted (-free- resources that do not feature in footprint metrics); in hardware, every resource needed must be explicitly created
Supervisory fuzzy learning control for underwater target tracking
No full textThis paper presents recent work on the improvement of the robotics vision based control strategy for underwater pipeline tracking system. The study focuses on developing image processing algorithms and a fuzzy inference system for the analysis of the terrain. The main goal is to implement the supervisory fuzzy learning control technique to reduce the errors on navigation decision due to the pipeline occlusion problem. The system developed is capable of interpreting underwater images containing occluded pipeline, seabed and other unwanted noise. The algorithm proposed in previous work does not explore the cooperation between fuzzy controllers, knowledge and learnt data to improve the outputs for underwater pipeline tracking. Computer simulations and prototype simulations demonstrate the effectiveness of this approach. The system accuracy level has also been discussed

Applications and Advances in Electronic-Nose Technologies
No full textElectronic-nose devices have received considerable attention in the field of sensor technology during the past twenty years, largely due to the discovery of numerous applications derived from research in diverse fields of applied sciences. Recent applications of electronic nose technologies have come through advances in sensor design, material improvements, software innovations and progress in microcircuitry design and systems integration. The invention of many new e-nose sensor types and arrays, based on different detection principles and mechanisms, is closely correlated with the expansion of new applications. Electronic noses have provided a plethora of benefits to a variety of commercial industries, including the agricultural, biomedical, cosmetics, environmental, food, manufacturing, military, pharmaceutical, regulatory, and various scientific research fields. Advances have improved product attributes, uniformity, and consistency as a result of increases in quality control capabilities afforded by electronic-nose monitoring of all phases of industrial manufacturing processes. This paper is a review of the major electronic-nose technologies, developed since this specialized field was born and became prominent in the mid 1980s, and a summarization of some of the more important and useful applications that have been of greatest benefit to man
