Semi-automatic control system for hydraulic shovel
A semi-automatic control system for a hydraulic shovel has been developed. Using this system, unskilled operators can operate a hydraulic shovel easily and accurately. A mathematical control model of a hydraulic shovel with a controller was constructed and a control algorithm was developed by simulation. This algorithm was applied to a hydraulic shovel and its effectiveness was evaluated. High control accuracy and high-stability performance were achieved by feedback plus feedforward control, non
Reconstructing the Capitol
Bricks and mortar bear witness to a contest of aesthetics and evidence. Senior Architectural Historian Carl Lounsbury tells the story of the Capitol's reconstruction.
A topology construction from line drawings using a uniform plane subdivision technique
The paper describes an algorithm for constructing the topology from a set of line segments or polylines. The problem appears for example at land-maps that have been drawnby general-purpose drawing packages or captured from blue-prints by digitalisation. The solution comprises two steps; in the first step inconsistencies in the input data aredetected and removed, and in the second step the topology is constructed. The algorithm for topology construction consists of two phases: determination of a
On the material properties and constitutive equations of piezoelectric poly vinylidene fluoride (PVD
The complex elastic and piezoelectric material properties of uniaxially orientedPVDF were measured over a temperature range of 20Â°C to 80Â°C and a frequency range of0.01 Hz to 100 Hz using specially developed equipment. A WLF Time-TemperatureSuperposition (TTS) expansion of the resulting data confirmed previously reportedthermorheologically simple (TRS) behavior for the elastic properties and established thatthe piezoelectric behavior is also TRS. The form of the piezoelectric TTS expansion
Biomechanical evaluation of the intact, injured and surgically reconstructed ulnar collateral ligame
The ulnar collateral ligament (UCL) of the elbow is a major passive stabilizer againstvalgus moments and is a frequent site of injury for the professional throwing athlete. Due to theimportance of the UCL in elbow stabilization, many clinical and biomechanical studies wereconducted in the past to understand its role; however, no study has evaluated the stabilizingfunction of the UCL when subjected to a pure valgus-varus moment at varying degrees of flexion.In addition, few comparative studies ha
This applet covers an aspect of the Physical Chemistry II course that students often find confusing. Although it is based on relatively simple mathematics, a complete understanding of the phenomenon requires assimilating the following concepts: The energy levels of a diatomic molecule are given by the formula: E(v,J) = hv (v + ½) + BJ (J + 1); v = 0..infinity, J=0..infinity. A molecule absorbs light at frequencies that correspond to difference between energy levels. In this case, we are interes
is based on essays and photos provided by Peace Corps Volunteers. It asks students to create narrative cartoons that illustrate the lives of a young people in an African country.
This is an activity for circuit testing. This object is also designed for presentation via Windows-based hand-held devices.
This is an activity that shows how changes in the diameter of a circle affect the circle's other attributes; how changes in a rectangle's width and height affect its other qualities; and how changes in a triangle's width and height affect its other attributes.This object is also designed for presentation via Windows-based hand-held devices.
This is an activity in which students need to calculate how much effort, and how many pulleys are needed to lift different loads. This object is also designed for presentation via Windows-based hand-held devices.
Digital Storytelling in the Classroom and Beyond
This workshop explores how contemporary technology tools empower students and teachers to engage in highly creative and reflective tasks to organize and present information, and express emotions, ideas and knowledge through multimedia creations known as digital stories. Digital storytelling is increasingly becoming popular in schools all over the world as an engaging technology-based learning strategy. In this workshop, the participants will be exposed to powerful user-friendly and cost-free tec
Active Lessons are engaging, technology-based, student-centered (pupil-centered) learning activities designed by teachers using PowerPoint (or other presentation tool). The idea is to empower teachers to easily create technology-based activities that draw upon variety of existing and new digital resources from internet, repositories of learning objects and other sources, and require students to use technology and create artifacts demonstrating their understanding. This idea partially challenges
GLAST Large Area Telescope Simulator
The main scientific instrument on the Gamma-ray Large Area Space Telescope (GLAST) is the Large Area Telescope (LAT). This interactive computer-based educational activity allows students in grades 11-14 and informal web users to see the results when gamma-ray photons of different energies and incident angles hit the LAT. The photons convert into electron-positron pairs which travel through 19 interleaved layers of silicon into the cesium-iodide calorimeter. Background information about GLAST and
SIMply Prairie: Prairie Advocates
In this multidisciplinary, inquiry-based project students prepare a plan and give a persuasive oral presentation to create a reconstructed prairie based on research. Teachers can use this unit with their students to justify enlarging or keeping an existing prairie. This project can serve as the organizing structure for prairie study where materials from units such as The Prairie – Our Heartland become research materials. It can be used in conjunction with the unit which is taught best in the f
This is a collection of Web-based games developed from selected hands-on exhibits at the Lederman Science Center introduces students in grades 6-12 to the science and technology of Fermilab. The site is equally valuable for classroom and home use.
Frontiers of Biomedical Engineering
The course covers basic concepts of biomedical engineering and their connection with the spectrum of human activity. It serves as an introduction to the fundamental science and engineering on which biomedical engineering is based. Case studies of drugs and medical products illustrate the product development-product testing cycle, patent protection, and FDA approval. It is designed for science and non-science majors.
