Damping-off - a short on a type of plant disease Damping-off is a movie short on the widespread but mostly unnoticed disease of plants. I say unnoticed because the plants appear to wilt away and most would conclude the cause was limitation of plant available moisture. The movie short exposes the secretive predation of plants, especially seedlings, by several types of pathogenic microbes commonly lurking in the soil. All content is of native plants and plant communities. Our heroine, black cherry, is one of the most valuable timber species in the USA and is the source of cherry wood used in fine woodworking. Many other plant species are affected by Pythium, however, the movie focuses on black cherry because it was the focus of Kurt's research for several years.

Mass-Spring Systems 3: Critically Damped Motion ODEs: Consider spring motion governed by the IVP x"+4x' +4x = 0, x(0) = 1, x'(0) = 0. From the solution, we describe the motion of the spring and plot the trajectory in the phase plane. In this case, there is no oscillation and exactly one dimension of eigenvectors.

Raincheck - Acoustic Damping Membrane Acoustic innovators Sound Reduction Systems Ltd have developed the perfect acoustic damping material to reduce the noise generated by rain falling on metal profiled roofing systems.

Quad rotor rate damping 2 In today's video, angular rates have been limited enough for a human to control the tilt reasonably well. The key was increasing the PWM to 100Hz, using nonlinear feedback curves, increasing gyro bandwidth. At higher power levels, the angular rates R still out of control. That might be ground effect or gyro aliasing from propeller vibrations.

Kawasaki KLR 650..... rear shock damping adjustment..... This video demonstrates how to adjust the "Damping" on the rear shock absorber of a 2006 Kawasaki KLR 650. A few fellow KLR owners and I were in search of the rear damping adjustment and it is now found. I am posting this in case anyone out there is in search of it. The owners manual does a poor job of explaining the location of this. I guess if you weigh more than the average rider you should adjust this. I have mine on 3 and will test it out.

Hurricane Damping and Prevention SwissInvents Project Idea for Google's 10^100 Challenge. Hurricane Damping and Prevention by cooling down the sea surface. Reducing number and strength of hurricanes impacting coastal regions through wind powered pumps distributing cold deep sea water on the ocean surface. The project aims to control formation and strength of cyclones by cooling the sea surface with 6 °C cold water from depths, less than 1000m, pumped up by floating, mobile and steerable offshore platforms with tubes, reaching down to the required depth and importantly, using the same platforms also to produce clean, renewable energy. In future, some of the fleets would evolve into sea based, floating cities, using some of the locally produced energy, living on aqua culturing and fish farming. Properly built, the growing islands could enhance cyclone control and strengthen the albedo effect to reduce global warming.

Another Mathews Innovation: Harmonic Damping In 2000, Mathews introduced Harmonic Dampening, a pair of weights that float in elastic bushings on either side of the riser. Harmonic Dampening helps two ways: 1. Cancels vibration when recoil vibration encounters the dampers, they become weight-in-motion that is out of phase with the vibration. The result is a canceling or absorption of the vibration. 2. Reducing torque- locating the dampers (weights on either end of the riser) effectively reduces hand torque through what is called the barbell effect.

New Acoustic Damping Adhesive from Green Glue Markertek News Channel coverage of Green Glue acoustic damping adhesive. Green Glue is a constrained layer damping system, which as a damping material is sandwiched between two other rigid materials such as two sheets of drywall or any other porous building material. Damping occurs when the viscoelastic center of the "sandwich" is sheared. Green Glue works effectively against any impact or airborne noise control problem. Green Glue can be used over any existing wall, floor or ceiling by simply adding another layer of material. No rolling, painting or troweling is necessary. Just open the tube and apply in a random pattern. With a fast and easy installation, anybody can soundproof a room with Green Glue.

Motion Damping With Air Dashpots The different response characteristics when pulling vs. pushing on the dashpot piston. A dashpot piston includes a low friction graphite piston, a glass cylinder, a metal mount that houses a valve on one end and a rod attached to piston on the other end. The rod is attached to a 400-gram weight falling by gravity inside the demonstrator. In push damping the piston will compress air and build up enough pressure in order to resist the weight. In pull damping, you are creating a partial vacuum. The advantage is that the pressure differential builds much quicker and the user gets damping right at the start of the stroke.

EDWARD - Electric Diwheel With Active Rotation Damping This project by students in the School of Mechanical Engineering, the University of Adelaide involved the construction of a human operated diwheel called EDWARD. Many diwheels in the past have been human powered or powered by IC engines. This one is purely electric. It has additional functionality lacking in other models, including inbuilt dynamic lateral stability and slosh control to prevent "gerbiling" or tumbling in aggressive braking or acceleration maneuvers. The diwheel also incorporates a unique feature that allows the rider to drive the vehicle when "upside down" - keeping the vehicle in its unstable state. This video shows the outcomes from the developments during 2010, which includes successful slosh control, swing-up and inversion control.

Active Vibration Damping The PolyPower DEAP technology can be utilized for active vibration control: Here we demonstrate the capability of InLastor® Push element for cancellation of vibrations by isolating a steel measuring tape on its top from base vibration. Innovative technology for new solutions! The base vibration is generated by an electro-dynamic shaker. When active isolation control is turned on the length of the InLastor element is controlled so that the top position of the element remains in a constant position, ie the top position is isolated from base vibration.

Motion Damping Thrust Vector Control System for Marine Craft This, our patented early prototype, was a bold leap forward in both manned and unmanned marine technology. The World's First motion damping capable thrust vector control system for planing craft; she convincingly demonstrated: Dynamic Computer Directed Attitude Control and Stabilization (pitch, roll & yaw); Coordinated and Unusual Attitude Turn Options; Improved Planing Performance; Improved Ride Comfort; Reduced Operator / Passenger Fatigue; and Automated Compensation for Weight Distribution Irregularities. Designed for scalability and propulsion system integration flexibility (ie Prop, Waterjet, Outboard Motor, Outdrive, Sterndrive, Surface Drive, etc.), the control system is inherently capable of accommodating vessels of varying performance and size.

E-Safe High damping rubber bearing under testing The Agom high damping rubber bearings E-Safe HDRB consist of multiple elastomer layers made of special dissipative rubber compounds, separated by reinforcing steel plates moulded to the rubber layer, and can be manufactured in a rectangular or circular shape according to customer requirements. In the HDRB isolator, the energy is dissipated by hysteresis by the special rubber compound during the cycles of horizontal deformation of the insulator. The damping factor of HDRB can reach 10-15%. All the qualification and approval tests are performed by independent and worldwide-recognized laboratories to assure the isolators' performances comply with the project and international standard requirements.
