Pneumatic Conveyance of Fiber Assemblies

Distributed Pneumatic MEMS for Fast Conveyance of Fragile Objects

In this paper we present a distributed and modular system to convey small and fragile objects. This is done by attaching similar modular blocks together to form a larger conveyance surface. Similar to other networked control systems, each block is composed of several sensors, actuators and communication infrastructure. Control of a levitating object should be done distributed and real-time. We ...

Optical flow profiling method for visualization and evaluation of flow disturbances in agricultural pneumatic conveyance systems

Pneumatic conveying is widely used for transporting granular materials and agricultural products. Traditional flow visualization methods are used extensively in experimental fluid dynamics but have not been commonly used with agricultural products as the flow seeding particle. A flow visualization method that can provide qualitative flow visualization images and quantitative values to describe ...

Photo-realistic rendering of fiber assemblies

In this thesis we introduce a novel uniform formalism for light scattering from filaments, the Bidirectional Fiber Scattering Distribution Function (BFSDF). Similar to the role of the Bidirectional Surface Scattering Reflectance Distribution Function (BSSRDF) for surfaces, the BFSDF can be seen as a general approach for describing light scattering from filaments. Based on this theoretical found...

Conveyance of Contagion by Flies

An Anglo-Indian, asked to mention the principal annoyances attending every-day life in this country, would probably catalogue heat, musquitoes, sparrows, and various kinds of winged insects, not forgetting the irrepressible house fly?a dipteron which, whether acting under dense ignorance of danger, or whether influenced by pure impudence, does not hesitate to explore, even at the risk of destru...
