Hepatosplenic candidiasis: wheels within wheels.
Radiology, 1988Eight immunocompromised cancer patients with tissue-proved candidiasis underwent serial abdominal ultrasound (US) and computed tomography (CT). At US, four patterns of hepatic and splenic candidiasis were recognized, one of which the authors call a "wheels-within-wheels" pattern.

Something strange and old lurks under the ice in Antarctica, at a place called Blood Falls. It is an echo of the early Earth. Blood Falls is hard to reach and easy to find. Look through the seas of blue ice, white snow, and gray rocks for the bright-red frozen waterfall, spilling out of the ice around it in a gory cascade five stories tall.

Getting lost in nature, I can sense the unfixity of its countless forms and processes. Recurring patterns at micro and macro scale arise from creative and destructive forces in space and time; reality appears simultaneously constant and impermanent. My thesis work, a wheel inside a wheel, explores the self in relation to contemporary conceptions of ...

The use of mobile robots in applications is steadily increasing, both in the industrial and the service domains. Most mobile robots achieve locomotion using wheels. As a consequence, they are subject to differential constraints that are nonholonomic, i.e., non-integrable.

Hybrid Steering of Wheeled Wheels
2012This paper is focussed to assess the performance of a low cost steer-by-wire system developed in the Vehicle Dynamics Laboratory at Cranfield University. The steering system plays an important role in vehicle’s safety by influencing its handling performance and therefore considered as a critical vehicle system. The performance of a steer-by-wire system

Locomotive wheel-slip and wheel-lock protection
Electrical Engineering, 1950ACCIDENTS HAVE OCCURRED within recent years caused by the locking of driving wheels on diesel-electric locomotives. High-speed wheel slip is one cause of locked axles. Hence it is desirable to have some means of protecting a locomotive against wheel slip, wheel lock, motor overspeed, and wheel slide during braking.
