A New and Simple Chaos Toy
We present two new, and perhaps the simplest yet, mechanical chaos demonstrations. They are both designed based on a recipe of competing nonlinear oscillations. One of these devices is simple enough that using the provided description, it can be built using a bicycle wheel, a piece of wood routed with an elliptical track, and a ball bearing. We provide a thorough Lagrangian mechanics based deri...
متن کاملA New Skewed-Rotor-Pole Switched Reluctance Motor Design
This paper considers a new switched reluctance motor (SRM) structure aiming at high starting torque with low volume. For some applications such as EVs (Electrical Vehicles), the motor volume and starting torque is a critical point in its design. In many methods, reducing the motor volume causes reduction in starting torque and decreases the motor efficiency. Unlike conventional SRMs, the rotor ...
متن کاملA New Hybrid Brushless DC Motor/Generator without Permanent Magnet
The Brushless DC (BLDC) motor is a simple robust machine which has found application over a wide power and speed of ranges in different shapes and geometry. This paper briefly reviews the fundamentals behind the motor and also the different types of BLDC motors with different geometries and then presents a new configuration for BLDC motor/generator, which does not use a permanent magnet in the ...
متن کاملEditorial Virtual reality and physical rehabilitation : a new toy or a new research and rehabilitation tool ?
Virtual reality (VR) technology is rapidly becoming a popular application for physical rehabilitation and motor control research. But questions remain about whether this technology really extends our ability to influence the nervous system or whether moving within a virtual environment just motivates the individual to perform. I served as guest editor of this month's issue of the Journal of Neu...
متن کاملExocrine pancreatic adenocarcinoma in a toy breed dog
A 4-year-old female miniature pincher with a 40-day history of weight loss, lethargy and vomiting was referred to Small Animal Hospital, Faculty of Veterinary Medicine, University of Tehran. The case also had severe jaundice, chronic diarrhoea and steatorrhoea. The efforts for saving the life of the case were not successful and finally the animal died of hypovolaemic shock and electrolyte imbal...
