A novel control system for variable rate fertilizer application based on CAN bus is presented. The system consists of variable rate controller based on DSP, ground speed sampling unit and light-bar guidance unit. These units form a control area network based on CAN bus. The variable rate controller collects signals of GPS position and ground speed, and calculates the conveyor feed shaft rotate ...

This article describes the design of a journal bearing test platform capable high-accuracy film thickness measurements via ultrasonic transducers permanently embedded in both and rotating shaft. A bespoke hydraulic loading system with programmable valves allowed application dynamic loads defined patterns, including simulation patterns found real components such as automotive connecting rod bear...

In this paper, we study N-policy for a finite population Bernoulli feedback queueing model for machine repair problem with degraded failure. The running times of the machines between breakdowns have an exponential distribution. The repair times of the machines are independent and identically distributed random variables. If at any time a machine fails, it is sent to the repairman for repairing,...

in this paper the design, implementation, and evaluation of an experimental-scale potato yield monitoring system is presented. the main objective of this research was to develop a method for accurate mapping of potato yield. at the first stage an instantaneous yield monitoring system was mounted on a potato harvesting machine. this system consisted of a weighing tray, two load cells, a shaft rp...

The processing of functionally graded materials (FGMs) using laser beam melting (LBM) is a promising technique for increasing the efficiency conventional machine components, especially e-mobility. Therefore, aim current study to prove manufacturability tailored mechanical and magnetic properties in rotor an electric motor. For this purpose, design additively manufactured rotors with application...

A bearingless induction machine has combined characteristics of induction motor and magnetic bearings. Therefore, the advantages are small size and low-cost. In the magnetic suspension of the bearingless motors, suspension forces are generated based on the feedback signals of displacement sensors detecting the movement of the rotor shaft. The suspension forces are generated taking an advantage ...

The three-dimensional organization of the smooth endoplasmic reticulum (SER) in Purkinje cell dendrites in the chick cerebellum was investigated to assess the connectivity between its various components. Three-dimensional reconstructions of the SER within portions of Purkinje cell dendrites were performed from serial sections through the cerebellar molecular layer. In addition, semithick and th...

Deep borehole cores are an important material basis for understanding deep stress conditions and rockburst risk; however, the complex environment of boreholes poses many challenges to traditional core orientation techniques, thus limiting application in fields such as situ measurement. A technical method restoring original spatial attitude nonoriented geological on ground was proposed based inh...
