in different projects the speed of different machinery can be estimated using manufacturer's handbooks and a number of modification factors to consider the environmental effects, type of the project and status of site management. since the statuses of different factors of the domestic projects are totally different from those of the international projects, there is a wide discrepancy betwe...

The paper discusses electrohydraulic variable supply systems in different design concepts. In the forefront of discussion are concepts with constant and speed-controlled electric motor combination pumps, implemented within control strategies.

in recent decades, canola has been considered as the most important oilseed. harvesting is the most major problem of canola cultivation, since canola pods are very sensitive to shocks and vibrations. large amount of produce will fall on the ground especially when the combine's head is not adjusted properly. when canola harvested with a combine, the losses may reach up to 50%. the yields can be ...

distribution of water vapor in the atmosphere of the room poultry houses is usually an effective and economical solution to reduce heat stress of the chickens. experimental studies were conducted in a small saloon located in the farm machinery department of shiraz university. the rotary cup fogging system consisted of a cup which was derived by dc motor. rotational speed of the cup caused the w...

I propose to consider the question, “Can machines think?” This should begin with definitions of the meaning of the terms “machine” and “think.” The definitions might be framed so as to reflect so far as possible the normal use of the words, but this attitude is dangerous, If the meaning of the words“machine”and “think” are to be found by examining how they are commonly used it is difficult to e...

Eccentricity detection is a crucial issue for highspeed rotating machinery, which concerns the stability and safety of the machinery. Conventional techniques in industry for eccentricity detection are mainly based on measuring certain physical indicators, which are costly and hard to deploy. In this paper, we propose RED, a non-intrusive, low-cost, and realtime RFID-based eccentricity detection...
