Abstract: A system of this disclosure includes an artificial intelligence module, which may include a neural network or a decision tree architecture, configured to analyze data indicative of the manner in which an operator performs tasks using a heavy machine. The artificial intelligence module is further configured to provide instructions pertaining to the control of at least some components of the heavy machine. As such, the heavy machine is operated in whole or in part based on the direction of the artificial intelligence module, which reduces reliance on a human operator. The artificial intelligence module is highly efficient, and in particular the artificial intelligence module is trained relatively quickly. Further, the artificial intelligence module may be embodied on the heavy machinery itself, as opposed to on a cloud-based system or on a more high-powered computer. Accordingly, the cost of implementing and operating the disclosed system is relatively low.

Abstract: A plate (2) for a plate kind heat exchanger (1) is disclosed. The plate (2) is provided with a plurality of corrugations (8), a cross-section of the plate (2) thereby defining a plurality of hills (9) and valleys (10) which define flow paths along surfaces of the plate (2). The hills (9) and/or the valleys (10) have a shape which is asymmetrical with respect to a center line (11, 12) intersecting a top point of the hill (9) and/or valley (10). A plate kind heat exchanger (1) having a plurality of such plates (2) arranged in a stacked configuration, where the hills (9) and valleys (10) formed in the plates (2) define flow paths between the plates (2) is also disclosed.
