Effect of alcohol additives on diesel engine performance: a review
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2021Environmental hazards are peaking as carbon dioxide emissions have exceeded critical levels. Therefore, finding and applying renewable and clean energy sources to compensate for energy needs is extremely urgent.

Failure caused by poor performance renders a system just as useless as failure caused by functional errors, and can be even more expensive to correct. For many years, performance in software systems has been achieved through a ‘fix-it-later‘ approach, using optimisation and tuning techniques. Recent evidence shows that, with the increased use of highly

Performance Engineering Case Study: Heap Construction
ACM Journal of Experimental Algorithmics, 1999The behaviour of three methods for constructing a binary heap on a computer with a hierarchical memory is studied. The methods considered are the original one proposed by Williams [1964], in which elements are repeatedly inserted into a single heap; the improvement by Floyd [1964], in which small heaps are repeatedly merged to bigger heaps; and a ...
