New indices for analysing partial ranking diagrams
Analytica Chimica Acta, 2004Interest is growing in decision making strategies and several techniques are now available. The assessment of priorities is a typical premise before final decisions are taken. Total and partial order ranking (POR) strategies, which from a mathematical point of view are based on elementary methods of discrete mathematics, appear as an attractive and ...

On the Stories Told by Indicator Diagrams and Carnot Diagrams
Endeavour, 2018The "Carnot Diagram," so prevalent in conveying the Second Law of Thermodynamics, had a prehistory in the indicator diagrams used by some practical engineers to diagnose the ailments of steam engines and to improve their operation. These diagnoses can be understood in narrative terms, analogous to the case reports of physicians.

Mohr diagram interpretation of anisotropic diffusion indices in MRI
Magnetic Resonance Imaging, 2003Descriptions of diffusion anisotropy in MR Diffusion Tensor Imaging are often based on scalar indices such as surface-to-volume ratio, volume ratio, fractional anisotropy and rotational anisotropy. Recently, Mohr diagram was introduced to visualize the anisotropic diffusion information, but in a graphical form.

A power diagram indicator for high-tension circuits
Proceedings of the American Institute of Electrical Engineers, 1911Introduction and Summary The power diagram indicator was produced as a feasible, inexpensive instrument to observe dielectric or similar stray power losses that occur in high-tension circuits. 1 A cathode ray-pointer is used to trace the power diagram. It is actuated electrostatically.

Plumpness Analysis of Indicator Diagram for Vehicle Damper
Applied Mechanics and Materials, 2013According to the indicator diagram of damper, the indicator diagram plumpness was proposed as a quantitative index, and its mathematical relationships with the sprung mass acceleration, suspension dynamic travel and tire dynamic load were built. Moreover, the influence of the total area on suspension characteristics was analyzed in time domain and ...
