A New Simple Method for Estimating Exergy Destruction in Heat Exchangers

This paper presents an abbreviated method for estimating exergy destruction in a heat exchanger, requiring only black-box data of the exchanger’s inputs and outputs, and eliminating part of the mathematical difficulties associated with the calculations. A well-known model for temperature distributions in an exchanger is adapted for this case, and is used to distinguish between the contributions...

Estimating cut points: A simple method for new wearables.

UNLABELLED Wearable technology is readily available for continuous assessment due to a growing number of commercial devices with increased data capture capabilities. However, many commercial devices fail to support suitable parameters (cut points) derived from the literature to help quantify physical activity (PA) due to differences in manufacturing. A simple metric to estimate cut points for n...

A Simple Method of Bug Destruction

One of the minor problems of hospital administration in the East is the elimination of bugs from the wards. The reputation of a hospital, especially among the general public, is sometimes gauged by the presence or absence of this pest. There are innumerable ways of destroying the bed-bug, but it is doubtful if the time and money spent 011 disinfection is commensurate with the results, for 110 s...
