Electricity price prediction through statistical and machine learning techniques captures market trends would be a useful tool for energy traders to observe fluctuations increase their profits over time. A Nonlinear AutoRegressive Moving Average model with eXogenous inputs (NARMAX) identifies key energy-related factors that influence hourly electricity modelling. We propose use transparent NARM...

the aim of this research paper is the introduction of a novel mathematical approach to improvethe accuracy of the results of air pollution dispersion models based on the calibration of input backgroundconcentrations. using the dunkirk area of the city of nottingham in the uk as a case study, an air pollutionmodel in adms-roads was created for developing the mathematical approach. the iterative ...

D URING A STUDY" 2 of variations in serum cholesterol, we observed striking changes from day to day in certain subjects. In a few individuals the change in serum cholesterol was more than 200 mg. per cent from one morning to the next. In sharp contrast , in other subjects the level of serum cholesterol seemed quite stable. Similar observations have been made by Thomas and Eisenberg.3 The tenden...

Hourly rounds—intentionally checking on patients at regular intervals—continues to be debated in nursing circles. Often, registered nurses make rounds on even hours and support staff make rounds on odd hours from 6 AM to 10 PM (and every 2 hours from 10 PM to 6 AM). While making rounds, staff engage patients by checking on the “4 P’s”: pain, positioning, potty (elimination), and proximity of pe...

The dynamics of hourly electricity prices in day-ahead markets is an important element of competitive power markets that were only established in the last decade. In electricity markets, the market microstructure does not allow for continuous trading, since operators require advance notice in order to verify that the schedule is feasible and lies within transmission constraints. Instead agents ...

It is ironic that many clients and lawyers now condemn hourly billing. Starting in the 1950s, both groups demanded the switch from fixed-fee billing to hourly billing. This article explains why. Using a new economic model, Professors Cloud and Shepherd show that societal changes, particularly the expansion of pretrial discovery in the 1938 Federal Rules of Civil Procedure, led inevitably to hou...
