A phantom based evaluation of the clinical imaging performance of electronic portal imaging devices.

Purpose: In this study an evaluation of the imaging performance of an electronic portal imaging device (EPID) is presented. The evaluation performed employing the QC-3V image quality phantom.

Methods: An EPID system of a 6 MV LINAC, was used to obtain images of a QC-3V EPID phantom.

Resource Recovery and the Sherwood Plot.

Our work analyzes the biophysical and economic foundations of the (SP). In general, the SP depicts the theoretical relationship between the a target material or an identified (VAC) from a waste matrix and its in the waste matrix; specifically suggesting that the recovery cost is reverse proportional to the VAC's dilution in it. We further utilize the SP as a scientifically consistent and economically coherent analytical framework for measuring performance.

Data and code for the exploratory data analysis of the electrical energy demand in the time domain in Greece.

We present data and code for visualizing the electrical energy data and weather-, climate-related and socioeconomic variables in the time domain in Greece. The electrical energy data include hourly demand, weekly-ahead forecasted values of the demand provided by the Greek Independent Power Transmission Operator and pricing values in Greece. We also present the daily temperature in Athens and the Gross Domestic Product of Greece.

Sewer-mining: A water reuse option supporting circular economy, public service provision and entrepreneurship.

Water scarcity, either due to increased urbanisation or climatic variability, has motivated societies to reduce pressure on water resources mainly by reducing water demand. However, this practice alone is not sufficient to guarantee the quality of life that high quality water services underpin, especially within a context of increased urbanisation. As such, the idea of water reuse has been gaining momentum for some time and has recently found a more general context within the idea of the Circular Economy.
