In this paper, we present the irst generic framework for selecting comprehensive material/energetic sustainability performance indicators (SPIs) for technical systems: the S-Cycle Performance Matrix (SCPMatrix). This novel matrix is comprised of 6 generic sustainability goals, 11 SPI archetypes, and 23 corresponding metrics identiied from our previously developed model of technical system susta...

Brain activation studies based on PET or fMRI seek to explore neuroscience questions by statistically analyzing the acquired images to produce statistical parametric images (SPIs). An increasingly wide range of univariate and multivariate analysis techniques are used to generate SPIs in order to detect mean-signal activations and/or long-range spatial interactions. However, little is known abou...

A three-dimensional fully kinetic particle-in-cell (PIC) simulation strategy has been implemented to simulate the acceleration stage of a magnetically enhanced plasma thruster (MEPT). The study performed with open-source code Spacecraft Plasma Interaction Software (SPIS). tool copiously modified properly dynamics magnetized plume. cross-validation methodology done Starfish, two-dimensional PIC ...

This paper investigates the impacts of climate change on groundwater droughts making use regional projections and standardized indices: Standardized Precipitation Index (SPI), Evapotranspiration (SPEI) Groundwater (SGI). The method adopted, using historical precipitation temperature data water levels collected in monitoring wells, first possible correlations between meteorological indices at ea...

Silicon photonic interconnect (SPI) is a promising candidate for the communication infrastructure in multiprocessor systems-onchip (MPSoCs). When employing SPIs with wavelength-division multiplexing (WDM), it is required to precisely match different devices, such as photonic switches, filters, etc, in terms of their central wavelengths. Nevertheless, SPIs are vulnerable to fabrication non-unifo...

The current study evaluates the potential of merged satellite precipitation datasets (MSPDs) against rain gauges (RGs) and (SPDs) in monitoring meteorological drought over Pakistan during 2000–2015. MSPDs evaluated include Regional Weighted Average Least Square (RWALS), (WALS), Dynamic Clustered Bayesian model Averaging (DCBA), Model (DBMA) algorithms, while set SPDs is Global Precipitation Mea...
