Customer self-service technologies (SST) have been gaining increasing economic importance given their proliferation in the customer service industry. Self-service kiosks have gradually been replacing traditional service employees and their progress is expected to continue. The growing relevance of SST results in the need for companies to understand why customers are willing to use SST and which...

From 1998-2013, MIT Lincoln Laboratory operated a highly successful near-Earth asteroid search program using two 1-m optical telescopes located at the MIT Lincoln Laboratory Experimental Test Site (ETS) in Socorro, N.M. In 2014, the Lincoln Near-Earth Asteroid Research (LINEAR) program successfully transitioned operations from the two 1-m telescopes to the 3.5-m Space Surveillance Telescope (SS...

Holocene climate variability is investigated in the North Pacific and North Atlantic realms, using alkenone-derived sea-surface temperature (SST) records as well as a millennial scale simulation with a coupled atmosphere-ocean general circulation model (AOGCM). The alkenone SST data indicate a temperature increase over almost the entire North Pacific from 7 cal kyr BP to the present. A dipole p...

An neural network model of data mining is used to identify error sources in satellite-derived tropical sea surface temperature (SST) estimates from thermal infrared sensors onboard the Geostationary Operational Environmental Satellite (GOES). By using the Back Propagation Network (BPN) algorithm, it is found that air temperature, relative humidity, and wind speed variation are the major factors...

The present work analyses the wind load effects on 516 Arouca bridge, world's longest pedestrian suspension bridge in 2020. Computational fluid dynamics (CFD) was used to model a range of angles attack between −8° and +8°. simulations were performed by solving steady-state Reynolds averaged Navier-Stokes (RANS) equations with k-ω shear stress transport (SST) model. domain size analysed comparin...

Purpose. In the mouse model of oxygen-induced retinopathy (OIR), somatostatin-14 (SRIF) acting at the SRIF receptor subtype 2 (sst(2)) inhibits angiogenic responses to hypoxia through a downregulation of vascular endothelial growth factor. Information about where SRIF-sst(2) interactions take place is lacking, and downstream effectors mediating SRIF-sst(2) antiangiogenic actions are unknown. Me...

Turbulent flow separation coupling heat transfer with the solid case in the high area ratio rocket nozzle is simulated with the CFD method and the results are investigated experimentally. The finite volume method, the 2nd order upwind scheme, SST k-ω turbulence model and enhanced wall function are employed to solve the N-S equation and thermal conduction equation. To predict the fluid field and...

The goal of this research is to improve and validate a Reynolds Averaged Navier–Stokes (RANS) turbulence model perform accurate Computational Fluid Dynamics (CFD) simulations the urban wind flow. k-ω SST selected for calibration since its blended formulation holds remarkable optimization potential has increased relevancy in recent studies field. A simulation-based approach recalibrates closure ...

The Segment Stretch Transformation (SST) is an algorithm that transforms parallel Fork-Join (FJ) tasks into sequential tasks on multiprocessor systems when possible, in order to increase the schedulability of the tasksets of this model. SST is based on Task Stretch Transformation (TST) which is a transformation for the same model of tasks, but it uses segment migrations while SST eliminates the...

The influence of cloud radiative feedback, remote ENSO heat flux forcing, and oceanic entrainment on persisting North Pacific sea surface temperature (SST) anomalies is investigated using a stochastically forced ocean mixed layer model. The stochastic heat flux is estimated from an atmospheric general circulation model, the seasonally varying radiative feedback parameter and remote ENSO forcing...
