Evaluating Real-Time Forecasts in Real-Time [PDF]

open access: yesSSRN Electronic Journal, 2007
The accuracy of real-time forecasts of macroeconomic variables that are subject to revisions may crucially depend on the choice of data used to compare the forecasts against. We put forward a flexible time - varying parameter regression framework to obtain early estimates of the final value of macroeconomic variables based upon the initial data release

Measurements of Bicarbonate in Water Containing Ocean-Level Sulfate Using a Simple Multi-Pass Optical Raman System

open access: yesOceans, 2021
The concentration of dissolved inorganic carbon in the oceans at depths of a few meters to thousands of meters is a critical parameter for understanding global warming. The concentration is both pH dependent and depth dependent.

Improved Conflict Detection for Graph Transformation with Attributes [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
In graph transformation, a conflict describes a situation where two alternative transformations cannot be arbitrarily serialized. When enriching graphs with attributes, existing conflict detection techniques typically report a conflict whenever at least ...

REAL-TIME ECONOMETRICS [PDF]

open access: yesEconometric Theory, 2004
This paper considers the problems facing decision makers using econometric models in real time. It identifies the key stages involved and highlights the role of automated systems in reducing the effect of data snooping. It sets out many choices that researchers face in construction of automated systems and discusses some of the possible ways ...

Real-time specifications [PDF]

open access: yesInternational Journal on Software Tools for Technology Transfer, 2013
A specification theory combines notions of specifications and implementations with a satisfaction relation, a refinement relation, and a set of operators supporting stepwise design. We develop a specification framework for real-time systems using Timed I/O Automata as the specification formalism, with the semantics expressed in terms of Timed I/O ...

Drug Content Uniformity: Quantifying Loratadine in Tablets Using a Created Raman Excipient Spectrum

open access: yesPharmaceutics, 2021
Raman spectroscopy has proven valuable for determining the composition of manufactured drug products, as well as identifying counterfeit drugs. Here we present a simple method to determine the active pharmaceutical ingredient (API) mass percent in a ...

Non-Blocking Synchronization Between Real-Time and Non-Real-Time Applications

open access: yesIEEE Access, 2020
Real-time systems where applications with timing requirements coexist with applications without timing constraints are increasingly common. Furthermore, the processors used in desktops, smart phones or embedded devices are mostly multi-core, allowing the
