Background: Heat stress in the steel industry is considered as a serious threat to the health and safety of workers. A wide spectrum of complications and diseases from mild disorders such as burning sensation to fatal conditions such as thermal shock may occur due to uncontrolled thermal stress. In this study, heat stress assessment was performed according to the wet-bulb globe temperature (WBG...

This paper describes the online analysis of simulation data in real time using the Crew Activity Tracking System (CATS). CATS compares actual operator actions to a model of nominal operator procedures to track operator activities and detect possible operator errors. A suite of system state visualization tools, together with CATS, enables researchers to detect problematic operator-automation int...

We introduce a new concept of general $G$-$eta$-monotone operator generalizing the general $(H,eta)$-monotone operator cite{arvar2, arvar1}, general $H-$ monotone operator cite{xiahuang} in Banach spaces, and also generalizing $G$-$eta$-monotone operator cite{zhang}, $(A, eta)$-monotone operator cite{verma2}, $A$-monotone operator cite{verma0}, $(H, eta)$-monotone operator cite{fanghuang}...

Determining operator functional state is a critical component of adaptively aiding closed human-in-the-loop systems. The input measures or features used to define the operator functional state (OFS) model must be free of artifacts to ensure accurate classification of operator functional state. Electroencephalography (EEG) is a major component of the OFS model. Since the EEG magnitude is small r...

A recently conjectured microscopic realization of the dS4/CFT3 correspondence relating Vasiliev’s higher-spin gravity on dS4 to a Euclidean Sp(N) CFT3 is used to illuminate some previously inaccessible aspects of the dS/CFT dictionary. In particular it is argued that states of the boundary CFT3 on S 2 are holographically dual to bulk states on geodesically complete, spacelike R3 slices which te...

A cloud-based data stream management system (DSMS) handles fast data by utilizing the massively parallel processing capabilities of the underlying platform. An important property of such a DSMS is elasticity, meaning that nodes can be dynamically added to or removed from an application to match the latter’s workload, which may fluctuate in an unpredictable manner. For an application involving s...
