Seismic imaging faces challenges due to the presence of several uncertainty sources. Uncertainties exist in data measurements, source positioning, and subsurface geophysical properties. Reverse time migration (RTM) is a high-resolution depth approach useful for extracting information such as reservoir localization boundaries. RTM, however, time-consuming data-intensive it requires computing twi...

Thick composite laminates can be used in aerospace and automotive industry replacing metals for weight saving. Increasing the thickness can bring more defects, like voids. This master thesis focuses on the multi-scale voids prediction and their mechanical effect simulation of thick composite laminates manufacturing by Resin Transfer Molding (RTM). It could be potentially used in safe design of ...

The mechanical properties and quality of the RTM resin products depends highly on the complete filling and curing of resins in the mold. Hence, a method for monitoring the filling and curing of resins in mold has been a challenging problem in the field of RTM fabrication for a long time, particularly for thick components. In this paper, we describe a promising online method to monitor the flow ...

BACKGROUND Tinnitus is an increasingly serious problem for health care systems. According to epidemiological data, 7-14 % of outpatients have asked their physician about tinnitus and management strategies. Integrative outpatient treatments are currently regarded as promising therapeutic approaches for managing tinnitus. In this article we report on the treatment success of an outpatient tinnitu...

The Transactional Memory (TM) paradigm aims at simplifying the development of concurrent applications by means of the familiar abstraction of atomic transaction. After a decade of intense research, hardware implementations of TM have recently entered the domain of mainstream computing thanks to Intel’s decision to integrate TM support, codenamed RTM (Reduced Transactional Memory), in their last...

With the aim of optimization, numerical simulations of the cooling and vacuum systems of a compact 12 MeV race-track microtron (RTM) which is under construction at the Technical University of Catalonia have been carried out. The hydraulic and thermal performance of the cooling system for various flow rates has been studied using the Computational Fluid Dynamics (CFD) software. A CFD model, prev...

ABSTRACT Anisotropic pseudo-acoustic forward modeling and migration imaging are critical for high-precision seismic exploration. However, the wavefields simulated by traditional coupled anisotropic acoustic wave equation have problems of shear noise numerical simulation instability epsilon that is less than delta. Furthermore, although pure expressed differential operators can solve aforementio...

Reverse time migration (RTM) is the method of choice for imaging complex subsurface structures. In this paper, we show that slightly modifying the conventional formulation, plus implementing an appropriate imaging condition, yields a true amplitude version of RTM that provides the correct amplitude-versus-angle relation. We also discuss different ways to suppress the migration artifacts and sho...

With the current trend towards Building Information Model (BIM), facility managers have a new tool for raising efficiency. This paper discusses the integration of the BIM software with a real-time monitoring (RTM) system, as a 4D+ dimension in BIM, to track the electrical usage at every location in a building. This ability could be invaluable in identifying what unnecessary loads are connected ...

Situation awareness and geographic information systems in dynamic spatial systems such as road traffic management (RTM) aim to detect and predict critical situations on the basis of relations between entities. Such relations are described by qualitative calculi, each of them focusing on a certain aspect (e. g., topology). Since these calculi are defined isolated from each other, dependencies be...
