TL;DR: In this paper, an experimental set up specially designed for the investigation of drying kinetics, of heat transfer coefficient evolution, and of the mechanical torque necessary for stirring was presented, which was applied to municipal sewage sludge.
Abstract: Whereas indirect agitated drying has been extensively studied for granular materials, little is known in the case of pasty products. We describe an experimental set up specially designed for the investigation of drying kinetics, of heat transfer coefficient evolution, and of the mechanical torque necessary for stirring. This device was applied to municipal sewage sludge. Preliminary experiments were performed to investigate the influence of ageing of sludge on the drying kinetics. It appears that ageing does have no effect except for the first two days. The influences of the wall temperature, the stirrer speed, the dryer load and the location of the stirrer against the heated wall were studied. Three different rheological behaviors were observed during sludge drying. In particular, the sludge goes through a “glue” phase, and high levels of mechanical strain are recorded when the compact mass begins to break up. A critical stirrer speed is found within the range 40–60 rpm. To shorten the drying ti...

TL;DR: In this paper, the authors used a 1D unsteady hydraulic model (HEC-RAS) with lateral inflows provided by the hydro(geo)logical model Eau-Dyssee to explore a wide spectrum of river geometry scenarios, regarding river bed slopes and cross-sectional shapes.

TL;DR: This paper presents robust visual speed limit signs detection and recognition systems for American and European signs, both variants of the same modular traffic signs recognition architecture, with a sign detection step based only on shape-detection, which makes them insensitive to color variability and quite robust to illumination variations.
Abstract: In this paper, we present robust visual speed limit signs detection and recognition systems for American and European signs. Both are variants of the same modular traffic signs recognition architecture, with a sign detection step based only on shape-detection (rectangles or circles), which makes our systems insensitive to color variability and quite robust to illumination variations. Instead of a global recognition, our system classifies (or rejects) the speed-limit sign candidates by segmenting potential digits inside them, and then applying a neural network digit recognition. This helps handling global sign variability, as long as digits are properly recognized. The global sign detection rate is around 90% for both (standard) U.S. and E.U. speed limit signs, with a misclassification rate below 1%, and not a single validated false alarm in >150 minutes of recorded videos. The system processes in real-time videos with images of 640times480 pixels, at ~20 frames/s on a standard 2.13 GHz dual-core laptop.

TL;DR: In this paper, the interaction between oxides formed on a work roll grade and the coefficient of friction established with a strip steel usually rolled by this roll grade was studied. But the authors focused on the formation and growth of the oxide scale.

TL;DR: In this paper, a formulation of in-plane geometrical moire and grid methods with the vocabulary of signal processing is presented, and some consequences of the zoom-in effect induced by the moire phenomenon are given.
Abstract: This presentation is a formulation of moire and grid methods with the vocabulary of signal processing. It addresses basically the case of in-plane geometrical moire, but, as is well known, any geometrical moire setup can be related to in-plane moire. We show that the moire phenomenon is not a measurement method by itself, but only a step in a process of information transmission by spatial frequency modulation. The distortion of a grid bonded onto the surface of a loaded specimen or structure will cause locally a modulation (Delta) F of the spatial frequency vector F of the grid. The modulation (Delta) F is linearly related to the strain and rotation tensors. An equivalent point of view is to consider the same phenomenon as a phase modulation, caused by the inverse displacements. In this approach, moire is presented merely as an analog means of frequency substraction. The interpretation of the classical fringe processing techniques -- temporal and spatial phase shifting, Fourier transform method -- is made, and some consequences of the zoom-in effect induced by the moire phenomenon are given.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
