Texte intégralRésumé :
Highly automated and autonomous vehicles become more and more widespread changing the classical way of testing and validation. Traditionally, the automotive industry has pursued testing rather in real-world or in pure virtual simulation environments. As a new possibility, mixed-reality testing has also appeared enabling an efficient combination of real and simulated elements of testing. Furthermore, vehicles from different OEMs will have a common interface to communicate with a test system. The paper presents a mixed-reality test framework for visualizing perception sensor feeds real-time in the Unity 3D game engine. Thereby, the digital twin of the tested vehicle and its environment are realized in the simulation. The communication between the sensors of the tested vehicle and the central computer running the test is realized via the standard SENSORIS interface. The paper outlines the hardware and software requirements towards such a system in detail. To show the viability of the system a vehicle in the loop test has been carried out.

Hsiao, Yu-Ching, Chen-Jung Chang et Jing-Jing Fang. « Quantitative Asymmetry Assessment between Virtual and Mixed Reality Planning for Orthognathic Surgery—A Retrospective Study ». Symmetry 13, no 9 (2 septembre 2021) : 1614. http://dx.doi.org/10.3390/sym13091614.
Texte intégralRésumé :
Orthognathic surgical planning compromises three clinical needs: occlusal balancing, symmetry, and harmony, which may result in multiple outcomes. Facial symmetry is the ultimate goal for patients and practitioners. Pure virtual planning and mixed reality planning were two innovative technologies in clinical practices compared to conventional model surgery used for decades. We proposed quantitative asymmetry assessment methods in both mandibular contour (in 2D) and a midface and mandible relationship in 3D. A computerized optimal symmetry plane, being the median plane, was applied in both planning methods. In the 3D asymmetry assessment between two planning methods, the deviation angle and deviation distance between midface and mandible were within 2° and 1.5 mm, respectively. There was no significant difference, except the symmetry index of the anterior deviation angle between the virtual and mixed reality planning in the 3D asymmetry assessment. In the mandible contour assessment, there was no significant difference between the virtual and mixed reality planning in asymmetry assessment in the frontal and frontal downward inclined views. Quantitative outcomes in 3D asymmetry indices showed that mixed reality planning was slightly more symmetric than virtual planning, with the opposite in 2D contouring.

Texte intégralRésumé :
The survey of social values associated with an unorthodox, liquid, elusive reality, where concepts such as the pure, the clear, and the perfect, have been overcome by the tensions of contemporary life, has led architectural dogma into a frank crisis for at least fifty years. Venturi was one of the first to reflect on this, associating it with a chromatic idea where gray settled on white or black. It was the end of the great stories of modern and already historic architecture. From then, the possibility that otherness, diversity, and difference were installed in the blurred spaces that architectural rationality had left without suture or closure.

Karlinsky, Nahum. « Revisiting Israel’s Mixed Cities Trope ». Journal of Urban History 47, no 5 (9 août 2021) : 1103–29. http://dx.doi.org/10.1177/00961442211029835.
Texte intégralRésumé :
This article offers a critical examination of the term mixed cities, concentrating mainly on its usage in Zionist and Israeli discourse. It posits that the term is uniquely reserved to denote Israel’s Jewish Arab urban spaces. Presented as bureaucratic and value-free, the term sharply contrasts with the anti-Arab reality of Israel’s mixed cities. The article traces the origin of the term to pre-State, Zionist discourse, which denounced Arab Jewish “mixing,” situating it between “pure” Zionist and “foreign” Palestinian Arab spaces. The article identifies four general forms of urban (anti-)mixing: pluralistic, racial, sovereign, and colonial. It locates Israel’s mixed cities within the latter two categories. Abandoning this ideologically charged trope and replacing it with Urban Studies concepts are proposed. The advantages of this perspective are demonstrated with a test-case analysis of Arab-Jewish cities in British Palestine (1918-1948) through the lens of Scott Bollens’s model for the study of ethno-national contested cities.

Petrick, Martin. « Incentive provision to farm workers in post-socialist settings : evidence from East Germany and North Kazakhstan ». International Food and Agribusiness Management Review 20, no 2 (8 mars 2017) : 239–56. http://dx.doi.org/10.22434/ifamr2016.0020.
Texte intégralRésumé :
This article explores the current practice of motivating agricultural workers in post-socialist settings. In addition, it attempts to evaluate the different wage systems observed in reality and better understand under which conditions they are reformed. It does so by contrasting the experience of two extreme cases representing fast and slow reform advance, East Germany and North Kazakhstan. The primary data for the analysis comes from cross-sectional farm surveys conducted by various researchers in both countries. East German farmers quickly replaced the inherited Soviet-style piece rate payment system by simple time rate schemes, augmented by wage premia for certain performance parameters, especially in livestock. To the contrary, the piece rate approach persists in many farms in North Kazakhstan. Moreover, the latter rarely use non-wage incentives to motivate their workers. In Kazakhstan, farms using either mixed systems or pure piece rates were more productive than the reference group using pure time rates. Labour cost per worker were lowest for pure time rate systems in both countries, followed by mixed bonus systems, whereas pure piece rate systems implied the highest cost in Kazakhstan. Kazakhstani managers tend to move away from the Soviet piece rate system if external investors become engaged in farming operations.

Mas, Albert, María Jesús Torija, María del Carmen García-Parrilla et Ana María Troncoso. « Acetic Acid Bacteria and the Production and Quality of Wine Vinegar ». Scientific World Journal 2014 (2014) : 1–6. http://dx.doi.org/10.1155/2014/394671.
Texte intégralRésumé :
The production of vinegar depends on an oxidation process that is mainly performed by acetic acid bacteria. Despite the different methods of vinegar production (more or less designated as either “fast” or “traditional”), the use of pure starter cultures remains far from being a reality. Uncontrolled mixed cultures are normally used, but this review proposes the use of controlled mixed cultures. The acetic acid bacteria species determine the quality of vinegar, although the final quality is a combined result of technological process, wood contact, and aging. This discussion centers on wine vinegar and evaluates the effects of these different processes on its chemical and sensory properties.

Texte intégralRésumé :
Pure forest stands are widely believed to be more prone to pest outbreaks and disease epidemics than mixed stands, leading to recommendations of using stand diversification as a means of controlling forest pests and pathogens. We review the existing evidence concerning the effects of stand tree-species diversity on pests and pathogens in forests of the boreal zone. Experimental data from published studies provide no overall support for the hypothesis that diversification of tree stands can prevent pest outbreaks and disease epidemics. Although beneficial effects of tree-species diversity on stand vulnerability are observed in some cases, in terms of reductions in damage, these effects are not consistent over time and space and seem to depend more on tree-species composition than on tree-species diversity per se. In addition, while mixed stands may reduce the densities of some specialized herbivores, they may be more attractive to generalist herbivores. Given that generalist mammalian herbivores cause considerable tree mortality during the early stages of stand establishment in boreal forests, the net effect of stand diversification on stand damage is unlikely to be positive.

"Literary Theory. Linguistics. Cultural Studies" Series, no 6 (2022) : 245–57. http://dx.doi.org/10.28995/2686-7249-2022-6-245-257.
Texte intégralRésumé :
The purpose of the article is to analyze the influence of Buddhism on the ideological component and poetics of A. Makushinsky’s novel “Max” and poetry books “The Light Behind the Trees” and “The Sea, Today”. In the novel “Max” the protagonist follows the path of spiritual transformation. The goal of this path is a state in which reality will be seen as it is – genuine, that is, empty, and not illusory, hidden behind matter and various forms. The image of the illusory reality generated by the affected human mind in the novel is associated with the motives of fuzziness, confusion, absence. Characters and items in “Max” have a phantom status. The hero approaches the desired state through the desire for a “fixed point”, for presence in the present time, for complete objectivity, for pure consciousness. The chronotope of the novel is conventional: the spatial loci of “Max” do not have clear boundaries and are similar to each other; the past, present and future are mixed and tend to a single point – hereand-now. In poetry books, as well as in the novel, there is, in the words of the author, «an intuition of the radiant emptiness». A. Makushinsky’s poems are meditative and are tuned to capture the emptiness and silence hidden behind the words and phenomena of reality.

Texte intégralRésumé :
<p><strong>Abstract.</strong> While extracting land cover from remote sensing images, each pixel in the image is allocated to one of the possible class. In reality different land covers within a pixel can be found due to continuum of variation in landscape and intrinsic mixed nature of most classes. Mixed pixels may not be appropriately processed by traditional image classifiers, which assume that pixels are pure. The existence of mixed pixels led to the development of several approaches for soft (often termed fuzzy in the remote sensing literature) classification in which each pixel is allocated to all classes in varying proportions. However, while the proportions of each land cover within each pixel may be predicted, the spatial location of each land cover within each pixel is not. Thus, it is important to develop and implement a classifier that can work as soft classifiers for landslide identification. This work is an attempt to document and identify landslide areas by five spectral indices using temporal multi-spectral images from IRS-P6 LISS-IV images. To improve the spectral properties of spectral indices for specific class identification (in this case landslide) a Class Based Sensor Independent (CBSI) technique proposed. The result indicates that CBSI based Transformed Normalized Difference Vegetation Index (TNDVI) temporal indices data gives better results for landslide identification with minimum entropy and membership range.</p>

Texte intégralRésumé :
Different approaches for modeling of precipitation in Al–Mg–Si alloys are reviewed. First of all, the importance of a precipitation modeling and its interrelations with other components in a process model are explained. Then the empirical, statistical, and physically based modeling, with each being a different modeling approach, are introduced. The Kampmann–Wagner numerical (KWN) model, which is a physically based finite difference method, is explained as a model that is able to capture simultaneous nucleation, growth, and coarsening reactions. The growth kinetics in the KWN model is based on the assumption of local equilibrium hypothesis, inferring that there is an immediate thermodynamic equilibrium as soon as two phases are in contact. This assumption implies the diffusion-controlled nature of the transformation. The other extreme approach is the assumption of interface-controlled growth, where the interface reaction (atom transport across the interface) controls the kinetics. In reality, neither of these scenarios can be absolutely true. A modified version of KWN model such that the growth can be treated with a mixed-mode nature (neither pure diffusion-controlled nor pure interface-controlled) is introduced. How the geometry of precipitates can be incorporated into the precipitation model is also explained.

Texte intégralRésumé :
In almost everything that we have discussed so far, we have assumed, explicitly or implicitly, either that the systems we are looking at are perfectly mixed or that they are not mixed at all. In the former case, concentrations are the same everywhere in the system, so that ordinary differential equations for the evolution of the concentrations in time provide an appropriate description for the system. There are no spatial variables; in terms of geometry, the system is effectively zero-dimensional. At the other extreme, we have unstirred systems. Here, concentrations can vary throughout the system, position is a key independent variable, and diffusion plays an essential role, leading to the development of waves and patterns. Geometrically, the system is three-dimensional, though for mathematical convenience, or because one length is very different from the other two, we may be able to approximate it as one- or two-dimensional. In reality, we hardly ever find either extreme—that of perfect mixing or that of pure, unmixed diffusion. In the laboratory, where experiments in beakers or CSTRs are typically stirred at hundreds of revolutions per minute, we shall see that there is overwhelming evidence that, even if efforts are made to improve the mixing efficiency, significant concentration gradients arise and persist. Increasing the stirring rate helps somewhat, but beyond about 2000 rpm, cavitation (the formation of stirring-induced bubbles in the solution) begins to set in. Even close to this limit, mixing is not perfect. In unstirred aqueous systems, as we have seen in Chapter 9, it is difficult to avoid convective mixing. Preventing small amounts of mechanically induced mixing requires considerable effort in isolating the system from external vibrations, even those caused by the occasional truck making a delivery to the laboratory stockroom. It is possible to suppress the effects of convection and mechanical motion in highly viscous media, such as the gels used in the experiments on Turing patterns as discussed in the previous chapter. There, we can finally study a pure reaction-diffusion system. Systems in nature—the oceans, the atmosphere, a living cell—are important examples in which chemical reactions with nonlinear kinetics occur under conditions of imperfect mixing.

Texte intégralRésumé :
Mapmakers typically depict the aridlands of the world in colors like buff and buckskin, in contrast to the greens of wetter regions. Their choice is true to reality, for dry places usually produce scant vegetation, and the bare ground, baked by unobstructed sun, tends to wear a washed-out shade of dun, or one of its cousins. In the North American Southwest, you might add a touch of rust to reflect the widespread iron-rich geology. In many areas, oxides of iron produce the pinkish flesh tones that make it easy to think the landscape is alive. If you also brush in some piney greens and spruce black for upland woods and forests, and dab smaller areas white to represent high-country snowcaps, you have a fair start toward capturing the palette of the region. But you would still be missing the most definitive color of the Southwest, which is found not beneath the feet, but overhead. You can look up, straight up, almost any day of the year, and there it is: an intense, infinite blue, miles deep and beyond reach. It is not merely bluish, not the watery blue of Scandinavian eyes, not the black-mixed blue of dark seas or bachelor buttons, not the hazy blue of glacier ice or distant mountains, but an Ur-blue, an über-blue, a defining quintessence. It is to other blues as brandy is to wine: a distillation, pure and heady. It can be a little deflating to reflect that the ethereal blue of southwestern skies results from mundane forces, that it is the product of solar radiation and atmospheric gases interacting in an environment shaped by climate. If the air held more water vapor, the sky would whiten overhead, as it does at the horizons, where the light that reaches our eyes has more atmosphere and diffusing vapor to travel through.

Texte intégralRésumé :
The treatment of Convective Heat Transfer Coefficients (CHTCs) in an enclosure has a significant impact on the thermal design of electronic appliance, especially the CHTCs in an enclosure with internal isolated blocks. The CHTCs of the isolated blocks for pure natural convection are usually used, while it may not be applicable to any practice. Combined convective heat transfer, even forced convective heat transfer, is sometime more applicable in reality. In our present work, first of all, validation of the turbulence model for CFD simulation of natural convective flows in a square enclosure is performed. The values of CHTCs for vertical walls obtained by using a low Reynolds k-ε model agree well with the existed correlations. The simulation also indicates that the distance from the first grid to the wall has a significant impact on the CHTCs. Using this low Reynolds k-ε model, computer simulations of natural and forced convective heat transfer within a square enclosure containing ten isolated blocks are performed. For both the natural and forced convection, the dimensionless Nusselt numbers are derived by the obtained results. For the case of mixed convection, the CHTCs are established by blending those for natural and forced convection using the Churchill-Usagi approach, which is a general expression combines the asymptotic solutions of independent CHTCs into the mixed convection by using a Churchill-Usagi blending coefficient.

Texte intégralRésumé :
Bi-material systems in which two dissimilar materials are adhesively joined by a thin adhesive interlayer have been widely used in a variety of modern industries and engineering structures. There are two fundamental issues that need to be adequately addressed: (1) Fracture of bonded bi-materials is mixed mode: Mode-I (pure peel) and Mode-II (pure shear). Fracture test implementation of bi-material systems with the traditional Mode-I methods will induce a noticeable mixed mode fracture due to the disrupted symmetry by the bi-material configuration; (2) The popular cohesive zone models (CZMs) for accurate fracture simulations require more than a single parameter (toughness) as is the case in the traditional linear elastic fracture mechanics (LEFM). Thus, J-integral is highly preferred. It can not only capture more accurate toughness value by considering the root rotation effect, but also facilitate the experimental characterizations of the interfacial cohesive laws, which naturally include all required parameters by CZMs. Motivated by these two important issues, a novel idea is proposed in the present work to realize and characterize the pure Mode-I nonlinear interface fracture between bonded dissimilar materials: Despite the approximation with the elementary beam theories, the accuracy is validated by numerical simulations. The proposed approach may be considered as a promising candidate for the future standard Mode-I test method of adhesively bonded dissimilar materials due to its obvious simplicity and accuracy.
