Le château de Lauzun (Lot-et-Garonne), évolution de la partie résidentielle de la fin du XIIe au XVIIIe siècle
Authors: Faravel Sylvie , Sireix Christophe , Martin Christian
Published: August 2013

Attesté pour la première fois dans les textes en 1259, le château de Lauzun a fait l’objet de remaniements

incessants jusqu’à la fin du XIXe siècle. Resté de nombreuses années à l’abandon, il a fait l’objet d’importants travaux de restauration dans les années 1990 qui justifièrent trois opérations de sauvetage urgent successives, suivies par des observations ponctuelles. Le château actuel, implanté à la pointe d’un

promontoire de faible altitude orienté au nord-ouest, se compose d’une enceinte trapézoïdale d’époque moderne abritant à l’est une vaste basse-cour transformée en parc et à l’ouest d’un ensemble de corps de

bâtiments regroupé à la pointe de l’éperon rocheux. Les travaux de restauration se sont essentiellement

concentrés sur les corps de logis et leurs abords immédiats, mais des observations ont pu également

être faites dans le parc. Des études complémentaires ont été effectuées: relevés d’architecture et relevé

topographique général, prospection géophysique de la totalité du parc et analyse dendrochronologique

des charpentes conservées. L’intervention archéologique avait trois objectifs: observer l’état des vestiges avant restauration, mieux connaître l’organisation médiévale du château et enfin cerner l’évolution topochronologique du château. Globalement ces objectifs ont pu être atteints. Fouilles, sondages et observations

ponctuelles ont en particulier permis de retrouver le donjon médiéval et de restituer en partie l’évolution

des différents corps de logis. Certaines interrogations restent en suspens en raison du type même de l’intervention limitée au cadre strict des travaux de restauration et de réaménagement du site.

Une fouille préventive près de l’église Saint-Sernin de Toulouse a permis la découverte de l’ensemble inédit d’une maison canoniale adossée au bâtiment collectif de la maîtrise. Cette maison en terre, présentée indépendamment ici, est une construction assez simple malgré le statut de ses occupants et la qualité de ses aménagements intérieurs. Dans cet exemple, le pouvoir et l’origine aristocratique ne s’expriment pas au travers de l’architecture de la résidence.
L’église romane de Croute à Lasserrade (Gers) : un édifice inachevé de Gascogne centrale autour de 1125
Authors: Balagna Christophe
Published: August 2013

The Romanesque Sainte-Christine church of Croute, which was formerly dedicated to Saint-Barthelemy, is a little known building, both complex and interesting. If very few researchers focused on this building of disorderly appearance and modest outer aspect, the study of its architecture, through the remains of interior and exterior elevations, together with the analysis of its sculpted decoration, reveal a monument that can be compared to the great Romanesque buildings of the region. The study of the church of Croute also renews our knowledge concerning the position of the central part of Gascony in the field of religious commande during the Romanesque period and its decoration reveals a perfect knowledge of contemporary sculpted entities, the motives and images of which were disseminated by the artists themselves during their travels.

Determining the Calibration Life of Measuring Devices by Means of Parameter Deviation Function
Authors: Clinciu Ramona
Published: August 2013

The paper presents the results obtained by performing an experimental study on specific measuring devices - caliper rules. The study is aimed at determining the calibration life of the measuring devices as a function of the metrological reliability, due to the internal parameter deviation. The experimental study conducted is aimed at determining the calibration life of external caliper rules of 150 mm, with depth rod and with a resolution of 0.05 mm. The experimental data is represented by the measuring errors, obtained for the same nominal size. Data is grouped in samples produced at a certain interval of time, by measuring the same dimension with a set of caliper rules.
The conclusion which can be drawn from the research performed on the considered set of caliper rules is that the method for determining the calibration life based on parameter deviation can be used for establishing the appropriate moment for performing the calibration for a specific set of measuring devices. By performing the appropriate program in the case of a set of specific measuring devices, it is possible to test whether the values obtained for the calibration life in each case considered meet the requirements set in the appropriate standards. In the case presented in the paper, the pre-set calibration life proved to be earlier than necessary and the application of this method would reduce the entire costs of the appropriate operation.
Use of Ontological Classes in the Exploration of User Needs
Authors: Oriţǎ Adrian , Drăghici George , Beney Jean Luc
Published: August 2013

This paper provides a new perspective on the construction and use of ontology in the context of the life cycle of the product. All information related to system-product should be available within the PLM (Product Lifecycle Management) but especially in innovative design phase. Because of the complexity of the information and to increase the effectiveness of the conceptual design the use of ontology is required in a particular domain, the design of machine tools, as a means of representation and classification of knowledge. The ontology is used to define a common vocabulary, explicit, formalized and shared by a community of developers in order to share knowledge and increase the efficiency of the design process. On the other hand, the design process is strongly influenced by the clarity and precision of the analysis of customer needs. To design a product well, design teams needs to know what it is the designing, and what the end-users will expect from it. Quality Function Deployment (QFD) [1] is a systematic approach to design based on a close awareness of customer desires, coupled with the integration of the functional groups. This paper proposes a taxonomy of customer needs in the QFD method and a demonstration from our point of view through an Industrial application.

Published: August 2013

The flow structure inside a water basin that, serves as a water tank of a modeled washer system with an immersed coiled heater and air supply nozzle is investigated experimentally. To obtain the flow velocity field, particle image velocimetry is employed, and different view-point sections are analyzed. A large-scale vertical flow structure, which is attributed to the strong air jet flow enhancement, causes the development of a 3D mixing layer in the entire flow regime. Although a coiled heater can provide buoyancy to the working fluid, the bubbly flow structure significantly dominates this stage by supplying air from the bottom nozzles.

Authors: Chen He , Guo Rui , Su Na , Zhang Yue Hong , Liu Xuan Wen
Published: August 2013

Lateritic ore can be heated and deoxidized rapidly via microwave irradiation with activated carbon as deoxidizer. In this paper, we studied the reductive roasting behavior of carbon-containing lateritic ore in microwave field and the composition of products through different heating process with varying carbon content. The results show that the heating process of the lateritic ore is a thermally stable process. The reductive level of lateritic ore can be adjusted by changing the proportion of carbon powders and the heating time of microwave irradiation. During this reductive roasting process, the quality of the added carbon powders will make a great impact on the phase composition of the product and then affect the heating rate. The reductive calcite product mainly consists of magnetite and wastage. With the rising of the content of reducing agent, the reductive level of lateritic ore will increase, which cause Ni and a small quantity of Fe to be deoxidized and forms Ni-Fe alloy.

Published: August 2013

The phase composition of the AlNiMnFeSiZr system is analyzed as applied to heat resistant nikalines (aluminum alloys of a new generation based on Ni containing eutectic), which are strengthened by the Al3Zr (L12) nanoparticles. It is shown that the presence of iron and silicon considerably complicates the phase analysis when compared with the AN4Mts2 base alloy. Silicon strongly widens the crystallization range, which increases the tendency of the alloy to form hot cracks during casting. It is shown that economically doped nikaline AN2ZhMts substantially exceeds the most heat resistant cast aluminum alloys of the AM5 grade in the totality of its main characteristics (heat resistance and mechanical and production properties).
Heat Release Effect of Thermal Emission Coating on Concentrator Photovoltaic Module
Authors: Nishioka Kensuke , Ota Yasuyuki
Published: August 2013

A thermal emission layer was coated on the aluminum chassis of a concentrator photovoltaic (CPV) module. The cell temperature in the CPV mini-module with the white thermal emission coating was 3 - 5°C lower than that in the CPV mini-module without the thermal emission coating. The effect of the high-radiation layer was remarkable. In spite of the high emissivity of the black thermal emission coating, the effect of the black coating was not remarkable. This is because the scattered light from environment is absorbed by the black coating and the CPV mini-module is heated. The color of CPV is important and the white coating is better than the black coating.

Published: August 2013

Inconel alloy 690 which contains high chromium concentration, has replaced Inconel alloy 600 because of its high resistance of stress corrosion cracking (SCC). Inconel alloy 690 is an austenite nickel-based alloy and it has intergranular chromium carbide (M23C6). Alloy should be maintained to be nearly free from fretting wear, corrosion, and hydrogen brittleness for a several decades. Main factors controlling deterioration are initial chromium carbide size and their distribution along austenite grain boundary and chromium concentration distribution inside of grain. The precipitated carbide along grain boundary are modeled by KJMA(Kolmogorov-Johnson-Mehl-Avrami) equation. The model is based on the classical nucleation theory, and Cr diffusion controlled growth followed by coarsening. The distribution of the chromium concentration near grain boundary with time is based on diffusion of chromium. The simulated results are compared with the experiments from literatures to confirm the validity of model.

Authors: Li Yuan Chen , Liu Wei Qun
Published: August 2013

With the development of multimedia network, more and more real-time multimedia applications require a network capable of satisfying QoS constraints such as delay and delay-variation bound so that the messages reach each destination node at almost the same time within a certain specified time limit, and certain application also demand that different streams for each different destination node should reach with minimum cost under the constraints. Therefore, the delay and delay-variation constraint multicast routing problem is studied and a new strategy in core selection methods is proposed. The algorithm we propose guarantees that the delay from the source to any destination does not exceed a real-time constraint satisfying the delay-variation constraint under cost minimization. In addition, this core selection methods achieve a balance of optimizing cost and delay of the multicast tree. Simulation results show that the algorithm has low complexity and balances between the computational complexity and performance, it can also meet the requirements of real-time network communication.

Data acquisition and automatic control with high precision of microclimate parameters in phytotron becomes more and more important. In order to overcome the defects of conventional phytotron with complex layout and inconvenient maintenance, a new implementation scheme of monitoring system based on wireless sensor network for phytotron is presented in this paper. Different kinds of environmental parameters were collected by wireless node and sent to the monitoring center through wireless communication network, and then processed and controlled by the main controller collaborating with interactive interface equipment. Testing result shows that the monitoring system with friendly interface has advantages of high sensitivity, easy operation and flexible extension.

A method that the adaptive super-resolution reconstruction for Terahertz (THz) image based on the Markov random field (MRF) is proposed. The adaptive Gaussian weighting factor based on the Markov prior distribution is applied to the smoothness of the image edge. The gradient-based optimization converges to the optimal solution fast. It simulates the fact Terahertz image to verify the feasibility of the method comparing with the traditional maximum a posteriori (MAP) super-resolution algorithm. The experimental results show that the adaptive Gaussian weighting super-resolution algorithm not only has high super-resolution performance, but also can better maintain the image edge information and reduce the noise of restored images, and get an ideal THz image. An adaptive super-resolution reconstruction method can be used for Terahertz image reconstruction.

In a monocular video scene, in order to improve the efficiency of object tracking and counting under occlusion conditions. The article presents a scheme to automatically track and count people in a surveillance system. First, a modified Gaussian mixture model was employed to determine pedestrian objects from a static scene. To identify foreground objects by positions and sizes of foreground regions which were obtained. Moreover, the performance to track objects was improved by using the modified overlap tracker, the modified overlap tracker was used to analyze the centroid distance between neighboring objects and help object tracking and people counting in occlusion states of merging and splitting. On the experiments of tracking and counting people in three video sequences, the results show that the proposed method can improve the averaged detection ratio about 10% as compared to the conventional work.

Unmanned Aerial Vehicle (UAV) remote sensing technology has the real-time ability to obtain ground images at earthquake landslide area. It makes it possible to extract landslide disaster information, support emergency rescue and decrease losses at the first second after earthquake. However, UAV remote sensing is prone to produce images with big-slant-angle. Although it is not fit for object measuring by traditional photogrammetry, it is benefit for observing slope at a better angle and extracting slope characteristics quantitatively. In this research, we define UAV big-slant-angle data as side-look images for earthquake landslide, which is based on an UAV close range photogrammetry idea. Image recognition of earthquake landslide area and three dimensional measuring of slope features will be researched. First of all, a projection datum plane along slope normal will be simulated according to the terrain surface. Appropriate images will be selected by evaluating camera pose and landslide overlapping rate. Secondly, orthogonal rotation matrixes are used to do 3D datum transformation with big-rotation-angle. Settlement of collinearity equations considering big-slant-angle condition will be researched. On this basis, dependent relative orientation among image series will be done to construct a three dimensional side-look-image model. At last, landslide image recognition, slope terrain surface reconstruction and landslide feature measurement is considered to cover the contents of earthquake landslide information extraction. Structural features and combined features can be analyzed and calculated on this basis. A rigorous solution of forward intersection in close range photogrammetry with big-slant-angle will be researched. Slope feature geometry and its relationship among images are to be considered to make a credible characteristic matching thinking big-rotation-angle exists. It has potentiality to provide variety landslide information with higher geometrical precision for cartography and risk analysis of earthquake landslide.

Sea state conditions such as wind, wave and current vary in different ocean waters. Two similar offshore structures installed in two different ocean regions will yield different responses. Determining the transfer function of the structure is a system identification exercise that yields the structural response and behaviour given any sea state condition. The transfer function can be determined using available measured sea state data and structural response data. In this paper, a six-legged semisubmersible physical model is developed to a scale of 1:100 and is tested in a wave tank to measure its responses due to simulated random wave loads. The transfer functions of the semisubmersible model are then determined using the measured responses and the measured wave heights.
