Повний текст джерелаFollowing an initial vegetable oil extraction through oilseed pressing, valuable residual oil persists within the oilseed cake, necessitating a further solvent extraction process. Hexane is currently the predominant solvent employed industrially for oilseed oil extraction. Despite its favourable characteristics such as lipid selectivity and ease of separation from oil through distillation, concerns regarding toxicity and non-renewable sourcing have prompted investigations into its replacement. This research aims to identify novel solvents for the selective extraction of oil from oilseeds that are healthier, safer, and environmentally sustainable, including bio-based solvents.To achieve this objective, a reverse engineering approach based on High Throughput Screening (HTS) and Computer Aided Molecular Design (CAMD) is employed to design optimal alternatives tailored to specific application requirements. The reverse engineering process began by defining the target values for key physicochemical properties (e.g., boiling point, flash point) of existing solvents used in oil extraction. Subsequently, molecular structures aligning with these targets were sought among thousands of solvents using the CAMD tool IBSS (InBioSynSolv). Specifically, for each and every molecule, the properties are predicted through group contribution models and compared against technical specifications, safety criteria, and environmental and health considerations. Further refinement of the candidate solvents generated by IBSS involved investigating the affinity between the identified solvent candidates and the target solutes within the cake, by comparing their σ-profile (determined using the COSMO-RS tool) and calculating the thermodynamic equilibrium. This methodology, coupling various modelling tools and industrial criteria, enabled an effective selection of a handful of candidates based on their selectivity towards lipids. Finally, experimental validation was conducted across various scales to corroborate the efficiency of the alternative solvents

Повний текст джерелаThis thesis discuss of the use of immersive environments of Virtual Reality (VR) for Computer Aided Design (CAD). We study how these new interfaces between man and information systems can improve the different tasks of geometric shape design that are actually done on workstation with screen. These workstations essentially use keyboard, mouse and graphical interface. However this kind of interaction does not take advantage of VR possibilities in term of direct 3d interaction. In addition, CAD objects does not allow ways to modify there shape with a direct and 3d interaction. We present an approach of reactive objects that allows changing the value of operations parameters in the construction history graph of the solid, from direct interaction of the user on the elements (vertex, edge, face) of the B-Rep of the solid. To this purpose, we use an inference system that decides what parameters to modify knowing the selected element, and how to map the manipulations of the user to numerical changes of the parameters. These inferences are based on sets of rules dealing with construction information attached to the elements of B-Rep. This model of reactive objects has been implemented in a software prototype allowing creation and modification of CAD objects in an intuitive way. The interface proposed is a multimodal and immersive environment. We also propose in this thesis a method for collision detection dedicated to immersive interaction and a graphic rendering system on PC cluster adapted to deformable objects

Повний текст джерелаSince their discovery, protein-protein interactions (PPIs) have been at the heart of many biological processes. These PPIs can be drug targets, either by mimicking a defective interaction or by inhibiting an inadequate interaction. Among the most implicated PPIs in pathologies, we found the Inhibitor Apoptosis Proteins (AAPs). These members are considered as key regulators of programmed cell death and, within the cell signalling pathways, XIAP, a member of the IAP family, is one of the most targeted proteins actually. Its involvement in cancers and rare inflammatory diseases makes it a therapeutic target of choice. Recent data in the literature have highlighted the importance of designing selective disruptors for this protein in order to avoid serious adverse effects. For this reason, it is essential to know the essential structural elements associated with the different domains of this protein, which distinguish it from other similar members of the IAP family. It is also essential to know the interaction mechanisms in which XIAP is involved with its partners. CADD tools, in particular the Structure-based drug design approach, as well as experimental evaluation techniques using fluorescence anisotropy (FPA) or AlphaScreen® technology were used as part of this thesis work. The results of in silico and in vitro work led to rational design proposals of selective small molecules that could potentially disrupt XIAP-mediated PPIs

Повний текст джерелаRNA molecules have recently gained huge relevance as therapeutic targets. The direct targeting of RNA with small molecule drugs emerges for its wide applicability to different classes of RNAs. Despite this potential, the field is still in its infancy and the number of available RNA-targeted drugs remains limited. A major challenge is constituted by the highly flexible and elusive nature of the RNA targets. Nonetheless, RNA flexibility also presents unique opportunities that could be leveraged to enhance the efficacy and selectivity of newly designed therapeutic agents. To this end, computer-aided drug design techniques emerge as a natural and comprehensive approach. However, existing tools do not fully account for the flexibility of the RNA. The project of this PhD work aims to build a computational framework toward the rational design of compounds targeting RNA. The first essential step for any structure-based approach is the analysis of the available structural knowledge. However, a comprehensive, curated, and regularly updated repository for the scientific community was lacking. To fill this gap, I curated the creation of HARIBOSS ("Harnessing RIBOnucleic acid - Small molecule Structures"), a database of all the experimentally-determined structures of RNA-small molecule complexes retrieved from the PDB database. HARIBOSS is available via a dedicated web interface (https://hariboss.pasteur.cloud), and is regularly updated with all the structures resolved by X-ray, NMR, and cryo-EM, in which ligands with drug-like properties interact with RNA molecules. Each HARIBOSS entry is annotated with physico-chemical properties of ligands and RNA pockets. HARIBOSS repository, constantly updated, will facilitate the exploration of drug-like compounds known to bind RNA, the analysis of ligands and pockets properties and, ultimately, the development of in silico strategies to identify RNA-targeting small molecules. In coincidence of its release, it was possible to highlight that the majority of RNA binding pockets are unsuitable for interactions with drug-like molecules, attributed to the lower hydrophobicity and increased solvent exposure compared to protein binding sites. However, this emerges from a static depiction of RNA, which may not fully capture their interaction mechanisms with small molecules. In a broader perspective, it was necessary to introduce more advanced computational techniques for an effective accounting of RNA flexibility in the characterization of potential binding sites. In this direction, I implemented SHAMAN, a computational technique to identify potential small-molecule binding sites in RNA structural ensembles. SHAMAN enables the exploration of the target RNA conformational landscape through atomistic molecular dynamics. Simultaneously, it efficiently identifies RNA pockets using small probe compounds whose exploration of the RNA surface is accelerated by enhanced-sampling techniques. In a benchmark encompassing diverse large, structured riboswitches as well as small, flexible viral RNAs, SHAMAN accurately located experimentally resolved pockets, ranking them as preferred probe hotspots. Notably, SHAMAN accuracy was superior to other tools working on static RNA structures in the realistic drug discovery scenario where only apo structures of the target are available. This establishes SHAMAN as a robust platform for future drug design endeavors targeting RNA with small molecules, especially considering its potential applicability in virtual screening campaigns. Overall, my research contributed to enhance our understanding and utilization of RNA as a target for small molecule drugs, paving the way for more effective drug design strategies in this evolving field

Повний текст джерелаActually Mechanical design use a computer Aided to optimise the time, the cost and performance of product for manufacturing. This study treats the problem of Mechanical design in general, but based on a concrete case already studied. The bibliography shows that indeed a space enough separates the general ideas of theoretical of the concrete aspects of the mechanical design. More particularly, four design projects of power transmission by Gear or bet has been considered. Projects have been developed in the environment CATIA, the conditions and the behaviour has been also extracted. The third part of this thesis is consisted to extrapolate the result and the method acquired to an industrial case of drilling moult-head gear box/design. Always in CATIA environrnent, many solutions have been proposed by repressing a large number of geometrical conditions. In summary, the observation and the realisation of significant mechanical cases have allowed to reduce the distance a between the application and the theory. The treated cases have been presented in order to that could serve also in the framework of the Primeca

Повний текст джерелаExpertise of CAD (computer aided design) software and AI (artificial intelligence) techniques are often associated for problems resolution in many domains. Nowadays, CAD software must give the user real assistance and be able to reason. Here, we present the most important CAD system functionalities and possible used methods. Constraint problems presentation in various domains shows that their resolution can be achieved by CAD software. We will particularly discuss problems of mechanical component design, task scheduling or space planning. First we are interested in geometric and topologic constraints management during mechanical part design and more particularly in comparison of CAD models with graph normalization. This comparison allows during design, the re-use in full or in part of existing parts or extracted parts from libraries. Two methods (one algorithmic, the other using CSP formalism) are presented and allow comparison of CAD models by graph normalization. After, we are interrested in a more particular constraint type : functional constraints. A special space planning problem is considered : integreted kitchen design. Modelling and resolution methods are presented

Повний текст джерелаModelling represents a large part of CAD/CAM systems. The work presented in this thesis is concerned with product modelling and consists in proposing a form feature-based design system. This system has main functions : features insertion in the designed part and their management all along the product evolution (modification, removal. . . ) ; creation of user-defined generic features and their insertion in the form feature library. A data structure able to model form features is presented first. Then a modification management method in the design model is proposed ; it avoids re-evaluating the whole design history. Finally, interactive and convivial tools allow the user to integrate new features into the software. The last part is concerned with the computer implementation of these proposals

Повний текст джерелаThe growth of consumer embedded devices, where digital, analog and software components are often combined together on a single chip, results in an increase of complexity of the design and verification processes. The validation of such analog and mixed-signal systems largely relies on simulation-based techniques combined with often ad-hoc analysis methods. This thesis is motivated by exportation of property-based formai techniques to the validation of analog and mixed-signal systems, at their continuous and timed levels of abstraction. Since the formai verification of non-trivial continuous systems remains very difficult, we resort to a lighter validation technique, that is, property-based monitoring. We define signal temporallogic STL as a high-Ievel specification language that allows expressing temporal properties of continuous and timed signais. STL is as an extension of the realtime metric interval temporallogic MITL, where continuous signais are transformed into Boolean ones using numerical predicates, and the temporal relations between them are expressed using standard real-time temporal operators whose atomic propositions correspond to those predicates. We develop two monitoring procedures, offline and incremental, for checking the correctness of simulation traces with respect to STL properties and implement them into a stand alone analog monitoring tool (AMT). The property¬ based monitoring framework is applied, using the AMT tool, to two real-world case studies, considering properties of a FLASH memory cell and a DDR2 memory interface. We also consider the problem of property-based formai verification of timed systems, and develop a modular translation from MITL formulae with past and future operators to timed automata. The construction that we propose is based on temporal testers, a special class of input/output timed automata that realize the sequential functions defined by the semantics of MITL operators. We first show how every MITL formula can be expressed using six basic temporal operators (three for past and three for future) and show how to build a temporal tester for each of these operators. Temporal testers for arbitrary MITL formulae are obtained by composing these elementary testers. Finally, we develop a procedure for automatic synthesis of controllers from high-Ievel specifications expressed in the bounded fragment of metric temporallogic (MTL). We propose a translation from properties specified in this real-time logic and under bounded variability assumption, into deterministic timed automata to which we apply safety synthesis algorithms to build a controller that satisfies the specification by construction

Повний текст джерелаThe design capitalization becomes a important element for collaborative work since this one comprises individual episodes. It passes by the conservation of the design reasoning and intentions traces. To this end, the individual designer needs to be assisted by a system which we called design intent system. The ideal of such a system was subdivided in modules and described. We were interested particularly to the CAD systems, which we want to compare with this ideal system. To arrive there, we undertook to analyze a design sequence using CAD tools. We adopted the protocol analysis method, where the designer verbalizes his thoughts in the course, or after his work (Concurrent Think Aloud or CTA, Retrospective Think Aloud or RTA). Four design experiments were thus carried out with the participation of four different designers. The CTA analysis enabled us to better understand the design using CAD tools and to propose a activities model. This model have six elements: observation, design intents formalization, design reasoning, representation intents formalization, reasoning for the representation and action. The links between the elements are represented in the model. A comparison between the CTA and the RTA was then carried out. This comparison allowed to detect some insufficiencies of CAD tool, used for the design intents representation. To contribute to mitigate these insufficiencies, we proposed a framework, which allowed to attach the design intents to the product CAD model

Повний текст джерела[The aim of that thesis is to show the benefits of integrated expert systems in Computer Aided Dwellin Design (CADD) systems. Design is an intricate ill-strcutrure problem. So, because of that complexity, rhe designers organise tehmselves and th design process in oreder to fnd what HA SIMON told the « Satisfectum » : a ssatisficing solution to design problem but not an optimum. But actually the CADD systems are lilited to the representation (calculation, lay outs, …) of the project under design. By integrating expert systems, CADD system will get a king of « intelligence » and will have a better understanding of the users needs. In order to verify that idea, a new CADD system has been built : X2A-SE. It incudes two kinds of expert systems : - deductive on « intelligent » interfaces between designers and classical CADD tools, - heuristic evaluation tools for aproximated calculations. These expert systems have been intregated to a classical CADD system. But they can also work alone out of that system. In our work we have developped the thermal design components of those tolls. ]

Повний текст джерелаThe so-called “Computer Aided Appearance Design” (CA²D), which emerged in the late 1990s, is a branch of CAD dealing specifically with the appearance of materials.CA²D could be a key tool for decision-making in the design phases of manufactured products. However, while nowadays the digital model has almost completely superseded the physical model as far as the choice of shape is concerned, the determination of colours and materials still essentially requires the production of one or more real prototypes. This research workraises the issues of decision-making related to appearance on the basis of a computer-generated image simulation. This pragmatic approach allowing a link between real and virtual provides in this field a new concept that we shall call iso-photographic rendering

Повний текст джерелаThis work is related with the automatic inspection of manufactured parts by using the CAD model of the part and the cloud of 3D points obtained by the digitization of the part with a range sensor. Initially we determine and model the parameters which influence the accuracy of the range sensor in the digitalization of a part. This model is used to produce automatically a sensing plan in order to acquire completely and precisely the geometry of a surface or of a complete part. A sensing plan consists of a set of viewpoints which defined the exact position and orientation of the camera relative to the part and other digitizatioin parameters. The goal of the sensing plan is to improve the accuracy of the depth measurement in order to be able to use the cloud of 3D points in inspection tasks. The requirements of the system are the exact position and orientation of the part and its CAD model in IGES format. There is no limitation in the geometry of the part to be digitized, hence simple / complex parts can be scanned. After registration between the 3D data and the CAD model, the cloud is segmented. The segmentation is fulfiled by computing the minimal distance from the 3D point to the surfaces (of the CAD model) and comparing some local geometric properties of the 3D point with the closest one on the surfaces. Segementation results are used to check dimensional and geometric tolerances of the part. By using the model of the noise we have introduced a dispersion value on each 3D point acquired by the range sensor. This value of dispersion is presented as a weight factor in the results of the dispersion

D (Computer Aided-Design) tools which are necessary for it and their complexity, we present in this thesis two algorithms of channel routing with two levels of technology. These algorithms use some concepts of operational Research. In fact, the first one is based on graphs optimization and the second on stochastic optimization by simulated annealing. Some applications (partition, placement and global routing) of simulated annealing to the physical design of systems are also described. Generally, these methods have allowed us to reduce the number of tracks (which are necessary for the interconnections) in comparison with the classical ones

Повний текст джерелаOur research project focuses on information management continuity along a building's life cycle. Our proposed solution is to enable partners of a construction project to share all the technical data produced and handled, during the building production process by building an information system through the use of internet technology. The system links distributed databases and allows building partners to access remotely and manage specific information. It provides an updated building representation that is being enriched and refined all along the design process stages. We focus more widely on data access through the help of adaptable interfaces. These interfaces are built dynamically based on a user profile and the current stage of the building's life cycle. Our work has been focused on the building product model. It aims to : ensure data exchange between distant partners, be able to share a common description diagram in a DBMS environment, Manipulate heterogeneous documents (texts, drawings, multimedia files, etc. ) , ensure professional approaches on a specific industrial product, help the users by developing decision support systems
