Ray, Simon. "The real-estate component in the production process of non-financial firms : investment, employment and mobility." Thesis, Aix-Marseille, 2016. http://www.theses.fr/2016AIXM2018.
Full textThis thesis studies channels through which corporate real-estate affects investment, employment and mobility of Non-Financial Corporations (NFCs). Real-estate assets account for a sizable share of firms' asset value and premises are often one of the main expenditure items of NFCs. Real-estate prices hence have a bearing on the value of firms' pledgeable assets and on the cost of inputs. In a frictional credit market, the firms' borrowing capacity can be enhanced by an increase in asset's value. The first two chapters of this thesis study this collateral channel and its effects on investment and employment. The first chapter proposes a dynamic setting with a focus on labor market variables whereas the second explores heterogeneous effects across firms, based on micro-data. The last chapter examines the consequences of the peculiarities of real-estate adjustment costs. Studying the relocation behaviour of firms facing varying moving costs, we document important effects of the costs associated with a change in the size of the premises on the employment dynamics

Full textAssembly/Disassembly (A/D) simulations are important to improve design and efficiency of product development processes. In order to get efficient simulation processes it is important to simulate all the possible relative movements between the components in a mechanical assembly. This is important both in the context of interactive simulation and in the context of immersive/real time simulations. If some categories of movements are missing, simulations can loose key configurations, hence they may be no longer meaningful. The scope in research, whiting this thesis deals, in the first time, with a theoretical approach for developing of a kinematical model able to represent all the valid relative movements of a reference component with respect to its surrounding ones, which form a family of trajectories. It is based on the analysis of the three basic movements: translation, rotation and helical ones. In order to determine the compatibility between different families of trajectories, a bi-quaternion is associated to each contact area between the different components. All possible trajectories for each component are analyzed, for the three basic type of movements, in order to find the compatible ones, which leads to the specification of an operator. Thus, the results of all the possible associations are determined and a general combination operator is proposed. The properties of this later are demonstrated as well. The operator can form, in a real time simulation environment, the basis for determining at each moment, the valid movements between components, thus reducing the complexity of collision detection algorithms. The A/D simulations can be performed either from an automated or interactive point of view using standard computer equipment or through immersive and real-time simulation schemes. In order to address this diversity of configurations, a simulation framework was developed. It is based on a new simulation preparation process which allows a simulation process to address up to two types of shape representations, i. E. B-Rep NURBS and polyhedral ones, at the same time, thus handling efficiently the configurations where 3D shape representations of assemblies play a key role. In order to illustrate the simulation process the automatic identification of contacts in a 3D product model and their corresponding list is described. After the identification stage, an interpretation of the results is needed in order to have the complete list with the mechanical contacts for a product. The preparation process is performed within three major stages : model tessellation, surface merging and contacts identification. The framework is based on STEP exchange format. This software environment can assist designers to achieve a satisfactory assembly analysis rapidly and can reduce the lead-time of product development. Further consequences of the present work is its ability to produce models and treatments that improve integration of assembly models in immersive environments taking into account of the haptic and visual models needed. Assembly/Disassembly simulations using haptic devices are facing difficulties while simulating insertion/extraction operations such as removing cylinders from holes for example. In order to address this configuration as well as others, an approach based on the kinematic model and on the simulation framework is proposed

Perrin, Rémi. "Characterization and design of high-switching speed capability of GaN power devices in a 3-phase inverter." Thesis, Lyon, 2017. http://www.theses.fr/2017LYSEI001/document.
Full textThe french industrial project MEGaN targets the development of power module based on GaN HEMT transistors. One of the industrial applications is the aeronautics field with a high-constraint on the galvanic isolation (>100 kV/s) and ambient temperature (200°C). The intent of this work is the power module block (3 phases inverter 650 V 30 A). The goal is to obtain a small footprint module, 30 cm2, with necessary functions such as gate driver, gate driver power supply, bulk capacitor and current phase sensor. This goal implies high efficiency as well as respect of the constraint of galvanic isolation with an optimized volume. This dissertation, besides the state of the art of power modules and especially the GaN HEMT ones, addressed a control signal isolation solution based on coreless transformers. Different prototypes based on coreless transformers were characterized and verified over 3000 hours in order to evaluate their robustness. The different studies realized the characterization of the different market available GaN HEMTs in order to mature a circuit simulation model for various converter topologies. In the collaborative work of the project, our contribution did not focus on the gate driver chip design even if experimental evaluation work was made, but a gate driver power supply strategy. The first gate driver isolated power supply design proposition focused on the low-voltage GaN HEMT conversion. The active-clamp Flyback topology allows to have the best trade-off between the GaN transistors and the isolation constraint of the transformer. Different transformer topolgies were experimentally performed and a novel PCB embedded transformer process was proposed with high-temperature capability. A lamination process was proposed for its cost-efficiency and for the reliability of the prototype (1000 H cycling test between - 55; + 200°C), with 88 % intrinsic efficiency. However, the transformer isolation capacitance was drastically reduced compared to the previous prototypes. 2 high-integrated gate driver power supply prototypes were designed with: GaN transistors (2.4 MHz, 2 W, 74 %, 6 cm2), and with a CMOS SOI dedicated chip (1.2 MHz, 2 W, 77 %, 8.5 cm2). In the last chapter, this dissertation presents an easily integrated solution for a phase current sensor based on the magnetoresistance component. The comparison between shunt resistor and magnetoresistance is experimentally performed. Finally, two inverter prototypes are presented, with one multi-level gate driver dedicated for GaN HEMT showing small switching loss performance

Full textThe research studies the internal dynamics of suburban territories through the analysis of micromobility related to the implementation of regional transport infrastructure. This paper aims at demonstrating the values of micromobility networks as an informative source of the sociospatial dynamics contained in the informal territory and as a component of urban qualifi cation. These networks bring crucial data to the metropolitan planning about its internal functioning and the potentialities of articulation with larger scales of mobility. Mobility as a spatial network, with its own density and impregnation capacity in the territory, becomes a physical tool of urban composition, giving access and generating polarity to build proximity networks and to foster the sense of identity by its users. The research deals with contemporary aspects of the ongoing transformations in suburban district Jardim Ângela in São Paulo, identifying the specifi c characteristics of this area at diff erent scales.

Full textDistances, commuting, private car, travel speeds… those are common words in traditional transport studies, which have tried for years to manage motorized mobility with one common goal: to facilitate movement and reduce travel times. But what happens with what’s been left out of this analysis? What happens with close distances mobility, with walking mobility, with the mobility needs of those without access to the motorized transports? This thesis aims to contribute to the knowledge of this left-out dynamics, and it does so from the perspective that this knowledge can help us achieve our true common goal for urban mobility: social and environmental sustainability. This thesis proposes a new methodology to measure close-scale urban dynamics through the observation of everyday mobility patterns in the City and the Metropolitan Region of Barcelona. By defining a proximity trip by a modal choice and a temporal variable, we are visualizing a specific kind of trip that appeared unreported to traditional analysis. As this thesis sets to demonstrate, this kind of proximity trips are highly common in a dense and Mediterranean city like Barcelona, and they represent an environmentally sustainable way of mobility that is available for all the inhabitants of the city. From that point of view, the present work sets to establish the conceptual basics that define what proximity is and to explore the academic literature in search of all the beneficial effects attributed to urban proximity. At the same time, the empirical work proposes four different study cases that seek to deepen our understanding of this kind of small-scale mobility. The target of this empirical study cases is to evaluate proximity utilization in the Municipality and Regional Area of Barcelona and to test its importance in people’s everyday lives, with the hope that proximity travelling can offer a viable and sustainable solution to the problems of our current transport system.

Full textIn the context of international mobility, we aim to explore in this thesis the motivations of the French executives regarding their intentions to accept an international assignment.Our study is based on the Theory of Planned Behavior (TPB) and enabled us to conclude that the intentions to accept international assignment does not depend solely on the attitudes. The perceived behavioral control also contribute to the determination of this intention. The theoretical contribution of our research is to apply the model of TPB on the French executives who have the intention to accept an international assignment. The managerial contribution is to offer the firms some key guidelines to broaden their understanding pertaining to the improvement in their practices of mobility by identifying the motivations of the executives for an international assignment.The methodological contribution is the proposition of scenarios based on country of destination for exhibiting the contribution of three determinants of this intention in terms of attitudes, social norms and perceived control
