Повний текст джерелаAn innovative cooking system based on infrared radiation (IR) using a CO2 laser (CO2 IR Laser) has been developed considering that water absorbance of electromagnetic infrared radiation at CO2 laser wavelength is very high. The new cooking system has been adapted into a 3D food printer and has been designed with the following requirements: 1) ability to cook in a delimited area; 2) control of the cooking temperature; 3) physical dimensions that fit inside the 3D Food Printer; 4) energy consumption below the power supply limits; 5) software-controlled system; 6) versatility to cook while printing the food or to cook once the food is printed. In the present study, two CO2 IR Laser cooking systems have been used and tested. The first CO2 IR Laser cooking system studied was a laser engraver and cutter equipment in which specific conditions were applied to cook beef burgers, mashed potatoes bites and pizza dough. After, a new cooking system adapted to the 3D food printer was developed, consisting of a CO2 laser lamp, a system of galvo mirrors that direct the laser beam to the cooking area, and a software that allowed controlling the position and the frequency of movement of galvanometers. With this new system, a chosen area could be homogenously cooked, due to the rapid movement of the galvo mirrors. The food products cooked inside the 3D food printer were: beef burgers; vegetarian patties prepared with legumes, vegetables and egg as main ingredients; and pizza dough. To demonstrate that cooking had been achieved, food products were cooked with the CO2 IR laser systems and different traditional cooking systems (flat and barbeque grills; IR, convection, desk and microwave ovens). Microbiological, physico-chemical and sensory characteristics of the cooked foods were evaluated. The formation of polycyclic aromatic hydrocarbons was analyzed in beef burgers and pizzas to evaluate toxicological safety, and the thermal effect in the count reduction or survival of Salmonella Typhimurium, Salmonella Senftenberg and Escherichia coli O157:H7 inoculated in beef burgers and vegetarian patties was studied. Microbiological and toxicological analyses showed that food products cooked with the new CO2 IR Laser system were as safe as food cooked with traditional methods. Sensory analyses showed that consumers had the same, or even higher, level of preference for foods cooked with CO2 IR laser system in comparison with foods cooked with traditional methods. In addition, a numerical model based on computational fluid dynamics was developed to simulate the cooking process of beef burgers and vegetarian patties, and it was validated with experimental data of temperature evolution during the cooking process. The numerical results for temperature evolution given by the model coincide with the experimental data, except for the first minutes of cooking. The numerical simulation model is a powerful tool to optimize the cooking process of the CO2 IR Laser system. Based on the results obtained, future work will be carried out including cooking experimental studies with foods containing a significantly different composition; the simulation of the cooking process with different parametric conditions; and nutritional studies.

Anemia affects about 25% of the world’s population and causes roughly 8% of all disability cases. The development of an affordable point-of-care (POC) device for detecting anemia could be a significant for individuals in underdeveloped countries trying to manage their anemia. The objective of this study was to design and fabricate a 3D printed, low cost microfluidic mixing chip that could be used for the diagnosis of anemia. Microfluidic mixing chips use capillary flow to move fluids without the aid of external power. With new developments in 3D printing technology, microfluidic devices can be fabricated quickly and inexpensively. This study designed and demonstrated a passive microfluidic mixing chip that used capillary force to mix blood and a hemoglobin detecting assay. A 3D computational fluid dynamic simulation model of the chip design showed 96% efficiency when mixing two fluids. The mixing chip was fabricated using a desktop 3D printer in one hour for less than $0.50. Blood samples used for the clinical validation were provided by The University of Kansas Medical Center Biospecimen Repository. During clinical validation, RGB (red, green, blue) values of the hemoglobin detection assay color change within the chip showed consistent and repeatable results, indicating the chip design works efficiently as a passive mixing device. The anemia detection assay tended to overestimate hemoglobin levels at lower values while underestimating them in higher values, showing the assay needs to go through more troubleshooting.

Повний текст джерелаProjektet går ut på att utvärdera hur väl en haptisk utrustning går att använda för att interagera med en visualisering av volumetrisk data. Eftersom haptikutrustningen krävde explicit beskrivna ytor, krävdes först en triangelgenerering utifrån den volymetriska datan. Algoritmen som används till detta är marching cubes. Trianglarna som producerades med hjälp av marching cubes skickas sedan vidare till den haptiska utrustningen för att kunna få gensvar i form av krafter för att utnyttja sig av känsel och inte bara syn. Eftersom marching cubes lämpas för en parallelisering användes OpenCL för att snabba upp algoritmen. Grafer i projektet visar hur denna algoritm exekveras upp emot 70 gånger snabbare när algoritmen körs som en kernel i OpenCL istället för ekvensiellt på CPUn. Tanken är att när vidareutveckling av projektet har gjorts i god mån, kan detta användas av läkarstuderande där övning av svåra snitt kan ske i en verklighetstrogen simulering innan samma ingrepp utförs på en individ.

Повний текст джерелаThroughout the time, in consequence of workstations and personal computers, the software and hardware takes focus at various research areas around the world due the possibility to reduce the size of computers and doesn't compromises the performance of applications. One of areas that takes advantage from it is Information Visualization due the fallen of costs of hardware components and the improving of graphics cards, the data visual analysis that could be done only in workstations, today, is possible uses the personal computers. Now days, such personal computers can be replaced by mobile devices, e.g., tablets and cellphones since the performance of those devices is equivalent or, in some cases, better than PCs. Thereby, the Information Visualization area can be explored in mobile devices allowing companies and research labs to analyses different types of data and various contexts and geographic location that they are. Working in this context fits in order to explore techniques of Information Visualization that use the main resources of mobile devices interactive and simple mode. We hope to support the analysis process and decision making of users. In this work we are going to presents three techniques of Information Visualization for analysis the multidimensional database in mobile device, since that each one of these will be exemplified in two distinct cases of study. One of this is part of Petrobras Project at UFRGS and the next in a Fatality Analysis Reporting System of railroads at US between 1975 and 2007.

Повний текст джерелаThe work of this thesis fit on the boundary between two complementary research areas: the field of 3D Virtual Environment (3DVE) from Computer Graphics (CG) and Virtual Reality (RV) and the field of Human-Computer Interaction (HCI). They rely on three assessments. Firstly, we observe that 3DVE takes more importance in our daily life (video games, serious games, e-commerce, museums, through the web and on mobile devices). Secondly, HCI becomes more complex with the emergence of advance forms of interaction like ambient computing, tangible interaction or spatial and gestural interactions. This evolution goes along with a diversification of devices (3D mouse, the Wiimote, the Kinect or the Leap Motion). Thirdly, the design of interaction techniques with 3DVE brings up some different considerations taken into account by the communities in the field of 3DVE and HCI. Therefore, take advantage of the latest considerations of EV3D communities (metaphors, quality of 3D interaction) and HCI (advance forms of interaction) results in the need to develop the coupling between advance forms of interaction techniques and EV3D. In this context, the objective of this thesis work is to contribute to the development of interactive 3D environments in multiple situations, including large audience situations. The approach we developed aimed to create a bridge between 3D and HCI design considerations. We intend to improve the coupling of advance interaction techniques with interactive 3D virtual environment. After analyzing methods for the design of interaction techniques for 3DVE, a first contribution consists in a design framework of 3D interaction. This framework aggregates design issues stem from 3D and HCI and help the designer to identify several elements involve in the coupling of interaction with a 3DVE. This design framework is based on the analysis of the links between user tasks and elements of the 3DVE impacted by these tasks. In order to precisely characterize each link, we have introduced the 3DIM (3D Interaction Modality) notation that describes the characteristics of the different elements constituting a "3D Interaction Modality" for the accomplishment of a user's interaction task in a 3DVE. We have grouped these elements into six blocks: the user, the physical actions, the physical objects, the input devices, the 3D behaviors and the 3D interactive objects. We complete our framework with analytical properties for guiding the designer and provide descriptive, evaluative and generative power at our conceptual model of advanced interaction techniques for 3DVE. Collaborating with the Museum of "Le Pic du Midi" observatory in France, we used our framework to design and implement tangible interaction and technique based on smartphone usage. Museum visitors can use these techniques in a 3DVE of the "Telescope Bernard Lyot" to explore and understand its functioning. We have conducted three users' studies in order to explore the design space of using a smartphone to interact with 3DVE. We used the smartphone in different ways to navigate, select and manipulate a 3D object displayed on a large remote screen. We explored several design solutions with a smartphone as a touch device, as a tangible object or mid-air interaction around the device

In the United States, 40% primary energy consumption comes from electricity generation, which is the fastest growing form of end-use energy. Industries such as commercial airlines are increasing their use of electric energy, while phasing out the mechanical and pneumatic aircraft components, as they offer better performance and lower cost. Thus, implementation of high efficiency, electrical system can reduce energy consumption, fuel consumption and carbon emissions [1]. As more systems rely on this electric power, the conversion from one level of power (voltage and current) to another, is critical. In the quest to develop high efficiency power converters, wide bandgap semiconductor devices are being turned to. These devices, specifically Silicon Carbide (SiC) devices, offer high temperature and high voltage operation that a traditional Silicon (Si) device cannot. Coupled with fast switching transients, these metal oxide semiconductors field effect transistors (MOSFETs), could provide higher levels of efficiency and power density. This work investigates the benefits of a three-dimensional (3D) printed circuit board (PCB) layout. With this type of layout, a critical parasitic – inductance – can be minimized. As the SiC device can operate at high switching speeds, they incur higher di/dt, and dv/dt slew rates. If trace inductance is not minimal, overshoots and ringing will occur. This can be addressed by stacking PCB traces on top of one another, the induced magnetic field can be reduced. In turn, the system inductance is lowered as well. The reduction of this parameter in the system, reduces the overshoot and ringing. This particular work applies this technique to a 15kW matrix converter. This converter poses a particular design challenge as there are a large number of devices, which can lead to longer, higher inductance PCB traces. The goal of this work is to minimize the parasitic inductance in this converter for high efficiency, high power density operation.

Повний текст джерелаThe complexity of embedded RF systems in consumer wireless applications is increasing, and requires to improve the integration of RF and microwave passive circuits. New solutions that offer more compactness and performance have to be developed, while maintaining a low manufacturing cost. Among Integrated Passive Devices (IPD) technologies, a 3-D technology has been developed at the LAAS CNRS and by 3DiS Technologies for several years. Results demonstrate that the manufactured solenoids exhibit high compactness and high-performance. This PhD thesis aims to develop the integration process of capacitors in order to evolve the technology towards the fabrication of complex passive RF functions.The manuscript is divided into three chapters. The first chapter reviews the technological processes that enable the manufacture of RF systems and highlights the challenges for integrating high-performance passive components. It also presents the advantages of a low-cost 3-D integration solution such as the one proposed. In the second chapter, we present the development of Metal Insulator Metal (MIM) capacitors. The characterization result show that capacitors present performances equivalent to those identified in the literature with high quality factors. We then manufacture two transformers matched to 50 ohms using capacitors. The technological process is described. The manufactured and measured circuits show that transmission losses are close to those obtained at the maximum available gain of the transformers. These results confirm the good performance of the developed capacitors since they introduce minimal losses for the manufactured circuits. No technological problems are encountered during the manufacturing of the two transformers, which validates the complete technological process for the integration of capacitors and solenoid.Based on these results, we present in the last chapter the development of a 4×4 Butler matrix dedicated to 5G beamforming applications. In a large bandwidth ranging from 24 GHz to 29 GHz, insertion losses for the four outputs of the matrix are under 3.5 dB and the phase difference between the outputs are reached with a deviation of less than 16°. The measured results are at the state of the art and overcome those of the existing IPD solutions, in particular for the occupied aera that does not exceed 0.84 mm2. These performances allow us to conclude on the potential of 3-D IPD technology to achieve an excellent compromise between integration density and performance

Повний текст джерелаMedical imaging is going through a continuous development leading to more available information for the reviewing doctors. The information is a powerful tool in the strive to make reliable diagnosis but it can also be a challenge for the doctor to make use of all the information. This thesis investigates if the computer-based review workplace can be made more efficient using other input devices than the traditional mouse and keyboard. To acquire knowledge about the existing user interactions six interviews have been conducted at two Swedish hospitals. In the thesis a 3D mouse has been integrated into Sectra's review workstation to show what value a complementary device can bring.
The interviews show that the doctors are quite satisfied with the existing workplace but there are areas of improvement. This together with the integration of the 3D mouse gives a hint about the complexity of finding a device that adds enough value to take place on the reviewing doctor's desk.

Повний текст джерелаThe down scaling of MOSFET device is becoming harder and the development of future generation of MOSFET technology is facing some strong difficulties. To overcome this issue, the vertical stacking of MOSFET in replacement of the conventional planar structure is currently investigated. This technique, called 3D VLSI integration, attracts a lot of attention, in research and in the industry. Indeed, this sequential stacking of transistor enables to gain in density and performance without reducing transistors dimensions.More specifically, 3D sequential integration or CoolCube™ at CEA-Leti enables to fully benefit of the third dimension by sequentially manufacturing transistors. Implementing such an integration provides the new constraint of manufacturing top transistor with low thermal budget (below 500°C) in order to preserve bottom-transistor performances. As most of the thermal budget is due to the dopant activation, several innovative techniques are currently investigated at CEA-LETI.In this work, solid phase epitaxy regrowth will be used as the mechanism to activate dopants below 600°C. The aim of this thesis is thus to manufacture and to characterize transistors with low-temperature dopant activation, in order to reach the same performance as devices manufactured with standard thermal budget. The work is organized around the dopant activation, and in three chapters, according to each considered integration scheme (Extension Last/ Extension First, Gate Last/ Gate First) and architecture (FDSOI, FINFET). These chapters, assisted by relevant simulations, electrical and morphological characterizations, will enable to develop a new and stable 500°C recrystallization process for both N and P FETs, and to propose new integration schemes in order to manufacture transistors with low thermal budget and compatible with the 3D sequential integration

Повний текст джерела3D printing is a technology that allows the production of an object by additions of materials layers by layers. This technology has many applications in healthcare: bio-printing of tissues and organs, manufacture of medicines or production of customised medical devices. Over the last fifteen years, the production of anatomical models, surgical guides and implants adapted to the patient's anatomy has grown exponentially in all surgical domains. Nevertheless, the question of its clinical and economic evaluation remains unanswered. The objective of this work is to propose several recommendations for designing an economic evaluation model that would take into account the numerous specificities of this technology. We underlined that existing models are not suitable for evaluating a 3D printed device, in particular by highlighting the importance of organisational impact assessment. Thus, we suggested ten key recommendations to be taken into account when designing a study model for 3D printed medical devices

Повний текст джерелаThis thesis focuses on the role of the environment of the representation, as an important sphere which leads the conception, and the development of architectural project. It aims to analyze the actual professional practice, and also the permanent evolution of the displayed tools used in these domains. The approach proposed by this thesis is based on a systematic-comprehensive matter, this approach try to develop links between the conception (as a first universe based on a collaboration between partners) and a second universe of numeric tools (marked by the interactivity and the vitality). The conception universe is attached to the human factor, to the relations between the practitioner, its professional status and the actors of the project, however the numeric environment presents a second universe based on the idealization and the artificiality of the digital system. The model of the use takes place between these two universes, as an invisible model which forms by the conjunction between a project’s culture and a numerical culture. Three approaches guide the ethnographical analyses realized with the practitioners: the first approach presents the “architect-agency” which develops a professional identity based on the “production” and on the development of adapted specific skills; the second approach concerns “the project” which is presented like a sphere influencing the work and the progress of the conception; the third and last approach is the use of 3D conception as a phenomenon which we aimed to identify in our research

The purpose of this development is to create a 3D volume calculating device for the industrial use to acquire the huge volume of the ultra large-sized scrap or the highly piled-up discarded metal material in the factory. Considering the specific working conditions in this research, the design concept of the system configuration hence focuses on the industrial advantages which include those of a small and portable volume, a detachable mechanical structure, a relatively lower cost and a more apt way of control. By combining the 3D scanning technologies with the following components of the laser distance measurement sensor (LDM301) as well as the accurate real-time positioning pan-tilt unit (PTU-D46-17), coupled with the proper control and the specific volume algorithm from the computer programming language along with the extraction of the color information from the Full HD (1080p) camera, the main objective to calculate the volume of a certain target shall therefore be accomplished in this study.

A high throughput micro-nano-particle separation device with 3D-electrodes was fabricated in this study.The 3D electrodes were fabricated to provide dielectrophoresis (DEP) force by using the combination of silver mirror reaction and microfluidic laminar flow patterning technique.Only one photomask was required during the fabrication process without additional vacuum-based metal deposition processs. Silver mirror reaction solutions were prepared and injected separately into a microchannel. The optimal deposition condition was tested and two parallel 3D electrodes were successfully formed at the liquid –liquid interfaces. Multi-walled carbon nanotubes (MWCNTs)were purified by DEP force according to the electrical characteristics. Raman spectroscopy, ratio, and current-voltage measurements were utilized to compare the purification performance between 3-D electrodes and plannar electrodes. From the experimental results, when we used 3D electrodes to pure MWCNTs, the ratio of conducting MWCNTs could be reduced to 0.71. It was lower than ratio of using planar electrodes. Moreover, current of conducting MWCNTs was increased by 3D electrodes. It shows that 3D electrodes could provide higher purification. In this study, we have developed a simple and rapid method to deposit 3D electrodes. The advantages of 3D electrodes are the reduction of applied voltage and Joule heating due to high thickness. This work has been able to attain higher purification for such a lap-on-a-chip application.
