Modelling and Characterisation of Terahertz Planar Schottky Diodes

This thesis deals with the modelling and characterisation of THz planar Schottky diodes, focusing on analyses of geometry-dependent electrical parasitics and the thermal management of the diode chip. Moving towards higher operating frequencies, the diode performance degrades due to high frequency losses, parasitic couplings and self-heating effects. For geometry-dependent electrical parasitics analyses, the diode equivalent circuit parameters can be extracted from the measured or 3-D EM calculated S-parameters. For planar Schottky diodes, the available parameter extraction methods are typically based on an optimisation approach. In this work, a parameter extraction method based on an analytical approach is proposed. The proposed method allows for a fast and more reliable diode model extraction. In this work, the high frequency diode parasitic esistance model is extended to include the eddy current and a mixture of skin and proximity effects. Due to the eddy current and proximity effects, the upper boundary of the buffer layer thickness is approximately one skin depth at the operating frequency, whereas the lower boundary is limited by the spreading resistance at DC. Reactive energies stored in the parasitic capacitances and inductances cause an inherent limitation in the power coupling bandwidth to the intrinsic diode junction. The influence of diode geometry on fundamental power coupling bandwidth limitation is analysed using the Bode-Fano criterion. The result shows a trade-off between the parasitic capacitance and finger inductance,determined by the pad-to-pad distance, in optimising the diode geometry for a wide band diode matching. A systematic thermal analysis of a 200 GHz multiplier chip developed by JPL is performed. The result shows that the chip thermal resistance is in the order of 10^3 K/W, whereas the overall thermal settling time is more than tens of milliseconds. The simulation result is verified through thermal imaging using infrared microscopy. Taking the thermal analysis a step further, a self-consistent electrothermal model for the multiplier chip is proposed. Compared to the circuit analysis without the thermal model, analysis with the electrothermal model shows a better agreement with the measured result, e.g., an error reduction from ~13% to ~4% between the simulated and measured maximum output power, by including the thermal effect.

The adapted city : institutional dynamics and structural change

Emphasizing the importance of the space programme to the scientific, social and cultural history of the last half of the 20th century, this brief history celebrates the almost unimaginable technological leap that the space programme represents, a feat of teamwork, innovation, dedication and mastery unprecedented in the history of mankind. Walsh's narrative begins just before the Mercury programme, covers the original seven astronauts, the Gemini and Apollo programmes, through Skylab and up to the space shuttle. The glories and emotion of space exploration are presented against the backdrop of the Cold War, the presidential administrations of Eisenhower, JFK, LBJ, Nixon, Ford and Carter, and other singificant events in US history. The positive accomplishments of the astronauts are put in context of an increasingly negative domestic situation in the '60s and '70s, the Bay of Pigs, civil rights, assassinations, growing involvement in and dissension about Vietnam, the Watergate scandal, and Nixon's resignation.
Empirical Comparisons of Virtual Environment Displays

There are many different visual display devices used in virtual environment (VE) systems. These displays vary along many dimensions, such as resolution, field of view, level of immersion, quality of stereo, and so on. In general, no guidelines exist to choose an appropriate display for a particular VE application. Our goal in this work is to develop such guidelines on the basis of empirical results. We present two initial experiments comparing head-mounted displays with a workbench display and a foursided spatially immersive display. The results indicate that the physical characteristics of the displays, users' prior experiences, and even the order in which the displays are presented can have significant effects on performance.
An adaptive model predictive control strategy for a class of discrete‐time linear systems with parametric uncertainty

In this study, an adaptive model predictive control (MPC) strategy is proposed for a class of discrete‐time linear systems with parametric uncertainty. In the presented adaptive MPC, an updating law is firstly designed to update the estimated parameters online. By utilizing the estimated parameters, a standard MPC optimization problem for unconstrained systems is established. Then, to deal with constrained systems, the min–max MPC technique is developed under the set‐based approach for the estimated parameters. Furthermore, it is shown theoretically that the recursive feasibility and closed‐loop stability can be rigorously proved, respectively. Finally, numerical simulations and comparative analysis are presented to illustrate the superiority of the proposed algorithms in control performance.
Flow-level network models: have we reached the limits?

Project-Team MESCALResearch Report n° 7821  November 2011  24 pagesAbstract: Researchers in the area of distributed computing conduct many of their experiments in simula-tion. While packet-level simulation is often used to study network protocols, it can be too costly to simulatenetwork communications for large-scale systems and applications. The alternative is to simulate the net-work based on less costly ow-level models. Surprisingly, in the literature, validation of these ow-levelmodels is at best a mere verication for a few simple cases. Consequently, although distributed computingsimulators are widely used, their ability to produce scientically meaningful results is in doubt. In thiswork we focus on the validation of state-of-the-art ow-level network models of TCP communication, viacomparison to packet-level simulation. While it is straightforward to show cases in which previously pro-posed models lead to good results, instead we systematically seek cases that lead to invalid results. Carefulanalysis of these cases reveal fundamental aws and also suggest improvements. One contribution of thiswork is that these improvements lead to a new model that, while far from being perfect, improves uponall previously proposed models. A more important contribution, perhaps, is provided by the pitfalls andunexpected behaviors encountered in this work, leading to a number of enlightening lessons. In particu-lar, this work shows that model validation cannot be achieved solely by exhibiting (possibly many) goodcases.  Condence in the quality of a model can only be strengthened throughan invalidationapproachthatattempts to prove the model wrong.Key-words: Simulation, uid network models, validity, methodology

Biofiltration of dichloromethane vapours: isolation of microorganisms

This paper presents preliminary results about realization of a DCM degrading vapour-phase biofilter. Specific microorganisms were isolated from chloorganics contaminated soils and selected after screening growth tests in the presence of DCM at different concentrations. A strain of Penicillium and a microbial consortium were isolated and separately inoculated into two identical lab-scale bioreactors (0.5L volume) packed with expanded clay in granular form. Results revealed better performance for the consortium than Penicillium, but for both the biomasses elimination capacity was very low (< 50 gm-3h-1) and removal efficiency decreased below 20% after about 2 months operation. A new isolation process was then carried out from a municipal waste sludge and a new microbial consortium was isolated and batch growth kinetics in the presence of dichloromethane at different pHs was investigated.
INTERRELATIONSHIPS AMONG AIRPORTS AND THE HINTERLAND PLAYERS. A VALUE NETWORK ANALYSIS APPROACH

The measure of an airport performance and its efficiency is generally made using operational and financial data, thus providing a position rank in respect to a set of airports. But this methodology, by itself, cannot provide the true relationships between a certain position in the rank of an airport and the generated value associated with that position, either within the entire business system of the airport or within the inter-relationships that it establishes with the surrounding community. To understand the role that airport infrastructure plays within the regional development, not only a variety of relationships must be recognized, but also how they create or may create value. For better understanding of how processes and people create value in an airport network ecosystem, it is possible to use Value Network Analysis (VNA). VNA is a methodology that provides a capability to understand, visualize and optimize internal and external value networks of complex economic ecosystems, thus capturing dynamics of the entire system. This paper presents a map of the interrelationships between the airportâ€™s players and the hinterlandâ€™s players in three different scenarios, the air traveler, the supply chain, and the infrastructure development, considering the related impacts in the form of the tertiary effects and the perpetual effects. The first scenario results from the existence of the air transport services for the use of individuals. The second is related with the airport suppliers and the services supplies to the air passenger and cargo when companies need a high speed and quality transport services. The third scenario considers perpetual effects associated with the regional economy considering that an infrastructure investment will raise the level of activity and stimulates productivity. These scenarios are comprised in a adapted model with four interconnected interface domains that we assume reinforce the sustainability of airport business activities within a territory in the long-term: Economic Development, Land Use, Infrastructures and Governance. This model is essentially an organizing tool that identifies key policy areas to improve integrated decision-making processes and is a conceptual framework for future research. The application of VNA methodology allows the recognition and assessment of impacts and relationships between multiple systems, thus avoiding an ad-hoc analysis and compartmentalized of issues. In the context of the present study not only a variety of relationships are recognized, but also how they create or may create value, allowing a better understanding of the role that airport infrastructure plays within the regional development.

NIF Target Assembly Metrology Methodology and Results

Abstract Inertial confinement fusion (ICF) experiments at the National Ignition Facility (NIF) require cryogenic targets at the 1-cm scale to be fabricated, assembled, and metrologized to micron-level tolerances. During assembly of these ICF targets, there are physical dimension metrology steps to be made of the components, subassemblies, and completed targets. Metrology is primarily completed using optical coordinate measurement machines that provide repeatable measurements with micron precision, while also allowing in-process data collection for absolute accuracy in assembly. To date, 51 targets have been assembled and metrologized, and 34 targets have been successfully fielded on NIF relying on these metrology data. In the near future, ignition experiments on NIF will require tighter tolerances and more demanding target assembly and metrology capability. Metrology methods, calculations, and uncertainty estimates will be discussed. Target diagnostic port alignment, target position, and capsule location results will be reviewed for the 2009 Energetics Campaign. The information is presented via control charts showing the effect of process improvements that were made during target production. Certain parameters, including capsule position, met the 2009 campaign specifications but will have much tighter requirements in the future. To meet these new requirements assembly process changes and metrology capability upgrades will be necessary.
Les Déterminants des Performances Scolaires des Elèves Marocains.

The objective of this paper is to assess the determinants of student achievements in Morocco. This study is of great interest given the deterioration of educational quality in this country and the absence of major studies that assess its educational system. The work we are undertaking seeks to shed light on the factors that explain student achievements; these include school environment and peer group characteristics in addition to the socio-economic background of the student. Our study utilizes the National Survey for the Assessment of Achievements 2008 (Programme National d’Evaluation des Acquis), and estimates an education production function which has for an output the score by discipline and level. It also provides a new approach that takes into account methodological problems, corrects the various biases and generates consistent results. The results of the various estimates indicate that student background plays a significant role in their academic performances. For instance, grade repetition has a negative influence on student achievements and the same applies for delayed entry, and the lack of material and cultural inputs, etc. Another important result concerns the influence of peer characteristics on student performances.
Cardiac contractility modulation regulates the structural and electrical remolding in chronic heart failure rabbit model

Background Chronic heart failure (CHF) is accompanied by complex changes in cardiac electrophysiology and functional properties of cardiomyocytes which cause the structural and electrical remodeling process. Cardiac contractility modulation (CCM) is a novel therapeutic method and has proven to be effective in improving cardiac function. This study evaluated the effects of CCM on structural and electrical remolding in a rabbit model of CHF. Methods Thirty rabbits were randomly divided into sham group, heart failure group and CCM group. CHF model was induced 12 weeks after trans aortic constriction by pressure unloading. Then cardiac contractility modulation was delivered to the myocardium lasting six hours per day for 4 weeks. Structural changes were assessed by hydroxyproline assay and picrosirius red staining. The QTc intervals, ventricular effective refractory period and the inducibility of ventricular tachycardia were measured by electrophysiological examination. Protein levels of CTGF, Gal-3, Kv4.3, KCNQ1, KCNH2 and CX43 were measured by western blot analysis. Results Our study revealed that CHF rabbits developed significant prolonged QTc, ventricular effective refractory period and increased inducibility of ventricular tachycardia. Prominent myocardial fibrosis and increased levels of hydroxyproline content were observed in the heart failure group. Changes mentioned above can be suppressed with CCM therapy in CHF rabbits. The protein levels of CTGF, Gal-3, Kv4.3, KCNQ1, KCNH2 and CX43 significantly increased in the heart failure group, but these changes were prevented in the CCM group. Conclusions The present study demonstrated that CCM treatment prevented myocardial structural and electrical remolding in a rabbit model of CHF. The beneficial effect of CCM may be related to prevention of downregulation of the CTGF, Gal-3, Kv4.3, KCNQ1, KCNH2 and CX43. These findings provide experimental evidence for the clinical use of CCM in the treatment of HF.
Design for Reliability: Information and Computer-Based Systems

System reliability, availability and robustness are often not well understood by system architects, engineers and developers. They often dont understand what drives customers availability expectations, how to frame verifiable availability/robustness requirements, how to manage and budget availability/robustness, how to methodically architect and design systems that meet robustness requirements, and so on. The book takes a very pragmatic approach of framing reliability and robustness as a functional aspect of a system so that architects, designers, developers and testers can address it as a concrete, functional attribute of a system, rather than an abstract, non-functional notion.
The drinking behaviour of dairy cows in late lactation

The drinking behaviour of grazing cows was investigated in two studies with the purpose of determining the suitability of using water intake as a motivator for voluntary movement of cows within a pasture-based automatic milking system (AMS). In the first study 100 mixed-age Jersey cows in late lactation were observed for 48 h. Cows drank on average 2.4 times/24 h (range: 1-6) and usually alone or with one or two other animals. Although every cow drank at least twice during the 48 h, 31% of cows recorded an interval between drinks > 24 h. Less than 1% of drinking occurred between 2000 h and 0700 h. The second study compared the drinking behaviour of Overseas (OS) and New Zealand (NZ) Holstein Friesian cows that were either grazing pasture (GRASS) or fed a Total Mixed Ration (TMR). TMR cows drank more often (5.2 times/24 h) than GRASS cows (3.5 times/24 h, P < 0.001). Feed type altered the distribution of drinking with 76.8 % of TMR cows drinking between 2000 h and 0700 h compared with only 24.5% for GRASS. Water intake was also higher for TMR (73.0 L/cow/day) compared with GRASS (53.7 L/cow/day) animals. The studies showed that the individual nature of drinking behaviour would be aligned with the AMS objectives of distributed rather than batch milking. However, the small number of cows drinking during darkness when grazing indicates that water intake would need to be used in combination with other motivators to ensure a continuous flow of cows to the dairy.
