Abstract:
Nowadays, 2-D DCT is applied widely. But the transform matrix of DCT is expressed with floating-point numbers, so the computational complexity is high and more system resources are occupied. In addition, the 2-D DCT is accomplished by operating 1-D DCT to the rows and columns of 2-D data successively, which cannt embody the total space characteristic of 2-D transform well. To overcome these drawbacks, 2-D integer SDCT (Sub-matrix Discrete Cosine Transform) was proposed in the paper. First, several matrix operation methods were defined. Then, the basic principle of 2-D integer SDCT was deduced in detail. The theoretic analysis show that 2-D integer SDCT is easy to comprehend, convenient to operate, and simplifies the calculation of 2-D DCT.

Abstract:
With the development of information processing technology, 2-D DCT has been used more and more widely. But the 2-D DCT is accomplished by computing twice 1-D DCT successively, and cannot embody the total space characteristic of 2-D transform well. To overcome such drawbacks, the paper has broken the traditional thinking of DCT operation, and proposed 2-D SDCT operation method. First, some new 2-D matrix operation principles are defined. Then, the transform basic matrix used for 2-D SDCT operation was build and the operation principle of 2-D SDCT is described in detail. Finally, the performance of 2-D SDCT was described systematically. The theoretical analysis shows that the proposed method makes 2-D DCT succinct to express, easy to comprehend and convenient to operate.

Abstract:

This thesis describes the design of fast JPEG processing accelerators for a DSP processor.

Certain computation tasks are moved from the DSP processor to hardware accelerators. The accelerators are slave co processing machines and are controlled via a new instruction set. The clock cycle and power consumption is reduced by utilizing the custom built hardware. The hardware can perform the tasks in fewer clock cycles and several tasks can run in parallel. This will reduce the total number of clock cycles needed.

First a decoder and an encoder were implemented in DSP assembler. The cycle consumption of the parts was measured and from this the hardware/software partitioning was done. Behavioral models of the accelerators were then written in C++ and the assembly code was modified to work with the new hardware. Finally, the accelerators were implemented using Verilog.

Extension of the accelerator instructions was given following a custom design flow.

Full text
Abstract:
Cette thèse visait l’étude des micro-environnements géochimiques créés par la présence de l’herbier de Zostera noltei et de son réseau racinaire dans le Bassin d’Arcachon ainsi que ses effets 1) sur l’écologie des foraminifères benthiques, un groupe d’organismes présent en grand nombre dans les sédiments et dont l’influence sur les cycles biogéochimiques reste mal connue et 2) sur les espèces chimiques et les flux benthiques associés. Pour y répondre, une stratégie multidisciplinaire a été mise en place. L’étude écologique des foraminifères benthiques à l’échelle centimétrique, conduite dans des sédiments avec et sans végétation en février et juillet 2011, a montré la présence de trois espèces majeures aux métabolismes spécifiques. L’herbier de Zostera noltei semble influencer la densité et la profondeur de vie des espèces calcaires hétérotrophe (Ammonia tepida) et mixotrophe (Haynesina germanica), présentes près de la surface des sédiments. La troisième espèce (Eggerella scabra), au métabolisme anaérobie encore inconnu, est retrouvée sur au moins 7 cm de sédiment et semble préférer le carbone organique issu de la dégradation de l’herbier. En surface, la contribution des foraminifères à la reminéralisation aérobie a été évaluée à 7 % soit 5 fois plus que lors des études précédentes dans d’autres environnements marins. La présence de l’herbier influence également la géochimie du sédiment où des structures enrichies en fer dissous et appauvries en sulfure sont observables en 2D grâce aux gels DET-DGT développés ici. Le phosphate dissous semble dépendre de la demande des zostères et est observé à forte concentration uniquement sous forme de spots. Une tranche de sédiment, prélevée en vis-à-vis du gel DET-DGT visait la réalisation de cartes de la phase solide et de la densité des foraminifères. Bien que ce travail reste inachevé, des méthodes comme la micro-fluorescence et la micro-tomographie aux rayons X donnent des perspectives prometteuses. De nouvelles voies de recherches ont ainsi été ouvertes grâce à des méthodologies innovantes combinant physiologie, écologie et géochimie
This thesis aimed to study the geochemical microenvironments created by Zostera noltei meadows and its root system in Arcachon Basin and to evaluate the effect of these microenvironments 1) on living benthic foraminifera ecology, a group of organisms present in large densities in sediment which impact on marine biogeochemical cycles remain poorly known and 2) on the chemical species and associated benthic fluxes. To fulfill these objectives, a multidisciplinary strategy was developed. The study of benthic foraminiferal ecology at centimeter scale, conducted in sediments with or without vegetation in February and July 2011, has shown the presence of three major species with specific metabolisms. Zostera noltei meadows seem to influence the densities and the living depth of heterotrophic (Ammonia tepida) and mixotrophic (Haynesina germanica) calcareous species, present in the sediment surface. The third species (Eggerella Scabra), which anaerobic metabolism is still to discover, is found throughout the sedimentary column and seems to prefer the organic matter coming from the degradation of the seagrass. In surface sediment, the contribution of these three species to aerobic remineralization was estimated at 7%, i.e. 5 times more than the maximum rates previously recorded in marine environments. The presence of the seagrass also influences geochemistry where enriched iron and depleted sulfide structures are observable in 2D thanks to DET-DGT gels developed here. Dissolved phosphorus depended on seagrass uptake and was highly concentrated only as scattered spots. A slice of sediment, taken face to face with the DET-DGT gel, was also conducted during this study aiming to map the solid phase and foraminiferal density. Despite this work is still in progress, methods such as X-ray microfluorescence and microtomography showed promising perspectives. New research pathways have been opened through technological developments and innovative approaches combining physiology, ecology, and geochemistry

Abstract:
Dans le cadre de la recherche de vecteurs d'énergie “propres”, le borazane et ses dérivés amine-boranes sont devenus des candidats intéressants en tant que matériaux de stockage de l'hydrogène en raison de leur pourcentage massique relativement élevé en hydrogène (19,6% pour borazane) et de la réversibilité potentielle de la réaction de déshydrogénation. Pour des applications réelles, le contrôle des réactions se produisant à la température ambiante est fondamental. Dans ce contexte, la compréhension du processus de la déshydrogénation/déshydrocouplage catalytique de l'amine-borane apparaît comme un élément important. Dans cette thèse, les catalyseurs de types métallocènes du Groupe IV (Cp2M, M = Ti, Zr et Hf) sont étudiés en détail. Le déshydrocouplage de HMe2N·BH3 catalysé par le titanocène a été étudié à la fois expérimentalement et théoriquement mais aucun accord n'avait été atteint auparavant. Dans ce travail, les caractérisations systématiques des interactions 3-centre 2-électron M···H-B impliquées dans les intermédiaires réactionnels ont été réalisées avec des approches topologiques QTAIM et ELF. Par la suite, des mécanismes réactionnels détaillés ont été étudiés. Les résultats théoriques ont démontré que la méthode DFT corrigée avec la dispersion (DFT-D) étaient nécessaire et suffisantes pour une description énergétique correcte des chemins réactionnels. Mon travail a également permis l'identification d'un complexe de van der Waals jouant un rôle clé dans le mécanisme réactionnel en accord avec les observations expérimentales
With the increasing demand of clean energy carriers, ammonia borane and its related amine-borane compounds have emerged as attractive candidates for hydrogen storage materials due to their relatively high weight percentage of available hydrogen (19.6% for ammonia borane) as well as the potential reversibility for the hydrogen release reactions. Actual applications would benefit from controlled reactions occurring close to room-temperature. In this context, catalytic dehydrogenation/dehydrocoupling of amine-borane appears as a promising solution. In this thesis the Group IV metallocene (Cp2M, M = Ti, Zr and Hf) are mainly discussed. The dehydrocoupling of HMe2N·BH3 catalyzed by titanocene was investigated both experimentally and theoretically but no agreement were reached. In this work, systematic characterization of M···H-B 3-center 2-electron interactions involved in reaction intermediates were carried out with QTAIM and ELF topological approaches. Afterwards, detailed mechanisms were further studied. Computational results have demonstrated that the dispersion corrected DFT (DFT-D) method was indispensable for a correct enegetic prediction for reaction pathways. The identification of a van der Waals complexe also plays a central role for a reaction mechanism with good agreement with experimental observations

Abstract:
Dans cette thèse, nous avons étudié les propriétés de deux matériaux 2D constitués de germanium : le germanène, l'équivalent du graphène, et un empilement multicouche de germanane à terminaison méthyle. En raison d’une structure atomique gauchie et d’un couplage spin orbite important, ces matériaux se démarquent du graphène et du graphite. Bien que très étudiés théoriquement, leurs propriétés physiques restent encore peu caractérisées. Dans le cas du germanène, l’étude de ce matériau a été réalisée en déposant du germanium sur une surface d’aluminium (111) sous ultravide. Pour des températures de croissance relativement basses, autour de 100°C, le germanène est épitaxié avec deux structures : la phase (3x3) et la phase (√7x√7). La microscopie à effet tunnel a été utilisée pour approfondir notre connaissance de ces phases. Dans un premier temps nous nous sommes intéressés aux propriétés électroniques. Des mesures spectroscopiques par microscopie à effet tunnel ont été réalisées à des températures de 77K et 5K. Elles n’ont malheureusement pas permis de conclure quant à la véritable nature du germanène en raison du fort couplage électronique de ce matériau avec la surface d’aluminium. Toutefois, au travers d’une diversité inattendue de spectres, cette analyse a révélé la faible adhésion du germanène à la surface Al(111), ce qui conduit à une contamination fréquente de l’apex de la pointe du microscope par les atomes de la surface. Parallèlement aux mesures spectroscopiques, la croissance de feuillets aux dimensions réduites a permis d’étudier la structure des bords des feuillets. Les observations par microscopie à effet tunnel montrent que ces feuillets croissent dans le plan des terrasses atomiques d’aluminium. Leurs bords présentent généralement un contraste plus clair que le reste du feuillet. Pour mieux comprendre ce changement de contraste, des calculs ab-initio basés sur la théorie de la fonctionnelle de la densité (DFT), ont été développés. Ils ont montré le rôle clé des atomes d’aluminium dans la formation des bords possédant quelque soit la structure zigzag ou « armchair ». A l’inverse du germanène mono-feuillet qui requiert une épitaxie, des cristaux de germanane peuvent être synthétisé par voie chimique, ce qui assure un découplage électronique du matériau avec son environnement. Nous avons réalisé une analyse multiphysique de tels cristaux passivés par des groupements méthyles, qui révèlent deux types de cristaux. Les plus gros, autour de 10 m de dimension latérale, sont polycristallins, recèlent des molécules intercalées entre les feuillets ou possèdent des surfaces oxydés et se chargent sous irradiation électronique en raison de la présence d’isopropanol à l’interface avec le substrat hôte. Les plus petits, identifiés comme les plus purs, sont les plus enclins à être caractérises par des mesures de transport à quatre pointes en ultravide. Ces mesures ont montré un transport de trous, qui se produit en volume. Ce résultat inattendu pour un matériau lamellaire suggère la présence de défauts et d’imperfection dans le plan des feuillets qui appellent à un meilleur contrôle de la synthèse des cristaux pour rendre possible l’étude des propriétés physiques fondamentales de ces cristaux
In this thesis, we have studied the properties of two 2D materials made of germanium: germanene, the equivalent of graphene, and a multilayer stack of germanene terminated with methyl groups. Due to a buckled atomic structure and a strong spin orbit coupling, these materials stand out from graphene and graphite. Although much studied in theory, their physical properties remain little characterized. In the case of germanene, the study of this material was carried out by depositing germanium on an aluminum (111) surface in ultra-high vacuum. For relatively low temperatures, around 100° C, the growth of germanene is epitaxial with two structures: the (3x3) reconstruction and the (√7x√7) reconstruction. Scanning tunneling microscopy has been used to deepen our knowledge of these phases. First of all, we were interested in the electronic properties. Spectroscopic measurements were carried out at temperatures of 77K and 5K. Unfortunately, they did not reveal the true nature of germanene due to the strong electronic coupling of this material with the aluminum surface.Throughout an unexpected diversity of spectra, this analysis showed the weak adhesion of germanene to the Al(111) surface, which leads to frequent contamination of the apex of the tip of the microscope by atoms of the area. In addition to spectroscopic measurements, the growth of small-sized sheets enabled the study of the edge structure. Observations by tunneling microscopy showed that these sheets grow in the plane of the aluminum atomic terraces. Their edges generally present a clearer contrast than the rest of the sheet. To better understand this change of contrast, ab-initio calculations based on density functional theory (DFT) have been performed. They showed the key role of aluminum atoms in the formation of edges, with both zigzag or armchair structures. Unlike single-sheet germanene which requires an epitaxial growth, germanane crystals can be chemically synthesized, which ensures the electronic decoupling of the material from its environment. We carried out a multi-physics analysis of such crystals passivated by methyl groups, which revealed two types of crystals. The largest, around 10 micrometres in lateral dimension, are polycrystalline, contain water molecules intercalated between the layers or have oxidized surfaces and become charged under electron irradiation due to the presence of isopropanol at the interface with the host substrate. The smallest, identified as the purest, are the most prone to being characterized by ultra-high vacuum four-probe transport measurements. These measurements showed a transport of holes, which occurs in the volume of the microstructure. This unexpected bulk transport for a lamellar material suggests the presence of defects and imperfection in the plane of the layers, which calls for a better control of the synthesis of these crystals

Abstract:
Digital breast tomosynthesis (DBT) is a relatively new X-ray technique that allows quasi–three-dimensional imaging of the breast to overcome limitations of conventional 2-D digital mammography (DM). Several early screening studies have shown that DBT reduces the number of false-positive recalls while simultaneously improving the cancer detection rate. Cost-effectiveness studies have shown that incorporating DBT in screening has the potential to save health care dollars due to lower recall rates as well as reduced treatment costs resulting from the earlier detection of breast cancer. In the diagnostic setting, DBT imaging may allow a more efficient work-up of breast lesions due to improved lesion conspicuity and the ability to better localize lesions within the breast.

Abstract:
Late in 1970, President Nixon proposed and Congress approved creation of the Environmental Protection Agency (EPA), in the process transferring the Pesticide Regulation Division from USDA to EPA. For pesticide regulation, this was no minor matter. The transfer was from USDA, an agency that primarily protected pesticide manufacturers and promoted their products, to EPA, an agency that was directly charged with protecting the environment. That was to make a large difference in how the DDT issue would be resolved. The first administrator of EPA was William D. Ruckelshaus, an attorney with a sterling record of public service in government. The other major item was the decision on DDT from the DC Court of Appeals. On January 7, 1971, the court ordered Ruckelshaus to immediately cancel all registrations of DDT and to determine whether DDT was “an imminent hazard to the public” and therefore should be suspended. The court was clearly annoyed by USDA’s failure to give adequate reasons for not suspending, so “it will be necessary to remand the case once more, for a fresh determination” of the matter of suspension. The court had taken away the discretion usually afforded a federal agency and ordered it to take action. This was an unprecedented decision. EPA had only been created on December 2, 1970; Ruckelshaus barely had time to find his telephone before this court order landed on his desk as his first order of business. Perhaps the most important part of this decision was that EDF survived USDA’s motions to throw our case out of court. The standing for citizens to sue the government, previously unavailable, had now been established by this precedent-setting decision. This was the firm beginning of what we now call “environmental law.” But you should not take the legal conclusion of a lowly scientist (me). Instead, here are the words of Joseph L. Sax, a professor of law at the University of Michigan Law School, from his September 30, 1973, letter in support of EDF’s application for the Tyler Ecology Award (we did not get it).

Abstract:
Entrepreneurship correlates to the entrepreneur who is creative, has risk taking capability, promotes capital formation, and seeks out investment opportunities in the market. In the National Institute for Transforming India Aayog's 5th Governing Council, the Government of India (GoI) aims to take the Indian economy to USD 5 trillion by 2024. Thus, India needs to significantly increase employment opportunities for which GoI is promoting skill development through biotechnology entrepreneurship and investing appreciably with a special focus on R&D to develop India into a world class bio-manufacturing hub. The DBT in collaboration with BIRAC has implemented flagship schemes such as ‘Make in India' and ‘Start up India'. The major objectives of this chapter are to lay out (1) the role of GoI to empower startups for growth through innovation and design, (2) a detailed overview of the various schemes offered by GoI for promoting skill development and innovation through bio-entrepreneurship, (3) major challenges faced by the government for implementation of schemes.

Abstract:
The reader, even if familiar with vectors, will find it useful to work through this chapter because it introduces notation that will be used throughout this book. We will take vectors to be entities that possess magnitude, orientation, and sense in three-dimensional space. Graphically, we will represent them as arrows with the sense from tail to head, magnitude proportional to the length, and orientation indicated by the angles they form with a given set of reference directions. Two different kinds of symbol will be used to designate vectors algebraically, boldface letters (and the boldface number zero for a vector of zero magnitude), and subscripted letters to be introduced later. The first problems deal with simple vector geometry and its algebraic representation. Multiplying a vector by a scalar affects only its magnitude (length) without changing its direction. Problem 1. State the necessary and sufficient conditions for the three vectors A, B, and C to form a triangle. (Problems 1–9, 12–14, 19–23, and 25 from Sokolnikoff & Redheffer, 1958.) Problem 2. Given the sum S = A + B and the difference D = A – B, find A and B in terms of S and D (a) graphically and (b) algebraically. Problem 3. (a) State the unit vector a with the same direction as a nonzero vector A. (b) Let two nonzero vectors A and B issue from the same point, forming an angle between them; using the result of (a), find a vector that bisects this angle. Problem 4. Using vector methods, show that a line from one of the vertices of a parallelogram to the midpoint of one of the nonadjacent sides trisects one of the diagonals. Two vectors are said to form with each other two distinct products: a scalar, the dot product, and a vector, the cross product.

Abstract:
The work raises questions of predicting the complications of pregnancy and childbirth and adverse conditions in the fetus in the presence of UCTD in the expectant mother, who also need to be studied, especially from the standpoint of mathematical modeling of the disease. It is also necessary to develop a common tactic for providing medical and social assistance and treatment and diagnostic services to pregnant women suffering from UCTD, which will make the outcome of childbirth more favorable and improve the subsequent prognosis for mother and newborn. In the literature there is practically no assessment of the course of pregnancy and the outcome of childbirth, depending on the severity of UCTD. Little is known about the role of a connective tissue metabolism marker - hydroxyproline, trace elements (magnesium) and vitamins (D3) in pregnant women suffering from UCTD, and the medical tactics regarding such patients are not clearly defined. Despite numerous successes in the study of the causes of complications during pregnancy and childbirth in women suffering from UCTD, a unified approach to their management during the prenatal stage has not yet been developed. Therefore, the search for possible predictors for the timely prediction of adverse pregnancy and childbirth outcome in such patients is becoming increasingly important. This will make it possible to develop an optimal organizational and methodological base and subsequently improve the prognosis for women and their offspring. Thus, in contrast to the existing standard approach, we have proposed a comprehensive management of patients suffering from UCTD, including the timely identification of patients from the risk group, clarification of their condition using such markers as magnesium and hydroxyproline, additional intake of magnesium and vitamin D preparations. Optimal plan managing the period of gestation, childbirth, and a pathogenetically reasoned set of treatment and preventive measures for women with UCTD, will not only improve the outcomes of pregnancy and childbirth, but also contribute to the health of the future generation. 1. UCTD affects the course of pregnancy, childbirth and the condition of the newborn. The degree of exposure is largely determined by the severity of the underlying disease. In severe UCTD, the prevalence of spontaneous miscarriage and preterm labor was significantly higher, and endometritis and severe anemia were more common in the postpartum period. Severe asphyxia on the Apgar scale at the 1st and 5th minutes, congenital heart defects, morphofunctional immaturity, conjugation jaundice and convulsive syndrome were more common in the fetus. 2. A low content of magnesium and hydroxyproline is associated with the occurrence of complications during childbirth and a decrease in the anthropometric characteristics of the newborn. Taking magnesium preparations reliably affects the concentration of this trace element and hydroxyproline in the blood of pregnant women suffering from UCTD. 3. Therapy with magnesium preparations is an effective tool in patients suffering from UCTD, as it helps to improve well-being during pregnancy, improves the course of the postpartum period and reduces the prevalence of chronic fetal hypoxia. 4. Vitamin D and magnesium supplements have a beneficial effect on pregnancy and the fetus, reducing the prevalence of pre-eclampsia and chronic intrauterine hypoxia of the fetus, reducing the incidence of morphofunctional immaturity and conjugation jaundice of the newborn. 5. The created computer program “STEP DST” can be applied in the clinical practice of obstetrician-gynecologists and health care organizers. The obtained individual forecast of the probability of development of complications of reproduction allows us to outline the optimal plan for managing the period of gestation, childbirth and the postpartum period, to prescribe a pathogenetically based set of therapeutic and preventive measures for women suffering from UCTD.
