Full textAbstract:
Cells of Methanothrix concilii do not possess rigid, shape-forming cell walls; they obtain their cellular form from the portions of the sheath and spacer plugs which enclose them. Electron microscopy has shown that cell division proceeds by the ingrowth of spacer plugs, like the closing of a camera iris, from select regions of the sheath; this process forces the cells to split in two. Therefore, each spacer plug which traverses the filament of cells is a completed division annulus. Spacer plugs are two-layered structures; one layer is an assembly of fine concentric rings and is the first to be laid down during the division ingrowth. The second layer consists of larger, raised, concentric ribbons which progressively follow the advance of the first layer during division. Although cells within the filament are typically 2.5 μm long, new daughter cells are ca. 1.0 μm and can grow to ca. 4.0 μm before division begins. Frequently, a developing spacer plug partitions a cell so that one daughter is a small, nonreplicating unit of protoplasm sandwiched between two completed plugs; eventually, this protoplasmic unit dies leaving a void in the chain of cells. The filament is susceptible to breakage at this juncture. In this instance, each of the two "void" plugs becomes a new terminal plug for the new ends of the split filament. This type of replication requires both cell division and filament splitting, and the series of structural events which are involved present a new form of prokaryotic division.

Deep learning; it is often used in dividing processes on images in the biomedical field. In recent years, it has been observed that there is an increase in the division procedures performed on prostate images using deep learning compared to other methods of image division. Looking at the literature; It is seen that the process of dividing prostate images, which are carried out with deep learning, is an important step for the diagnosis and treatment of prostate cancer. For this reason, in this study; to be a source for future splitting operations; deep learning splitting procedures on prostate images obtained from magnetic resonance (MRI) imaging devices were examined. Key words: deep learning, image division, prostate cancer

Full textAbstract:
Periodizations are political acts. They produce temporalities that do not necessarily coincide with chronology. TWAIL (Third World Approaches to International Law) scholars have generally endorsed the division of TWAIL into two generations. Whereas TWAIL I was composed by scholars that thought and wrote about international law during the decolonization process, TWAIL II began at the end of the 1990s. Although there are common features between the generations, a number of differences are also identified and emphasized by TWAIL II scholars. In this article, I advance the argument that such periodization is problematic for four reasons: anachronism, progressivism, a difficult self-identification of past third world legal scholars with TWAIL and the image made of TWAIL by non-TWAILers. Instead of periodizing TWAIL in two successive generations, I argue that identifying it as part of a larger tradition of third world international legal scholarship is more productive for the inner coherence of the intellectual movement and, consequently, for its success in the international legal academia.

Full textAbstract:
Proper cell division site placement in the extensively studied rod Escherichia coli (Ec) is determined by the Min proteins. MinDEc recruits MinCEc to the membrane to inhibit cell division. MinEEc restricts MinCEc-MinDEc activity to cell pole regions by inducing MinDEc ATPase activity and causing it to dynamically oscillate from end-to-end in E. coli . The Dillon laboratory has identified min gene homologues in the coccus Neisseria gonorrhoeae (Ng) which, unlike E. coli, divides along two dimensions. This study investigates the role and identifies functional domains of gonococcal MinD (MinDNg).
MinD is implicated in Neisseria gonorrhoeae cell division. Inactivation of minDNg dramatically disrupted N. gonorrhoeae division patterns and reduced cell viability. Overexpression of MinDNg and MinCNg together in the gonococcus inhibited cell division, producing grossly enlarged cells. MinDNg could complement an E. coli minD mutant and induced cell division arrest in this organism, provided endogenous E. coli MinC was present. GFP-MinDNg fusions also displayed MinENg-dependent oscillations within a coiled array in rod-shaped and round mutant E. coli.
The self-interaction of MinDNg, as well as MinDEc, was detected using yeast two-hybrid assays, the first report of such interactions. Furthermore, size-exclusion chromatography and analytical ultracentrifugation showed purified MinDNg to be dimeric. MinDNg also interacted with both MinENg and MinC by yeast two-hybrid experiments.
Structural and sequence alignments implicated a polar region, containing amino acids 92--94, in MinD dimerization. However, mutations to these residues did not eliminate interaction of MinDNg with itself, MinC, or MinE. Interestingly, this region may have a role in permitting bacterial MinD to respond to MinE stimulation, since mutant GFP-MinD fusions failed to oscillate from pole-to-pole in E. coli, despite being distributed uniformly within a coiled array. This was supported by in vitro assays, where MinENg was unable to stimulate the ATPase activity of mutated MinDNg.
The conserved extreme N-terminus of MinDNg was also studied and shown to have a role in affecting MinDNg ATPase activity and localization dynamics. Successive truncation or mutation of this region affected MinDNg interaction with other Min proteins. Significantly, these alterations resulted in faster GFP-MinDNg oscillation cycles and increased tendencies to remain in the cytoplasm. Mutant MinDNg displaying this behaviour possessed hyper-ATPase activities independent of MinENg.
This is the first study to characterize MinD from a naturally occurring coccus and demonstrates the protein acts as a cell division site determinant in N. gonorrhoeae and in E. coli. Results from this study were used to generate a model for N. gonorrhoeae cell division.

Full textAbstract:
La nouvelle génération de réseaux mobiles (5G) devrait faire face, durant les cinq prochaines années, à une importante croissance du volume de données, échangé entre plusieurs milliards d'objets et d'applications connectés. En outre, l'émergence de nouvelles technologies, telles que Internet of Things (IoT), conduite autonome et réalité augmentée, impose de plus fortes contraintes de performance et de qualité de service (QoS). Répondre aux besoins cités, tout en réduisant les dépenses d'investissement et d'exploitation (CAPEX/OPEX), sont les objectifs poursuivis par les opérateurs télécom, qui ont défini une nouvelle architecture d'accès radio, appelée Cloud Radio Access Network (C-RAN). Le principe du C-RAN est de centraliser, au sein d'un pool, les parties de traitement, BaseBand Unit (BBU), d'un RAN traditionnel. Les BBU sont alors dissociées de la station de base et de la partie radio, Remote Radio Unit (RRU). Ces deux parties restent néanmoins connectées à travers un réseau intermédiaire appelé Fronthaul (FH). Dans cette thèse, nous allons concevoir une nouvelle architecture C-RAN partiellement centralisée qui intègrera une plateforme de virtualisation basée sur un environnement Xen, nommée " Metamorphic Network " (MNet). A travers cette architecture, nous viserons à : i) mettre en place un pool, dans lequel des ressources physiques (processeurs, mémoire, ports réseaux, etc.) seront partagées entre des BBU virtualisées et d'autres applications, ii) établir un réseau FH ouvert aux fournisseurs de services et aux tierces parties, facilitant ainsi le déploiement des services au plus près des utilisateurs, pour une meilleure qualité d'expérience, iii) exploiter, à travers le FH, les infrastructures Ethernet existantes pour réduire les CAPEX/OPEX et enfin, iv) atteindre les performances réseau préconisées pour la 5G. Dans la première contribution, nous allons définir une nouvelle architecture Xen pour la plateforme MNet, intégrant le framework de packet processing, OpenDataPlane (ODP), au sein d’un domaine Xen privilégié, nommé « Driver Domain ». Notre objectif, à travers cette architecture, est d’accélérer le traitement des paquets de données transitant par MNet, en évitant la surutilisation, par ODP, des cœurs du processeur physique (CPU) de la plateforme. Pour cela, des cœurs CPU virtuels (vCPU) seront alloués dans le Driver Domain pour être exploités durant le traitement des paquets par ODP. Cette nouvelle plateforme MNet servira de base pour notre architecture C-RAN. Dans la seconde contribution, nous allons implémenter, au sein du FH, deux solutions réseau. La première solution, consistera à déployer le réseau de couche 2, Transparent Interconnection of Lots of Links (TRILL), pour connecter les différents éléments de notre architecture C-RAN. La seconde solution, consistera à déployer un réseau Software Defined Network (SDN), géré par le contrôleur distribué ONOS, qui sera virtualisé dans le pool BBU. Une comparaison des performances réseau sera réalisée entre ces deux solutionsOver the next five years, the new generation of mobile networks (5G) would face a significant growth of the data volume, exchanged between billions of connected objects and applications. Furthermore, the emergence of new technologies, such as Internet of Things (IoT), autonomous driving and augmented reality, imposes higher performance and quality of service (QoS) requirements. Meeting these requirements, while reducing the Capital and Operation Expenditures (CAPEX/OPEX), are the pursued goals of the mobile operators. Consequently, Telcos define a new radio access architecture, called Cloud Radio Access Network (C-RAN). The C-RAN principle is to centralize, within a pool, the processing unit of a radio interface, named BaseBand Unit (BBU). These two units are interconnected through a Fronthaul (FH) network. In this thesis, we design a new partially centralized C-RAN architecture that integrates a virtualization platform, based on a Xen environment, called Metamorphic Network (MNet). Through this architecture, we aim to: i) implement a pool in which physical resources (processors, memory, network ports, etc.) are shared between virtualized BBUs and other applications; ii) establish an open FH network that can be used by multiple operators, service providers and third parties to deploy their services and Apps closer to the users for a better Quality of Experience (QoE); iii) exploit, through the FH, the existing Ethernet infrastructures to reduce CAPEX/OPEX; and finally iv) provide the recommended network performance for the 5G. In the first contribution, we define a new Xen architecture for the MNet platform integrating the packet-processing framework, OpenDataPlane (ODP), within a privileged Xen domain, called Driver Domain (DD). This new architecture accelerates the data packet processing within MNet, while avoiding the physical CPUs overuse by ODP. Thus, virtual CPU cores (vCPU) are allocated within DD and are used by ODP to accelerate the packet processing. This new Xen architecture improves the MNet platform by 15%. In the second contribution, we implement two network solutions within the FH. The first solution consist of deploying a layer 2 network protocol, Transparent Interconnection of Lots of Links (TRILL), to connect multiple elements of our C-RAN architecture. The second solution consists of implementing a Software Defined Network (SDN) model managed by Open Network Operating System (ONOS), a distributed SDN controller that is which is virtualized within BBU pool. Moreover, a network performance comparison is performed between these two solutions

La combustió dels combustibles fòssils ha causat problemes mediambientals i energètics a nivell mundial, la qual cosa influeix en la salut i les activitats humanes. Amb la motivació de contribuir per resoldre aquests problemes, hem realitzat una sèrie de recerques per explorar materials i molècules per a la generació d'energia lliure de contaminació, com és l'energia solar convertida en hidrogen que proposa aquesta tesi. Hem analitzat estadísticament les partícules contaminants en l'aire, partícules de PM2.5, les quals indiquen que els agregats de sutge rics en carboni mostren una adhesividad i agregació molt altes. Més del 50% de les partícules PM2.5 interactuen fortament amb el substrat generant una capa molt prima (<10 nm) la qual és molt estable (fins i tot sota estrès mecànic) i que està composta de metalls alcalins, hidrogen i grups CH. Després de l'estudi sobre partícules contaminants en l'aire, ens hem centrat en l'estudi de dispositius de divisió d'aigua mitjançant radiació solar per explorar la generació d'hidrogen a gran escala. En aquesta tesi, ens hem centrat principalment en la recerca de materials i molècules per a divisors de molècules d'aigua fotoelectroquímics (PEC) i fotovoltaic-electrolítics (PV-EC). Els nostres resultats mostren que en els dispositius PEC, poden dipositar-se en la superfície dels foto-ànodes de silici pel·lícules primes metàl·liques de coure i níquel, podent formar CuO i NiOX respectivament. Tots dos materials actuen com a catalitzadors molt actius per a la reacció d'oxidació d'aigua i alhora com una capa protectora de la corrosió per a superfície de silici. D'altra banda, els dispositius PV-EC, pels quals hem utilitzat un ànode basat en molècules catalizadoras de Ruteni, s'ha integrat amb cèl·lules solars d'unió triple. Aquests dispositius han aconseguit una eficiència màxima de conversió energia solar-hidrogen del 21,2% a pH neutre i just per sota de la il·luminació solar sense cap polarització externa. Aquests resultats contribueixen a la generació d'hidrogen per conversió solar a gran escala.La combustión de los combustibles fósiles ha causado problemas medioambientales y energéticos a nivel mundial, lo que influye en la salud y las actividades humanas.

The combustion of the fossil fuels has caused the global environment and energy problems, which influences human health and activities. With the motivation to make our contributions to solving these problems, we have performed a series of investigations to explore materials and molecules for pollution free clean energy, which is solar energy converted hydrogen in this thesis. We have statistically analyzed the airborne pollutant particles, PM2.5 particles, which indicates that the carbon-rich fluffy soot aggregates always show very high adhesiveness and aggregation. And more than 50% PM2.5 particles strongly interact with the substrate through a ultra-thin (< 10 nm) dark trace layer, which is very stable even under mechanical stress and it is consisted of alkali metals, hydrogen and CH groups. After the study about airborne pollutant particles, we have moved to the study of solar-driven water splitting devices for exploring the large-scale generation of hydrogen. In this thesis, we have mainly focused on the investigation of the materials and molecules for photoelectrochemical (PEC) and photovoltaic-electrolysis (PV-EC) water splitting devices. Our results show that in the PEC water splitting devices, copper and nickel metallic thin films can be deposited on the surface of silicon photoanodes, which can form CuO and NiOX respectively and then serve as very active catalysts for water oxidation reaction and a protecting layer for silicon surface from corrosion. And in PV-EC water splitting devices, the ruthenium molecular catalysts based anode has been used for the electrolyzer, which has been integrated with commercially available triple junction solar cells. This integrated PV-EC device achieves the highest solar-to-hydrogen efficiency of 21.2 % at neutral pH and just under solar illumination without any external bias. These results pave the way for the generation of large-scale solar converted hydrogen.

Cette étude théorique est pensée en lien étroit avec un champ d'application : il s'agit de modéliser la croissance d'une population de cellules qui se divisent selon un taux de division inconnu, fonction d’une variable dite structurante – l’âge et la taille des cellules étant les deux exemples paradigmatiques étudiés. Le champ mathématique afférent se situe à l'interface de la statistique des processus, de l’estimation non-paramétrique et de l’analyse des équations aux dérivées partielles. Les trois objectifs de ce travail sont les suivants : reconstruire le taux de division (fonction de l’âge ou de la taille) pour différents schémas d’observation (en temps généalogique ou en temps continu) ; étudier la transmission d'un trait biologique général d'une cellule à une autre et étudier le trait d’une cellule typique ; comparer la croissance de différentes populations de cellules à travers le paramètre de Malthus (après introduction de variabilité dans le taux de croissance par exemple)This work is concerned with growth-fragmentation models, implemented for investigating the growth of a population of cells which divide according to an unknown splitting rate, depending on a structuring variable – age and size being the two paradigmatic examples. The mathematical framework includes statistics of processes, nonparametric estimations and analysis of partial differential equations. The three objectives of this work are the following : get a nonparametric estimate of the division rate (as a function of age or size) for different observation schemes (genealogical or continuous) ; to study the transmission of a biological feature from one cell to an other and study the feature of one typical cell ; to compare different populations of cells through their Malthus parameter, which governs the global growth (when introducing variability in the growth rate among cells for instance)

Storing and processing big data in local premises is increasingly inconvenient, but resorting to cloud storage and processing raises security and privacy issues. We tackle here the problem of outsourcing to untrusted clouds in a practical and privacy-preserving manner two basic operations on non-encrypted sensitive data: scalar products and matrix products. These operations are useful to perform data analyses such as correlations between attributes or contingency tables, among others. Our protocols allow using the cloud not only to store sensitive non-encrypted data, but also to process them. In addition to analyzing the security of the proposed protocols, we also evaluate their performance against a baseline consisting of downloading plus local computation. The experiments on categorical data that we report on the Amazon cloud service show that, with our protocols, the data controller can save more than 99.999% runtime for the most demanding computations. We also present here a methodology to compare statistical disclosure control (SDC) methods for microdata in terms of how they perform regarding the risk-utility trade-off. Previous comparative studies usually start by selecting some parameter values for a set of SDC methods and evaluate the disclosure risk and the information loss yielded by the methods for those parameterizations. In contrast, here we start by setting a certain risk level and then we find which parameter values are needed to attain that risk under different SDC methods. Finally, we evaluate the utility provided by each method, in order to rank methods according to their utility preservation.

Seismic anisotropy at continental regions, mainly at stable areas, gives important information about past and present tectonic events, and helps us in understanding patterns of upper mantle flow in a way not achieved by other methods. The measurement of shear wave splitting (SWS), at individual stations, from core refracted phases (such as SKS phases), indicates the amount and orientation of the seismic anisotropy in the upper mantle. Previous studies of SWS in South America concentrated mainly along the Andes and in southeast Brazil. Now we add extra measurements extending to all Brazilian territory, especially in the Pantanal and Paraná-Chaco basins, as part of the FAPESP 3-Basins Thematic Project. The results from both temporary deployments and from the Brazilian permanent network provide a more complete and robust anisotropy map of the South America stable platform. In general the fast polarization orientations have an average E-W orientation. Significant deviations to ESE-WNW or ENE-WSW are observed in many regions. We compare our results with different anisotropy proxies: absolute plate motion given by the hotspot reference frame HS3-NUVEL-1A, a recent model of time dependent upper mantle flow induced by the Nazca plate subduction, global anisotropy from surface wave tomography, and geologic trends. We observe a poor correlation of the anisotropy directions with geological trends, with the exception of a few stations in northern Brazil and a better correlation with the mantle flow model. Therefore, our observed anisotropy is mainly due to upper-mantle flow, with little contribution from frozen lithospheric anisotropy. Also, deviations from the mantle flow model, which includes a thicker lithosphere at the Amazon craton, are mainly due to flow surrounding cratonic nuclei not used in the model: the keel of the São Francisco craton and a possible cratonic nucleus beneath the northern part of the Paraná Basin (called Paranapanema block). Large delay times at the Pantanal Basin may indicate a stronger asthenospheric channel, a more coherent flow, or a thicker asthenosphere. Small delays beneath the northern Paraná Basin and central Amazon craton may indicate thinner anisotropic asthenosphere.Anisotropia sísmica em regiões continentais, principalmente em áreas estáveis, nos dá informações importantes sobre eventos tectônicos do passado e do presente, e nos ajuda a entender padrões de fluxo do manto superior de forma não alcançada por outros métodos geofísicos. A medida de separação de ondas cisalhantes (SWS), em estações individuais, de fases refratadas no núcleo (fases SKS, por exemplo), indica a intensidade e orientação da anisotropia sísmica no manto superior. Estudos prévios de SWS na América do Sul se concentraram principalmente ao longo dos Andes e no sudeste do Brasil. Agora adicionamos medidas extras que se extendem por todo território Brasileiro e alguns países vizinhos, especialmente nas bacias do Pantanal e do Chaco-Paraná, como parte do \"Projeto Temático 3-Bacias\" da FAPESP. Os resultados tanto das estações temporárias quanto da rede permanente Brasileira mostram um mapa de anisotropia mais robusto e completo da plataforma estável da América do Sul. Em geral, as direções de polarização rápida tem em média direção L-O. Desvios significantes nas direções LSL-ONO ou LNL-OSO são observadas em muitas regiões. Comparamos nossos resultados com diferentes representantes da anisotropia: movimento absoluto de placa dado pelo sistema de referência de hotspot HS3-NUVEL-1A, um modelo recente dependente do tempo de fluxo do manto superior induzido pela subducção da placa de Nazca, anisotropia global de tomografia de ondas de superfície, e tendências geológicas. Observamos pouca correlação das direções de anisotropia com tendências geológicas, com exceção de algumas estações no norte do Brasil e uma melhor correlação com o modelo de fluxo do manto. Portanto, nossa anisotropia observada é devida principalmente a fluxo do manto superior, com pouca contribuição de anisotropia \"congelada\" litosférica. Também, desvios do modelo de fluxo do manto, o qual inclui uma litosfera mais espessa no cráton da Amazônia, são devido ao fluxo ao redor de núcleos cratônicos não usados no modelo: a quilha do cráton do São Francisco e um possível núcleo cratônico abaixo da região norte da bacia do Paraná (chamado bloco do Paranapanema). Atrasos de tempo grandes na bacia do Pantanal podem indicar um canal astenosférico mais forte, um fluxo mais coerente ou uma astenosfera mais espessa. Pequenos atrasos abaixo da parte norte da bacia do Paraná e no centro do cráton da Amazônia podem indicar uma astenosfera mais fina.

This thesis deals with the dividing the dictionary entry into several "sub-meanings", i.e. with the sense division, and with the closely related ordering of these "sub-meanings", i.e. with the sense ordering, with the bilingual passive German-Czech dictionary in the centre of interest. This thesis deals shortly also with the discriminating the senses by different means, i.e. with the sense discrimination. With these three subjects chronologically following the lexicographic decisions the matter of equivalence and the understanding of the term of meaning are correlated. In the theoretical part of this thesis the specifics of the sense division and the sense ordering in the monolingual and in the bilingual lexicography are introduced, in the practical part of this thesis the possibilities of the sense division and the sense ordering are exemplified with ten chosen substantive lemmas prepared for the Large German-Czech Academic Dictionary in progress. For every lemma the most suitable arrangement of the lemma is suggested, which is then compared with the corresponding dictionary entry in the source dictionary Duden - Deutsches Universalwörterbuch. The differences between the arrangements of the microstructure illustrate the necessity of the revision and eventual modification of the adopted structure...

Full textAbstract:
This chapter presents results about a residually pseudo-split Bruhat-Tits building ΞL. It begins with a case for some quadratic space of type E⁶, E₇, and E₈ in order to identify an unramified extension such that the residue field is a pseudo-splitting field. It then considers a wild quaternion or octonion division algebra and the existence of an unramified quadratic extension L/K such that L is a splitting field of the quaternion division algebra. It also discusses the properties of an unramified extension L/K and shows that every exceptional Bruhat-Tits building is the fixed point building of a strictly semi-linear descent group of a residually pseudo-split building.

This chapter presents performance of a new technique for constructing Quasi-Cyclic Low-Density Parity-Check (QC-LDPC) encrypted codes based on a row division method. The new QC-LDPC encrypted codes are flexible in terms of large girth, multiple code rates, and large block lengths. In the proposed algorithm, the restructuring of the interconnections is developed by splitting the rows into subrows. This row division reduces the load on the processing node and ultimately reduces the hardware complexity. In this method of encrypted code construction, rows are used to form a distance graph. They are then transformed to a parity-check matrix in order to acquire the desired girth. In this work, matrices are divided into small sub-matrices, which result in improved decoding performance and reduce waiting time of the messages to be updated. Matrix sub-division increases the number of sub-matrices to be managed and memory requirement. Moreover, Prototype architecture of the LDPC codes has been implemented by writing Hardware Description Language (VHDL) code and targeted to a Xilinx Spartan-3E XC3S500E FPGA chip.

Wireless Power Transfer is a promising solution to increase the lifetime of wireless nodes and hence alleviate the energy bottleneck of energy constrained wireless networks. In this Chapter, we discuss two power transfer policies; dual-source and single fixed-source, two bidirectional relaying protocols; multiple access and time division broadcast, and two relay receiver structures; time switching and power splitting, are considered to derive closed-form expressions for the outage and throughput of the network in the context of delay-limited transmission. This framework assists the reader not only to quantify the degradation of outage probability and throughput of the networks due to the impairments of realistic transceiver but also to provide realistic insight into the effect of power transfer policies, relaying protocols and receiver structures on outage and throughput of the networks.

This article deals with the foundation of the Communist Party of Britain (CPB), a 1988 split from the Communist Party of Great Britain (CPGB), which was overseen by a group around Tony Chater, whom had earlier been involved with splitting the Morning Star newspaper away from the CPGB. The CPB was unsuccessful in uniting its preferred constituency, party trade unionists; and appears to have alienated many CPGB oppositionists due to its tactics and agitation for a split. It did manage to group together wider layers of people who had been oppositionists in the old CPGB as the 1990s wore on but, by the middle of the decade, this process had pushed initial leadership figures such as Mike Hicks, Mary Rosser and others into hostility towards those who were perceived to have been oppositional rivals in the 1980s. Thus, the divisions in the CPGB at the foundation of the CPB cast a long political shadow.

Code for analysis of the water hammer in thermal-hydraulic systems is being developed within the WAHALoads project founded by the European Commission [1]. Code will be specialized for the simulations of the two-phase water hammer phenomena with the two-fluid model of two-phase flow. The proposed numerical scheme is a two-step second-order accurate scheme with operator splitting; i.e. convection and sources are treated separately. Operator splitting technique is a very simple and “easy-to-use” tool, however, when the source terms are stiff, operator splitting method becomes a source of a specific non-accuracy, which behaves as a numerical diffusion. This type of error is analyzed in the present paper.

Full textAbstract:
Nickel-based austenitic weldments are widely used in steam generator, however it’s difficult for inspection because of its inhomogeneous and anisotropic elastic behaviors. The anisotropic and heterogeneous characteristics of austenitic welds together with a coarse-grained structure (elongated and oriented grains) lead to the following phenomena: scattering, attenuation, skewing, splitting, and divergence of the ultrasonic beam. To improve the ultrasonic inspection, beam behavior in weld need to be understood theoretically and experimentally. For that purpose, water immersed C-scans have been performed with respect to different parts (base material, austenite weld) of the weldments using one 5MHz transducer as transmitter at one side of the specimen and one 5MHz pinducer on the other side as receiver. Beam skewing and splitting is observed, 2D FFT are performed to obtain scan image in frequency domain and echodynamic curve is extracted from the C-scan data. The experiments results are also compared with the simulation results using multi-Gaussian beam model.

Full textAbstract:
A simplified model is proposed to predict the flow in a Steam Injector (SI), based on the splitting in successive two phase flow processes. SI experimentations have been carried out including pressure and void fraction measurements. The results show that the model provides good values of flow rates and pressures inside the device and describes well its behavior. It will have to be enriched with dissipative processes, mainly friction in the mixing chamber and dissipation in the condensation shock in order to achieve the prediction of the outlet pressure that can reach more than 4 or 5 times the steam feeding pressure.

Full textAbstract:
Microchannel heat sinks (MCHS) are explored as integrated cooling option in diversified applications ranging from microelectronic devices to nuclear reactors. Parallel channel MCHS suffers from the problem of flow maldistribution in channels. The phenomenon of flow maldistribution causes undesired effects such as non-uniform temperature distribution, increase in base maximum temperature and drop in MCHS performance. In the present single phase numerical study; flow maldistribution in vertical supply MCHS has been estimated by taking entire heat sink as computational domain. Three-dimensional governing equations for both fluid flow and energy transfer are solved by finite volume method. A novel heat sink design by splitting the inlet flow in two equal parts has been proposed to effectively reduce flow maldistribution problem in MCHS. Results of velocity distribution, temperature distribution of fluid and overall thermal performance of proposed MCHS are compared with the conventional MCHS design. Proposed scheme helps in reducing flow maldistribution problem significantly (∼55%) as compared to conventional MCHS.

Full textAbstract:
This paper studies the effect of the electrode aspect ratio on droplet splitting in a digital microfluidics (DMF) chip including an array of 3 electrodes in which the middle electrode is kept square while the two side electrodes have different aspect ratios. The aspect ratio is changed from 0.9 to 1.3 while the surface area of the electrodes is kept constant for all cases. Results show that changing the aspect ratio can severely change the required voltage for splitting with a nonlinear behavior. It is also shown that for a constant gap between the top and bottom plates and a constant volume of the droplet, the relation between the threshold voltage and the aspect ratio is parabolic, for which there is an aspect ratio with a minimum threshold voltage. Changing the volume of the droplet changes the threshold voltage and hence the aspect ratio corresponding to the minimum threshold voltage required for splitting.

Full textAbstract:
The ‘Discrete Particle Method’ (DPM) is a versatile numerical tool for improving the understanding of particle flows behavior on a meso-scopic level. A crucial point when using the DPM is the CPU-time consumption for detection of particle collisions. An adaptive algorithm for efficient particle-particle and particle-wall collision detection in a two-dimensional case is presented. The physical domain is hierarchically divided and structured as a quadtree. The algorithm ensures an efficient computation of colliding particle flows by splitting and merging the cells between each time step to keep the number of particles within a proposed range. The numerical performance of the adaptive algorithm is studied by simulating a flow particle in a 90° bend. The computational time of the adaptive algorithm is compared with the simulations performed with a uniform fixed cell structure with optimal size. The adaptive algorithm seems to be mostly advantageous in flows where the particles are not uniformly distributed, in complex geometries, and otherwise where information about the optimal cell size is not known a priori.
