The clean water tank discussed consists of four reinforced concrete tanks. The structure is symmetrical for each of the tank pairs, which consist of two storage tanks and two water transfer tanks for the water supply network. All chambers are technologically connected with each other. The tanks are partially recessed in the ground, monolithic, and completely roofed. The projection of chambers within external walls is 96 x 96 m = 9,216 m2. The total capacity of internal chambers and external chambers is about 45,000 m3. The clean water tank was made as a reinforced concrete structure, monolithic. The owner of the facility observed significant losses of stored water, which translated into large financial losses of the company. In order to determine the current technical condition of the reservoir and the causes of its leakage, a comprehensive, multi-level analysis was carried out in terms of strength, stability and durability of the structure. A few dozens of samples were taken at random, and the compressive strength of the concrete, modulus of longitudinal deformation and degree of carbonatization were evaluated. For the assessment of the technical condition of the expansion joints, boreholes were also drilled through them. On the basis of the results obtained from the tests, numerical analysis of the stress on the structure and its deformations was performed in order to select the most stressed areas as well as to assess expansion deformations as potential spots of the largest leaks. The results of the analysis were used to prepare the concept of sealing repairs of the tank chambers.

Abstract The article presents the results of validation of static calculations carried out for a monolithic rectangular tank with walls of trapezoidal cross-section. Static calculations were made with the use of software based on the finite element method (FEM) and the finite difference method (FDM) in terms of energy (including spatial static work of the tank). Validation of the results was conducted on a concrete tank model using an innovative measurement tool, i.e. a coordinate measuring arm with a touch probe.

Full textAbstract:
The exploitation time and reliability of monolithic reinforced concrete structures largely depend on concreting technology and process influence during concreting and early setting stages. Different types of cracks in monolithic reinforced concrete structures appear due to internal and external effects. Cracks appear when the technology of structure concreting is damaged, when formwork is removed during the further setting and structures loaded period. In order to avoid micro and macro cracks in monolithic structures, it is important to measure the particular setting time moment and technological process moment when stresses that exceed the permissible values appear in concrete. The article analyses the processes that appear when horizontal, sloping and vertical monolithic reinforced concrete structures are concreted. The analysis of concrete mixture pressure on formwork is performed. The pressure which is calculated according to different countries’ methodology is different: the smallest pressure is obtained calculating according to the British recommendations, and the largest pressure is obtained according to French CIB recommendations. In Lithuania, it is recommended to follow the German DIN 18218 standard. The balance conditions of concrete mixture concreting on slope surface are described. The main concreting technology parameters and their interaction are analysed; the speed, intensity and time of continuous concreting technology are presented. When the process of continuous concreting is performed, it is necessary to evaluate the interaction and values of parameters properly. Methodical theoretical calculation is presented. Practical solutions for industrial building construction applying the modern sliding formwork technology are presented. The impact of cement type, superplasticizers and temperature over the concrete mixture mobility, changes, fresh concrete structural strength and concrete setting kinetics are analysed. The main characteristics of the initial setting — the beginning of structure formation, when concrete mixture turns into concrete state — is analysed applying the ultrasonic method. The beginning of structure formation influences the regulated time of concrete mixture laying and compaction. The requirements for structural strength (permissible strength limits) and concreting rate (formwork movement) of freshly formed concrete are set when the construction is performed applying the continuous concreting technology method. The analysis is implemented performing the construction of cylindrical sludge tank with slipping formwork. While performing the analysis during concreting, it was stated that the concrete setting kinetics corresponds to the sludge tank concreting rate. The analysis performed after concreting and in 28 days of hardening revealed that there are no surface defects or cracks, and concrete strength exceeds the required sludge tank design strength.

Full textAbstract:
Septic tank systems have been widely used to separate and digest solid matter in the household wastewater for a long time. However, they contaminate groundwater with pathogens and nutrients and deprive agriculture of valuable nutrients and soil conditioner from human excreta. Compared with septic tank systems the filter–composter (Rottebehaelter), which usually consists of an underground monolithic concrete tank having two filter beds at its bottom or two filter bags that are hung side by side and used alternately at intervals of 6–12 months, is an efficient component for solid–liquid separation, pre-treatment and collection/storage of solid matter in household wastewater. The solids are retained and decompose in the filter bags or on the filter bed while the liquid filters through. However, because of the high moisture content of the retained solids decomposition is slow. Therefore, secondary treatment of the retained solids is required for sanitisation. The breakthrough was the combination of vermicomposting with the filter-composter system. Relatively dry and stable retained materials were obtained in the filter bags in about 3 months only. No secondary treatment is required as the human excreta will be converted to vermicastings, which are hygienically safe and can be reused as soil conditioner. Therefore, further development of the filter–composter with vermicomposting is worthwhile, especially the aspects of sanitisation of the faecal matter and its reuse as a soil conditioner.

Full textAbstract:
This work presents a one-dimensional reactor model for a tubular reactor packed with a catalytically active foam packing with a pore density of 30 PPI in cocurrent upward flow in the example of hydrogenation reaction ofα-methylstyrene to cumene. This model includes material, enthalpy, and momentum balances as well as continuity equations. The model was solved within the parameter space applied for experimental studies under assumption of a bubbly flow. The method of orthogonal collocation on finite elements was applied. For isothermal and polytropic processes and steady state conditions, axial profiles for concentration, temperature, fluid velocities, pressure, and liquid holdup were computed and the conversions for various gas and liquid flow rates were validated with experimental results. The obtained results were also compared in terms of space time yield and catalytic activity with experimental results and stirred tank and also with random packed bed reactor. The comparison shows that the application of solid foams as reactor packing is advantageous compared to the monolithic honeycombs and random packed beds.

Full textAbstract:
Porous adsorbents are currently investigated for hydrogen storage application. From a practical point of view, in addition to high porosity developments, high material densities are required, in order to confine as much material as possible in a tank device. In this study, we use different measured sample densities (tap, packing, compacted and monolith) for analyzing the hydrogen adsorption behavior of activated carbon fibres (ACFs) and activated carbon nanofibres (ACNFs) which were prepared by KOH and CO2 activations, respectively. Hydrogen adsorption isotherms are measured for all of the adsorbents at room temperature and under high pressures (up to 20 MPa). The obtained results confirm that (i) gravimetric H2 adsorption is directly related to the porosity of the adsorbent, (ii) volumetric H2 adsorption depends on the adsorbent porosity and importantly also on the material density, (iii) the density of the adsorbent can be improved by packing the original adsorbents under mechanical pressure or synthesizing monoliths from them, (iv) both ways (packing under pressure or preparing monoliths) considerably improve the storage capacity of the starting adsorbents, and (v) the preparation of monoliths, in addition to avoid engineering constrains of packing under mechanical pressure, has the advantage of providing high mechanical resistance and easy handling of the adsorbent.

The article is devoted to the general patterns of political parties formation in Russia at the beginning of the 20th century. They were preceded by proto-party organizations that were far from being ideologically monolithic. Under the conditions of rapid differentiation of political forces, the existing alliances were often accidental and situational. They hung on to the legacy of the pre-revolutionary era, when the public was just “learning” to talk about politics, and the boundaries between different ideological structures were quite rather relative.

Full textAbstract:
Les technologies logicielles ne cessent d'évoluer pour faciliter le développement, le déploiement et la maintenance d'applications dans différents domaines. En parallèle, ces applications évoluent en continu pour garantir une bonne qualité de service et deviennent de plus en plus complexes. Cette évolution implique souvent des coûts de développement et de maintenance de plus en plus importants, auxquels peut s'ajouter une augmentation des coûts de déploiement sur des infrastructures d'exécution récentes comme le cloud. Réduire ces coûts et améliorer la qualité de ces applications sont actuellement des objectifs centraux du domaine du génie logiciel. Récemment, les microservices sont apparus comme un exemple de technologie ou style architectural favorisant l'atteinte de ces objectifs.Alors que les microservices peuvent être utilisés pour développer de nouvelles applications, il existe des applications monolithiques (i.e., monolithes) cons-truites comme une seule unité et que les propriétaires (e.g., entreprise, etc.) souhaitent maintenir et déployer sur le cloud. Dans ce cas, il est fréquent d'envisager de redévelopper ces applications à partir de rien ou d'envisager une migration vers de nouveaux styles architecturaux. Redévelopper une application ou réaliser une migration manuellement peut devenir rapidement une tâche longue, source d'erreurs et très coûteuse. Une migration automatique apparaît donc comme une solution évidente.L'objectif principal de notre thèse est de contribuer à proposer des solutions pour l'automatisation du processus de migration d'applications monolithiques orientées objet vers des microservices. Cette migration implique deux étapes : l'identification de microservices et le packaging de ces microservices. Nous nous focalisons sur d'identification en s'appuyant sur une analyse du code source. Nous proposons en particulier deux approches.La première consiste à identifier des microservices en analysant les relations structurelles entre les classes du code source ainsi que les accès aux données persistantes. Dans cette approche, nous prenons aussi en compte les recommandations d'un architecte logiciel. L'originalité de ce travail peut être vue sous trois aspects. Tout d'abord, les microservices sont identifiés en se basant sur l'évaluation d'une fonction bien définie mesurant leur qualité. Cette fonction repose sur des métriques reflétant la "sémantique" du concept "microservice". Deuxièmement, les recommandations de l'architecte logiciel ne sont exploitées que lorsqu'elles sont disponibles. Enfin, deux modèles algorithmiques ont été utilisés pour partitionner les classes d'une application orientée objet en microservices : un algorithme de regroupement hiérarchique et un algorithme génétique.La deuxième approche consiste à extraire à partir d'un code source orienté objet un workflow qui peut être utilisé en entrée de certaines approches existantes d'identification des microservices. Un workflow décrit le séquencement de tâches constituant une application suivant deux formalismes: un flot de contrôle et/ou un flot de données. L'extraction d'un workflow à partir d'un code source nécessite d'être capable de définir une correspondance entre les concepts du mon-de objet et ceux d'un workflow.Pour valider nos deux approches, nous avons implémenté deux prototypes et mené des expérimentations sur plusieurs cas d'étude. Les microservices identifiés ont été évalués qualitativement et quantitativement. Les workflows obtenus ont été évalués manuellement sur un jeu de tests. Les résultats obtenus montrent respectivement la pertinence des microservices identifiés et l'exactitude des workflows obtenusSoftware technologies are constantly evolving to facilitate the development, deployment, and maintenance of applications in different areas. In parallel, these applications evolve continuously to guarantee an adequate quality of service, and they become more and more complex. Such evolution often involves increased development and maintenance costs, that can become even higher when these applications are deployed in recent execution infrastructures such as the cloud. Nowadays, reducing these costs and improving the quality of applications are main objectives of software engineering. Recently, microservices have emerged as an example of a technology or architectural style that helps to achieve these objectives.While microservices can be used to develop new applications, there are monolithic ones (i.e., monoliths) built as a single unit and their owners (e.g., companies, etc.) want to maintain and deploy them in the cloud. In this case, it is common to consider rewriting these applications from scratch or migrating them towards recent architectural styles. Rewriting an application or migrating it manually can quickly become a long, error-prone, and expensive task. An automatic migration appears as an evident solution.The ultimate aim of our dissertation is contributing to automate the migration of monolithic Object-Oriented (OO) applications to microservices. This migration consists of two steps: microservice identification and microservice packaging. We focus on microservice identification based on source code analysis. Specifically, we propose two approaches.The first one identifies microservices from the source code of a monolithic OO application relying on code structure, data accesses, and software architect recommendations. The originality of our approach can be viewed from three aspects. Firstly, microservices are identified based on the evaluation of a well-defined function measuring their quality. This function relies on metrics reflecting the "semantics" of the concept "microservice". Secondly, software architect recommendations are exploited only when they are available. Finally, two algorithmic models have been used to partition the classes of an OO application into microservices: clustering and genetic algorithms.The second approach extracts from an OO source code a workflow that can be used as an input of some existing microservice identification approaches. A workflow describes the sequencing of tasks constituting an application according to two formalisms: control flow and /or data flow. Extracting a workflow from source code requires the ability to map OO conceptsinto workflow ones.To validate both approaches, we implemented two prototypes and conducted experiments on several case studies. The identified microservices have been evaluated qualitatively and quantitatively. The extracted workflows have been manually evaluated relying on test suites. The obtained results show respectively the relevance of the identified microservices and the correctness of the extracted workflows

Dispositional Pluralism is more consistent with our dispositions talk than more monolithic views. Our evidence for extrinsic, ungrounded, and non-natural dispositions is comparable to that of intrinsic, grounded, and natural ones. Dispositional Pluralism has wide applicability to various philosophical issues. Secondary qualities, such as colors, can be given a dispositional account. Thinking of character traits as dispositions sheds light on the debate over Dispositionalism Situationism in moral psychology. One can give an account of gender identity as a cluster of behavioral dispositions. Finally, the potentiality of an embryo or a patient is best understood as an extrinsic dispositional property.

Full textAbstract:
In light of the significant role of the United States in international relations, this chapter argues that the conceptualizations and practices of global governance in the United States are far from monolithic. While the scholarly debate has been prolific in producing a better explanation of what global governance is, the US government has not embraced it as a concept, and on the sporadic occasions where governance is used in official speeches or programmes, the term is often linked to good governance practices in other countries, particularly in Africa. From the methodological perspective, this chapter analyses publications and official documents produced in the United States over the past decade. The argument is developed across three sections: an interpretation of governance and global governance in the US; review of the concept of global governance in US government, think tanks, and universities; and an exploration of global governance in US–African relations.

Full textAbstract:
Amid increased secularization, there is new appreciation for the relevance of moderate religion, such as Catholicism, in redirecting the ethical commitments of contemporary society. The postsecular affirmation of the mutual significance of religious and secular resources provides the Church with a renewed opportunity for engagement with public societal issues and for institutional revitalization among Catholics. It requires, however, a dialogue between doctrinal ideas and the increasingly secularized experiences and expectations of Catholics, as well as others. This book examines how the Church negotiates this task. Anchored in the context of American Catholicism, it aims to help the reader understand why Catholicism continues to have relevance, notwithstanding its multiple tensions. Critical here is recognition of the fact that the Church is not a monolithic entity but, instead, is characterized by, and allows, a dynamic interpretive diversity among laity, bishops, and the Vatican. The book presents case analyses and survey data showing how the crosscutting pull of religious and secular currents plays out across a number of contentious societal and intra-Church issues. Among the topics examined are economic inequality, climate change, gay sexuality, divorce and remarriage, women’s ordination, and religious freedom. This inquiry demonstrates the strategies and processes by which tradition and change, authority and autonomy, and doctrinal ideas and secular realities are held together in Catholicism.

Full textAbstract:
In this fresh and fascinating chronicle of Christianity in the contemporary South, historian and minister James Hudnut-Beumler draws on extensive interviews and his own personal journeys throughout the region over the past decade to present a comprehensive portrait of the South’s long-dominant religion. Hudnut-Beumler traveled to both rural and urban communities, listening to the faithful talk about their lives and beliefs. What he heard pushes hard against prevailing notions of southern Christianity as an evangelical Protestant monolith so predominant as to be unremarkable. True, outside of a few spots, no non-Christian group forms more than six-tenths of one percent of a state’s population in what Hudnut-Beumler calls the Now South. Drilling deeper, however, he discovers an unexpected, blossoming diversity in theology, practice, and outlook among southern Christians. He finds, alongside traditional Baptists, black and white, growing numbers of Christians exemplifying changes that no one could have predicted even just forty years ago, from congregations of LGBT-supportive evangelicals and Spanish-language church services to a Christian homeschooling movement so robust in some places that it may rival public education in terms of acceptance. He also finds sharp struggles and political divisions among those trying to reconcile such Christian values as morality and forgiveness—the aftermath of the mass shooting at Charleston’s Emanuel A.M.E. Church in 2015 forming just one example. This book makes clear that understanding the twenty-first-century South means recognizing many kinds of southern Christianities.

This chapter describes the design and the optimization of Quadrature Voltage Controlled Oscillators (QVCOs) based on the coupling of two LC-tank VCO. This work covers the phase noise analysis, a graphical optimization approach, already used to optimize LC oscillator phase noise (Andreani, Bonfanti, Romano, & Samori, 2002), to optimize QVCO phase noise while satisfying design constraints such as power dissipation, tank amplitude, tuning range and start up condition. The cross-coupling transistors impact on phase noise for different configurations is especially addressed. The obtained BS-QVCO, using 0.35µm CMOS process, can be tuned between 2.2GHz and 2.58GHz, and shows a phase noise of -129 dBc/Hz at 1MHz offset from a 2.4 GHz carrier, for a current consumption of 9.25mW. The equivalent phase error and amplitude error between I and Q signals are respectively 0.65° and 1.87%.

Full textAbstract:
The modern wireless communication industry is demanding transceivers with a high integration level operating in the gigahertz frequency range. This, in turn, has prompted intense research in the area of monolithic passive devices. Modern fabrication processes now provide the capability to integrate onto a silicon substrate inductors and capacitors, enabling a broad range of new applications. Inductors and capacitors are the core elements of many circuits, including low-noise amplifiers, power amplifiers, baluns, mixers, and oscillators, as well as fully-integrated matching networks. While the behavior and the modeling of integrated capacitors are well understood, the design of an integrated inductor is still a challenging task since its magnetic behavior is hard to predict accurately. As the operating frequency approaches the gigahertz range, device nonlinearities, coupling effects, and skin effect dominate, making difficult the design of critical parameters such as the self-resonant frequency, the quality factor, and self and mutual inductances. However, despite the parasitic effects and the low quality-factor, integrated inductors still allow for the implementation of integrated circuits with improved performances under low supply voltage. In this chapter, the authors review the technology behind monolithic capacitors and inductors on silicon substrate for high-frequency applications, with major emphasis on physical implementation and modeling.

Full textAbstract:
Arab identity is an intriguing conundrum. It is commonly presumed that Arabs originated as a distinct and essentially homogenous community of ancient Arabian Bedouin who were separate from other populations of the Middle East, yet modern Arab identity is multifarious and resists all scholarly attempts to generalise about Arabness. It thus seems that pre-modern Arabs are too simplistically conceptualised around monolithic stereotypes of Arabian nomadism, and the idea of ancient Arab identity is accordingly in need of new, theoretically grounded and critical scrutiny. The task inspires this book, and the Introduction sets the scene by discussing the problems of interpreting Arab history, and describes the theoretical models that can help resolve these problems. Ancient Arabs have not hitherto been studied as an ethnic group, and the Introduction discusses how anthropological theories of ethnogenesis enable fresh interpretation of textual and archaeological evidence to reorient our understanding of both Arab origins and the rise of Islam.

Full textAbstract:
‘Mothers and Others’ discusses two recent films, exploring the figure of the Gothic m/other as a continuing site of textual absence and/or excessive abjection. Drawing on Kristevan and Irigarayan theory, it argues that both Ridley Scott’s Prometheus (2012), and Lynne Ramsay’s We Need to Talk About Kevin (2011) are examples of a post-feminist Gothic that articulates contemporary anxieties about the increasingly engineered medicalisation and judgemental cultural monitoring of mothering/mothers. Prometheus, prequel to the Alien quadrilogy, repeatedly absents the mother in its postulation of a male creationist myth and the uncanny textual space opened up by its anterior-yet-posterior relationship to its predecessors is overwritten by the predictable effects of penetrative body-horror: the mother as monstrous other is driven beyond the edges of the text. In contrast to this absenting of the mother, We Need to Talk About Kevin is saturated with motherly presence. The tropes of Gothic horror are used to convey a sense of mothering as violent self-erasure and the mother as potential progenitor of an uncontainable monstrous Other. However, the film uses repeated mirrorings of Eva and Kevin that imply a haunting pre-Symbolic bond that persists in troubling a monolithic reading of the developing mother/son dyad.

This book chapter presents the integration of widely available technologies to bridge the gap between mobile devices and their computational rich surrounding environments. Taking as common glue Cloud Storage systems, new interaction between devices becomes more natural. The processing of files can be transparently executed on nearby computers, taking advantage of better hardware and saving mobile devices power. In this chapter, the authors present a novel resource evaluation mechanism, which allows a finer evaluation and more precise comparison of remote resources, leading to fewer wasted resources and better use of those resources. The use of remote resources can be performed by means of processing offloading, executing complete application on remote devices or by relocation of mobile classes. Both methods resort to the presented resource evaluation mechanism. Monolithic applications are transformed (with information from a configuration file) into distributed application, where some components execute on remote devices: nearby computers (to take advantage of existing human-computer interaction devices) or on the cloud (to speed processing). Processing offloading is accomplished by executing on nearby computers applications compatible with the one on the mobile device. This speeds that processing task (better CPU, better interaction devices), reducing the mobile device’s power consumption.

Though the Periodic table has been a centerpiece of chemistry since the 1870s, it is in recent years that a more detailed study of patterns and trends has become of interest. In part, this study reflects the accumulated wealth of data on comparative formulas, structures, and properties of compounds across the periodic table. Traditionally, patterns in the periodic table have been examined through defined criteria of groups and periods. Such a mindset immediately obscures other linkages. I have previously critically analyzed and extended nontraditional connections. Such connections have been . . . Isoelectronic: similarities between species (molecules or ions) which have the same total number of electrons and of valence electrons together with the same structure (number and connectivity of atoms); Isodiagonal: similarities between an element of group (n) and period (m) with an element of group (n+1) and period (m+1). Knight’s move: similarities between an element of group (n) and period (m) with the element in group (n+2) and period (m+1) in the same oxidation state (in the lower-right of the periodic table); Group (n) and (n+10): similarities between elements of Group (n) with elements of Group (n+10) in the same highest oxidation state. . . . It is such other, less-obvious patterns that enrich the study of the elements and lead to additional possibilities for exploration. Here, we will deconstruct the monolithic block of transition metals and see how assigning an element to a specific cluster provides a more flexible approach to appreciating the complexity of the transition series than simple use of group or period assignment. The first task is to define the transition metals, which is not quite as obvious as it may seem. The main group elements are always identified as the members of groups 1–2, and 13–18. In addition, about half of sources include group 12. One might justifiably conclude, therefore that groups 3–11 or 3–12 would be the transition metals. However, identifying a “transition metal” is not simply a question of location in the periodic table, but also one of chemical behavior.

Full textAbstract:
NASA has numerous non-code layered pressure vessel (LPV) tanks that hold various gases at pressure. Since replacement costs of the tanks would be high an assessment of the pressure vessels’ capabilities for continued use is desired. Layered tanks typically consists of an inner liner/shell (often about 12.5 mm thick) with different layers of thinner shells surrounding the inner liner each with thickness of about 6.25-mm. The layers serve as crack arrestors for crack growth through the thickness. The number of thinner layers required depends on the thickness required for the complete vessel. All cylindrical layers are welded longitudinally with staggered welds so that the weld heat affected zones do not overlap. The built-up shells are then circumferentially welded together or welded to a header (or nozzle) to complete the tank construction. This paper presents computational weld residual stress (WRS) modeling results of two representative layered tanks; (i) a small 4-layer tank and (ii) a large 14-layer tank. Contact between the layers must be considered which led to some convergence difficulties that were overcome. These predictions are compared with the corresponding monolithic tanks (non-layered) of the same size and thickness along with comparing to some compiled API-579 [1] WRS solutions. In general, the WRS fields in layered tanks are quite different from those in corresponding monolithic tanks and the effect of layering is necessary to include in the modeling. In addition, since the toughness of some aged tanks can be low the effect WRS on cracks may important. This is examined by introducing cracks into the tanks at locations where cracking may occur using the finite element alternating method (FEAM). Comments about the effect of WRS fields on fracture are also made.

Full textAbstract:
This paper presents results from the experimental investigation of single-phase flow in a prototype stirred tank reactor, which uses monolith catalyst blocks as impeller. These monolith catalyst supports have been used for a dual role: (i) as stirrer blades for agitation and (ii) to bring reactants in contact with the catalyst in a way that eliminates the need for product filtration. The reactors are under investigation as replacement for the standard slurry stirred tank reactors used in the catalytic processes in chemical industry. The flow field in the reactor with this novel impeller, was determined using LDA. Mean and fluctuating velocity data were measured for different monolith blocks and impeller speeds. Results show the normalized flow in the bulk of the tank to be independent of impeller speed and monolith type. Flow velocities through the monolith channels, which are crucial to bring the reactants in contact with the catalyst impregnated in the monolith walls, were measured with LDA. These velocities were found to be of the order of 30–70% of the impeller tip velocity, dependent on the impeller speed and monolith type.

In ASME 2010 13th International Conference on Environmental Remediation and Radioactive Waste Management. ASMEDC, 2010. http://dx.doi.org/10.1115/icem2010-40165.
Full textAbstract:
The THOR® fluidized bed steam reforming process has been successfully operated for more than 10 years in the United States for the treatment of low- and intermediate-level radioactive wastes generated by commercial nuclear power plants. The principle waste stream that has been treated is ion exchange resins (IER) and Dry Active Waste (DAW), but various liquids, sludges, and solid organic wastes have also been treated. The principle advantages of the THOR® process include: (a) high volume reduction on the order of 5:1 to 10:1 for IER and up to 50:1 for high plastic content DAW streams depending on the waste type and waste characteristics, (b) environmentally compliant off-gas emissions, (c) reliable conversion of wastes into mineralized products that are durable and leach-resistant, and (d) no liquid effluents for treatment of most radioactive wastes. Over the past ten years, the THOR® process has been adapted for the treatment of more complex wastes including historic defense wastes, reprocessing wastes, and other wastes associated with the fuel cycle. As part of the U.S. Department of Energy (DOE) environmental remediation activities, the THOR® dual bed steam reforming process has successfully processed: (a) Idaho National Laboratory (INL) Sodium-Bearing Waste (SBW), (b) Savannah River Tank 48 High Level Waste (HLW), (c) Hanford Low Activity Waste (LAW), and (d) Hanford Waste Treatment Plant Secondary Waste (WTP-SW) liquid slurry simulants. The THOR® process has been shown in pilot plant operations to successfully process various simulated liquid, radioactive, nitrate-containing wastes into environmentally safe, leach-resistant, solid mineralized products. These mineralized products incorporate normally soluble ions (e.g. - Na, K, Cs, Tc), sulfates, chloride salts, and fluoride salts into an alkali alumino-silicate mineral matrix that inhibits the leaching of those ions into the environment. The solid mineralized products produced by the THOR® process exhibit durability and leach resistance characteristics superior to borosilicate waste glasses. As a result of this work, a full-scale THOR® process facility is currently under construction at the DOE’s Idaho site for the treatment of SBW and a full-scale facility is in the final design stage for the DOE’s Savannah River Site for the treatment of Tank 48 high level waste. Recent work has focused on the development of new monolithic waste formulations, the extension of the THOR® process to new waste streams, and the development of modular THOR® processes for niche waste treatment applications. This paper will provide an overview of current THOR® projects and summarize the processes and outcomes of the regulatory and safety reviews that have been necessary for the THOR® process to gain acceptance in the USA.

Full textAbstract:
Application of engineered ceramic materials in high temperature environments of advanced propulsion systems in high performance aircraft; structural demands in ceramic-composite armor; application of high density polyethylene in piping, and reinforced rubber in nuclear power service; and fiber reinforced resin overwraps for piping, all present demanding nondestructive testing challenges. A new technology, Evisive Scan™, has been recently developed that allows condition monitoring in these challenging materials. The internationally patented Evisive Scan™ method is based on microwave interferometry. It utilizes microwaves to interrogate dielectric materials, including material with complex internal structure. The microwaves are reflected at areas of changing dielectric constant. The reflected energy and the interrogating beam are combined to form an interference pattern which is measured in the transceiver as a signal voltage. The method requires access to only one surface, does not require contact or a coupling medium. The signal voltage is sampled at many positions in the inspection area. This point cloud is displayed as an Evisive Scan™ image, which presents volumetric detail of the inspected part. This data is rich with information which is processed in near real time for advanced analysis. The technology has been successfully applied to Ceramic Matrix Composites where it is used to measure density and porosity and identify manufacturing defects. The technology has been demonstrated to be applicable to ceramic composite armor made of monolithic ceramic tiles in complex, multilayer, dielectric structures. The technology is being used to detect manufacturing defects in composite resin structures. The technology has been successfully demonstrated on fiber reinforced resin pipe overwraps, and the technology has been used for condition monitoring of reinforced rubber flexible couplings in nuclear power plants. The nuclear power plant application is performed under a fully qualified, US nuclear quality assurance 10CFR50 App B and NQA-1 compliant program. Examples of these applications are presented, with explanation of the operating principles of the technology and illustrations of the individual applications. Work included in the report is supported by the US Air Force Research Laboratory, US Army Tank-Automotive Research, Development and Engineering Center (TARDEC), US Army Research Laboratory and US Air Force Research Laboratory. Evisive would like to acknowledge project participation and support by Argonne National Laboratory, and Saudi Aramco.

In ASME 2004 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference. ASMEDC, 2004. http://dx.doi.org/10.1115/detc2004-57455.
Full textAbstract:
This paper presents an analysis tool and design method for MEMS parallel mechanisms. Due to processing constraints in MEMS fabrication, flexure joints are frequently used in MEMS mechanisms. Flexure joints offer advantages over other joint designs due to their monolithic characteristics. They can be used to reduce the size of manipulators or to increase the precision of motion. Their inherent flexibility, however, also results in task space compliance which needs to be carefully designed to match the task specification. This paper presents an analysis and design tool for such mechanisms by using the differential kinematics. Performance metrics are chosen based on manipulability and task stiffness matrices, which in turn are used in a multi-objective optimization. As an illustrative example, a 1-DOF MEMS parallel mechanism based on the macro- and meso-scale models designed by NIST is considered with several choices of performance metrics and design variables. The resulting designs are successfully fabricated using DRIE process.

Photonics on a silicon chip could enable a platform for monolithic integration of optics and microelectronics for applications of optical interconnects in which high data streams are required in a small footprint. In this talk I will review the challenges and achievement in the field of silicon photonics. Using highly confined photonic structures one can enhance the electro-optical and non-linearities properties of Silicon and enable ultra-compact and low power photonic components with very low loss. We have recently demonstrated several active components including GHz electro-optic low power switches and modulators, all-optical amplifiers and wavelength converters on silicon.

Full textAbstract:
In the field of MEMS, optical instruments and communication, the manipulation tasks such as mechanics property test of micro-material, micro-components assembling, and fibers connecting, are challenging for their minuteness and accuracy. It is measured in the scale of micrometer or sub micrometer. The full-compliant mechanisms are the best alternative, which are characteristically of their compliant hinge, and monolithic chip forming, and can be used for transmit a certain high-accuracy motion. Nevertheless, the full-compliant mechanisms have some shortages, for instance, small working space, nonlinear in large range motion, complicated in kinematical and mechanics etc. inherited from the parallel mechanisms that instructs the design of full-compliant mechanism generally. In this article, the redundant actuated parallel robot with full compliant is introduced to overcome some shortcomings of the full-compliant mechanism. The redundant actuated mechanisms provide redundant inputs and can be used in some complicated force manipulations, for example, improving the stress distribution while implements the main task for enhancing the fatigue nature of the complaint mechanism itself. As an example, a 3-DOF planar redundant actuated full-complaint robot is studied both in the modeling and control system.
