Abstract:
Recent work has reawakened interest in goal-directed or ‘model-based’ choice, where decisions are based on prospective evaluation of potential action outcomes. Concurrently, there has been growing attention to the role of hierarchy in decision-making and action control. We focus here on the intersection between these two areas of interest, considering the topic of hierarchical model-based control. To characterize this form of action control, we draw on the computational framework of hierarchical reinforcement learning, using this to interpret recent empirical findings. The resulting picture reveals how hierarchical model-based mechanisms might play a special and pivotal role in human decision-making, dramatically extending the scope and complexity of human behaviour.

Abstract:
Although extant research has studied incumbent resistance to digital platforms, it provides little understanding about when grassroots collective action by other ecosystem stakeholders against the digital platform is likely. In this paper, we identify the scope conditions detailing when local stakeholders can initiate grassroots collective action against the digital platform, a unique context characterized by fast growth, distributed innovation, role flexibility, and direct local connectivity, and propose viable solutions. Our conceptual framework suggests that grassroots collective action against the digital platform is most likely when the digital platform operates with localized scarce assets or localized precarious labor and when actors express their grievances through formalized channels. We combine business model design and stakeholder management perspectives to develop design-based solutions that involve a multisided business model structure, an inclusive stakeholder value proposition, and an ecosystem-centered governance. We call the combination of such design efforts relational business model design. To the incipient theory of digital platforms, we contribute a stakeholder-centered view of platform business models operating within local ecosystems, bridging research on collective action and stakeholder management with strategic management of platforms.

Abstract:
The article presents concepts and the Public Health Policy University of Lisbon Lab project to answer questions about the macro-environment of cancer and loneliness. Although the biomedical model has considered the disease’s general symptoms, it takes a holistic approach to incorporate several other circumstances that influence health. Emotional, social, psychological, and economic factors mirror influencing layers that affect wellness. Portugal follows Europe’s tendency and simultaneously reflects its reality. Governmental internal policies, amplified by regulations, improve disease prevention and treatment. Nevertheless, it focuses on the general population instead of on the individual. Once cancer, one of the leading causes of global death, is perceived as an isolated incident, we believe macro-environmental circumstances, and not only biological ones, must be considered. Furthermore, cancer in the elderly intensifies solicitude, and expanded policies and actions demand individual health determinants. In the Portuguese Public Health Policy, we started a collaborative Oncology, Human Kinetics, and Public Health Policy project. This is the first project of the Public Health Policy Lab from the Institute of Social and Political Sciences of the University of Lisbon. Based on a brief review of two research projects on improving cancer patients’ health, we promote micro-organisational projects to deal with the social phenomena of loneliness, physical activity, and lifestyle. As a sequence of the well-known social determinants, we endorse political determinants as the basis for public health. The latest worldwide governmental trend is to create public labs as an innovation of political policymaking. Throughout this reflection, the need for a new rational approach specially designed for a social model is considered.

Abstract:
In this paper, a pre-trained CNN model VGG16 with the SVM classifier is presented for the HAR task. The deep features are learned via the VGG16 pre-trained CNN model. The VGG 16 network is previously used for the image classification task. We used VGG16 for the signal classification of human activity, which is recorded by the accelerometer sensor of the mobile phone. The UniMiB dataset contains the 11771 samples of the daily life activity of humans. A Smartphone records these samples through the accelerometer sensor. The features are learned via the fifth max-pooling layer of the VGG16 CNN model and feed to the SVM classifier. The SVM classifier replaced the fully connected layer of the VGG16 model. The proposed VGG16-SVM model achieves effective and efficient results. The proposed method of VGG16-SVM is compared with the previously used schemes. The classification accuracy and F-Score are the evaluation parameters, and the proposed method provided 79.55% accuracy and 71.63% F-Score.

Abstract:
Regional governments and regional intergovernmental organizations play an increasingly important role in land use and transportation planning in many countries. In the U.S., regional organizations such as metropolitan planning organizations provide regional forums and institutions to coordinate actions of local government necessary to overcome collective action problems that result from the fragmentation of local authority. Their regional scope allows them to directly address collaboration problems or broker collaborative arrangements among local governments within their boundaries. Nevertheless, the scale of regional problems often extends beyond the boundaries of these regional entities. Thus, collaboration across regional governance organizations is necessary to address problems that have multi-regional impacts, such as large transportation projects. Extant research generally measures regional collaboration based on counts of collaboration actions undertaken, but this does not account for the fact that some are symbolic, while others require resources and commitment. Drawing insights from the institutional collective action framework, we advance an explanation for how regional organizations overcome collaboration risks to participate in collaborative solutions to regional and multi-regional problems. The analysis employs a unique national survey of metropolitan planning organizations (MPOs) and adds a novel application of item response theory (IRT) to capture differences in risk or difficulty among collaborative actions. The IRT results offer support for our ICA-based explanation of collaboration commitments. The implications of the findings for theory development and empirical study of RIGOs are discussed in conclusion.

Abstract:
Two kinds of the deficiencies exist in the traditional dam reliability and the safety coefficient calculation methods. First, it is impossible to give accurate mean to design variable in case study, because to large extent, means are greatly influenced by many objective factors or man-made effects, which degree of effects has greater degree of ambiguity. Second, the traditional reliability theory takes zero point as measure of dam’s failure or not, and on both sides of zero point the structure of state mutants from security to failure. But in fact, it’s very hard to give a definite limitation to the dam state from security to failure, because a fuzzy scope exists between stability and failure. On the basis of solving the above two issues, this paper for the first time applies fuzzy reliability theory to the stability research of tailings dam under earthquake action , considering fuzziness of both the event of tailings dam failure and the main variables and parameter. Integrating fuzziness and randomness, this paper explores fuzzy random reliability analysis methods of tailings dam engineering. The results of case study show that the calculation results agree well with the actual situation, this analysis method is more scientific and reasonable than traditional dam safety factor calculation method, and better reflects the real situation. It also provides a new way to calculate stability of tailing dam considering earthquake action.

Aiming at the complexity of rock discing mechanics, and the theory being not mature, the paper carried out three-dimensional numerical simulation for rock core discing based on strain soft model. The strain soft theory is introduced firstly, then numerically simulated how the depth of lug boss and original stress affect the rock core destroy pattern(discing if occurs, the thickness of disk), obtained the characters of rock core discing. Along with the drilling depth increases, the stress concentration scope below lug boss also increases, as well as the pressure stress concentration degree of side corner below of lug boss. Rock core discing can be induced respectively by shear action and tension action, sometimes it is combined by both of them. The destroy pattern of them especially destroy sequence are different. The strain soft numerical simulation could be used in original stress feedback analysis, has significant meaning.

Abstract:
Human action recognition has emerged as a challenging research domain for video understanding and analysis. Subsequently, extensive research has been conducted to achieve the improved performance for recognition of human actions. Human activity recognition has various real time applications, such as patient monitoring in which patients are being monitored among a group of normal people and then identified based on their abnormal activities. Our goal is to render a multi class abnormal action detection in individuals as well as in groups from video sequences to differentiate multiple abnormal human actions. In this paper, You Look only Once (YOLO) network is utilized as a backbone CNN model. For training the CNN model, we constructed a large dataset of patient videos by labeling each frame with a set of patient actions and the patient’s positions. We retrained the back-bone CNN model with 23,040 labeled images of patient’s actions for 32 epochs. Across each frame, the proposed model allocated a unique confidence score and action label for video sequences by finding the recurrent action label. The present study shows that the accuracy of abnormal action recognition is 96.8%. Our proposed approach differentiated abnormal actions with improved F1-Score of 89.2% which is higher than state-of-the-art techniques. The results indicate that the proposed framework can be beneficial to hospitals and elder care homes for patient monitoring.

Abstract:
Purpose Documents articulating public health nurses’ (PHNs’) roles, including Canadian standards and competencies, depict a broad focus working at multiple levels to improve population outcomes through the promotion of health equity. Conversely, Canadian experts depict a looming crisis, based on the rising disconnect between daily activities and ideal practice. While perfectly positioned, PHNs’ skills and abilities are under-utilized and largely invisible. The intention of this study was to develop a model to support the full scope of equity-focused PHN practice. Method A participatory action research approach was used. Qualitative data were gathered using semistructured interview guides during audio-recorded meetings. The data were coded into central themes using content analysis and constant comparison. A researcher reflexive journal and field notes were kept. A significant feature was full participant involvement. Results The outcome was a professional practice model to reframe the PHN role to focus on population health and equity. The model was imperative in promoting full scope of practice, dealing with workload pressures, and describing PHNs’ value within the organization and broader health system. Conclusion Professional practice models hold promise as frameworks to depict autonomous practice activities, situated within organizations and healthcare systems, and underpinned by nursing knowledge.

Abstract:
In the last decades there has been a growing interest in studying processes in improvement work. A particular interest has been the improvement process that the organisation undergoes and why events evolve in the way they do. By better understanding improvement processes and identifying supporting and hindering forces, the possibilities successfully to plan and implement improvement work in a systematic way increases. The focus of this thesis is organisation processes in schools and the relations that hold between planned and emergent improvement, when using a research-based strategy. The aim of the study is to describe and understand how processes are initiated, developed and completed when using a strategy called ‘Scope for Action Model’(frirumsstrategin). The empirical material of the study was organised and analysed according to Van de Ven’s and Poole’s four ideal types for process studies. Within each type, motors have been identified, which contain generative mechanisms that are a key to how actions, events and activities emerge and are driven forward. The results of the study show that the emergent initiatives are more frequent than the planned ones and that they are more likely to generate an improvement – in the study defined as something new in the organisation. However, on several occasions the planned improvement work inspires emergent initiatives for improvement and in some cases seems to be a fundamental condition for their existence. The different motors, which in the analysis are seen as driving forces, support or challenge each other, making the process develop and produce a result. The study shows that the participants reshape the strategy to make it fit into the organisation of the school. The results also show that teachers and principals have to be well-informed of how to work with a strategy in a practical and constructive way. They have to be able to translate crucial moments in the strategy to stimulate the participants to creative actions. The strategy for school improvement is not shown to be a solution which itself can create improvement, but in combination with the participant’s creative goal settings it can be a contributory factor.
Denna avhandling riktar intresset mot skolförbättring och de processer som uppstår när en planerad förändring genomförs på skolor med stöd av en forskningsbaserad strategi. Syftet med avhandlingen är att beskriva och förstå hur dessa processer - i arbetet med frirumsstrategin - initieras, fortlöper och avslutas. Studien visar att det finns relationer mellan planerade och framväxande processer. De framväxande processerna är mest frekventa och har sin grund i deltagarnas egna målformuleringar. De förmår skapa utveckling i skolverksamheterna, något de planerade processerna inte lyckas med. Det planerade förbättringsarbetet tycks bidra genom att vara en inspirationskälla eller i vissa fall en förutsättning för de framväxande initiativ som tas av deltagare från olika delar av organisationen. Studien pekar på att en strategi kan vara igångsättare av förbättringsarbete och utgöra en grund för skolor att utgå från. Av resultatet framgår att det är viktigt att rektorer och lärare har goda kunskaper om förbättringsarbetets processer för att kunna använda strategin på ett konstruktivt sätt. Genom att ha insikt i vilka mekanismer som påverkar processer kan ett förbättringsarbete ledas medvetet samt tillåtas innehålla både de konflikter och den samstämmighet som kan bidra till att utveckling sker.

Abstract:
This thesis traces the immigration of "model minority" mothers: Chinese, Japanese, and Korean, from their home countries to the United States. It examines the reasons women immigrate to the United States, the situations into which they immigrate, and the ways that they adapt traditional East Asian modes of mothering and child rearing techniques to life in the United States. This thesis finds that Chinese, Japanese, and Korean women emigrate to the United States primarily under the direction of male figures of authority. Motivators of their emigration include leaving poverty and war in their own countries, joining husbands or potential husbands in the United States, hoping to escape the cultural restrictions of their home countries, or becoming prostitutes. As these women make their own way in the United States, they find themselves encountering immense cultural difficulties, not the least of which is the alteration of their role as mothers as they try to raise their children in an entirely new cultural context. Despite the hopes of many of these women, what they find in the United States is not a life of leisure and wealth; rather, they are forced into positions in which they must work for long hours outside the home to provide economically for their families as well as raise their children and care for the home. This thesis finds that memoirs, novels, biographies, autobiographies, narratives, historical accounts, and sociological data highlight several major areas of adaptation for these women including: the differences in these women's sense of community in America, their expectations of the educational system in the United States, the reversal of power in the use of language between mother and daughter, and the complex measures of adaptation to and rejection of U.S. cultural norms that mothers must implement while raising their children. Rather than being crushed by the labor that they must perform and the cultural adaptations that they must make, these women willingly sacrifice their lives to build a base upon which their children can succeed through the attainment of higher education leading toward upward mobility.

Abstract:
It is widely believed that the sperm-specific protein phospholipase C zeta (PLCζ) is released into the oocyte upon fusion and initiates calcium (Ca2+) oscillations which regulate oocyte activation. Reduced amounts, abnormal localisation patterns, and aberrant forms of PLCζ underlie certain types of male-factor infertility, prompting significant interest in the use of this fundamental protein as a clinical therapeutic agent or diagnostic marker. This thesis systematically addressed a range of outstanding questions relating to the expression, localisation, and therapeutic/diagnostic application of PLCζ. Using immunohistochemical and quantitative immunofluorescence techniques, the current study investigated the effect of paternal age and epididymal maturation upon PLCζ expression and localisation in mouse sperm. Neither age nor epididymal maturity exhibited significant effect upon the total level of PLCζ in mouse sperm, although there was a significant trend towards post-acrosomal localisation as sperm matured during transit in the epididymis. Immunohistochemical analysis of mouse testis showed that the expression of PLCζ first appeared at the roundspermatid stage of spermatogenesis. Paternal age did not influence total levels of PLCζ expression or localisation pattern in human sperm samples (n=29), with PLCζ being predominantly localised to the post-acrosomal region. A significant reduction (34%) was detected in the proportion of sperm exhibiting PLCζ from an oocyte-activation deficient patient compared with fertile controls. Novel immunohistochemical analyses suggested, for the first time, that PLCζ is first expressed from the round spermatid stage in humans, and that the analysis of PLCζ expression in human testicular biopsies (n=29) may provide credible indication of the oocyte activation ability of surgically-retrieved sperm samples from infertile patients. Initial data also suggest that flow cytometry may serve as a useful prognostic/diagnostic tool for the quantitative analyses of PLCζ expression in human sperm samples. Mammalian and bacterial expression systems were utilised to generate recombinant human PLCζ protein as a therapeutic agent and for the generation of a novel monoclonal anti-PLCζ antibody respectively. Expression studies using HEK293T cells demonstrated that human PLCζ appeared to localise to the endoplasmic reticulum and that the EF hand domain appeared to be involved in regulating this pattern of localisation. Collectively, these studies extend our fundamental knowledge of how PLCζ is expressed in developing sperm and assist in the translation of PLCζ as a clinical therapeutic and diagnostic biomarker for oocyte activation ability.

Abstract:
While some attempts have been made to model the behaviour of the grand piano action (the mechanism that translates a key press into a hammer striking a string), most researchers have reduced the system to a simple model with little relation to the components of a real action. While such models are useful for certain applications, they are not appropriate as design tools for piano makers, since the model parameters have little physical meaning and must be calibrated from the behaviour of a real action. A new model for a piano action is proposed in this thesis. The model treats each of the five main action components (key, whippen, jack, repetition lever, and hammer) as a rigid body. The action model also incorporates a contact model to determine the normal and friction forces at 13 locations between each of the contacting bodies. All parameters in the model are directly measured from the physical properties of individual action components, allowing the model to be used as a prototyping tool for actions that have not yet been built. To test whether the model can accurately predict the behaviour of a piano action, an experimental apparatus was built. Based around a keyboard from a Boston grand piano, the apparatus uses an electric motor to actuate the key, a load cell to measure applied force, and optical encoders and a high speed video camera to measure the positions of the bodies. The apparatus was found to produce highly repeatable, reliable measurements of the action. The behaviour of the action model was compared to the measurements from the experimental apparatus for several types of key blows from a pianist. A qualitative comparison showed that the model could very accurately reproduce the behaviour of a real action for high force blows. When the forces were lower, the behaviour of the action model was still reasonable, but some discrepancy from the experimental results could be seen. In order to reduce the discrepancy, it was recommended that certain improvements could be made to the action model. Rigid bodies, most importantly the key and hammer, should be replaced with flexible bodies. The normal contact model should be modified to account for the speed-independent behaviour of felt compression. Felt bushings that are modelled as perfect revolute joints should instead be modelled as flexible contact surfaces.

Aquesta tesi presenta una serie de tecniques per resoldre el problema del reconeixement de les accions humanes en video. El nostre primer enfocament cap a aquesta tema es basa en la optimitzacio d'un model probabilistic de les parts del cos utilitzant una Hidden Markov Model (HMM). Aquest enfocament es basa en un strong model, capac de distingir entre accions similars considerant nomes les parts del cos que tenen les majors aportacions en la realitzacio de certes accions, per exemple en cames per caminar i correr, o en bracos per a accions com boxa i aplaudir. El nostre seguent enfocament es basa en l'observacio de que el reconeixement d'accions es pot realitzar usant nomes informacio visual, ii la postura humana desenvolupada durant una accio, analitzant la la informacio d'uns quants frames en lloc d'examinar la sequencia completa. En aquest metode, les accions es representen mitjançant un model Bag-of-key-poses per poder capturar la variacio de la postura humana durant el desenvolupament d'una accio. Per fer front al problema del reconeixement de l'accio en escenes complexes, tot seguit es proposa una aproximacio model free basada en l'analisi de punts d'interes espai-temporals (STIPs) que disposen de molta informacio local.

Nuestro siguiente enfoque se basa en la observacion de que el reconocimiento de acciones se puede realizar usando solo informacion visual, i.e. la postura humana desarrollada durante una accion, analizando la la informacion de unos cuantos frames en lugar de examinar la secuencia completa. En este metodo, las acciones se representan mediante un modelo Bag-of-\textit{key-poses} para poder capturar la variaci\'{o}n de la postura humana durante el desarrollo de una accion.

Los resultados obtenidos demuestran que hemos mejorado la precision en la deteccion de acciones humanas en video.
Automatic understanding of human activity and action is a very important and challenging research area of Computer Vision with wide scale applications in video surveillance, motion analysis, virtual reality interfaces, robot navigation and recognition, video indexing, content based video retrieval, HCI, health care, choreography and sports video analysis etc. This thesis presents a series of techniques to solve the problem of human action recognition in video. First approach towards this goal is based on the a probabilistic optimization model of body parts using hidden markov model (HMM). This strong model based approach is able to distinguish between similar actions by only considering the body parts having major contributions to the actions, for example legs for walking and jogging; arms for boxing and clapping. Next approach is based on the observation that the action recognition can be done using only the visual cue, i.e. human pose during the action, even with the information of few frames instead of examining the whole sequence. In this method, actions are represented by a Bag-of-key-poses model to capture the human pose variation during an action. To tackle the problem of recognizing the action in complex scenes, we propose a model free approach which is based on the Spatio-temporal interest point (STIP) and local feature. To this end, a novel STIP detector is proposed which uses a mechanism similar to that of the non-classical receptive field inhibition that is exhibited by most orientation selective neurons in the primary visual cortex. An extension of the selective STIP based action recognition is applied to the human action recognition in multi-camera system. In this case, selective STIPs from each camera view point are combined using the 3D reconstructed data, to form 4D STIPs [3D space + time] for multi-view action recognition. The concluding part of the thesis dedicates to the continuous visual event recognition (CVER) on large scale video dataset. This is an extremely challenging problem due to high scalability, diverse real environment state and wide scene variability. To address these issues, a motion region extraction technique is applied as a preprocessing step. A max-margin generalized Hough Transform framework is used to learn the feature vote distribution around the activity center to obtain an activity hypothesis which is verified by a Bag-of-words + SVM action recognition system. We validate our proposed approaches on several benchmark action recognition datasets as well as small scale and large scale activity recognition datasets. We obtain state-of-the results which shows a progressive improvement of our proposed techniques to solve human action and activity recognition in video.

Abstract:
Design changes can be surprisingly complex. We examine the problems they cause and discuss the problems involved in predicting how changes propagate, based on empirical studies. To assist this analysis we distinguish between (a) a static background of connectivities (b) descriptions of designs, processes, resources and requirements and (c) the dynamics of design tasks acting on descriptions. The background might consist of existing designs and subsystems, or established processes used to create them. The predictability of design change is examined in terms of this model, especially the types and scope of uncertainties and where complexities arise. An industrial example of change propagation is presented in terms of the background (connectivity) - description - action model.

Full text
Abstract:
This paper provides a case history of a highly successful approach that was developed and implemented for the U.S. Department of Energy (DOE) for the cleanup and remediation of a large and diverse population of uranium mill tailings sites located in the Western United States. The paper addresses the key management challenges and lessons learned from the largest DOE Environmental Management Clean-up Project (in terms of number of individual clean-up sites) undertaken in the United States. From 1986 to 1996, the Department of Energy’s Grand Junction Projects Office (GJPO) completed approximately 4600 individual remedial action site cleanup projects for large- and small-scale properties, and sites contaminated with residual hazardous and radioactive materials from former uranium mining and milling activities. These projects, with a total value of $597 million, involved site characterization, remedial design, waste removal, cleanup verification, transportation, and disposal of nearly 2.7 million cubic yards of low-level and mixed low-level waste. The project scope included remedial action at 4,200 sites in Grand Junction, Colorado, and Edgemont, South Dakota; 412 sites in Monticello, Utah; and, 44 sites in Denver, Colorado. The projects ranged in size and complexity from the multi-year Monticello Millsite Remedial Action Project, which involved investigations, characterization, remedial design, and remedial action at this uranium millsite along with design of a 2.5 million cubic yard disposal cell, to the remediation and reconstruction of thousands of smaller commercial and residential properties throughout the Southwestern United States. Because these projects involved remedial action at a variety of commercial facilities, businesses, churches, schools and personal residences, and the transportation of the waste through towns and communities, an extensive public involvement program was the cornerstone of an effort to promote stakeholder understanding and acceptance. The Project established a DOE model for rapid, economical, and effective remedial action. During the ten years of the contract, the management operations contractor (Duratek) met all project milestones on schedule and under budget, with no cost growth from the original scope. By streamlining remediation schedules and techniques, ensuring effective stakeholder communications, and transferring lessons learned from one project to the next, the contractor achieved maximum efficiency and the lowest remediation costs of any similar DOE environmental programs at the time.

Full text
Abstract:
Prediction of the vibratory and acoustical behavior of gearboxes is generally based on characterization of the excitation sources, overall modeling of the gearbox, modal analysis and solving of the parametric equations of motion generated by these models. On the building process of such large degrees of freedom models, the elastic coupling induced by the gear mesh is generally described by the parametric meshing stiffness k(t) along the line of action. This kind of model is not able to take into account the load distribution along the tooth face width, even though the resulting moment can constrain rotational angles associated to wheels tilting and flexural deformation of shafts. The scope of this study is to introduce the coupling terms between wheels associated to these phenomena. Some examples show how they can influence the gear modal characteristics and dynamic response and, consequently, the vibratory and acoustical response of the gearbox.

Abstract:
Increasingly the dominance of engineering process in yacht design development imposes limitations on the possibilities and scope for creative design. Designers are also limited to some extent by tradition - following what has gone before - as well as being hampered by class and rating rules. This paper explores an alternative methodological framework for yacht design that has innovation as its central concern. This method has been trialled and developed in the design of the Shaw sport boats and performance keel yachts. It gives due weight to the iterative process, utilising an action research model which affords access to the heuristics of iteration.

Abstract:
This paper presents a novel indirect matching approach between the function layer and the form layer to enhance the capability for the FBS method to obtain the creative conceptual design results. Firstly, the basic operation actions set, which is composed of the basic operation actions obtained by decomposing each function in the lowest level of the function decomposition tree in the FBS model into the sub-functions, in the function layer is regrouped dynamically. This behavior regroup process has introduced the new design variables into the conceptual design process and leads the behavior creativity to produce. On the other hand, considering the multi-functions for each basic structure to have and representing these functions with the basic operation actions, then the basic operation actions set in the form layer is set up. Dynamic regrouping this set in the form layer, the new design variables has been introduced into the conceptual design process, and leads the form creativity to produce. Through the above behavior-form double directions creative process, the solution scope of the conceptual design is enlarged obviously. Therefore, the method present in this paper has enough capability to obtain the creative conceptual results. Furthermore, the model presented in this paper is represented with the quotient space mathematically. The case study has shown that in the function layer, through adjusting the attribute function, which determines the partition grain of the basic operation actions set in the function layer or in the form layer, the new behaviors can be generated.

Abstract:
The paper deals with the so-called aspectual triplets of the Russian verb. Based on the data from the Russian National Corpus, it proposes a diachronic method to study triplets as well as a two-component model of the Russian aspect as an alternative to the traditional word-based classification model. The first component of the model is a morphological mechanism of the imperfectivizing suffixation of prefixed verbs that is inflectional (ras-kry-t’PFV — ras-kryva-t’IPFV2 ‘disclose, reveal’), but has a limited scope of action (prefixed verbs only). The second component of the model is the actionality (lexical aspect) with a maximal scope. Related to the verb class as a whole, it is especially crucial for non-prefixed simplexes. Actionality enables the functioning and perfective / imperfective characterization of simplexes which do not fall under the inflectional grammatical aspect. The analysis of ten biimperfective triplets resulted in several observations and conclusions. One of them concerns the role of a ‘joker’, which all imperfective simplexes (IPFV1) have in the aspectual triplets as (quasi)synonyms for corresponding secondary imperfectives (IPFV2). A working hypothesis on the predominance of IPFV1 over PFV in every triplet, based on the broader polysemy of the former, has not been confirmed. However, the two-component model has explanatory power for the cases of reverse frequency (PFV over IPFV1) through its lexical aspect component. Another working hypothesis on a possible increase or a decrease in the number of secondary imperfectives in diachrony was partially confirmed — an increase was noted for the 20/21st century.

Abstract:
The contribution presents the faculty development program of the University of Milano-Bicocca, called “Teaching large classes”. The objective of this paper is to illustrate the training structure of this project (launched in 2016 with a series of pilot actions that became fully operational the following year) and its recent developments. The paper intends to provide a detailed description of the three main principle that shape the structure of the training program: the continuum of immersion and distancing in training methodologies; the isomorphism between learning contents and teaching methodologies; the focus on the didactic transposition and education reconstruction process. The analysis of these principles shows that the inter- and trans-disciplinary approach of the training program is a crucial condition to the interconnectedness of the three principles in a consistent training structure. Furthermore, the multi- inter- and transdisciplinary approach allows for the development of the project with a broader scope.

Abstract:
The performance of heat exchangers degrades with time due to fouling or deposition of material on the heat transfer surface. The fouling of critical exchangers in manufacturing plants results in a significant cost impact in terms of production losses, energy efficiency, and maintenance costs. While most plants monitor their exchangers to some degree, the ability to effect real and sustainable improvements requires four components: (1) real time monitoring; (2) an advance warning mechanism; (3) the ability to diagnose the cause of fouling; and (4) the ability to treat the cause in order to slow or reverse the degradation. CHeX is a comprehensive tool which monitors, predicts, and diagnoses heat exchanger performance. The unique features of this advanced technology include: numerous data cleaning steps to improve data quality and isolate a net fouling trend, an adaptive model which learns from the past to predict performance three years in advance, and knowledge-based diagnostics which identify the probable cause(s) of fouling and recommend corrective actions. The final control action is performed by a field engineer in adjusting the fouling treatment. The scope of the current paper includes only the detection and prediction features. To date, CHeX has been validated at three chemical processing plants, for fourteen exchangers. Selected case studies shall be presented to demonstrate the power of its algorithms over traditional calculations.

Abstract:
Morphing winglets are innovative aircraft devices capable to adaptively enhance aircraft lift distribution throughout the flight mission while providing augmented roll and yaw control capability. Within the scope of the Clean Sky 2 REG IADP, this paper deals with nonlinear simulations of a regional aircraft wing equipped with active morphing winglets in manoeuvring conditions. The fault tolerant morphing winglet architecture is based on two independent and asynchronous control surfaces with variable camber and differential settings capability. The mechanical system is designed to face different flight static and dynamic situations by a proper action on the movable control tabs. The potential for reducing wing and winglet loads by means of the winglet control surfaces is numerically assessed by means of static aeroelastic analyses, using a feedforward manoeuvre load alleviation controller. An electro-mechanical Matlab/Simulink model of the actuation architecture is used as design tool to preliminary evaluate the complete system performance and the ability to cope with the expected morphing aeroshapes. Then, the aeroelastic model of the aircraft is combined with the nonlinear simulator of the response of the winglet actuation system to evaluate a symmetric and asymmetric manoeuvres obtained by a sudden deflection of the main control surfaces. The use of the morphing winglet tabs shows to alleviate the wing loads in such conditions. The introduction of the dynamic actuator model leads to a reduction of the performances with respect to predictions of the static analyses but a reduction of the manoeuvre loads can still be observed.

Abstract:
The GustoMSC Tri-Floater is a slender and robust three-column semi-submersible supporting an offshore wind turbine. Model tests were performed for a Tri-Floater equipped with an operational wind turbine and mooring system exposed to wind and waves in the offshore basin at MARIN. A high quality wind setup and special low Reynolds number blades were used, aiming at delivering the Froude scaled thrust. The base scope of experiments was performed with fixed blade pitch angle and generator speed. Some of the experiments were repeated with active blade pitch and generator torque control using a dedicated algorithm developed by ECN. The experiments covered typical operational and survival design conditions. Numerical simulations for the same wave and wind conditions were performed using ANSYS-AQWA coupled with PHATAS. The paper describes the setup and results of both the model tests and the simulations. From the comparison of the numerical and experimental results, it is concluded that coupled aero-hydro-servo-elastic simulations can be used to predict the response of the floating offshore wind turbine to a sufficiently accurate level for design purposes. Furthermore, it is shown that the Tri-Floater motion response is very favorable and that the nacelle accelerations, air gap and mooring loads comply with the design requirements.
