Full textAbstract:
In this article I attempt to trace the genealogy of the body-technology relation in the 20th century as it emerges at two specific historical junctures: (i) The Taylorist/Fordist ergonomic society of the early part of the 20th century. To this end it outlines a double trajectory: firstly the shift in the epistemology of monstrosity from pre-enlightenment singularity to enlightenment replicability, and thus the possibility of containment and ‘technological monstrosity’ in the modern era; and secondly the emergence of Fordism as a social and scientific system which is premised on the body-as-machine but is underpinned by the fascination presented by the possibility of ‘machine pathology’, (ii) The emergence of the ‘statistical person’ in the late 20th century; a species of more or less psychopathological identity related to the predominance of information processing in contemporary urban epistemology. I argue that the late 20th century relation to technology, the cybernetic or statistical, is the inverse of that of the Fordist worker at the assembly line in the early part of the century, the era of the ‘sexualized machine’.

Full textAbstract:
Sex robots are a controversial topic. Understood as artificial-intelligence enhanced humanoid robots designed for use in partnered and solo sex, sex robots offer ample opportunities for theorizing from a Human-Machine Communication (HMC) perspective. This comparative literature review conjoins the seemingly disconnected literatures of HMC and sexuality studies (SeS) to explore questions surrounding intimacy, love, desire, sex, and sexuality among humans and machines. In particular, I argue for understanding human-machine sexualities as communicative sexuotechnical-assemblages, extending previous efforts in both HMC and SeS for more-than-human, ecological, and more fluid approaches to humans and machines, as well as to sex and sexuality. This essay continues and expands the critical turn in HMC by engaging in an interdisciplinary exercise with theoretical, design, and use/effect implications in the context of sex robots.

With recent introduction of poker machines in Australia, there have been claims of increases in the number of women with gambling-related problems. Research in the United States indicates, however, that men have a higher incidence of pathological gambling. The aims of this study were to ascertain among game machine users in a major city in Australia whether (a) more women than men exhibited symptoms of pathological gambling, (b) women reported higher guilt associated with their gambling, and (c) gamblers' self-assessment on several mood states was predictive of pathological gambling. A modified version of the South Oaks Gambling Screen was administered to 104 users of game machines (44 men, 60 women) sampled from patrons at gaming venues in Melbourne, Australia. Data indicated no significant sex difference in the proportion of pathological gamblers or in gambling-related guilt. Self-assessment of Happiness, Propensity for Boredom, and Loneliness, significantly predicted scores on the South Oaks Gambling Screen, with Unhappiness a significant independent predictor of pathological gambling. This may suggest that gambling acts to fill a need in the lives of unhappy people or that individuals who lack control over their gambling report higher unhappiness. Further research is needed to discover this relationship.

In Sex Robots: Love in the Age of Machines (2022), Maurizio Balistreri tackles the provocative topic of sex robots. Through engaging with the most common questions and concerns that arise in discussions about sex robots, Balistreri provides a good overview and introduction to current debates while, at the same time, bringing their own opinion to the fore. Given that a decent array of topics are covered in just over 100 pages, the book doesn’t necessarily go into great philosophical detail and analysis. However, this serves well for those who are not as familiar with the topic at hand.

Full textAbstract:
Pre-slaughter ultrasound and carcass measurements of ribeye area (REA) and backfat (FAT) were recorded on composite beef bulls (n = 60), heifers (n = 60) and steers (n = 60). Breed composition of the composite was: 0.44 British (Hereford, Angus and Shorthorn) 0.25 Charolais, 0.25 Simmental and 0.06 Limousin. The Aloka SSD-1100 (AL) and the Tokyo Keiki CS 3000 (TK) ultrasound machines were compared by evaluating the difference between ultrasound and carcass measurements (bias), and the standard error of prediction (SEP). AL under-predicted REA in all three sexes while TK overpredicted heifers and steers and underpredicted bulls. Both machines were similar in accuracy among bulls for REA. For FAT AL underpredicted all three sexes while TK underpredicted heifers and had very small bias for bulls and steers. SEP for FAT were similar for both machines. Both machines underpredicted REA in larger muscled cattle and overpredicted in smaller-muscled cattle. Both machines also underpredicted FAT in fatter animals and overpredicted FAT in leaner animals. Machines were similar in accuracy among cattle with larger REA but differed significantly (P < 0.05) among smaller-muscled cattle. Machines were comparable in accuracy among animals of all FAT sizes. This study demonstrates that there is an important relationship between machine and the size and depth of muscle and backfat, respectively, and consequently between machine and sex, in accuracy of ultrasound prediction. Key words: Beef cattle, ultrasound, accuracy, back fat, ribeye area

Full textAbstract:
Bluetooth-operated sex toys penetrate and are penetrated by the human body, leaving code behind. This article analyzes the relationships that develop between bodies and Bluetooth-operated interactive sex toys. Resembling the pods and portals of David Cronenberg’s film eXistenZ, interactive sex toys allow us to consider how technologies relate intimately to the sexual body. I use Massumi’s work on virtuality and affect theory as a starting point from which to frame embodiment, virtuality, and the circulation of affects. Further, I consider the importance of embodiment and the translations of intensities and vibrations through digital coding among the open sexual body, the technology of the sexual machine, and the applications that foster those connections, in the context of Bluetooth-operated sex toys. This article advocates the need to consider intimate encounters between interactive sex toys and bodies as complex technological and biological assemblages, where vibrating machines and the human body’s flesh come into intimate connection through datafication.

Full textAbstract:
This study examines the evolution of posthumans in novels and movies as a relationship between sex and love, focusing on Giorgio Agamben's Homo Sacer. Agamben tried to reveal the essence of life politics through the concept of Homo Sacer, which is, bare life. Bare life means only biological life in all living things that Aristotle divided into Zoe and Bios, and humans pursue the life of Bios, who live as a member of a community of society, politics, and culture beyond the life of Zoe. Artificial intelligence robots have only Zoe's life, deprived of their social and political life, Bios. With the development of technology, such AI has a more human appearance, emotion, intelligence, and ability than humans, and dreams of the realm of Bios pursued by humans. I analyzed the emotions and identity of humans and posthuman beings in the AI era, focusing on Rachel in Phillip Dick's novel, the movie Ex Machina's Ava, and David Mitchell's novel of the same name, Cloud Atlas' Sonmi-451. Female mechanical humans are creatures that have life but have no value for existence, and they become invisible others in oppression and governance, appearing as unfamiliar fears, that is, the uncanny. This study examined why humans pursue sexual relationships with machine humans through female AI's uncanny, whether it is possible to fall in love with them, and what it means for programmed AI to evolve on its own, control emotions, and use it to mock humans. As machines become more human-like, their uncanniness makes humans even more uneasy and fearful. If humans can no longer be distinguished from machines, it is necessary to redefine humanity to understand what makes us human. Only then, when the science fiction imagined becomes a scientific reality, can we truly live as humans.

Full textAbstract:
Jane Austen’s final novel fragment Sanditon has inspired continuations of many kinds from the mid-nineteenth century onwards. The most recent literary afterlife it has generated is the 2019 British adaptation for ITV, created by Andrew Davies, and with a screenplay by Davies, Justin Young and Andrea Gibb. This eight-part adaptation attempts to recreate Austen’s Regency world but reimagines and develops Sanditon through the lens of twenty-first century sexual sensibilities. Most notably, depictions of male nudity and sex acts demonstrate the adaptation’s engagement with contemporary sexual politics. Scenes offering salacious views of naked men sea-bathing counter the historical tradition of the female nude offered up for male gaze; the female body, in contrast, remains fully clothed in response to the contemporary Me-Too context. Furthermore, the inclusion of sex scenes, a character with a backstory of sexual abuse, a relationship featuring coercive control, and an ending denying the heroine her man reflects the zeitgeist. However, the disappointing British viewing figures for Sanditon suggest that sex does not always sell, particularly when it comes to creating a successful twenty-first century Austen adaptation.

Full textAbstract:
“Heterosex” occupies a contradictory position in academic feminism. While much research has been done through the decades, the substantive research focus, and the theoretical approaches used to conceptualise and explain it, have remained more limited. This has produced significant empirical gaps and limitations, and while feminists have remarked on this for some time (Albury, 2008, Segal, 1994), it has not been seriously addressed. The diversity of knowledge production has continued to remain “strangely repressed” (Smart, 1996). This thesis represents an intervention in relation to this landscape. Firstly, it identifies and traces the methodological and theoretical limitations within the contemporary and historical body of work on heterosex, and through this develops an alternative conceptual framework and analytical ground, offering the possibility to render it more expansively. Secondly, through the accounts of 27 middle and working-class heterosexual men and women, it theorises heterosex and provides insight into its experience clustered along four areas. These areas are informed by theoretical work on phenomenology, intersubjectivity and ethics, and strongly account for experiential aspects of heterosex. The research findings highlight the significance of practice and learning in determining how heterosex is experienced: participants asynchronously develop capacities, knowledges and skills that are indivisibly connected to the experiential over time. This then also constitutes subjectivity as sedimented through time, yet, as able to change. Rather than gender or class providing the primary explanatory ground for the experience of heterosex, age (youth) and in/experience figure as the most salient variables in how participants’ make sense of heterosex at any given point in time. Crucially also, women and men’s experiences of heterosex often challenge the portrayal offered by much of the feminist/queer literature on heterosex. The thesis thus urges for further interrogation of the limits of focus/approach for supposed “proper” political/ethical feminist research on heterosex, and for a proliferation of knowledges on this research object. It concludes that heterosex cannot be adequately captured through categories of gender or normativity alone - as commonly foundational to much feminist and queer work - and that feminist “disciplinarity” (Wiegman, 2012) enacts limitations on the possibilities for knowledge production on heterosex today.

Full textAbstract:
From the simple electronic vibrator to the complex assemblages of cybersex, sex and technology have always intersected. The dynamic relations between sexuality and technology are constantly changing along with the ways in which human beings achieve psychological and bodily pleasure through these devices. Sex machine, a term that denotes an automated device that can assist human in the pursuits of sex, has been broadly defined as therapeutic and pleasure machines in the West. Large numbers of sex machines have been documented in Europe and America starting from the nineteenth century, and were widely produced and utilized by medical practitioners, sex toy makers and individuals throughout history. This research focuses on three kinds of sex machines that have been produced and represented visually in recent years: fucking-machines, teledildonics and humanoid sex machines. By using the poststructuralist approach of combining the material and symbolic dimensions in the analysis, the thesis aims at investigating the cultural significance of sex machines by studying how they are identified, represented and produced as cultural text/artefact in the Euro-American subcultural sexual context. Through a queer reading of sex machines, the project will explore how sex machines re-configure the way we understand body, gender, sexuality and technology in the human pursuit of pleasure and desire.

Le problème principal consiste à choisir un modèle et à en identifier les paramètres pour traduire au mieux les comportements de la machine durant les différents régimes de fonctionnement. Compte tenu du comportement non linéaire des matériaux magnétiques les méthodes classiques ne donnent pas de résultats satisfaisants et particulièrement en régime dynamique. Une amélioration de ces tests est obtenue grâce à l'exploitation des régimes transitoires. Une attention particulière est accordée à la constante de temps rotorique qui occupe une place importante lors du contrôle des machines. Nous proposons un essai en transitoire qui permet de l'obtenir avec une bonne précision. La détermination des paramètres mécaniques faites séparément

Full textAbstract:
La pratique artistique de Piotr Kowalski (1927-2004) est singulière. Mathématicien, scientifique puis architecte, Piotr Kowalski s’oriente dès les années soixante vers la sculpture et créé des outils d’art qui matérialisent des lois physiques ou de pensée. Ses « machines à faire des vierges » agissent sur le spectateur comme principe cognitif en proposant d’expérimenter directement une connaissance. La démarche de Piotr Kowalski rompt avec l’idée romantique de l’artiste isolé dans son atelier. Convaincu que la sculpture doit produire avec les moyens contemporains, il travaille dans les usines et les laboratoires où il met au point des procédés innovants. Cette attitude réconcilie l’art, la science et la technique. La carrière de Piotr Kowalski est emblématique de quarante années de création et de bouleversements institutionnels. Exposés dans les établissements les plus prestigieux (la Kunsthalle de Berne, le Musée Guggenheim, le Stedelijk Museem, le Moderna Musset, le Musée national d’Art moderne), Piotr Kowalski participe en parallèle aux grandes transformations du paysage artistique français (Beaubourg, la Cité des sciences et de l’industrie, la Défense, les villes nouvelles). À travers un parcours chronologique thématisé, cette monographie critique tend à rétablir l’importance d’une œuvre trop souvent réduite à la thématique art et science ou pire à de l’art technologique. La thèse présente le premier catalogue raisonné comprenant les projets d’œuvres non réaliséesPiotr Kowalski’s (1927-2004) artistic approach is a distinctive body of work. Mathematician, scientist and then architect, Piotr Kowalski focuses from the 60s on sculpture and creates “art tools” materializing laws of physics or ways of thinking. His “virgins maker machines” influence the cognitive part of the viewers by directly experimenting a knowledge. Piotr Kowalski’s approach breaks with the romantic idea of the lonely isolated artist in his workshop. Convinced that sculpture must be made with contemporary means, he works in factories and laboratories, where he implements innovative processes.This attitude enable to bring together art, science and technical knowledge. Piotr Kowalski’s career is the symbol of fourty years of creation and institutional changes. Exhibited in the most prestigious institutions (Kunsthalle in Bern, Guggenheim Museum, Stedelijk Museem, Moderna Musset, Musée National d’Art Moderne), Piotr Kowalski also takes part in the great changes of the French art landscape (Beaubourg, la Cité des sciences et de l’industrie, la Défense, les villes nouvelles). Through a themed timeline experience, this critical monograph tends to restore the importance of his work, often reduced to themed art and sciences, or even worth to technological art. The thesis presents the first catalogue raisonné including his non finalized work projects

Ce travail porte sur la modélisation, la simulation, la commande du système cycloconvertisseur-machine synchrone et asynchrone et de la comparaison de leurs performances en terme d'ondulation de couple électromagnétique. On montre que la machine synchrone permet, en statique, d'avoir un couple moins ondulé. Par contre, la machine asynchrone présente un meilleur comportement dynamique lors du démarrage. Afin de limiter les harmoniques provoqués par le temps mort de sécurité, une deuxième horloge permettant d'imposer la durée du palier nul à une valeur fixe est proposée. Enfin, dans le but de réduire les ondulations du couple, une modification de la structure du cycloconvertisseur en ajoutant six thyristors de roue libre est étudiée. Cette modification a permis de réduire, d'une façon importante, les ondulations du couple de la machine synchrone fonctionnant à facteur de puissance unitaire

Full textAbstract:
The thesis falls into the field of machine olfaction and accompanying experimental set up for chemical gas sensing. Perhaps more than any other sensory modality, chemical sensing faces with major technical and conceptual challenges: low specificity, slow response time, long term instability, power consumption, portability, coding capacity and robustness.
There is an important trend of the last decade pushing artificial olfaction to mimic the biological olfaction system of insects and mammalians. The designers of machine olfaction devices take inspiration from the biological olfactory system, because animals effortlessly accomplish some of the unsolved problems in machine olfaction. In a remarkable example of an olfactory guided behavior, male moths navigate over large distances in order to locate calling females by detecting pheromone signals both rapidly and robustly.
The biomimetic chemical sensing aims to identify the key blocks in the olfactory pathways at all levels from the olfactory receptors to the central nervous system, and simulate to some extent the operation of these blocks, that would allow to approach the sensing performance known in biological olfactory system of animals. New technical requirements arise to the hardware and software equipment used in such machine olfaction experiments. This work explores the bioinspired approach to machine olfaction in depth on the technological side. At the hardware level, the embedded computer is assembled, being the core part of the experimental set up. The embedded computer is interfaced with two main biomimetic modules designed by the collaborators: a large-scale sensor array for emulation of the population of the olfactory receptors, and a mobile robotic platform for autonomous experiments for guiding olfactory behaviour. At the software level, the software development kit is designed to host the neuromorphic models of the collaborators for processing the sensory inputs as in the olfactory pathway.
Virtualization of the set up was one of the key engineering solutions in the development. Being a device, the set up is transformed to a virtual system for running data simulations, where the software environment is essentially the same, and the real sensors are replaced by the virtual sensors coming from especially designed data simulation tool. The proposed abstraction of the set up results in an ecosystem containing both the models of the olfactory system and the virtual array.
This ecosystem can loaded from the developed system image on any personal computer. In addition to the engineering products released in the course of thesis, the scientific results have been published in three journal articles, two book chapters and conference proceedings. The main results on validation of the set up under the scenario of robotic odour localization are reported in the book chapters. The series of three journal articles covers the work on the data simulation tool for machine olfaction: the novel model of drift, the models to simulate the sensor array data based on the reference data set, and the parametrized simulated data and benchmarks proposed for the first time in machine olfaction.
This thesis ends up with a solid foundation for the research in biomimetic simulations and algorithms on machine olfaction. The results achieved in the thesis are expected to give rise to new bioinspired applications in machine olfaction, which could have a significant impact in the biomedical engineering research area.Esta tesis se enmarca en el campo de bioingeneria, mas particularmente en la configuración de un sistema experimental de sensores de gases químicos. Quizás más que en cualquier otra modalidad de sensores, los sensores químicos representan un conjunto de retos técnicos y conceptuales ya que deben lidiar con problemas como su baja especificidad, su respuesta temporal lenta, su inestabilidad a largo plazo, su alto consumo enérgético, su portabilidad, así como la necesidad de un sistema de datos y código robusto. En la última década, se ha observado una clara tendencia por parte de los sistemas de machine olfaction hacia la imitación del sistema de olfato biológico de insectos y mamíferos. Los diseñadores de estos sistemas se inspiran del sistema olfativo biológico, ya que los animales cumplen, sin apenas esfuerzo, algunos de los escenarios no resueltos en machine olfaction. Por ejemplo, las polillas machos recorren largas distancias para localizar las polillas hembra, detectando sus feromonas de forma rápida y robusta. La detección biomimética de gases químicos tiene como objetivo identificar los elementos fundamentales de la vía olfativa a todos los niveles, desde los receptores olfativos hasta el sistema nervioso central, y simular, en cierta medida, el funcionamiento de estos bloques, lo que permitiría acercar el rendimiento de la detección al rendimiento de los sistemas olfativos conociodos de los animales. Esto conlleva nuevos requisitos técnicos a nivel de equipamiento tanto hardware como software utilizado en este tipo de experimentos de machine olfaction. Este trabajo propone un enfoque bioinspirado para la ¿machine olfaction¿, explorando a fondo la parte tecnológica. A nivel hardware, un ordenador embedido se ha ensamblado, siendo ésta la parte más importante de la configuración experimental. Este ordenador integrado está interconectado con dos módulos principales biomiméticos diseñados por los colaboradores: una matriz de sensores a gran escala y una plataforma móvil robotizada para experimentos autónomos. A nivel software, el kit de desarrollo software se ha diseñado para recoger los modelos neuromórficos de los colaboradores para el procesamiento de las entradas sensoriales como en la vía olfativa biológica. La virtualización del sistema fue una de las soluciones ingenieriles clave de su desarrollo. Al ser un dispositivo, el sistema se ha transformado en un sistema virtual para la realización de simulaciones de datos, donde el entorno de software es esencialmente el mismo, y donde los sensores reales se sustituyen por sensores virtuales procedentes de una herramienta de simulación de datos especialmente diseñada. La propuesta de abstracción del sistema resulta en un ecosistema que contiene tanto los modelos del sistema olfativo como la matriz virtual . Este ecosistema se puede cargar en cualquier ordenador personal como una imagen del sistema desarrollado. Además de los productos de ingeniería entregados en esta tesis, los resultados científicos se han publicado en tres artículos en revistas, dos capítulos de libros y los proceedings de dos conferencias internacionales. Los principales resultados en la validación del sistema en el escenario de la localización robótica de olores se presentan en los capítulos del libro. Los tres artículos de revistas abarcan el trabajo en la herramienta de simulación de datos para machine olfaction: el novedoso modelo de drift, los modelos para simular la matriz de sensores basado en el conjunto de datos de referencia, y la parametrización de los datos simulados y los benchmarks propuestos por primera vez en machine olfaction. Esta tesis ofrece una base sólida para la investigación en simulaciones biomiméticas y en algoritmos en machine olfaction. Los resultados obtenidos en la tesis pretenden dar lugar a nuevas aplicaciones bioinspiradas en machine olfaction, lo que podría tener un significativo impacto en el área de investigación en ingeniería biomédica

A preliminary study, conducted the fall of 2012, formed the basis for this master thesis. The thesis is issued by NTNU, and it is a part of a project in which Searis AS, Troms Kråkebolle and Norway Sea Urchins are participants. Searis AS is a start-up company, in which the student is a participant. Troms Kråkebolle and Norway Sea Urchins perform aquaculture farming, and wild catch, of sea urchins, respectively.The project was initated because of the need to automate the manual grading of sea urchins. The grading process is time consuming and increase cost for the customer. The grading involves sorting the sea urchins by their shell diameter, and removing foreign objects like stones.An iterative product development process formed the foundation for the results in this thesis. The process consited of; analysing user and customer needs and requirements, problem decomposition, development of solutions, ranking and rating, breakdown of principal solutions, tests, discussion and choice of concepts. Input for the designprocess was based on discussion with pilot customers; Troms Kråkebolle and Norway Sea Urchin, creative sessions with Searis AS, search for competitive products, computer simulations, and lab experiments.A complete system for the grading of sea urchins is proposed at principal level, and design for the for critical components of an automated grading machine is presented.The result of the thesis is a CAD?modell of a prototype of a grading machine. The CAD-modell consists of dimensions, materials, components, and assembly, and is a sketch on how a the prototype can be constructed.Experiments and simulations have strengthened the confidence in the solutions. And it is concluded that the design proposed in this thesis will be able to cover the needs for the customers.There is still parts that needs development before a complete prototype can be constructed.

Working sets are sets of pages that have been most recently accessed by virtual machines (VMs). They are often used within the memory scheduler of a hypervisor to estimate the memory demands of VMs running on the hypervisor. In order to manage the memory resources of the hypervisor efficiently, it is essential that these working set sizes be estimated accurately at any given point in time. Currently, a statistical sampling strategy is used within VMware ESX hypervisors to estimate the working set sizes of VMs. Using this technique, a small number of random pages is selected to form a sample set. Access to these sampled pages is then tracked and the percentage of sampled pages that are accessed is used to estimate the working set size of a VM. This technique, though simple, does not provide a very accurate estimation of the working set size. A more promising tool that can be used to accurately estimate the working set size of a VM is a miss ratio curve (MRC). An MRC is a curve that plots the predicted miss ratio of a VM against the total available memory given to the VM. Even though MRCs can estimate working set sizes of VMs with much better accuracy, they are still not widely used in practice because building these curves incurs too much overhead, thus affecting the overall system performance. However, a recent study has found a way to reduce the cost of building these curves, making them a promising tool that can be used to estimate working set sizes. In this thesis, I propose that MRCs be used as an alternative to the statistical sampling strategy currently employed within VMware ESX. I will demonstrate how to apply the state of the art technique found in the recent study to construct accurate MRCs without incurring too much overhead, and use these curves to track working set sizes of VMs. I will also show that these curves can estimate working set sizes of VMs with much better accuracy than the statistical sampling strategy.

AbstractThe sex tech industry is set to experience significant changes as it grows in value and attracts more users. The industry is often divided into five main branches: remote sex, robots, immersive entertainment, virtual sex, and augmentation. Virtual reality (VR) technology has the potential to transform sexual experiences, allowing people to explore different identities and experiment with new sensations. Haptic and multisensory experiences will revolutionize virtual sex, and virtual sexology will enhance people's sexual skills. The COVID-19 pandemic has had an impact on sexual lives, with people turning to sexting and sex toys. The article explores the possibility of humans falling in love, marrying, having sex with robots, and merging with machines. VR contact lenses may even enable dream-based sex. However, the article notes that human touch and contact remain crucial in sexual experiences and technology cannot fully replace them. Despite new technological developments the future of sex will continue to be about the pursuit of pleasure, while genuine human relationships will remain essential.

Nowadays farm machinery is incorporating new subsystems for the interchange of data between different mobile equipment and also with the base office. Such systems allow to know in real time basic information about how tasks are being performed in the field (where each tractor and machine is located, surface coverage, dose applied, fuel usage, etc. ) but also allow proper synchronization between machines working together (such a combine and a set of supporting trucks). The analysis and management of this information is important for the optimization of field tasks.

Full textAbstract:
This paper presents a revolutionary approach of using a fluid-lubricated bearing for both traditional functions (load support, damping, and heat removal) and to actively control the rotor dynamics of rotating machinery. We will discuss how its use in the design of next generation turbomachinery can yield dramatic benefits. This includes an increase in efficiency, operational life, fault diagnostic, and reductions in machine size, weight, and cost. With the use of hydrostatic instead of hydrodynamic lubrication, traditional lubricants can be replaced by fluids more friendly to the process and environment. In this paper a comparison between the new hydrostatic bearing (Bently ServoFluid™ Control Bearing) and active magnetic bearings (AMB) will be presented. The Bently ServoFluid™ Control Bearing is an active controlled externally pressurized (a hybrid hydrostatic) bearing using fluid restoring force to compensate for rotor-related forces. It has the positive features of rolling element, fluid film and magnetic bearings with fewer negative attributes. The fluid restoring forces provide static and dynamic motion control similar to magnetic bearings, but with significantly larger compensation forces and with higher stiffness control. This revolutionary approach enables machinery owners to identify, understand and compensate for rotor system forces, an improvement over simply using vibration (motion) information for machinery diagnostics. This allows more complete diagnostics and prognostics of machine health. The bearing can be used to apply known perturbation forces to the rotor. Perturbation forces enable the determination of rotor system stiffness, and subsequent changes, thus improving machinery diagnostics. It can also provide information, such as the mechanical parameters governing the motion, system linearity, and stability margins for more accurate modeling of machines. Test results will be included to show experimentally determined transfer functions of each of the control loop elements, and predicted rotor forces. A typical root locus plot will be shown demonstrating how the characteristics change with bearing stiffness. Prototype machines, with both low viscosity fluid (water) and typical viscous fluid (T-10 turbine oil), have been built, tested, and successfully operated.

In the previous two decades, multiphase electrical machines have been recognized as a viable solution for modern applications such as electric vehicles and renewable energy sources. The advantages of multiphase machines compared to their three- phase counterparts include higher torque density, improved fault tolerance, and lower rated power of power switching devices. Considering the tendency for greater inclusion of multiphase machine, great efforts are invested in their modelling and control. This paper proposes a simplified magnetic circuit model of an asymmetrical six-phase machine. The model outputs field distribution in the machine’s magnetic circuit and winding fluxes and inductances while including saturation effects. The results of the proposed model are verified via comparison with results obtained using the finite element method. The simplified model is shown to provide satisfying accuracy, while being immensely more computationally efficient compared to the finite element model

Full textAbstract:
The paper presents a method of determining the pressure ratio characteristic of a compressible flow turbo-machine when the specific heat ratio of the gas flowing through it is changed. It is shown that Mach number scaling in efficient machines running at low fractional increases in total temperature could tolerate limited variations in specific heat ratio. A method of finding the scaled operating conditions for the achievement of similar density ratios in scaled and prototype machines operating with gases with different specific heat ratios is presented. The method achieved very good accuracy in scaling the performance of a centrifugal impeller working with argon to its performance with carbon dioxide. The stage polytropic efficiencies were chosen to agree with measured data, although analysis indicated that polytropic stage efficiency should be independent of specific heat ratio. Further investigation and validation may lead to a standardised method of scaling turbo-machinery performance between gases with varying properties, which includes the effect of specific heat ratio.

Full textAbstract:
This work introduces a new class of kernel machines: the Support fuzzy-sets machines. This machines can be used to solve machine learning tasks, like classification, regression or clustering, on data with point-wise uncertainty. We advocate the use of fuzzy set for modeling the uncertainty around the vicinity of observations, and for incorporating those uncertainties into the learning machine. Support fuzzy-sets machines are defined by kernel gram (covariance) matrices defined by kernel on fuzzy sets, which are special kind of real-valued (kernel) functions whose domain is the set of all fuzzy sets, i.e., k : X × X → R, where X is a fuzzy set. Under fuzzy set modeling, such kernels can be used to estimate covariance matrices for observations with point-wise uncertainty and for estimating similarity measures for that kind of data. Previous research showed in fact, an improved performance in learning machines when is considered the information given by the neighborhood around observations, see for example local learning [Bottou and Vapnik, 1992], Vicinal kernels [Vapnik, 1995], Vicinal risk minimization [Chapelle et al., 2001] and the RBF network. More recent approaches consider kernel machines defined by kernels on probability measures [Muandet et al., 2012]. Support Fuzzy-set Machines thanks to the reproducing theorem of kernel methods learn f = Pi αik(X,) in a high dimensional Hilbert space called Reproducing Kernel Hilbert Space, where the support fuzzy-sets is the set given by all the fuzzy sets such the correspondent αi > 0. Several positive definite kernels on fuzzy sets can be used for training the proposed kernel machines, as for example: The cross product kernel on fuzzy sets [Guevara et al., 2017], the intersection kernel on fuzzy sets, [Guevara et al., 2014], the non-singleton kernel on fuzzy sets, [Guevara et al., 2013] or the Distance-based kernels on fuzzy sets ([Guevara et al., 2015]).

Such an approach to a set of machines operating in similar conditions allows for a multivariate analysis for condition monitoring based on a single machine as well as based on group analysis. This paper describes an Industrial Internet-of-Thing (IIoT) concept for condition monitoring of machinery population based on water pumps. The first part provides an introduction to unsupervised anomaly detection based on population modeling with using features calculated from the: mechanical (based on vibration sensors), electrical (voltage and current signals collected from electric motors that drive monitored pumps) and operational processes (such as pressures, flows) signals. Finally, the preliminary results from laboratory testing and demonstration at a wastewater processing plant are presented.

The use of machinery protection systems is well-established in industry. These systems shut down a machine or return it to a safe or nondestructive mode of operation without human intervention. Protection systems are used to ensure personnel safety, prevent or minimize machine damage, and limit environmental impact. While these are substantial benefits, machinery protection remains inherently reactive, and the approach is still necessary, but no longer sufficient in today’s economic environment. Machinery management is increasingly recognized for its ability to indicate machinery condition before a protection system’s alarm levels are exceeded. By providing an early warning of what is happening with the machine, proactive decisions can be made about how machinery assets are run and how they affect the plant. Machinery management requires the correlation of critical process data with vibration and position data. It allows event correlation and effective root cause analysis. Information resulting from effective machinery management is actionable because it results from continuous online audits of machinery, and indicates when action is required and how best to take it. Machinery management helps answer key questions, such as: How long can this machine run? Can the process be adjusted to extend the operation and avoid a shutdown? If you want to proactively manage machinery and optimize machinery performance along with the process, you must have an effective machinery management program. This paper explores the practice of machinery management, including what it is, what is considered “best practice,” and what the resulting benefits are.

Abstract Using a library of machine modules, modular machine tools are being developed by many machine tool manufacturers to reduce design lead time. To accommodate frequent changes in product design in a timely and cost-effective manner, the next generation of machine tools should be reconfigurable to process a family of products. This enables reduction not only in machine design lead time but more significantly a reduction in machine set-up and ramp-up time. The essential characteristics of Reconfigurable Machine Tools (RMTs) include modularity, convertibility, flexibility, and cost-effectiveness. Currently there is no systematic method of designing modular machines, let alone reconfigurable machines. This paper presents a methodology for kinematic synthesis of machine tools using screw theory. The motion characteristics of a set of desired machining tasks as well as stored library of machine modules are captured in a common representation scheme. A simple design example to illustrate the application of this methodology for systematic selection and synthesis of reconfigurable machine tools is presented. The proposed methodology can be extended to include the dynamic characteristics and control schemes to enable integrated design of machines and controllers.

Our objective of this work was to investigate exclusively Daniel USMs. Sixty five thousand individual data points were used in MLA development which totaled over 18 hours of USM data from seven experimental data sets generated at three flow facilities. Six disturbance types were investigated (baseline, single elbow, double elbow out of plane, liquid, elbow header, and tee header). All experimental data was labeled with the disturbance type, if any, and deviation from baseline error. The MLA feature set was improved from the 2015 work by using gas flow conditions to compare measured and predicted flow velocities (flow profiles) and adding features that quantify the stability of the USM flow measurement. Supervised clustering and regression algorithms were fit to the labeled USM data and the accuracy of the MLAs was calculated using a cross-validation technique.

Full textAbstract:
Objective: To compare the performance of popular machine learning algorithms (ML) in mapping the sensorimotor cortex (SM) and identifying the anterior lip of the central sulcus (CS). Methods: We evaluated support vector machines (SVMs), random forest (RF), decision trees (DT), single layer perceptron (SLP), and multilayer perceptron (MLP) against standard logistic regression (LR) to identify the SM cortex employing validated features from six-minute of NREM sleep icEEG data and applying standard common hyperparameters and 10-fold cross-validation. Each algorithm was tested using vetted features based on the statistical significance of classical univariate analysis (p<0.05) and extended () 17 features representing power/coherence of different frequency bands, entropy, and interelectrode-based distance. The analysis was performed before and after weight adjustment for imbalanced data (w). Results: 7 subjects and 376 contacts were included. Before optimization, ML algorithms performed comparably employing conventional features (median CS accuracy: 0.89, IQR [0.88-0.9]). After optimization, neural networks outperformed others in means of accuracy (MLP: 0.86), the area under the curve (AUC) (SLPw, MLPw, MLP: 0.91), recall (SLPw: 0.82, MLPw: 0.81), precision (SLPw: 0.84), and F1-scores (SLPw: 0.82). SVM achieved the best specificity performance. Extending the number of features and adjusting the weights improved recall, precision, and F1-scores by 48.27%, 27.15%, and 39.15%, respectively, with gains or no significant losses in specificity and AUC across CS and Function (correlation r=0.71 between the two clinical scenarios in all performance metrics, p<0.001). Interpretation: Computational passive sensorimotor mapping is feasible and reliable. Feature extension and weight adjustments improve the performance and counterbalance the accuracy paradox. Optimized neural networks outperform other ML algorithms even in binary classification tasks. The best-performing models and the MATLAB® routine employed in signal processing are available to the public at (Link 1).

ERDC-Geo is a surface erodibility parameterization developed to improve dust predictions in weather forecasting models. Geomorphic landform maps used in ERDC-Geo link surface dust emission potential to landform type. Using a previously generated southwest United States landform map as training data, a classification model based on machine learning (ML) was established to generate ERDC-Geo input data. To evaluate the ability of the ML model to accurately classify landforms, an independent reference landform data set was created for areas in the Chihuahuan Desert. The reference landform data set was generated using two separate map-ping methodologies: one based on in situ observations, and another based on the interpretation of satellite imagery. Existing geospatial data layers and recommendations from local rangeland experts guided site selections for both in situ and remote landform identification. A total of 18 landform types were mapped across 128 sites in New Mexico, Texas, and Mexico using the in situ (31 sites) and remote (97 sites) techniques. The final data set is critical for evaluating the ML-classification model and, ultimately, for improving dust forecasting models.

Full textAbstract:
Concepts for real-time grading of fruits and vegetables were developed, including multi-spectral imaging with structured illumination to detect and distinguish surface defects from concavities. Based on these concepts, a single-lane conveyor and inspection system were designed and evaluated. Image processing algorithms were developed to inspect and grade large quasi-spherical fruits (peaches and apples) and smaller dried fruits (dates). Adjusting defect pixel thresholds to achieve a 25% error rate on good apples, classification errors for bruise, crack, and cut classes were 51%, 42%, and 46%, respectively. Comparable results for bruise, scar, and cut peach clases were 48%, 22%, and 58%, respectively. Acquiring more than two images of each fruit and using more than six lines of structured illumination per fruit would reduce sorting errors. Doing so, potential sorting error rates for bruise, crack, and cut apple classes were estimated to be 38%, 38%, and 33%, respectively. Similarly, potential error rates for the bruitse, scar, and cut peach classes were 9%, 3%, and 30%, respectively. Date size classification results were good: 68% within one size class and 98% within two size classes. Date quality classification results were not adequate due to the problem of blistering. Improved features were discussed. The most significant contribution of this research was the on-going collaboration with producers and equipment manufacturers, and the resulting transfer of research ideas to expedite the commercial application of machine vision for postharvest inspection and grading of agricultural products.

This paper estimates the effects of equipment investment on relative wages and employment of skilled labor and explores their dynamics. The basic hypothesis is that they are positive, due to either equipment-skill complementarity or to skill advantage in technology adoption. Using a panel data set with a wide rage of countries, the relative wage and relative employment of skilled workers are regressed on lagged investment in machinery and other relevant variables. The results indicate a strong, positive effect of machinery investment on the relative demand for skilled labor.

Full textAbstract:
Lorsque Neal Stephenson a introduit le terme « métavers » dans son roman de science-fiction Snow Crash, en 1992, il était loin de se douter que le mot allait susciter autant de discussions. La notion d’une réalité d’un type nouveau, qui serait synthétisée, puis virtualisée et librement socialisée, est fascinante par ce qu’elle exigerait aux plans scientifique et technique. Fascinante surtout par ses retombées éventuelles aux niveaux culturel et social, y compris de nature éthique (qui ne sont pas abordées ici). Ce texte rappelle brièvement l’origine du concept avant de se consacrer à ses requis et défis techniques, abordés en l’examinant comme un système avancé d’information et communication. Le métavers revêt une complexité inédite alors que les capacités cognitives de l’humain et de la machine sont appelées à se fusionner avec synergie. L’analyse – qui demeure succincte compte tenu du format d’un article court – permettra de comprendre comment et pourquoi le métavers, dans la mouture originale proposée par Stephenson, demeure une utopie. Mais aussi comment l’élimination de certains requis peut permettre d’en retenir une saveur intéressante, laquelle apparait déjà dans une multitude d’applications.
