This paper suggests a hypothesis about the nature “Psi”; psychical experience. The suggested hypothesis concluded from rational logical introduction and related studies, as well. By inductive methodology, concluded from this paper that we are all linked to coherent neural networks that work in synchronized and reciprocal way. Our mirror neurons resonate and synchronize actions to join us with the whole, at anytime, anywhere, causing communication obviously noticed in Psi experiences. This communication happens when we have massive, urgent need with no ability to feed by regular ordinary daily common ways.

Full textAbstract:
In this study, we propose a method for extracting the characteristics of body motions that contribute to reducing the takt time in a cooperative task between a dishwashing robot and a human operator. The proposed method collects the takt time and motion data from novice operators until they become experienced using an inexpensive acceleration sensor. The operation data is classified into experienced and novice periods using the variance value of the takt time. In addition, the Hidden Markov Model is generated to classify the motion data into multiple motion phases. The motion features of the operator are extracted for each phase from the generated model. The proposed method finds the motion features whose difference between the experienced and novice periods are similar to the takt time transition. It uses them as important variables. We verified the effectiveness of the proposed method by conducting experiments that simulate actual work at a restaurant. The Hidden Markov Model classified the operation phases into three categories with the AUC of 0.9. In all samples, we were able to extract the motion characteristics of the experienced operators. This study showed the potential to improve the speed of novice's progress by the extracted motion characteristics to improve education guidelines and to show operators how they should physically move.

Full textAbstract:
This article proposes new methods for enhancing the active harvest of piezoelectric energy using the synchronized switch harvesting on inductor (SSHI) technique. It was experimentally confirmed that the energy harvested by the original synchronized switch harvesting on inductor technique was decreased by the suppression of the vibration amplitude, and this critical problem was solved by developing new control strategies, namely, switch harvesting considering vibration suppression (SCVS) and adaptive SCVS (ASCVS). The SCVS technique was designed to intentionally skip some of the switching actions of the original synchronized switch harvesting on inductor technique, while the ASCVS technique enables more flexible variation of the number of skipped switching actions. The skipping of the switching actions facilitates the recovery of the vibration amplitude produced by the excitation force, and the developed strategies thus maintain the vibration amplitude at the highest possible level, resulting in increased energy harvest. The results of the experimental implementation of the proposed strategies showed that they enabled the harvesting of as much as 10.5 times the energy harvested by the original synchronized switch harvesting on inductor technique. The ASCVS technique particularly enables flexible enhancement of the harvested energy under various vibration conditions.

Full textAbstract:
Sense of agency, the experience of controlling external events through one's actions, stems from contiguity between action- and effect-related signals. Here we show that human observers link their action- and effect-related signals using a computational principle common to cross-modal sensory grouping. We first report that the detection of a delay between tactile and visual stimuli is enhanced when both stimuli are synchronized with separate auditory stimuli (experiment 1). This occurs because the synchronized auditory stimuli hinder the potential grouping between tactile and visual stimuli. We subsequently demonstrate an analogous effect on observers' key press as an action and a sensory event. This change is associated with a modulation in sense of agency; namely, sense of agency, as evaluated by apparent compressions of action–effect intervals (intentional binding) or subjective causality ratings, is impaired when both participant's action and its putative visual effect events are synchronized with auditory tones (experiments 2 and 3). Moreover, a similar role of action–effect grouping in determining sense of agency is demonstrated when the additional signal is presented in the modality identical to an effect event (experiment 4). These results are consistent with the view that sense of agency is the result of general processes of causal perception and that cross-modal grouping plays a central role in these processes.

Full textAbstract:
Magicians use several techniques to deceive their audiences, including, for example, the misdirection of attention and verbal suggestion. We explored another potential stratagem, namely the relaxation of attention. Participants watched a video of a highly skilled magician whilst having their eye-blinks recorded. The timing of spontaneous eye-blinks was highly synchronized across participants. In addition, the synchronized blinks frequency occurred immediately after a seemingly impossible feat, and often coincided with actions that the magician wanted to conceal from the audience. Given that blinking is associated with the relaxation of attention, these findings suggest that blinking plays an important role in the perception of magic, and that magicians may utilize blinking and the relaxation of attention to hide certain secret actions.

Full textAbstract:
Many common behaviours require people to coordinate the timing of their actions with the timing of others' actions. We examined whether representations of musicians' actions are activated in coperformers with whom they must coordinate their actions in time and whether coperformers simulate each other's actions using their own motor systems during temporal coordination. Pianists performed right-hand melodies along with simple or complex left-hand accompaniments produced by themselves or by another pianist. Individual performers' preferred performance rates were measured in solo performance of the right-hand melody. The complexity of the left-hand accompaniment influenced the temporal grouping structure of the right-hand melody in the same way when it was performed by the self or by the duet partner, providing some support for the action corepresentation hypothesis. In contrast, accompaniment complexity had little influence on temporal coordination measures (asynchronies and cross-correlations between parts). Temporal coordination measures were influenced by a priori similarities between partners' preferred rates; partners who had similar preferred rates in solo performance were better synchronized and showed mutual adaptation to each other's timing during duet performances. These findings extend previous findings of action corepresentation and action simulation to a task that requires precise temporal coordination of independent yet simultaneous actions.

Full textAbstract:
Background Thiopental produces a concentration-dependent continuum of effects on the cortical electroencephalogram (EEG) that has been linked to behavioral measures of anesthetic depth. The complexity of the response, however, limits a clear insight into the neurophysiologic actions of thiopental. The current study investigated thiopental actions on cortical EEG and hippocampal electrical activity, to determine whether similar effects occur on both structures and to compare synchronized activity between these structures. Methods Thiopental was administered intravenously via an implanted catheter in freely moving rats. Arterial blood oxygen/carbon dioxide concentration, thiopental concentrations, and temperature were monitored and controlled. Neocortical EEG was recorded from implanted dural surface electrodes and hippocampal neuron electrical activity was recorded from stereotaxically placed microelectrodes. Pharmacokinetic models were used to determine effect site concentrations. Results Thiopental produced an increase in EEG frequency and amplitude at low concentrations (15-20 micrograms/ml total plasma, approximately 10 microM unbound), which produced a loss of righting reflex. This was followed by a frequency decrease and burst suppression activity at higher concentrations (50-80 micrograms/ml, approximately 60 microM), which produced a loss of tail pinch and corneal reflexes. Higher concentrations of thiopental ( > 60 micrograms/ml) uncoupled synchronized burst discharges recorded in hippocampus and cortex. Isoelectric EEG activity was associated with concentrations of 70-90 micrograms/ml (approximately 80 microM) and a deep level of anesthesia; motor reflexes were abolished, although cardiovascular reflexes remained. In all frequency bands, similar concentration-EEG effect relationships were observed for cortical and hippocampal signals, only differing in the magnitude of response. A reversed progression of effects was observed on recovery. Conclusions The results confirm earlier findings in humans and animals and demonstrate that both the hippocampus and neocortex exhibit burst suppression and isoelectric activity during thiopental anesthesia. Thiopental-induced synchronized burst activity was depressed by progressively higher concentrations. The lost synchronization suggests a depression of synaptic coupling between cortical structures contributes to anesthesia.

Background Anesthetic depth after barbiturate administration has been correlated with distinct electroencephalogram (EEG) patterns. The current study used a rat neocortical brain slice micro-EEG preparation to investigate synaptic mechanisms underlying thiopental-induced transitions in synchronized neuronal activity. Methods Concentration-dependent cellular actions of thiopental were investigated in brain slices using specific pharmacologic probes, whole cell patch clamps, and extracellular field recordings. Theta-Like micro-EEG oscillations were elicited in neocortical slices by mimicking subcortical cholinergic and gamma-aminobutyric acid (GABA) afferent input with carbachol (100 microM), a cholinergic agonist, and bicuculline (10 microM) a GABAA antagonist. Results In the presence of 20 microM thiopental, micro-EEG slowing from theta (7.3 +/- 0.9 Hz, mean +/- SD, n = 19) to delta frequencies (2.5 +/- 0.5 Hz, n = 11) was associated with a threefold prolongation of inhibitory currents. Burst suppression activity occurred at 50 microM thiopental, and appeared to result from direct activation of GABAA-gated chloride currents, observed with voltage clamp recordings, and mimicked with a direct acting GABAA agonist, muscimol (1 microM). Isoelectric activity occurred at 100 microM thiopental, and likely resulted from reduced glutamatergic transmission, evidenced by depressed excitatory postsynaptic potentials. Glutamatergic excitation was required for burst suppression activity, because glutamate receptor antagonists blocked thiopental-induced bursts; forcing a transition to isoelectric activity. Conclusions Thiopental produced a continuum of EEG-like states in brain slices similar to those observed in vivo. The progression of thiopental-induced effects appear to have resulted from specific cellular actions that were recruited in a concentration-dependent manner. Progressive enhancement of synaptic inhibition followed by depression of excitatory transmission led to micro-EEG frequency slowing, burst suppression, and isoelectric activity.

Full textAbstract:
Dans un environnement en constant changement, les fonctions exécutives (FRE) nous permettent d'organiser l'information en provenance de sources multiples, de s'adapter à des situations sociales complexes et d'inhiber les comportements inappropriés. Les recherches sur le fonctionnement exécutif ont été initiées en neuropsychologie, après avoir observé chez des patients frontaux, des difficultés à organiser leurs comportements quotidiens sans pour autant présenter de difficultés de langage ou de mémoire. Un grand nombre de tests neuropsychologiques sont disponibles afin d'évaluer les FE. Cependant, ces tests sont souvent critiqués pour leur complexité et leur manque de validité de construction. Le champ des FE manque en réalité de modèles théoriques précis qui permettraient de décrire ces fonctions et leurs potentielles interactions pour le contrôle des comportements complexes. En conséquence, les tâches sont souvent construites de manière intuitive, dans le présent travail de thèse, après revue d'un état de l'art sur les FE (Ch1), je propose une nouvelle tâche, le spatial-tapping, qui pourrait être utilisée en remplacement des tâches classiques complexes (Ch2). Je promeus également le potentiel de cette tâche à être utilisée dans des contextes cliniques (Ch3). Je présente finalement comment les analyses réalisées pour le spatial-tapping afin d'étudier les FE peuvent être transférées à des situations motrices plus complexes, comme la coordination bi-manuelle (Ch4). En conclusion, les résultats présentés dans ce travail de thèse sont en faveur de l'idée selon laquelle notre organisation mentale reflète la manière dont on organise nos mouvementsIn a constant changing environment, executive abilities allow us to organize sensory information of multiple sources and to adapt to diverse stuations while at the same time inhibiting inappropriate behaviors. research on the executive functions (EFS) have historical roots on neuropsychology, with the description of frontal patients that were showing disruptions in organizing their daily behaviors independently of any impairment in memory, language or general intelligence. A wide range of neuropsychological tools is used today to evaluate executive abilities : tower of London for planning, go-no-go for inhibition, etc. However, the classical tasks often present methodological limitations and they lack of correpondence between process and behavior. Furthermore, the field lacks of a compelling theory that make links between the EFS themselves. The present PHD work was an attempt to propose a novel task to assess the EFS in the place of the classical batteries of neuropsychological tasks. After offering an overview of the EF literature and presenting simple motor tasks that seem to target similar EFS than those described in neuropsychology (Ch1), I present the spatial-tapping task as a challenging paradigm to understand the relationships between the different EFS (Ch2), and its potential to be used in clinical settings (Ch3). The I present how a similar approach can be used to investigate how EFS intervenes in the control of more complex motor sequences, E.G. bi-manual tasks (Ch4). Overall, the results presented here support an emboided perspective of cognition with mental organization reflecting the way one plans motor sequences for adaptive behavior

Full textAbstract:
Dans cette thèse, nous présentons un cadre théorique pour étudier les systèmes de particules actives fonctionnant avec une quantité discrète d'états internes qui contrôlent le comportement externe de ces objets. Les concepts théoriques développés dans cette thèse sont introduits afin de comprendre un grand nombre de systèmes biologiques multi-agents dont les individus présentent différents types de comportements se succédant au cours du temps. Par construction, le modèle théorique suppose que l'observateur extérieur a accès uniquement au comportement visible des individus, et non pas à leurs états internes. C'est seulement après une étude détaillée de la dynamique comportementale que l'existence de ces états internes devient évidente. Cette analyse est cruciale pour pouvoir associer les comportements observés expérimentalement avec un ou plusieurs états internes du modèle. Cette association entre les états et les comportements doit être faite selon les observations et la phénoménologie du système biologique faisant l'objet de l'étude. Les scénarios qui peuvent être observés en utilisant notre modèle théorique sont déterminés par la conception du mécanisme interne des individus (nombre d'états internes, taux de transition, etc…) et seront de nature markovienne par construction. Tous les travaux expérimentaux et théoriques contenus dans cette thèse démontrent que notre modèle est approprié pour décrire des systèmes réels montrant des comportements intermittents individuels ou collectifs. Ce nouveau cadre théorique pour des particules actives avec états internes, introduit ici, est encore en développement et nous sommes convaincus qu'il peut potentiellement ouvrir de nouvelles branches de recherche à l'interface entre la physique, la biologie et les mathématiquesIn this thesis we introduce a theoretical framework to understand collections of active particles that operate with a finite number of discrete internal states that control the external behavior of these entities. The theoretical concepts developed in this thesis are conceived to understand the large number of existing multiagent biological systems where the individuals display distinct behavioral phases that alternate with each other. By construction, the premise of our theoretical model is that an external observer has access only to the external behavior of the individuals, but not to their internal state. It is only after careful examination of the behavioral dynamics that the existence of these internal states becomes evident. This analysis is key to be able to associate the experimentally observed behaviors of individuals with one or many internal states of the model. This association between states and behaviors should be done accordingly to the observations and the phenomenology displayed by the biological system that is being the subject of study. The possible scenarios that can be observed using our theoretical model are determined by the design of the internal mechanism of the individuals (number of internal states, transition rates, etc...) and will be of markovian nature by construction. All the experimental and theoretical work contained in this thesis is evidence that our model is suitable to be used to describe real-life systems showing individual or collective intermittent behaviors. This here-introduced new framework of active particles with internal states is still in development and we are convinced that it can potentially open new branches of research at the interface between physics, biology and mathematics

Full textAbstract:
Change is the first part of the change-balance-liberation trilogy. Humans are the ones to observe and act upon the inevitable changes. Not admitting change is ignorance. Actions in change need to make sense. Humans may act in avoidance, in passivity, or in proactivity along with various changes. Musical and music educational experiences are no exception. Musicians and music educators are expected to change their actions in anticipation or in response to the constant changing situations. The author discusses change in the framework of the four complementary bipolar continua and how changes are synchronized with or without meanings. The importance of understanding change is to understand the changing needs of humans, in music, music education, and otherwise. Humans are able to move across the zones of musical avoidance, musical passivity, and musical proactivity depending on their changing life circumstances.

This chapter locates ballroom dance's transformative potential in the affective experience of synchronized performance, with particular emphasis on how it brings pleasure and feeling of well-being to the dancer. It examines the radical shift in awareness that occurs during the dance event itself, where feelings of joy and euphoria displace feelings of self-consciousness and worry over everyday life. It considers Mihaly Csikszentmihalyi's concept of optimal experience and flow in order to understand the events that can lead to such states of awareness as well as appreciate the appeal of ballroom dance as play. It also discusses the notion, advanced by Csikszentmihalyi and Stith Bennett, that play is grounded in the “concept of possibility” and is action that generates action, creating a unified experience flowing from one moment to the next. The chapter argues that flow and flow states generate feelings of positive personal transformation, of becoming beautiful.

Full textAbstract:
Why does the mind matter for joint action? Contentious Minds is a comparative study of how cognitive and relational processes allow activists to sustain their commitment. With survey data and narratives of activists engaged in three commitment communities, the minds of activists involved in contentious politics are compared with those devoted to institutional and volunteering action. The book’s main argument is that activists of one commitment community have synchronized minds concerning the aim and means of their activism as they perceive common good (aim) and politics (means) through similar cognitive lenses. The book shows the importance of direct conversational contact with individuals in bringing about this synchronization. Assessing the synchronization within communities as well as the variation between them constitutes a major purpose of this book. It shows that activists construct and enact community-specific democratic cultures, thereby entering the public sphere through collective action. The book makes three major contributions. First, it emphasizes the necessity to return the study of the mind to research on activism, Second, it calls for an integrated relational perspective that rests on the structural, instrumental, and interpretative dimensions of social networks. Finally, it advocates a substantial integration of culture in the study of social movements by effectively valuing the role of culture in shaping a person’s mind.

AbstractRobotics researchers are spending many efforts in developing methodologies and techniques that allow robots to work side by side with humans, with the aim of improving the manufacturing processes. Such a level of interaction does not require just the safe coexistence in a common space, which is something completely achieved by the current state of the art. In scenarios like co-assemblies, humans and robots have to execute alternating tasks, with the aim of realizing a set of possible finite products. This requires the robots to adapt, synchronize and actively cooperate with the humans. This work will show that this goal can be reached by providing the cobots with three main abilities: recognizing the human behaviour, predicting the human actions and optimally planning the robotic ones.

AbstractBatch runs corresponding to the same recipe usually have different duration. The data collected by the sensors that equip batch production lines reflects this fact: time series with different lengths and unsynchronized events. Dynamic Time Warping (DTW) is an algorithm successfully used, in batch monitoring too, to synchronize and map to a standard time axis two series, an action called alignment. The online alignment of running batches, although interesting, gives no information on the remaining time frame of the batch, such as its total runtime, or time-to-end. We notice that this problem is similar to the one addressed by Survival Analysis (SA), a statistical technique of standard use in clinical studies to model time-to-event data. Machine Learning (ML) algorithms adapted to survival data exist, with increased predictive performance with respect to classical formulations. We apply a SA-ML-based system to the problem of predicting the time-to-end of a running batch, and show a new application of DTW. The information returned by openended DTW can be used to select relevant data samples for the SA-ML system, without negatively affecting the predictive performance and decreasing the computational cost with respect to the same SA-ML system that uses all the data available. We tested the system on a real-world dataset coming from a chemical plant.

How do rituals differ in an em world? Today, we use rituals such as graduations, marriages, retirement parties, and funerals to jointly and overtly affirm community values at key social transitions. However, if we use a broader sense of the term “ritual,” most social interactions and many apparently non-social processes are also rituals, wherein emotional energy becomes amplified as participants achieve a common focus of attention and act in ways that are finely synchronized and coordinated with each other ( Collins 2004 ). during rituals, synchronized feelings and body movements of people who are adjacent to one other become especially potent. Such group synchronization shows participants that they feel similarly to others in the group, and know each other well. people, things, and beliefs that are the mutual focus of attention in such rituals acquire added importance and emotional energy, and become able to increase the passion of subsequent rituals. The emotional energy that comes from a common focus of attention on synchronized actions has long influenced the frequency and structure of many forms of synchronized human activities, in dances, plays, movies, concerts, lectures, protests, freeways, business meetings, group recitations in schools, consumption of advertised products, and group songs that coordinate work in hunting, farming, sailing, armies, and factories. We expect ems to continue to show this tendency to prefer social situations where vivid awareness of finely synchronized actions can assure them of shared capacities and values. For example, similar to people today we expect ems to say hello and goodbye as they join and leave meetings, and to find reasons for frequent face-to-face meetings at work. Some examples of common overt rituals today are when the police stop a driver, when a waiter takes an order, when two sports teams battle in front of a crowd, and when an audience watches a movie together. In the industrial era, we have a substantially lower rate of such rituals than did our forager and farmer ancestors. For our ancestors, in contrast, it was more like having Christmas or Thanksgiving happen several times a month, with many smaller ceremonies happening several times a day (Collins 2004).

Full textAbstract:
The basal ganglia circuits have a central role in reward-based action learning, goal-directed behaviors; and habit formation. These processes largely depend on dopamine signals in the striatum, which controls the activity of the other components of the basal ganglia circuits, including the globus pallidus, substantia nigra, and subthalamic nucleus. Reward signals trigger a dopamine peak in the striatum, which promotes selection of a rewarding action and prevents initiation of competing actions. Dopamine also prevents abnormal synchronized oscillatory activity in the basal ganglia circuits. Loss of dopaminergic signaling triggers changes that underlie the motor manifestations of Parkinson disease (PD), including akinesia and levodopa-induced dyskinesia. Imbalance between dopaminergic and cholinergic signaling in the striatum underlies hyperkinetic movement disorders.

Multitudes of studies support that musical interventions in people with dementia positively affect various domains of their well-being—emotional, cognitive, and behavioral—and also reduce the distress of caregivers. However, the mechanisms underlying these effects remain unclear. This chapter proposes that rhythmic entrainment induced by listening to music, including movements synchronized with musical rhythms, might contribute to the efficacy of music-based interventions for people living with dementia. After reviewing the influence of rhythmic entrainment on motor, cognition, emotion, and social functioning, evidence obtained in dementia research is provided to support this hypothesis. Actions aligned to rhythmic sounds can be modulated by the presence of a partner, and more generally by the social environment, suggesting a link between synchronization to musical rhythm and interpersonal coordination. Finally, a method to measure rhythmic entrainment in people with dementia is presented for use in future researches to increase the intervention efficacy in pathological aging.

Full textAbstract:
Software agents controlling production devices must maintain an up-to-date view of the physical world state in order to efficiently reason and plan their actions. Especially in a factory automation system, the world state undergoes rapid evolution. To enable accurate decision-making, the world view must constantly be synchronized with the changes. This paper discusses two approaches to updating the world view based on event notifications sent by web services representing production devices in a manufacturing system. One approach requires that a set of update rules is separately specified, whereas the other involves automatically deriving the update rules from the semantic web service descriptions. While this paper specifically focuses on the factory automation domain, both of the approaches presented are applicable to other domains as well. The main assumptions are that the domain is composed of world-altering web services, which provide adequate service interfaces to detect changes in their state, and that all relevant changes in the overall domain state can be directly derived from the service state changes.

The first of the book’s four empirical chapters use the survey data to examine three issues empirically: first, we show that activists rely on a specific understanding of common good and politics that departs from that held by the general population. Second, we consider how their inclusion in a specific commitment community provides them with a particular understanding of common good and politics. Activists of a specific commitment community hence see both common good and politics through particular cognitive lenses. Third, we show that activists who evolve in the same commitment site but are members of different organizations, as well as active and passive members involved in the same organization, rely on similar views about common good and politics. From these primary analyses, we demonstrate that activists rely on socially shared meanings that are distinct from one commitment community to another. Their minds are synchronized with that of their peers and enable them to perform and sustain joint action.

Do activists rely on synchronized minds to perform joint action? What notions of democratic cultures do they hold? And what role does the mind play in participation and the sustainment of commitment? Chapter 1 introduces the reader to the central argument of the book, namely, that the mind matters to the performance of joint action, and explains why it is crucial that we dedicate more attention to this topic. The chapter further sketches the main theoretical proposal and presents the three central cognitive dimensions: activists’ relation to common good, politics, and political citizenship. The chapter’s second half explicates the comparative research design which relates the moral voicing to the Christian aid and the radical workers’ rights community. Finally, we combine survey and interview data with an innovative mixed-methods design to study the minds of activists and answer the central research questions.

This chapter considers the evolution of dance, which provides a wonderful case study with which to illustrate how human culture evolves. It shows that cultural evolution is a melting pot, with innovation often the product of borrowing from other domains, such that cultural lineages come together as well as diverge. This can be seen in the richly cross-fertilizing coevolution of dance, music, fashion, art, and technology, whose histories are intimately entwined. In the case of dance, evolutionary insights explain how humans are capable of moving in time to music; how we are able to synchronize our actions with others or move in a complementary way; how we can learn long, complex sequences of movements; why it is that we have such precise control of our limbs; why we want to dance what others are dancing; and why both participating in dancing and watching dance is fun. Armed with this knowledge, we can make better sense of why dance possesses some of the properties that it does, and why dances changed in the manner they did. As it is for dance, so it is for sculpture, acting, music, computer games, or just about any aspect of culture.

Vehicle merging on highways has always been an important aspect, which directly affects the capacity of the highway. Under critical traffic conditions, the merging of main road traffic and on-ramp traffic is known to trigger speed breakdown and congestion. Additionally, merging is one of the most stressful tasks for the driver, since it requires a synchronized set of observations and actions. Consequently, drivers often perform merging maneuvers with low efficiency. Emerging vehicle technologies, such as cooperative adaptive cruise control and/or merging-assistance systems, are expected to enable the so-called “cooperative merging”. The purpose of this work is to propose a cooperative merging system and evaluate its performance and its impact on highway capacity. The modeling and simulation of the proposed methodology is performed within the framework of a microscopic traffic simulator. The proposed model allows for the vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication, which enables the effective handling of the available gaps between vehicles. Different cases are examined through simulations, in order to assess the impact of the system on traffic flow, under various traffic conditions. Useful conclusions are derived from the simulation results, which can form the basis for more complex merging algorithms and/or strategies that adapt to traffic conditions.

Abstract The Northeast Passage in the Arctic between Europe and Asia offers a significantly shorter voyage compared to the Southern route through the Suez Canal. In 2017, the EU research project “Safe maritime operations under extreme conditions: the Arctic case (SEDNA)” was established to perform a comprehensive analysis of Arctic transit shipping and to promote technical solutions for this purpose. This paper is based on the deliverables of the SEDNA project. A voyage planning tool (VPT) for Arctic applications was developed to plan the optimal route regarding ship’s fuel consumption and safety. One of the most advanced metocean and ice forecast model is utilized to provide comprehensive environmental conditions that are synchronized and will be updated frequently during the voyage. The ship energy system model takes into account the various environmental variables as well as ship’s operational conditions to compute the ship performance in both open and ice infested waters. For Arctic operations, specific ice resistance models are implemented in the VPT, and a user has the options of either relying on icebreaker assistance or going for unassisted navigation in part of the entire Arctic passage. Case study voyages of different ship types, route options, staring time, home/destination ports are simulated to demonstrate how various optimal routes are planned and how the transit time and fuel consumption vary. This information is considered being crucial for ship owners for planning their voyages in advance. The continuously updated voyage information from the VPT is particularly helpful for the ship crew if there are specific ship operations and risk mitigation actions that need to be taken care of during the voyage. In addition, this study underlines that a safe and fuel-efficient Arctic passage requires viable voyage planning tools that combine reliable ship performance with weather and ice forecasts.

Full textAbstract:
By using a newly-developed experimental technique that is enabled by a polymer-based microfluidic device for detecting distributed normal loads, a preliminary study is presented on the synchronized heterogeneous indentation and stress relaxation behavior of articular cartilage upon macroscopic compression. In a measurement, a rigid cylinder probe is employed to exert macroscopic indentation or step input to a cartilage sample on the device. Consequently, the synchronized heterogeneous viscoelastic behavior of the sample translates to distributed normal loads acting on the device and is captured by the device. While the macroscopic load acting on a sample is recorded by a load cell, the deflections of a sample along its length are captured by the device. Thus, the measured results essentially are the load-deflection relations of a sample along its length. Full-thickness lapine and bovine articular cartilage samples are prepared and measured. A thorough data analysis is implemented on the recorded data for extracting their instant and relaxed indentation modulus, as well as Young’s relaxation modulus.

Full textAbstract:
Manual transmissions for passenger cars and trucks are equipped with synchronizer mechanisms. A synchronizer mechanism as a key component of a transmission system must be able to prevent transmission gears from shocking, reduce the noise and it has a great impact on driving comfort and transmission efficiency. Gear shifting improvement with respect to smooth, quick and energy efficient synchronizer’s performance is still an important issue for automotive industry. A synchronization process comprises several phases within which presynchronization, main synchronization, pre-engagement and engagement phases can be recognized. Aiming an understanding of internal dynamics and existing possibilities for optimization of synchronization processes in transmission systems during the main synchronization phase an engineering model of a generic synchronizer mechanism is proposed. The synchronizer mechanism is modeled by a contacting triple-body system consisting of the selector sleeve, the blocker ring and the gearwheel. The algorithm has developed to solve the direct dynamics synchronization problem for the generic synchronizer mechanism. By using the developed algorithm the rotational motion of the contacting triple-body system and the synchronizing torques between contacting interfaces are determined for given vehicle resistance torque, the drag torque, and the control torque applied to the selector sleeve that all together satisfy the equations of motion and guarantee synchronization of the rotational speeds of the sleeve, the blocker ring and the gearwheel for the final time. It is shown that the solution to the direct dynamics synchronization problem for the generic synchronizer mechanism is not unique and it allows formulation different optimization problems. Mathematical statement of multi-objective Pareto optimal control problem for synchronizer mechanism is given. Within the proposed model of the generic synchronizer mechanism the time-comfort Pareto optimal control problem is considered. Assuming that the resistance torque on the synchronizer owing to the vehicle inertia, the drag torque, and the synchronizing torques at the contacting interfaces are substantially constant during the main phase of a synchronization process, the solution to the time-comfort Pareto optimal control problem has been obtained. It was shown that there exist the external control torque (or shift force) applied to the selector sleeve such that the synchronization of rotational speeds of the sleeve, the blocker ring and the gearwheel is guaranteed and the synchronization process is optimal both with respect to minimal possible synchronization time as well as lowest possible inertial load acting on the synchronizer mechanism. Analysis of the obtained Pareto solution is presented.

Full textAbstract:
The paper presents a method to optimise the synchroniser of a road vehicle gearbox in order to improve shiftability and driver comfort. A multi-body physical model of the synchroniser has been developed and validated experimentally. The optimisation method is based on a Multi-objective Programming approach, and it allows to tune the thirty-two parameters of the synchroniser in order to achieve the desired dynamic behaviour of the system during a reference shift action, defined by seven performance indices. A Global Approximation procedure has been followed to solve numerically the optimisation problem. A special study has been performed and implemented in order to explore all of the feasible design solutions within the design variables domain. A global sensitivity method has been applied in order to analyse the relationships among the thirty-two design variables and the seven performance indices. Pareto-optimal design solutions have been computed in a very short time. These Pareto-optimal solutions have been checked for robustness by applying the minimum sensitivity method. The optimisation method has been applied with successful results. A number of optimised synchronisers have been defined, all of them featuring relevant improvements in the dynamic behaviour (shiftability) with respect to the reference synchroniser, aleady effective and under production.

Abstract Robot skills provide a way to model and reuse sensor and robot technologies in effective ways. Skills can integrate and synchronize robot actions and sensor data in a consistent way and provide a framework for configurable robot systems, enabling quick setups of applications. Skills and skill modeling can be used not only for representing the composition of sensor based robot tasks, but also for programming on-line such tasks. In this paper we will introduce a skill based approach for representing on-line programming of skill based tasks. We will also give a practical example for modelling and implementing on-line programming of a handling skill relying on use of object localization sensors.

Full textAbstract:
This paper presents a theoretical–experimental pressure analysis of a hydraulic press brake with synchronized cylinders. In this machine, the motion of each cylinder is controlled by independent variable-speed electrical motors. This design has many benefits over traditional solutions using hydraulic proportional valves, such as higher energetic efficiency, nonrequirement of a heat exchanger, lower oil-cleanliness requirement, and reduced audible noise. However, a critical characteristic of the press brake is the use of double acting cylinders with large rods controlled by a pump in a closed circuit. In the studied system a cap end area roughly eleven times greater than the rod end area is used. Furthermore, the synchronized hydraulic press brake operates in six stages with particular characteristics implying in different flow rate demands and pressure behaviors. Based on experimental results, the pressures in specific parts of the circuit are analyzed and critical operational conditions are identified. A simulation model using Hopsan is validated and used to propose a hydraulic circuit modification. The proposed solution eliminates the tendency for pump cavitation and pressure surges that occur during the press break operational cycle.

Full textAbstract:
In the paper, a 2D numerical model is established to simulate the hydrodynamic forces on a submarine piggyback pipeline under regular wave action. The two-dimensional Reynolds-averaged Navier-Stokes equations with a κ-ω turbulence model closure are solved by using a three-step Taylor-Galerkin finite element method (FEM). A Computational Lagrangian-Eulerian Advection Remap Volume of Fluid (CLEAR-VOF) method is employed to simulate free surface problems, which is inherently compatible with unstructured meshes and finite element method. The numerical results of in-line force and lift (transverse) force on the piggyback pipeline for e/D = G/D = 0.25 and KC = 25.1 are compared with physical model test results, which are conducted in a marine environmental flume in the State Key Laboratory of Coastal and Offshore Engineering, Dalian University of Technology, China. It is indicated that the numerical results coincide with the experimental results and that the numerical model can be used to predict the hydrodynamic forces on the piggyback pipeline under wave action. Based on the numerical model, the surface pressure distribution and the motion of vortices around the piggyback pipeline for e/D = G/D = 0.25, KC = 25.1 are investigated, and a characteristic vortex pattern around the piggyback pipeline denoted “anti-phase-synchronized” pattern is recognized.

This paper addresses design of a motion controller for a teen sized biped robot, Archie. The main goal is to develop a motion controller for a cost oriented robot to assist human in daily life. The proposed real-time controller enables each joint individually to receive reference speed and position to provide a smooth motion. In this scheme, action commands are transmitted via Control Area Network (CAN) bus from a PC to robot. Aim of using such a communicator is to provide error process mechanism with a message priority concept. The main advantage of this method is to synchronize the motion of all joints necessary for biped walking motion. Finally test and implementation results are presented to demonstrate the good performance.
