A new robust control strategy for axial flux permanent magnet motor applied on legged lunar robots

Legged robots have the advantage of strong terrain adaptability in lunar exploration. A new robust controller is designed for axial flux permanent magnet motors applied on the legged lunar robots to diminish the disturbance from uncertainty and external circumstance. The theoretical verification is carried out through Lyapunov stability theory. The numerical simulation and real-time experiment are carried out to access the stability and dynamic property of the systems adopting the proposed controller. The results are compared with the traditional control strategies to demonstrate the advantages of the proposed controller. The new robust controller contributes to the dynamic stability of legged lunar robots and is also appropriate for the similar mechanical systems.

COVID 19: Compliance, Deviances, Social Control and Contagion Risks during the Lockdown. The Results of a Research in Two EU Countries (Italy and Romania)

The pandemic spread caused by the Covid 19 virus and the consequent risk of contagion has recently forced most national governments to adopt drastic measures of social control and containment, such as social distancing, which has led to a significant change in the lives and habits of citizens, which in turn pushed people to adapt to a changed external circumstance. This adaptation, which translates sociologically and substantially into a request for compliance with the prescriptions, had in many cases captured oppositional reactions through individual and group deviant behaviors, which, in addition to breaking the rules of a community, have contributed to the violation of that general principle of “mutual altruism” that should characterize modern societies and increase the viral contagion. The conducted research has explored the risks of contagion from Covid 19 regarding compliant or deviant conducts of behavior with reference to the lockdown requirements in the first half of 2020.

Hippocampal cells integrate past memory and present perception for the future

The ability to use stored information in a highly flexible manner is a defining feature of the declarative memory system. However, the neuronal mechanisms underlying this flexibility are poorly understood. To address this question, we recorded single-unit activity from the hippocampus of 2 nonhuman primates performing a newly devised task requiring the monkeys to retrieve long-term item-location association memory and then use it flexibly in different circumstances. We found that hippocampal neurons signaled both mnemonic information representing the retrieved location and perceptual information representing the external circumstance. The 2 signals were combined at a single-neuron level to construct goal-directed information by 3 sequentially occurring neuronal operations (e.g., convergence, transference, and targeting) in the hippocampus. Thus, flexible use of knowledge may be supported by the hippocampal constructive process linking memory and perception, which may fit the mnemonic information into the current situation to present manageable information for a subsequent action.

A Modified Fractional Differential Love Model

A modified system of nonlinear fractional-order differential equations become used to classify humans of various personalities and different Impact Factors of Memory (IFM); with unique set of model parameters. The model was used to interpret and predict the functions of the union of various people with external circumstance(s) and adapted to neighborhood environment in which the statistics collections were achieved to analyze numerous measures affecting marriages, unique challenges in marriage and associated occasions were investigated through the use of questionnaire. Data had been analyzed and the outcomes have been carried out as parameters to validate the model. Adams Predictor-Corrector Method was used to test the chaoticity of the system and it was confirmed via numerical simulations.Numerical simulation outcomes had been presented to reveal the effectiveness of the model and the accuracy of the statements established. The mathematical information implied by the model unveil an underlying mechanism which can give an explanation for couple disruption in relationships that were initially deliberated to remain all the time. Despite the terrible aspects of relationships, some human beings were still satisfied in their intimate members of the family. The study was addressed on a field survey (use of questionnaires) and with the aid of interrogating the members one on one. A feasible path for future work is the choice to attain balance through modelling and to validate the results with the aid of numerical simulations.

The Structure of Genji’s Career

The hero of The Tale of Genji is famous or infamous above all as a lover and a seductive master of the courtly arts. The political aspects of his career are not as well recognized, perhaps because they are often difficult to distinguish from his love interests. One goal of this essay is to disentangle in Genji’s case political or personal advantage from erotic enterprise. A second goal is to show that Genji’s overt career follows a political (for want of a better word) trajectory that gives his story an underlying form distinct from simple acknowledgment of passing time. The main issues are the imperial succession, acquisition of decisive influence at court, and hierarchically advantageous marriage. Genji’s trajectory follows the rise of a man who comes against the odds to dominate his world, then overreaches himself and loses all that he holds most dear. Having been forced by external circumstance to favor his lackluster first son (Suzaku) publicly, the Kiritsubo Emperor does all he can to favor his brilliant second son (Genji) privately. Feeling cheated of the honor to which his gifts and his father’s favor should have destined him, Genji maneuvers successfully to overcome those who forced him into this position. Out of pride he then takes a gratuitous step that estranges him from his beloved Murasaki and, by the way, crushes his unfortunate brother. When last seen, he is only the shell of a once great man.

Learning from praxis

Purpose – This paper uses a number of current examples from a variety of industries both regional and global, to explore the relationship between business longevity, environment, and adaptiveness to argue that only adaptive responses contingent on a proper classification of external circumstance will result in productive efficacy for the business. The paper aims to discuss these issues. Design/methodology/approach – There is compelling evidence that businesses have limited life spans. Management and economic theories of creative destruction, argue that this is salutary for markets and economies. Yet as a counterpoint there are significant benefits to business longevity. Such longevity, however, is predicated on the business's dimensionalised understanding of its task and contextual environment and its deployment of an adaptive response contingent on such understanding. Findings – It is mandatory in prevailing times that adaptive responses ensure that the overall business has external fit and alignment with its environment and internal congruence and consistency between organisational subsystems and their internal subenvironments. Originality/value – The calculus of limited and unpredictable business life spans is justified by theories of creative destruction and hypercompetition. Yet there are intrinsic and extrinsic advantages to business longevity. A causative flow is proffered that predicates business longevity on its ability to; first, classify its prevailing environment, and thereafter deploy contingent adaptive responses for productive efficacy.

British Parliamentary Party Alignment and the Indian Issue, 1857–1858

During the unusually hot summer of 1857 English society was shocked and outraged by reports of atrocity and mass murder. News of the outbreak of the Indian Mutiny reached London on June 26, 1857 and, during the succeeding months, tales of massacre and torture followed. Polite Victorian society was incensed. This article examines Parliament's response to this crisis. It reveals that there exists no simple relation between events occurring outside Westminster and the response within. Parliamentary perception passes through the medium of public rhetoric, established policy, party circumstance, and the private concerns of prominent personalities. This creates less a refractive distortion of events than a new aspect to their understanding. Issues such as India acquired significance within a continuing context of parliamentary circumstance long preceding the immediate cause of substantive concern. This article, then, is not about India as such, but about the particular form the Indian question assumed within Westminster. This is a significant concern in itself because of the insight preoccupation with India provided into the tensions, antagonisms, aspirations, and hopes shaping party alignment during the mid-nineteenth century.A further aspect of this translation of external circumstance into parliamentary perception is that an issue only became the occasion of crisis when it was portrayed as critical. Once again, there existed no simple relation between external events and the response within Westminster. Popular moral outrage over native atrocities became a political crisis over administrative reform. This particular parliamentary response was neither necessary nor inevitable. The recognition of crisis and the particular crisis perceived are themselves historical events that require explanation.

Melancholia and Barbiturates: A Controlled Eeg, Body and Eye Movement Study of Sleep

Insomnia is widely accepted as a leading feature of that illness designated by the number 301.1 in the International Classification of Diseases. The name given varies—“endogenous depression”, “manic-depressive psychosis/depressive type”, “melancholia” or “depressive illness”. The present generation of laymen (not to say some psychiatrists) use the word “depression” so freely in order to describe an unpleasant, unhappy mood, whether lasting or transient, that one may prefer the term melancholia, or at least “depressive illness”, to signify that condition which justifies the number 301.1. The adjective “endogenous” implies for many that environmental stress plays little or no part in the onset of the illness; we cannot accept that this is always so. The term “reactive” is used in several ways, generally to indicate that the state of unhappiness arises out of some external circumstance and that it would end when circumstances improved or the individual accepted the realities of practical life. The patients used in the present study were suffering from an illness of a kind which we believe may sometimes develop in the absence of severe environmental stress, while in others it may be clearly provoked by circumstances, but the illness, as it develops, may take on a form which becomes largely independent of the environmental circumstances and may continue even when the provoking factors are past; it has become an autonomous melancholia. It will be apparent that by autonomous melancholia we mean an illness shown by clinical experience to respond especially well to electroplexy.

Authenticity, Metaphysics, and Moral Responsibility

MR. A is a liar. He repeatedly tells untruths, sometimes with malicious intent, sometimes for the purpose of dramatizing himself. Although he is perfectly aware of telling these untruths, he none the less ardently proclaims to himself and to others his complete honesty. In doing so it is no part of his intention to deny or to overlook the facts of the case. On the contrary he confesses his misdeeds with an embarrassing frankness. Mr. A's intention is to explain and to excuse these misdeeds. He says that each of his lies has been required by some accidental or unusual external circumstance, that his true inner self is in no way responsible for them and in no way affected by them. By nature, in his essence, he is absolutely honest.
