SUMMARYSeries elastic actuators have beneficial properties for some robot applications. Several recent implementations contain alternative placements of the compliant element to improve instrumentation design. We use a class 1 versus class 2 lever model and energy-port methods to demonstrate in this paper that these alternative placements should still be classified as series elastic actuators. We also note that the compliance of proximal series elastic actuators is reflected by an augmented gear ratio dependent on the nominal gear ratio, which is significant for small gear ratios and approaches unity for large gear ratios. This reflected compliance is shown to differ depending on the sign of the gear ratio. We demonstrate that although the reflected compliance is only marginally influenced by the magnitude of the gear ratio, there are several notable differences, particularly for small gear ratios.

The prime source of vibration and noise in a gear system is originated from transmission error between the meshing gears. In this paper, the dynamic modeling method and response of a spur gear pair for the efficient system simulation are investigated by using a detailed contact analysis at each time step. Input values such as time-varying mesh stiffness and static transmission error excitation are not required in this investigation because mesh forces are obtained by contact analysis directly. The efficient contact search kinematics and algorithms in the context of the compliant contact model are developed to detect the interactions between teeth surfaces. In this investigation the compliant force model based on the Herzian law is employed using Coulomb friction force model, and dynamic transmission error (DTE) and mesh frequency values of contacting gear system are also illustrated.

Background: Although the increased occupational exposures among career firefighters are well documented, there are gaps in research related to exposures among volunteer firefighters. This study was completed in a state where the majority of firefighters are volunteers. We aimed to examine if differences existed in career versus volunteer firefighters’ behaviors related to the retirement, cleaning, and storage of turnout gear which may increase occupational exposures. Methods: A cross-sectional survey was administered to a convenience sample of 300 firefighters during a training event for both volunteer and career firefighters from one fire district in Kentucky. We measured factors that may affect behaviors related to retirement, cleaning, and storage of turnout gear, such as age of turnout gear at retirement, frequency of cleaning, and location of storage. Results: Two hundred and seventy-five firefighters out of 300 invited participants completed the survey, for a response rate of 92%. The majority of the participants were compliant with National Fire Protection Association Standards with most reporting cleaning their gear as needed, storing gear at the fire station, and retiring gear within 10 years of the manufactured date. Most of the participants (88%) were concerned about job-related exposures and felt susceptible to diseases like cancer and respiratory illness. The structural issues of cost and accessibility were identified as the primary barriers to the proper retirement and cleaning of turnout gear, especially among volunteer firefighters. Conclusions/Application to Practice: Most participants retired, cleaned, and stored turnout as recommended. The majority of participants were concerned with job-related exposures. The structural issues of cost and accessibility were identified as the primary barriers to the proper retirement and cleaning of turnout gear, especially among volunteer firefighters. By identifying differences, tailored trainings could be aimed at volunteer firefighters to help reduce their exposures.

A water muffler is used for the noise control of a hydraulic pipeline with an external gear pump. An experimental system is established to investigate the acoustic performance of the water muffler, in which the gear pump is utilized as the sound source and power supply. Comparisons between the experimental results of the reference tube, rubber tube, and water mufflers with different inner structures have been made. Numerical simulations on the rubber tube and different water mufflers with various inner structures have been conducted. Simulation results have been compared with the experimental results. These comparison results show that the rubber tube with a compliant wall substantially contributes to the reduction of the noise generated by the gear pump, especially at the high frequency band and relatively low rotate speed of the gear pump. The water muffler results in the enhancement of the noise reduction effect on the rubber tube. With the speed of the gear pump increasing from 1172 r/min to 2344 r/min, the effect of the noise reduction becomes much weaker, since the flow-induced noise gets more intensified. For the rubber tube, in particular, the sound pressure level gets close to that of the reference tube at the speed of 2344 r/min. Moreover, it has been proven by another important experimental result that the length of the inner structure can play a critical role to the flow noise generation.

The pervasive use of AI today caused an urgent need for human-compliant AI approaches and solutions that can explain their behavior and decisions in human-understandable terms, especially in critical domains, so as to enforce trustworthiness and support accountability. The symbolic/logic approach to AI supports this need because it aims at reproducing human reasoning mechanisms. While much research has been carried out on single inference strategies, an overall approach to combine them is still missing. This paper claims the need for a new overall approach that merges all the single strategies, named MultiStrategy Reasoning. Based on an analysis of research on automated inference in AI, it selects a suitable setting for this approach, reviews the most promising approaches proposed for single inference strategies, and proposes a possible combination of deduction, abduction, abstraction, induction, argumentation, uncertainty and analogy. It also introduces the GEAR (General Engine for Automated Reasoning) inference engine, that has been developed to implement this vision.

Abstract The objective of this study was to evaluate satisfaction, usability and compliance using the Real-Time, Online Assessment and Mobility Monitor (ROAMM) application designed for smartwatches. Twenty-eight older adults with knee osteoarthritis (66-88 years old) wore a Samsung Gear S3 smartwatch with ROAMM. While wearing the watch for 13.16 (±2.94) days, participants gave ecological momentary assessments (EMA) of pain intensity, mood and fatigue at random times in the morning, afternoon and evening. EMA compliance rate was 82.5%. Satisfaction ratings were high with 73% reporting being satisfied with the function, 78% reported being satisfied with the comfort and 73% reported as likely to use ROAMM on a daily basis for a one-year research study. Participants reported to reduce watch size and weight, style and increase battery life. Older adults were compliant to ecological assessment of their symptoms and reported positive usability and satisfaction of wearing a smartwatch and ROAMM app.

Inspired by talon of a predator bird, this paper presents a quadrotor with two 2- Degree of Freedoms (DOFs) compliant manipulators which could mimic bird perching and grasping. The symmetric configuration of the manipulators causes minimum shift in center of gravity and a minimum disturbance to the angular momentum of the platform during grasping and perching maneuvers. Thus, the dynamics of the manipulator is independent to that of the platform. Moreover, a compliant end-effector is introduced to decouple the dynamics of the unmanned aerial vehicles from the force interaction with the environment or target objects. Therefore, aerial manipulation problem is significantly simplified due to the minimum amount of disturbance among components. In addition, the manipulators could function as the landing gear, which allows larger work envelope, weight saving and less landing impact. It also has the potential to achieve a bird-like “perch and watch” to increase the endurance of unmanned aerial vehicles in missions that involve extended endurance.

Agentes públicos de maneira geral estão percebendo a necessidade de inovar e aperfeiçoar os serviços públicos. Outro não poderia ser o caminho, pois o Estado, a quem os agentes públicos prestam seus serviços, intervém direta e indiretamente na ordem econômica por autorização da Constituição da República Federativa do Brasil, de 5 de outubro de 1988, nos termos do art. 173 fincado no Título VII, que trata da Ordem Econômica e Financeira. Das formas de intervenção indireta estatal apontadas pelos estudiosos, o planejamento é decerto aquela que mais se relaciona ao bom desempenho do setor público. Com a escassez de recursos materiais, humanos e financeiros, planejar se tornou uma ação vital para a administração pública. Não por acaso, a Constituição Federal estabelece em seu art. 174 que o planejamento é determinante para o setor público, o que destaca a relevância do planejamento estratégico e o impacto dessa atividade nas Instituições. No atual cenário de crise econômica e restrições a recursos financeiros, preconiza-se a necessidade e a exigência de um Estado mais eficiente no manejo dos gastos públicos para o atendimento mais eficaz das demandas da sociedade. Neste sentido, importante avanço foi incorporado ao nosso ordenamento pela nova Lei Geral de Licitações e Contratos, a Lei nº 14.133, de 1º de abril de 2021, ao positivar os novos princípios do planejamento, da transparência, da eficácia, da segregação de funções, da motivação, da segurança jurídica, da razoabilidade, da competitividade, da proporcionalidade, da celeridade, da economicidade e do desenvolvimento nacional sustentável. Merece destaque a sustentabilidade, uma vez que na Lei de Licitações (Lei 8.666/93) o tema era superficialmente abordado, ficando a cargo da discricionariedade administrativa. Entretanto, com o advento da Nova Lei de Licitações e Contratos (Lei nº 14.133/2021), o desenvolvimento nacional sustentável assume o duplo papel de princípio e de objetivo da licitação. Percebe-se que o novel diploma caminha à inovação e a modernização da já defasada legislação em vigor, possibilitando a unificação de regras, além de gerar uma maior agilidade nas licitações e execução dos contratos administrativos. É aqui que as contratações públicas assumem relevância no desenvolvimento econômico dos entes políticos, seja na esfera federal, estadual ou municipal. Seu executor, o gestor público, é personagem principal da aquisição proba, eficaz e transparente, em atuação sempre pautada pela legalidade e inovação com vistas à proposta mais vantajosa em contrapartida à promoção do desenvolvimento sustentável. Em consequência, oplanejamento torna-se rotina obrigatória e fundamental a qualquer instituição não apenas enquanto instrumento de gerenciamento orçamentário, mas também como ferramenta para o aumento da oferta e da qualidade dos serviços públicos disponíveis aos cidadãos, devendo ser incorporado a toda atividade administrativa. Esta Cartilha tem por objetivo informar aos gestores públicos, de maneira clara e precisa, sobre a chamada "fase interna da licitação", que pela nova Lei Geral atende por “fase preparatória”. É um estímulo à incorporação de valores e do necessário planejamento nas aquisições de bens e serviços para atendimento às necessidades do Poder Executivo Municipal de Camaragibe, em face de sua extrema relevância no cotidiano dos gestores e seu impacto direto na realização de qualquer despesa pública. A formulação deste produto partiu da necessidade de reestruturação funcional do Ente Público, vítima de quebra da continuidade nos procedimentos administrativos em decorrência de acontecimentos políticos que lhe modificaram a conformação do Poder. Com a vigência da nova Lei de Licitações e Contratos (Lei nº 14.133/2021), emergiu com mais vigor a necessidade de organização dos procedimentos licitatórios, fundamentais para a transparência da gestão a possibilitar o inescapável controle externo. Mais que reestruturar o fluxo dos processos utilizados em sua atividade material, foi preciso inovar a prática administrativa com o uso oportuno do período de transição do novo diploma (que possui lapso temporal de dois anos) para compatibilizar a utilização da legislação anterior, que ainda produz efeitos jurídicos, com a nova Lei. Para isso, foram empreendidos estudos para atualizar os procedimentos da Lei nº 8.666/1993, da Lei nº 10.520/2002 e da Lei nº 12.462/2011, com vistas à implantação das mudanças que deverão ser necessariamente aplicadas a partir de 1º de abril de 2023, com a revogação obrigatória das normas anteriores e o estabelecimento pleno e definitivo da Lei nº 14.133/2021. Assim, esta Cartilha destina-se a consagrar a boa prática administrativa, estruturando procedimentos que induzem a uma gestão integra, competente, eficaz e transparente, com foco na inovação e nas modernas ferramentas de gestão que traduzem o compliance enquanto instrumento da prevenção de riscos no âmbito da atividade administrativa pública. Este material orientativo foi elaborado pelos alunos do Mestrado em Gestão do Desenvolvimento Local Sustentável - FCAP/UPE, com a participação da Controladoria-Geral do Município de Camaragibe e da Secretaria Municipal de Administração, na expectativa de que seja utilizado pelos gestores públicos e demais agentes da administração direta e indireta do Ente como instrumento de prevenção às irregularidades, aos desvios e ao desperdício de recursos públicos.

<i>Abstract</i>.—Overexploitation of wild sturgeon (Acipenseridae) species worldwide for caviar has led to a shift in harvest to Paddlefish (Polyodontidae: <i>Polyodon spathula</i>), another Acipenseriform species and a state-managed fish still harvested commercially in eight states within the United States. State game and fish agencies with commercial fisheries are increasingly being pressured to open or extend commercial Paddlefish fisheries under their respective jurisdictions. In addition to the increased needs for a multi-state management framework among states, new demands on the Paddlefish within states and its high vulnerability to overharvest require more proactive, innovative, and restrictive management approaches than the frequently liberal regulations of the past. This paper describes proactive management strategies implemented by state fisheries agencies in Alabama and Mississippi for the long-term conservation of their Paddlefish fisheries. The management actions implemented fall into three broad areas: (1) fishing areas, seasons, and participation; (2) fishing and harvest restrictions; and (3) licensing fees, reporting, and training. Actions taken under (1) included defining Paddlefish management areas, establishing specific harvest seasons and daily harvest times, and limiting the number of harvesters. Actions under (2) included enacting length limits and female-only harvest (Alabama), implementing harvest (carcass) tags to track fish and roe, and establishing gear restrictions to reduce unintended Paddlefish mortality. Actions under (3) included establishing rational permit requirements and fees, establishing specific harvest reporting requirements, and providing informational training to aid in angler compliance. Although there are many similarities in the approaches taken, each state has tailored its regulations to its political and biological situation. Alabama and Mississippi will be evaluating the effectiveness of their approaches and needed adaptations will be made to ensure long-term sustainability of the Paddlefish.

This study analytically investigates the vibration of high-speed, compliant gear pairs using a model consisting of coupled, spinning, elastic rings. The gears are elastically coupled by a space-fixed, discrete stiffness element that represents the contacting gear teeth. Hamilton’s principle is used to derive the nonlinear governing equations of motion and boundary conditions. These equations are linearized for small vibrations about the steady equilibrium due to rotation. The equations are cast in operator form, which exemplifies their gyroscopic system structure. The eigenvalue problem is discretized using Galerkin’s method. The natural frequencies and vibration modes for an example aerospace gear pair are numerically calculated for a wide-range of rotation speeds. The system coupling leads to multiple eigenvalue veering regions as the gear rotation speed varies. Highly coupled vibration modes that have meaningful deflection in the discrete mesh stiffness occur within a set frequency band. The vibration modes within this band have distinct nodal diameter components that evolve with rotation speed.

Abstract The current computation models for gear contact analysis and wear prediction are mostly based on finite element analysis which consumes much computation time and effort. In this work, we adopt an alternative approach for gear contact analysis using linear complementarity. This approach was successfully applied to a pair of rigid spur gears and a planetary gear train (gears are considered as rigid bodies) in our previous work. In this paper, we extend our linear complementarity model to consider local deformation caused due to contact between gear teeth in mesh. Thus obtained linear complementarity model is applied to a pair of spur gears and a planetary gear train. A linear complementarity solver computes the contact forces between meshing teeth of gears. From the contact forces, sliding wear in gear teeth is predicted. Archard’s wear model is used for the wear prediction. Using this model, the contact forces are uniquely determined for the examples considered. The results of linear complementarity and finite element model for a pair of spur gears are compared. The linear complementarity model consumes much less computation time than the finite element model.

In a novel compliant parallel mechanism, a motor and spring are arranged in a parallel fashion and are connected to a movable lever arm. The motor pushes and pulls on one attachment point and the spring stores and releases energy at a second attachment point. In a non-obvious choice, we do not attach the output link to the commonly thought of end-effector, but to the third link in the planar, parallel mechanism. The new mechanism allows the transmission ratio of the motor to be a function of the output angle and the force applied at the spring. For example, if there are no loads on the spring, the overall gear ratio is lowered, and the output speed can be increased. Conversely, if there are loads on the spring, the overall gear ratio is increased, and the output torque can be increased.

This paper examines the vibration modes of single stage helical planetary gears in three dimensions with equally spaced planets. A lumped-parameter model is formulated to obtain the equations of motion. The gears and shafts are modeled as rigid bodies with compliant bearings at arbitrary axial locations on the shafts. A translational and a tilting stiffness account for the force and moment transmission at the gear mesh interface. The modal properties generalize those of two-dimensional spur planetary gears; there are twice as many degrees of freedom and natural frequencies due to the added tilting and axial motion. All vibration modes are categorized as planet, rotational-axial, and translational-tilting modes. The modal properties are shown to hold even for configurations that are not symmetric about the gear plane, due to, for example, shaft bearings not being equidistant from the gear plane. Computational modal analysis are performed to numerically verify the findings.

Abstract This paper presents an improved design concept for a surgical robot that contributes to improved human-robot interaction and precise positioning of surgical tools. Based on a spherical wrist design, the robot incorporates new human-safe features limiting its ability to apply excessive force and uses a novel adaptation of the compliant rolling-element (CORE) joint suitable for conical rolling surfaces. The proposed safety features aim to provide novel functionality by mechanically disengaging the drive in overload conditions. This approach avoids the necessity of force sensing and control to detect and compensate for unintended device collisions. Further, proof of concept of a novel compliant rolling-element joint is presented as a low-backlash alternative to bevel gear pairs for heightened precision in angular positioning.
