Abstract:
The objective of this study was to test the feasibility of using a pair of wearable inertial measurement unit (IMU) sensors to accurately capture dynamic joint motion data during simulated occupational conditions. Eleven subjects (5 males and 6 females) performed repetitive neck, low-back, and shoulder motions simulating low- and high-difficulty occupational tasks in a laboratory setting. Kinematics for each of the 3 joints were measured via IMU sensors in addition to a “gold standard” passive marker optical motion capture system. The IMU accuracy was benchmarked relative to the optical motion capture system, and IMU sensitivity to low- and high-difficulty tasks was evaluated. The accuracy of the IMU sensors was found to be very good on average, but significant positional drift was observed in some trials. In addition, IMU measurements were shown to be sensitive to differences in task difficulty in all 3 joints (P < .05). These results demonstrate the feasibility for using wearable IMU sensors to capture kinematic exposures as potential indicators of occupational injury risk. Velocities and accelerations demonstrate the most potential for developing risk metrics since they are sensitive to task difficulty and less sensitive to drift than rotational position measurements.

Abstract:
Hand gesture recognition and hand pose estimation are two closely correlated tasks. In this paper, we propose a deep-learning based approach which jointly learns an intermediate level shared feature for these two tasks, so that the hand gesture recognition task can be benefited from the hand pose estimation task. In the training process, a semi-supervised training scheme is designed to solve the problem of lacking proper annotation. Our approach detects the foreground hand, recognizes the hand gesture, and estimates the corresponding 3D hand pose simultaneously. To evaluate the hand gesture recognition performance of the state-of-the-arts, we propose a challenging hand gesture recognition dataset collected in unconstrained environments. Experimental results show that, the gesture recognition accuracy of ours is significantly boosted by leveraging the knowledge learned from the hand pose estimation task.

Abstract:
In this paper, we present a work-flow to investigate the joint visibility between very-high-resolution SAR and optical images of urban scenes. For this task, we extend the simulation framework SimGeoI to enable a simulation of individual pixels rather than complete images. Using the extended SimGeoI simulator, we carry out a case study using a TerraSAR-X staring spotlight image and a Worldview-2 panchromatic image acquired over the city of Munich, Germany. The results of this study indicate that about 55&amp;thinsp;% of the scene are visible in both images and are thus suitable for matching and data fusion endeavours, while about 25&amp;thinsp;% of the scene are affected by either radar shadow or optical occlusion. Taking the image acquisition parameters into account, our findings can provide support regarding the definition of upper bounds for image fusion tasks, as well as help to improve acquisition planning with respect to different application goals.

Full text
Abstract:
Controlling a chain of tethered mobile robots (TMRs) can be a challenging task. This kind of system can be considered kinematically as an open-chain robotic arm where the mobile robots are considered as a revolute joint and the tether is considered as a variable length link, using a prismatic joint. Thus, the TMRs problem is decoupled into two parallel problems: the equivalent robotic manipulator control and the tether shape computation. Kinematic redundancy is exploited in order to coordinate the motion of all mobile robots forming the chain, expressing the constraints acting on the mobile robots as secondary tasks for the equivalent robotic arm. Implementation in the Gazebo simulation environment shows that the methodology is capable of controlling the chain of TMRs in cluttered environments.

Abstract:
Compared to traditional rigid robots, continuum robots have intrinsic compliance and therefore behave dexterously when performing tasks in restricted environments. Although there have been many researches on the design and application of continuum robots, a theoretical investigation of their dexterity is still lacking. In this paper, a two-joint wire-driven continuum robot is utilized to demonstrate dexterity by introducing the concept of orientability taking into account two indices, the accessible ratio and angle of the robot, when its tip reaches a certain task space inside the workspace. Based on the kinematic model, the accessible ratio and angle of the continuum robot are calculated using the Monte-Carlo method. From this, the influence of individual joint lengths on the proposed orientability indices and the optimal joint length are then investigated via an improved particle swarm optimization algorithm. Finally, the presented methods were validated through experiments showing that the use of optimal joint length can increase the accessible ratio and reduce the minimum accessible angle by more than 10° in the task space.

Abstract:
The human motor system regulates arm mechanics to produce stable postures during interactions with different physical environments. This occurs partly via involuntary mechanisms, including stretch reflexes. Previous single-joint studies demonstrated enhanced reflex sensitivity during interactions with compliant environments, suggesting reflex gain increases to enhance limb stability when that stability is not provided by the environment. This study examined whether similar changes in reflex gain are present throughout the limb following perturbations that simultaneously influence multiple joints. Furthermore, we investigated whether any observed modulation was accompanied by task-specific changes in reflex coordination across muscles, a question that cannot be addressed using single-joint perturbations. Reflexes were elicited during the maintenance of posture by perturbing the arm with a three degrees of freedom robot, configured to have isotropic stiffness of either 10 N/m (compliant) or 10 kN/m (stiff). Perturbation characteristics were matched in both environments. Reflex magnitude was quantified by the average rectified electromyogram, recorded from eight muscles crossing the elbow and shoulder. Reflex coordination was assessed using independent components analysis to compare reflex activation patterns during interactions with stiff and compliant environments. Stretch reflex sensitivity increased significantly in all muscles during interactions with the compliant environment and these changes were not due to changes in background muscle activity. However, there was no significant difference in the reflex coordination patterns observed during interactions with the stiff and compliant environments. These results suggest that reflex modulation occurred through altered use of fixed muscle coordination patterns rather than through a change in reflex coordination.

Abstract:
Deep learning (DL) models have emerged in recent years as the state-of-the-art technique across numerous machine learning application domains. In particular, image processing-related tasks have seen a significant improvement in terms of performance due to increased availability of large datasets and extensive growth of computing power. In this paper we investigate the problem of group activity recognition in office environments using a multimodal deep learning approach, by fusing audio and visual data from video. Group activity recognition is a complex classification task, given that it extends beyond identifying the activities of individuals, by focusing on the combinations of activities and the interactions between them. The proposed fusion network was trained based on the audio–visual stream from the AMI Corpus dataset. The procedure consists of two steps. First, we extract a joint audio–visual feature representation for activity recognition, and second, we account for the temporal dependencies in the video in order to complete the classification task. We provide a comprehensive set of experimental results showing that our proposed multimodal deep network architecture outperforms previous approaches, which have been designed for unimodal analysis, on the aforementioned AMI dataset.

Abstract:
In many visual displays such as virtual environments, human tasks involve objects superimposed on both complex and moving backgrounds. However, most studies investigated the influence of background complexity or background motion in isolation. Two experiments were designed to investigate the joint influences of background complexity and lateral motion on a simple shooting task typical of video games. Participants had to perform the task on the moving and static versions of backgrounds of three levels of complexity, while their eye movements were recorded. The backgrounds displayed either an abstract (Experiment 1) or a naturalistic (Experiment 2) virtual environment. The results showed that performance was impaired by background motion in both experiments. The effects of motion and complexity were additive for the abstract background and multiplicative for the naturalistic background. Eye movement recordings showed that performance impairments reflected at least in part the impact of the background visual features on gaze control.

Abstract:
This paper aims to propose a new fog cloud architecture that performs a joint energy-efficient task assignment (JEETA). The proposed JEETA architecture utilizes the dynamic application-partitioning algorithm (DAPTS), a novel algorithm that efficiently decides and switches the task to be offloaded or not in heterogeneous environments with minimal energy consumption. The proposed scheme outperforms baseline approaches such as MAUI, Think Air and Clone Cloud in many performance aspects. Results show that for the execution of 1000 Tasks on fog, mobile offloaded nodes, JEETA consumes the leas, i.e., 23% of the total energy whereas other baseline approaches consume in between 50%–100% of the total energy. Results are validated via real test-bed experiments and trice are driven efficient simulations.

Abstract:
Snake-like hypermobile robots are thought to be effective in search and rescue task applications, and many research institutions have studied such robots. In prior research, we developed an active-joint activewheel snake-like robot, ACM-R4.1, which had a watertight structure and joint torque sensors that also acted as a torque limiter. Although R4.1 was highly robust in severe environments and had high terrain adaptability, we found problems that had to be overcome, such as getting stuck in rough terrain. We therefore propose a more practical snake-like robot, ACMR4.2, in order to maximizemobility performance. The main features of R4.2 are as follows: (1) thin yaw axis joints, (2) light-weight plastic housing made by vacuum injection method, and (3) wheels those were wider than those of R4.1. We tested R4.2 performance and found that it showed higher traversability than R4.1.

Abstract:
The thesis seeks to develop an account of collaborative activities within the framework of ecological realism—an approach to psychology developed by James J. Gibson in the course of work on visual perception. Two main questions are addressed; one ontological, and one methodological. The ontological question is: given that collaborative activities take place within an environment, what kinds of structure must this environment contain? The response emphasizes the importance of relations which exist between entities, and which connect a given perceiver-actor with the other objects and individuals in its surroundings, and with the relations between those entities. It is held that activities take place within a field of relations. This description draws on the radical empiricist doctrine that relations are real, are external, and are directly perceivable. The present proposal insists that, in addition to being directly perceivable, relations can also be directly acted upon: throwing a ball for a dog is acting on a relation between dog and ball in space. The relational field account of collaboration naturally extends to an account of speaking: people, through their history of acting in an environment populated by other speakers, come to stand in a set of relations with objects and events around them, and these relations can be directly acted upon by others through the use of verbal actions. Verbal actions serve to direct the attention of others to relevant aspects of the environment, and this allows us as speakers to coordinate and manage one another’s activity. The methodological question is this: granting that the environment may be structured as a field of relations, how are we to conduct our empirical investigations, such that we can ask precise questions which lead to useful insights about how a given collaborative activity is carried out in practice? The central issue here concerns the concept of the task. Psychologists are in the habit of using this term quite loosely, to denote the actions of an individual or a group, in a laboratory or outside. This creates confusion in discussions of collaborative phenomena: who is the agent of a ‘collaborative task’? The definition offered here states that a task is a researcher-defined unit of study that corresponds to a change in the structure of the environment that has a characteristic pattern and that is meaningful from the first-person perspective of a particular actor. On this definition, the task is a tool that allows ecological psychologists to carve up the problem space into specific, tractable questions; the task is the equivalent of the cognitivist’s mental module. Task-oriented psychology encourages us to ask the question: which specific resources is the individual making use of in controlling this particular activity? The methodology is developed through an examination of the alarm calling behaviour of vervet monkeys, which is explained in terms of actions on the relational field, and through an analysis of corpus data from a laboratory-based collaborative assembly game. The relational field model promises to provide a way of studying social and collaborative activities on ecological realist principles. The concluding chapter identifies two particular areas in which the model might fruitfully be developed: in the study of learning, and in the theory of designing objects and spaces for interaction.

Abstract:
abstract: Human-robot interaction has expanded immensely within dynamic environments. The goals of human-robot interaction are to increase productivity, efficiency and safety. In order for the integration of human-robot interaction to be seamless and effective humans must be willing to trust the capabilities of assistive robots. A major priority for human-robot interaction should be to understand how human dyads have been historically effective within a joint-task setting. This will ensure that all goals can be met in human robot settings. The aim of the present study was to examine human dyads and the effects of an unexpected interruption. Humans’ interpersonal and individual levels of trust were studied in order to draw appropriate conclusions. Seventeen undergraduate and graduate level dyads were collected from Arizona State University. Participants were broken up into either a surprise condition or a baseline condition. Participants individually took two surveys in order to have an accurate understanding of levels of dispositional and individual levels of trust. The findings showed that participant levels of interpersonal trust were average. Surprisingly, participants who participated in the surprise condition afterwards, showed moderate to high levels of dyad trust. This effect showed that participants became more reliant on their partners when interrupted by a surprising event. Future studies will take this knowledge and apply it to human-robot interaction, in order to mimic the seamless team-interaction shown in historically effective dyads, specifically human team interaction.

Abstract:
Harvey Cheyne is the over-indulged son of a millionaire. When he falls overboard from an ocean liner he is rescued by a Portuguese fisherman and, initially against his will, joins the crew of the We're Here for a summer. Through the medium of an exciting adventure story, Captains Courageous (1897) deals with a boy who like Mowgli in The Jungle Book, is thrown into an entirely alien environment. The superstitious, magical world of the sea and the tough, orderly, physical world of the boat form a backdrop to Harvey's regeneration. Kipling describes the fascination skills of the schooner fishermen who would soon be made redundant by the twentieth century, and makes the ship function as a convincing model for a society engaged in a difficult and dangerous task. The introduction to this edition examines its place among other maritime novels and among Kipling's own work, and explanatory notes clarify the seafaring terms and historical and geographical references.

Abstract:
This chapter illustrates how computer-mediated discourse analysis (CMDA) can be used systematically to investigate online communication. It argues that intended outcomes of learner interactions, such as meaningful dialogue and joint knowledge construction, must be identified and analyzed to better understand the effectiveness of online learning activities. The CMDA approach is illustrated through analysis of a synchronous chat held by a three-person graduate student group as it completed a course assignment at a distance. Findings from the analysis reveal that while all group members participated in the task and communicated with mutual respect, a cooperative rather than collaborative approach was taken, and group members did not challenge initial opinions. These findings can assist with the future instructional design of such online learning tasks. It is hoped that this chapter provides guidance to researchers in identifying intended outcomes of online collaboration and utilizing CMDA to determine whether the outcomes have been met.

Abstract:
The U.S. Navy's at-sea replenishment system is a mobile supply line designed to support the deployed carrier task force (CTF)/cruiser/destroyer (CRUDES) surface action group (SAG) and forward deployed units while at sea. In the Pacific, the main component of the mobile supply line, the combat logistics force (CLF) ship, has become a possible target with the development of the anti-ship ballistic missile. With the ability to target and disable a CLF, an enemy can now disable a deployed CTF/CRUDES fleet by eliminating its required resources. With the goal of preserving the CLF's capabilities to perform its mission while avoiding ASBM threat, the authors consider the possibility of utilizing a “mini-CLF” to shuttle fuel between CLFs operating in a safe environment and warships operating in a threat zone. The authors perform two analyses: they (1) analyze the feasibility of using the Littoral combat ship/joint high-speed vessel, reconfigured as a shuttle to transport resources, and (2) analyze requirements for development of a new class of ships to support the CTF/CRUDES SAG while deployed in the Pacific.

To what level should business bodies should join in the sustainable development activities? Based on the existing literature, this study assimilates conventional as well as Islamic points about environment and sustainable development and contends that whatever explanation of sustainable development one may subscribe, ultimately, each should culminate in environmental concern. This study contends that Islamic style is more friendly to environmental protection and issues touching sustainable development have moral, social and ethical responsibility. With intense commitment of the businesses in the matter of Islamic ethics to equity, justice and wellbeing of humans, it demands that business organisations in the Islamic and other countries should participate in the sustainable development endeavours. Because of ethics of environmental aspects in Islam, the value chains of suppliers through customers, many companies may be alert for the environmental characteristics and effects of their businesses.

Abstract:
A Cable-Driven Robotic Arm (CDRA) possesses a number of advantages over the conventional articulated robotic arms, such as lightweight mechanical structure, high payload, fault tolerance, and most importantly, safe manipulation in the human environment. As such, a mobile manipulator that consists of a mobile base and a CDRA can be a promising assistive robot for the aging or disabled people to perform necessary tasks in their daily life. For such applications, a CDRA is a dexterous manipulator that consists of a number of cable-driven joint modules. In this chapter, a modular design concept is employed in order to simplify design, analysis, and control of CDRA to a manageable level. In particular, a 2-DOF cable-driven joint module is proposed as the basic building block of a CDRA. The critical design analysis issues pertaining to the kinematics analysis, tension analysis, and workspace-based design optimization of the 2-DOF cable-driven joint module are discussed. As a modular CDRA can be constructed into various configurations, a configuration-independent kinematic modeling approach based on the Product-of-Exponentials (POE) formula is proposed. The effectiveness of the proposed design analysis algorithms are demonstrated through simulation examples.

Abstract:
Group decision support systems (GDSSs) which aim at increasing some of the benefits of collaboration and reducing the inherent losses are interactive information technology-based environments that support concerted and coordinated group efforts toward completion of joint tasks (Dennis, George, Jessup, Nunamaker, & Vogel, 1998). The term group support systems (GSSs) was coined at the start of the 1990’s to replace the term GDSS. The reason for this is that the role of collaborative computing was expanded to more than just supporting decision making (Patrick & Garrick, 2006). For the avoidance of any ambiguities, the latter term shall be used in the discussion throughout this paper

Abstract:
Simultaneous operations can be defined as conducting independent operations in which the course of any operation may impact the safety of personnel, equipment, and environment of another operation. Operations are meant in terms of performing drilling, completion, workover, and construction or production activities simultaneously, mainly at offshore facilities. In general, they have an impact on the installation safety procedures and contingency planning program. Thus, for the purpose of performing simultaneous operations, they must comply with organizational safety and technological requirements. They are to be coordinated through joint planning efforts by supervisors who plan and direct activities. Typical chain-of-command as well as simultaneous operations decision making process flow diagrams are presented in this chapter. Basic steps to be regarded are performing risk assessment, assess and control risks, monitor the simultaneous tasks and communicate the control measures. Communication is the key to performing these tasks safely.

Ecoradar (www.ecoradar.org / www.oekoradar.de) is the name of an innovative Internet portal that sets out to use the simplest and most persuasive means to motivate others to implement sustainable management in those enterprises that have so far taken little or no interest in this subject. This major project, in which over 80 German enterprises and institutions participated, is part of the new funding focus “Integrated Environmental Protection – Instruments for Sustainable Business Management” set by the German Federal Ministry of Education and Research. The primary task of the portal is the creation of an environmental management community. The purpose of this article is to show the structure and elements of the ecoradar community. Both the creation of a “culture of trust” among the participating enterprises and the strategy of successful integration of the joint project partners are of specific interest. In the following, the content models are presented and the article examines the ability of the ecoradar community to develop, share and use the available knowledge by using the tools of knowledge management.

Abstract:
Domains such as disaster rescue, security patrolling etc. often feature dynamic environments where allocations of tasks to agents become ineffective due to unforeseen conditions that may require agents to leave the team. Agents leave the team either due to arrival of high priority tasks (e.g., emergency, accident or violation) or due to some damage to the agent. Existing research in task allocation has only considered fixed number of agents and in some instances arrival of new agents on the team. However, there is little or no literature that considers situations where agents leave the team after task allocation. To that end, we first provide a general model to represent non-dedicated teams. Second, we provide a proactive approach based on sample average approximation to generate a strategy that works well across different feasible scenarios of agents leaving the team. Furthermore, we also provide a 2-stage approach that provides a 2-stage policy that changes allocation based on observed state of the team. Third, we provide a reactive approach that rearranges the allocated tasks to better adapt to leaving agents. Finally, we provide a detailed evaluation of our approaches on existing benchmark problems.

Abstract:
Active learning agents typically employ a query selection algorithm which solely considers the agent's learning objectives. However, this may be insufficient in more realistic human domains. This work uses imitation learning to enable an agent in a constrained environment to concurrently reason about both its internal learning goals and environmental constraints externally imposed, all within its objective function. Experiments are conducted on a concept learning task to test generalization of the proposed algorithm to different environmental conditions and analyze how time and resource constraints impact efficacy of solving the learning problem. Our findings show the environmentally-aware learning agent is able to statistically outperform all other active learners explored under most of the constrained conditions. A key implication is adaptation for active learning agents to more realistic human environments, where constraints are often externally imposed on the learner.

Abstract:
The Association of Research Libraries (ARL)/Canadian Association of Research Libraries (CARL) Joint Task Force on Research Data Services formed in 2020 with a two-fold purpose: (1) to demonstrate and commit to the roles research libraries have in stewarding research data and as part of institution-wide research support services and (2) to guide the development of resources for the ARL and CARL memberships in advancing their organizations as collaborative partners with respect to research data services in the context of FAIR (findable, accessible, interoperable, and reusable) data principles and the US National Academies’ Open Science by Design framework. Research libraries will be successful in meeting these objectives if they act collectively and are deeply engaged with disciplinary communities. The task force formed three working groups of data practitioners, representing a wealth of expertise, to research the institutional landscape and policy environment in both the US and Canada. This report presents the task force’s recommendations for the roles of research libraries with regard to research data principles, policies, and approaches to managing research data. The report also offers strategies for discipline-specific research data approaches, priorities for automation of processes, economic models to scale and sustain shared resources, prioritization of research data to steward, and decision-making rubrics.
