Taking into account the need of handling hybrid information with uncertainty in human decision making, a new belief rule-base inference methodology (RIMER) has been recently proposed. RIMER approach and its relevant extensions have proved to be highly positive solving decision problems. However, for an end user it is difficult to implement the methods and algorithms from the raw equations in order...
Human-machine collaborative teleoperation systems were introduced to overcome limitations of state-of-the-art teleoperation systems by using a virtual assistant that supports the human operator in the execution of a task. Since assistances are highly task-dependent a correct classification of the currently performed task is paramount. In this paper, we present a novel approach for improving task classification...
The advantage of virtual maintenance technology makes it achievable to analyze the characters and elements about maintenance safety before equipment manufacturing. After relating maintenance safety with ergonomics analysis, a credible maintenance safety assessment could be carried out and corresponding suggestion on maintenance safety design will be given. Furthermore, detailed information will be...
Water resource security is a globally environmental problem. This study examines three stages through which the rivers and lakes in Jianghan Plain has gone. 1) Before Holocene, merely affected by climate and Geologic structures, the lake water and river water exchanged freely. 2) In early and middle Holocene, water exchange between the lakes and rivers remained unrestrained, but the minor impact from...
The speed quick, the large volume of traffic highway has provided good convenient for the vehicles journey, but some especially heavy big accidents bring the life and property safety serious threat, the analysis on to the highway safe influence factors, pointed out the highway movement security is by essential factor constitutions and so on the human, vehicle, road, environment and management, analysis...
The deterioration of traditional environmental problems has threaten the human security in worldwide and the environmental security has come into being. Inrecent research status of environmental security, the authors put a new research concept that researching the environmental security problems in perspective of macro-security. Environmental security, considered as one of the important branches of...
Reason's (1990) “Swiss cheese” model of human error integrates the human error perspectives into a single unified framework. The original description of his modal was geared toward academicians rather than practitioners. The Human Factors Analysis and Classification System, HFACS (Douglas A. Wiegmann and Scott A. Shappell, 2003) was specifically developed to define the latent and active failure implicated...
In this paper we present a novel control architecture for realizing human-friendly behaviors and intuitive state based programming. The design implements strategies that take advantage of sophisticated soft-robotics features for providing reactive, robust, and safe robot actions in dynamic environments. Quick access to the various functionality of the robot enables the user to develop flexible hybrid...
Modeling and predicting human behavior is indispensable when industrial robots interacting with human operators are to be manipulated safely and efficiently. One challenge is that human operators tend to follow different motion patterns, depending on their intention and the structure of the environment. This precludes the use of classical estimation techniques based on kinematic or dynamic models,...
This paper addresses the motion planning problem while considering Human-Robot Interaction (HRI) constraints. The proposed planner generates collision-free paths that are acceptable and legible to the human. The method extends our previous work on human-aware path planning to cluttered environments. A randomized cost-based exploration method provides an initial path that is relevant with respect to...
This article accompanies a video that presents a bimanual haptic device composed of two DLR/KUKA Light-Weight Robot (LWR) arms. The LWRs have similar dimensions to human arms, and can be operated in torque and position control mode at an update rate of 1 kHz. The two robots are mounted behind the user, such that the intersecting workspace of the robots and the human arms becomes maximal. In order...
This paper examines the collaborative underpinning of sustainability and suggests the adoption of collaboration as a basis for developing a Sustainable Lens. A framing reference of sustainable practice is used to provide direction to a consideration of the relationship between sustainability and collaboration. This is then used to prompt a discussion of research implications.
The extension method based on entropy weight is a new safety evaluation method. Entropy weight, which is an objective weight, was ascertained by entropy theory. As a result, the subjectivity in ascertaining the weights of more factors in lower hierarchy was avoided. The comprehensive correlative degree was taken as the evaluation criteria in this method. Therefore the subjectivity of evaluation model...
Harmonious culture originates from China's classical culture and spreads to East Asia in ancient time. This culture refers to the moral ideas of “Kindheartedness”, “Harmony”, “Trustworthy”, “Gold Mean”, “Keep Friendly and Harmonious Relations in spite of Differences between People”, “Concord is highly valued”, “Peaceful Coexistence” and the like, which are the recognized principles in dealing with...
This paper firstly gives a construction safety evaluation system based on previously researches. Secondly, it gives the concept of intuitionistic fuzzy sets concisely. Then, intuitionistic fuzzy TOPSIS method is introduced. Finally, a numerical example for safety evaluation is given to illustrate application of the method.
Unmanned Aircraft System (UAS) has been primarily used in the military domain, and their use has increased tremendously in the last decade. UAS provide several distinct operational capabilities and cost advantages compared to manned aircrafts in most situations. It has long been postulated that use of Unmanned Aircraft Systems (UAS) in the civil domain will enable overall improvement in effectiveness...
In electric field generated by ultra high voltage overhead lines, electric charges are induced at surface of human body. These electric charges alter electric field of human body and adjoining space. In order to study the influence of human body, a human body model is placed under ultra high voltage overhead lines and electric field produced by the overhead lines is calculated. Charge simulation method...
With China's rapid economic development, the strong electricity demand, power shortages have become a major economic and social development factors, so that sustainable economic development of China's power has increasingly become the focus of attention. Sustainable development of circular economy is in line with the strategic situation requires the product of human society and economic system structure...
Specific Absorption Rate (SAR) averaged over 10 g, 1 g and 0.1 g mass of head tissue induced inside a realistic grounded human head in the near-field of a half-wave radiating dipole antenna has been computed using Finite Difference in Time Domain (FDTD) method. The head is modeled using voxel based anthropomorphic phantom data considering the electrical parameters of different anatomical internal...
