Resumen

Attitude, speed, and position of unmanned aerial vehicles are susceptible to wind disturbance. The types, characteristics, and mathematical models of the wind, which have great influence on unmanned aerial vehicle in the low-altitude environment, are summarized, including the constant wind, turbulent flow, many kinds of wind shear, and the propeller vortex. Combined with the mathematical model of the unmanned aerial vehicle, the mechanism of unmanned aerial vehicle movement in the wind field is illustrated from three different kinds of viewpoints including velocity viewpoint, force viewpoint, and energy viewpoint. Some simulation tests have been implemented to show the effects of different kinds of wind on unmanned aerial vehicle’s path and flight states. Finally, some proposals are presented to tell reader in which condition, which wind model should be added to simulation, and how to enhance the stability of unmanned aerial vehicle for different kinds of wind fields.

Resumen

The efficient computation of viewpoints while considering various system and process constraints is a common challenge that any robot vision system is confronted with when trying to execute a vision task. Although fundamental research has provided solid and sound solutions for tackling this problem, a holistic framework that poses its formal description, considers the heterogeneity of robot vision systems, and offers an integrated solution remains unaddressed. Hence, this publication outlines the generation of viewpoints as a geometrical problem and introduces a generalized theoretical framework based on Feature-Based Constrained Spaces (C-spaces) as the backbone for solving it. A C-space can be understood as the topological space that a viewpoint constraint spans, where the sensor can be positioned for acquiring a feature while fulfilling the constraint. The present study demonstrates that many viewpoint constraints can be efficiently formulated as C-spaces, providing geometric, deterministic, and closed solutions. The introduced C-spaces are characterized based on generic domain and viewpoint constraints models to ease the transferability of the present framework to different applications and robot vision systems. The effectiveness and efficiency of the concepts introduced are verified on a simulation-based scenario and validated on a real robot vision system comprising two different sensors.

Resumen

‘A national art library’: if every one of these four words raises questions and demands qualification, together they suggest even more.Art is so elusive and resistant to institutionalisation that no single library - ‘a’ national art library - could possibly have the omniscience and omnipresence (never mind the money) to collect everything: to take a UK example, how many libraries managed to collect the Freeze (1988) exhibition catalogue at the time? And who collected the ‘programme note’ from that one-off performance in a half-derelict warehouse in Penge? Co-operation and collaboration in collection development are needed to maximise the research resources available in any particular nation, to ensure the retention of last or archival copies - and any national art library must surely have a role in this. However, this just sets up a chain of secondary problems - with access and funding at the top of the list. Individual institutions ultimately have their own agendas and priorities: and this even applies to national institutions, where existing collection strengths may skew collecting priorities. Perhaps we have to accept an incomplete but vibrant mosaic: the librarian’s desire for comprehensiveness and universal bibliographic control cannot be achieved in the real world.

Resumen

The spread of hospital infections in high-risk units remains even though infection control and prevention measures are being improved annually. It is associated with factors such as age, severity of the underlying disease, duration of hospitalization, antibacterial therapy, resistance to microorganisms, and the number of invasive procedures. The human resources and the financial distribution in medicine play the key role in controlling infections. Intensive care nurses supervising and taking care of the patients 24 hours a day have an invaluable role in controlling infections and reducing hospital infections. The aim of the study is to find out the nurses' opinions about the factors motivating infection control in the intensive care units and in the department of internal medicine. The study used a quantitative study method-survey (n = 160). The questionnaire included questions about the factors influencing infection control and the factors motivating the nurse. Questionnaires involved nurses in the intensive care units and in the department of internal medicine, who care for patients in Latvian multifunctional regional hospitals. The study suggests that nurses are motivated by both material and non-material motivating factors. The material motivating factors in nurses' viewpoint are maintenance of workplace, the premium of work quality, the premium for night work and overtime, premium for work on holidays, possibility to attend courses and training, vacation pay, as well as environment of work. The non-material motivating factors in nurses' viewpoint are the attitude of the supervisor, being respectful of their workplace, the relations with colleagues, acknowledgment for the work done, the responsibility at work, the pride and respect for the work to be done, the challenges, interesting job and variety in work tasks, as well as the growth and development in the workplace.

Resumen

For luggage inspection, a good 3D impression is needed. This impression can be enhanced either by improving the image quality or by providing multiple viewpoints. An experiment is described in which students had to judge whether two objects in a transparent box were connected with a wire. Subjects using head movements to select the viewpoint were compared with subjects using a knob. Viewpoint selection was limited to horizontal movement. The resolution and the number of grey levels of the image as well as the size and the number of discrete steps of image movement were manipulated. Results show that 16 grey levels are sufficient to detect the wire, but that for a correct decision about connectivity, a freedom of movement of at least 90° is desirable. No difference was found between selecting the desired viewpoint with the head and by knob.

Resumen

Objective We describe a networked, two-user virtual reality (VR) power wheelchair (PWC) simulator system in which an actor (client) and an observer (clinician) meet. We then present a study with 15 observers (expert clinicians) evaluating the effect of three principal forms of viewpoint control (egocentric-egomotion, egocentric-tethered, and client-centric) on the observer’s assessment of driving tasks in a virtual environment (VE). Background VR allows for the simulation and assessment of real-world tasks in a controlled, safe, and repeatable environment. Observing users’ movement behavior in such a VE requires appropriate viewpoint control for the observer. The VR viewpoint user interface should allow an observer to make judgments equivalent or even superior to real-world situations. Method A purpose-built VR PWC simulator was developed. In a series of PWC driving tasks, we measured the perceived ease of use and sense of presence of the observers and compared the virtual assessment with real-world “gold standard” scores, including confidence levels in judgments. Results Findings suggest that with more immersive techniques, such as egomotion and tethered egocentric viewpoints, judgments are both more accurate and more confident. The ability to walk and/or orbit around the view significantly affected the observers’ sense of presence. Conclusion Incorporating the observer into the VE, through egomotion, is an effective method for assessing users’ behavior in VR with implications for the transferability of virtual experiences to the real world. Application Our application domain serves as a representative example for tasks where the movement of users through a VE needs to be evaluated.

Resumen

For the robotic grasping of randomly stacked objects in a cluttered environment, the active multiple viewpoints method can improve grasping performance by improving the environment perception ability. However, in many scenes, it is redundant to always use multiple viewpoints for grasping detection, which will reduce the robot’s grasping efficiency. To improve the robot’s grasping performance, we present a Viewpoint Adjusting and Grasping Synergy (VAGS) strategy based on deep reinforcement learning which coordinates the viewpoint adjusting and grasping directly. For the training efficiency of VAGS, we propose a Dynamic Action Exploration Space (DAES) method based on ε-greedy to reduce the training time. To address the sparse reward problem in reinforcement learning, a reward function is created to evaluate the impact of adjusting the camera pose on the grasping performance. According to experimental findings in simulation and the real world, the VAGS method can improve grasping success and scene clearing rate. Compared with only direct grasping, our proposed strategy increases the grasping success rate and the scene clearing rate by 10.49% and 11%.

Resumen

The article reveals the essence and peculiarities of the personnel reserve formation in the institution of higher education. The functionality of the personnel reserve of the modern higher school is analyzed from two viewpoints: the viewpoint of an institution of higher education (functions are information, personnel planning, resource saving, anti-crisis, regulatory) and the viewpoint of a reservist (career-orientation, motivational, developmental functions). The personnel reserve management is represented by several approaches: classical (training is tied to the competence of a particular position); the personnel reserve management in the context of the concept of talent management (development on the grounds of needs and deficits in the competence of succession pool members); synthetic (the personnel reserve is a self-organized community and a training program). The best thing is to use adaptive control technology in order to regulate relationships between members of the personnel reserve, and assist them in the implementation of professional self-development and self-improvement. Adaptive control is founded on the acme-synergic principles, as it provides favorable conditions for selforganization, self-knowledge, self-understanding, self-determination, self-prediction and self-design, self-actualization and self-realization of a person as a subject of professional activity. Main lines of work of the acme-synergic service are informational-analytical (general department); organizational-designing (prognostic department); acmeologicaltechnological (technological department); psychological (department of acme-synergic support); research (analytical department).

Resumen

Requirements elicitation from multiple human sources involves uncertainty management. Most requirements analysis methods focus on expressing the requirements and ignore the uncertainty inherent in the process of requirements elicitation. This paper proposed a model for requirements elicitation from multiple viewpoints. The model is based on the idea of building internal models of the viewpoints that record their performance in providing information, assessing information, and resolving conflicts between viewpoints. The paper argues that the proposed approach provides a better mechanism in information validation and conflicts resolution. The paper is part of the work reported by the author in Messaoudi (1994).

Texto completo

Resumen

A stochastic pinning approach for multiagent systems is developed, which guarantees such systems being almost surely stable. It is seen that the pinning is closely related to being a Bernoulli variable. It has been proved for the first time that a series of systems can be stabilized by a Brownian noise perturbation in terms of a pinning scheme. A new terminology named “stochastic pinning control” is introduced to describe the given pinning algorithm. Additionally, two general cases that the expectation of the Bernoulli variable with bounded uncertainty or being unknown are studied. Finally, two simulation examples are provided to demonstrate the effectiveness of the proposed methods.

Resumen

The sliding mode control and the model predictive control are connected by the value function of the optimal control problem for constrained fuzzy system. New conditions for the existence and stability of a sliding mode are proposed. Those conditions are more general conditions for the existence and stability of a sliding mode. When it is applied to the controller design, the design procedures are different from other sliding mode control (SMC) methods in that only the decay rate of the sliding mode motion is specified. The obtained controllers are state-feedback model predictive control (MPC) and also SMC. From the viewpoint of SMC, sliding mode surface does not need to be specified previously and the sliding mode reaching conditions are not necessary in the controller design. From the viewpoint of MPC, the finite time horizon is extended to the infinite time horizon. The difference with other MPC schemes is that the dependence on the feasibility of the initial point is canceled and the control schemes can be implemented in real time. Pseudosliding mode model predictive controllers are also provided. Closed loop systems are proven to be asymptotically stable. Simulation examples are provided to demonstrate proposed methods.

Resumen

The role of cortical area V4 in complex shape discriminations was studied by testing the effects of V4 lesions in macaques on the ability to visually discriminate between images of three-dimensional (3D) objects from different viewpoints. Stimuli were presented in pairs in the lower left or lower right visual field quadrants about 4 deg from the fovea, and the monkeys judged on each trial whether the two views were of the same or of different objects. Object similarity was varied to determine a threshold shape difference. V4 lesions caused profound, retinotopic, and apparently permanent disruptions of discrimination, regardless of whether the images represented single or multiple viewpoints. In V4 lesioned portions of the visual field, monkeys could discriminate objects only when they differed much more grossly in shape than was true in control locations. These effects of the lesion were virtually identical for discriminations that had been learned before lesions were placed and for those learned afterwards. As in previous studies, V4 lesions elevated contrast thresholds by approximately a factor of two, but control observations showed that this was not the basis of the disruption of shape discrimination. Manipulation of cues to shape showed that in control locations, monkeys maintained excellent shape discrimination despite a variety of stimulus alterations, whereas in V4 lesioned areas their performance was easily disrupted. This finding suggests that V4 may support visual shape discriminations by facilitating the use of multiple visual cues. However, the fact that single-viewpoint and multiple-viewpoint discriminations were similarly affected indicates that the disruption was not specific to 3D shape discrimination, but may apply to a variety of subtle discriminations.

Resumen

This article examines how consumers’ exposure to the viewpoint of high versus low vertical position changes their risk-taking behavior. The author proposes that consumers’ views of scenery from a high physical elevation induce an illusory sense of control, which in turn intensifies risk taking. Multiple studies show that exposure to the viewpoint of high vertical positions increases risk taking in both laboratory settings (Studies 1a, 1b, and 1c) and real settings (Study 4). In addition, the author demonstrates that an illusory sense of control mediates the effect of an elevated viewpoint on risk taking (Study 2) and that the effect of elevation on risk taking is attenuated when people use a low-level mental construal to process visual information (Study 3).

Resumen

A common way to represent a system's dynamics is to specify how the state evolves in time. An alternative viewpoint is to specify how functions of the state evolve in time. This evolution of functions is governed by a linear operator called the Koopman operator, whose spectral properties reveal intrinsic features of a system. For instance, its eigenfunctions determine coordinates in which the dynamics evolve linearly. This review discusses the theoretical foundations of Koopman operator methods, as well as numerical methods developed over the past two decades to approximate the Koopman operator from data, for systems both with and without actuation. We pay special attention to ergodic systems, for which especially effective numerical methods are available. For nonlinear systems with an affine control input, the Koopman formalism leads naturally to systems that are bilinear in the state and the input, and this structure can be leveraged for the design of controllers and estimators.

Resumen

The ultimate goal of this study is to develop autonomous mobile home healthcare robots which closely monitor and evaluate the patients' motor function, and their at-home training therapy process, providing automatically calling for medical personnel in emergency situations. The robots to be developed will bring about cost-effective, safe and easier at-home rehabilitation to most motor-function impaired patients (MIPs), and meanwhile, relieve therapists from great burden in canonical rehabilitation. In order to achieve this goal, we have developed the following programs/algorithms for monitoring human activities and recognizing human behaviors: (1) control programs for a mobile robot to track and follow a human subject by three different viewpoints; (2) algorithms for analyzing lower limb joint angles from RGB-D images from a Kinect sensor setup at a mobile robot; and (3) algorithms for recognizing human gait behavior. In (1), side viewpoint, front/back viewpoint and a middle angle viewpoint (between two former viewpoints) tracking were developed. In (2), depth image compensation with colored markers was implemented to deal with the skeleton point extraction error caused by mixing-up and frame flying of depth image during tracking and following human subjects by the mobile robot. In (3), we have proposed a hidden Markov model (HMM) based human behavior recognition using lower limb joint angles and trunk angle. Experimental results showed that joint trajectory could be measured and analyzed with high accuracy compared to a motion tracking system, and human behavior could be recognized from the joint trajectory.

Resumen

Current Generative Adversarial Networks (GANs) produce photorealistic renderings of portrait images. Embedding real images into the latent space of such models enables high-level image editing. While recent methods provide considerable semantic control over the (re-)generated images, they can only generate a limited set of viewpoints and cannot explicitly control the camera. Such 3D camera control is required for 3D virtual and mixed reality applications. In our solution, we use a few images of a face to perform 3D reconstruction, and we introduce the notion of the GAN camera manifold, the key element allowing us to precisely define the range of images that the GAN can reproduce in a stable manner. We train a small face-specific neural implicit representation network to map a captured face to this manifold and complement it with a warping scheme to obtain free-viewpoint novel-view synthesis. We show how our approach - due to its precise camera control - enables the integration of a pre-trained StyleGAN into standard 3D rendering pipelines, allowing e.g., stereo rendering or consistent insertion of faces in synthetic 3D environments. Our solution proposes the first truly free-viewpoint rendering of realistic faces at interactive rates, using only a small number of casual photos as input, while simultaneously allowing semantic editing capabilities, such as facial expression or lighting changes.
