The Journal of Visualization and computer Animation 1992年第1期3卷 13-22页

Department of Mathematics and Computer Science Saint Joseph's University Philadelphia Pennsylvania 19131-1395 United States Computer Graphics Research Laboratory Department of Computer and Information Science University of Pennsylvania Philadelphia Pennsylvania 19104 United States

To facilitate the effective use of strength data in a human‐task simulation environment, we have developed graphical methods to display the multidimensional characteristics of strength data. We use human figures together with two and three dimensional graphical symbols, colours and animations to visualize the effects of different parameters on strength. These displays give a dynamic view of the effects of various parameters on strength, and illustrate safe and forbidden body postures (or regions) in terms of strength capabilities.

29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBS 2007), vol.14

作者： Florian Graglia Jean-Luc Mari Georges Baikoff Jean Sequeira Information and System Science Laboratory (LSIS) Computer Graphics Department (Image & Modèle) Faculté des Sciences de Luminy in Marseille University of Marseille II France Ophthalmologist in Marseille France

In this paper, we present a new approach for contour detection in the frame of OCT images of the cornea. With the aim of detecting upper and lower curves that define the cornea in radial slices, we have elaborated a three step specific method. The first step consists in finding epithelium and endothelium points (we call them anchor points). Then the image is preprocessed to enhance the contrast and to reduce speckle. In the final step both anchor points are used as starting points for the algorithm: we trace the contour of the cornea pixel by pixel from these two points with a weight criterion. Taking into account geometrical knowledge of the cornea enhances the robustness of the technique. We validate our approach on a bank of scans including low quality images.

Asian Test Symposium (ATS)

作者： Zhen Chen Jia Li Dong Xiang Yu Huang Department of Computer Science and Technology Tsinghua National Laboratory for Information Science and Technology Beijing China Integrated Circuit Advaced Process Center Institute of Microelectronics Chinese Academy of Sciences Beijing China Mentor Graphics Corporation Wilsonville OR USA

Large test data volume and high test power consumption are two major concerns for the industry when testing large integrated circuits. Linear decompress or-based compression (LDC) is efficient in reducing test data volume, while X-filling during ATPG can efficiently reduce test power with low overhead. However, traditional X-filling methods cannot be reused in the LDC environment. In this paper, we propose a virtual circuit model to make the linear de-compressor transparent to the external testing. As a result, existing X-filling methods can be reused to reduce test power. Experimental results on benchmark circuits demonstrate the efficiency of the proposed approach.

Mobile Edge Computing (MEC) provides users with low-latency, highly responsive services by deploying Edge Servers (ESs) near applications. MEC allows any edge-hosted application or service to be migrated between different edge resource providers without being locked into a single provider. Nevertheless, due to its complexity and dynamics, the real edge computing environment is prone to errors and failures, reducing the reliability of edge service migration. This paper proposes a novel fault-tolerant method for redundant path service migration. The method utilizes sliding-window-based model and identifies a set of service migration paths, enabling the evaluation of the time-varying failure rate of ESs. The method combines resubmission and replication mechanisms and decides the edge service migration scheme by selecting multiple redundant migration paths. We also conduct extensive simulations and show that our proposed method outperforms traditional solutions in several metrics. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Robotic manipulators offer some unique opportunities to address research and clinical needs. Among those is the potential use of a robotic manipulator to mechanically scan the tissue of interest with biosensors that have limited tissue penetration. In such cases, the robot can serve a dual role. First, it can perform spatial scanning with the biosensor along a pre-selected path inside the tissue. Second, it can function as the mechanical link to spatially co-register the data collected with the biosensor and the images of a guidance modality. Herein, we describe a robotic system to mechanically scan with a light-induced fluorescence (LIF) sensor and co-register LIF data to the guiding modality of MRI. Specifically, a custom-built MR-compatible endoscope was integrated onto the end-effector of an MR-compatible manipulator to collect MRI-guided LIF 1D scans. A miniature radiofrequency (RF) coil attached onto the end-effector was used as a fiducial marker for co-registering LIF and MRI. This mechanically scanning system was investigated on two compartment phantoms, each with different optical agents. Those studies demonstrated “robot-assisted” multi-modality co-registration, i.e. the spatial distribution of the LIF signals matched with the MR guiding images. The system can incorporate additional sensors for collecting complementary biochemical information.

The elderly represent a valid group of users who can potentially benefit greatly from engaging with technology, such as healthcare systems or playing digital games. Yet, less attention has been given to the significance of senior citizens as technology users, as compared to the common younger population. In an effort to fill in the gap, this workshop aims to investigate the design of technology for senior citizens. To provide for more focused, thus more productive discussion, we will use elderly mobile phone games as a case in point here. The overarching objective is to understand what can help to make for better and more meaningful use of interactive applications and technology by the elderly, for instance, games on the mobile phone. © 2010 Copyright is held by the author/owner(s).

Mobile Ad hoc networks (MANETs) have the characteristics of distribution, self-organization and mobility. PUMA, as a mesh-based multicast routing protocol for MANET, has been proved to perform better than other comparable multicast algorithms because of its effectiveness and robustness. Recently, cognitive radio technology has been applied to solve the scarcity problem of radio spectrum resources. In this paper, we combine PUMA with cognitive radio technology and propose a novel multicast routing algorithm, which is named as CR-PUMA for MANET. In CR-PUMA, node detects the available channels and selects a suitable one to send data packets to its next-hop neighbor. A cross-layer approach, which goes across the physical layer, link layer and network layer, is employed in our algorithm. Simulation experiments show that CR-PUMA attains a superior performance in terms of packet delivery ratio and throughput. © 2018 The authors and IOS Press. All rights reserved.

A number of techniques in recent years have demonstrated photoreal relightable image based models. In particular, a number of efforts have focussed on capturing images under many illumination conditons, allowing for this relighting to be performed directly from captured data without making simplifying assumptions about the material properties or light transport within the scene. These approaches can often be considered attempts at characterizing or measuring the reflectance field of the scene, a prospect which remains elusive given the high dimensionality of the reflectance field.

The AAAI-10 workshop program was held on July 11-12, 2010, at the Westin Peachtree Plaza in Atlanta, Georgia. The workshop program included 13 workshops covering a wide range of topics in artificial intelligence. There were several presentations on particular formalisms for combining the levels of planning from the perspectives of classical planning, motion planning, POMDPs, search-based planning, and temporal logic-based constraints. Henry Lieberman from Massachusetts Institute of Technology Media laboratory presented work developing a platform for knowledge acquisition and usage from expert users, built upon experience with eliciting information from nonexperts in a collaborative manner. The objective of the AAAI Workshop on Goal-Directed Autonomy (GDA) was to encourage discussion and novel contributions on intelligent agents that can self-select their goals. Jeremy Baxter from QinetiQ focused on user interaction, while Nick Hawes described a goal-directed reasoning framework for controlling a mobile robot.
