In this paper, we propose a cybersecurity exercise system in a virtual computer environment. The human resource development for security fields is an urgent issue because of the threat of cyber-attacks, recently, is increasing, many incidents occurring, but there is a not enough security personnel to respond. Some universities and companies are conducting education using a commercial training system on the market. However, built and operates the training system is expensive, therefore difficult to use in higher education institutions and SMEs. However, to build and operates, the training system needs high cost, thus difficult to use in higher education institutions and SMEs. For this reason, we developed the CyExec: a cybersecurity exercise system consisting of a virtual computer environment using VirtualBox and Docker. We also implemented the WebGoat that is an OSS vulnerability diagnosis and learning program on the CyExec and developed an attack and defense exercise program.

This paper investigates vision based robot control based on a receding horizon control strategy, as a first step for a predictive visual feedback control. Firstly, the brief summary of the 3D dynamic visual feedback system with eye-in-hand configuration is given. Next, a stabilizing receding horizon control for the 3D dynamic visual feedback system, a highly nonlinear and relatively fast system, is proposed. The stability of the receding horizon control scheme is guaranteed by using the terminal cost derived from an energy function of the visual feedback system. Furthermore, simulation results are assessed with respect to the stability and the performance

We propose an instruction display and a skill level index to evaluate the degree of progress. The instruction display shows an exemplary trajectory. Learners learn the trajectory to be traced through by their joints. The trajectory is generated from a time series data of 3-dimensional coordinates of joints in the human body acquired from the expert motion. The instruction display enables learners to understand the difference between learners' motion and expert's one. The skill level index shows numerically the difference between learners' motion and expert's one. To realize evaluation which does not depend on motion speed, we use continuous dynamic programming (DP) matching. The values obtained from continuous DP matching show learner's skill level. To verify the effect of the instruction display and the skill level index, we experiment with learners who learn left arm motion with the instruction display and report its result

IEEE International Symposium on Intelligent Control (ISIC)

This paper investigates passivity based 3D dynamic visual force feedback control for fixed camera systems. In our approach, we can control not only the position but also the orientation of the robot hand with a contact force by using visual information. The proposed method can be regarded as an extension of the hybrid position/force control to the hybrid vision/force control. The main contribution of this paper is to show that the 3D dynamic visual force feedback system has the passivity which allows us to prove stability in the sense of Lyapunov. Both the passivity of the manipulator dynamics and the passivity of the visual feedback system are preserved. Finally simulation results on 3 DOF planar manipulator are presented to verify the stability of the 3D dynamic visual force feedback system and understand our proposed method simply.

2007 IEEE International Symposium on Industrial Electronics (ISIE 2007), vol.7

作者： Yutaka Abe Akinori Sasaki Hiroshi Hashimoto Hideki Murakoshi Sho Yokota Yasuhiro Ohyama School of Bionics Tokyo University of Technology Tokyo Japan Master Program of Information Systems Architecture School of Industrial Technology Advanced Institute of Industrial Technology Tokyo Japan

In this paper, we propose a method for non-contact measurement of knee load. Joint position data is acquired with image analysis. Masses and centers of gravity on each segment of human body is estimated with a multiple linear regression model. Knee torque is estimated based on kinetics and these data, and it is used index value of knee load. In the proposing method, human body is not restricted and measurement may be performed in a ordinary space without any special equipment set on the floor or wall. The method is effective for preventing knee injuries. The validity of the proposing method is verified with cross-correlation function between the estimated knee load and EMG signals. The knee load increases along with the knee flexion and extension, and is sustained by the torque around the knee exerted by the quadriceps femoris. EMG signal measured on the quadriceps femoris is also index value of knee load. The experiments are performed based on those data. As a result, it is reported that the time derivative of the torque corresponds to the EMG signals in the sense of phase.

THE IMPROVED NAVAL SHIPYARD MANA GEMENT information SYSTEM—A POTENTIAL FOR INCREASED PRODUCTIVITY

引用

Naval Engineers Journal 1979年第2期91卷 192-203页

作者： SISSON, JONATHAN A. USN (RET.) Capt. Jonathan A. Sisson USN (RET.) is a graduate of the United States Naval Academy and received his degree of Master of Science in Naval Architecture from the Webb Institute of Naval Architecture. From 1964 to 1969 he was the Planning & Estimating Superintendent at the Norfolk Naval Shipyard. From 1969 to 1976 he was the Director Naval Shipyard Management Systems Division Naval Sea Systems Command during which period he initiated the development of the improved Shipyard MIS. From December 1976 until his retirement from the Navy on 1 July 1978 he was the Manager Naval Shipyard Management Information System Improvement Program Naval Sea Systems Command. He joined the staff at ORI Inc. Silver Spring Md. in September 1978 and is a member of SNAME and the Society for Management Information Systems.

The standard Naval Shipyard Management information System (Shipyard MIS) in use at the eight United States Naval Shipyards is a computer‐based system that processes data related to virtually every element of naval shipyard operations. It has had almost thirteen years of operation constantly growing and improving along the way. In early 1976 a major improvement program was initiated to modernize this batch processing oriented system to meet the needs of management for information in a more responsive manner. Some of the products of this improvement program offer the potential to shipyard managers for improving productivity. This paper describes some of these products and the challenges to shipyard management to utilize them effectively such that improved performance or productivity and significant cost savings can be realized. © 1979 American Society of Naval Engineers
