Numerical Simulation Method of Scoliosis Orthosis Considering Muscle Factor
Journal of Shanghai Jiaotong University (Science) - Tập 28 - Trang 486-494 - 2022
Adolescent idiopathic scoliosis seriously affects the physical and mental health
of adolescents. In the past, the research on therapeutic orthosis ignored the
influence of muscle factors. Aimed at this problem, based on the principle of
reverse engineering, through the spine computed tomography data model of
three-dimensional reconstruction, muscle forces around the spine are imported
into the spi...
IoT System for Intelligent Firefighting in the Electric Power Industry
Journal of Shanghai Jiaotong University (Science) - Tập 26 - Trang 686-689 - 2021
Traditional fire safety management in the electric power industry has
significant drawbacks, including a lack of data, difficulty of maintenance, lack
of supervision, and lack of interaction. This type of management lags behind
current advanced safety management concepts such as “gate advancement” and “full
process management”, and it fails to meet the needs of future energy internet
construction ...
Safety Evaluation Method for Long-Term Operation of Metro Based on Combination Weighting Method
Journal of Shanghai Jiaotong University (Science) - Tập 25 - Trang 700-705 - 2020
Metros are critical infrastructure in big cities and evaluation of their safe
operation is of increasing importance. To make a reasonable safety evaluation
for the metro during operation, this paper establishes a rational safety
evaluation model based on long-term monitoring data of Shanghai Metro Line 2.
Four evaluation indicators, i.e., absolute settlement, relative curvature,
deformation rate a...
Research on high power inter-channel crosstalk attack in optical networks
Journal of Shanghai Jiaotong University (Science) - Tập 20 - Trang 7-13 - 2015
While all-optical networks become more and more popular as the basis of the next
generation Internet (NGI) infrastructure, such networks raise many critical
security issues. High power inter-channel crosstalk attack is one of the
security issues which have negative effect on information security in optical
networks. Optical fiber in optical networks has some nonlinear characteristics,
such as self...
Semantic-based knowledge categorization and organization for product design enterprises
Journal of Shanghai Jiaotong University (Science) - Tập 20 - Trang 106-112 - 2015
Former knowledge engineering research aimed at boosting automatic reasoning.
However recent knowledge management research focused on promoting the knowledge
sharing and reusing among the people. Because of the different aims between the
two directions, former knowledge representation schemata, such as rule based
representation, frame from knowledge engineering research does not fit to the
current ...
Hierarchy-Based Adaptive Generalized Predictive Control for Aerial Grasping of a Quadrotor Manipulator
Journal of Shanghai Jiaotong University (Science) - Tập 24 - Trang 451-458 - 2019
In this paper, an adaptive generalized predictive control (GPC) based on
hierarchical control strategy is designed for a quadrotor with a robotic arm.
For this nonlinear and coupled system, a two-layer control structure is adopted
to achieve more precise trajectory tracking and keep the tracking performance
after aerial grasping. The inner-layer controller is a proportional-derivative
(PD) control...
Dynamic analysis of the biped ice-skater robot of passive wheel type
Journal of Shanghai Jiaotong University (Science) - Tập 13 - Trang 122-128 - 2008
A new passive wheel type of biped ice-skater robot (BISR) subjected to
nonholonomic constraints was presented on the basis of ice-skating principle.
Its motion principle and construction were discussed. After the model was
simplified and the coordinate systems were established, the motion differential
equations of the robot were obtained with the generalized Lagrange-Maggi
equation when the nonhol...
Soft-sensing method with online correction based on semi-supervised learning
Journal of Shanghai Jiaotong University (Science) - Tập 20 - Trang 171-176 - 2015
Soft sensing has been widely used in chemical industry to build an online
monitor of the variables which are unmeasurable online or measurable online but
with a high cost. One inherent difficulty is insufficiency of the training
samples because the labeled data are limited. Besides, the traditional
soft-sensing structure has no online correction mechanism. The forecasting
result may be incorrect i...
Distribution system optimization planning based on plant growth simulation algorithm
Journal of Shanghai Jiaotong University (Science) - Tập 13 - Trang 462-467 - 2008
An approach for the integrated optimization of the construction/expansion
capacity of high-voltage/medium-voltage (HV/MV) substations and the
configuration of MV radial distribution network was presented using plant growth
simulation algorithm (PGSA). In the optimization process, fixed costs
correspondent to the investment in lines and substations and the variable costs
associated to the operation...
Research of consistency maintenance mechanism in real-time collaborative multi-view business modeling
Journal of Shanghai Jiaotong University (Science) - Tập 20 - Trang 86-92 - 2015
Real-time collaborative editing (RTCE) can support a group of people
collaboratively work from distributed locations at the same time. However,
consistency maintenance is one key challenge when different types of conflicts
happen. Therefore a common synchronous mechanism is proposed to support
consistency maintenance in the process of multi-view business modeling. Based on
operation analysis on di...
