Clinical pathways are popular healthcare management tools to standardise care and ensure quality. Measuring pathway conformance and analysing variances gives valuable feedback in the context of care improvement trajectories. The Business Process Model and Notation (BPMN) language and Task-Time matrices are popular ways to model clinical pathways. A key step in variance analysis involves the computation...
Sparse subspace learning has been demonstrated to be effective in data mining and machine learning. In this paper, we cast the unsupervised feature selection scenario as a matrix factorization problem from the view of sparse subspace learning. By minimizing the reconstruction residual, the learned feature weight matrix with the l2,1-norm and the non-negative constraints not only removes the irrelevant...
Nonstandard treatments for cancer patients are commonly seen in hospitals of developing countries like China. So it is crucial to standardize the treatments for cancer with technological means in order to supervise the process of treatments. Widespread of electronic health records (EHRs) has generated massive data sets which are far beyond the capability of traditional computing model. Although there...
Clinical protocols are a popular instrument to document how clinicians are expected to behave under specific conditions. Protocols are typically based on internationally peer reviewed clinical guidelines as well as on hospital-local agreements. Existing techniques for monitoring protocol adherence only support protocol descriptions involving simple sequences and local decision rules. As care and cure...
In order to solve problems caused by various format of simulation data and complex operation flow on collaborative simulation from different software in the development of virtual prototype technology, this article analyzes and designs the SD&PMS(Simulation Data &Process Management System)frames based on three key capacity of simulation capacity management. They are Simulation organization...
Pulsating flow hydraulic system (PHF) which uses the vibration of oil liquid to transfer power is different from conventional hydraulic system. Because of the alternative pulsation of liquid, it's necessary to calculate the vibration characteristic such as amplitude attenuation of pulsating quantity and degree of phase lag at the output and transmission efficiency of the system exactly when the PFH...
With exploiting space deeply, space robot will play a more important role. A simulation system of a three layer structure based on ADAMS, MATLAB and VC++ is present in this paper, which can simulate and analyze the kinematics and dynamics of space robot in the process of capturing and releasing space object. Verification results show that this system can well explain space robot's dynamic and kinetic...
As an important neuron model, the Morris-Lecar (ML) equations can exhibit classes I and II excitabilities with appropriate system parameters. In this paper, the effects of external DC electric field on the neuro-computational properties of ML model are investigated using bifurcation analysis. We obtain the bifurcation diagram in two dimensional parameter space of externally applied DC current and...
In the practical software development, there are many complexities including dynamic behavior and feedback mechanism as well as various interacting factors. Software Engineering education is facing difficulties because students have limited engineering experience and they can hardly understand typical phenomena occurring in software projects. System Dynamics is a continual modeling method describing...
