Independent vector analysis (IVA) has exhibited promising applications to complex-valued fMRI data, however model order effects on complex-valued IVA have not yet been studied. As such, we investigate model order effects on IVA using 16 task-based complex-valued fMRI data sets. A noncircular fixed-point complex-valued IVA (non-FIVA) algorithm was utilized. The model orders were varied from 10 to 160...
Vehicle safety airbags can protect occupants from vehicle collisions, but there are still some shortcomings, thus need to be constantly improved. In occupant restraint system simulation, the establishment of a reasonable airbag model determines whether the simulation results are consistent with the actual test results. The aim of this study is to establish a precise airbag model for vehicle occupant...
To study the relationship between the hardness of kiwi-fruit and its near infrared diffuse reflectance spectroscopy, using near infrared diffuse reflectance spectroscopy and chemical analysis method. And establish a method to realize the nondestructive assessment of hardness, which at room temperature (24 degrees ±2 degrees) conditions, using near infrared spectroscopy (4000~10000cm-1) to test different...
Data integration between various systems of complex product manufacturing enterprises and the resource management issues are the focus of the attention of the management sectors. To solve the problem, the ship manufacturing, for example, this paper detailed analyzing the characteristics of its data storage and description, and according to the MOF element model mechanism, using rule-based routes to...
In order to promote the application value and instruction significance of “structural Keynesian investment multiplier” (abbreviated as SKIM), this paper takes environment consumption and environment input into the second-stage input-output table. It meanwhile proposes a concrete plan of compiling a “second-stage input-output table that incorporates environment factor”, and based on this designs a...
Tensor decomposition of fMRI data has gradually drawn attention since it can explore the multi-way data's structure which exists inherently in brain imaging. For multi-subject fMRI data analysis, time shifts occur inevitably among different participants, therefore, shift-invariant tensor decomposition should be used. This method allows for arbitrary shifts along one modality, and can yield satisfactory...
By means of complex network methods, we construct the Operation SoS network based on simulated data generated by games in large-scale joint operations and analyze the basic statistical characteristics and evolution. Through analyzing, there are three findings: the first one is that the Operation SoS network have the basic characteristics of complex networks, the second one is Operation SoS network's...
This paper presents a novel signal analysis method by combining ICA and EEMD algorithms, which can be used for decomposition and feature extraction of non-stationary random signals. The features of ICA and EEMD algorithm were analyzed. Simulations verified the feasibility of combining the two algorithms. The ICA and EEMD combined algorithm has good validity and practicality in the impact acceleration...
A novel method of moving target identification based on multi-features fusion is proposed in this paper. Firstly, the distribution model of evidence weights is set up by the improved Dempster-Shafter (D-S) algorithm in order to solve the invalidation problem of highly conflict evidences. Then applies particle swarm optimization method to get the optimum evidence weights, which modify the original...
There is time lag between domestic oil product price and international oil price. The speculation caused by such time lag in domestic oil product market has great disturbance on domestic oil product demand. That is, the domestic oil product would be in short supply when international oil price rose. Otherwise, it would be unmarketable. Through SWARM, three category of oil product consumer agents were...
With the developing of industry, maintenance has become an important factor that influences survival and development of the business. There are numerous pieces of equipment in a power plant, but the maintenance requirement is different for respective equipment, so making condition based maintenance in a power plant is a systemic and integrative activity in maintenance management. As an interdisciplinary...
With the developing of industry, maintenance has become an important factor that influences survival and development of business. As an interdisciplinary activity, maintenance management needs technical support from computer decision support system when using that knowledge. There are numerous pieces of equipment in a power plant, but the maintenance requirements are different for different equipment...
Channel mismatch, including amplitude and phase mismatch, has severely affected the performance of space-time adaptive processing (STAP). In order to ascertain the specification of the effects on STAP, theory analysis of relation between clutter covariance matrix (CCM) with and without channel mismatch is done based on the model provided by literature, and the effect to signal is also analyzed. In...
