Spinal motion measurement during dynamic conditions may help identify differences between individuals with and without low back pain (LBP). The purpose of this paper is to demonstrate the feasibility of an inertial sensing based, portable spinal motion measurement system for investigating the differences of the spinal motions between an LBP group and a healthy control group. During a fast flexion/...Show More
In this paper, Cascade Forward Back Propagation (CFBP) algorithm based on artificial neural network is proposed for the estimation of longitudinal aerodynamic parameters of the aircraft.

Despite the important role played by muscle co-contraction in stabilizing and stiffening the spine during daily activities, the effects of multi-movement models on the lumbar co-contraction are yet to be explored. This study explores the co-contraction features of lumbar muscle in subjects with and without low back pain while they perform four different movements namely forward, backward, left fle...Show More
Medical images of MRI, CT and X-ray are the digital form of biological features of human organs. The bulk data of medical images generated by medical imaging processes requires different image compression techniques to reduce the storage space with considerable image quality.

We are developing a passive power-assist supporter called Smart Suit Lite, which is a compact and lightweight power-assist device that utilizes the restoring force of elastic belts. Smart Suit Lite is designed not only to support muscles but also to stabilize the torso similarly to a corset. However, because a corset is always tight around the waist, negative effects caused by long-term use has be...Show More

Software architecture slicing extracts the right software architecture to provide reference or design guiding for developing software architecture. It will reduce the complexity of the requirement specifications based on a selected slicing criterion of either the component or the connector, but little effort has been made regarding the relationship between forward slicing and backward slicing anal...Show More

A number of neural networks can be formulated as the linear-in-the-parameters models. Training such networks can be transformed to a model selection problem where a compact model is selected from all the candidates using subset selection algorithms. Forward selection methods are popular fast subset selection approaches. However, they may only produce suboptimal models and can be trapped into a loc...Show More
The Improved Forward Backward Method and Symmetric Successive over Relaxation (SSOR) method are proposed to compute electromagnetic (EM) scattering from 1-D dielectric rough surfaces. In addition the Spectral Acceleration (SA) technique is applied to reduce the computational complexity of each matrix-vector product from O(N2) to O(N). The proposed methods are referred as IFBM-SA and SSOR-SA. They ...Show More

Trellis codes, including Low-Density Parity-Check (LDPC), turbo, and convolutional code (CC), are widely adopted in advanced wireless standards to offer high-throughput forward error correction (FEC). Designing a multistandard FEC decoder is of great challenge. In this paper, a trellis application specified instruction-set processor (TASIP) is presented for multistandard trellis decoding.

On time diagnosis of spinal cord problems is essential because of patient pain and cost of treatment. To alleviate this hazard, in this research a fuzzy rule-based expert system is proposed to diagnosis spinal cord problems and clarify whether a MRI scan is necessary or not. The knowledge representation of this system is provided from high level, based on lifestyle of the patient and historical da...Show More
We prove the existence and the uniqueness of the solutions of a new type of general forward-backward stochastic differential equations (FBSDEs), where the forward equations are Itô stochastic delayed ones and the backward equations are anticipated back stochastic differential equations, under some certain “monotonicity” conditions. By using the solutions of the FBSDEs we discuss the anticipated ba...Show More
In this paper, we showed a method to forecast the stock price using neural networks. Predicting the stock market is very difficult since it depends on several known and unknown factors. In recent years, one of the techniques that have been used popularly in this area is artificial neural network. The power of neural network is its ability to model a nonlinear process without a priori knowledge abo...Show More

Doubly hidden Markov models (DHMMs) have been widely used to analyze a type of time process whose driving factors are hierarchical and hierarchically correlated. A common issue of these models is that they implicitly assume that the dwell time of any system state is constant or exponentially distributed. This property comes from the standard hidden Markov models and causes the DHMM to limitations ...Show More

Spotlight bistatic forward-looking synthetic aperture radar (BFSAR) is a valid tool in the precise surveillance and attacking mission. Because the low frequency ultrawideband (UWB) spotlight BFSAR has the complicated range-azimuth coupling, diverse imaging geometry, and long synthetic aperture, etc., the application of frequency-domain algorithms is limited. In this paper, an extended fast factori...Show More
We propose new greedy algorithms for learning the structure of a graphical model of a probability distribution, given samples drawn from the distribution. While structure learning of graphical models is a widely studied problem with several existing methods, greedy approaches remain attractive due to their low computational cost. The most natural greedy algorithm would be one which, essentially, a...Show More
We compare the response spectra between forward and backward direction, and the contour maps of response spectra at certain natural periods. Results indicate: (1) the response spectra in the forward direction is higher than that of the backward direction. For natural period smaller that 2 second, the average response spectra in forward direction is about two times that of the backward direction; f...Show More
