Obstructive Sleep Apnea (OSA) is one of the most common breathing disorder, affecting approximately 27% of U.S. adults. Limited data have suggested that OSA causes cerebral autoregulation impairment, thus being an important risk factor to stroke. The objective of this paper is to investigate and measure the relation between arterial blood pressure (BP) and cerebral blood flow velocity (CBFV) in simulated...
Name-your-own-price (NYOP) is a successful business model for high timeliness commodity. Consumers care not only price of commodity, but also the utility of commodity which much more attributes of commodity offer to consumers in addition to price. The researches on NYOP have studied the optimal game strategies about the buyer and sellers based on the price. Different from the existing literature,...
The use of sparse representations in signal and image processing is gradually increasing in the past several years. Considering the relativity among the multi-polarimetric SAR images, a new compression scheme for multi-polarimetric SAR image based sparse representation and super-resolution is proposed. Multilevel dictionary is learned iteratively in the 9/7 wavelet domain using one channel SAR image,...
This paper investigates the joint decisions on inventory and pricing for a dual-channel supply chain with the general discrete asymmetric information, where the channel system consists of one traditional channel which is operated by a retailer and one online channel which is operated by a manufacturer. Some interesting insights are found that the joint decision model with the general discrete asymmetric...
Due to all bands of hyperspectral data have the same imaging area, it is reasonable to believe that the dictionary can sparse represent one band may also represent the other bands sparsely. Based on this property, this paper presents a new compression frame for hyperspectral data using sparse representation, and a simplified algorithm under this frame is also proposed. The basic idea of the proposed...
Uncertainty in the battle field is an important factor affecting the decisions of the commanders of operation. Based on the uncertainty of the task and the complexity of the equipment support system, the article adopts the systematic resource capability evaluation mode calculated by grading. In consideration of the uncertainty of task requirement, resource loss and task process, the article adopts...
Data similarity measurement is an important direction for data mining research. This paper is concentrated on the issue of protecting the underlying attribute values when sharing data for the similarity of objects measurement and proposes a simple data transformation method: Isometric-Based Transformation (IBT). IBT selects the attribute pairs and then distorts them with Isometric Transformation....
Solid state lighting is a good alternative light source with reduced energy consumption. Light-emitting diode (LED) is very efficient in turning electrical energy into light. LED has a number of advantages over the traditional light sources. The optical performance of the LED component is very critical. In general, white light can be obtained by applying phosphor on a blue LED chip. The blue light...
In this paper, we propose a method for human segmentation in videos, extending the recent locally competing 1SVM model. There are only local color distributions to be made use of in the model. To generate a consistent segmentation from complex environments, first, we assume we obtain a bounding box around human by using the human detector. Then we incorporate shape prior information inside the bounding...
Femtocells constitute an economical solution conceived for improving the indoor coverage, which are capable of achieving a high network capacity. In order to guarantee a high Area Spectral Efficiency (ASE), femtocells have to reuse the spectrum of macrocells. As a result, the performance of both the femtocells and macrocells may suffer owing to the near-far effects. In this paper, we investigate the...
Cooperative Multiple Point (CoMP) transmission aided Distributed Antenna Systems (DAS) are proposed for increasing the received Signal-to-Interference-plus-Noise-Ratio (SINR) in the cell-edge area of a cellular system employing Fractional Frequency Reuse (FFR) in the presence of realistic imperfect Channel State Information (CSI) as well as synchronisation errors between the transmitters and the receivers...
To satisfy several standards of wireless systems, the wideband phase shifters become essential. In this paper, we present the design and testing of a compact wideband 90° phase shifter with small phase error using CRLH transmission line. The wideband phase shifter is obtained by subtracting of two phase shift parts. The properties of the CRLH transmission line are analyzed and the empirical formula...
Wavelet analysis is widely used in signal processing. It is applied to the component recognition of multi-component three-dimensional fluorescence spectra in this paper. After the scattering peaks removed by the delaunay triangulation interpolation, the fluorescence spectra are transformed with the coif2 wavelet and the discrimination method is established by weighted least square regression. It is...
Fluorescence image-guided surgery (FIGS) improves intraoperative visualization of critical structures. We describe the advancement of handheld and minimally invasive imaging hardware, coupled with myelin-targeting contrast agents, to bring FIGS nerve labeling closer to clinical translation.
In this paper, we study the issue of generating pronunciations for training and decoding with an ASR system for Pashto in the context of a Speech to Speech Translation system developed for TRANSTAC. As with other low resourced languages, a limited amount of acoustic training data was available with a corresponding set of manually produced vowelized pronunciations. We augment this data with other sources,...
Three dimensional network-on-chip (3D NoC) has been suggested as a potential alternative to solve insurmountable problems in 2D field such as global wire length and packet latency for many years. And the mapping problem plays an import role in 3D NoC design which will have a great influence on overall system performance. In this paper, we mainly focus on the latency-aware mapping for 3D NoC. Differing...
The achievable throughput of the entire cellular area is investigated, when employing fractional frequency reuse techniques in conjunction with realistically modelled imperfect optical fibre aided distributed antenna systems (DAS). Given a fixed total transmit power, a substantial improvement of the cell-edge area's throughput can be achieved without reducing the cell-centre's throughput. The cell-edge's...
Although photorealistic computer graphics (PRCG) attempt to deceive our eyes, we can distinguish them from photographic images (PIM, i.e. natural images) depending on approaches of constructing discriminating features and using machine learning and data mining technique to obtain statistical regularity as the prior work in [3,4]. This paper is aiming to find the different contribution of different...
Whether monetary policy should directly respond to asset boom-bust cycles has been in debate for decades. This paper tries to answer the question from the collateral channel of assets on real economy. By adding a partially endogenous financial shock in a reduced-form New Keynesian model, we find optimal monetary policy exists in the trade-off between current economic growth and future financial instability...
we consider cross-layer design frameworks and performance comparison of HARQ schemes in cooperative relay networks with imperfect channel state information (CSI). Firstly, we propose a state transition models to analyze and calculate the HARQ average packet error rate (PER) and latency performance over Nakagami-m channel with imperfect CSI for relay networks; Secondly, By combing the adaptive modulation...
