Saliency detection has been revealed an effective and reliable approach to extract the region of interest (ROI) in remote sensing images. However, most existing saliency methods employing multiple cues ignore intrinsic relationship between different do not distinguish diverse contributions final map. In this paper, we propose a novel self-adaptively feature fusion model for images take advantage improve accuracy ROI extraction. First, channels, namely colour, intensity, texture global...
It has been of great interest to find sparse and/or nonnegative representations in computer vision literature. In this paper we propose a novel method such purpose and refer it as curds whey (NNCW). The NNCW procedure consists two stages. the first stage consider set test image, each which is linear combination images within certain class, by solving regression-type matrix factorization problems. second incorporate these into new representation using group garrote. This particularly...
Abstract Road scene parsing is a crucial capability for self-driving vehicles and intelligent road inspection systems. Recent research has increasingly focused on enhancing driving safety comfort by improving the detection of both drivable areas defects. This article reviews state-of-the-art networks developed over past decade general-purpose semantic segmentation specialized tasks. It also includes extensive experimental comparisons these across five public datasets. Additionally, we...
ABSTRACT Seismic reliability assessments of water and power supply networks are typically conducted under the assumption system independence. This article introduces a novel framework for evaluating seismic interdependent networks, grounded in comprehensive analysis their interdependence mechanisms. The proposed integrates network flow theory Monte Carlo simulation method, leveraging to determine functional status various nodes employing simulations account random factors such as earthquake...
Abstract In order to study the interaction mechanism of fatigue damage and size effect prestressed concrete beams under load, multi‐stage variable amplitude tests three groups with different sizes were carried out. Through research analysis test data it is found that due action cyclic there a in residual bearing capacity beams, is, increase decreases section size. Considering influence degree damage, coefficient original formula modified, new calculation basically consistent change measured...
This paper introduces a mesh less method based on Daubechies (DB) wavelets for 2-D elastic problems. The scaling and wavelet functions of the DB are used as basis to approximate unknown field functions, so there is no need construct costly shape in finite element (FEM) other meshless methods. In addition, properties facilitate implementation method. new analyze problem plain plate with circle hole, numerical results agree well FEM. effective can be extended solve complicated two or three dimensional
In the development of 5G communication systems, multiantenna transmitting architectures and millimeter-wave operating frequency bands are effective ways to improve data rate. order estimate electromagnetic exposure under transmitters installed in portable devices working long-term evolution (LTE) bands, this paper generalizes a low-order model higher orders based on Fourier series expansion for fast accurate evaluation prediction absorption (EA) as function phase difference among multiple...
Abstract Radar tracking plays an important role in the area of early warning and detection system, whose precision is closely connected with filtering algorithm. With development noise jamming technology radar echo signal, linear becomes more difficult to satisfy demands tracking, while nonlinear can solve problems such as non-Gaussian noises. There exist a lot algorithms at present, owning their particular characteristics. this mind, we provide comprehensive overview different including...
The performance of the existing speech enhancement algorithms is not ideal in low signal-to-noise ratio (SNR) non-stationary noise environments. In order to resolve this problem, a novel algorithm based on multi-feature and adaptive mask with deep learning presented paper. First, we construct new feature called multi-resolution auditory cepstral coefficient (MRACC). This which extracted from four cochleagrams different resolutions can capture local information spectrotemporal context reduce...

In order to adapt channel variation and maximize throughput performance, Adapt Modulation Coding (AMC) is used in Long-Term Evaluation (LTE) downlink. However, due the wireless random variation, inaccurate reported Channel Quality Indicator (CQI) introduced, which will affect quality of data transmission. Therefore, it necessary modify CQI AMC process. Although this paper adopts a traditional correction algorithm, ignores influence great deviation burst noise. To overcome these shortages, an...

Non-orthogonal multiple access (NOMA) is a promising technique that can dramatically increase radio resource utilization efficiency and network capacity of 5G networks. However, due to the non-orthogonal sharing among concurrent users, deployment NOMA relies on effective cancellation inter-user interference recovery superimposed signals from users. To mitigate Euclidean distance signals, two-dimensional (2D-NOMA) scheme proposed in this paper by collaborative design power-domain code-domain...
