Feature-point extraction is a fundamental step in many applications, such as image matching and Simultaneous Localization Mapping (SLAM). The CNN-based feature-point methods have made significant signs of progress both detection descriptor generation compared with handcrafted processes. However, the computational storage complexity makes it difficult for CNN to run on real-time embedded systems. In this paper, we aim deploy advanced onto FPGA We optimize softmax data flow so that computation...
To meet the evolving data rate requirements of emerging wireless communication technologies, many parallel architectures have been proposed to implement high throughput turbo decoders. However, concurrent memory reading/writing in decoding leads severe conflict problem, which has become a major bottleneck for In this paper, we propose flexible and efficient VLSI architecture solve problem highly decoders targeting multi-standard 3G/4G systems. demonstrate effectiveness interleaver...
Subjective well-being has a significant impact on an individual's physical and mental health. Socioeconomic status, class identity, social activity participation play important roles in subjective well-being. Therefore, the aim of this study was to uncover mechanisms through which these factors influence well-being.A total 1926 valid samples were recruited using Chinese General Social Survey 2021 (CGSS 2021). The Citizen's Well-Being Scale (SWBS-CC) employed assess status measured income...
Introduction This study, based on Volunteered Geographic Information (VGI) and multi-source data, aims to construct an interpretable macro-scale analytical framework explore the factors influencing urban physical activities. Using 290 prefecture-level cities in China as samples, it investigates impact of socioeconomic, geographical, built environment both overall activity levels specific types mobile Methods Machine learning methods were employed analyze data systematically. Socioeconomic,...
As an efficient management pattern to improve logistics efficiency through intensive of construction materials, centers (CLCs) have received active attention from academics and practitioners. However, the CLC location–allocation problem, which considers periodic demand transportation risk, has not been adequately solved. This work provides approach integrating path risk into multiperiod optimization for large-scale projects in complex environmental regions. For this purpose, paper formulates...
The genetic structure of populations is often shaped by processes and events that introduce asymmetries to gene flow between geographic locations. Existing population methods like EEMS FEEMS summarize using effective equilibrium migration rates are assumed be symmetric, providing representations underlying have proven useful, but fall short representing signatures asymmetric flow. More elaborate capable inferring exist, computationally intensive, restricting analyses small sets...
We propose the use of time-varying (TV) signaling in modulation schemes to provide multiuser detection and multipath diversity TV wireless channels. Specifically, we design an orthogonal linear chirp scheme that is based on assigning different users with optimally designed parameters order reduce multiple-access interference. also derive conditions signals achieve diversity. Furthermore, pilot nonlinear instantaneous frequency matched time-frequency (TF) techniques estimate fast-fading...
ABSTRACT The optimization of park green space landscape pattern is great significance to the construction an ecological civilized city. Through a case study national garden city – Mianyang City, Sichuan Province and with help analysis softwares such as ENVI ArcMap, public in central urban area has been quantitatively analyzed terms Normalized Vegetation Difference Index (NVDI) index, corresponding strategies have proposed. It found out that: 1. NVDI Fucheng District presents growing trend...
This paper presents a comprehensive analysis of the outage probability for multiple-input-multiple-output (MIMO) systems with receive antenna selection. In this analysis, it is assumed that 1) given M antennas, receiver selects best L antennas maximize capacity, 2) channel state information perfectly known at receiver, but not transmitter, 3) subchannels fade independently, and 4) fading coefficients change very slowly such averaging respect to these possible. Under assumptions, two upper...

Our methodology uses the matched signal transform is highly localized signals nonlinear phase along their frequency-modulation (FM) rate. compare this method use of more computationally intensive quadratic time-frequency representations whose performance reduced when multicomponent.
In this paper, implementation of a detector with parallel partial candidate-search algorithm is described. Two fully independent candidate search processes are simultaneously employed for two groups transmit antennas based on QR decomposition (QRD) and QL (QLD) multiple-input multiple-output (MIMO) channel matrix. By using separate simultaneous searching processes, the proposed QRD-QLD searching-based sphere provides smaller latency lower computational complexity than original QRD-M similar...
