Perceiving and understanding human motion is a fundamental problem in computer vision, with diverse applications encompassing sports analytics, healthcare monitoring, entertainment, and intelligent interactive systems. Multi-camera systems, by capturing multiple viewpoints simultaneously, enable robust tracking and reconstruction of human poses in 3D, overcoming limitations of single-view approach
To solve the problem of fatigue of the UAV operator during long-term search and reconnaissance missions, a research hardware and software complex was created, in which the positioning of the auxiliary UAV video camera with a narrow field of view is carried out. Dynamixel Library for MATLAB and Simulink was used to organize the interaction of actuators with the virtual environment, which allows com
Extremely thinned layers and possible folding make the dating of the deepest sections of ice cores especially challenging. Cosmogenic radionuclides have the potential to provide independent age estimates. The 36Cl/10Be ratio is largely independent of production rate changes that affect individual radionuclides and has an effective half-life of 384 kyr, making it an ideal tool for dating the new 1.
During the Last Glacial Period (LGP), Greenland experienced approximately 30 abrupt warming phases, known as Dansgaard-Oeschger (D-O) events, followed by cooling back to baseline glacial conditions. Studies of mean climate change across warming transitions reveal indistinguishable phase offsets between shifts in temperature, dust, sea salt, accumulation, and moisture source, thus preventing a comp
One of the most challenging problems in paleoclimate research is how orbital cyclicities forced Earth’s climate variations during the late Quaternary. To address this issue, we investigated the differences in silicate weathering, a sensitive climate indicator, at different latitudes on orbital timescales by examining geochemical and clay mineral data from the mid-latitude Sea of Okhotsk and integr
In this paper, we present a framework to identify discrete-time, single-input/single-output, switched linear systems (SISO-SLSs) from input–output data measurements. Continuous state is not assumed to be measured. The key step is a deadbeat observer-based transformation of the SLS model to a switched auto-regressive with exogenous input (SARX) model. Discrete states are estimated by a three-stage
Tonkilometermetoden används för beräkning av andelstal för enskilda vägar som är gemensamhetsanläggningar. Den trafikmängd som olika fastighetstyper genererar återspeglas i vissa framtagna schablonvärden. Eftersom det saknas framtagna schablonvärden för specialfastigheter såsom vindkraftverk och vattenkraftverk har jag genom detta examensarbete undersökt möjligheten att ta fram schablonvärden för The ton kilometer method is used to calculate participatory shares for private roads which is joint facility. The amount of traffic that different property types generate is reflected in certain produced templates. Because there are no templates for special properties such as wind turbines and hydroelectric plants I have investigated if it is possible to produce these types of values. I have also
This study explored the utility of the impact response surface (IRS) approach for investigating model ensemble crop yield responses under a large range of changes in climate. IRSs of spring and winter wheat Triticum aestivum yields were constructed from a 26-member ensemble of process-based crop simulation models for sites in Finland, Germany and Spain across a latitudinal transect. The sensitivit
We study transportation networks controlled by dynamical feedback tolls. We consider a multiscale transportation network model whereby the dynamics of the traffic flows are intertwined with those of the drivers' route choices. The latter are influenced by the congestion status on the whole network as well as dynamic tolls set by the system operator. Our main result shows that a broad class of dece
The spread of new beliefs, behaviors, conventions, norms, and technologies in social and economic networks are often driven by cascading mechanisms, and so are contagion dynamics in financial networks. Global behaviors generally emerge from the interplay between the structure of the interconnection topology and the local agents' interactions. We focus on the Threshold Model (TM) of cascades first
A brain-computer interface (BCI) is a real-time system that converts a user’s brain activity into commands, enabling control over applications such as moving a cursor on the screen. This conversion is made possible by machine learning techniques and other algorithms. Historically, BCI research has focused on the analysis of brain signals offline. However, increasing computational power and algorit
Silicate weathering regulates climate as a critical carbon sink, yet understanding its role in the carbon cycle is challenging because of limited knowledge about the impact of temperature and rainfall on weathering during glacial-interglacial cycles. Here we investigated the orbital scale of silicate weathering variations and their role in atmospheric carbon dioxide sequestration using reconstruct
The thermal regime is a key indicator of permafrost evolution and thaw trajectories in response to climate change but remains poorly represented in global models. In this study, we applied the Moving-Grid Permafrost Model (MGPM), an efficient numerical model, to simulate the permafrost thermal regime in West Kunlun (WKL), a 55 669 km2 region on the remote northwestern Qinghai-Tibet Plateau charact
Advances in quantum computing pose a fundamental threat to classical public-key cryptosystems, including RSA and elliptic-curve cryptography (ECC), which form the foundation for authentication and key exchange in the Transport Layer Security (TLS) protocol. In response to these emerging threats, Korea launched the KpqC (Korea Post-Quantum Cryptography) project in 2021 to design, evaluate, and stan
Fire is a pivotal aspect of human involvement in the carbon cycle. However, the precise timing of the large-scale human fire use remains uncertain. Here, we report a pyrogenic carbon record of East Asian fire history over the past 300,000 y from the East China Sea. This record suggests a rapid increase in fire activity since approximately 50,000 y ago, indicating a decoupling from the monsoon clim
Over the past 50 years, nutrient discharge into freshwater ecosystems has significantly increased due to intensive fertilizer application in China. This has led to frequent environmental issues associated with nutrient enrichment, such as algal blooms, in a number of individual lakes. However, the linkages between terrestrial nutrient sources and algal bloom occurrence (BO) at large scales remains
This letter addresses loss of packets in a wireless fronthaul link being interpreted as channel errors for the service link. This may occur if, for instance, User Equipment (UE) is served by a radio unit in an Uncrewed Aerial Vehicle (UAV) via a wireless fronthaul link to a baseband unit (BU) on the ground. The fronthaul packet loss leads to a mismatch between the real and estimated channel state,
Advances in spring phenology (SOS) and increases in terrestrial gross primary productivity (GPP) are well-documented. However, the impact of an earlier SOS on the duration and rate of carbon uptake (GPPrate) during the early growing season (EGS) remains unclear, leaving the overall influence of these factors on EGS GPP uncertain. Using satellite and carbon flux data across the Northern Hemisphere,
Single-master multi-slave (SMMS) teleoperation systems can perform multiple tasks remotely in a shorter time, cover large-scale areas, and adapt more easily to single-point failures, thereby effectively encompassing a broader range ofapplications. As the number of slave manipulators sharing a communicationnetwork increases, the limitation of communication bandwidth becomes critical. To alleviate b
