In response to the issues that existing voltage regulation methods cannot finely perceive load data within station area, have low precision, and often use active power leading high electricity costs for users, a novel intelligent method area based on multi-agent reinforcement learning is proposed. Firstly, photovoltaic (PV) output prediction technology hybrid neural network proposed predict previous day. Secondly, strategy generation mechanism integrates reactive control designed, this, an...
Abstract Altermagnetism, a newly identified class of magnetism blending characteristics both ferromagnetism and antiferromagnetism, is emerging as compelling frontier in spintronics. This study reports groundbreaking discovery robust, 100% field‐free spin‐orbit torque (SOT) switching RuO 2 (101)/[Co/Pt] /Ta structure. The experimental results reveal that the spin currents, induced by in‐plane charge current, flow along [100] axis, with polarization direction aligned parallel to Néel vector....
It has been shown that for the scheduled traffic model, connection holding time aware algorithms lead to more efficient resource allocation. The setup and teardown times of demands may be fixed, or allowed slide within a larger window. A number optimal integer linear program (ILP) solutions first problem (fixed setup/teardown times) have presented in literature, wavelength convertible networks. In this paper we present new complete ILP formulation both fixed window general sliding where vary...
We aim to save energy by scheduling periodic sensors' duty cycles. Different from existing works, we integrate two important tasks, collision avoidance and cycling, into one of activities. Our scheme consists parts: a <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">coloring scheme</i> that assigns "color" each sensor xmlns:xlink="http://www.w3.org/1999/xlink">color associates color with schedule. Each switches between sleep active modes according...
In the scheduled traffic model, design problem is to allocate resources a set of demands whose setup and teardown times are known in advance. A number integer linear program (ILP) solutions for this have been presented literature. paper we present new ILP formulation routing wavelength allocation, under model that minimizes congestion network. We propose two levels service, where idle backup can be used carry low priority traffic, fault-free conditions. When fault occurs, path need...
In hierarchical sensor networks, higher powered relay nodes can be deployed to act as cluster heads. The lifetime of such a network is primarily determined by the nodes. Recently, it has been shown that use Mobile Data Collector (MDC), which moves through collect data, improve performance in number ways. We propose model for networks using MDC, where MDC travels along pre-determined trajectory at known speed, and collects data from each node. this model, need buffer their until they uploaded...
Zr oxide coatings were deposited using plasma electrolytic oxidation (PEO) on Zr-2.5wt%Nb (Zr-2.5Nb)alloy, which is currently used for pressure tubes in the CANDU nuclear reactor.The effects of two PEO processing factors, electrolyte concentration and current density, microstructure properties systematically investigated.The coating morphology chemical composition determined scanning electron microscopy (SEM) energy dispersive X-ray analysis (EDX).Potentiodynamic polarization corrosion...

The need for powerful computing resources as well capabilities storage and transmission of large amounts data in a number application areas have led to the emergence optical grids natural, cost-effective platform supporting such applications. As result there is also an increasing strategies techniques designed achieve fault tolerance grid networks. Design both networks are mature, well-researched fields their own right. However, survivability should not be treated merely concatenation...
Multi-view stereopsis (MVS) recovers 3D surfaces by finding dense photo-consistent correspondences from densely sampled images. In this paper, we tackle the challenging MVS task sparsely views (up to an order of magnitude fewer images), which is more practical and cost-efficient in applications. The major challenge comes significant correspondence ambiguity introduced severe occlusions highly skewed patches. On other hand, such can be resolved incorporating geometric cues global structure....

However, many current studies combination two simply treat microservices replacement for traditional virtual machine without fully...
We investigate the magnetic and electronic properties of Co films on Fe3O4(001) achieved through epitaxial growth using magnetron sputtering. X-ray circularly dichroism measurements characterize atomic magnetism. Compared to MgO substrate, Fe3O4 exhibits a 96% enhancement in orbital moment (from 0.25 0.49 µB/atom) an increase spin 1.37 1.53 µB/atom), resulting increased mratio(ml/ms) from 0.18 0.32. This emerges as consequence interface interaction between Fe3O4. Density functional theory...
Abstract In this study, deterministic current‐induced spin‐orbit torque (SOT) magnetization switching is achieved, particularly in systems with perpendicular magnetic anisotropy (PMA), without the need for a collinear in‐plane field, traditionally challenging requirement. Ta/CoFeB/MgO/NiO/Ta structure, spin reflection at MgO/NiO interface generates current an out‐of‐plane polarization component σ z . Notably, sample featuring 0.8 nm MgO and 2 NiO demonstrates impressive optimal ratio...
Multifibre optical networks use a bundle of fibres to realize link between two nodes. Such can offer significant economic benefits over single-fibre because their ability relax the restrictions imposed by wavelength continuity constraint and potential for handling future growth. This paper introduces new efficient integer linear program (ILP) formulations dynamic allocation in survivable multifibre wavelength-division multiplexing (WDM) networks, using dedicated shared protection....
When deploying radio frequency (RF)-powered sensor networks for mission-critical applications such as security surveillance, it is often required to maximize or guarantee the quality of surveillance. Both placing and scheduling charging/working modes sensors are key importance in order continuously ensure a satisfying Traditionally, placement have been considered separately. The first decision regards where place sensors, then when activate them. In this paper, we study simultaneous problem...
