Avaliação de uma Unidade de Geração de Energia Através da Teoria de Opções Reais by Alexandre Caporal, Luiz Eduardo Teixeira Brandão

“…Em função disso, a Agência Nacional de Energia Elétrica (ANEEL) tem oferecido uma multiplicidade de oportunidades de investimentos, principalmente através de leilões de unidades geradoras de energia (em sua maioria hidrelétricas), de linhas de transmissão e incentivos ao investimento em Pequenas Centrais Hidrelétricas (PCH). Neste artigo, propomos um modelo de avaliação de uma unidade de geração de energia em condições de incerteza, incorporando a flexibilidade de escolha do mecanismo de venda da energia gerada através da metodologia das Opções Reais, e aplicamos este modelo ao caso de uma PCH. …”

Theoretical Analysis of Mining Induced Overburden Subsidence Boundary with the Horizontal Coal Seam Mining by Weitao Yan, Junjie Chen, Yi Tan, Wenzhi Zhang, Lailiang Cai

“…For bedrock, the results show that the subsidence boundary of bedrock is 1/4 of the wavelength of pressure wave from the mining boundary, strata subsidence boundary expands with the increase of vertical distance between calculated strata and coal seam, and the subsidence boundary in bedrock is an upward concave curve. For unconsolidated stratum, the results show that the larger the internal friction angle, the greater the angle between subsidence boundary and horizontal line. …”

Radial Evolution of MHD Turbulence Anisotropy in Low Mach Number Solar Wind by Xingyu Zhu, Gary P. Zank, Lingling Zhao, Ashok Silwal

“…Particularly, the magnitudes of 2D and NI/slab fluctuations are comparable in the frequency domain for the modestly super-Alfvénic flow, resulting in a slightly concave shape of z ^− spectrum at 1 au. We show that, in the wavenumber domain, the power ratio of the observed forward NI/slab and 2D fluctuations is  ∼15 at 0.08 au, while it decreases to  ∼3 at 1 au, suggesting the growing significance of the 2D fluctuations as the turbulence evolves in low Mach number solar wind.…”

Robust transmission algorithm for IRS-assisted NOMA network with hardware impairments and imperfect CSI by Qilie LIU, Jiacheng FANG, Yanan XIN, Qianbin CHEN

“…To improve the robustness and reduce the energy consumption of non-orthogonal multiple access (NOMA) networks, based on hardware impairments (HWI) of transceiver and non-perfect channel state information (CSI), an intelligent reflecting surface (IRS) assisted transmission power minimization algorithm for NOMA networks was proposed.The joint optimization problem of active beam assignment at the base station and passive beam assignment at the IRS was modeled based on HWI and non-perfect CSI.The system considered the user quality of service (QoS) constraint, the serial interference cancellation constraint and the reflection phase shift constraint of the IRS.To solve this nonconvex optimization problem, the QoS constraints were firstly transformed using linear approximation and S-Procedure methods.Then the optimization problem was decomposed into two subproblems.The active beam assignment subproblem was solved using the successive convex approximation (SCA) method.The passive beam assignment subproblem was solved using the penalized convex-concave process algorithm.Finally, the final solution was obtained by iterating the subproblems alternately using alternating optimization.The simulation results show that the proposed algorithm reduces 17.05% compared to the or thogonal multiple access robust algorithm in terms of transmitted power.In terms of system robustness, the proposed algorithm improves by 20.69% and 31.14% compared to the HWI robust algorithm and the CSI robust algorithm, respectively.…”
