Проведено исследование влияния термической, термомеханической и аэроакустической обработок на формирование структуры и механических свойств сплава БрБ2 (прутки, тянутые после закалки). Анализ результатов исследований свойств сплава после указанных обработок по оптимизированным режимам показал, что аэротермоакустическая обработка, предшествующая старению сплава, обеспечивает повышение условного предела текучести без снижения пластичности, а также повышение теплостойкости сплава БрБ2. Уровень значений условного предела текучести превосходит величину этого параметра у сплава БрБ2,5.

Abstract: This paper explores a data-driven method to investigate the stabilization of intermittent controlled discrete-time systems (ICDTSs) with unknown parameter matrices. First, the pre-collected inputstate data is used to supersede the accurate prior system model. Then, in order to obtain the data-dependent stabilization conditions of ICDTSs, a novel relationship is designed among the control width, rest width, and convergence rate. Unlike existing studies on the stabilization of ICDTSs, this paper only needs the collected input-state data. Thus, the time-consuming process of model identification is avoided. In addition, to ensure an acceptable performance level, the data-based guaranteed cost control is also considered, and a new cost function for ICDTSs is correspondingly built. Finally, two simulations are presented to demonstrate the effectiveness of the theoretical analysis.

Abstract: As an optimization technique, the gradient descent method is widely adopted in the training process of deep learning. In traditional gradient descent methods, the gradient of each dimension has the same weight wtih the updating direction, which results in poor performances when there are multiple small gradient dimensions (e.g. near the saddle point). To improve the accuracy and convergence speed of the neural network training, we propose a novel multi-dimensional adaptive learning rate gradient descent optimization algorithm (M-AdaGrad) in this paper. Specifically, in the M-AdaGrad, the learning rate will be updated according to a newly designed weight function related to the current gradient. Experiments on a set of sigmoid-based functions verify that, compared with traditional gradient descent methods such as AdaGrad and Adam, the M-AdaGrad gives more confidence to the larger gradient direction and has a larger probability to reach a more optimal position with a faster speed. Due to its excellent performance in network training, the M-AdaGrad is successfully applied to the magneto-optical nondestructive test of crack detection based on the generative adversarial network.

Abstract: Adaptive control is an effective approach for mitigating undesirable deviations in prescribed closed-loop plant behavior. However, conventional adaptive control methods often exhibit slow responses in various control tasks. This paper introduces a novel adaptive control method to achieve fixed-time synchronization in a class of coupled neural networks. We present coupled neural networks with multiple switching topologies and design a fixed-time adaptive control strategy for this system. Furthermore, we establish a criterion to ensure the fixed-time stability of the closed-loop system. Two numerical examples are provided to demonstrate the effectiveness and accuracy of the theoretical results.
Nguemisme. Les dictadures de Macías Nguema i Teodoro Obiang a Guinea Equatorial: continuïtats i ruptures (1968-2023)
Authors: Nerín Abad Gustau 
Published: September 2024

Aquest article tracta d'aclarir les semblances i diferències entre les dues dictadures postcolonials de Guinea Equatorial: la de Macías Nguema (1968-1979) i la de Teodoro Obiang (a partir de 1979). Alguns estudiosos i opositors les han englobat sota el terme “nguemisme”, to considerant-les un mateix règim, ja que Teodoro Obiang pertany al mateix clan que Macías, va ser un alt càrrec macista i va incorporar al seu Govern nombrosos quadres de la dictadura de Macías. Tanmateix, i per molt que tots dos règims es caracteritzen per alts nivells de repressió, hi ha diferències substancials entre tots dos. No sols van adoptar posicions diferents en política exterior (el règim de Macías es va aproximar als No Alineats i el d'Obiang va col·laborar més amb Occident), sinó que també van mantenir relacions diferents amb els grups de poder del país. En tant que el macisme es va enfrontar als caps tradicionals, a l'Església, als poders econòmics i als quadres formats a Europa, Obiang va preferir col·laborar-hi, per bé que sotmetent-los al seu control; i això li ha permès exercir el poder amb menors dosis de repressió.

Authors: Melo Filho Cícero Rodrigues de , Castro João Carlos Parkinson de 
Published: September 2024

O processo de integração da América do Sul pode ser analisado sob diferentes dimensões: política, econômica, energética, cultural, comercial e física. O corredor bioceânico permitirá que estados brasileiros sem acesso ao mar, como Mato Grosso do Sul, e, também, o Chaco paraguaio acessem os portos do Pacífico de forma eficiente. Esse trabalho mostra que o Corredor reduzirá os custos logísticos e o tempo de viagem, resultando no aumento da competitividade dos produtos de Brasil, Paraguai, Argentina e Chile. Os produtores desses países serão mais competitivos no Sudeste Asiático, pois o corredor fornecerá serviços de transporte e logística mais eficientes. Além disso, o transporte rodoviário estimulará o fluxo de comércio com maior valor agregado, atrairá novos investimentos comerciais e induzirá novas parcerias, assim como melhorias contínuas nos sistemas de transporte.

Nutka 1789. Un proyecto evangelizador frustrado
Authors: PALOMARES SÁNCHEZ BÁRBARA 
Published: September 2024

A finales del XVIII, los derechos territoriales españoles en el Pacífico norte comenzaron a ser cuestionados. Los rumores sobre la presencia rusa y la posibilidad de que tuvieran un establecimiento permanente en aquellas aguas con el fin de comerciar con las pieles de nutria, llevó a la Corona española a organizar una serie de expediciones, entre los años 1774-1789. Tras confirmar las sospechas, en 1789, se arma una nueva expedición hacia Nutka con las siguientes instrucciones: reafirmar la soberanía española, establecer un asentamiento permanente y llevar la fe católica hasta aquellas tierras. Con este fin, cuatro misioneros franciscanos seleccionados por el Colegio de San Fernando de México se embarcaron en esta expedición para tratar de cumplir con su cometido misional.
Abstract: At the end of the 18th century, Spanish territorial rights in the North Pacific began to be questioned. Rumors about the Russian presence and the possibility that they had a permanent establishment in those waters in order to trade in otter skins, led the Spanish Crown to organize a series of expeditions, between the years 1774-1789. After confirming the suspicions, in 1789, a new expedition to Nutka was armed with the following instructions: reaffirm Spanish sovereignty, establish a permanent settlement and bring the Catholic faith to those lands. To this end, four Franciscan missionaries selected by the Colegio de San Fernando de México embarked on this expedition to try to fulfill their missionary mission.

"Bárbora escrava": Canon, beauty and color: An embarrassing contradiction
Authors: Marnoto Rita 
Published: September 2024

Abstract: The Petrarchan literary canon revered white-skinned, fair-haired women, and this model held sway over all European literature. Camões respectfully followed it in most of his poetic works. However, he dedicated a poem, in which love is presented as an extremely gratifying experience, to a black slave, Bárbora, and it is usually considered among his most beautiful poems. The representation of beauty and happiness in Bárbora entails an association of problematic factors that has received a great deal of commentary throughout the centuries. This article focuses on these readings in the light of “mimicry” as conceived by Homi Bhabha.
