Subject:
Simone de Beauvoir, The Second Sex, debate, Czechoslovakia, feminism, and state socialism
Language:
Czech
Description:
Simone de Beauvoir’s Th e Second Sex was translated into Czech in 1966, the fi rst translation of the book to be published in a socialist state. It was, like many other translations during this period, a compilation of selections and was edited by the phenomenologist Jan Patočka who, in his postscript, presented the work primarily within its philosophical context. Th e book, which was published in three editions within two years and reached a combined print run of almost one hundred thousand copies, reaped substantial acclaim both among the lay and the academic public. Th e main debate about the book unfolded in the magazines Literární noviny and Vlasta, in which the contributors aired their views on the book from various positions – as advocates of phenomenology, Marxism, and the women’s press.

Subject:
historiography and Czech-Slovak relations
Language:
English
Description:
This article focuses on the early post-1989 period when the ''Slovak question'' returned with full force to the gradually democratizing political arena and surprised Czech society and its budding political elite, who were both unprepared to address the question. The author reveals the imbalance of ''Czechoslovakism'' - its story and historical lesson - between the two sides of the once united country. In Slovakia, Czechoslovakism was ''part of the living language of politics and journalism of the Slovak experience,'' whilst in Czech society, its reception was lukewarm and superfi cial. Thanks to his insight into federal and republican politics in the early days of democratic revival, the author presents his readers with a fascinating breakdown of the factual-historic presence of Czechoslovakism at a time when its word-historical presence was minimal. He analyzes how Slovakia stepped into democracy by exercising its national sovereignty in federal structures and played as active a role as ever in Czech-Slovak relations. Meanwhile, the Czech side remained merely reactive. In contrast to the Slovak scene, Czechs were engaged in a ''politics of returns,'' buttressed by a resolutely idealized image of the First Republic and a renewed spirit of ''Czechoslovakness,'' which was deceptively refreshing for Czech society. These were two political worlds, able to fi nd a common denominator only with great effort. The author explains that Czech politics were de facto forced - by the Slovaks, who were developing federal principles and creating policies for national sovereignty - into lackluster policy-making of their own national sovereignty. Even so, these forced politics had their advocates, such as national-socialist politicians in the Czech National Council at that time. and Překlad Tereza Jonášová a Kathleen Geaney

Description:
The essential point for seismological observation in the northern part of Moravia, Czech Republic, is a permanent seismic station Ostrava - Krásné Pole (OKC) that is a part of the Czech regional seismological network (hereafter CRSN). Institute o f Geonics AS CR, v.v.i., has also operated temporary seismic stations in this region since 1997. Current seismological stations are located in an abandoned mine working located in Zlaté Hory and in cellars in Klokočov and castle Raduň near Opava. The natural seismicity is after the swarm of microearthquakes in the vicinity of Opava in 1993 very low now. In region under discussion, seismic manifestations generated by mining induced seismicity in Upper Silesian Coal Basin (both Karviná an d Polish parts) and in Legnica-Głogów Copper District (LGOM) are also detected. Significant part of observations in this region is made by the Institute of Physics of the Earth (hereafter IPE), Masaryk University Brno, and about 1000 microearthquakes have been detected during the last ten years with maximum local magnitude up to 1.9., Zdeněk Kaláb, Jaromír Knejzlík and Karel Holub., and Obsahuje bibliografické odkazy

Language:

Description:
The decay of tyrosine cation radical was found to be biphasic at 253 K. The fast phase corresponds to the YZ* component while the slow phase corresponds to the tyrosine D radical (YD*) component. At 253 K, the t1/2 value was ∼28.6 s for the fast phase and ∼190.7 s for the slow phase. The fast phase is attributed to the recombination of charges between YZ* and QA-. The activation energy for the reaction of YZ with QA- between 253 and 293 K was 48 kJ mol-1 in Cl--depleted photosystem 2 (PS2) membranes. Both the decay rate and the amplitude of the PAR-induced signal of YZ* were affected by addition of chloride anion. Change in the decay rate and the amplitude of the PAR-induced signal of YZ* was observed when other anions like Br-, I-, F, HCO3-, NO3-, PO43- were substituted in the Cl--depleted PS2. and A.

Format:

Type:
model:article and TEXT
Subject:
decentralized control, complex dynamical network, similarity, stabilization, and synchronization
Language:
English
Description:
A new class of controlled time-varying complex dynamical networks with similarity is investigated and a decentralized holographic-structure controller is designed to stabilize the network asymptotically at its equilibrium states. The control design is based on the similarity assumption for isolated node dynamics and the topological structure of the overall network. Network synchronization problems, both locally and globally, are considered on the ground of decentralized control approach. Each sub-controller makes use of the information on the corresponding node's dynamics and the resulting overall controller is composed of those sub-controllers. The overall controller can be obtained by means of a combination of typical control designs and appropriate parametric tuning for each isolated node. Several numerical simulation examples are given to illustrate the feasibility and the efficiency of the proposed control design.

5879. Decentralized control for large-scale systems with itme-varying delay and unmatched uncertainties

Subject:
decentralized variable structure control, uncertain large-scale systems, time-delayed systems, and unmatched uncertainty
Language:
English
Description:
Many real-world systems contain uncertainties and with time-varying delays, also, they have become larger and more complicated. Hence, a new decentralized variable structure control law is proposed for a class of uncertain large-scale system with time varying delay in the interconnection and time varying unmatched uncertainties in the state matrix. The proposed decentralized control law for the large-scale time-varying delay system is realized independently through the delayed terms and it can drive the trajectories of the investigated systems onto the sliding mode. Further, the proposed control law can be successfully applied to stabilize a class of uncertain large-scale time-varying delay system with matched and unmatched uncertainties. The so-called sliding coefficient matching condition can be extended for the decentralized variable structure control of the uncertain large-scale time-varying delay systems. Furthermore, in the sliding mode, the investigated system with matched and unmatched uncertainties still bears the insensitivity to the uncertainties and disturbances, which is the same as the systems with just matched uncertainties do. Finally, an illustrative example is given to verify the validity of the proposed decentralized variable structure control law. It has been shown that the proposed decentralized control law is effective for all subsystems of the investigated system. However, the traditional decentralized variable structure control law is not applicable to the investigated system with unmatched uncertainties. It is worth noting that the traditional large-scale system is only a special case in this work.

5880. Decentralized output regulation of large scale nonlinear systems with delay

Creator:

Type:
model:article and TEXT
Subject:
decentralized control, output regulaton, nonlinear systems, and time delay
Language:
English
Description:
This paper deals with output regulation of a class of large-scale nonlinear systems with delays. Each of the subsystems is in the output feedback form, with nonlinear functions of the subsystem output and the outputs of other subsystems. The system outputs are subject to unknown constant delays. Both the system dynamics and the measurements are subject to unknown disturbances generated from unknown linear exosystems. Decentralized control design approach is adopted to design local controllers using measurements or regulated errors in each subsystems. It is shown in this paper that delays in the outputs of subsystems do not affect the existence of desired feedforward control input, and the invariant manifolds and the desired feedforward inputs always exist if the nonlinear functions are polynomials. Through a special parameterization of an augmented exosystem, an internal model can be designed for each subsystem, without the involvements of the uncertain parameters. The uncertain parameters affected by the uncertainty of the exosystem are estimated using adaptive control laws, and adaptive coefficients in the control inputs are used to suppress other uncertainties. The proposed decentralized adaptive control strategy ensures the global stability of the entire system, and the convergence to zero of the regulated errors. An example is included to demonstrate the proposed control strategy.
