1384. Adaptace krušnohorského lidového domu na klimatické podmínky

Creator:
Riezner, Jiří
Format:
bez média and svazek
Type:
model:article and TEXT
Subject:
adaptation, cold climate, vernacular architecture, and Ore Mountains folk house
Language:
Czech
Description:
The article deals with the forms of the adaption of vernacular buildings situated in the upper part of the Ore Mountains to cold climate. Unfavourable climatic conditions in the mountainous areas were a significantly restricting factor, especially in terms of agriculture and permanent settlement. The Ore Mountains folk house is a result of the century-long adaptation to cold climate, and as such it includes a set of purposeful measures. These could be seen in the layout and construction of the house (a compact house with integrated shed, specific forms of roof) and materials used (boarding or shingle-panelling to protect gables and half-timbered walls, shingle or thatch roofs). Different architectural elements, which were conditioned by the local climate and were typical for the traditional architecture in the Ore Mountains, developed there (wind porch, bay toilet, another entrance on the second floor).

1385. Adaptace přesídlenců z Malinovky a Malé Zubovštiny v Milovicích

Type:
model:article and TEXT
Subject:
return migration, re-settlement, adaptation, identity, Ukraine, and former Soviet Union
Language:
Czech
Description:
The present text maps the actual situation of the participants of the controlled resettlement from the former Soviet Union to the Czech Republic in the years 1992–1993. Better to say, it maps the situation of a group of these settlers who at present live in the village Milovice, in the revitalized former military domain in the south-eastern part of the region Střední Čechy (Central Bohemia). The aim of the research was to analyze how the settlers perceive their reception from part of the majorite society, to study their adaptive strategies and to find out if the resettlement to the Czech Republic and the choice of the mentioned locality fulfilled their wishes and to what degree. The final part of the article summarizes what the settlers see as positive and what as negative aspects of the resettlement. The text is based on repeated directed interviews and observations realized in Milovice in the years 2008–2009.

Language:
English
Description:
We hypothesized that hypertension-related myocardial remodeling characterized by hypertrophy and fibrosis might be accompanied by cell-to-cell gap junction alterations that may account for increased arrhythmogenesis. Intercellular junctions and expression of gap junction protein connexin-43 were analyzed in rat heart tissues from both spontaneous (SHR) and L-NAME model of hypertension. Isolated heart preparation was used to examine susceptibility of the heart to lethal ventricular fibrillation induced by low potassium perfusion. Ultrastructure observation revealed enhanced neoformation of side-to-side type while internalization of end-to-end type (intercalated disc-related) of gap junctions prevailed in the myocardium of rats suffering from either spontaneous or L-NAME-induced hypertension. In parallel, immunolabeling showed increased number of connexin-43 positive gap junctions in lateral cell membrane surfaces, particularly in SHR. Besides, focal loss of immunopositive signal was observed more frequently in hearts of rats treated with L-NAME. There was a significantly higher incidence of hypokalemia-induced ventricular fibrillation in hypertensive compared to normotensive rat hearts. We conclude that adaptation of the heart to hypertension-induced mechanical overload results in maladaptive gap junction remodeling that consequently promotes development of fatal arrhythmias., M.

1387. Adaptation strategies of two leaf cohorts of Prosopis juliflora produced in spring and monsoon

Description:
Prosopis juliflora is an invasive leguminous tree species growing profusely under wide environmental conditions. Primary objective of this study was to investigate adaptation strategies evolved to deal with wide environmental conditions during different seasons. P. juliflora adapts through a production of leaves in two seasons, namely, the spring (the first cohort) and monsoon (the second cohort) with differing but optimal physiological characteristics for growth in respective seasons. Our studies show that the first cohort of leaves exhibit maximum carbon fixation under moderate temperatures and a wide range of PPFD. However, these leaves are sensitive to high leaf-to-air-vapor pressure deficit (VPD) occurring at high temperatures in summer resulting in senescence. While the second cohort of leaves produced during monsoon showed maximum carbon fixation at high irradiance and temperatures with low VPD, it is sensitive to low temperatures causing senescence in winter., P.

1388. Adaptive control of uncertain nonholonomic systems in finite time

Format:

Type:
model:article and TEXT
Subject:
finite-time convergence, parameter uncertainty, adaptive control, and nonholonomic systems
Language:
English
Description:
In this paper, the finite-time stabilization problem of chained form systems with parametric uncertainties is investigated. A novel switching control strategy is proposed for adaptive finite-time control design with the help of Lyapunov-based method and time-rescaling technique. With the proposed control law, the uncertain closed-loop system under consideration is finite-time stable within a given settling time. An illustrative example is also given to show the effectiveness of the proposed controller.

1389. Adaptive finite-time synchronization of cross-strict feedback hyperchaotic systems with parameter uncertainties

Creator:

Format:

Type:
model:article and TEXT
Subject:
finite-time synchronization, cross-strict feedback hyperachaotic system, backstepping, and adaptive control
Language:
English
Description:
This paper is concerned with the finite-time synchronization problem for a class of cross-strict feedback underactuated hyperchaotic systems. Using finite-time control and backstepping control approaches, a new robust adaptive synchronization scheme is proposed to make the synchronization errors of the systems with parameter uncertainties zero in a finite time. Appropriate adaptive laws are derived to deal with the unknown parameters of the systems. The proposed method can be applied to a variety of chaotic systems which can be described by the so-called cross-strict feedback systems. Numerical simulations are given to demonstrate the efficiency of the proposed control scheme.

1390. Adaptive neuro-fuzzy inference system with second order Sugeno consequents

Type:

Subject:
ANFIS, Substractive clustering, Sugeno fuzzy inference systems, and fuzzy modeling
Language:
English
Description:
Adaptive Neuro-Fuzzy Inference System (ANFIS) with first order Sugeno consequent is used widely in modeling applications. Though it has the advantage of giving good modeling results in many cases, it is not capable of modeling highly non-linear systems with high accuracy. In this paper, an efficient way for using ANFIS with Sugeno second order consequents is presented. Better approximation capability of Sugeno second order consequents compared to lower order Sugeno consequents is shown. Subtractive clustering is used to determine the number and type of membership functions. A hybrid-learning algorithm that combines the gradient descent method and the least squares estimate is then used to update the parameters of the proposed Second Order Sugeno-ANFIS (SOS-ANFIS). Simulation of the proposed SOS-ANFIS for two examples shows better results than that of lower order Sugeno consequents. The proposed SOS-ANFIS shows better initial error, better convergence, quicker convergence and much better final error value.
