Development discourses of the low human development index : countries in UN post-2015 discussion
2015
This study is about development discourses and agents of the countries with low Human Development Index (HDI) in Africa. It is based on six UN Post-2015 national consultations. These six nations are Burkina Faso, the Democratic Republic of Congo, Ethiopia, Mozambique, Liberia and Zambia. The criteria of data selection involve the level of HDI, language, format of the report and geographical location. The idea about development as discursive constructed social reality is at the focus of theoretical framework. The method is Discourse Analysis (DA) with some Foucauldian characteristics. The research questions are: What kind of specific development discourses and agentive roles are there in pol…
Zarys koncepcji Habermasowskiej sfery publicznej
2015
Dla Habermasa sfera publiczna jest centrum życia społeczno-politycznego. Jest ona niejako buforem między społeczeństwem a płaszczyzną władzy i polityki. Właściwy jej kształt zapewnia możliwość trafnej oceny problemów i przekazywania ich do centrów decyzyjnych władzy. Sfera publiczna jest sferą prywatnych ludzi gromadzących się w publiczność, jednak nie jako biernych widzów, ale aktywnie włączających się w definiowanie i rozwiązywanie wspólnie tematyzowanych problemów. Jej ideał Habermas upatruje w XVIII-wiecznej sferze mieszczańsko-obywatelskiej, po której jednak następuje jej rozpad. Media stają się elementem opiniotwórczym i manipulującym publicznością.
Doing change and continuity: age identity and the micro–macro divide
2009
ABSTRACTThis paper is a study of the discursive management of notions of change andcontinuity in interview talk. It presents selected short empirical examples frominterviews with 22 Finnish baby-boomers, and discusses the methodological andtheoretical issues that arise. Following a review of the major approaches to thestudy of age identity, the analytic intersection between qualitative gerontologyand discursive psychology is explored. The analysis identifies how the frequentuse of a ‘provisional continuity device’ enables speakers simultaneously both toacknowledge and to distance themselves from factual notions of physical orpsychological lifespan change. The key methodological argument is t…
On the Intrinsic Complexity of Learning
1995
AbstractA new view of learning is presented. The basis of this view is a natural notion of reduction. We prove completeness and relative difficulty results. An infinite hierarchy of intrinsically more and more difficult to learn concepts is presented. Our results indicate that the complexity notion captured by our new notion of reduction differs dramatically from the traditional studies of the complexity of the algorithms performing learning tasks.
Error detecting in inductive inference
1995
Several well-known inductive inference strategies change the actual hypothesis only when they discover that it “provably misclassifies” an example seen so far. This notion is made mathematically precise and its general power is characterized. In spite of its strength it is shown that this approach is not of universal power. Consequently, then hypotheses are considered which “unprovably misclassify” examples and the properties of this approach are studied. Among others it turns out that this type is of the same power as monotonic identification. Then it is shown that universal power can be achieved only when an unbounded number of alternations of these dual types of hypotheses is allowed. Fi…
Dual types of hypotheses in inductive inference
2006
Several well-known inductive inference strategies change the actual hypothesis only when they discover that it “provably misclassifies” an example seen so far. This notion is made mathematically precise and its general power is characterized. In spite of its strength it is shown that this approach is not of “universal” power. Consequently, then hypotheses are considered which “unprovably misclassify” examples and the properties of this approach are studied. Among others it turns out that this type is of the same power as monotonic identification. Finally, it is shown that “universal” power can be achieved only when an unbounded number of alternations of these dual types of hypotheses is all…
Topological considerations in composing teams of learning machines
1995
Classes of total recursive functions may be identifiable by a team of strategies, but not by a single strategy, in accordance with a certain identification type (EX, FIN, etc.). Qualitative aspects in composing teams are considered. For each W ∉ EX all recursive strategies can be split into several families so that any team identifying W contains strategies from all the families. For W ∉ FIN the possibility of such splitting depends upon W. The relation between these phenomena and “voting” properties for types EX, FIN, etc. is revealed.
Online Estimation of the Mechanical Parameters of an Induction Machine Using Speed Loop characteristics and Recursive Least Square Technique
2022
This paper presents a novel approach for estimation of mechanical parameters, inertia and friction coefficient of an Induction Machine (IM) using speed loop characteristics and Recursive Least Square (RLS) estimator. Using the 5th order dynamic equation for Induction Machine and the forgetting factor based RLS algorithm the technique herein proposed employs the speed of the machine and the torque as the inputs for the estimator. Results obtained compares the estimated parameters with the actual parameters under multiple step varying and exponentially varying scenarios. Upon analyzing the results, the validity and the effectiveness of the proposed identification technique is confirmed
Enhancing Speed Loop PI Controllers with Adaptive Feed-forward Neural Networks: Application to Induction Motor Drives
2022
This paper proposes the idea to improve the performance of the speed loop PI controller by using feed-forward and adaptive control actions. Indeed, when the system to be controlled is required to track a rapidly changing reference frame, higher bandwidth is usually required, making the system more sensitive to noise and consequently less robust. In such cases, to achieve a better performance in reference tracking while keeping noise rejection capacity, one idea is to use a feed-forward controller, employed to enhance the required tracking, leaving the feedback action to stabilize the system and suppress higher frequency disturbance. As such, this paper analysis the classical PI based field …
Algorithms for rational discrete least squares approximation
1975
In this paper an algorithm for the computation of a locally optimal polefree solution to the discrete rational least squares problem under a mild regularity condition is presented. It is based on an adaptation of projection methods [8], [12], [13], [14], [18], [19] to the modified Gaus-Newton method [4], [10]. A special device makes possible the direct handling of the infinitely many linear constraints present in this problem.
