In this paper we prove that over local or global fields of characteristic 0, the Corestriction Principle holds for kernel and image of all maps which are connecting maps in group cohomology and the groups of R-equivalences. Some related questions over arbitrary fields of characteristic 0 are also discussed. AMS Mathematics Subject Classification (1991): Primary 11E72, Secondary 18G50, 20G10 Pla...

During fi nancial crises central banks usually decrease interest rates in order to reduce fi nancial uncertainty. This behavior increases infl ation risk. The trade-off between infl ation and uncertainty stabilization can be modeled by the generalized Taylor rule, which describes infl ation sensitivity as a function of fi nancial uncertainty instead of a constant parameter. Based on the GMM-est...

We introduce the notion of localized topological pressure for continuous maps on compact metric spaces. The localized pressure of a continuous potential φ is computed by considering only those (n, ε)separated sets whose statistical sums with respect to an m-dimensional potential Φ are ”close” to a given value w ∈ R. We then establish for several classes of systems and potentials φ and Φ a local...

In this paper, we apply and enhance the i-vector-PLDA paradigm to text-dependent speaker recognition. Due to its origin in text-independent speaker recognition, this paradigm does not make use of the phonetic content of each utterance. Moreover, the uncertainty in the i-vector estimates should be taken into account in the PLDA model, due to the short duration of the utterances. To bridge this g...

We examined factors that affect the propagation of error in analyses of land-cover change classified from multi-temporal satellite imagery by simulating multiple versions of land-cover maps at two times, time-1 and time-2. The maps, each with two categories of land-cover, were produced to investigate three specific attributes that affect change-detection accuracy: (1) the pattern of change that...

یکی از مسائلی که در سیستم sar مطرح می شود مسأله نویز speckle می باشد. منبع تولید نویز speckle فاز نسبی پراکنده گرهای مختلف در یک سلول رادار می باشد که نوسانات شدیدی در سیگنال دریافتی به وجود آورده و تصویر حاصل را دانه دانه می نماید. این نویز تفسیر تصاویر را مشکل و اطلاعات زیادی را مخفی می کند و لذا کاهش آن یکی از ملزومات در پردازش سیگنال sar است. الگوریتمهای متعددی جهت کاهش نویز speckle در نوا...

The evaluation of the exploration risk in the oil industry is a fundamental component of the decision process related to the exploratory phase. In this paper the two basic components of the exploratory risk: trap geometry and trapped hydrocarbon quantities (fluid), are compounded in a single coherent uncertainty and sensitivity approach. The results clarify that the model geometry influences ea...

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

In this paper we consider problem of exploration and mapping of unknown polygonal environments. To construct a map of unknown environment we first must have exploration algorithm, and we have to choose a map representation method. Unknown environment needed to be explored is an indoor office environment. We use line map representation method since it is easy to represent office environment usin...

The aim of this paper is to outline a proposed project to holistically generalise spatial data using agents. Cartographic generalisation is a process that is fraught with uncertainty – for a particular spatial scale there are an infinite amount of combinations for the display (or non-display) of data in the map space. Each map element (e.g. objects such as roads or buildings can be map elements...
