Speaker normalization may have a significant impact on both speakeradaptive and speaker-independent speech recognition. In this paper, a codeworddependent neural network (CDNN) is presented for speaker normalization. The network is used as a nonlinear mapping function to transform speech data between two speakers. The mapping function is characterized by two important properties. First, the ass...

Abstract It follows from Michael’s selection theory that a closed convex nonempty-valued mapping the Sorgenfrey line to euclidean space is inner semicontinuous if and only can be represented as image closure of right-continuous selections mapping. This article gives necessary sufficient conditions for representation hold càdlàg selections, i.e., are have left limits. The characterization motiva...

Ecosystems provide services necessary for the livelihoods and well-being of people. Quantifying and mapping supplies and demands of ecosystem services is essential for continuous monitoring of such services to support decision-making. Area-wide and spatially explicit mapping of ecosystem services based on extensive ground surveys is restricted to local scales and limited due to high costs. In c...

A function f is continuous iff the pre-image f[V ] of any open set V is open again. Dual to this topological property, f is called open iff the image f [U ] of any open set U is open again. Several classical Open Mapping Theorems in Analysis provide a variety of sufficient conditions for openness. By the Main Theorem of Recursive Analysis, computable real functions are necessarily continuous. I...

In this note we show the spectral mapping theorem for the evolution semigroup on L p ((; ; X), 1 p < 1, associated with a strongly continuous cocycle on a Banach space over a continuous ow on a locally compact metric space.

Persistence of applications written in an object-oriented language using a relational storage system has been investigated for a long time [4]. In this paper, two problems of current approaches to objectrelation mapping are addressed. First, their high configuration effort, and second, their lacking support for continuous development. To address these problems, we introduce a novel object-relat...

Let Z andX be Banach spaces, U ⊂ Z be an open convex set and f : U → X be a mapping. We say that f is a d.c. mapping if there exists a continuous convex function h on U such that y ◦ f + h is a continuous convex function for each y ∈ Y , ‖y∗‖ = 1. We say that f : U → X is locally d.c. if for each x ∈ U there exists open convex U ′ such that x ∈ U ′ ⊂ U and f |U ′ is d.c. This notion of d.c. map...

The notions of compact convex variation and compact convex subdifferential for the mappings from a segment into a locally convex space (LCS) are studied. In the case of an arbitrary complete LCS, each indefinite Bochner integral has compact variation and each strongly absolutely continuous and compact subdifferentiable a.e. mapping is an indefinite Bochner integral. 0. Introduction and prelimin...

We prove the following result. Let C be a convex compact subset in a topological vector space, and T : C → C a convex continuous mapping. (See Definition 1.1.) Then T has a fixed point. Moreover, continuous mappings that can be approximated by convex continuous mappings also have the fixed point property.

best approximation results provide an approximate solution to the fixed point equation $tx=x$, when the non-self mapping $t$ has no fixed point. in particular, a well-known best approximation theorem, due to fan cite{5}, asserts that if $k$ is a nonempty compact convex subset of a hausdorff locally convex topological vector space $e$ and $t:krightarrow e$ is a continuous mapping, then there exi...
