In this note, we investigate non-locally-convex topological vector spaces for which the closed graph theorem holds. In doing so, we introduce new classes of topological vector spaces. Our study includes a direct extension of Pták duality to the non-locally-convex situation.

the purpose of the study was to examine compliance of extension personnel in imo state agricultural extension service delivery system of nigeria. a purposive and multi-stage random sampling was used to select 105 extension personnel from the three agricultural zones of the state. data generated were analyzed using descriptive statistics such as frequencies and percentages, as well as mean score...

Let X be a Kähler manifold of complex dimension n with smooth Kähler metric ω, and Z ⊂ X a smooth complex hypersurface. Let L→ X be a holomorphic line bundle with a possibly singular Hermitian metric e−φ whose singular locus does not lie in Z, i.e., such that e|Z is a metric for L|Z . Assume also that the line bundle EZ → X associated to the divisor Z has a holomorphic section fZ such that Z = ...

In this paper we consider the (d, n)-domination number, γd,n(Qn), the distance-d domination number γd(Qn) and the connected distance-d domination number γc,d(Qn) of ndimensional hypercube graphs Qn. We show that for 2 ≤ d ≤ bn/2c, and n ≥ 4, γd,n(Qn) ≤ 2n−2d+2, improving the bound of Xie and Xu [19]. We also show that γd(Qn) ≤ 2n−2d+2−r, for 2 − 1 ≤ n − 2d + 1 < 2 − 1, and γc,d(Qn) ≤ 2n−d, for ...

In this paper, an artificial stereo extension method of speech is proposed to control the width of auditory image. The proposed stereo extension method employs a decorrelator to make stereo-channel signals without any additional information from mono speech signal. In other words, uncorrelated signal is first generated from mono speech signal passing though the decorrelator, and it is added to ...

Epithelial cells frequently display--in addition to the common apical-basolateral polarity--a polarization within the plane of the epithelium. This is commonly referred to as planar cell polarity (PCP) or tissue polarity. Examples of vertebrate PCP include epithelial patterning in the skin and inner ear, and also the morphogenetic movements of mesenchymal cells during convergent extension at ga...

Optical computing has been suggested as a means of achieving a high degree of parallelism for both scientific and symbolic applications. While a number of implementations of logic operations have been forwarded, all have some characteristic that prevents their direct extension to functions of a large number of input bits. We analyze several of these implementations and demonstrate that all thes...

the purpose of this paper is to design entrepreneurship model of agricultural extension in the context of agricultural sustainable development. in fact the purpose of this paper is to identify the prerequisite (the influential factors of entrepreneurship), process (development of entrepreneurial program in organization); context (extension perspective in the context of agricultural sustainable ...

This paper is well targeted in researching several researches of various tool wear monitoring methods in domestic and foreign. Five important tool wear methods are deeply investigated and described in detail. Through comparing the advantages and disadvantages of each monitoring method according to practical application, and draw a conclusion that the based on multi-sensors method is considered ...
