As new products are generally difficult to be accepted by consumers, and the cost of initial market introduction is high, enterprises often choose to do market extension of an existing brand. Simultaneously, a successful brand extension can enhance the reputation of the original brand, and expand the brand value. But how can enterprise take a good brand extension? Through establishment of a dyn...

This paper gives the concepts of extension error set and fuzzy extension error set, discusses diverse extension error set and fuzzy extension error set based on extension set and error set, and puts forward the relevant propositions and operations. Finally, it provides proofs of the soundness and completeness for the propositions and operations.

The interaction of automatic semigroups and Bruck–Reilly extensions is studied. It is proved that every automatic Bruck–Reilly extension has an automatic base semigroup. This result is then applied to answer negatively the question of Andrade et al. on whether automatic structures for Bruck–Reilly extensions of groups are characterized by the fellow traveller property. An example is exhibited t...

The Internet gives individuals more choice in political news and information sources and more tools to filter out disagreeable information. Citing the preference described by selective exposure theory — people prefer information that supports their beliefs and avoid counter-attitudinal information — observers warn that people may use these tools to access only agreeable information and thus liv...

In this paper, we propose a non-realtime speech bandwidth extension method using HMM-based speech recognition and HMM-based speech synthesis. In the proposed method, first, the phoneme-state sequence is estimated from the bandlimited speech signals using the speech recognition technique. Next, for estimating spectrum envelopes of lost high-frequency components, an HMM-based speech synthesis tec...

In this paper we continue the investigation started in [AMStu], dealing with bialgebras A with an H-bilinear coalgebra projection over an arbitrary subbialgebra H with antipode. These bialgebras can be described as deformed bosonizations R#ξH of a pre-bialgebra R by H with a cocycle ξ. Here we describe the behavior of ξ in the case when R is f.d. and thin i.e. it is connected with one dimension...

the main purpose of this study was to investigate the level of agricultural extension entrepreneurship in the process of sustainable agricultural development. the statistical population of the study was composed of agricultural extension experts (n=2882). the method of sampling was a systematic random sampling one. questionnaire was the means employed for data collection. questionnaire validati...

In this paper, a new approach that extends narrow-band excitation signals using synchronous overlap and add (SOLA) of spectra have been proposed. Although artificial bandwidth extension (ABE) of speech has been extensively studied, the role of excitation spectra has not been as widely studied as the spectral envelope extension. In this study ABE is investigated with the widely used source-filte...

the study was carried out to assess the implication of the use of selected information and communication technologies (icts) for extension service delivery in nigeria. the simple random technique was used to select fifty percent of the total extension agents which equivalent to forty-two respondents as sample size for the study. frequency counts, percentages, mean and standard deviation were us...

this study is aimed at evaluating and measuring the factors affecting the dezful wheat farmers` attitude toward the extension of wheat waste reduction. the method of research was correlative- descriptive. the population of this study is all farmers cultivated wheat in dezful from 2011 to 2012 (n=5291). the number of samples size was 360 based on krejcie and morgan table. panel of experts and al...
