Motivated by an application in image processing, we introduce the grid-leveling problem. It turns out to be the dual of a minimum cost flow problem for an apex graph with a grid graph as its basis. We present an O(n) algorithm for this problem. The optimum solution recovers missing DC coefficients from image and video coding by Discrete Cosine Transform used in popular standards like JPEG and M...

elegiac poetry written about the ahlolbeit (the holy prophet’s household) in khuzestani arabic is a rich folklore source. this poetic genre is beautiful and appealing and almost comprehensible for its audience. however, it is mysteriously difficult for all to read. this often leads to misunderstandings. the incomprehensibility of khuzestani arabic may be due to different reasons. for example,...

Determining the language proficiency level required to understand a given text is a key requirement in vetting documents for use in second language learning. In this work, we describe our approach for developing an automatic text analytic to estimate the text difficulty level using the Interagency Language Roundtable (ILR) proficiency scale. The approach we take is to use machine translation to...

the different constructions of [ah] which is an infinitive are prevalent in the dialect of the historical village of xanik and its neighboring villages. singular second person paradigm in present tense of [ah] infinitive in the dialect is a survivor of sanskrit and old persian languages. some constructions of this infinitive are widely used, because they are attributive verbs meaning is being a...

as pioneer trends in iranian computational dialectology, the leveneshtain algorithm applied to mazandarani dialect data - extracted from lai – revealed regional dialect in the northern range of the alborz mountains. current synchronic fieldwork aimed to determine vowels responsible for regional variation, and likewise reliability and validity of the research findings, through vowel frequency me...

The purpose of this research paper is to study the tool wear and surface roughness of AISI 8620 material using coated ceramic tool by turning process. Ceramic cutting tools have outstanding material hardness, resistance to high temperatures, wear resistance, chemical stability and hot hardness. Ceramic tool with Al2O3 + TiC (golden) coating was used to investigate the surface roughness and tool...

In this work, we focus on the problems of the automatic treatment of oral spoken in the Tunisian media. This oral is marked by the use of code-switching between the Modern Standard Arabic (MSA) and the Tunisian dialect (TD). Our goal is to build useful resources to learn language models that can be used in automatic speech recognition applications. As it is a variant of MSA, we describe in this...

This paper examines tone features on the basis of an acoustic phonetic analysis of F0 and duration data from 10 speakers in Qimen Hui Chinese Dialect. The results show that there are 3 level tones, 2 rising tones, and 1 falling tone in Qimen. The fact that speakers use different F0 contours in the realization of different types of level tones sheds light on the understanding of underlying mecha...

An experiment was conducted to examine whether word initial pitch accent information could be exploited to reduce possible word candidates by speakers of an accentless dialect in Japan. 40 native high school students from Fukushima were presented with Tokyo Japanese materials used in an earlier study, employing a gating task. Results show that the subjects performed significantly above chance, ...
