  • The wide geographical distribution of the rice plant ( Oryza sativa L.) and its long history of cultivation in Asian countries have led to the development of a great diversity of varietal types. Similarly, workers in various rice-growing countries use different terms to designate identical morphological and physiological characters, agronomic traits, gene symbols, and cultural practices. Whereas varietal diversity in germ plasm is desired in rice breeding, variations in nomenclature hinder scientific communication among the workers.

  • Most previous studies of morphological disambiguation and dependency parsing have been pursued independently. Morphological taggers operate on n-grams and do not take into account syntactic relations; parsers use the “pipeline” approach, assuming that morphological information has been separately obtained. However, in morphologically-rich languages, there is often considerable interaction between morphology and syntax, such that neither can be disambiguated without the other.

  • Calcium carbonate scale inhibition in squeeze treatment by the phosphonate–type scale inhibitors, such as diethylenetriamine penta (methylene phosphonic acid) (DETPMP), ethylene diamine tetra(methyelne phosphonic acid) (EDTMP) or by the mixing of DETPMP, EDTMP and chelants (citric acid (CA), maleic acid (MA), ethylendiamintetraacetic acid (EDTA) has been studied in previous works [5,6].

  • Cancellation Policy If your cancellation is received in writing via mail, fax or email prior to the start of the program, you will receive a refund of the program fee less a $100 cancellation fee. The $150 application fee is nonrefundable. Given the special nature of FSBE, requests for refunds after the start of each semester will not be granted. If UC Berkeley Extension expects to cancel a program, you will be notif ied at least 15 days before the scheduled start date and offered alternative study arrangements if available; otherwise, you will be given a full refund.

  • This paper describes our work on building Part-of-Speech (POS) tagger for Bengali. We have use Hidden Markov Model (HMM) and Maximum Entropy (ME) based stochastic taggers. Bengali is a morphologically rich language and our taggers make use of morphological and contextual information of the words. Since only a small labeled training set is available (45,000 words), simple stochastic approach does not yield very good results. In this work, we have studied the effect of using a morphological analyzer to improve the performance of the tagger. ...

  • For centuries, the deep connection between languages has brought about major discoveries about human communication. In this paper we investigate how this powerful source of information can be exploited for unsupervised language learning. In particular, we study the task of morphological segmentation of multiple languages. We present a nonparametric Bayesian model that jointly induces morpheme segmentations of each language under consideration and at the same time identifies cross-lingual morpheme patterns, or abstract morphemes. ...

  • This paper presents a feasibility study for implementing lexical morphology principles in a machine translation system in order to solve unknown words. Multilingual symbolic treatment of word-formation is seducing but requires an in-depth analysis of every step that has to be performed. The construction of a prototype is firstly presented, highlighting the methodological issues of such approach. Secondly, an evaluation is performed on a large set of data, showing the benefits and the limits of such approach. ...

  • Morphological response to port construction on sendai coast. The difference in topographic evolution observed in both cases caused by the layout of coastal structures interacted with wave action which should have more clear understanding before the construction of any sea defences. This study also attempted to analyse the shoreline behaviour around Nanakita River mouth by utilising the aerial photograph. The GIS tool also is used in processing aerial photograph which have taken regularly in that area.

  • There are many methods for treating infertility patients. IVF plays an important role in the field of assisted reproduction and their demands are increasingly widespread in the world. However, the success rate in assisted reproduction only reached 30 - 40%. Currently, most are choosing embryos based on morphological criteria of the embryo. However, the morphological assessments do not fully reflect the true quality of the embryos, if only based on morphological parameters, the results of in vitro fertilization treatment is limited.

  • This study was based on applying fractal geometry, GIS on large-scale maps for identifying residential density based on urban morphology. The land-use map and the building footprints map of 2010 were integrated in fractal geometry to analyze the distribution of urban areas by the large scale of GIS data.

  • Electrospraying is an effective method to produce polycaprolactone microparticles for drug or protein carrier application. In this study, some factors which influenced the morphology of polycaprolactone (PCL) particles were investigated by Scanning Electron Microscopy (SEM), such as polymer concentration, solvent and distance from tip to the collector.

  • The experimental results showed that there was a significant influence of base agent nature on the morphology, structure, surface area of TiO2 product. Using NH3 agent could obtain uniform TiO2 particles with about 15 nm in size and surface area of 98.93 m2 .g-1 , while using NaOH or KOH led to TiO2 with varying particle sizes (in the range of 15-500 nm), and decreasing surface area (less than 20 m2 .g-1 ).

  • The purpose of this study is a taxonomic review of the family Labridae distributed in Vietnam. Currently, 11 species belong to Cheilinus, Halichoeres, Iniistius, Scarus, and Oxycheilinus are described based on morphological characters. Combined with Genbank sequences, a phylogenetic tree was constructed based on 16S gene of mitochondrial DNA. A comprehensive survey and checklist update of Labridae in Vietnam is necessary.

  • In this research, we mainly present the effect of modified waste-gypsum (MWG) contents on the rheological, physico-mechanical and thermal properties of the PVC/MWG polymeric composite materials. Four kinds of rigid PVC/MWG composite with different MWG contents were prepared by melt blending method. The morphological development of the PVC/MWG polymeric composite samples is also discussed in this paper.
