We verify an old conjecture of G. P´lya and G. Szeg˝ saying that the o o regular n-gon minimizes the logarithmic capacity among all n-gons with a ﬁxed area. 1. Introduction The logarithmic capacity cap E of a compact set E in R2 , which we identify with the complex plane C, is deﬁned by (1.1) − log cap E = lim (g(z, ∞) − log |z|),
where g(z, ∞) denotes the Green function of a connected component Ω(E) ∞ of C \ E having singularity at z = ∞; see [4, Ch. 7], [7, §11.1]. By an n-gon with...
Recently, tourism activities in Quang Binh Province have been growing rapidly, especially since the Phong Nha - Ke Bang National Park was certified as the World Natural Heritage in 2004. Among the tourist sites of Quang Binh, Phong Nha and Dong Hoi tourism centers are the two places which attract the largest numbers of visitors. The rapid but unplanned tourism activities have been creating various social and environmental concerns.
Let ϕ : C → C be a bilipschitz map. We prove that if E ⊂ C is compact, and γ(E), α(E) stand for its analytic and continuous analytic capacity respectively, then C −1 γ(E) ≤ γ(ϕ(E)) ≤ Cγ(E) and C −1 α(E) ≤ α(ϕ(E)) ≤ Cα(E), where C depends only on the bilipschitz constant of ϕ. Further, we show that if µ is a Radon measure on C and the Cauchy transform is bounded on L2 (µ), then the Cauchy transform is also bounded on L2 (ϕ µ), where ϕ µ is the image measure of µ by...
The project uses a dual approach which focuses on both the physical / scientific dimension of aquaculture and the educational / training dimension of aquaculture extension program development. This dual approach enables the improvement of aquaculture practises resulting from Dimension 1 to be consolidated and disseminated more broadly through provincial aquaculture communities per medium of the activities of Dimension 2. The project supports capacity building in both aquaculture management and aquaculture extension (community education)....
The University of Queensland, together with its Vietnamese partner institutions, propose a CARD project to enhance the teaching and research capacity of staff in the three institutions. This will be achieved through a project targeting agroforestry systems for livestock feeding in the northern provinces of Vietnam. The project will focus on the use of adapted multipurpose trees in small holder farming and livestock feeding systems.
There are five Quaternary sedimentary sequences in the Red River Delta, Vietnam. The forming of each sequence is related to transgression and regression phases. The sequences, which was formed in transgression period, composed mainly of fine grained size leading to the water bearing capacity is very low and plays a role as aquicludes. Besides, in these fine grain size layers, the contents of arsenic and iron are high, especially in dark clay, silty clay rich in organic material ...
Vietnam has more 3000km of coastline and the features of the coastal zone in various areas (Northeast area, Red River Delta, Central Region and Mekong River Delta) are also different. Therefore, it is necessary to study specific characteristics of each area and find out the suitable boundaries for the coastal zone.
Galloylated and nongalloylated catechin conjugates with cysteine deriva-tives have been synthesized and evaluated for their capacity to scavenge
free radicals and to influence crucial functions (cell cycle, apoptosis) in
HT29 colon carcinoma cells. We show that the nonphenolic part of the
molecule modified the capacity of catechins to donate hydrogen atoms and
to transfer electrons to free radicals.
This project will enhance the capacity in Vietnam to 'train the trainers', extension workers and staff responsible for the maintenance of quality of commodities during storage and marketing.
PHTI will provide flexible integrated courses on various aspects of post-harvest commodity quality management, with particular attention to containment and loss reduction. The training group will also be able to develop new training modules applicable to contaminant reduction in fruit and vegetables as strategies for monitoring and management of contaminants in vegetables are further developed....
The overall objective of the project is to increase food security and income of rural Vietnamese in coastal communities by improving the profitability, and environmental sustainability, of intensive aquaculture in Vietnam. This addresses identified priorities of the CARD Program to build capacity in areas of fisheries and aquaculture and livestock feed improvement. This will be delivered by building the teaching and research base for aquaculture nutrition at the University of Fisheries (UoF) at Nha Trang.
The objective of this program is to improve Vietnam’s capacity for teaching and conducting research in modern horticultural crop production with a particular focus on vegetables. This should enhance the ability of Vietnam to promote rural development in these industries and improve the efficiency of and quality of vegetable production. The project aims to achieve this by:
The ability to achieve an economically efficient livestock production system and to improve the quality of agricultural research and advice in Vietnam is dependent on the capacity of feed laboratories to provide reliable nutritional and analytical data. Vietnam’s laboratories currently lack the resources and skills to meet both industry needs and the higher accreditation standards for Quality Assurance (QA) set as a Government objective. The proposed activity will assist laboratories to meets these industry needs and government goals by:...
The limited capacity of working memory is intrinsic to human sentence processing, and therefore must be addressed by any theory of human sentence processing. This paper gives a theory of garden-path effects and processing overload that is based on simple assumptions about human short term memory capacity. hypothesis, is easily compatible with the above view of processing load calculation: given a choice between two different representations for the same input string, simply choose the representation that is associated with the lower processing load. ...
We propose a novel algorithm for extracting dependencies from the derivations of a large fragment of CCG. Unlike earlier proposals, our dependency structures are always tree-shaped. We then use these dependency trees to compare the strong generative capacities of CCG and TAG and obtain surprising results: Both formalisms generate the same languages of derivation trees – but the mechanisms they use to bring the words in these trees into a linear order are incomparable.
Interpret to clarify the theoretical and practical issues, propose basic solutions to implement the fostering of scientific research capacity of students training to become lecturers in the academies and military officer colleges in the current period.
Givcn a grammar for a language, it is possible to create finite state mechanisms that approximate its recognition capacity. These simple automata consider only short context information~ drawn from local syntactic constraints which the grammar hnposes. While it is short of providing the strong generative capacity of the grammar, such an approximation is useful for removing most word tagging ambiguities, identifying many cases of iU-fonncd input, and assisting efficiently in othcr natural language processing tasks. ...
Research objectives: Can analyze the current situation and characteristics of natural rehabilitation of flora carpet on lands after shifting cultivation as a basis for building the classification of rehabilitation capacity in the study area; can assess the protection capacity of flora carpet on lands after shifting cultivation, can classify rehabilitation potential of forest on lands after shifting cultivation through forest time natural rehabilitation, and propose some silviculture solutions for forest rehabilitation on lands after shifting cultivation in the watershed protection area.
Developing a sustainable simulation system consists essentially of generating sustainable,
artiﬁcial worlds with the capacity to produce results similar to those observed in the
real world. This allows for varying parameters in a controlled, reusable experimental
environment, something that cannot be easily achieved through mathematical models.
Protected cropping provides vegetable growers with an opportunity to enhance product
quality and improve food safety. The overall objective of this project was to provide
Vietnamese scientists and extension specialists with the training and tools to implement
and foster regionally feasible improvements to current vegetable production practices and
supply chains. This was achieved through: 1) greenhouse replicated experiments and
demonstration trials in Northern, Central and Southern Vietnam; 2) four in-country
workshops and 3) two Australian study tours for research and extension personnel.
