Tuyển tập báo cáo các nghiên cứu khoa học quốc tế ngành hóa học dành cho các bạn yêu hóa học tham khảo đề tài: Source Depth Estimation Using a Horizontal Array by Matched-Mode Processing in the Frequency-Wavenumber Domain
This book is intended to provide an introduction to the technical concepts of wastewater treatment. It assumes that the reader has at least a first-year undergraduate level of scientific understanding but not necessarily any previous knowledge of wastewater treatment. A reading list is provided at the end of the book for more in-depth information on the topics that are introduced here.
The authors are based in the United Kingdom and therefore the scientific units and terminology that are used in this book are those which are common in that country....
Computer vision is one of the most studied subjects of recent times with paramount
focus on stereo vision. Lot of activities in the context of stereo vision are getting
reported spanning over vast research spectrum including novel mathematical ideas,
new theoretical aspects, state of the art techniques and diverse range of applications.
Note that when node 7 produces a tuple that joins with
the static table, three transmissions result; this is the same
as if the original data was sent up the routing tree in the
naïve or single-node case. In the worst case, there would
have been two extra tuples: if node 5 produced a tuple
which joined with a tuple on node 7 a total of 4 transmis-
sions would have been performed. In general, no more
than 2 + depth transmissions will be required, as any pair
of nodes in the same group differ by no more...
Forests play a major role in global carbon
(C) cycle, and the carbon density (CD) could reflect
its ecological function of C sequestration. Study on
the CD of different forest types on a community scale
is crucial to characterize in depth the capacity of
forest C sequestration.
For small join tables, REED always chooses to push
them into the network if their selectivity is smaller than
one. For intermediate tables, the REED query optimizer
makes a decision as to whether to push the join into the
network based on the estimated selectivity of the predicate
(which may be learned from past performance or gathered
statistics, or estimated using basic query optimization tech-
niques ) and the average depth of sensor nodes in the
In recent years, under impacts of human activities and climate change, flood has been increased in both the frequency and magnitude, causing lots of damages to people. This study presents a method to evaluate the direct spatial damages of flooding based on inundation depth and land use data. Damage functions for different types of land use arc selected and applied. Matlab strings and GIS are combined to calculate damage in monitery term. The method is applied for estimating loss caused by thc flood event November 1999 for Huong rivce basin.
· Physical vs. monetary accounts. Physical accounts only include information about
natural characteristics of the environment and its use; the size of forests or mineral
reserves, the quality of water or air, the depth of topsoil, etc.. In contrast, monetary
accounts place an economic value on those characteristics or their use, so as to
understand the role they play in the economy. Given the difficulty of estimating the
monetary value of certain aspects of the environment, some individuals (and countries)
advocate development of only physical accounts.
· Integrated accounts vs.
