I have been associated with uncertainty calculations for quite sometime. Asia
Metrology Program (APMP) took interest in unification of expressing the measurement
results along with uncertainty. In those days the uncertainty components
were divided according to source of errors. The errors were named as random
and systematic errors. Hence components of uncertainty were named random
uncertainty and systematic uncertainty. Around 1980, BIPM took initiative by
circulating questioners to the countries who were members of Metre Convention.

After we have set out the objectives for an investment, considered the challenges to reaching them, developed a strategy with the optimal chance of meeting our goals, allocated assets to asset classes and managers, and purchased the securities to build our portfolios, the next step is to check the results. Investment performance measurement is the quantification of the results achieved by an investment program. This book describes and demonstrates the techniques we use to measure investment performance....
Many important decisions are based on the results of chemical quantitative analysis; the results are used, for
example, to estimate yields, to check materials against specifications or statutory limits, or to estimate
monetary value. Whenever decisions are based on analytical results, it is important to have some indication
of the quality of the results, that is, the extent to which they can be relied on for the purpose in hand.

Perhaps quantum mechanics is viewed as the most remarkable development in 20th century physics. Each successful theory is exclusively concerned about "results of measurement". Quantum mechanics point of view is completely different from classical physics in measurement, because in microscopic world of quantum mechanics, a direct measurement as classical form is impossible. Therefore, over the years of developments of quantum mechanics, always challenging part of quantum mechanics lies in measurements.
We classify measures on the locally homogeneous space Γ\ SL(2, R) × L which are invariant and have positive entropy under the diagonal subgroup of SL(2, R) and recurrent under L. This classiﬁcation can be used to show arithmetic quantum unique ergodicity for compact arithmetic surfaces, and a similar but slightly weaker result for the ﬁnite volume case. Other applications are also presented. In the appendix, joint with D. Rudolph, we present a maximal ergodic theorem, related to a theorem of Hurewicz, which is used in theproof of the main result. ...
State-of-the-art statistical machine translation (MT) systems have made signiﬁcant progress towards producing user-acceptable translation output. However, there is still no efﬁcient way for MT systems to inform users which words are likely translated correctly and how conﬁdent it is about the whole sentence. We propose a novel framework to predict wordlevel and sentence-level MT errors with a large number of novel features. Experimental results show that the MT error prediction accuracy is increased from 69.1 to 72.2 in F-score. ...
Large expenses associated with rice production and dependence on energy related inputs like fuel and fertilizer in particular compel rice producers to use management practices that are input efficient and result in least cost. This study uses data envelopment analysis (DEA) to calculate technical efficiency (TE), allocative efficiency (AE), and economic efficiency (EE) for rice production in Arkansas at the field level using data from 137 fields enrolled in the University of Arkansas, Rice Research Verification Program (RRVP) from 2005 to 2011.
As a consequence of the increasing importance of tritium resulting
from nuclear fission and neutron activation, from its use in accelerators,
from its use in research and industry, and from its use in the
investigation of the environment and its distribution in the environment,
the NCRP designated a scientific committee to prepare a report
on the currently acceptable methods of measuring tritium. This
report is particularly aimed in assisting an individual to select a
procedure suitable to the problem at hand....
Every week’s news brings fresh reminders of the complex array of challenges facing
contemporary organizations in every sector. While the realities of organizational
life may have actually changed very little over the years, the public perception is
otherwise as we are bombarded with reports of inefficiencies, ethical violations,
greed, cost overruns, corruption, unwieldy bureaucratic procedures, waste, an
absence of planning, and leadership ineptness.
We present a human-robot dialogue system that enables a robot to work together with a human user to build wooden construction toys. We then describe a study in which na¨ve subjects interacted with this ı system under a range of conditions and then completed a user-satisfaction questionnaire. The results of this study provide a wide range of subjective and objective measures of the quality of the interactions.
This paper presents methods for a qualitative, unbiased comparison of lexical association measures and the results we have obtained for adjective-noun pairs and preposition-noun-verb triples extracted from German corpora. In our approach, we compare the entire list of candidates, sorted according to the particular measures, to a reference set of manually identiﬁed “true positives”. We also show how estimates for the very large number of hapaxlegomena and double occurrences can be inferred from random samples.
This paper presents the calculations using LITPACK models, aiming to select the restoration solution for Cua Tung beach, severely eroded in recent years. The results are just the preliminary, but they are useful to direct the optimal measures to bring the beach back to its original state serving the social and economic development in Quang Tri province. Keywords: MIKE, LITPACK, erosion, cross-sections, sediment, coastline.
1. Introduction∗ Cua Tung beach of Quang Tri province was one of the most beautiful ones, attracting many...
nnovation is widely acknowledged as being key to economic growth and progress, particularly as innovation by business enterprises is vital in ensuring their future success and competitiveness in an increasingly competitive global market. With this in mind, the Centre for Science, Technology and Innovation Indicators (CeSTII) was commissioned by the Department of Science and Technology (DST) to undertake a national innovation survey based on international best practice.
At the request of the U.S. Department of Education, the National
Research Council’ s (NRC) Board on Testing and Assessment (BOTA) con-
vened a workshop on reporting test results for individuals who receive ac-
commodations during large-scale assessments. The workshop brought to-
gether representatives from state assessment offices, individuals familiar with
testing students with disabilities and English-language learners, and mea-
surement experts to discuss the policy, measurement, and score use consid-
erations associated with testing students with special needs.
In this paper we present research in which we apply (i) the kind of intrinsic evaluation metrics that are characteristic of current comparative HLT evaluation, and (ii) extrinsic, human task-performance evaluations more in keeping with NLG traditions, to 15 systems implementing a language generation task. We analyse the evaluation results and ﬁnd that there are no signiﬁcant correlations between intrinsic and extrinsic evaluation measures for this task.
