Comparing particulate matter dispersion in Thailand using the Bayesian Confidence Intervals for ratio of coefficients of variation

Recently, harmful levels of air pollution have been detected in many provinces of Thailand. Particulate matter (PM) contains microscopic solids or liquid droplets that are so small that they can be inhaled and cause serious health problems. A high dispersion of PM is measured by a coefficient of variation of log-normal distribution. Since the log-normal distribution is often used to analyse environmental data such as hazardous dust particle levels and daily rainfall data. These data focus the

ESTIMATING POPULATION COEFFICIENT OF VARIATION USING A SINGLE AUXILIARY VARIABLE IN SIMPLE RANDOM SAMPLING

This paper proposes an improved estimation method for the population coefficient of variation, which uses information on a single auxiliary variable. The authors derived the expressions for the mean squared error of the proposed estimators up to the first order of approximation. It was demonstrated that the estimators proposed by the authors are more efficient than the existing ones. The results of the study were validated by both empirical and simulation studies.

On the basis of coefficients of variations VRe, partial factors of the yield strength γm were estimated. Because of the shape and thickness of the corrugated web in SIN girders, numerous phenomena occur that are related to web shear resistance. They are reported in studies [1, 2, 5, 6, 7

Power Size Biased Two-Parameter Akash Distribution

In this paper, the two-parameter Akash distribution is generalized to size-biased twoparameter Akash distribution (SBTPAD). A further modification to SBTPAD is introduced, creating the power size-biased two-parameter Akash distribution (PSBTPAD). Several statistical properties of PSBTPAD distribution are proved. These properties include the following: moments, coefficient of variation, coefficient of skewness, coefficient of kurtosis, the maximum likelihood estimation of the distribution

In addition, mycelial and secreted protein profiling by 2D-PAGE showed at least three and five different protein spots in the range of 25 kD to 100 kD, respectively, in PfCM4. It seems that the variation in genetic similarity and different expression of both mycelial and secreted proteins in PfCM4 in comparison to the wild type could likely be correlated with its increased cellulolytic activity effected by the irradiation.

USING SYMBOLIC DATA IN GRAVITY MODEL OF POPULATION MIGRATION TO REDUCE MODIFIABLE AREAL UNIT PROBLEM (MAUP)

Spatial analyses suffer from modifiable areal unit problem (MAUP). This occurs while operating on aggregated data determined for high-level territorial units, e.g. official statistics for countries. Generalization process deprives the data of variation. Carrying out research excluding territorial distribution of a phenomenon affects the analysis results and reduces their reliability.

The practitioner should carefully evaluate the lateral cephalogram of CLP patients for CVA, which otherwise may remain undetected and lead to neurological symptoms later in life.

Biocontrol of Gray Mold Decay in Pear by Bacillus amyloliquefaciens Strain BA3 and its Effect on Postharvest Quality Parameters

other treatments, the inhibition effect on gray mold of washed cell suspension of B. amyloliquefaciens was the best. Consequently it was utilized in subsequent experiments. Spore germination and germ tube length of Botrytis cinerea was 18.72% and 12.85 μm treated with BA3, while the control group was 62.88% and 30.44 μm. We confirmed that increase of the concentration of B. amyloliquefaciens, improved the efficacy of BA3 in controlling gray mold decay of pears. Colonization variation of BA3 in

Variations in cognitive functioning in genetic generalized epilepsy: four case studies

typically began reflexive seizure episodes with facial myoclonia which evolved into tonic-clonic convulsions or generalized myoclonic seizures. These patients had widespread attention and working memory deficits, some severe, together with lowered intelligence scores. In contrast, two other cases (with no history of myoclonus) had generalized reflexive seizures originating in the occipital lobes, very mild localized visual dysfunction and high intelligence. Conclusions. The systematic variation in

salt are tedious. The system advancement cost of these methodologies is high. The dielectric properties of the water change, when the salt and sugar are dissolved in the water (Cheng et al., 2014b). The variation in the dielectric properties of solution with different concentrations of salt and sugar causes the changes in the properties of radio frequency (RF) signals. Antennas are commonly used in wireless communications for transmitting and receiving electromagnetic (EM) signals. Antennas and

Case report: immune anti-D stimulated by transfusion of fresh frozen plasma

FFP has occasionally been reported to generate an immune response to RBC antigens (e.g.,anti-D and anti-Fya). The Council of Europe requires that each unit of FFP have less than 6 ×109/L RBCs. However, there is considerable variation internationally in the method of production and the level and assessment of RBC contamination of FFP . This study reports the case of a 63-year-old group B, D– man who received multiple transfusions of D– blood products over a 4-month period

Speed Compliance in Freeway Variable Speed Limit System – Case Study of the Prague City Ring

Many previous studies have confirmed the strong relationship between speed compliance and the frequency and severity of traffic accidents. Variable speed limit (VSL) system as a measure to improve traffic safety enables the freeway system to change its posted speed limit based on various traffic and environmental conditions. Such system helps drivers to recognize the upcoming events, to adjust their driving style and in such way to address speed variation of the traffic flow. This is called

A study of personnel preparation of teachers of learners with vision impairment and O&M services

A review of the 50 US state education websites revealed wide variation among state O&M credentials. Less than half of the states designated a qualified provider as a credentialed O&M specialist and many identified a role for the Teachers of Learners with Vision Impairment (TVI) in providing Individualised Education Program (IEP)-driven O&M-related services. A survey of US Personnel Preparation programs preparing TVIs asked respondents to select the O&M curricular items they
