A Bayesian model for the determination of optimal sampling intervals

Creator:: Paradis, Garry Lynn
Abstract:: There are a nearly unlimited number of situations in which the status of time-varying processes must be updated. The monitoring of these processes usually occurs at periodic intervals. Whether the monitoring is performed by man or machine, a decision must be made regarding the frequency of these activities, that is,...

Automatic sampling for seed analysis

Creator:: Knudson, Larry Andrew
Abstract:: Experiments were designed to reveal the accuracy and precision of four types of automatic sampler prototypes after initial testing indicated that the single tube vibrator sampler was not drawing a complete cross section of the seed flow in a vertical column. These experiments compared the automatic samplers with the trier...

A mixed variables-attributes double sampling plan

Creator:: Harmer, Dale Leroy
Abstract:: This thesis presents a table of dependent, mixed variables and attributes double sampling plans, where the standard deviation of the quality characteristic is assumed to be known, and the acceptance number is zero for the attributes portion of the plans. The table gives sampling plans for ten ranges of lot...

Determination of optimum raw product sampling procedures with special reference to green beans for processing

Creator:: Ellis, Bruce Byron
Abstract:: Most raw product received at processing plants in Oregon is sampled to determine quality characteristics as a basis of grower payment. Raw product sampling procedures must provide the processor with a means of sampling which will be sufficiently precise to satisfy himself as well, as his growers, and thus avoid...

A computerized approach to finding the minimum sample size for single sample attribute sampling plans

Creator:: Sylvester, Lancelot G.
Abstract:: Much has been written concerning the determination of a single sampling plan given two points on the operating characteristic (OC) curve. A computer program is presented which will provide minimum sample size for single sample attribute sampling plans. The program provides sampling plans based on the binomial distribution. It incorporates...

Evaluation of the limit number effects for reduced inspection in ANSI/ASQC Z1.4 using a Markov model

Creator:: Grinde, Roger B.
Abstract:: ANSI/ASQC Z1.4 is a widely used attributes acceptance sampling system. A necessary aspect of a scheme, from both a theoretical and psychological viewpoint, is the switching between normal, tightened, and reduced inspection as a function of quality history. In the latest revision of the standard the switching rules were altered...

An evaluation of the punch card method of estimating salmon-steelhead sport catch

Creator:: Hicks, Ronald Herbert
Abstract:: A primary objective of the management practices of the Oregon State Game Commission is to maximize and sustain the annual harvest of salmon and steelhead by sportsmen fishing in Oregon. Assessment of these practices is dependent upon an accurate determination of total annual sports harvest throughout the state. Present total...

Comparison between lichen, conifer needles, resin-based passive air sampling devices (PASDs), and snow to monitor semi-volatile organic compounds (SOCs) in the atmosphere

Creator:: Schrlau, Jill E.
Abstract:: The purpose of this research was to compare four different media that were used to monitor SOC atmospheric concentrations in remote ecosystems. The accumulation of semi-volatile organic compounds, including pesticides, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), was investigated in lichen, 2-year old conifer needles, resin-based passive air sampling...

Behavior of estimates of the mean life of a radioactive source

Creator:: Butler, Stephen Walter
Abstract:: This thesis presents the results of sampling experiments investigating the properties of estimates of the mean life of a radioactive source in the presence of a constant unknown background. An iterative estimation procedure is used where the estimates are maximum liklihood estimates with asymptotic variances. The estimation procedure was programmed...

Behavioral thresholds in mixtures of sand and clay

Creator:: Simpson, Daniel Corder
Abstract:: Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced (and in some cases, governed) by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...

Moisture Monitoring of Cross Laminated Timber Building Components

Creator:: Schmidt, Evan L.
Abstract:: Cross laminated timber (CLT) is a relatively new engineered wood product that has elevated the prospects of utilizing wood as the primary structural material for mid and high rise buildings. The hygrothermal performance of CLT, however, is still not well understood at the material, assembly and building scales. A major...

A sensitivity evaluation of EPA's CAL3QHC dispersion model for carbon monoxide analysis at urban intersections

Creator:: Lindemann, Julie B.
Abstract:: In February 1994, EPA proposed to "refine" its carbon monoxide (CO) hot spot model, CAL3QHC, to increase its accuracy and reliability. Currently, this proposal includes using hourly meteorological data recorded at airports near the modeling sites instead of the worst case conditions now recommended as a modeling default. The analysis...

Development and application of an analytical technique for the determination of methylmercury compounds in environmental samples based on isolation by distillation, followed by purge-and-trap sample concentration and GC/MS separation and detection, after aqueous phase ethylation with sodium tetraethylborate

Creator:: Rice, William R.
Abstract:: An analytical technique has been developed for the determination of methylmercury compounds in environmental samples. The technique is based on a two-stage procedure. In the first stage, methylmercury compounds are isolated from the sample matrix as methylmercury chloride (MeRgCl) by distillation. The distillation procedure is based on a series of...
