The continuous survey hull (CSH) and Continuous survey machinery (CSM) are survey methods for the mooring, anchoring and the propulsion system. The special survey cycle (SS) is an alternative for the CSH [clarification needed] and Engine survey (ES) for the CSM. The annual survey (AS) is an inspection of the safety equipment.
The Safety Equipment Institute (SEI) is a private, non-profit organization established to administer non-governmental, third-party certification programs to test and certify a broad range of safety and protective products. [1] As of April 2016, it became an affiliate of ASTM International, a global standards development organization. [2]
Sample preparation equipment refers to equipment used for the preparation of physical specimens for subsequent microscopy or related disciplines - including failure analysis and quality control. The equipment includes the following types of machinery: Precision cross-sectioning saws; Precision lapping & polishing machines; Selected Area ...
In analytical chemistry, sample preparation (working-up) refers to the ways in which a sample is treated prior to its analyses. Preparation is a very important step in most analytical techniques, because the techniques are often not responsive to the analyte in its in-situ form, or the results are distorted by interfering species .
A soil sample recovered from a test boring using a split spoon sampler. Borings come in two main varieties: large diameter and small diameter. Large-diameter borings are rarely used because of safety concerns and expense but are sometimes used to allow a geologist or an engineer to visually and manually examine the soil and rock stratigraphy in-situ.
The nearly perfect squareness and north–south orientation of the Great Pyramid of Giza, built c. 2700 BC, affirm the Egyptians' command of surveying. [2]A recent reassessment of Stonehenge (c.2500 BC) suggests that the monument was set out by prehistoric surveyors using peg and rope geometry.
Survey methodology is "the study of survey methods". [1] As a field of applied statistics concentrating on human-research surveys, survey methodology studies the sampling of individual units from a population and associated techniques of survey data collection, such as questionnaire construction and methods for improving the number and accuracy of responses to surveys.
