A system called CWEED, which measures energy in Ontario and it can "provides solar global measurements as the total of direct and diffuse radiant energy received by a pyranometer." (Hoicka, Rowlands,2011). Therefore, an efficient system can determine whether citizens have easy access to reliable energy or not. However, in some developing countries…

Questionnaire-related Measurement Error Questionnaire- related measurement error could have occurred in a couple questions within our survey because of the way that the questions were worded and the possible answers that were listed. One of the questions where this occurred was in question 8 that asks, “Should the U.S. immigration laws be made stricter, looser, stay about the same, or are you uncertain?” This represents a questionnaire- related measurement error because this question does not…

Aim The aim of this practical is to measure the effect of volume, density and temperature. It is also help to be familiar with variety of common laboratory technique. Materials Weighting scale Container with lids 20 and 10 ml Volumetric pipette Beaker Thermometer Test Tubes Volumetric flask Natural Rubber Pipette Filler Micropipette tips Tips boxes Method There are two pipette, choose one which you using in whole practical. Label and weight accurately, to 4 decimal places. Collect…

and blew through the end that was capped by the finger. The free floating bubbles were allowed to descend to the ground where their diameter was measured by a ruler. We found the averages by adding both the measurements of each solution in each test and dividing them by the number of measurements, two. For example: 1.25+1.30+1.20=3.75/3=1.25 average. There were multiple steps taken to prepare our data taken for analysis. Throughout our study, we took observations on the solutions and their…

ASTM STANDARDS Short introduction – ASTM standards are consensus standards for systems, services, materials and products. ‘ASTM International’ is one of the largest voluntary standard developing organization in the world. It is a non-profit organization that provides a forum for the development and publication of international voluntary standards. There are approximately 12,575 ASTM standards that operate globally. TESTING ASTM STANDARDS- Scope- There test methods help in the determining of…

Prior to field measurements (during the identification field experience), practice cover estimates were recorded randomly on the site to ensure consistency. Percentage of canopy density was measured using a convex spherical forest densiometer, instrument design to estimate…

During the course of this practical, the different factors of a pendulum will be investigated. A pendulum is a mass held from a fixed point so it is able to swing freely, the mass swings back and forth in an arc. The formula for finding the period of a certain pendulum lies in the change of the length of string suspending the mass, and the force due to gravity where the pendulum is being used. This relationship is shown in the equationT=2π√( L/g) (Sean, 2010), as the length of the string…

Office Spaces is updating their office chairs and have decided to alter the material and cross section of the arm supports. They have requested our assistance in evaluating several materials through experiments and simulations. The purpose of this experiment is to test these various materials and to recommend a material choice and cross section geometry that will minimize deflection of the arm supports. The following sections of this memorandum will detail several facets of the experiment.…

(“Wikipedia”). Typically, if one were to place a weight towards the free end of a cantilever, some bending, or flexion, would be expected. Flexion, in this case, is the action of bending or the condition of being bent (“Merriam-Webster”). Given that angle measurements are involved, a protractor is typically used to measure flexion at the bending point of the cantilever. As stated before, the fact that flexion will occur as the cantilever length changes is already known. I want to see how much…

Eljelly, (2004) explained that proficient liquidity administration includes arranging and controlling current resources and current liabilities in such a way, to the point that kills the danger of failure to meet due transient commitments and evades unnecessary interest in these benefits. The relationship in the middle of benefit and liquidity was analyzed, as measured by current proportion and money hole (money transformation cycle) on an example of business entities in Saudi Arabia utilizing…
