• Hertzsprung-russell Diagram

510 Words  | 2 Pages

The Hertzsprung-Russell Diagram or, the H-R Diagram for short, is a graph which plots stars according to their temperature and absolute magnitude. This graph reveals a pattern, which in fact is quite interesting. The H-R Diagram is named for the two astronomers, Ejnar Hertzsprung and Henry Russell, who discovered this pattern of stars. These two astronomers independently discovered that comparing magnitudes and spectral class (color) of stars yielded a lot of information about them. One key purpose

• Fishbone Diagrams Cause and Effect of Wastage Events

1122 Words  | 3 Pages

Root Cause Analysis of the Causes of Wastage Fishbone Diagram (Cause-and-Effect Diagram) A fishbone diagram, also commonly known as cause and effect diagram or Ishikawa diagram, is a graphical tool to identify the potential causes of a specific event. It was invented by Kaoru Ishikawa in the 1960s for the quality management processes in the Kawasaki shipyards. The causes are grouped into major categories (usually include People, Method, Material, Machine, Measurement and Environment) to identify

• Functional Block Diagram: The Functions Of Function Blocks

805 Words  | 2 Pages

Function Block Diagram The Function Block Diagram (FBD) is a graphical language in PLC which describes the function between the input output variables. FBD is in the form of elementary blocks and number of blocks are connected together to form a logic using connection lines or links. A function block is represented in the manner shown as: The connection is oriented, i.e. the line carries data from left to the right end. The connected blocks must be of the same data type (like integer, double integer

• Top-Down Approach to Drawing Data Flow Diagrams

875 Words  | 2 Pages

The top-down approach to drawing data flow diagrams essentially involves moving “from the general to the specific” in terms of the detail level displayed (Kendall & Kendall, 2008, p. 220). Using information gathered from interviews, investigation, and personal observation, the systems analyst begins by developing a list of business activities. They then use the list to define the four elements of a data flow diagram, as follows: § External entities – send/receive data to/from the system § Data

After adjusting t... ... middle of paper ... ... lowest temperature where liquid phase is in equilibrium with solid phase. Phase diagrams are means that can be used to graphically represent the thermal behavior of mixtures by studying the compositions and temperatures at which particular phases exist, equilibrium curves, and the eutectic point. The diagram has composition on the x axis and temperature on the y-axis at a specific pressure. The equilibrium curves are the phase boundaries of the

• The Fishbone Diagram Is A Cause & Effect Diagram?

934 Words  | 2 Pages

The Fishbone Diagram (also called a Cause & Effect Diagram, or Ishikawa Diagram) is considered one of the 7 basic quality tools, and is often used as part of Lean-Kaizen workshops. A fishbone diagram that helps the assessing of the current state whilst assisting in getting to the root cause of a problem. This will help employees to identify solutions once a root cause is known. Fishbone diagram is also a good way to break a problem down in a structured way. “For every effect there is a root cause

• The Diagram Of Phase Change

994 Words  | 2 Pages

The term phase transitionxis most commonly used to describe transitions between solid, liquid and gaseous states of matter, and, in rare cases, plasma. A phase of a thermodynamic system and the states of matter have uniform physical properties. During a phase transition of a given medium certain properties of the medium change, often discontinuously, as axresult of the change of some externalxcondition, such asxtemperature, pressure, or others. For example, a liquid may become gas upon heating to

• Productivity In Construction Industry

679 Words  | 2 Pages

1.1 General Construction labour productivity has become big problem in construction industry. In many countries, labour cost comprises 30 to 50% of the overall project’s cost (Yates and Guhathakurta, 1993), and thus is regarded as a true reflection of the economic success. Because construction is labour-intensive industry, significance of this effect not only justifies the concern over its labour productivity, but it can also be argued that labour power is the only productive resource. There are

• The Fencing Problem

2933 Words  | 6 Pages

Problem There is a need to make a fence that is 1000m long. The area inside the fence has to have the maximum area. I am investigating which shape would give this. Triangles: Scalene [IMAGE] The diagram above is not to scale. Instead of having the perimeter to 1000m, only in this diagram, I have made the perimeters of the shape to 10, only to make this part of the investigation easier to understand. We know that the base of all the shapes is 2. The lengths for the equilateral triangle

• Solenoid

1226 Words  | 3 Pages

found by Hans Oersted, that when an electric current flows in a wire, the current creates a magnetic force around this wire. It is also known that a solenoid produces a considerably large amount of magnetic force when a current flows through it (diagram 1.1 ). By using a solenoid and some small, light rings of copper and aluminum, it is said that the ring when placed over the solenoid when current is flowing will 'jump' up and sometimes levitate if the force of the magnetic field equals that of the

Kahn's pursue of this vision is apparent in his design process. The earliest massing strategy was to place a linear group of vertical towers parallel to the face of the cliff (diagram 1a). In the second version, a year later, the towers were replaced by four rectilinear, two-storey blocks set perpendicular to the sea (diagram 1b). In this version, the four blocks of laboratories were made up of clear span spaces, made possible by five box girders running across each rectangle, with a 'V'-shaped folded

harmonic motion of a pendulum can be studied by attaching a ticker-tape to a pendulum bob and analyzing the dots marked on the tape. Theory ------ In this experiment, a string was used to suspend a 0.5 kg mass. [IMAGE] Refer to the diagram above, [IMAGE] Considering the tangential force on the mass, [IMAGE] [IMAGE] âˆ´The oscillation is simple harmonic. Therefore, we can find out more on simple harmonic motion by analyzing the ticker-tape we obtained after the experiment

The diagram below represents a situation in which the full employment level is illustrated. National Income \$100b This diagram presents a situation where the SRAS and the AD curve intersect on the LRAS and \$100b is the NY. The terms used in the diagram must be explained. SRAS stands for short run aggregate supply, which is the relationship between the aggregate supply

• Investigating How the Size of a Shadow Depends on the Angle at Which the Light Hits the Object

992 Words  | 2 Pages

examples: 1) The distance between the light and the object From the ray diagrams I can see that as the distance from the object to the light source is doubled, the length of the shadow decreases. A distance of 4cm produces a shadow of approximately 1.6-cm. Decreasing the distance to 2cm(half the distance), the shadow size increases by one and a half times to produce a shadow of 2.3 cm. The three ray diagrams together show the increase of the distance between the object and light source

• Concentration's Effect on the Speed of Reaction Between Magnesium and Hydrochloric Acid

molecules there are the smaller the chance of them colliding with the solid magnesium ribbon. This means decreasing the concentration of hydrochloric acid slows down the rate of the reaction between the magnesium ribbon and hydrochloric acid. The diagram shows how fast acid molecules are colliding in a concentration of 50cm3 hydrochloric acid. There are less collisions with the magnesium ribbon (mg) in a concentration of 40cm3 acid and 10cm3 water than a concentration of 50cm3 acid and

I will connect the delivery tube to the measuring cylinder which is turned over which will be full with water. This is shown on my diagram. I will begin timing using a stopwatch and record the results every 10 seconds for 1 minute. I will use 0.5molar/dm3 to 3.0molar/dm3 of hydrochloric acid and record 3 sets of results and then I will take an average. Fair Test In order to
