results can vary dramatically. what a scale-free network is Scale free Networks are ones that have no average or typical nodes but have hubs and are non-random networks‚ which uses power law distributions. An example of a Scale free network is a computer network‚ which has users and user stations and hubs to interact which each other to provide a complex network. This type network uses computer protocols as its Power law distribution. Therefore‚ Scales free networks all have set Rule or laws

Taken together‚ these time spans make up the geologic time scale. The Geologic Time Scale Structure of the Time Scale Eons represent the greatest expanses of time. Eons are divided into eras. Each era is subdivided

Earthquakes are measured using observations from seismometers. The moment magnitude is the most common scale on which earthquakes larger than approximately 5 are reported for the entire globe. The more numerous earthquakes smaller than magnitude 5 reported by national seismological observatories are measured mostly on the local magnitude scale‚ also referred to as the Richter scale. These two scales are numerically similar over their range of validity. Magnitude 3 or lower earthquakes are mostly almost

Measurement: Earthquakes are measured with the help of seismometers. The moment magnitude is the most common scale on which earthquakes larger than approximately 5 are reported for the entire globe. The more numerous earthquakes smaller than magnitude 5 reported by national seismological observatories are measured mostly on the local magnitude scale‚ also referred to as the Richter scale. Magnitude of concern: Magnitude of 3 or lower earthquakes are mostly almost imperceptible and magnitude

The most known region that was affected by an earthquake on a massive scale was located in the region of Eastern Sichuan‚ China. The earthquake magnitude was recorded as peaking at a 5.0 on the rictor scale. Would you be willing to live in one of the red areas on the map? Explain. I would not want to live in any of the red areas associated with common earthquake activities. The red

Making Research Decisions Rating Scales As a researcher‚ one must choose which rating scale is going to be the most effective method. Once choosing the scale‚ he/she then must decide the amount of choices the subject has. We are going to explore four different scales: 1. Yes/Depends/no‚ 2. Excellent/Good/Fair/Poor‚ 3. Excellent/Good/Average/Poor‚ and 4. Strongly Approve/Approve/Uncertain/Disapprove Strongly Disapprove. I believe that the yes –maybe-no scale is somewhat week unless used in
