into smaller channels called subchannels. There are many types of multiplexing, for example, time division multiplexing, statistical multiplexing, and etc. The types that are used depends on what the media, transmission, and reception devices can handle. A multiplexer transmits at the end of a channel and demultiplexers are at the receiving end separating the combined signals and restores them to their original form. Multiplexing also comes in hand with networking to increase the data that is sent
that I had a genuine interest to applying mathematical and statistical theories to real-world concerns. Hey, even Twain the skeptic realized the importance of balancing the cargo on shallow, difficult-to-navigate riverboats so that the port and starboardsides were equally laden-he even advised the captains to part their hair down the middle so that the weight was perfectly distributed!
Dense wavelength division multiplexing (DWDM) is a technology that puts data from different sources together on an optical fiber, with each signal carried at the same time on its own separate light wavelength. Using DWDM, up to 80 (and theoretically more) separate wavelengths or channels of data can be multiplexed into a light stream transmitted on a single optical fiber. Each channel carries a time division multiplexed (TDM) signal. In a system with each channel carrying 2.5 Gbps (billion bits per
features such as closed subscriber group, self-organising networks, location services, enhancement cell ID and Multimedia Broadcast services this is a standard which pretty much became the norm. Technologies such as Orthogonal Frequency Division Multiplexing (OFDM) and Multiple-Input Multiple-Output(MIMO) which were instrumental in the evolution to the LTE-Advanced are also discussed. scalable multiple transmission bandwidths are supported by LTE including one for the packet-switching (PS) mode.
Statistical Investigation For my Maths GCSE's I am required to do two pieces of coursework one of which is a piece on statistics. The purpose of this project is to help me investigate a real life situation using statistics. In this case I have been given some quantitative data on the end of year maths test scores of children in year 8. What I am supposed to do is compare the data by making hypotheses to indicate if there is something comparable between the results. First I have decided
Statistical Investigation Introduction I have chosen to do this statistical coursework that uses data from 'Mayfield High School.' Although this is a fictitious school, the data is based on a real school. As the data has been collected for me, it is called secondary data. I believe that this coursework will allow me to illustrate my ability to handle data, use specific techniques and apply higher level statistical maths by being able to use a variety of methods in order to analyse
Statistical Investigation on Car Prices Data Collection: We are asked to find the relationship between prices of ‘51 registered’ cars and variables such as their current new price, mileage and weight by using the regression analysis. To collect full information of these registered cars, we can access to the websites like: http://www.exchangeandmart.co.ukHowever, in this easy, we use the data, which are provided with the assignment by our teachers. By the sources, 100 cars, which
Statistical Investigation Into Height and Weight of Students My hypotheses are as follows: ~ 1. Year 11 students are, on average, taller than year 9 students. 2. There is better correlation between height and weight in year 7 than there is in year 11. 3. The taller someone is the heavier they are. Below are the sampling methods that I have used in my coursework: Stratified Simple Random Stratified sampling can be defined as the process where the population is divided into
Statistical Investigation All graphs should be attached. An Investigation into the Relationships between the Heights and Weights of a Rangeof Studentsat Mayfield High Aim I aim to investigate the relationship between the heights and weights of a range of students from different demographics at "Mayfield High". Prediction I. I predict initially that the average male height will be greater than the average female height. That is due to biology stating that males are, on average
Statistical Investigation into Rollercoaster Data I am going to be completing a statistical investigation from some collected data. This will be obtained from a World Rollercoaster Database. The information that can be seen from the database about an individual rollercoaster is: which country designed it, when it opened, its height, its length, its max speed, the ride time, and the thrill factor out of 10. I am going to investigate whether the fastest rides are the most exciting. I would
measurements that was recorded, human error and past injuries would influence the data. This is why .002 (alpha number) is going to be calculated in with the data. Dependent t-test, independent t-test, mean and standard deviation are the following statistical analysis that is used in the following
A. Purpose of the Study “Reading is the motivated and fluent coordination of word recognition and comprehension” (Leipzig 2001). In the educational system, pupils are encourage to read books because of the belief that one becomes better at a skill based on the amount of time dedicated to that particular skill. Pupils must practice the skill learned and receive “frequent feedback (Samuel and Wu).” Practice is most effectual when it is individualized and accompanied with instruction (Renaissance
Studies of the disease were found by using the Texas A&M Corpus Christi library through electronic search of temporal lobe epilepsy. Four primary research and one review article were used to complete this literature analysis. The articles discussed are condensed in Table 1. Regarding EI in patients with TLE and patients with extra temporal lobe epilepsy was a case-control study that had three groups. Group 1 consisted of forty patients with TLE. Group 2 consisted of thirty patients with extra temporal
Peer-Assisted Learning Strategies (K-PALS) for students with disabilities. Additionally it looked to see if there was a correlation between the amount of training the teacher received and the students’ success. The team of authors used a variety of statistical methods to determine the effectiveness in both of these areas. A random group of 89 kindergartners, from 47 different classrooms in Minnesota schools all with individualized education programs, were divided into three different test groups. These
Humans are curious creatures who may very well feel the urge to disregard exact orders. This drive is often encouraged by feelings of boredom or often because we cannot limit ourselves to more knowledge. The objective of this study was to observe curiosity between males and females. We evaluated female “peekers” against male “peekers” and female “non-peekers” against male “non-peekers.” A box visible enough to get attention from participants was decorated, a hole was cut on the top and a sign was
This study looked at the role of sports in inhibiting the development of early social anxiety symptoms in children between 7 and 8 years old. With multiple hypotheses the researchers hoped to show that exercise and sports will have an anti-anxiety effect on this specific (social) form of anxiety. The specific hypothesis were as follows: children who participate in extracurricular sports should have less social anxiety symptoms one year later than a child practicing no sports, children on a team sport
One of the earliest models investigating attention was developed by Broadbent (1954, 1971 cited in Edgar 2007) who considered that incoming information on different sensory "channels" was selectively filtered and that only one stream could be semantically processed at a time. This model typified the "bottleneck" approach to selective attention. His work focused on filtering and the early stages of processing. The bottleneck operates by filtering out sensory information on the basis of physical characteristics
On Tuesday in lab, we wanted to measure the velocity and acceleration of a ball rolling down an incline. To do this, we made our table have an incline by putting wood blocks under two legs of the table. We placed meter sticks on a table so we could determine the distance the ball traveled for a certain amount of time. We placed the ball at the 0cm mark on the meter stick and let go of the ball so it could roll down the table. To make our results more accurate, we videoed the ball rolling down the
experience and will probably develop PTSD or ASD, there is no precedent for how to treat them. The only tool that can be used at these times is the Diagnostic and Statistical Manual (DSM), to classify the disorder. No real solution exists for a treatment process for an incident of this scale. The three journal articles I will be using show statistical data about how people dealt with these experiences and what percent of them developed PTSD or ASD. They also show how many people showed signs of these disorders
This experiment would be considered a fair test as the variables were controlled; the same ball in the same condition was used, it was dropped from the same height each time, no additional external force acted upon it and the accuracy of the readings were consistent. However there were a few minor elements which may have altered the results such the test no being done on the different days. This would have had a minor effect as the temperature alters the elasticity of rubber and causes wood and concrete
