...[pic] DATA COMMUNICATION THEORY LAB REPORT Report on Digital Transmission of Analogue Signals Pulse Amplitude Modulation INTRODUCTION: The experiment uses the L.J.Electronics Modicom-1 board to investigate the sampling of signals, and the filter effects on the reconstruction of the original signal from the sampled input. The sample/Hold operation is also investigated in this experiment. The Modicum -1 board allows an analogue signal to be sampled at a number of different rate(2kHz,4kHZ,8kHZ,16kHz,32kHz).The pulse width is varied in the steps of 0% from 0 to 90 of the sampling interval. Second order and fourth order low pass filter are available with cut-off frequencies set at 3.4 kHz. BACKGROUND: L.J.Electronics MODICOM-1 board is used to investigate the sampling of signals, and the effects of filter on the reconstruction of the original signal from the sampled input. In addition to this Sample/Hold operation is also investigated. [pic] MODICOM-1 board The MODICOM-1 board is considered as five different blocks namely 1.) Power Input 2.) Sampling Control Logic 3.)

...the transcript I will be able to investigate the theory of Katherine Nelson who stated, through her research and by logging children’s early language, words used can be placed in one of four categories with around 60% of those words being ‘naming words’ or nouns. By counting the number of nouns in short clips I will be able to determine if this theory is plausible. Theorist, Elizabeth Spelke said that of the nouns children know, the majority will be concrete nouns as they are logical and relate to objects they can see, hear, smell, feel and taste. By further exploring the types of nouns used by the children I aim to establish a link between both theories and see if they are still credible in today’s society. Methodology I am using an extract from ‘The Secret Life of Four Year Olds’, in order to use a non-biased selection. I will extract data to record the number of times in the running time of the programme the children use nouns compared to the number of words spoken. This quantitative approach will produce a solid basis from which I can further analyse the use of language in a statistical manner. However, when finally analysing these results, as this form of data collection is not contextualised and therefore will not show any of the more subtle language used by children. I also intend to compare the types of nouns used as a qualitative comparison. This investigation will help me conclude if Nelson and Spelke’s theories are...

...Derrick Chapman Jr. ITM501- Module I Case November 11, 2013 In review of my position on information overload, there would be no such overload if avenues such as the various social media outlets, informative readings with little or no credibility, and networking forums with no proven success records were not so heavily relied upon within organizations. The course background readings shed light on how social media is hindering the notions of the Data, Information, Knowledge, and Wisdom. Data is defined as unprocessed information, while information is data that has had a chance to be processed, and finally knowledge and wisdom is something that can be reflected upon (Green, P. 2010). If you are constructively processing the data that you are receiving you will be come a learning organization, possessing the attributes of knowledge and wisdom. A learning organization will be taught through experience or simply stated trial and error. Learning will maximize innovation, effectiveness, and performance, and this knowledge should be spread throughout the organization creating a very reliable, proven, and stable structure. From a personal perspective if your organizations structure is designed to support and manage information there should be no overload. There are endless consequences to information overload, especially when the overload is at the hands of social media technologies. Most of the technologies were designed with the expectations...

...MPE711: Global Trade and Markets ASSESSMENT GUIDE In both assessment 1 (presentation) and assessment 2 (written research article) you will be required to work in a group on the same research topic. Groups should consist of 3 to 4 individuals. Exceptions to this can be made for offcampus students if they can demonstrate difficulty in finding group members. You are free to form your own groups, whether through face-to-face contact or by using the ‘group formation’ forum on CloudDeakin. Ensure once your group is formed that you register it on CloudDeakin. You are required to finalise your group formation by the second week of trimester. GROUP WORK TIPS Your group will benefit from diversity. You are encouraged to form groups with a broad range of skills covering quantitative analysis, writing, editing skills and leadership skills. You should also try to form groups that cover diverse industry groups and cultural backgrounds. You should consider appointing a leader for the group. The role of the leader is to coordinate meetings and set deadlines. However, the group should still agree on decisions made by the leader and the group cannot expect the leader to bear responsibility for the group’s performance. At the initial stage, avoid assigning different tasks to each member. You are encouraged to work as a group, meaning you should first think about the project as a whole, write down some bullet points, and then meet together to work out a plan prior to the assigning of tasks...

...Unit 2 answers: 1. Outline the theory, concept or idea that formed the basis of your fieldwork investigation (aim): The fieldwork investigation took place upon the Glenderaterra Beck River and our aim was to measure and interpret how fluvial channel characteristics changed downstream at our stratified sampling sites in comparison to the Bradshaw Model. This model suggests that as you progress downstream, the discharge increases as erosion widens and deepens the channel. Velocity is also said to increase as tributaries input discharge into the river and friction plays a weaker role so the velocity increases. Load quantity increases additionally as erosion has caused the banks of the river to fall into the channel flow and the higher energy levels enable the river to carry a larger load. It also suggests that pebble roughness and gradient reduces as you progress downstream as lateral erosion comes into play and decreases the steepness of the gradient as well at attrition and abrasion smoothing the edges of rocks and pebbles. We also looked at the Hjulström curve as an additional theory in terms of energy in a river and how this determines whether a river will erode, transport, or deposit sediment. The graph takes sediment particle size and water velocity into account. The upper curve shows the critical erosion velocity in cm/s as a function of particle size in mm, while the lower curve shows the deposition velocity as a function of particle size. Note that the axes are logarithmic...

...relationship between data and information is an interconnected one. Data is raw facts such as phone numbers or addresses, and information is the organization of these raw facts into a meaningful manner. The information may be well organized on a report or table and yet not always be meaningful to all people. There are different ways to arrange data to make it meaningful for different people. For example, one person might be satisfied with information that shows him or her towns in which their customers live in to help him or her determine where the largest volume of customers are. A different person might want that information expanded to include those customers street addresses as well so that they may determine a better shipping route. Both of these examples contain the same customers and similar data but the first person would have no use for the street addresses in his search and the second person would not have enough information to create a shipping route from just the towns. The type of data used can also affect the information generated. You can gather a great deal of data on the needs of plants to grow but if you do not put the data in the table correctly or put inaccurate data in you will get information that is basically useless. That is the garbage in/ garbage out theory. It is also a good idea when creating a table to group the like characteristics together to make it easier to gather information from the data. Computers now make it easier to input data into tables in...

...understand within this paper. You can say that data and information do not have the same meaning although we use them interchangeably. When you receive data you have to put it through some steps in order for it to be considered information to be used by an organization or company. First you have to acquire the data. There are various ways to receive opinions of customers. This can be done by posting on social websites, emailing or having a customer respond to a survey after a telephone call with the corporation. After the data is received it has to be classified or identified. You can do this by choosing what types of data that needs to be classified such as account data, personal data or commercially valuable data. Another way to think of classifying data would be to have it broken into sections such as prohibited, restricted,00 confidential and unrestricted information. While classifying and identifying data it should meet certain confidentiality requirements. A plan must be put into place, maybe by a team, to sift through and find the desired data. The next step should be storage of the data. You definitely do not want just anyone to be able to access the data either. There should be a protocol set up so that only certain people can view all of the information. The first thing that needs to be done is to identify what information exists in your environment and who needs it and when. The reason for this is that not all data is equal. The security...

...mathematics that focuses on the organization, analysis, and interpretation of a group of numbers” (Aron, Aron, & Coups, 2009, p. 2). However, just the mention of statistics makes people nervous, although when properly understood, many of the questions statistics tries to answer are very provocative and challenging. Statistics are a collection of information and, data that helps test the theory something is happening or will happen again. The functions of statistics are there to help researchers have a better understanding of a phenomenon. Statistics can be used when looking for the truth, if you have ever had a hunch about something, was it confirmed? Yes the hunch was confirmed. Statistics help researchers with data by using math and working with a group of numbers. Statistics studies variables, characteristics that have different values, values, possible number that a score can have, and score one person value of a variable (Aron, Aron, & Coups, 2009). Descriptive and inferential statistics are to evaluate results and enable one to make a conclusion. Descriptive statistics are a way to describe data (Laird Statistics, 2013), as well as to “summarize and describe a group of numbers from a research study,” whereas, inferential statistics are used to “draw conclusions and inferences based on numbers from a research study” but go beyond those numbers (Aron, Aron, & Coups, 2009, p. 2). If one thinks of statistics as a tool instead of a mathematical issue, one...

Web data mining is a process in which knowledge and information is extracted from the web content resources will be basically it is a data mining process or technigue to crawl through different web pages to get the required information. One of the biggest problem on the web is the data on the web is semi-structure, irregular and it always keeps on changing and there is no unified fixed pattern for the data on the web. If the data on the web is considered on the database point of view the, each site has its own highly complex data source and also the information is not organized in the same way which makes the web a very big heterogenous environment. Since all most all the information on the current Web is still described in HTML format which can only be displayed in the browser rather than the one which is described with the web data meaning and data structure information, which makes it a bit difficult to mine the data from web efficiently and accurately....

...descriptive and inferential statistics. Statistics are used in almost every branch of study and is found behind the scenes in many of our normal daily activities. From economic to scientific studies, statistics are utilized in one way or another. Statistics are an essential part of understanding information and expanding knowledge base and is encompasses almost all aspects of enquiry ("7 Most Essential Functions Of Statistics", 2012). Statistics have many functions that we utilize;statisticsprovides for a better understanding of phenomenon of nature and helps in proper and statistical planning in all forms of study. Using statistics helps in collecting useful quantitative data and also aids in presenting difficult or confusing data in an understandable way. Statistics facilitate comparison amount different arrays of data and allows the information to be comprehended and used to facilitate a conclusion or solution. The use of statistics is also an important part of developing plausible hypothesis and allows for more valid inferences and more accurate forecasting of future issues or events. In other words, statistics are a part of everyday life in...
