Patrick Cunningham ITM220-J November 8‚ 2013 Big Data Big Data‚ an inspirational novel about the collection and processing of massive amounts of data was eye-opening and encouraging. This collection of data over a long period of time has been processed and used towards many different aspects throughout the world. Dilemmas such as tracking the H1N1 virus‚ to buying the most inexpensive plane tickets‚ all the way to predicting dangerous manholes explosions have all been processed and tabulated

Data Collection Methods OBSERVATIONS Observation is a primary method of collecting data by human‚ mechanical‚ electrical or electronics means with direct or indirect contact. As per Langley P‚ “Observations involve looking and listening very carefully. We all watch other people sometimes but we do not usually watch them in order to discover particular information about their behavior. This is what observation in social science involves.” Observation is the main source of information in the

Note that an infinite number of higher frequencies of decreasing magnitudes is needed to represent the single pulse. What implication does that have for a real digital transmission system? Suppose that a digitised TV picture is to be transmitted from a source that uses a matrix of 480 x 500 picture elements (pixels)‚ where each pixel can take on one of 32 intensity values. Assume that 30 pictures are sent per second. (This digital source is is roughly equivalent to broadcast TV standards that have

Observation: Researches have shown that trauma has long-term negative effect on physical and mental health‚ such as diabetes and heart disease. It also leads to the formation of personality and individuals with certain traits may have stronger reaction to experience of trauma. According to a study that was conducted in the US‚ women who reported physical childhood abuse‚ not mental abuse‚ had double the risk of having metabolic syndrome. In another words‚ all forms of trauma have different effects

lab‚ it was decided to compare the concentration of new Publix brand hydrogen peroxide to an old sample of the same solution. From the data collected in the first part by titrating a solution of FeSO4*7H2O with the KMnO4 solution‚ it was determined that the concentration was .028M MnO4-. This was able to be done because a known amount of FeSO4*7H2O was in the solution‚ from this‚ when it is completely titrated by the KMnO4 it is possible to find the molarity of the MnO4- used by measuring the amount

Methods/Procedures To test the original hypothesis‚ six observations were taken at many different times during the day. Observations were taken during the morning‚ mid-afternoon‚ and the evening. The data was collected on four different days. To make sure that the observations would be consistent and accurate‚ two sets of observations were taken around in the same time frame. The location and the weather were constant‚ while the time of day was altered since it was the variable that was being tested

DATA INTEGRATION Data integration involves combining data residing in different sources and providing users with a unified view of these data. This process becomes significant in a variety of situations‚ which include both commercial (when two similar companies need to merge their databases and scientific (combining research results from different bioinformatics repositories‚ for example) domains. Data integration appears with increasing frequency as the volume and the need to share existing data explodes
