...Part 2: The Change Analysis -Images of Change This part of the project was asking us to analysis the image of Change within the two companies that choice to compare and contrast. While researching the information on Disney and Pixar, I came across some differences between Steve Jobs and Michael Eisner regarding how the two companies will work together. Going through the articles that I have read through they all show that Disney and Pixar has always been competing against each other on who can make the best animated motion picture. Here is a little history Disney has always been about producing animated features and live-action movies and as for Pixar they have always produced computer-animated movies. In this paper I will be talking about the Image Change, basis of image, application to Company #1, Company #2, pressures for change, differs from others how and the unintended consequences from Image. Lets begin with the three Images; I choose Director, Navigator and Nurturer. The reason that I choose these three is because of the people that were involved with this merge. There was Steve Jobs who was the President of Pixar and Michael Eisner who was the Chief Executive Office for The Walt Disney Company in 2005, Einser resigned and Robert Iger took his place. These three men I put them down under Director, because they were the ones who were in charge of executing the changes between the two companies. Next is Ed Catmull and David Stainton who were are in charge of making...

...1. Why might an organisation wish to carry out a PEST analysis? What are the four key components of a PEST analysis? How does a PEST analysis help to provide a picture of the challenges facing Jessops? This case study reviews the external factors that have had an impact on Jessops’ operations and strategy. It shows how managers study the company’s external environment through a PEST analysis. This involves identifying the political, economic, social and technological factors in the external environment that could impact on the business. This information is then used to assess the company’s current position within the market. The findings of the PEST analysis can be used by the board of directors to reassess business strategy and tactics. The board will decide what changes should be made to business operations to respond to external environmental changes. In this way, through carefully analysing the political, economic, social and technological changes in its external market, Jessops has been able to develop new business opportunities. 2. What has been happening to margins at Jessops? How have these margins been affected by changes in the economy, and by changes in competition in recent years? Jessops has been a leader in the photographic business for over 75 years. The Jessops story began in 1935, when Frank Jessop opened a photography store in Leicester.

Cohen1, Christopher Bjornsson1, Ying Chen1, Gary Banker2, Ena Ladi3, Ellen Robey3, Sally Temple4, and Badrinath Roysam1 1 Rensselaer Polytechnic Institute, Troy, NY 12180, USA, 2 Oregon Health & Science University, 3181 SW Sam Jackson Park Road, L606, Portland, OR 97239, USA 3 University of California, Berkeley, Berkeley, CA 94720, USA 4 Center for Neuropharmacology & Neuroscience, Albany Medical College, Albany, NY 12208, USA ABSTRACT An algorithmic information theoretic method is presented for object-level summarization of meaningful changes in image sequences. Object extraction and tracking data are represented as an attributed tracking graph (ATG), whose connected subgraphs are compared using an adaptive information distance measure, aided by a closed-form multi-dimensional quantization. The summary is the clustering result and feature subset that maximize the gap statistic. The notion of meaningful summarization is captured by using the gap statistic to estimate the randomness deficiency from algorithmic statistics. When applied to movies of cultured neural progenitor cells, it correctly distinguished neurons from progenitors without requiring the use of a fixative stain. When analyzing intra-cellular molecular transport in cultured neurons undergoing axon specification, it automatically confirmed the role of kinesins in axon specification. Finally, it was able to differentiate wild type from genetically modified thymocyte cells. Index Terms: Algorithmic information...

...can be done with wavelets that cannot be done with traditional Fourier analysis. Stephane Mallat was not the father of wavelet theory, but he is certainly an evangelist. His textbook on the subject, A Wavelet Tour of Signal Processing [1], contains proofs about the theory of wavelets, and a summation about what is known about them with applications to signal processing. One of his many papers, Characterization of Signals from Multiscale Edges [2], is frequently cited as a link between wavelets and edge detection. Mallat’s method not only finds edges, but classifies them into different types as well. Mallat goes on to describe a method of recovering complete images using only the edges, but we will not implement it in this project. In this project, we study this paper, and implement the method of Mallat to multiscale edge detection and analysis. We will first present a short background on wavelet theory. Then we will describe the different types of edges that exist in images, and how they can be characterized using a Lipschitz constant. Next, we describe the algorithm for the wavelet transform, from the Mallat paper. Finally, we show the results of applying the algorithm to a test image, and a real image. wave with the signal. When the results high valued, the coefficients of the Fourier transform will be high. Where the signal or the wave is close to zero, the coefficients will be low. Fourier analysis has a big problem, however. The sine and cosine functions are defined from...

...Globally forests contain 90% of the total vegetative carbon and 80% of the soil carbon and they assimilate 67% of the total terrestrial carbon dioxide (CO2) sequestered from the atmosphere (Landsberg and Gower, 1997). Hence this process is very essential in mitigating the global climate change. However this carbon is release into the air once the trees die from disease or cut down. The Advanced Very High Resolution Radiometer (AVHRR) Normalized Difference Vegetation Index (NDVI) is indicating a continuous disturbance in the forested area of Wisconsin and Minnesota (Neigh et al., 2008). Although a number of recent studies have found marked variations in NDVI throughout the Northern Hemisphere, they have not attributed these changes to regional factors that may include natural disturbances and/or human alterations to ecosystem functioning ([Gong and Shi, 2003], [Slayback et al., 2003], [Tucker et al., 2001] and [Zhou et al., 2001]). It is important to identify and quantify land cover type, because changes in land cover can alter ecosystem functioning and carbon storage ([Baldocchi and Amthor, 2001] and [Olson, 1975]). NDVI (Tucker, 1979) is calculated from channel 1 (0.58–0.68 μm) and channel 2 (0.72–1.10 μm) from the NOAA AVHRR series of polar orbiting satellites as: NDVI has been found to have a strong linear relationship to the fraction of...
