Unit 8 Application 2 - Essay Example The exit of a manager must be categorised as downsizing, voluntary or discharge exit so that the calculation of turnover rates in the end becomes possible. Factors contributing to leaving HCLC may be low motivation or external factors in relation to what HCLC offer. It is important to analyse so that the organisation knows what managers are going for that is not being offered (Heneman, Judge and Kammeyer-Mueller, 2012). The organisation may fail to retain some of those valuable managers unless we are concerned about the issue. A higher turnover may be faced in the future if we do not address the issues in the present. This may spoil the image of the organisation such that getting contracts may become problematic. Managers who are leaving may leave with other employees leading to reduced performance and indiscipline. Later, it may be hard to find, attract or hire managers with value. HCLC should look at the basis upon which the managers have left the organisation in the previous year. It is important to find out how long they worked in the organisation and how they were managing their positions. (Harris and Brannick, 1999) It would be very wise to interview those managers who have quit knowing the major reasons of managerial turnover. Sometimes employees are said to quit their bosses but not their job. This is a result of the kind of relationship between managers and their bosses (Gully and Phillips, 2010). Proper research and collection of data on relationships that managers share with operations manager should be conducted. Benefits and costs resulting from managerial turnover should be conducted. Categories of cost should be known in terms of training, replacement and separation and all financial non-financial costs estimated. Benefits must be weighed in association with costs of managerial turnover. This information will

Computer Graphics - Essay Example [Wallace, 2001. pp3-6] The JPEG compression algorithm involves three stages - Colour Space Conversion (Red-Green-Blue triplets mapped to Luminance-Chrominance Blue-Chrominance Red triplets), Segmentation into 8x8 pixel blocks, and Discrete Cosine Transformation (image transformation from spatial domain to frequency domain representation) encoding stage that includes Quantization (sorting the output waveform of DCT), Zigzag Scan (sorting the frequency coefficients from low to high), and Entropy Coding (Huffman Coding and Arithmetic Coding). The encoding and decoding algorithms for JPEG images are shown in figures 1 and 2 respectively. Compression is used to reduce the file sizes such that they can be used on web pages or documentation or any other light weight graphics applications. The 8x8 blocks of source images are first shifted from unsigned integers to signed integers and then are applied to the Forward Discrete Cosine Transformer (FDCT). To decode the compressed image to achieve the 8x8 blocks again, they are applied to the entropy decoder whereby the output is taken out from Inverse Discrete Cosine Transformer (IDCT). The final processing step of DCT encoder is the entropy coding that achieves additional compression by encoding the quantized DCT coefficients based on statistical characteristics. There are two types of Entropy Coding methods - Huffman coding and Arithmetic coding. Huffman coding requires one or more sets of Huffman code tables whereas Arithmetic coding doesn't require any external tables (althoug h statistical conditioning tables as inputs can improve coding efficiency). The quantization stage of JPEG algorithm results in loss of information, thus making JPEG standard a lossy compression technique. [Wallace, 2001. pp3-6] Compression Ratios and JPEG image formats: Compression is specified in terms of bits per pixel including the chrominance and luminance components) called the compression bit rate. Higher the value of bits per pixel, better would be the image quality. The JPEG standard recommends the following mapping of image quality with bit rates in colored images having moderately complex scenes: 0.25 to 0.5 bits per pixel: The output image shall possess moderate to good quality 0.5 to 0.75 bits per pixel: The output image shall possess good to very good quality 0.75 to 1.5 bits per pixel: The output image shall possess excellent quality 1.5 to 2.0 bits per pixel: The output image shall be practically non-distinguishable from the original image The improved version of original JPEG technology is JPEG 2000 that provides better rate
