Grief and Shock, Discernment and Dificulties, Their Reasons and Motives in the Light of the Teachings of the Holy Prophet (PBUH)

Islam has this faith that everything of the universe, small or big has come into existence with the will, power, method and knowledge of Allah. Fate is the attribution of Allah, which is the truth. It is the condition to have belief of this faith. Since, faith is the attribution of Allah and it’s impossible for anyone to know the extent of godly attributions, so the issue of fate is delicate and precise. One must only have the faith that whatever is happening in the world was already in the knowledge of Allah and god has already saved it on the safe tablet. The dilemma of fate has not been solved by anyone and it will never be solved. There must be a simple faith that whatever is happening in the world has already known by Allah as the Creator of everything is God and everything has come into existence with His creation. All the matters happening in the world are of two kinds. In some of them the will and authority is prevail. In these matters which are to be done which are not to be done orders of their execution or prohibition are given. If they are not performed because of will and authority, there will be accountability for them. Secondly, all those works which have the order of not to be performed, it is necessary not to perform them with one’s will and authority. If those works are not avoided, one must be accountable for them. There are some other works which do not involve our will and authority so, whatever happens is according to our fate. The works having our will and authority for performance will be rewarded and punished accordingly. This study explores the reasons of grief, shock, discernment and difficulties, their reasons and motives in the light of teaching of The Holy Prophet.

Diagnostically Lossless Compression of Medical Images

Medical images are very important for diagnostics and therapy. However, digital imaging generates large amounts of data which need to be compressed, without loss of relevant information, to economize storage space and allow speedy transfer. In this research three techniques are implemented for medical image compression, which provide high compression ratios with no loss of diagnostic quality. Different image modalities are employed for experiments in which X-rays, MRI, CT scans, Ultrasounds and Angiograms are included. The proposed schemes are evaluated by comparing with existing standard compression techniques like JPEG, lossless JPEG2000, LOCOI and Huffman Coding. In a medical image only a small region is diagnostically relevant while the remaining image is much less important. This is called Region of Interest (ROI). The first approach compresses the ROI strictly losslessly and the remaining regions of the image with some loss. In the second approach an image is first compressed at a high compression ratio but with loss, and the difference image is then compressed losslessly. Difference image contain less data and is compressed more compactly than original. Third approach exploits inter-image redundancy for similar modality and same part of human body. More similarity means less entropy which leads to higher compression performance. The overall compression ratio is combination of lossy and lossless compression ratios. The resulting compression is not only strictly lossless, but also expected to yield a high compression ratio. These techniques are based on self designed Neural Network Vector Quantizer (NNVQ) and Huffman coding. Their clever combination is used to get lossless effect. These are spatial domain techniques and do not require frequency domain transformation. i An overall compression ratio of 6-14 is obtained for images with proposed methods. Whereas, by compressing same images by a lossless JPEG2K and Huffman, compression ratio of 2 is obtained at most. The main contribution of the research is higher compression ratios than standard techniques in lossless scenario. This result will be of great importance for data management in a hospital and for teleradiology.
