Medical Imaging is currently a hot area of biomedical engineers, researchers and medical doctors as it is extensively used in diagnosing of human health and by health care institutes. The imaging equipment is the device, which is used for better image processing and highlighting the important features. These images are affected with random noise during acquisition, analyzing and transmission process. This results in blurry image visible in low contrast. The Image De-noising System (IDs) is used as a tool for removing image noise and preserving important data. Image de-noising is one of the most interesting research areas among researchers of technology-giants and academic institutions. For Criminal Identification Systems (CIS) & Magnetic Resonance Imaging (MRI), IDs is more beneficial in the field of medical imaging. This paper proposes algorithm for de-noising medical images using different types of wavelet transform, such as Haar, Daubechies, Symlets and Biorthogonal. In this paper noise image quality has been evaluated using filter assessment parameters like Variance, Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR). It has been observed form the numerical results that, the performance of proposed algorithm reduced the mean square error and achieved best value of peak signal to noise ratio (PSNR). In this paper, the wavelet based de-noising algorithm has been investigated on medical images along with threshold.

The previous electronic sealed-bid auction schemes usually have a common drawback, the third party (auction host) can conspire with a malicious bidder to leak all bidding prices before the opening stage. It results in the malicious bidder wining the auction with an optimal bidding price. This paper proposes a sealed-bid auction scheme without third party to get over this drawback. The proposed scheme adopts the ideal of the conditionally anonymous ring signcryption to guarantee the secure requirements of sealed- bid electronic auction.

Grammar induction has received a lot of attention from researchers in the past decades because of its practical and theoretical impact on data compression, pattern discovery and computation theory. There are a bunch of grammar induction algorithms for a given sequence are introduced. Most existing work on learning grammar for a given sequence is based on deterministic approach. Such deterministic approaches used by grammar induction algorithms can be categorized as greedy heuristics. In addition, there are many grammars, which can be learned from a given sequence. The smallest grammar problem is defined by some researchers to evaluate different grammars learned from a given sequence by different algorithms. Such problem is proved as NP-hard. In this work, we introduce a nondeterministic approach to address grammar induction for a given sequence based on genetic algorithm. We demonstrate that our grammar induction algorithm can effectively identify smaller grammar than a well-known grammar induction algorithm. Experimental results, which are presented, illustrate that our approach and algorithm are feasible to resolve difficult problems such as identifying patterns of DNA sequence.

The time synchronization among simulation federates could be realized through logical time by traditional time management of distributed simulation. There are two types popular time management of distributed simulation based on logical time, conservative time advance mechanism and optimistic time advance mechanism. Conservative time advance mechanism restricted the causal relationship between simulation federates and might lead to poor simulation efficiency and deadlock while the difficulty in rollback might exist in optimistic time advance mechanism. Based on the vector time, an optimistic time managing mechanism was put forward, the updating algorithm of vector time was introduced and the rollback control based on vector time was researched. The application in intelligent detection simulation system of carrier rockets demonstrated that in the environment of small number federates, the algorithm could control rollback storm effectively and would show high efficiency and reliability.

Recently, cloud computing is increasingly becoming the focus of attention at home and abroad. When the big data storage is become the core of cloud computing system, cloud computing system would evolve into a cloud storage system. With rapidly development of cloud computing, cloud storage has become one of most popular research field. HDFS (Hadoop Distributed File System) has a powerful data storage capacity for cloud storage system. However, it must be improved before applied to large scale since it exists some drawbacks during the design process. This paper researches the cloud storage model based on HDFS, solves uneven replica distribution.

After analyzing the motion area of flame blocks and fluctuations of flame pixels in complex scenes video, this paper detects motion area by using blocks in spatial consecutive video frames. For the color information of the flame block, motion area is analyzed by the second order color moments in HSV color space, and then it extracts the suspected flame color motion area. For each pixel of the block area, this paper chooses spatial continuous images to do wavelet analysis and extracts pixels which meet the flame fluctuation rules as the flame pixels. Use local weighted operator to filter out non-flame discrete pixels, make the adjacent flame pixels area form connected areas and give an alarm. Experimental results show that this method can detect the video flame area taken by ordinary video cameras quickly and give an alarm, meanwhile, it also has a better robustness.

Ambient occlusion is an illumination simulation approach used in ray tracing for decades. However, huge consume of multiple sample times, for a high re-solution, in ambient occlusion restricts its development. We propose an algorithm decreasing the sample times with adjacent pixels shared information in sampling process. By introducing this nova approach, we get a big improvement when comparing to previous methods.
