Risk Assessment is one of the most critical parts of software engineering process, and risks are the factors that could be results in software failure if they are not correctly handled. In this Paper, we propose a solution to reduce risks using UML visualization of software processes in detail, and V-Model (Software Development Lifecycle Model) techniques are performed to produce verified results in each phase of development lifecycle. Using all above aspects and research findings, we propose “Risk Assessment V-Model”. Furthermore, we use “Do Sale Process” to discuss different properties of our model. This model is quite in general and can be applicable and expendable for many kinds of software systems.

In order to improve the intelligence, high efficiency, humanization of the type of the search and eliminate games, and also to improve the search performance and rule out the accuracy of the target during intelligent games running. This paper puts forward a comprehensive method that combines Genetic Algorithm, Neural Network and Back Propagation (BP) to solve the insufficiency of computing power and low efficiency by using a single algorithm in Intelligence games. In this method, Genetic Algorithm will be used in weight training of Neural Network first of all. It will not stop iterating until Genetic Algorithm evolves into a certain degree or network errors satisfies the requirements, and delivers the best chromosome we get to Neural Network. Then BP trains the data that runs through the Neural Network, which is Neural Network's second training. Finally, the paper applies the new way in the Mine Clearance experiment. By comparing this experiment with only using Genetic Algorithm or Neural Network, it finds out that the proposed method significantly improves the minesweepers accuracy.

Cognition, a basic concept in psychology, is the set of a human's inner mental activities and processes related to knowledge. Actually it is possible to introduce cognition into engineering systems to construct intelligent systems with human cognitive functions. Cognitive radar is such a successful case that improves the working performance in complex environment. The article starts with the concept of cognition and cognitive radar, subsequently followed by the basic elements including intelligent information processing, information feedback. The fundamentals about how cognition increases the perceptual ability of radar are discussed in detail.

Cloud computing suffers from a number of problems in terms of security issues. Authentication and integrity play an important role in the security field and numerous concerns have been raised to recognizeor protect any tampering with exchanges of text between two entities (sender and receiver) within the cloud environment. Many schemes in this area can be vulnerable to well known methods of attack such as replay attack, forgery attack, dictionary, insider, and modification attacks. A robust scheme is therefore required to detect or prevent any modification or manipulation of a message during transmission. In this paper, we propose a new message authentication code (MAC) based on feature extraction of the user's iris in order to assure the integrity of the user's message. Features are extracted from the user's iris to generate a message code for each user's login and to prohibit malicious attacks such as replay, forgery and insider attacks. Our proposed scheme enjoys several important security attributes such as a user's one time bio-key, robust message anonymity, data integrity for a user's message, phase key agreement, bio-key management,and one time message code for each user's session. Finally, our security analysis and experimental results demonstrate and prove the invulnerability and efficiency of our proposed scheme.

The concerns of data-intensiveness and energy awareness are actively reshaping the design of high-performance computing (HPC) systems nowadays. The Graph500 is a widely adopted benchmark for evaluating the performance of computing systems for data-intensive workloads. In this paper, we introduce a data-parallel implementation of Graph500 on the Intel Single-chip Cloud Computer (SCC). The SCC features a non-coherent many-core architecture and multi-domain on-chip DVFS support for dynamic power management. With our custom-made shared virtual memory programming library, memory sharing among threads is done efficiently via the shared physical memory (SPM) while the library has taken care of the coherence. We conduct an in-depth study on the power and performance characteristics of the Graph500 workloads running on this system with varying system scales and power states. Our experimental results are insightful for the design of energy-efficient many-core systems for data-intensive applications.

This paper describes a strategy to optimize small file's reading and writing performance on traditional distributed file system. Traditional distributed file system like GlusterFS stores data within local file system (XFS, EXT3, EXT4, etc.), which shows a significant bottleneck on file metadata lookup. We try to re-design metadata structure by merging small file into large file, thus to reduce size of metadata, so we can store the whole files' metadata inside main memory. We design and implement the whole strategy on GlusterFS, test results show a great performance optimization on small file operation.

We study the verifiable delegation of set intersection in the model of authenticated data structures, where a weak client in storage and computation stores its dataset composed of some sets into a powerful server. The client can issue update and set intersection query over outsourced data. The server returns the result and a proof of its correctness. Our scheme allows any entity to publicly verify the correctness of set intersection query, and requires no secret key. Based on characteristic polynomials of sets, our authenticated data structure firstly provides a practical and specific method for set intersection through polynomial evaluations. It achieves optimal verification and proof complexity, as well as optimal update complexity without bearing any extra space overhead. The overhead for computing actual answer and proofs is reduced significantly in contrast with previous methods based on bilinear-map accumulators. The intersection query comes up in keyword search, database queries and other applications. Indeed, our scheme can be effectively used in such scenarios. The security of our constructions is based on co-Computational Diffie-Hellman assumption.
