A very large quantity of data which traditional applications fail to process, leads the world to the era of Big Data. With the increase in opportunity and technology scope, Big Data also leads to many challenges such as data capture, storage, transfer, update, analysis, sharing, search, visualization, privacy of data etc. In order to deal with all these challenges there is a need of proper framework which will not only process the data but also provide a meaningful analysis so as to take proper decision in critical situations either related to industry, healthcare, social network, science, telecom, environment, business etc. The contribution of this paper is to analyze literature related to Big Data & Hadoop framework and provide architecture to process Graph Data. Additionally, it provides online source code in order to understand big data for beginners.

There is a dearth of high quality reconfigurable hardware for DWT which can be extensively used in various real time signal and image processing applications. In this article, we have focused on proposing a dedicated customizable hardware for DWT applicable to 1D/2D signal processing. We have proposed bit-serial distributed Arithmetic (DA) based VLSI architectures for ID/2D DWT. Exploitation of DA enables us to make our designs Multiplierless, thereby consuming less area. Bit serial configuration of DA is also exploited to introduce modularity and pipelining in the proposed convolution DWT based 1D/2D architectures. Though the speed of the proposed designs may not be suitable for certain applications, a number of parallel channels can be introduced for the same. The provision of mode selection can efficiently be used to realize 9/7 and also 5/3 DWT filters in the same proposed architecture. In the proposed 1D/2D architecture, we have achieved about 50% memory size reduction, 30% reduction in area consumption and comparable speed in comparison to the other latest notable DWT architecture so far. We have verified the viability of our proposed 2D architecture by utilizing it in real time image decomposition.

Dealing with freeway bottleneck sections in ramps is hot research topic in most country. A traffic control model is built after dividing highway management units. New concept of regulating density is given after analyzing data. The conclusions are obtained after numerical calculation, that is: before vehicles entering the bottleneck sections, density and speed of vehicles should be controlled. This conclusion is helpful for further research of intelligent transportation system.

Considering the intelligent transportation system with fixed phase sequence of fuzzy control, a fuzzy model of control algorithm with variable phase sequence is built. The fuzzy control algorithm is discussed. This paper designs green light controller for the delay time and the phase selection controller, then stimulates the process and analyzes the conclusion. Compared with the traditional control method, the optimization effect is remarkable. The numerical results are better then the one of traditional control method, and is helpful to further design and study the intelligent transportation system.

In this paper we consider the problem of programming for heterogeneous computer systems consist of CPUs and various accelerating devices such as GPUs. We introduce a few of the most popular models for heterogeneous parallel programming, including OpenCL (Open computing Language), CUDA (Compute Unified Device Architecture), OpenACC, OpenHMPP (Hybrid Multicore Parallel Programming), C++ AMP (accelerated massive parallelism), HPL (Heterogeneous Programming Library), etc.

In this information era, it is difficult to exploit and compute high-amount data efficiently. Today, it is inadequate to use MapReduce to handle more data in less time let alone real time. Hence, In-memory computing (IMC) was introduced to solve the problem of Hadoop MapReduce. IMC, as its literal meaning, exploits computing in memory to tackle the cost problem which Hadoop undue access data to disk caused and can be distributed to perform iterative operations. However, IMC distributedcomputing still cannot get rid of a bottleneck, that is, network bandwidth. It restricts the speed of receiving the information from the source and dispersing information to each node. According to observation, some data from sensor devices might be duplicate due to time or space dependence. Therefore, deduplication technology would be a good solution. The technique for eliminating duplicated data is capable of improving data utilization. This study presents a distributed real-time IMC platform - "Spark Streaming" optimization. It uses deduplication technology to eliminate the possible duplicate blocks from source. It is expected to reduce redundant data transmission and improve the throughput of Spark Streaming.

In this paper, we study the customer loyalty based on survival analysis. We regard the time of using product as the survival time, and utilize the AFT model to analysis the influencing factors of the customer loyalty. The results of simulation show that our method is more effective than commonly regression method. A real example is also provided as an illustration.

The implied volatility is an important parameter when the trader need to quote the prices of options. The famous B-S Model assumes that the implied volatility surface is a constant independent of the option's strike and time to maturity. But empirical analysis has proved that implied volatility surface is a non-flat function. There are several popular methods to construct the implied volatility surface. In this paper, the parameter affection and performance of several models are compared and tested by using empirical analysis.
