Cat Swarm Optimization Algorithm (CSO) is an optimization algorithm which proposed in 2006. Indicated by previous studies, CSO has good performance. We proposed a method to improve CSO and presenting a modified CSO named Harmonious-CSO (HCSO). The method is changing the concept of cat alert surroundings in seeking mode of CSO. We change the formula of seeking mode and add a concept of HS algorithm. In this paper, we use Support Vector Machine (SVM) be classifier combine with feature selection to verify the performance of algorithm. For the experimental results, the HCSO algorithm has a better solution than CSO.

The LTE/LTE-A broadband cellular communication networks are expected to be quality-of-service (QoS) provisioning. The wide-spreading handheld devices with various free and easily downloadable applications make multimedia streaming services provided everywhere. Multimedia streaming data like video are compressed such that successive frames may have different sizes, and then each frame transmission is a burst with a different size. The service of delivering video is then classified as of variable bit rate (VBR). It is not easy for traffic control on VBR services. The resource utilization may be reduced if too much resource is reserved for a video stream, or video playing may be paused due to improper or less resource reservation. For these reasons, there has been some related work that makes video-on-demand (VOD) streams transmitted in constant bit rates (CBR). It will then reduce some overhead in traffic control and provide better quality of services. Besides designing suitable signaling protocols for resource reservation in LTE/LTE-A, accurate estimation of resource that should be reserved is another important topic for CBR-based transmission. In this paper, a feasible computation for minimal resource requirements is proposed for CBR multimedia streaming services in QoS enhanced LTE/LTE-A networks.

In this paper, we propose a simple but highly efficient intra skip decision algorithm to reduce the computational complexity of H.264/AVC coding. It utilizes information such as the best mode and the rate value of the RD cost function, which are all pre-calculated. These values are calculated in the corresponding macro block (MB) of the previous frame and the neighbouring MBs of the current frame in order to develop an intra skip decision rule. Our experimental results demonstrated that without the additional time-consuming computation, the proposed algorithm reduces encoding time by approximately 50% compared with the time needed for an exhaustive search and it significantly increases the time saving by 17%-30% compared with the existing algorithms. In addition, our experimental results showed that the differences in peak signal-to-noise ratio degradation are negligible and the bit rate increment is minimal.

Human Computer Interaction is becoming a major component in computer science related fields allowing humans to communicate with machines in very simple ways exploring new dimensions of research. Kinect, the 3D sensing device introduced by Microsoft which allows developers to use depth data for research. Recently, there are several mature libraries such as NITE and Kinect SDK which provide functions of Human skeleton tracking. Therefore, users may find that these applications only work with big joints of human body. When it comes to the tracking of fingers, devices such as Leap Motion will be mentioned because it provides APIs and games, which users can communicate with the computer by their fingers. Although Leap Motion Provides functions of finger tracking, the operating distance is short and users need to sit in a fixed position. Here, in this paper, authors' experimental efforts on detailed hand tracking including fingers based on Microsoft Kinect. Analyzing the depth information captured by Kinect in real time, users can apply the result in different scopes such as device controller and Virtual Instruments.

The Australian forestry industry has historically constrained the role of Information and Communication Technology (ICT) to the office environment. This negates opportunities which exist when ICT are deployed along the supply chain to provide feedback to the strategic layers for optimisations that improve efficiencies and reduce costs. The wood supply chain is largely based in the "environment": forests, roads, or mills and there is much to be gained by integrating ICT within these areas. Our experience working within the Cooperative Research Centre for Forestry (CRCF) has been that ICT systems have been developed with limited for sight around their long term sustainability: lack of consideration around the system in its context of use, placing the onus on the user to learn to adapt their work practises for system usage. This paper proposes applying design approaches found within ubiquitous computing to avoid the above shortcomings. Here the Smart Device Environment Integration (DEI) Model is applied to conceptually explore the benefits of applying a systematic approach to forestry systems design. One outcome is the design process is made easier, another is a more complete understanding of system robustness and the limitation for system acceptance from user-centric points of view.

In this paper, a novel classification scheme has been proposed for real time vehicle type classification from surveillance videos on urban roads. Three kinds of vehicle types, i.e., Small cars, large cars, and motorbikes, are classified for the later retrieval. This system is performed in various outdoor illumination and weather conditions. The average precision and recall rates of vehicle type classification are more than 93.82% and 88%, respectively. Moreover, the performance of the proposed method is up to 25 frames per seconds.

Nowadays any recognition algorithms need to work more faster and use less resources for mobile device applications. Therefore, in this paper we propose a new algorithm for the limitations in the case of traditional Mongolian script recognition. The proposed method based on a line profile in view point of the specific feature of the traditional Mongolian script. Our experimental results have shown that the proposed method is proper to printed Mongolian script.

For better efficiency of parallel and distributed computing, Apache Hadoop distributes the imported data randomly on data nodes. This mechanism provides some advantages for general data analysis. With the same concept Apache Sqoop separates each table into four parts and randomly distributes them on data nodes. However, there is still a database performance concern with this data placement mechanism. This paper proposes a Correlation Aware method on Sqoop (CA_Sqoop) to improve the data placement. By gathering related data as closer as it could be to reduce the data transformation cost on the network and improve the performance in terms of database usage. The CA_Sqoop also considers the table correlation and size for better data locality and query efficiency. Simulation results show that data locality of CA_Sqoop is two times better than that of original Apache Sqoop.
