The fusion of infrared images and visible images can combine complementary information in an image, so we can better describe a scene, and it is helpful for some tasks such as target detection, target localization and environment recognition. In this paper, we use the Second Generation Curvelet Transform (SGCT) to decompose infrared images and grayscale visible images to propose a new image fusion algorithm. This algorithm uses a multi-resolution decomposition of different tools and different fusion rules implementation. The simulation results show that, compared with existing algorithms, this algorithm have improved to some extent in the evaluation of fused images

In this paper we present an improved lattice Boltzmann model for compressible Navier–Stokes system with high Mach number.The model is composed of three components: (i) the discrete-velocity-model by M. Watari and M. Tsutahara [Phys. Rev. E 67(2003) 036306], (ii) a modified Lax–Wendroff finite difference scheme where reasonable dissipation and dispersion are naturallyincluded, (iii) artificial viscosity. The improved model is convenient to compromise thehigh accuracy and stability. The includeddispersion term can effectively reduce the numerical oscillation at discontinuity. The added artificial viscosity helps the schemeto satisfy the von Neumann stability condition. Shock tubes and shock reflections are used to validate the new scheme. In ournumerical tests the Mach numbers are successfully increased up to 20 or higher. The flexibility of the new model makes it suitablefor tracking shock waveswith high accuracy and for investigating nonlinear nonequilibrium complex systems

Content adaptation is a potential solution for tailoring multimedia web content according to the users’ preferences and heterogeneous devices’ constraints. Content adaptation can be done as third party service over the Internet. Users may pay for the service thus demand quality. The quality should include the human psychological factors. One of these factors is the maximum time a user can wait for the output to be displayed. Thus, response time is one of the qualities of service (QoS) to be considered in assessing the deliverability of content adaptation services. However, the advertised response time may not be deliverable accordingly during the actual service execution due to heavy load. Practically, the service provider should able to determine a current deliverable response time before the service level agreement (SLA) is settled with the users. In this paper, we propose a strategy for service providers to evaluate incoming requests and capable of offering the new response time. The proposed strategy takes into account the current server load and enables a mechanism for the user to evaluate whether the new response time can be accepted or not. We analyzed the performance of the proposed strategy in terms of SLA settlement under various conditions. The results indicate that the proposed strategy performs well.

The recent progress in the digital multimedia technologies has offered many facilities in the transmission, reproduction and manipulation of data. However, this advance has brought the problem such as copyright protection for content providers. Watermarking is one of the proposed solutions for copyright protection of multimedia. Most of the content provider use Photoshop to create a watermark photo, but Photoshop involve many procedures to complete a watermarked image. In addition, watermark image using Photoshop easily destroy by attacker where attacker can modifies the image to remove the watermark from the image. Hence, it has become a tough task to protect copyright of an individual’s creation. Thus, i-Mark is developed to solve the problem to protect the watermarked image. An invisible watermark embeds an imperceptible signal into data such as image,which indicates whether or not the content is copyrighted. By using i-Mark, invisible watermarking was provided where steganography method was implemented for users to encrypt message into an image. Hence, the image is protected from been easily modifies or copy by others. Meanwhile, i-Mark allow user to store their invisible watermarked image in database and can be view later. In addition, i-Mark also can made a visible watermark where user can adding text on the cover of image more convenient than Photoshop. In conclusion, i-Mark provides users to watermark their image either visible watermark or invisible watermark. Hence, throughout the project, user may use the system user friendly compare to Photoshop.

Teaching performance evaluation process in higher learning institutions (HLI) is of the most importance in building a higher education policy which purposes for teaching improvement and administrative decision making. Several issues have been raised such as 1) instrument characteristic used to detect values is not sufficient to handle subjective evaluation criteria’s and, 2) the most techniques used in handling survey data is statistical method. In conventional practice, ordinal Likert scales used for marking schema and statistical techniques are implemented for analyzing the data. In order to manage the issues, this research presents a multi-criteria decision making methodology, called analytic hierarchical process (AHP) to evaluate HLI instructors teaching performance. As a well known decision making approach, AHP can systematically cope with highly subjective problems in social system. An AHP implementation framework for teaching performance evaluation will use the possible internal factors; preparation, organization, delivery and effectiveness that are evaluated as teaching evaluation weight. The future work is also suggested, this evaluation system should be implemented in real time situations. It becomes the best platform to evaluate teaching performance and categorize instructors into appropriate bands.
