    The evolution of instructional system design model 

    Nida Denphaisarn; Thotsapon Sortrakul (2010-12)

    The Field of instructional design and technology contain the analysis of learning and performance problems, and the design, development, implementation, evaluation and management of instructional and non instructional processes and resources are intended to improve learning and performance in a variety of settings, particularly educational institutions and the workplace. Professionals in the field of instructional design and technology often use systematic instructional design procedures and employ a variety of instructional media to accomplish...

    Search engine optimization (SEO) with Google 

    Thotsapon Sortrakul; Chinapat Eksathit (2010-12)

    At present, internet is one of the major needs for everyone. Someone needs it for finding information, social networking, etc. But many of them use it for doing commercial. Obviously, all online companies need to have their own websites or bloggers. This is increasing a number of commercial websites or bloggers available on the internet, excluding any kinds of non-commercial websites or bloggers. Imagine if you have your own website, how could you do to make many people know and be able to visit your website easily? There are many answers...

    The comparative study of Internet Infrastructure Investment between WiMAX and 3G to support incoming growth of eLearning in Thailand 

    Nakachin Wiboonprasong; Tanawat Ruangteprat (2010-12)

    This study investigates the economic feasibility study with scenario analyze the implementation of 3G Technology or WiMAX on Thailand mobile operator and Internet Service Provider. The analysis is limited to the Thailand telecommunication market. This study analyses the Thailand telecommunication market with a financial model, which shows annual cash flows, net present values (NPV), Return On Investment (ROI), payback period and scenario analyze. Nowadays, most Thailand Mobile Network Operators and Internet Service Provider are keeping their...

    Performance evaluation of L1, L2 and SL0 on compressive sensing based on stochastic estimation technique 

    Ha, Pham Hong; Vorapoj Patanavijit (2010-05)

    In this paper, we proposed 2 algorithms based on L1 and L2 norm estimator to recover the signal by using just few components. Moreover we comprehensively present the recovery algorithm based on L1, L2 and SL0 for digital signal or image under some several noise models from their incomplete observation. The proposed algorithm is used with a matrix that the number of row is much fewer than the column. The algorithm states that if signal or image is sufficient sparse, we can recover it from small number of linear measurement by solving convex p...

    A fast image recovery using compressive sensing technique with block based orthogonal matching pursuit 

    Vorapoj Patanavijit; Parichat Sermwuthisarn; Supatana Auethavekiat (2009-12)

    Traditionally, the problems of applying Orthogonal Matching Pursuit (OMP) to large images are its high computing time and its requirement for a large matrix. In this paper, we propose a fast image recovery algorithm by dividing the image into block of nxn pixels and applying OMP to each nxn block instead of the entire image. The key idea is that small matrix requires less computing time and less memory. In the experiment, the block based OMP was applied to three standard test images: Lena, Mandrill and Pirate. Compared to standard OMP, bloc...

    Video enhancement using a robust iterative SRR based on a German&McClure stochastic estimation with a general observation model 

    Vorapoj Patanavijit (2010-05)

    This paper proposes the novel robust SRR algorithm that can be effectively applied on the sequence that are corrupted by various noise models and can be applied on the real or standard sequence. First, the proposed SRR algorithm is based on the German&McClure norm that used for measuring the difference between the projected estimate of the high quality image and each low high quality image and for removing outliers in the data. Second, in order to cope with real video sequences and complex motion sequences, the proposed SRR is based on a gene...
