A Portable server is the combination of popular web server software, namely Apache, MySQL, PHP and PhpMyAdmin. With a portable server, users can develop and display a developed website anywhere at any time as all web server configurations have been installed on the storage drive. Portable servers are ideal for displaying the offline version of the website anywhere when developing a website. Using a mobile server as well, users do not need hosting that requires complicated configuration and can be used to run tests before putting the website online. This study aims to obtain preliminary findings on building portable web server development kits for the teaching and learning process.

Learning Analytics for Children's Logic Development (LACLOD) is a web-based and mobile friendly learning analytic platform for assessing the logic development of children age 3 to 4 years old in TASKA PERMATA UPSI Malaysia. The platform is developed using Unity and connected through Google Analytics (GA) plugin where it tracked the user interaction for the application. LACLOD is designed only for mobile or tablet which is using Android. In this paper, the development of this learning analytic platform is presented. For evaluation of this system, observation and survey have been used, to get the feedback from 2 teachers (female) and 3 children (2 female and 1 male). Based on the evaluation, it can be seen that there are still rooms for improvement. Female children found it quit hard to understand the game but the male children looked satisfy because he knew on how to navigate the app and he actively played the app by himself. As for teachers, the acceptance to this kind of assessment is moderate, however they agree that this application can better improve the children’s learning especially in logic development.

Digital watermark technology hides copyright information in digital images, effectively protecting the copyright of digital images. At present, the color image digital watermarking algorithm still has defects such as the inability to balance robustness, invisibility and the weak anti-attack ability. Aiming at the above problems, this paper studies the digital watermarking method based on discrete wavelet transform and discrete cosine transform. Then this paper proposes a color image blind digital watermarking algorithm based on QR code. First, convert the color image from RGB space to YCbCr space, extract the Y component and perform the second-level discrete wavelet transform. secondly, block the LL2 subband and perform the discrete cosine transform. finally, use the embedding method to convert the watermark information after the Arnold transform embedded in the block. The experimental results show that the PSNR of the color image embedded with the QR code is 56.7159 without being attacked. After being attacked, its PSNR and NC values are respectively 30dB and 0.95 or more, which proves that the algorithm has good robustness and can achieve watermarking blind extraction.

Today’s Alpha generation have high competency playing digital games. This privileged ability demands creativity in terms of cognitive and higher order thinking skills when it comes to designing and developing digital games. Therefore, this study aims to delineate the process of developing a rubric to measure primary school children’s (age 7 to 12) creativity when creating games as a digital game designer. The constructs of the rubric were enthused by Torrance Creativity Theory which highlighted on originality, fluency, flexibility and elaboration that adapted to fit the concept of the game design process. The development of the rubric underwent three distinctive phases; i) library research; ii) feasibility study; and iii) expert evaluation. Cohen’s Kappa Coefficient formula was used to validate with average value κ = .81 (excellent) and the reliability was measured by Cronbach’s Alpha formula with value α = .88 (excellent). Researchers found that by adopting the concept of game-based learning specifically through game design activity, children’s creativity was significantly enhanced. The rubric of children’s creativity would be essential for sustainable performance of quality education to produce a generation of critical thinkers, problem solvers while celebrating children’s uniqueness and diversity in line to develop creative personality towards digital generation.

High efficiency video coding (HEVC) is the newest video codec to increase significantly the coding efficiency of its ancestor H.264/Advance Video Coding. However, the HEVC delivers a highly increased computation complexity. In this paper, a coding unit partitioning pattern optimization method based on particle swarm optimization (PSO) is proposed to reduce the computational complexity of hierarchical quadtree-based coding unit partitioning. The required coding unit partitioning pattern for exhaustive partitioning and the rate distortion cost are efficiently considered as the chromosome and the fitness function of the PSO, respectively. To reduce the computational time, the cellular automata-based (CA) rule based time limit is used in order to find out the best possible modes of operation. Compared to the current state of the art algorithms, this scheme is computationally simple and achieves superior reconstructed video quality (12% increase in PSNR compared to existing methods) at less computational complexity (overall delay by 40%).

In this work a new Bangla speech corpus along with proper transcriptions has been developed; also various acoustic feature extraction methods have been investigated using Long Short-Term Memory(LSTM) neural network to find their effective integration into a state-of-the-art Bangla speech recognition system. The acoustic features are usually a sequence of representative vectors that are extracted from speech signals and the classes are either words or sub word units such as phonemes. The most commonly used feature extraction method, known as linear predictive coding (LPC), has been used first in this work. Then the other two popular methods, namely, the Mel frequency cepstral coefficients (MFCC) and perceptual linear prediction (PLP) have also been applied. These methods are based on the models of the human auditory system. A detailed review of the implementation of these methods have been described first. Then the steps of the implementation have been elaborated for the development of an automatic speech recognition system (ASR) for Bangla speech.
