“…Berdasarkan pengalaman saya sebagai Guru Pendidikan Khas dan pembacaan literatur, kekurangan akses terhadap pembelajaran bahasa merupakan halangan utama dalam proses pembelajaran murid pekak (Aljedaani et al, 2021;Mohd Yasin et al, 2017;Yusoff & Mohamed, 2017). Sumber buku yang mengandungi terjemahan kod isyarat tangan untuk murid pekak agak terhad dan sukar diperoleh.…”

As a Special Education Teacher, the lack of language learning materials for deaf pupils is a challenge. Storybooks are a crucial resource for helping pupils understand the world and connect it to their real-life experiences. The ‘funds of identity’ approach has been used across a range of research studies to create storybooks for deaf pupils. To further probe its potential, an action research study involving a ‘self-reflection’ cycle process was conducted in a primary school in Sabah, Malaysia involving eight deaf students. The qualitative and narrative findings of the study indicate that storybooks based on the funds of identity have increased pupils’ interest in reading and helped them connect the story with their reality. In short, these books are important in improving the reading skills of deaf pupils. Abstrak Sebagai Guru Pendidikan Khas, kekurangan bahan pembelajaran bahasa untuk murid-murid pekak masih menjadi cabaran. Buku cerita adalah penting untuk membantu murid memahami dunia dan mengaitkannya dengan pengalaman hidup sebenar. Maka, pendekatan ‘identiti dana’ telah diadaptasikan dalam membina buku cerita yang bersesuaian dengan keperluan murid pekak. Kajian Tindakan menggunakan proses kitaran ‘refleksi-kendiri’ telah dijalankan di sebuah sekolah rendah di Sabah, Malaysia melibatkan lapan orang murid pekak. Dapatan kajian kualitatif dan naratif menunjukkan bahawa buku cerita berasaskan identiti dana telah meningkatkan minat murid dalam membaca, membantu murid membuat perkaitan dengan cerita sekali gus menambah baik penguasaan kemahiran membaca mereka.

“…Thus, Yusoff et al first proposed the use of vector magnitudes to calculate information entropy and optimize a streamline layout. (19) On the basis of this research, Guo et al calculated information entropy by utilizing the vector direction and vector magnitude comprehensively, which not only extracted feature regions but also visualized regions with abrupt changes in the vector magnitude such as shock waves. (20) Through these studies, the occlusion of a vector field became an important problem to solve.…”

Streamlines in a signal field are analyzed to describe the changes in the signal distribution of wireless sensors in this study. To generate streamlines effectively and efficiently with seed points in a vector field, we combine several algorithms to propose an adaptive method. The method is based on a quadtree data structure and information entropy. First, we improve the speed of calculating the entropy field in a vector field by an order of magnitude using a fast entropy field calculation algorithm. In the entropy gradient field, seed points are deployed along the direction of the gradient at a certain interval from the existing seed points using an entropy gradient field seeding algorithm. Then, a quadtree grid in the entropy field is obtained by dividing the field into multiple levels with high entropy using the quadtree entropy field segmentation algorithm. Upon doing this, all nodes of the grid become seed points. These algorithms significantly improve the efficiency of seed point deployment, with different densities in different locations. As a result, a better layout of streamlines in the vector field is generated.

“…Streamline generation method is the basis of realizing the flow band, flow surface and streamline basedparticle animation [15]. To a large extent, the visualization of the streamline depends on the choice of the initial point, and a reasonable initial point can retain the important characteristics of the flow field [16]. If the seed point is not properly selected, the important features of the flow field will be lost.…”

Streamline generation is an important technique for vector field visualization. Streamline uniform placement algorithm can make streamline distribution evenly and express vector information better. An effective streamline placement method should effectively express the characteristics of vector field, make the streamline distribution uniform, and allow the streamline length to be as long as possible. In this paper, a dynamic seed placement algorithm based on critical points and grid points is proposed. The algorithm firstly finds and retains the key points to ensure the key information of vector field, and then introduces uniform grids to control the streamline density of vector fieldso as to guarantee that the streamlines are evenly distributed. The experimental results show that the proposed algorithm can display the characteristic information of vector field well, makes the streamline distribution uniform, and allows the length of streamline to be long. As a result, there are almost no short streamlines. INDEX TERMS Vector field visualization, streamline uniform placement, seed point, critical point, key characteristics.
