Method for Orthogonal Edge Routing of Directed Layered Graphs with Edge Crossings Reduction

This paper presents a method for automated orthogonal edge routing of directed layered graphs using the described edge crossings reduction heuristic algorithm. The method assumes the nodes are pre-arranged on a rectangular grid composed of layers across the flow direction and lanes along the flow direction. Both layers and lanes are separated by rectangular areas defined as pipes. Each pipe has associated segment tracks. The edges are represented as orthogonal polylines consisting of line segments and routed along the shortest paths. Each segment is assigned to a pipe and to a segment track in it. The edge crossings reduction uses an iterative algorithm to resolve crossings between segments. Conflicting segments are reassigned to adjacent segment tracks, either by swapping with adjacent segments, or by inserting new tracks and calculating the shortest paths of edges. The algorithm proved to be efficient and was implemented in an interactive graph design tool.

Perancangan Media Pembelajaran Tematik Sekolah Dasar Berbasis Serious Game

Pembelajaran tematik merupakan pembelajaran terpadu yang menggunakan tema sebagai pokok pikiran atau gagasan pokok pembicaraan dengan mengaitkan beberapa mata pelajaran, sehingga dapat memberikan pengalaman bermakna kepada siswa. Transfer pembelajaran berbasis tematik ke siswa Sekolah Dasar tidak mengalami kesulitan bagi guru jika dilakukan secara langsung di sekolah. Akan tetapi, pandemi covid-19 pada saat ini menyebabkan digunakannya media pembelajaran online sehingga guru-guru mengalami kesulitan. Kesulitan penyampaian materi tersebut juga dirasakan orang tua yang juga berusaha memberikan pembelajaran berbasis tematik di rumah berdasarkan buku yang diperoleh dari sekolah. Penelitian ini merancang framework pembelajaran berbasis serious game berdasarkan buku tematik Sekolah Dasar dengan tujuan dapat mempermudah guru dalam melakukan pembelajaran jarak jauh serta mempermudah orang tua dalam menyampaikan materi yang terdapat di dalam buku tematik tingkat Sekolah Dasar. Hasil penelitian menunjukkan bahwa komponen utama dalam perancangan serious game untuk memenuhi komponen pedagogi dan fun adalah game component, graph design, database design dan fitur design, di mana konsep immersifitas merupakan hal pokok sebagai upaya yang dapat membuat pemain masuk ke dalam suasana permainan dan mendapatkan pengalaman lebih dari permainan tersebut.

A high-precision, template-assisted, anisotropic wet etching method for fabricating perovskite microstructure arrays

A template-assisted wet etching method for the preparation of perovskite micro-structure array is proposed. This method has a superiority of flexible graph design, controllable size and high precision.

Graph Composer: music composition from graph design

The Graph Composer is an app that allows the user to compose music through the design of a graph. You can create or modify an existing graph, listen and modify the composition in real time. Insert new nodes and connect them, change the corresponding note by clicking over the node and selecting a new one from the scale, define it’s duration over time and select a decoration to change the sound sequence.
