Shape And Size

Voids that are formed by gas injection in a packed bed play an important role in metallurgical and chemical furnaces. Herein, two-phase gas–solid flow in a two-dimensional packed bed during blast injection was simulated numerically. The results indicate that the void stability was dynamic, and the void shape and size fluctuated within a certain range. To determine the void morphology quantitatively, a probabilistic method was proposed. By statistically analyzing the white probability of each pixel in binary images at multiple times, the void boundaries that correspond to different probability ranges were obtained. The boundary that was most appropriate with the simulation result was selected and defined as the well-matched void boundary. Based on this method, the morphologies of voids that formed at different gas velocities were simulated and compared. The method can help us to express the morphological characteristics of the dynamically stable voids in a numerical simulation.

Ethnomathematics is the study of the relationship between mathematics and culture that found in society. This research was conducted at the GESIBU Blambangan Banyuwangi gate. The purpose of this study was to describe ethnomatematics form at the Blambangan GESIBU Gate and arrange it into the research product in the form of ethnomatematic-based student worksheets (LKS). This research is a qualitative research with descriptive data analysis. There are three data collecting technique being used, those are observation, interview, and documentation The subject of this research were four people, namely cultural observers, archaeologists, builders, and carvers. The results showed that there were an ethnomatematics in the arrangement of shapes and sizes for each component of the gate from its roof, body, foot and the carving. The shape and size from each gate component contain ethnomatatics, such as two-dimensional figure, solid figure/geometry, geometric transformation (reflection, dilation, and rotation), and arithmetic sequence patterns
