Use of a weighted matching algorithm to sequence clusters in spatial join processing

One of the most expensive operations in a spatial database is spatial join processing. This study focuses on how to improve the performance of such processing. The main objective is to reduce the Input/Output (I/O) cost of the spatial join process by using a technique called cluster-scheduling. Generally, the spatial join is processed in two steps, namely filtering and refinement. The cluster-scheduling technique is performed after the filtering step and before the refinement step and is part of the housekeeping phase. The key point of this technique is to realise order wherein two consecutive clusters in the sequence have maximal overlapping objects. However, finding the maximal overlapping order has been shown to be Nondeterministic Polynomial-time (NP)-complete. This study proposes an algorithm to provide approximate maximal overlapping (AMO) order in a Cluster Overlapping (CO) graph. The study proposes the use of an efficient maximum weighted matching algorithm to solve the problem of finding AMO order. As a result, the I/O cost in spatial join processing can be minimised

The implementation of video clip in teaching English vocabulary

This study aimed at explaining the implementation of video clip to teach English vocabulary for Elementary students. Besides, this study also focused to investigate the barrier of implementation of video clip to each vocabulary. This study applied descriptive qualitative method to display the result of the research. The collection of data was conducted with two instruments: written exercise and interview. The written test consists of 20 questions that must be answered by students at the time. Furthermore, the written test was used to investigate about how the progress was made by students using this kind of method and how good students catch information from the media. Meanwhile, interview was used to gather data from the teacher of the students. There was only one English teacher that was interviewed to collect the necessarily data. There were 26 populations in a class at SD Al- Irsyad Al- Islamiyah Semarang. Based on the result of the data collection, it turned out that 66% out of 26 students could successfully implement this method in learning. In the other hand, 34% out of 26 students did not show significant progress in learning using this method. The barrier found out from the implementation of this method was the lack of Students awareness to catch the information from the video rather than watch the pictures displayed

Pengaruh Model Pembelajaran Tematik dan Gaya Belajar Terhadap Hasil Belajar Siswa Kelas II

Thematic learning model is a learning model that students pay attention to SD/MI that frame of mind is still intact, and the understanding of the concept are through the real world and based to the students lives. In this study the researcher focus to the model of learning interaction and learning styles on learning outcomes. The researcher used experimental study. The study population was all students in second student grade. The sample amounted to 90 students from both MI, it means that the researcher used purposive sampling, where all students are included on certain conditions. The collected data were statistically processed using the techniques of inferential analysis of variance (Anova) two-factor 2 x 2. The results of this study, (1) there are differences in learning outcomes between students who use thematic learning and conventional learning, (2) there are differences in student learning outcomes that have a stylish visual, auditory and kinesthetic, and (3) there is no interaction between learning models and styles learning on learning outcomes. Descriptive Statistics show that the application of thematic learning (mean 80.49) and the conventional learning (mean 77.87). And mean learning outcomes based on visual learning style is 84.81, auditory learning style is 73.48, and kinesthetic learning styles is 75.09. Based on the research findings, it is recommended to the elementary school teachers to apply the thematic instructional strategies in the instruction to improve student learning achievement. The characteristic of thematic strategy can empower student to learn optimally and support the student learning achievement.Keywords: Thematic Learning Model, Learning Styles and Student Learning Outcome

Aerosol Particle Bounding in Cascade Impactors

Particle deposition characteristics were observed from the aerosol sampling results of a UNICO cascade impactor. A simple model of particle motion combined with Hiemenz flow of stagnation flow on a flat plate were developed and discussed. Both results and analysis were compared to recent models on particle bouncing errors or secondary deposition which included vortices formation around the edge of the slot, back spin (Magnus effect), and hydrodynamic conditions of the particles. The analysis was limited to a laminar inviscid and incompressible case. The main obstacle in the observation was the fact that impactor nozzles were unsymmetrical to a considerable degree, thereby deviating particle trajectory significantly from the predicted situation
