Students’ Achievement In Developing Instructional Material Of Junior High School Mathematics In English Through Implementation Of Peer Assesment In Cooperative Setting

This research proposes that to study students’ achievement in developing the instructional material of Junior High School Mathematics in English through implementation of peer assessment in cooperative setting. The subject of this study are fifth semester students of Study Program of Mathematics Education, Malang State University, offering AY 2010/2011. Descriptive study is implemented in this study. The researcher analizes syllaby, lesson plan, worksheet, media, assessment, and scenario that developing by students for teaching mathematics in English. This research concludes that students’ achievement in developing instructional material of junior high school mathematics in English through implementation of peer assessment in cooperative setting is good.This research also found that students work cooperatively and appreciate each other during the teaching learning process in coooperative setting. Key words: instructional material, teaching mathematics in English, peer assesment, cooperativ

Fault Tolerant Air Bubble Sensor using Triple Modular Redundancy Method

Detection of air bubbles in the blood is important for various medical treatments that use Extracorporeal Blood Circuits (ECBC), such as hemodialysis, hemofiltration and cardio-pulmonary bypass. Therefore a reliable air bubble detector is needed. In this study designed a fault tolerant air bubble detector. Triple Modular Redundancy (TMR) method is used on the sensor section. A voter circuit of the TMR will choose one of three sensor output to be processed further. Application of TMR will prevent errors in the detection of air bubbles, especially if the sensor fails to work

The GeV Excess Shining Through: Background Systematics for the Inner Galaxy Analysis

Recently, a spatially extended excess of gamma rays collected by the Fermi-LAT from the inner region of the Milky Way has been detected by different groups and with increasingly sophisticated techniques. Yet, any final conclusion about the morphology and spectral properties of such an extended diffuse emission are subject to a number of potentially critical uncertainties, related to the high density of cosmic rays, gas, magnetic fields and abundance of point sources. We will present a thorough study of the systematic uncertainties related to the modelling of diffuse background and to the propagation of cosmic rays in the inner part of our Galaxy. We will test a large set of models for the Galactic diffuse emission, generated by varying the propagation parameters within extreme conditions. By using those models in the analysis of Fermi-LAT data as Galactic foreground, we will show that the gamma-ray excess survives and we will quantify the uncertainties affecting the excess morphology and energy spectrum.Comment: 2014 Fermi Symposium proceedings - eConf C14102.1 7 pages, 4 figure
