Commercial weather stations can effectively collect weather data for a specified area. However, their ground sensors limit the amount of data that can be logged, thus failing to collect precise meteorological data in a local area such as a micro-scale region. This happens because weather conditions at a micro-scale region can vary greatly even with small altitude changes. For now, drone operators must check the local weather conditions to ensure a safe and successful flight. This task is often a part of pre-flight preparations. Since flight conditions (and most important flight safety) are greatly affected by weather, drone operators need a more accurate localized weather map reading for the flight area. In this paper, we present the Arduino Sensor Integrated Drone (ASID) with a built-in meteorological station that logs the weather conditions in the vertical area where the drone will be deployed. ASID is an autonomous drone-based system that monitors weather conditions for pre-flight preparation. The operation of the ASID system is based on the Arduino microcontroller running automatic flight profiles to record meteorological data such as temperature, barometric pressure, humidity, etc. The Arduino microcontroller also takes photos of the horizon for an objective assessment of the visibility, the base, and the number of clouds., Comment: 12 pages, 8 figures

In a mobile learning environment, students can learn via mobile devices without being limited by time and space. Therefore, it is vital to develop tools to assist students to learn and assess their knowledge in such environments. This paper presents a tool/application for formative self-assessment. The tool supports the selection of questions based on user-defined criteria concerning (1) the difficulty level; (2) the associated concepts; and (3) the purposes of the test taker. The main purpose of the presented tool is to better support the learning aims of the participants and to increase their engagement in the learning process. The focus of this study is to evaluate the tool using quizzes in Microeconomics to realize its potential in this specific domain. Teachers and students were involved in the experiments conducted. The experiments demonstrated that the presented tool is usable; it motivates the students and improves their understanding, Comment: 10 pages, 3 images
