Quantized bound states at a vortex core are discretized in YNi2B2C. By using scanning tunneling spectroscopy with an unprecedented 0.1 nm spatial resolution, we find and identify the localized spectral structure, where in addition to the first main peak with a positive low energy, a second subpeak coming from the fourfold symmetric gap structure is seen inside the energy gap. Those spectral features are understood by solving the Bogoliubov-de Gennes equation for a fully three-dimensional gap structure. A particle-hole asymmetric spectrum at the core site and quantum oscillation in the spectra are clearly observed.

An experimental work to investigate the swirl spray characteristics that emanates from hollow–cone and solid–cone spray simplex atomizers is presented. Main objective of the research is to investigate the spray characteristics, i.e. spray breakup length, discharge coefficient and spray cone angle at different nozzle orifice diameter and injection pressure. Discharge coefficient is almost uninfluenced by the operating Reynolds number. This test also reveals that both breakup length and spray cone angle increases as orifice diameter is increased. Higher injection pressure leads to shorter breakup length and wider spray cone angle.

This innovative project aims to monitor water quality in the area of continental, the coast and the lake using mobile buoy remotely controlled by a computer which sends a series of commands to Intel Atom N2600 Board and microcontrollers over Global System for Mobile Communication (GSM). The user enters the desired coordinate to Graphical User Interface (GUI) monitoring software from a remote computer. The buoy moves to the desired coordinate that relies on Global Positioning System (GPS) current reading. Sets of data of PH, Oxidation Reduction Potential (ORP) and temperature sensors reading is taken from sensors attached at the buoy. The data and the coordinate of the buoy location is uploaded and mapped via Google Map. The Google Map is integrated into the GUI to display the buoy position. The user can freely monitor real-time water quality information and the buoy will go to any location coordinated by the user's command.
