To learn while being entertained is always an effective means in education. With the advance in technologies, in particular graphics, multimedia, and virtual reality te- nologies, this has evolved into the specific area of “Edutainment”. The second int- national conference on edutainment, Edutainment 2007, aimed to provide a forum for practitioners and researchers in the field to share their experiences...
In this paper, an axial-radial flux compound-structure permanent-magnet synchronous machine (CSPMSM) which consists of one axial-flux PMSM and one radial-flux PMSM is investigated. The purpose of this kind of machine is to keep the internal combustion engine (ICE) operating at maximum efficiency by harmonizing its two machines during all driving cycles in hybrid electric vehicle (HEV), and therewith...
This paper presents an acoustic emission (AE) monitoring method. When a partial discharge occurs, there is an instantaneous release of energy, some of which is emitted as acoustic energy. The pollution severities of insulators in-service can be monitored and accordingly threaten to the insulation of power grid is evaluated by detecting the sound signals. To prove this AE monitoring method, artificial...
In this paper, metallodielectric IR FSS filters were synthesized using fractal and GA techniques with fabrication constraints. Measured results show excellent agreement with PMM simulation. The synthesis of DFSS for near-IR filter applications was performed using a GA. The advantages of DFSS include low loss at visible wavelengths and polarization independent filter responses. Designs for low loss...
In this paper, micron-scale metallodielectric and all-dielectric frequency selective surfaces (FSS) are synthesized with a liquid crystal (LC) superstate to exhibit broadband tunable filter characteristics at mid-infrared (IR) wavelengths. The low loss and birefringence properties of LC span the visible to far-IR spectrum, providing potential for the development of a new class of infrared/optical...
A new design concept was presented for reconfigurable FSS that uses silicon as switches. Signals at frequencies around/above 100 GHz (D-band) are of interest for several applications including atmospheric sensing, wideband communications, automotive radar and test instrumentation. This paper presented two RFSS examples, one design with metallic patches and one with all dielectric materials at a target...
Experimental processes to collect and process proteomics data are increasingly complex, while the computational methods to assess the quality and significance of these data remain unsophisticated. These challenges have led to many biological oversights and computational misconceptions. We developed a complete empirical Bayes model to analyze multi-protein complex (MPC) proteomics data derived from...
In this paper, a new delay-locked loop (DLL) architecture is proposed to effectively improve the DLL jitter performance. A novel realignment duty cycle corrector (RDCC) is proposed for the DLL. The RDCC circuit can make the output waveform of the DLL maintain a 50% duty cycle in a lock mode. The RDCC circuit has advantages of low power consumption, small chip area and high operating frequency. The...
Per-flow traffic measurement is critical for usage accounting, traffic engineering, and anomaly detection. Previous methodologies are either based on random sampling (e.g., Cisco's NetFlow), which is inaccurate, or only account for the "elephants". We introduce a novel technique for measuring per-flow traffic approximately, for all flows regardless of their sizes, at very high-speed (say,...
The HAMR head-disc interface is the subject of intense research due to its potential to extend the areal density of magnetic recording to the Tb/in2 and above range. We have studied possible material constituents of this interface to determine their robustness for this technology. Of specific interest are the effects of repeated high thermal excursions on these materials. Furthermore, it is expected...
