Experimental data of several forms have been obtained which constitute interlocking concordant evidence of amplification in self-trapped plasma channels on several transitions of the Xe(L) hollow atom spectrum at wavelengths in the range λ ∼ 2.71-2.93 Å. Specifically, they are (α) strongly enhanced spectra arising from Xe31+, Xe32+, Xe34+, Xe35+, Xe36+, and Xe37+ ions recorded from the channel in the forward (axial) direction, (β) the measurement of a corresponding spectral narrowing on the directionally enhanced lines emitted from the channel, (γ) evidence for saturation of three of these transition arrays (Xe34+, Xe35+, Xe36+) given by the simultaneous quenching (spectral hole-burning) of the corresponding spontaneous emission from them in transversely recorded spectra only when amplifying channels are present.

Pixel-to-point Transfer: a Process for Integrating Individual GaN-based Light-emitting Devices in o Heterogeneous Microsystems

A novel ultra-low-thermal-budget pixel-to-point transfer process based on the excimer laser lift-off and Pd-In transient-liquid-phase bonding scheme was developed for flexible and precise placement of single pixels of GaN-based light-emitting diodes (LED) on target substrates. The transfer was accomplished by (1) temporarily bonding the light-emitting diode (LED) pixel to a specially designed pick-up rod with sapphire substrates facing up using Super Glue., (2) removing the sapphire substrates using laser lift-off, and (3) registering and permanently bonding the LED pixel to the designated area in the target substrates using Pd-In transient-liquid-phase bonding. An oxygen plasma was employed to remove the Super Glue® residue before further microfabrication and system integration was performed. The capability of this technique was demonstrated in the integration of GaN-based LED pixels with pre-fabricated PIN photodiode chips and thin-film bandedge filters, which formed the non-disposable subsystems of a fluorescence-based lab-on-a-chip system. The performance of these integrated LED pixels and the integrated microsystems has been assessed by evaluating the fluorescence intensity as a function of equivalent fluorescein dye concentration using disposable polydimenthyl siloxane(PDMS) microfluidic channels. GaN LEDs with peak emission at 463 nm were used to excite 515nm fluorescence from FluoSpheres® carboxylate-modified fluorescent microspheres (40nm in diamters).

X-ray amplification in self-trapped plasma channels from xenon hollow atom states at 2.71 2.93 angstroms was investigated. Xe(L) spectrum was recorded with an estimated spectral resolution of ∼4 eV in the forward (axial) direction from the plasma channel. The film exposure indicates that a single amplified Xe32+pulse was recorded along with ∼1200 pulses of isotropically radiated spontaneous emission. The width (FWHM) of the narrow Xe32+feature was delta32≅4.0 eV.

This paper introduces a multi-paradigm dynamic system simulator based on discrete time and discrete event formalism for simulating a supply chain as a complex adaptive system. Little is known about why such a diversity of supply chain structures exist. Simulating dynamic supply chain networks over extended periods using the multi-paradigm dynamic system simulator allows us to observe the emergence of different structures. The simulator is implemented using a software agent technology, where individual agents represent firms in a supply chain network. In this paper, we present an example scenario run on the simulator and the preliminary results that have been observed. This multi-paradigm tool provides a valuable investigation instrument for real life supply chain problems.

IEEE Pacific Rim Conference on Communications, computers and Signal Processing

In IEEE 802.11 wireless local area networks (WLANs); the binary exponential backoff (BEB) algorithm is used in the medium access control (MAC) protocol to resolve contortion problems. Unfortunately, BEB has been shown to be highly short-term unfair. In this paper, we propose a probabilistic contention window control mechanism to improve the fairness of the backoff procedure and we evaluate its performance on real-time applications such as voice over IP and video conferencing. Simulation results reveal improvements in fairness and throughput, without detriment to delay and jitter.

On Classifying Daylight for Design

In this paper, we present LiQuID, a tool for clustering lighting simulation data. Photographs are useful vehicles for both describing and making assessments of architectural lighting systems. A significant barrier to using photographs during the design process relates to the sheer volume of renderings that needs to be analyzed. Although there have been efforts to produce novel visualization systems to manage large sets of photographs, this research aims to reduce the complexity by classifying data into representative prototypes. A hypothetical case study is discussed.

We propose a method for process monitoring of a semiconductor manufacturing process. Independent component analysis (ICA) is applied to characterize E-test parameter data. We calculate angular confidence intervals for the model, eliminate marginally significant components and implement control charts for significant components of interest. Alarms are generated off of deviations in the charted components. Alarms are easily used in process diagnosis based on the interpretation of the independent components.
