2009 9th IEEE Conference on Nanotechnology (IEEE-NANO), 2009
The ability to tailor the properties of semiconductor nanocrystals through creating core/shell heterostructures is the cornerstone for their diverse application in nanotechnology. The band-offsets between the heterostructure components are determining parameters for their optoelectronic properties, dictating for example the degree of charge-carrier separation and localization. So far, however, direct measurement of these factors in colloidal nanocrystals were not reported and ...

This summary discusses time-domain simulation results of two thyristor based static transfer switch (STS) systems. The objectives are: (1) to provide guidelines for digital simulation of STS systems; and (2) to provide a basis for accuracy evaluation of simulation studies used for STS performance analysis. Each system is composed of: (1) a supply system; (2) a STS; and (3) a sensitive load. The two systems are referred to as STS-1 and STS-2. Simulation performances of the two systems are obtained based on the use of PSCAD/EMTDC software package. Simulation results corresponding to STS-2 are also compared with the measurement results.
The ability to tailor the properties of semiconductor nanocrystals through creating core/shell heterostructures is the cornerstone for their diverse application in nanotechnology. The band-offsets between the heterostructure components are determining parameters for their optoelectronic properties, dictating for example the degree of charge-carrier separation and localization. So far, however, direct measurement of these factors in colloidal nanocrystals were not reported and only indirect information could be derived from optical measurements. Here we demonstrate that scanning tunneling spectroscopy (STS) along with theoretical modeling can be used to determine band-offsets in such nanostructures. Applying this approach to CdSe/CdS quantum-dot/nanorod core/shell nanocrystals portrays its type-I band structure where both the hole and electron ground-state are localized in the CdSe core, in contrast to previous reports which predicted electron delocalization. We applied our approach also for ZnSe/CdS nanocrystals, portraying their type-II band alignment, leading to electron-hole separation.
Increasingly, security requirements are being viewed as a social construct derived from the culture and society within which the requirement is said to exist. A socio-technical system can be modelled as a series of inter-related, and interacting patterns of behaviour. Within a socio-technical system a security requirements can be derived from the analysis and interaction of the pattern. To capture and understand these requirements/patterns we need to make use of a formal reasoning system that supports a rigorous deductive process. In this paper we will develop a formal model of a socio -- technical systems pattern using a Kripke Semantic model. Then, via the application of Kripke Semantics to the modelling of responsibilities and how they are created/fulfilled within a socio -- context, we will derive a set of security requirements/patterns.
Many distributed multimedia applications involve data delivery from a source to multiple destinations, the participating nodes forming a multicast group. In the naive solution, separate connections can be established from each source to other group members. However a tree can be established for each source with the participants as the leaf nodes or just have one tree spanning all the participants. In this paper, we introduce a data forwarding model to support such shared multicast trees over the ATM networks called CRAM (cell re-labeling at merge-points for ATM multicast). Our work allows VC merging in the MPLS architecture and supports recently proposed wide area multicast protocols (like CBT and PIM) in ATM networks.
The motion of a particle in 6-dimensional phase space in the presence of linear coupling can be written as the sum of 3 normal modes. A cubic equation is found for the tune of the normal modes, which allows the normal mode tunes to be computed from the 6/spl times/6 one turn transfer matrix. This result is similar to the quadratic equation found for the normal mode tunes for the motion of a particle in 4-dimensional phase space. These results are useful in tracking programs where the one turn transfer matrix can be computed by multiplying the transfer matrices of each element of the lattice. The tunes of the 3 normal modes for motion in 6-dimensional phase space can then be found by solving the cubic equation. Explicit solutions of the cubic equation for the tune are given in terms of the elements of the 6/spl times/6 one turn transfer matrix.
The topic of Human-Adaptive Socio-Technical Systems - requiring human-centered concepts, languages and methods to specify system behavior and to model human behavior - is increasingly important as these systems become complexly entangled in everyday lives and contexts. However, the extent to which we achieve `good' systems is very much shaped by what gets specified and modelled about the human in the system. Using the case of older people and care, I will draw attention to the gaps between modelling of behaviours for building systems and negotiating the lived realities of those behaviours, pointing to tensions around whose voice(s) count, what conceptualisations of `old' and `care' dominate, how competing values are negotiated or not, and who defines what adaptations are appropriate. At an application level I want to argue for enabling older people to become active co-contributors to care networks rather than passive recipients of care, and designing for living not aging. More generally though I want to argue for the critical importance of growing our own social and emotional competencies to more sensitively engage with the complexities Human-Adaptive Socio-Technical Systems and embrace an explicit concern for the values we are modelling into our systems.
This paper presents a least square quadratic phase interpolation algorithm for sinusoidal model based music synthesis. This algorithm uses two additions with one parameter per data frame to generate the phase samples of a component sinewave. Compared with the cubic phase interpolation algorithm proposed by McAulay and Quatieri (1986), the proposed algorithm is more efficient in terms of computational complexity and parameter storage. In the meantime, it also produces smoother frequency tracks (that is, with less spurious oscillations). Unlike the existing quadratic phase interpolation algorithm, where the phase measurements are ignored ("magnitude-only"), the proposed algorithm interpolates phase in a least square sense from both the phase and the frequency measurements at data frame boundaries. Thus the resulting phase samples are approximately "locked" to the measured ones. Informal listening tests on various musical instrument tones indicate that the proposed algorithm clearly outperforms the magnitude-only synthesis approach and is qualitatively comparable to the cubic one.
3D continuous emission and spiral transmission (CEST) scanning provides a high-throughput whole-body PET study using two dedicated detectors for 3D emission and single transmission with continuous bed movement. Since post- injection single transmission data contains emission contamination (EC) and transmission scatter components (TSC), the transmission detector was designed to have a short axial extent with a highly collimated <sup>137</sup>Cs point source, and be implemented using a realtime EC correction method. However, transmission images can be still affected by residual EC and TSC, depending on patient size and dose injected. This results in slight variations in attenuation coefficients, depending on the patient's axial position. In this study, we developed a new soft-tissue segmentation (STS) method based on histogram scaling at each axial position of the spiral transmission. Peaks, corresponding to soft-tissue in a histogram of attenuation coefficients, were found at each axial position and the transmission image was scaled using the ratio of soft-tissue histogram peaks to the theoretical water attenuation coefficient. In scaled transmission images, the pixel values near the soft- tissue peak were replaced with the theoretical water attenuation coefficient. Quantitative evaluation was performed of the transmission images obtained under various acquisition conditions, both with and without the proposed STS method. Regarding final imaging performance, emission images reconstructed using both STS attenuation correction and hybrid scatter correction were evaluated. Results showed that the proposed STS method for spiral transmission scanning provided quantitative images independent of object size and containing activity concentration.
Text on documents can generally be classified into one of two categories, unconstrained and constrained, based on the spatial and contextual knowledge that is needed for comprehension. These constraints are found to be critical in text understanding. A model-based approach to reading constrained text is described. The system consists of two major components: a knowledge acquisition module and an image decoding module. Constraints on an application domain are encoded in a hierarchical stochastic model. Subparts of the hierarchy form hidden Markov models, which are used to determine decoding credibility. Verification of a terminal component of the hierarchy is performed by word recognition. Interpretation of a text block is by finding the highest credibility path in the hierarchy. The decoding process is application independent, as demonstrated in the experiments. The system has been tested on reading postal permits and other domains will be used in future tests.<<ETX>>
