Mobility Management Framework (2008)

This paper investigates mobility management strategies from the point of view of their need of signalling and processing resources on the backbone network and load on the air interface. A method is proposed to model the serving network and mobile node mobility in order to be able to compare the different types of mobility management algorithms. To obtain a good description of the network we calculate descriptive parameters from given topologies. Most mobility approaches derived from existing protocols are analyzed and their performances are numerically compared in various network and mobility scenarios. We developed a mobility management framework that is able to give general designing guidelines for the next generation mobility managements on given network, technology and mobility properties. With our model an operator can design the network and tune the parameters to obtain the optimal implementation of course revising existing systems is also possible. We present a vertical handover decision method as a special application of our model framework.
GANerated Hands for Real-time 3D Hand Tracking from Monocular RGB (2017)

We address the highly challenging problem of real-time 3D hand tracking based on a monocular RGB-only sequence. Our tracking method combines a convolutional neural network with a kinematic 3D hand model, such that it generalizes well to unseen data, is robust to occlusions and varying camera viewpoints, and leads to anatomically plausible as well as temporally smooth hand motions. For training our CNN we propose a novel approach for the synthetic generation of training data that is based on a geometrically consistent image-to-image translation network. To be more specific, we use a neural network that translates synthetic images to "real" images, such that the so-generated images follow the same statistical distribution as real-world hand images. For training this translation network we combine an adversarial loss and a cycle-consistency loss with a geometric consistency loss in order to preserve geometric properties (such as hand pose) during translation. We demonstrate that our hand tracking system outperforms the current state-of-the-art on challenging RGB-only footage.
An improved RGB-D SLAM algorithm based on Kinect sensor (2015)

This paper presents an improved frontend algorithm of RGB-D SLAM, that is, Extend-RGBD-ICP algorithm. After introducing the existing frontend algorithm and analyzing its drawbacks, we present three improvement aspects: point cloud data down-sampling, matching points' selection and elimination of cumulative error of consecutive frames splicing. From the experiments on different complexities scenarios and the evaluation on benchmark dataset, it can be seen that the Extend-RGBD-ICP algorithm can achieve both accuracy and efficiency.
Market Orientation in Australian SME’s: A Size Based Comparison (2000)

Market orientation theory highlights the role of information acquisition, dissemination and utilisation in meeting customer needs. Prior studies have examined the relationship between market orientation and performance as well as other consequences and requirements. Market orientation activities of a sample of Australian firms are examined to observe whether there are size-related differences. The consistency of market orientation between firms in different size groups and the relationship to performance differences is examined. The survey instrument is based on a conceptualisation of market orientation that includes intelligence gathering, dissemination and responsiveness. Businesses located in the Newcastle and Lower Hunter Region of Australia were surveyed, resulting in responses from 249 firms that were allocated to two size groups based on a size-based definition of small business. A positive relationship between market orientation, firm performance and esprit de corps in both the small and larger firms was found. There was no significant difference in the levels of the three individual components of market orientation between the two groups. Small and larger firms gathered intelligence, disseminated it and responded similarly. Sensitivity tests confirmed the results. Hypotheses proposing positive consequences for market oriented businesses were supported, regardless of firm size. Further analysis of the survey data will examine whether other firm demographics, such as line of business, influence market orientation and performance.
Cloning and sequencing of a cellobiohydrolase gene from Trichoderma harzianum FP108 (1999)

A cbh1 cellobiohydrolase gene was cloned and sequenced from the fungus Trichoderma harzianum FP108. The cloning was performed by PCR amplification of T. harzianum genomic DNA, using PCR primers whose sequence was based on the cbh1 gene from Trichoderma reesei. The 3' end of the gene was isolated by inverse PCR; attempts to clone regions upstream of the 5' end of the gene were unsuccessful. Sequence comparisons suggest that this gene is closely related to cbb1 genes from other Trichoderma species. In particular, all catalytically important amino acids in the protein sequence deduced from the T harzianum cbb1 gene are conserved between species.
Molecular tectonics (1995)

Abstract Tectons are defined as molecules whose interactions are dominated by specific attractive forces that induce the assembly of aggregates with controlled geometries; molecular tectonics is the art and science of supramolecular construction using tectonic subunits. Intermolecular hydrogen bonds offer a particularly effective force for promoting controlled tectonic aggregation, and tectons able to participate in extensive networks of hydrogen bonds can be constructed by the simple expedient of attaching multiple 2-pyridone subunits to carefully chosen molecular frameworks. For example, tectons that incorporate four tetrahedrally oriented 2-pyridone subunits are predisposed to generate diamondoid networks or related three-dimensional lattices. As expected, crystallization of nominally tetrahedral tectons 8, 10, and 11 produces diamondoid hydrogen-bonded networks with distances between the centers of adjoining tectons varying from approximately 12 to 20 Å. These networks define large internal volumes that are filled by a combination of independent interpenetrating diamond networks and enclathrated guests. Such networks are porous enough to permit the exchange of guests and robust enough to remain intact, even though their structural integrity is maintained only by hydrogen bonding. Three-dimensional hydrogen-bonded networks not based on diamond can be generated by the association of related tectons, including stannane 13, that incorporate features designed to make them more deformable. These observations are important because they suggest that clever application of the strategy of molecular tectonics can be used to build an unlimited range of ordered three-dimensional organic networks with some of the desirable properties of zeolites and related inorganic materials, including high structural integrity, potentially large void volumes, and adjustable microporosity.
A digital linescan camera with embedded micro-processor (2002)

EG&G Reticon has developed a next generation, digital linescan camera system with an embedded micro-processor. The on-board processor performs many functions which have traditionally been handled in the analog domain. Specifically, the problem of channel to channel balance of a multi-tap sensor is solved by feeding back digitally to the micro-processor encompassing all of the drift components in the signal chain, including the A/D converter. The digital architecture also gives the user access to camera settings for real-time performance optimization based on actual camera data. The camera's novel architecture is complemented by the inclusion of a new generation sensor developed at EG&G Reticon. The pinned photodiode detector has excellent blue light response and can read out at over 40 MHz. This paper describes the architecture of the camera and gives a brief overview of the advantages of the new sensor technology.
Chemistry of Furan Conversion into Aromatics and Olefins over HZSM-5: A Model Biomass Conversion Reaction (2011)

The conversion of furan (a model of cellulosic biomass) over HZSM-5 was investigated in a thermogravimetric analysis–mass spectrometry system, in situ Fourier transform infrared analysis, and in a continuous-flow fixed-bed reactor. Furan adsorbed as oligomers at room temperature with a 1.73 of adsorbed furan/Al ratio. These oligomers were polycyclic aromatic compounds that were converted to CO, CO2, aromatics, and olefins at temperatures from 400 to 600 °C. Aromatics (e.g., benzene, toluene, and naphthalene), oligomer isomers (e.g., benzofuran, 2,2-methylenebisfuran, and benzodioxane), and heavy oxygenates (C12+ oligomers) were identified as intermediates formed inside HZSM-5 at different reaction temperatures. During furan conversion, graphite-type coke formed on the catalyst surface, which caused the aromatics and olefins formation to deactivate within the first 30 min of time on-stream. We have measured the effects of space velocity and temperature for furan conversion to help us understand the chemistry of biomass conversion inside zeolite catalysts. The major products for furan conversion included CO, CO2, allene, C2–C6 olefins, benzene, toluene, styrene, benzofuran, indene, and naphthalene. The aromatics (benzene and toluene) and olefins (ethylene and propylene) selectivity decreased with increasing space velocity. Unsaturated hydrocarbons such as allene, cyclopentadiene, and aromatics selectivity increased with increasing space velocity. The product distribution was selective to olefins and CO at high temperatures (650 °C) but was selective to aromatics (benzene and toluene) at intermediate temperatures (450–600 °C). At low temperatures (450 °C), benzofuran and coke contributed 60% of the carbon selectivity. Several different reactions were occurring for furan conversion over zeolites. Some important reactions that we have identified in this study include Diels–Alder condensation (e.g., two furans form benzofuran and water), decarbonylation (e.g., furan forms CO and allene), oligomerization (allene forms olefins and aromatics plus hydrogen), and alkylation (e.g., furan plus olefins). The product distribution was far from thermodynamic equilibrium.
Thermomechanical Behavior of Wheat Gluten Films: Effect of Sucrose, Glycerin, and Sorbitol (1995)

Glass transition temperature (Tg) and mechanical and water vapor barrier properties of wheat gluten films containing glycerin, sucrose, glycerin-sucrose, and glycerin-sorbitol were studied. Glycerin and sucrose were immiscible; the wheat gluten film containing both solutes showed two separate thermal transitions (-58°C and -5°C, respectively). The low temperature (low-T) transition (-58°C) was due to a glycerin-rich region. The low-T tan δ peak height influenced the tensile strength and elongation linearly and the water vapor permeability (WVP) curvilinearly. However, the Tg failed to change with solute composition and exhibited low correlation with barrier and mechanical properties. Initial addition of glycerin increased the WVP dramatically. Sucrose decreased the WVP (only slightly), but resulted in a rigid and fragile film. The gluten-glycerin-sorbitol film at a ratio of 15:3:3 (w/w), 16.7% moisture (wb), showed a single effective Tg (-42°C) and intermediate values for tensile strength, percent elongation, and WVP, which were between those of the 15:6:0 and 15:4:2 gluten-glycerin-sucrose films.
Source-independent full-waveform inversion of seismic data (2003)

Abstract A rigorous full-waveform inversion of seismic data has been a challenging subject, partly because of the lack of precise knowledge of the source. Since currently available approaches involve some form of approximations to the source, inversion results are subject to the quality and choice of the source information used. We propose a new full-waveform inversion methodology that does not involve source spectrum information. Thus, potential inversion errors from source estimation can be eliminated. A gather of seismic traces is first Fourier transformed into the frequency domain, and a normalized wavefield is obtained for each trace in the frequency domain. Normalization is done with respect to the frequency response of a reference trace selected from the gather, so the complex-valued normalized wavefield is dimensionless. The source spectrum is eliminated during the normalization procedure. With its source spectrum eliminated, the normalized wavefield lets us construct an inversion algorithm without the source information. The inversion algorithm minimizes misfits between a measured normalized wavefield and a numerically computed normalized wavefield. The proposed approach has been demonstrated successfully using a simple 2D scalar problem.

A Self-Assembled Calix[4]arene Dimer Linked through Hydrogen-Bonded 2-Ureidopyrimidin-4(1H)-one Groups (1999)

Tightly linked! A linear array of complementary hydrogen bonds forms between two 2-ureidopyrimidin-4(1H)-one rings attached to the upper rims of facing 1,3-alternate calix[4]arenes (shown schematically). The strength of the binding (K<sub>ass</sub> >10<sup>6</sup> M<sup>-1</sup> in chloroform) and the efficiency of the self-assembly open up interesting perspectives in the design of highly ordered multicomponent cages.
Graphene Oxide Filled Nanocomposite with Novel Electrical and Dielectric Properties (2012)

Graphene oxide filled polymer nanocomposites are found to possess excellent nonlinear electrical conductivity, low conductivity at low field and a good combination of increased dielectric constant and low loss factor. Those outstanding electrical properties are achieved at filler loading of 3% and controllable by adjusting the oxidation state of graphene oxide.
Modeling Non-Functional Aspects in Service Oriented Architecture (2006)

Service oriented architecture (SOA) is an architectural style to reuse and integrate subsystems in existing systems for designing new applications. Each application is designed in an implementation independent manner using abstract concepts: network services and connections between network services. In SOA, the non-functional aspects of services and connections should be described separately from their functional aspects because different applications use services and connections in different non-functional contexts. This paper proposes a UML profile to graphically design the non-functional aspects in SOA and maintain them in an implementation independent manner. This paper presents the design of the proposed UML profile and describes how it is used in service-oriented application development

Demand-supply interaction and production planning for short-life cycle products (2005)

This graduate thesis is a study of production planning response to the erratic demand signals in short life cycle products. Governing short life cycle products have become a challenge in today's business world as their potential to generate profits to the firm has come under tight scrutiny from both strategic and tactical perspectives. In this scenario, profits generated from new products would hinge on careful execution of the production plans in response to the demand in the market. However, that execution requires detailed analysis of the demand signals, dynamic demand-sales interactions and corresponding development of production plans which minimizes costs and maximizes sales profits associated with the product. We first do an extensive literature review on the various treatments of short lifecycle products. We come to realize that the research done in this area is very limited and is in its infancy. We focus our attention towards the development of production strategies for short lifecycle products. We develop generalized mathematical cost model to better explain the demand-supply interaction that occurs in short life cycle products. (Abstract shortened by UMI.)
Quantum computation, quantum state engineering, and quantum phase transitions driven by dissipation (2008)

We investigate the computational power of creating steady-states of quantum dissipative systems whose evolution is governed by time-independent and local couplings to a memoryless environment. We show that such a model allows for efficient universal quantum computation with the result of the computation encoded in the steady state. Due to the purely dissipative nature of the process, this way of doing quantum computation exhibits some inherent robustness and defies some of the DiVincenzo criteria for quantum computation. We show that there is a natural class of problems that can be solved with such a model - the preparation of ground states of frustration free quantum Hamiltonians. This allows for robust and efficient creation of exotic states that exhibit features like topological quantum order and the creation of PEPS and it proves the existence of novel dissipative phase transitions. In particular the latter can in principle be verified experimentally with present day technology such as with optical lattices.
Silicon dioxide passivation of InP/InGaAs metal-semiconductor-metal photodetectors (1996)

We report on passivation and antireflection coating of InP/InGaAs metal-semiconductor-metal photodetectors by low-temperature deposited silicon dioxide. The passivating performance of silicon dioxide films applied by nonreactive radio frequency magnetron sputtering and remote plasma enhanced chemical vapor deposition are comparatively investigated. Different wet chemical treatments of the InP surface prior to deposition including sulfur passivation are performed and their influences on the device performance are presented. Under optimized deposition conditions and pretreatments, both processes result in a stable and reproducible surface passivation as reflected by a drastic reduction of excessive leakage currents and photocurrent gain. The improvement of the device characteristics due to the silicon dioxide coating is attributed to a substantial lowering of the density of interface states at the insulator-InP interface as compared to nonpassivated devices.
Hyperventilation (2010)

Abstract Hyperventilation (or hypocapnia) refers to a state of reduced carbon dioxide in the blood. It is usually triggered by breathing too deeply or rapidly, in excess of the metabolic demand. The end result is that alveolar and arterial carbon dioxide (CO 2 ) pressures decrease and blood pH increases. Sustained hyperventilation produces a variety of adverse changes, including a diminished ability for oxygen to pass from the blood to the organism's cells.

Isomorphism (2018)

Abstract Isomorphism refers to the process whereby organizations become increasingly similar over time. There are two main approaches to understanding isomorphism: competitive and institutional. Competitive isomorphism refers to the isomorphism that occurs due to competition between organizations in a system for survival. There are three forms of institutional isomorphism: coercive, mimetic, and normative. Once fields become established, these processes of isomorphism lead to homogenization of the organizations in the field over time.
Alkoxido, Amido, and Imido Derivatives of Titanium(IV) Tetratolylporphyrin (1997)

Treatment of (TTP)TiCl2 (1) [TTP = meso-5,10,15,20-tetra-p-tolylporphyrinato dianion] with excess NaOR (R = Ph, Me, t-Bu) affords the bis(alkoxide) derivatives (TTP)Ti(OR)2 [R = Ph (2), Me (3), t-Bu (4)] in moderate yield. The corresponding amido derivative (TTP)Ti(NPh2)2 (5) is prepared in an analogous fashion employing LiNPh2. The disubstituted complexes 2, 3, and 5 react cleanly with (TTP)TiCl2 to afford the ligand exchange products (TTP)Ti(OR)Cl [R = Ph (6), Me (7)] and (TTP)Ti(NPh2)Cl (8), respectively. The monosubstituted complexes 6−8 are also obtained by treatment of 1 with 1 equiv of the appropriate NaOR or LiNPh2 reagent. Treatment of 5 with excess phenol produces the bis(phenoxide) derivative 2 and 2 equiv of HNPh2. The imido derivatives (TTP)TiNR [R = t-Bu (9), Ph (10), C6H4-p-Me (11)] are prepared by the treatment of 1 with excess LiNHR. The t-Bu derivative (9) is also obtained by reaction of 1 with excess H2N-t-Bu at elevated temperatures. The phenyl imido complex (10) may be produced by the reaction of 0.5 equiv of PhNNPh with (TTP)Ti(η2-EtC⋮CEt) in refluxing toluene. Finally, (TTP)TiNTMS (12) is obtained by oxidation of (TTP)Ti(η2-EtC⋮CEt) with N3TMS.
Evaluation of Parylene as Protection Layer for Capacitive Micromachined Ultrasonic Transducers (2008)

Due to their enhanced performance, capacitive Micromachined Ultrasonic Transducers (cMUTs) are on the way to replacing standard piezoelectric ceramics technology in ultrasound medical imaging. The cMUT device requires the implementation of a final protection layer in order to avoid electrode degradation and achieve biocompatibility. Parylene C is a material of choice for such applications as it can be deposited in exceptionally conformal and chemically inert thin films. In this work, the influence of 1µm thick protective coating of Parylene film on cMUT performance and reliability is studied through simulations and dynamic characterization. Data obtained by laser Doppler vibrometry show a good agreement between simulations and experiments with a slight increase of the collapse voltage. Device ageing provides evidence of the necessity and the effectiveness of Parylene as a protective layer. Finally, this work reveals that cMUT resonant frequency can be easily tuned by controlling the deposited Parylene film thickness.
