Multiscale Representation and Compression of 3-D Point Data (2008)

A compact representation scheme is presented for 3-D point data. To describe underlying surface from raw point samples, we dyadically divide a 3-D domain enclosing whole points. Then, local points in each cube are approximated by a plane patch, yielding a multiscale representation of 3-D surface. To reduce the redundancy between different scale models, the geometry innovation is evaluated between different scale planes, which reveals the Euclidian distance between planes. Finally, the geometry innovation coefficients are compressed by a zerotree-based encoder. Based on the multiscale plane representation of 3-D geometry and the efficient plane decomposition method, the proposed scheme provides a desirable framework for 3-D point geometry processing.
SPaRe: selective partial replication for concurrent fault detection in FSMs (2003)

We propose a non-intrusive methodology for concurrent fault detection in FSMs. The proposed method is similar to duplication, wherein a replica of the circuit acts as a predictor that immediately detects potential faults by comparison to the original FSM. However, instead of duplicating the FSM, the proposed method selects a few prediction functions which only partially replicate it. Selection is guided by the objective of minimizing the incurred hardware overhead without compromising the ability to detect all faults, yet possibly introducing fault detection latency. Furthermore, in contrast to concurrent error detection approaches which presume the ability to re-synthesize the FSM and exploit parity-based state encoding, the proposed method does not interfere with the encoding and implementation of the original FSM. Experimental results indicate that the proposed method achieves significant hardware overhead reduction over duplication, while detecting more than 99% of all permanent faults with very low average fault detection latency.
About Face: A Perspective on Civilian Military Relations through the Lens of the Principal-Agent Theory (2014)

- 55 - About Face: A Perspective of Civil-Military Relations through the Lens of Principal-Agent Theory Randall D. Swain Eastern Kentucky University This essay uses the principal-agent theory to offer a framework for explaining shirking tendencies by the U.S. military in civil-military relations. Through the lens of the framework presented here, the principal-agent theory explains why shirking tendencies by the U.S. military is more likely to occur when a Republican occupies the White House, than when it is occupied by a Democrat. Besides providing a framework for conceptualizing civil-military relations, the importance of this work lies in the manner in which the principal-agent theory is applied. While the majority of inquiries into principal-agent theory focuses on executive control of bureaucratic agencies that have domestic policy agendas, this is one of the few—if any—that uses principal-agent theory to examine executive control of an agency (the U.S. Military) that has a foreign policy related agenda.
<title>Motion estimation by scene adaptive block matching and illumination correction</title> (1990)

For low bit rate coding of moving video motion information has to be exploited. Motion estimation algorithms to be used in hybrid coding schemes with motion compensated prediction, e.g. three-step block matching, are chosen with regard to computational requirements and/or estimation accuracy. But all algorithms, once employed, remain fixed throughout coder operation and therefore lack any means of adaptivity to the scene. The computational complexity of a block matching motion estimation scheme is directly proportional to the number of search positions. Every search position requires the calculation of the error criterion. Employing codebook generation techniques, as known from vector quantization, the selection and total number of search positions can be optimized by a vedorbook design. The vectorbook may be tailored to the computational requirements. It can be switched adaptively during coder operation (on-the-fly), in order to trade matching accuracy against computational complexity. The vector-book also may be altered adaptively to substitute rarely needed search positions by those, which are better suited for coding of the actual scene. Due to the error criterion which is based on averaged differences ,the reliability of the displacement vector field is strongly affected by changes in the overall illumination of a scene. Upon a change in mean brightness, usually blocks are moved in order to fit the average brightness, to some degree regardless of the image structures inside the block. By an illumination correction interlaced with motion estimation, block matching always works on mean-removed blocks.

Fabrication of periodic structures in thin metal films by pulsed laser irradiation (2007)

We developed a technique for the fabrication of 1D and 2D periodic structures in thin gold and silver films by irradiation with two and four intersecting beams of a nanosecond pulsed laser. The periodically alternating intensity distribution caused by interference induces mass transfer in thin metal films. The mechanisms and kinetics of mass transfer depend on the film thickness, morphology, and laser intensity. In the films thinner than some transitional value, h*, redistribution of material between "hot" and "cold" regions on the substrate occurs as a result of melting and beading of the film in "hot" regions and subsequent motion of liquid drops towards "cold" regions in the optically induced temperature gradient. In the films thicker h* redistribution of the film material occurs by hydrodynamic flow of the molten film in the temperature gradient, with subsequent crystallization in the "cold" regions and formation of tall and narrow ridges or rims. Theoretical models were developed that allowed us to calculate the time dependent temperature distributions around irradiated regions of the film. From the temperature distributions we calculated the expected speed of liquid beads, as well the distances between the ridges, the rim diameters and found good agreement with the measured values.
A GaAs cermet gate charge-coupled device (2010)

The design, implementation and evaluation of a 64-pixel, 4-phase GaAs cermet gate charge-coupled device ( CMCCD ) are described. It is demonstrated that the signal charge confinement and the signal charge capacity of the CMCCD are maximized when thin, highly doped active layers are used for implementing the device. The cermet/GaAs junction within an interelectrode gap of the CMCCD forms a barrier similar to a metal/GaAs Schottky barrier, as revealed by an investigation of the dc current-voltage characteristic of a cermet/GaAs Schottky barrier diode. A transmission line model is described for the cermet/GaAs junction within an interelectrode gap of the CMCCD and is used to demonstrate the relationship of the surface potential variation along the gap as a function of the clock frequency and the material parameters. It is shown that the surface potential variation is monotonic for all frequencies, which is desirable for minimizing the formation of energy troughs within the active layer. Energy troughs trap and release charge from passing charge packets, causing unwanted signal dispersion. A two-dimensional computer model is used to determine a theoretical maximum frequency of operation of the CMCCD. It is shown that a short transport electrode length for a fixed transport electrode pitch is preferable as it results in the maximum high frequency performance of the CMCCD for the lowest clock power. A computer simulation of a single electrode transfer of a charge packet is demonstrated using the two-dimensional computer model. The computer simulation indicates that efficient charge transfer takes place, suggesting that the CMCCD will have good performance. A GaAs CMCCD with an on-chip GaAs MESFET source follower amplifier has been produced using a six mask level fabrication procedure. The CMCCD and the output source follower amplifier are demonstrated to operate at 100 MHz. Charge transfer efficiencies of 1.00 and 0.998 for 100 MHz operation are obtained for the CMCCD using the impulse response method and the insertion loss method.

Security issues in the development of a wireless blood-glucose monitoring system (2003)

This paper is a progress report on an ongoing research effort that makes use of wireless biometric data management, specifically a wireless blood-glucose monitoring system (WBgM). The goal of this research is to realize appropriate timely intervention by health-care providers in response to records of unregulated blood-glucose level in order to maintain near-normal levels. The focus of this paper is security-their is the possibility that medical information may be used consciously by malicious eavesdropper to the detriment of a patient in search of new employment or a new insurer. There is the possibility of malicious or accidental data corruption from database intrusion. Mobile data transmission is especially problematic in preventing these. We present requirements and our approach taken to realize a secure system architecture. Key techniques and their implementation details to maintain privacy, authentication, and data integrity are discussed here.
An IPv6-based location management scheme for client-server computing over mobile data networks (2003)

Mobility management is an essential component in enabling mobile hosts to move seamlessly from one location to another while maintaining the packet routing efficiency between the corresponding hosts. One of the concerns raised with the IETF Mobile IP standard is the excessive signaling generated for highly mobile computers. This paper introduces a scheme to address that issue by manipulating the inherent client-server interaction which exists in most applications to provide the correspondent host with the current mobile host binding. To evaluate the performance of our scheme, we simulate typical Internet application sessions involving a mobile host and examine the signaling and routing costs. Results show a reduction in the overhead for delivering packets to the mobile host.
The Plastidic Bile Acid Transporter 5 Is Required for the Biosynthesis of Methionine-Derived Glucosinolates in <i>Arabidopsis thaliana</i>   (2009)

Aliphatic glucosinolate biosynthesis is highly compartmentalized, requiring import of 2-keto acids or amino acids into chloroplasts for side chain elongation and export of the resulting compounds into the cytosol for conversion into glucosinolate. Aliphatic glucosinolate biosynthesis in Arabidopsis thaliana is regulated by three R2R3-MYB transcription factors, the major player being High Aliphatic Glucosinolate 1 (HAG1/MYB28). Here, we show that BAT5, which belongs to the putative bile acid transporter family, is the only member of this family that is transactivated by HAG1/MYB28, HAG2/MYB76, and HAG3/MYB29. Furthermore, two isopropylmalate isomerases genes, IPMI1 and IPMI2, and the isopropylmalate dehydrogenase gene, IPMDH1, were identified as targets of HAG1/MYB28 and the corresponding proteins localized to plastids, suggesting a role in plastidic chain elongation reactions. The BAT proteins also localized to plastids; however, only mutants defective in BAT5 function contained strongly reduced levels of aliphatic glucosinolates. The bat5 mutant chemotype was rescued by induced overexpression of BAT5. Feeding experiments using 2-keto acids and amino acids of different chain length suggest that BAT5 is a plastidic transporter of (chain-elongated) 2-keto acids. Mechanical stimuli and methyl jasmonate transiently induced BAT5 expression in inflorescences and leaves. Thus, BAT5 was identified as the first transporter component of the aliphatic glucosinolate biosynthetic pathway.
Optimal control of affine nonlinear continuous-time systems using an online Hamilton-Jacobi-Isaacs formulation (2010)

Solving the Hamilton-Jacobi-Isaacs (HJI) equation, commonly used in H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> optimal control, is often referred to as a two-player differential game where one player tries to minimize the cost function while the other tries to maximize it. In this paper, the HJI equation is formulated online and forward-in-time using a novel single online approximator (SOLA)-based scheme to achieve optimal regulation and tracking control of affine nonlinear continuous-time systems. The SOLA-based adaptive approach is designed to learn the infinite horizon HJI equation, the corresponding optimal control input, and the worst case disturbance. A novel parameter tuning algorithm is derived which not only achieves the optimal cost function, control input, and the disturbance, but also ensures the system states remain bounded during the online learning. Lyapunov methods are used to show that all signals are uniformly ultimately bounded (UUB) while ensuring the approximated signals approach their optimal values with small bounded error. In the absence of OLA reconstruction errors, asymptotic convergence to the optimal signals is demonstrated, and simulation results illustrate the effectiveness of the approach.
Interaction between Dilazep and &alpha;-Adrenoceptors (1984)

Dilazep, 1,4-bis-[3-(3,4,5-trimethoxybenzoyl-oxy)propyl]perhydro-1,4-diazep ine, is a novel antianginal agent with an unusual chemical structure. The drug is a weak calcium antagonist. In pithed rats dilazep (10-100 mg/kg i.v.) caused a transient hypotensive effect which was accompanied by a strong and persistent reduction in heart rate. Similarly as observed for other, more potent calcium antagonists dilazep (10-100 mg/kg) counteracted the vasoconstriction, evoked by the stimulation of postsynaptic alpha 2-adrenoceptors with the selective agonist B-HT 920. The antagonism proved noncompetitive. The vasoconstriction, induced upon selective stimulation of postsynaptic alpha 1-adrenoceptors with methoxamine, however, was hardly influenced by dilazep. These findings are in accordance with the calcium-antagonistic activity of dilazep, demonstrable at relatively high doses. From radioligand-binding studies it was concluded that dilazep is an extremely weak antagonist of alpha 1-adrenoceptors, whereas it does not possess any measurable affinity towards alpha 2-adrenoceptors. It seems unlikely that the antianginal activity of dilazep can be fully explained by its weak calcium-antagonistic potency. However, the bradycardic effect of dilazep is probably relevant to its antianginal activity.
Reactive grafting of glycidyl methacrylate onto polypropylene (2010)

Abstract This work explored the melt‐phase grafting of glycidyl methacrylate (GMA) onto polypropylene on a closely intermeshing corotating twin‐screw extruder (16‐mm screws, 40 : 1 length/diameter ratio). The modification of the base polypropylene to produce GMA‐grafted polypropylene was achieved via peroxide‐induced hydrogen abstraction from the polypropylene followed by the grafting of the GMA monomer or by the grafting of styrene followed by copolymerization with the GMA. In this study, both the position and order of the reactant addition were investigated as a route to improving graft yields and reducing side reactions (degradation). For the peroxide–GMA system, adding GMA to the melt before the peroxide resulted in significant improvements in the graft levels because of the improved dispersion of GMA in the melt. The addition of a comonomer (styrene) was explored as a second route to improving the graft yield. Although the addition of the comonomer led to a considerable rise in the level of grafted GMA, altering the order of the reactant addition was not found to contribute to an increase in the grafted GMA levels. However, variable levels of grafted styrene were achieved, and this may play an important role in the development of grafted polymers to suit specific needs. © 2010 Wiley Periodicals, Inc.

Image Retargeting Using Mesh Parametrization (2009)

Image retargeting aims to adapt images to displays of small sizes and different aspect ratios. Effective retargeting requires emphasizing the important content while retaining surrounding context with minimal visual distortion. In this paper, we present such an effective image retargeting method using saliency-based mesh parametrization. Our method first constructs a mesh image representation that is consistent with the underlying image structures. Such a mesh representation enables easy preservation of image structures during retargeting since it captures underlying image structures. Based on this mesh representation, we formulate the problem of retargeting an image to a desired size as a constrained image mesh parametrization problem that aims at finding a homomorphous target mesh with desired size. Specifically, to emphasize salient objects and minimize visual distortion, we associate image saliency into the image mesh and regard image structure as constraints for mesh parametrization. Through a stretch-based mesh parametrization process we obtain the homomorphous target mesh, which is then used to render the target image by texture mapping. The effectiveness of our algorithm is demonstrated by experiments.

MARGE allows users to annotate real world locations with multimedia content, and concurrently, provide opportunities for play through creating and engaging interactive game elements, earning currency, and socializing. A study of MARGE was conducted. The results suggest the potential of the application in terms of entertainment and content sharing value. Participants felt that the features in MARGE were able to support the objectives of content sharing and gaming, and that the idea of gaming could be a motivator for content sharing. Implications and future research directions are discussed.
STORAGE TYPES IN THE SEMANTIC BINARY DATABASE ENGINE (2005)

Modern database engines support a wide variety of data types. Native support for all of the types is desirable and convenient for the database application developer, as it allows application data to be stored in the database without further conversion. However, support for each data type adds complexity to the database engine code. To achieve a compromise between convenience and complexity, the semantic binary database engine is designed to support only the binary data type in its kernel. Other data types are supported in the user-level environment by add-on modules. This solution allows us to keep the database kernel small and ensures the stability and robustness of the database engine as a whole. By providing extra database tools, it also allows application designers to get database-wide support for additional data types.
To Scan or Not to Scan: The Question of Consumer Behavior and QR Codes on Food Packages (2019)

We conducted a field experiment involving the purchase of oysters to offer market-based evidence on whether consumers will scan quick response (QR) codes on food packages, a new labeling technology proposed by the SmartLabelTM initiative. In an artefactual marketplace selling oysters, only 1.2% participants scanned the QR code labels with their own devices. However, providing free access to a QR-scanning smartphone induced 52.6% of participants to access labeling information—a large improvement even compared to when this information was provided directly on the package. Furthermore, consumers’ responses to the additional information were similar regardless of how the information was delivered.
Distributed Dynamic Spectrum Allocation for Secondary Users in a Vertical Spectrum Sharing Scenario (2012)

In this paper, we study the problem of distributed spectrum allocation under a vertical spectrum sharing scenario in a cognitive radio network. The secondary users share the spectrum licensed to the primary user by observing the activity statistics of the primary users, and regulate their transmission strategy in order to abide by the spectrum sharing etiquette. When the primary user is inactive in a subset of the available frequency bands, from the perspective of the secondary users the problem reduces to a distributed horizontal spectrum sharing. For a specific class of networks, the latter problem is addressed by the recently proposed GADIA algorithm [1]. In this paper, we present analytical and numerical results on the performance of the GADIA algorithm in conjunction with the above-mentioned vertical spectrum sharing scenario. These results reveal near-optimal performance guarantees for the overall vertical spectrum sharing scenario.
