A Runtime Adaptation Framework for Native C and Bytecode Applications (2006)

The need for self-healing software to respond with a reactive, proactive or preventative action as a result of changes in its environment has added the non-functional requirement of adaptation to the list of facilities expected in self-managing systems. The adaptations we are concerned with assist with problem detection, diagnosis and remediation. Many existing computing systems do not include such adaptation mechanisms, as a result these systems either need to be re-designed to include them or there needs to be a mechanism for retro-fitting these mechanisms. The purpose of the adaptation mechanisms is to ease the job of the system administrator with respect to managing software systems. This paper introduces Kheiron, a framework for facilitating adaptations in running programs in a variety of execution environments without requiring the re-design of the application. Kheiron manipulates compiled C programs running in an unmanaged execution environment as well as programs running in Microsoft's Common Language Runtime and Sun Microsystems' Java Virtual Machine. We present case-studies and experiments that demonstrate the feasibility of using Kheiron to support self-healing systems. We also describe the concepts and techniques used to retro-fit adaptations onto existing systems in the various execution environments.
Elasto-optic polarization measurement in optical fiber (1981)

A method is described for the nondestructive determination of the state of polarization of the guided light at an arbitrary point along a single-mode fiber. The fiber is squeezed laterally with a small, periodic (75-Hz) force. The azimuth of the force is varied. The resulting elasto-optic polarization modulation is detected at the fiber end and is evaluated for the azimuth and ellipticity of the polarization at the point of modulation.
Prognostic Health Management of Aircraft Power Generators (2009)

In this paper, prognostic tools are developed to detect the onset of electrical failures in an aircraft power generator, and to predict the generator's remaining useful life (RUL). Focus is on the rotor circuit since failure mode, effects, and criticality analysis (FMECA) studies indicate that it is a high priority candidate for condition monitoring. A signature feature is developed and tested by seeded fault experiments to verify that the initial stages of rotor faults are observable under diverse generator load conditions. A tracking filter is used to assess the damage state and predict generator RUL. This information helps to avoid unexpected failures while reducing the overall life-cycle cost of the system.

Multi-Linked AODV Routing Protocol for Wireless Mesh Networks (2007)

Nodes in multi-hop wireless networks, and specifically in ad-hoc and mesh networks, are being increasingly equipped with multiple wireless network interfaces (radios) operating on orthogonal channels to achieve better utilisation of the frequency spectrum. In addition to reducing interference via increased channel diversity, these additional interfaces can be used to create multiple concurrent links between adjacent nodes, i.e. nodes within single-hop range of each other. Information about the availability of multiple links between nodes provides the opportunity to increase the overall performance of the network by optimally balancing traffic between the set of available inter- node links. In this paper, we present extensions to the well known Ad-hoc On-demand Distance Vector (AODV) routing protocol with the aim to discover and exploit multiple links in Wireless Mesh Networks. As demonstrated via extensive simulations, Multi-Link AODV (AODV-ML) achieves a more than 100% improvement over standard multi-radio AODV in terms of key performance metrics such as packet delivery ratio, latency and routing overhead.
Fabrication and Characterization of Diamond Quartz Crystal Microbalance Electrode (2002)

Boron-doped diamond film on a quartz crystal electrode was prepared by a reflow technique. The mass sensitivity of this diamond-quartz crystal microbalance (QCM) sensor was determined by performing electrodeposition. This novel electrochemical QCM sensor was quite stable under several electrochemical experimental conditions. Its wide potential window and significantly low background current are just the same as the performance of a diamond electrode. We also showed that the fabricated diamond-QCM electrode worked satisfactorily as a useful tool for electrochemical microgravimetry by examining hydrogen evolution, oxygen evolution, and oxidation of the diamond surface in acidic solutions. It was found that evolved inserted into the bulk of as-grown diamond with a storage volume of 0.06 mol/dm3 in 0.5 M HCl solution, after sweeping the potential from 0 to −3 V at a scan rate of 10 mV/s, in contrast to O-terminated diamond-QCM, which inhibited hydrogen intercalation. © 2002 The Electrochemical Society.

Subeutectic Synthesis of Epitaxial Si-NWs with Diverse Catalysts Using a Novel Si Precursor (2010)

The applicability of a novel silicon precursor with respect to reasonable nanowire (NW) growth rates, feasibility of epitaxial NW growth and versatility with respect to diverse catalysts was investigated. Epitaxial growth of Si-NWs was achieved using octochlorotrisilane (OCTS) as Si precursor and Au as catalyst. In contrast to the synthesis approach with SiCl(4) as precursor, OCTS provides Si without the addition of H(2). By optimizing the growth conditions, effective NW synthesis is shown for alternative catalysts, in particular, Cu, Ag, Ni, and Pt with the latter two being compatible to complementary metal-oxide-semiconductor technology. As for these catalysts, the growth temperatures are lower than the lowest liquid eutectic; we suggest that the catalyst particle is in the solid state during NW growth and that a solid-phase diffusion process, either in the bulk, on the surface, or both, must be responsible for NW nucleation.
Arteriographically Determined Occlusive Disease within the Hypogastric-Cavernous Bed in Impotent Patients Following Blunt Perineal and Pelvic Trauma (1990)

To determine the presence, location and pattern of arterial occlusive disease within the hypogastric-cavernous arterial bed in impotent men following blunt perineal and pelvic trauma, we reviewed the selective internal pudendal arteriograms of 20 patients with a history of blunt perineal and 7 with blunt pelvic trauma who had immediate development of impotence. Arteriographic studies of 104 other impotent patients also were reviewed and compared. Patients with persistent impotence immediately after blunt pelvic and perineal trauma had significantly different patterns of arteriographically demonstrated occlusive disease within the distal hypogastric-cavernous arterial bed consistent with the site of the traumatic injury. Those who sustained blunt pelvic trauma and complained of immediate impotence revealed arterial occlusive lesions mainly in the internal pudendal, common penile, cavernous and dorsal arteries. The incidence of arterial lesions in the distal internal pudendal or common penile artery was significantly higher (p less than 0.01) in patients with blunt pelvic trauma (92%) than in those with blunt perineal trauma (35%). Patients who sustained blunt perineal trauma and complained of immediate impotence demonstrated a more focal pattern of pathological arterial occlusion primarily in the cavernous and dorsal arteries. The incidence of a solitary arterial lesion in the cavernous artery without proximal disease was significantly higher (p less than 0.05) in patients with blunt perineal trauma (48%) than in those with blunt pelvic trauma (8%). It is hypothesized that blunt trauma without immediate impotence may be a potential risk factor for later development of arterial vasculogenic impotence, and that unrecognized or seemingly innocuous trauma may be a factor in cases of idiopathic impotence. Patients without trauma and with vascular risk factors have a more diffuse pattern of arteriographically demonstrated arterial lesions.
Spray and Focus: Efficient Mobility-Assisted Routing for Heterogeneous and Correlated Mobility (2007)

Intermittently connected mobile networks are wireless networks where most of the time there does not exist a complete path from the source to the destination. There are many real networks that follow this model, for example, wildlife tracking sensor networks, military networks, vehicular ad hoc networks (VANETs), etc. To deal with such networks researchers have suggested to use controlled replication or "spraying " methods that can reduce the overhead of flooding-based schemes by distributing a small number of copies to only a few relays. These relays then "look" for the destination in parallel as they move into the network. Although such schemes can perform well in scenarios with high mobility (e.g. VANETs), they struggle in situations were mobility is slow and correlated in space and/or time. To route messages efficiently in such networks, we propose a scheme that also distributes a small number of copies to few relays. However, each relay can then forward its copy further using a single-copy utility-based scheme, instead of naively waiting to deliver it to the destination itself. This scheme exploits all the advantages of controlled replication, but is also able to identify appropriate forwarding opportunities that could deliver the message faster. Simulation results for traditional mobility models, as well as for a more realistic "community-based" model, indicate that our scheme can reduce the delay of existing spraying techniques up to 20 times in some scenarios
Near-Infrared Fluorescence Probes for Enzymes Based on Binding Affinity Modulation of Squarylium Dye Scaffold (2012)

We present a novel design strategy for near-infrared (NIR) fluorescence probes utilizing dye-protein interaction as a trigger for fluorescence enhancement. The design principle involves modification of a polymethine dye with cleavable functional groups that reduce the dye's protein-binding affinity. When these functional groups are removed by specific interaction with the target enzymes, the dye's protein affinity is restored, protein binding occurs, and the dye's fluorescence is strongly enhanced. To validate this strategy, we first designed and synthesized an alkaline phosphatase (ALP) sensor by introducing phosphate into the squarylium dye scaffold; this sensor was able to detect ALP-labeled secondary antibodies in Western blotting analysis. Second, we synthesized a probe for β-galactosidase (widely used as a reporter of gene expression) by means of β-galactosyl substitution of the squarylium scaffold; this sensor was able to visualize β-galactosidase activity both in vitro and in vivo. Our strategy should be applicable to obtain NIR fluorescence probes for a wide range of target enzymes.
Quinone-based fluorophores for imaging biological processes (2017)

Quinones are privileged chemical structures playing crucial roles as redox and alkylating agents in a wide range of processes in cells. The broad functional array of quinones has prompted the development of new chemical approaches, including C-H bond activation and asymmetric reactions, to generate probes for examining their activity by means of fluorescence imaging. This tutorial review covers recent advances in the design, synthesis and applications of quinone-based fluorescent agents for visualizing specific processes in multiple biological systems, from cells to tissues and complex organisms in vivo.
Phase efficiency of the reflective array antenna (1995)

A reflective array consists of a large number of passive phase shifting elements placed on a plane or a conformal surface. Each element provides a total reflection to an incident wave with a certain phase shift. By choosing the phase shift of each element properly, the energy of an incident plane wave can be focused into a feedhorn placed in front of the array, thus producing a reflector antenna. A systematic theory on the phase efficiency of planar reflective array antennas is given and two kinds of arrays with element phase shifting values chosen from a continuous or quantised range are studied. The relationship between the phase efficiency, element size and the focal-length-to-diameter ratio is discussed. The influences of phase quantisation error and the manufacturing and installation tolerance on the phase efficiency are analysed using probability theory. A new reflective phase correcting array with multilayer dielectric tiles is presented. Experimental results agree well with the theoretical predictions.
Intramolecular Quenching of the Photofading of Some Dyes (1985)

Some dyes containing a nickel sulphonate intramolecular singlet‐oxygen quenching group have been synthesised and the influence of such a substituent on the photofading of the dyes examined. Dyes containing this quenching group showed improved resistance to photofading in the adsorbed state in visible light.
Butterfly and Benes-Based on-Chip Communication Networks for Multiprocessor Turbo Decoding (2007)

Several research activities have recently emerged aiming to propose multiprocessor implementations in order to achieve flexible and high throughput parallel iterative decoding. Besides application algorithm optimizations and application-specific instruction-set processor design, the on-chip communication network constitutes a major issue in this application domain. In this paper, the authors propose to use multistage interconnection networks as on-chip communication networks for parallel turbo decoding. Adapted benes and butterfly networks are proposed with detailed hardware implementation of network interfaces, routers, and topologies. In addition, appropriate packet format and routing for interleaved/deinterleaved extrinsic information exchanges are proposed. The flexibility of these on-chip communication networks enables their use for all turbo code standards and constitutes a promising feature for their reuse for any similar interleaved/deinterleaved iterative communication profile
Comparison of pulsed and downstream deposition of fluorocarbon materials from C3F8 and c-C4F8 plasmas (2004)

Materials deposited in continuous wave (cw) and pulsed low-pressure octafluoropropane (C3F8) and octafluorocyclobutane (c-C4F8) plasmas were characterized using Fourier transform infrared spectroscopy (FTIR), x-ray photoelectron spectroscopy, static contact angle measurements, spectroscopic ellipsometry, and scanning electron microscopy (SEM). Fluorocarbon (FC) materials deposited in pulsed plasmas were less crosslinked than those deposited in cw plasmas with equivalent input powers. Within each system, higher F/C ratio materials were deposited by lowering the plasma input power/duty cycle. Using downstream depositions had a similar effect on film composition, but also resulted in decreased deposition rates. SEM analysis showed that decreases in the flexibility of the fluorocarbon films were correlated with increases in the percent of crosslinking. Additionally, the smoothness of the film surfaces suggests that polymerization processes occur on the substrate surface. Overall, films deposited in C4F8 plasmas were more crosslinked and less flexible than those deposited in C3F8 plasmas under the same conditions. The composition of the deposited FC films is correlated to the nature and relative concentrations of nascent ions previously measured in these plasma systems using plasma ion mass spectrometry.
Highly Stretchable Polymer-based Optical Strain Sensor for Integration with Soft Actuator (2019)

This paper introduces a polymer-based optical strain sensor that has large stretchability. For measuring strain of 100%, we have designed the stretchable sensor by embedding a waved optical fiber into soft polymer substrate. Inducing loss of intensity of light passes through the optical fiber by variation of bending curvature, the sensor can estimate its strain from the magnitude of output light intensity.
Routing in multiple domain networks (1989)

An investigation is conducted of routing in packet-switched networks that consist of two individually controlled domains. Each domain controller determines a static routing plan for requirements that are contained within its domain and for requirements that are addressed to nodes in the other domain. The authors propose two routing algorithms, assuming that each controller has limited information on the configuration of the other domain. Numerical examples are provided that compare the delay performance of such algorithms with the optimal routing of a centralized scheme that has full information and control over both domains. Implications of distributed control on network design are explored.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Schedule evaluation: simulation of JIT performance in a printing shop (2002)

A medium sized UK based academic publishers own a subsidiary printing business. Presently the Academic Printers (AP) is experiencing productions line flow problems reducing the efficiency of the operation. Most of the problems are generated by the imbalanced workflow through the system. By implementing a JIT production planning system it is hoped that some of the production problems can be resolved. Using the simulation software a model was created to investigate the performance of the AP under a variety of operating conditions. Results showed that operating the system with JIT control would not produce economic performance improvements due to constraints applied by the printing process.
Models of Ontogenetic Development for Autonomous Adaptive Systems (2001)

Biological organisms display an amazing ability during their ontogenetic development to adaptively develop solutions to the various problems of survival that their environments present to them. Dynamical and embodied models of cognition (Clark, 1997; Edelman &amp; Tononi, 2000; Franklin, 1995; Freeman, 1999a, 1999b; Freeman &amp; Kozma, 2000; Freeman, Kozma, &amp; Werbos, 2000; Hendriks-Jansen, 1996; Kelso, 1995; Kozma &amp; Freeman, 2001; Port &amp; van Gelder, 1995; Skarda &amp; Freeman, 1987; Thelen &amp; Smith, 1994) are beginning to offer new insights into how the numerous, heterogeneous elements of neural structures may self-organize during the development of the organism in order to effectively form adaptive categories and increasingly sophisticated skills, strategies and goals. In this paper we present models of ontogenetic development built on neurologically inspired, bottom-up, dynamic approaches to embodied category formation such as those done by Freeman (1975, 1999b), Freeman and Kozma (2000), Kozma and Freeman (2001), Verschure (1998) and Edelman (1987, 1989). We believe that building on such mechanisms from an embodied dynamical perspective will produce autonomous agents that display greatly increased flexibility in their behavior. Such models will represent a better understanding of how the brains of biological organisms not only form perceptual categories of their environments during development, but also develop effective patterns of behavior through the dynamic self-organization of neurological patterns of activity.
A Bayesian-networks-based approach for managing uncertainty in location-tracking applications (2004)

In this paper we present a probabilistic model for managing uncertainty in location-tracking applications. Our technique tries to capitalize on the fact that humans are creatures of habit, which makes it possible to predict how a person would react in a certain situation, based on his/her history. Since the moving objects (MO) we are interested in here are humans, we refer to this subset of MO as roving users or RU. Our approach is based on using Bayesian networks to model the RU behavior and preferences. This user model is then used to predict his/her actions allowing the system to more accurately determine his/her location between location reports or in the near future. Our technique estimates the location of a RU based on the last location reported, the user model, and knowledge about the current state of affairs. We present the results of a simulation we performed comparing the accuracy of location estimation of a popular technique to that of our proposed probabilistic technique.
Ereignismanagement, Medienresonanz und Konfliktdynamik (2001)

Medien nehmen in öffentlichen Auseinandersetzungen eine Schlüsselrolle ein. Sie entscheiden nach medienspezifischen Kriterien, wer sich mit welchen Argumenten an der öffendichen Diskussion beteiligen kann und wirken auch auf diese Weise an der öffentlichen Meinungsbildung mit. Journalisten berichten aber nicht nur neutral über das politische Geschehen, sie nehmen in Kommentaren Stellung und bewerten das (politische) Handeln der Konfliktbeteiligten. Dabei kann die Berichterstattung über den Ausgang eines Konfliktes mitentscheiden (vgl. Kap. 3.2.). Deshalb konkurrieren Konfliktgegner um die Meinungsführerschaft in der Medienberichterstattung. Die erwartete Medienresonanz ist neben anderen Handlungsfolgen einer gewählten oder noch zu wählenden Handlungsalternative eine Handlungskonsequenz, die den Konfliktbeteiligten bei positiver Tendenz Nutzen bringen und bei negativer Kosten verursachen kann.
