A Wavelength and Bandwidth Assignment Algorithm to Support Guaranteed Bandwidth Levels in Hybrid Time Division Multiplexing/Wavelength Division Multiplexing Ethernet Passive Optical Networks

Abstract A novel bandwidth assignment algorithm in wavelength division multiplexing Ethernet passive optical networks, called a dynamic wavelength assignment service level agreement, is proposed to efficiently provide subscriber differentiation. Simulation results show that the dynamic wavelength assignment service level agreement outperforms other bandwidth allocation algorithms in wavelength division multiplexing Ethernet passive optical networks, as it makes a fairer bandwidth distribution than other methods and is able to overcome the non-allowed packet fragmentation of the Ethernet passive optical network standard. Consequently, it greatly increases the achieved throughput and always ensures a minimum guaranteed bandwidth to every priority subscriber. Furthermore, the new algorithm obtains lower mean packet delay and packet loss rate for the highest priority subscribers when compared with other bandwidth distribution schemes in wavelength division multiplexing Ethernet passive optical networks.

An observation of breakdown characteristics on thick silicon oxide

We have investigated the current-voltage characteristics of silicon dioxide (SiO/sub 2/) with its destruction phenomena and the electric damage which would be introduced by a measurement of leakage current. The samples are oxidized at 820/spl deg/C/spl sim/1215/spl deg/C and their thickness is 10 nm/spl sim/1650 nm. We have confirmed that the SiO/sub 2/ film under the electric stress begins to be damaged at a specific electric field strength. This specific value, /spl ap/8 MV/cm for the 75/spl sim/100 nm SiO/sub 2/, is distinctly lower than the dielectric breakdown value and decreases with increasing SiO/sub 2/ thickness. We have found for the first time that the leakage current could suddenly increase up to 100/spl sim/10000 times near the specific electric field strength if the SiO/sub 2/ film was treated above a certain temperature and possesses some thickness. And we suspect that this steep increment of leakage current of SiO/sub 2/ is due to the multiplication phenomenon which is activated by the electron's impact ionization. We have also noticed that the whole current-voltage characteristic of SiO/sub 2/ films is very similar to that of high voltage silicon pn-diodes in the whole range from the very low leakage current to the destruction phenomenon.
Z‐Thickness Blending: Effective Fragment Merging for Multi‐Fragment Rendering

An effective fragment merging technique is presented in this study that addresses multi‐fragment problems, including fragment overflow and z‐fighting, and provides visual effects that are beneficial for various screen‐space rendering algorithms. The proposed method merges locally adjacent fragments along the viewing direction to resolve the aforementioned problems based on cost‐effective multi‐layer representation and coplanar blending. We introduce a z‐thickness model based on the radiosity spreading from the viewing z‐direction. Moreover, we present the fragment‐merging schemes and rules for determining the visibility of the merged fragments based on the proposed z‐thickness model. The proposed method is targeted at multi‐fragment rendering that handles individual fragments (e.g., k‐buffer) instead of representing the fragments as an approximated transmittance function. In addition, our method provides a smooth visibility transition across overlapping fragments, resulting in visual advantages in various visualization applications. In this paper, we demonstrate the advantages of the proposed method through several screen‐space rendering applications.
Dynamic modelling of battery energy storage system and application to power system stability

A useful and systematic dynamic model of a battery energy storage system (BES) is developed for a large-scale power system stability study. The model takes into account converter equivalent circuits, battery characteristics and internal losses. Both charging mode and discharging mode are presented. The model is expressed in equivalent transfer function blocks, and it can be easily used in dynamic stability analysis of a power system. To examine the dynamic behaviour of the model, applications to the damping of turbogenerator torsional oscillations are performed. Active and reactive power modulation by the BES can be controlled according to system requirements. Eigenvalue analysis and dynamic simulations are performed to demonstrate the damping effect of the BES.
Multichannel fiber optic heterodyne interferometer for the acoustic detection of partial discharges

A multichannel interferometric system is proposed for the ultrasonic detection of partial discharges using intrinsic fiber optic sensors that may be immersed in oil. It is based on a heterodyne scheme which drives at least four sensor heads in order to localize the source of the acoustic emissions. The optoelectronic implementation and the experimental tests are presented to optimize the resolution (4 channels - 4 mrad). In addition, the results of ultrasound measurements at 150- kHz with an optical fiber sensor immersed in water in an acoustic test bench are shown, in which a resolution better than 10 Pa was obtained.
Adaptive Practical Fixed-Time Synchronization Control for Bilateral Teleoperation System With Prescribed Performance

In this brief, an adaptive practical fixed-time synchronization control scheme for position tracking of a bilateral teleoperation system with prescribed performance is proposed. A prescribed performance function (PPF) is incorporated into the fixed-time control framework such that the synchronization errors will converge into a residual set in a fixed time and the upper bound of setting time is regardless of the initial states. The upper bound of system uncertainties is estimated via adaptive technique such that the adverse effect induced by system uncertainties can be attenuated. Simulation studies and experiments demonstrate the effectiveness and practicality of the proposed control scheme in terms of both transient and steady-state performance.
Vibration Analysis of Randomly Oriented Carbon Nanotube Based on FGM Beam Using Timoshenko Theory

The carbon nanotube (CNT) reinforced functionally graded materials (FGM) are expected to be the new generation materials having wide range of unexplored potential applications in various technological areas such as aerospace and structural and chemical industry. The present work deals with the finite element modeling and free vibration analysis of CNT based functionally graded beam using three-dimensional Timoshenko beam theory. It has been assumed that the material properties of CNT based FG beam vary only along the thickness and these properties are evaluated by rule of mixture. The extended Hamilton principle has been applied to find out the governing equations of CNT based FG beam. Finite element method is used to solve governing equation with the exact shape functions. Initial analysis deals with CNTs assumed to be oriented along the length direction only. But practically it is not possible. So, further work deals with the free vibration analysis of functionally graded nanocomposite beams reinforced by randomly oriented straight single walled carbon nanotubes (SWCNTs). The Eshelby-Mori-Tanaka approach based on an equivalent fiber is used to investigate the material properties of the beam. Results are presented in tabular and graphical forms to show the effects of carbon nanotube orientations, slenderness ratios, and boundary conditions on the dynamic behavior of the beam.
Write equalization in future tape channels

The characteristics of advanced write- and nonequalized tape channels have been modeled and evaluated to investigate the impact of the equalization on future tape channels, realizing that several factors regarding write-equalization (WE) should be taken into account. It is found that the use of WE can improve nonlinear distortion in the write process and reduce read-equalizer requirements even for media with a moment (M/sub R//spl delta/) as low as 1 memu/cm/sup 2/, and may therefore continue to offer advantages to future thin metal-particle tape systems.
Main inductances of induction motor for diagnostically specialized mathematical models

In the paper modeling of main inductances for mathematical models of induc- tion motors is applied to study the effects caused by a rotor eccentricity and saturation ef- fects. All three possible types of eccentricity: static, dynamic and mixed are modeled. The most important parameters describing rotor eccentricity include self and mutual in- ductances of the windings. The structural changes of the permeance function as a result of eccentricity appearance and the Fourier spectra of inductances in occurrence of satura- tion for each case are determined in the paper. The presented algorithm can be used for the diagnostically specialized models of induction motors.
Amide-Linked Dendron-based Amphiphiles: A class of pH sensitive and highly biocompatible drug carrier for sustained drug release

ABSTRACT PG-dendritic amide-linked amphiphilic micelles were studied to increase the solubility of hydrophobic molecules. The encapsulation study was done by utilising hydrophobic pyrene dye using U.V. technique. The encapsulation efficiency of the non-ionic amphiphiles was obtained at neutral p.H. and at room temperature (p.H. 7.0 & 28 °C). The G.3 dendron-based non-ionic oleic (C18-cis)-amphiphile was found to have the 78.2% encapsulation efficiency. Studies show that the amide-linked G.1 dendron-based non-ionic (C18-cis) amphiphiles have sustained dye release percentage of 78.00% at p.H. 6.2 and 26.19% at p.H. 7.0 in 72 h at 37 °C. The in vitro cyto-toxicological studies showed that after 24–48 h treatment, the G.1 amide amphiphiles exhibit more than 80% of cell viability for concentration as high as 31.25 μg/mL. The cellular uptake was demonstrated using Coumarin 6. The integrated amphiphiles are biocompatible and can be used in the biomedical field as medication encapsulation and target drug delivery.

Optimal seismic design of steel frame buildings based on life cycle cost considerations

A multi‐objective optimization procedure is presented for designing steel moment resisting frame buildings within a performance‐based seismic design framework. Life cycle costs are considered by treating the initial material costs and lifetime seismic damage costs as two separate objectives. Practical design/construction complexity, important but difficult to be included in initial cost analysis, is taken into due account by a proposed diversity index as another objective. Structural members are selected from a database of commercially available wide flange steel sections. Current seismic design criteria (AISC‐LRFD seismic provisions and 1997 NEHRP provisions) are used to check the validity of any design alternative. Seismic performance, in terms of the maximum inter‐storey drift ratio, of a code‐verified design is evaluated using an equivalent single‐degree‐of‐freedom system obtained through a static pushover analysis of the original multi‐degree‐of‐freedom frame building. A simple genetic algorithm code is used to find a Pareto optimal design set. A numerical example of designing a five‐storey perimeter steel frame building is provided using the proposed procedure. It is found that a wide range of valid design alternatives exists, from which a decision maker selects the one that balances different objectives in the most preferred way.

The Use of BIM in Project Planning and Scheduling in the Australian Construction Industry

The Building Information Modeling (BIM) technology is relatively mature when used as a pre-construction design tool, but has not been widely used in the construction phase due to a range of technical and management issues. This research investigates the use of BIM in the area of project planning and scheduling in the Australian construction industry. A mixed research method combining quantitative and qualitative approach is adopted. The research outcome shows that the general knowledge of BIM in the industry is not as extensive as it was perceived, but the technology is well accepted by the younger generation. It was discovered that the most common purposes of using BIM are for visualization and simulation, and BIM is also widely used for planning progress tracking. BIM is relatively rare to be used for management, especially in the construction stage. To further improve the use of BIM in project planning and scheduling, proposals have been made on enhancing software application interfaces, data exchanging and an efficient change management system.
The transfer and commercialization of university-developed medical imaging technology: opportunities and problems

The aging US population will increase the demand for cardiovascular care and thereby present opportunities for superconducting quantum interference device (SQUID) medical instruments. This paper discusses a university-based attempt to transfer and commercialize technology that potentially could eliminate the technical limitations of SQUID devices and allow their use in typical clinical environments. Based on the experiences thus far, lessons can be drawn for technology transfer of university developed medical technologies. First, universities need to re-examine the issue of the incentives to publish versus the incentives to protect intellectual property. Failure to properly align these incentives is likely to weaken or eliminate the potential for a strong intellectual property position. Second, although a number of technology-transfer strategies are potentially available to universities, three factors are critical in making this selection: (1) the strength of proprietary position; (2) the stage of development; and (3) the breadth of potential applications for the technology. Moreover, university technology-transfer offices need to take a businesslike approach in identifying appropriate technology-transfer strategies that match the technology, the marketplace, and commercialization potential. For universities seeking to commercialize medical technologies it is critical to expand collaborations with medical professionals to validate the clinical application of the technology. Finally, partnerships with medical device companies should be pursued to gain experience in product development.
Determination of parameters of some materials for millimeter waves using multifrequency measuring of reflection characteristics

One of problems of applied radiophysics is the necessity of measuring (checking) of parameters of layered structures by non-contact methods. The developed investigations have shown an opportunity of solution of the given problem on the basis of radiowave multifrequency measuring of reflection from the explored structures. The approach to determination of parameters of some industrial materials and liquids using multifrequency measurement at millimeter wave frequencies have been considered.
Influencing Factors of Institutional Investors Shareholding Stability

The premise for institutional investors to participate in firm innovation governance and promote firm innovation’s positive role is that institutional investors have specific decision-making power and are willing to participate in firm innovation governance. Therefore, the influencing factors of institutional investment shareholding stability are an important issue. This study investigates the impact of business connection, risk preference, policy factors, market factors, and firm factors on institutional investors’ shareholding stability using regressional analysis based on the samples of Chinese A-share listed firms from 2014 to 2017. The main findings show that institutional investors with higher business connections, risk preferences, and performance ranking intensity have poor shareholding stability. The reform has significant investment constraints on non-risk preference institutional investors but has insufficient investment constraints on risk preference institutional investors. The substitution and interaction between firm factors and the natural endowment of institutional investors occur alternately. This study’s results provide important policy implications to strengthen related business supervision between institutional investors and shareholding firms. The policy implications include relaxing the investment proportion restriction and establishing a market-oriented performance ranking and institutional investors’ evaluation mechanism.
A new species of Homonota (Squamata: Gekkota: Phyllodactylidae) from Paraguay

The 12 recognized species of the genus Homonota are geographically restricted to central and southern South America in Argentina, Brazil, Uruguay, Bolivia, and Paraguay. The phylogenetic relationships within the genus are well known where three groups are identified, each of them containing four species: the whitii group (Homonota darwinii, H. williamsii, H. whitii, and H. andicola), the borellii group (H. borellii, H. taragui, H. rupicola, and H. uruguayensis) and the horrida group (H. horrida, H. underwoodi, H. septentrionalis, and H. marthae). During fieldwork in Paraguay, we found a specimen of Homonota with unique morphological and geographical traits. Thus, we performed a comparative morphological analysis against specimens housed in different Paraguayan collections. Additionally, we performed a DNA analysis of our specimen to assess its relationships within the genus. Results suggest that this specimen represents a new species of the Homonota horrida group based on molecular and morphological evidence. The new species is characterized by a robust body, 10 longitudinal rows of strongly keeled scales separated by one or two granular scales, square-shaped mental scales, small postmental scales, one or two rows of rectangular scales in the upper eye scales, rostral scale divided, edge of auditory meatus serrated posteriorly, and black and brown background coloration with one white vertebral line and seven white transverse bands. The new species is restricted to Paraguarí Department, characterized by herbaceous grasslands with rocky outcrops.

The intersegmental motion of cervical spine with the in vivo measurement and a rigid body model

The functional analysis of the cervical spine permits the localisation as well as the classification of its pathologies, however current investigations remain difficult and very invasive. The purpose of this study is to determine the in vivo intersegmental motion and the loading condition of the cervical spine, creating a potential to investigate and diagnose pathologies using already existing classical clinical data. We propose a new approach that merges two types of data: The ‘dynamic’ X-ray images and the continuous motions of the whole cervical spine obtained with a tracking motion system. From these data, a rigid body model with imposed-displacement of cervical spine has been computed with MSC.ADAMS software. The kinematical and kinetic parameters of each functional spinal unit (FSU) were finally deduced from this model.
Modelling the Dimensions of a Competitive Intelligence - Based Corporate Culture Using the Digital Memory BRAIN 7

In the context of a dynamic business environment, leading software companies are focusing their strategies on a market-driven approach, exploiting the opportunities provided by competitive intelligence mechanisms, in order to continuously monitor the competitive landscape. Being aware of the lack of cultural patterns aligned to competitive intelligence issues from software industry, we intend to further explain the design of specific dimensions related to a competitive intelligence (CI) based organizational cultural pattern, which is customized for software companies. Our paper highlights the creative task of conceiving several dimensions of analysis which characterize the cultural aspects from the organizational life of software companies; by interpreting the information resulted during the open discussions with IT experts from Belgium software industry and taking into consideration the evidence that every organization involved in software development has different goals and requirements for a CI based culture, we propose four dimensions of analysis: expert-coder versus utility developer, competing on talents versus competing on technology, creative impulses versus procedure compliance and shared CI data versus classified CI data. The ideas launched during the interviews were interconnected in a digital map provided by the software “The Brain7”. We identify areas for further research by crossing the most relevant dimensions of analysis and outline the opportunities for the integration of CI within the corporate culture.
Domestic Terrorism and Sovereign Bond Ratings in the Developing World

ABSTRACT Since the 1990s, credit rating agencies have played a prominent financial role in developing countries, rating their sovereign bonds and determining capital costs. Over much the same years, domestic terrorism has expanded, increasing market disruptions in countries. Despite the heightened costs related to rebel attacks, few studies investigate the impact of domestic terrorism on bond ratings. Using a sample of seventy-one developing countries between 1996 and 2018, we find that domestic terrorist incidents result in sovereign bond downgrades for countries that receive ratings. Further, when we disaggregate terrorist events by target type, we observe that attacks directed at the government, military and police, business, non-governmental organizations, and private citizens/property have a larger effect than other terrorist incidents. We argue that specific domestic terrorist attacks increase economic instability, leading to capital flight, and a shifting of resources from productive economic sectors to counterterrorism. The resulting economic changes weaken a country’s economy and increase debt nonpayment risk.
