Modeling of ballistic nanoscale metal-oxide-semiconductor field effect transistors

We present a code for the quantum simulation of ballistic metal-oxide-semiconductor field effect transistors (MOSFETs) in two dimensions, which has been applied to the simulation of a so-called “well-tempered” MOSFET with channel length of 25 nm. Electron confinement at the Si/SiO2 interface and effective mass anisotropy are properly taken into account. In the assumption of negligible phonon scattering in nanoscale devices, transport is assumed to be purely ballistic. We show that our code can provide the relevant direct-current characteristics of the device by running on a simple high-end personal computer, and can be a useful tool for the extraction of physics-based compact models of nanoscale MOSFETs.
Characterization and identification of ascorbyl methylsilanol pectinate for cosmetic formulations application

The ascorbyl methylsilanol pectinate (AMP) presents the same functional properties of ascorbic acid (AA). Besides antioxidant and depigmentant activity, the AMP presents silanol in its chemical structure. The aim of this work was to characterize and indentify the AMP alone and in cosmetic formulations. The following techniques were employed: Fourier Transform Infrared Spectrophotometry, particle size distributions, in vitro antioxidant activity with 2.2-diphenyl-1-picrylhydrazyl (DPPH) and Oxigen Radical Absorbance Capacity Assay and High Performace Liquid Chromatography (HPLC) (developed and validated method) for the active ingredient; Microscopy, HPLC and Normal Stability Assay (NSA) for the emulsions. Particle size distributions results showed that the average size of AMP was 1.0 µm and polydispersity index was 0.1. In DPPH assay AA and AMP were statistically the same. The value of ORAC obtained for AMP was 0.74 and for AA in the literature was 0.95. In the NSA the formulations were stable in conditions of 5.0 and 45.0 ± 2.0 oC for 90 days. Adequate stability at ambient temperature out of reach of light was also observed. Thus, this works presented an acceptable method for quantification of AMP alone and in cosmetic formulations. AMP was an adequate choice for the incorporation in emulsions with antioxidant efficacy.
On Third-Order Bronze Fibonacci Numbers

In this study, we firstly obtain De Moivre-type identities for the second-order Bronze Fibonacci sequences. Next, we construct and define the third-order Bronze Fibonacci, third-order Bronze Lucas and modified third-order Bronze Fibonacci sequences. Then, we define the generalized third-order Bronze Fibonacci sequence and calculate the De Moivre-type identities for these sequences. Moreover, we find the generating functions, Binet’s formulas, Cassini’s identities and matrix representations of these sequences and examine some interesting identities related to the third-order Bronze Fibonacci sequences. Finally, we present an encryption and decryption application that uses our obtained results and we present an illustrative example.
Navier-Stokes predictions of the NREL phase VI rotor in the NASA Ames 80-by-120 wind tunnel

The application of an incompressible Reynolds Averaged Navier-Stokes solver to cases from the NREL/NASA Ames wind tunnel test is described. Six cases of the NREL PHASE-VI rotor in the upwind configuration under zero yaw and zero degrees tip pitch are computed. Favorable comparison of the computed results with measurements in the form of shaft torque, root moments, spanwise force distributions, and pressure distributions are shown. The good agreement documents the feasibility of 3D CFD computations in connection with prediction of the performance of new rotors. Additionally it is shown how CFD computations can be used to determine the three dimensional effects in rotor flows. © 2002 ASME
A Humanoid Robot’s Effortful Adaptation Boosts Partners’ Commitment to an Interactive Teaching Task

We tested the hypothesis that, if a robot apparently invests effort in teaching a new skill to a human participant, the human participant will reciprocate by investing more effort in teaching the robot a new skill, too. To this end, we devised a scenario in which the iCub and a human participant alternated in teaching each other new skills. In the Adaptive condition of the robot teaching phase, the iCub slowed down its movements when repeating a demonstration for the human learner, whereas in the Unadaptive condition it sped the movements up when repeating the demonstration. In a subsequent participant teaching phase, human participants were asked to give the iCub a demonstration, and then to repeat it if the iCub had not understood. We predicted that in the Adaptive condition, participants would reciprocate the iCub’s adaptivity by investing more effort to slow down their movements and to increase segmentation when repeating their demonstration. The results showed that this was true when participants experienced the Adaptive condition after the Unadaptive condition and not when the order was inverted, indicating that participants were particularly sensitive to the changes in the iCub’s level of commitment over the course of the experiment.
FAST DATA: A Fair, Secure, and Trusted Decentralized IIoT Data Marketplace Enabled by Blockchain

As the world calls it, data is the new oil. With vast installments of Industrial Internet of Things (IIoT) infrastructure, data is produced at a rate like never before. Similarly, artificial intelligence (AI) and machine learning (ML) solutions are getting integrated to numerous services, making them “smarter. ” However, the data remain fragmented in individual organizational silos inhibiting data value extraction to its full potential. Digital marketplaces are emerging to allow data owners to monetize these data. Yet concerns, such as privacy, security, and unfair payment settlement deter adoption of such platforms. In addition, the state-of-the-art platforms are under the control of large multinational corporations with no transparency between the buyer and seller in terms of payment details, listing, data discovery, and storage. In this work, a novel decentralized platform of a digital data marketplace for IoT data has been proposed. The platform leverages a decentralized data streaming network to host IoT data in a reliable and fault-tolerant manner. The platform ensures fair trading, data storage, and delivery in a privacy-preserving manner and trust metric calculation for actors in the network. In order to study the feasibility of the proposed platform, an opensource library is developed using Hyperledger Fabric and data network layer built on VerneMQ, the library is deployed on a real-time Google cloud platform. The library is tested and results are analyzed for throughput, overheads, and scalability.
Inter-influence of Temperature-time-reflectivity in the Coal Metamorphism Thermodynamics Equation (CMTE)

The influence and control of time and temperature on coalification are comprehensive. In order to quantitatively analyze the thermal kinetics of coal metamorphosis process by temperature and time, the qualitative analysis of coal metamorphosis thermodynamic equation (CMTE) based on Wu Chonglong was further verified from the mathematical point of view. Wu Chong Long's Coal Metamorphism Thermodynamics Equation (CMTE) is a ternary equation containing coal forming period or metamorphic age (time), metamorphic temperature (temperature) and metamorphic degree (reflectivity). The temperature calculated by fixing time and reflectivity is the lowest theoretical metamorphic temperature. The reflectivity calculated by fixing time and temperature is the maximum theoretical metamorphic degree. The “time-temperature ratio” is defined as the equivalent of extending million years to increasing 1°C temperature regarding coal metamorphism. This ratio is used to compare the impact of extending time or increasing temperature on improving the metamorphic degree and its significance. The results showed that in the same coal forming period, the ratio is decreased with the reflectivity increasing; at the same reflectivity, the ratio decreased with younger coal forming period. At Ro=6.1%, the calculated ratio is 3.67, which means, at Ro=6.1%, increasing 1°C is equaled extending 3.67 million.
New Betweenness Centrality Node Attack Strategies for Real-World Complex Weighted Networks

In this work, we introduce a new node attack strategy removing nodes with the highest conditional weighted betweenness centrality (CondWBet), which combines the weighted structure of the network and the node’s conditional betweenness. We compare its efficacy with well-known attack strategies from literature over five real-world complex weighted networks. We use the network weighted efficiency (WEFF) like a measure encompassing the weighted structure of the network, in addition to the commonly used binary-topological measure, i.e., the largest connected cluster (LCC). We find that if the measure is WEFF, the CondWBet strategy is the best to decrease WEFF in 3 out of 5 cases. Further, CondWBet is the most effective strategy to reduce WEFF at the beginning of the removal process, whereas the Strength that removes nodes with the highest sum of the link weights first shows the highest efficacy in the final phase of the removal process when the network is broken into many small clusters. These last outcomes would suggest that a better attacking in weighted networks strategy could be a combination of the CondWBet and Strength strategies.

Transient performance of a short-stroke linear solenoid actuator

A computational and experimental investigation of the transient performance of a solenoid actuator, with a stroke of 0.3 mm and a closure time of approximately 1.4 ms, is described. A coupled electric-circuit/transient finite element model of the actuation system is also described, with particular reference to the magnetic material characterisation, the mesh discretisation and the choice of time-step. The predicted transient performance is compared with measurements and predictions from a magneto-static finite element based simulation to highlight the influence of induced eddy-currents and magnetic hysteresis.
Accurate modeling and parameter extraction for 6H-SiC Schottky barrier diodes (SBDs) with nearly ideal breakdown voltage

We have fabricated Ni Schottky rectifiers on 2.7/spl times/ 10/sup 16/ cm/sup -3/ n-type 6H-SiC epilayer using an effective edge termination based on an oxide ramp profile around the Schottky contact. Several anneals of the Schottky contacts were experimented. In particular the diodes annealed at 900/spl deg/C showed excellent reverse characteristics with a nearly ideal breakdown at about 800 V. Forward characteristics follow the thermionic emission theory with the ideality factor close to one at low biases. An accurate analytical model and complete parameter extraction of the forward characteristics of the Ni/6H-SiC Schottky barrier diodes (SBDs) for low and high-level current densities are presented. The model takes into account the high-level injection effects and the current dependence of the series resistance. Direct extraction of the SBD parameters is carried out. A very good agreement between the simulated forward curves using extracted parameters and measured data up to 500 A/cm/sup 2/ is obtained.

Testing Socio-Economic Demographic Variables on building energy consumption scenarios at the urban scale in Italy

In order to meet EU 2020 energy efficiency aggressive goals, there is a need to scale up the achievement of real energy consumption savings of current high performing building to the urban level. However, current low-energy, zero carbon, and net zero energy buildings are not performing as designed. Within the building sector industry there is an increasing concern about the mismatch between expected and actual performance, typically addressed as the ‘credibility gap'. The reasons for this discrepancy vary, but are mostly rooted in oversimplifying or ignoring occupant behavior in the building operation process. In this view, the presented study is testing the magnitude of socioeconomic demographic variables on building energy consumption energy scenarios at the urban scale. Measured thermal energy consumption data for a block of building in Torino, Italy are coupled with Geographical System Information (GIS) public census socio-economic data related to building occupants and analyzed through data mining techniques. Hence, energy model scenarios will be drawn to represent the impact of different building occupant profiles over mid-long term building energy consumption at the urban scale. Interpretation of the energy scenarios may allow energy designers and modelers, building operator and manager to develop energy efficiency measures and standards taking into account the leverage of socio-economic factors related to building occupants. Results may also support energy and urban planners to the release of energy policies and the development of robust energy urban planning tools aiming to bridge the "credibility gap" of targeted energy efficiency in building
A power efficient 2Gb/s transceiver in 90nm CMOS for 10mm On-Chip interconnect

Abstract—Global on-chip data communication is becoming a concern as the gap between transistor speed and interconnect bandwidth increases with CMOS process scaling. In this paper a low-swing transceiver for 10mm long 0. 54μm wide on-chip interconnect is presented, which achieves a similar data rate as previous designs (a few Gb/s), but at much lower power than recently published work. Both low static power and low dynamic power (low energy per bit) is aimed for. A capacitive pre-emphasis transmitter lowers the voltage swing and increases the bandwidth using a simple inverter based transceiver and capacitive coupling to the interconnect. The receiver uses Decision Feedback Equalization with a power-efficient continuous-time feedback filter. A low power latch-type voltage sense amplifier is used. The transceiver, fabricated in a 1.2V 90nm CMOS process, achieves 2Gb/s. It consumes only 0.28pJ/b, which is 7 times lower than earlier work.
Monte Carlo Simulation of Household Travel Survey Data for Sydney, Australia: Bayesian Updating Using Different Local Sample Sizes

Interest is increasing in the potential to simulate household travel survey data as an alternative to collecting large sample household travel surveys or as a means to augment sample sizes. In earlier research on simulating such data, it was shown that it was possible to reproduce, within reasonable bounds of accuracy, an actual household travel survey. It has also been found that the procedure for updating the distributions of the simulated variables, by using Bayesian updating with subjective priors, can provide significant improvement in the accuracy with which an actual household travel survey can be simulated. In work performed to date, the optimal size for the update sample to be used in the Bayesian updating has not been determined. Rather, earlier work used a sample of approximately 500 households, primarily because of convenience and cost. In further research that compared different sample sizes for the local update data, it was found that a reasonable updating could be obtained from a sample as small as 300 households, chosen through a stratified sampling procedure, and that results improved substantially when the update sample was increased to 500. However, an increase in the sample to 750 did not produce much improvement, which suggested that samples of this size and larger may not be economically justified. The research suggests that there may be room for a more targeted sampling procedure, which might allow smaller samples to be more cost-effective.
A Continuum Model for Water Transport in the Ionomer-Phase of Catalyst Coated Membranes for PEMFCs

We study the problem of water transport in the ionomer-phase of catalyst coated membranes (CCMs) for proton exchange membrane fuel cells (PEMFCs), where microscopic-scale phenomena at the distributed interfaces between structural components control the water management. Existing models for water transport in CCMs describe the transport in systems which consist exclusively of an ionomer-phase. Interfacial water fluxes across distributed interfaces representing various mechanisms of water transfer between ionomer and catalyst layer pores are not captured properly in these models. Here we develop a continuum model for water transport in CCMs using the method of volume averaging. Water is exchanged between ionomer and the catalyst layer pores by electro-osmotic discharge (EOD) through the three-phase boundary (TPB) regions and by sorption and desorption across the ionomer-pore interfaces. While the former mechanism does not affect directly the water content in the ionomer-phase, it represents an effective mechanism for water transfer during fuel cell operation and controls directly the water saturation in the catalyst pores.
Optimal Energy and Cleaning Management in Heat Exchanger Networks Under Fouling

This paper addresses the problem of cyclic cleaning and energy scheduling in special classes of heat exchanger networks (HENs). A salient characteristic of this problem is that the performance of each heat exchanger decreases with time and can then be restored to its initial state by performing cleaning operations. Due to the cyclic nature of the schedule, some operations may span successive cycles (wrap-around) which is taken into account in the mathematical model. A tight mixed integer linear programming (MILP) model is presented which is solved to global optimality. A detailed objective function is used to account for cleaning cost and energy requirements. The formulations can model serial and parallel HENs, as well as network arrangements arising from the combination of these basic cases. The optimization algorithm determines simultaneously: (i) the number of cleaning operations required along with their corresponding timings and (ii) the optimal utility utilization profile over time. A complex heat exchanger network example is presented to illustrate the applicability of the proposed model.
Russian language teachers’ professional agency against the backdrop of the New National Teaching Quality Standards in China: an ecological perspective

ABSTRACT With the ‘New National Teaching Quality Standards’ and its supplement – the ‘Guide for the Russian Majors Education’ as language education policies, this paper argues that these policies have constructed an ecological environment for Russian language teachers’ (RLTs) agency in China. The interpretive policy analysis, interviews and classroom observations of four RLTs help explore which environmental factors (the macro-system, exo-system, meso system and micro-system) impact their agency from an ecological perspective, and which factors are ignored by RLTs. The findings are: (1) (the ideology embodied in) these policies is (are) mandatory in terms of the vocabulary and text, and they set a macro (exo-) framework for and influence RLTs’ agency; (2) The meso system (universities) has the greatest impact on RLTs’ agency, which may access or deny the possibilities the macro-language policy may offer; (3) RLTs’ dispositions and the Russian language department constitute a potential micro-system, and the role of this sub-system in RLTs’ agency cannot be ignored. This study is of methodological, theoretical, and practical significance for research on the impact of language policy and planning (LPP) on the developmental environment for teachers of less-commonly-taught language in terms of LPP for the diversity of foreign language education.

To test the proposed monitoring functions, a microcomputer based system was implemented, processing the data on-line at 2.4 kHz sampling rate per phase. Signals with known disturbing effects were used to validate the algorithms. Results obtained from monitoring the network secondary voltages, are also presented to demonstrate the application feasibility of the proposed monitoring system.
