Wide tuning range cmos millimeter-wave vco using resistors-added mosfet varactor

This article presents a CMOS millimeter-wave voltage-controlled oscillator (VCO), which provides a wide tuning range using a resistors-added MOSFET varactor.Large resistors connected to the source and bulk allow a MOSFET varactor to lower minimum capacitance and to maintain maximum capacitance compared to a conventional MOSFET varactor. Thus, the total capacitance tuning range of the proposed varactor is expanded to ±46.1%, allowing a VCO with the new varactor to possess a frequency tuning range of 13.4% from 29.3 to 33.5 GHz. The measured phase noise is −97.8 dBc/Hz at a 1-MHz offset at the center frequency of 31.3 GHz. The VCO in a 0.18-μm standard CMOS process dissipates 12.6 mW from a 1.8-V supply voltage. © 2012 Wiley Periodicals, Inc.

Establishment of a transnational ESPON training  programme to stimulate interest to ESPON2013 knowledge

The ESPONTrain Project is aiming at making ESPON2013 knowledge operational in a coordinated and transnational way for practical use at regional and local level, and translating ESPON Europe-wide information and findings to the regional/local level. Specifically, the project is aiming at: •Stimulating a transnational educational and training ESPON activity facilitated by both an e-learning procedure and a networking promoted by ECPs. •Identifying efficient target groups within the national environments (both educational and policy making) so as to be multipliers of the diffusion of the ESPON philosophy, ideas, findings and results. •Disseminating knowledge already produced by the ESPON2013 Programme transforming it in comprehensible educational and training material, maintaining its scientific soundness.
Theory of optical transitions in conjugated polymers. I. Ideal systems

We describe a theory of linear optical transitions in conjugated polymers. The theory is based on three assumptions. The first is that the low-lying excited states of conjugated polymers are Frenkel excitons coupled to local normal modes, described by the Frenkel-Holstein model. Second, we assume that the relevant parameter regime is ℏω ≪ J, i.e., the adiabatic regime, and thus the Born-Oppenheimer factorization of the electronic and nuclear degrees of freedom is generally applicable. Finally, we assume that the Condon approximation is valid, i.e., the exciton-polaron wavefunction is essentially independent of the normal modes. Using these assumptions we derive an expression for an effective Huang-Rhys parameter for a chain (or chromophore) of N monomers, given by S(N) = S(1)/IPR, where S(1) is the Huang-Rhys parameter for an isolated monomer. IPR is the inverse participation ratio, defined by IPR = (∑(n)|Ψ(n)|(4))(-1), where Ψ(n) is the exciton center-of-mass wavefunction. Since the IPR is proportional to the spread of the exciton center-of-mass wavefunction, this is a key result, as it shows that S(N) decreases with chain length. As in molecules, in a polymer S(N) has two interpretations. First, ℏωS(N) is the relaxation energy of an excited state caused by its coupling to the normal modes. Second, S(N) appears in the definition of an effective Franck-Condon factor, F(0v)(N) = S(N)(v)exp ( - S(N))/v! for the vth vibronic manifold. We show that the 0 - 0 and 0 - 1 optical intensities are proportional to F00(N) and F01(N), respectively, and thus the ratio of the 0 - 1 to 0 - 0 absorption and emission intensities are proportional to S(N). These analytical results are checked by extensive DMRG calculations and found to be generally valid, particularly for emission. However, for large chain lengths higher-lying quasimomentum exciton states become degenerate with the lowest vibrational excitation of the lowest exciton state. When this happens there is mixing of the electronic and nuclear states and a partial breakdown of the Born-Oppenheimer approximation, meaning that the ratio of the 0 - 0 to 0 - 1 absorption intensities no longer increases as fast as the IPR. When ℏω/J = 0.1, a value applicable to phenyl-based polymers, the critical value of N is ~20 monomers.
A study of the relationships among environmental performance, environmental disclosure, and financial performance

Purpose The purpose of this paper is to study the relationships among environmental performance (EP), environmental disclosure (ED), and financial performance (FP) (three corporate constructs) using data from Newsweek’s green rankings. Design/methodology/approach Previous studies document mixed results about the relations among the three constructs. A firm’s overall management strategy may affect the three constructs simultaneously; therefore, the interrelationships among EP, ED, and FP were jointly examined. A simultaneous equations approach was used to test the hypothesis. Findings The three-stage least square (3SLS) estimation results show a negative relationship between EP and FP and a positive relationship between EP and ED, suggesting that financially successful firms are less likely good environmental performers but green firms are more likely to disclose their EP. Research limitations/implications Since the sample firms examined in this study are US large-size companies, the results found in this paper may not apply to small- and/or medium-size firms or to companies in other countries. Practical implications Three corporate constructs are jointly correlated with each one. A firm’s overall strategic plan on environmental engagement is likely reflected in how it engages in each of the constructs that affect costs and benefits. Sustainable efforts, in short term, may put firms at risk. Companies may need to take a long-term perspective when cutting costs is curtailed. Originality/value The research contributes to the ED and EP literature by using a 3SLS simultaneous equation method and analyzing a more recent and comprehensive multi-industry data. By controlling industry effect, the research investigates the interrelationships among three corporate constructs and finds interesting results. An interpretation and discussion are provided.
Comparative vibrational spectroscopic studies, HOMO–LUMO and NBO analysis of N-(phenyl)-2,2-dichloroacetamide, N-(2-chloro phenyl)-2,2-dichloroacetamide and N-(4-chloro phenyl)-2,2-dichloroacetamide based on density functional theory

Abstract The structure and the vibrational frequencies of the fundamental modes of the optimized geometry of N-(phenyl)-2,2-dichloroacetamide (NPA), N-(2-chloro phenyl)-2,2-dichloroacetamide (2CPA) and N-(4-chloro phenyl)-2,2-dichloroacetamide (4CPA) have been determined by DFT/B3LYP method. A detailed vibrational spectral analysis was carried out and the assignments of the observed bands have been proposed on the basis of potential energy distribution (PED). Molecular electrostatic potential (MEP) surface was plotted over the geometry to elucidate the reactivity of the molecule. NBO analysis has been performed in order to elucidate charge transfer or conjugative interaction, the intra-molecule rehybridization and delocalization of electron density within the molecule. The lowest singlet → singlet spin-allowed excited states were taken into account for the TD-DFT calculations in order to investigate the properties of electronic transition. HOMO–LUMO analysis has been done in order to determine the way the molecule interacts with other species. On the basis of vibrational analysis, the thermodynamic properties of the title compounds at different temperatures have been calculated, revealing the correlations between heat capacity ( C p,m ∘ ), entropy ( S m ∘ ), enthalpy ( H m ∘ ) and temperature. Other molecular properties such as ionization energy, electron affinity, chemical potential, global hardness and electrophilicity were also calculated.

Assistive devices for the visually impaired and other disabilities

In 2010, there were 285million blind and visually impaired people in the world (a 77% increase from 161million in 2002) and that is a number that is still growing. In line with the European Disability Strategy 2010 – 2020 and to provide a technological solution to help the visually blind increase their level of security and independence, Aticser has been developing a kit of small, assistive devices controlled by our visually impaired user-friendly mobile app to help them in their daily lives. Aticser has been working with influential blind associations throughout Europe to produce the T4F Basic Kit, but we hope to improve it according to the comments and suggestions given by individuals and the blind associations that have validated the Basic Kit to produce a new and improved 2.0 Kit based on a modular approach. During our product validation, 85% of users expressed willingness to pay saying they will buy our new T4F Kit when it is on the market. We already have agreements with over 10 companies in Europe, Canada, the US, India and China who will be distributors who sell our T4F Kits to the end user (blind and visually impaired people). 80% will be sold through the distributors, such as the Spanish organisation ONCE (which is the most common way for blind people to buy assistive devices) and 20% directly through our website. We have a large potential market at a worldwide level: 99 million users = 147.960 millions of €s. Our goal for the SME Instrument project is to add functionalities to our T4F Basic Kit and to add a couple of devices to make our T4F 2.0 Kit disruptive to the existing market which so far does not include a one-stop solution like ours. Our T4F 2.0 Kit will make daily tasks easier for blind and visually impaired people and in the future, we plan to develop our products for people with other disabilities (such as Parkinson’s disease) with the help of other disability associations: AMPANS and Via Libre.
Dynamic agile production robots that learn and optimise knowledge and operations

Agile Production crucially depends on the effectivity of intralogistics processes. Robots as components of these processes have the potential to be a game changer provided they are highly flexible, capable, cost- and energy-efficient, safe and able to operate in work environments shared with humans. However, the current state of the art falls short of providing these capabilities given the requirements for future production systems. Thus, DARKO sets out to realize a new generation of agile production robots that have energy-efficient elastic actuators to execute highly dynamic motions; are able to operate safely within unknown, changing environments; are easy (cost-efficient) to deploy; have predictive planning capabilities to decide for most efficient actions while limiting associated risks; and are aware of humans and their intentions to smoothly and intuitively interact with them. To maximise its impact, DARKO is aligned with use cases at the largest manufacturer of home appliances in Europe. It will demonstrate, in relevant scenarios, autonomous capabilities significantly beyond the current state of the art in dynamic manipulation (e.g., throwing of goods, picking and placing objects while in motion), perception, mapping, risk management, motion planning and human-robot interaction. Beyond its impact through improved capabilities in these areas, DARKO will provide answers to the questions where and how dynamic manipulation should be integrated as the most efficient solution in intralogistics. Since arm manipulators can, in principle, display super-human performance in terms of accuracy and repeatability, the value of integrating dynamic manipulation, e.g. throwing, into transport processes may well exceed current expectations. The DARKO consortium is uniquely placed to tackle this ambitious and challenging project. It brings together leading academic and corporate researchers, technology providers and end-users, with the required long-standing expertise.
In situ observation of solidification patterns in diffusive conditions

Abstract We present a review of recent in situ experimentation studies of solidification front patterns and microstructures in alloys. Front-tracking diagnostics and real-time observation methods using high-resolution optical or X-ray imaging devices currently apply to model transparent systems as well as metallic alloys in thin and bulk samples. On a theoretical basis that spans the physics of nonequilibrium pattern formation and materials science, in combination with time-resolved numerical simulations, conclusive results of both fundamental- and applied-science interest have been obtained on major problems relative to multiscale microstructure selection, morphological transitions, and crystallographic effects during single- and multi-phase solidification. We will mainly focus on the dynamics of cellular, dendritic, and eutectic growth patterns in diffusive-growth conditions, that is, in the absence of convection in the liquid. This can be achieved in (semi-)thin samples, or, for bulk solidification, in the reduced-gravity environment of orbiting facilities. A selection of emerging work on, e.g., faceted growth and adaptive control of solidification patterns will furthermore be reported. We conclude by pointing out open questions and new perspectives for future research.
Tutkijoiden yö

TY2020 is a nationally extensive project, aiming to foster visibility of multidisciplinary science and its results, as well as interaction and collaboration between the public and researchers in Finland. The ultimate aim is to enhance involvement and evidence-based impact of research in the society in order to improve our everyday life in a rapidly changing world. Grounded on successful earlier nation-wide NIGHT-collaborations in 2016-2019, this project brings together several universities, research institutes, research funding agencies, and expert organisations for science communication. It spans many facets of research and covers numerous individual researchers with diverse backgrounds and research topics. We will deliver a message of cutting edge research conducted in Finland and introduce the general public with the large number of researchers and the significant work they perform. We want to break stereotypes the general public may have on researchers. The programme for activities during the night will include content for everyone, from children to seniors. However, the specific aim is to promote research careers especially to high school and university students, and young people in general who are about to make their first real career choice. Our message is that high education is fun and could provide them with a secured future. Many Finnish universities and organisations have united for a widespread European Researchers’ Night and will simultaneously perform activities targeted for the general public around the country.
Resilience to early developmental adversity: can children's environment help them overcome the odds?

Socioeconomic inequalities in children’s neurodevelopment and mental health are observed from early onwards and widen over time. Moreover, children whose parents are immigrant, particularly if they belong to ethnic minority groups, may be especially vulnerable. Yet there are important inter-individual differences in development, implying the possibility of resilience. My project will examine the consequences of multiple forms of socioeconomic adversity in children’s family and broader social environment with regard to their neurodevelopment and mental health, testing the role of social supports as sources of resilience. Specifically, I will rely upon longitudinal data collected from the ELFE child cohort study, a nationally representative sample of 18 321 children born in France in 2011 and followed-up to age 10.5 years, which will be linked with longitudinal administrative and geographical information characterizing neighbourhoods of children’s school and residence, as well as healthcare use data. Potential resilience factors will include familial (e.g. relations between the child and his/her mother and father, grandparents’ involvement) and contextual social supports (e.g. childcare prior to school entry, neighborhood social capital). Lifecourse patterns of adversity and resilience at each level of analysis will be identified using statistical methods developed for high-dimensional data and their influence on children’s development will be ascertained applying methods that strengthen causal inference (e.g. propensity scores). The results will help clarify 1) the ways in which lifecourse patterns of exposure to adversity in the family and children’s broader social environment can influence neurodevelopment and mental health, particularly among children of immigrants; 2) familial and collective factors that can help children overcome the odds and should be promoted.
Building innovative green hydrogen systems in an isolated territory: a pilot for europe

BIG HIT will create a replicable hydrogen territory in Orkney (Scotland) by implementing a fully integrated model of hydrogen production, storage, transportation and utilisation for heat, power and mobility. BIG HIT will absorb curtailed energy from two wind turbines and tidal turbines on the islands of Eday and Shapinsay, and use 1.5MW of PEM electrolysis to convert it into ~50 t pa of hydrogen. This will be used to heat two local schools, and transported by sea to Kirkwall in 5 hydrogen trailers, where it will be used to fuel a 75kW fuel cell (which will provide heat and power to the harbour buildings, a marina and 3 ferries when docked), and a refuelling station for a fleet of 10 fuel cell vehicles. 

The project employs a novel structure to manage the hydrogen trading, and dissemination that includes a follower territory and associations of over 1640 isolated territories.
Simulation study of magnetic resonance imaging examination reservation processes for stroke patients

The timely imaging examinations are most important for stroke patients to have the further appropriate diagnosis and treatment. We have proposed a contract-based Magnetic Resonance Imaging (MRI) reservation process in [1] in order to reduce their waiting time for MRI examinations. Contracted time slots (CTS) are especially reserved for stroke patients. Regular time slots (RTS) assignment policy is to assign some “unlucky” patients to RTS by keeping CTS queue length below a certain threshold. We further propose a reservation process in [2] in order to reduce the waiting time of these “unlucky” patients by utilizing the virtual CTS queue. RTS assignment policy is used to reserve additional RTS instead of assigning specific patients directly to RTS. This paper proposes a new reservation process without the virtual CTS queue. All times slots including CTS and RTS are used on FIFO (First In First Out) order. Computational results show that the improved method can greatly reduce the maximal waiting time and the deviation of average waiting time.
Relation between temperature–pressure dependence of internal pressure and intermolecular interactions in ionic liquids – Comparison with molecular liquids

Abstract The effect of alkyl chain length in cation, temperature and pressure on internal pressure was discussed for aprotic ionic liquids characterized by different hydrogen bonding ability resulting from the structure of the cation (disubstituted imidazolium, trisubstituted imidazolium, pyrrolidinium), and from the structure of the anion (tricyanomethanide, thiocyanate, ethyl sulfate, diethyl phosphate, acetate, bis(trifluoromethylsulfonyl)imide). The internal pressure was calculated by means of the acoustic method from the speed of sound, density and isobaric heat capacity data. The obtained results are compared and analysed along with available literature data. The internal pressure of ionic liquids was compared also with those of alkanes, alkanols, esters and diols. The obtained results show that temperature and pressure dependence of internal pressure for ionic liquids reflects the hydrogen bond capability between cation and anion.

Stress concentration factors of negative large eccentricity tubular N-joints under axial compressive loading in vertical brace

Abstract Negative large eccentricity tubular N-joints sometimes are used in welded trusses and offshore structures under fatigue loading. It is imperative that researches should be done on fatigue behavior of negative large eccentricity tubular N-joints under fatigue loading, though static behavior of negative large eccentricity tubular N-joints has been researched. The stress concentration factors (SCFs) are the main parameters in the fatigue behavior analysis of negative large eccentricity tubular N-joints. Four negative large eccentricity tubular N-joints specimens were separately tested for calibration and verification of finite element analysis models by considering axial compression in vertical brace case. All experimental joints were simply hinge supported at one end of chord and inclined brace end. Elastic gradient strain distributions along the intersection of joints were measured. Strain concentration factors (SNCFs) at hot spots including saddle and crown points were computed taking advantage of an extrapolation approach. As eccentricity decreased, the position of maximum SCF moved from the saddle point to the crown point at the inclined brace and vertical brace intersection near the vertical brace or the inclined brace. The maximum SCF at the chord and inclined brace intersection near the chord or the inclined brace occurred on the crown point. For the FE analysis, solid elements and certain mesh size were used to model the N-joints. Effects of brace diameter to chord diameter ratio ( β ), chord diameter to thickness of chord ratio (2 γ ), brace wall thickness to chord wall thickness ratio ( τ ) and eccentricity ratio ( e ) on the SCFs distribution of the negative large eccentricity tubular N-joints were numerically investigated. SCF linearly increased with the increase of eccentricity ratio at the inclined brace and vertical brace intersection near inclined brace and at chord and inclined brace intersection near inclined brace. The effect of eccentricity ratio on SCF equations of small eccentricity tubular N-joints was not considered in current code. A series of parametric equations considering eccentricity ratio were proposed for calculating the SCFs of negative large eccentricity tubular N-joints based on 256 joints FEA models calculation result.
