We present detailed continuous wave (cw) and transient photoinduced absorption (PA) measurements in thin films of a novel alternating polyfluorene copolymer, poly[2,7-(9,9-dioctyl-fluorene)-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3-benzo-thiadiazole)] (DiO-PFDTBT), and its blends with the soluble fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) in weight ratios of 1:0, 4:1 and 1:4.
To increase the pace of development and deployment of new services and applications in telecommunication networks, new service architectures have been proposed. Parlay/OSA is one of the proposals that has aroused most attention. By providing network functionality via Application Program Interfaces (APIs), Parlay/OSA facilitates creation of telecommunication services and applications for independen
The LUCS Haptic Hand I together with a set of haptic models is the first in a series of projects aimed at studying haptic perception for building several robotic hands together with cognitive computational models of the corresponding human neurophysiology. The haptic systems have been trained and tested with a set of objects consisting of balls and cubes, and the activation in the modules correspo
When an argon matrix containing hydrogen peroxide dimer is irradiated with 266 nm radiation from a YAG laser, water forms. Some of it is formed as monomer but the main part is formed as dimer. The photogenerated water dimer is formed together with an oxygen molecule in the cage of the parent hydrogen peroxide dimer and the dimer bands are shifted from their normal positions indicating that the cag
This study evaluated the early phase of development of a model for quality improvement of habilitation and rehabilitation project processes. The focus of the methodologic support in habilitation and rehabilitation model was on cooperation between practice contexts and science. Habermas' theory about communicative action was a theoretical frame of reference. Three project coordinators and ten proje
In this paper we consider a 1-warehouse, N-retailer inventory system where demand occurs at all locations. We introduce an inventory model which allows us to set different service levels for retailers and direct customer demand at the warehouse. For each retailer a critical level is defined, such that a retailer replenishment order is delivered from warehouse stock if and only if the stock level e
The theoretical background and research evidence supporting two alternative scenarios – worsening health and improving health at increasing life expectancy is analyzed. It is shown that the prevailing “longer life – worse health” theory is based on the logic that due to the reduced birth-rate and increased proportion of older citizens the process of population aging is taking place, leading to an
Neuropeptide Y is a sympathetic co-neurotransmitter released with noradrenaline upon sympathetic nerve stimulation. This study describes the ability of a synthetic inositol phosphate, alpha-trinositol(D-myo-inositol 1,2,6-triphosphate; PP 56) to antagonize vasoconstrictor responses to neuropeptide Y in-vitro as well as in-vivo. In human and guinea-pig isolated arteries alpha-trinositol potently (1
Earlier detailed studies of cnidarian planula larvae have revealed a simple nervous system but no eyes or identifiable light sensing structures. Here, we describe the planula of a box jellyfish, Tripedalia cystophora, and report that these larvae have an extremely simple organization with no nervous system at all. Their only advanced feature is the presence of 10-15 pigment-cup ocelli, evenly spac
Experiments were conducted to study the energy efficiency of the impulse unit in the pilot-scale research paper machine at the Swedish Pulp and Paper Research Institute (STFI) In Stockholm, Sweden. The paper produced was made of kraft softwood pulp with basis weights of 60-120 g/m(2). The roll surface temperature ranged from ambient temperature to 350 degreesC and the press loads were between 400-
In this article we analyze what has been achieved by the introduction of the euro in terms of macroeconomic convergence and leveling of competitive conditions among the EMU member countries. In particular, has the convergence in nominal exchange rates resulted in divergence in real exchange and interest rates? And how has Finland fared relative to the EMU members? The answer is that real exchange
We investigate the noise properties of a zero-dimensional InAs quantum dot (QD) embedded in a GaAs-AlAs-GaAs tunneling structure. We observe an approximately linear dependence of the Fano factor and the current as a function of bias voltage. Both effects can be linked to the scanning of the three-dimensional emitter density of states by the QD. At the current step the shape of the Fano factor is m
In this article, some of the possibilities and obstacles involved in attaining stable peace in the Baltic Sea region are analysed. By stable peace is understood a relationship in which military conflict resolution has become unthinkable regardless of how serious a prospective conflict may become. It is argued that stable peace does not presently exist in the region as a whole, but that instead the
The purpose of this paper is to provide a research outlook on the concept of decentralized freight intelligence, i.e. autonomous freight making localized routing decisions. A review of research literature on decentralized intelligence in freight transport serves as the foundation of the analysis. The analysis reveals a scarcity of scientific evidence to suggest a successful introduction of decentr
Weak economic growth is a contributing factor behind many banking crises. In this paper, we test whether banking crises cause long-term institutional change aimed at improving macroeconomic performance and thus indirectly reduce the risk of future crises. Our dataset consists of 22 developed and 34 developing countries covering the period from 1985 to 2009. The results show that banking crises cau
The major input signals entering the PID controller are: the setpoint, the process output, and measurable load disturbances. By feeding these signals through suitable filters, the properties of the feedback loop can be improved significantly. The goal of this paper is to provide a unified discussion about these filters. The paper treats set-point handling, feedforward from load disturbances, TITO
