Real-time smoothing of car-following data through sensor-fusion techniques

2011

Abstract Observation of vehicles kinematics is an important task for many applications in ITS (Intelligent Transportation Systems). It is at the base of both theoretical analyses and application developments, especially in case of positioning and tracing/tracking of vehicles, car-following analyses and models, navigation and other ATIS (Advanced Traveller Information Systems), ACC (Adaptive Cruise Control) systems, CAS and CWS (Collision Avoidance Systems and Collision Warning Systems) and other ADAS (Advanced Driving Assistance Systems). Modern technologies supply low-cost devices able to collect time series of kinematic and positioning data with medium to very high frequency. Even more da…

Reflectance Measurement Method Based on Sensor Fusion of Frame-Based Hyperspectral Imager and Time-of-Flight Depth Camera

2022

Hyperspectral imaging and distance data have previously been used in aerial, forestry, agricultural, and medical imaging applications. Extracting meaningful information from a combination of different imaging modalities is difficult, as the image sensor fusion requires knowing the optical properties of the sensors, selecting the right optics and finding the sensors’ mutual reference frame through calibration. In this research we demonstrate a method for fusing data from Fabry–Perot interferometer hyperspectral camera and a Kinect V2 time-of-flight depth sensing camera. We created an experimental application to demonstrate utilizing the depth augmented hyperspectral data to measu…

H1-antihistamines suppress wheal-and-flare reaction and skin blood perfusion measured by Laser Dopppler flowmetry: randomized, double-blind, placebo-controlled, crossover design study The aim of our study was to compare the influence of pre-treatment with H1-antihistamines (levocetirizine, desloratadine, clemastine, quifenadine, and sequifenadine) and a placebo on the histamine-induced weal and flare reaction, increase of skin blood perfusion and sedation. Thirty healthy volunteers were enrolled in the study. The study design was a prospective, randomised, double-blind, placebo-controlled, crossover, balanced clinical trial. Volunteers in randomised and double-blind order were treated with …

Maturation of Epidermal Langerhans Cells In Vitro Is Accompanied by Downregulation of 4F2 (CD98) as Determined by Differential Display

1998

Following short-term culture, Langerhans cells mature morphologically and functionally into potent immunostimulatory cells. As regulation of gene expression accompanies this maturation process, it is likely that differentially expressed genes are involved in the maturation events. Using the recently described method of differential display, we generated cDNA expression patterns starting with mRNA of murine epidermal Langerhans cells isolated either directly (fLC) or following 3 d cultivation (cLC). Five hundred putative differentially expressed cDNA fragments were recovered from the gel. For a part of the fragments differential expression was confirmed by dot blot and Southern hybridization…

Détermination du taux de salaire réel et analyse néoclassique

1997

L'ambition des Néoclassiques est d'établir une loi scientifique de la répartition qu’ils expliquent essentiellement de deux façons. La première explication est fondée sur la productivité marginale des facteurs déterminée à la production. La seconde est fondée sur l'échange qui détermine la rémunérationdes facteurs ou leur « prix » sur le marché. Or, ces deux déterminations ne sont pas compatibles. La théorie marginaliste écarte d'emblée une grande partie de la réalité économique représentée par les rendements croissants et constants. Elle limite encore son champ en supposant que sur une quantité fixe d’un facteur on peut employer n’importe quelle quantité de facteur variable, hypothèse néce…

Successful adaptation of immigrants to Finland : can cultural fusion work?

2017

Immigration numbers in Finland are growing, more than doubling in the past decade, with immigrants arriving from increasingly diverse regions of the world. An attempt should be made to understand what are the factors that lead immigrants to finding happiness, and to mitigate the apparent rise in assimilation and anti-immigrant attitude in Finland. Most of the interviewees (n=16; 7 females, 9 males) have embedded themselves in dispersed communities, with connections from the workplace, studies, or common interests (e.g., religion, hobbies) that rarely including their immediate neighbors. Several reported a comfort in their own uniqueness. Some pointed to the kindness of Finns as integral to …

Do humans dream of prophetic robots?

2020

Social robotics is a technology that, as its definition varies, encompasses conceptually diverse fields materializing in innovations from simple chatbots to sophisticated androids talking about the peaceful coexistence of humans and robots. The advances in social robotics have led to promising applications in education, work, entertainment, and even religion. Yet a measure of fear and confusion about the capabilities of contemporary and future robots exists, with one of the reasons being the presentation of some contemporary robots as being more advanced than they really are.

Spectroscopic studies of semiconducting single-walled carbon nanotubes

2010

The unique nature of optical properties of single-walled carbon nanotubes (SWCNT), together with their promising potential applications, have created enormous interest towards the photophysics of SWCNT. Many aspects of carbon nanotubes originate from the electronic structure of carbon honeycomb lattice and one-dimensionality. SWCNTs exist in various chiral structures and diameters, which the optical and electrical properties are dependent on. It has been discovered that SWCNT excited states are excitonic with strong Coulomb interaction between the electron and the hole. However, many features of excitons are not yet well defined, such as absorption cross-sections, fluorescence quantum yield…
