A Trajectory-Driven 3D Channel Model for Human Activity Recognition
2021
This paper concerns the design, analysis, and simulation of a 3D non-stationary channel model fed with inertial measurement unit (IMU) data. The work in this paper provides a framework for simulating the micro-Doppler signatures of indoor channels for human activity recognition by using radiofrequency-based sensing technologies. The major human body segments, such as wrists, ankles, torso, and head, are modelled as a cluster of moving point scatterers. We provide expressions for the time variant (TV) speed and TV angles of motion based on 3D trajectories of the moving person. Moreover, we present mathematical expressions for the TV Doppler shifts and TV path gains associated with each movin…
Ideal Chaotic Pattern Recognition is achievable: The Ideal-M-AdNN - its design and properties
2013
Published version of a chapter in the book: Transactions on Computational Collective Intelligence XI. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-41776-4_2 This paper deals with the relatively new field of designing a Chaotic Pattern Recognition (PR) system. The benchmark of such a system is the following: First of all, one must be able to train the system with a set of “training” patterns. Subsequently, as long as there is no testing pattern, the system must be chaotic. However, if the system is, thereafter, presented with an unknown testing pattern, the behavior must ideally be as follows. If the testing pattern is not one of the trained patterns, the system …
Changes of species specific cuticular hydrocarbon profiles in the cockroaches Nauphoeta cinerea and Leucophaea maderae reared in heterospecific groups
1997
0013-8703 (Print) 1570-7458 (Online); The cuticular hydrocarbon profiles of the cockroaches Nauphoeta cinerea and Leucophaea maderae are species-specific when maintained in homospecific rearings. When individuals were reared in mixed species colonies, they initially remained in homospecific groups under different shelters. However, after 14 days they formed one heterospecific group with cuticular profiles showing characteristics of both species. When individuals were returned in monospecific rearings, their cuticular hydrocarbon profiles returned to species-specific ones within 3 weeks.
Discrimination of nerve gases mimics and other organophosphorous derivatives in gas phase using a colorimetric probe array.
2012
A colorimetric array for the chromogenic discrimination of organophosphorous derivatives in gas phase has been developed. The array allows us to classify the nerve agent simulants DFP, DCP and DCNP.
Energy landscapes of ligand-receptor couples probed by dynamic force spectroscopy.
2013
Playing a dominant role in many biochemical processes are the dynamic properties of molecular linkages; examples include cell adhesion, enzyme-catalyzed reactions, and molecular recognition by antibodies. Dynamic force spectroscopy, namely separating molecular bonds under external force ramps has rapidly become a powerful tool to study the rugged energy landscape of noncovalent ligand-receptor bonds. The picture shows a surface and tip-bound pair being pulled apart and the derived potential energy diagram.
3,3′-Disubstitued 2,2′-Bipyridines as Carboxylate Receptors: Conformational Regulation of the Bipyridine Moiety
2008
Two bipyridine derivatives were synthesized and characterized, and their ability to act as sensors for carboxylates was evaluated by UV/Vis and fluorescence studies. The influence of the substituents of the thiourea groups on the stoichiometry of the resulting dicarboxylate complexes was established. Conformational changes in the bipyridine moiety under different conditions were evaluated.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
Fingerprints from fingerprints
2003
Besides ‘‘classical’’ biological materials such as blood and sperm, epithelial cells from latent fingerprints are targeted in forensic sciences. In addition to studies using latent fingerprints applied to beer glasses [1], T-shirts left on crime scenes [2] and various other objects [3], we report the detection of STR profiles from latent fingerprints deposited on ordinary sheets of paper. In contrast to the relatively high number of epithelial cells from saliva or from excessively pressured fingerprints during strangulation [4,5], the experiments with latent fingerprints are expected to generate only a very small number of epithelial cells. Moreover, cells remaining on objects touched only …
Evaluation of olfactory intensity : comparative study of two methods
2004
Two experimental procedures recommended for the evaluation of the psychophysical characteristics of odorous compounds, olfactory matching with the 1-butanol scale and cross-modality matching with the finger span are compared. The intensity of ethyl butyrate and guaiacol solutions presented at four different concentration levels was evaluated by a panel of sixteen subjects over five repetitions using the two methods. Each stimulus was delivered to the subject from a Teflon bag through a nose-shaped glass sniffing port. The discrimination ability, repeatability, panel homogeneity and within-subject variability of the methods were assessed. Results indicate that with both methods, subjects wer…
The e-ASTROGAM gamma-ray space observatory for the multimessenger astronomy of the 2030s
2018
e-ASTROGAM is a concept for a breakthrough observatory space mission carrying a gamma-ray telescope dedicated to the study of the non-thermal Universe in the photon energy range from 0.15 MeV to 3 GeV. The lower energy limit can be pushed down to energies as low as 30 keV for gamma-ray burst detection with the calorimeter. The mission is based on an advanced space-proven detector technology, with unprecedented sensitivity, angular and energy resolution, combined with remarkable polarimetric capability. Thanks to its performance in the MeV-GeV domain, substantially improving its predecessors, e-ASTROGAM will open a new window on the non-thermal Universe, making pioneering observations of the…
Triplet exciplexes as energy transfer photosensitisers
2006
Experimental evidence is provided for the occurrence of triplet–triplet energy transfer from benzoylthiophene–indole exciplexes to naphthalenes with a remarkable stereodifferentiation; chiral recognition is also observed in the decay of the generated naphthalene triplets.
