Abstract:
Methods and apparatus are described for monocular 3D human pose estimation and tracking, which are able to recover poses of people in realistic street conditions captured using a monocular, potentially moving camera. Embodiments of the present invention provide a three-stage process involving estimating (10, 60, 110) a 3D pose of each of the multiple objects using an output of 2D tracking-by detection (50) and 2D viewpoint estimation (46). The present invention provides a sound Bayesian formulation to address the above problems. The present invention can provide articulated 3D tracking in realistic street conditions. The present invention provides methods and apparatus for people detection and 2D pose estimation combined with a dynamic motion prior. The present invention provides not only 2D pose estimation for people in side views, it goes beyond this by estimating poses in 3D from multiple viewpoints. The estimation of poses is done in monocular images, and does not require stereo images. Also the present invention does not require detection of characteristic poses of people.
Abstract:
The invention relates to a circuit arrangement and a method for determining the rotor position when the rotor rotates slowly or is at a standstill. According to the invention, an RF signal is fed at the neutral point (zero component), and the rotor position is determined using the distribution of the RF signal in the coils (non-zero component).
Abstract:
The invention relates to oligo-tetracenes of formula (I) which are either unsubstituted or carry one or several substituents (R and R'), which are selected from the group which consists of halogen, CN, alkyl- or alkoxy radicals having 1 - 18 carbon atoms, aryl radicals having up to 12 carbon atoms which can also contain one or several heteroatoms and/or fluorinated or perfluorinated alkyl- or alkoxy radicals having 1 - 18 carbon atoms, wherein n is a whole number between 1 - 20, preferably 1 - 6, more preferably 1 or 2 and X represents an alklyene group having 1 6 carbon atoms, a hydrocarbon chain having one or several conjugated dual compounds, an aryl group or a system consisting of one or several condensed aromatic rings, for a single compound. In the inventive oligotetracenes, one or several of the six-atomic, condensed, aromatic rings can be replaced by a five-atomic ring which can contain a heteroatom. The invention also relates to a method for producing the known oligo-tetracenes and to the used thereof as a semi-conductor in organic field effect transistors (OFET), organic light-emitting diodes (OLEDs), sensors and organic solar cells.
Abstract:
The present invention relates to compounds having a high affinity for the Abeta protein, alpha-synuclein or for Tau-PHF aggregates, which are suitable as preferably fluorescent probes for the in-vivo diagnosis of neurodegenerative disorders, such as Alzheimer's disease and Parkinson's disease. The compounds are distinguished by suitable physiochemical properties (excitation wavelength, emission wavelength, Stokes shift, extinction) and also high affinity and selectivity for the target proteins.
Abstract:
A rotor blade is provided, in particular for wind power installations, having means for variation of the blade camber wherein the blade camber is varied by means of elements which are passively coupled to one another, that is to say without any external energy supply, apart from the energy contained in the air flowing around the rotor blade. For this purpose, one of the elements is in each case arranged on the leading edge and trailing edge of the profile of the rotor blade. The coupling of the elements, the stiffness of the profile and the level of the damping are in this case designed to be variable.
Abstract:
The invention relates to a method for monitoring a flow measurement for fluids. According to said method, a first measured variable, which is at least indirectly dependent on the fluid flow, such as the active pressure of fluid flow current and a second measured variable, which is at least indirectly dependent on the fluid flow and differs from the first measured variable, such as the eddy dissipation frequency against an interference body that is situated in the flow current, are simultaneously detected and/or calculated. The first and second measured variable are detected and/or calculated on the basis of an identical physical basic measuring principle and said first and second measured variable are compared.
Abstract:
The invention relates to a method for the electroless deposition of metals or metal oxides, wherein particle formation is prevented and smooth layers are formed. With this, layer thicknesses of 1 nm to 500 nm are achieved at temperatures between 0 and 100ºC. A composition of a plurality of layers is possible. The layers can be shaped by means of templates or printing, for example ink jet printing technique and screen printing.
Abstract:
The invention relates to a method for production of a supported oxidation catalyst with polyaniline or a polyaniline derivative as support and a catalytically active species, obtained from a compound made from a metal of group 8 to 11 of the periodic table of the elements. The invention further relates to the supported catalyst obtained by said method and a method for oxidation of carbon monoxide using said catalyst. The invention also relates to a fuel cell provided with said supported catalyst in addition to the actual fuel cell catalyst in order to purify in other words to remove carbon monoxide from the applied gases.
Abstract:
Disclosed is a Gunn diode (1). The top face and the bottom face of the active layer (2) of said Gunn diode (1) border an adjacent contact layer (4) which is more heavily doped than the active layer (2) and is made of the same material. In order to keep the contact resistance in the Gunn diode (1) particularly low, the external region (12) of at least one of the contact layers (4) is formed by an external contact layer (14) that is made of the same material and is even more heavily doped than the respective contact layer (4).
Abstract:
The invention relates to a method for the oxidation of a secondary hydroxy group of an organic compound to a keto group in the presence of at least one primary hydroxy group of said organic compound, especially for producing dihydroxyacetone (DHA) from glycerin. According to said method, the organic compound, particularly the glycerin, is reacted with oxygen in the presence of a supported metal catalyst, especially a multi-metal catalyst, comprising gold and platinum and other optional metals catalyzing oxidation of said organic compound, particularly glycerin, in an alkaline aqueous system so as to form an organic compound containing a keto group and at least one primary hydroxy group, especially of dihydroxyacetone. Preferably, the supported oxidation catalysts used in said method are obtained by carrying out the following steps: a) at least one metal salt and/or at least one acid of a metal which can catalytically oxidize hydroxyl groups to aldehyde groups or keto groups is reduced using at least one reducing stabilizer according to the Sol method in an alkaline aqueous system; b) a supporting material is contacted with the alkaline aqueous system and supports of the supporting material; c) the solid moiety is separated from the liquid portion; d) the separated solid moiety is washed; and e) the washed solid moiety is tempered. The invention further relates to the supported oxidation catalysts obtained according to the disclosed method.
