Microscope de fluorescence par réflexion totale interneLe microscope de fluorescence par réflexion totale interne (TIRFM, total internal reflection fluorescence microscopy), ou microscope à onde évanescente, est un type particulier de microscope optique à fluorescence permettant d'examiner une tranche très fine d'un échantillon (moins de 200 nm d'épaisseur), grâce à un mode d'illumination particulier : la réflexion totale interne.
Activity recognitionActivity recognition aims to recognize the actions and goals of one or more agents from a series of observations on the agents' actions and the environmental conditions. Since the 1980s, this research field has captured the attention of several computer science communities due to its strength in providing personalized support for many different applications and its connection to many different fields of study such as medicine, human-computer interaction, or sociology.
Radar de régulation de distanceUn radar de régulation de distance (en anglais, adaptive cruise control, ou ACC) est un ajout au système de régulateur automatique de vitesse que l'on retrouve sur certaines automobiles modernes. L'appareil utilise un radar ou un laser pour mesurer la distance et la vitesse d'approche d'un véhicule précédant l'utilisateur ce qui permet d'ajuster la vitesse automatiquement afin de maintenir une distance de sécurité pour éviter la collision, puis de reprendre la vitesse de consigne en mémoire lorsqu'il n'y a plus d'obstacle ou de véhicule dans la distance programmée.
EXPEEDThe Nikon Expeed /video processors (often styled EXPEED) are media processors for Nikon's digital cameras. They perform a large number of tasks: Bayer filtering, demosaicing, corrections/dark-frame subtraction, reduction, image sharpening, , gamma correction, image enhancement/Active D-Lighting, colorspace conversion, chroma subsampling, framerate conversion, /chromatic aberration correction, /JPEG encoding, video compression, display/video interface driving, , face detection, audio processing/compression/encoding and computer data storage/data transmission.
Masque flouLa photographie numérique a popularisé l'utilisation du masque flou pour accentuer les images, c'est-à-dire précisément pour améliorer leur piqué. Le principe de cette méthode avait néanmoins été imaginé dans le cadre de la photographie argentique. À la différence de la méthode de déconvolution qui implique des connaissances précises de la chaîne d'acquisition de l'image, cette méthode ne peut prétendre restituer, même partiellement, une information définitivement perdue.
ActelActel Corporation (formerly NASDAQ:ACTL) was an American manufacturer of nonvolatile, low-power field-programmable gate arrays (FPGAs), mixed-signal FPGAs, and programmable logic solutions. It was headquartered in Mountain View, California, with offices worldwide. In November 2010, Actel was acquired by Microsemi for $430 million. Actel was founded in 1985 and became known for its high-reliability and antifuse-based FPGAs, used in the military and aerospace markets.
Bus errorIn computing, a bus error is a fault raised by hardware, notifying an operating system (OS) that a process is trying to access memory that the CPU cannot physically address: an invalid address for the address bus, hence the name. In modern use on most architectures these are much rarer than segmentation faults, which occur primarily due to memory access violations: problems in the logical address or permissions. On POSIX-compliant platforms, bus errors usually result in the SIGBUS signal being sent to the process that caused the error.
Biological oceanographyBiological oceanography is the study of how organisms affect and are affected by the physics, chemistry, and geology of the oceanographic system. Biological oceanography may also be referred to as ocean ecology, in which the root word of ecology is Oikos (oικoσ), meaning ‘house’ or ‘habitat’ in Greek. With that in mind, it is of no surprise then that the main focus of biological oceanography is on the microorganisms within the ocean; looking at how they are affected by their environment and how that affects larger marine creatures and their ecosystem.
Primary and secondary antibodiesPrimary and secondary antibodies are two groups of antibodies that are classified based on whether they bind to antigens or proteins directly or target another (primary) antibody that, in turn, is bound to an antigen or protein. A primary antibody can be very useful for the detection of biomarkers for diseases such as cancer, diabetes, Parkinson’s and Alzheimer’s disease and they are used for the study of absorption, distribution, metabolism, and excretion (ADME) and multi-drug resistance (MDR) of therapeutic agents.
Lime (outil)Une lime est un outil servant à usiner la matière. Une lime travaille par arrachement de petits morceaux du matériau, le travail s'effectue généralement en de multiples passages de la lime sur la pièce à usiner. Il en existe de multiples formes (plate, ronde, carrée, en feuille de sauge, en pilier) permettant de s'adapter à la forme à obtenir, avec des dessins de la râpe, plus ou moins grossier et, de formes différentes en fonction du matériau à travailler. Les limes sont couramment fabriquées en acier, les rainures sont martelées ou embouties.
