Image Tracing
In computer graphics, image tracing, raster-to-vector conversion or raster vectorization is the conversion of raster graphics into vector graphics. Background An image does not have any structure: it is just a collection of marks on paper, grains in film, or pixels in a bitmap. While such an image is useful, it has some limits. If the image is magnified enough, its artifacts appear. The halftone dots, film grains, and pixels become apparent. Images of sharp edges become fuzzy or jagged. See, for example, pixelation. Ideally, a vector image does not have the same problem. Edges and filled areas are represented as mathematical curves or gradients, and they can be magnified arbitrarily (though of course the final image must also be rasterized in to be rendered, and its quality depends on the quality of the rasterization algorithm for the given inputs). The task in vectorization is to convert a two-dimensional image into a two-dimensional vector representation of the image. It is not ...

Tracing (law)
Tracing is a legal process, not a remedy, by which a claimant demonstrates what has happened to his/her property, identifies its proceeds and those persons who have handled or received them, and asks the court to award a proprietary remedy in respect of the property, or an asset substituted for the original property or its proceeds. Tracing allows transmission of legal claims from the original assets to either the proceeds of sale of the assets or new substituted assets. Tracing ordinarily facilitates an equitable remedy, and is subject to the usual limitations and bars on equitable remedies in common law countries. In many common law countries, there are two concurrent processes, tracing at common law and tracing in equity. However, because the right to trace at common law is so circumscribed, the equitable process is almost universally relied upon, as equitable tracing can be performed into a mixed fund. Illustrations "Tracing is thus neither a claim nor a remedy. It is merel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Contact Tracing
In public health, contact tracing is the process of identifying persons who may have been exposed to an infected person ("contacts") and subsequent collection of further data to assess transmission. By tracing the contacts of infected individuals, testing them for infection, and isolating or treating the infected, this public health tool aims to reduce infections in the population. In addition to infection control, contact tracing serves as a means to identify high-risk and medically vulnerable populations who might be exposed to infection and facilitate appropriate medical care. In doing so, public health officials utilize contact tracing to conduct disease surveillance and prevent outbreaks. In cases of diseases of uncertain infectious potential, contact tracing is also sometimes performed to learn about disease characteristics, including infectiousness. Contact tracing is not always the most efficient method of addressing infectious disease. In areas of high disease prevalenc ...

Tracer Ammunition
Tracer ammunition (AMO) (Tracers) are bullets or cannon-caliber projectiles that are built with a small pyrotechnic charge in their base. When fired, the pyrotechnic composition is ignited by the burning powder and burns very brightly, making the projectile trajectory visible to the naked eye during daylight, and very bright during nighttime firing. This allows the shooter to visually trace the flight path of the projectile and thus make necessary ballistic corrections, without having to confirm projectile impacts and without even using the sights of the weapon. Tracer fire can also be used as a marking tool to signal other shooters to concentrate their fire on a particular target during battle. When used, tracers are usually loaded as every fifth round in machine gun belts, referred to as four-to-one tracer. Platoon and squad leaders will load some tracer rounds in their magazine or even use solely tracers to mark targets for their soldiers to fire on. Tracers are also som ...

Semiconductor Curve Tracer
A semiconductor curve tracer (also known as a semiconductor parameter analyzer) is a specialised piece of electronic test equipment used to analyze the characteristics of discrete semiconductor devices such as diodes, transistors, and thyristors. Based on an oscilloscope, the device also contains voltage and current sources that can be used to stimulate the device under test (DUT). Operation The function is to apply a swept (automatically continuously varying with time) voltage to two terminals of the device under test, and measuring the amount of current that the device permits to flow at each voltage. This so-called V-I (voltage versus current) graph is displayed on an oscilloscope screen. Configuration includes the maximum voltage applied, the polarity of the voltage applied (including the automatic application of both positive and negative polarities), and the resistance inserted in series with the device. The main terminal voltage can often be swept up to several thousand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tracking And Tracing
In the distribution and logistics of many types of products, track and trace or tracking and tracing concerns a process of determining the current and past locations (and other information) of a unique item or property. This concept can be supported by means of reckoning and reporting of the position of vehicles and containers with the property of concern, stored, for example, in a real-time database. This approach leaves the task to compose a coherent depiction of the subsequent status reports. Another approach is to report the arrival or departure of the object and recording the identification of the object, the location where observed, the time, and the status. This approach leaves the task to verify the reports regarding consistency and completeness. An example of this method might be the package tracking provided by shippers, such as the United States Postal Service, Deutsche Post, Royal Mail, United Parcel Service, AirRoad, or FedEx.

Family Tracing And Reunification
Family Tracing and Reunification (known as FTR) is a process whereby disaster response teams locate separated family members and reunite them following natural and human catastrophes. During major crises, children can become separated from their families for a wide range of reasons, and government disaster relief agencies as well as NGOs have developed inter-agency procedures to return children, and other vulnerable people, to their families. Mobile technology UNICEF has developed a tool called RapidFTR that uses smartphones to register and monitor children who have become separated during a natural disaster or conflict, with a view to reunifying children with their parents. While the tool has been assessed as having some benefits, it has reportedly encountered significant challenges relating to relevance of the design and heavy dependence on internet in contexts with limited access. The RapidFTR platform showed some promise and was used to track displaced children after Typhoon Ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curve Sketching
In geometry, curve sketching (or curve tracing) are techniques for producing a rough idea of overall shape of a plane curve given its equation, without computing the large numbers of points required for a detailed plot. It is an application of the theory of curves to find their main features. Basic techniques The following are usually easy to carry out and give important clues as to the shape of a curve: *Determine the ''x'' and ''y'' intercepts of the curve. The ''x'' intercepts are found by setting ''y'' equal to 0 in the equation of the curve and solving for ''x''. Similarly, the ''y'' intercepts are found by setting ''x'' equal to 0 in the equation of the curve and solving for ''y''. *Determine the symmetry of the curve. If the exponent of ''x'' is always even in the equation of the curve then the ''y''-axis is an axis of symmetry for the curve. Similarly, if the exponent of ''y'' is always even in the equation of the curve then the ''x''-axis is an axis of symmetry for the c ...

Call Tracing
In telecommunication, call tracing is a procedure that permits an entitled user to be informed about the routing of data for an established connection, identifying the entire route from the origin to the destination. There are two types of call Call or Calls may refer to: Arts, entertainment, and media Games * Call, a type of betting in poker * Call, in the game of contract bridge, a bid, pass, double, or redouble in the bidding stage Music and dance * Call (band), from Lahore, Paki ... tracing. Permanent call tracing permits tracing of all calls. On-demand call tracing permits tracing, upon request, of a specific call, provided that the called party dials a designated code immediately after the call to be traced is disconnected.

Retrograde Tracing
Retrograde tracing is a research method used in neuroscience to trace neural connections from their point of termination (the synapse) to their source (the cell body). Retrograde tracing techniques allow for detailed assessment of neuronal connections between a target population of neurons and their inputs throughout the nervous system. These techniques allow the "mapping" of connections between neurons in a particular structure (e.g. the eye) and the target neurons in the brain. The opposite technique is anterograde tracing, which is used to trace neural connections from their source to their point of termination (i.e. from cell body to synapse). Both the anterograde and retrograde tracing techniques are based on the visualization of axonal transport. Techniques Retrograde tracing can be achieved through various means, including the use of viral strains as markers of a cell’s connectivity to the injection site. The pseudorabies virus (PRV; Bartha strain), for example, may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anterograde Tracing
In neuroscience, anterograde tracing is a research method which is used to trace axonal projections from their source (the cell body or soma) to their point of termination (the synapse). A hallmark of anterograde tracing is the labeling of the presynaptic and the postsynaptic neuron(s). The crossing of the synaptic cleft is a vital difference between the anterograde tracers and the dye fillers used for morphological reconstruction. The complementary technique is ''retrograde tracing'', which is used to trace neural connections from their termination to their source (i.e. synapse to cell body). Both the anterograde and retrograde tracing techniques are based on the visualization of the biological process of axonal transport. The anterograde and retrograde tracing techniques allow the detailed descriptions of neuronal projections from a single neuron or a defined population of neurons to their various targets throughout the nervous system. These techniques allow the "mapping" of conne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
