Object tags

There are two fundamental differences between the conventional barcodes and the contemporary RFIDs. First, RFIDs do not require line of sight— that is, objects tagged with RFID can be sensed in a wide area, and there is no need to individually scan all the objects in front of an optical scanner. Second, RFIDs offer item-level tagging— that is, each item within a product range can be uniquely identified (e.g., 109839 is a bottle oforangejuice manufactured by ABC Company ). However barcodes do not identify individual items they can only identify that this is abottle oforange juice manufactured by ABC Company. ... 

This policy is, in essence, similar to declaring a static array of objects tagged by in use flags, allocating and releasing slots in the array as objects are created and destroyed. 

A vector semispace is considered here as a vector space defined over the positive real numbers. In this way the additive group of the semispace is a semigroup, a group without reciprocal elements. DF sets like the quantum object tags already discussed in MQOS definition are subsets of some Hilbert semispace. 

More objective laboratory methods employ a mechanical device such as a Terg-O-Tometer (110). Food soils are appHed to microscope sHdes or glass tape rather than to actual plates. The soils are tagged with fluorescent materials or with dark pigment to faciUtate measurement of residual soil. Reflectance or transmittance may also be read directly (111). 

These bikes could be a wonderful transportation option, combining the efficiency, quiet and nonpollution of a bicycle with the ease of riding a small motorcycle. For these reasons, electric-assist bikes sell at the rate of over 200,000 per year in Japan. But in the United States, these bikes run up against a cultural barrier. Bicycle enthusiasts, who are less likely to object to their four-figure price tags, do not want a motor and do not want a bike that weighs 60 pounds. Others do not want to be seen riding to work. So U.S. sales have been poor. 

Object attributes are represented by columns in the table. Each session, instmctor, and client is assigned a unique identification tag, ID, which is used to implement links between the objects. Links between objects are represented by columns that contain the ID of the corresponding linked object. 

For object identifiers, names, keys, tags, and similar attributes, use associations. 

We have developed an in vitro digestion procedure, not as a substitute for in vivo studies, but as a useful adjunct. Our initial objective was to develop an in vitro procedure for measuring exchangeability, the fraction of the food mineral which exchanges with an extrinsic isotope tracer added to the food. This was expected to facilitate the measurement of food mineral absorption in humans by the extrinsic tag method. Secondary objectives were to determine if in vitro mineral solubility could be used to estimate potential... 

Tracking surveillance technology is varied in design and form. It ranges from simple beepers to sophisticated intelligent transportation systems. For example, there is radar to monitor over the horizon bi-static sensors for passive retrieval of emissions (cellular phones) or active sonar-hke capacity tagging systems that use projectiles to attach transmitters to moving objects illumination telescopic and detection systems. 

The essential commonness of the objects selected [by Duchamp] as readymades was [a trait] also related to the everyday esthetics of the Ash Can School of painting in New York. These painters of the grubby actuality of city life acquired their collective tag in the very month in which Duchamp unveiled his ready-made art in New York, in April 1916. In the same year,... 

Hence, the object om or nm that satisfies the ML principle (17) must also obey the M constraint equations (18). In addition, there is the normalization constraint (3). These may be tagged onto Eq. (17) by the conventional use of... 

Mechanistic features of SNAr displacement reactions involving amino nucleophiles have been the object of many investigations, a major point of interest being the occurrence of base-catalyzed paths. Strongly activated aryl halides react readily with ammonia and with primary and secondary amines to give the corresponding arylamines. Thus, for example, 2,4-dinitrofluorobenzene is used to tag the amino end of a peptide or protein chain. 

The ability to detect tagged expl products in a controlled-access scenario is the final objective of the vapor taggant development effort. To accomplish this, there are three steps (1) placement of the taggant in an expl product (2) extraction of the vapor taggant from the test object and (3) use of a detector of sufficient... 

A system based on grafted polymer synthetic objects (lanterns) is available from Mimotopes Pyt. Ltd.12 The system is composed of the synthetic objects (lanterns), RF-Tags (Transtems), software to track the synthesis (TranSort), and a cleavage system. Additional systems that are not commercially available have been reported. Workers at Aventis have developed a highly automated system based on the Mimotope lanterns.13 Recently workers at Millenium Pharmaceuticals reported the St AC system (Stratified Adressable System), a three-dimensional spatial array that allows discrete compounds to be synthesized using the same efficiency as the directed sorting approach.14... 

Motion analysis and particle tracking methods enable users to follow the movement over time of tagged particles, such as fluorescently labeled cell surface molecules, microtubules, nucleic acids, lipids, and other objects with subpixel resolution.287 These methods allow scientists to measure jc and y coordinates, velocity, mean displacement, mean vector length, and more.
