[No title] Artifacts, rocks, grasses, etc. were labeled and identified and drawn on grid paper. Artifact scatters and roasting features are experiencing the majority of damage from both surface erosion and gullying as well as from human visitors. Artifacts include lithic debris, groundstone, charcoal, burned bone and sherds, indicating a Pueblo II formative as well as protohistoric and 19th century Pai occupation. www.nps.gov /grca/archaeology/text/FY1994.txt   (21960 words)

GameDev.net -- Tile/Map-Based Game Techniques: Base Data Structures The stationary units, on the other hand, are the buildings or building segments that do not move. Once a stationary unit is placed on the map, it stays there until the player removes it or an enemy unit destroys it. Since there can only be one stationary unit per map cell, the map cell needs only to have a pointer to such a unit. www.gamedev.net /reference/programming/features/arttilebase/page3.asp   (804 words)

[No title] Artifact scatters and roasting features continue to experience the most damage from physical impacts such as surface erosion and visitor-related impacts like trailing. Artifacts are dominated by groundstone with lesser amounts of lithic debris and a few sherds (corrugated graywares and Cerbat Brownware). Some pedestalling of smaller artifacts due to locally heavy rain has occurred at Locus A. There are still palm-sized sherds and decorated wares on the surface indicating that visitation during the 20th century has been virtually nonexistent or that the artifacts were uncovered recently due to the lack of available sand in the system. www.nps.gov /grca/archaeology/text/FY1996.txt   (22293 words)

Technical considerations in Magnetic Resonance Angiography   (Site not responding. Last check: 2007-10-26) Flip angle and TR are chosen to obtain maximum contrast between fresh unsaturated in flowing blood and saturated stationary tissue. The maximum contrast between flowing blood and stationary tissue is obtained when the blood is exposed to only one RF pulse, with immediate read-out, after which the blood is replaced by fresh unsaturated blood. Stationary tissue at point A will have different phases of transverse magnetization compared to tissue B. Tissues in A and B precess with a higher frequency due to a positive lobe and with a lower frequency due to the negative lobe. mripractice.tripod.com /mrpractice/id24.html   (3475 words)

GameDev.net - Tile/Map-Based Game Techniques: Base Data Structures Artifact is currently in pre-release, with full release scheduled for Fall 1999. Such common elements include an indicator of the type of map cell (for instance, the terrain), the structure (or structure segment) built on the cell, and a pointer to the first mobile unit on the map. Fortunately, Artifact is a client-server game so the client software running on the player's PC generally doesn't have to deal with all of this information. www.gamedev.net /reference/articles/article837.asp   (2061 words)

Magnetic Resonance Technology IP - MRI Artifacts - Intro, Index A-I An image artifact is a structure not normally present but visible as a result of a limitation or malfunction in the hardware or software of the MRI device, or in other cases a consequence of environmental influences as heat or humidity or it can be caused by the human body (blood flow, implants etc.). Artifacts may be very noticeable or just a few pixels out of balance but can give confusing artifactual appearances with pathology that may be misdiagnosed. Changes in patient position, different pulse sequences, metallic artifacts, or other imaging variables can cause image distortions, which can be reduced by the operator; artifacts due to the MR system may require a service engineer. mr-tip.com /serv1.php?type=art&sub=Cerebro+...+Fluid+Pulsation+Artifact   (232 words)

Reduction of motion artifact in pulse oximetry by smoothed pseudo Wigner-Ville distribution | Journal of ... Therefore, the reduction of motion artifacts is of particular concern in the development of pulse oximeters to be applied in ambulatory, pediatric and trauma settings, as well as for implementing them into wearable devices for personal home healthcare [8]. By assuming that the artifact is a linear addition to the pulsatile photoplethysmographic (PPG) signal, the original signal can be reconstructed from the corrupted signal [9-11]. A recently proposed PPG artifact reduction methodology was based on the inversion of a nonlinear physical artifact model and could significantly reduce the effect of changes of probe coupling [8,12]. bmc.ub.uni-potsdam.de /1743-0003-2-3/text.htm   (4608 words)

Comments on 12849 | Ask MetaFilter Yup, they would feel gravity, since they're not freely falling any more (the floor of their magical stationary space station is keeping them from doing that.) "Weightlessness" is a consequence of being in free-fall — this was Einstein's big realization that led him to invent General Relativity. I don't want to confuse your niece, but by "stationary" we all assume you mean disregarding the fact that the earth is also rotating. She didn't articulate an understanding of the difference between scalar and vector values, for example, but she did seem to understand that there's a difference between having a speed and having a direction. ask.metafilter.com /mefi/12849   (1812 words)

Theoretical Comparison of Fourier and Wavelet Encoding in Magnetic Resonance Imaging   (Site not responding. Last check: 2007-10-26) Artifact is treated according to whether or not the source of the variation in the measured data is stationary. The basic difference between artifacts due time variations and those due to stationary effects is that, in the time-varying case, the eigenvalues of the point-spread operator are altered, which fundamentally changes the imaging process. Equation (31) is a statement in matrix representation of the result that the eigenvalues of the point-spread matrix are altered due to the time-dependent weighting of the measurements and is applicable in any case where there is some variable weighting of the transform domain data. splweb.bwh.harvard.edu /pages/papers/panych/ieeewav/ieeewav.html   (6735 words)

Methodology Applied To Bear Figurine Part 2 For the Topics In Material Culture course, the first term assignment requires the development of a personal artifact analysis methodology, which is to be applied to an object. This aspect of the artifact analysis only truly works when applied to numerous artifacts at once, to properly classify them in relation to each other. When music wound, bottom half stationary, upper torso moves in essentially in small circle, because of dress covers lower body, dress moves too, gives overall effect of walking in fact only upper shifting in circle, and lower stationary. individual.utoronto.ca /spike/Bear_Method2.htm   (373 words)

Re: SUO: RE: RE: RE: StationaryArtifact and Time -- defaults Matthew -- I agree that "stationary" is not a necessary property of many artifacts (especially structures) normally thought of as stationary. For the moment, Ian's "stationary" class can be used to hold objects which are stationary by default, and the class can be refined when the form for probabilistic assertions has been agreed on. There are, however, some artifacts that can probably be defined as "stationary" even now, such as buildings so large that they will surely never be moved, and stay in one place from the time they are built to the time the are destroyed. grouper.ieee.org /groups/suo/email/msg07227.html   (696 words)

SylverFyre's Unreal2 XMP Playguide A teams node can only register artifacts when it is online, this requires the team to have more than 800 units of energy available to it. When an artifact has been stolen its icon will flash and the announcer will inform you of this, an artifact which has been dropped stops flashing but the background remains dim until it is returned to the node or picked up again by another enemy. The Raptor makes a good artifact escape vehicle due to it's speed, but be aware that you're even more of a target and be ready to bail out before the thing explodes in a hail of heavy turret plasma bolts. www.eclipse.co.uk /sylverfyre/xmpguide.htm   (4648 words)

Research Abstract: 1996-10-00 Improved Methods for PAH Combustion Source Sampling To this end, a new Reduced Artifact Dilution Sampler (RADS) has been developed which consists of an isothermal/isokinetic stack probe, an automated dilution system and a reduced artifact sampling system for the collection of both vapor phase and particulate PAH. The RADS system is designed to collect PAH from the dilution system without significant artifact formation from acidic combustion gases or volatility loses from the particulate matter collected on the filter. Although the instrument is known to respond to the PAH aerosol concentration in some combustion sources, a performance evaluation was necessary for the mixture of emissions present in different stationary incinerator sources. www.arb.ca.gov /research/abstracts/a932-098.htm   (845 words)

Journal of NeuroEngineering and Rehabilitation | Full text | Reduction of motion artifact in pulse oximetry by smoothed ... In this paper, the smoothed pseudo Wigner-Ville distribution (SPWVD) is investigated as a novel motion artifacts resistant approach for estimating one of the most important vital signs – the blood oxygen saturation level (SpO2). Moreover, as the rate of change of SpO2 is relatively slow, SpO2 that changed by more than 2% per second was considered to be physiologically impossible, and was rejected from the calculation [22]. As compared to the performance of some of the commercial products evaluated in [24], which have SpO2 bias in the range of 0.4–12%, SpO2 precision in the range of 2–6%, and SpO2 PI in the range of 27–94%, the proposed SPWVD approach reports comparable performance. www.jneuroengrehab.com /content/2/1/3   (4740 words)
