Natural User Interface Design for Digital Painting Based on User Behavior Patterns

To deal with these existing problem, we have some design principles here: Define nature painting behavior from basic holding pen posture, reducing redundant action. Redesign those interactions in state of dynamic behavior patterns, to reduce the negative impact of cognitive migration. Rational use of cognitive migration phenomenon. Those widely accepted shortcuts (such as Undo) ensure working efficiency, changing may increase unnecessary cognitive load.

Painting in the tropics

Painting in the tropics

The lean of the palm tree introduced a note of chaos; an uncomfortable space that is an unpleasant dream rather than a peaceful utopia. Painted in his Sydney studio, this idea of remote nature is the reappraisal of a threatened natural state of existence. It reflected the relationship between humans and nature. It depicted a fanciful history, set in the urban landscape as exoticism. Humboldt’s noble vegetation is recast as a wilted heap, suffocating in atmospheric gloom. Quilty’s landscape distilled an island of remoteness and echoes admonitions of global warming, as it transposes nineteenth- century utopian goals onto a reality of decrepitude. The paradise of tranquil utopia, however, was captured by Arthur Streeton in Moonlight, Magnetic Island (1924). Lit only by moonlight, the remote northern tropics were depicted in his Heidelberg style to capture a vision of an untainted and pristine world, whereas Quilty’s painting incorporates the effects of contemporary pollution and environmental threat.

Observations of artificial and natural optical emissions at the HAARP facility

camera, the curved and tilted virtual image behind the mirror requires a large depth of field, which depends on the absolute focal length of the lens and the F-number of the lens used. To operate at the lowest possible F-numbers, and therefore the highest sensitivity, depth of field considerations require the system to employ relatively large mirrors far from the camera in order to achieve acceptable focus. For our sys- tem, the focal length l=50 mm, the F-number f =1.2, and choosing 2 pixels as an acceptable circle of confusion c on a 13 mm × 13 mm CCD chip binned down to 256 × 256 pix- els ( ∼ 0.1 mm/pixel), we get a hyperfocal distance h ≈ l 2 /fc of approximately 20.8 m. The approximate depth of field d can be computed from the hyperfocal distance h of the lens/detector combination and the distance x to the image as d ≈ 2hx 2 /(h 2 − x 2 ). For x=2 m, d is approximately 25 cm, just barely adequate to accommodate the tilted virtual image behind the 50 cm primary mirror selected for the system. As the mirror is moved toward the camera, the depth of field falls off more rapidly than the image shrinks in size and depth (as- suming smaller mirrors are used to fill the 15 ◦ field of view), so the ∼ 2 m mirror distance is a practical minimum for this lens/detector combination, confirmed by experiments with mirrors of various sizes. In practice, spherical aberration and defects in the low-cost mirrors are also non-negligible, so depth of field is not the only limitation.

Temporal dynamics of fish assemblages of natural and artificial tropical estuaries

mesh) because this gear type could be used across the greatest range of habitats in the sampling area (John- ston & Sheaves 2008) while producing the widest taxo- nomic and size representation possible (Sheaves et al. 2007). Although the present study probably provided good representation of the small and juvenile compo- nents that make up the bulk of fish in tropical estuarine assemblages (Blaber 1980, Robertson & Duke 1990b), larger mobile species were likely to be underrepre- sented (Sheaves & Johnston 2009); consequently, this study focuses on the small and juvenile component of the fauna. Cast nets operated by the same individual were used for all nekton collection. Samples were col- lected from a 4.3 m dinghy, fitted with an electric motor to reduce potential for disturbance, and followed the protocols set out by Sheaves et al. (2007). Samples were collected over the lower half of the tide, when small fish are forced out of the mangroves into the main channel of the estuary. Sampling was concen- trated along the banks of the estuaries because these areas contain the bulk of small fish throughout most of the lower part of the tidal cycle (Johnston & Sheaves 2008). Fish less than 5 mm body depth were excluded from analyses because these were below mesh selec- tion size and so unlikely to be well represented in sam- ples.

The neural basis of perceived intensity in natural and artificial touch

The neural basis of perceived intensity in natural and artificial touch

Having established that varying pulse train parameters can elicit a large number of discriminable intensity percepts, and that these percepts span a wide range of intensities, we sought to directly compare the magnitude of electrically evoked sensations to that of mechanically evoked ones. To this end, subjects were instructed to match mechanical skin indentations on their intact hand to electrical stimulation such that the sensory magnitude of the former matched that of the latter. This process was repeated for electrical stimuli that spanned the range of perceptible and comfortable PWs and PFs. We found that PW and PF were approximately linear functions of indentation depth matched for perceived magnitude (Fig. 4A-D). The slope of the functions obtained by varying PF and PW were consistent for each electrode contact but varied across contacts. Electrode contacts that yielded a high slope for indentation depth vs. PF also yielded a high slope for indentation depth vs. PW (Fig. 4E, r=0.96). The slopes of the functions were likely affected by several factors including the mechanical sensitivity at the location of the indentation, which probably varied across skin locations, and the electrical sensitivity of the stimulated fascicle, which varied according to its geometry and distance from the stimulating electrode (see ÒBiophysical model of afferent recruitmentÓ in supplementary materials). As was the case with the magnitude estimates, PW and PF had different effects on matched depths when stimulation was expressed in terms of the average stimulation current ( ! !∀# ) (t-test comparing

Natural and artificial routes to pluripotency

Natural and artificial routes to pluripotency

Consistent with the low frequency for bona fide iPS cells is the scarcity with which viable transgenic adult mice can be generated through either chimera formation or tetraploid comple- mentation (Boland et al., 2009; Zhao et al., 2009). Furthermore, recent reports employing in depth molecular analyses suggest that the successful generation of iPS cells as measured by morphological criteria, molecular marker expression (Tra1-60/ 1-81, SSEA1/mouse, SSEA3/human, Nanog and Oct4 (Brambrink et al., 2008)), promoter methylation status and the ability to give rise to numerous types of differentiated progeny during teratoma formation, may overestimate the number of bona fide iPS cells generated. For instance, the typically per- formed analysis of DNA methylation patterns for the Oct4 and Nanog promoters reveals small but detectable differences between ES cells and iPS cells (Maherali et al., 2007; Okita et al., 2007; Smith et al., 2009; Takahashi and Yamanaka, 2006; Wernig et al., 2007), indicating a sometimes minute change in the overall density of methylation marks (Boyes and Bird, 1992; Hanna et al., 2008; Smith et al., 2009). This might affect endogenously produced Oct4 levels and the extent of down- stream reprogramming since Oct4 levels are greatly tuned for maintenance of pluripotency (Niwa et al., 2000). Examples illustrating the effect of near-miss of complete reprogramming include similarity but not identity in ESCs and iPS cells of 3’UTR length (Ji and Tian, 2009), heightened promoter occupancy in target genes for Oct4, Sox2 and Nanog (Huang et al., 2009) and differences in the DNA methylomes (Doi et al., 2009; Pick et al., 2009). Differences in 3’UTR length through the use of alterna- tive polyadenylation sites may affect the presence of cis- regulatory elements for mRNA stability and/or translatability (Ji and Tian, 2009) and lead to post-transcriptional changes in the proteome of iPSC compared to ESCs. A more than 10-fold increased promoter occupancy observed

TSUNAMI PROTECTION BY NATURAL AND ARTIFICIAL BARRIERS

TSUNAMI PROTECTION BY NATURAL AND ARTIFICIAL BARRIERS

A fresh analysis of the field survey results of 2004 Indian Ocean tsunami was presented by Patnaik et al. (2012) with focus on the tsunami run-up heights and inundation. It was observed that the Andhra coast was largely affected by the tsunami and in general the intensity of the tsunami decreased with run-up heights of 4.5m in the south to around 2m in the north with the distance of inundation varying from 60m to 900m. The authors identified the interdependency between the tsunami run-up height and inundation with the physical setup of the shoreline and the width of continental shelf. The vital role of local features such as dunes, vegetation and steepness of beaches in reducing the impact of tsunami was also mentioned. It was noted that the orientation of offshore depth contours had a significant influence in tsunami propagation and inundation. Beach slope was identified as another crucial parameter influencing the tsunami run- up and inundation. Coastal Characteristic Index (CCI) was proposed to represent the dependency of run-up heights and inundation on the independent tsunami parameters like shape factor and slope of the coast, length and width of mangrove/vegetation cover, coastal construction, and good correlation could be obtained between CCI and run-up as well as inundation. The average CCI was found to be inversely related to inundation, implying that coasts with lower value of CCI would be more vulnerable to tsunami inundation and thus, CCI was could be an effective parameter for assessing the tsunami hazard of any coast.

Investigation on artificial blood or substitute blood replace the natural blood

Investigation on artificial blood or substitute blood replace the natural blood

With the advance in bio-technology, there will be more blood substitutes available, which could permanently replace the natural blood. The substitute holds this kind ofpromise is artificial blood powder. The ultimate goal of the transmission is the transmission system without any side effects and effective for the treatment. Although the current system of homologous blood has lack of issues, but it is much less expensive with fewer side effects, and is more acceptable. However, new technologies need to produce increasingly effective alternative for blood transfusion medicine. At present, the use of artificial blood due to short half-life and potential toxicity and costs, access to raw materials and the FDA is difficult. This caused temporary change to replace the red blood cells and the use of homologous blood transaction. Although the use of blood substitutes has higher safety incidence of viral infections like HIV, certainly in the near future, blood substitutes such as oxygen carrying will bring a new dimension in transfusion medicine.

Natural and artificial orbits around the Martian moon Phobos

Natural and artificial orbits around the Martian moon Phobos

The derivation of the lighting condition is a purely geometrical analysis. Since the interest is for the positions in Phobos’ neighborhood, the analysis is conducted in the Hill’s frame of its orbit around Mars. The kinematics must now consider also the motion of the Sun in this frame, using a restricted four-body model to evaluate the FOV of the Sun over time for points around Phobos. Usually two simplified models are used for the R4BP analysis, assuming that all the three massive bodies rotate in couples of circular and co-planar orbits. It should be remarked that this approxima- tion is not coherent, since the resulting 3B motion is not a solution of the Newton’s equations of motion [91]. The simplified circular-co-planar models are the Concentric Circular Model (CCM), where two smaller bodies revolve around the massive one (like the situation of two planets in the Solar System, or two natural satellites around their central planet), and the Bicircular Model (BCM), where one body revolves around an- other in cascade (like the chain Sun-planet-moon). The BCM is obviously the case of the Sun-Mars-Phobos R4BP, but here two problems arise: first, the Mars’ heliocentric orbit is the second most elliptic among the Solar System’s planets; second, Phobos’ orbit is equatorial, which is the resulting orbital plane is inclined with respect to its ecliptic plane by Mars’ axial tilt θ M = 25.19 ◦ . These situations are not critical because

Is artificial data useful for biomedical Natural Language Processing algorithms?

Is artificial data useful for biomedical Natural Language Processing algorithms?

In the NLP community, this low-resource prob- lem is typically addressed by generating comple- mentary data artificially (Poncelas et al., 2018; Edunov et al., 2018). This approach is also gaining attention in biomedical NLP. Most of these stud- ies present work on the generation of short text (typically under 20 tokens), given structural infor- mation to guide this generation (e.g., chief com- plaints using basic patient and diagnosis informa- tion (Lee, 2018)). Evaluation scenarios for the utility of the artificial text usually involve a sin- gle downstream NLP task (typically, text classifi- cation).

Artificial reproduction of neotropical fish: Extrusion or natural spawning?

Artificial reproduction of neotropical fish: Extrusion or natural spawning?

Currently, the formation of wild fish broodstocks that have adequate genetic variability is hampered due to a number of factors, such as pollution, deforestation and dam construction, which are promoting the reduction of natural stocks and, in some situations, the extinction of neotropical fishes’ large-sized stocks. Accordingly, the maintenance and survival of broodstocks in hatchery stations, government research agencies and private re- search are considered of great importance [1]. However, several causes of broodstock mortality have not yet been overcome in the traditional management protocols to produce fingerlings of neotropical species; one of these is the absence of induction techniques for reproduction, which allows a high production of offspring without the high risk broodstock sacrifice.

Safety of artificial turf and natural grass sports surfaces

Safety of artificial turf and natural grass sports surfaces

When submitted to a severe impact a natural surface has the ability to permanently deform, crush and collapse. This behavior is a very effective means of dissipating the energy of a severe blow and is similar to the way that a crash helmet is designed to absorb significant impacts. Unlike a crash helmet that is only designed for one severe blow, a natural grass surface can be repaired, maintained and made ready for another future impact. The ability of a natural grass surface to effectively absorb the energy of a severe blow is of significant benefit in preventing severe injury, most importantly head injuries.

Painting with Overglazes

Painting with Overglazes

You have a wide range of oil mediums from which to choose (see chapter 4), but most china painters now use some combination of balsam of copaiba and the oils of lavender, clove and anise. The decision is based mostly on how quickly they like their paint to dry and how thickly they like to apply it. Turpentine and fat oil are seldom used today except for techniques like traditional Dresden style painting. There are also water-solu- ble mediums. I almost always mix my colors with plain water, or one of the glycols. Regardless of the medium, you’ll soon develop a feel for how thick you like it to be and how fast you want it to dry.

Study of Material Properties and Integrity of Natural and Artificial Rubber Composites

Study of Material Properties and Integrity of Natural and Artificial Rubber Composites

With the variation in the percentage of ferrite loading and sulphur the modulus value is observed to be changing in some format for certain level and change in profile is obtained in the modulus value. The modulus value increases with increase in level of loading of cacium ferrite and sulphur to a level of 70% calcium ferrite and 4gm sulphur. With further increse in the percentage of calcium ferrite and sulphur the modulus value start decreasing. Upto a level of ferrite and sulphur loading the modulus value is directly proportional to the loading and later it is inversely proportional to further increase in the percentage of ferrite and sulphur loading with natural rubber and nitrile rubber. So based on the requirement of modulus value the loading of calcium ferrite and sulphur percentage with rubber can be decided.
