In this paper we examine two methods for using relative contact size as an interaction technique for 3D environments on multi-touch capacitive touch screens. We refer to interpreting relative contact size changes as “pressure” simulation. We conducted a 2 x 2 withinsubjects experimental design using two methods for pressure estimation (calibrated and comparative) and two different 3D tasks (bid...

Soil wettability is especially important for rainfed agriculture in climates with a dry period during the growing season. The effect of aggregate structure and soil organic C content on wettability of soil aggregates was determined for grassland (grass) and tilled fields (tillage). Soil organic C, plastic limit, aggregate total porosity, and wettability at 100 mm (rapid wetting) and 300 mm (slo...

Bellows are special structures that require high strength as well as good flexibility. The design, manufacture, and analysis of bellow tubes thus are more complicated. Test of bellows to understand their mechanical behavior, and to verify a design purpose finite element program is needed for practical use. In this paper, digital-image-correlation method is applied to measure the stiffness of si...

This paper presents results of testing twelve hollow square reinforced concrete specimens wrapped with Carbon fibre reinforced polymer CFRP. The effect of ply configuration on the behaviour of the specimens is investigated. All specimens were 800mm high and had the dimensions of 200mm× 200mm in cross-section and a hollow core of 80mm× 80mm. The specimens were divided into four groups with three...

Lexical information can bias categorization of an ambiguous phoneme and subsequently evoke a shift in the phonetic boundary. Here, we explored the extent to which this phenomenon is perceptual in nature. Listeners were asked to ignore auditory stimuli presented in a typical oddball sequence in which the standard was an ambiguous sound halfway between /t/ and /p/ embedded in a Dutch word normall...

In this study, the longitudinal and hoop tensile strengths of an industrial ±55° Glass Reinforced Epoxy (GRE) pipe with eighteen layers as well as the associated failure mechanisms are determined. To obtain the longitudinal and hoop tensile strengths values, three specimens are cut from the studied GRE pipe in each direction. A comparison is done between both the strength values, and the fractu...

The complications of impaction bone grafting in revision hip replacement includes fracture of the femur and subsidence of the prosthesis. In this in vitro study we aimed to investigate whether the use of vibration, combined with a perforated tamp during the compaction of morsellised allograft would reduce peak loads and hoop strains in the femur as a surrogate marker of the risk of fracture and...

In this paper, our aim was making a metric space on hoop algebras, because of that, we introduced the notion valuation maps from F-quasi-valuation map based hoops and related properties them are investigated. By using these notions, quasi-metric space. The continuity operations is studied with topology induced by quasi-valuation. Also, homomorphism investigated that under which condition an map...

Introduction: Tension and chaos are considered as a socioeconomic phenomenon that can have adverse effects on individuals, organizations, and the community if not properly managed. Therefore, this study was aimed to investigate the factors affecting the formation of tension and chaos among nurses of Yazd Province, Iran. Methods: This exploratory mixed methods research was conducted on nurses s...

BACKGROUND AND PURPOSE We observed that the second application of cerebrospinal fluid (CSF) from subarachnoid hemorrhage (SAH) patients onto cerebral arterial segments in vitro produces a greater contraction than does the initial application. It was hypothesized that the difference between the first and second applications of SAH CSF was due to the activity of thrombin. METHODS Canine vertebr...
