Drones are becoming a novel means for delivery services. We present demonstration of drone services in skyway network that uses the service paradigm. A set experiments is conducted using Crazyflie drones to collect data on various positions drones, wind speed, direction, and battery consumption. run range flight patterns including linear, rectangular, triangular shapes.

In this study the dewetting process on micropillars of three different cross-sectional shapes, i.e. circular, square and triangular, was numerically investigated. The influence of the orientation of the triangular and square micropillars on the dewetting behavior was also studied. The numerical simulations showed that the cross-sectional shapes of the micropillars and their orientation play an ...

Geogrids are commonly used in transportation applications for stabilization and reinforcement due to their higher tensile strengths compared to geotextiles as well as the stiffness improvement they provide through arresting and interlocking granular particles in the geogrid apertures. Influenced by many factors, such as the aperture shape and size of geogrid, the degree of interlocking contribu...

background: molecular diversity of leishmania major and its morphological changes have become a controversial issue among researchers. some aspects of polymorphic shapes of amastigotes in clinical manifestations along with molecular variation were evaluated among suspected patients of some exceptional zoonotic cutaneous leishmaniasis locations in northern khuzestan, southwestern iran. methods: ...

in this paper, some elementary operations on triangular fuzzynumbers (tfns) are defined. we also define some operations on triangularfuzzy matrices (tfms) such as trace and triangular fuzzy determinant(tfd). using elementary operations, some important properties of tfms arepresented. the concept of adjoints on tfm is discussed and some of theirproperties are. some special types of tfms (e.g. pu...

The additive manufacturing (AM) technology possesses the potential to change the paradigm for manufacturing. To facilitate the successful uptake of AM technologies into a wider range of applications, AM needs metrological methods to measure, evaluate, validate techniques for both AM processes and AM parts. Two strategies are proposed for the optimisation of AM processes and the evaluation of th...

Most 3D shape analysis methods use triangular meshes to discretize both the shape and functions on it as piecewise linear functions. With this representation, shape analysis requires fine meshes to represent smooth shapes and geometric operators like normals, curvatures, or LaplaceBeltrami eigenfunctions at large computational and memory costs. We avoid this bottleneck with a compression techni...

The purpose of this study was to evaluate the effects of screwdriver handle shape, surface material and workpiece orientation on torque performance, finger force distribution and muscle activity in a maximum screwdriving torque task. Twelve male subjects performed maximum screw-tightening exertions using screwdriver handles with three longitudinal shapes (circular, hexagonal and triangular), fo...

Anisotropic flow is accredited to have effects from the initial state geometry and fluctuations in nuclear overlap region. The elliptic (${v}_{2}$) triangular (${v}_{3}$) coefficients of final particles are expected influenced by eccentricity (${ϵ}_{2}$) triangularity (${ϵ}_{3}$) participants, respectively. In this work, we study ${v}_{2}$, ${v}_{3}$, ${ϵ}_{2}$, ${ϵ}_{3}$, correlations among th...
