X-ray crystallography for the study of nickel and iron salicylaldimines
… for the series. The trinuclear compounds form an isosceles triangle of metal atoms with the isopropyl analog showing an overall antiferromagnetic interaction with J=+11.386 and J23=-13.891. Lastly, xanthene spirolactam derivatives were structurally analyzed to determine binding modes for their …

SYNTHESIS OF POLYMER STRUCTURES FOR INCREASING ENERGY CONVERSION IN SOLAR CELLS
… wasted. I have simulated the performance of isosceles triangles (IT), right triangles (RT), and metal-coated isosceles triangles (MC). Three figures of merit are introduced to determine the optimized design for the seasonal and daily trajectory of sun scenarios. The optimized apex angle is 54 …

Facilitando o ensino de geometria com o uso do software livre Wingeom em uma turma do 8° ano.
… triangles on the sides and angles (equilateral, isosceles, scalene). Thus, the research developed through access to computers located in the school, using the software Wingeom and lectures over a period of about a month. At the end of this period, we applied a survey from which we extract a …

Strain transducers for active control
… is composed of a piezoceramic actuator shaped as isosceles triangle with a velocity sensor at its tip. A fully coupled mobility model has been developed, which predicts the response of the sensor-actuator pair more accurately than the conventional modeling method. The implementation of a 16 …

Design of Surface Texture for the Enhancement of Tribological Performance
… shapes: rectangle, oblique triangle and isosceles triangle. The numerical model uses Jakobsson-Floberg-Olsson (JFO) cavitation theory to predict the load-carrying capacity of textures. It is found that the value of cavitation pressure plays an important role in the implementation of the …

Rovibrational Dynamics of Nuclei and Molecules
… nucleus based on point ↵-particles restricted to isosceles triangular configurations, inspired by linear chain and equilateral triangular Skyrmions. The configuration space is not a manifold but has a graph-like structure, and we make use of Quantum Graph Theory to study the quantized dynamics. …

Spectral problems on triangles and disks: Extremizers and ground states
… is known to be minimal for the degenerate acute isosceles triangle (rather than for the equilateral), while the first eigenvalue (n=1) is 0 for every triangle. We show the third eigenvalue is minimal for the equilateral triangle. The second part of the thesis is concerned with the properties of …

[mu]SR measurement of the magnetic penetration depth and coherence length in the high-T superconductor YBa₂Cu₃O₆ 95
… the vortices in place, the aspect ratio of the isosceles triangle defining the vortex lattice will change. Unfortunately, the degree of disorder, where disorder is defined as the mean deviation of the vortices from their ideal positions in the lattice relative to the distance between vortices, …

Methodological Developments for an Improved Evaluation of Climate Change Impact on Flow Hydrodynamics in Estuaries
… characteristic of the triangular grids, various isosceles triangles with different vertex angles are considered. Moreover, diverse well-known second-order time stepping techniques such as Leap-Frog, Adams-Bashforth and improved Euler are studied in combination with the C-grid semi discrete …

Human Visual Navigation: Effects of Visual Context, Navigation Mode, and Gender
… angle, on route layouts based on equilateral or isosceles triangles. A compressed range of responses was found. Higher overall accuracy was observed when a display with smaller desktop computer monitors was used; especially when simulated self-motion was actively controlled with a steering wheel …

Buckling response of symmetrically laminated composite plates having a trapezoidal planform area
… plates having a planform area in the shape of an isosceles trapezoid. The loading is assumed to be inplane and applied perpendicular to the parallel ends of the plate. The tapered edges of the plate are assumed to have simply supported boundary conditions, while the parallel ends are assumed to …

Reliability Analysis of the HEC-18 Scour Equation and AASHTO Deep Foundation Design Codes
… index. It was found that for a channel with isosceles trapezoidal cross section, the channel side slope has negligible influence on the reliability index, while for a channel built by trapezoidal main channel with over banks, the reliability index can change when the channel slopes change. …

Exotic phenomena in rare-earth based geometrically frustrated magnets
… two RE pyrochlore oxides (RE2TM2O7) and a 2D isosceles triangular lattice material K3Er(VO4)2. Spin-1/2 antiferromagnetic (AFM) 2D triangular lattice magnets are an archetype of geometric frustration. While these materials are theorized to host a variety of different ground states and exotic …

A Variety of Proofs of the Steiner-Lehmus Theorem
<p>The Steiner-Lehmus Theorem has garnered much attention since its conception in the 1840s. A variety of proofs resulting from the posing of the theorem are still appearing today, well over 100 years later. There are some amazing similarities among these proofs, as different as they seem to be. …
