Optimum Choice of the Front Suspension of an Automobile

open access: yesЖурнал інженерних наук, 2019
The paper details the optimum choice of the front suspension of an automobile. The influence of suspension on the steering geometry is studied by considering the various combinations of joints at the four-bar mechanism of the front suspension.

Contact handles, duality, and sutured Floer homology

open access: yes, 2019
We give an explicit construction of the Honda--Kazez--Mati\'c gluing maps in terms of contact handles. We use this to prove a duality result for turning a sutured manifold cobordism around, and to compute the trace in the sutured Floer TQFT. We also show

Study of kerf geometry of multilayers materials in abrasive water jet cutting process

open access: yesMATEC Web of Conferences, 2017
The use of abrasive jet cutting in case of multilayers materials, shows particularities and difficulties, due to different hardness and thickness of layers.

Bis(dicyanamido-κN1)bis[2-(2-hydroxyethyl)pyridine-κ2N,O]nickel(II)

open access: yesActa Crystallographica Section E, 2009
In the title complex, [Ni{N(CN)2}2(C7H9NO)2], the NiII ion (site symmetry overline{1}) adopts a distorted trans-NiO2N4 octahedral geometry. In the crystal, intermolecular O—H...N hydrogen bonds link the molecules, forming a chain along the c ...

Gyrations: The Missing Link Between Classical Mechanics with its Underlying Euclidean Geometry and Relativistic Mechanics with its Underlying Hyperbolic Geometry

open access: yes, 2013
Being neither commutative nor associative, Einstein velocity addition of relativistically admissible velocities gives rise to gyrations. Gyrations, in turn, measure the extent to which Einstein addition deviates from commutativity and from associativity.

trans-Tris(4-bromophenyl)dichloridoantimony(V)

open access: yesActa Crystallographica Section E, 2012
The SbV atom in the title compound, [SbCl2(C6H4Br)3], has an almost regular trigonal–bipyramidal geometry with the equatorial plane made up of three C atoms of the bromophenyl groups and the axial positions occupied by two Cl− ions in

Selection of a common communication link geometry for Saturn, Uranus and Titan [PDF]

open access: yes, 1974
Mission analysis link parametrics, considering a Pioneer baseline, are developed through launch energies, flyby radii, and trip time calculations. Projected is also a 1979 Jupiter Uranus opportunity for a derivative Mariner to fly to Uranus by using the ...

Exponential separation in 4-manifolds

open access: yes, 2000
We use a new geometric construction, grope splitting, to give a sharp bound for separation of surfaces in 4-manifolds. We also describe applications of this technique in link-homotopy theory, and to the problem of locating pi_1-null surfaces in 4 ...

Bis(diisopropylammonium) tetrachloridocuprate(II)

open access: yesActa Crystallographica Section E, 2012
In the title molecular salt, (C6H16N)2[CuCl4], the CuII ion adopts an extremely distorted tetrahedral coordination geometry. All the ammonium H atoms are involved in N—H...Cl hydrogen bonds, which serve to link the cations and anions into ...

Geometric pi Josephson junction: Current-phase relations and critical current

open access: yes, 2009
Josephson junctions with an intrinsic phase shift of pi, so-called pi Josephson junctions, can be realized by a weak link of a d-wave superconductor with an appropriate boundary geometry.
