Abstract geometrical computation involves drawing colored line segments (traces of signals) according to rules: signals with similar color are parallel and when they intersect, they are replaced according to their colors. Time and space are continuous and accumulations can be devised to unlimitedly accelerate a computation and provide, in a finite duration, exact analog values as limits. In the...

The title compound, C(25)H(30)O(12), which demonstrates a significant hepatoprotective effect, has comparable geometrical parameters to those of similar compounds. The absolute configuration of the title compound, viz. 2R,3S, was identified from the Flack parameter of 0.05 (17) and the Hooft parameter of 0.04 (6).

Multilevel spiral inductors are viable means to achieve enhanced inductance when designing in a multiple metallization level environment, as is typical of processes used for fabrication of RFICs. In this paper, analyses and design considerations are discussed for several spiral structures implemented in CMOS and BiCMOS technologies. Design issues considered include the performance effects of ge...

Elasticity is viewed here as a starting point in the description of inelastic behavior. The two-scale geometry provided by structured deformations and a field theory of elastic bodies undergoing disarrangements (non-smooth geometrical changes) and dissipation are used to formulate and illustrate a concept of ”submacroscopically stable configuration.” A body in a submacroscopically stable equili...

This work analyzes the influence of the discretization error contained in the Finite Element (FE) analyses of each design configuration proposed by structural shape optimization algorithms over the behaviour of the algorithm. If the FE analyses are not accurate enough, the final solution will neither be optimal nor satisfy the constraints. The need for the use of adaptive FE analysis techniques...

The crystal structure of [Ni(NO)(η5-Cp*)] in the light-induced metastable state was determined by X-ray diffraction at 25 K of a crystal with a 47% metastable-state population. The most significant geometrical change is the formation of a side (η2) bound structure with an Ni-N-O angle of 92(1)°, compared with 179.2(2)° in the most stable configuration, and a corresponding Ni-O distance of 2.09 ...

A s serial robots parallel manipulator may be in a singular configuration. In these configurations the inverse jacobian matrix is singular and the end-effector may move although the articular velocities are equal to zero. The determination of the loci of these singular configurations is an important problem because in such configuration the articular forces may go to infinity and yield importan...

Nowadays, the application of floating breakwaters in small or recreational harbors has found more popularity. These types of breakwaters are more flexible in terms of design, configuration and especially installation compared with fixed breakwaters. In the current study, the performance of floating breakwater (FBs) under regular waves was studied using the physical modeling method. For the mode...

We propose the time-dependent generalization of an ‘ordinary’ autonomous human biomechanics, in which total mechanical + biochemical energy is not conserved. We introduce a general framework for time-dependent biomechanics in terms of jet manifolds derived from the extended musculo-skeletal configuration manifold. The corresponding Riemannian geometrical evolution follows the Ricci flow diffusi...
