Free Vibrations of Foundation Beams on Two-Parameter Elastic Soil
No full textA finite element free vibration analysis of beams on a two-parameter elastic foundation is performed using the exact shape functions. The stiffness matrix and the mass matrix are deduced in closed form for the whole parameter range. Numerical comparisons and examples allow us to check the performance of the proposed finite element. A practical example ends the pape
Static analysis of a Bickford beam by means of the Differential Quadrature Element Method

No full textA modified quadrature element method to perform static analysis of structures
No full textIn this paper, an improved version of the quadrature element method (QEM) is proposed. By means of
a careful distribution of sampling points, the proposed method overcomes the drawback of the distance of the QEM without introducing further degrees of freedom at the ends of the element as in the di4erential quadrature element method (DQEM). The aim of the paper is to show the potentialities of this modied quadrature element method (MQEM) for several structural examples
DQ solutions of a vibrating membrane model: an error analysis
No full textIn order to investigate the possible application of the quadrature rules to a problem in the three-dimensional space-time domain, an error analysis is here performed. Some considerations about the error function confirm the conditional stability of the method and the necessity of a suitable distribution to contain the errors
Adjoint divisors on algebraic curves
No full textAbstractLet C be a numerically connected curve lying on a smooth algebraic surface. We show that if A is an ample invertible sheaf satisfying some technical numerical hypotheses then ωC⊗A is normally generated. As a corollary we show that the sheaf ωC⊗2 on a numerically connected curve C of arithmetic genus pa⩾3 is normally generated if ωC is ample and does not exist a subcurve B⊂C such that pa(B)=1=B(C−B)
The Impact of Augmented Reality Devices on Operator Performance in Manufacturing Contexts
No full textThis study explores the impact of augmented reality (AR) on worker performance in manufacturing contexts through an analysis of case studies extant in the literature. Two specific analyses were conducted to assess the impacts of AR technologies on worker performance in terms of objective and subjective metrics, and in terms of their age, experience with the task and experience with the AR device. Regarding objective metrics, the results showed that the task completion time was reduced for some AR devices (projectors, monitors, tablets, smartphones), whereas the use of the head-mounted display (HMD) increased task-completion time; moreover, the error rate was reduced with any AR device compared with traditional methods. Regarding subjective metrics, the analysis underlined that operator perceived a lower workload with the HMD or the monitor compared with traditional methods. The age of operators did not influence performance, while the operators' experience allowed for the improvement of human performance
On the canonical ring of curves and surfaces
No full textLet C be a curve (possibly non reduced or reducible) lying on a smooth algebraic
surface. We show that the canonical ring R(C, ωC) is generated in degree 1 if C is numerically four-connected, not hyperelliptic and even (i.e. with ω_C of even degree on every component).
As a corollary we show that on a smooth algebraic
surface of general type with pg(S) ≥ 1 and q(S) = 0 the canonical ring R(S, KS) is generated
in degree ≤ 3 if there exists a curve C ∈ |KS| numerically three-connected and not hyperelliptic
