Multi-ply Sheet formation for woodfree paper (Multijet head box), economy and technical feasibility.

open access: yesJAPAN TAPPI JOURNAL, 1994
The equipment which produces three-ply woodfree paper can be installed nowadays by using the established technical methods. This concept is significant only when the printability of outer plies is better than that of inner ply and the cost of material for inner ply is obviously cheaper than that for outer plies.

Strain measurements of composite laminates with embedded fibre Bragg gratings : criticism and opportunities for research [PDF]

open access: yes, 2010
Embedded optical fibre sensors are considered for structural health monitoring purposes in numerous applications. In fibre reinforced plastics, embedded fibre Bragg gratings are found to be one of the most popular and reliable solutions for strain ...

Dynamic behavior of a rotating delaminated composite beam including rotary inertia and shear deformation effects [PDF]

open access: yes, 2015
A finite element (FE) model is developed to study the free vibration of a rotating laminated composite beam with a single delamination. The rotary inertia and shear deformation effects, as well as the bending–extension, bending–twist and extension–twist ...

A family of higher-order single layer plate models meeting $C^0_z$ -- requirements for arbitrary laminates [PDF]

open access: yes, 2019
In the framework of displacement-based equivalent single layer (ESL) plate theories for laminates, this paper presents a generic and automatic method to extend a basis higher-order shear deformation theory (polynomial, trigonometric, hyperbolic, ...) to ...

Distributed Gaussian Processes [PDF]

open access: yes, 2015
To scale Gaussian processes (GPs) to large data sets we introduce the robust Bayesian Committee Machine (rBCM), a practical and scalable product-of-experts model for large-scale distributed GP regression. Unlike state-of-the-art sparse GP approximations,

Analysis of laminated doubly-curved shells by alayerwise theory and radial basis functions collocation, accounting for through-the-thickness deformations

open access: yes, 2011
In this paper, the static and free vibration analysis of laminated shells is performed by radial basis functions collocation, according to a sinusoidal shear deformation theory (SSDT).

A sub-1-V Bandgap Voltage Reference in 32nm FinFET Technology [PDF]

open access: yes, 2009
The bulk CMOS technology is expected to scale down to about 32nm node and likely the successor would be the FinFET. The FinFET is an ultra-thin body multi-gate MOS transistor with among other characteristics a much higher voltage gain compared to a ...

From Fabric to Fiber: A Study on the Use of Cotton Textile Waste in Papermaking

open access: yesJournal of Natural Fibers
Currently, recycling fibrous materials has become a key challenge in sustainable waste management. The presented research investigates the potential use of waste cotton fibers from the textile industry as an additive to kraft pulp used in paper ...

Mars Science Helicopter Conceptual Design [PDF]

open access: yes, 2020
Robotic planetary aerial vehicles increase the range of terrain that can be examined, compared to traditional landers and rovers, and have more near-surface capability than orbiters. Aerial mobility is a promising possibility for planetary exploration as
