A reliable iterative method for solving the time-dependent singular Emden-Fowler equations
Tập 3 - Trang 99-105 - 2012
Many problems of physical sciences and engineering are modelled by singular
boundary value problems. In this paper, the variational iteration method (VIM)
is used to study the time-dependent singular Emden-Fowler equations. This method
overcomes the difficulties of singularity behavior. The VIM reveals quite a
number of features over numerical methods that make it helpful for singular and
nonsingu...

Is always high-resolution human model in bioelectromagnetic modeling needed?
Tập 1 - Trang 253-256 - 2011
The paper presents short profile of analytical and numerical methods used in
bioelectromagnetic modeling. Some comparison of different models of human being
was made. Author analyzed it in the following points of view: time of
calculations and technical specifications
Catalogue of maximum crack opening stress for CC(T) specimen assuming large strain condition
Tập 3 - Trang 174-190 - 2013
In this paper, values for the maximum opening crack stress and its distance from
crack tip are determined for various elastic-plastic materials for centre
cracked plate in tension (CC(T) specimen) are presented. Influences of yield
strength, the work-hardening exponent and the crack length on the maximum
opening stress were tested. The author has provided some comments and
suggestions about modell...
Biodiesel production from low cost and renewable feedstock
Tập 3 - Trang 595-605 - 2013
Sustainable biodiesel production should: a) utilize low cost renewable
feedstock; b) utilize energy-efficient, nonconventional heating and mixing
techniques; c) increase net energy benefit of the process; and d) utilize
renewable feedstock/energy sources where possible. In this paper, we discuss the
merits of biodiesel production following these criteria supported by the
experimental results obtai...
Development of a software platform for a plug-in hybrid electric vehicle simulator
Tập 2 - Trang 39-49 - 2011
Electricity use for transportation has had limited applications because of
battery storage range issues, although many recent successful demonstrations of
electric vehicles have been achieved. Renewable biofuels such as biodiesel and
bioethanol also contribute only a small percentage of the overall energy mix for
mobility. Recent advances in hybrid technologies have significantly increased
vehicle...
Constructal design applied to the elastic buckling of thin plates with holes
Tập 3 - Trang 475-483 - 2014
Elastic buckling is an instability phenomenon that can occur if a slender and
thin plate is subjected to axial compression. An important characteristic of the
buckling is that the instability may occur at a stress level that is
substantially lower than the material yield strength. Besides, the presence of
holes in structural plate elements is common. However these perforations cause a
redistributi...
Recent developments and perspectives on the treatment of industrial wastes by mineral carbonation — a review
Tập 3 - Trang 566-584 - 2013
Besides producing a substantial portion of anthropogenic CO2 emissions, the
industrial sector also generates significant quantities of solid residues.
Mineral carbonation of alkaline wastes enables the combination of these two
by-products, increasing the sustainability of industrial activities. On top of
sequestering CO2 in geochemically stable form, mineral carbonation of waste
materials also bri...
Analytical engineering models of high speed normal impact by hard projectiles on metal shields
Tập 3 - Trang 349-373 - 2014
In this review we consider mainly relatively simple engineering models which can
be physically substantiated although usually their justification requires a
large number of assumptions. These models are characterized by the following
features in the case of normal impact: either they determine the relations
between the ”integral characteristics” of penetration (depth of penetration,
ballistic limi...
