In this paper, the mode III crack problem of a non-homogenous layer bonded to an elastic half-plane is considered. It is assumed that the half plane is homogeneous and the layer is non-homogeneous in which the elastic properties are continuous throughout the layer. The ...

Thoughtfully-chosen, properly-designed new construction can significantly improve both the resilience to natural and man-induced disasters and the long-term sustainability of modern urban environments in the 21st century. In particular, precast/prestressed concrete cons...

The use of Autonomous Underwater Vehicles (AUVs) is now widespread among the underwater observation and survey. Because AUVs are not restricted by an umbilical cable, we think that AUVs have the most suitable form to collect ocean data or work depending on subjects of s...

Abstract The cost of road construction and expenditures on the maintenance of pavements, i.e., their whole life cost, represents a lot of money. The paper describes a procedure for a pavement management system with degradation models and estimates the length of time fo...

In the present work, a numerical method to solve the problem of free convec-tion in enclosures with complex geometries is developed. This development isexecuted by the combination of projection and Galerkin nite element methods.Nine-node (quadratic) quadrilateral elemen...

Modal analysis is the process of determination of the natural frequencies and mode shapes of structures. In practical problems, modal analysis may be repeated many times, which results in a huge amount of computations. Although parallel processing technique can reduce t...

The permits governing longer combination vehicle (LCV) activity in Canada aim to leverage LCV productivity advantages relative to other truck configurations while subjecting LCV operations to stringent regulatory controls. As of 2016, nine of the 13 provinces and terri...

This paper presents a neural network controller for reducing ship's roll motion using active-fin stabilizers. Classical PID controllers fail to control the ship's roll when dynamic parameters of ship change. An innovative approach was used to overcome this disadvantage ...

Flow of gas in pipelines is subject to thermodynamic conditions which produces two-phase bulks (i.e., slugs) within the axial pipeline flow. These moving slugs apply a moving load on the free spanning pipe sections, which consequently undergo variable bending stresses, ...

Piezoelectric resonators are widely applied in frequency control components in electronic devices, digital computers, and telecommunication. The stability of these resonators are affected by force-frequency and temperature-frequency effects. In this paper, a simple labo...

In this study, the response phase of the management of natural disasters is investigated. One of the important issues in this phase is determining the distribution areas and timely distribution of relief to affected areas in which transportation routing is of a critical...

Abstract The bridge over the Timis River in Albina, assures the connection between the city of Timisoara and Lugoj through the city of Buzias, facilitating the access to the county capital for the inhabitants of this area. Due to the important economical development of ...

These days, steel slag is one of big problem in Vietnam because there are too much steel slag produced from steel industries, especially electric-arc furnace slag. In order to use this by-product in highway, especially in hot mix asphalt, the main objective of this pape...

Czas przeprowadzania pomiarów wyrywkowych (okres w roku i dobie) determinuje dokładność szacowania poziomu hałasu. Dlatego też istnieje konieczność określenia ujednoliconych procedur wyznaczania miarodajnych wartości parametrów ruchu do obliczeń LpAeq w szczególności w ...

Harbors are important infrastructures for an offshore production chain. These harbors are protected from the actions of sea by breakwaters to ensure safe loading, unloading of vessels and also to protect the infrastructure. In current literature, research regarding the ...

In this work, the human lung alveoli are idealized by a three dimensional honeycomb like geometry and a fluid-structure analysis is performed to study the normal breathing mechanics. In contrast to previous works in which the inlet flow rate is predened, in this model, ...

As oil or gas field moves deeper offshore area, offshore offloading operations such as Tandem or Side-by-Side arrangement between two floating structures take place in many locations throughout the world and also have many hydrodynamic problems. Therefore, the researche...

Road Safety Audits (RSAs) include an independent review process that has increasingly been incorporated into the Design-Build-Operate model for (typically) large-scale freeway construction projects throughout Canada. While recent research has suggested that RSAs are a c...

International audience; Subspace algorithms based on higher-order cumulants were developed to achieve high-resolution separation in non-Gaussian processes. However, singular value decomposition (SVD) of a huge matrix is an unavoidable step of these algorithms. The memor...

Relatively new concepts such as concurrent engineering (CE) and set-based design (SBD) are being actively pursued by the US Navy to advance a paradigm shift in designing the next generation fleet of surface combatants. Collective work is ongoing toward developing a comp...
