Based on mechanisms

In this paper, authors use a fi nite element model based on higher-order displacement plate theory for analysis of stiffened laminated composite plates. Transverse shear deformation is included in the formulation making the model applicable for both moderately t hick and t hin composite plates.

The following report was prepared immediately after the writer's return from the conference. It was written from the viewpoint of an engineer listening to experts in a field far separated from his own. Such judgments as may be found interspersed amongst the reports of individual papers are of an engineering nature, and are not to be construed, as being based upon other than an amateur’s knowledge of linguistic theory.

This paper presents an experimental preference tool des!gned, implemented and tested m the Eurotra pro)ect. The mechanism is based on preference rules which can either compare subtrees pairwise or single out a subtree on the basis of some specified constraints. Scoring permits combining the effects of various preference rules.

This paper presents a high precision bonding approach, capable of submicron alignment accuracy, based on the thermosonic flip-chip bonding technique and misalignment self-correction elements. The precision of the bonding technique is guaranteed by using of misalignment self-correction bump (convex) and hollow (concave) elements.

In this paper, an optimized homogenization method using uniaxial tensile tests to estimate material parameters in the micromechanical model of a heat treated DC04 steel is introduced. The method is based on a representative element model for the macroscopically homogeneous material.

The paper presents a numerical method to simulate two-phase turbulent cavitating flows in ducts of varying cross-section usually faced in engineering. The method is based on solution of two-phase Reynolds-averaged Navier-Stokes equations of two-phase mixture. The numerical method uses artificial compressibility algorithm extended to unsteady flows with dual-time technique.

In this paper, the buckling and post-buckling behaviors of eccentrically stiffened functionally graded material (ES-FGM) plates on elastic foundations subjected to in-plane compressive loads or thermal loads are investigated by an analytical solution. The novelty of this work is that FGM plates are reinforced by FGM stiffeners and the temperature, stiffener, foundation are considered. The first-order shear deformation plate theory is used.

In this paper, the free vibration of functionally sandwich grades plates with stiffeners is investigated by using the finite element method. The material properties are assumed to be graded in the thickness direction by a power-law distribution. Based on the third-order shear deformation theory, the governing equations of motion are derived from the Hamilton’s principle.

In the paper a technique for determining the coefficients of the linearized equivalent equation based on the Fokker-Piank equation approach is presented. The investigation is then applied to Duffing and Vanderpol oscillations under a zero mean Gaussian white noise.

The third book of four-volume edition of “Solar Cells” is devoted to solar cells based on silicon wafers, i.e., the main material used in today's photovoltaics. Single-crystalline Si (c-Si) modules are among the most efficient but at the same time the most expensive since they require the highest purity silicon and involve a lot of stages of complicated processes in their manufacture. Polycrystalline silicon (mc-Si) cells are less expensive to produce solar cells but are less efficient.

One of the most fundamental question that an Engineer has to ask him/herself is what is how does it deform, and when does it break. Ultimately, it its the answer to those two questions which would provide us with not only a proper safety assesment of a structure, but also how to properly design it. Ironically, botht he ACI and the AISC codes are based on limit state design, yet practically all design analyses are linear and elastic.

In the latest years graphene based research has witnessed a tremendous explosion. This two dimensional ‘‘dream’’ material has come into the main spotlight of fundamental and applied research in diverse nano-science fields, but surprisingly rapidly, it has also attracted the interest of major stakeholders in the private sector.

For writers of technical books, there can be no better piece of advice. Around the time of writing the first edition – about a decade ago – there were very few monographs on this subject: today, there are possibly no less than 20. Based on critical inputs, this edition stands thoroughly revamped. New chapters on ventilator waveforms, airway humidification, and aerosol therapy in the ICU now find a place. Novel software-based modes of ventilation have been included. Ventilator-associated pneumonia has been separated into a new chapter.

Private real estate investment is a typical one-shot decision problem for personal investors due to the huge investment expense and the fear of substantial loss. There is only one outcome for a one-shot decision problem. The private real estate investment problem is analyzed within a one-shot decision framework. The procedure for a one-shot decision consists of two steps. In the first step, for each alternative, some states of nature, which are called focus points, are selected amongst all states of nature based on the attitudes of decision makers on uncertainty.

There are two general decision making strategies that judges use when evaluating a beer. In a top-down decision making strategy, the judge forms an overall impression about the quality of the beer, decides what overall score to assign that beer, and deducts points for each deficient characteristic of the beer based on the overall impression. The problem with this top-down approach to beer evaluation is that it is difficult to ensure that the points allocated to each subcategory (e.g.
