Abstract The objective of this study was to quantify pavement damage due to a conventional (385/65R22.5) and a new generation of wide-base (445/50R22.5) tires using three-dimensional (3D) finite element (FE) analysis. The investigated new generation of wide-base tires has wider treads and greater load-carrying capacity than the conventional wide-base tire. In addition, the contact patch is less sensitive to loading and is especially designed to operate at 690kPa inflation pressure at 121km/hr speed for full load of 151kN tandem axle. The developed FE models simulated the tread sizes and applicable contact pressure for each tread and utilized laboratory-measured pavement material properties. In addition, the models were calibrated and properly validated using field-measured stresses and strains. Comparison was established between the two wide-base tire types and the dual-tire assembly. Results indicated that the 445/50R22.5 wide-base tire would cause more fatigue damage, approximately the same rutting damage and less surface-initiated top-down cracking than the conventional dual-tire assembly. On the other hand, the conventional 385/65R22.5 wide-base tire, which was introduced more than two decades ago, caused the most damage.

Today all structural information of the lung can be quantified and interpreted in the three-dimensional space of real-world biology. Remarkable achievements in the theory and practice of biological stereology are creating a new generation of data suitable for constructing structural hierarchies. Such hierarchies serve to organize and link biological data, thereby providing a framework on which to build new information systems. In this review, we describe the new tools of quantitative morphology and show how they can be used to design new experiments for lung research.

Fats as complex mixtures of acylglycerols with lipid and non-lipid substances are an integral part of human nutrition. The presence of acylglycerols of trans-isomers of fatty acids causes many cardiovascular diseases and metabolic disorders. A promising approach to solving the problem of minimizing the content of these undesirable compounds in food recipes is to create a new generation of fat systems, oleogels, which are the subject of this study. High-oleic sunflower oil was used as a dispersion medium of oleogels, which allows obtaining systems with increased resistance to oxidation, as opposed to the oils of traditional kinds. Sunflower seed wax and tocopherols are chosen as a dispersed phase of these fatty systems. The choice of these components was based on their properties to create a three-dimensional structure in oleogels with specified thermomechanical characteristics. Currently, there is a lack of information on the influence of the content of the dispersed phase on the technological parameters of oleogels, namely oxidative resistance and sorption properties. The purpose of the presented work was to study these features of oleogels and establish their dependences on their composition. To solve this problem, the yield surface method is used in the work. The unknown values of the parameter vector were determined by using regression analysis algorithms. Deviation functionality was minimized by finding the appropriate combinations of the experimental series of predictors. A mathematical model was developed which allows predicting oxidative stability and sorption properties of oleogels based on the data on their composition. The suitable mass fractions of the components of the dispersed phase of oleogels have been determined as follows: tocopherol content is 0.10–0.14 wt.% and the sunflower seed wax content is 1.8–4.0 wt.%. The results obtained can serve as a scientific basis for the development of technology for the industrial production of oleogels as new generation fatty systems.

Abstract At present, the tissue paper manufacturing is mostly based on the dry crepe technology. During the last decade, the manufacturers have introduced new tissue machines concepts that increase the softness, bulk, and absorption capacity. Such machines produce a strong regular three-dimensional (3D) structure to the sheet before the Yankee cylinder. At present, the quality of the 3D structure is not evaluated, or it is evaluated only subjectively at the mill. This is mostly because of the difficulties to separate reliably the regular 3D pattern from other variations. This paper introduces a frequency analysis based method which separates the surface profile variances in tissue paper to the creping, to the regular 3D pattern and to the residual variation. The 3D surface profiles and their variances were determined online with the photometric stereo method. We show that the introduced analysis method evaluates the variance portions reliably and the results are consistent with the visual perception of the 3D surfaces. In one particular product, the regular 3D pattern explains 74 % of total surface variance; the creping explains 10 % and residual variations 16 %. Furthermore, the creping and residual variances are quite stable over time whereas the variance of the regular 3D pattern fluctuates significantly.

Abstract This paper gives an overview of an integrated and intelligent database system for a plant engineering framework. We have integrated existing two-dimensional (2D) CAD systems, a three-dimensional (3D) CAD system, and a relational database system which stores engineering information such as design conditions, maintenance histories, and inherent properties. By integrating these systems, the infrastructure for concurrent engineering has been realized. As for design knowledge, we treat object-oriented programming as a useful knowledge representation method. We analyze the plant structure and functional requirements of the system, and then represented them by using the hierarchical Class structure. Design knowledge accompanies the Class, so we represent it using Method. As a design automation system, we develop an automated design check system. This is implemented by using the Common Lisp Object System. These systems are the main parts of the plant engineering framework, and are utilized in the practical design. We intend to develop a mechanical/electronic design framework using the same approach.

Connecting heterogeneous databases through the World Wide Web (WWW) is crucial for most business organizations. The underlying complex problem is the handling of heterogeneity and communication between different data repositories (or database systems). Such interoperability is crucial as it enables the integration of business processes across different business organizations, and therefore becomes a key issue within the new generation of Web-based business applications (called Web Services). CORBA (Common Object Request Broker Architecture) provides protocols and components that allow interoperability between different software platforms (Tari & Bukhres, 2001), such as C++ and Java. However, CORBA does not deal with WWW-based interoperability. In this paper we propose an extension of one of the core elements of CORBA, called Portable Object Adapter (POA), to deal with persistency of business information. The proposed extension, called CODAR, manages the whole life cycle of persistent objects, including activation, deactivation, instantiation, and deletion. At the end of this paper we describe an extension of CODAR to deal with performance by including advanced caching and prefetching techniques.

The Relationship

A new generation electric high-speed train called Aerotrain has levitation wings and levitates under Wing-in-Ground (WIG) effect along a U-shaped guideway. The previous study found that lacking knowledge of the design makes the prototype unable to regain stability when losing control. In this paper, the nonlinear three-dimensional dynamic model of the Aerotrain based on the rigid body model has been developed to investigate the relationship between the vehicle body design and its stability. Based on the dynamic model, this paper considered an Aerotrain with a horizontal tail and a vertical tail. To evaluate the stability, the location and area of these tails were parameterized. The effects of these parameters on the longitudinal and directional stability have been investigated to show that: the horizontal tail gives its best performance if the tail area is a function of the tail location; the larger vertical tail area and (or) the farther vertical tail location will give better directional stability. As for the lateral stability, a dihedral front levitation wing design was investigated. This design did not show its effectiveness, therefore a control system is needed. The obtained results are useful for the optimization studies on Aerotrain design as well as developing experimental prototypes.
