Meaningful Research

To achieve airworthiness requirements, 90 second certification test is performed to show compliance. Recent development in the application of computer simulation makes it possible to improve aviation safety through aircraft evacuation simulation. The approach can replace the full scale certification demonstration and has attracted extensive interest. Various evacuation models have been developed to simulate evacuation process. This review investigates the modeling theoretical foundation and summaries individual applications in different scenarios. Moreover, a meaningful research field is proposed for further study.

Research field of migration has been developing for a long time parallel to and outside mainstream institutional academic sociology and its theoretical foundation. In the last two decades, within the field of migration studies, one specific aspect of the phenomena came to the research focus: gender, as significant factor that influences on motivation for migration, shaping, at the same time, its characteristics and specific experiences. With decisive breakthrough of qualitative methods in social sciences and humanities, as well as with gradual development of postmodern philosophy and feminist theory, gender migration studies have been established as research sub-discipline, with its own theoretical and categorical scientific apparatus (as well as institutional-academic grounding), managing more or less successfully to explain and understand multidimensional character of migration processes. This text represents an attempt to make relatively concise overview of disciplines? historical, theoretical and research field development, as a first step in its broader affirmation within Serbian institutional sociology.

Full Scale Testing

The paper presents an overview of a joint project developed among Politecnico di Milano, CSEM and North Sails, aiming at developing a new sail pressure measurement system based on MEMS sensors (an excellent compromise between size, performance, costs and operational conditions) and pressure strips and pads technology. These devices were designed and produced to give differential measurement between the leeward and windward side of the sails. The project has been developed within the Lecco Innovation Hub Sailing Yacht Lab, a 10 m length sailing dynamometer which intend to be the reference contemporary full scale measurement device in the sailing yacht engineering research field, to enhance the insight of sail steady and unsteady aerodynamics [1]. The pressure system is described in details as well as the data acquisition process and system metrological validation is provided; furthermore, some results obtained during a wind tunnel campaign carried out at Politecnico di Milano Wind Tunnel, as a benchmark of the whole measuring system for future full scale application, are reported and discussed in details. Moreover, the system configuration for full scale testing, which is still under development, is also described.

Pave overlay to the freeway repeatedly causes the guardrail’s height lower and lower, which seriously influences its performance in protection and safety. The paper aims to work out a height-adjustable W-beam guardrail which is economic, feasible and safe to solve the shortage in barrier’s height causes from paving overlays by computer simulation tests and full-scale crash tests, which will improve the roadside safety of the guardrail and save the reconstruction cost.

Packaging Technology, Inc. is designing the Mixed Oxide (MOX) Fresh Fuel Package (MFFP) for Duke Cogema Stone & Webster (DCS). The package is unique because of weight and size constraints, having a relatively large payload to package weight ratio. The package has a containment shell, that utilizes high strength stainless steel to optimize the payload relative to the total weight available, protected at the ends by impact limiters. Because of the unique design, full scale prototype impact testing is scheduled for mid-2003. Engineering testing on key design elements, and certification test planning have been completed. Long lead material has been procured for fabrication of the prototype.

Abstract Fundamentals of the similarity theory in the ice deformation mechanics, as well as problems related to scaling up of local ice pressures measured during tests in an ice basin to full scale values are considered. A new scaling principle based on a hypothesis of ice deformation limiting surface isomorphism and direct computer simulation is proposed. An ice-resistant platform, for which local pressures were measured in ice tests and ice pressures were recalculated to full scale values using generated ice deformation limiting surfaces, was considered as an example.

Characteristica Universalis

The disciplinary differentiation of sciences attracted Leibniz’s attention for a long period of time. From nowadays prospects it looks very well grounded as soon as in Leibniz’s manuscripts a modern scholar finds clue ideas of any research field which would tempt him to consider Leibniz as one of the founders of this particular discipline. We argue that this is possible only in retrospection and would significantly distort the essence of Leibniz’s epistemology. Our approach implies, in contrary, the investigation of the Leibniz doctrine of signs on the background of the related philosophical problem, that of expression. The choice of semiotics is justified by the fact that it took a central place in his theoretical constructions, both those of natural sciences and of philosophy. In Leibniz system of knowledge the concept of notes (notae) and sings (signa) served a theoretical foundation of his most important and long-life aspiration to build up practical science of universal characteristics (characteristica universalis). In his eyes this practical science was the science of sciences (Scientia scientiarum), and we can consider it as the matrix for all possible scientific knowledge.
