Ship ballasting and de-ballasting are critical to a ship’s stability, and a major part of ship and port operations. Here, we examine the current procedures and potential issues that can arise when a quick turnaround in port is required. Through time-based modeling of the ship’s systems, new methods were used to analyze the feasibility of each scenario as well as ensure the systems were operating optimally. After rigorous testing, a new approach was developed to decrease time in port, increase system reliability/safety, and improve overall efficiency. Paper published with permission.

This article is founded on the basic assumption that Europe taken as a whole possesses all the necessary resources to combat successfully any non-European competitor in the fields of technology, provided that it solves the management problem of organizing the coordination of those resources. At present, the author argues, they are dispersed and so underexploited. To contribute to the solution of this core problem, he sets out a new approach to research collaboration, using the example of the German–French Institute for Automation and Robotics to show ways in which HEIs can cooperate internationally to provide industry with what it needs to be truly competitive.

We introduce here a new approach to the study of $m$-quasi-invariants. This approach consists in representing $m$-quasi-invariants as $N^{tuples}$ of invariants. Then conditions are sought which characterize such $N^{tuples}$. We study here the case of $S_3$ $m$-quasi-invariants. This leads to an interesting free module of triplets of polynomials in the elementary symmetric functions $e_1,e_2,e_3$ which explains certain observed properties of $S_3$ $m$-quasi-invariants. We also use basic results on finitely generated graded algebras to derive some general facts about regular sequences of $S_n$ $m$-quasi-invariants

Tooth Type

New methods to estimate both the rock strength and tooth wear while drilling with roller-bits were developed and proposed in Part 1. These methods were derived from the results of drilling tests using milled-tooth type three-cone bits with different amounts of tooth wear. In this report, these methods were extended and applied to insert type three-cone bits. The validity of the test and data analyses techniques of Part 1 were confirmed for insert bits. The methods to estimate the tooth wear proposed in Part 1 were based on the drillability strength of rock. A new approach to determine the tooth wear is presented. This new approach could be more readily applied to evaluating tooth wear when compared to the previous methods based on the drillability strength of rock.

Area Data

The Census Bureau has announced new methods for disclosure control in public use data products. The new approach, known as differential privacy, represents a radical departure from current practice. In its pure form, differential privacy techniques may make the release of useful microdata impossible and limit the utility of tabular small-area data. Adoption of differential privacy will have far-reaching consequences for research. It is likely that scientists, planners, and the public will lose the free access we have enjoyed for six decades to reliable public Census Bureau data describing US social and economic change.

In recent years, eighteenth-century actors' portraits have deservedly received growing attention from both art and theatre historians. For its extent, variety and quality, for its social and aesthetic implications, eighteenth-century theatrical portraiture demands a refined theoretical approach: it has helped to create an interdisciplinary field where new methods in dealing with theatre iconography have been profitably deployed. English and American scholars have contributed to develop this field in a specific way, devoting single studies and monographs to portraits of actors. In spite of the importance of French theatrical portraiture, French contributions are less significant. In most cases theatrical portraits are considered exclusively by art historians, and in the context of catalogues or monographs on a single painter. In France the stage portrait is often undervalued: it is relegated to a pictorial genre considered as inferior (tableaux de théâtre), or it is thought to derive from a disreputable theatricalization of history painting; in any case there has been a real difficulty in submitting these images to critical and specific investigation. In short, even if a new approach to theatrical iconography prevails over the strict utilitarianism of the theatre historians, who—in the best cases—sought in actors' portraits only documentary evidence of acting practice, costume or set design, more work has to be done by art historians, to accord theatrical images the independent status of an iconographic text.

Aircraft Conceptual Design

Nowadays, all the stakeholders, policy makers, regulators, aircraft designers, producers, operators, etc.) are intensively working on development of the aircraft with full electric and hybrid propulsion systems. However, the technical, technological constrains (like limit on accumulator energy density) require introducing a new approach to conceptual design of such aircraft. The new methods is based on energy and mass balance evaluation. This paper analyses the identified constrains; integrates the energy and mass balance equations into the preliminary definition and calculations of the aircraft performance. By this way, the technological constrains might be transferred into the limitation on the aircraft energy and mass breakdown, that initiates a new approach to aircraft conceptual design uses the knowledge based multidisciplinary optimization. The paper describes the developed methodology for conceptual design of aircraft. It show results of implementing this new development philosophy to conceptual design of a four-seat small electric/hybrid aircraft and a special hybrid cargo UAV. The discussion of the results including got by using the emerging and enabling new technologies and new methods and solutions (including for example distributed propulsion system, unconventional forms, morphing, biomimics, etc.), demonstrates the possible implementation of the new development philosophy, new approach to aircraft conceptual design.
