During the last decade, multihull ships have rapidly evolved into a dominant mode of sea transportation. Their particular area of proliferation is in short sea shipping where they show considerable superiority over competitive designs in attributes such as power requirements, economy, space availability, and sea keeping quality. The rapid growth of the market has led to the need for an expanded range of multihull designs in terms of size, speed, and payload diversity (passengers, vehicles, containers). However, even now there is a scarcity of publicly available preliminary design tools for multihull vessels. This fact hinders the ship owner and naval architect from being able to quickly assess the relative merit of alternative potential designs without having to resort to expensive expert consultancy solutions.

Design Experience

A pilot of a paper-based assessment tool of design skill is presented. The tool is used to assess the development of skills before and after a first year design experience, and before and after a third year multidisciplinary course in design tools and methodology. The tool is an open-ended survey that may be administered quickly and assessed using a simple rubric. Significant improvements were found over the term of the first year course in the areas of problem definition and testing; improvements were observed in the categories of Conceptual Design, Preliminary Design, and Detailed Design in the third year course. Ideas for future improvement are discussed.

Abstract Improvements in computer-aided design tools can significantly increase designer productivity. The ability to explore a variety of possible designs quickly and effectively is essential for a designer. In a previous paper, Goal Directed Geometry (GDG) was introduced as a computational framework for preliminary design, aiding the formulation of engineering models with geometric considerations, and the solution of these models with a multi-objective optimization package. The geometric considerations were limited to static noninterference constraints, introducing a metric and method for prevention of geometric interference between two subassemblies. In this paper, this metric and method are expanded to include the prevention of interference between moving subassemblies, or dynamic interference. Based on a series of repetitive static checks, this metric is intended to be accurate and simple for the designer to use. A case study is presented showing the GDG implementation for a linkage design problem, demonstrating the use of this metric. This parametric GDG model is then solved using an existing optimization program called DSIDES.

The world witnesses a noticeable rapid growth in information technology development of society pertaining to the language of business. One of the remarkable linguistic tools in business communication lies in the form blogs of effective companies. Therefore, the purpose of this paper is to show how effective business context are conducted by the assistance of discourse linguistics related to business. It is obvious that there is a need to concentrate on the cultural meaning relating to the websites’ form and content in the e-commerce context. Research also showed that there is lack of research pertaining to language role and its impact on limitation of websites and blogs. In reviewing literature, according to Forrester Research, most Chinese on-line consumers are convenient with websites involving content in language own use. Further studies and recommendations are presented accordingly.

Sea Transportation

Short Sea Shipping involves the transport of goods and passengers using watercraft over a limited distance and without crossing the ocean. A direct competitor to land transport, it uses ports and inland waterways to complement traditional transport systems to increase capacity, increase flexibility and achieve sustainable transport mobility. The short haul category does not have an official and universally recognized definition. However, several attempts have been made to establish its boundaries and come up with a definition that accurately reflects the content. The definition given by the European Commission: "The movement of goods and passengers by sea between ports located geographically in Europe, or between ports located in non-European countries with coasts on closed seas and bordering Europe" is widely used today. A deep understanding of the serious socio-economic and environmental impacts of road transport operations compels policymakers at different institutional levels (e.g. local, national and regional) to act accordingly and introduce a range of targeted policy frameworks, strategies and interventions to support the broader development and exploitation of others. modes of transport (i.e. rail, inland waterways), thus helping to unload road networks, thus realizing significant improvements in terms of air quality, road safety, and so on. Taking into account the geographic characteristics of the main trading regions of the world, as well as the priorities set by the relevant government authorities, and funds (both public and private) allocated for infrastructure projects, railways, short-distance shipping and inland waterways were considered with a view to establishing additional opportunities to ensure dynamic growth. So, sea transportation over short distances competes with land transport. First of all, they have a geographic advantage, the sea offers more route options and more flexibility for ships. Another benefit concerns economies of scale. Environmental sustainability is the main benefit of short sea shipping. It also has a lower carbon footprint per tonnekilometer than trucks. In addition, maritime transport offers various social benefits. Unloading of road networks is carried out by transferring traffic from land to sea. Ensuring the further development of ports provides for a more detailed study of such a segment as short-distance sea transportation.
