IMO MSC circular 1033 [1] outlines the guidelines for evacuation analyses of new and existing passenger ships. This requirement coupled with recent advancements in computer technology has lead to the development of sophisticated computer-based simulation of the evacuation process on passenger ships. In order for these simulation tools to provide accurate and useful results, it is imperative they use realistic data for passenger movement throughout the evacuation process. However, due to the nature of ship abandonment, quantifying human performance in actual abandonment situations is very difficult. For this reason, simulation inputs must rely on results of controlled, well-defined experiments. This paper outlines experiments conducted to quantify human performance during abandonment using a variety of life saving appliances for ambulatory and non-ambulatory individuals wearing personal floatation apparatus. Evacuation analysis using commercially available software with these data is also presented as it relates to improving ship design for evacuation of non-ambulatory persons.

Evacuation Routes

The ro-ro passenger ship is a type of passenger ship which is commonly seen in Europe. After the tragedy of MV Estonia, an effective evaluation of escape routes in passenger ship in the initial stage of ship design has been required by International Convention for the Safety of Life at Sea (SOLAS) Convention. To reduce the loss of life in passenger ships at sea, the International Maritime Organization (IMO) has created the revised guidelines on evacuation analyses for new and existing passenger ships. This article followed IMO's mandatory guidelines via using the hydraulic model of emergency egress to scrutinize the evacuation routes, congestion points, and the total evacuation duration of MV Tai Hwa.

The new SOLAS regulations II-1/8-1, II-2/21 and II-2/22 on safe return to port are introduced; it is demonstrated how the regulations will influence the design of future passenger ships. The requirements on safe areas and on propulsion system layout are discussed with the aid of examples. A software tool supporting the safe return to port assessment is proposed. The tool will assess the degraded performance of essential systems for all relevant casualty cases.

System Designs

For many years the complexity of submarine design has required the construction of full-scale mockups to integrate the system designs, plan the construction, and verify the operability. In the late 1980's, computer technology evolved to allow ship design to be accomplished by developing comprehensive mathematical models of the ship's arrangement. Imaging of these models creates a virtual reality of the ship's interior. This paper explores the features of this technology that emulate the function of the physical mockup, discusses experience to date in the SEAWOLF design at Newport News Shipbuilding in applying CAD technology as a mockup alternative, and looks to the opportunities that are available in the near term.

In the early stages of ship design a considerable amount of experience and knowledge is used to build and evaluate empirical models with known design relationships. However, computer-based systems which aim to assist this stage have tended to concentrate on the analytical aspects of the process and have not been successful in integrating with this expertise and benefitting from it. This paper presents some of the results of a program of research into methods and representing knowledge of empirical numerical relationships used in these early stages of the design process. The work is based on an experimental system, DESIGNER, described in earlier papers. The DESIGNER system is used to carry out a series of evaluations of design sessions, using a warship design model. By examining the progress toward a set of design goals and the classes of interactions used, an improved understanding of the requirements of an interactive numerical design system is developed. As a consequence, methods have been developed to handle approximate values and relationships, to include design margins, and to represent explicitly in the system the definition and use of goals, or design requirements. Using a design model representing a bulk carrier, the paper then presents a worked example to illustrate the use of the new numerical knowledge techniques. It is concluded that the techniques could make a useful contribution to any interactive numerical design system which aims to provide improved use of expertise.

Fibrotic Lung Disease

In patients with idiopathic pulmonary fibrosis (IPF), there is an urgent need of biomarkers which can predict disease behaviour or response to treatment. Most published studies report results based on continuous data which can be difficult to apply to individual patients in clinical practice. Having antifibrotic therapies makes it even more important that we can accurately diagnose and prognosticate in IPF patients. Advances in computer technology over the past decade have provided computer-based methods for objectively quantifying fibrotic lung disease on high-resolution CT of the chest with greater strength than visual CT analysis scores. These computer-based methods and, more recently, the arrival of deep learning-based image analysis might provide a response to these unsolved problems. The purpose of this commentary is to provide insights into the problems associated with visual interpretation of HRCT, describe of the current technologies used to provide quantification of disease on HRCT and prognostication in IPF patients, discuss challenges to the implementation of this technology and future directions.

The design of engineering systems involves the design of dependent subsystems and the integration of these into a whole. A typical system has the characteristics of being multileveled, multidimensional, and multidisciplined in nature. It is this complexity which causes problems for the designer in making well-founded decisions. A decision support technique has been developed which offers a structured facility for the design of the subsystems and for the modeling of the interaction which is present between subsystems. The method, employing optimization procedures, allows all aspects of the system design to be considered concurrently, to produce the "best" solution, as defined by the specifications. This is in contrast to the traditional design method, which is iterative and cyclic in nature, involving sequential reevaluation and refinement. In this paper, the effectiveness and efficiency of the decision support problem approach is demonstrated using the hierarchical characteristics of a design for a barge. The barge problem, though basic in form, is comprehensive in concept and tutorial in nature. As a formulation for "system" optimization, it uses a computer-based method for solution and illustrates the virtues of a multilevel/multidisciplinary approach to design and decision-making. It also exhibits the same characteristics and provides valuable insight into the solution of the more complex problems encountered in practical ship design.

The 1960S

Online catalogs are types of interactive computer systems; they can also be called “interactive catalogs” because a user interacts with the computer to find relevant information. The interaction is the main difference between Online Public Access Catalogs (OPACs) and other types of library catalogs (Hildreth, 1982; Matthews, 1985). Online catalogs are regarded as real-time interactive retrieval systems for libraries (Fayen, 1983). According to Peters (1991), the development of online catalogs can be characterized by three decades of development. In the 1960s, the development of online catalogs was led by the development of computer technology and the library community’s desire to increase efficiency in finding library materials. In the 1970s, commercial vendors started to replace large university libraries as the principal developers of computer-based library systems. In the 1980s, local libraries expand their control of the library catalog systems.

One of the worst problem in Bojonegoro is flood. This research aims to know the factor that could become the factor of flood in Bojonegoro. Besides that, this research analyses the planning of transportation river design in Bojonegoro. Flood discharge analysis uses Nakayasu synthesis unit hydrograph for period of 5 years, 10 years, 25 years, 50 years, and 100 years, then they would be compared to the water maximum capacity that could be loaded by the river. According to the analysis result, Bengawan Solo River in Bojonegoro could not able to load flood discharge from Nakayasu synthesis unit hydrograph analysis for all periods. The result conclusion that captured by HEC-RAS application has the same idea. It shows flood water surface is more than full bank capacity elevation. For river transportation design planning, according to analysis of parameter of depth, width for one and two lanes, turning basin and its depth, the ship design that recommended to ship in the Bengawan Solo River in Bojonegoro are cargo ship and passenger ship with draft of 0.6 m and LOA of 18 m, or the capacity of a passenger ship is 70 people.
