Increasing demands on user interface (UI) usability, adaptability, and dynamic behavior drives ever-growing development and maintenance complexity. Traditional UI design techniques result in complex descriptions for data presentations with significant information restatement. In addition, multiple concerns in UI development leads to descriptions that exhibit concern tangling, which results in high fragment replication. Concern-separating approaches address these issues; however, they fail to maintain the separation of concerns for execution tasks like rendering or UI delivery to clients. During the rendering process at the server side, the separation collapses into entangled concerns that are provided to clients. Such client-side entanglement may seem inconsequential since the clients are simply displaying what is sent to them; however, such entanglement compromises client performance as it results in problems such as replication, fragment granularity ill-suited for effective caching, etc. This paper considers advantages brought by concern-separation from both perspectives. It proposes extension to the aspect-oriented UI design with distributed concern delivery (DCD) for client-server applications. Such an extension lessens the serverside involvement in UI assembly and reduces the fragment replication in provided UI descriptions. The server provides clients with individual UI concerns, and they become partially responsible for the UI assembly. This change increases client-side concern reuse and extends caching opportunities, reducing the volume of transmitted information between client and server to improve UI responsiveness and performance. The underlying aspect-oriented UI design automates the server-side derivation of concerns related to data presentations adapted to runtime context, security, conditions, etc. Evaluation of the approach is considered in a case study applying DCD to an existing, production web application. Our results demonstrate decreased volumes of UI descriptions assembled by the server-side and extended client-side caching abilities, reducing required data/fragment transmission, which improves UI responsiveness. Furthermore, we evaluate the potential benefits of DCD integration implications in selected UI frameworks.

This paper focuses on mariner-ship interaction from the practical end of the design spectrum. Statistical data on marine collisions, rammings and groundings attribute a considerable percentage of marine casualties to poor ship controllability. A vessel's controllability is of a dichotomous nature, constrained not only by its inherent controllability characteristics, fixed by the naval architect, but also by the skill and the expertise of the shiphandler in initiating a conclusive control strategy. The results of an international survey of naval architects and shiphandlers are presented. The techniques of frequency distribution and factor analysis were used to identify the key ship controllability effectors. This survey highlights where improvements in terms of interface design can be made. The survey identifies the key controllability effectors of naval architects and ship-handlers for effective mariner-ship interaction. A case study is presented which identifies the applicability of part-task ship simulation to improve confidence levels in practical ship control. For effective mariner/ship interaction, the designers of ships must use the various codes of practice for a ship's bridge in order to improve the bridge as a control station, and marine licensing authorities have to realize the potential benefits that training with computerized ship simulation can bring the industry.

Characteristics Analysis

In conceptual mechanical design process, designers sometimes focus their attentions on mapping a sub-function or functional unit to a single mechanism or system, and ignore the interfaces among the structural elements. This paper first summarized the behavioral characteristic of the interfaces in energy, mechanics, kinematics by analyzing the roles, classification and connection styles of such interfaces. Subsequently, it introduced the concepts of function and free surface, and gave the interface design process. Finally, a case study was conducted to demonstrate the feasibility of the proposed methodologies.
