Development of a simple model for batch and boundary information updation for a similar ship’s block model

In early 2000,large domestic shipyards introduced shipbuilding 3D computer-aided design (CAD) to the hull production design process to define manufacturing and assembly information.The production design process accounts for most of the man-hours (M/H) of the entire design process and is closely connected to yard production because designs must take into account the production schedule of the shipyard,the current state of the dock needed to mount the ship’s block,and supply information.Therefore,many shipyards are investigating the complete automation of the production design process to reduce the M/H for designers.However,these problems are still currently unresolved,and a clear direction is needed for research on the automatic design base of manufacturing rules,batches reflecting changed building specifications,batch updates of boundary information for hull members,and management of the hull model change history to automate the production design process.In this study,a process was developed to aid production design engineers in designing a new ship’s hull block model from that of a similar ship previously built,based on AVEVA Marine.An automation system that uses the similar ship’s hull block model is proposed to reduce M/H and human errors by the production design engineer.First,scheme files holding important information were constructed in a database to automatically update hull block model modifications.Second,for batch updates,the database’s table,including building specifications and the referential integrity of a relational database were compared.In particular,this study focused on reflecting the frequent modification of building specifications and regeneration of boundary information of the adjacent panel due to changes in a specific panel.Third,the rollback function is proposed in which the database (DB) is used to return to the previously designed panels.     

Compatibility Measurement in Collaborative Conceptual Design

A product consists of various sub-functions elaborated by alternative design principles which results in many combinations. In collaborative design, designers expect that their preferences over the combinations be respected during the combination process of sub-functions, resulting in compatible combinations. We formulate the selection of compatible combinations as a combinatorial problem by: (i) defining a design principle as a list of variables with their domain and direction of designer's preferences, (ii) considering constraints among design principles, (iii) characterizing the compatibility level of combinations. A vacuum cleaner is considered with dust bag, plastic bin or cyclonic design principles for the dust collection sub-function.     

Characteristics and Functional Properties of Protein Isolates from Various Peanut (Arachis hypogaea L.) Cultivars

Protein isolates from 9 cultivars of peanut (Arachis hypogaea L.) were compared. Sephadex G-200 gel filtration and nondenaturing polyacrylamide gel electrophoresis (NPAGE) of the protein isolates showed very similar patterns of arachin and nonarachin fractions. The content of individual fractions was somewhat different among cultivars, possibly indicating genetic variability. Sodium dodecyl sulfate-PAGE (SDS-PAGE) showed that the protein isolates had extremely complex sub-unit compositions. The content of acidic amino acids of the protein isolates was 34–38%, basic was 15–17%. Differences in some functionalities such as solubility and emulsification activity were conspicuous among cultivars.     

THE CONTRIBUTION OF STUDIES OF SOURCE CREDIBILITY TO A THEORY OF INTERPERSONAL TRUST IN THE COMMUNICATION PROCESS.

DEFINES INTERPERSONAL TRUST IN THE COMMUNICATION PROCESS AS RELIANCE UPON THE COMMUNICATION OF ANOTHER PERSON IN ORDER TO ACHIEVE A DESIRED BUT UNCERTAIN OBJECTIVE IN A RISKY SITUATION. A THEORY OF THE DIMENSIONS OF INTERPERONAL TRUST IN COMMUNICATION IS PRESENTED. EXPERIMENTAL STUDIES OF ETHOS AND FACTOR-ANALYTICAL STUDIES OF SOURCE CREDIBILITY SUPPORT THE HYPOTHESIS THAT INTERPERSONAL TRUST IS BASED UPON A LISTENER'S PERCEPTIONS OF A SPEAKER'S EXPERTNESS, RELIABILITY, INTENTIONS, ACTIVENESS, PERSONAL ATTRACTIVENESS, AND THE MAJORITY OPINION OF THE LISTENER'S ASSOCIATES.
