A subjective novel approach incorporating an evidential reasoning (ER) algorithm is developed to achieve the risk estimation of ship hull vibration (SHV). A hierarchical structure for SHV modeling (hazard identification model) is constructed using a combined qualitative and quantitative approach. The quantitative criteria are converted to the qualitative criteria by applying a rule-based quantitative data transformation technique to make use of ER. A mapping process is formulated to convert and quantify the qualitative criteria. Intelligent Decision System (IDS) software is used for synthesis in the hierarchical structure and to produce the risk-estimation results graphically. The results of this paper reveal that the ER is capable of producing the risk estimation of SHV.

AbstractThis article presents a subjective, novel approach to deal with multiple criterion ship design decision making on the basis of interval data. In this novel approach, quantitative interval- and single-valued criteria are modeled and transformed into qualitative criteria by using membership functions of continuous fuzzy sets. Mapping is provided to transform criteria onto a common utility space. All the interval-valued qualitative criteria are transformed by proposing a new algorithm to represent them with a single value for each linguistic term. Normalization is carried out for all the transformed criteria. By combining all the normalized data, an evidential reasoning algorithm is applied to synthesize the generic ship design criteria. Finally, an ER-based utility ranking approach is used to select the ship with the best design criteria on the basis of the risk estimation results of ship hull vibration. The results of this research reveal that the developed approach is suitable for dealing with a ship selection problem based on the risk estimation results of ship hull vibration.

AbstractThe following paper depicts the history of Saint Simeon Stylites Uniate Parish in Rachanie since it became known in historical sources until 1811- that is the time it ceased to be an independent church unit. The introduction of the article contains the geographical location of the parish, its size and the position within the hierarchical structure of the Church. Having analysed post-visit inspection protocols left by Chelm Bishops, the appearance as well as fittings and ancillary equipment of the church in Rachanie in that particular period are reported. Moreover, the list of 4 local clergymen is recreated and their benefice is determined. As far as possible, both the number of worshipers and the number of Holy Communion receivers is determined.

Representation systems based on inheritance networks are founded on the hierarchical structure of knowledge. Such representation is composed of a set of objects and a set of is-a links between nodes. Objects are generally defined by means of a set of properties. An inheritance mechanism enables us to share properties across the hierarchy, called an inheritance graph. It is often difficult, even impossible to define classes by means of a set of necessary and sufficient conditions. For this reason, exceptions must be allowed and they induce nonmonotonic reasoning. Many researchers have used default logic to give them formal semantics and to define sound inferences. In this paper, we propose a survey of the different models of nonmonotonic inheritance systems by means of default logic. A comparison between default theories and inheritance mechanisms is made. In conclusion, the ability of default logic to take some inheritance mechanisms into account is discussed.

Defect engineering is used to augment the porosity of MIL-100. Incorporation of defects leads to structural collapse and ultimately causes amorphisation. Pair distribution function analysis reveals a stepwise collapse of the hierarchical structure.
