Software architecture based design demands new tools for managing the different versions generated during the design process. Based in a generic process versioning administration model, a model for capturing and managing the products of the software architecture design process is presented. Thus, the proposed model enables the designer to trace such design process and its resulting products, a ...

A standard approach to analyzing n binary matched pairs being usually represented in n 2× 2 tables is to apply a subject-specific model; for the simplest situation it is the so-called Rasch Model. An alternative population-averaged approach is to apply a marginal model to the single 2 × 2 table formed by n subjects. For the situation of having an additional stratification variable with K levels...

We consider the situation in two sample testing when one variance is assumed to be known while the other variance is considered unknown. This situation arises, for example, when one is interested in comparing a standard treatment with a new treatment. Although this situation occurs relatively infrequently, our example discusses the important tool of moment matching and makes the classic two sam...

in applications there occur different forms of uncertainty. the twomost important types are randomness (stochastic variability) and imprecision(fuzziness). in modelling, the dominating concept to describe uncertainty isusing stochastic models which are based on probability. however, fuzzinessis not stochastic in nature and therefore it is not considered in probabilisticmodels.since many years t...

This paper begins with the assumption that possible worlds and times are represented as situation pronouns in natural language (see Cresswell, 1990; Percus, 2000; Kusumoto, 2005; Keshet, 2008). For simplicity, situations are construed to be world-time pairs, and a predicate taking such a pair as an argument is evaluated in the world and the time specified. Researchers such as Percus (2000) have...

education. Today, a qualitative movement toward efficient trainings ineducational systems is necessary, since one of the important factors in the development and progress of any society is necessarily resources, manpower and their education.Considering education as a basic system in growing human resources, the present article tries to address this matter, due to the fact that we are in a situ...

ion is a natural operation in semantics. By abstracting Paul from the information σ that Raymond cooked the omelette for Paul, we obtain the property of being someone for whom Raymond has cooked the omelette. By abstracting both Paul and the omelette from σ, we obtain the relation which holds between x and y just in case Raymond cooked x for y. This relation and the previous property differ fro...

Motivated by the empirical findings concerning the importance of one’s current situation on her choice behavior, the main objective of this paper is to propose a rational choice theory that allows for the presence of a status quo bias, and that incorporates the standard choice theory as a special case. We follow a revealed preference approach, and obtain two nested models of rational choice tha...

Publised in Periodica Polytechnika 1999 Abstract The present situation in Hungary is introduced in the field of GIS data exchange in this paper. Most of the data exchanges concentrate on map data (graphical data) without attributes. The new Hungarian standard DAT1 (MSz 7772-1) has changed the situation. It involves map, topology and attribute data as well. This is the official data exchange for...
