Referral techniques are normally employed in internet business applications. Existing frameworks prescribe things to a particular client according to client inclinations and former high evaluations. Quite a number of methods, such as cooperative filtering and content-based methodologies, dominate the architectural design of referral frameworks. Many referral schemes are domain-specific and cannot be deployed in a general-purpose setting. This study proposes a two-dimensional (User × Item)-space multimode referral scheme, having an enormous client base but few articles on offer. Additionally, the design of the referral scheme is anchored on the  and  articles, as expressed by a particular client, and is a combination of affiliation rules mining and the content-based method. The experiments used the dataset of MovieLens, consisting of 100,000 motion pictures appraisals on a size of 1-5, from 943 clients on 1,682 motion pictures. It utilised a five-overlap cross appraisal on a (User × Item)-rating matrix with 12 articles evaluated by a minimum of 320 clients. A total of 16 rules were generated for both  and  articles, at 35% minimum support and 80% confidence for the  articles and 50% similitude for the . Experimental results showed that the anticipated appraisals in denary give a better rating than other measures of exactness. In conclusion, the proposed algorithm works well and fits on two dimensional -space with articles that are significantly fewer than users, thus making it applicable and effective in a variety of uses and scenarios as a general-purpose utility.

In two-dimensional space, an elasto-plastic finite element computational model was established to simulate inner support for excavation on the basis of the general-purpose finite element software ABAQUS. The soil was assumed to be a uniform and normally consolidated clay layer and strut was discreted by spring element. Compared with published case study, it can be concluded that FEM software AQAQUS can present one reliable simulation progress of inner support for excavation.

Grouping Pattern

Human behaviors and activities are general in horizontal direction. Architectural designer’s operation on drawings and computer screen is a two-dimensional space form and is a visual feature of plane. So in making architectural design, we usually start from the plane. The article thinks the constitution pattern of architectural plane can be roughly divided into two patterns: geometric grouping pattern and space field model around the architectural center. And the article gives a detailed analysis on it.

This paper presents an approach to automatic user interface code generation that is based on an internal HCI standard that defines layout and behaviour of coarse-grained objects for enterprise business applications. A domain-specific language (in the form of a UML profile) based on the concepts introduced by the HCI standard facilitates efficient modeling and generation of fully-functional UIs. Being a regular UML extension, this language can be used in any general-purpose UML modeling tool and can easily be integrated with other UML-based models of the application.

Analysis Of Time Series

Forecasting the evolution of industrial processes can be useful to discover faults. Several techniques based on analysis of time series are used to forecast the evolution of certain critical variables; however, the amount of variables makes difficult the analysis. In this way, the use of dimensionality reduction techniques such as the SOM (Self-Organizing Map) allows us to work with less data to determine the evolution of the process. SOM is a data mining technique widely used for supervision and monitoring. Since the SOM is projects data from a high dimensional space into a 2-D, the SOM reduces the number of variables. Thus, time series with the variables of the low dimensional projection can be created to make easier the prediction of future values in order to detect faults.

Kiekvienas žingsnis reikalauja atidos ir turėtų būti automatizuotas. Straipsnyje yra pateikiamas biojutiklio metamodelis, leidžiantis formuluoti biojutiklių modelius dalykinės srities sąvokomis.

When developing new biosensors, a lot of experiments are needed to be performed. Mathematical modeling of biosensors is used to decrease the number of physical experiments. Models of biosensors are usually created for each structurally unique biosensor by defining its mathematical model and the corresponding numerical approximation. Equations of the numerical model are then solved using computer programs, usually created for a particular model of the biosensor. Each of these steps requires a great attention and should be automated. The article presents a metamodel for a biosensor, enabling one to define models of biosensors in domain-specific terms. The proposed metamodel describes biosensor models, defined in the two-dimensional space and including definitions of the structure of a biosensor, its geometrical properties, reactions and diffusion processes taking place in it. Upon defining the metamodel, we compiled the computer software able to create computer models for biosensors from the models formulated according to the proposed metamodel. The metamodel was practically used to define a model for a real biosensor, and the biosensor modeling software was used to simulate its operation.

Policy Choices

This chapter uses the cleavage positions of Candidates to the European Parliament (CEPs) to as representative of their parties’ political positions. Three surveys of CEPs track the evolution of party supply in European party systems. In 1979 parties were primarily aligned along a Left–Right economic cleavage. Gradually new left and Green parties began to compete in elections and crystallized and represented liberal cultural policies. In recent decades new far-right parties arose to represent culturally conservative positions. The cross-cutting cultural cleavage has also prompted many of the established parties to alter their policy positions. In most multiparty systems, political parties now compete in a fully populated two-dimensional space. This increases the supply of policy choices for the voters. The analyses are based on the Candidates to the European Parliament Studies in 1979, 1994, and 2009.
