Traditionally recommendation technologies have been focusing on recommending items to users (or users to items) and typically do not consider additional contextual information, such as time or location. In this paper we discuss a multidimensional approach to recommender systems that supports additional dimensions capturing the context in which recommendations are made. One of the most important...

In this paper, by using the way of weight coecients and technique of real analysis, a multidimensionaldiscrete Hilbert-type inequality with a best possible constant factor is given. The equivalentform, the operator expression with the norm are considered.

We discuss multidimensional generalizations of multicanonical algorithm, simulated tempering, and replica-exchange method. We generalize the original potential-energy function E0 by adding any physical quantity V of interest as a new energy term with a coupling constant lambda. We then perform a multidimensional multicanonical simulation where a random walk in E0 and V spaces is realized. We ca...

objective: the present study aimed at examining the effect of multidimensional motivation interventions based on martin's model on cognitive and behavioral components of motivation. methods: the research design was prospective with pretest, posttest, and follow-up, and 2 experimental groups. in this study, 90 students (45 participants in the experimental group and 45 in the control group) const...

A data warehouse is a database focused on decision making. It is built separately from the transactional (OLTP) databases of the enterprise, although it is partly fed from transactional data. Data warehouses are typically accessed by decision makers using OLAP tools, based on a specific, multidimensional representation of data. Considering the strategic importance of data warehouses, the qualit...

Multidimensional constructs are widely used to represent several distinct dimensions as a single theoretical concept. The utility of multidimensional constructs relative to their dimensions has generated considerable debate, and this debate creates a dilemma for researchers who want the breadth and comprehensiveness of multidimensional constructs and the precision and clarity of their dimension...
