Online analytical processing tools facilitate interactive inspection of aggregated measures of groups of data in data warehouses. In comparative data analysis, business analysts assess measures of a group of interest against measures of a group of comparison. Judgement rules annotate comparisons with background knowledge otherwise tacit to the business analyst. Analysis rules specify comparison...

Context: Organisational reengineering, continuous process improvement, alignment among complementary analysis perspectives, and information traceability are some current motivations to promote investment and scientific effort for integrating goal and business process perspectives. Providing support to integrate information systems analysis becomes a challenge in this complex setting. Objective:...

Use of database systems for storage and manipulation of business data was revolutionised by the introduction of the relational data model by Edgar Codd in 1970. Since then there have been numerous developments in the area of database modelling. Several new modelling technologies like Object Oriented, Semantic, and NoSQL have been invented. Some of them are having a significant impact in busines...

Terrain analysis based on digital elevation models is being routinely used in hydrological modelling. However, landscape connectivity enabling the routing of flow and nutrients from upslope landscape units to adjacent downslope landscape units within a sub watershed is not commonly incorporated into catchment scale models. This paper describes a process of generating connected landscape units w...

Article history: Received 20 May 2013 In final form 9 July 2013 Available online 16 July 2013 Molecular quantum-dot cellular automata (QCA) paradigm is a promising approach to molecular electronics. QCA cells can be implemented using mixed-valence compounds. However, the existence of counterions can perturb the local electric field and thus is detrimental to information encoding and processing....

In the present work, the effect of Soil-Structure Interaction (SSI) in low frequency structures resting on loose soil, through numerical modelling and shaking table tests have been studied. In theoretical studies two types of models namely fixed base and flexible base structure were subjected to three selected earthquake records. Nonlinear dynamic analysis was employed for all of the numerical ...

Driver behavior under congestion pricing is analyzed in this study to evaluate the effects of alternative congestion pricing schemes. The analysis, which is based on stated-preference survey results, focuses on time allocation, departure time choice and route choice when a congestion pricing scheme is implemented on a toll road. A unique feature of the model system of this study is that departu...

There exist a number of information systems planning(ISP) methodologies. Historically these methodologies have been evolving to reflect new technologies and business requirements. In fact, it is an uneasy task to select a methodology that fits a business need. Though there have been a number of studies proposing new ISP approaches, we are unable to find much research doing a comparative analysi...

Understanding the drivers that dictate the productivity of marine ecosystems continues to be a globally important issue. A vast literature identifies three main processes that regulate the production dynamics of such ecosystems: biophysical, exploitative and trophodynamic. Exploring the prominence among this 'triad' of drivers, through a synthetic analysis, is critical for understanding how mar...

We introduce a new application of transfer learning for training and comparing music similarity models based on relative user data: The proposed Relative Information-Theoretic Metric Learning (RITML) algorithm adapts a Mahalanobis distance using an iterative application of the ITML algorithm, thereby extending it to relative similarity data. RITML supports transfer learning by training models w...
