Identifying Approaches to Usability Evaluation
Maps are ubiquitous, and created by people of all skill levels. However, many users still struggle to effectively interpret spatial information. Such users have been defined as ‘functionally map illiterate’ (Clarke 2003). This inability, or perhaps, more accurately, disability, to interpret spatial information can lead to negative experiences. This can be of great concern when these users need ...
متن کاملIntroducing Capacity Surface to Estimate Watermarking Capacity
One of the most important parameters in evaluating a watermarking algorithm is its capacity. Generally, watermarking capacity is expressed by bits per pixel (bpp) unit measure. But this measure does not show what the side effects would be on image quality, watermark robustness and capacity. In this paper we propose a three dimensional measure named Capacity surface which shows the effects of ca...
متن کاملSome Approaches to Solving a Multi - HourBroadband Network Capacity Design
In this paper, we consider solution approaches to a multi-hour combined capacity design and routing problem which arises in the design of dynamically reconngurable broadband communication networks that uses the virtual path concept. We present a comparative evaluation of four approaches, namely: a genetic algorithm; a Lagrangean relaxation based subgradient optimization method; a generalized pr...
متن کاملComparative Evaluation of Approaches to Propositionalization
Propositionalization has already been shown to be a promising approach for robustly and effectively handling relational data sets for knowledge discovery. In this paper, we compare up-to-date methods for propositionalization from two main groups: logic-oriented and databaseoriented techniques. Experiments using several learning tasks — both ILP benchmarks and tasks from recent international dat...
