User interface design metrics assist developers to evaluate interface designs in early phase before delivering the software to end users. This paper presents a metric-based tool called GUIEvaluator for evaluating the complexity of the user interface based on its structure. We defined a metrics model that includes five modified structural measures of interface complexity: Alignment, grouping, si...

The aim of this paper is to present some preliminary ideas about practical metrics and measurements useful for (i) assessing business process risk at design time and (ii) computing security and trust metrics at run time on business process orchestrations. In particular, the study is focused on a priori metrics applied to behavioral specifications of business processes (e.g., business rules and ...

This paper proposes four design metrics of class level for early and effective feedback to manage the quality of object-oriented software. These metrics measure the complexity induced by the use of various object-oriented design concepts like data hiding, aggregation, inheritance and cohesion. These four metrics are evaluated from the output of design phase before the starting of the coding to ...

Questions concerning the properties and quantification of density fluctuations in point patterns continue to provide many theoretical challenges. The purpose of this paper is to characterize certain fundamental aspects of local density fluctuations associated with general point patterns in any space dimension d. Our specific objectives are to study the variance in the number of points contained...

Vehicular Adhoc Network (VANET) is a new technology which aims to ensure intelligent inter-vehicle communications, seamless internet connectivity leading to improved road safety, essential alerts, and access to comfort and entertainment. VANET operations are hindered by mobile node’s (vehicles) uncertain mobility. Routing algorithms use metrics to evaluate which path is best for packets to trav...

The present study investigated whether subliminal (unconsciously perceived) visual information influences eye movement metrics, like saccade trajectories and endpoints. Participants made eye movements upwards and downwards while a subliminal distractor was presented in the periphery. Results showed that the subliminal distractor interfered with the execution of an eye movement, although the eff...

We present a novel way of using object oriented design metrics as to support for the incremental development of object oriented programs. Based on a quality model (factor-criteria-metrics model), so-called multi-metrics relate a number of simple structural measurements to design principles and rules. Single components of an object oriented program like classes or subsystems are analyzed to dete...
