Over the years, Radio Resource Management has been benchmarked mostly by its technical merits. For a service provider, however, also economics must be considered. When the financial needs of the provider and the satisfaction of the users are considered, common objectives in radio resource management like maximising throughput or meeting various quality constraints, are no longer sufficient. We ...

Despite the ubiquitous proliferation and importance of Enterprise Systems (ES), little research exists on their post-implementation impact on firm performance, especially in Europe. This paper provides representative, large-sample evidence on the differential effects of different ES types on performance of European enterprises. It also highlights the mediating role of innovation in the process ...

Simulating enterprise environments poses several challenges by virtue of the complex nature of enterprise applications and the systems that need to be modeled. In this paper, we propose an alternate approach to simulating such environments that uses resource utilization traces from real deployments in conjunction with high-level models that correlate resource utilization to system metrics like ...

An important problem of broadband Internet infrastructures is efficient resource utilisation at access points, while keeping the Quality of Service (QoS) demands of applications stable and optimal. Considering the resource bottleneck of broadband access networks, there is a need for integrated performance management of such networks providing “feedback” from monitoring and analysis of traffic, ...

Commercial sugarcane records for 19 seasons from 146 fields were obtained from five estates in the KwaZulu-Natal Midlands. Extensive editing and cleaning of the agronomic records was required. Regression models were developed, and depending on the predictor variables selected, the best model accounted for 55% of the observed yield variation, based on 535 crop cycles. The final models were valid...

A successful enterprise resource planning (ERP) system ultimately requires loyal use—proactive, extended use and willingness to recommend such uses to others— by employees. Building on interactional psychology literature and situational strength theory, we emphasize the importance of psychological commitment, in addition to behavioral manifestation, in a multilevel model of loyal use. Our empir...
