Designing e-learning services : a case study
No full textRecently, increasing numbers of e-learning tools have been developed. However, the benefits of these tools cannot be fully used as they typically operate separately and do not communicate with each other. It is necessary to develop a solution to redeploy existing tools, and create new tools, in a more effective way. Our approach is to link and manage these e-learning tools together, by grouping the tools together and presenting them as a set of e-learning services, implemented using service technologies. In this paper, we propose a set of e-learning services, together with the approach we have adopted to develop them, which are developed based on a case study

Work-family segmentation preferences and work-family conflict: mediating effect of work-related ICT use at home and the multilevel moderating effect of group segmentation norms
No full textDrawing on boundary theory, we propose a multilevel model that examines the effects of group segmentation norms on individual-level processes, relating segmentation preferences to work-family conflict via the use of a technological boundary. Data from 350 married employees in 81 working groups were used to test the model. The results of multilevel analysis revealed that work-related information and communication technology (ICT) use at home mediated the relationship between employee work-family segmentation preferences and work-family conflict, and the segmentation norms of the team moderated the relationship between work-family segmentation preferences and work-related ICT use at home. Managerial and practical implications are discussed
Mesoscale modeling of mechanical deterioration in sulfate-attacked concrete
No full textThis study presents a mesoscale mechanical deterioration model to investigate the chemo-mechanical degradation of concrete under sulfate attack. The model introduces sulfate-induced volumetric expansion at the microscopic level and incorporates its macroscopic equivalent expansion strain into a mechanical damage framework. A two-dimensional polygonal random aggregate structure is employed to reflect the heterogeneous microstructure of concrete and simulate damage evolution under sulfate attack. Validation against published experimental data demonstrates the model's accuracy in capturing expansion behavior, cracking patterns, and compressive strength degradation under sulfate exposure. Simulations reveal non-uniform damage initiation at aggregate corners and propagation along aggregate–mortar interfaces, ultimately leading to macrocracking and strength loss. A continuous decline in compressive strength with increasing exposure duration confirms the model's predictive capability. The study underscores the critical role of concrete heterogeneity in influencing ion transport, damage localization, and failure mechanisms. By distinguishing between mortar and aggregate phases, the model reflects tortuosity and dilution effects on ion diffusion and reaction product accumulation. This mesoscale framework offers mechanistic insight into the coupled transport–mechanical processes driving sulfate-induced degradation. Despite simplifications such as the exclusion of the interfacial transition zone and post-cracking transport evolution, the model provides a foundation for future refinements and supports the durability assessment of concrete structures in aggressive environments.</p
Achievable rate analysis of the generalized spatial modulation uplink in multi-cell multi-user systems in the face of pilot contamination
No full textThe sum-rate of the multi-cell multi-user generalized spatial modulation (GSM) uplink is analyzed in the presence of realistic pilot contamination. A practical channel model associated with arbitrary transmit and receive correlation matrices is assumed for each user and base station (BS). Imperfect channel estimation is assumed with pilot contamination. The performance of a single-cell based minimum mean squared error (SMMSE) combiner is analyzed and compared to the ubiquitous zero forcing (ZF) combiner as well as matched filtering (MF). The transmit antenna (TA) index detection and the classicamplitude/phase modulation (APM) signal detection process are carried out separately for the sake of low complexity. Moreover, an algorithm based on order statistics is proposed for calculating the antenna detection probability conditioned on the actual TA. Finally, an approximation of the sum-rate is derived by exploiting the characteristics of massive MIMOs. Simulation results show that SMMSE has the best performance, followed by ZF and MF. Furthermore, the relationships between the system’s achievable rate and three systems parameters, namely the number of BS antennas, the signal-to-noise-ratio (SNR) and the interference factor of pilot contamination, are presented. The performance of different number of activated antennas are also compared.<br/
