Spatio-temporal database systems aim to answer continuous spatio-temporal queries issued over moving objects. In many scenarios such as in a wide area, the number of outstanding queries and the number of moving objects are so large that a server fails to process queries promptly. In our work, we aim to develop scalable techniques for spatiotemporal database systems. We focus on two aspects of s...

Individuals are predicted to maximize lifetime reproductive success (LRS) through selective use of resources; however, a wide range of ecological and social processes may prevent individuals from always using the highest-quality resources available. Resource selection functions (RSFs) estimate the relative amount of time an individual spends using a resource as a function of the proportional av...

Despite the importance of drivers’ actions and behaviors, underlying factors to those have not received adequate attention. Understanding contributing various before crashes could help policy makers take appropriate tackle behaviors occur. One first steps be identify by using a reliable statistical technique. It is reasonable assume that drivers vary in their decision-making processes. Thus, th...

This paper examines the process of research uptake institutionalization tak- ing place at universities in African context. It explores importance emerging concept Research Uptake Management (RUM) and provides a rationale for why it is becoming increasingly relevant within higher education sector, both inside outside Africa. In so doing, this proposes conceptual framework strengthening RUM capac...

Influences of climate on life history traits in natural populations are well documented. However, the implications of between-individual variation in phenotypic plasticity underlying observed trait-environment relationships are rarely considered due to the large, long-term datasets required for such analysis. Studies typically present correlations of annual trait means with climate or assume th...

To each discrete translationally periodic bar-joint framework C in Rd, we associate a matrix-valued function ΦC(Z) defined on the d-torus. The rigid unit mode (RUM) spectrum Ω(C) of C is defined in terms of the multi-phases of phase-periodic infinitesimal flexes and is shown to correspond to the singular points of the function Z → rankΦC(Z) and also to the set of wavevectors of harmonic excitat...
