Resource demands are a key parameter of stochastic performance models that needs to be
determined when performing a quantitative performance analysis of a system. However, the …

Weighted round robin load balancing is a common routing policy offered in cloud load
balancers. However, there is a lack of effective mechanisms to decide the weights assigned …

Building performance models for software services in DevOps is costly and error-prone.
Accurate service demand distribution estimation is critical to precisely modeling queueing …

DevOps is a novel trend in software engineering that aims at bridging the gap between
development and operations, putting in particular the developer in greater control of …

NoSQL databases such as Apache Cassandra have attracted large interest in recent years
thanks to their high availability, scalability, flexibility and low latency. Still there is limited …

The application of queueing network models to real-world applications often involves the
task of estimating the service demand placed by requests at queueing nodes. In this article …

In this paper, we explore bilinear and elastically deformable models for addressing jointly
3D face and facial expression recognition. An elastically deformable model is built first to …

Resource demand estimation is essential for the application of analyical models, such as
queueing networks, to real-world systems. In this paper, we investigate maximum likelihood …

Black-box modeling techniques are used when modeling computer systems with unknown
internal structure or behavior and/or when it is not feasible or too time consuming to monitor …

Large-scale clusters are often built with over-provisioned service resources, so as to satisfy
the huge demand raised by enormous users in cloud environments. By estimating the …
