The exploitation of slight imperfections of transmitters’ hardware for identification of wireless devices has recently emerged as an effective method for security enhancement in wireless access networks. Previously, we introduced a modelbased approach for device identification based on the imperfections of two main wireless transmitter components: the digitalto- analog converter and the power amplifier. Here, motivated […]

Software as a Service (SaaS) is an increasingly important service delivery model in cloud computing, and multitenancy makes it possible to support large scale customized tenants with only one code base. However, the complexity of multi-tenant architecture may lead to poor performance and low resource utilization. The customized demands may also lead to high operating […]

The following article results from a comprehensive, qualitative study of investment plans for installing high-speed networks in suburban and rural areas in Germany. The study’s particular purpose was to identify special implementation models that enable the realisation of such infrastructures without public grants. This article summarises factors that appear to be significant for the success of such […]

This paper presents, for the first time, the design, implementation, and characterization of a dynamically mode-matched high-frequency piezoelectrically transduced silicon disk gyroscope utilizing a unique pair of degenerate orthogonal in-plane flexural gyroscopic modes. To eliminate the need for submicron capacitive gaps and large DC polarization voltages that are needed for electrostatic tuning, a linear bidirectional […]
