We have recently proposed quantized gossip algorithms which solve the consensus and averaging problems on directed graphs with the least restrictive connectivity requirements. In this paper we study the convergence ti...

This paper presents a semi-automated method that helps iteratively write use-cases in natural language and verify consistency of behavior encoded within them. In particular, this is beneficial when the use-cases are c...

Structural (manual or automated) testing today often overlooks typical programming faults because of inherent flaws in the simple criteria applied (e.g. branch or all-uses). Dedicated testing strategies that address s...

The problem of the distributed identification of a macroscopic first-order traffic model, viz. the Cell Transmission Model (CTM), is considered in the paper. The parameters to be identified characterize the dynamics of the density in different sections of the freeway (cells). We explore different distributed identification schemes. The purposes of the approach are mainly to obtain good prediction models through the minimization of the one-step ahead prediction error of the densities of the cells, and to reduce the computational time and the effort required to perform the identification. The methodology is validated relying on real-life data measured on a portion of the A12 freeway in The Netherlands. An evaluation of the performance of the identified model used as a set of virtual sensors in different scenarios is presented.
While using a single GPU is fairly easy, using multiple CPUs and GPUs potentially distributed over multiple machines is hard because data needs to be kept consistent using message exchange and the load needs to be bal...

We studied the effect of surface polarity of gate dielectric buffer layer on operational stability in organic thin film transistors (OTFTs). By employing four types of polymers with different polarity, we found out the operational stability of OTFTs can be improved with low-polarity polymer gate dielectric buffer layer. With low-polarity polymers, the devices showed good operational stability with longer relaxation time than 10 6 sec. Also, threshold voltage of the devices shifted less than 2 V under high gate bias stress of 3 MV/cm for two hours. Good stability may be resulted from low surface trap density as well as good grain interconnection of pentacene on low-polarity polymer.
