DeepDive: Transparently Identifying and Managing Performance Interference in Virtualized Environments

Dejan Novakovic, Dejan Kostic, Nedeljko Vasic, Ricardo Bianchini, Stanko Novakovic

Cloud computing in general, and Infrastructure-as-a-Service (IaaS) in particular, are becoming ever more popular. Unfortunately, performance interference (and the resulting unpredictability in the delivered performance) across virtual machines (VMs) co-loc ...

VAX1 Mutation Associated with Microphthalmia, Corpus Callosum Agenesis, and Orofacial Clefting: The First Description of a VAX1 Phenotype in Humans

Vax1 and Vax2 have been implicated in eye development and the closure of the choroid fissure in mice and zebrafish. We sequenced the coding exons of VAX1 and VAX2 in 70 patients with anophthalmia/microphthalmia (A/M). In VAX1, we observed homozygosity for ...

Dead-Time Effects in Voltage Source Inverter Fed Multi-Phase AC Motor Drives and Their Compensation

Drazen Dujic

Inverter dead-time effects have been investigated in detail in the past for three-phase drives supplied from a three-phase voltage source inverter (VSI). A similar study has never been conducted in conjunction with multi-phase (more than three phases) driv ...

Actors that Unify Threads and Events

Martin Odersky, Philipp Haller

There is an impedance mismatch between message-passing concurrency and virtual machines, such as the JVM. VMs usually map their threads to heavyweight OS processes. Without a lightweight process abstraction, users are often forced to write parts of concurr ...

Characterization of micro manipulation tasks operated with various controlled conditions by microtweezers

Reymond Clavel, Mélanie Dafflon

Micro manipulation tasks with micro tweezers were operated in different configurations. This paper discusses the main issues of pick and place operations with micro tweezers as geometric consideration, grasping force and quality of the contact surfaces. Th ...
