Robust co-synthesis of embedded control systems with occasional deadline misses

Feedback control applications are robust to occasional deadline misses. This opens up the possibility of saving scarce (computation and communication) resources on embedded platforms. Stability and performance requirements of a control loop impose restrictions on acceptable patterns of deadline misses (e.g., not too many misses in a row). Such...

Reliable vehicular broadcast using 5G device-to-device communication

With the ever-increasing call for connected vehicles and intelligent transportation applications, vehicular networking have been of significant focus recently. Demands for highly reliable communication challenge the current underlying technology and transformations in vehicular communication are discussed. The uMTC service of the next generation...

Software Defined Networking to support IP address mobility in future LTE network

Towards reliable multi-hop broadcast in VANETs: An analytical approach

Intelligent Transportation Systems in the domain of vehicular networking, have recently been subject to rapid development. In vehicular ad hoc networks, data broadcast is one of the main communication types and its reliability is crucial for high performance applications. However, due to the lack of acknowledgment techniques in IEEE 802.11p...

High-Performance Motion Control of the METIS Cold Chopper Mechanism

We present the main results of the performance test campaign of the Mid-Infrared European Extremely Large Telescope Imager and Spectrograph (METIS) Cold Chopper Demonstrator (MCCD). This tip/tilt mirror, which operates at a temperature of 77 K, is one of the critical components in the METIS for the European Extremely Large Telescope. The...

Performance assessment and Self-Organisation of Virtual Sectorisation in a realistic LTE network

Active Antenna Systems (AAS) technology is one of several advanced features that enable a mobile network operator to cost-efficiently increase its network capacity to cope with the exponential mobile data traffic growth and the ever more demanding performance requirements. AAS can be exploited to perform e.g. Virtual Sectorisation (ViS), i.e....

Computing response time distributions using iterative probabilistic model checking

System designers need to have insight in the response times of service systems to see if they meet performance requirements. We present a high-level evaluation technique to obtain the distribution of services completion times. It is based on a high-level domain-specific language that hides the underlying technicalities from the system designer....

Assessment of the energy efficiency enhancement of future mobile networks

We assess the energy efficiency of mobile networks in 2020, and compare it with a 2010 baseline. A comprehensive assessment approach is taken, considering all relevant scenario aspects such as data traffic growth, hardware evolutions, mobile network deployments and operations including network sharing and the dynamic switching on/off of radio...

Reliability in the performance-based concept of fib Model Code 2010

The design philosophy of the new fib Model Code for Concrete Structures 2010 represents the state of the art with regard to performance-based approach to the design and assessment of concrete structures. Given the random nature of quantities determining structural behaviour, the assessment of structural performance cannot be well established by...

The visible, near-infrared and short wave infrared channels of the EarthCARE multi-spectral imager

The EarthCARE satellite mission objective is the observation of clouds and aerosols from low Earth orbit. The payload will include active remote sensing instruments being the W-band Cloud Profiling Radar (CPR) and the ATLID LIDAR. These are supported by the passive instruments Broadband Radiometer (BBR) and the Multispectral Imager (MSI)...

Meeting highest performance requirements for lowest price and mass for the M1 segment support unit for E-ELT

The largest optical telescope in the world will be the E-ELT. Its primary mirror will be 42m in diameter. This mirror will consist of 984 hexagonal segments that are all individually supported. Each mirror will be controlled in six DOF while local shaping of the segments is provided by so called warping harnesses. These will correct for focus,...

LCA as performance requirement in the Dutch building decree by 2001

In February 1998 the Dutch government decided to implement sustainability re-quirements by the year 2001 in the Dutch building Decree. Part of these require-ments shall be a performance requirement for the environmental influence of the total use of materials, determined by LCA (life cycle analyses), for dwellings or residential buildings. In...
