Validation of control-oriented heavy duty diesel engine models for non-standard ambient conditions

Complying to both the increasingly stringent pollutant emissions as well as (future) GHG emission legislation - with increased focus on in-use real-world emissions - puts a great challenge to the engine/aftertreatment control development process. Control system complexity, calibration and validation effort has increased dramatically over the...

LTE Delay Assessment for Real-Time Management of Future Smart Grids

This study investigates the feasibility of using Long Term Evolution (LTE) cellular networks for the real-time smart grid state estimation. The smart grid state estimation requires measurement reports from different nodes installed in the smart grid. Therefore, the uplink LTE radio delay performance is selected as key performance indicator for...

Building Better Performance Measures for Better Conversations to Provoke Change

Injury rates are a thing of the past: building better performance measures for better conversations to provoke change. The Oil & Gas industry has measured safety performance using Injury frequency rates for the last 40 years. Industry thinking is based on the premise that: if we do not have injuries then we are safe, and if we have injuries we...

LTE delay assessment for real-time management of future smart grids

This study investigates the feasibility of using Long Term Evolution (LTE), for the real-time state estimation of the smart grids. This enables monitoring and control of future smart grids. The smart grid state estimation requires measurement reports from different nodes in the smart grid and therefore the uplink LTE radio delay performance is...

Development of a smart key performance indicator for in-situ load tests

In-situ load testing of reinforced concrete (RC) structures is often performed to confirm the presence of the required resistance for the intended use (Conformity Load Testing) or to support the assessments of the residual capacity by models (Supplementary Load Testing for Condition Assessment). When performing an in-situ load test, one of the...

Smart city performance measurement framework. CITYkeys

This paper presents a holistic performance measurement framework for harmonized and transparent monitoring and comparability of the European cities activities during the implementation of Smart City solutions. The work methodology was based on extensive collaboration and communication with European cities in order to develop a set of Key...

Sweet spot identification in underexplored shales using multidisciplinary reservoir characterization and key performance indicators: Example of the Posidonia Shale Formation in the Netherlands

Sweet spot identification in underexplored shale gas basins needs to be based on a limited amount of data on shale properties in combination with upfront geological characterization and modelling, because actual production data is usually absent. Multidisciplinary reservoir characterization and integration of modelling approaches can aid initial...

High reliability organizations

High Reliability Organizations (HRO’s) are organizations that constantly face serious and complex (safety) risks yet succeed in realising an excellent safety performance. In such situations acceptable levels of safety cannot be achieved by traditional safety management only. HRO’s manage safety risks in a specific way, supported by an associated...

Mitigation of terrain induced slugging using mixer devices

The present work focuses on experimental evidence of slug mitigation via various devices. The slug mitigation potential of a number of mixers was tested using a laboratory scale air/water setup to compare their effect on the incoming slugs just upstream of the separator inlet. Dedicated methods and key performance indicators were developed to...

Demonstrator for objective driven SON operation

The demonstrator shows a self-management system for heterogeneous mobile wireless networks that uses context-specific and weighted Key Performance Indicator (KPI) target values defined by the operator to automatically and autonomously configure and control the operation of Self-Organising Network (SON) functions such that they contribute to...

Risk-based asset management of a navigation network

In the Netherlands the State Public Works is responsible for the main waterway network, where locks are mostly the decisive bottlenecks in the navigation corridors. In the last decade the State Public Works has changed from a technical oriented maintenance organization mainly focussed at the component and asset level to a user oriented service...

ThermoGIS: An integrated web-based information system for geothermal exploration and governmental decision support for mature oil and gas basins

In the recent years the use of geothermal energy through implementation of low enthalpy geothermal production systems for both electricity and heating have been growing rapidly in north-western Europe. Geothermal exploration and production takes largely place in sedimentary basins at depths from 2 to 5 km. Geothermal activities can take...

Costs and benefits of interventions related to key performance indicators

An ergonomic intervention is regarded as an investment, which has to be worthwhile and lead to added value for an organisation. In business, key performance indicators (KPIs) are used to measure the extend to which certain economic goals, in terms of added value, are being achieved. These indicators often differ from sector to sector and from...
