In the EU AUTOPILOT project, IoT is brought into the automotive world to transform connected vehicles — moving ‘things’ in the IoT ecosystem — into highly and fully automated vehicles. One of the considered use cases is the platooning use case, which is being tested at the Brainport pilot site in the Netherlands. The aim of this use case is to...

Motivated by automotive emission legislations, a Virtual NOx sensor is developed. This virtual sensor consists of a realtime, phenomenological model that computes engine-out NOx by using the measured in-cylinder pressure signal from a single cylinder as its main input. The implementation is made on a Field Programmable Gate Array–Central...

This study deals with ductile fracture prediction of a marine steel using new damage functions. The stress triaxiality and Lode angle are known to be governing parameters on the ductile fracture. Recent research has reported that loading path is also one of the important parameters. A three-dimensional fracture strain surface for EH36 steel was...

The aim of this paper was to investigate the effect of natural carbonation on the pore structure, and elastic modulus (E-m) of alkali-activated fly ash (FA) and ground granulated blast furnace slag (GBFS) pastes after one year of exposure in the natural laboratory conditions. The chemical changes due to carbonation were examined by X-ray...

The current theory of ASR gel formation in concrete between silicic acid anions with cations and is unable to explain the differences in concentration required for gel formation between e.g. potassium and sodium or the effect of calcium on the gel formation. In this paper, a new gelation mechanism is explained by means of a condensation between...

Frisse lucht zorgt voor een goede en diepere slaap. Dus bieden veel kinderdagverblijven de mogelijkheid om kleintjes buiten te laten slapen. Kan dat onder alle weersomstandigheden? En waar let je op als het bijvoorbeeld pijpenstelen regent of vriest dat het kraakt?

Pressure pulsations are an intrinsic feature of reciprocating compressor systems, that may lead to various issues. The API 618 standard is the most relevant guideline for pulsation and vibration control during the design stage. However, the main focus of API 618 is on pulsation effects in the field piping, and less on the pulsations close to the...

Cement paste is the glue that holds concrete together and any improvements in material performance will come from its microstructure. For better understanding and predicting its elastic properties and fracture performance, more and more studies are carried out based on micromechanics simulations. However, the predicted results can be hardly...

One of the pending issues regarding Homogeneous Charge Compression Ignition (HCCI) engines is high load operation limit constrained by excessive pressure rise rates (PRRs). The present study investigates various measures to reduce combustion harness in a residual-affected HCCI engine. At the same time, the impact of those measures on efficiency...

De vraag naar grondstoffen voor de bouwopgaaf, de grote hoeveelheid (sloop)afval uit de bouw en de impact van de bouwsector op broeikasgasemissies vragen om een efficiënte en duurzame manier omgang met bouwmaterialen. Het Rijksbrede programma circulaire economie was voor TNO aanleiding om in deze publicatie te laten zien hoe wij aankijken tegen...

Design methods for marine structures have evolved into load and resistance factor design, however existing partial safety factors related to berthing velocity and loads have not been verified and validated by measurement campaigns. In this study, field observations of modern seagoing vessels berthing in Bremerhaven, Rotterdam and Wilhelmshaven...

De Afsluitdijk is op dit moment ruim tachtig jaar oud en heeft ons al die jaren goed tegen de krachten en invloeden van het zeewater beschermd (foto 1 en 2). Rijkswaterstaat gaat de Afsluitdijk nu een grote opknapbeurt geven, zodat hij tot ten minste 2050 mee kan. De dijk wordt zodanig versterkt dat hij bestand is tegen het stijgende zeewater....

In the present paper, laboratory produced, animal origin biofuels (swine lard and turkey lard had been used as raw material for biofuel production) were evaluated in terms of physicochemical parameters and compared with commercial mineral diesel fuel and its mixture with rapeseed oil methyl esters. Basing on the results of physicochemical...

For a large new refinery project in the Middle East, the design and construction of a very large hydrogen compression unit was required. The compression unit design resulted in the requirement for six large reciprocating compressors operating in parallel, with a total installed electrical power close to 100 MW. The compressors have common...

Interaction of ultrasonic waves with partially-closed surface-breaking cracks in concrete structures has been studied. Measurements have been conducted on a reinforced concrete beam containing various mechanical-load-induced cracks and compared with the baseline measurements at those locations. Influence of crack width, incident angle of waves...

In this paper, identification of energy dissipation in the joints of a lab-scale structure is accomplished. The identification is carried out by means of an energy flow analysis and experimental data. The devised procedure enables to formulate an energy balance in the vicinity of the joints to obtain local energy dissipation. In this paper, a...

Recirculation hoods equipped with carbon and plasma filters are becoming more and more popular. The aim of this study is to determine the effectiveness of recirculation hoods with regard to PM2 5 and NOx removal in a 26 m3 lab kitchen with a gas furnace. With the carbon filter PM2 5 is reduced for about 30%. A fresh carbon filter removed about...
