Dit proefschrift richt zich op de dringende behoefte aan robuuste en veilige softwareoplossingen in kritieke infrastructuursystemen, waar plotselinge storingen ernstige gevolgen kunnen hebben. Het onderstreept het belang van tijdige software-updates, vooral in industrieën als de auto-industrie, gezondheidszorg en transport. Het benadrukt de noodzaak van naadloze rollback-mechanismen in geval van storingen.

Het onderzoek introduceert WebAssembly en WebAssembly System Interface als veelbelovende technologieën voor dergelijke toepassingen, maar identificeert een kritiek gat in hun ondersteuning voor het veelgebruikte I2C-protocol in IoT-apparaten.

Het primaire doel van dit onderzoek is om deze kloof te overbruggen door I2C-connectiviteit mogelijk te maken voor WebAssembly-applicaties, met inachtneming van strenge beveiligings-, betrouwbaarheids- en overheadbeperkingen. Daarnaast heeft het proefschrift als doel om deze aanpak te standaardiseren, waardoor de wijdverspreide toepassing in de industrie wordt bevorderd en de duurzaamheid op lange termijn van kritieke infrastructuursystemen wordt gegarandeerd.

Om dit te vergemakkelijken worden de wasi-i2c interfaces voorgesteld. Deze interfaces volgen het capability-based security design principe dat centraal staat binnen WebAssembly System Interface. Om de deugdelijkheid van wasi-i2c vast te stellen worden implementaties geleverd. Deze implementaties variëren van verschillende runtimes, platformen en architecturen. Daarna wordt een evaluatie van de gemiddelde uitvoeringstijd en het geheugengebruik uitgevoerd.

Climate change has a significant impact on agricultural production because of its reliance on
environmental factors. Like in most parts of the world, the climate in Belgium is changing with
projections of increase in winter precipitation and decrease in summer precipitation. With
accompanying higher temperatures, evaporation will increase, and water availability will decrease,
especially in summer. It then becomes necessary to efficiently manage soil water for sustainable
crop production. While conservation agriculture is a promising climate smart agricultural
technology, it is often considered with less focus on mulching, one of the pillars of CA. In cases
where mulching has been studied, it was mostly under conventional tillage system, and about yield
and greenhouse gases emission. Since there is no one-size-fits all on soil water management. It is
imperative to conduct strategies suitable to local conditions. Potato is a staple crop in Belgium,
and it is drought sensitive. This makes it susceptible to effects of climate change. Therefore, this
research studied the impacts of mulching, under reduced tillage, on soil water balance and potato
growth as an adaptation strategy to climate change in the Flemish agricultural context.
A field experiment was conducted on a bio-parcel of the Flanders research institute for agriculture,
fisheries and food in Melle, East Flanders, Blegium. This study evaluated the effects of two
different mulch thickness (6 cm and 12 cm) against bare soil (no mulch) on evapotranspiration
(ET), potato growth, yield and water use efficiency (WUE). An adapted soil water balance
equation was used to determine ET; plant height and leaf area index (LAI) were used as parameter
of crop growth; and WUE was determined as a quotient of yield and ET. Data collected were
subjected to analysis of variance and significantly different means were separated using Tukey’s
Honestly Significant Difference (HSD) at 5% level of significance.
This study revealed that soil structural quality and soil water content improved under mulch; 12
cm mulch performed best in preventing drought stress during low rainfall; ET increased with
increasing mulch thickness though not significantly; 12 cm mulch significantly increased LAI
compared to other treatments; and yield and WUE were not significantly different among the
treatments though 6 cm and 12 cm mulch increased yield by 7.4% and 10.9% respectively.

In haar bachelorproef Fantastic beasts and their value in youth work – The magic of animals on the resilience of vulnerable adolescents breekt Hanne Van Hoylandt een lans voor de implementatie van dieren als co-coaches of -therapeuten in het zorgtraject van kwetsbare jongeren, zowel in het onderwijs als in een begeleidingscontext.

Ruimtelijke strategieën om Vlaanderen weerbaar te maken tegen droogte. Hoe verschillende onderdelen van het valleisysteem meer neerslag kunnen vasthouden en infiltreren.

In a highly unequal society, many young Brazilians suffer oppression based on their class, race, gender, sexual orientation and religion. In the transition to adulthood, a period that is already marked by important changes, this brings along specific needs that need to be met. This research answers how ICBIE, a cultural centre in Salvador da Bahia, tries to meet those needs by providing a
space for young people to participate in activities and volunteer. Young adults from the region and volunteers of ICBIE have participated in a survey and in-depth interviews to find the answer to the central question of this thesis:
“How does volunteering at ICBIE contribute to the personal and professional development of young adults living on the Itapagipe Peninsula of Salvador, Bahia?”. Their answers, insights and stories were complemented by observations and were compared with, and analyzed through the lens of
national data and concepts from Robert Havighurst, Social Justice Theory and Anti-Oppressive Practises. The results show that young adults face a multitude of obstacles, mostly related to oppressive practises. Classism is the form of
oppression that stood out, connecting almost all of the respondents. And while ICBIE can’t directly change the root of these oppressive practises, it mitigates the harmful effects caused by them, by creating a place where volunteers can
learn, take up responsibility, open their view on the world, create meaningful bonds, feel safe and loved, and cultivate hope and resilience for the future.

Effect van droogte op de stamgroei: onderzocht tot op het bot Bossen – de oplossing voor klimaats-verandering of de dupe ervan?Het afgelopen jaar sloegen meer mensen op de vlucht voor natuurrampen dan voor oorlog en geweld. Klimaatexperten voorspellen extremere weersomstandigheden als gevolg van de klimaatsverandering. Voorbeelden hiervan zijn tyfoons, stormen en steeds langere droogteperiodes die vooral het zuidelijk halfrond treffen. Bosecosystemen hebben een onmiskenbare bufferende en regulerende functie in dit verhaal.

 
This thesis describes how the social-ecological system around the Mara wetlands has changed during the previous five decades. These wetlands are mainly fed by the Mara River, which has its sources in the Kenyan Mau Escarpment. After flowing through two worldfamous wildlife parks (Serengeti and Maasai Mara), it continues in the downstream Tanzanian Mara wetlands and finally flows out in Lake Victoria.
The major focus of this thesis is on how the riparian Wakenye people in Northwest Tanzania have adapted their livelihoods to the changing context.
