Background: While simultaneous saccharification and co-fermentation (SSCF) is considered to be a promising process for bioconversion of lignocellulosic materials to ethanol, there are still relatively little demo-plant data and operating experiences reported in the literature. In the current work, we designed a SSCF process and scaled up from lab to demo scale reaching 4% (w/v) ethanol using xylos

Effective disaster risk management is a requisite for sustainable development and it is paramount to include a wide range of stakeholders to manage risk in this context. Recent research indicates the significance of making ideas of what is valuable and important to protect explicit in any disaster risk management initiative that involves several stake- holders. The purpose of this article is thus

Although capacity development has been identified as the means to substantially reduce global disaster losses, it is a challenge for external partners to facilitate the development of sustainable capacities for disaster risk reduction in disaster-prone countries. The purpose of this study is to investigate potential gaps between how leading professionals approach such capacity development and guid

Examensarbetet är utfört vid Lunds Tekniska Högskola, avdelningen för Teknisk Geologi i samarbete med Vattenfall Research and Development AB, med syfte att undersöka åldringsfenomen och nedbrytningsprocesser av kraftverkstunnlar i berg. Livslängden för kraftverkstunnlar antas normalt vara mellan 50 och 100 år, varför många kraftverkstunnlar idag uppnått en ålder på mer än 50 år. Kraftverkstunnlar

I Sverige finns ett antal företag som med stöd av offentlighetsprincipen samlar in personuppgifter ur allmänna handlingar och publicerar dessa i söktjänster på internet. Genom användning av söktjänsterna går det att skapa sig en utförlig bild av en viss individ. Söktjänsterna har i regel beviljats utgivningsbevis och omfattas därför av grundlagsskyddet i YGL. I Sverige har en vedertagen uppfattninIn Sweden, there are several companies that, relying on the principle of public access to official documents, gather personal data and publish this information in online search services. Through use of these services, it is possible to access a detailed profile of a specific individual. The search services have generally been granted a so-called certificate of publication and are consequently prot

As robots increasingly integrate into our social environments, from factories to social spaces, there is a growing need to find ways to effectively collaborate in these dynamic environments. However, current robotics research is mostly aimed towards task and environment specific programming. Even the state-of-the-art collaborative robotics technologies lack or have a very rudimentary understanding

In the software industry, the drive to add new features often overshadows the need to improve existing code. Large Language Models (LLMs) offer a new approach to improving codebases at an unprecedented scale through AI-assisted refactoring. However, LLMs come with inherent risks such as braking changes and the introduction of security vulnerabilities. We advocate for encapsulating the interaction

Maintainable source code is essential for sustainable development. Yet, many studies show that maintainability often receives less attention than it deserves. We argue that requirements engineering can help close this gap by fostering discussions and setting appropriate targets in a responsible manner. In this preliminary work, we explore industry practices related to requirements engineering for

The relationship between requirements engineering and testing has been a key interest throughout my research career. It cannot be that requirements engineers are from Omicron Persei 7 and testers from Omicron Persei 9—we all live on the same planet. I’m happy to co-author this column with a former collaborator from a test automation EU project, now a manager at Ericsson. With this issue’s focus on

This column summarizes a panel discussion given by REFSQ 202 held in Barcelona on responsibility. Given the mediator role of our field, what other soft- ware engineering discipline could be a better fit for responsible engineering? And this will just keep getting more important as the influence of technology on society increases.

This column celebrates 40 years of IEEE Software through a retrospective on Requirements Engineering. Two seasoned experts discuss the discipline’s evolution from structured methodologies to AI-driven approaches. Finally, we speculate on future trends.

This column presents the evolution of sentiment analysis from a requirements engineering perspective. With large language models, the technology is now accessible to all. From novices to expert users, we discuss suitable ways to get started.

The C programming language, while offering high performance and low-level control, is memory-unsafe. This makes it prone to programming errors that can result in serious software vulnerabilities and system instability. In this paper, we investigate the feasibility of transitioning a large code base from C to a memory-safe alternative, specifically Rust, in the context of a large company in telecom

The Artificial Intelligence (AI) Act is a relatively new regulation set out in the European Union (EU). It lays out various requirements for AI systems that are placed on the market in the EU. This paper provides a critical and differentiated view of its requirements from a software engineering perspective. A detailed analysis of the legal document shows what requirements are set out for different

This paper addresses the time-optimal path-tracking problem for redundant manipulators. By integrating path-velocity control into existing task-space robot controllers, the task-space motion can be dynamically scaled to satisfy the torque constraint under both kinematic and dynamic uncertainties. Numerical simulations and experiments demonstrate that trajectory feasibility and path-tracking accura

Likt andra komplexa, flercelliga organismer, består den mänskliga kroppen av en mängd olika organ ämnade för olika uppgifter. För att kunna utföra dessa uppgifter är organen uppbyggda av olika sorters celler, med speciell funktion och struktur. Trots de stora skillnaderna mellan dessa celltyper delar de samma genetiska ritning, organismens genom. Genomet är indelat i olika gener, vilka beskriverMaintenance of stem cell pluripotency and the differentiation of stem cells into specialised cells has been studied extensively. More recently, the possibility for a specialised cell to be transferred into a state of induced pluripotency has been demonstrated and investigated. Critical components of the gene regulatory networks governing these processes have been identified, but a complete model h

Uppsatsen har för avsikt att komma fram till i vilken omfattning utvecklingsmetoden RUP stödjer användarmedverkan. Genom att beskriva begreppen RUP, användarcentrerad systemdesign och användarmedverkan med hjälp av litteratur har jag kunnat sammanställa ett par frågor i avsikt att utföra en intervju med tre systemvetare. Resultatet från det empiriska materialet visade att systemvetarna upplever at

En fastighetsaffär är för många privatpersoner den överlägset största affären de gör i hela livet. Varje år säljs och köps småhus för över 124 miljarder. En undersökning från Länsförsäkringar visar att en tredjedel av alla köpare oroar sig för förekomsten av ”dolda fel” i den köpta fastigheten. Mot bakgrund av den oron är det inte så konstigt att konsumentrådgivningar och liknande organisationer fA real estate transaction is for many individuals by far the largest transaction they make throughout life. Each year, sold and bought houses makes up for a value of more than 124 billion SEK. A survey, by the insurance company Länsförsäkringar, shows that one third of all buyers are concerned about the existence of "latent defects" in the purchased property. Given the turmoil, it is not
