The thesis asks whether the constrains imposed by complex functional programs and associated design guidance limit the ability to deploy design languages with entail their own precise compositional requirements. The Islip Federal Courthouse designed by Richard Meier under the General Services Administrations Design Excellence Program is chosen as a case study for two reasons: First, the functional constraints are explicitly documented, and their effects can be studied through a comparative analysis of recent Courthouses also built under the same GSA program; Second, Meiers language has received much scholarly attention, is well understood, and can be described with rigor. Both the functional requirements or constraints and the compositional principles associated with the design language are described as formal structures. The thesis shows that, in this instance, all functional constraints can be satisfied without compromising the elaboration of the language. Thus, the thesis contributes to our understanding of design logic and supports the idea that design intentions as well as design considerations can be reconstructed through a systematic study of the designed object

The partitioning of complex processor models on the gate and register-transfer level for parallel functional simulation based on the clock-cycle algorithm is considered. We introduce a hierarchical partitioning scheme combining various partitioning algorithms in the frame of a competing strategy. Melting together the di®erent partitioning results within one level using superpositions we crossover to a mixture of experts one. This approach is improved applying genetic algorithms. We present two new partitioning algorithms (experts), the Backward-Cone-Concentration algorithm (n-BCC) and the Minimum-Overlap Cone-Cluster algorithm (MOCC), both of them taking cones as fundamental units for building partitions.

The partitioning of complex processor models on the gate and register-transfer level for parallel functional simulation based on the clock-cycle algorithm is considered. We introduce a hierarchical partitioning scheme combining various partitioning algorithms in the frame of a competing strategy. Melting together different partitioning results within one level using superpositions we crossover to a mixture of experts one. This approach is improved applying genetic algorithms. In addition we present two new partitioning algorithms both of them taking cones as fundamental units for building partitions.

The vision of a circular economy (CE) promises both profitability and eco-sustainability to industries, and can, from a material and energy resource flow perspective, be operationalized by combining three business and design strategies: closing loops; narrowing and slowing down resource flows by material recycling, improving resource efficiency; and by extending product life by reuse, upgrades and remanufacturing. These three strategies are straightforward ways for industries to radically reduce their use of virgin resources. From a product design perspective, it is doable. However, from a business perspective, it is no less than a revolution that is asked for, as most Original Equipment Manufacturers (OEMs) have, over time, designed their organizations for capturing value from selling goods in linear, flow-based business models. This thesis aims to contribute to the discourse about CE by exploring practical routes for operationalizing circular product design in a “stock-based” CBM. The approach is three-fold. Firstly, the role of design as a solution provider for existing business models is explored and illustrated by case studies and interviews from the automotive industry. Secondly, challenges and possibilities for manufacturing firms to embrace all three strategies for circularity are explored. Thirdly, implications for designing products suitable to stock-based CBMs are discussed. In spite of the vast interest in business model innovation, a circular economy, and how to design for a circular economy, there are still many practical, real-life barriers preventing adoption. This is especially true for designing products that combine all three of the circular strategies, and with regard to the risk of premature obsolescence of products owned by an OEM in a stock-based business model. Nevertheless, if products are designed to adapt to future needs and wants, business risks could be reduced. The main findings are that CE practices already have been implemented in some respects in the automotive industry, but those practices result in very low resource productivity. Substantial economic and material values are being lost due to the dominant business and design logic of keeping up resource flows into products sold. The primary challenge for incumbent OEMs is to manage, in parallel, both a process for circular business model innovation and a design process for future adaptable products. / <p>This licentiate studies have been financed by the Swedish EnergyAgency.

Ett allt vanligare fenomen är att civila samhällsaktörer använder drönare i arbetet. En av dem är Polismyndigheten vars förmåga benämns UAS, en akronym för Unmanned Aircraft System. UAS används bland annat för ledning av operativa insatser. Syftet med studien var att undersöka hur användningen av UAS påverkar polisens ledning av insatser. Den polisiära UAS-användningen har för avsikt att höja polisens ledningsförmåga. Enligt tidigare forskning kan detta normativa påstående tolkas som ett designförslag. Med denna utgångspunkt undersökte studien empiriskt hur UAS-användningen påverkar polisens möjligheter att nå önskade effekter av insatser. Undersökningen genomfördes med stöd av Brehmers (2013) designlogik bestående av fem analysnivåer. Designlogiken applicerades på primärt på ledningssystemet i relation till insatssystemet.  Empirin utgjordes av sju individuella och semistrukturerade intervjuer. Intervjuerna analyserades med deduktiv tematisk analys. Resultaten visar att det finns effekthöjande faktorer, effekthämmande faktorer och effektsänkande (risk)faktorer gällande polisens UASanvändning vid insatsledning. Studiens slutsats är att det är hur relationen mellan dessa faktorer ser ut vid varje unik insats som påverkar vilken betydelse UAS-användningen får för ledningsförmågan, och därmed också vilka effekter som kan uppnås med insatsen som helhet. Det finns därmed en riktighet, men inte en garanti, i påståendet att UAS-användning genererar ökad ledningsförmåga vid ledning av operativa insatser. Att UAS-användningen höjer ledningsförmågan förutsätter att omständigheterna är gynnsamma/hanterbara och att de effektsänkande (risk)faktorerna kan undvikas/hanteras. / An increasingly common phenomenon is that civil society actors utilizes drones in work-related situations. Amongst them is the Swedish Police Authority, whose capability entitles UAS, an acronym for Unmanned Aircraft System. One way in which the Swedish police uses UAS is for command and control (C2) of operations. The purpose of the study was to investigate how the UAS-usage affects the management of C2 operations. Through UAS-usage, the Swedish police intends at increasing the police's C2 ability. According to previous research, this normative statement could be interpreted as a design proposal. Following this, the study investigated empirically how the UAS-usage affects the police's ability to achieve desired effects of C2 operations. To conduct the research, the study used Brehmer's (2013) design logic consisting of five levels of analysis. The design logic was applied primarily to the C2-system in relation to the mission respondent system.  The empirics consisted of seven semi-structured interviews, which all took place individually. The interviews were analyzed with deductive thematic analysis. Results are showing that UAS-usage in C2 operations has effect-enhancing factors, effect-inhibiting factors and effect-reducing (risk) factors. The study states that the relationship between these factors in each unique C2 operation affects how UAS-usage influences the C2 ability, and hence which effects the operation as a whole produces. There is thus an accuracy, but not a guarantee, in the claim that UAS-usage generates increased C2 ability. The achievement of increased C2 ability through UAS-usage is dependent on favorable/manageable circumstances and the fact that the effect-reducing (risk) factors can be avoided/managed.
