The world is in transition. Europe is a Europe of transition. And so is the city; an incomplete, ever-changing and complex construct. While life itself is built upon the concept of change, organic order and vitality, society is currently finding itself struggling not to fall behind time. The Industrial Revolution has led to greater productivity and larger economic turnovers. Developments picked
Flow injection analysis provides a convenient platform for the use of biosensors in the monitoring of bio-processes. A major requirement in bioprocess monitoring is real time information about various process parameters like concentration of products and substrates, flow rates, and injection volumes. Depending on the application, the monitoring requirements vary and this results in a need for diff
Experimental work in turbid media has shown that transillumination images can be significantly improved by limiting light collection to a subset of photons which are minimally distorted by scattering. The literature details numerous schemes (commonly termed ballistic imaging), most often based on time-gating and/or spatially filtering the detected light. However, due to the complex nature of the d
Semantic roles, logical relations such as Agent or Instrument that hold between events and their participants and circumstances, need to be determined automatically by several types of applications in natural language processing. This process is referred to as semantic role labeling. This dissertation describes how to construct statistical models for semantic role labeling of English text, and how
In the post-genomic era, it has become evident that genetic changes alone are not sufficient to understand most disease processes including pancreatic cancer. Genome sequencing has revealed a complex set of genetic alterations in pancreatic cancer such as point mutations, chromosomal losses, gene amplifications and telomere shortening that drive cancerous growth through specific signaling pathways
During the process of biomass gasification tars are formed which exit the gasifier in vapor phase. Tar condensation creates problems like fouling and plugging of after-treatment, conversion and end-use equipment. Gasification tars consist mainly of Polycyclic Aromatic Hydrocarbons (PAHs). Former research has shown the possibilities and difficulties of tar conversion by partial combustion. Basic st
The degradation of different polyethylenes-low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and high-density polyethylene (HDPE)-with and without antioxidants and at different oxygen concentrations in the polymer granulates, have been studied in extrusion coating processing. The degradation was followed by online rheometry, size exclusion chromatography, surface oxidation
The massive amount of genomic sequence data that is now available for analyzing evolutionary relationships among 31 placental mammals reduces the stochastic error in phylogenetic analyses to virtually zero. One would expect that this would make it possible to finally resolve controversial branches in the placental mammalian tree. We analyzed a 2,863,797 nucleotide-long alignment (3,364 genes) from
Lead time, defined as the duration between the moment a request was filed and the moment the decision was made, is an important aspect of decision making in market-driven requirements engineering. Minimizing lead time allows software companies to focus their resources on the most profitable functionality and enables them to remain competitive within the quickly changing software market. Achieving
In this paper, the critical factors behind commercialization of new product development (NPD) are investigated in order to add to our understanding of what drives and hampers the commercialization of new products and services. With the illustration of nine cases of commercialization from three multinational organizations, an initial framework of three categories of factors related to the success o
Popular Abstract in Swedish Avhandlingen består av två delar. Den första delen behandlar reglering av processer med lång dödtid. Avhandlingen ger förslag på hur regulatorer för dessa processer ska dimensioneras och jämför sedan prestanda hos dessa regulatorer med vanliga PID-regulatorer. Avhandlingens andra del handlar om metoder för automatisk övervakning av reglerkretsar i processindustrin. TvåThe thesis contains two parts, dead-time compensation and performance monitoring. The first part on dead-time compensation is about robust tuning procedures for dead-time compensating controllers (DTC). Both stable and integrating processes are considered. Simple experiments are performed to obtain process models as well as bounds on the allowable bandwidth for stability. The DTCs used have few pa
Repair and reconstruction of major nerve trunks in the upper extremity is a very challenging surgical problem. Today, there is no surgical repair technique that can assure recovery of tactile discrimination in the hand of an adult patient following nerve repair. In contrast, young individuals usually attain a complete recovery of functional sensibility. The outcome from nerve repair depends mainly
Within the Eriksonian identity tradition, exploration of different life domains is crucial to identity formation. This is a process supposed to start during adolescence and develop in a social context. Most of the adopted children in Sweden, now in adolescence, are adopted from countries outside of Europe, which means that they neither share their biological nor ethnical roots with their adoptive
Popular Abstract in Swedish Cancer är en av de vanligaste dödsorsakerna i Sverige idag och att kunna ge cancerpatienter en bättre behandling är därför av stort intresse. En del av detta arbete består av att förbättra förståelsen för hur en cellpopulation, eller då speciellt en cancertumör, växer. Ett medel för att öka kunskapen på området är att använda matematiska modeller. Förmågan att kunna fö
Background: Physical inactivity is a worldwide public health issue and the fourth leading risk factor for global mortality. As a measure of prevention or treatment several countries have developed concepts of physical activity on prescription (PAP) to tackle the common issue of sedentary behavior and thereby decrease the risk of chronic illness and premature death. The Swedish model of PAP, “Fysis
Hearing is our second most important sense. The main focus of a surveillance camera is obviously the video but the audio shouldn't be neglected. It is possible to hear what the camera can't see and what is said in a conversation can't be showed in a video. Therefore there are good reasons to always try and achieve the best audio possible. This is not an easy task since cameras are oper
