The principle of kinematic design has a wide range of applications e.g. from optical mirror mounts to parallel robots. Despite the importance of dynamic isotropy in the optimization of dynamic performance, a thorough analysis of dynamic isotropy in different kinematic arrangements has not yet been addressed in the literature. Dynamic isotropy, leading to equal eigenfrequencies, is a powerful optim

The country’s preeminent public intellectual says anti-Americanism has run its course in the Islamic republic. Hardliners will try to roll back any openings, but in the long run, the country will find itself in a better place politically, economically and socially.

Popular Abstract in Swedish Den mänskliga kroppen är ett komplext maskineri med en rad olika reglersystem och kontrollmekanismer. Flera grenar av modern biomedicinsk forskning riktar sig mot olika nivåer av detta komplexa maskineri. En av dessa grenar heter genomik, som ärläran om hur den genetiska koden som finns i varenda cell av en organism används och regleras.

Many complex diseases effect the protein composition, expression or modification in the cells or tissues they arise in. It is then no surprise that proteomics is a field full of promise, one which is expected to generate significant insights towards fu

The importance of software systems for the planning and execution of production has drastically increased over the past decades. This has lead to a growth in number of software systems used within sites. The company’s problem today is no longer only to find relevant software systems but rather to coordinate and synchronize existing systems. Students at higher technical educations e.g., bachelors a

Popular Abstract in Swedish Syftet med denna avhandling är att skapa en bättre förståelse för vilken betydelse institutioner har för innovationsprocesser inom regionala innovationssystem. Den fokuserar särskilt på hur olika typer av institutioner på skilda geografiska nivåer samspelar; hur institutionell påverkan förändras i samband med att innovationsprocesser utvecklas över tid; samt vilka möjliEconomic geographers have long been intrigued by the role of institutions in innovation processes. It has been argued that differences in institutions are among the factors explaining the uneven innovative capacity across and within countries. The regional innovation system approach highlights the interrelationships of firms, universities, governmental authorities and other organizations, as well

In this thesis an adaptive optics system has been developed, implemented and evaluated at the Lund High Power Laser facility, Atomic Physics Division, Lund Institute of Technology. The laser system delivers ultrashort pulses with peak powers exceeding 40 TW at a repetition rate of 10 Hz. The pulses are focused to achieve extreme irradiance exceeding 1019 W/cm2 . In order to increase the peak inten

Control is traditionally applied using periodic sensing and actuation. In some applications, it is beneficial to use instead event based control, to communicate or make a change only when necessary. There are no known general closed form solutions to such event based control problems. We consider stationary event-based control problems with mixed continuous/discrete time dynamics and stochastic di

Convolutional codes are defined to be equivalent if their code symbols differ only in how they are ordered and two generator matrices are defined to be weakly equivalent (WE) if they encode equivalent convolutional codes. It is shown that tailbiting convolutional codes encoded by WE minimal-basic generator matrices have the same spectra. Shearer and McEliece showed that MacWilliams identity does n
