1. 1. Nonlinearly Perturbed Renewal Equations : asymptotic Results and Applications

   Författare :Ying Ni; Dmitrii Silvestrov; Anatoliy Malyarenko; Mats Gyllenberg; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nonlinearly perturbed renewal equation; perturbed renewal equation; nonlinear perturbation; non-polynomial perturbation; perturbed risk process; perturbed storage process; Mathematical statistics; Matematisk statistik; Mathematics Applied Mathematics; matematik tillämpad matematik;

   Sammanfattning : In this thesis we investigate a model of nonlinearly perturbed continuous-time renewal equation. Some characteristics of the renewal equation are assumed to have non-polynomial perturbations, more specifically they can be expanded with respect to a non-polynomial asymptotic scale. LÄS MER

3. 2. Managing contexts for innovation and renewal : Strategies of incumbent firms in traditional manufacturing industries

   Författare :Shanyun Sam Lu; Anders Melander; Jerker Moodysson; Harald Rohracher; Jönköping University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; incumbent firms; traditional manufacturing industries TMIs ; strategy; contexts; innovation; renewal;

   Sammanfattning : Innovation is important for established firms (i.e., incumbents) in traditional manufacturing industries (TMIs) to continuously survive and thrive. While internal factors often receive attention, different factors external to these firms enable and hinder the creation and realisation of novel products and processes. LÄS MER

4. 3. A Class of Renewal Processes in Random Environments

   Författare :David Svensson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; point process; renewal process; random environment; coupling; regeneration; failure rate; Poisson embedding; asymptotics; stochastic domination; stochastic monotonicity; renewal process;

   Sammanfattning : This paper deals with a generalization of the class of renewal processes with absolutely continuous life length distribution, obtained by allowing a random environment to modulate the stochastic intensity of the renewal process. The random environment is a birth and death process with a finite state space. LÄS MER

5. 4. Understanding regional renewal and industry cluster emergence processes within the Swedish periphery

   Författare :Andrew Arbuthnott; Joakim Wincent; Jessica Eriksson; Peter Zettinig; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; industry emergence processes; regional renewal; industry clusters; periherial regions; Business studies; Företagsekonomi;

   Sammanfattning : There are many insightful writings revealing that regions within industrialised nations are able to renew their local business environments through building and supporting industry clusters. Such knowledge stems from research based on how to maintain and develop successful industry clusters located within central regions. LÄS MER

7. 5. Perturbed Renewal Equations with Non-Polynomial Perturbations

   Författare :Ying Ni; Dmitrii Silvestrov; Anatoliy Malyarenko; Yuri Belyaev; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Renewal equation; perturbed renewal equation; non-polynomial perturbation; exponential asymptotic expansion; risk process; ruin probability; Mathematical statistics; Matematisk statistik; Mathematics Applied Mathematics; matematik tillämpad matematik;

   Sammanfattning : This thesis deals with a model of nonlinearly perturbed continuous-time renewal equation with nonpolynomial perturbations. The characteristics, namely the defect and moments, of the distribution function generating the renewal equation are assumed to have expansions with respect to a non-polynomial asymptotic scale: $\{\varphi_{\nn} (\varepsilon) =\varepsilon^{\nn \cdot \w}, \nn \in \mathbf{N}_0^k\}$  as $\varepsilon \to 0$, where $\mathbf{N}_0$ is the set of non-negative integers, $\mathbf{N}_0^k \equiv \mathbf{N}_0 \times \cdots \times \mathbf{N}_0, 1\leq k .
