Quite a number of earlier studies have found that the majority of new technology-based firms are spin-offs from existing organizations, usually established in the geographical neighborhood of the parent (Dorfman 1983; Roberts 1991; Saxenian 1994; Sternberg 1996; Keeble 1997; Lindholm Dahlstrand 1997, 2001; Lindholm Dahlstrand and Dahlander 2003). Since established corporations are responsible for

This study scrutinizes gender differences in adolescent problem behaviour and its potential determinants, simultaneously taking into account the individual and contextual level, including personality, family and country characteristics. Using the 2010 EU Kids Online Survey, we estimate multilevel models on 18,027 individuals from 24 European countries. In line with earlier research, we find that b

Vår blick på världen är inte neutral, utan medskapande. När vi betraktar ett fotografi i ett vardagligt sammanhang registrerar vår blick inte bara sinnesdata, utan skapar också mening utifrån det vi tror oss veta om ­världen. Insikten om att blicken inte är neutral får politiska implikationer då det innebär att det betraktades mening inte är given. I maktspelet om blicken blir frågan om vems blick

The development of cognitive robots in ROS still lacks the support of some key components: a knowledge integration framework and a framework for autonomous mission execution. In this research chapter, we will discuss our skill-based platform SkiROS, that was developed on top of ROS in order to organize robot knowledge and its behavior. We will show how SkiROS offers the possibility to integrate diThe development of cognitive robots in ROS still lacks the support of some key components: a knowledge integration framework and a framework for autonomous mission execution.

In order for manufacturing companies to remain competitive while also offering a high degree of customization for the customers, flexible robots that can be rapidly reprogrammed to new tasks need to be applied in the factories. In this paper we propose a method for the intuitive programming of an industrial mobile robot by combining robot skills, a graphical user interface and human gesture recogn

The registration of an observed point set to a known model to estimate its 3D pose is a common task for the autonomous manipulation of objects. Especially in industrial environments, robotic systems need to accurately estimate the pose of objects in order to successfully perform picking, placing or assembly tasks. However, the characteristics of industrial objects often cause difficulties for clas

Lipoprotein (a) [Lp(a)] is a low density lipoprotein (LDL) with one apolipoprotein (a) molecule bound to the apolipoprotein B-100 of LDL. Lp(a) is an independent risk factor for cardiovascular disease (CVD). However, the relationship of Lp(a) to diabetes and metabolic syndrome, both known for increased CVD risk, is controversial. In a population based study on type two diabetes mellitus (T2DM) dev

A new jet clustering algorithm-Arclus-is presented. The main difference between this and conventional algorithms is that while the latter in each step join two clusters into one,Arclus joins three clusters into two. The performance ofArclus in terms of the size of hadronization corrections is studied for some jet-reconstruction tasks ine+e− andep collisions, and is found to be as good as or, for s

The fourth version of the Ariadne program for generating QCD cascades in the colour dipole approximation is presented. The underlying physics issues are discussed and a manual for using the program is given together with a few sample programs.The major changes from previous versions are the introduction of photon radiation from quarks and inclusion of interfaces to the LEPTO and PYTHIA programs.

After a brief discussion of the statistics available to the four LEP experiments at the time of writing and an overview of B-event characteristics, the authors consider in particular the theory, practice and potential pitfalls of neural networks, a new approach to B tagging which attracted a great deal of interest. They then consider some of the QCD aspects of heavy flavour physics. Finally there

We present a model based upon string dynamics for the small x and large k⊥ parts of the structure functions of a hadron. These ocean partons are taken as those available in the virtual string states, which are resolved by the field pulse q, in case the process is considered as a measuring process. The resulting distributions will for sufficiently small x (x⩽O(Q−4)) behave as 1/x in case we use the

A novel modified method for obtaining approximate solutions to difficult optimization problems within the neural network paradigm is presented. We consider the graph partition and the travelling salesman problems. The key new ingredient is a reduction of solution space by one dimension by using graded neurons, thereby avoiding the destructive redundancy that has plagued these problems when using s
