Design of mixed MPLS/OSPF routing in IP networks

In this paper we address the problem of Internet networks optimization using a mixed Open Shortest Path First (OSPF) and Multi Protocol Label Switching (MPLS) routing. Since MPLS can be combined with any routing protocol there appeared an idea of coupling IP streams routed via OSPF protocol and MPLS Label Switched Paths (LSPs) in the same network. One expected advantage behind such a combined rout

Board task performance in small owner-managed companies - Exploring a construct through three case studies.

It is far from evident that small owner-managed companies can use the capacity of a board of directors. A well known construct of board task performance is expressed in the activities of control, strategy making, and service (C-SM-S construct). The aim is to explore the construct, which has been derived from studies on large and medium-sized companies, in a new setting. The analysis of three cas

A CNN hardware-only approach to speed measurement

Vision sensors are of increasing interest for non-destructive, remote measurements in industrial as well as consumer products. Their operation is based on intelligent techniques for image understanding, followed by robust quantification of the detected phenomenon. A well-known application area is movement detection and isolation. This paper discusses how movement can be detected and quantified by

Holistic Simulation of Mobile Robot and Sensor Network Applications Using TrueTime

The RUNES project defines a complex road tunnel scenario involving multiple mobile robots navigating in sensor network environment. In this paper, a TrueTime simulation model of the tunnel scenario is developed. The TrueTime simulator allows concurrent simulation of the physical robots and their environment, the software in the nodes, the radio communication, the network routing, and the ultra-sou

The influence of NO on the occurence of autoignition in the end-gas of SI-engines

Full-cycle simulations of a spark ignition engine running on a primary reference fuel have been performed using a two-zone model. A detailed kinetic mechanism is taken into account in each of the zones, while the propagating flame front is calculated from a Wiebe function. The initial conditions for the unburned gas zone were calculated as a mixture of fresh gas and rest gas. The composition of th

A Tide of Cash: Corporate Governance and the Management of Large Cash Windfalls

In this paper we revisit the contentious issue of whether corporate governance arrangements influence corporate cash holdings. We use the exogenous cash windfalls in the oil industry during the 2000s to test the power of three governance dimensions (managerial entrenchment, board independence and ownership) in explaining differences in cash management policies. Between 2000 and 2008 the oil price
