    Interference Functionals in Poisson Networks

    The authors propose and prove a theorem that allows the calculation of a class of functional on Poisson point processes that have the form of expectations of sum-products of functions. In proving the theorem, they extend the Campbell-Mecke theorem from stochastic geometry. They proceed to apply their result in the...

    Connectivity Versus Area Coverage in Unmanned Aerial Vehicle Networks

    The authors investigate the area coverage and connectivity of an autonomous, Unmanned Aerial Vehicle (UAV) network, whose goal is to monitor and sense a given area of interest in an efficient manner. To this end, they propose a connectivity-based mobility model that aims to sustain connectivity between the UAVs and...

    A Statistical Transmit Power Allocation Scheme for Spatially Correlated MIMO Systems and Its Robustness to Estimation Errors

    The authors consider a simple statistical transmit power allocation scheme for spatially correlated Multiple-Input Multiple-Output (MIMO) systems, which is based on the Karhunen-Loueve transform. The considered scheme is solely based on second-order channel statistics, i.e., no instantaneous channel knowledge is required at the transmitter. They consider different transmit power allocation...

    Foreign Acquisitions, Domestic Multinationals, And R&D

    The aim of this paper is to evaluate the causal effect of foreign acquisition on R&D intensity in targeted domestic firms. The authors are able to distinguish domestic multinationals and non-multinationals, which allows one to investigate the fear that the change in ownership of domestic to foreign multinationals leads to...

    Automatic Layout and Structure-Based Editing of UML Diagrams

    Graphical modeling languages, as defined in the UML, are appealing in their relative ease of comprehension. A well-structured model can provide a compact representation of complex designs. However, the development of graphical models is still hampered by modeling tools that force the user to perform low-level graphical editing steps, instead...

    Selecting a Spatially Efficient Cooperative Relay

    Cooperative relaying is a communication technique in wireless networks where neighboring nodes assist communication pairs to mitigate the negative effects of multi-path fading. The resulting performance strongly depends on the selected relays. Although a cooperative relay provides benefits to a given source-destination pair, overall network performance might be degraded due...

    Interfacing with Virtual Worlds

    Virtual worlds (often referred to as 3D3C for 3D visualization & navigation and the 3C's of Community, Creation and Commerce) integrate existing and emerging (media) technologies (e.g. instant messaging, video, 3D, VR, AI, chat, voice, etc.) that allow for the support of existing and the development of new kinds of...

    Foreign Acquisition, Plant Survival, And Employment Growth

    This paper analyses the effect of foreign acquisition on survival probability and employment growth of target plant using data on Swedish manufacturing plants during the period 1993- 2002. An improvement over previous studies is that the authors take into account firm level heterogeneity by separating the targeted plants into those...
