Intellectual property related development aid: is supply aligned with demand?

We assessed to what extent developed country development aid programmes are likely to have interacted with, and potentially contributed to the promotion of country-appropriate sustainable changes in IP strategies and technological capacities over the period 2005-10. This was done primarily on the basis of an imputed impact assessments of four emerging and transition economies; namely Brazil, India, Poland and Thailand. Through an analysis of various measures of the domestic economic, technological and Intellectual Property context, we studied to what extent the supply of IP-related development aid provided between 2005 and 2010 responded to the likely needs of recipient countries. While the data shows that technical and financial assistance in this area could be of great use, and there is clearly a need for well-targeted IP TA and much scope for useful IP TA interventions, there seemed to only be a partial alignment between country needs and the direction of IP TA. On the whole, most IP-related development aid and technical assistance ended to focus on similar areas in each country, regardless of the development context. In Brazil and India’s case, training on IP administration may have influenced increased efficiency (from a low base) at the INPI and IP India, while the substantial EU support to raise SME IP awareness in Poland is likely to have had some significant impacts. In India, sustained development aid in this area likely influenced legislation on plant variety protection, as did WIPO TA on legislative reforms in Thailand. In all cases, the substantial US (and to a more limited extent EC) focus on development aid directed towards enforcement coincided with improvements in this area, though the political and economic pressures by both providers, and especially the US Section 301 System probably dwarfed the impact of this type of aid. Further, the typology and direction of IP related development aid reflects the comparative advantage of IP TA providers, as well as political and diplomatic interests, trade priorities and colonial ties, among many other things. As such, it is important to understand that IP TA is also highly political – a fact often concealed in the emphasis on its “technical” nature.Intellectual Property and development, aid and technical assistance technological capacities in Brazil, India, Poland, Thailand, taxonomy of development, funding flows Intellectual Property and development, aid and technical assistance technological capacities in Brazil, India, Poland, Thailand, taxonomy of development, funding flows Intellectual Property and development, aid and technical assistance, technological capacities in Brazil, India, Poland, Thailand, taxonomy of development, funding flows Intellectual Property and development, aid and technical assistance technological capacities in Brazil, India, Poland, Thailand, taxonomy of development, funding flows

Oscillatory motion of a droplet in an active poroelastic two-phase model

We investigate flow-driven amoeboid motility as exhibited by microplasmodia of Physarum polycephalum. A poroelastic two-phase model with rigid boundaries is extended to the case of free boundaries and substrate friction. The cytoskeleton is modeled as an active viscoelastic solid permeated by a fluid phase describing the cytosol. A feedback loop between a chemical regulator, active mechanical deformations, and induced flows gives rise to oscillatory and irregular motion accompanied by spatio-temporal contraction patterns. We cover extended parameter regimes of active tension and substrate friction by numerical simulations in one spatial dimension and reproduce experimentally observed oscillation periods and amplitudes. In line with experiments, the model predicts alternating forward and backward ectoplasmatic flow at the boundaries with reversed flow in the center. However, for all cases of periodic and irregular motion, we observe practically no net motion. A simple theoretical argument shows that directed motion is not possible with a spatially independent substrate friction

From Monocular SLAM to Autonomous Drone Exploration

Micro aerial vehicles (MAVs) are strongly limited in their payload and power capacity. In order to implement autonomous navigation, algorithms are therefore desirable that use sensory equipment that is as small, low-weight, and low-power consuming as possible. In this paper, we propose a method for autonomous MAV navigation and exploration using a low-cost consumer-grade quadrocopter equipped with a monocular camera. Our vision-based navigation system builds on LSD-SLAM which estimates the MAV trajectory and a semi-dense reconstruction of the environment in real-time. Since LSD-SLAM only determines depth at high gradient pixels, texture-less areas are not directly observed so that previous exploration methods that assume dense map information cannot directly be applied. We propose an obstacle mapping and exploration approach that takes the properties of our semi-dense monocular SLAM system into account. In experiments, we demonstrate our vision-based autonomous navigation and exploration system with a Parrot Bebop MAV
