CiNetView - Graphic Interface for Wireless Sensor Network Deployment and Monitoring
2010
Reliable communication is crucial for successful deployment of a wireless sensor network. Many environmental factors can affect the performance of radio links, and the deployment of a network without real-time information about link qualities can be a demanding task. This paper describes the CiNetView application that is intended to support the deployment and monitoring of wireless sensor network. CiNetView is based on diagnostic information collected by sensor nodes, and it allows the user to see a graphical presentation of the network topology and to monitor the network diagnostic information in real time.
Governance through Economic Paradigms: Addressing Climate Change by Accounting for Health
2016
"Climate change is a major challenge for sustainable development, impacting human health, wellbeing, security, and livelihoods. While the post-2015 development agenda sets out action on climate change as one of the Sustainable Development Goals, there is little provision on how this can be achieved in tandem with the desired economic progress and the required improvements in health and wellbeing. This paper examines synergies and tensions between the goals addressing climate change and economic progress. We identify reductionist approaches in economics, such as 'externalities', reliance on the metric of the Gross Domestic Product, positive discount rates, and short-term profit targets as so…

Distribution of Albian clastic deposits in the Benguela basin (Angola): evidence of a Benguela palaeocurrent?
2009
Abstract The Albian clastic Tuenza Formation of the Benguela basin (south Angola) is described and its geographic distribution analysed in detail. From these observations, the existence of an Albian “PalaeoBenguela current” is proposed. This would imply that a marine longshore current reworked the sand transported by palaeorivers and settled it northward along the coast of the young Atlantic Ocean (during the Albian). A parallel between Albian clastic deposits and the modern sediments deposited by the Benguela current is drawn, focusing on the striking resemblance between the two currents, i.e. the actual Benguela current and the Albian marine current, and the associated sedimentary bodies.
A Personal LPWAN Remote Monitoring System
2021
Firefighters are equipped with an immobility detector device also called the Personal Alert Safety System (PASS) that is integrated into the user's Self-Contained Breathing Apparatus (SCBA). If a firefighter remains motionless for a certain period of time, a loud audible alert is triggered to notify the Firefighter Assist and Search Team (FAST) deployed in the area of intervention that the wearer of the PASS device is in trouble and in need of rescue. However, this device is not reliable enough since it triggers frequently false positives which lead to developing a tolerance for sounding alarms among the crew. As a consequence, they do not seem to be concerned about it as they should and th…
Endogenous Growth, Capital Utilization and Depreciation
2004
We study the one sector model of growth when a linear production technology is combined with adjustment costs and a technology for capital maintenance. Agents are allowed to under-use the installed capital and to vary the depreciation rate. This economy decides endogenously how much resources devotes to the accumulation of new capital and how much to maintenance and repair activities. We find as striking results that the long-run depreciation and capital utilization rates are positively related to the population growth rate, and that both depend negatively on the intial conditions. The long-run growth rate appears positively correlated with the depreciation rate.
Throwing the Spanner in the Works: The Mixed Blessing of FDI
2014
FDI is generally attributed to have positive impact for developing countries. In contrast, this paper shows that foreign capital inflows may cause an economy to be stuck in a middle-income trap. Introducing a simple capital market imperfection into a standard neoclassical (open-economy) model of growth, I show that FDI crowds out domestic investment when countries are still growing. If profitable investments are pursued by foreign capital owners, this does reduce chances for domestic entrepreneurs that they would have otherwise been able to take, by means of economy-wide savings. The long term losses due to the crowding-out effect occur despite the short-term gains that sudden capital inflo…

On the generalization of the Boltzmann equation
1974
Starting from the Liouville equation and making use of projection operator techniques we obtain a compact equation for the rate of change of then-particle momentum distribution function to any order in the density. This equation is exact in the thermodynamic limit. The terms up to second order in the density are studied and expressions are given for the errors committed when one makes the usual hypothesis to derive generalized Boltzmann equations. Finally the Choh-Uhlenbeck operator is obtained under additional assumptions.
