This work provides a feasibility study on estimating the 3-D locations of several thousand miniaturized free-floating sensor platforms. The localization is performed on basis of sparse ultrasound range measurements between sensor platforms and without the use of beacons. We show that this task can be …

The divide between us and the rest of nature has been attributed to various root causes: the growing disenchantment of the world, the loss of direct experience and lately the replacement of the real with simulations of it. Modernity's move away from the natural world has also generated countervailing …

Standard mass-production is a well-known manufacturing concept. To make small quantities or even single items of a product according to user specifications at an affordable price, alternative agile production paradigms should be investigated and developed. The system presented in this paper is based …

At the biomedical department of the TUDelft a sensor node is designed[1]. This is an Autonomous Wireless Sensor Node(AWSN) with temperature monitoring, which is powered up wirelessly and have data transmission through backscattering. The aim of the project is to design a receiver for the AWSN and to …

The main purpose of this thesis is to analyse Oasis’s future cash flow more accurately by using @Risk. Oasis is a complex Excel tool that has been developed by OfficeSpecialisten in cooperation with one of their clients. Oasis is an analysis tool which analyses future cash flow with the use of macros. …

Europe in general and Romania specifically has been increasingly a target of foreign and domestic investors. Due to its cheap land prices and agricultural policies supporting largescale agricultural investments Romania has become a country with high risks concerning land grabbing. However, the academic …

The goal of this study was to explain various measurements of atmospheric methane on Mars performed by the PFS instrument on-board the European Mars Express mission and from ground based observations. In order to reach this goal a layer of methane was assumed to exist in porous near surface layers of …

The objective of an energy management strategy for fuel cell hybrid propulsion systems is to minimize the fuel needed to provide the required power demand. This minimization is defined as an optimization problem. Methods such as dynamic programming numerically solve this optimization problem. Strategies …

In this study, we present a new light absorption enhancement method for p-i-n thin film silicon solar cells using pyramidal surface structures, larger than the wavelength of visible light. Calculations show a maximum possible current enhancement of 45% compared with cells on a flat substrate. We deposited …

Exposure data available to developers of earthquake loss models are often very crudely aggregated spatially, and in such cases very considerable effort can be required to refine the geographical resolution of the building stock inventory. The influence of the geographical resolution of the exposure data …
