Selected Aspects of Wireless Communication between Nano-devices

Recently, the concept of a nanonetwork has attracted large attention of researchers as it potentially offers low-cost solutions for a wide spectrum of current applications and enables numerous emerging ones. At present, however, all the sensor networks consist of a relatively small number of macroscale devices with their positions carefully pre...

Source positioning in a large-scale tiny-sensor network of arbitrary topology

To effectively localise a source node in a dense wireless tiny-sensor network with an arbitrary 2D/3D node distribution, a novel approach suitable to describe the hop progress of source-to-sink path in such a system is proposed. In this approach, the network topology is described as a regular lattice and relates the statistical parameters of the...

Multi-scale Fracture Analysis from an Outcrop Analogue: A Case Study from the Cambro-Ordovician Sequence in Petra, Jordan

Natural fractures occur over several orders of size magnitude. Accurately predicting the three-dimensional and multi-scale distribution of fractures in subsurface reservoirs is very difficult. Direct observations are limited to large-scale faults visible on seismic data and high-resolution, mostly small-scale, measurements of fractures...

The Sensitivity of the 3D Connectivity in a Multi-Scale Fracture Network to Variations in Distribution Parameters: A Case Study from Petra, Jordan

The behavior of naturally fractured reservoirs is very different from that of conventional reservoirs. In order to develop a successful production strategy it is important to understand this behavior. Golder Associates developed a software package to model heterogeneous and fractured rock masses. FracMan generates three-dimensional fracture...
