Energy Consumption Comparison Between Macro-Micro and Public Femto Deployment in a Plausible LTE Network

Jean-Yves Le Boudec, Ramin Khalili, Miroslav Popovic

We study the energy consumptions of two strategies that increase the capacity of an LTE network: (1) the deployment of redundant macro and micro base stations by the operator at locations where the traffic is high, and (2) the deployment of publicly access ...

Low temperature pyrex/silicon wafer bonding via a single intermediate parylene layer

Martinus Gijs, Ata Tuna Ciftlik

We introduce a new low temperature (280 °C) parylene-C wafer bonding technique, where parylene-C bonds directly a Pyrex wafer to a silicon wafer with either a Si, SiO2 or Si3N4 surface with a bonding strength up to 23 MPa. The technique uses a single layer ...

Reduction of the phosphorous cross-contamination in nip solar cells prepared in a single-chamber PECVD reactor

Christophe Ballif, Franz-Josef Haug, Laurent Fabien Hubert Sansonnens

A new approach to reduce phosphorous contamination in the intrinsic layer during the deposition of amorphous silicon (a-Si:H) nip solar cells prepared in single-chamber reactors is presented. This novel process consists of a hydrogen etching plasma perform ...

Low-loss polymer waveguides on nanoporous layers

Libero Zuppiroli, Rolando Ferrini, Gaëtan Wicht

Multimode planar polymer waveguides were fabricated on hybrid polymer nanoporous layers with a fast industrial aqueous-based method well adapted to coat large-surface plastic substrates and easily scalable up to economical mass production volumes. Using a ...

Graphene: Substrate preparation and introduction

Henning Paul-Julius Stahlberg, Radosav Svetozara Pantelic

This technical note describes the transfer of continuous, single-layer, pristine graphene to standard Quantifoil TEM grids. We compare the transmission properties of pristine graphene substrates to those of graphene oxide and thin amorphous carbon substrat ...

Efficient Image Reconstruction Under Sparsity Constraints With Application To Mri And Bioluminescence Tomography

Michaël Unser, Matthieu Guerquin-Kern, Jean-Charles Baritaux

Most bioimaging modalities rely on indirect measurements of the quantity under investigation. The image is obtained as the result of an optimization problem involving a physical model of the measurement system. Due to the ill-posedness of the above problem ...

A 0.24-nJ/bit Super-Regenerative Pulsed UWB Receiver in 0.18-mu m CMOS

Catherine Dehollain, Michel Declercq

This paper describes a receiver system design for impulse-radio ultra-wideband (IR-UWB) that operates at two carrier frequencies-3.494 and 3.993 GHz-with a 10-Mbps data rate. To reduce the power consumption of the front-end amplifiers, a super-regenerative ...

Physical and numerical modeling of the spillways and plunge pools of Koman Dam in Albania

Anton Schleiss, Giovanni De Cesare, Gaël Epely Chauvin, Matteo Paolo Elia Antonio Federspiel, Milad Daneshvari, Mathias Malquarti

The 115 m high Koman Dam is located in the northern part of Albania and is part of the Drin River hydroelectric cascade. The dam is equipped with two tunnel spillways with flip buckets at their downstream limits. Two large scour holes were created in the d ...
