Resonant Absorption in GaAs-Based Nanowires by Means of Photo-Acoustic Spectroscopy
Semiconductor nanowires made of high refractive index materials can couple the incoming light to specific waveguide modes that offer resonant absorption enhancement under the bandgap wavelength, essential for light harvesting, ...
Damped Posterior Linearization Filter
In this letter, we propose an iterative Kalman type algorithm based on posterior linearization. The proposed algorithm uses a nested loop structure to optimize the mean of the estimate in the inner loop and update the ...
GaSb superluminescent diodes with broadband emission at 2.55 μ m
We report the development of superluminescent diodes (SLDs) emitting mW-level output power in a broad spectrum centered at a wavelength of 2.55 μm. The emitting structure consists of two compressively strained GaInAsSb/G ...
Design, synthesis, and structure-property relationships of Er3+ -doped TiO2 luminescent particles synthesized by sol-gel
Titania particles doped with various concentrations of Erbium were synthesized by the sol-gel method followed by different heat treatments. The shape and the grain growth of the particles were noticeably affected by the ...
Spin filtering in silicene by edges and chemically or electrically induced interfaces
Silicene is a graphene-like material with relatively strong spin-orbit coupling exhibiting gapless topologically protected edge states. In addition, it has a buckled structure, and hence, it stands as a feasible candidate ...
Analysing and Improving Student's Mathematics Skills using ICT-tools
In this paper the supportive actions taken at Tampere University of Technology (TUT) for the first year students in engineering mathematics are discussed. The measures include Basic Skill’s Test (BST), Mathematics Remedial ...
In vitro characterization of arylhydrazones of active methylene derivatives
Arylhydrazones of active methylene compounds (AHAMCs) are potent chemotherapy agents for the cancer treatment. AHAMCs enhance the apoptotic cell death and antiproliferation properties in cancer cells. In this study, a ...
Digital Predistortion in Large-Array Digital Beamforming Transmitters
In this article, we propose a novel digital predistortion (DPD) solution that allows to considerably reduce the complexity resulting from linearizing a set of power amplifiers (PAs) in single-user large-scale digital ...
Learning from Demonstration for Hydraulic Manipulators
This paper presents, for the first time, a method for learning in-contact tasks from a teleoperated demonstration with a hydraulic manipulator. Due to the use of extremely powerful hydraulic manipulator, a force-reflected ...
Transport Triggered Polar Decoders
In this paper, the first transport triggered architecture (TTA) customized for the decoding of polar codes is proposed. A first version of this programmable processor is optimized for the successive cancellation (SC) ...
