Latitude error in compass deviation: mathematical method to determine the latitude error in magnetic compass deviation
(Gdansk University of Technology, 2014-10)
This article aims to provide the seafarer with a tool to calculate the deviation for a righted ship in any geographical
position using only the information available on board. In this way the accidental errors in the ...
Task-modality and L1 use in EFL oral interaction
(Sage, 2014-07-21)
[EN] This study examines whether task-modality (speaking vs. speaking+writing) influences first language (L1) use in task-based English as a foreign language (EFL) learner–learner interaction. Research on the topic has ...
Large size FFTs over time-varying channels
(IET, 2014-06-01)
[EN] In orthogonal frequency division multiplexing (OFDM) signals, the usage of large size fast Fourier transforms (FFTs) reduces the guard interval percentage, and therefore increases the data throughput reducing the data ...
Experimental Study of the Response of Efficient Lighting Technologies to Complex Voltage Fluctuations
(Elsevier, 2014-07-09)
The replacement of incandescent lamps with more energy-efficient lighting technologies has a direct influence on the way flicker is measured. The International Electrotechnical Commission (IEC) established in the 61000-4-15 ...
Integrating stakeholders’ demands and scientific knowledge on ecosystem services in landscape planning
(Springer, 2014-02-07)
The conflict between conservation and timber production is shifting in regions such as Biscay (Basque Country, northern Spain) where planted forests are no longer profitable without public subsidies and environmentalist ...
Energy and economic assessment of the envelope retrofitting in residential buildings in Northern Spain
(Elsevier, 2014-10-18)
In this paper, potential energy savings by implementing different energy saving methods to enhance the building envelope are presented and calculated through transient simulations using TRNSYS software. To do that, a ...
A method based on 1H NMR spectral data useful to evaluate the hydrolysis level in complex lipid mixtures
(Elsevier, 2014-10-12)
A new approach is reported, based on Proton Nuclear Magnetic Resonance (1H NMR) spectral data, to study qualitatively and quantitatively the hydrolysis level in complex lipid mixtures. It is based on a detailed study of ...
La gestión de la sexualidad en parejas con ideología igualitaria. De la monogamia dada por sentada a la negociación
(Universidade de Santiago de Compostela, 2014-07-14)
Este artículo es parte de una investigación cualitativa con parejas de ideología paritaria sobre los nuevos modelos de pareja y de gestión de la relación. Concretamente, se tratará la cuestión de la gestión y la negociación ...
Enantioselective Construction of Tetrasubstituted Stereogenic Carbons through Brønsted Base Catalyzed Michael Reactions: α´-Hydroxy Enones as Key Enoate Equivalent
(ACS, 2014-11-25)
Catalytic and asymmetric Michael reactions constitute very powerful tools for the construction of new C–C bonds in synthesis, but most of the reports claiming high selectivity are limited to some specific combinations of ...
An Alternative Strategy to Improve the Flicker Severity Measurement
(Elservier, 2014-07-12)
The IEC 61000-4-15 standard defines a flickermeter that is universally accepted as the meter used for the objective measurement of a disturbing light flicker. The accurate results provided by the IEC flickermeter under ...
