Robust and tunable integrated polarization rotator
(2014-03-11)Integrated polarization rotators suffer from very high sensitivity to fabrication errors. A polarization rotator scheme that substantially increases fabrication tolerances is proposed. In the proposed scheme, two tunable ... -
Analysis of M2M Capabilities in 4G
(2014-05-07)M2M (Machine to Machine) communications enable many new applications that reduce the costs of maintenance and operation via remote monitoring and control. The forecasts for this type of communications predict traffic ... -
IntelCity, comprehensive management platform for smart cities
(2014-05-07)Modern cities contain a wealth of information that is usually scattered among a myriad of organisms. For citizens it is many times difficult and confusing to access this information. Cities must find a way to put all this ... -
Parametric model of spectral envelope to synthesize realistic intensity variations in singing voice
(2014-05-28)In this paper, we propose a method to synthesize the natural variations of spectral envelope as intensity varies in singing voice. To this end, we propose a parametric model of spectral envelope based on novel 4-pole ... -
Polarization management for coherent optical receivers
(2014-06-03)The constant growth of bandwidth requirements in optical communication networks has prompted the evolution from conventional on-off-keying (OOK) transmission techniques to coherent, polarization multiplexed schemes. The ... -
Low-cost step aerobics system with virtual aerobics trainer
(2014-06-30)In this paper a low-cost step-aerobics instructor simulation system is presented. The proposed system analyses a given song to iden- tify its rhythmic pattern. Subsequently, this rhythmic pattern is used in order to ... -
Multimodal image data fusion for Alzheimer’s Disease diagnosis by Sparse Representation
(KES, 2014-07-09)Alzheimer's Diasese (AD) diagnosis can be carried out by analysing functional or structural changes in the brain. Functional changes associated to neurological disorders can be figured out by positron emission tomography ... -
DC-18 GHz MMIC tapered distributed power amplifier
(2014-07-22)A DC-18 GHz MMIC tapered power distributed amplifier has been designed and simulated in GaAs technology. The amplifier has been designed according to the theory for power and efficiency maximization based on tapered drain ... -
First steps towards developing an open access software designed for the recognition of daily microstructures used in ageing fish
(2014-07-29)Ageing methods for most of the exploited fish species are not validated, and consequently age data series often have important gaps and uncertainty manifesting its consequences on age-based fisheries assessment. Amongst ... -
Silicon-on-insulator polarization controller with relaxed fabrication tolerances
(2014-07-31)Polarization control is essential in applications ranging from optical communications to interferometric sensors. The implementation of in- tegrated polarization controllers is challenging as they require polariza- tion ... -
Prestaciones de LTE sobre el canal aeronáutico
(2014-09-03)This work assesses the performance of Long Term Evolution (LTE) downlink over aeronautical channels associated to arrival, parking and en-route scenarios. The huge velocity related to some of these scenarios poses the ... -
Receptor coherente integrado ‘colorless’ de gran margen dinámico basado en un acoplador a 120º
(2014-09-09)Un receptor ‘colorless’ requerirá en su banda de operación de un elevado rechazo en modo común CMRR para reducir eficientemente la interferencia en banda base ocasionada por los canales colindantes al detectado y conseguir ... -
Análisis y diseño de filtros diferenciales basados en líneas acopladas
(2014-09-11)The design of differential bandpass filters using coupled lines is presented. The topology proposed, consisting of short-circuited coupled lines is analyzed by means of analytical equations. The study is carried out by ... -
The Complementary Strip-Slot: From the Unit-Cell of Artificial Transmission Lines to the Basic Element of Novel Antennas
(2014-09-11)The complementary strip-slot radiating element and its applications are reviewed. The element is a modified version of the conventional microstrip-fed slot that presents very broad matching. Its inherent lattice equivalent ... -
