Análisis de arco eléctrico y reduccióon DE energía incidente en una planta de refinación
En este artículo se presentan los resultados obtenidos del análisis de arco eléctrico realizado para el sistema eléctrico de una refinería. Se consideran los estudios de corto circuito, de coordinación de protecciones de sobrecorriente y los criterios establecidos en la NFPA 70E y el IEEE1584. Se presentan los valores…
Advances in in vitro detection of cytotoxicity induced by silver nanoparticles
Silver nanoparticles (AgNPs) are widely used in the fields of biology and medicine because of their excellent optical, electrical and antimicrobial properties. AgNPs can induce cytotoxicity in various cells and organisms, which might be helpful to combat diseases. However, the biohazardous nature of AgNPs is a serious…

Novel meta-surfaces for the design of broadband highly directive antennas
Novel meta-surfaces for designing broadband highly directive Fabry-Perot type antennas are presented. The proposed structure is based on novel optimized multi-layer periodic surfaces that create multiple sub-wavelength cavities with enhanced bandwidth performance. Two double-layer periodic arrays of dissimilar dimensi…

Method for estimation of structural composition of skin layers based on light propagation simulation for liposuction applications
Skin surface irregularity is the most common side effect after liposuction. To reduce this, it is necessary to devise a systematic method to provide structural composition details of skin layers, such as fat thickness and fat boundary tilt angle, for the plastic surgeon. Several commercial portable devices are availab…
Gain of 56 in graphene silicon carbide schottky collector phototransistor (GSCBT) for radiation detection
Large low atomic number (Z) windows for novel solid state radiation detection schemes can be conceived by implementation of graphene semi-metal rectifying contacts on SiC epilayers and substrates. The low absorption of Graphene epilayers increases the incident flux/energy to the space charge region increasing detector…
Traceability of impulse test for diagnostic measurements of power apparatus
This paper describes the diagnostic measurements involved while performing impulse tests. For most applications during impulse tests, the impulse voltage and impulse current are measured. Because of the nature of impulse test it is very common that Electro Magnetic Interference signals (EMI) are generated. This EMI wi…
Morphology change of α-Fe2O3 nanocubes induced by thermal treatments: GISAXS study
GISAXS has been used to study thermally induced morphology change of submonolayer α-Fe2O3nanocubes coated on Si(100) substrate. While morphology of nanocube was intact after annealing at 400 °C in vacuum, ambient environment annealing at the same temperature altered morphology of nanocube toward a more rounded shape.…

Spatial sorting and routing of electromagnetic waves based on polarization control
The polarization of a plane wave in free space is used to control the excitation and the directionality of a guided electromagnetic wave. Experiments are conducted using a two-dimensional waveguide made of two parallel aluminum plates which is externally excited. The upper plate, which has a linear array of holes, is…

Stimulating and detecting changes in the insulation health state of inverter fed ac machines
In modern traction drive applications condition monitoring is getting more and more important. Insulation health state monitoring can be done by evaluating the high frequency current response to voltage step excitation by the signal analyses of the current sensors, which are also used for the control of the machine. T…
