Synthesis of single-wavelength temporal phase-shifting algorithms (PSA) for interferometry is well-known and firmly based on the frequency transfer function (FTF) paradigm. Here we extend the single-wavelength FTF-theory to dual and multi-wavelength PSA-synthesis when several simultaneous laser-colors are present. The FTF-based synthesis for dual-wavelength (DW) PSA is optimized for high signal...

Fig. 3. DWSI of rat brain using (a) DW-EPSI and (b) DW-LSEPSI. The left images show NAA maps and the right graphs show average spectra in the red rectangles in the left images. Yellow lines in the left images show edges of a rat head. (c) ADC map of NAA using DW-LSEPSI. Color represents ADC value. Fig. 1. Sequence diagram of DW-LSEPSI.

Developing a data warehouse (DW) is a complex, time consuming and prone to fail task. Different DW models and methods have been presented during the last few years. However, none of them addresses the whole development process in an integrated manner. In this paper, we present a DW development method, based on the Unified Modeling Language (UML) and the Unified Process (UP), which addresses the...

The paper presents a: a) brief overview and analysis of existing approaches to the data warehouse (DW) evolution problem, and b) detailed description of the research idea for the DW evolution problem (primarily intended for structured data sources and realizations with relational database engines). We observe the DW evolution problem as a double issue from the DW perspective, and from the maste...

A data warehouse (DW) provides information from external data sources for analytical processing, decision-making, and data mining tools. External data sources are autonomous, i.e. they change over time, independently of a DW. Therefore, the structure and content of a DW has to be periodically synchronized with its external data sources. This synchronization concerns DW data as well as schema. C...

The interaction mechanism between transverse domain walls TDWs in Permalloy nanowires and artificially patterned traps is studied using high-sensitivity spatially resolved magneto-optical Kerr effect measurements and numerical simulations. T-shaped trap geometries are considered, where a DW traveling in the horizontal arm is pinned by the vertical arm. Pinning strengths as well as potential ene...

We have experimentally studied micrometer-scale domain wall (DW) motion driven by a magnetic field and an electric current in a Co/Pt multilayer strip with perpendicular magnetic anisotropy. The thermal activation energy for DW motion, along with its scaling with the driving field and current, has been extracted directly from the temperature dependence of the DW velocity. The injection of DC cu...

BACKGROUND Coronal diffusion-weighted magnetic resonance imaging (DW-MRI) and apparent diffusion coefficient (ADC) values have gradually become applied (following conventional axial DW-MRI) in the renal analysis. To explore whether data obtained using coronal DW-MRI are comparable with those derived using axial DW-MRI, this preliminary study sought to assess the agreement in renal ADC values be...
