Pattern-based signal/noise separation is a common technique to suppress multiples. It can be formulated in the t x domain using non-stationary Prediction Error Filters (PEF). One can obtain a kinematically correct model of the multiples by downward continuation. The CMP gather and the corresponding multiple estimate are characterized by a space varying PEF. After applying a simple separation te...

Gelatin is considered as a partially degraded product of collagen and it is a biodegradable polymer which can be used to produce scaffolds for tissue engineering. Three-dimensional, porous gelatin scaffolds were fabricated by thermally induced phase separation and freeze-drying method. Their porous structure and pore size were characterized by scanning electron microscopy. Scaffolds with differ...

Common-mode choke (CMC) plays an important role in suppressing the leakage current produced during operation of pulse width modulation (PWM) inverters. However, when common-mode path exhibits a large series stray capacitance, particularly capacitance by long shielded cables, CMC core reaches magnetic saturation. This paper presents technique selecting suitable carrier frequency for inverter to ...

The use of differential voltage measurements is widely used in EIT instruments. Instrumentation amplifiers are always affected by common mode voltages at their input. These voltages may have different origins, being the current sources and multiplexers the ones which contribute the most. However, even considering ideal current sources and multiplexers, some amount of common mode voltage will al...

Electrokinetic techniques are a staple of microscale applications because of their unique ability to perform a variety of fluidic and electrophoretic processes in simple, compact systems with no moving parts. Isotachophoresis (ITP) is a simple and very robust electrokinetic technique that can achieve million-fold preconcentration and efficient separation and extraction based on ionic mobility. ...

Elastic wave propagation in anisotropic media is well represented by elastic wave equations. Modeling based on elastic wave equations characterizes both kinematics and dynamics correctly. However, because P and S modes are both propagated using elastic wave equations, there is a need to separate P and S modes to obtain clean elastic images. The separation of wave modes to P and S from isotropic...

In this paper, a novel method for linear normal mode identification based on Blind Source Separation (BSS) is introduced. Modal coordinates are considered as a specific case of sources that have certain time structure. This structure can be identified by many BSS algorithms. However, algorithms based on second order statistics are particularly suited for the linear normal mode identification. T...

Large-volume sample stacking using the electroosmotic flow (EOF) pump technique has been investigated for the quantification of 3-nitrotyrosine in urine of diabetic rats. The best separation conditions for these highly complex samples were obtained using capillary electrophoresis (CE) in the reversed polarity mode (i.e., injecting at the cathode and detecting at the anode) using cetyltrimethyla...

Abstract– In this paper, we present a new technique for separating two speech signals received from one microphone or one communication channel. In this special case, the separation problem is too ill-conditioned to be handled with common blind source separation techniques. The proposed technique is a generalized approach to model-based speaker-dependent single channel speech separation techniq...
