Fully-differential log-domain integrator with orthogonal common-mode and differential-mode responses

Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03., 2003
In this paper, an all NPN fully-differential log-domain integrator is proposed. The common-mode response of the proposed integrator, unlike those of the previously reported ones, is linear and independent on differential signal. This makes the proposed integrator less susceptible to the variations of the common-mode signal than its predecessors ...

Differential mode delay diagnostics for LP modes traversing a few-mode fiber

Applied Optics, 2021
We provide differential mode delay (DMD) diagnostics for linearly polarized (LP) modes traversing a few-mode fiber (FMF). We employ a modal interferometer method with a butt coupling mechanism to measure the DMD between any two modes guided in FMFs with step-index (SI) and depressed-cladding profiles. The measurement principle is based on investigating

Common-mode and differential-mode analysis of common-mode chokes

2003 IEEE Symposium on Electromagnetic Compatibility. Symposium Record (Cat. No.03CH37446), 2004
In this paper, three methods for the measuring common-mode and differential-mode S-parameters of common mode chokes are presented. The three methods involved: (1) ABCD chain matrix; (2) using hybrid couplers; and (3) modal decomposition. Each measurement method provides a specific level of accuracy. The modal decomposition method can work up to 10 GHz.

Sliding Mode Control and Differential Algebra

IFAC Proceedings Volumes, 1992
Summary Sliding mode control of nonlinear systems is reformulated from a differential algebraic perspective. Input-dependent sliding surfaces, possibly including time derivatives of the input signal, naturally arise from elementary differential algebraic results as applied to nonlinear controlled systems. This viewpoint directly leads to consider the

Sliding-Mode-Based Differentiation and Filtering

IEEE Transactions on Automatic Control, 2018
The proposed $k$ th-order filter is based on sliding modes (SMs). It exactly estimates $k$ input derivatives in the absence of noises, and is robust to noises of small magnitudes or having small average values. Estimation accuracy asymptotics are calculated.

Modes of differentiation in children’s writing construction

European Journal of Psychology of Education, 1988
In this paper we aim at analyzing the modes of differentiation in children’s writing development during the presyllabic phase that, in the theoretical framework developed by Ferreiro and Teberosky, comes before the discovery of sound correspondance.

Situational Modes of Differentiation

2020
In this chapter, the author introduces the concept of situational modes of differentiation. These modes cut across categories such as migrant or foreigner, or dimensions such as religion or gender. They are not thought of as universal although it is assumed that they work within situations across time and space.

Differential Mode of Justice

2019
In the discussion above, I have divided the authority to solve disputes in rural community into four types. Among the four types, there are the authority of village administration and the authority of court, which are both in the category of institutionalized authority.

Differentiation of Renal Masses Using A-Mode Ultrasound

Journal of Urology, 1971
SummaryA unique property of ultrasound is its ability to differentiate between cystic and solid masses. Using nephrosonography, 150 renal masses were examined. In 144 of them (96 per cent), the physical state of the mass, that is fluid, solid or complex, was correctly predicted. Nephrosonography is uncomplicated, atraumatic and safe.
