Impact of Intrapartum Events on EFM

2021
The FHR may be affected by maternal factors, fetal factors, and multiple external factors during labor. The EFM reflects both common characteristics and those particular to a specific pregnancy, which vary from case to case. Various monitoring results must be interpreted and processed based on the clinical situation to identify any possible trend of ...

EFM: A Model for Educational Game Design

2008
The research and development of educational game in our country is still in a primary stage, and effective models and ideas for educational game design are of great lack. The educational game can not only be considered as a kind of instructional media, but also as a games-learning environment.

Evidenzbasiertes Fundraising-Management (EFM)

2020
Evidenzbasiertes Fundraising-Management (EFM) setzt sich zum Ziel, die haufig auf Intuition und personlichen Praferenzen beruhenden Entscheidungen im Fundraising-Management dahingehend zu erweitern, dass wissenschaftliche Erkenntnisse und insbesondere empirische Belege in die Entscheidungsfindung um die geeignete Strategie oder Methode integriert ...

Piezoelectric position sensor for ultrasonic EFM motors

Sensors and Actuators A: Physical, 1994
Abstract In the last few years, attempts have been made to miniaturize ultrasonic motors by using silicon micromachining techniques. In particular, the motion of small plates or the rotation of lenses using travelling waves on thin piezoelectric activated diaphragms has been observed.

Mechanisms of Bioleaching and the Visualization of these by Combined AFM & EFM

Advanced Materials Research, 2009
The understanding of mechanisms, by which microorganisms are effecting the dissolution of metal sulfides, what in general is called bioleaching, has progressed largely during the last 15 years. Whereas in the beginning of the nineties of the last century the direct and the indirect mechanisms were state of the knowledge, nowadays it is generally ...

EFM (Eight to Fourteen Modulation)

1986
Compact audio disc uses the bit modulation method NRZ-I. To prevent the introduction of a dc component, bit patterns with large numbers of consecutive logic 0s should be avoided. However all 16-bit combinations are used in quantization of the audio signal, including those with high numbers of consecutive logic 0s. EFM converts the 16-bit words to avoid

HK-EFM and HK-SQ-DDSM

2011
In this chapter, we show how cycle length maximization through architecture modification can be applied to two important classes of multi-bit modulators, namely higher order Error Feedback Modulators (EFMs) and Single-Quantizer DDSMs (SQ-DDSMs).

A new design of EFM constrained codes

IEEE Transactions on Magnetics, 1995
A rate 8/15(2,10) constrained code with 5 encoding states is designed in this paper. This code is of particular interest in recording systems, achieving more than 98% coding efficiency. Its encoding FSTD has five states. Its state-independent decoder has a decoding window of 2, requiring current codeword and one look-ahead codeword to decode current ...

AFM & EFM study on attachment of acidophilic leaching organisms

Hydrometallurgy, 2010
Abstract Bioleaching is the dissolution of metal sulfides by bacterial oxidation processes such as pyrite (FeS2) and chalcopyrite (CuFeS2). It is well known that attachment of leaching bacteria to the mineral surface enhances the metal sulfide dissolution.

Micromachined piezoelectric elastic force motor (EFM)

Proceedings IEEE Thirteenth Annual International Conference on Micro Electro Mechanical Systems (Cat. No.00CH36308), 2002
This paper will focus on the fabrication and characterization of two types of piezoelectric motors based on the elastic force motor principle. The initial motivation for this work was the development of a motor for wristwatch applications, combining high torque (1 /spl mu/m) with low power consumption (10 /spl mu/W) and small dimensions.
