Design methodology for a maximum sequence length MASH digital delta-sigma modulator [PDF]

open access: yes, 2009
The paper proposes a novel structure for a MASH digital delta-sigma modulator (DDSM) in order to achieve a long sequence length. The expression for the sequence length is derived. The condition to produce the maximum sequence length is also stated. It is

Histone H1e Interacts with Small Hepatitis Delta Antigen and Affects Hepatitis Delta Virus Replication [PDF]

open access: yes, 2011
Hepatitis delta virus (HDV) encodes two isoforms of delta antigens (HDAgs ). The small form of HDAg (SHDAg) is required for HDV RNA replication, while the large form of HDAg ( LHDAg) is required for viral assembly.

Iterative solution of elliptic equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
We reduce solution of the Dirichlet problem ($x \in D \subset R^m$) \[ \Delta u(x)+a(x)u(x)=f(x) \quad \mbox{in $D$}, \qquad u=0 \quad \mbox{on $\partial D$} \] to iterative solution of a simpler problem \[ \Delta u=f(x) \; \; \mbox{in $D$}, \; \; u=0

Delta modulation techniques for low bit-rate digital speech encoding [PDF]

open access: yes, 1985
Includes bibliography.Two new hybrid companding delta modulators for speech encoding are presented here. These modulators differ from the Hybrid Companding Delta Modulator (HCDM) proposed by Un et al in that the two new encoders employ Song Voice ...

Mathematical Explanation and Fault Diagnosis of Low Delta-T Syndrome in Building Chilled Water Systems

open access: yesBuildings, 2018
Low delta-T syndrome often occurs in building chilled water systems, which makes systems fail to operate as efficiently as originally anticipated. Extensive studies have been conducted on the subject of low delta-T syndrome with the aims of investigating
