Vanishing Properties of Dual Bass Numbers [PDF]

open access: yesAlgebra Colloquium, 2014
Let R be a Noetherian ring, M an Artinian R-module, and 𝖒 ∈ Cos RM. Then cograde R𝔭 Hom R (R𝔭,M) = inf {i | πi(𝔭,M) > 0} and [Formula: see text] where πi(𝔭,M) is the i-th dual Bass number of M with respect to 𝔭, cograde R𝔭 Hom R (R𝔭,M) is the common length of any maximal Hom R (R𝔭, M)-quasi co-regular sequence contained in 𝔭 R𝔭, and fd R𝔭 Hom R (R𝔭,

Impact of PWM strategies on RMS current of the DC-link Voltage Capacitor of a dual-three phase drive [PDF]

open access: yes, 2014
The major drawback of usual dual three-phase AC machines, when supplied by a Voltage Source Inverter (VSI), is the occurrence of extra harmonic currents which circulate in the stator windings causing additional losses and constraints on the power ...

Combustion and emission characteristics of dimethyl ether/gasoline DFSI engine under different excess air coefficients

open access: yesCase Studies in Thermal Engineering, 2023
Dimethyl ether (DME) was a carbon neutral alternative fuel for engines.The combustion and emission characteristics of a DME/gasoline Dual Fuel Spark Ignition (DFSI) engine with various excess air coefficients (λs) at different DME ratios (ΦDME) were ...

Hyper dual number matrices

open access: yes, 2023
We study hyper dual numbers and hyper dual number matrices. Firstly, we give some basic properties of dual numbers and hyper dual numbers. Next, we investigate hyper dual number matrices using the properties of dual number matrices.

Use of dual in standard Slovene, colloquial Slovene and Slovene dialects

open access: yesLinguistica, 2012
The dual is a grammatical expression of number in some languages (e.g. Slovene, Sorbian or Modern Standard Arabic) that denotes two persons or objects. In modern Indo-European languages, the dual is an archaism and one that has been preserved only in a ...

Dual number and the typology of the numeral-noun construction

open access: yesCatalan Journal of Linguistics, 2020
In this paper I propose an extension of Martí’s (2020a) theory of the numeral+noun construction (e.g., English three dogs) to languages whose nouns distinguish singular, dual and plural.

Differential contributions of set-shifting and monitoring to dual-task interference [PDF]

open access: yes, 2012
It is commonly argued that complex behaviour is regulated by a number of “executive functions” which work to co-ordinate the operation of disparate cognitive systems in the service of an overall goal.

Discovering Copy Number Variation in Dual-Purpose XinJiang Brown Cattle

open access: yesFrontiers in Genetics, 2022
Copy number variants (CNVs), which are a class of structural variant, can be important in relating genomic variation to phenotype. The primary aims of this study were to discover the common CNV regions (CNVRs) in the dual-purpose XinJiang-Brown cattle ...

Direct torque control for dual three-phase induction motor drives [PDF]

open access: yes, 2004
A direct torque control (DTC) strategy for dual three-phase induction motor drives is discussed in this paper. The induction machine has two sets of stator three-phase windings spatially shifted by 30 electrical degrees.
