On A Generalization of Small-Injective Modules

Iraqi Journal of Science
        Let R be a ring. JS-injective right R-modules are introduced and studied in  this paper as a generalization of small-injective right R-modules. Let  N and  M be right R-modules.

Principally ss-Supplemented Modules

مجلة بغداد للعلوم
In this paper, we introduce and study the concepts of principally ss-supplemented and principally ss-lifting modules. These two concepts are natural generalizations of the concepts of ss-supplemented and ss-lifting modules.

Pre-Assessment of Radiated Fields from Small Electronic Submodules [PDF]

Radioengineering, 2018
A novel approach to the evaluation of electromagnetic fields radiated from electronic devices by using a small shielded box is presented. Several EMC problems can be identified by employing the computations of a Radiated Model device, such as the model ...

Severe right Ore sets and universal localisation

, 2007
We introduce the notion of a severe right Ore set in the main as a tool to study universal localisations of rings but also to provide a short proof of P. M. Cohn's classification of homomorphisms from a ring to a division ring. We prove that the category

A transfer principle: from periods to isoperiodic foliations

, 2016
In this paper we study the dynamics and topology of the isoperiodic foliation defined on the Hodge bundle over the moduli space of genus $g\geq 2 ...

Analyzes of Flyback DC-DC Converter for Submodule Level Maximum Power Point Tracking in Off-grid Photovoltaic Systems

Balkan Journal of Electrical and Computer Engineering, 2019
Submodule level maximum power point tracking (MPPT) systems have become popular due to its outstanding performance in partial shading conditions (PSCs) and basic algorithm requirement. MPPT is realized by DC-DC converters. They are power processing units

Improved power loss balance control for modular multilevel converters based on variable capacitor voltage deviation predefined value under SM malfunction

International Journal of Electrical Power & Energy Systems
When it concerns the reliable working of the modular multilevel converter (MMC), the power loss balance control cannot be ignored. Under the submodule (SM) malfunction condition, each arm of the MMC operates in an asymmetrical status, resulting in ...

New small, S-essential and S-small soft submodules

Gulf Journal of Mathematics
In this paper, we define a new version of small soft submodules by using the operation sums that were introduced by Turkmen and Pancar. Moreover, we introduce the concepts of S-small soft submodules and S-essential soft submodules. Moreover, we investigate their properties by focusing on mapping of each soft module.

Staircase Matrix Modulation for the Switched-Capacitor Modular Multilevel Converter With Sensor-Less Capacitor Voltage Balancing

IEEE Open Journal of Power Electronics
Staircase modulation is a switching technique ubiquitous in multilevel inverters utilizing large number of output voltage levels. With tens of levels, the output of a multilevel inverter employing staircase modulation approaches a sinusoid without ...
