Multiphase PWM characteristics in the EER transmitter envelope path
2021 International Conference on Engineering Management of Communication and Technology (EMCTECH), 2021To create efficient telecommunication systems we need efficient telecommunication devices. The most energy-consuming element of any radio transmitting equipment is the radio frequency (RF) power amplifier (PA).

Store and Visualize EER in Neo4j
Proceedings of the 2nd International Symposium on Computer Science and Intelligent Control, 2018NoSQL databases have become very popular in the last few years. Graph databases, as a major NoSQL database type, are used for many problems. In relational databases, conceptual modeling is very important, for which Enhanced Entity-Relationship (EER ...

L’EER sert a « remplacer » la fonction renale lorsque cette derniere ne permet plus le maintien de l’homeostasie. L’objectif est de retirer les substances toxiques accumulees dans le sang (potassium, uree, creatinine, phosphore…), d’apporter du bicarbonate pour corriger l’acidose et de controler la balance hydrosodee.

As mentioned in Chapter 2, the enhanced entity-relationship (EER) model has largely enriched the usefulness and expressiveness of the ER model by introducing the concepts such as subclass and superclass, generalization and specialization, shared subclass and category, attribute inheritance, etc., as conceptual model constructs (Dos Santos, et al., 1979;
