Full-text available
The bio-medical benefits of silver ions and 10-undecenoic acid in various chemical-pharmaceutical preparations are indisputable, thus justifying numerous research studies on delayed and/or controlled release. This paper presents the effect of the polymer matrix in the simultaneous release of silver ions and 10-undecenoic acid in an aqueous medium o...

Regardless of the type of liquid membrane (LM) (Bulk Liquid Membranes (BLM), Supported Liquid Membranes (SLM) or Emulsion Liquid Membranes (ELM)), transport and separation of chemical species are conditioned by the operational (OP) and constructive design parameters (DP) of the permeation module. In the present study, the pH of the aqueous source p...
Article
Full-text available
Liquid membranes usually have three main constructive variants: bulk liquid membranes (BLM), supported liquid membranes (SLM) and emulsion liquid membranes (ELM). Designing hybrid variants is very topical, with the main purpose of increasing the flow of substance through the membrane but also of improving the selectivity. This paper presents the op...

The recovery of osmium from residual osmium tetroxide (OsO4) is a necessity imposed by its high toxicity, but also by the technical-economic value of metallic osmium. An elegant and extremely useful method is the recovery of osmium as a membrane catalytic material, in the form of nanoparticles obtained on a polymeric support. The subject of the pre...

Composite membranes play a very important role in the separation, concentration, and purification processes, but especially in membrane reactors and membrane bioreactors. The development of composite membranes has gained momentum especially through the involvement of various nanoparticles, polymeric, oxide, or metal, that have contributed to increa...
Article
Full-text available
Membranes are associated with the efficient processes of separation, concentration and purification, but a very important aspect of them is the realization of a reaction process simultaneously with the separation process. From a practical point of view, chemical reactions have been introduced in most membrane systems: with on-liquid membranes, with...
Article
Full-text available
The membranes and membrane processes have succeeded in the transition from major technological and biomedical applications to domestic applications: water recycling in washing machines, recycling of used cooking oil, recovery of gasoline vapors in the pumping stations or enrichment of air with oxygen. In this paper, the neutralization of condensati...
Article
Full-text available
This paper describes the steps involved in obtaining a set of relevant data sources and the accompanying method using software-based sensors to detect anomalous behavior in modern smartphones based on machine-learning classifiers. Three classes of models are investigated for classification: logistic regressions, shallow neural nets, and support vec...
Chapter
The paper present IoT Open Architecture Ground Control System by adaptive fusion intelligent interfaces to the robot vectors communications applied to network densification in 5G Era. Intelligent interfaces for optimization and decision-making using neural networks, neutrosophic logic and deep learning convolutional are analyzed. The proposed solut...
Article
Full-text available
The paper presents the design and implementation of a fuzzy inference system (FIS) trained with adaptive neural networks for the generation of specification references in high frequency current (HFC) hardening processes. The specification references are then further used for the control of the process in obtaining the desired outcomes in terms of m...
Article
Full-text available
The article focused on the advanced intelligent control of the stability of anthropomorphic walking robots (AWRs), in order to validate a new and useful method of moving in the virtual environment, which determines a substantial increase in their stability. The obtained results lead to Versatile Intelligent Portable Robot Platform VIPRO, developed...
Article
Full-text available
Autonomous weather monitoring applications, especially the distributed ones, implies low power consumption both for sensors and computing/storage facilities. Making the autonomous system more efficient requires optimizing consumption for the computing and storage facilities are they require more energy to function than the sensors. Modern embedded...
Conference Paper
Full-text available
The paper presents the principles of a dynamic key encryption method based on cellular automaton type key generator. The reason of using a cellular automata model for this kind of application is mainly based on its high degree of parallelism and huge number of possible states. Cellular automata can be hardware implemented using hardware devices or...
