This study explores the mechanical and optical properties of nanoporous copper (NPC) films dealloyed in acid and base using qualitative and quantitative measurements. Two types of NPC films (NPC 1 and NPC 2) were prepared by dealloying precursor films in different corrosive solutions. The films were characterized using atomic force microscopy (AFM)...

Second Harmonic Generation Microscopy (SHG) is widely acknowledged as a valuable non-linear optical imaging tool, its contrast mechanism providing the premises to non-invasively identify, characterize, and monitor changes in the collagen architecture of tissues. However, the interpretation of SHG data can pose difficulties even for experts histopat...

Email classification systems are essential for handling and organizing the massive flow of communication, especially in a business context. Although many solutions exist, the lack of standardized classification categories limits their applicability. Furthermore, the lack of Romanian language business-oriented public datasets makes the development o...

Air quality is a very hot topic now. Real-time monitoring through IoT technologies and cloud services allows each of us to check the outdoor air quality in various areas of the cities where we live at any time. A less discussed aspect is the fact that we spend only 20% of our time outside and the rest indoors, in our apartment, at work, or in other...

Chromium nitride thin films are known for their good mechanical properties. We present the characteristics of ultrathin chromium nitride films under 400 nm thickness deposited on silicon substrates by direct current and high-power impulse magnetron sputtering techniques. The methods of investigation of the CrN films were scanning electron microscop...

When the cornea becomes hydrated above its physiologic level it begins to significantly scatter light, loosing transparency and thus impairing eyesight. This condition, known as corneal edema, can be associated with different causes, such as corneal scarring, corneal infection, corneal inflammation, and others, making it difficult to diagnose and q...

Shipping is one of the major pressures that have a negative impact on conservation efforts in protected wetlands in Romania. Based mainly on the use of fossil fuels, shipping activities contribute significantly to water and air pollution. Reducing the carbon footprint by implementing ammonia and hydrogen on board has gained increasing interest in r...

In this study, different types of waste from poultry farms were analyzed in order to gasify them to obtain a synthesis gas that could be used in a gas turbine plant (ITG). In order to reduce the CO2 emissions generated by the whole process, the configuration of the chemical absorption process integration within the energy system was analyzed, namel...

The spread of Acinetobacter baumannii in clinical settings is a great concern at the time being, given the epidemic potential and the capacity to elude the effects of drugs of this bacterial species. How A. baumannii achieves its resistance determinants is not yet exactly understood, hence the need for new studies aimed at resolving its structu...

This paper shares the author's approach and experience in conducting a new laboratory for bioengineering undergraduates, suitable for remote working (supervising and students’ activity), imposed by the pandemic. The laboratory was conceived as project-oriented, with the intent of offering the students a practical engineering approach, focused on so...

Nowadays, every researcher and postgraduate student is faced with the problem of information overflow in his daily endeavours. Concurrently, it becomes more and more difficult for someone interested in certain topics to find the relevant and trending articles and authors from a field, and to visualize the underlying connections within a domain. Thi...

This paper presents the hardware and software structures of a proposed data acquisition and processing system, which is designated to perform an automated inspection of roads pavement condition. The system was designed to gather information from multiple sources - laser-based imaging systems for road profiling, cameras for environmental images, pro...

NOVELTY - The invention relates to a modular system as an autonomous container meant for refugee camps and for other insular installations and to a method for using the modular system. According to the invention, the modular system comprises a power subsystem (1), a communication subsystem (9) which takes over internal and external voice and data c...

The virtual reality technologies can be included into the e-learning system, according to specialized studies. At present education system is in a period of transition from traditional to digital and virtual. Out of the benefits of using the 3D technologies in education, we name: 3D virtual learning solutions involving students in the learning proc...

Introducing the e-learning platform for learning, assessment and continuous medical training in dental prosthetics is a complementary instrument meant to improve the educational process. The E-learning offers efective access to information, new methods for training, learning and knowledge assessment, professional training and represents an alternat...

Urgent need for energy savings involves introduction of intelligent monitoring and control networks for industrial consumers, including small and medium ones. New functions of smart grid and energy storage quality monitoring systems make up the path for new consumption ways. This paper presents a system solution that optimizes electricity consumpti...

The objective of the present scientific research was to develop a bio-monitoring platform for the supervision of personnel working in the critical infrastructure tested in a laboratory based on virtual reality simulations. The role of this platform is to collect a set of signals in order to determine the optimal physiological profile of personnel d...

This paper describes a system for power supply, monitoring, control and communication for isolated temporary habitats. The system described consists in six modules and offers all the necessary equipment in order to operate a fully functional camp.

In this paper is proposed a brain-computer interface. In order to develop and implement this interface, the programming environment LabVIEW was used. In order to recognize a K complex in the EEG signal, a simple detector was created, using Peak Detector VI in LabVIEW. The detector receives the representation of the power spectrum of the signal and...
