  • Setting of the angle of incidence for generating Lamb waves by non-contact method 
    BUGA, Alexandru (Universitatea Tehnică a Moldovei, 2021)
    The article examined the problem of the experimental setting of incidence angles for the generation of Lamb waves in plate-type parts by the non-contact ultrasonic control method. This type of control is mainly done by the ...
  • Some particular aspects of the automotive industry connectors 
    BĂJENESCU, Titu-Marius I. (Technical University of Moldova, 2021)
    Electrical connectors are very sensitive parts in an electronic system. The actual meaning of reliability and the problems associated with determining it, are often not right understood. The paper presents some particular ...
  • Some reliability aspects of MEMS and NEMS manufacturing 
    BĂJENESCU, Titu-Marius I. (Technical University of Moldova, 2021)
    A full understanding of the physics and statistics of the defect generation is required to investigate the ultimate reliability limitations of manufacturability of MEMS and NEMS. In order that the user can include electronic ...
  • Spectral space as a method for data crypto protection using the Fast Fourier Transform 
    BALABANOV, Anatoly; KUNEV, Vyacheslav; COLESNIC, Victor (Technical University of Moldova, 2021)
    The article proposes to solve the problem of real-time application (on-line) of asymmetric bit-by-bit (flow or phoneme block, 32-, 64-,…, n-bits block) encryption of the linear and / or non-linear formants of the spectrum ...
  • Stages of formation of architecture of Chisinau administrative buildings 
    OLEINIC, Svetlana (Technical University of Moldova, 2021)
    This article reveals the stages of formation of the architecture of administrative buildings in the city of Chisinau on the background of historical and economic transformations, that took place in Moldova from the late ...
  • Stress - strain state of the local area in the building element with structural defect 
    KOLOKHOV, Victor; SAVYTSKYI, Mykola; SOPILNIAK, Artem (Technical University of Moldova, 2021)
    Evaluation of the building element technical state relies on verification calculations using estimated construction material properties. Physical and mechanical properties are estimated predominately by using non-destructive ...
  • Structural parameters of concrete corrosion resistance 
    ELETCHIH, Albina (Technical University of Moldova, 2021)
    This article describes the problem of corrosion of concrete at the enterprises of the wine and fruit and vegetable industry in Moldova, the kind of organic acids that destroy concrete are considered. Such a specific type ...
  • SWOT principle in flood risk management 
    GRAMA, Vasile; AVANZI, Agostino; NISTOR-LOPATENCO, Livia (Technical University of Moldova, 2021)
    An analysis of global statistics shows a substantial increase in flood damage over the past few decades. With the recent transition to a more risk-based approach in European flood management policy, flood analysis models ...
  • Target recognition based on central and logarithmic central image chord transformations 
    PERJU, Veaceslav (Technical University of Moldova, 2021)
    Object recognition is of great importance for many civil and military applications and supposes the identification and classification of the object in real-time, regardless of spatial position, angular orientation, etc. ...
  • TiO2 nanotubes for photocatalytic degradation of methylene blue 
    CIOBANU, Vladimir; PLESCO, Irina (Technical University of Moldova, 2021)

  • Total favoring in proportional apportionments 
    BOLUN, Ion (Technical University of Moldova, 2021)
    The notion of “total favoring” of large or of small beneficiaries in proportional apportionments of entities is defined as a particular case of favoring. It is proven that the number of known conditions of total favoring ...
  • Trust- based modeling MAC-type access control through access and actions control policies 
    DANILESCU, Marcel; BEŞLIU, Victor (Technical University of Moldova, 2021)
    In recent decades, the number of researches on access control and user actions in computer systems has increased. Over time, there have been two models of implementing Mandatory Access Control (MAC) policies for government ...
  • The use of geographic information system for flood predictions 
    TABACARU, Alexandru; NISTOR-LOPATENCO, Livia; BEJAN, Iurie; PANTAZ, Alexandru (Technical University of Moldova, 2021)
    The article examines the issue of using geographic information systems (GIS) and WEBGIS technologies to predict areas likely to be flooded. Probabilistic flood hazard maps (0.5%, 0.1% and 1% flood risks) were used, obtained ...
