This study presents a mud pumping equipment that can be attached to the excavator arm. This equipment can solve ecological issues in narrow spaces, in areas where access is limited as well as during floods. Tthe technological ...

The research presented in this scientific paper investigates an adaptive seismic isolation system meant to protect architectural monuments structures subjected to a variety of seismic ground motions. This scientific paper ...

Decisions on acceptance of order and production planning in the manufacturing system are often considered separately. Sales Department is responsible for accepting orders, while the production department deals with ...

In order to better represent the specified goal of the manufacturing process we propose (as a novelty) as a criterion the Earning Power (EP). It is both synthetic (because it reflects the essential motivation of the ...

The work in seismic design of bridges needs to develop physical models and mathematical theory, based on which will be assessed and quantified the dynamic response of bridge structures subjected to stress arising from ...

The article is taking into consideration a nonlinear model for the damping, where the damping coefficient has a polynomial variation function of the velocity. The differential equation of the movements of the non-linear 1DOF ...

This paper presents the thermoelectric generators which converting directly heat flow into electric energy. Thermoelectric modules (TEM) normally designed for cooling are suited for power generation as well, as they are ...

The article presents the problem of the testing of some protective systems made of PU foam based composite materials which can simultaneously meet the following requirements: noise absorption for middle and high range ...

The seismic protection of buildings has been a successful strategy for the past 30 years. Seismic protection systems ensure the safety of any type of building even under most severe earthquakes. Seismic devices not ...

The movements of many material systems can be described by differential equations that have coefficients that depend on time. It is difficult to determine the solutions of these equations. Although many concrete problems ...
