Normalized Efficiency for Stagewise Operations
(Amer Chemical Soc, Washington, 2011)
Tray efficiency in gas-liquid operations is a widely discussed theme, and the shortcomings of Murphree's, Hausen's, Standart's, and Holland's efficiencies are well-known. The new parameter "normalized efficiency" is defined ...
On the instability of steady motion
(Springer, Dordrecht, 2011)
This paper deals with the instability of steady motions of conservative mechanical systems with cyclic coordinates. The following are applied: Kozlov's generalization of the first Lyapunov's method, as well as Rout's method ...
Analysis of welded tensile plates with a surface notch in the weld metal and heat affected zone
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The behavior of the plates with a surface notch under tensile external loading is experimentally and numerically analyzed. The specimens were made of micro-alloyed steel NIO-MOL 490 K. welded by MAC (CO2) welding method. ...
An intelligent approach to robust multi-response process design
(Taylor & Francis Ltd, Abingdon, 2011)
In order to meet strict customer demands in a global highly-complex industrial sector, it is necessary to design manufacturing processes based on a clear understanding of the customer's requirements and usage of a product, ...
On the brachistochrone of a variable mass particle in general force fields
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The problem of the brachistochronic motion of a variable mass particle is considered. The particle moves through a resistant medium in the field of arbitrary active forces. Beginning from these general assumptions, and ...
Load-bearing steel structure diagnostics on bucket wheel excavator, for the purpose of failure prevention
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The appearance of cracks on load-bearing steel structure of compact, hydraulic bucket wheel excavator was a perennial problem. Unfavourable stress concentration, inadequate geometry and structure of materials, inadequate ...
Analysis of the stress state of multilayer pressed joints
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
This paper presents the results of analytical, numerical and experimental research of the stress-strain states of multilayer pressed joints in the field of elastic deformations. Suitable numerical (FEM) and analytical ...
Prediction of brake friction materials recovery performance using artificial neural networks
(Elsevier Sci Ltd, Oxford, 2010)
The brake friction materials in an automotive brake system are considered as one of the key components for overall braking performance of a vehicle. The sensitivity of friction material performance and accordingly brake ...
Abstract metric spaces and Hardy-Rogers-type theorems
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The purpose of the present paper is to establish coincidence point theorem for two mappings and fixed point theorem for one mapping in abstract metric space which satisfy contractive conditions of Hardy-Rogers type. Our ...
Structure and enhanced antimicrobial activity of mechanically activated nano TiO2
(Wiley, Hoboken, 2019)
Titanium dioxide is a photocatalyst, known not only for its ability to oxidize organic contaminants, but also for its antimicrobial properties. In this article, significant enhancement of the antimicrobial activity of TiO2 ...
