One of the methods for making prototypes is incremental forming process. In this method, the forming tool, performs a pre-programmed movement by the CNC machine and runs the desired path. This modernization process is used in the automotive, aerospace, military, medical and other industries. One of the most influential parameters in this process is forming tool. This parameter is effective in f...

Sheet metal forming is one of the most popular technologies for obtaining finished products in automotive industries. The main techniques sheet forming: microforming, warm/hot forming, incremental flexible-die Electromagnetic Electrohydraulic Spinning and Shear Spinning, Flow Forming cold forming. One stamping process. In production line Ravne VPS400 1992, we take twenty details looking quality...

In this paper we present an algorithm for inverse optimization problems concerning electromagnetic casting of molten metals. We are interested in locating suitable inductors around the molten metal so that the equilibrium shape be as near as possible to a desired target shape. A Simultaneous Analysis and Design (SAND) mathematical programming formulation is stated for the inverse problem. The r...

BACKGROUND The aim of this study was to evaluate and compare microwave disinfection with chemical disinfection of dental gypsum casts. MATERIALS AND METHODS A total of 120 casts were prepared from a silicone mold using Type III dental stone. Of the 120 casts, 60 casts were contaminated with 1 ml suspension of Staphylococcus aureus and 60 casts were contaminated with 1 ml suspension of Pseudom...

A new biosensor platform for the detection of bacterial pathogens based on long-range surface plasmon-enhanced fluorescence spectroscopy (LRSP-FS) is presented. The resonant excitation of LRSP modes provides an enhanced intensity of the electromagnetic field, which is directly translated to an increased strength of fluorescence signal measured upon the capture of target analyte at the sensor su...

introduction : the  rapid development  of wireless telecommunication technologies  over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fi elds. nowadays, people are continuously exposed to different sources of electromagnetic fi elds such as mobile phones, mobile base stations, cordless phones, wi-fi routers, and power lines. therefore,...

The present work aims to validate the application of accelerating thawing process (microwave oven 20 kW/60 seconds) for poultry meat chicken. Hence, several criteria, such as microbiological, organoleptic, nutritional, thawing time and cost, were evaluated by accelerated and slow processes (48 h during 4°C, reference method). After 5 weeks, and according to the microbiological criteria the resu...
