This paper presents the results of studies on the influence of oxygen partial pressure (vacuum level in the chamber) on the properties of FeAl intermetallics. One of the problems in the application of classical methods of prepared Fe-Al intermetallic is the occurrence of oxides. Applying a vacuum during sintering should reduce this effect. In order to analyze the effect of oxygen partial pressu...

The paper describes the performance analysis, structural design and fabrication of piezoresistive pressure sensor using simulation technique. A polysilicon double nano-wire piezoresistor was fabricated by means of RIE (reactive ion etching). The polysilicon double nanowire pressure sensor has 100x100nm cross section area and has a thickness about 10nm. Finite element method (FEM) is adopted to ...

Consideration of the environmental, commercial and legal constraints on a practical home vacuumcleaning robot suggests that the best configuration is a compact single-purpose vehicle designed to map and follow a deliberate path. This configuration, suitably equipped with the necessary external and internal sensors, serves to define the AI requirements for mapping, path following, contingency ha...
