an extended octagonal ring (eor) transducer was designed and developed to measure forces inside the compression chamber of a large square baler in different directions. the transducer was calibrated by applying forces in three directions simultaneously and independently. the sensor revealed excellent linearity along with small cross sensitivities. horizontal and vertical primary sensitivities o...

soil compaction and moisture content are two of the factors that greatly influence variations in crop yield. capacitance-based sensor is a sensitive device for estimating soil water content. in this method of soil moisture content measurement, soil acts as the dielectric of the capacitor. throughout this research work, a capacitance-based moisture sensor that can measure the soil moisture conte...

wireless sensor networks are composed of hundreds or thousands of small nodes called sensor that work together and are associated with a specific task or tasks to do. each of these nodes includes sensor, processor, communication components, a small memory and a source of energy. it is expected that wireless sensor networks will be used widely in many applications in near future. scalability and...

In vanadium-doped CsCl crystals grown from aqueous solutions anisotropic EPR spectra due to V0 are observed and analyzed at room temperature. Evidence is presented that isotropic spectra of this ion observed in this and other compounds are due to inclusions of growth solution and not to rapid rotation of the vanadyl ion in the solid as normally assumed. At 77 K a well resolved vibrational progr...

The title compound, [V(C(16)H(14)N(2)O(2))O], was synthesized by the reaction of vanadyl(IV) sulfate and N,N'-bis-(salicyl-idene)ethyl-enediamine under hydro-thermal conditions. The asymmetric unit contains two mol-ecules. Each V(IV) atom is coordinated in a square-pyramidal geometry by two N atoms and two O atoms from a ligand in the basal plane and by an oxide O atom in the apical position. W...
