Process Check of Annealing Process of Coiled Sheets by Indirect Measurement
K. Kostúr, TU Košice, BERG Faculty, Košice, Slovakia The contribution deals with a possibility of increasing quality production and decreasing costs in annealing furnaces by process check of annealing temperatures. The lowest temperature of annealed coiled sheets is very important. The information about this inner temperature is unknown during annealing. It is possible to obtain this informatio...
متن کاملMeasurement of avian embryo respiration by an indirect calorimetric system
Hamidu, J.A., J.J.R. Feddes, C.A. Ouellette and G.M. Fasenko. 2010. Measurement of avian embryo respiration by an indirect calorimetric system. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada. 52: 4.9 4.14. Accurate measurement of embryonic respiration can be used to determine the viability of the chicken embryo and the chick upon hatching. This measurement is based on both t...
متن کاملEntanglement and Nonunitary Evolution
We consider a collapsing relativistic spherical shell for a free quantum field. Once the center of the wavefunction of the shell passes a certain radius rs, the degrees of freedom inside rs are traced over. We show that an observer outside this region will determine that the evolution of the system is nonunitary. We argue that this phenomenon is generic to entangled systems, and discuss a possi...
متن کاملNonunitary quantum circuit
A quantum circuit is generalized to a nonunitary one whose constituents are nonunitary gates operated by quantum measurement. It is shown that a specific type of one-qubit nonunitary gates, the controlled-not gate, as well as all one-qubit unitary gates constitute a universal set of gates for the nonunitary quantum circuit, without the necessity of introducing ancilla qubits. A reversing measur...
متن کاملNonunitary Quantum Theory with a Field Cutoff
We consider a scalar quantum field theory, in which the interaction takes the form of a field cutoff; the energy diverges to infinity whenever the value of the field at some point falls outside a finite interval. In a simple (1+1)-dimensional version of this theory, we may calculate the results of certain scattering processes exactly. The main feature of the nontrivial solutions is the appearan...
