Sequential quantum cloning.
Not all unitary operations upon a set of qubits can be implemented by sequential interactions between each qubit and an ancillary system. We analyze the specific case of sequential quantum cloning, 1-->M, and prove that the minimal dimension D of the ancilla grows linearly with the number of clones M. In particular, we obtain D=2M for symmetric universal quantum cloning and D=M+1 for symmetric ...
متن کاملAutomated evaluation of ANA under real-life conditions
INTRODUCTION Visual evaluation of indirect immunofluorescence (IIF) on human epithelial-2 cells is the routine method for screening for antinuclear antibodies (ANA) in connective tissue diseases. Since visual IIF is time-consuming and subjective, automated IIF processors have been developed to offer standardised, valid and cost-efficient IIF assays. OBJECTIVE The aim of this study was to dete...
متن کاملA Nurse Scheduling Model under Real Life Constraints
Background and Objectives: In this paper, a real life nurse scheduling model is described based on the conditions in Iranian hospitals such as monthly shift rotation, consecutive morning and evening shifts and consecutive evening and night shift. Methods: The developed model considers both hospital constraints and nurses’ preferences. Hospital constraints include assigning adequate qualifie...
متن کاملReal Time Face Recognition under Different Conditions
Face recognition is an active area of research since 1980s. It is one of the most successful and important applications of image analysis and processing. Eigenface approach is one of the earliest appearance-based face recognition methods, which was developed by M. Turk and A. Pentland in 1991 [1]. This method utilizes the idea of the Principal Component Analysis (PCA) which decomposes a face im...
متن کاملFace Recognition under Real-world Conditions
This paper deals with Automatic Face Recognition (AFR). The main contribution of this work consists in the evaluation of our two previously proposed AFR methods in real conditions. At first, we compare and evaluate the recognition accuracy of two AFR methods on well-controlled face database. Then we compare these results with the recognition accuracy on a real-world database of comparable size....
