It was virtually declared that measurement science must abandon the error analysis of measurement when ISO had published "Guide to Expression of uncertainty in Measurement" International inclination of measurement field in order to guarantee the traceability and confidence of measurement results discards the error concept and instead analyzes the measurement uncertainty. In this paper we establish a mathematical model of measurement and analyze all uncertainty factors as possible as for yielding the measurement uncertainty in the course of the calibration of RF multimeter using Transfer Standard, Thermal Voltage Converter We produce the expanded uncertainty by analyzing cable effects, correlation of thermocoupler and DC meter, DC source, RF source, attenuator, reflection coefficients and DUT.s and DUT.

Specular reflection appears with metals, plastics, glasses and many other solid objects which are required to be inspected, assembled, moved, or processed automatically. Recongnizing such shiny objects with specular reflections is a hard problem for computer vision, since specular reflections appear, disappear, or change their shapes abruptly, due to tiny movements of the view. Traditionally, such specular reflections are discarded as annoying noise for recongnition purposes. In this paper a technique is represented for obtaining shapes of specular objects. The ring illumin- ation system employes a ring source which is positioned on the axis of the camera. The concept of the proposed method is that if specular objects are illuminated by the ring they show their own dis- tinctive specularity features in surface from which we can infer the shape of the object. A series of experiments are performed to evaluate the performance of this system.

Most of the studies based on the outcome of business ethics were mainly focused on financial and non-financial results, CEO's business ethics and practical willingness as a preceding variable for business ethics and its success. This study regards business innovation on corporate sustainability and social responsibilities. There fore, this study will prove the result of activities based on business innovation and its activities, for participation of members is of importance. Therefore, this study proved the hypothesis that a worker's ethical conciousness is important in the result of business ethics, and that it also effects the result of business ethics for practice and innovative intentions for a moderating effect. This study emphasizes on ethical consciousness related to business ethics and consensus related to business ethics due to members' ethical consciousness influenced by organization's business ethics and perception. There ought to be an implication for this study. Also, as a result variable, the job satisfaction of coworkers is affected by conscious business ethics, but not affected in the innovative intentions. In addition, it is shown that the consciousness of business ethics is a controllable variable, for it affects job satisfaction concerning coworkers, but does not affect general job satisfactions.
