We introduce a technique for forcing the calibration of a financial model to produce valid parameters. The technique is based on learning from hints. It converts simple curve fitting into genuine calibration, where broad conclusions can be inferred from parameter values. The technique augments the error function of curve fitting with consistency hint error functions based on the Kullback-Leible...

volume in each test tube was adjusted to 10 ml with distilled water. The absorbance of the solutions was measured at 253 nm against distilled water as a blank and calibration curve was constructed. Similarly absorbance of sample solution was measured and amount of acyclovir was determined by referring to the calibration curve. Recovery studies were carried out by adding a known quantity of pure...

background: nitrogen oxides occur in the atmosphere in six forms of namely: n2o , no , no2 , n2o3, n2o4 and n2o5 .among these oxides no2 is the most important air pollutant because of its relatively high toxicity and its ubiquity in ambient air. in this research griess-saltzman method was utilized for determination of nitric oxide and nitrogen dioxide in the atmosphere of different laboratories...

We present a new method of rapidly determining the local critical current density (Jc) in large superconducting pellets without destroying the sample. We show that magnetoscan data averaged over a certain small sample area can be mapped directly onto absolute values of Jc. This conclusion and the corresponding calibration curve are based on results from magnetoscan and from SQUID measurements o...

Wittke et al. (1) present evidence of a major cosmic impact at the onset of the Younger Dryas (YD) episode, including some markers found in the top of the well-known Usselo marker horizon (UH). This finding is contrary to our extensive radiocarbon dating effort from this horizon (2), which shows that the UH at Aalsterhut postdates the onset of the YD. Furthermore, Wittke et al. (1) misinterpret...

* This work is supported by EU-IST-2001-34401 VAMPIRE. Abstract – Within a hybrid vision / inertial tracking system proper calibration of the sensors and their relative pose is essential. We present a new method for 3-axis inertial sensor calibration based on model fitting and a method to find the rotation between vision and inertial system based on rotation differences. We achieve a coordinate...
