Positioning systems that use location fingerprinting techniques are gaining popularity in recent years due to their cost effectiveness and accuracy as compared to other infrastructure based localization *** technique records the vectors of received signal strength from several mobile base stations in a database and later matches these to a new measurement to get the location of the *** analysis of received signal strength is essential for understanding and predicting the behavior of fingerprints under different physical *** analysis enables the designer to glean insights into location dependent features of location *** would facilitate the system designers in accurately modeling an efficient system with improved positioning *** this paper we present the analysis of the radio map of test area extracted from the GSM network with various metrics like time,orientation *** try to infer the relationships,dependencies among them.

The excitation function of the 58Ni(n,p)58Co reaction was measured using the well-established neutron activation technique andγ-ray *** in the energy range of 1.7 to 2.7 MeV were generated using the 7Li(p,n)*** neutron flux was measured using the standard 115In(n,n’)115mIn monitor *** results of the neutron spectrum averaged cross-section of 58Ni(n,p)58Co reactions were compared with existing cross-section data available in the EXFOR data library as well as with various evaluated data libraries such as ENDF/B-VIII.0,JEFF-3.3,JENDL-4.0,and *** calculations were performed using the nuclear reaction code *** nuclear level density(NLD)models were tested,and their results were compared with the present *** NLDs were also obtained through the spectral distribution method(SDM).The cross-section results,along with the absolute errors,were obtained by investigating the uncertainty propagation and using the covariance *** forγ-ray true coincidence summing,low-energy background neutrons,andγ-ray self attenuation were *** experimental cross-section obtained in the present study is consistent with previously published experimental data,evaluated libraries,and theoretical calculations carried out using the TALYS code.
