Elaboration of a computer system for determining the energy of laser pulse

This work investigates the neutron-induced fission of U-234 and the fission-fragment properties for neutron energies between E-n = 0.2 and 5.0 MeV with a special highlight on the prominent vibrational resonance at E-n = 0.77 MeV. Angular, energy, and mass distributions were determined based on the double-energy technique by means of a twin Frisch-grid ionization chamber. The experimental data are parametrized in terms of fission modes based on the multimodal random neck-rupture model. The main results are a verified strong angular anisotropy and fluctuations in the energy release as a function of incident-neutron energy

Study The Effect of Traditional Iraqi Stabilizers (Cement and Lime) on Some Properties of Iraqi Clay Soils

This study provides practical results in the use of the composite from sulfate resistance Portland cement (PC) and Quicklime (LQ) to improve and stabilize of soils in Al - Zaafaraniya site in Baghdad governorate and the Garma Ali site in Al Basra governorate, Iraq. PC and LQ were added in percentages of 2,4,6,8 and 10% and 2 and 4%, by dry weight, respectively. Laboratory tests to determine Atterberg,s limits, standard proctor test, USC test and UUU test (unconsolidation, undrained and unsaturated) were conducted. The results achieved a significant improvement in workability, unconfined compressive strength and shear strength. The results of the unconfinedicompressiveistrength test and UUU test for natural and improved soil reveal that the shear strength increase as lime and cement content increase and with increasing curing (0, 7 and 28)days

Comparison Between Deterministic and Stochastic Interpolation Methods for Predicting Ground Water Level in Baghdad

Surface interpolation techniques are usually used to create continuous data (i.e. raster data) from distributed set of point data over a geographical region. There are deterministic and stochastic (geostatistical) interpolation techniques can be used to create spatial raster surface. In this paper, the comparison between the Inverse Distance Weight (IDW) interpolation method as deterministic method and the Kriging interpolation method as stochastic method is done to determine the best performance for measuring levels of ground water in Baghdad Governorate. Spatial raster surface surfaces as ground water prediction maps are generated from each method by using average ground water level measured at 206 wells in the study area. These maps are shown spatial variation in the ground water levels and they have complete different. The IDW method results a refined map and lesser error than the Kriging method. Thus, the analysis shows that the IDW gives better real performance of measuring levels of ground water in Baghdad Governorate
