Inspection and quality control of casting in the Ajaokuta steel company’s foundry shop

The inspection of casting has dual purpose of ensuring that the product confirms to design requirements and of providing information needed for quality control in Foundry. This paper therefore clearly looked into the two components with a view to understanding important of inspection and quality control of production processes with a view to achieving quality castings which adherence to quality control principles. The study further discuss the  importance of  using computer for inspection and quality control analysis which has become necessary particularly as regarding the prediction of solidification patterns of casting and several alternative casting methods  that can be simulated before the final method is chosen.&nbsp

CMS Physics Technical Design Report: Addendum on High Density QCD with Heavy Ions

This report presents the capabilities of the CMS experiment to explore the rich heavy-ion physics programme offered by the CERN Large Hadron Collider (LHC). The collisions of lead nuclei at energies $\sqrt{s_{NN}}= 5.5\,{\rm TeV}$ , will probe quark and gluon matter at unprecedented values of energy density. The prime goal of this research is to study the fundamental theory of the strong interaction \u2014 Quantum Chromodynamics (QCD) \u2014 in extreme conditions of temperature, density and parton momentum fraction (low- x ). This report covers in detail the potential of CMS to carry out a series of representative Pb-Pb measurements. These include "bulk" observables, (charged hadron multiplicity, low p T inclusive hadron identified spectra and elliptic flow) which provide information on the collective properties of the system, as well as perturbative probes such as quarkonia, heavy-quarks, jets and high p T hadrons which yield "tomographic" information of the hottest and densest phases of the reaction
