Security design for a system takes on the personality of the design team. Unfortunately these design teams are often focused within a single engineering discipline, for instance the design team is ...either composed of mainly software engineers or hardware engineers. The systemic problem is that not only is the design team single discipline focused but they are also normally single discipline trained and educated. Most design engineers have a degree with a single emphasis, such as a software engineer, mechanical engineer, electrical engineer, etc. The engineers are not usually trained in-depth in all areas of software, electrical/electronic, chemical, and mechanical engineering, especially as these areas pertain to security and secure processing systems. A multiple disciplined team with a more systems engineering approach is proposed as a near-term solution to this problem, but the proposed long-term solution is a Bachelor/Masters combination degree program with significant advanced course work in multiple engineering discipline areas. Broader education and engineering training in multiple disciplines would further aid a multi-discipline team resulting in more comprehensive security design. This paper describes the types of protection mechanisms individual disciplines offer, describes the added protection robustness achieved as a result of using multiple disciplines, and describes the types of discipline education necessary for a more complete Security Engineering degree. PUBLICATION ABSTRACT
In this study, a search for neutron-antineutron ($n-\bar{n}$) oscillation was undertaken in Super-Kamiokande using the 1489 live-day or 2.45×1034 neutron-year exposure data. This process violates ...both baryon and baryon minus lepton numbers by an absolute value of two units and is predicted by a large class of hypothetical models where the seesaw mechanism is incorporated to explain the observed tiny neutrino masses and the matter-antimatter asymmetry in the Universe. No evidence for $n-\bar{n}$ oscillation was found, the lower limit of the lifetime for neutrons bound in 16O, in an analysis that included all of the significant sources of experimental uncertainties, was determined to be 1.9×1032 years at the 90% confidence level. The corresponding lower limit for the oscillation time of free neutrons was calculated to be 2.7×108 s using a theoretical value of the nuclear suppression factor of 0.517 × 1023 s-1 and its uncertainty.
A search for neutron-antineutron (n - n) oscillation was undertaken in Super-Kamiokande using the 1489 live-day or 2.45 x 10 super(34) neutron-year exposure data. This process violates both baryon ...and baryon minus lepton numbers by an absolute value of two units and is predicted by a large class of hypothetical models where the seesaw mechanism is incorporated to explain the observed tiny neutrino masses and the matter-antimatter asymmetry in the Universe. No evidence for n - n oscillation was found; the lower limit of the lifetime for neutrons bound in super(16)O, in an analysis that included all of the significant sources of experimental uncertainties, was determined to be 1.9 x 10 super(32) years at the 90% confidence level. The corresponding lower limit for the oscillation time of free neutrons was calculated to be 2.7 x 10 super(8) s using a theoretical value of the nuclear suppression factor of 0.517 x 10 super(23) s super(-1) and its uncertainty.
From a study of the kinematic properties of the final state produced in the semileptonic decays b-->X l nu, the inclusive charmless semileptonic branching ratio of b hadrons is measured. With a sam ...ple of 3.6 million hadronic Z decays recorded between 1992 and 1995 with the ALEPH detector at LEP, the value Br(b-->X_u l nu) is determined to be (1.73 +- 0.55_stat +- 0.55_syst)*10^{-3}, where X_u represents any charmless hadronic state and b is a mixture of b hadrons weighted by their production rates. This measurement yields the result |V_ub|^2= (18.68 +- 5.94_stat +- 5.94_syst +- 1 .45_HQE)*10^{-6}, where the last error comes from the conversion of the branching ratio to the CKM matrix element squared.
A search for neutron-antineutron (\(n-\bar{n}\)) oscillation was undertaken in Super-Kamiokande using the 1489 live-day or \(2.45 \times 10^{34}\) neutron-year exposure data. This process violates ...both baryon and baryon minus lepton numbers by an absolute value of two units and is predicted by a large class of hypothetical models where the seesaw mechanism is incorporated to explain the observed tiny neutrino masses and the matter-antimatter asymmetry in the Universe. No evidence for \(n-\bar{n}\) oscillation was found, the lower limit of the lifetime for neutrons bound in \({}^{16}\)O, in an analysis that included all of the significant sources of experimental uncertainties, was determined to be \(1.9 \times 10^{32}\)~years at the 90\% confidence level. The corresponding lower limit for the oscillation time of free neutrons was calculated to be \(2.7 \times 10^8\)~s using a theoretical value of the nuclear suppression factor of \(0.517 \times 10^{23}\)~s\(^{-1}\) and its uncertainty.
