An Analysis of the Computer and Network Attack Taxonomy

The Air Force\u27s dependence on the Internet continues to increase daily. However, this increased dependence comes with risks. The popularity and potential of the Internet attracts users with illegal as well as legal intentions. Since the Air Force considers the Internet an integral component of its information Operations strategy, the Air Force must be confident that it can trust the security of this component. Therefore, reliable methods and information that helps the Air Force classify the risks associated with the Internet can help the Air Force determine the best processes to assure the security of its use of this resource. This thesis examines the computer and network attack taxonomy developed by John Howard. The taxonomy is a possible method that the Air Force can use to help it classify Internet security attacks and incidents. This researcher concluded that the computer and network attack taxonomies were satisfactory. The questionnaire respondents appeared to prefer the 1998 version more. This researcher also concluded that organizations responsible for the collection and distribution of Internet Security information, do explicitly collect some, not all, information useful as input into the taxonomy

A COMPARATIVE ANALYSIS OF COMMUNITY WATER SYSTEMS AND DRINKING WATER ADVISORIES ACTIVE IN SASKATCHEWAN COMMUNITIES FROM 2012-2016

This research aimed to describe temporal patterns in the number and duration of drinking water advisories in Saskatchewan communities on and off reserve from 2012 to 2016. The analyses included 445 communities – including cities, towns, villages, and reserves – in which 2036 advisories were in effect. The large sample test of proportion was used to compare the observed proportion of advisories issued which occurred on and off reserve to the expected proportion based upon the proportion of communities which experienced an advisory during the study period that were reserve or non-reserve. Comparisons were also conducted which took into account the size of non-reserve communities, the season advisories were issued, the year advisory were issued, and the community’s geographic region. Descriptive statistics were utilized to describe reasons for issuing advisories. The duration of advisories was investigated using the same comparisons, as well as the reason for issuing advisories, using the Kruskal Wallis and Mann Whitney U Test. Reserve drinking water systems were found to have fewer advisories than would be expected when compared to communities off reserve (p<0.01). Advisories on reserve were longer lasting than those off reserve, the median advisory lasted 14 days on reserve and 9 days for the smallest community type off reserve (villages) (p<0.01). Advisories occurred more often in summer for both reserve and non reserve communities. But while advisories were equivalent in duration across seasons off reserve, advisories issued for reserves were significantly longer if they were issued during the winter(p=<0.02). Advisories were issued more often off reserve for depressurization and equipment issues, while power outages, disinfection failures, contamination, and operation deviation were more common on reserve. The analyses included in this study highlight the acute problem of drinking water on reserve and shows that significant work remains to ensure that all Saskatchewan residents have access to safe, potable drinking water. The use of comparison between reserve and non-reserve communities represents an important step forward towards understanding the extent and causes of drinking water disparities across Saskatchewan

Transcutaneous measurement of volume blood flow

Blood flow velocity measurements, using Doppler velocimeter, are described. The ability to measure blood velocity using ultrasound is derived from the Doppler effect; the change in frequency which occurs when sound is reflected or transmitted from a moving target. When ultrasound of the appropriate frequency is transmitted through a moving blood stream, the blood cells act as point scatterers of ultrasonic energy. If this scattered ultrasonic energy is detected, it is found to be shifted in frequency according to the velocity of the blood cells, nu, the frequency of the incident sound, f sub o, the speed of sound in the medium, c, and the angle between the sound beam and the velocity vector, o. The relation describing this effect is known as the Doppler equation. Delta f = 2 f sub o x nu x cos alpha/c. The theoretical and experimental methods are evaluated

An Evolutionary Sequence of Expanding Hydrogen Shells in Galaxy Discs

Large HI shells, with diameters of hundreds of pc and expansion velocities of 10-20kms-1 are well observed features of local gas rich galaxies. These shells could well be predicted as a result of the impact of OB associations on the ISM, but doubt has been cast on this scenario by the apparent absence of OB stars close to the centres of a large fraction of these shells in recent observations of the SMC. Using Fabry-Perot scanned Halpha emission line mapping of nearby galaxy discs we have detected, in all the HII regions where the observations yield sufficient angular resolution and S:N ratio, dominant Halpha shells with radii a few tens of pc, expanding at velocities of 50-100kms-1. We have applied a simple dynamically consistent framework in which we can extrapolate the properties of the observed Halpha shells to a few 10^7yr after the formation of the OB stars. The framework includes the dynamical inputs of both winds and SNe on the surrounding ISM. The results give quantitative statistical support to the hypothesis that the Halpha emitting shells are generic progenitors of the HI shells. During the time taken for an expanding shell to reach the size of a typical HI shell, the OB association may well lose its most luminous stars so the absence of such stars near the centres of many of the HI shells is well explained in this scenario.Comment: 8 pages, 4 figures, accepted for publication in Astronomy and Astrophysic

Experimental evidence of a natural parity state in 26^{26}Mg and its impact to the production of neutrons for the s process

We have studied natural parity states in $^{26}$Mg via the $^{22}$Ne($^{6}$Li,d)$^{26}$Mg reaction. Our method significantly improves the energy resolution of previous experiments and, as a result, we report the observation of a natural parity state in $^{26}$Mg. Possible spin-parity assignments are suggested on the basis of published $\gamma$-ray decay experiments. The stellar rate of the $^{22}$Ne($\alpha$,$\gamma$)$^{26}$Mg reaction is reduced and may give rise to an increase in the production of s-process neutrons via the $^{22}$Ne($\alpha$,n)$^{25}$Mg reaction.Comment: Published in PR

Management of indigenous North American deer at the end of the 20th century in relation to large predators and primary production

Five deer species occupy North America: caribou (3.6 × 106individuals), moose (1.1 × 106), white-tailed deer (28.5 × 106), mule deer (5.0 × 106) and wapiti (1.1 × 106). Caribou characterise the north of the boreal forest and the tundra, whereas moose dominate in coniferous and mixed forests growing further south. White-tailed deer are typical of the deciduous forests of the east while mule deer replace them in the mountainous terrain of the west. Wapiti possess the smallest range, mostly adjacent to the prairies to the west. The two large obligate carnivores preying on deer show a reduced distribution: wolves are almost restricted to Canada, and cougar to the mule deer range. We determined the current status of each species with the help of a questionnaire mailed to all jurisdictions harbouring deer. Most reports of threatened populations concerned caribou whereas many jurisdictions declared overabundance of white-tailed deer and wapiti. Hunting was allowed for all species when they abounded in a jurisdiction. Hunters harvested annually 7.0 × 106deer on the continent, 87% being white-tailed deer. The two species that caused most conflicts with humans had the highest harvest rate: 16-17%. In terms of biomass, white-tailed deer and wapiti yielded the highest harvests, with 55 and 39 kg × km-2of range, respectively. The average standing biomass of deer in winter ranged between 28 kg × km-2in Nevada to 901 kg × km-2in Indiana. The lowest standing biomasses occurred in the boreal forest (predators), in the prairies (agriculture) and in the south-west (aridity), and the highest ones in the south-east, where only white-tailed deer is present. The current abundance of deer in North America parallels, in general, the primary production of the landscape (r2= 0.38; P < 0.0001), but predators and human activity modify this pattern

H-alpha Kinematics of the SINGS Nearby Galaxies Survey. I

This is the first part of an Halpha kinematics follow-up survey of the SINGS sample. The data for 28 galaxies are presented. The observations were done on three different telescopes with FaNTOmM, an integral field photon counting spectrometer, installed in the respective focal reducer of each telescope. The data reduction was done through a newly built pipeline with the aim of producing the most homogenous data set possible. Adaptive spatial binning was applied to the data cubes in order to get a constant signal-to-noise ratio across the field of view. Radial velocity and monochromatic maps were generated using a new algorithm and the kinematical parameters were derived using tilted-ring models.Comment: 47 pages, 37 figures, accepted for publication in MNRAS.
