Abstract:

This thesis explores the Anglo-American supply relationship, 1939-1941, and the ability of these two nations to wage a coalition war immediately after the Japanese attack on Pearl Harbor. Organisationally, the first chapters of the thesis look at the impact of the Great War and the interwar period on this relationship. The remaining chapters are devoted to the evolution of the supply relationship between September 1939 and December 1941. The evidence found in British and American archives indicates that early supply discussions, conducted under the supervision of Arthur Purvis and Henry Morgenthau, established a common ground for Anglo-American co-operation during the early days of the Second World War. The fall of France prompted the British Government to seek much closer ties with the United States. However, in mid-1940 many senior US officials insisted that America should concentrate on its own defence against the Nazi threat because of the likelihood of Britain's defeat. By the end of 1940, the American defence planners were more confident of Britain's ability to survive, and therefore they were willing to consider the creation of Anglo-American defence plans. At the same time President Roosevelt requested Congressional approval for the Lend-Lease Act, to ensure the British Government could still acquire US war supplies even if it lacked the dollars to pay for them. Because of the inability of US industry to produce adequate war materiel for the British effort and American rearmament, representatives from the two countries were forced to work closely together to determine production and allocation priorities. Moreover, since these decisions influenced the fighting capability of British and American forces, war planners rather than civilians officials began to make these supply decisions. Subsequently, British and American officials determined that their efforts should be based on a joint strategy. Ultimately this realisation inspired the creation of the Victory Programme, which effectively acknowledged that supply needs, strategic considerations, and an overall commitment to defeat Germany and its allies were indistinguishable. Thus the supply relationship, 1939-1941, provided the foundation for the Anglo-American wartime coalition against Hitler.

Abstract:

The major objectives of this study were to examine electrical and electromechanical properties of SBR filled with carbon black in the 0-70 phr range. The experiments were divided into four parts: dielectric measurement, loss modulus and phase angle measurements, temperature rise measurement during stress cycling, and dynamic conductivity measurement. It is established that there are three distinct conduction regimes existing at carbon black loadings below, at, and above the percolation threshold. Characteristics of dielectric dispersion depend strongly on carbon black loading and frequency. Dielectric and AC conductivity measurements are shown to provide a nondestructive method to explore the carbon black network inside the rubber. Both loss modulus and phase angle are related to hysteresis properties, and to temperature rise due to compressive cycling. Measurements of these parameters will be discussed in detail, as functions of carbon black loading, stress and strain amplitudes, and oscillation frequency. These and other results can be understood in terms of the mechanics of the carbon black network. The variation of conductivity with strain amplitude is related directly to the interplay between the "persistent" and "transient" fractions of carbon black network. It is shown that, owing to its experimental accuracy and great sensitivity to carbon black network changes, the dynamic conductivity measurement is preferable to traditional modulus measurements for determining certain dynamic properties of carbon black filled rubbers.

Abstract:

After a U. S. Navy ship is built but before it is placed into service, many performance tests of all shipboard systems are conducted. These tests vary greatly in who performs the test, the purpose of each test, which system or systems are being tested, and the duration of each test. As naval warfare ships become increasingly complicated, the performance tests that are conducted also become numerous and complex. The current test philosophy prescribes that for each test and test organization, telemetry cables for electrical sensors are strung throughout the ship immediately prior to the test being conducted. As the shipboard tests and trials become more numerous and complex this philosophy becomes expensive from a labor and materials point of view.

This thesis proposes an economical solution to the current test and trials problem by offering a fiber optic network with optical sensors. The fiber optic network will be designed to accommodate as many different users as possible, and it will be installed once, during the new ship construction. Prior to the network design, optical fiber sensor schemes are discussed. One sensing scheme, using quartz crystal oscillators, looks promising for the test and trials application. This one sensing method can be applied to acceleration, velocity, displacement, temperature, current, and voltage. Thus economies can be realized by using one network and sensor type for the majority of tests and trials applications.

Full text

Abstract:

This thesis examined the 'recoil' effect of the ice hockey stick shaft during a stationary slap shot. Nine subjects were tested. Four were classified as 'elite' and the remaining five as the 'recreational' group. Their performances were evaluated by simultaneously recording stick movement and bending from high-speed video capture (1000 Hz) and puck acceleration from a triaxial accelerometer positioned inside the puck. Data were analyzed with a one-way ANOVA for several dependant variables including final puck velocity, stick shaft bending, blade-puck contact time and stick kinetic energy. The results indicated that: (1) the puck velocity was influenced by skill level, blade-puck contact time and stick bending energy but not puck acceleration. Further studies are needed to address the influence of events before and after blade-puck contact as well as the strength of the player on the mechanical energy and impulse given to the puck.

Full text

Abstract:

Ice hockey facial protectors are essential to prevent eye and dental injuries but must also not encumber vision and, in turn, players' performance. The purpose of this study was to investigate the effects of three different facial protection conditions on response time (RsT) and kinematics in a goal directed pointing task: helmet (control), visor, and cage. A 13 light target array and six-camera Vicon Mx system were used to collect response time and kinematic data. Subjects recruited were 16 male and 12 female varsity ice hockey players (n=28). Results demonstrated that although kinematics remained largely unaffected, throughout the visual field test RsT increased significantly with the cage (23 ms) as well as delayed head movement for both the visor (14 ms) and cage (18 ms). These differences may well represent a functional disadvantage to a player's performance given the dynamic, open environment where multiple players contest for puck possession. In summary, further research is warranted to achieve both optimal performance and safety.

Full text

Abstract:

The purpose of this thesis was to examine the three dimensional kinematic differences between elite and recreational ice hockey players while performing a stationary slap shot. Ten subjects, five elite-level players and five recreational players, each performed five stationary ice hockey slap shots. Data were collected using the UltratrakRTM electromagnetic system (Polhemus Inc., Burlington, VT, USA) at 60 Hz. Kinematics of the torso, arms and hockey stick were examined using a multiple analysis of variance (MANOVA). The results indicated that: (1) the elite subjects shot significantly (p < 0.05) faster due to the translational movement aspect of the stick; (2) the proximal to distal kinematic chain sequence of the elite subjects was better than the recreational subjects; and (3) the elite subjects showed less variability in stick movement within groups, than the recreational subjects. Further studies are needed to address kinematics of the lower limbs and of different ice hockey stick skills.

Abstract:

This thesis was to examine the interaction of players' skill level, body strength, and various types of stick construction and stiffness on the performance of the hockey shots. Forty subjects were tested, and each subject performed the slap and wrist shots with different stick shaft constructions and stiffness. Shot mechanics were evaluated by simultaneously recording of ground reaction forces, stick movements and peak puck velocity. Data analyzed with a 4-way ANOVA for several dependent variables. The results indicated that: (1) the slap shot was faster than the wrist shot corresponding to greater vertical force, stick bending and hand placement; (2) the puck velocity was influenced by skill level and body strength not stick type; and, (3) the skilled players generated greater vertical force and stick bending by adjusting their hand positions. Further studies are needed to address the specific stick material and construction properties.

Full text

Abstract:

The Romans were known for taking technology and advancements from other peoples they encountered and making them their own. This pattern holds true in military affairs; indeed, little of the Roman military was indigenously developed. This dissertation looks at the origins of the Roman's mainline weapons systems from the beginning of Roman Republic expansion in the fourth century BC to the abandonment of Western-style armaments in favor of Eastern style ones beginning in the late-third century AD. This dissertation determines that the Romans during that time relied predominately on the Celtic peoples of Europe for the majority of their military equipment. One arrives at this conclusion by examining at the origins of the major weapons groups: armor, shields, spears, swords, and missile weapons. This determination is based on the use of ancient written sources, artistic sources, and archaeological sources. It also uses the large body of modern scholarship on the individual weapons. The goal is to produce a unified work that addresses the origins of all weapons in order to see if there is an overarching impact on the Roman military from outside cultures. When one studies whence the weapons that ended up in Romans hands originated, a decided Celtic influence is easily found. That does not mean the Romans did not advance those weapons. The Romans proved very adroit at improving upon the basic designs of others and modifying them into new forms that met new needs. The Romans just did not develop their own technology very often. As a result, the Celts will exert a strong impact on the Roman military culture as it develops from 400 BC until it is overtaken by Eastern influences in the late 200s AD.

Full text

Abstract:

The purpose of this study was to investigate whether ice hockey facial protectors can decrease overall head acceleration during blunt impacts as well as to identify if attenuation differences exist between visors and cages. Commercial models of three cages and three visors were assessed. Blunt impacts were simulated permitting the measurement of peak accelerations (PA) within the surrogate head form. Results indicated that indeed face protectors in combination with helmets substantially reduced PA during blunt impacts within threshold safety limits (below 300 g's). In general, cages showed lower PA than visors (p=0.004). Differences between models were also observed during repeated impacts and impact site (p=0.0001, p=0.007). In conclusion, this study demonstrates that facial protectors function beyond their role in preventing facial injuries, complementing the role of the helmet in attenuating head deceleration during impact. Consequently, the utilization of facial protectors may reduce the severity and incidence of mTBI.

Full text

Abstract:

The exposure to fumes and gases is one of the hazards associated with welding operations. Apart from research conducted on the mechanism of fume and gas formation and the relationship between fume formation rates and common welding parameters, little is known about the exposure process during welding. This research project aimed to identify the factors that influence exposure, develop an understanding of their role in the exposure process and through this understanding formulate strategies for the effective control of exposure during welding. To address these aims a literature review and an experimental program was conducted The literature review surveyed epidemiological, toxicological and exposure data. The experimental program involved three approaches, the first, an evaluation of the factors that influence exposure by assessing a metal inert gas/mild steel welding process in a workshop setting. The second approach involved the study of exposure in a controlled environment provided by a wind tunnel and simulated welding process. The final approach was to investigate workplace conditions through an assessment of exposure and control strategies in industry. The exposure to fumes and gases during welding is highly variable and frequently in excess of the health based exposure standards. Exposure is influenced by a number of a factors including the welding process, base material, arc time, electrode, arc current, arc voltage, arc length, electrode polarity, shield gas, wire-to-metal-work distance (metal inert gas), metal transfer mode, intensity of the UV radiation (ozone), the frequency of arc ignitions (ozone), thermal buoyancy generated by the arc process, ventilation (natural and mechanical), the welding environment, the position of the welder, the welders stance, helmet type, and helmet position. Exposure occurs as a result of three processes: the formation of contaminants at or around the arc region; their transport from the arc region, as influenced by the entry and thermal expansion of shield gases, the vigorous production of contaminants, thermal air currents produced by the heat of the arc process, and ventilation; and finally the entry of contaminants into the breathing zone of the welder, as influenced by the position of the welder, the welders stance, helmet type, and the helmet position. The control of exposure during welding can be achieved by several means: through the selection of welding parameters that generate low contaminant formation rates; through the limitation of arc time; and by isolating the breathing zone of the welder from the contaminant plume through the use of ventilation, welder position or the welding helmet as a physical barrier. Effective control is achieved by careful examination of the workplace, the selection of the most appropriate control option, and motivation of the workforce.

Full text

Abstract:

This thesis describes a multi-channel millimeter wave radiometer control system that will be used for atmospheric water vapor and temperature profile retrievals. The system consists of four subsystems which provide a total of nine frequency channels, a steerable reflector to permit slant-path measurements at different zenith angles, and a host computer for analyzing the data. The nine channels span the water vapor and oxygen absorption lines in the 20 to 60 GHz range. A distributed processing architecture is implemented to control the system. Each of the subsystems employs a signal processor and a microcontroller, which are configurable from the host. The signal processor filters the receiver's output, while the microcontroller oversees the radiometer, accepts data from the signal processor and communicates with the host. The host executes a custom shell that allows it to concurrently accept data from the subsystems, position the reflector and execute user analysis programs.

Abstract:

The Naval Construction Force (NCF) performs construction projects in all areas of the world during both peacetime and war. While some of these projects occur in populated areas where project materials are readily available, many of these projects occur in remote areas or war zones, where project materials must be procured from the United States or elsewhere and shipped to the unit performing the construction. The construction scopes also vary from projects as small as concrete sidewalks to projects as large as full utility system installations, or complete facility and base construction. As a result of the diverse locations and project types that the Naval Construction Force experiences, the logistics of providing project material and construction equipment to multiple global locations is a major challenge. The Naval Construction Force still experiences delays and inefficiencies in supplying construction materials to its various projects and units deployed throughout the world, which in turn reduces the overall productivity of the deployed Construction Battalions. This research explores the current supply chain that the NCF has in place for obtaining construction project materials. It also explores the latest initiatives in information technology and construction supply chain management that are being applied in the commercial sector. The two systems are compared to determine what private practices and technologies can be applied to the Navy system to make it more efficient. Since the Navy is restricted by Federal Acquisition Regulations, and has unique funding streams authorized by Congress, it will not have the ability to fully operate as a private construction company, and these restrictions are addressed. The issue of outsourcing and privatization is also studied, and the feasibility of outsourcing the entire construction material process is considered.

Webster, James. "The perception of comfort and fit of personal protective equipment in sport." Thesis, Loughborough University, 2010. https://dspace.lboro.ac.uk/2134/6242.

Full text

Abstract:

During the design of sports equipment, the main focus is usually on physical performance attributes, neglecting key subjective factors such as feel and comfort. The personal protective equipment worn in sport is a typical example, where injury prevention has taken precedence over user comfort, but it is anticipated that with a new approach to the design process, comfort can be improved without sacrificing protection. Using cricket leg guards and taekwondo chest guards as an example, this study aimed to develop a systematic method for assessing user perceptions and incorporating them into the design process. Players perceptions of the factors that influence the comfort of cricket leg guards and taekwondo chest guards were elicited through the use of co-discovery sessions, focus groups and individual interviews, and analysed through an inductive process to produce a comfort model. The relative importance of each different comfort dimension was identified through the use of an online questionnaire utilising the analytical hierarchy process method. Through the combination of these methods, six general dimensions were identified with a weighting regarding the amount to which each one determines a user's perceived comfort. For both cricket and taekwondo, the majority of players ranked Fit as the most important factor affecting comfort. Experimental procedures were developed to objectively test the Fit of cricket leg guards, with regards to batting kinematics, running performance and contact pressure. These methods were combined with subjective assessments of leg guard performance, to determine if there was a relationship between users perceived comfort and objective test results. It was found that shot ROM and performance were not significantly affected by cricket leg guards, despite perceptions of increased restriction whilst wearing certain pads. Wearing cricket leg guards was found to significantly decrease running performance when compared to running without pads (p<0.05). In addition, it was found that the degree of impedance depended on pad design and could not solely be attributed to additional mass. These results correlated with the subjective assessment of three different leg guards, with respondents identifying the pad which had the largest influence on their running biomechanics and impeded their performance the most, as the most restrictive pad. Contact pressure under the pad and straps was also measured for four different leg guards whilst running. The results found that the top strap applied the greatest amount of pressure to the leg, especially at the point of maximum knee flexion. The peak pressure under the top strap was found to reach up to three times that of any other area of the pad. These results were reflected in the subjective assessment of the leg guards, with all nine subjects identifying the top strap as an area of discomfort for certain pads. The results also suggested there was a preference for pads with a larger more consistent contact area, as pad movement was perceived to increase when contact area variation was greater. Finally the results from this research were used to develop a product design specification (PDS) for a cricket leg guard, specifying size, mass, contact pressure and shape. The PDS was used to develop a concept design which would maximise comfort, whilst maintaining protection.

This study evaluated the mechanical durability of ice hockey helmets for multiple impacts at defined energy levels. A monorail drop testing apparatus was used to conduct controlled impact tests according to the CSA standard (CAN/CSA-Z262.1-M90). Five ice hockey helmet models were tested, for a total sample of 45 helmets. All helmets were impacted up to 50 times at each of in four different locations (i.e. front, right side, back, and crown), at one of 40, 50 or 60 J of kinetic energies. In general, by increasing the impact energy, the impact acceleration attenuation properties of the helmets was decreased significantly (from 4% to 80%). Although all the helmets meet the CSA standards, attenuation properties were found to be substantially reduced beyond three repeated impacts and above 40 J impact energy. In particular, all helmets showed effective multiple impact attenuation properties at the crown, front, and rear sites; however, poor multiple impact attenuation durability was evident at the side.

Abstract:

The purpose of this study was to examine the effect of puck mass on shot velocity of female ice hockey players. The contributions of upper body strength and skill level to shot velocity were also examined. Female varsity and recreational players (n = 29, age = 21.3 yr) performed shooting tests on ice. The participants shot 20 light weight (5 oz) and 20 regulation (6 oz) pucks, using 4 different types of shots (standing wrist shot, standing slap shot, skating wrist shot, skating slap shot). The on-ice tests were followed-by 3 musculoskeletal tests; predicted 1 repetition maximum (1 RM) bench press, hand grip, and sit-ups. The light weight puck resulted in a significantly higher velocity compared to the regular weight puck (P < 0.05). The average shooting velocity was 1.4 km/h higher with the light weight puck compared to the regular puck (69.8 vs. 68.4 km/h) based on overall means (4 shots x 2 pucks). Positive correlations were found between overall shot velocity and musculoskeletal tests of hand grip (r = 0.81), predicted 1 RM bench press (r = 0.77), and sit-ups (r = 0.48). These results are discussed in relation to literature on the women's ice hockey and physiology.

Abstract:

Nitrogen oxides control the photochemical production of ozone 03 in the lower atmosphere and influence the concentration of the hydroxyl radical HO in the troposphere. As an important member of the nitrogen oxide family, N02 plays a significant role in serving as the only known source of ozone (through photolysis) in the lower atmosphere and as sink for HO via formation of nitric acid. Therefore, accurate measurements of nitrogen dioxide are essential for the understanding of the processes that determine the distribution of tropospheric ozone and for assessing the impact of human activity on the troposphere. Although reliable and sensitive techniques for the direct measurement of nitric oxide NO have been developed, these results could not be fully applied to direct N02 measurements. The purpose of the present study was to further develop a low pressure laser-excited fluorescence technique for measuring N02 by introducing the idea of a Two-Chamber-Fluorescence-Cell. Theoretical considerations of the performance of such a cell and the flow regime within the cell were done in order to assess the optimum cell design and the conditions for optimum operation. Measurements on a provided two-chambered test cell were done to verify the theoretical predictions made. This test cell has been explored with a Nd:Y AG pumped dye laser (100mW@564nm, 30Hz) and a supplied N02 concentration of lOOppm. The theoretical results suggest that the concept of a Two-Chamber-N02- Fluorescence-Cell yields an improved sensitivity compared to present direct techniques for measuring N02 In addition, experimental results give a better understanding of how to realize the initial idea of an operating Two-Chamber-N02- Fluorescence-Cell.

Abstract:

The purpose of this research was to develop three real-time adaptive temperature controllers for hyperthermia heating systems. Each scheme is made adaptive by using a transient Gaussian estimation routine to estimate the tissue blood perfusion and by then using these estimated values either in an optimizing routine, or in an observer, or in both. The optimizing routine uses a steady-state Gaussian estimation technique to optimize the power distribution until the best possible match is obtained between the steady-state temperatures predicted by a treatment model and a prespecified ideal temperature distribution. The observer uses a treatment model to control unmeasured locations. The first adaptive control scheme uses the optimizing routine alone, the second uses the observer alone and the third uses both the optimzing routine and observer. The performance of each of the adaptive control schemes is compared to a standard proportional-integral-derivative (PID) control scheme for one-dimensional simulations of typical treatments. Results comparing the deviation of the controlled temperature distribution to the ideal desired temperature distribution for all locations and all times indicate that the adaptive schemes perform better than the PID scheme. It can be concluded that adaptive control yields improved performance if good a priori knowledge of the treated region tissue and perfusion region boundaries is available. While these control schemes were designed for eventual implementation on a scanned focused ultrasound hyperthermia treatment system, the techniques are applicable to any system with the capability to vary specific power with respect to location and with an unknown distributed energy sink proportional to the temperature elevation.

Abstract:

Recent advancements in corrosion-resistance coating technology has reduce the use of environmentally harmful compounds such as Hexavalent Chromium by replacing Hexavalent Chromium in primers and topcoat. However, marking inks were neglected in the process. Products such as Enthone 50 series are still widely used, which contain compounds such as lead, hexavalent chromium, bisphenol A (BPA), Cadmium Sulfide, and more. Excluding catalyst compositions in Enthone, the chemicals in the ink alone contained three reproductive toxicant and numerous carcinogens. Therefore, it was essential to search and validate the performance of potential marking ink that would meet the standards in military applications. Eleven products were tested, and two products were recommended for use: Sherwin Williams MIL-PRF-22750 Type I and Union Ink Uniglaze. Both products contain at most one carcinogen ingredient and no reproductive toxicant. Both products passed MIL-STD 202G Method 215K solvent test, MIL-STD 202G Method 107G thermal shock test, MIL-STD-810G, Method 507.5 humidity test, cleaning system test, ASTM D3359, measure adhesion by tape test.

Abstract:

This work sought to explore, evaluate and then improve the process of development for personal Military Load Carriage Equipment (MLCE), such as rucksacks. It was suspected that current MLCE had a number of user interaction deficiencies which should have been addressed during development. Three research questions were posed to determine: the influences on MLCE development, what needed improvement in MLCE development and how MLCE development could be improved. The work was based on eight studies conducted in three phases: the first to explore MLCE development and the observed deficiencies, the second to evaluate MLCE development, and the third to improve it. The chosen research strategy was henomenological, using a grounded theory methodology within which phenomena could emerge. Grounded theory approaches were adopted for this research because they were the best way in which to access the design domain. The research was framed within cycles of reflective action research to enable the researcher to re-orientate the enquiry to make the best use of the research opportunities that arose from the organisational context in which the research was sited. An initial investigation into the development of in-service equipment was done via a comparative case study, using documentary analysis and interviews with authorities in the field. Through this investigation it became clear that MLCE development was based on heuristics and tacit knowledge of manufacturing techniques, and collaboration between professional groups, including: materials / manufacturing, human systems, project management and military personnel. Deficiencies within MLCE development, determined through the comparative study, were validated against current practice through a further case study and additional evaluations. A comparison of outputs from these studies was then reviewed in a grounded manner to gain a holistic understanding of MLCE development. The interaction and importance of the various influences on MLCE development was then better understood, in particular the inadequate understanding of MLCE user needs, and requirement specification. To refine the possible avenues and target audience for an improvement of MLCE development stakeholder interviews were undertaken to develop a better understanding of how military user needs were gathered and applied. Following the interview survey, a tool was developed to analyse video and audio data of soldiers operating with MLCE on current operations. The tool was then reviewed by a panel of MLCE developers and stakeholders. The panel thought that the tool had a number of benefits to MLCE development: improving understanding of soldier environments, improved quality and reliability of information used in development, and as a conduit for concept evaluation. The research has provided a novel perspective on MLCE development, and provided a number of avenues upon which subsequent research could focus. The research has been able to make original contributions to understanding, albeit in a manner limited by the methodologies used.
