Abstract:

Drilling is a standard process for producing holes in metal materials. With an increased hole depth the demands increase on both machine and tool. Deep hole drilling is a complex process which ischaracterized by a high metal removal rate and hole accuracy. A hole deeper than ten times the diameter can be considered a deep hole which requires a specialized drilling technique. During adeep hole drilling process, the forces generated on the deep hole drill give a rise to a resultant radial force. The resultant radial force pushes the drill in a radial direction during a drilling operation. The ra

Abstract:

Проточна частина вільновихрового насоса (СВН) виконана так, що робоче колесо (РК) знаходиться в циліндричній розточці корпусу в стороні від основного потоку, а перед робочим колесом утворена вільна камера, через яку проходить основна частина потоку рідини. Повна симетрія розташування РК в циліндричній розточці корпусу призводить до рівномірного розподілу тиску в зазорі між торцями лопатей по зовнішньому діаметру і внутрішнім діаметром циліндричної розточки. Тому, таке конструктивне виконання має виключити існування радіальної сили.

Abstract:

<p>Induction machines convert more than 55% of electrical energy into various other forms in industrial and domestic environments. Improved performance, especially by reduction of losses in induction machines hence can significantly reduce consumption of electricity. Many design and control methods are adopted to make induction machines work more efficiently, however certain design compromises are inevitable, such as skewing the rotor to improve the magnetic noise and torque characteristics increase the cross current losses considerably in a cage rotor, degrading the efficiency of the motor.

Understanding of plasma confinement modes is an essential component in development of a fusion reactor. Plasma confinement directly relates to performance of a fusion reactor in terms of energy replacement time requirements on other design parameters. Although a variety of levels of confinement have been achieved under different operating conditions in tokamaks, tokamak confinement is generally identified as being either Low (L-mode--poor confinement) or High (H-mode--good confinement) In operation of a tokamak experiment, the plasma confinement condition generally changes from L-mode to

Abstract:

Dynamic characteristics of a paper machine roll have been widely investigated for decades. Vibration of the rolls decrease the paper quality and excites the structures of the paper machine. Therefore, vibration must be avoided and kept at its minimum. Vibration of a rotor develops periodic radial bearing forces, which are connected to the amplitude and the frequency of the vibration. Vibration based forces are unnecessary dynamic forces, which increase the bearing load in addition to unavoidable rotor mass and the external loads of the process.

The radial force control has been widely investigated for a variety of machine topologies aiming at the reduction of the mechanical stress on bearings as well as the overall vibration. Furthermore, it can be also applied to bearingless drives where the force control can be exploited to suspend the rotor element. Traditional radial force control techniques rely on two independent sets of windings dedicated to torque and suspension force, respectively. However, different winding structures can be employed to reduce the overall system complexity. Multiphase machines, in particular, offer the poss

However it is unknown especially to southern Sweden how trees in a continuous cover forestry system react to common silvicultural measures such as thinning.

The rising public awareness of climate change and urban air pollution has been one of the key drivers for transport electrification.

Specifically, the fractional-slot and concentrated-winding configuration is widely adopted due to its distinctive merits such as short end winding, low torque pulsation, and high efficiency. The vi

Abstract:

This thesis tells the story of an historical tradition of radical literacy and literature that is defined as the British radical literary tradition. It takes the meaning of literature at its broadest understanding and identifies the literary and educational relations of what E.P. Thompson terms 'the making of the English working class' through its struggle for literacy and freedom. The study traces the developing dialectic of literary radicalism and the emergent hegemony of capitalism through the dissemination of radical ideas in literature and a groundswell of public literacy. The proposed ra

Abstract:

Les polymères à empreintes moléculaires (MIPs) sont des matériaux synthétiques contenant des cavités capables de reconnaître spécifiquement une molécule cible. Ils se présentent comme une alternative intéressante face aux anticorps biologiques en raison de leur meilleure stabilité chimique et physique, leur meilleure disponibilité et leur moindre coût. Traditionnellement, les MIPs sont synthétisés par polymérisation de monolithes, qui sont ensuite broyés mécaniquement, engendrant des particules de taille micrométrique et de formes irrégulières. Durant ces dernières années, de nombreuses techni

Abstract:

Monterey pine (Pinus radiata), a native tree to California and two Mexican islands, is important both ecologically and economically. Outside native stands, Monterey pines are grown for landscaping in California and on plantations around the world. Pitch canker, a disease caused by the fungus Gibberella circinata Nirenberg & O’Donnell (Fusarium circinatum Nirenberg and O'Donnell) is threatening the survival of Monterey pines. The disease currently affects Monterey pines in many parts of the world including the native stands. No effective chemical or biological control is available but some Mont

Abstract:

This diploma thesis deals with problematics of the radial force effect on the runner and possibilities of the force reduction. Some pump modifications were proposed and changes of radial force magnitude in reverse blocking state and optimal flow state were examined in consequence. Following investigation was focused on the new modifications regarding to the pump efficiency and its characteristics stability. All results were carried out using the Solidworks, the Fluent and the Microsoft Excel software.

Abstract:

Tree-rings were analyzed to assess the relative importance of slope position and aspect as determinants of the climate-sensitivity of sugar maple and white oak radial growth. Tree size, crown condition, forest and soil composition, and site indices were assessed to document environmental differences between site-types and to verify similarity of stands within the same site-type. Climate-sensitivity was assessed using mean between-tree correlation, principal components analysis, mean sensitivity, regression analysis, and analysis of radial growth decline after severe drought.

Abstract:

This thesis deals with the radial forces acting on the impeller of a centrifugal pump. It focuses on the centrifugal pump type BETA 26. It addresses forces acting on the pump shaft. These forces are converted into the impeller. The most extensive part of this thesis is devoted to the experimental measurement and evaluation. The results are summarized and processed graphically.

An understanding of water availability and its variation in space is fundamental to the implementation of increasingly site-specific management regimes that have the potential to greatly improve productivity across sites in the region. Fifteen plantation compartments situated on water shedding sites were identified w

Abstract:

Depuis 30 ans, les mesures annuelles de déficit foliaire des arbres sur la partie française du réseau européen de suivi des dommages forestiers (ICP Forests, niveau 1), constituent la base du suivi de l’état de santé des forêts. Pourtant, l’utilisation du déficit foliaire comme indicateur de l’état de santé de l’arbre est régulièrement remise en cause pour des raisons méthodologiques mais aussi en raison du manque de connaissances sur le déterminisme du déficit foliaire et de son impact fonctionnel sur l’arbre. Dans ce contexte, au travers des notations de déficit foliaire de 9 essences (feuil

Or, les propriétés viscosifiantes des polymères dépendent de leurs masses molaires. L’enjeu de ce travail de thèse a donc été de mettre en place de nouvelles méthodes pour la détermination de larges distributions en masses molaires et de grande dispersité, caractéristiques propres aux échantillons d’intérêt industriel dans le domaine pétrolier.

Мета дослідження – розглянути осьові коливання ротора, обумовлені його радіальними коливаннями. Тут же виводяться лінеаризовані рівняння спільних радіально-осьових коливань найпростішої одномасової моделі жорсткого ротора з автоматичним врівноважувальним пристроєм.
