Entropy and cycles
This body of works subject and focus point is the cyclical nature of matter and the forces therein. There have been explorations of this concept on all fronts including metaphysical philosophy, science, and art. It is the recurring realization of matter as a cyclical form being driven by unseen …

Finding Hamiltonian Cycles
<p>Finding a Hamiltonian cycle in a graph is used for solving major problems in areas such as graph theory, computer networks, and algorithm design. In this thesis various approaches of Hamiltonian cycle algorithms such as backtrack algorithms and heuristic algorithms, their basic ideas, and their …

Behavioural Macro-Financial Cycles
… importance of proximal drivers of house price cycles: I find that consumption demand is the most important driver but asset demand is also relatively important. Therefore housing cycles are likely to arise from the partially behavioural reactions to changes in housing demand.

On cycles in directed graphs
… cycle. We also deal extensively with short cycles, showing that for each l > 4 every sufficiently large oriented graph G with minimum indegree and minimum outdegree at least |G| / 3 + 1 contains an l-cycle. This is best possible for all those l > 3 which are not divisible by 3. Surprisingly, …

The Cycles of aMaízing Things
… feedback between them for the re-transforming cycles of maíz. The crucial concern driving this exploration is how maíz and humans are ingrained into each other's systems — re-configuring methods, spaces, and forms of display. The display refers not only to maíz as a ‘product’ but as a …

Tracking Electrons Through Element Cycles: Linking Fe, C, and O Cycles Through Shared Reactive Oxygen Species
… states in the biosphere. We hypothesize these cycles are co-dependent through the intermediacy of reactive oxygen species (ROS), where both radical and non-radical species are potential electron carriers between Fe and C. In all but major river systems, the freshwater/saltwater mixing that …

Biomass Integrated Gasification Combined Cycles (BIGCC)
Conversion of biomass to energy does not contribute to the net increase of carbon dioxide in the environment, therefore the use of biomass waste as a clean and renewable fuel source is an attractive alternative to the use of fossil fuels. Biomass can be converted to energy via direct combustion or …

Melatonin and seasonal cycles in muskoxen
… in spring on the timing of subsequent seasonal cycles was examined. (Abstract shortened by UMI.)

Une investigation empirique des cycles Kondratieff
… de cette étude consiste à vérifier si les cycles de Kondratieff ont vraiment existé. Trois objectifs découlent de ce but principal. Le premier objectif est d'exposer les raisons qui expliquent la divergence des résultats entre les différentes investigations empiriques. Le deuxième porte sur …

Humidification Processes in Gas Turbine Cycles
… smaller each decade and therefore, thermodynamic cycles have become more interesting for power producing units. One of these cycles is the evaporative gas turbine cycle, also known as the humid air turbine. This thesis presents a theoretical model developed for the humidification tower in an …

Universal Cycles for Some Combinatorial Objects
… of de Bruijn's original theorem, namely that the cycles bearing his name exist for<em> n-letter</em> words on a<em> k-letter</em> alphabet for all values of <em>k,n,</em> to prove that we can create de Bruijn cycles for multi-sets using natural encodings and<em> M-Lipschitz n-letter</em> words and …

The Song Cycles of Louis Aubert
Six Poemes Arabes is Louis Aubert's largest and most orchestral work for voice and piano. The poetry, taken from Franz Toussaint's Jardin des caresses is highly evocative, and frequently borders on the erotic. A young man has a dream that he is seeking his beloved, and throughout the cycle is …

Modeling and prediction of sunspot cycles
… on the sample means and variances for all past cycles. We compare our models to simulation results for many models we found in the literature including autoregressive (AR) models, subset AR (SAR) models, and related nonlinear models including a threshold AR model, transformed by squaring (TTAR …

Consumer confidence and business cycles : a casy study for the Netherlands : are business cycles driven by animal spirits?
… confidence index in forecasting business cycles in the Netherlands. Furthermore, the possible heterogeneity regarding the information content of individual questions is addressed, and it is investigated whether this information can be attributed to the information view or to the animal …

Multi-Generational Cycles of Poverty and Prosperity
This thesis researches racial economic disparities over time and the historical factors that have allowed such starkly visible differences to persist for multiple generations. It also controls for routine rationalizations for these economic disparities--education and income levels--to dispel them …

A Model of Workplace Anger Response Cycles
… proposes a Model of Workplace Anger Response Cycles (WARC). The model shows that the outcomes of anger expression are influenced by the interaction of the expresser and a social partner and the context where this interaction occurs--e.g. organizational culture, emotional climate, and anger …

Co-linear Chaining on Graphs With Cycles
… class of graphs that are narrow and have no cycles, i.e. directed acyclic graphs (DAGs) with small width, by Mäkinen et al. (ACM Transactions on Algorithms, 2019). Pan-genome graphs such as variation graphs satisfy these restrictions but allowing cycles may enable more general applications of …
