An Information Value Approach to Route Planning for UAV Search and Track Missions
… a planning horizon when interrupted by Poisson random events, and (c) a modified Particle Swarm Optimization (PSO) algorithm for search missions that uses the prior target distribution in the generation of paths rather than just in the evaluation of them.</p> <p>UAV route planning is an …

Centers and centrality : reflections on French city design
… of France is a process due to a set of random events and deliberate choices. The very special relationship which was built throughout this process between the central governments of France and Paris was dramatically expressed in the design of Paris. Chapters I and II look at the history …

Electromechanical Wave Propagation in Large Electric Power Systems
… the disturbances initiated by faults and other random events propagate in the continuum. This dissertation presents one-dimensional and two-dimensional discrete models to illustrate the propagation of electromechanical waves in a continuum system. The more realistic simulations of the …

Constitutive Relations Among Conflict, Power, and Change in Complex Organizations: An Ethnographic Study of a Government Research and Development Laboratory
… of organizational practices and the entry of random events that changed the course of the conflict. These findings suggest that most received views of conflict--as an outcome of organizational processes--are far too limited. Rather, conflict is an essential dimension of the on-going process of …

An alternative optimization model and robust experimental design for the Assignment Scheduling Capability for the Unmanned Aerial Vehicles (ASC-U) simulation
… coverage may degrade in the presence of adverse random events. Integer programming, experimental design, and an innovative Optimized Flexible Latin Hypercube (OFLH) design are used to evaluate a representative sample from an Army 2018 scenario. The conclusions suggest the following: the …

Random growth of interfaces: Statistical analysis of single columns and detection of critical events.
… paper is focused on the interesting field of the random growth of surfaces and interfaces, which finds application in physics, geology, biology, economics, and engineering among others. In this part it is studied the random growth of surfaces from within the perspective of a single column, namely, …

Quality improvement, inventory management, lead time reduction and production scheduling in high-mix manufacturing environments
… Schedule delays can be caused by a variety of random events that occur in machine shops, such as machine failures or operators falling ill. By selecting a Shop Capacity Buffer of 90%, a 90% on-time completion rate should be observed. This new method would achieve improved results from the 75% …

Bell inequalities in cardinality-based similarity measurement
… Bell-type inequalities regarding at most four random events of which not more than two are intersected at the same time are presented in this work and are reformulated in the context of fuzzy scalar cardinalities leading to related inequalities on commutative conjunctors. It is proven that some …

Temporal Patterns of Co-occurrence between Children's Self-regulatory Behaviour and their Private and Social Speech
… which may also contain other temporally random events. These recurring temporal patterns are then contextually analysed, considering the pragmatic content of the speech involved and the goal-directedness of the behaviour towards a specific goal of the episode. Goal-directed episodes of …

Stochastic hub and spoke networks
… require responses to many different fixed and random events. Therefore modeling the question of what is an optimal hub and spoke network structure and finding an optimal solution is very difficult. Due to this, many researchers and practitioners alike make several assumptions and …

Essays on the dynamics of qualitative aspects of firms' behavior
… firm heterogeneity, modeled by means of random effects, is not significant in explaining exit decisions by firms. Firms' attrition is more likely to result from random events at the time of exit. CHAPTER 2 AN EMPIRICAL INVESTIGATION ON THE DYNAMICS OF QUALITATIVE DECISIONS OF FIRMS …

Confronting the Black Swan: A Case Study of Corporate Learning
… creation process. In addition, consequences from events external to the firm are assessed to determine their impact on knowledge creation and corporate learning. Summary The study used knowledge creation theory to understand how internal behaviors and external events affected corporate learning …

Ancestral Genome Reconstruction in Bacteria
… on either detailed modeling of evolutionary events or edit distance computation, both of which can be computationally prohibitive for large data sets. Hence, most of these methods can only be applied to a small number of features and species. In this dissertation, we describe the design, …

Novel Integer Optimization Methods and their Applications in Biomass Supply Chain and Power Dominating Set
… system to be observed and known distribution of random events, the IO formulation is proposed to satisfy the reliability requirement and meet some other problem-specific restrictions at the same time. In the work, the connectivity of the subgraph constructed by PMUs is also guaranteed for better …

Ensuring reliable and secure deployment of emergent workloads on modern microprocessors
… and security guarantees, protecting against both random events and intentional threats. Physical phenomena, such as hardware faults, pose a challenge to dependable systems, as they can undermine both reliability and security. While these challenges have been extensively studied in the past, recent …

Pedestrian safety at urban mid-block crossings
… safety practitioners. Pedestrian crashes are not random events. They indicate not only an underlying environmental effect but also behavioural issues related to risk-taking. For this reason, this research aimed to obtain a comprehensive insight into pedestrian behaviour and factors that impact …

L'impatto degli eventi casuali nei sistemi sociali: dagli sport individuali alle epidemie
Lo studio dei sistemi sociali nell'ambito della scienza della complessità è molto diffuso. Tra tutti i fenomeni che si possono esaminare, il fenomeno "rich-get-richer", noto anche come "effetto San Matteo", è particolarmente rilevante perché è essenziale per comprendere le dinamiche sociali …

Four Essays on Inventory and Supply Chain Management
… intermittent demand surges caused by planned or random events, including marketing campaigns, new product introductions, and natural disasters. To deal with such challenges, a firm can employ base contracts (“reserved instances” with standard length terms) to meet the base demand, complemented by …

The Theological Significance of the Relations of Freedom and Time in the Sciences and Humanities: An Evaluation of the Contributions of David Bohm and Pauli Pylkko
… features exhibited in nature, and that randomness plays a critical role. He also dismisses the idea of any residual 'timeless' platonic realm. Freedom and time are fundamentally constituted by their relationship to the interconnected or nonlocal yet locally manifested random events of …
