PROBABILISTIC METHOD IN RADIATIVE TRANSFER AND NEUTRON TRANSPORT PROBLEMS
… atmospheres many exact and approximate methods hc1ve so far been proposed. Of them, the probabilistic method of Sobolev and Ueno have proved to be particularly successful in handling both time-dependent and time independent transfer and transport problems in plane-parallel atmospheres. …

Applying the Herman-Beta probabilistic method to MV feeders
… energy resources. Classic deterministic methods which model load demand and generation with fixed mean values consequently turn out to be inadequate and inaccurate tools for the analysis of power flow in the uncertainty-filled system. Statistically based methods become more suitable for …

A method for the probabilistic method assessment of structures containing defects
… pressure vessels is deterministic. To enable probabilistic structural integrity safety cases of reactor pressure vessels to be carried out, a need for a new analysis of the statistical properties of fracture toughness is identified. Fracture is linked to the cracking of critically sized …

Probabilistic Methods
The Probabilistic Method was primarily used in Combinatorics and pioneered by Erdös Pai, better known to Westerners as Paul Erdos in the 1950s. The probabilistic method is a powerful tool for solving many problems in discrete mathematics, combinatorics and also in graph .theory. It is also very …

A quantitative assessment of nuclear weapons proliferation risk utilizing probabilistic methods
… nuclear reactor/fuel cycle concepts using a probabilistic method. The work presented details quantified proliferation resistance metrics of a pressurized water reactor (PWR), a PWR utilizing thorium as a fertile component of the nuclear fuel (Radkowsky Thorium Reactor-RTR) and a high …

Multimodal Assessment of Recurrent and Non-recurrent Conditions on Urban Streets
The methodology to measure the performance of urban streets was significantly revised in the latest edition of the Highway Capacity Manual (HCM 2010). Urban Streets, which include urban and suburban signalized arterial highways, typically serve the four modes of transportation (auto, transit, …

Drivable region detection for autonomous robots applied to South African underground mining
… for underground image classification. A probabilistic method based on the local entropy was employed. The entropy is measured within a fixed window on each frame in order to compute features used in the segmentation process. This research compares the results obtained from the entropy …

Reliability of Serviceability and Strength of Deep Foundations Embedded in (p-y) Sand Below Water Table Subjected to Lateral Cyclic Loading
… is a conservative approach. Reliability is a probabilistic method of analysis that provides consistent measurements for propagation of uncertainties and unifying framework for risk assessment. For this reason it is used instead of the factor of safety to provide a systematic account for the …

Resource allocation and load-shedding policies based on Markov decision processes for renewable energy generation and storage
… intermittency. In this thesis, we discuss a method to deal with this intermittency. In particular, by shedding some specific amount of load we can avoid a total system breakdown of the entire power plant. The load shedding method discussed in this thesis utilizes a Markov Decision Process …

Minimum description complexity
… length (MDL). The prior assumption in these methods is that the unknown true model is a member of all the competing sets. We introduce a new method of model selection: minimum description complexity (MDC). The approach is motivated by the Kullback-Leibler information distance. The method …

Statistical Analysis of Wireless Communication Systems Using Hidden Markov Models
… in wireless communication systems. HMMs are a probabilistic method which is useful for discrete channel modeling. The simulations done in the thesis verified a previously formulated methodology. Power delay profiles (PDP) of twelve wireless receivers were used for the experiment. To reduce the …

Wide-area egomotion from omnidirectional video and coarse 3D structure
This thesis describes a method for real-time vision-based localization in human-made environments. Given a coarse model of the structure (walls, floors, ceilings, doors and windows) and a video sequence, the system computes the camera pose (translation and rotation) in model coordinates with an …

Evaluation of Probabilistic Methodology for Predicting Satellite Tracking Resources
<p>This research evaluates a probabilistic methodology for estimating the ability of satellite tracking networks to provide tracking and data acquisition services to large constellations of satellites. This approach, developed by Hagar is evaluated using Monte Carlo simulations of optimal satellite …

Advancing semantic modeling: addressing coordination, interpretability, and data scarcity in domain representation
… Keyword Selection (DRKS) proposes a probabilistic method for extracting distinctive, context-aware keywords that capture the semantics of a target domain. Short-Text Topic Modeling (STTM) leverages large language models and prefix-tuned autoencoders to enrich sparse inputs and produce …

Toward In-Context Teaching
… we introduce a suite of models and evaluation methods we call AdapT. AdapT has two components: (1) a collection of simulated Bayesian student models that can be used for evaluation of automated teaching methods; (2) a platform for evaluation with human students, to characterize the real-world …

A probabilistic evaluation of tank ship damage in grounding events
… groundings or collisions. The current analytical method defined by the International Maritime Organization (IMO) applies probabilistic damage extents to proposed designs to determine expected oil outflows, which are compared to reference double hull vessels. The IMO method considers the effect of …

Generation system reliability with wind and solar power
… the system reliability performance based on probabilistic method. A capacity outage probability table (COPT) for conventional generating units is introduced first in this thesis. The conventional generator is represented which based on the well-known recursive technique. Then, the sequential …

Probability analysis of slope stability
… associated with a particular design situation.;A probabilistic approach to studying geotechnical issues offers a systematic way to treat uncertainties, especially slope stability. In terms of probability, uncertainties can be related quantitatively to the design reliability of a slope. Therefore, …
