LPTi has provided services to various clientele in the military and power generation sectors with significant success. LPTi’s high predictive accuracy is attributed to advanced material physics-based mathematical models that consider the effects of usage and materials processing variability into the microstructure of the component materials. Hence, XactLIFE provides quantitative predictive maintenance strategies for direct cost savings of 40% by optimizing parts replacement, refurbishment, and life extension while simultaneously maintaining safety and reliability of individual components. Cost savings of over US $40 Million were achieved for a land-based turbine fleet through deferred capital expenditures and reduced maintenance. LPTi has also significantly reduced the design life cycle time for emerging OEMs by offsetting prototype testing with simulation.
Engine owners, who maintain their fleets or seek independent opinions on OEM’s recommendations, benefit from LPTi's prognostics services.  LPTi has a strategic partnership with the NRC on material testing and has R&D collaborations with Carleton University, University of Ottawa, and ÉTS, Quebec.




Tutorial 1: Performance Prediction of Nonlinear Degrading Systems
Instructor: Professor Fai Ma, University of California at Berkeley, USA

Tutorial Abstract:
All structures exhibit nonlinear behavior and degrade when acted upon by cyclic loads associated with earthquakes, high winds, and sea waves. If the restoring force is plotted against the structural deformation, degradation manifests itself in the evolution of hysteresis loops. However, a fundamental theory of the evolution of hysteresis loops has not been developed.
In the absence of a model of hysteretic evolution or degradation, cyclic tests of structural joints and connections were routinely conducted around the world in the past thirty years. These tests have generated a substantial amount of experimental data on load-displacement hysteretic traces for wood, steel, and concrete structures. In the same period, generalization of the Bouc-Wen differential model of hysteresis permits curve-fitting of practically any hysteretic trace with a suitable choice of its thirteen control parameters. Using system identification techniques, it appears highly feasible to utilize the generalized differential model of hysteresis and the extensive database of experimental hysteretic traces to deduce a working model for degrading structures. A fundamental objective of this research project is to do just that.
Three specific tasks will be addressed in this presentation. First, a robust identification algorithm will be devised to generate models of degradation of a structure from its experimental load-displacement traces. This algorithm will be based upon the generalized differential model and the theory of genetic evolution, streamlined through sensitivity analysis. Second, it will be verified by experimentation that a model of degradation obtained by identification can be used to predict the future performance of a structure. Third, a procedure will be suggested to decompose a complex structure into a number of elementary joints and connections. Through such decomposition, the relationship between degradation of a complex structure and the degradation of its constituent joints and connections will be explored.
The significance of this project cannot be over-emphasized. Through brute-force identification of hysteretic evolution or degradation, it becomes possible to assess, for the first time in analysis, the performance of a real-life structure that has previously been damaged. There is not any other method that can predict the response of a nonlinear degrading structure well beyond its linear range.

Tutorial 2: Intelligent Health Monitoring of Rotating Machines
Instructor: Professor Nishchal K. Verma, IIT Kanpur, India

Tutorial Abstract:
Intelligent health monitoring of machines for early recognition of faults saves industry from heavy losses occurring due to untimely machine breakdowns. The goal of intelligent health monitoring is achieved with the help of Computational Intelligence. Computational Intelligence is a set of biological and linguistic tools that provide lot of freedom in efficiently addressing complex and challenging real world problems. In this tutorial, an intelligent framework to build effective data driven models for health monitoring will be presented. The tutorial will have three parts. In the first part, the tutorial will explain how Computational Intelligence techniques can be used for performing the primary operations of data pre-processing, feature selection and classification. In the second part, Sensitive Position Analysis will be discussed. Optimizing the number of sensors and finding optimal locations for placing sensors is a major concern for many health monitoring applications, especially with respect to reliability of diagnostic outcomes and cost efficiency. This tutorial will also give a brief history as to how this problem was first tackled with statistical analysis and later through Computational Intelligence techniques. The final discussion would be on making these technologies portable. Portable diagnostics is important because it can significantly cut down labor costs and also allow diagnosis in areas which are unreachable by humans. The tutorial will also illustrate how the entire technology as described earlier, was implemented for rotating machines such as Air compressor monitoring and Drill bit monitoring using smart phones, tablets, sensors, and also discuss the challenges faced in this endeavor.

Tutorial 3: Gearbox Fault Detection and Diagnosis
Instructor: Professor Chris Mechefske, Queen’s University, Canada

Tutorial Abstract:
Up to half of all operating costs in most industrial facilities are a result of maintenance. A range of different maintenance strategies may be applied to machines in order to assure optimum performance over the operational life at minimum overall cost. Which maintenance strategy is applied in a particular case depends on a host of factors. Typically, because gearboxes are relatively complex, expensive to repair or replace, carry high loads and are often used in situations that are critical to production, a condition based maintenance approach is employed. Condition based maintenance involves monitoring physical parameters over the course of machinery life and using these parameters to detect, diagnose and sometimes predict failure in a machine. Current techniques used for condition monitoring and fault detection applied to gearboxes are based on the analysis of vibration measurements, acoustic emission signals, and/or oil quality and wear particle assessments. These methods will be described, including their advantages and disadvantages. Particular attention will be paid to vibration based gear dynamic modeling and vibration signal analysis techniques. A review of some recently developed vibration signal analysis methods for enhanced gearbox fault detection and diagnosis will also be included.

Tutorial 4:  Fault Diagnosis of Induction Motor Using Machine Learning Techniques
Instructor: Professor Jaya Sil, Indian Institute of Engineering Science and Technology, India

Tutorial Abstract:
Real world data are often imprecise, inexact and redundant which limits applicability of the conventional methods in decision making or diagnosing the systems. Curse of dimensionality creates obstacle in training and run time phases of machine learning techniques applied to solve real world problems, where the exact parameters of relations are not necessarily known. During system modeling many attributes are used to ensure presence of all the necessary information without evaluating significance of the attributes. All attributes are not equally important and often redundant, therefore increasing complexity of the system. The goal of this research is to analyzing the data-sets from different perspective and summarizing it into useful information or knowledge. Large dimensional data consists of redundant as well as unique information, which are extracted by analyzing the data using machine learning algorithms. Different computational tools such as Rough-set theory, Fuzzy-set theory, Fuzzy-rough set and genetic algorithm are utilized for developing novel knowledge extraction algorithms. Machine learning is becoming a well adopted tool in the area of condition monitoring of electrical machines in the recent years. This novel approach of fault classification dominates traditional methods as it encompasses the wide range of behavioral operation and does not need any prior information about the induction motor parameters. The advancement in digital technology motivates researchers to develop an efficient memory based data driven approach for fault diagnosis. Discovering useful knowledge from motor current or vibration in the form of relevant features is a vital step to develop any fault diagnosis algorithm.
