Mining Help Desk Emails for Problem Domain Identification and Email Feature Engineering for Routing Incoming Emails
… steps done on email from the help desk domain, such as removal of different types of noise elements and removal of stop words using a customized stop word list, and the outcome of each of these pre-processing steps.

Relationship analysis : improving the systems analysis process
… capture the relationship structure of the problem domain. Whereas, other analysis techniques lightly address the relationship discovery process, Relationship Analysis is the only systematic, domain-independent analysis technique focusing exclusively on a domain's relationship structure. The …

Identification of chemical species using artificial intelligence to interpret optical emission spectra
… on representative data within a particular problem domain and generalise over a set of data make them efficient predictive models. One problem domain that contains complex data that would benefit from the predictive capabilities of ANN’s is that of optical emission spectra (OES). OES is an …

ADVANCED IMPLEMENTATIONS OF THE ITERATIVE MULTI REGION TECHNIQUE
<p>The integration of the finite-difference time-domain (FDTD) method into the iterative multi-region (IMR) technique, an iterative approach used to solve large-scale electromagnetic scattering and radiation problems, is presented in this dissertation. The idea of the IMR technique is to divide a …

An Evolutionary Based Methodology for Representing and Evolving Structural Design Solutions
… synthesis of design solutions in unstructured problem domains. The implicit redundant representation genetic algorithm (IRR GA) used redundancy to support the self-organization of the representation by encoding a variable number of location independent design parameters. Using an unstructured …

A substrate for accountable layered systems
… many novel and difficult software engineering problems. Some of these problems can be ameliorated by erecting the system on a substrate that implicitly supports tracing the behavior of the system to the data and through the procedures that produced that behavior. Good traces make the system …

Multiscale modelling and an experimental investigation on size-scale effects in concrete
… presumption does not hold true if the considered problem domain is smaller than the RVE. The size of material constituents in relation to the dimension of the specimen can then not be considered negligible and the interaction between the constituents needs to be addressed. In this context, …

Connotational Subtyping and Runtime Class Mutability in Ruby
… allows for a more precise representation of a problem domain with logical objects that have variable behavior. Two approaches to supporting connotational subtyping in the Ruby programming language were implemented: a language-level implementation using pure Ruby and a modification to the Ruby …

Mobility, AAA, security, privacy : a unified architecture to enable real-world host and network mobility
… the importance and attention that this problem domain requires from the research community. Host and network mobility protocols have been developed in recent years to provide constant connectivity to commuters' mobile devices, moving individually or as a group, but are yet to be widely …

Feature-based Approach to Bridge the Information Technology and Business Gap
The gap between business goals (problem domain), such as cost reduction, new business processes, increasing competitive advantage, etc., and the supporting Information Technology infrastructure (solution domain), such as the ability to implement software solutions to achieve these goals, is complex …

A reduced visibility graph approach for motion planning of autonomously guided vehicles
… is concerned with the robots' motion planning problem. In particular it is focused on the path planning and motion planning for Autonomously Guided Vehicles (AGVs) in well-structured, two-dimensional static and dynamic environments.<br/><br/>Two algorithms are proposed for solving the …

The application of knowledge based systems to the abstraction of design and costing rules in bespoke pipe jointing systems
… pipe jointing systems. An overview of the problem domain is provided and the findings from a literature review on knowledge based systems and applications in manufacturing were used to provide initial guidance to the research. The overall investigation and development process involved the …

Penware Panther: An embedded computer system for real-time applications
… (OO) modeling approach is taken, which improves problem domain abstraction as well as system's stability in the presence of changes. The Unified Modeling Language (UML) is used throughout the design to express the constructs and relationships among them. This work contributes, mostly to the …

Object-oriented data modeling
… and to a lesser extent, the structure of a problem. Semantic data models describe structure and semantics. This thesis unifies the behavioral focus of the object-oriented paradigm with the structural and semantic focus of semantic data models. The approach contains expressive abstractions to …

An implementation of the ground structure method considering buckling and nodal instabilities
… an optimal solution for the layout optimization problem. The problem domain is discretized with a union of highly connected members, which is called a ground structure. The objective typically is to minimize the total volume of material while satisfying nodal equilibrium constraint and predefined …

Telematic composition
… of the medium. Practical issues in the problem domain of networked ensemble performance were examined through a series of experimental research sessions, showing that latency affects the perception of interactivity and presence and strongly coerces musical results. Visual representations …

FOCES: An experimental expert system to select appropriate foster care homes for children
… was greatly influenced by unique features of the problem domain. Among the key concerns were: unresolved questions within the social work profession about foster home selection and evaluation, serious methodological and philosophical difficulties associated with defining a good "person-environment …

Behavioural synthesis of analogue integrated circuits
… GAs are shown to be currently ill-suited to the problem domain of analogue circuit synthesis. The problem of SPICE non-convergence on the GA is also considered.

Trust-based design of human-guided algorithms
… it is difficult to model continually changing problems and incorporate human objectives into the solution. Human-guided algorithms (HGAs) harness the power of sophisticated algorithms and computers to provide flexibility to the human decision maker to model correctly and dynamically the problem …
