The least squares polynomial regression constraints program LSPRWC presented in this report is a computer code written to perform a least squares polynomial regression on a given set of data pairs or observations with the option to impose constraints on the regression polynomial. The FORTRAN 77 computer program listing, as well as detailed information on theory, program structure, and limitations, are given along with two sample cases.

In this project, we propose to research the methodology for constructing adaptive computer-aided education systems for mammography. Improved mammography education could lead to improved benefit of mammography to breast cancer care and in turn to decreased mortality from the disease. The project includes: Observer studies to collect reading data from radiology trainees; Extraction of image features (human- and computer- based); Statistical modeling of the reader data to discover patterns in their error making; Development of methodology for adaptive training that utilizes the constructed models. The proposed adaptive system could improve education in mammography. This may in turn result in improved benefit of mammography in breast cancer detection and lower mortality associated the disease.

VisLab has been pioneering the world of autonomous driving since its early years; in 1998 VisLab organized one of the most innovative experiments for that period: a passenger car was equipped with sensing and actuation devices and was tested with autonomous steering along a 2000+ km on Italian highways [5].

Chapter reviews the solutions used in diagnostic-advisory system, dedicated to the needs of the foundry industry. Multimedia techniques used in the system were selected to create a comprehensive capabilities of contact between user and computer system. The first part of the considerations apply to work in diagnostic mode, including identification of castings defects and determine the causes of their occurrence, the second part is a look at some of the features of the system implemented in a consultative mode, such as the integration of knowledge or technical and market expertise. Many illustrations was used to illustrate the various forms of contact with the user.

Multivariate regression models are often used for the purpose of prognosis. Parameters of such models are estimated on the basis of learning sets, where feature vectors (independent variables) are combined with values of response (target) variable. The values of response variable can be determined only with some uncertainty in some important applications. For example, in survival analysis, the values of response variable is often censored and can be represented as intervals. The interval regression approach has been proposed for designing prognostic tools in circumstances of such type of uncertainty. The possibility of using the convex and piecewise linear (CPL) functions in designing linear prognostic models on the basis of interval learning sets is examined in the paper.

This paper presented a finite element simulation model for the analysis of AISI D2 orthogonal cutting process using TiAIN coated inserts. Firstly, AISI D2 material constitutive model was built based on power law model, which was used in the FEM codes to describe the effect of strain, strain rate and temperature on the material flow stress. In modeling the chip formation, a damage model was employed to predict the chip separation. Then cutting edge radius and thickness of TiAIN coating of cutting tool were measured by SEM. Friction coefficients of cutting tool against AISI D2 steel were obtained by ball-on-plate friction tests on UMT-2 high speed tribometer. Finally, finite element simulations of AISI D2 orthogonal cutting processes were performed using Advantedge? software. The simulated results of cutting forces and chip morphology showed good agreement with the experimental results, which validated the reliability of the cutting process simulation method.

The objectives of the study were to use finite element computer modeling to investigate the behavior of Wisconsin W wide-flanged prestressed girder ends during and immediately following the strand detensioning process, and to identify solutions for controlling girder end cracking by reducing concrete tension strain or introducing sufficient reinforcement to keep concrete tension strains low and crack width limited.

In the crossroad between Artificial Intelligence and Digital Entertainment we find the technologies to create characters that are adaptable to new situations, unpredictable, fast learners, enabled with memory of past situations and a variety of consistent and convincing behaviour over time. According to recent studies in the fields of Neuroscience and Psychology, the ability to solve problems is not only related to the capability to manipulate symbols, but also to the ability to explore the environment and to engage into social interactions, which can be expressed as emotional phenomena. The results of these studies characterize the key role that personality and emotions play in the activities of perception, attention, planning, reasoning, creativity, learning, memory and decision making. When modules for handling personality and emotion are incorporated into an agent architecture, it is possible to build believable agents. In the present work, we introduce a computer architecture to build believable agents enabled with personality and emotion.

The dramatic growth of Internet and network technologies, etc leads to different perspectives of computing methodologies as well as changes of software business model. If the traditional business model for software is one-time payment for a license for one machine with unlimited use, the development of Internet and network technologies, etc makes it possible for users to pay on their consumption as they pay for water, gas and electricity. With advanced technology all computing and storing process can be centralized on the infrastructure of service providers. With this new model, users don't have to concern about deploying their infrastructure, security, etc which will be responsible by service providers. This new trend grows extremely fast in last couple years and attracts a lot of researches from scholars such as Grid Computing model, Client Server model and especially Cloud Computing model with its scalability. In this paper we do not analyze differences between these utility computing models and what model will be the main field in the future. Instead we present how to use computer networks as a mean of computing and simulation and how computer networks are considered as a solution to boost technology development. Two software applications through computer networks were developed and applied successfully in teaching and learning courses in Auburn University and Bradley University are presented in this paper. It is a typical example of enhanced interaction between human and CAD tools while computer networks play a role as a human system interface.

By analyzing data from a long-duration deployment of four wave- powered unmanned surface vehicles called Wave Gliders, an assessment of operating characteristics informs the potential utility of the Wave Glider in an undersea distributed network as a replacement for a moored communications gateway buoy. Specifically, the wave-powered propulsion system is analyzed to assess endurance, operability, and application in an underwater distributed network as the gateway node. The results of the study serve to identify the parameters for an experiment designed to test the Wave Glider as a station- keeping gateway node.
