This paper aims at contributing to a better understanding of essential concepts of visual design aided by computer. Towards this end, we first present an ontology of conceptual visual design. Then, we define particular components of the formal model paying attention to the role of different kinds of classification during the design process. Moreover, we present two types of logic models used in computer tools supporting the design process. Finally, a formal model of computer-aided visual design is defined. The model is illustrated on examples of designing floor layouts based on a graph-based data structure gathering information for design knowledge and describing two categories of thinking during design process.

Multibody system (MBS) computer codes currently being used are based on three-decade old technology that is failing to respond to new modeling challenges. Modern and complex ground vehicle models, for example, include significant details that cannot be captured using existing MBS software technology. This paper discusses a new Department of Defense (DoD) initiative focused on the development of new generation of MBS computer codes that have capabilities and features that are not provided by existing MBS software technology. New applications require accurate continuum mechanics based vehicle/soil interaction models, belt and chain drive models, efficient and accurate continuum based tire models, cable models used in rescue missions, models that accurately capture large deformations due to thermal and excessive loads, more accurate bio-mechanics models for ligaments, muscles, and soft tissues (LMST), etc. Addressing these modeling and virtual prototyping challenges is necessary in order for industries and federal laboratories to have a new generation of MBS software that will serve their mission. The development of such a new software technology will require a successful integration of computational geometry (CG), FE, and MBS algorithms. A fundamentally different FE approach is required for the new integration of CG, large displacement FE, and MBS algorithm. This will be accomplished in the DoD initiative using the nonlinear FE absolute nodal coordinate formulation (ANCF) that has many desirable features. This paper discusses the feasibility of developing such a new software technology that is required for accurate virtual prototyping of vehicles, machines, and equipment.

Optical imaging systems have traditionally been analyzed using well-established approximations such as ray-based geometrical optics (Born & Wolf, 1999) and scalar Fourier theory (Goodman, 1996). However, there has recently been increased interest in applying the rigorous framework of Maxwell's-equations-based electromagnetic theory and numerical modeling to the analysis of optical imaging systems. The availability of more powerful computer hardware and more efficient computational algorithms has obviously contributed to this interest. Although the basic principles of light scattering encoded in Maxwell's equations had been around for decades, the widespread application of these principles to the complete modeling of an optical imaging system had to wait until the 1990s, at which time the personal computers were getting powerful enough to process megabytes of data in their memory.

In this paper, the idea of Computer-Aided Translation is first introduced and a modern approach to CAT is then presented. Next, we provide a more detailed description of one of the state-of-art CAT systems - memoQ. Then, the author's approach to the idea - the Anubis system - is described and evaluated. While Anubis is comparable to memoQ in terms of the precision of provided translation memory matches, it outperforms memoQ when it comes to the speed of searching the translation memory. In the experiments carried out, Anubis turned out to be over 430faster than memoQ. The result was achieved thanks to the author's algorithm of minimizing the size of translation memory index, so it can be stored in computer's RAM memory. The paper is divided in two parts: the first describes the field of CAT, where the Anubis system can be applied. The second gives a detailed description of Anubis itself, proving its potential usefulness.

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.

It is demonstrated that spectral characteristics of steady-state visual evoked potentials (SSVEPs) in a brain-computer interface (SSVEP-based BCI) depend significantly on the stimulus parameters, such as color and frequency of its flashing light. We postulate these dependencies can be used to improve the BCI performance - by proper design, configuration and adjustment of the visual stimulator. Preliminary results of conducted experiments show also that SSVEP characteristics are strongly affected by subjects biodiversity.

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 Simulation Interoperability Standards Organization (SISO) Smackdown is a two-year old annual event held at the 2012 Spring Simulation Interoperability Workshop (SIW). A primary objective of the Smackdown event is to provide college students with hands-on experience in developing distributed simulations using High Level Architecture (HLA). Participating for the second time, the University of Alabama in Huntsville (UAHuntsville) deployed four federates, two federates simulated a communications server and a lunar communications satellite with a radio. The other two federates generated 3D computer graphics displays for the communication satellite constellation and for the surface based lunar resupply mission. Using the Light-Weight Java Graphics Library, the satellite display federate presented a lunar-texture mapped sphere of the moon and four Telemetry Data Relay Satellites (TDRS), which received object attributes from the lunar communications satellite federate to drive their motion. The surface mission display federate was an enhanced version of the federate developed by ForwardSim, Inc. for the 2011 Smackdown simulation. Enhancements included a dead-reckoning algorithm and a visual indication of which communication satellite was in line of sight of Hadley Rille. This paper concentrates on these two federates by describing the functions, algorithms, HLA object attributes received from other federates, development experiences and recommendations for future, participating Smackdown teams.

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.
