In late August through mid-December 2010, the Census Bureau conducted a field test of new and revised content in the 2010 American Community Survey (ACS) Content Test. The results of that testing will determine the content to be incorporated into production ACS starting in 2013. Computer ownership and Internet subscription questions need to be added into the American Community Survey due to legislative changes. The Broadband Data Improvement Act requires that the Secretary of Commerce, in consultation with the Federal Communications Commission, expand the ACS to elicit information from residential households to determine whether they own or use computers at their address, whether they subscribe to an Internet service and, if so, whether they subscribe to dial-up or broadband Internet service at that address. The goal of this project is to evaluate the two versions of computer ownership and Internet subscription questions in the 2010 ACS Content Test to help determine which one will ultimately go into ACS production starting in 2013.

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.

The paper presents a prototype of a system which can be used as a therapeutic and educational tool for children with developmental problems. Natural body movements and gestures are used in the system to interact with virtual objects displayed on the screen. Nowadays such systems can be built with the use of widely available free software tools for both graphical and vision applications. Such tools are also shortly presented in the paper.

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 work, we propose a model of students' examination data which can contain timestamp and handwriting information using a tablet computer. Stored data is consumed by students' achievement recording software so that both teachers and students can trace their records at any time. The handwriting data in this work can be expressed as XML description so that other applications can use the data easily. The scope of this work is limited to store students' examination information so that it is recommended to be combined with students' profile or other valuable data. Inside the data, this work treats the examination information, question information, students' response time of each question, and moreover, students' behavioral factors including page navigation, removal and writing activities. With the students' behavioral data, a visualization software can give user to suppose the student's activity easily and vividly. In this work, we describes an example of visualization software which allows user to review recorded secondary students' mathematics examination. Not only score-based assessment, our work may contribute to improve student's assessment and feedback with various educational insights.

Interactive drama and storytelling applications have become major issues in video games development. Prior research in interactive storytelling identified that adding narrative in computer games is a challenging task because: (ⅰ) it may restrict player interactivity, (ⅱ) narrative causality/control, (ⅲ) the duality between characters and plot, and (ⅳ) the trade-off between narrative progression and user interaction. This chapter attempts to solve these problems by proposing an integrated framework for deeply combining interactivity and narrative in computer games workflow. It presents state-of-the-art results with respect to interactive drama and Petri nets (PN), and highlights some petri-net-based workflow tools for game design and game rules principles. The idea is to compose the game rules in the game's workflow environment by different triggers and effects; and separates the rules of the game environment into two parts: controllable and non-controllable rules. The main contribution of this chapter is to show how workflow management concepts can be jointly utilized with Petri nets (PN) for modeling game systems and game workflow control. Evaluation and performance results supported by some case study called "crazy ball 2" are also demonstrated. "Crazy ball 2" is a platform-type genre, much like the worldwide-known game Mario and the Konami's Castlevania series.

The TSPROC (Time Series PROCessor) computer soft-ware uses a simple scripting language to process and analyze time series. It was developed primarily to assist in the calibra-tion of environmental models. The software is designed to perform calculations on time-series data commonly associated with surface-water models, including calculation of flow vol-umes, transformation by means of basic arithmetic operations, and generation of seasonal and annual statistics and hydro-logic indices. TSPROC can also be used to generate some of the key input files required to perform parameter optimization by means of the PEST (Parameter ESTimation) computer soft-ware. Through the use of TSPROC, the objective function for use in the model-calibration process can be focused on specific components of a hydrograph.
