On-line Professional Learning Communities: Increasing Teacher Learning and Productivity in Isolated Rural Communities Dora Salazar, Zenaida Aguirre-Muñoz, Kelly Fox, Lisa Nuanez-Lucas Pages: 1-7
ABSTRACT: On-line and distance professional learning communities provides
teachers with increased access and flexibility as well as the
combination of work and education. It also provides a more
learner-centered approach, enrichment and new ways of
interacting with teachers in isolated rural areas. For educational
administrators, on-line learning offers high quality and usually
cost-effective professional development for teachers. It allows
upgrading of skills, increased productivity and development of a
new learning culture. At the same time, it means sharing of costs,
of training time, increased portability of training, and the exchange
of creativity, information, and dialogue.
Empowering Learners to Choose the Difficulty Level of Problems Based on Their
Learning Needs Janet Mannheimer Zydney, Lori Diehl, Amy Grincewicz, Paul Jones, Ted S. Hasselbring Pages: 8-13
ABSTRACT: Research has found that increasing learner control offers several
benefits, including increased motivation, attitude, and learning.
The goal of the present study was to determine how prior math
achievement influences students’ selection of the difficulty level
of problems within Math Pursuits, a hypermedia learning
program. Math Pursuits was designed to help children
understand mathematics by discovering how it relates to the
world around them. The program presented each learner with an
adjustable level of challenge, along with the necessary
scaffolding to support success. The researchers hypothesized
that students with lower math skills would choose to start with a
lower difficultly level; whereas, students with higher math skills
would begin the program by choosing a question with a higher
level of difficulty. Results supported these hypotheses. This
research also examined the motivational framework guiding
students’ selection of problem difficulty.
Content Aware Burst Assembly – Supporting Telesurgery and Telemedicine in Optical Burst Switching Networks Henry Orosco, Lei Wang, Yuhua Chen Pages: 14-22
ABSTRACT: The emerging Telemedicine and Telesurgery technologies
allow patients to share medical experts remotely through
communication networks. However, network bandwidth,
network latency and jitter (variation of latency), are the
obstacles to the widespread use of this technology remotely.
Optical Burst Switching (OBS) networks greatly expand
network bandwidth in existing network infrastructure by
utilizing multiple DWDM channels within a single fiber,
enabling high bandwidth applications. However, the burst
assembly process in OBS networks introduces latency and
jitter, making it unsuitable for high bandwidth, latency
sensitive applications such as telesurgery and telemedicine. In
this paper, we propose a content aware burst assembly scheme
which dynamically adjusts the burst assembly parameters based
on the content being assembled. The proposed content aware
burst assembly minimizes the latency and jitter within a video
frame, as well as across the left-view and right-view frames for
3D vision generation. Simulation results have shown that the
proposed scheme can effectively reduce the latency and jitter
experienced by video streams, making OBS a promising
candidate for supporting telesurgery and telemedicine
applications.
Solving Two –Dimensional Diffusion Equations with Nonlocal Boundary Conditions by a Special Class of Padé Approximants Mohammad
Siddique Pages: 23-29
ABSTRACT: Parabolic partial differential equations with nonlocal boundary
conditions arise in modeling of a wide range of important
application areas such as chemical diffusion, thermoelasticity,
heat conduction process, control theory and medicine science.
In this paper, we present the implementation of positivity-
preserving Padé numerical schemes to the two-dimensional
diffusion equation with nonlocal time dependent boundary
condition. We successfully implemented these numerical
schemes for both Homogeneous and Inhomogeneous cases. The
numerical results show that these Padé approximation based
numerical schemes are quite accurate and easily implemented.
Integral Design workshops: organization, structure and testing Wim Zeiler, Perica Savanovic Pages: 30-41
ABSTRACT: The purpose of this paper is to achieve an
understanding of design activities in the context of
building design. The starting point is an overview
of design research and design methodology. From
the insights gained by this analysis of design in this
specific context, we present an ‘organization
structure and design’ workshop approach for
collaborative multi-discipline design management.
The workshops set-up, used to implement and to
test the approach, are presented as well as the
experiences of the participants. The project was
done in close cooperation with the professional
societies with in the Dutch building design field.
More than one hundred experienced professionals
participated in the workshops. The workshops have
become part of the permanent professional training
program Dutch architectural society.
Phase Retrieval Algorithm for Form Testing Metrology in Production Environment Stephan Stuerwald, Robert Schmitt Pages: 42-47
ABSTRACT: Form testing interferometry permits a fast, non-tactile and full-
field quantitative phase imaging of components in ultra precise
manufacturing. To reduce the influence of vibrations under
manufacturing conditions, it is most common to use the FT-
based spatial carrier phase measurement technique (SCPM)
which requires only a single interferogram recording. The
utilization of a generalized, relatively new spatial phase-shifting
method operating in the position space opens up prospects for
reduced phase noise and less reconstruction errors of the
calculated phase-map under production conditions. Therefore
this phase-shifting technique is investigated for applicability in
machine integrated interferometric form testing of optical lenses.
A characterization of the algorithm and a comparison with the
commonly used FT-based algorithm is performed. As a
reference, measurements are carried out with a coordinate
measuring machine with nanometre accuracy.
Development of Safe Taiwan Information System (SATIS) for Typhoon Early Warning in Taiwan Wen-Ray Su, Pai-Hui Hsu, Shang-Yu Wu, Feng-Tyan Lin, Hsueh-Cheng Chou Pages: 48-52
ABSTRACT: Due to the particular geographical location
and geological condition, Taiwan is constantly
attacked by typhoons, flood, landslides, debris flows,
and earthquakes. Those natural hazards had caused
huge loss of lives and properties. To reduce the
damages and losses caused by the natural hazards, an
integrated and complete decision support system for
decision makers is necessary. In this study, Safe
Taiwan information system (SATIS), which includes
two subsystems, response operation subsystem for
staff members and decision support subsystem for
commanders, is developed for preparedness and
response of typhoon hazards. It is based on the Web-
GIS framework that the disaster information can be
distributed via internet technology. When typhoon is
approaching, response operation subsystem is used by
National Science and Technology Center for Disaster
Reduction (NCDR) staffs to integrate real-time
monitoring information, hazard models and graphical
user interfaces to analyze and manage the disaster
information such as the current position and possible
path of typhoon, the spatial distribution of rainfalls,
and potential areas of flooding, landslides and debris
flows. The input data of this subsystem includes the
basic maps, the real-time information of typhoon and
rainfall issued by the Central Weather Bureau, the
real-time water information from the Water Resources
Agency, and the hazard maps indicating areas of
potential landslide, debris flow and flooding made by
NCDR herself to estimate endangered areas under the
current typhoon. There are four main modules
integrated into the subsystem including the rainfall
monitoring and forecasting, the estimation of potential
inundation areas, the estimation of potential landslide
and debris flows, and the management of disaster
information. The results of hazard risk analysis which
include potential rainfall distribution, inundation and
landslide risk areas, early warning messages, and total
suggestion over the next 24 hours are finally
demonstrated by decision support subsystem in the
National Emergency Operations Center (NEOC) and
help the commander to make the right decisions in
disaster preparedness and response phases. In the
future, SATIS will integrate social and economic
information into the assessment of natural hazard
vulnerability. It can help the commander to know the
high-risk areas and make the right decision.
| | The Simulation and Animation of Virtual Humans to Better Understand Ergonomic Conditions at Manual Workplaces Jürgen Rossmann, Christian Schlette Pages: 53-58
ABSTRACT: This article extends an approach to simulate and control anthro-
pomorphic kinematics as multiagent-systems. These "anthro-
pomorphic multiagent-systems" have originally been developed
to control coordinated multirobot systems in industrial applica-
tions, as well as to simulate humanoid robots. Here, we apply
the approach of the anthropomorphic multiagent-systems to
propose a "Virtual Human" - a model of human kinematics - to
analyze ergonomic conditions at manual workplaces. Ergonom-
ics provide a wide range of methods to evaluate human postures
and movements. By the simulation and animation of the Virtual
Human we develop examples of how results from the field of
ergonomics can help to consider the human factor during the
design and optimization phases of production lines.
Towards Optimal Transport Networks Erik P. Vargo, Rex K. Kincaid, Natalia Alexandrov Pages: 59-64
ABSTRACT: Our ultimate goal is to design transportation net-
works whose dynamic performance metrics (e.g. pas-
senger throughput, passenger delay, and insensitivity
to weather disturbances) are optimized. Here the fo-
cus is on optimizing static features of the network that
are known to directly affect the network dynamics.
First, we present simulation results which support a
connection between maximizing the first non-trivial
eigenvalue of a network’s Laplacian and superior air-
port network performance. Then, we explore the ef-
fectiveness of a tabu search heuristic for optimizing
this metric by comparing experimental results to the-
oretical upper bounds. We also consider generating
upper bounds on a network’s algebraic connectivity
via the solution of semidefinite programming (SDP)
relaxations. A modification of an existing subgraph
extraction algorithm is implemented to explore the
underlying regional structures in the U.S. airport net-
work, with the hope that the resulting localized struc-
tures can be optimized independently and reconnected
via a “backbone” network to achieve superior network
performance.
Vision System for Relative Motion Estimation from Optical Flow Sergey M. Sokolov, Andrey A. Boguslavsky, Felix A. Kuftin Pages: 65-70
ABSTRACT: For the recent years there was an increasing interest in different
methods of motion analysis based on visual data acquisition.
Vision systems, intended to obtain quantitative data regarding
motion in real time are especially in demand. This paper talks
about the vision systems that allow the receipt of information on
relative object motion in real time. It is shown, that the
algorithms solving a wide range of practical problems by
definition of relative movement can be generated on the basis of
the known algorithms of an optical flow calculation. One of the
system’s goals is the creation of economically efficient
intellectual sensor prototype in order to estimate relative objects
motion based on optic flow. The results of the experiments with
a prototype system model are shown.
Education and Project Management: The Introduction to IS course Dennis Bialaszewski, Marsha Bialaszewski Pages: 71-75
ABSTRACT: The Introductory literacy course has undergone many changes
over the last several years. Of course the content has changed
over time. However, the delivery of this course is also
changing. In this paper we present a delivery method that the
author(s) have employed for the last several years which
incorporates active learning, experiential learning and team
based approaches including virtual teams However, in today’s
global society, the incorporation of project management skills
and theory has also become a new and critical component of
the Information Literacy course.
Toll Roads Distribution in The United States Qing Zhu, Fengxiang Qiao, Lei Yu Pages: 76-79
ABSTRACT: A toll road (or toll way, turnpike, pike, or toll highway) is a
roadway where drivers pay tolls (i.e. fees) for the use. In
addition to fuel tax or general tax funds, toll collection is an
alternative source of revenue generation [1]. Decision makings
of a toll road may depend on a lot of factors such as regional
economics, local and national policies, and even population
density. It is an interesting phenomenon that there are more toll
roads in the eastern part of The United States than in the
western part. However, there is no discussion and analysis
about this unbalanced distribution, not to say to explore the
reasons behind. This paper aims to find out if it is really true
that there are more toll roads in the eastern part of the U.S. than
in the western part, and the reasons for national toll roads
distribution through different analytical angles. The result can
help in the perfection of national and state roadway network and
toll roads designs in U.S., which will also be beneficial to the
development and improvement of toll roads and modern
highway system in developing countries and other developed
countries.
Challenges in Capitalizing Knowledge in Innovative Product Design Process Inès Saad, Michel Grundstein, Camille Rosenthal-Sabroux Pages: 80-85
ABSTRACT: Capitalizing on company’s knowledge is increasingly being recognized in a private organizations environment since managing knowledge productivity is considered a source of competitive advantage. In this paper we present a generalization of GAMETH framework, that play an important role in identifying crucial knowledge used and created in innovative product design process. Thus, we have developed a method based on three phases. In the first phase, we have used GAMETH to identify the set of “reference knowledge”. During the second phase, decision rules are inferred, through rough sets theory, from decision assignments provided by the decision maker(s). In the third phase, a multicriteria classification of “potential crucial knowledge” is performed on the basis of the decision rules that have been collectively identified by the decision maker(s).
