Concept Mapping as a Tool for Enhancing Self-Paced Learning in a Distance Scenario

Researchers have determined that concept maps serve as effective tools in the traditional science classroom. The purpose of this experimental study was to investigate concept mapping as a tool for student knowledge acquisition in 10 th grade science for students in distance learning situations. Research questions were designed to investigate the influence of concept mapping on rate and quality of student knowledge acquisition and retention. This study was a pretest-posttest 2-group comparison study, constructivist in nature and based on the theory of cognitive learning. Participants included 36 students in the 10 th grade at an inner-city school in the United States. Control and treatment groups participated in completing pre and posttesting to establish standards for initial understanding and knowledge acquired. Pretest scores were used in a 2-tailed t test to establish equivalence between groups at the beginning of the study. ANOVA was used with test gains to determine differences between treatment and control groups. Cronbach’s alpha was conducted to test for concept map interrater reliability. A 2-tailed t test for matched groups was used with concept map scores and treatment group test gains to determine any relationship. No statistically significant relationship between the use of concept maps and distance learning was found. Recommendations for future research include a wider age range for participants and investigations of academic areas such as reading, writing, mathematics, and language acquisition, native and foreign. Implications for positive social change include research with altered parameters to identify an existing tool that may be used by students in the traditional classroom as well as in distancelearning scenarios.

Teaching Research Data Management: An Undergraduate/Graduate Curriculum

With funding from the Institute of Museum and Library Services, the Libraries of the University of Massachusetts Medical School and Worcester Polytechnic Institute collaborated on a plan to expand the scope of science library practices and promote among medical, graduate, and undergraduate science students the preservation of scientific data in relevant repositories and archives. This paper outlines curriculum frameworks and learning needs for research data management instruction that can be delivered through a variety of methods. Individual modules are based on faculty and student interviews, as well as a comprehensive literature review. Background Student research projects are part of the core educational missions at both the University of Massachusetts Medical School (UMMS) and Worcester Polytechnic Institute (WPI). Both institutions struggle to manage massive data sets generated by students. The need to manage large data sets is well documented (Carlson 2006, Doctorow 2008, National Science Board 2005), and librarians are working to apply their skills in information management to this issue. The two libraries came together, with funding from the Institute of Museum and Library Services and the National Library of Medicine, to develop the preliminary tools for a full data management curriculum of open access educational tutorials that can be woven into any science, health science, or engineering curriculum. This article outlines the development of the curriculum, a curriculum framework, and competencies for instructing students on how to incorporate data management into the research process. Curriculum Development An education committee with representatives from the library, information technology, and the faculty from each campus was assembled to oversee the development of the curriculum.

Optimal control and forecasting of complex dynamical systems

This important book reviews applications of optimization and optimal control theory to modern problems in physics, nano-science and finance. The theory presented here can be efficiently applied to various problems, such as the determination of the optimal shape of a laser pulse to induce certain excitations in quantum systems, the optimal design of nanostructured materials and devices, or the control of chaotic systems and minimization of the forecast error for a given forecasting model (for example, artificial neural networks). Starting from a brief review of the history of variational calculus, the book discusses optimal control theory and global optimization using modern numerical techniques. Key elements of chaos theory and basics of fractional derivatives, which are useful in control and forecast of complex dynamical systems, are presented. The coverage includes several interdisciplinary problems to demonstrate the efficiency of the presented algorithms, and different methods of forecasting complex dynamics are discussed.
FACIAL FEATURE TRACKING AND POSE ESTIMATION IN VIDEO SEQUENCES DUE TO THE PARTIAL SYMMETRIES OF FACES BY FACTORIAL CODING OF THE LOW-DIMENSIONAL ENTROPY MANIFOLDS

In a number of practical scenarios, such as video conferencing and visual humankomputer interaction, objects that belong to a well defined class are segmented, normalized, and encoded, after which they are stored and/or transmitted, and subsequently reconstructed. The Karhunen-Lokve Transform (KLT) optimally concentrates the signal power in a relatively small number of uncorrelated coefficients. Nevertheless, i t implicitly ~ S S I J ~ C S a multidimensional Gaussian probability model, which is typically not correct. Here we show that, in the context of video scqiicnces of human heads, the segmentation and normalization steps result in partial symmetries which force the KLT coefficients to lie close to low-dimensional manifolds in suitably chosen high-dimensional KLT subspaces. We show how this fact can be used to track the faces robustly, and to estimate their pose. We use vector quanti7,ation to discover those manifolds, and to build a factorial code that has a substantially lower dimensionality than KLT.
System for Collision Detection Between Deformable Models Built on Axis Aligned Bounding Boxes and GPU Based Culling

A SYSTEM FOR COLLISION DETECTION BETWEEN DEFORMABLE MODELS BUILT ON AXIS ALIGNED BOUNDING BOXES AND GPU BASED CULLING David O. Tuft Department of Computer Science Master of Science Collision detection between deforming models is a difficult problem for collision detection systems to handle. This problem is even more difficult when deformations are unconstrained, objects are in close proximity to one another, and when the entity count is high. We propose a method to perform collision detection between multiple deforming objects with unconstrained deformations that will give good results in close proximities. Currently no systems exist that achieve good performance on both unconstrained triangle level deformations and deformations that preserve edge connectivity. We propose a new system built as a combination of Graphics Processing Unit (GPU) based culling and Axis Aligned Bounding Box (AABB) based culling. Techniques for performing hierarchy-less GPU-based culling are given. We then discuss how and when to switch between GPU-based culling and AABB based techniques.
Encyclopaedic question answering

Open-domain question answering (QA) is an established NLP task which enables users to search for speciVc pieces of information in large collections of texts. Instead of using keyword-based queries and a standard information retrieval engine, QA systems allow the use of natural language questions and return the exact answer (or a list of plausible answers) with supporting snippets of text. In the past decade, open-domain QA research has been dominated by evaluation fora such as TREC and CLEF, where shallow techniques relying on information redundancy have achieved very good performance. However, this performance is generally limited to simple factoid and deVnition questions because the answer is usually explicitly present in the document collection. Current approaches are much less successful in Vnding implicit answers and are diXcult to adapt to more complex question types which are likely to be posed by users. In order to advance the Veld of QA, this thesis proposes a shift in focus from simple factoid questions to encyclopaedic questions: list questions composed of several constraints. These questions have more than one correct answer which usually cannot be extracted from one small snippet of text. To correctly interpret the question, systems need to combine classic knowledge-based approaches with advanced NLP techniques. To Vnd and extract answers, systems need to aggregate atomic facts from heterogeneous sources as opposed to simply relying on keyword-based similarity. Encyclopaedic questions promote QA systems which use basic reasoning, making them more robust and easier to extend with new types of constraints and new types of questions. A novel semantic architecture is proposed which represents a paradigm shift in open-domain QA system design, using semantic concepts and knowledge representation instead of words and information retrieval. The architecture consists of two phases, analysis – responsible for interpreting questions and Vnding answers, and feedback – responsible for interacting with the user. This architecture provides the basis for EQUAL, a semantic QA system developed as part of the thesis, which uses Wikipedia as a source of world knowledge and

Jitter reduction circuits to reduce the bit -error rate of high-speed serializer-deserializer (SERDES) circuits

OF THE DISSERTATION Jitter Reduction Circuits to Reduce the Bit-Error Rate of High-Speed Serializer-Deserializer (SERDES) Circuits by Hari Vijay Venkatanarayanan Dissertation Director: Prof. Michael L. Bushnell A new jitter reduction technique is proposed for reducing the timing jitter in a serializer-deserializer (SERDES) circuit. The technique involves transmit and receive side jitter reducer circuits made of only 14 and 20 transistors, respectively. They reduce the jitter in the clock generated by the phase-locked-loop (PLL) at the transmit side, and the jitter between the recovered clock and the serial data at the receive side. The jitter reducers are designed using 70nm Berkeley Predictive process models and tested with various types of input jitter. In the case of the transmit side jitter reducer, the jitter is reduced, on average, by 62.24%. The performance of the jitter reducer is compared with the adaptive PLL technique proposed by Xia et al. [39] in terms of the peak-to-peak jitter reduction. The peak-to-peak jitter is reduced, on average, by 45.51% using the transmit side jitter reducer. For the receive side jitter reducer, the jitter is reduced, on average, by 35.88%. The SERDES circuit is then tested for its jitter performance under three conditions: (1) no jitter reducers are present, (2) the receive side jitter reducer is present and (3) both transmit and receive side jitter reducers are present.

Practical implementation of distributed optimization algorithms for cross-layer design: data link and physical layer

A surge arrester includes a stack of varistor blocks (10), for example of zinc oxide, arranged between two end electrodes (11, 12) in an elongated insulating casing (23) of polymeric material, for example silicone rubber. The varistor blocks and the electrodes are axially surrounded by compression loops (14-17) of insulating material for providing the necessary contact pressure between the different elements (10, 11, 12) in the varistor stack. The varistor stack (10) and the compression loops are radially surrounded by a bursting-preventive bandage (21) of insulating material with openings (22) for pressure relief in case of internal short circuit in the surge arrester.

Security with Noisy Data: Private Biometrics, Secure Key Storage and Anti-Counterfeiting

Over the past decades a large range of security primitives has been developed to protect digital information. These primitives have solved many traditional security problems and achieved a high level of sophistication. Their security properties are well understood. An intrinsic property, vital for secure operation, is that they are extremely sensitive to small variations in their input.
Evolutionary GPGPU compilers and execution time measurements

The problems of measurements of the execution time for CUDA kernels are considered in this paper. A few estimators are compared for different execution times. The proper measurements are important for code optimization using evolutionary compilers. The best estimator for fast time kernels (ms) is the minimal value estimator. The single run value is applicable for long time kernels (seconds). The disturbances of measurements are also related to the time between kernel runs, which is an unexpected result.
Interactive Techniques Between Collaborative Handheld Devices and Wall Displays

Interactive Techniques Between Collaborative Handheld Devices and Wall Displays Daniel L. Schulte Department of Computer Science, BYU Master of Science Handheld device users want to work collaboratively on large wall-sized displays with other handheld device users. However, no software frameworks exist to support this type of collaborative activity. This thesis introduces a collaborative application framework that allows users to collaborate with each other across handheld devices and large wall displays. The framework is comprised of a data storage system and a set of generic interactive techniques that can be utilized by applications. The data synchronization system allows data to be synchronized across multiple handheld devices and wall displays. The interactive techniques enable users to create data items and to form relationships between those data items. The framework is evaluated by creating two sample applications and by conducting a set of user study interactive tasks. The data recorded from these evaluations shows that the framework is easy to extend, and that with minimal training, the generic interactive techniques are easy to learn and effective.
An FPGA Implementation of a High Performance AER Packet Network

This thesis presents a design to route the spikes in a cognitive computing project called Systems of Neuromorphic Adaptive Plastic Scalable Electronics (SyNAPSE). SyNAPSE is a DARPA-funded program to develop electronic neuromorphic machine technology that scales to biological levels. The basic computational block in the SyNAPSE system is the asynchronous spike processor (ASP) chip. This analog core contains the neurons and synapses in a neural fabric and performs the neural and synaptic computations.An ASP takes asynchronous pulses (spikes) as inputs and after some small delay produces asynchronous pulses as outputs.The ASP chips are organized in a nxn (where n ∼= 10) 2-dimensional grid with a dedicated node for each chip. This interconnected network is calledDigital Fabric(DF) and the node is called Digital Fabric Node (DFN). The DF is a packet network that routes pulse (AER Address event representation) packets between ASP’s. This thesis also presents a technique for design implementation on a FPGA, performance testing of the network and validation of the network using various tools.

Fotogrametría de objeto cercano por métodos simples. Aplicación al estudio de las construcciones agroindustriales tradicionales

El concepto de patrimonio se ha ido ampliando de forma paulatina abarcando cada dia nuevos ambitos. Desde la idea tradicional de monumento hasta el concepto actual de patrimonio cultural, se ha generado en la sociedad una preocupacion sobres su conservacion, mantenimiento y transmision. Una de las corrientes de sensibilziacion mas recientes se centra en la proteccion de las intervenciones del hombre, que ha modelado el entorno natural a traves de usos agricolas y formas tradicionales de explotacion de los recursos naturales, conformando lo que se conoce como paisajes culturales. Estos entornos transformados por la actividad humana son testimonios esplendidos de la adaptacion del hombre y sus formas de vida al medio en que ha vivido. En este trabajo se analiza la problematica que envuelve un tipo de construccion pertenecientes a este ambito, la denominada construccion agroindustrial tradicional. Se realiza un analisis de los problemas de abandono, alteracion y desaparicion que dominan en la actualidad a estas construcciones en Galicia, localizadas siempre en el medio rural. Se proponen soluciones de cara a a paliar en ciertas medida la perdida patrimonial que se esta produciendo, mediante la utilizacion de tecnicas que permiten su registro y documentacion antes de que desaparezcan definitivamente. Se estudian las metodologias clasicas empleadas en la toma de datos para la documentacion arquitectonica (metodos manuales convencionales, topograficos, fotogrametricos, etc), analizando diferentes aspectos con vista a la eleccion del mas apropiado teniendo en cuenta los condicionantes establecidos. La tecnica que se propone se enmarca en la denominada fotogrametria de objeto cercano por metodos simples. Se analiza su uso como metodo de facil aplicacion y coste reducido, con el fin de poder emplearlo sin necesidad de una formacion especializada, facilitando su universalizacion mediante un aumento de l
