Open education videos in the classroom: exploring the opportunities and barriers to the use of YouTube in teaching introductory sociology

The use of open education resources has become more commonplace in classroom teaching and this has been an observable and growing trend. The accessibility of the same materials further reinforces the change in roles of the teacher, from gatekeeper of knowledge to learning facilitator. Our research question is that if a student has free and easy access to the same materials that are being used to teach them in class, how does this affect their perceptions when they are presented with this material in the classroom environment? What are their perceptions regarding the perceived value for money, efficacy and authority of the material? This research specifically investigated the use of open education videos in the classroom environment and their incorporation into an associated space in the virtual learning environment. The research questions of this investigation surrounded the practical, technical and pedagogical issues that arise from the incorporation of these resources within class and online course materials as well as exploring student perceptions about the use of this material in the class and online. Keywords: YouTube; online video; open educational resources
Syllable as a unit of speech recognition

Basic problems involved in automatic recognition of continuous speech are discussed with reference to the recently developed template matching technique using dynamic programming. Irregularities in phonetic manifestations of phonemes are discussed and it is argued that the syllable, phonologically redefined, will serve as the effective minimal unit in the time domain. English syllable structures are discussed from this point of view using the notions of "syllable features" and "vowel affinity. "
A Study On Improving Information Processing Abilities Based On PBL

This study examined an instruction method for the improvement of information processing abilities in elementary school students. Current elementary students are required to develop information processing abilities to create new knowledge for this digital age. There is, however, a shortage of instruction strategies for these information processing abilities. This research proposes a method for teaching information processing abilities based on a problem-based learning model, and was tested with elementary students. The students developed an improved ability to create new knowledge and to present relationships with information through the process of problem solving. This study performed experimental research by comparing pre- and post-tests with twenty-three fifth grade elementary students over the course of eight months. This study produced a remarkable improvement in information selection, information reliability, information classification, information analysis, information comparison, and information internalization. This study presents an improved methodology for the teaching of information processing abilities.
New iterative construction approach to routing with compacted area

The new iterative construction approach presented consists of three algorithms, namely, channel expansion routing, track assignment, and module location refinement. These algorithms, contrary to the conventional methods implemented with a sequence of tools separately, are linked with a common data structure which guarantees a maximal compatibility. With an initial nonoverlapping placement as input, the iterative construction approach generates a final layout with a more compacted area than the layout result from the one-dimensional compactor or some of two-dimensional compactors. Several layout examples in the literature are tested to show the effectiveness of the approach.
A high data rate universal lattice decoder on FPGA

This paper presents the architecture design of a high data rate universal lattice decoder for MIMO channels on FPGA platform. A phost strategy based lattice decoding algorithm is modified in this paper to reduce the complexity of the closest lattice point search. The data dependency of the improved algorithm is examined and a parallel and pipeline architecture is developed with the iterative decoding function on FPGA and the division intensive channel matrix preprocessing on DSP. Simulation results demonstrate that the improved lattice decoding algorithm provides better bit error rate and less iteration number compared with the original algorithm. The system prototype of the decoder shows that it supports data rate up to 7Mbit/s on a Virtex2-1000 FPGA, which is about 8 times faster than the original algorithm on FPGA platform and two-orders of magnitude better than its implementation on a DSP platform.
Cluster Head Selection Based On GeneticAlgorithm Using AHYMN Approaches inWSN

Wireless sensor networks (WSNs) are composed of number of sensor nodes in order to detect and transmit Information from its surrounding environment. The sensor nodes have limited computation capability, limited power and small memory size. In these networks, sensor nodes are dependent on low power batteries to provide their energy. As energy is a challenging issue in these networks, clustering models are used to overcome this problem. Genetic algorithms is used to select the cluster heads of networks. We consider the Routing is primary parameter for improving the life time of network. We propose Advance Hybrid Multihop Routing Network (AHYMN) approaches for implementation process. Selection of Cluster Head is based on Energy level in sensor node. We implemented the HYMN approaches with Genetic algorithm for aggregation the data in sensor network.

The multiple-access power spectral density (PSD) under realistic multipath channels extracted from experimental measurements, for both time-hopping pulse position and direct-sequence antipodal data modulations, is analytically derived and closed form solutions are given. Using a proper pulse shape compatible with the FCC spectral mask, examples of PSDs are given. The magnitude of PSD fluctuations in realistic environments is investigated and compared with line of sight measurements in an anechoic chamber, which may be used for FCC compliance tests.
Gerrymanders and Gerrygons: Microcomputer-Assisted Spatial Analytic Approaches to Vote Dilution Detection

When the Supreme Court made one person, one vote, the law of the land, the art of gerrymandering enjoyed a renaissance. The simultaneous advent of computers turned an old art into a new technology; yet the same technology, guided by an understanding of the complicated legal, historical, statistical, technical, methodological, and normative issues, may be employed to detect gerrymanders. Here we discuss the capabilities and limitations of common software and hardware in gerrymander construction and detection, and present the framework of a general strategy for using computers in the field of apportionment. Keywords: artificial intelligence, BASIC, gerrymander, malapportionment, mapping, PROLOG vote dilution, microcomputers.
Real-time implementation of large-size image restoration with edge-preserving

Up to now, there are a large number of image restoration algorithms developed and implemented on power-efficient hardware platforms. In this paper a fast restoration approach based on edge-preserving is proposed and ported on a multi- DSP platform. Firstly, classical Wiener filter is optimized and the blurred image is decomposed into two independent parts in frequency domain: a shift-invariant part and a shift-variant part. Then the result is obtained by combining the two parts. Secondly, parallel processing is adopted for the large volumes of data and the complex algorithms commonly encountered. The algorithm mentioned above is realized on a parallel system with 4 DSPs because one DSP can not afford such large amounts of data. In order to make full use of processors and memory, the timing and throughput is designed carefully to guarantee the data processed in a pipeline manner. In a word, experiments show the algorithm has higher performance than other methods with the same computational complexity and can achieve real-time processing.
Terrain level of detail in first person-ground perspective simulations

Abstract : The Army Game Project at the Naval Postgraduate School is utilizing Epic's Unreal game engine to create a realistic first person infantry simulation. The project involves both indoor and outdoor spaces, including terrain datasets larger than normally supported by the Epic engine. While there bas been extensive research relating to terrain rendering algorithms, they are unsuitable for this system due to hardware requirements, task limitation, or inefficient memory management. These limitations can be addressed by modifying the original terrain algorithm to include multiple levels of detail for complex terrain. This method raises new issues with projected textures, transparent textures, and multi-resolution rendering; therefore the implementation technique includes resolution for these concerns as well. The Epic world editor was also modified to enable world designers to control of these levels of detail. Performance tests have shown flat this terrain level of detail system significantly improves display times, thereby allowing greater terrain complexity while maintaining interactive frame rates. Rendering times in environments with small terrains improved almost 40%, while large complex terrain environments (sq km at 1 m resolution) fared even better.
The Second Language Curriculum: A decision-making framework for the coherent language curriculum

Introduction In this introductory paper, I have three major aims: first to provide a framework for discussing the language curriculum; second to define the notion of a ‘coherent’ language curriculum, the theme of this book as well as the title of this paper; and third to show how the other papers in this volume and the particular aspects of development they focus upon relate to the curriculum process as a whole. The word ‘curriculum’ is defined here in its broadest sense, to include all the relevant decision making processes of all the participants. The products of these decision making processes generally exist in some concrete form and can be observed and described: for example policy documents, syllabuses, teacher-training programmes, teaching materials and resources, and teaching and learning acts. The processes themselves are usually more difficult to identify and analyse. They involve such questions as: Who is supposed to make the decisions and who actually does? How are these people selected and what qualifications do they have? What are their terms of reference? What resources in time, money, information and expertise are available to them? etc. Other ‘process’ factors such as prejudice, preconception, ambition or laziness are even harder to examine, but may be no less influential in their effects. The framework consists of three sets of constraints on curriculum decision making. The first is policy. A curriculum which appears in all other respects to be successful, but which fails to achieve its aims, is hard to justify however much the participants may have benefited from their experience in other ways, for example socially or financially.
An improved push-pull Class-E RF tuned power amplifier with low maximum transistor current

This paper proposes an improved push-pull Class-E power amplifier with low maximum transistor current, which is a critical parameter for power amplifiers in low voltage design. Moreover, from its push-pull configuration, low harmonic distortion and large optimum load are achieved. These improved performances are confirmed by theoretical analysis and HSPICE simulation. The proposed design is suitable for the wireless RF transceiver in low voltage design.
Web Search Engines: Mining Right Information

A Web Search Engine maintains and catalogs the content of Web pages in order to make them easier to find and browse. There are many Search Engines which are similar, differentiates from the other by the methods for scouring, storing, and retrieving information from the Web. Usually Search Engines search through Web pages for specified keywords, in response they return a list of containing specified keywords documents. After finding the list of specified keywords documents, list is sorted by relevance criteria which try to put at the very first positions the documents that best match the user’s query. The usefulness of a search engine to most people is based on the relevance of results it retrieves from the web. This paper tries to address some issues regarding some of the major challenges faced by Search Engines, since the size of the Web is rapidly growing.
Cryptographic classification of quasigroups of order 4

Edon80 is a stream cipher design that had advanced to the third and last phase of the eSTREAM project. The core of the cipher consists quasigroup string e-transformations and it employs four quasigroups of order 4. The employed quasigroups have influence on the period of the key-stream. There are 576 quasigroups of order 4 in total which have the different period factors. In this paper, we discuss a cryptographic classification of quasigroups, and give a complete classification for the 576 quasigroups of order 4 according to the period factors. Keywords-Edon80; Latin square; period factor
Bridging the generation gap between text planning and linguistic realization

Text planning is traditionally done as a separate process, independent of linguistic realization. However, I show in this paper that it is essential for a text planner to know the linguistic consequences of its actions. The choice of how to realize an element affects how much information is conveyed (e.g., “Floyd arrived safely in Boston” vs. “Floyd landed safely at Logan”) and what other information can be added (e.g., “Peter was deciding for an hour” vs. *“Peter made a decision for an hour”). The choice of realization also affects how the relative salience of the elements being expressed will be perceived (e.g., “The green car is in the garage” vs. “The car in the garage is green”). I have defined an intermediate level of representation for text planning, called the Text Structure. It is an abstract linguistic level that reflects germane linguistic constraints while abstracting away from syntactic detail. This representation allows the text planner to have greater control over the decisions, so that it can take advantage of the expressiveness of language to convey subtleties of meaning. More importantly, the Text Structure allows the generation process overall to be incremental, since it ensures that the text plan being composed will always be expressible in the language.
A kinematic data gathering system to assess human motion in zero-g

Research was conducted to assess the feasibility of utilizing one-dimensional accelerometers mounted in an orthogonal arrangement to measure astronaut's motion in zero-gravity environments. The initial investigation was centered on determining optimal positions, orientations, and response of the accelerometer device. Various types of accelerometers were tested to determine the most suitable device for the measurement of low-frequency human motion. A system is described that eliminates the shortcomings of video-based systems while providing a real-time graphical representation of the motion. <<ETX>>

Avatars' Informational Preferences in a Virtual World

There is a growing interest among educators in exploring multi- user-virtual environments (MUVEs), such as Second Life, as platforms for distance learning and other applications. Additionally, such virtual environments provide rich opportunities for constructivist approaches to teaching and learning. Yet, the notion that virtual worlds also provide an opportunity for writing instructors to teach about multimodal texts and new media literacies is an area that has received less attention. This study examined the informational preferences of avatars (students) who were members of a class that met online in the virtual world of Second Life. Specifically, the purpose was to assess avatars' informational preferences from among three different media: print articles, machinima, and direct exploration within Second Life while enrolled in a course studying the virtual world of Second Life. Study found that avatars expressed a greater preference for information gathered from machinima and information gathered first-hand from Second Life than print-based information, although their subsequent discussions about the information varied in specificity, depending on the medium they were referencing.
Research on BSP Algorithm of Construction of Large-Scale 3D Point Model

For the construction of large-scale surface features 3D point model, a large number of point cloud data processing calculations is needed. Previous model construction calculation was treated non-parallel manner successively and mostly with one by one point cloud. This data processing method is complex, low efficiency and requires vast computing resource. Accordance with the BSP parallel computing ideas, we design a point cloud data modeling algorithm based on BSP and build a Hama parallel computing cluster consisted of ordinary PCs. The results indicate that, large-scale 3D point model BSP construction algorithm can improve the efficiency of modeling calculations and reduce computing resources requirements for processing construction computing.

A new technique to reduce line-current harmonics generated by a three-phase bridge rectifier

Three-phase bridge rectifiers are widely used in industry to interface DC loads to the electric utility because of their low ripple content output and high power-handling capability. The nonlinear nature of the diode type switching devices causes significant line-current harmonics resulting in increased distortion, malfunction of sensitive electronic equipment, increased losses, and contributes to inefficient use of electric energy. This paper describes a new approach to reduce those line-current harmonics generated by a three-phase diode rectifier type utility interface. The proposed approach consists of a novel interconnection of a delta-zig zag transformer between the AC and DC sides of the diode rectifier topology. This transformer connection in combination with the conduction intervals of each diode generates automatically a circulating third harmonic current between the AC and DC side of the rectifier bridge. Voltage and current analysis and simulation using the Electro-Magnetic Transients Program (EMTP) showed that the generated circulating current may drastically reduce the line current harmonics of the AC side and smooth out the DC output voltage of the rectifier.
Towards a general fuzzy ontology and its construction

Most of the current fuzzy ontologies are too domainspecific and don’t support reasoning on fuzzy descriptions. By investigating the uncertainty information in the real world, we discover three widely existing general fuzzy relations. Based on such investigation and motivated by the desire to support reasoning and guide fuzzy ontology construction, we propose a reasoning-enabled general fuzzy ontology including these general fuzzy relations. To support such ontology in theory, we introduce a fuzzy description logic ef-SHIN, and define its syntax and semantics. Besides, a reference process for guiding the construction of fuzzy concept base relations in fuzzy ontology is also presented.
