Wireless wideband DS-CDMA point-to-multipoint system for distance education services.

A reVIew of possible distance education services is gIVen. These servIces range from narrowband to broadband, from real to non-real time and from broadcast to fully interactive services. The service target groups include the rural schools and communities who are scattered in remote areas. The performances of multiple access techniques, FDMA, TDMA and CDMA when in use for the provision of point-to-multipoint multimedia services is compared. A hybrid of the satellite and terrestrial access networks for the implementation of the distance education services is presented. The feasibility of implementing the proposed satellite network as part of the total network using the FDMA technique is presented. The rest of the work done in the thesis concentrates on the terrestrial network. The terrestrial part of the network is based on fixed cellular DSCDMA techniques. The fixed cellular network's specifications, modelling and a discussion of the capacity, BER performance, bandwidth requirements and coverage are presented. The link budget estimation of the performance is given. Lastly a review of propagation characteristics for a terrestrial rural environment and a review of DS-CDMA concepts are presented in the appendix. E 0 Maragela 2001 University of Durban-Westville
Visitor perceptions of alternative transportation systems and intelligent transportation systems in national parks

Visitor Perceptions of Alternative Transportation Systems and Intelligent Transportation Systems in National Parks. (August 2003) Virginia Ann Dilworth, B.S., California State University at Sacramento; MBA, Bentley College Chair of Advisory Committee: Dr. C. Scott Shafer This dissertation examines the potential use of intelligent transportation systems (ITS) and alternative transportation systems (ATS) in national parks. Visitors at two of the national park units in California, Golden Gate National Recreation Area (GOGA) and Sequoia and Kings Canyons National Parks (SEKI), were surveyed during May and July 2002 regarding their attitudes and intentions toward a variety of transportation and travel planning items (including ITS and ATS tools). There were three principal areas of inquiry: attitude toward transportation and travel planning tools, likelihood of using transportation and travel planning tools, and the difference between intentions for using tools before arriving at the study parks and while at the study parks. The results revealed several key findings. First, there was substantial support for the relationship between attitudes and intentions. Furthermore, both experience with technology and attitude toward technology were predictive of intention to use technology in the study parks. Third, there was a significant difference between the
Rough fuzzy control of SVC for power system stability enhancement

This paper presents a new approach to the design of a rough fuzzy controller for the control loop of the SVC (static VAR system) in a two area power system for stability enhancement with particular emphasis on providing effective damping for oscillatory instabilities. The performances of the rough fuzzy and the conventional fuzzy controller are compared with that of the conventional PI controller for a variety of transient disturbances, highlighting the effectiveness of the rough fuzzy controller in damping the inter-area oscillations. The effect of the rough fuzzy controller in improving the CCT (critical clearing time) of the two area system is elaborated in this paper as well.
Cheating: Gaining Advantage in Videogames

The widely varying experiences of players of digital games challenge the notions that there is only one correct way to play a game. Some players routinely use cheat codes, consult strategy guides, or buy and sell in-game accounts, while others consider any or all of these practices off limits. Meanwhile, the game industry works to constrain certain readings or activities and promote certain ways of playing. In Cheating, Mia Consalvo investigates how players choose to play games, and what happens when they can't always play the way they'd like. She explores a broad range of player behavior, including cheating (alone and in groups), examines the varying ways that players and industry define cheating, describes how the game industry itself has helped systematize cheating, and studies online cheating in context in an online ethnography of Final Fantasy XI. She develops the concept of "gaming capital" as a key way to understand individuals' interaction with games, information about games, the game industry, and other players. Consalvo provides a cultural history of cheating in videogames, looking at how the packaging and selling of such cheat-enablers as cheat books, GameSharks, and mod chips created a cheat industry. She investigates how players themselves define cheating and how their playing choices can be understood, with particular attention to online cheating. Finally, she examines the growth of the peripheral game industries that produce information about games rather than actual games. Digital games are spaces for play and experimentation; the way we use and think about digital games, Consalvo argues, is crucially important and reflects ethical choices in gameplay and elsewhere.
WISPER : a standarized fatigue load sequence for HAWT-blades

WISPER is a variable-amplitude test loading sequence for use in the fatigue evaluation of horizontalaxis wind turbine blades. It has been derived from flap load measurements on 9 different European wind turbines, covering different materials, a wide range of rotor-diameters and various geographical locations. The rationale of developing WISPER (and loading standards in general) has been discussed in an earlier publication introducing WISPER. In this paper the principles of the data processing procedures will be explained, i.e. the subsequent development steps are shown that led from basic input data to final loading standard. Useful information will be supplied to enable potential users of the new standard to judge its validity and applicability to suit their purposes. Quantitative data will not be given here but will be subject of a third publication, giving a complete description of WISPER and its precise derivation steps. This paper has been prepared for presentation at the 1988 ECWEC Conference, to be held in Herning, Denmark on June 6-10, 1988.
Seam in Action

JBoss Seam is an exciting new application framework based on the Java EE platform that is used to build rich, web-based business applications. Seam is rapidly capturing the interest of Java enterprise developers because of its focus on simplicity, ease of use, transparent integration, and scalability. Seam in Action offers a practical and in-depth look at JBoss Seam. The book puts Seam head-to-head with the complexities in the Java EE architecture. The author presents an unbiased view of Seam from outside the walls of RedHat/JBoss, focusing on such topics as Spring integration and deployment to alternative application servers to steer clear of vendor lock-in. By the end of the book, you should expect to not only gain a deep understanding of Seam, but also come away with the confidence to teach the material to others. To start off, you will see a working Java EE-compliant application come together by the end of the second chapter. As you progress through the book, you will discover how Seam eliminates unnecessary layers and configurations, solves the most common JSF pain points, and establishes the missing link between JSF, EJB 3 and JavaBean components. The author also shows you how Seam opens doors for you to incorporate technologies you previously have not had time to learn, such as business processes and stateful page flows (jBPM), Ajax remoting, PDF generation, asynchronous tasks, and more. All too often, developers spend a majority of their time integrating disparate technologies, manually tracking state, struggling to understand JSF, wrestling with Hibernate exceptions, and constantly redeploying applications, rather than on the logic pertaining to the business at hand. Seam in Action dives deep into thorough explanations of how Seam eliminates these non-core tasks by leveraging configuration by exception, Java 5 annotations, and aspect-oriented programming.
Influencia de variables climáticas en el contenido de N en Carya illinoensis Koch

En la Comarca Lagunera se estima que la superficie sembrada de nogal (Carya illinoensis) es de 9,208 ha-1, con un rendimiento aproximado de 1, 459 t de nuez ha-1. Las variedades que predominan en la Comarca Lagunera son Wichita y Western. Cuando la demanda de elementos nutritivos en las plantas no puede ser cubierta, estas dependen directamente de los compuestos almacenados. Uno de los elementos nutritivos más demandante por las plantas para su crecimiento y desarrollo es el nitrógeno (N); la falta de este elemento nutritivo puede provocar un bajo crecimiento. Se pretende tener conocimiento de la influencia de las variables ambientales (temperatura, irradiación y humedad relativa) sobre el porcentaje de nitrógeno almacenado en la biomasa de las dos variedades cultivadas en la zona de estudio (Western o Wichita) con la finalidad de contribuir al manejo agronómico. El objetivo del presente trabajo fue observar la variación del contenido de N en el tallo de nogal y desarrollar una función matemática que describa su comportamiento con respecto a variables ambientales (temperatura, humedad relativa, irradiación). El estudio se realizó en el campo experimental de la Universidad Agraria Antonio Narro Unidad Laguna. Se seleccionaron cuatro árboles de aproximadamente 30 años de edad de cada variedad. Se extrajeron virutas cada mes durante un año (julio de 2016 a junio de 2017). El porcentaje de N total se determinó mediante un analizador de gases, la biomasa se estimó mediante ecuaciones alométricas. Se realizó un análisis de varianza de dos factores (mes y variedad), para observar la diferencia entre el porcentaje de N en el tallo entre los meses. La relación de las variables ambientales con el porcentaje de N en el tallo se determinó mediante una regresión lineal múltiple. El porcentaje de N no fue afectado por los factores (mes y variedad). La temperatura fue la variable que más afectó el contenido de N total en el tallo del árbol en comparación con la humedad relativa e irradiación. No se encontró diferencia significativa entre los meses y las variedades (Western y Wichita). La predicción del contenido de N es menos precisa debido al tamaño del tallo del árbol. El nogal tiende a aumentar el contenido de N cuando se registran bajas temperaturas. Los compuestos almacenados pueden fluctuar en cualquier momento debido a su plasticidad.
A Fatal Case of MSTN Mutation Calf Pancreatitis

Background:Myostatin (MSTN) is related to growth and development. MSTN gene-mutated animals are prone to dystocia and fetus enlargement, but there is no report of pancreatitis. Pancreatitis is a disease of the pancreas caused by the self-digesting effect of trypsin. In animals, pancreatitis often occurs in dogs or cats and manifests as edema, congestion, bleeding, or necrosis of the pancreas. Clinically, symptoms such as abdominal pain, bloating, nausea, vomiting, and fever appear. Elevated levels of amylase in blood and urine. Pancreatitis is very dangerous to the survival of animals. We must pay attention to it.Case presentation: This is a fatal case report of a myostatin (MSTN) gene-mutated calf diagnosed with pancreatitis. Analyses of the blood biochemistry, blood routine, postmortem anatomy and tissue section of the 2-month old calf showed that the pancreatitis indexes α-amylase and serum lipase were higher than those of normal MSTN gene-mutated and wild-type cattle. The pancreas was found to be swollen, dark red and bloody. The structure of the acinar cells of the pancreas was unidentifiable, and massive coagulation necrosis and lysis necrosis filled in the lobules of the pancreas. The interlobular spaces became enlarged, the vessels among the lobules were dilated and congested with obvious edema and blood stasis.Conclusions: Evidence from anatomy, histology, blood physiology, and biochemistry parameters indicate that the myostatin mutated calf died of pancreatitis. There are few reports on the pathology of gene-mutated animals. This is the first case of MSTN gene-mutated bovine pancreatitis.
The virtual hippocampus : spatial common sense for synthetic creatures

This thesis investigates the problem of spatial perception and reasoning in synthetic creatures. Taking the Hippocampus a brain structure that is strongly believed to constitute a "cognitive mapping" system in animals as an inspiration, a system is demonstrated that visually learns cognitive maps. This cognitive map can be used for problems such as self-localization and landmark-learning (and in fact its formation is strongly tied to these processes). The resulting map can also be used as a basis for a model of object-persistence, whereby the creatures can maintain realistic ideas of the location of mobile objects in the world. When all of these systems are integrated into a single brain, the result is a creature that perceives and reasons about physical space in a way that strongly resembles how animals themselves do.

Effects of reducing the time spent on traditional lectures

This paper describes the outcome of a completely revised course implementation for the course Thermodynamics (15 ETCS), a standard physics course at basic level. Historically, this course has been taught in a traditional way, i.e. almost daily lectures combined with a week of lab classes and a written examination concluded the course. Hence, during the roughly 25-30 lectures during the course, most parts of the literature was covered. However, analyzing the results over a 10 year period, where different lecturers has been teaching the course, it can be observed that there are no significant differences in the examination results due to the teacher effort. This observation is not new and of course somewhat disappointing for an enthusiastic lecturer that has a belief in that he/she can make a big difference for the student. With these observations in mind, we set out to do something radically different where the key question is how we get the student to devote sufficient time to pass the exam. Thus, in the revised course implementation, only eight lectures of overview character were given, usually at the start of a week. After each lecture, the students were given eight assignments that they should prepare for, and be able to present, at a seminar that usually occurred at the end of the week. To increase the students’ willingness to actually fulfill the assignment, they were rewarded with a bonus that gave credit at the written exam. The student group performed roughly similar to previous groups on the written exam, but there were a number of differences in the overall performance that will be thoroughly discussed in the paper.
Two Languages at Work: Bilingual Life on the Production Floor

An ethnography about language use, identity and economic survival and mobility in a Canadian manufacturing factory. Inquiring into the meaning of languages for Portuguese immigrant workers, Goldstein explores the questions of why workers do or do not learn official languages of their host countries, why workers do or do not maintain their mother tongues, or why workers are or are not able to exploit their linguistic resources in local labour markets. By examining the context of second language learning, Goldstein challenges researchers and teams to re-examine assumptions about how to best help students in the process of learning a second language.
Millimetric technologies for future vehicle communications

Future intelligent road networks will incorporate communications between vehicles and between vehicles and roadside beacons. The band between 63 and 64 GHz is attractive because of the potential for high bandwidths and the control of radio interference by exploitation of atmospheric attenuation. Implementation of such systems will require demonstration of a number of millimetre-wave technologies at an acceptable price. This paper describes the design, manufacture and demonstration of a variety of antennas and associated components for 63 GHz vehicular systems.
Run-Off-Road Crashes: An On-Scene Perspective

Run-off-road (ROR) crashes, which usually involve only a single vehicle, contribute to a large portion of fatalities and serious injuries to motor vehicle occupants. In this study, the National Motor Vehicle Crash Causation Survey (NMVCCS) data collected at crash scenes between 2005 and 2007 is used to identify the ROR critical pre-crash event, assess the critical reason for the ROR critical event, and examine associated factors present in the pre-crash phase of the ROR crash. The effect of antilock brake system (ABS) and electronic stability control (ESC) on ROR crashes is also evaluated. The results show that over 95 percent of the critical reasons for single-vehicle ROR crashes were driver-related. The most frequently occurring category of critical reasons attributed to drivers was driver performance errors (27.7%) such as “overcompensation” and “poor directional control,” followed by driver decision errors (25.4%) such as “too fast for curve” and “too fast for conditions,” critical non-performance errors (22.5%) such as “sleeping” and “heart attack/other phys-ical impairment,” and recognition errors (19.8%) such as “internal distractions” and “external distractions. ” With the presence of alcohol in the driver, as high as 46.9 percent of driver-related critical reasons for single-vehicle ROR crashes were driver performance errors. The logistic regression analysis shows that the most influential factors in the occurrence of single-vehicle ROR crashes were the factors “driver inattention,” “driver was fatigued,” and “driver was in a hurry. ” In the NMVCCS crashes, for the vehicles equipped with both ABS and ESC, 7.5 percent ran off the road, while for the vehicles equipped with neither ABS nor ESC, 14.6 percent ran off the road. The odds of being involved in ROR crashes for the vehicles equipped with neither ABS nor ESC were 2.1 times greater than the odds for the vehicles equipped with both ABS and ESC. The combined effect of ABS and ESC systems on reducing the ROR crashes is significant, which is consistent with prior evaluation of the long-term effect of ABS and ESC based on the FARS and GES data. This study is the National Highway Traffic Safety Administration’s first effort in evaluating the effectiveness of crash avoidance technologies with the NMVCCS data.

Flexible design of urban water distribution systems

Urban water distribution systems (UWDS) are highly inter-connected and under many uncertainties from water demand, pipe roughness, and component failure. Accurate projections of these uncertainties are almost impossible, and thus it may not be a proper method to design the system to meet its performance criteria for the forecasted scenario. The system is designed for the deterministic not for the uncertainties, as a result it may not be efficient or effective to be operated under different future scenarios. Flexible design is shown as a useful strategy to cost-effectively respond to uncertainties because of its consideration of uncertainties in advance, and has been successfully applied in many engineering systems. The objective of flexible design is to identify flexibility sources in UWDS and embed them into the system design to respond to uncertainties. The thesis discussed different terms to define the property of the system to respond to uncertainties and proposed a definition of flexibility for UWDS. It then proposed different measures to indicate flexibility value and introduced an efficient method to handle numerous uncertain parameters in the model. It also develops an efficient method to identify high value flexibility sources based on the Flexibility Index. Finally the thesis presents a flexibility-based optimisation model that enable water engineers to compare different flexible design alternatives and generate optimal solutions. A definition of flexibility in UWDS is proposed to illustrate broadly its property to respond to uncertainties, since it is not so useful, or at least in this thesis to distinguish similar terms to define the property of the system to respond to uncertainties. Identified flexibility sources by the proposed method is not useful for the flexibility-based optimization model to design a system, but it might be a powerful tool to locate the weak points in the system or provide better update options during rehabilitation of the system. The computational efficiency of the proposed flexibility-based optimisation model was demonstrated by dramatic decreasing on the number of the required hydraulic simulation in the case study. Flexible designs in the case study are more expensive than inflexible design, but have better hydraulic performance under uncertainties.
Improving the experience of exploring a virtual museum - Lund after 1658

Traditional museums are sometimes static, passive and lifeless. Based on previous work on interaction techniques in Virtual Reality museums, the aim of this Master Thesis is to bring this work to the next level. The project will focus on improving the experience of exploring a virtual museum through more realistic modeling and improved navigation and interaction with the objects allocated inside. As a novelty in this kind of virtual museum the interaction is based on the Nintendo Wii controllers -Wiimote and Nunchuck. The Next Engine Desktop 3D Scanner is used to get base meshes for the ob- jects, and Autodesk 3DStudio MAX and Blender are used as modeling tools. The high quality textures for the pictures exhibited in the virtual museum are created with Adobe Photoshop. We implement the navigation and interaction framework with EON Studio. Finally, the Bluetooth stack BlueSoleil and the emulator GlovePIE are the tools selected to connect the Wii controllers to the application. The visual appearance is improved with shadows, and the time of rendering is accelerated using render-to-texture techniques. The final application is a realistic and interactive virtual museum which can successfully be operated with the Nintendo Wii controllers. The result of a subsequent usability test shows that it is highly usable as well. The innovative input devices are very welcome by users in this kind of appli- cations. The use of shadow techniques notably improves the visual appearance and sense of presence when exploring virtual environments. Even if there are still a few aspects which can be improved regarding the interaction, the overall result is very satisfactory.
