Abstract:
Abstract. Understanding reactions of surfactant-amended droplets on difficult-to-wet weed surfaces could help develop application strategies to increase herbicide efficacy. Behaviors of herbicidal droplets containing different emulsifiable anti-evaporation spray adjuvants were investigated by characterizing 250 and 450 µm herbicidal droplet dispersion and fading time on cucurbitaceous leaves placed inside a 20°C chamber at 30% and 60% relative humidity (RH). Droplet maximum coverage area increased with droplet size but not with RH, while droplet fading time increased with both droplet size and RH. Despite 450 µm droplets having greater maximum coverage area than 250 µm droplets, the larger droplets had higher fading rates and lower ratios of maximum coverage area to droplet volume. Droplet maximum coverage area and fading time on leaves were affected by adding spray adjuvants to the herbicide-only solution. The Uptake surfactant was more effective than the other two surfactants (AntiEvap+BS1000 and Enhance) in increasing droplet maximum coverage area and fading time. Compared to the herbicide-only solution, addition of Uptake surfactant to the herbicide solution could increase maximum coverage area by 68% and 52% for 250 and 450 µm droplets, respectively, but addition of AntiEvap+BS1000 or Enhance surfactants did not show significant increase. Similarly, addition of Uptake surfactant to the herbicide-only solution increased droplet fading times by 11.1% and 13.2% at 30% and 60% RH, respectively, for 250 µm droplets and by 34.7% and 2.8% at 30% and 60% RH, respectively, for 450 µm droplets. In contrast, addition of AntiEvap+BS1000 surfactant reduced fading time, and addition of Enhance surfactant did not significantly affect fading time. Therefore, appropriate selection of spray adjuvants for herbicide applications could significantly influence droplet deposit behaviors on cucurbitaceous leaves, leading to improved effectiveness of weed control.

Abstract:
Northern voles and lemmings are famous for their spectacular multiannual population cycles with high amplitudes. Such cyclic vole populations in Scandinavia have shown an unexpected and marked long-term decline in density since the early 1970s, particularly with a marked shift to lower spring densities in the early 1980s. The vole decline, mainly characterized by a strongly decreased rate of change in numbers over winter, is associated with an increased occurrence of mild and wet winters brought about by a recent change in the North Atlantic Oscillation. This has led to a decrease in winter stability and has shortened the period with protective snow cover, the latter considered as an important prerequisite for the occurrence of multiannual, high-amplitude cycles in vole populations. Although the vole decline is predicted to be negative for predators' reproduction and abundance, empirical data showing this are rare. Here we show that the dynamics of a predator–prey system (Tengmalm's owl, Aegolius funereus , and voles), have in recent years gradually changed from 3–4 yr, high-amplitude cycles towards more or less annual fluctuations only.

Abstract:
A new propagation model is proposed for estimating the attenuation of wireless communication signals in woodland environments. After rainfall or snowfall, the components of the woodland area become moist which degrades the received signal level. To take this into account, the model considers wet/dry states of the foliage, and its dependency on the operating frequency. The parameters of the propagation loss model are optimized using the least squares method. To demonstrate the validity and usefulness of the model, computed results are compared with measured data where excellent matching is observed. It is noted that not only the foliage and rainfall affect the propagation phenomenon, but also wet foliage condition after rainfall contributes to the fading of the wave.

Abstract:
This study presents findings on the effect of domestic laundry detergents on the fastness to light of selected fibre reactive dyes applied to cotton. The study was carried out to elucidate the reasons for the accelerated colour loss of cotton garments washed under Australian domestic laundering conditions. Cotton fabric dyed with commonly used reactive dyes were laundered with water only, several domestic detergents and a laboratory formulated neutral detergent, and then exposed to light for two hours in the wet state. Quantities of detergent used were in accordance with the manufacturers recommendations. Exposures were repeated fifteen times equivalent to 30 hours exposure. Colour loss and colour difference were measured after 5, 10 and 15 wash cycles and 10, 20 and 30 hours exposure. When the fabric was exposed wet the colour faded more rapidly than when exposed dry to light. Detergents increased the colour loss even when the fabric was not exposed to light. The presence of an oxidizing bleach (sodium perborate) in the detergent increased colour loss during washing and wet exposure to light. Ultraviolet radiation from the light source, heat, moisture, alkali and oxidising bleach during exposure resulted in hydrolysis of the dye-fibre bond causing dye desorption during washing and rinsing. Water alone increased the fading of the dyes most likely due to presence of dissolved oxygen held within the fibre. The combination of ultraviolet radiation and oxidizing bleaches altered the chemistry of the dye and hence its shade. This was particularly evident on the black dye and one of the navy blue dyes.

Abstract:
This thesis focuses on the practical implementation issues for modeling, simulation, estimation and system identification of wireless fading channels. The state space models are introduced to describe fading channels including flat fading and frequency-selective fading channels. Without measurement data, simulation and estimation of fading channels are related to the motion of the transmitter or the receiver. The state space realizations and the Kalman filtering are derived for Rayleight fading, Ricean fading and frequency-selective fading channels. The inphase, quadrature and envelope components of the received signals are simulated and estimated through the state space realizations and the Kalman filtering. These model parameters are defined by the transfer function of a given Doppler power spectral density (DPSD) associated to several physical factors such as carried frequency, mobile moving speed, signal-to-noise ratio (SNR), an angle and an interval time. With measurement data, system identification is based on the Expectation-Maximization (EM) algorithm together with the Kalman filtering. These system parameters are computed recursively. Various identified results illustrate the processes of system identification for flat fading and frequency-selective fading channels based on the measurement data provided by Communications Research Center Canada (CRC). Measurement data could also be input by users. Finally, a web-based wireless fading channel simulation and estimation system is analyzed, designed and implemented using UML(TM) techniques and Java(TM) programming language. The web-based system can provide friendly interfaces to complete modeling, simulation, estimation and system identification of fading channels. The Web-based simulation and estimation system can be run on the following site: http://www.site.uottawa.ca/∼jzhan037/onlineSystem.html or http://www.site.uottawa.ca/∼chadcha/onlineSystem.html .

This paper discusses one approach to determine a characteristic of West - Java's air and ground segment as a block-box to accomodate radio waves propagation, especially in L-band ranges, by evaluating both the topographical data and radio reception pattern as measured from ground based telemetry receiving-end system. All the measured signals are random and assumed to be stationair and ergodic. In order to characterize the channel for polarization diversity reception, some statistical analysis are applied to the signal strength measured of both - RHCP and LHCP components of 1531 MHz propagated waves as transmitted fr om NC212-200 PK-NZJ-aircraft. Some computer calculated correlograms of measured data are shown herewith, it is focused for a certain radio corridor at radial 265E relative to the ground based receiving antenna. More over some curves of predicted multipath gain factor are also presented to gain more theoretical back ground. When this paper is written, a further field experiments on the matter concerned is beeing conducted.

Abstract:
As vigas celulares ocupam um lugar de destaque crescente na construção de pontes em concreto protendido. Dentro desta opção, a tendência moderna é de se construírem pontes unicelulares cada vez mais largas, o que traz como conseqüência um aumento considerável da flexão transversal em seus elementos, especialmente em suas almas, submetendo-as a uma combinação de cisalhamento com flexão transversal que pode atingir valores importantes. Este trabalho tem por finalidade apresentar um novo critério de dimensionamento das almas das vigas de seção celular, incluindo o caso do estado limite último de fadiga. Este critério foi idealizado a partir de uma análise crítica dos modelos vigentes, os quais são analisados e comparados por meio de gráficos de interação relacionando força cortante com flexão transversal, que permitem a escolha da melhor opção para as situações de projeto. Desenvolveu-se uma investigação experimental, a fim de verificar a validade do critério de dimensionamento desenvolvido. Foram analisados os seguintes modos de colapso: esmagamento das bielas comprimidas de concreto, alongamento plástico excessivo dos estribos e ruptura dos estribos por fadiga. Os resultados experimentais mostraram uma boa aproximação do Critério de Dimensionamento Proposto e revelaram novidades nos ensaios de fadiga: a ruptura dos estribos por fadiga se deu por etapas, um estribo de cada vez, num processo gradual. A ruptura por fadiga ocorreu sistematicamente próximo à ligação da alma com a mesa inferior e não no dobramento dos estribos.
Box-girders have received a growing attention in the field of prestressed concrete bridges. The modern trend is to build wider unicellular bridges, which leads to a considerable increase in the transverse bending moment acting mainly in their webs. These are subjected to a combination of shear force and transverse bending moments, which may reach important values. The purpose of this thesis is to introduce a new design approach of box-girder webs, including the Ultimate Limit State due to fatigue. This design approach is derived from a critical analysis of the current criteria. The different criteria for the design of box-girder webs are analyzed and compared by means of shear-bending moment interaction diagrams as an attempt to identify the more realistic one. An experimental investigation has been undertaken with the purpose of verifying the validity of the new developed approach. The following failure modes have been considered: crushing of the compressed struts, excessive plastic deformation of the stirrups and rupture of the stirrups due to fatigue. The experimental results have shown good agreement with those predicted by the proposed approach. Furthermore, the tests have revealed new aspects of the fatigue behavior: the rupture of the stirrups due to fatigue occurred in stages, one at a time in a gradual manner. In all cases the failure took place near the top face of the lower flange and not at the corner of the stirrups.

The purpose of this thesis is to investigate the efficiency of concept mapping as well as the improvement of nature science learning achievement for elementary school students. To achieve the goods of this study, several activities of web-based concept mapping learning were designed using scaffold fading. In this thesis, two hundred and fifty six fifth grade primary school students were chosen and randomly divided into four groups, which are “No scaffolding group”, “Learning with scaffold-fading group”, “Mapping with scaffold-fading group”, and “Learning and mapping with scaffold-fading group”. After finishing the web-based concept mapping learning activities, the students must work on the test of nature science learning achievement and finally complete the questionnaire on utilization web-based concept mapping learning activities. The research results indicated that “Learning and mapping with scaffold-fading” could efficiently improve both students’ efficiency of concept mapping and students’ learning achievement. Where as “Learning with scaffold-fading”, and “Mapping with scaffold-fading” improve only students’ efficiency of concept mapping. A questionnaire indicated that most students desire to take more lessons in web-based concept mapping learning activities from which most students thought that they could benefit more.

As technology advances, education has gradually move towards digital, compared to the technical development, e-learning is more emphasis on education aspect improve, how to provide meaningful learning for learners has became an important issue. Meaningful learning is not only focused on the content of teaching materials and, more importantly, how to cultivate the ability of learners to self-development, and to provide a correct perception of feelings and values. In recent years, as people realize the importance of meaningful learning, many of the new approach of learning have emerged, "concept mapping" is one of them. Learning through concept mapping can help learners to link new knowledge with old knowledge. However, the traditional concept mapping approach to learning will result in the dependence caused by passive learning; Therefore, this study use the concept mapping methods and strategies as a basis, and with the "Scaffold Fading" to make up for lack of learning concept map, learners not only learn the content of course, but also learn how to catch learning focus, and organizational their own concept map. In this study, we use eXtreme Programming to develop an Rich Internet Application, and associated with e-learning platform Moodle to provide multi-interactive learning. We use the concept mapping teaching with the scaffold fading to replace the chapter-based teaching, in addition to assisting learners to learn, also expected to enhance organizational capacity for the knowledge structure, and provide a meaningful learning environment for learners.

Abstract:
Este documento descreve o trabalho de investigação e desenvolvimento de uma solução baseada em visão por computador para a deteção e prevenção de Síndrome da Visão de Computador. Esta síndrome, é um tipo de fadiga ocular que se carateriza pelo aparecimento de sintomas oculares durante ou após o uso prolongado do computador. Este comportamento, provoca stress dos músculos oculares que, por sua vez, desencadeiam os sintomas supracitados. A fadiga ocular ocorre, frequentemente, depois de longos períodos a ler ou a olhar para ecrãs digitais. Certos tipos de iluminação também podem provocar este tipo de fadiga. Os sintomas incluem: dores de cabeça, olhos vermelhos, irritados / secos e dores no pescoço ou nas costas. A não prevenção desta síndrome leva ao aparecimento de graves problemas a nível da saúde ocular. A fadiga é considerada uma das principais causas do erro humano. A maior parte das vezes, os sintomas são ignorados, apesar da sua importância para o bem-estar físico e mental e do qual depende o nosso desempenho cognitivo. No entanto, é difícil reconhecer o próprio nível de fadiga, pelo que muitas vezes passamos muitas horas a olhar para um computador, podendo provocar graves problemas oculares. Este problema serviu de motivação ao desenvolvimento de uma aplicação web – iSCV, que através de uma câmara do dispositivo em que é executada, é capaz de detetar o nível de fadiga do utilizador em tempo real, permitindo que o utilizador tenha consciência desse cansaço e assim melhorar o seu desempenho e preservar a sua saúde ocular. Para o efeito, a aplicação alerta o utilizador para comportamentos menos corretos, e fornece um conjunto de ferramentas de análise. A aplicação desenvolvida disponibiliza dois modos distintos de funcionamento. O primeiro, tem como público alvo utilizadores de computadores e dispositivos móveis, permitindo detetar e alertar os utilizadores relativamente ao aparecimento de fadiga ocular. Este é o principal modo de funcionamento da aplicação, o qual pode prevenir possíveis consequências, relacionadas com a Síndrome da Visão de Computador (SVC). O segundo modo de funcionamento tem como público alvo condutores de veículos automóveis, sendo capaz de detetar situações de fadiga do condutor e emitir alertas para prevenção de acidentes. O processo de desenvolvimento do trabalho aqui apresentado iniciou-se com uma análise crítica do estado da arte relativamente a técnicas de visão por computador para análise de fadiga, passando depois pela especificação do sistema a desenvolver, implementação, e realização de testes.

Covering the period 2006–11, in this chapter we see how the seeds of destruction that were unknowingly sown in the early 2000s come to fruition. Nokia was collapsing from within well before Apple or Google became competitors, leaving Nokia’s new management team in a difficult position in which developing a successful managerial response to the changed external environment had become all but impossible. Successive reorganizations, a lack of technology leadership, and the collapse of the strategy process all contributed to Nokia rapidly losing its leadership position. The chapter also looks at the options Nokia’s management team considered with regard to its smartphone strategy before ultimately choosing an alliance with Microsoft.

Abstract:
We explore some of the cosmological implications of nonlocal gravity (NLG) theory, in which nonlocality is due to the gravitational memory of past events. Memory dies out in space and time. The fading of memory in time implies that in NLG the strength of the gravitational interaction must decrease with cosmic time. In the Newtonian regime of NLG, the nonlocal character of gravity simulates dark matter in spiral galaxies and clusters of galaxies. However, dark matter is considered indispensable as well for structure formation in standard models of cosmology. Can nonlocal gravity solve the problem of structure formation in cosmology without recourse to dark matter? In this chapter, a beginning is made in this direction by extending nonlocal gravity in the Newtonian regime to the cosmological domain. The nonlocal analog of the Zel’dovich solution is formulated and the consequences of the resulting nonlocal Zel’dovich model are investigated in detail.

Abstract:
This chapter presents a design framework of scaffolding that can be applied in designing adaptive e-learning systems. The framework is primarily grounded in socio-cultural theory and built on a critical analysis of literature on scaffolding. It addresses three key processes in scaffolding (i.e., diagnosis, supporting, and fading) and four conditions for designing scaffolding (i.e., who, what, how, and when). From the historical perspective, this chapter also provides a literature review of adaptive systems. The characteristics of adaptive systems from different paradigms are specifically examined through the lens of scaffolding. To illustrate the application of the scaffolding framework in system adaptation, four web-based e-learning systems are described to demonstrate how various scaffolding strategies are implemented through the design of the systems. In conclusion, issues related to designing scaffolds for adaptive e-learning systems are discussed, and research gaps are identified for future investigation.

Abstract:
The 1970s were marked by dramatic changes in government policies during the governorship of Sir Murray MacLehose. The New Territories became the locus of a planned population shift away from crowded Hong Kong and Kowloon, and the idea of ‘New Towns’, based on Tsuen Wan’s developments, was central. It went hand-in-hand with infrastructural developments, which revolutionized transportation and ended the relative isolation of Tsuen Wan through the MTR. The administration of Tsuen Wan fundamentally changed and the creation of District Boards (later Councils), beginning first in Tsuen Wan, altered the system of political consultation throughout Hong Kong. The 1980s were marked by dramatic changes in economic policies within China, not least in the areas of China adjacent to Hong Kong, which saw industrialization through the Pearl River delta region and de-industrialization in Tsuen Wan. Emergence of a distinctive Hong Kong identity, and a new political culture, emerged as sovereignty over Hong Kong was resumed by China in 1997. Tsuen Wan changed from the working class town that it has been into one dominated by middle class housing developments, much like the rest of Hong Kong, although the villages of the original inhabitants remained.

Abstract:
Cooperative diversity is an effective technique to combat the fading phenomena in wireless communications without additional complexity of multiple antennas. Multiple terminals in the network form a virtual antenna array in a distributed fashion. Even though each of them is equipped with only one antenna, spatial diversity gain can be achieved through cooperation. In this chapter, we discuss relay-assisted single carrier transmissions extending conventional transmit diversity schemes. We focus on distributed space-frequency block coded single carrier transmission, in order to operate over fast fading channels. A pilot design technique is also discussed for channel estimation of this single carrier cooperative system, which shows better channel tracking performance than conventional block-type channel estimations. In addition, spectral efficient cooperative diversity protocols are presented, where the users access a relay simultaneously or transmit superposed data blocks. Interference from the other user is effectively removed by using an iterative detection technique.

Moral psychology indicates that we have a range of quirks which lead otherwise well-meaning people to act badly. These quirks include conformity effects, by which we tend to copy what others do regardless of whether it is good or bad and tend to defer to those we see as authoritative. Framing effects—how a problem is presented—can cause us to change our decisions. We suffer from moral blind spots, in which we fail to notice something is at stake because we act on auto-pilot. Further, the matrix task experiment demonstrates a wide range of external factors predictably modify how honest people are.

In this chapter, we review the optimal power allocation policies for fading channels in single user and multiple access scenarios. We provide some background on cooperative communications, starting with the relay channel, and moving onto mutually cooperative systems. Then, we consider power control and user cooperation jointly, and for a fading Gaussian multiple access channel (MAC) with user cooperation, we present a channel adaptive encoding policy, which relies on block Markov superposition coding. We obtain the power allocation policies that maximize the average rates achievable by block Markov coding, subject to average power constraints. The optimal policies result in a coding scheme that is simpler than the one for a general multiple access channel with generalized feedback. This simpler coding scheme also leads to the possibility of formulating an otherwise non-concave optimization problem as a concave one. Using the perfect channel state information (CSI) available at the transmitters to adapt the powers, we demonstrate significant gains over the achievable rates for existing cooperative systems. We consider both backwards and window decoding, and show that, window decoding, which incurs less decoding delay, achieves the same sum rate as backwards decoding, when the powers are optimized.

Abstract:
As a consequence of the growing interest in wireless communications systems, much effort is being devoted to the channel characterization and modelling. This is obvious since the performance depends fundamentally on the channels under consideration, so a communication system design must be preceded by the study of channel characteristics. This chapter considers the propagation environment in which a wireless system operates. In other words, we are primarily interested in the characterization of radio links between the transmitter and the receiver antenna that will be modelled by randomly time-variant linear systems. Wireless communication channels are usually described by considering three separable phenomena, namely, path loss, shadowing, and multipath fading. In the following, we briefly overview various efforts to characterize such aspects of wireless communication channels. Firstly, in this chapter we address the estimation of signal decay due to propagation loss which is very important in the determination of the necessary transmission power and the coverage area. Although propagation loss models are sometimes quite accurate, they generally fail to predict signal fluctuations due to the effect of the terrain near the antenna. Such a phenomenon of signal fluctuations is usually called shadowing. However, the effect of multipath fading is generally more complex because it does not only change in time but also varies over frequency. As a result, this topic will also be presented in enough depth and a number of statistical models will be studied. Moreover, the various categories of fading will be discussed. Finally, a novel small-scale model derived by the author is presented in order to give a recent application of the theory.

Abstract:
The chapter addresses the mechanism of growth of druses of faden quartz in a tectonically deformed sandstone. A peculiar feature of this type of quartz, the so-called “white tape” represented by fine subparallel cracks with fluid inclusions, appears highly informative about the genesis of the mineral and tectonic regime of its growth. Two stages of formation of druses of faden quartz are recognized. The suggested mechanism is checked for contradictions by means of the event bush method. The proposed event bush model appears to describe a wider range of quartz formation environments and therefore may serve as a conceptual framework for various models of quartz growth in sedimentary rocks.

Abstract:
This chapter summarizes the main arguments of the book and discusses how each of the five shocks shaped the outcomes of the 2015 and 2017 general elections. We reflect on the role played by the three different mechanisms identified in our theory—salience, competence, and party image—which had varying degrees of importance in the impact of each shock. We consider whether the changes might be long-lasting and how new identities may (or may not) replace fading party identities, and the implications our book has for the future of British politics, and for a more general understanding of electoral change.
