description: We study diffusion-reaction-advection models describing population dynamics of aquatic organisms subject to a constant drift, with reflecting upstream and outflow downstream boundary conditions. We consider three different models: single logistically growing species, two and three competing species. In the case of a single population, we determine conditions for existence, uniqueness and stability of non-trivial steady-state solutions. We analyze the dependence of such solutions on advection speed, growth rate and length of the habitat. Such analysis offers a possible explanation of the "drift paradox" in our context. We also introduce a spatially implicit ODE (nonspatial approximation) model which captures the essential behavior of the original PDE model. In the case of two competing species, we use a diffusion-advection version of the Lotka-Volterra competition model. Combining numerical and analytical techniques, in both the spatial and nonspatial approximation settings, we describe the effect of advection on competitive outcomes. Finally, in the case of three species, we use the nonspatial approximation approach to analyze and classify the possible scenarios as we change the flow speed in the habitat.

description: The purification of hydrometallurgical process solutions by Fe(III) precipitation is a common and large-scale industrial operation. This step is notorious for valuable metal loss occurring with the iron precipitation product, which is usually directed to tailings. In this study, factors affecting Fe(III) precipitation and associated copper loss were studied in synthetic process solutions using statistical methods. The variables studied were: Initial acid concentration, retention time, seed addition, and initial Fe(III), Cu(II), and chloride concentrations. The importance of each variable and its interaction effects were studied against two responses, i.e., percent of Fe(III) precipitated as hematite and percent of Cu lost to solids. The results showed that a combination of high acid and moderate seeding was required to simultaneously achieve high proportions of Fe(III) precipitated as hematite and lower copper loss to the precipitates. High acid concentrations create low supersaturation for Fe(III), which minimizes the consequences of homogeneous nucleation and favors particle growth.

description: Wireless local area networks (WLANs) and wireless sensor networks (WSNs) technologies have been comprehensively developed and deployed during recent years. Since commercial WLAN and WSN products share the same free of license frequency band, the low power, low rate ZigBee based WSNs are vulnerable to the interference from Wi-Fi WLANs. Therefore, it is important to evaluate the performance of ZigBee WSNs that are subjected to interference generated by collocated Wi-Fi WLANs and to design effective counter-measuring techniques should performance improvement is needed. In this research, a versatile testbed for conducting various experiments is established and the ZigBee system’s performance with different clear channel assessment (CCA) modes and energy detection (ED) thresholds are evaluated through extensive experimental measurements in the testbed. It can be concluded from the results that CCA has significant impact on ZigBee’s performance. An existing theoretical analysis approach that is based on the collision time model between ZigBee and Wi-Fi packets is suitably modified to provide analytical evaluation means of the cases we examined. In order to mitigate the interference from the collocated Wi-Fi system, a novel and effective interference-aware adaptive CCA (IAACCA) scheme is proposed and implemented as firmware flashed into Crossbow motes. Experiments confirmed the ability of IAACCA to countermeasure effectively interference generated by Wi-Fi and thus improve the performance of ZigBee WSNs. Finally, a thorough statistical analysis is performed to understand the factors impacting the performance of ZigBee system and is used to further verify our experimental methods.

Gebser and the radical enlightenment
Creators: name: Gare, Arran
Publisher: name: Swinburne
Year: 2024

description: Jean Gebser’s work is devoted to showing that the crisis of Western culture, manifest in the turmoil of the twentieth century, was part of a restructuration. This restructuration, manifest in diverse disciplines within the natural and human sciences and the humanities and in new art and literary forms, involves a mutation of consciousness leading us into the ‘aperspectival age’. Gebser represented this as one of a number of major mutations of consciousness that have taken place through the history of humanity, in the transformation from the archaic to the magical, from the magical to the mythical, from the mythical to the mental, and then from the unperspectival to the perspectival. The birth of the aperspectival consciousness, Gebser suggested, began with the irruption of time into our consciousness, not as an analytical system of measurable relationships, but recognized as a quality and an intensity. In accordance with this new appreciation of time, Gebser did not portray the coming mutation as inevitable. It is a challenge to achieve it. There is nothing automatic about such mutations. As he put it, ‘if we do not overcome the crisis it will overcome us’. This suggests a long struggle to effect this mutation, which in turn suggests that such mutations are associated with conflicts between structures of consciousness over extended durations. Here I will argue that the beginnings of the new consciousness celebrated and promoted by Gebser extends further into the past than Gebser realized, to the Renaissance. The first manifestations of this new consciousness were suppressed and almost aborted with the persecution of its greatest proponents (such as Giordano Bruno) and, in the seventeenth century, with the development of the mechanistic world-view and possessive individualism designed specifically to combat it. However, the abortion was not completely successful, and the new consciousness revived as what has now come to be known as the Radical Enlightenment, perhaps the ‘true’ enlightenment as opposed to the ‘fake’ enlightenment of proponents of the ideas of Newton and Locke. Gebser’s work and the developments in consciousness he identified can thus be appreciated as part of this Radical Enlightenment, and conceiving it in relation to this longer history, I will suggest, highlights the need for and could improve the chances of effecting the mutation of consciousness Gebser called for.
The Role of PJA2-CDK5R1 in β-cell Function
Creators: name: Mohamud, Yasir
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2015

description: Diabetes is a global epidemic characterized by an inability to control blood glucose due to lack of insulin secretion and/or regulation. The International Diabetes Federation (IDF) estimates approximately 382 million people worldwide to be affected by diabetes and domestically, the Canadian Diabetes Association estimates approximately 9 million diabetic/pre-diabetics. The protein Cdk5r1/p35 negatively regulates insulin secretion and thus can be targeted as a novel therapy for diabetes. Immunoprecipitation coupled with mass spectrometry has identified candidate interactors of p35. Using high throughput RNAi screening, candidate genes were knocked down with target shRNA and p35 protein levels were monitored. The screen identified RPAP3 as a potential regulator of p35 levels. Knockdown of RPAP3 increased p35 protein levels however insulin secretion was unaffected suggesting a more complex model. In the same manner, PJA2 was identified as the E3 ligase responsible for p35 ubiquitination and subsequent degradation. With the preface that PJA2 undergoes auto-ubiquitination, site-directed mutagenesis was employed to generate lysine to arginine mutants in an effort to identify auto-ubiquitination sites. Mutating lysines K642, K657, and K666 (K3R) causes PJA2 stabilization and reduced auto-ubiquitination compared to wild-type. In vitro ubiquitination assays demonstrate that K3R is functional and can ubiquitinate GST-p35. However, overexpression of PJA2 in Min6 cells is associated with poor regulation of insulin secretion. Co-immunoprecipitation experiments reveal that PJA2 undergoes self-interaction. PJA2-p35 interaction is further characterized by demonstrating that p25 is sufficient to interact with PJA2. Furthermore, PJA2-p35 dynamics may affect PJA2 auto-ubiquitination capacity.

The Impact of Chlorine Substituents on the Regioselectivity of Pd(0)-catalyzed Direct Arylation of Heteroaromatics

description: The regioselectivity in Pd(0)-catalyzed direct arylation of pyrrole, thiophene, and indole can be improved by blocking some of the reactive sites with a chloride group, leading to increased yields of the desired regioisomers. Competition experiments and computational studies show that the blocking group also activates the substrates toward arylation. Due to the activated nature of chlorinated heteroaromatics, rare and sought after regioisomers, such as 3-arylthiophenes, can be obtained under mild conditions in good yields. Chlorine-bearing thiophenes arylated at C3 and C4 have the potential to undergo controlled regioregular polymerization under conditions developed in the field of polythiophene chemistry. Mechanistic studies support the hypothesis that the arylation of the substrates under investigation likely proceeds via the CMD transition state.

description: Cette étude avait pour but d’examiner l’expérience du stress au travail et des stratégies d’adaptation des thérapeutes qui travaillent auprès de femmes immigrantes victimes d’abus conjugal. En suivant une méthodologie qualitative, cette recherche tentait de répondre aux questions suivantes : 1) Quelle serait la nature du stress au travail des thérapeutes qui interviennent auprès des immigrantes victimes d’abus conjugal ? Comment ce stress se développe-t-il ? 2) Comment ces intervenants tentent de s’adapter au stress ? Les quatre participantes de cette étude ont passé une entrevue semi-dirigée et l’analyse des données suivait la méthode de codification en théorisation ancrée proposée par Strauss et Corbin (1998). Quatre catégories principales composent la théorie préliminaire émergente : les manifestations du stress, les facteurs de stress, les éléments d’adaptation au stress, ainsi que les recommandations des participantes. Le stress s’exprimait notamment par le biais des émotions et portait aussi une atteinte à l’identité et à la pratique professionnelle des participantes. Les sources de stress provenaient des caractéristiques et problématiques présentées par la cliente, se retrouvaient aussi au sein de la vie professionnelle et personnelle des participantes, ainsi qu’au niveau organisationnel. Afin d’atténuer les effets négatifs du stress, les participantes avaient recours à des stratégies d’adaptation au travail et dans leur vie personnelle, ainsi que des facteurs de résilience. Enfin, les participantes ont pu offrir des recommandations importantes tant au niveau de la formation qu’au niveau de la pratique. Cette étude offre ainsi des pistes de recherche et d’intervention intéressantes à l’égard de la formation initiale, la supervision, et le développement professionnel des thérapeutes qui interviennent auprès des immigrantes souffrant de la violence conjugale.
Cultural Policy in the Digital Age: The Emergence of Fans as Political Agents in Copyright Discourse

description: Cultural policy theory operates on a division between producers and the public. Dualisms, such as producer/consumer – or, in more nuanced circles, the triadic relationship of consumer/producer/owner – have had a structuring effect on the way in which we envision cultural policy theories. At its core, the producer/consumer dualism implies subjectivities – that is to say that it defines positions in relationships between socio-political actors/actresses. At the governmental level, such clear-cut subject positions are perceptible beyond theories, entering into the actual practice of policy-making to the point where certain policies structure the notion of the public (or consumers), and the producers and/or owners. Copyright law, for instance, represents a good example of such an ideational construct. As a form of cultural policy, copyright law seeks to define the rights of producers with regards to their productions. Consequently, this thesis aims at exploring the forms of agency that develop and challenge both the practice and theoretical constructs of cultural policy. Two aspects command us to question anew these boundaries, one based on contemporary social and technical transformations (the rise of the digital age), and one based on cultural practice (in this case, those of fans and fandoms).Borrowing from theories of cultural studies and Foucauldian approaches to discourse analysis, this thesis explored the emerging discourses surrounding fans and their use of copyrighted material via the internet. Putting emphasis on three fandoms that have had marked histories of fan activism and fan production via the use of copyrighted material – Star Trek, Firefly, and Harry Potter – this paper investigated fans’ use of copyrighted material in developing fan cultures and as a vehicle for their discursive practices. These cases illustrate how fans have challenged the established repertoires of subjects in cultural policy (making and theory), and how their form of agency represents an interesting case of resistance to the rise of the cultural industries conception of cultural policy.
Signal and Noise Time –domain Models for Microwave FETs
Creators: name: Asadi, Shahrooz
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2011

description: Accurate characterization of active devices is one of the most crucial steps in efficient microwave circuit design. As the operating frequency increases, the dimensions of the electrodes of microwave transistors such as FETs become comparable to the wavelength, highlighting the parasitic effect of wave propagation and phase cancellation. Thus, this effect needs to be accurately evaluated in the device model to assure a reliable design. In this work, we proposed new small- and large-signal FET models for efficient millimeter-wave circuit design. In our approach, the device width was divided into an infinity number of segments, while each segment was considered as a combination of three coupled lines and a conventional FET equivalent circuit. By solving a set of multiconductor transmission line equations using the Finite-Difference Time-Domain (FDTD) technique, an accurate and efficient transistor modeling approach has been introduced. Furthermore, a new distributed noise FET model was proposed. It consists in a threecoupled excited transmission line (TL) structure in which the Laplace transformation was applied to determine the noise currents and voltages of lines. The structure was also analyzed by applying the Green's function concept as a wave approach. The proposed distributed mm-wave noise FET model has been demonstrated through successful comparison with measurements.

description: This report supports the implementation of European regulations on biocidal products for the product types 7, 9 and 10. ⁠Emission⁠ of active substances from material preservatives into environmental compartments can occur due precipitation. Risk characterisations have to be based on estimations of environmental concentrations of target substances leached from material preservatives. Harmonised test procedures are required to predict environmental impact due to leaching. Seventeen treated articles, mainly paints, but also a textile, sealing tapes and sealing masses were investigated by intermittent contact to water to prove suitability of the proposed laboratory and field test procedure.
Three body recombination of ultracold dipoles to weakly bound dimers

Year: 2024

description: We use universality in two-body dipolar physics to study three-body recombination. We present results for the universal structure of weakly bound two-dipole states that depend only on the s-wave scattering length (a). We study threshold three-body recombination rates into weakly bound dimer states as a function of the scattering length. A Fermi golden rule analysis is used to estimate rates for different events mediated by the dipole-dipole interaction and a phenomenological contact interaction. The three-body recombination rate in the limit where a≫D contains terms which scale as a4, a2D2, and D4, where D is the dipolar length. When a≪D, the three-body recombination rate scales as D4.

description: The development of useful models for predicting and controlling Oxygen Steelmaking is very difficult because of the complex multi-phase physics and chemistry of the process. In particular, the relationship between the physics of droplet generation and behaviour in the emulsion with the physico-chemical behaviour of the droplets has been difficult to quantify. Recently, researchers at Swinburne University of Technology have been developing models that link the dynamic physics associated with the lance with the chemical processes. This has resulted in a more comprehensive understanding of the process dynamics of the oxygen steelmaking and a fully predictive model for the de-carburisation kinetics is under development. Result and discussion on how this work impacts on the practical operation of steelmaking furnaces will be discussed in the paper.

description: Longtemps oubliée, la victime est aujourd’hui au centre des préoccupations politiques, juridiques et scientifiques. Depuis les années 2000, la réflexion sur les victimes s’est orientée vers la reconnaissance de leur place au sein des institutions et particulièrement au sein de l’institution pénale. Elle est largement discutée dans deux courants de pensée : l’approche critique et l’approche institutionnelle qui proposent des solutions radicalement opposées. Suivant une méthode qualitative et une approche phénoménologique du phénomène à l’étude, cette recherche propose un regard sur la perspective de treize victimes de crimes « graves ». À partir d'entretiens semi-directifs menés auprès des victimes et de leurs proches, la présente étude tente de faire ressortir leurs perceptions par rapport aux démarches entreprises et aux réponses de justice qui leur furent adressées. Elle tente de mieux saisir leur demande de justice, leur souci de régulation mais aussi de gestion des conséquences du crime.

description: Le dossier testamentaire est une source exceptionnelle en matière d’histoire de la mort au Moyen Âge. Composé des écrits du testament, de l’inventaire après décès et du compte de l’exécution, il couvre toutes les étapes de l’administration de la mort, des fondements pré décès, aux articulations concrètes de la réalité post mortem. L’étude des dossiers de deux chanoines parisiens, Jean d’Hétomesnil (Sainte-Chapelle, 1381) et Jean Chuffart (Notre-Dame de Paris, 1451) a permis d’esquisser les dynamiques de tels documents. La cohérence idéologique et codicologique laisse d’abord apparaître l’état post mortem du réseau social des défunts. Défini par une mobilisation de ses constituants et axé sur la mémoire et la rédemption de l’âme, cet état résulte de l’activation des dispositions testamentaires. Ensuite, ce processus est exprimé à partir de la perspective de l’exécuteur testamentaire : elle souligne la somme de travail requise et les paramètres d’exécution. L’utilisation de ces documents permet ainsi de dépasser l’état spéculatif des dernières volontés et d’entrer dans la complexité de leur réalisation. En définitive, c’est la protection des exécuteurs et la démonstration du respect des dernières volontés dans un cadre d’autorité bien plus que la rédemption de l’âme qui ressort comme la motivation principale des dossiers testamentaires.

description: Golf is an important and growing industry in South Africa that currently fosters the creation of an informal job sector of which little is known about the health and safety risks. The purpose of the study is to investigate the prevalence and significance of musculoskeletal pain in male caddies compared to other golf course employees while holding contributing factors such as socioeconomic status, age, and education constant. Cross-sectional data were collected and analyzed from a convenience sample of 249 caddies and 74 non-caddies from six golf courses in Johannesburg, South Africa. Structural interviews were conducted to collect data on general demographics and musculoskeletal pain for two to three days at each golf course. On average, caddies were eight years older, had an income of 2880 rand less a month, and worked 4 h less a shift compared to non-caddies employed at the golf courses. Caddies were approximately 10% more likely to experience lower back and shoulder pain than non-caddies. Logistic regression models show a significantly increased adjusted odds ratio for musculoskeletal pain in caddies for neck (3.29, p = 0.015), back (2.39, p = 0.045), arm (2.95, p = 0.027), and leg (2.83, p = 0.019) compared to other golf course workers. The study findings indicate that caddying, as a growing informal occupation is at higher risk for musculoskeletal pain in caddies. Future policy should consider the safety of such a vulnerable population without limiting their ability to generate an income.

description: Pennsylvania, home to diverse ecosystems and significant water basins, continues to play a pivotal role in maintaining the environmental health of the Chesapeake Bay Watershed. Educating citizens about the importance of their relationship with natural systems is critical to sustaining the health of Pennsylvania’s waterways and terrestrial ecosystems. The role of formal and non-formal environmental educators in shaping environmentally literate citizens has never been more important. Educators foster an understanding of ecosystems that can transform environmentally passive residents into active stewards of the environment.

description: Вопросы оценки текущей ситуации имеют особую актуальность. При разработке модели функционирования рисовой оросительной системы следует рассматривать схемы влияния отдельных факторов среды на урожай риса, имея в виду, что для каждой фазы развития растения характерны свои оптимальные значения влияющих факторов. Прогнозы по текущему состоянию растений можно использовать для установления количественных связей урожая с особенностями растений, агроклиматическими, почвенными, агротехническими и другими факторами. Исследования мелиоративного состояния земель требуют получения и накопления информации по огромным территориям. Поэтому успешная их реализация немыслима без применения современных дистанционных методов прослеживания, включая аэрокосмические с последующим их дешифрованием. В работе предлагается методика обработки экспериментальных данных съемок на рисовых оросительных системах для выработки стратегий хозяйственных решений. Технология основана на использовании мультиспектральных данных дистанционного зондирования Земли и выборочной диагностики содержания азота на тестовых участках рисовых чеков. При этом максимальное снижение стоимости и повышение оперативности агрохимического анализа достигается за счет применения N-тестера.

description: The purpose of this investigation was to develop and validate mathematical models of the sprint relay race. Two approaches, a classical exponential approach and a "new" polynomial approach, were chosen for implementation. Archival film of a 100 m sprint was used to gather displacement data for the first 60 m of the race. Filming had been performed with a single highspeed 16 mm cine camera (LOCAM) at 50 fps. The coordinates were digitized, scaled and filtered using a low pass, critically damped, 4$\sp{\rm th}$ order, zero-lag Butterworth digital filter with a 1 Hz cutoff frequency. Linear velocities were calculated using finite differences. A sprinter was modelled in two ways. The first was an Exponential Model which required as input a personal best time for the 100 m race and the sprinter's maximum constant velocity. The second was a Polynomial Model which required as input the parameters mentioned in the Exponential Model and, additionally, the displacement coefficients for the first 60 m of the 100 m sprint. Relay software was developed to piece the sprint relay together using the corresponding exponential or polynomial approach. The results indicated that the relay software reasonably simulated the kinematic and temporal quantities of a 4 x 100 m relay and can be used by coaches to gain insight into the sprint relay without risking injury to their athletes. Furthermore, the Exponential Model, using less information, described the sprinter's kinematics better than the Polynomial Model.

description: Рациональное использование и охрана почв и водных ресурсов – важнейшие условия успешной интенсификации сельского хозяйства. Промышленные и сельскохозяйственные предприятия наносят вред окружающим почвам и водоемам. Для разработки эффективных методов охраны почв и водных ресурсов необходимо учитывать все взаимосвязи между отдельными природными и экономическими факторами. В статье авторы предлагают комплексное решение проблемы защиты окружающей среды при проектировании систем удаления навоза на животноводческих фермах, рассматривая количественные соотношения между параметрами, характеризующими исследуемые процессы. Выполнен анализ состояния вод в реке Ея по гидрохимическим показателям с использованием математической модели. При исследовании экологической системы реки Ея использованы данные Гидрометслужбы и института «Кубаньгипроводхоз». Сделаны выводы о том, что деятельность любой животноводческой фермы, любого сельскохозяйственного предприятия даже небольшого масштаба, должна сопровождаться постоянным мониторингом экологической ситуации с привлечением научных достижений, их внедрением в оценку производств и своевременной корректировкой результатов своей работы в направлении сохранения окружающей среды, чистых почв, водоемов и воздуха.

description: We demonstrate enhancements in photocurrent and conversion efficiency for thin-film Si cells on glass due to plasmonic light-trapping. In this work, silver nanoparticles were formed on the rear surface of evaporated solid-phase-crystallised poly-Si thin-film solar cells coated with an intermediate dielectric layer. We find that localised surface plasmon excited in nanoparticles can increase the light absorption of the Si films and thereby enhance the spectral response and efficiency of the cells. Short-circuit current and efficiency under standard illumination condition increased by 13% and 10% respectively compared to the same cell without surface plasmons. This is a very important finding as evaporated Si thin-film solar cells have few options for effective light trapping which are simple and do not harm the cell structure, like surface plasmons. Effects of different dielectric layers on enhancement are also investigated.
Elucidating the Functional Role of TDRD3 in Stress Granules

description: Tudor domain-containing protein 3, TDRD3, was first identified in a proteomic survey of the spliceosome machinery. Although its function remains elusive, elevated TDRD3 gene expression is associated with poor prognosis of estrogen receptor-negative breast cancer. The Tudor domain of TDRD3 is highly similar to the Tudor domain of the survival of motor neuron (SMN) and accordingly, it has been shown to bind dimethylated arginine residues. Our lab has previously demonstrated the association of TDRD3 with the translation machinery and most importantly, its localization to stress granules (SG) upon various cellular stresses. In this study, it was revealed that TDRD3 knockdown facilitates and accelerates SG assembly and consequently accelerates SG disassembly. Moreover, we showed that wildtype TDRD3 rescued this defect while a mutation in the Tudor domain of TDRD3, E691K, was not able to do so. Taken together, these findings allude to a prominent role for TDRD3, via its Tudor domain, in the proper formation of SGs.

description: Последние десятилетия аграрное и научное сообщество беспокоит состояние российского села, его «исчезновение» с карты России. Развитие сельских территорий обозначено приоритетным направлением экономической политики государства, а развитие малых форм хозяйствования становиться точкой опоры сельских территорий. Крестьянские (фермерские) хозяйства играют значительную роль в развитие современного агробизнеса, они выходят на лидирующие позиции по производству зерна, картофеля и овощей. Для обеспечения их деятельности государством создаются отдельные системы поддержки в виде грантов, субсидий и выделения земельных участков. Новгородская область не исключение, региональные программы поддержки позволяют фермерским хозяйствам осваивать новые технологии, развивать семейные животноводческие фермы, повышать поголовье крупного рогатого скота, осваивать последующую переработку сельскохозяйственной продукции. Действия региональных властей в первую очередь направлены на снижение миграционных процессов, улучшение инфраструктурных объектов, повышение уровня занятости сельского населения и увеличениях их реальных доходов. Сегодня мы видим высокую значимость фермерства для развития сельских территорий и аграрной отрасли региона. Положительный опыт еще раз подтверждает необходимость и дальше поддерживать инициативы сельского населения в увеличении сельскохозяйственных угодий, создании производственной инфраструктуры, развитие кооперации, формировании государственного заказа. Для этого, в первую очередь, необходима государственная поддержка, внедрение инновационных преобразований, вливание частных инвестиции и конкретные действия региональных властей.

description: Road traffic signs provide instructions, warning information, to regulate driver behavior. In addition, these signs provide a reliable guarantee for safe and convenient driving. The Traffic Sign Detection and Recognition (TSDR) system is one of the primary applications for Advanced Driver Assistance Systems (ADAS). TSDR has obtained a great deal of attention over the recent years. But, it is still a challenging field of image processing. In this thesis, we first created our own dataset for North American Traffic Signs, which is still being updated. We then decided to choose Histogram Orientation Gradients (HOG) and Support Vector Machines (SVMs) to build our system after comparing them with some other techniques. For better results, we tested different HOG parameters to find the best combination. After this, we developed a TSDR system using HOG, SVM and our new color information extraction algorithm. To reduce time-consumption, we used the Maximally Stable Extremal Region (MSER) to replace the HOG and SVM detection stage. In addition, we developed a new approach based on Global Positioning System (GPS) information other than image processing. At last, we tested these three systems; the results show that all of them can recognize traffic signs with a good accuracy rate. The MSER based system is faster than the one using only HOG and SVM; and, the GPS based system is even faster than the MSER based system.
