Synchronization and resonance effects in nonlinear electronic circuits : with neuroscience applications

En esta tesis se analiza la dinamica de tres sistemas no lineales a traves de sus respectivos modelos teoricos y experimentales. Dos de ellos, el conocido como circuito Chua y el modelo de Hindmarsh-Rose, se usan en estudios de neurociencia. En particular, la principal contribucion se basa en averiguar como se sincronizan este tipo de sistemas oscilatorios y los efectos resonantes que aparecen como consecuencia de la interaccion entre ellos. Para acoplar osciladores de una forma difusiva y unidireccional (o bidireccional) utilizamos basicamente las configuracion maestro-esclavo y en anillo. Por un lado, simulamos computacionalmente el sistema general compuesto de osciladores; extraemos los datos en forma de series temporales aplicandoles un analisis estadistico para averiguar tanto el tipo de sincronizacion como si aparece algun efecto resonante. Por otro lado, disenamos los circuitos electronicos para reproducir el sistema general con el objetivo de contrastar cuan robustos son nuestros resultados. Siguiendo esta linea de investigacion, mostramos la evidencia experimental de la aparicion de cierto orden en un sistema caotico bajo la influencia de una senal caotica. Ademas, tambien mostramos biestabilidad en un sistema neuronal tipo maestro-esclavo. Finalmente, desarrollamos una aplicacion visual que muestra la dinamica de dos neuronas electronicas conectadas a traves de sinapsis quimica y electrica. ----------ABSTRACT---------- This thesis analyzes the dynamics of three nonlinear systems through their theoretical and experimental models. Two of them are used in neuroscience studies Chua's circuit and Hindmarsh-Rose model. In particular, the main contribution is based on figuring out how this type of systems get synchronized and the resonant effects that appear as a consequence of the interaction among them. We use master-slave and ring topology to couple these oscillatory systems in unidirectional (or bidirectional) diffusive manner. On one hand, we numerically simulate a general system compound of oscillators. We extract time series, for their statistical analyses, in order to figure out not only what kind of synchronization exists among them but also if any of them exhibits some resonance effect. On the other hand, we design the electronic circuit associated with the general system, mentioned above, to check how robust the results are. Following this research line, we find the experimental evidence of the appearance of some order in a chaotic system under the influence of a chaotic signal. Moreover, we also run into bistability in a master-slave neural system. Finally, we developed a visual application to show the dynamics of two electronic neurons connected by chemical and electrical synapse.
Establishing the Initial Stage of Psoriasis in Cell Culture

Psoriasis is a chronic and relapsing skin disease that affects approximately 2–3% of the world population and is considered as an inflammatory disease. Defective keratinocyte proliferation and differentiation programs, aberrant immune responses are the major factors that have been implicated in its pathogenesis. Thick scaly plaques, which are psoriasis characteristic formed by the abnormal maturation of keratinocytes and epidermal hyperplasia. The aim of this study is to establish the initial stage of psoriasis model by LPS (lipopolysaccharide) treatment to HaCaT (transformed keratinocyte) cells. MTT assay of LPS was performed to hallmark the initial stage of psoriasis. ELISA assay was performed to determine the cytokine release as response to LPS for psoriasis initial stage. According to the MTT assay results 200 ng/mL used as the test dose and 8µg/mL LPS determined as the toxic dose at 72th hour. LL-37 was the first cytokine whose expression increased in the formation of the immune response. Besides, TNF-α release occurs soon after. The presence of immune system cells is needed to maintain IL-17 and IL-1β release. The cytokine release at the 72th hour decreased to control level due to the lack of immune cells in the culture medium.
Relational transfer in reinforcement learning

Transfer learning is an inherent aspect of human learning. When humans learn to perform a task, we rarely start from scratch. Instead, we recall relevant knowledge from previous learning experiences and apply that knowledge to help us master the new task more quickly. This principle can be applied to machine learning as well. Machine learning often addresses single learning tasks in isolation. Even though multiple related tasks may exist in a domain, many algorithms for machine learning have no way to utilize those relationships. Algorithms that allow successful transfer from one task (the source) to another task (the target) are necessary steps towards making machine learning as adaptable as human learning. This thesis investigates transfer methods for reinforcement learning (RL), where an agent takes series of actions in an environment. RL often requires substantial amounts of nearly random exploration, particularly in the early stages of learning. The ability to transfer knowledge from previous tasks can therefore be an important asset for RL agents. Transfer from related source tasks can reduce the low initial performance that is common in challenging target tasks. I focus on transferring relational knowledge that guides action choices. Relational knowledge typically uses first-order logic to express information about relationships among objects. First-order logic, unlike propositional logic, can use variables that generalize over classes of objects. This greater generalization makes first-order logic more effective for transfer. This thesis contributes six transfer algorithms in three categories: advice-based transfer, macro transfer, and MLN transfer. Advice-based transfer uses source-task knowledge to provide advice for a target-task learner, which can follow, refine, or ignore the advice according to its value. Macro-transfer and MLN-transfer methods use source-task experience to demonstrate good behavior for a target-task learner. I evaluate these algorithms experimentally in the complex reinforcement-learning domain of RoboCup simulated soccer. All of my algorithms provide empirical benefits compared to non-transfer approaches, either by increasing initial performance or by enabling faster learning in the target task.

Performance of error recovery schemes in a fast packet switching network: simulation study

The authors present the results of a simulation study exploring the performance of various error control schemes in a fast packet switching network. Three of the most popular error control schemes are examined: end-to-end, link-by-link, and a combined link/edge scheme. The results of the simulation study suggest that the end-to-end error-control scheme provides superior performance for fast packet switching networks in real-world environments. In fact, when high-speed, low error rate transmission media is utilized for network implementation, the end-to-end error control scheme provides lower network delays for almost all traffic intensities. <<ETX>>
Design and Implementation of a Vehicle Control System Using Smart Phones

Vehicles have been changing as enjoyable ones from just simple means of transportation considering its environments and conveniences. In particular, vehicle remote control and self-diagnostic systems are important services that increase user conveniences and safety. In this study, a system that increases user conveniences through controlling a smart key system in vehicles using wireless communication functions in smart phones is proposed. For implementing it, the communication allowable distance is improved by configuring a smart key system and a smart phone as a master and a slave of the Bluetooth respectively differed from the general way. In addition, different functions in vehicles are configured in such a way that the functions are controlled using a smart phone.
Fundamental Aspects of Interpreter Education: Curriculum and Assessment

What it Means to Belong

THE Last Resistance is a collection of Jacqueline Rose’s essays written for various occasions: lectures, introductory essays and articles written for the London Review of Books. Rose aims to provide a connecting thread between these pieces in the title and in the first essay under the same heading. In the preface she announces that ‘psychoanalysis and literature appear in these essays as forms of resistance, which is the term that gives its title to the book’. We are warned right away that ‘across the world, resistance shifts its meanings and location’. So it does across this book, as Rose acknowledges. Later in the first essay Rose says that she derived the title from the fifth of Freud’s five types of resistance in the first addendum to Inhibitions, Symptoms and Anxiety (1926)*‘the last to be discovered’* a force exerted by the superego, originating, it seems to Freud, ‘from the sense of guilt or the need for punishment’ and opposing ‘every move towards success, including, therefore, the patient’s own recovery through analysis’. This derivation jars with Rose’s initial presentation of psychoanalysis as a form of resistance, Freud’s fifth type being a resistance against the efforts of psychoanalysis, offering ‘repetition, blockage, blind obeisance to crushing internal constraint’. If psychoanalysis is meant to be mobilised as resistance against psychic resistance of the fifth type, it falls in line with resistance which, ‘in the most common political vocabulary’, is ‘tied to liberation . You resist tyranny, you resist oppression, you resist occupation’. Liberationist resistance, however, may not be unequivocal, as the Introduction intimates in its opening example from Irène Némirovsky’s Suite Française, in which the French protagonist tries to maintain her love for a German soldier against the moral and factual pressures of the Résistance. She eventually abandons her aberrant resistance and returns to the politically correct resistance as ‘a true daughter of her nation’. Jacqueline Rose seems to be sympathetic to this development, sharing the novel’s judgment that with this love affair ‘resistance degrades itself, descends a rung into vulgarity’, and approving of Lucile’s resisting Bruno instead of resisting the Résistance. Yet this victory of filial allegiance to the nation is not at all congruent with the book’s evolving purpose of Jacqueline Rose, The Last Resistance, Verso, 2007, £16.99 hardback 978 1 84467 1243.

The Sound of the Plain White Folk? Creating Country Music's “Social Origins”

Although historians of country music have identified the genre's “social origins” in the plain white folk of the early 20th‐century US South, this article examines how intellectuals, including folklorists, anthropologists, and historians, worked actively to create the category of the plain white folk and how country music was ultimately mapped onto this social category. This intellectual work erased possible interracial connections and established country music as an almost exclusively white genre. Finally, the article raises questions about the role of popular music scholars in linking musical forms to “social” explanations.
Selling, Seduction, and Soliciting the Eye: Manet's Bar at the Folies-Bergère

Manet's painting solicits the eye with a luscious “still life” of commodities for sale on the counter next to an attractive saleswoman. Depicting a crowd in the mirror—the modern public of men and some women whose gazes are being solicited—the painting is related to the discourses of mass consumption, the development of department stores, and the expanded visual culture of illustrations and advertising posters during the second half of the nineteenth century.
Speaker independent phoneme recognition with an auditory model and a neural network: a comparison with traditional techniques

Experiments were conducted that compared the phoneme recognition performances of two different preprocessing methods and classification schemes. Results showed that both representations (the auditory model and discrete Fourier transform) and classification schemes (self-organizing feature maps and K-means clustering) perform equivalently in terms of phoneme recognition accuracy (30%) under the conditions tested (high signal-to-noise ratio, average spectral vectors, and five sentences each from ten speakers). However, the two representations make different types of broad class errors. Both the auditory model representation and the neural network classifier have an advantage in providing codebooks with lower distortion and higher entropy than their counterparts. <<ETX>>
A Solar PV Based Multistage Grid Tie Inverter

The inherent advantage of fuel less and maintenance free energy production from solar photovoltaic makes it a very important source of energy. For harnessing power from the solar photovoltaic (PV) cell/array and to supply it to the utility grid, dc to ac inverters is needed. The conventional line commutated dc-to-ac inverter has square shaped line current which contains higher order harmonics whereas PWM based inverters employing IGBT/ MOSFET are less reliable and has low power handling capability. Moreover, a dc-to-dc converter is generally employed along with the inverter circuit to operate the solar PV array at maximum power point. It adds to the cost, which increases with the size of the system. This paper describes a multistage series converter topology for solar PV based grid tie inverter with low harmonic in line current and inbuilt maximum power point tracking (MPPT) features. The developed prototype has been experimentally tested and verified. Keywords: Multistage converter, Grid tie inverter, Maximum power point tracker (MPPT), Total harmonic distortion, photovoltaic system.
Tradeoff Analysis between Spectral and Energy Efficiency Based on Sub-Channel Activity Index in Wireless Cognitive Radio Networks

In recent years, there has been a rapid evolution of wireless technologies that has led to the challenge of high demand for spectral resources. To overcome this challenge, good spectrum management is required that calls for more efficient use of the spectrum. In this paper, we present a general system, which makes a tradeoff between the spectral efficiency (SE) and energy efficiency (EE) in the cellular cognitive radio networks (CCRN) with their respective limits. We have analyzed the system taking into account the different types of power used in the CCRN, namely the spectrum detection power (Zs) and the relay power (Zr). Optimal policy for emission power allocation formulated in the function of sub-channel activity index (SAI) as an optimization problem in order to maximize spectrum utilization and minimize the energy consumption in the base station of the secondary system energy consumption, is subject to different constraints of the main user system. We also evaluate the collaborative activity index of the sub-channel describing the activity of the primary users in the CCRN. The theoretical analyses and simulation results sufficiently demonstrate that the SE and EE relationship in the CCRN is not contrary and thus the achievement of optimal tradeoff between SE and EE. By making a rapprochement with a cognitive cellular network where SBSs adopts an equal power allocation strategy for sub-channels, the results of our proposed scheme indicate a significant improvement. Therefore, the model proposed in this paper offers a better tradeoff between SE and EE.
SAT0643-HPR Points To Consider for Health Professionals Undertaking Musculoskeletal Ultrasound for Rheumatic and Musculoskeletal Diseases: Progress of A Eular Task Force

Background Musculoskeletal ultrasound (MSUS) has evolved into an important method for identifying musculoskeletal abnormalities, confirming the diagnosis in patients with suspected inflammatory arthritis, monitoring therapeutic response, influencing clinical decision making and guiding interventions. The role of the non-medical health professional has advanced with many health professionals undertaking training and using MSUS to extend their scope of practice. Guidelines to support training for rheumatologists have been identified but currently there are not any recommendations to support the education and training needs of non-medical health professionals using MSUS. Objectives The EULAR Task Force was established to reach a consensus on the role and education and training needs of non-medical health professionals undertaking MSUS for the management of patients with rheumatic and musculoskeletal diseases (RMDs). Methods The EULAR Task Force comprised an expert group from 11 European countries. The Task Force met twice and included rheumatologists, nurses, physiotherapists, a radiologist, radiographer and podiatrist with patient representation. In the first meeting the aims of the Task Force were defined and fourteen research questions were developed. This was followed by a comprehensive systematic search of the literature to identify publications on the role of health professionals using MSUS, their competency requirements and training undertaken. During the second meeting the Task Force were presented with the results of the literature review which supported the formulation and consensus of “points to consider”. The level of agreement between task force members for each “point to consider” was determined after the second meeting. Results In total, seven “points to consider” were formulated. Two points covered the role and scope of health professionals using musculoskeletal ultrasound and one point addressed the application and feasibility in daily practice. Three “points to consider” focused on the training and competency required by health professionals and the final point addressed the added value in daily practice. The strength of the “points to consider” was D based on the category of evidence (3–4). A high level of agreement (range 9.0–9.7) was achieved between Task Force members. Additionally, the Task Force agreed upon eight topics for the future research agenda. Conclusions Seven “points to consider” for health professionals using MSUS for the management of patients with RMDs were developed using a combination of research-based evidence and expert consensus approach.

Coming of age under martial law: the initiation novels of Poland’s last communist generation

– some are less convincing in this respect. In fact, some pieces make one wonder whether postcolonial studies is indeed a springboard for revealing new meanings and a way of finding a more in-depth understanding of an area (in this case, Eastern and Central Europe), or rather a formal straitjacket, an academic framework one subscribes to regardless of its merits. To put it otherwise, one notices a kind of paradox present at times in the volume, and which is epitomised by its very title: the postcolonial framework tends to become a new form of assumed external power, which sometimes seems to take over or guide research in the area. Various authors clearly point to the liberating character and the nuanced interpretation that Saidian or Fanonian perspectives bring in the post-communist spaces; on the other hand, the way the Eastern European cultural legacy can contribute to postcolonialism or theoretical studies elsewhere is not present. Irrespective of this and various minor shortcomings, the volume is a major achievement. It introduces to the Anglophone world numerous less known contexts and critical voices, as well as a wealth of topics and avenues for further research.
Partial Caching Scheme for Streaming Multimedia Data in Ad-hoc Network

The streaming technique is a sequence of data made available over time. In the ad-hoc network, the streaming service is hardly served as the path is frequently broken due to the movement of nodes. In this paper, we propose partial caching scheme to reduce the service blocking rate. With the proposed scheme, mobile nodes store the data passing through and by-passing themselves. The cache replacement algorithm is based on the popularity of multimedia contents and the distance of the data block. This has resulted in the increases of the probability that mobile node stores the data to be used in future request. In evaluation, we examined our proposed scheme in the view of the cache hit ratios as the function of the number of mobile nodes and in the view of service block rate as the function of the service request rates. The simulation results show that the proposed caching scheme has better performance in cache hit ratio and service blocking rate.
