Повний текст джерелаnamely the classical Coulomb with viscous friction model, the Stribeck friction model, the LuGre friction model, and the Generalized Maxwell-Slip (GMS) friction model. All friction models are applied to the system together with the same linear, proportional with derivative (PD)-type and proportional with integral and derivative (PID)-type feedback control actions for the sake of being faithful in comparison. The accuracy of the friction compensation methods is examined separately for both the low-velocity and high-velocity motions of the system. The precision of friction estimation is also shown in the case of using both the desired velocity and measured velocity as an input to the friction models. These control studies are verified in simulation environment and the corresponding results are given. Furthermore, an experimental set-up is designed and manufactured as a case study. The parameters of the aforementioned friction models are identified and the control laws with different friction models are applied to the system in order to demonstrate the compensation capabilities of the models. The results of the experiments are evaluated by comparing them among each other and with the simulation results.

The focus of my research is the development of technology for building compound biological systems from simpler pieces. I designed BioScaffold parts, a family of variable regions that can be inserted into a DNA sequence so that at a later time another set of pieces can be substituted for each variable. The variable regions are selective so that a particular piece can be targeted to each region. I have used this technique to assemble protein domains, tune the expression levels of proteins and remove BioBrick scars. BioScaffold parts can be used in combination with BioBrick Standard Biological Parts to create and store devices with tunable components. I developed simplified methods to produce and examine SbpA, a protein that can either self associate into two-dimensional crystals or bring together fused enzymes when divalent cations such as calcium are added to the protein monomers. My fast and easy purification protocol allows SbpA to be produced under non-denaturing conditions as well as examination of the native state of the protein monomers before crystallization. The absence of a white precipitate when calcium is added to SbpA monomers concentrated to 1 mg/ml provides a simple visual screen that indicates that the protein has failed to crystallize. I also developed a protocol to embed SbpA crystallized on lipid monolayers in trehalose for electron microscopy, allowing creation of a 7 Å resolution map for SbpA. I created a cells-on-paper system to compose, isolate, and subsequently destack and examine different cell types grown in sheets of ordinary filter paper and maintained in a humidified incubation chamber. I found that E coli diluted in LB broth and then applied to filter paper grew at rates similar to the same culture spotted on agar plates. Track etch membranes could be used to isolate different cell types, while still allowing chemical communication between the layers. Use of plasmids that contain fluorescent proteins allowed the behaviour of cells to be tracked using a scanner after destacking of the layers. The cells-on-paper system can be used both to test and construct modular synthetic systems composed of bacterial ensembles and to create and examine the behavior of compositions of cell types typically found in biofilms.

Повний текст джерелаEste projecto visa a produção de um aparelho portátil para monitorização/análise da actividade cardíaca. Recebendo como entrada o sinal cardíaco (ECG - electrocardiograma), o dispositivo detecta a característica do sinal e, com base nessa característica, averigua se ocorreu alguma anomalia, produzindo um sinal de alarme se tal acontecer. O aparelho em causa tem que ser acessível, ter um baixo consumo energético, e a detecção de anomalias tem de ser efectuada em tempo real. Para que esta ultima condição se verificasse, o software implementado requer o mínimo de computação possível, de forma a efectuar todas as operações de detecção e análise num prazo limite de tempo, mantendo-se um detector fiável. O detector foi optimizado para uma frequência de entrada de 200Hz, e implementado em computador pessoal e num DSP (Digital Signal Processor – processador de sinal digital) desenvolvido pela Microchip. Ambas as implementações foram testadas recorrendo a sinais cardíacos fornecidos pela MIT-BIH Arrhythmia Database. Os testes desenvolvidos têm o propósito de testar a “qualidade” do detector e possíveis limitações do microprocessador usado, particularmente, no que diz respeito à capacidade de executar a detecção de anomalias cardíacas em tempo real. ABSTRACT: This project intends to produce a portable device for monitoring/analysis of cardiac activity. Receiving the cardiac signal (ECG – electrocardiogram) as input, the device detects the signal’s characteristics and, based upon those characteristics, checks whether some anomaly has occurred, producing an alarm signal in such case. The aforementioned device has to be affordable, low-power consumption, and the detection of anomalies has to be done in real-time. For this last condition to be verified, the implemented software requires as little computation as possible, so as to carry out all of the detection and analysis operations in a specified amount of time, while maintaining the characteristics of a reliable detector. The detector has been optimized for an input sampling frequency of 200Hz, and it has been implemented in a personal computer and in a DSP (Digital Signal Processor), developed by Microchip. Both implementations have been tested resorting to cardiac signals supplied by the MIT-BIH Arrhythmia Database. The tests that have been developed are designed to verify the quality of the detector, as well as possible limitations of the microprocessor used, particularly, when it comes to the ability to carry out the detection of cardiac anomalies in real-time.

kbasi September 2011, 99 pages As the trend to deeper mines continues, mine hoists and associated equipment will become more sophisticated, complex, large and expensive. Correct selection of the right type of hoist is imperative. In this vital link between underground and surface, crude estimates of hoist capacity are not good enough, and the mining engineer must design and select the right hoisting system to meet the design specifications and establish the most suitable operating parameters. This study aims to constitute a software model, which results all required design parameters of friction type winding system on minimum required power. The computer program has been structured on Microsoft Visual Basic programming language. The program requires user inputs (winding depth, hourly hoisting capacity) and selections (type and number of motors, type of friction wheel mounting) to run macros and equations so that the operating parameters such as skip capacity, rope type and diameter, hoisting speed, acceleration, cycle period, friction wheel diameter are determined to give the minimum motor power requirement.

Повний текст джерелаA les darreries del segle XX, l'auge de les aproximacions reduccionistes van permetre a la industria farmacèutica la recopilació de gran quantitat de informació, pero l’impacte en el rendiment de la producció de nous fàrmacs no va ser l’esperat. Encara que es van extreure moltes dades sobre les relacions un-a-un entre entitats sistèmiques els efectes complexos causats als sistemes biològics no es van poder adreçar adequadament. Aquesta tesi, desenvolupada en el marc d’una empresa biotecnolòica emergent, intenta introduir un marc de referència integral per l’aproximació sistèmica al disseny de fàrmacs. D'una banda, s’ha aplicat la predicció in silico de xarxes fàrmac-diana per identifcar les proteïnes relacionades amb càncer, per la construcció d’una biblioteca química d’amplia cobertura biològica i per anticipar la toxicitat relacionada amb dianes secundàries. D'altra banda, es va ampliar l’aproximació de biologia de sistemes per abastar les connexions anatòmiques. Aquesta nova metodologia fou dissenyada per complementar i assistir al toxicòleg expert en la identificació de toxicitats a nivell anatòmic. Finalment, durant aquests anys s’ha contribuit de manera important al desenvolupament d’una nova versió independent de la plataforma del programari estrella de l’empresa, CT-link, que n’ha facilitat enormement la seva distribució i comercialització.

Повний текст джерелаSelf-organization of living organisms is of an astonishing complexity and efficiency. More specifically, biological systems are the site of a huge number of very specific reactions thatrequire the right biomolecule to be at the right place, in the right order and in a reasonably short time to sustain cellular function and ultimately cellular life. From the dynamic point of view, this raises the fundamental question of how biomolecules effectively find their target(s); in other words, what kinds of forces bring all these specific cognate partners together in an environment as dense and ionized as cellular micro-environments. In the present thesis, we explore the possibility that biomolecules interact through long-range electromagnetic interactions as they are predicted from the first principles of physics; "long-range" meaning that the mentioned interactions are effective over distances much larger than the typical dimensions of the molecules involved (i.e., larger than about 50 angströms in biological systems).After laying the theoretical foundations about interactions that are potentially active over long distances in a biological context, we investigate the possibility of detecting their contribution from experimental devices which are nowadays available. On the latter point, encouraging preliminary results both at the theoretical and experimental levels are exposed
