This thesis relates the analysis of the full disk helioseismic data IRIS – International Research of the Interior of the Sun, running into multisite since 11 years. The merging of data from various partnerships in a coherent manner results in a significant improvement in duty cycles, initiating the IRIS++ network, whose data are from now on freely accessible. The long and short term variabilities of p-mode parameters with solar activity and frequency have been studied, thanks to the 11 years of collected measurements, covering a complete solar cycle. The observed variations in parameters show an important sensitivity with the activity, constraining the damping and the excitation of the modes during the solar cycle. The obviousness of variations about a few months in the p-mode frequencies is presented as well as the observation o similar periodicities to those found in other solar data set. Tables of frequencies and splittings have been computed

In infrastructure construction projects especially bridge investments, the most critical decisions that significantly affect the whole bridge LCC are the early stages decisions. Clearly, it's more beneficial to correctly choose the optimum bridge than to choose the optimum construction or repair method.
The ability of a bridge to provide service over time demands appropriate maintenance by the agency. Thus the investment decision should consider not only the initial activity that creates a public good, but also all future activities that will be required to keep that investment available to the public.
This research is aiming for bridge sustainability, enhance the bridge related decision making, and facilitate the usage of the bridge related feedbacks. The development of a reliable and usable computer tool for bridge LCC & LCA evaluation is the main target.
Toward the main goal, many steps were fulfilled. A unique integrated Bridge LCC evaluation methodology was developed. Two systematic evaluation ways were developed, one for bridge user cost and one for the bridge aesthetical and cultural value. To put these two systematic ways in practice, two preliminary computer programs were developed for this purpose. Today and future works are focusing on developing methodology and preliminary computer tool for bridge agency cost as well as the bridge LCA evaluation. KTH unique LCC evaluation system will enable the decision makers to correctly choose the optimum bridge in the early stages decision making phases as well as any later on reparation method.

understanding of acid-base concepts. Fifty- six tenth grade students from two classes of a chemistry course taught by the same teacher in Atatü
rk Anatolian High School 2003-2004 spring semester were enrolled in the study. The classes were randomly assigned as control and experimental groups. Students in the control group were instructed by traditionally designed chemistry instruction whereas students in the experimental group were taught by the instruction based on 5E learning cycle model. Acid-Base Concepts Achievement Test was administered to both groups as a pre-test and post-test in order to assess their understanding of concepts related to acid-base. Students were also given Attitude Scale Toward Chemistry as a School Subject at the beginning and end of the study to determine their attitudes and Science Process Skill Test at the beginning of the study to measure their science process skills. The hypotheses were tested by using analysis of covariance (ANCOVA) and t-test. The results indicated that instruction based on 5E learning cycle model caused a significantly better acquisition of scientific conceptions related to acid-base produced significantly higher positive attitudes toward chemistry as a school subject than the traditionally designed chemistry instruction. In addition, science process skill was a strong predictor in understanding the concepts related to acid-base.

Nowadays, the increase of risks associated with malaria results from the development of resistance of Plasmodium falciparum strains to antimalarial drugs. This situation and the lack of an effective vaccine require the development of new antimalarial strategies. Untilnow, molecular mechanisms controlling the life cycle of malaria parasites, are still poorly understood. In most eukaryotes, protein kinases are implicated in essential cellular functions and represent attractive targets for the development of new drugs. In this context, we focused on the signaling pathway implicating cAMP and particularly the catalytic subunit of cAMP-dependent protein kinase (PfPKAc), whose function is still unclear in P. falciparum. Two complementary strategies were chosen to study this kinase:1) at the biochemical level by the cloning, expression, purification and enzymatic characterization of the PfPKAc. The objective was to obtain an in vitro active PfPKAc to evaluate the kinetic constants of PfPKAc and to conduct the first inhibition studies.2) at the cellular level by studying the consequences of PfPKAc transcripts inhibition byspecific interfering RNAs. The parasite growth but also the overall transcriptome werestudied to specify the metabolic pathways associated with this plasmodial protein kinase.All of these studies improve the understanding of cAMP transduction pathway and PfPKA,which could allow the development of new therapeutic approaches

The TILC approach is analyzed by studying the closed-loop system in the discrete cycle domain through the use of the z-transform. The system, which has dynamic behaviour in the time domain, becomes a static linear mapping in the cycle domain. One can then apply on this equivalent system a traditional control approach, while considering that the system output is sampled once at the end of the cycle. On the other hand, from the standpoint of the real system, this control approach can be viewed as cycle-to-cycle control.
The stability and rate of convergence of the TILC algorithm can be analyzed through the location of the closed-loop system poles in the cycle domain. This analysis is relatively easy for a first-order TILC but becomes more complex for a higher-order TILC algorithm. The singular value decomposition (SVD) is used to simplify the convergence analysis while decoupling the system in the cycle domain. The SVD technique can be used to facilitate the design of higher-order TILC algorithms.
Internal Model Control (IMC) is another approach that can make the ILC design easier, because there is only one parameter per filter to adjust. The IMC technique has an interesting feature. In the case where the system is nominal, the closed-loop transfer function of the system is the same as the IMC filter's transfer function. Therefore, the adjustment of the filter parameter allows the designer to select the desired system response.
For industrial processes such as thermoforming ovens, it is important that the systems controlled by TILC algorithms are stable and have good performance. For thermoforming ovens, the terminal sheet temperature response must not be too oscillatory from cycle to cycle, since this may lead to high heater temperature setpoints. In the most serious case, high heater temperatures can cause the sheet to melt and spill on the heating elements at the bottom of the oven.
The performance aspect must not be neglected, since it is important to minimize the number of wasted plastic sheets, particularly at process startup. To avoid such waste of time and material, it is necessary that the TILC algorithm converge as quickly as possible. However, the robustness and performance objectives are conflicting and an acceptable compromise must be achieved. The control engineer must define specifications to describe these two constraints. Tools such as the Hinfinity Mixed-Sensitivity Analysis and mu-Analysis can be used to check the compliance of a given TILC algorithm with the robustness and performance specifications defined before the analysis. One can therefore compare various TILC algorithms quantitatively, through a computed measure obtained with one of the two approaches. These same tools can be used for the design of TILC algorithms, using weighting functions representing the specifications.
Simulation and experimental results obtained on industrial thermoforming machines show the effectiveness of the various approaches in this thesis. Many examples are also presented throughout the chapters.

mathematics achievement on and attitudes toward mathematics. The study was carried out in a public school in one of the towns of the Central Anatolia Region with 28 sixth-grade elementary school students. One group pretest-posttest design was used. Mathematics Achievement Test and Mathematics Attitude Scale were administered to collect the necessary data. The instruction will be applied by the researcher five hours per week in a 15-week. The data were analyzed by using one-way repeated measures analysis of variance and a paired-samples t-test. According to the results of the study it was found that there was a statistically significant change in mathematics achievement of sixth grade students who participated in the instruction based on 5E learning cycle over three time periods (pre-intervention, post-intervention, and follow-up). There was only no statistically significant mean difference between post-intervention and follow-up mathematics achievement. Furthermore, there was a statistically significant decrease in mean scores of attitudes toward mathematics from prior intervention to after intervention.

This dissertation describes the most comprehensive study to date of the diurnal cycle of air pollution in the Kathmandu Valley, Nepal -- a bowl-shaped mountain valley of two million people with a growing air pollution problem but little past research. Field measurements and computer simulations were used to study the interplay of emissions and ventilation. From September 2004 through June 2005, CO (carbon monoxide), ozone, PM10 (particles smaller than 10 micrometers), wind speed and direction, solar radiation, temperature, and humidity were continuously measured east of Kathmandu. Sensors towers and mountains measured the diurnal cycle of the vertical temperature structure and stability. A sodar measured the mixed layer height and upper-level winds. Bag sampling provided the diurnal cycle of CO on mountains, passes and around the valley. Winds were measured on a mountain pass and ozone on a mountaintop. Patterns of air pollution and meteorology in the valley showed remarkable day-to-day similarity, with daily twin peaks of CO and PM10, a noon ozone maximum, afternoon westerly winds, and a stagnant cold pool at night. On mountaintops at night, ozone remained high, while CO dropped to regional background levels.
(cont.) The meso-scale meteorological model MM5 was adapted to the Kathmandu Valley for days in February and May 2005. It was able to capture the essential features of the valley's meteorology and was used to address three specific questions: The break-up of the valley's temperature inversion was found to be dominated in February by up-slope winds on the valley rim, plus subsidence over the valley center; in May surface heating of the valley bottom also played a major role. The pathways of pollutant transport out of the valley were found to be up the valley rim slopes in the morning, but out the eastern and southern passes in the afternoons. At night pollutants remained within the valley except near the river outlet. They were lifted off the ground at night and re-circulated in the morning. The eulerian chemistry transport model CAMx, was used in tracer mode, with MM5 meteorology to simulate the emission, transport and removal of CO from the Kathmandu Valley. The simulations were limited by the accuracy of Kathmandu's emissions inventory, especially the spatial distribution of emissions.
