Position and Trajectory Control of a Quadcopter Using PID and LQ Controllers

This thesis describes the work done to implement and develop position and trajectory control of a quadcopter. The quadcopter was originally equipped with sensors and software to estimate and control the quadcopter's orientation, but did not estimate the current position. A GPS module, GPS antenna and a LIDAR have been added to measure the position in three dimensions. Filters have been implemented and developed to estimate the position, velocity and acceleration. Four controllers have been designed that use these estimates: one PID controller and one LQ controller for vertical movement, and a position controller and a trajectory controller for horizontal movement. The position controller maintains a constant position, while the trajectory controller maintains a constant velocity while travelling along a straight line. These position and trajectory controllers calculate the reference angles required to direct the thrust necessary to control the quadcopter's movement. Additionally, an algorithm has been developed to decrease overshoot by predicting future trajectories. These controllers have proven to be successful at controlling the quadcopter's position in all three dimensions, both in practice during outdoor flight and in simulations.

Faculty Opinions recommendation of Absence of effects of Sir2 overexpression on lifespan in C. elegans and Drosophila.

Overexpression of sirtuins (NAD(+)-dependent protein deacetylases) has been reported to increase lifespan in budding yeast (Saccharomyces cerevisiae), Caenorhabditis elegans and Drosophila melanogaster. Studies of the effects of genes on ageing are vulnerable to confounding effects of genetic background. Here we re-examined the reported effects of sirtuin overexpression on ageing and found that standardization of genetic background and the use of appropriate controls abolished the apparent effects in both C. elegans and Drosophila. In C. elegans, outcrossing of a line with high-level sir-2.1 overexpression abrogated the longevity increase, but did not abrogate sir-2.1 overexpression. Instead, longevity co-segregated with a second-site mutation affecting sensory neurons. Outcrossing of a line with low-copy-number sir-2.1 overexpression also abrogated longevity. A Drosophila strain with ubiquitous overexpression of dSir2 using the UAS-GAL4 system was long-lived relative to wild-type controls, as previously reported, but was not long-lived relative to the appropriate transgenic controls, and nor was a new line with stronger overexpression of dSir2. These findings underscore the importance of controlling for genetic background and for the mutagenic effects of transgene insertions in studies of genetic effects on lifespan. The life-extending effect of dietary restriction on ageing in Drosophila has also been reported to be dSir2 dependent. We found that dietary restriction increased fly lifespan independently of dSir2. Our findings do not rule out a role for sirtuins in determination of metazoan lifespan, but they do cast doubt on the robustness of the previously reported effects of sirtuins on lifespan in C. elegans and Drosophila.© 2011 Macmillan Publishers Limited.

Early Restoration of Autotransplanted Pituitary Function as Determined by Plasma Progesterone Concentrations

Levels of peripheral blood progesterone weremeasured in rats hypophysectomized and autografted on the day of sperm detection (day 1 of pregnancy) and sacrificed at 24 h intervals over a period of 10 days. After an initial delay, progesterone levels reached 3.43 ± 0.80 µg/100 ml at 48 h after autografting, which is comparable to the value on day 6 of normal pregnancy. Progesterone titres reached a level of 8.46 ± 0.98 µg/100 ml by the 6th day of transplantation and showed no significant change for the duration of the experiment. Although rats were pregnant at the time of autografting, only resorbing implantation sites were noted in some of the rats at autopsy. The results of this study indicate that an ectopically placed pituitary achieves functional restitution within 24 to 48 h following transplantation. Although progesterone levels were equal to or greater than those found in normal pregnancy, the transplanted pituitary per se was unable to maintain pregnancy.

Radiation risk management at DOE accelerator facilities

The DOE accelerator contractors have been discussing among themselves and with the Department how to improve radiation safety risk management. This activity-how to assure prevention of unplanned high exposures-is separate from normal exposure management, which historically has been quite successful. The ad-hoc Committee on the Accelerator Safety Order and Guidance [CASOG], formed by the Accelerator Section of the HPS, has proposed a risk- based approach, which will be discussed. Concepts involved are risk quantification and comparison (including with non-radiation risk), passive and active (reacting) protection systems, and probabilistic analysis. Different models of risk management will be presented, and the changing regulatory environment will also be discussed..

Evaluating the Risk of Hypertension in Residents in Primary Care in Shanghai, China with Machine Learning Algorithms

Abstract The prevention of hypertension in primary care requires an effective and suitable hypertension risk assessment model. The aim of this study was to develop and compare the performances of three machine learning algorithms in predicting the risk of hypertension for residents in primary care in Shanghai, China. A dataset of 40,261 subjects over the age of 35 years was extracted from Electronic Healthcare Records of 47 community health centres from 2017 to 2019 in the Pudong district of Shanghai. The XGBoost model outperformed the other two models and achieved an AUC of 0.765 in the testing set. Twenty features were selected to construct the model, including age, diabetes status, urinary protein, BMI, elderly health self-assessment, creatinine, systolic blood pressure of the upper right arm, waist circumference, smoking status, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, frequency of drinking, glucose, urea nitrogen, total cholesterol, diastolic blood pressure of the upper right arm, exercise frequency, time spent engaged in exercise, high salt consumption, and triglycerides. XGBoost outperformed random forest and logistic regression in predicting the risk of hypertension in primary care. Integration of such a risk assessment model into primary care may improve the prevention and management of hypertension in residents.

The Potential of<i>grxB</i>Gene for Detection of<i>C. sakazakii</i>in Infant Formula Milk Using Real-Time Polymerase Chain Reaction

Cronobacter sakazakii is one of the bacteria that causes food poisoning that contaminates infant formula. This pathogen causes necrotizing enterocolitis, sepsis, and meningitis in infants or neonates with reported case fatality rates ranging from 40% to 80%. Therefore, it is necessary to develop fast and accurate detection of C. sakazakii in infant formula milk. This research aims to develop a method for detecting C. sakazakii bacteria using real-time PCR with high sensitivity, specificity, and accuracy. A rapid detection method using real-time PCR with the target gene grxB successfully detects the presence of C. sakazakii DNA in artificially contaminated formula milk. The results of the real-time PCR test showed that C. sakazakii DNA with a concentration of 53 ng/µL could be amplified by the grxB gene primer pair with a Ct value of 12 and a Tm value of 85.8ºC. The specificity test showed that the grxB primer could differentiate between target and some non-target bacteria. The sensitivity test showed the ability of the grxB primer to detect the smallest concentration of 3,392 pg/µL with a Ct of 24,06. Based on the results obtained, it can be concluded that the grxB primer has the potential to be used as rapid detection method for C. sakazakii bacteria in infant formula using real-time PCR.

Learner Achievement Effect of the Multiple Intelligences Theory Based Teaching in the Unit of Whole Numbers at the Primary Education Seventh Grade Mathematics Course

The only way to be able to succeed in mathematics is to understand its nature. If you cannot discover the beauty of mathematics and make students curious about it, mathematics education may not be realized. The aim of mathematics must be solving to learn, not learning to solve. It is not possible to convince students that “mathematics is joyful” before they are made a part of it. Multiple Intelligences Theory may be useful to realize this part of mathematical charasteristics. Mathematics has relationships with other disciplines as well as abstract discussion inside. In this study, the effect of the application of Multiple Intelligences Theory upon the learning process is investigated. Success in mathematics is compared by “Whole Numbers Knowledge Scale”. After the statistical analyses it was seen that througout the application process, there has been important diMatematik Öğretimi, Çoklu Zeka TeorisiMathematics Teaching, Intelligence, Multiple Intelligences Theory Tam Metin

Si surface passivation by Al2O3 thin films deposited using a low thermal budget atomic layer deposition process

High-quality surface passivation of crystalline Si is achieved using 10 nm thick Al2O3 films fabricated by thermal atomic layer deposition at 100 °C. After a 5 min post deposition annealing at 200 °C, the effective carrier lifetime is 1 ms, indicating a functional level of surface passivation. The interplay between the chemical and the field effect passivation is investigated monitoring the density of interface traps and the amount of fixed charges with conductance-voltage and capacitance-voltage techniques. The physical mechanisms underlying the surface passivation are described. The combination of low processing temperatures, thin layers, and good passivation properties facilitate a technology for low-temperature solar cells.

Urinary calcium creatinine ratio and hypercalciuria.

Random urine samples of 352 children in the age group of 5-12 yrs were studied for urinary calcium-creatinine ratio (Uca/Ucr mg/mg). None had any predisposing factor for secondary hypercalciuria. Calcium and creatinine both were estimated by colorimetric method. We observed that Uca/Ucr in the general pediatric population was skewed, the pattern was similar to that described in western children and it was independent of age and sex. The mean and standard deviation (SD) of Uca/Ucr was 0.10 +/- 0.094. Considering mean +2SD as the upper limit of normal, which was 0.29 in this series, the prevalence of hypercalciuria was 6.5%.

A Life Course Perspective in the Analysis of Self-Experiences of Female Migrants in Belgium: the Case of Ukrainian and Russian Women in Belgium

This study analyzes how migration transforms experiences of the self in Russian and Ukrainian women in Belgium, from a retrospective life course perspective. The author particularly focuses on gender identities in interaction with other aspects of the self such as educational and professional background, nationality and legal status. She aims both to highlight variation in gendered responses between Russian and Ukrainian women (inter-subjective variation), and within Russian and Ukrainian women (intra-subjective variation) over time and in two life domains (family and the labour market). The present analysis draws on the transversal analysis of the FEMIGRIN-project, a Belgian science policy project on female migration that cross-compared 5 case studies of female migrants in Belgium. The results of this transversal analysis were grouped in the construction of several “characteristic” migration trajectories of female migrants in Belgium. The present article reconstructs these trajectories with the qualitative data of the Russian and Ukrainian case study, from a life course and intersectional theory perspective. The combined life course and intersectional research perspective enabled the author to study how personal goals, aspirations and experiences of the self are continuously interpreted and re-interpreted in the course of migration, in interaction with the surrounding environment. Since women’s migration life courses develop largely according to their legal status and migration type, the author can conclude that female migrants’ opportunities and constraints are highly determined by these social categories. The analysis reveals that women’s life courses seem to be less structured by the investment of individual level capacities than by policy determined categories.

Terrorist Incidents against Jewish Communities and Israeli Citizens Abroad 1968–2010

Terrorism against Jewish communities
and Israeli targets abroad represents
the most violent aspect of
contemporary antisemitism, and the
greatest physical danger to Diaspora
Jewish communities. Antisemitic
conspiracy theory, extremist ideology
and irrational hatred combine with the
rational calculations of political violence
to threaten the lives of ordinary Jews
and others all over the world. This
ongoing terrorist threat to Jews
demonstrates in the starkest terms
why Jewish communities require
security at their synagogues, schools
and community buildings, and that an
attack on a Diaspora Jewish community
is also an attack on the state and its
capacity to protect its citizens.
Terrorist Incidents Against Jewish
Communities and Israelis Abroad
catalogues 427 terrorist attacks and
plots, including those which were foiled
by police or aborted by the plotters,
which targeted Jews or Israelis outside
Israel between 1968 and 2010. It
includes attacks and plots by neo-Nazis,
Marxist-Leninists, anarchists, Palestinian
and other Arab nationalists,
revolutionary Iran and its surrogates
and radical Sunni Islamists. The first
edition of this book, which was published
in 2003 by CST and the Institute for
Counter-Terrorism in Herzliya, Israel,
was the first time that this history of
post-1967 anti-Jewish terrorism had
been comprehensively collated. This
edition includes an updated chronology
of attacks, an expanded analysis and
new statistical tables.

Seamless control of distributed multi-converter system with high power quality

Robust control of inverter-interfaced distributed energy resource (DER) in a smart distribution grid is essential in order to facilitate flexibility of the grid. This paper presents a control structure for multi-converter system based on direct-current control and dynamic power sharing at the point of common coupling (PCC). The system includes two voltage source converters (VSCs) for grid interface of DERs and the active damping controller in the voltage control which is provided by the converter-interfaced load (CIL) for effective rejection of disturbances. On the other hand, wide band voltage control loop in both grid-connected and islanded modes is designed to improve the dynamic response of the system featuring power quality (PQ) improvement. The proposed scheme addresses a robust controller against interaction dynamics between active damping and current tracking controller in the presence of grid induced disturbances. (4 pages)

Entalpy of Mixing, Microstructure, Structural, Thermomagnetic and Mechanical Properties of Binary Gd-Pb Alloys

The aim of the present work is to study the phase composition, microstructure and magnetocaloric effect of binary Gd100−xPbx (where x = 5, 10, 15 and 20) alloys. The XRD and SEM/EDX analysis confirmed a biphasic structure built by Gd(Pb) and Gd5Pb3 phases. The analysis of M vs. T curves showed the evolution of the Curie point of recognized phases. The temperature dependences of magnetic entropy change revealed two maxima corresponding to the recognized phases. The analysis of the exponent n (ΔSMmax = C(Bmax)n) confirmed the multiphase composition of the produced alloys. The same behavior was also observed in investigations of mechanical properties.

<i>KymographClear</i> and <i>KymographDirect</i>: two tools for the automated quantitative analysis of molecular and cellular dynamics using kymographs

Dynamic processes are ubiquitous and essential in living cells. To properly understand these processes, it is imperative to measure them in a time-dependent way and analyze the resulting data quantitatively, preferably with automated tools. Kymographs are single images that represent the motion of dynamic processes and are widely used in live-cell imaging. Although they contain the full range of dynamics, it is not straightforward to extract this quantitative information in a reliable way. Here we present two complementary, publicly available software tools, KymographClear and KymographDirect, that have the power to reveal detailed insight in dynamic processes. KymographClear is a macro toolset for ImageJ to generate kymographs that provides automatic color coding of the different directions of movement. KymographDirect is a stand-alone tool to extract quantitative information from kymographs obtained from a wide range of dynamic processes in an automated way, with high accuracy and reliability. We discuss the concepts behind these software tools, validate them using simulated data, and test them on experimental data. We show that these tools can be used to extract motility parameters from a diverse set of cell-biological experiments in an automated and user-friendly way.
