Mary Georgi
Full text linkabstract: Mari Georgi left her village before it was attacked at the age of seven. She never witnessed the war but did hear about the attacks and the violence. On July 28, 2000 she came to the United States.
“Lost Boys Found” is an ongoing, interdisciplinary project that is collecting, recording and archiving the oral histories of the Lost Boys/Girls of Sudan. The collection is a work-in-progress, seeking to record the oral history of as many Lost Boys/Girls as are willing, and will be used in a future book.Age: 37Region: Southern SudanThis picture and bio was donated to the "Lost Boys Found" oral history project from The Arizona Lost Boys Cente

Vuk and Georgi: An adventure into active systems via mechatronics, robotics and manufacturing engineering
No full textDimirovski, Georgi M. (Dogus Author) -- Conference full title: 2013 IEEE 11th International Symposium on Intelligent Systems and Informatics (SISY) 26-28 Sept. 2013, Subotica, SerbiaThe last century's ending quarter was marked by an dramatically dynamic development of new technologies and practical realizations of diverse technical constructions in various fields of engineering, in general, and in robotics, in particular. However, such growth of new technological achievements was not accompanied always with the necessary caution steps and protection measures against possible breakdown and destructions, which in specific cases and under certain conditions could be disastrous. In this talk commemorating Academician Vukobratovic and drawing from his endeavors on the so-called active systems and research he shared with me as well as our academic cooperation during the last decade of his active work, while examining some advantages, his merits for the entire field are pointed in here out to the best author's abilities. Some active systems such as adaptation for active noise and machine vibration control via active damping by force feedback as well as mobile robotic unmanned air and underwater vehicles as well as platoon of ground vehicles are note considered. Rather focus is put on active controls of earthquake induced vibrations and high-rise structures, manufacturing processes, wheeled mobile manipulators and walking humanoid robots are discussed in more detail while on homing missiles are only mentioned. In due course, some solutions to contact task in dynamic environment that are linked with active systems are also touched upon
L-form transformation phenomenon in Mycobacterium tuberculosis associated with drug tolerance to ethambutol
No full textAbstractObjective/background: Cell wall-deficient bacterial forms (L-forms) may occur along with resistance to factors that trigger their appearance. It is of interest to study the relationship between the L-form transformation of Mycobacterium tuberculosis and the exhibition of drug tolerance to ethambutol (EMB), an inhibitor of cell wall synthesis. Methods: L-form variant was produced from a sensitive EMB strain of M. tuberculosis through a cryogenic stress treatment protocol and was subsequently cultivated in Middlebrook 7H9 semisolid medium, containing EMB in a minimal inhibitory concentration of 2mg/L. Susceptibility to EMB of the parental strain and its L-form variant was evaluated phenotypically and using polymerase chain reaction-restriction fragment length polymorphism assay targeting a mutation in the embB306 gene fragment. Results: In contrast to the sensitivity to EMB of the parental strain, its L-form variant showed phenotypic resistance to high concentrations of EMB (16mg/L), but the mutation in embB306 was not found. Electron microscopy observation of the L-form variant showed a heterogenic population of bacteria, with different degrees of cell wall deficiency, as well as cells of protoplastic type without cell walls. Of special interest were the observed capsule-like structures around the L-form cells and the biofilm-like matrix produced by the L-form population. Conclusion: We suggest that the expression of phenotypic resistance to EMB in M. tuberculosis can be associated with alterations or loss of cell walls in L-form bacteria, respectively, which results in a lack of a specific target for EMB action. In addition, production of capsule-like structures and biofilm matrix by L-forms could contribute to their resistance and survival in the presence of antibacterial agents

Passivity-based global stabilization of a class of switched nonlinear systems by backstepping
No full textDimirovski, Georgi M. (Dogus Author) -- Conference full title: 33rd Chinese Control Conference (CCC), 28-30 July 2014, Nanjing, ChinaThis paper considers the global stabilization problem for a class of switched nonlinear systems. Passivity-based global stabilization controller and a state-dependent switching law of switched nonlinear systems with any relative degree are designed with the help of the recursive feedback passification design technique. Finally, a numerical example is presented to illustrate the effectiveness of our results.IEE
Positive observer design for switched interval positive systems via the state-dependent and time-dependent switching
No full textDimirovski, Georgi M. (Dogus Author) -- Conference full title: 35th Chinese Control Conference: July, 2016, Chengdu, China.Positive observer design of interval switched positive systems is considered in this paper. The multiple quadratic co-positive Lyapunov functions technique and the method of augmented systems are adopted. The sufficient conditions of insuring stabilization of augmented systems are obtained under the state-dependent and time-dependent switching law, respectively. In the end, a numerical example is provided to demonstrate the feasibility of the presented results
