1. An approach to design feedback controllers for flight control systems employing the concepts of gain scheduling and optimization.
The role of feedback in the design of aircraft stability and control is becoming increasingly important. The basic reason driving this trend is the necessity to cope with a growing number of more stringent requirements, which are sometimes conflicting. This work presents a design methodology applicable to flight control laws, which can be either a control an

2. Reduction of structural vibration induced by solar array drive mechanisms using input shaping control techniques / Redução de vibrações estruturais induzidas pelo mecanismo de acionamento da asa de painéis solares, usando a técnica de formatação do sinal de entrada
The input shaping technique was employed in this work to reduce the vibration effect at a flexible beam, caused by a step motor actuator. The technique is based on the cancellation of poles of the system by allocating zeros on or near poles. The switching sequence of the step motor was designed in a strategic way so that the vibration produced by the train o

3. Redução de vibrações estruturais induzidas pelo mecanismo de acionamento da asa de painéis solares, usando a técnica de formatação do sinal de entrada / Reduction of structural vibration induced by solar array drive mechanisms using input shaping control techniques
A técnica de formatação do sinal de entrada foi empregada nesse trabalho para minimizar os efeitos vibratórios sobre uma viga flexível, causados por um atuador tipo motor de passo. A técnica é baseada no cancelamento de pólos do sistema, alocando-se zeros sobre ou próximos aos pólos. A seqüência de acionamento do motor de passo foi projetada de f

4. Analysis and synthesis of robust control system with separable nonlinearities.
The objective of this thesis is to propose a design method for controllers to secure specified robust oscillation amplitude and frequency for separable nonlinear systems exhibiting unavoidable or desirable limit cycles. The design approach of robust limit cycle controllers introduced here can be used for autonomous systems with separable single-input-single-

5. Conducting an assessment of health needs and resources in a racial/ethnic minority community.
This article examines strategies and methodologic issues for researchers to consider when conducting community-based research within a racial/ethnic minority community. Members of minority communities have considerable skepticism about the health care system and researchers who work under its auspices. To facilitate quality research, it is necessary to build

6. Founding Mothers of Jewish Communities: Geographically Separated Jewish Groups Were Independently Founded by Very Few Female Ancestors
We have analyzed the maternally inherited mitochondrial DNA from each of nine geographically separated Jewish groups, eight non-Jewish host populations, and an Israeli Arab/Palestinian population, and we have compared the differences found in Jews and non-Jews with those found using Y-chromosome data that were obtained, in most cases, from the same populatio

7. Post-synaptic inhibition of bulbar inspiratory neurones in the cat.
Stable intracellular recordings from thirty-six bulbar inspiratory neurones revealed three centrally originating, rhythmic patterns of synaptic inhibition (i.p.s.p.s). (i) A declining pattern of i.p.s.p.s accompanying the early stages of inspiration (early inspiratory inhibition) was identified in a total of twenty neurones representing examples of each of t
