Talk Title: Therapeutic Ultrasound Applications in the Human Brain - From Noninvasive Surgery to Local Drug Delivery
Abstract: Despite its initial purpose of being a purely diagnostic tool the knowledge of ultrasound induced biomechanisms increased rapidly during the last years, changing significantly the scope of how ultrasound might be used in the future. Noninvasive surgery and local drug delivery became major research developments in the field of therapeutic ultrasound in the brain. Image-guided therapy using ultrasound, temporary opening of the blood-brain barrier, local drug delivery using acoustically active carriers or the controlled induction of cell modulations are major topics of current therapeutic ultrasound research activities. Besides conventional ultrasound techniques the development of high intensity focused ultrasound (HIFU) systems broadened the variety of potential applications significantly, including brain tumor treatment, stroke, neurodegenerative diseases or neuromodulation.
The rapidly increasing knowledge of disease mechanisms and progressing development in medical device technologies, such as ultrasound, provide new insights of how diseases might be treated in the near future. The activities in the field of therapeutic ultrasound are research areas at the interface of engineering and biomedical sciences with the highest future potential.
The presentation will give an overview of some of these applications using different ultrasound approaches and will provide an inside of current research activities in this field at the UCSD Brain Ultrasound Research Laboratory.

Speaker: Dr. Daniel P. Raymer, President, Conceptual Research Corp.
Talk Title: Design and Analysis of Hybrid Airships
Abstract: Dan Raymer will discuss the design and analysis of hybrid airships. Raymer performed the initial design and analysis of the Ohio Airship "Dynalifter", a hybrid flight vehicle combining hydrostatic lift from helium with aerodynamic lift from wings and a shaped hull. This concept avoids many of the problems of traditional airships since a large fraction of its weight is carried by aerodynamic lift. It lands like a normal aircraft, decelerating on a runway as its weight is transferred from the wings to the tires. It has substantial weight on its tires when sitting on the ground allowing it to withstand a gusty side wind. Compared to a normal aircraft, the dynamic lift airship has reduced drag when flown at low speeds and flies on much less power than a conventional aircraft carrying a similar payload. Raymer will discuss the advantages of such designs, how such design differs from normal aircraft design practice, and factors that influence the likely success of such projects.

Talk Title: An Approach to Control of Dynamic Systems with Multiple Objectives
Abstract: The challenges of controlling dynamic systems with multiple objectives are related to and furthermore include problems in multi-player dynamic games, multiobjective optimization, and decentralized control and estimation which all are known to be independently difficult and unsolved in general terms. The additional complexity is introduced through nonlinear dynamic models with delays and perturbations as well as various state, input and communication constraints. In this talk we will present a number of recent results in control of dynamic systems with multiple objectives based on a Liapunov-like approach as well as differentiable approximations of minimum and maximum and differential inequalities. We will show simulations of multi- vehicle systems achieving multiple objectives such as collision avoidance, trajectory tracking, control of formations of vehicles, and surveillance of compact domains. In addition a number of experimental results including autonomous and semi-autonomous (that is, teleoperated) ground vehicles (conducted in the Robotics Laboratory at the University of Illinois) and aerial vehicles (conducted at the Boeing Company in Seattle) will be presented.

Talk Title: The Seven Deadly Sins of Aircraft Design
Abstract: This presentation examines mistakes that occur regularly in airplane design. The designs that result from these missteps fail. The failures can be technical, leading to machines that refuse to fly or are never completed. The failure can also be one of effectiveness; the aircraft is technically successful as a flying machine, but is economically unviable or unable to perform its mission. The goal of the presentation is to describe the most common of these failure types and to provide, through historical example, insight enabling recognition and avoidance of the most common traps early in the design process.
Biography: Mr. Barnaby Wainfan is Technical Fellow for Aerodynamics Design at Northrop Grumman Corporation.

Talk Title: 25 Years of Adaptive Structures â A Subjective Perspective
Abstract: While âsmart materials,â particularly piezoelectrics, have been known and used by the scientific community for more than a century, the term âsmart structuresâ came into vogue in the 1980s. The impetus for the research at that time was sparked by the initial demonstration of embedded fiber optic sensors in a composite laminate. Since then, hundreds of millions of dollars of R&D investment has been made in the broad area of smart or multi-functional materials and structures. This presentation traces the historical development of this field, starting from about the mid-80s to the present, in three areas:
1. Health monitoring, mainly for structures, wherein sensors are attached or embedded in the structures to monitor its (internal) health, to increase safety, reliability and possibly increase the flight envelope;
2. Integration of antennas and other sensors to provide multi-function capabilities at the component level â for instance provide optimal structural and antenna performance, enhancing overall system capability;
3. Adaptive structures where sensors and actuators are integrated in the structure or the overall system to change shape or state to optimize its performance for differing external conditions such as loads and flight regimes. The rationale in this case is to provide multi-point optimization at the system level, for example to realize wing shapes which could be optimal across a wide speed range, resulting in multi-mission capabilities.
While much fundamental and applied research has been conducted in all three areas, transition of the developed technologies with demonstrated performance improvements has been limited. The reasons for this are many and varied; the presentation provides a broad brush, subjective, assessment of the overall R&D commercialization efforts in the field and a speculative vision of the future of smart structures.
