Dr. Kanellakopoulos is a technology leader with 25+ years of experience in R&D and engineering management in both academia (former UCLA Professor of Electrical Engineering) and industry, and a seasoned expert witness with a perfect success record.
He has designed and built telecom products such as DSL and Carrier Ethernet hardware and software, as well as a prototype fully automated electric vehicle. He has conducted applied research in adaptive control of nonlinear systems, with applications to automotive driver assistance systems (adaptive cruise control, blind-spot monitoring, vehicle collision avoidance) and active suspensions. He has significant experience with international telecommunication standards (ITU-T SG15/Q4), and has directed collaborative projects with several automotive/truck manufacturers and vendors (Ford, Mercedes-Benz, DaimlerChrysler, Freightliner, Gentex, Visteon).
He has significant experience as an expert witness in patent infringement(including IPR) and product liability cases in the automotive and telecommunication areas; the vast majority of his cases have resulted in a win or a very favorable settlement for his clients. In 2017, he was the lead expert witness in a product liability case against Nissan that resulted in a $25M jury award for his clients; this decision was later upheld on appeal. His deep technical expertise allows him to analyze patents and products in detail, and explain clearly (in expert reports, depositions, and court testimony) the main issues that the judge and jury need to internalize in order to comprehend the essence of the case. His extensive educational experience allows him to help judges and jurors understand the topic they are dealing with, instead of confusing them with unnecessary technical details.
After all, it takes excellent teaching skills and a deep understanding of a complex technical concept to convey the essence of that concept to non-experts without talking down to them.
Using a pedagogical style along with detailed proofs and illustrative examples, this book opens a view to the largely unexplored area of nonlinear systems with uncertainties. The focus is on adaptive nonlinear control results introduced with the new recursive design methodology--adaptive backstepping. Describes basic tools for nonadaptive backstepping design with state and output feedbacks.
Abstract: A systematic procedure for the design of adaptive regulation and tracking schemes for a class of feedback linearizable nonlinear systems is developed. The coordinate-free geometric conditions, which characterize this class of systems, do not constrain the growth of the nonlinearities. Instead, they require that the nonlinear system be transformable into the so-called parametric-pure feedback form...

Recently, with the progress of computers, robot manipulators have obtained some abilities of perception and judgmenl. However, it st ill remains a dream that robots have the same or more nexible intelligence than humans. In the mean time, the physical ability of a robot manipulmor is superior in cases such as carrying heavy loads.
The primary Objective of the Berkeley lower Extremity Exoskeleton (BLEEX) Project at the University of California, Berkeley is to develop fundamental technologies associated with the design and control of energetically autonomous lower extremity exoskeletons that augment human strength and endurance during locomotion.

Geoffrey Beresford Hartwell is a Chartered Engineer who practices as an Arbitrator, Adjudicator and Expert for Determination. Geoffrey is the former Senior Partner of Consulting Mechanical and Electrical Engineers BHA Cromwell House.
A one time Chairman of the Expert Witness Society, Geoffrey Hartwell has experience giving evidence in court (in both civil and criminal matters) and in International Arbitration. He sometimes is retained as a Single Joint Expert or as a Tribunal Expert. His services are offered to both Plaintiff and Defense. Even when retained on behalf of a Client he, like all Experts, has an overriding responsibility to the Court or Tribunal.
After his early career in aerospace and nuclear energy, Geoffrey entered private practice in association with the late Leslie Heap and Gerald Lewis of Heap and Digby, Consulting Engineers, in 1969. While with them he designed water and sewage equipment and also the bascule moving machinery for the Lowestoft Bridge, in Suffolk. He practiced also as Beresford Hartwell and Associates and, in 1971 established a separate office in Wallington, South London.
In parallel with his design career, Geoffrey was first appointed as arbitrator in 1972 and his first foreign arbitration, an ICC appointment in Switzerland, took place later that year. He studied Law to Intermediate level and then transferred to the examinations of the Institute of Arbitrators (now Chartered) of which he became Chairman in 1996-1997 and for whom he taught in various countries on several courses, including the prestigious Diploma in International Commercial Arbitration.

He has been a member of Dispute Boards, retained from the beginning of a project or, alternatively, appointed on an ad hoc basis when a problem arises, Dispute Adjudication Boards to determine a binding decision, and on Dispute Review Boards to make decisions that are advisory but not binding.
Adjudication: Similar to arbitration, Mr. Hartwell adjudicates domestic and international disputes which are only temporarily binding unless otherwise agreed upon by the parties.
International Commercial Arbitration, the chosen basis of the annual Willem Vis Moot, is arguably not au fond a process at law. It is quite simply the performance of an agreement between two parties to have a chosen third party hear and determine some difference between them.
