Ioannis-Kanellakopoulos-Telecommunications-Expert-Photo.jpg
Dr. Kanellakopoulos is a technology leader with 25+ years of experience in R&D and engineering management in both academia and industry.

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).

His deep technical expertise in the areas of telecommunications and automotive driver assistance systems has allowed 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 comprehend in order to understand 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.
Ioannis Kanellakopoulos, PhD, et al
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.
Ioannis Kanellakopoulos, PhD
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...

William Pultar Human Factors Expert PhotoWilliam H. Pultar, BSME, ACTAR, is a Mechanical Engineer with over 20 years of experience in the field of Human Factors and Accident Reconstruction.

Background Experience - Employed by the Massachusetts State Police for several decades, Mr. Pultar's duties have included the investigation of line of duty injuries, citizen complaints, cruiser crashes, and the use of force incidents. As Section Supervisor for the Northeast Team of the C.A.R.S. unit, he was responsible for the training of the Northeast Team members in newer aspects of total station technology and was consulted numerous times on the kinematics of motor vehicle crashes by the Essex, Middlesex, and Hampshire District Attorney’s Offices.

Promoted to Lieutenant in 2010, Mr. Pultar was responsible and accountable for the supervision of A Troop personnel and the oversight of a geographical area that covers the northeast corner of Massachusetts and, as SCO, was put in charge of large high risk NIMS and crime related incidents such as the 2012 Beverly homicide and the Boston Bombing incidents.

Litigation Support - While employed by the Massachusetts State Police, Mr. Pultar testified numerous times in Federal District, Massachusetts Superior, and District Courts as an expert in the kinematics, kinetics of motor vehicle crashes, and human factors involving crashes, and as an expert in the electronic imaging of Crash Data Recorders. His services are available to counsel representing both Plaintiff and Defendant.

Areas of Expertise - William Pultar's expertise is in the Extraction of Electronic Data from Commercial Vehicle Engine Control Modules (CVEDM), motor vehicle crash data (CDR), restrain control module (RCM) and engine control modules (ECM) for all “supported vehicles. He currently has the only privately owned Hyundai and Kia download kits in New England. All of these modules are commonly referred to as vehicle “black boxes,” although they are NOT black boxes.

Mr. Pultar also specialized equipment to measure Luminance (NOT illumination), electronic survey crash scene, and measure acoustical data (sound energy), such as backup alarms, sirens, etc.
