This paper presents new decentralized optimal strategies for Cooperative Adaptive Cruise Control (CACC) of a car platoon under string-stability constraints. Two related scenarios are explored in the article: in the first one, a linear-quadratic regulator in the presence of measurable disturbances is synthesized, and the string-stability of the platoon is enforced over the controller's feedback and feedforward gains. In the second scenario, H 2 - and H ∞ -performance criteria, respectively accounting for the desired group behavior and the string-stability of the platoon, are simultaneously achieved using the recently-proposed compensator blending method. An analytical study of the impact of actuation/communication delays and uncertain model parameters on the stability of the multi-vehicle system, is also conducted. The theory is illustrated via numerical simulations.

AutoTechnology 2010年第1期10卷 46-50页

作者： Michailidis, Alexander Ringler, Thomas Hedenetz, Bernd Kowalewski, Stefan Department of E/E Architectures and Standards Group Research and Advanced Engineering Division Daimler AG Böblingen Germany Team E/E System Design and Applications Group Research and Advanced Engineering Division Daimler AG Böblingen Germany Software for Embedded Systems RWTH Aachen University Germany

The functionality of comfort and interior systems such as interior light, seat heating, central locking is typically distributed on several electronic Control Units (eCU). These systems very often consist of a central main function and many other smaller so-called client functions. The system or rather the eCU integration and thus the examination of the interplay of the functions with one another or with the hardware specific software is carried out in the right branch of the V-model according to the availability of the real eCUs. The construction of such models was up to now not practical due to the inconsistent eCU software architectures at the different suppliers. With the extensive adoption of the standardized Autosar software architecture and a consistent function-oriented Autosar SWC description, the design of virtual integration models in the earlier stages of development is for the first time possible with a reasonable effort.

作者： Scarfe, William C. In a recent e-mail exchange with a colleague my attention was drawn to an interesting Website (www. ***). Part of the site provides a list of idioms referred to as Langenberg's Laws that essentially pertain to business practices. At the time of writing there were 91 such “Laws” with the 100th already reserved. Many seem hauntingly familiar (eg “To err is human and some people are more human than others” - Langenberg's 80th Law). Reflecting on my appointment to Section Editor from a 2-year tenure as Associate Editor I was particularly struck with Langenberg's 5th Law: “If you want quality in the top 5% you have to filter through 20 and say no to the bottom 19.” So for this my first editorial I thought it appropriate to present prospective authors readers and referees my perspective on the role of specific constituents in the Peer Review Process. The rate of manuscript submissions to the OOOOE and the Radiology Section in particular over the past few years has increased dramatically. Commensurate with this greater demands have been placed on the peer review system and those who administer it – the Editorial Team. This comprises the editor-in-chief section editor associate editors editorial board and reviewers. Their activities are administratively facilitated by the supportive and knowledgeable Elsevier staff. With foresight Professor Allan G. Farman the previous Section Editor appointed Dr. Charles F. Hildebolt and myself as associate editors. Working together Charles and I have been able to assist in some administrative aspects of the Peer Review process for our Section. With my appointment I have retained Dr. Hildebolt and recruited Dr. Christos Angelopoulos at Columbia University College of Dental Medicine to assist me as associate editors. With an average rejection rate of approximately 70% many including those who have had submitted manuscripts rejected by our Section might view our role as simply applying Langenberg's 5th Law and envisage the Editorial Team as a “culling” mechan

Fuzzy system has been known to provide a framework for handling uncertainties and imprecision by taking linguistic information from human experts. However, difficulties arise in determining effectively the fuzzy system configuration, i.e. , the number of rules, input and output membership functions. A neuro-fuzzy system design methodology by combining neural network and fuzzy logic is developed in this paper to adaptively adjust the fuzzy membership functions and dynamically optimize the linguistic-fuzzy rules. The structure of a five-layer feedforward network is shown to determine systematically the correct fuzzy logic rules, tune optimally (in the sense of local region) the parameters of the membership functions, and perform accurately the fuzzy inference. It is shown both numerically and experimentally that engineering applications of the neuro-fuzzy system to vibration control have been very successful.

The impact of system issues on the performance and power rating of dynamics voltage restorers is examined. Algorithms to restore a network voltage sag or swell to given set points have been the subject of significant research in the past. The supervisory control scheme is examined to determine these set points. The control scheme's effect on device power rating (cost) and its interaction with active loads are investigated using analytical methods, simulation and experimental tests. The influence of the choice of the supervisory control algorithm on the selection of protection scheme and the interaction between the protection scheme and the device power rating are also examined.

While most of the theater ballistic missiles (TBM) in threat countries' inventories are of the shorter range SCUD varieties, mid- to long-range versions are currently in development in a number of third world countries. Threat potential exists in the following three battle spaces: endo-atmosphere (0-30 km), high endo-atmosphere (30-70 km) and exo-atmosphere (greater than 70 km). The inherent short range and low speed of endo-atmospheric threats match well with capabilities of SM-2 Block IVA, which equips the Navy with an area defense capability The exo-atmospheric TBMs are longer range and can threaten more targets which may be widely dispersed. Their higher velocities reduce response times dramatically Therefore, exo-atmospheric TBMs create the need for Standard Missile-3 (SM-3), which provides the Navy with theater wide defense capability. Defining its area and theater wide systems as clearly endo-atmospheric and exo-atmospheric systems allows the Navy to use derivatives of the Standard Missile Block IV to take full advantage of the conditions associated with each of these operating zones. Use of an existing missile and ship system baseline also allows use of the existing interface structure to minimize cost. To counter the endo-atmospheric TBMs, the SM-2 BLK TVA upgrades include an advanced imaging infrared (IIR) seeker, an improved fast-reaction auto pilot and a forward looking Re all in the same volume as the existing missile. The highly responsive SM-2 Block IVA missile, complemented with Aegis weapons systems modifications, provides capability against enemy aircraft and cruise missiles, as well as TBMs. Standard Missile-3 (SM-3) replaces the SM-2 Block TV warhead, radar and guidance section with a boosted third stage and an advanced kinetic warhead (KW). Operation in the exo-atmospheric region permits a KW design with autonomous guidance control and divert thrusters for high maneuverability and has the capability of achieving very high interceptor velocities.

The Navy's Sealift Program had several unique problems associated with it which have been addressed using innovative modeling and simulation tech niques. These techniques fall under two categories: visualization and dynamic analysis. This paper will discuss the employment of these techniques and the impact their application has had in the program. Also examined will be various difficulties that were encountered in the application of these techniques. Commercial-off-the-shelf (COTS) visualization tools were used to model the interior Ro/Ro spaces on the four classes of new construction and conversion ships now being procured. These models were employed for vehicle maneuvering simulations, operator familiarization and visualization of the results of an analysis of the loading and unloading of Ro/Ro vehicles. A COTS dynamic analysis system was used to simulate dynamic behavior during the assembly/deplopment and retrieval/disassembly of the side port ramp using the ships' cranes. These analyses supported reviews of design configurations, proposed handling procedures, and in conjunction with extensive post-processing, operability assessments for system operation. In a parallel effort, an interactive crane simulator was developed to support on-going engineering studies, indoctrination, and test and evaluation purposes. Lessons learned have been applied to other activities at the Naval Sea systems Command. Critical areas were the validation and maintenance of up-to-date configuration data for the visual models, adaptive levels of detail to meet the requirements of each study objective, and the need to provide comprehensive documentation of models.

This paper presents the design and realization of regenerative satellite on-board bypass test equipment. Furthermore, two particular examples of an in-orbit test transponder (IOTT) are discussed in detail. The IOTT1, developed for the first 30/20 GHz ITALSAT satellite (F1), was launched in January of 1991. IOTT1 has been a useful tool during satellite assembly, integration and pre-launch tests. IOTT1 was successfully used to fully characterize the multibeam ITALSAT satellite in orbit. In general, the IOTT functions to bypass the demodulator, the baseband switchboard and the modulator of the multibeam package of the ITALSAT spacecraft payload, providing the ability to fully characterize the satellite's transponders using well-established IOT test techniques. This paper describes and compares the design, fabrication and test of both ITALSAT in-orbit test RF bypass transponders (IOTT1 and IOTT2) mounted on board the ITALSAT multibeam spacecraft, (F1) and (F2), respectively. The IOTT1 contains the first MMIC circuitry ever launched into space on a communications satellite. The improved IOTT2, fabricated for the second 30/20 GHz ITALSAT satellite (F2), is schedule for launch in early 1996. These fully space-qualified designs incorporate COMSAT Laboratories' designed and fabricated MMIC K-u-band amplifiers, lightweight waveguide K-u-band channel filters and electronic power conditioner(ePC) and combined IOTT telemetry/command (T&C) circuitry.

Thermal desorption of PCB‐contaminated waste at the waukegan harbor superfund site

引用

Remediation Journal 1994年第2期4卷 207-222页

作者： Hutton, Joseph H. Shanks, Robert Joseph H. Hutton P.E. is the operations manager for SoilTech ATP Systems Inc. in Porter Indiana providing technical oversight project management and problem solving skills to applications of the SoilTech technology in soil treatment. Mr. Hutton's experience includes thermal treatment of soils industrial wastewater treatment system design startup and operation and application of process technology to in-situ soil and groundwater treatment. Robert Shanks is the technical supervisor for SoilTech supervising all technical aspects of SoilTech's thermal destruction system including technical direction of bench-scale testing and full-scale operations.

In June 1992, SoilTech ATP systems, Inc., completed the soil treatment phase of the Waukegan Harbor Superfund Project in Waukegan, Illinois, after approximately five months of operation. SoilTech successfully treated 12,700 tons of sediment contaminated with polychlorinated hiphenyls (PCBs) using a transportable SoilTech anaerobic thermal processor (ATP) system nominally rated at ten tons per hour throughput capacity. The SoilTech ATP technology anaerobically desorbs contaminants such as PCBs from solids and sludges at temperatures over 1,000° F. Principal products of the process are clean, treated solids and an oil condensate containing the hydrocarbon contaminants. At the Waukegan Harbor Superfund site, PCB concentrations in the sediments excavated and dredged from a ditch, lagoon, and harbor slip averaged 10,400 parts per million (ppm) (1.04 percent) and were as high as 23,000 ppm (2.3 percent). Treated soil was backfilled in an on‐site containment cell. The removal efficiency of PCBs from the soil averaged 99.98 percent, relative to the project performance specification of 97 percent, and treated soil PCB concentrations were measured below 2 ppm. Approximately 30,000 gallons of PCB oil, desorbed from the feed material, were returned to the owner for subsequent off‐site disposal. After modifications to the emissions control equipment, compliance with the 99.9999 percent destruction and removal efficiency (DRe) for PCBs in stack emissions required by the U.S. environmental Protection Agency was achieved.
