Aiming at the application of passive trackinn based on sensor array, a new passive trackinn usinn sensor array
based on particle filter was proposed. Firstly, the“fake points" could be almost entirely and exactly deleted with the aids of the
sensor array at the expense of an additional sensor. Secondly, considered the fact that the measurements notten from each array
were independent in passive trackinn system, a novel sequential particle filter usinn sensor array with improved distribution was proposed. At last, in a simulation study we compared this approach a壇orithm with traditional trackinn methods. The simulation re-sups show that the proposed method can nreatly improve the state estimation precision of sensor array passive trackinn system.
Parking Lot Simulation：
Parking lot attendants often park cars bumper-to-bumper, several cars deep. This maximizes the number of cars they can fit into a parking lot at the expense of complicating the process of retrieving someone s car when they want to leave. Consider the case of a person wanting to leave the parking lot but their car is parked in the back of a row of cars. In this case, all the cars parked in front of this person s car must be temporarily moved to allow this person to leave.
A major goal of this book is to show to make devices that are inherently reliable by design. While a lot of attention has been given to “quality improvement,” the majority of the emphasis has been placed on the processes that occur after the design of a product is complete. Design deficiencies are a significant problem, and can be exceedingly difficult to identify in the field. These types of quality problems can be addressed in the design phase with relatively little effort, and with far less expense than will be incurred later in the process. Unfortunately, there are many hardware designers and organizations that, for various reasons, do not understand the significance and expense of an unreliable design. The design methodology presented in this text is intended to address this problem.
Distributed applications, devices, and services appear in many different arrangements in an
enterprise. At your company, you probably access data from your intranet services, from
computers distributed throughout the company network, and from services across the firewall out
on the Web. For example, you might access a calendar-sharing application or a financial
application to fill out expense sheets. Someone must maintain all these applications. Not only the
applications, but also the hardware that supports them must be maintained. Resource management
encompasses both applications and hardware. In fact, both application and hardware management
can be supported through the development of Java Management Extensions (JMX) resource
management software. This book will show how you can use JMX to manage and monitor all
your resources across an enterprise—both software and hardware.
