2.Introduction VLSI yield and quality measured as defect-level and fault coverage are important concepts related to electronic production and testing. [1] Both of defect-level and fault coverage are wildly used in today’s test field. For VLSI chips, it’s necessary for manufacturer to make the tradeoff between the test cost and high fault coverage. Some defect chips will be shipped to the market...

This paper describes Design Sheet, an advanced software system which facilitates the conceptual design of complex engineering systems. Design Sheet enables the designer to quickly explore large areas of design space and study how the different performance and cost criteria tradeoff with respect to one another. It provides an interactive interface for building analysis models in terms of systems...

Data deduplication has become a standard component in modern backup systems. In order to understand the fundamental tradeoffs in each of its design choices (such as prefetching and sampling), we disassemble data deduplication into a large N-dimensional parameter space. Each point in the space is of various parameter settings, and performs a tradeoff among backup and restore performance, memory ...

The Urban Rail Transit (URT) has been one of the major trip modes in cities worldwide. As the passengers arrive at variable rates in different time slots, e.g., rush and non-rush hours, the departure frequency at a site directly relates to perceived service quality of passengers; the high departure frequency, however, incurs more operation cost to URT. Therefore, a tradeoff between the interest...

Comparison of analog figures-of-merit of FinFETs and MOSFETs reveals an interesting tradeoff in the analog/RF design space. It is found that FinFETs possess the following key advantages over MOSFETs: reduced power dissipation, and better voltage gain without degradation of noise or linearity. This makes them attractive for low-frequency RF applications around 5 GHz, where the performance-power ...

Network intrusion detection systems (NIDS) make extensive use of regular expressions as attack signatures. Internally, NIDS represent and operate these signatures using finite automata. Existing representations of finite automata present a well-known time-space tradeoff: Deterministic automata (DFAs) provide fast matching but are memory intensive, while non-deterministic automata (NFAs) are spa...

This paper reports a study that challenges the widely-held assumption that security and functionality are a tradeoff relationship. Based on a survey sample of more than 9000 French firms, the study finds that higher degrees of system functionality entail higher degrees of security. Rather than sharing a tradeoff relation in which more security investments entail an opportunity cost in terms of ...

Most information security algorithms cannot achieve perfect security without incurring severe operational costs such as false alarms, network congestion, capital investment etc. Operating or designing an algorithm with perfect security is therefore not an economically rational alternative and thus the question arises of how to find the appropriate tradeoff between security and its costs. Althou...

In wireless ad hoc sensor networks, cooperation of nodes provides sensors with a broader range of information, often leading to an improvement in network’s ability to meet its global objectives. However, increased communication caused by cooperation leads to a cost-quality tradeoff in the network operation. We model the cooperation based on the range of its information sharing. In h-cooperation...

— This paper discusses the characteristics of a space-to-space multiple-input, multiple-output (MIMO) communication channel that distinguish it from more common terrestrial MIMO communication channels. These characteristics imply that the channel matrices for space communication channels have a particularly simple structure that leads to statistical characteristics that are both predictable and...
