This paper describes a procedure for the simulation of passive filters using switched-current techniques, where sensitivity reduction is obtained by swapping the positions and roles of pairs of identical elements at successive switching periods. The technique can produce significant reduction of sensitivity to element mismatches at low cost in terms of added complexity and without reducing the ...

Recent research has increasingly examined customer switching costs in regards to antecedents and relational outcomes. This study extends current research by testing a framework for understanding the underlying relationships between perceived service quality, switching costs, and customer satisfaction with a service provider. The findings of this study suggest that there is a significant and pos...

A two-way tactile communication system incorporating oral-based tactile modes is developed. The prototype system allows the user to both receive navigation cues, via a microfabricated flexible electrotactile palate display, and transmit information to the outside environment using a tongue operated device (TOD). The palate display consists of a flexible electrocutaneous-mode 7x7 electrode array...

In a distributed environment where nodes are independently motivated, many transactions or commercial exchanges may be stymied due to a lack of trust between the participants. The addition of trusted intermediaries may facilitate some exchanges, but others are still problematic. We introduce a language for specifying these commercial exchange problems, and sequencing graphs, a formalism for det...

Firm turnover (i.e. firm entry and exit) is a well-recognized source of sectorlevel productivity growth across developing and developed countries. In contrast, the role and importance of firms switching activities from one sector to another is little understood. Firm switchers are likely to be unique both from newly established entrants and exiting firms that close down. We build an empirical m...

This paper is a tutorial review of some former and recent work in classification of switching functions. Considered are different approaches to the classification and discussed features of resulting classification methods.

In this paper, we provide a model-free test for asymmetric correlations which suggest stocks tend to have greater correlations with the market when the market goes down than when it goes up. In addition, we evaluate the economic significance of asymmetric correlations by answering the question that what is the utility gain for an investor who switches from a belief of symmetric correlations int...

Many researchers show that “market institutions” are an ideal means to exchange and allocate resources under the assumptions of perfect and symmetric information and perfect competition. However, in the real world, we observe many instances in which these assumptions are not satisfied due to imperfect competition, incomplete information, transaction costs, and externalities. In this study we fo...
