Ernest Sosa has long defended bi-level virtue epistemology on the grounds that it offers the best overall treatment of epistemology’s central issues. A surprising number of problems “yield to” the approach (Sosa 1991: 9). Sosa applies bi-level virtue epistemology to diagnose and bypass ongoing disputes in contemporary epistemology, including the disputes between foundationalists and coherentist...

This paper presents a new decoding method of redundant residue polynomial codes. The decoding method has an advantage of correcting errors easily by checking the degree of the product of a polynomial corresponding to a received code and the moduli corresponding to error positions. The number of operations needed fbr this decoding method is about 1/10-11100 tirnes as Iarge as that needed fbr the...

1. Introduction In the course of researching information about a new topic, people often consult many sources of information. These sources may be available in various forms such as web pages, word processor files, and spreadsheets. Frequently, individual sources contain more information than people need. In such cases, people excerpt just the information they need. Also, they annotate existing...

The discovery of multiband afterglows definitely shows that most γ-ray bursts are of cosmological origin. γ-ray bursts are found to be one of the most violent explosive phenomena in the Universe, in which astonishing ultra-relativistic motions are involved. In this article, the multiband observational characteristics of γ-ray bursts and their afterglows are briefly reviewed. The standard model ...

In-network data aggregation is considered an effective technique for conserving energy communication in wireless sensor networks. It consists in eliminating the inherent redundancy in raw data collected from the sensor nodes. Prior works on data aggregation protocols have focused on the measurement data redundancy. In this paper, our goal in addition of reducing measures redundancy is to identi...

In this paper, we present the design, fabrication and characterization of a novel gas microvalve realized by combining microand fine-machining techniques. The design is for high flow rates at high pressure difference between inlet and outlet, burst pressure of up to 15 bars. There is no power consumption required for the valve to maintain its position during operation in any intermediate state ...

We show that the re-brightening in the GRB 021004 optical afterglow light curve around ∼ 0.1 day can be explained within the framework of the standard fireball model. The superposition of a forward and reverse shock emissions result in the peculiar behavior. With the standard values of parameters obtained in other afterglow observations, we can construct an example case in which theoretical est...

Presently, tree coders are the best bi-level image coders. The current IS0 standard, JBIG, is a good example. By organising code length calculations properly a vast number of possibie models (trees) can be investigated within reasonable time prior to generating code. Three general-purpose coders are constructed by this principle. A multi-pass free tree coding scheme produces superior compressio...

A new technique, Bi-Level Weighted Histogram Equalization (BWHE) is proposed in this paper for the purpose of better brightness preservation and contrast enhancement of any input image. This technique applies bi-level weighting procedure on Brightness preserving Bi-Histogram Equalization (BBHE) to enhance the input images. The core idea of this method is to first segment the histogram of the in...

In this paper we consider hierarchically decomposed multilevel systems, and extend previous deterministic methodologies for optimal and consistent design of such systems to account for the presence of uncertainties. Specifically, we use the probabilistic formulation of the analytical target cascading process to solve the multilevel problem, and use an advanced mean value-based technique to esti...
