Inverse methods in hydrogeology: Evolution and recent trends

Marine hydrogeology: recent accomplishments and future opportunities

Marine hydrogeology is a broad-ranging scientific discipline involving the exploration of fluid–rock interactions below the seafloor. Studies have been conducted at seafloor spreading centers, mid-plate locations, and in plateand continental-margin environments. Although many seafloor locations are remote, there are aspects of marine systems that make them uniquely suited for hydrologic analysi...

Recent Trends in Archaeological Theory: Some Comments

 This paper selectively reviews some recent themes in archaeological theory:  a philosophical pragmatism, a turn to materiality, and understanding the past in the context of the present.  It concludes with some reflective comments on the author’s Archaeological Theory:  An Introduction, in advance of the third revised edition.

Recent trends in methods of suicide.

Trends in completed suicide by method were analysed for Belgium between 1968-1972 and 1978-1981, using the information reported on death certificates. Around 1980, hanging was the most preferred method of suicide in both sexes, followed by firearms in males and poisoning by solid and liquid substances in females. Between 1970 and 1980, rates for all but one method (domestic gas) increased. The ...

Recent Advances in Digital Halftoning and Inverse Halftoning Methods

Halftoning is the rendition of continuous-tone pictures on displays, paper or other media that are capable of producing only two levels. In digital halftoning, we perform the gray scale to bilevel conversion digitally using software or hardware. In the last 3 decades, several algorithms have evolved for halftoning. Examples of algorithms include ordered dither, error diffusion, blue noise masks...
