Kilim: A Server Framework with Lightweight Actors, Isolation Types & Zero-copy Messaging Sriram Srinivasan Internet services are implemented as hierarchical aggregates of communicating components: networks of data centers, networks of clusters in a data center, connected servers in a cluster, and multiple virtual machines on a server machine, each containing several operating systems processes....

In standard diffraction theory it is assumed that the water depth is constant and that the seabed is infinitely large. To account for a local varying bathymetry in shallow water (as it can occur for offshore LNG terminals) it is sometimes considered to introduce a second fixed body on the seabed representing this bathymetry in diffraction theory. Based on the results presented in this paper it ...

The interaction of waves and currents at an inlet entrance can be significant. Traditionally, numerical modelers have separated the processes of tidal circulation and wave transformation, but the surf zone and inlet are areas where the interactions are strong and should be numerically simulated to capture the resulting hydrodynamics. This paper describes performance of coupled wave and circulat...

Population dynamics of common intertidal bivalves (Cerastoderma edule, Macoma balthica, Mya arenaria, Mytilus edulis) are strongly related to seawater temperatures. In northwestern European estuaries, series of mild winters followed by low bivalve recruit densities lead to small adult stocks. In this study, we examine temperature-induced effects on reproductive output (eggs m22), onset of spawn...

The present study investigates the floral diversity of Lagos coastal environments by sampling 21 points using quadrat method. revealed two major aquatic ecosystem types (mangrove and freshwater swamp) recorded 125 species belonging to 108 genera 49 families. While Alchornea cordifolia Raphia hookeri were found as most frequent, Acalypha crenata Acrostichum aureum least abundant species. highest...

This paper discusses a new sort of engineering support tool that directly addresses one of the major remaining sources of delay and error in engineering projects: the need to coordinate the actions of large and often distributed engineering teams. By combining now-standard web-based enterprise information technologies with ideas and techniques from artificial intelligence we have produced a too...

Microsatellite markers were developed and employed to assess genetic maternity and paternity of embryos in nest-tended clutches of the Molly Miller (Scartella cristata), a marine fish in which alternative reproductive tactics (ARTs) by males were recently described from behavioral and morphological evidence. Genetic data gathered for 1,536 surveyed progeny, from 23 barnacle-nest holes in a sing...

Using a new DNA hybridization technique that does not require culturing, we compared the species composition of natural planktonic bacterial assemblages before and after confinement in 20 1 containers for ca 2 d Although confinement is known to cause species shifts, possibly by stimulating growth of certain types of cells near the container wall, we found that such shifts were minor; 5 to 15 % ...

Following in the footsteps of seminal studies like E. W. Soja Postmetropolis: Critical Studies of Cities and Regions (2000) or Miwon Kwon One Place After Another: Site-specific Art and Locational Identity (2004), this article constitutes a contribution to our current understanding of contemporary societies, more specifically to the shaping of urban identities and the role of contemporary art wh...
