Why One Source File Is Better Than
Engineering practice requires that details of the representation of a software module should not be accessible to clients of the module. Developers respect this practice by splitting each module into two source les, an interface and an implementation. We call this the \two-le model". We discuss an alternative model, the \one-le model", that requires the developer to write and maintain one sourc...
متن کاملThe Composite-file File System: Decoupling the One-to-One Mapping of Files and Metadata for Better Performance
Traditional file system optimizations typically use a oneto-one mapping of logical files to their physical metadata representations. This mapping results in missed opportunities for a class of optimizations in which such coupling is removed. We have designed, implemented, and evaluated a composite-file file system, which allows many-to-one mappings of files to metadata, and we have explored the...
متن کاملSingle-file diffusion of colloids in one-dimensional channels
Single-file diffusion, prevalent in many processes, refers to the restricted motion of interacting particles in narrow micropores with the mutual passage excluded. A single-filing system was developed by confining colloidal spheres in one-dimensional circular channels of micrometer scale. Optical video microscopy study shows evidence that the particle self-diffusion is non-Fickian for long peri...
متن کاملMobility of a one-dimensional confined file of water molecules as a function of file length.
Confinement of water by pore geometry to a one-dimensional file of molecules interacting with the pore alters the diffusion coefficient D(W). Here we report an exponential dependence of D(W) on the number of water positions in the pore. The result is based on measurements of single channel water permeabilities of structurally similar peptidic nanopores of different length. The inconsistency wit...
متن کاملex vivo comparison of mtwo and race rotary file systems in root canal deviation: one file only versus the conventional method
objectives : cleaning and shaping of the root canal system is an important step in endodontic therapy. new instruments incorporate new preparation techniques that can improve the efficacy of cleaning and shaping. the aim of this study was to compare the efficacy of mtwo and race rotary file systems in straightening the canal curvature using only one file or the conventional method. materials an...
