This document discusses the use of automatic repeat request (ARQ) procedures as an option in the design of a link protocol, and the impact of the use of ARQ on IP traffic travelling over the link. ARQ is described in a general way that includes its use over a wide range of underlying physical media, including cellular wireless, wireless LANs, RF links, and other types of bearer channel. This do...
متن کاملLloyd and Cackette
The diesel engine is the most efficient prime mover commonly available today. Diesel engines move a large portion of the world’s goods, power much of the world’s equipment, and generate electricity more economically than any other device in their size range. But the diesel is one of the largest contributors to environmental pollution problems worldwide, and will remain so, with large increases ...

Society research appointment at the Radcliffe Infirmary in Oxford after working in the E.M.S. during the War. When he came to Bristol he had already a high reputation as a pathologist, specialising in morbid anatomy. His appointment to the Department of Pathology came at an important time in its postwar development, especially in relation to the teaching hospitals of the Bristol Royal Infirmary...
متن کاملA Bishop surface with a vanishing Bishop invariant
We derive a complete set of invariants for a formal Bishop surface near a point of complex tangent with a vanishing Bishop invariant under the action of formal transformations. We prove that the modular space of Bishop surfaces with a vanishing Bishop invariant and with a fixed Moser invariant s < ∞ is of infinite dimension. We also prove that the equivalence class of the germ of a generic real...
متن کاملThe Mergelyan-Bishop Theorem
We define the differential operator ∂ ∂z on infinitely differentiable functions (also called smooth or C∞ functions) on some open set in C by ∂ ∂z = 1 2 ( ∂ ∂x + i ∂ ∂y ). A quick calculation shows that ∂ ∂z obeys the product rule. Recall that a function f is holomorphic if and only if ∂ ∂z (f) = 0. A function is biholomorphic, or an analytic isomorphism, if it is holomorphic and has holomorphi...
