    Notes: Abstract Although the signal-to-interference power ratio (SIR) based criterion for diversity reception has been highlighted in the literature as the most effective method for reducing the effects of cochannel interference, it is often not clear how to measure this parameter in a practical context. This work addresses the problem of finding a way to determine the level of interference (due to frequency reuse) from neighbouring cells in a mobile telephone system, with M-ary PSK modulated signals and fast fading channel. The proposed parameter measures the quality of the received signal corrupted by additive white noise and cochannel interference, for any number of interferers. It is also suitable for high bit rate transmission, as in indoor mobile radio systems, since the proposed method requires sampling the received signal at just one sample/symbol.

    Notes: Abstract The purpose of this paper is to develop optimal tool partitioning policies and strip sequencing strategies for a class of flexible manufacturing problems. The problems under consideration involve a large number of operations to be performed by a series of tools on a two-dimensional object. For example, these operations could consist of drilling holes in a metallic sheet. Tools are arranged in a carousel or along a toolbar according to a predetermined sequence. Operations are performed by repeatedly moving the sheet to bring the hole locations under the tool. During each pass, as all operations involving a series of consecutive tools are executed, two main problems are to be solved: (1) how to move the sheet during each pass, (2) how to partition the tools into blocks of consecutive tools. A strip strategy is used to move the sheet. Given this policy, optimal strip widths and tool partitioning policies are determined jointly. Analytical solutions are derived under two metrics corresponding to different operating modes. A numerical example is provided.
