The decorrelating and the linear, minimum mean-squared error (MMSE) detector for asynchronous code-division multiple-access communications ideally are infinite memory-length detectors. Finite memory approximations of these detectors require the inversion of a correlation matrix whose dimension is given by the product of the number of active users and the length of the processing window. With in...

In this paper, we propose, based on the analytical analysis of the received signal for single carrier overlap frequency domain equalizer (SC-OFDE) equalization, an optimum design of the overlap frequency domain equalization. From the estimation of the received signal-to-interference-and-noise-ratio (SINR), we propose an algorithm that automatically adapts one important parameter of the OFDE equ...

In this work, we investigate sensor design approaches for eliminating the effects of parasitic resistance in nanowire and nanoribbon biosensors. Measurements of pH with polysilicon nanoribbon biosensors are used to demonstrate a reduction in sensitivity as the sensor length is reduced. The sensitivity (normalised conductance change) is reduced from 11% to 5.5% for a pH change from 9 to 3 as the...

We consider time-space tradeoffs for exactly computing frequency moments and order statistics over sliding windows [16]. Given an input of length 2n− 1, the task is to output the function of each window of length n, giving n outputs in total. Computations over sliding windows are related to direct sum problems except that inputs to instances almost completely overlap. • We show an average case ...

We extend prior research on system call anomaly detection modeling methods for intrusion detection by incorporating dynamic window sizes. The window size is the length of the subsequence of a system call trace which is used as the basic unit for modeling program or process behavior. In this work we incorporate dynamic window sizes and show marked improvements in anomaly detection. We present tw...

Human cognitive capabilities are under constant pressure in the modern information society. Cognitive load detection would be beneficial several applications of human–computer interaction, including attention management and user interface adaptation. However, current research into accurate real-time biosignal-based lacks understanding optimal minimal window length data segmentation which allow ...

We consider a pair of adjacent quantum waveguides, in general of different widths, coupled laterally by a pair of windows in the common boundary, not necessarily of the same length, at a fixed distance. The Hamiltonian is the respective Dirichlet Laplacian. We analyze the asymptotic behavior of the discrete spectrum as the window distance tends to infinity for the generic case, i.e. for eigenva...

We present a first order analog-to-digital converter with time-variant window. If a DC input is applied, the converter outputs a binary sequence until the internal state enters into the window. It is clarified analytically that the converter can realize higher resolution and lower error variation with shorter code length than previous converters. We also present a simple implementation method u...
