Cramer-Rao bounds for oneand two-dimensional angle-of-arrival estimation are reviewed for generalized 3-D array geometries. Assuming an elevated sensor array is used to locate sources on a ground plane, we give a simple procedure for drawing x-y location confidence ellipses from the Cramer-Rao covariance matrix. We modify the ordinary bounds for the case of “separate” 1-D estimates and numerica...

The search-step paradigm addresses the processes involved in changing movement plans, usually saccadic eye-movements. Subjects move their eyes to a target (T1) among distractors, but when the target steps to a new location (T2), subjects are instructed to move their eyes directly from fixation to the new location. We ask whether moving to T2 requires a separate stop process that inhibits the mo...

We discuss two recently proposed adaptations of the well-known StahelDonoho estimator of multivariate location and scatter for high-dimensional data. The first adaptation adjusts the calculation of the outlyingness of the observations while the second adaptation allows to give separate weights to each of the components of an observation. Both adaptations address the possibility that in higher d...

For a mobile node that uses both Mobile IP and Session Initiation Protocol (SIP), there is severe redundant registration overhead because the mobile node has to make location registration separately to the Home Agent for Mobile IP and to the Home Registrar for SIP. Therefore, we propose two new IP mobility management methods that integrate both Mobile IP and SIP. Performance comparisons are mad...

Distribution of significant trans-eQTL in FVBBX tail epidermis. This figure plots the distribution of all eQTL measured in skin (≤ 5% FDR). Genomic location of SNPs across all chromosomes is plotted on the horizontal axis; location of probes is plotted on the vertical axis. No eQTL were calculated on the X or Y chromosomes. Solid vertical lines separate chromosomes. The dark line along the diag...

This paper offers graphic illustration of so-called “valence” models of candidates responding to their perceptions of voter location in a two-party system. Models by Groseclose and others show how the combination of candidate uncertainty about the median voter location, nonzero candidate valence, and policy motivated candidates leads to departures from the median voter prediction. With one poli...

Marr (1982) may have been one of the first vision researchers to insist that in modeling vision it is important to separate the location of visual features from their type. He argued that in early stages of visual processing there must be “place tokens” that enable subsequent stages of the visual system to treat locations independent of what specific feature type was at that location. Thus, in ...

In the paper we present a concept of making backups in the cloud. We discuss the current practice of making backup copies of data enabling backups to be stored in a separate location and analyze the possibility of making backups in the cloud. We mainly focus on the economic and performance aspects of using cloud computing for making backup copies of data.
