Let A; B be two diagonal endomorphisms of the d-dimensional torus with corresponding eigenvalues relatively prime. We show that for any A-invariant ergodic measure , there exists a projection onto a torus T r of dimension r dim , that maps-almost every B-orbit to a uniformly distributed sequence in T r. As a corollary we obtain that the Hausdorr dimension of any bi-invariant measure, as well as...

Absfracf-The development of an autonomous land vehicle (ALV) is a central problem in artificial intelligence and robotics, and has been extensively studied. To perform visual navigation, a robot must gather information about its environment through external sensors, interpret the output of these sensors, construct a scene map and a plan sufficient for the task at hand, and then monitor and exec...

isolated scaphoid dislocation is a rare injury of the wrist. to our knowledger, only 22 cases of isolated scaphoid dislocation have been reported in enghish-language literature and we could find only one case with pure radial dislocation. we present a 34-year-old man with isolated pure radial scaphoid dislocation that was treated by open reduction and repair of the scapholunate ligament and pin...

Presenteeism refers to attending work while ill. Although it is a subject of intense interest to scholars in occupational medicine, relatively few organizational scholars are familiar with the concept. This article traces the development of interest in presenteeism, considers its various conceptualizations, and explains how presenteeism is typically measured. Organizational and occupational cor...

Our branch predictor proposed for the Championship Branch Prediction (CBP) contest is a hybrid/mutation of many different ideas previously proposed in the literature, combined with a few new techniques. The mix of traces requires the predictor to handle both capacity (large tables) and deep correlation extraction (long branch histories), both made difficult by the relatively small hardware budg...

Chlamydomonas reinhardtii flagellar motility mutant pf-14 fails to assemble radial spokes because of a deficiency for assembly-competent radial spoke protein 3 (Huang, B., G. Piperno, Z. Ramanis, and D. J. L. Luck. 1981. J. Cell Biol. 88:80-88). Here, we raise an antiserum to protein 3 and use it to isolate the corresponding structural gene from an expression library. Southern blot analysis ind...

Simulation using address reference traces is one of the primary methods for the performance evaluation of the memory hierarchy of computer systems. In this paper we survey the techniques used in such a simulation. In both the uniprocessor and shared-memory multiprocessor cases, the issues can be divided into trace collection, trace storage, and trace usage. Trace collection can employ several h...

Qu! ebec-Labrador, Canada, is one of the postulated dispersal centres of the Late Wisconsinan Laurentide Ice Sheet, and also contains an unusually complex and rich glacial geological record. A reliable reconstruction of glaciation history represented by this record would improve our comprehension of the dynamics of the eastern sector of the Laurentide Ice Sheet, such as the evolution of the bas...
