the square map is one of the functions used in cryptography. for instance, the square map is used in rabin encryption scheme, block cipher rc6 and stream cipher rabbit, in different forms. in this paper, we study statistical properties of the output of the square map as a vectorial boolean function. we obtain the joint probability distribution of arbitrary number of the upper and the lower bits...

Directional asymmetry is a well-documented phenomenon in research on similarity, metaphor, and analogy. In . this paper, we present an account of this phenomenon based on structural alignment . We propose that a major source of asymmetry is coherence imbalance : that is, a difference in the degree of systematicity of the relational structures being compared. These claims are tested in three exp...

The inphase/quadrature (I/Q) amplitude and phase imbalance effects are studied in coherent optical orthogonal frequency division multiplexing (CO-OFDM) systems. An analytical model for the I/Q imbalance is developed and supported by simulation results. The results indicate that the I/Q imbalance degrades the BER performance considerably. Keywords—Coherent detection, I/Q imbalance, OFDM, optical...

WiMAX systems are very popular in wireless communication now-a-days. The main reason behind its popularity is high data rates possible in WiMAX systems. But due to in-phase quadrature imbalance (i.e. IQ imbalance) at the transmitter (Tx) and receiver (Rx), the system performance may be degraded in WiMAX systems. Therefore, it is necessary to compensate for the in-phase quadrature imbalance. In ...

Workload construction methodologies for multiprogram experiments are more complicated than those for single-program experiments. Fixed-workload methodologies pre-select samples from each program and use these in every experiment. They enable direct comparisons between experiments, but may also yield runs of which significant portions are spent executing only the slowest program(s). Variable-wor...

DBpedia has been proved to be a successful structured knowledge base, and large scale Semantic Web data has been built by using DBpedia as the central interlinking-hubs of the Web of Data in English. But in Chinese, due to the heavily imbalance in size (no more than one tenth) between English and Chinese in Wikipedia, there are few Chinese linked data are published and linked to DBpedia, which ...

We tested the ability of recombinant hMutSalpha (hMSH2/hMSH6) and hMutSbeta (hMSH2/hMSH3) heterodimers to complement the mismatch repair defect of HEC59, a human cancer cell line whose extracts lack all three MutS homologues. Although repair of both base/base mispairs and insertion-deletion loops was restored by hMutSalpha, only the latter substrates were addressed in extracts supplemented with...

We introduce two measures of imbalance, the team imbalance, and the field imbalance, in a tournament design. In addition to an exhaustive study of imbalances in tournament designs with up to eight teams, we present some bounds on the imbalances, as well as recursive constructions for homogeneous tournaments.

This report presents the work completed since the thesis proposal and the revised plan for the future PhD study. Two main issues have been discussed so far: diversity analysis of ensemble models in class imbalance learning, exploration of negative correlation learning on imbalanced data. Experimental design and main conclusions are simply described. More details are included in the two papers i...

We assessed sympathovagal balance in thyrotoxicosis. Fourteen patients with Graves' hyperthyroidism were studied before and after 7 days of treatment with propranolol (40 mg 3 times a day) and in the euthyroid state. Data were compared with those obtained in a group of age-, sex-, and weight-matched controls. Autonomic inputs to the heart were assessed by power spectral analysis of heart rate v...
