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 ...

INTRODUCTION Identifying stroke as a cause of acute vertigo, dizziness and imbalance in the emergency room is still a clinical challenge. Many patients are admitted to stroke units, but only a minority will have strokes. This imposes a heavy financial burden on the healthcare system. The aim of this study is to develop a diagnostic index test to identify patients with a high risk of having a st...

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...

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...

Fluid imbalance can arise due to hypovolemia, normovolemia with maldistribution of fluid, and hypervolemia. Trauma is among the most frequent causes of hypovolemia, with its often profuse attendant blood loss. Another common cause is dehydration, which primarily entails loss of plasma rather than whole blood. The consequences of hypovolemia include reduction in circulating blood volume, lower v...

Coagulation has been historically investigated by the basic and time-honored tests prothrombin and activated partial thromboplastin times (PT and APTT). These tests have been instrumental for improving our understanding of the coagulation mechanisms and for the diagnosis of congenital hemorrhagic diseases such as hemophilia and allied disorders, conditions in which they are abnormally prolonged...
