Air traffic system is analyzed from the aspects of system's attributes internal operating mechanisms and external behaviors. A hybrid air traffic simulation model described by the combination of discrete event and continuoustime models is proposed. The simulation model uses Agent-based techniques to describe micro behaviors of the air traffic individuals and integrates micro behaviors into dyna...

We utilise repeated cross sections of micro data from several countries, available from the Luxembourg Income Study, LIS, to estimate labour supply elasticities, both at the intensive and extensive margin. The benefit of the data is that it spans over four decades and includes a large number of tax reform episodes, with tax rate variation arising both from cross-sectional and country-level diff...

objective: in patients with diabetes mellitus, increased rate of lipoprotein oxidation and oxidative stress have important role in diabetic angiopathy, including nephropathy. we designed a study for comparing the level of ox-ldl in diabetic patients with macro-albuminuria, micro-albuminuria, versus normo-albuminuric. materials and methods: one hundred and thirty five patients with type 2 diabet...

A methyl green decolorization micro test for the determination of streptococcal anti-deoxyribonuclease B titers in serum is described. The micro test was compared with an alcohol precipitation macro test on 112 human sera. The anti-deoxyribonuclease B titers agreed within one dilution step for 85.7% of the 112 sera examined by both techniques. Both tests were about equal in the detection of tit...

A two-tier cellular system with a number of small micro-cells overlaid by one large macro-cell is studied. Two channel allocation strategies, Macro-cell-Centered Access Strategy and Micro-cell-Centered Access Strategy, are proposed for the low mobility calls. The system objective is to minimize handover rate with constraint of call blocking and dropping rates (total lost rate) below certain QoS...

Micro-expressions are facial expressions that have a short duration (generally less than 0.5 seconds), involuntary appearance and low intensity of movement. They are regarded as unique cues revealing the hidden emotions of an individual. Although methods for the spotting and recognition of general facial expressions have been investigated, little progress has been made in the automatic spotting...
