In this paper we design some characteristics of a possible E-governance system for the urban mobility. In particular we shortly present the complex city features and the background automata gas paradigm for a microscopic modeling. Moreover we show some statistical laws based on long time series of traffic dynamics data, fundamental for the now-casting and the private vehicles mobility control. ...

The ability of foam to control the gas mobility in porous media is determined in part by the trapped (stationary) fraction of foam, Xt. The common approach to determining Xt is to replace some part of the gas by a “tracer gas” during the steady-state stage of the experiments and fitting the effluent data to a capacitance mass-transfer model. Diffusion between bubbles is quantified by the film p...

In this study, an organic-inorganic semiconductor gas sensor was fabricated to detect ammonia gas. An inorganic semiconductor was a zinc oxide (ZnO) nanowire array produced by atomic layer deposition (ALD) while an organic material was a p-type semiconductor, poly(3-hexylthiophene) (P3HT). P3HT was suitable for the gas sensing application due to its high hole mobility, good stability, and good ...

Objectives: The main purpose of this research was to study the effectiveness of positive thinking skills training on increasing happiness of male adolescents with physical-mobility disability. Methods: In this study an experimental research design with pre-test, post-test, and control group is used. All adolescents (boys) having disabled physical mobility from all the high schools in southern ...

The use of CO(2) as a massive and polarizable drift gas is shown to greatly improve peak-to-peak resolution (R(p-p) ), as compared with N(2) , for the separation of disaccharides in a Synapt G2 traveling wave ion mobility cell. Near or baseline R(p-p) was achieved for three pairs of sodiated molecules of disaccharide isomers, that is, cellobiose and sucrose (R(p-p)  = 0.76), maltose and sucrose...

Laser desorption ionization (LDI) and ion mobility mass spectrometry (IM-MS) are applied to study molecular weight distribution and cross sections of petroleum asphaltene (ASPH) and deasphaltened oils (DAO). Ion mobility data confirmed the presence of gas-phase aggregation in LDI experiments. Most of the molecules with MW > 3000 g/mol in LDI result from gas-phase aggregation. Two-dimensional (2...

In this work, studies of underground gas storage (UGS) were performed on a partially depleted, naturally fractured gas reservoir through compositional simulation. Reservoir dynamic model was calibrated by history matching of about 20 years of researvoir production. Effects of fracture parameters, i.e. fracture shape factor, fracture permeability and porosity were studied. Results show...

Differential mobility spectrometry (DMS) of nitro-organic explosives and related compounds exhibited the expected product ions of M- or M x NO2- from atmospheric pressure chemical ionization reactions in purified air at 100 degrees C. Peaks in the differential mobility spectra for these ions were confined to a narrow range of compensation voltages between -1 to +3 V which arose through a low de...

Cooperative vehicle infrastructure system (CVIS) or connected vehicles, formerly known as IntelliDrive, has emerged and is expected to provide unprecedented improvements in mobility and safety. A recent study developed a CVIS-based urban traffic control system that does not require a stop-and-go style traffic signal. A simulation-based study on the CVIS-based control found significant improveme...
