Today due to the importance and necessity of implementing security systems in homes and other buildings, systems with higher certainty, lower cost and with sensor fusion methods are more attractive, as an applicable and high performance methods for the researchers. In this paper, the application of Dempster-Shafer evidential theory and also the newer, more general one Dezert-Smarandache theory for implementing as a home security system and also using sensor data fusion have been considered. The benefits of multisensor fusion with direct connection to the control unit, in comparison with the traditional single sensor systems, have been shown.

Finding a representative fluid in a hydrocarbon reservoir is crucial for integrated reservoir management. In this study, a systematic approach for screening and selecting consistent fluid samples in a reservoir was developed. The model integrated quality control (QC) of well conditioning before sampling, QC of PVT data, thermodynamic modeling and compositional gradient within a reservoir. Well and separator conditioning were examined as essential steps before sampling at equilibrium conditions. Sampling criteria were deduced according to available data, sampling standards, and tolerance of field measurement devices. Then, PVT data of consistent fluid samples were carefully screened for efficient phase behavior studies. This model suggests that thermodynamic modeling and equation of state (EOS) tuning be performed on screened fluids using only consistent experimental data. The proposed model was implemented on PVT samples of a supergiant gas condensate reservoir in the Middle East. Results show that only 10% of collected samples are at equilibrium, good candidates for PVT studies. Also, ±0.1% change in composition of C12+ causes ±300 psia changes in dew-point pressure, revealing no substantial difference between validated samples for the reservoir under study, and one representative fluid suffices throughout the reservoir.

The aim of the current study was to investigate whether L2 dialogue shadowing practice would have an effect on Iranian intermediate EFL learners’ conversation ability. For this purpose, 30 Iranian intermediate EFL learners at Padideh language center participated in the experiment of the study. The participants were divided into two groups of 15 who were assigned to the experimental and control group of the study randomly. A pretest of conversation ability was administered to both groups, the experimental group received 10 sessions of teaching L2 conversation as well as dialogue shadowing technique (DST) while the control group received a placebo, in other words, teaching L2 conversation via existing method. After the treatment, the same test was administered as posttest to both groups of study. The data obtained from the tests in this study were analyzed via independent sample T-test between performance of the groups, and the paired-sample T-test was used between the pretest and posttest of each group to show the progress. The results revealed that Iranian EFL learners in the experimental group performed better and received higher score in conversation test after 10 sessions of treatment.
