Calculating intra-aneurysm flow uses optical flow with computational fluid dynamics simulation on the numerical analysis. This is a new method to better understand the intravascular flow and aneurysm flow as well as factors related to the inflow vortex and the inflow jet which increase the rupture risk in patients with an aneurysm.

This paper presents the long-term morphological changes of the sand spits at the Ken Inlet in Ha Tinh Province and Phan Inlet in Binh Thuan Province, Vietnam. The analysis results show that the sand spit morphology at Ken Inlet was drastically changed before the completion of the Da Bac sluice gate construction in 1992, after that the sand spit elongation rate became stable at a rate of about 68 meters per year.

This study aims to evaluate the influence of electronic word-of-mouth (eWOM) on the tourist preference for the Hue tourism destination. From the surveyed data of 298 domestic tourists, we conduct Logistic Regression analysis to investigate the relationship between eWOM about the destination, the destination's image (eWOM_IM), facilities (eWOM_FA), and tourists' preference for the destination (PREF).

This paper focuses on exploring Machine learning methods to automate this process. The main challenge we face is in generating adequate training datasets to train the Machine learning model. Creating training data by manually segmenting real images is very labour-intensive, so we have instead tested methods of automatically creating synthetic training datasets which have the same attributes of the original images. The generated synthetic images are used to train a U-net Model, which is then used to segment the original bread dough images.

Identification of fracture zone is a challenging task without the image log data. There are many brownfields around the world where the image log has not been acquired; therefore, there must be an alternative way of fracture identification. In this paper, a conventional log response technique for fracture delineation has been discussed. The study area lies in the Upper Indus Basin of Pakistan, which is sub-divided into the Kohat and Potwar basins. Minwal-X-1 of Joya Mair area, which lies in the Potwar Basin, is selected for this purpose.

The tectonic and structural properties of Erzurum and its surroundings have been investigated by evaluating the seismotectonic b - value, magnetic anomaly, edge detection analysis (total horizontal derivative (THDR) and tilt angle (TA)), Curie Point Depth (CPD), P-wave velocity (Vp), and Vp / Vs (S - wave velocity) ratio and by imaging the regional distributions of these parameters. For this purpose, all parameters have been combined to be able to reveal the new useful results on the study region and are presented for different locations and depths.
