In recent years, UAM (Urban Air Mobility) has emerged as a solution to these urbanization problems, and many related reports diverse prospects have been reported. flights are planned take off land at Vertiport located in the city center fly along pre-established corridor. order for operate safely center, it must ensure safe flight path that avoids buildings surrounding obstacles. Therefore, thi...

conclusions although some of the orthopedic surgeons are not interested to manage these fractures surgically and most of them treat these cases conservatively (casting, etc.), in most displaced intra-articular calcaneal fractures, surgical treatment is the method of choice. moreover, in non-surgical treatment the prevalence of these complications among the patients is more and as a result, inev...

In this paper I analyze the interaction between sound and the visual arts as well as its development through the acoustic space and time. In other words, I am trying to understand the aesthetic implications of the sound sculpture and sound installation disciplines. Nevertheless, in order to understand the main characteristics of this relatively new media, we need first to consider some importan...

Users often install applications from untrusted sources. Alcatraz is a system that provides isolation of a system from potentially untrustworthy user programs. However, we find performance and functionality concerns with Alcatraz. Nevertheless, Alcatraz demonstrates the feasibility of one-way isolation of user programs. During a port of Alcatraz to a modern commodity operating system, Mac OS X,...

PURPOSE: To develop a method for direct measurement, using anatomic specimens, of the precision of MR-guided stereotaxic location and to describe its application to a 1.5-T MR unit with a Leksell stereotaxic frame. METHODS: Small pieces of gel foam ( 1 X 1 X 1 mm), soaked in gadopentetate dimeglumine, were stereotaxically introduced into formalin-fixed human heads using a Leksell D (three exper...

Changes in the load on electric power system suddenly cause dynamic disturbances. The disturbance causes stability of generator to be disturbed, because does not respond quickly. This oscillations form frequency and rotor angle. One additional control equipment that can increase a is Power System Stabilizer (PSS). With PSS installation, optimal response angle SMIB are obtained, indicated by min...

Cultured Atlantic salmon (Salmo salar L.) may be introduced into natural systems intentionally or accidentally. As smolts or post-smolts, they move to the feeding areas of wild salmon in the North Atlantic Ocean. As maturing fish, they return to the area of release and enter rivers to spawn. Lack of juvenile river experience is the prime reason why cultured salmon often enter fresh water later ...

Ground plane detection is essential for successful navigation of vision based mobile robots. We introduce a very simple but robust ground plane detection method based on depth information obtained using an RGB-Depth sensor. We present two different variations of the method: the simplest one is robust in setups where the sensor pitch angle is fixed and has no roll, whereas the second one can han...
