Today, smart buildings, which combine sensors and actuators, allow owners to save energy, increase security, provide users with information about their work environment, and operate directly on the building via the Internet. Indoor environmental parameters such as temperature, humidity, lighting, and air quality are monitored by IoT sensors in smart buildings. In this paper, we propose a smart building solution for managing the indoor environment based on the Internet of Things, which aims to provide functions such as monitoring the environmental parameters of the room and detecting the number of users in the space. It is also a cloud platform where virtual entities collect data obtained by sensors and cloud virtual entities perform data analysis tasks using system learning algorithms. This cloud platform also includes a control dashboard for managing and controlling the building. The goal of this article is to define, develop, and present the results of a project that uses sensors in a standard business center to monitor and condition business units using Internet of Things technologies. The arrangement and location of the sensors are explained in this study, followed by the sensors used, wireless interfaces, and cloud technologies. The project results are presented using Bluemix and Node Red.

An understanding of of Pressure acting on underground pipes, especially for buried pipes, tunnels and shafts, is often practical and necessary during design . The physical model involves a buried pipe installed in granular soil subjected to strip surface loading. The consequence of introducing a geogrid reinforcement layer above the pipe on the distribution of contact pressure is also survived.The results of laboratory investigations to measure the pressure on pipes have been investigated using tactile sensor technology. This method allows a continuous pressure profile to be measured around the pipes using flexible sheets. Geogrids or flexible sheets are used as reinforcement to improve the strength of soil or other materials. The numerical analysis is first validated using the experimental results and then used to investigate the comprehensive behavior soil -

Assessment of vulnerability of bridges are important because when earthquake happen, the bridge must be safe for transporting people. For reaching that purpose civil engineering has made experimental and fundamental way to access result to having the best judge and modeling the bridge to have the best seismic response . For reaching damage of bridge, fragility curve is a useful tool and best way for it. Seismic response of bridge from analyzing is way for drawing fragility curve. In this research, fragility curve will present for three concrete span bridge. All part of bridge such as column and abutment have created by correct elements and materials that has shown in here. Different response will show here such as abutment response and deformation of pile and response of seismic for fragility curve. IDA test will use in this research and for reaching that need earthquake record.

In recent decades, many dams have been built. Due to the high need for water and the increasing soil erosion in different areas, the need to build a dam is quite obvious. In 1900, the number of large dams did not exceed 50. However, between 1950 and 1986, the number of large dams (more than 15 meters high) was more than 39,000. Since the 70s, the construction of dams has been developing more and more. This expansion has been more visible in the Asian, Central and South American regions. According to the construction purpose, each dam structure must be able to pass the volume of excess water caused by the flood, and for this purpose, various structures such as spillways are used. The spillways are different according to the type of exploitation and the type of project. In other words, there are different types of leaks. Which are one of these types of shaft spillway. The spillway of a morning glory consists of a circular crest that directs the flow to an inclined or vertical axis. The mentioned axis is connected to a conduct way with a low gradient. In this research, in order to investigate the performance of both vortex breakers on the hydraulic spillway of morning glory, several tests have been conducted with various types of vortex breakers. The results show that the best vorticity channel with a low height and length is an arrangement of 6, which increases the flow rate by 23%. It should be noted that increasing the thickness of the vortex breaker by more than 7% of the spillway radius does not have much effect on the increase of the spillway coefficient.
