To get an improved image or to obtain any useful information from it, image processing is a method of implementing any operations on an image. In the method of classifying and detection of images, this process mainly contributes to the innovation of technology. The implementation of image processing in robots had been used in earlier but with different uses. Using FPV Camera 720p OIN in the projects lets it transmits live video streaming to any device attached to it. This paper shows the robustness of image processing as it detects defects on pipes. Covering the inner external part of the pipe, the robot can pass through inside the pipe. With the accuracy of 67%, the project will be tested in different pipes and drainages for the application.

Sonography is common use in early pregnancy has led to the exposure of incidental adnexal masses more often. Assessment of grayscale and color Doppler sonography outcomes is as precise when based on static images. To determine the evaluation of adnexal masses with grayscale ultrasonography and color Doppler flow imaging in first trimester of pregnancy. This Cross Sectional study was conducted at the Department of Radiology, Jinnah Hospital, Lahore, Pakistan. The study was conducted from July to Dec 2019. The patients were selected by nonprobability convenience sampling. All pregnant patients were undergoing abdominal ultrasonography to detect the adnexal masses. The data was collected by the questionnaire. Overall 68 individuals involved in this study out of which 29(96.7%) are benign diseases on the left side of patients and malignant are only 1(3.3%). Patients having benign diseases of right-sided are 33(86.8%) and malignant are 5(13.2%). Benign diseases are 62(91.2%) out of which 43 patients had cystic, 15 are mixed and 4 are solid components. Malignant diseases are found only 6 patients out of which 3 are mixed and 3 are solid components. Majority of the adnexal masses identified in pregnancy is benign and will resolve suddenly. Doppler sonography has severe limitations in the differentiation of benign from malignant adnexal disease on the basis of low-impedance flow.

Analyzing the Influence of Rain Frequency Infiltration Rate and Infiltration Capacity in Common Soil Type (Laboratory Testing Study With Rainfall Simulator). Infiltration is the flow of water into the ground through the soil surface. This process is a very important part of the hydrological cycle and in the process of transferring rain into the flow of water in the soil before reaching the river. Infiltration (infiltration rate and capacity) is influenced by various variables, including soil type, slope inclination, density and type of vegetation, soil moisture content, and rainfall intensity. This study aims to determine the effect of rainfall frequency on the infiltration rate and infiltration capacity on common soil types. This research is a type of laboratory experimental research, using rainfall simulator tool. The soil used in this study is common soil type. Furthermore, artificial rain was provided with intensity I5, I15, and I25 and performed infiltration rate reading on the Drain Rainfall Simulator. The rate and capacity of infiltration in common soils increase proportionally to the increased intensity of rainfall, the higher the intensity of rainfall the higher the infiltration occurring at the same level of rain frequency. The rate and capacity of infiltration in common soils decrease proportionally to the increasing frequency of rain, the more the frequency of rain the smaller the infiltration occurring at the same level of rainfall intensity

This paper reviews and analyses the process and built-up of the ArtScience Museum. It touches on the history, building features and Moshe Safdie’s design approach in forming the museum’s architecture. Furthermore, it explores the motivations in having a cultural institution within the Marina Bay precinct and the correlation of what it was intended to be with the identity it has formed today. The Art Science Museum can be seen as a form of an add-on to Marina Bay Sands as the tender competition project included a design for a cultural institution. However, despite it being a form of enhancement, the ArtScience Museum arose and served its purpose being an intriguing form of architecture and a place for learning for people alike.

Analysis of Effect of Land Gradation on Permeability and Ponding Time in Frequency of Repeated Rain (Laboratory Studies with Rainfall Simulator) guided by Darwis Panguriseng and Mahmuddin. That soil permeability is the ability of soil to pass water or air. Soil permeability is usually measured in terms of the speed of water flowing in a certain time specified in units of cm/hour. Ponding time (tp) is the time difference between when it rains and the time when water begins to pool above ground level. The purpose of this study was to determine the effect of soil grading on permeability and inundation time with repeated frequency of rainfall with the same intensity on mixed soil types. This research method is a type of laboratory experimental research, using a rainfall simulator. The soil used in this study is mixed soil types. Furthermore, artificial rain is given with an intensity of I15, each intensity is used five times the frequency of rain and the inundation time readings and inundation height are carried out in the Rainfall Simulator experiment tank and for the permeability test, observation is done with the constant head test. The results showed the value of the permeability coefficient is inversely proportional to the increase in rainfall intensity and frequency of rain. Inundation height and final inundation time are directly proportional to increasing rainfall intensity and rainfall frequency.
