Concrete is still widely used for structural purposes as a building material. Testing the compressive strength of concrete is the most essential aspect of determining the quality of the concrete. This research was conducted to ascertain the correlation value of the compressive strength test results of concrete conducted in the laboratory with a compression strength machine (destructive test), a hammer test, and an ultrasonic pulse velocity (non-destructive test). Cylindrical specimens with 15 MPa, 20 MPa, and 25 MPa concrete strength were subjected to testing. Based on the results of the upv test and compression test, the regression equation for the relationship between wave velocity and concrete compressive strength is determined.......

Paving blocks, which consist of concrete bricks blended with sand and cement, are frequently employed in ground surface hardening construction due to their favorable characteristics. These include being precast materials that possess a comparatively sizable form, the capability to absorb water, comparatively affordable prices, and ease of manipulation. Paving blocks consist of supplementary components, specifically mineral admixtures, in addition to the primary components of water, aggregate, and cement. The inclusion of these substances serves to enhance the overall quality of paving blocks. Included among the mineral admixtures utilized in this investigation are gypsum, quartz grit, and limestone.......

Thyroid nodules, which are characterized by unusual thyroid cell proliferation, may be a sign of an iodine intake that is too high, thyroid degeneration, inflammation, and other disorders. Although thyroid nodules are mostly benign, the chance that they are cancerous increases considerably each year. Many experiments have been conducted to identify thyroid nodules using deep-learning-based image recognition analysis, reducing the labour of medical professionals and avoiding unnecessary fine needle aspiration and surgical removal. The data was imported directly from the hospitals in Algeria, and volunteer doctors labelled it........

This research focuses on a particular transmission network relevant to an urban area that is transforming swiftly. The selected network offers electricity to households, industries, and critical infrastructure, acting as an essential resource for the site. This case study was justified courtesy of its direct application to practical situations. Considering the nuances of this network is essential given the evolving energy needs and the requirement for a stable, sustainable power source. Through an in-depth analysis of this particular transmission system, critical information can be determined to solve emerging concerns that urban areas around the world are facing. This paper advances academic knowledge while also having practical implications that will direct future expansion plans and ensure the continuous supply of energy in critical urban areas.

Transmission network expansion is critical to fulfilling the rising energy demands of urban areas. As cities grow, so does the needfor a vital, dependable, long-term electricity source. However, the problem is optimizing the current infrastructure and strategically expanding it to ensure uninterrupted energy distribution. This study dives into the intricacies of transmission network expansion planning, addressing the critical need for cost-effective measures in the face of increased energy consumption. This project intends to create solutions that balance the demand-supply relationship by investigating novel approaches and incorporating cutting-edge technologies. The primary goal is to develop informed growth plans that encourage network capacity, environmental sustainability, economic feasibility, and long-term energy resilience.

In this paper, we investigated the magnetohydrodynamics (MHD) boundary layer flow with heat and mass transfer over a moving vertical plate in the presence of magnetic field, thermal radiation, heat absortion/injection, chemical reaction and a convective heat exchange at the surface with the surrounding. Partial differential equation describing the problem is formulated and the similarity variable is used to transform the system of partial differential equations, describing the problem under consideration, into a boundary value problem of coupled ordinary differential equations, and an efficient numerical technique with help of Maple is implemented to solve the reduced system. The results are presented graphically.......

From the perspective of visual perception, 87% of human consciousness is obtained by visual senses, and color is an important way to provide spatial recognition consciousness. Cold cities have different geographic locations and climate conditions from other cities, and under the multiple influences of nature and humanities. The color of cold cities have distinctive features, with mainly gray color in overall architecture. Low saturation color dominated by natural color fill the winter season. The choice of color is crucial in the process of updating public street green spaces. In addition to considering the color itself, the surrounding regional environment should also be taken into account. Northeast China, nowadays, the artificial application of high saturation color has been widely recognized. High saturation color has the characteristics of strong attraction and visual impact, which can increase the attractiveness of the green space and enhance the experience of the masses. The article summarizes the research on the application of high saturation color in the public street green space of the cold land, understands the method of application of the color, clarifies the importance of the color, and provides a reference thinking for the application of the color design of the urban landscape construction in the cold land of China. It also provides a reference for the application of color design in urban landscape construction in cold areas of China. .

Robotics has been around for many years. The first modern robot was invented in 1950s. It was an inventor from Louisville, Kentucky by the name of George C. Devol. As technology advances, we have many robots available today. In today's world most places need robots to ease the workflow. However, most of the existing robots we need to constantly try and improve them in many ways. This paper proposes a Multi-Threaded Real-Time Operating System (RTOS) based Robotic Car controlled through an Android App. This robotic car facilitates users to wirelessly control the robotic car via their Android mobile phone. Three different modules are operating concurrently in the device – microcontroller, RTOS, and Android app. The first module is the microcontroller which processes various input/output data. The second module is RTOS which takes the user's input and prioritizes which task it will execute. Lastly, the Android app which is a user interface where the user can input the direction they want the robotic car to move.

Key Words: Multi-Threaded Real Time Operating System, Robot, Android App.
