THE IMPORTANCE OF SOIL WELDING IN CIVIL CONSTRUCTION

2024-11-05T16:52:11-03:00

The study addresses the importance of soil welding in civil construction. Welding is important, as we obtain information from the soil to carry out the sizing of the foundation. Through this study we obtain the main information on the type of soil, groundwater level, soil layers and the resistance of these layers. With this information, we can determine the type of foundation suitable for that specific project. Welding is one of the first phases of the work. The function of welding is to study the layers of the land where the building will be built, through which we obtain details that can even compromise the visibility of the construction. There are several types of surveys and the choice will be determined by the technical professional, varying according to the terrain and construction. Welding can be done using specialized equipment, where excavations are made to know the characteristics of the terrain. Depending on what is found in the ground, the entire progress of the work can be modified, including the foundation design, which must follow the physical aspects of the land.

PHYSICAL ARRANGEMENT OF AUTOMOTIVE PARTS IN-HOUSE

2024-11-05T16:52:11-03:00

Through structured planning, it is possible to transform, implement and improve the functioning of a production chain. One of the essential tools for the proper functioning of a production chain is the definition of the operating layout or better known as physical arrangement. Physical layout concerns the physical positioning of a company's transformative resources. This goes from facilities, equipment, employees and the way in which these items relate. The physical arrangement is one of the most evident characteristics of a productive operation because it determines its shape and appearance. The wrong physical arrangement can lead to long and confusing flow patterns, stockpiles of materials, customer queues, long processing times and high costs. These are some examples of errors in implementing the wrong physical arrangement. Physical arrangement changes are often a difficult and long-lasting activity because of the specific physical dimensions of the promoted transformation resources.

INTERFERENCE OF GROUNDWATER IN EXCAVATED PILES

2024-11-05T16:52:11-03:00

The study tends to investigate groundwater interference in excavated piles, where at certain times during soil drilling we may face problems, whether due to variation in the survey, variation in the water table (where there will be lifting of the same) or also due to the lack of a survey and, with that, the appearance of water will happen. With the existence of water in the foundation, it is difficult to assemble the piles made in situ, without their protective layer, since for manual excavation, the soil layer must have a certain resistance, otherwise collapse may occur. and high construction costs.

O THE QUALITY ASSESSMENT PROJECT PLAN IN SOFTWARE DEVELOPMENT

2024-11-05T16:52:11-03:00

To ensure success in the development or acquisition of software, it is essential to specify its quality from the beginning of the project and ensure that the final product meets the real needs of users. Software quality management is essential to ensure that it meets the requirements and expectations of end users, applying methods and techniques aimed at quality in all phases of the project life cycle. One of the main elements of software quality management is the Quality Assessment Project Plan. This plan describes the activities and resources necessary to evaluate the quality of the software during its development, defining the quality objectives to be achieved, the metrics to measure quality, the evaluation activities used and the team responsible for execution. It should be developed at the beginning of the project and updated regularly as the project progresses. You must also consider the quality requirements specific to the software in question, as well as relevant standards and regulations. The first step in the plan is to define quality objectives. This involves identifying which features of the software are considered critical to the success of the project and setting specific goals for each of these features. Next, the plan must identify metrics to measure software quality. These can be static metrics, such as code complexity or compliance with coding standards, or dynamic metrics, such as failure rate or response time. Metrics must be chosen according to specific quality requirements and must be measurable, objective and relevant. After defining the quality objectives and metrics, the plan must describe the evaluation activities that will be carried out. This may include code reviews, unit tests, integration tests, system tests, and acceptance tests. The plan must specify which activities will be carried out, when they will be carried out and who will be responsible for their execution. Finally, the plan should include a description of the team responsible for assessment activities. It may include developers, IT specialists, and other project team members. The plan must also define required resources, such as testing tools and environments, and must consider time and budget constraints.

ACRM: ANALYSIS AND CONTROL OF REPAIRS AND MAINTENANCE

2024-11-05T16:52:14-03:00

A plastic mold is an essential tool in the injection plastic parts manufacturing industry. It emerged at the end of the 19th century, but its modernization occurred with the development of the plastics industry in the 1940s. It is a structure, generally made of steel or aluminum, which contains cavities that determine the shape and characteristics of the final part. . During the injection manufacturing process, plastic is melted and injected into the mold, where it is cooled and solidified to take on the desired shape. Plastic molds are precisely designed to ensure consistency in the mass production of plastic parts, with special attention to geometry, dimensional tolerances and surface finish. They play a key role in the production of a variety of products, from small components to parts of larger products, and are essential in ensuring quality, efficiency and economy in plastic manufacturing processes, being used in diverse sectors, from automotive to packaging. . Examples include bottle caps, electronic components, and parts of household appliances. Since it is a very useful tool for creating plastic utensils commonly seen in everyday life, it is normal for companies specializing in this area to emerge, and along with that, some problems. Loss or misplacement of molds is a significant problem that can result in high costs and production interruptions. In many companies, the mold tracking and management process is performed manually, which can be prone to errors and inconsistencies. This can lead to difficulties locating specific molds, lack of inventory transparency, and even permanent loss of valuable assets.An effective solution to address this problem is the implementation of an automated mold tracking system, using a web application developed in Python. This application would allow digital recording of all the company's molds, including details such as serial number, type of mold, usage history and current location. By migrating to a computerized system, the company could reap a series of significant benefits. Firstly, operational efficiency would be increased as the time spent manually searching for molds would be drastically reduced.

MODELING AND SIMULATION OF AN ARTICULATED ROBOTIC MANIPULATOR

2024-11-05T16:52:14-03:00

The 4 degrees of freedom industrial robot stands out for its versatility and flexibility. It is designed to perform a wide range of tasks in industry, such as moving materials, parts and tools accurately and efficiently. The main objective is to analyze both the kinematic and dynamic models of this robotic manipulator and simulate its performance in different conditions with the Scilab software. To model a robotic arm, we follow a systematic approach. First we define the components of the arm, including the links (rigid segments) and the joints (connection points between the links), identifying the number and type of joints present. Next, a coordinate system is established for each link and joint, allowing its position and orientation to be described in relation to a global reference system. This is fundamental for the kinematic and dynamic analysis of the robotic arm. The Denavit-Hartenberg (DH) convention is applied to describe the geometry and kinematics of the arm, assigning DH parameters to each joint to define transformations between adjacent coordinate systems. Based on the DH parameters and homogeneous transformations, direct kinematic equations are derived, enabling the calculation of the final position and orientation of the effector in relation to the global system, given the joint configurations. If necessary, inverse kinematic equations are developed to determine the joint configurations required to position the end-effector in a specific position and orientation in the workspace. Furthermore, it is crucial to perform inertia modeling of the robotic arm, determining the masses, moments of inertia and inertia products of each link. This is essential for calculating the forces and torques in arm movements and designing suitable controllers. Finally, based on inertia models and kinematic equations, direct and inverse dynamic equations are developed, allowing the calculation of the forces and torques necessary in the joints to produce a specific movement of the arm, or vice versa. Scilab is used for simulation, offering a platform to test control algorithms. Manipulation and simulation are crucial in the development of robotic systems, driving efficiency and adaptability. Continuing technological advances in this area promise new applications in the future.

RETROFIT OF ELECTRICAL INSTALLATIONS AT FAZENDA ESCOLA UBM

2024-11-05T16:52:15-03:00

In the 70s in Brazil, there was an increase in urbanization, as a result of which civil construction was boosted. Accompanying this growth, work accidents arose, which aroused the need for regulation in the services provided, including electrical installations. Then the Regulatory Standards, the so-called NRs, emerged, as they were published in the Official Gazette of the Union in July 1978. Many old installations were not regulated, despite being often established with technical operating criteria. Safety precautions in electrical installations such as sizing of conductors, ducts and division of electrical circuits were most of the time not taken into consideration. This scenario not only put the integrity of the facilities at risk, but also that of people. Dependence on electricity is increasingly present today, becoming fundamental for the development and well-being of society, marking its presence even in places previously considered remote, such as rural facilities. Technological advances drive a growing demand for electrical energy, which leads to greater responsibility and awareness when it comes to electrical installations. Given this, there is a need to adapt and modernize the electrical installations at the UBM School Farm. Founded decades ago, this institution is located in a rural area, and plays a fundamental role as an educational establishment. Faced with this challenge, a project is being developed with diagrams, demand calculation and forecasting, load forecasting, among other specifications. The project strictly follows the guidelines established by Regulatory Standards, as well as important documents such as RECON from the electric energy concessionaire LIGHT and books by experts in the field. This project is committed to safety, energy efficiency and the sustainability of the electrical installation at the UBM School Farm.

BATTERY COLLECTION STATION

2024-11-05T16:52:15-03:00

E-waste can result in several complications, such as soil and water contamination and illnesses that can affect anyone who comes into contact with a disposal site. The danger in disposing of batteries lies in the fact that, if disposed of incorrectly, they can be crushed or burst, leaking the toxic liquid inside. This substance accumulates in nature and, as it is not biodegradable, can contaminate water. In this context, I propose a battery collection station, which would be installed in public places such as schools and businesses, with the aim of allowing the local population to deposit their used batteries. In this project, the station was installed at the Sesi – Barra Mansa school, in order to solve this problem of inadequate disposal of highly toxic waste. Once collected, these materials will be taken to the company CSN (specifically at deposit 50, which is a waste distribution point) and will subsequently be sent to a special waste landfill where they will be discarded correctly without the risk of contamination of the material. soil or groundwater resulting from the irregular disposal of these products.

COIL CONVEYOR CURRENT MIST LUBRICATION SYSTEM

2024-11-05T16:52:16-03:00

The mist lubrication system is a technique used in industry to provide lubrication to mechanical components by dispersing small oil droplets in the air. This method involves atomizing the oil into fine particles, creating a mist or spray, directed to specific areas that require lubrication in industrial equipment, engines and gears. This technique offers significant advantages, such as reducing lubricant waste, as the system allows for a more precise and targeted application. Furthermore, the oil mist can reach difficult-to-reach areas, ensuring uniform coverage on the surfaces to be lubricated. Another benefit is the additional cooling potential provided by oil mist, helping to control the temperature of mechanical components in operation. Spraying the oil in small droplets minimizes contamination of the working environment and reduces unwanted leaks, which can occur with conventional lubrication methods. However, the effectiveness of this system depends on the appropriate selection of mist droplet size, air pressure, frequency and location of application to ensure efficient lubrication without excess. In summary, the mist lubrication system is an advanced technique that provides precise oil distribution to mechanical components, resulting in effective lubrication and reduced lubricant waste. It requires careful adjustment of parameters to ensure the best results.

LIGHTWEIGHT CONCRETE: USE OF EXPANDED POLYSTYRENE IN CONCRETE

2024-11-05T16:52:16-03:00

The study approaches the use of expanded polystyrene added to concrete, where coarse aggregates are replaced by EPS at percentages of 25% and 50%, thus making a comparison with the reference concrete mix, which does not have EPS. in its composition. In demonstrating the results, it is observed that expanded polystyrene guarantees greater lightness to the concrete, but, on the other hand, its presence in the concrete mix is linked to lower resistance values. Therefore, EPS is recommended for structures that do not require greater effort, in addition to having lower density. When analyzing curing time, the idea explored is that increasing the curing period directly influences the resistant property of concrete.

A ARTIFICIAL INTELLIGENCE IN ADMINISTRATION

2024-11-05T16:52:17-03:00

Artificial Intelligence (AI) is a reality that is profoundly transforming the way organizations around the world manage their processes, make decisions and interact with their partners and customers and its history goes back several decades. As early as the 17th century, philosopher René Descartes suggested that animals could be seen as machines, establishing a connection between mind and body. This notion influenced later thinking about creating intelligent machines. In the 19th century, the ideas of mathematician Charles Babbage, who designed the Analytical Engine, considered a precursor to modern computers, were fundamental to the development of computing. At the beginning of the 20th century, mathematician Alan Turing proposed the concept of a “universal machine” capable of performing any calculation described by an algorithm. He also formulated the famous “Turing Test”, which assesses the ability of a machine to exhibit intelligent behavior indistinguishable from that of a human being. In the 1950s, scientist John McCarthy coined the term “Artificial Intelligence” and organized the first conference on the subject. It was at this time that advances emerged in areas such as machine learning and chatbots, such as Eliza, which was the first conversational program. Since then, AI has evolved rapidly, encompassing areas such as artificial neural networks, natural language processing and machine learning systems. In administration, this technological revolution brings with it a series of significant implications, ranging from the optimization of operational tasks to the redefinition of business models. AI is shaping the future of management, and its impact will be felt across all areas. Its possibilities are vast and impact different aspects of management. It can optimize processes, improve decision-making, personalize customer experiences and even predict future trends. Through machine learning algorithms, data analysis and intelligent automation, management benefits from greater efficiency, productivity and competitiveness. However, it is essential to consider ethical challenges such as privacy and algorithmic bias to ensure AI is applied responsibly and strategically. This work seeks to explore the impacts and changes that AI brings to administration, considering both the benefits and challenges.
