Bricks are rectangular blocks made primarily from clay that are hardened through firing in a kiln. They have been used in construction for thousands of years due to their durability, strength, and versatility. Good brick material contains 20-30% alumina, 50-60% silica, up to 5% lime, and 5-6% iron oxide, which provide cohesion, prevent cracking, and impart color. Bricks are manufactured by preparing soil through removal of debris, blending additives, tempering with water, molding, drying, and burning in kilns to produce hardness and strength through physical and chemical changes.
FLOOR.pptx
This document discusses different types of flooring materials, including structural glass flooring which is used between floors and has a thickness of 10-30mm, marble flooring which is used where sanitation is important like in hospitals due to its hard and durable surface, PVC flooring which is laid on concrete but can be slippery so is used on walls, and asphalt flooring which comes in tiles, terrazzo and blocks and is dustless, elastic, durable, waterproof and non-slippery making it suitable for places like chemical labs.
Roofing.pptx
The roof is the uppermost part of a building that is supported by structural members and covered with roofing material to protect the building from weather elements like rain and wind. Pitched roofs are sloped while flat roofs are level, and shell roofs are curved. Pitched roofs include single, lean-to, couple, collar beam, and various types of trussed roofs to support the sloping design.
PP2.pptx
The document discusses the process of making bricks which involves moulding, drying, and burning. Bricks are moulded by hand or machine into standard sizes prescribed by the Bureau of Indian Standards. They are then dried before being burnt in kilns at high temperatures between 700-1000°C, which causes physical and chemical changes that make the bricks strong and resistant to cracking. Good quality bricks are uniformly shaped, well-burnt, and produce a clear ringing sound when struck. They also absorb less than 20% water and have sufficient hardness and crushing strength. Bricks are classified based on their burning process as sun-dried, burnt, and overburnt.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Low power architecture of logic gates using adiabatic techniques
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
