The document discusses the Pahl and Beitz model of conceptual design. It explains that Pahl and Beitz introduced a systematic method for conceptual design of new products in 1977. The method has since been improved and expanded with new techniques and tools, forming an integrated, customer-driven conceptual design method (ICDM). The document provides a brief explanation of three tools used in ICDM: an enriched quality function deployment for task definition, conceptual failure mode analysis, and design quality measurement for evaluating generated concepts. It notes that other new tools in ICDM include design-to-cost analysis, robustness evaluation and improvement, risk and time-to-market analysis, and direct synthesis optimization. ICDM has been used successfully

It outlines how the first Factories Act was passed in 1881 in India to protect child workers and provide health and safety measures. Subsequent acts expanded coverage to more factories and included provisions around health, safety, welfare, working hours and annual leave for workers. The current Factories Act of 1948 defines a factory and outlines its objectives to ensure worker safety, health and welfare. It also details some provisions around factory cleanliness, ventilation, drinking water and working hours for adults.
GE-Physical and Chemical properties of Milk-KAVI.pptx
Milk is a white or yellow-white opaque liquid secreted by mammals for nourishing young. It has several physical and chemical properties. Physically, milk is turbid and opaque due to light scattering by fat globules and protein micelles. It has a sweet flavor naturally but can develop off-flavors from bacterial growth, enzymes, and other chemical reactions. Chemically, milk contains water, fat, protein, lactose, minerals, vitamins, and enzymes. The fat is suspended in milk as fat globules surrounded by a phospholipid membrane that allows the fat to rise to the top and form cream.
CIM-Solid Modeling -KAVI.pptx___________
Solid modeling uses complete, unambiguous geometric representations of physical objects. It addresses weaknesses of wireframe and surface modeling like ambiguous or incomplete geometry descriptions. There are four main solid modeling representation schemes: (1) constructive solid geometry (CSG) uses boolean operations on primitives to build models through procedural descriptions, with compact data storage; (2) boundary representation explicitly defines models by their edges and faces. CSG allows easy construction but has limited modeling capability while boundary representation contains more detailed shape information.
IEM -Types of Maintenance -KAVI.pptx______
Maintenance serves several important purposes: to protect physical assets, manage risks, preserve aesthetics, and ensure full service life. There are different types of maintenance: breakdown maintenance repairs equipment after failure; preventive maintenance aims to prevent failure through inspection and repairs; and corrective maintenance improves equipment reliability to allow for effective preventive maintenance. Preventive maintenance includes periodic and predictive maintenance, with predictive using condition monitoring to predict part lifecycles. Condition monitoring programs help reduce catastrophic failures by identifying problems before failure occurs.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Advanced control scheme of doubly fed induction generator for wind turbine us...
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.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
Recycled Concrete Aggregate in Construction Part II
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
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.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

- 3. EXPLANATION OF PAHL AND BEITZ • The systematic method for conceptual design of a new product has been introduced as a comprehensive design tool by Pahl and Beitz in 1977 and improved since. In our studies the method has been extended by introduction of new techniques and tools, that enable to be more specific and more focused. The design methodology is called ICDM – Integrated, Customer Driven, Conceptual Design Method. Three out of the new ICDM tools are shortly described in this paper. These tools are the Enriched QFD for task definition, the CFMA – Conceptual Failure Mode Analysis and the DQM – Design Quality Measurement to evaluate the satisfaction from the generated concepts. The other new tools like the CDTC – the Conceptual Design To Cost, the Roobustool – to evaluate and improve the robustness of the solution combination, the RTA – the Risk and Time to Market Analysis and the DSO - the Direct Synthesis Optimization, are only shortly mentioned. ICDM has been used extensively in many Israeli start-up companies and also in classical industrial companies that adapted the method to their special needs .
