This document describes a project to develop an eco-friendly 3D printer that uses agricultural waste (bagasse) as a raw material instead of plastic filaments. A team led by Antony Hubert is enhancing the design of a 3D printer with components like a plunger, nozzle, bed, and motors to successively add bagasse pulp layers based on a CAD model. Testing will evaluate the stability, strength, water resistance, and thermal properties of objects printed from bagasse. Using bagasse allows plastic usage to be reduced while producing biodegradable products. This supports sugarcane farmers financially and spreads 3D printing knowledge in rural areas.

Total Quality Management (TQM) aims to make quality the first priority through a customer-focused approach involving all employees. TQM shifts the focus from quality control to quality prevention by emphasizing continuous process improvement and employee participation. The benefits of TQM for organizations include improved quality, productivity, profitability and customer satisfaction. While initial implementation costs money, TQM reduces waste and defects over time. TQM is particularly important in the pharmaceutical industry for ensuring safe, effective products and maintaining reputation through rigorous quality standards and process control.

Total Quality Management (TQM) aims to make quality the first priority through a customer-focused approach involving all employees. TQM shifts the focus from quality control to quality prevention by emphasizing continuous process improvement and employee participation. The benefits of TQM for organizations include improved quality, productivity, profitability and customer satisfaction. While initial implementation costs money, TQM reduces waste and defects over time. TQM is particularly important in the pharmaceutical industry for ensuring safe, effective products and maintaining reputation through rigorous quality standards and process control.

The document discusses Delta robots, which are parallel robots composed of three arms attached at a base with uniform joints. Delta robots are used popularly in factory picking and packaging because they can execute up to 300 picks per minute. A typical Delta robot consists of an equilateral triangular base with one arm extending from each side and connected to a small triangular traveling plate via parallelogram shaped forearms, resulting in three translational degrees of freedom and one additional rotational degree of freedom at the end effector. The document discusses applications of Delta robots in industries like packaging, medical/pharmaceutical, electronics assembly, and 3D printing. It also lists some common industrial Delta robots from manufacturers like ABB, Omron, Festo, and Fan

The document discusses solidification, phase diagrams, and the iron-carbon system. It covers the following key points:
1) Solidification involves nucleation and crystal growth as a metal cools below its melting point. Homogeneous nucleation occurs within the liquid, while heterogeneous nucleation occurs at surfaces or impurities.
2) Phase diagrams show the different phases that exist at various temperatures and compositions. The iron-carbon system features an equilibrium diagram describing the phases in steels and cast irons.
3) Gibbs' phase rule relates the number of phases, components, and degrees of freedom in a system at equilibrium. It is often applied to analyze cooling curves and determine the number of variables that can change

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.

Understanding Inductive Bias in Machine Learning
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
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.

3-6 June 2024, Niš, SerbiaEmbedded 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.
