Dynamometers
Dynamometers are devices used to measure torque and power. There are two types: absorption dynamometers and transmission dynamometers. Absorption dynamometers absorb the engine's power through frictional resistance, which is transformed into heat. Transmission dynamometers transmit the engine's energy for work. Common absorption dynamometers include the Prony brake and rope brake, which measure torque by balancing frictional resistance with a weight. Transmission dynamometers include the epicyclic train dynamometer, belt dynamometer, and torsion dynamometer, which transmit power through gear trains, belts, or shaft twisting.
Weekly report 2
This weekly report summarizes the progress of the Conthai engineering team. They tested a voltage divider circuit using three resistors to regulate voltages from 0.5V to 4.5V for a microcontroller. They calculated and measured the output voltages, finding small errors between the calculated and measured values due to resistor tolerances. Their next steps are to present their rice cooking project and finish the design.
Mechanics of Machines - Experiment 3
This document provides instructions for a lab experiment on static and dynamic balancing. The objectives are to demonstrate static balancing techniques and draw force polygon diagrams. Students will use a balancing apparatus, weights, protractor, and Allen keys. They will adjust weight positions, observe the system's rotation, and draw force polygons to balance the system both statically and dynamically. Questions address why balancing is important and how static and dynamic balancing differ.

Supply chain visibility
The global supply chain has become so complex that communication and collaboration of parties outside and inside the enterprises have become critical. This can be achieved through transparency in the supply chain. Supply chain visibility promises numerous benefits, including reduced costs and customer satisfaction. However, these are only two of the main reasons why it is critical to your enterprise.
Death of Enterprise: Consequence of Poor quality data
Quality data should be the top 5 priority of enterprises if they want to succeed. Many organizations struggle with poor quality data, which ultimately leads to poor decision-making. Essentially, decisions are based on the data available. This means that wrong decisions can be made with poor quality data. On the other hand, reliable, accurate and complete data supports efficiency and is the cornerstone for sound decision-making.
Airline Staff Levels
This document analyzes staffing levels at three airlines: Alaska Airlines as a low-cost carrier, and Singapore Airlines and Delta Airlines as full-service carriers. It finds that full-service carriers have higher staffing levels per passenger and aircraft compared to low-cost carriers. Specifically, Singapore Airlines has 9.63 staff per 10,000 passengers and 134.8 staff per aircraft, while Alaska Airlines has 3.6 and 74.7 respectively. The higher staffing levels at full-service carriers increases service quality by allowing more employee attention per passenger.

This document provides information about parallel circuits. It defines parallel circuits as those where components are connected such that current can divide and flow through multiple components simultaneously. Some key points made include:
- In parallel circuits, the current through individual branches can vary but the total current increases as total resistance decreases.
- The total resistance of a parallel circuit decreases as more resistors are added in parallel, as these provide additional paths for current to flow.
- The voltage across each component/resistor in a parallel branch is the same.
- Examples of parallel circuits include household electrical wiring and multi-core computer processors.

Integration of-virtual-learning-of-induction-machines-for-undergraduates
In context of understanding problems faced by undergraduate studentswhile carrying out laboratory experiments dealing with high voltages, it was found that most of the students are hesitant to work directly on machine. The reason is that error in the circuitry might lead to deterioration of machine and laboratory instruments.So, it has become inevitable to include modern pedagogic techniques for undergraduate students, which would help them to first carry out experiment in virtual system and then to work on live circuit. Further advantages include that students can try out their intuitive ideas and perform in virtual environment, hence leading to new research and innovations.In this paper, virtual environment used is of MATLAB/Simulink for three-phase induction machines. The performance analysis of three-phase induction machine is carried out using virtual environment which includes Direct Current (DC) Test, No-Load Test, and Block Rotor Test along with speed torque characteristics for different rotor resistances and input voltage, respectively. Further, this paper carries out computer aided teaching of basic Voltage Source Inverter (VSI) drive circuitry. Hence, this paper gave undergraduates a clearer view of experiments performed on virtual machine (No-Load test, Block Rotor test and DC test, respectively). After successful implementation of basic tests, VSI circuitry is implemented, and related harmonic distortion (THD) and Fast Fourier Transform (FFT) of current and voltage waveform are studied.

The document provides information about calibrating different types of thermocouples using a thermocouple calibration apparatus. It discusses that a thermocouple measures the temperature difference between its two junctions by producing a voltage proportional to the temperature differential. The experiment involves calibrating thermocouples like K-type and T-type using the calibration apparatus and comparing the readings to known standards to determine accuracy. The summary provides an overview of the key aspects and goal of the thermocouple calibration process discussed in the document.

This document describes the design of a combined fatigue testing machine that can test specimens using both rotating shaft and reciprocating bending mechanisms. It discusses the working principles and design considerations for the machine components like the electric motor, bearings, crank and connecting rod assembly, sensors, and specimens. The machine is designed to be compact, efficient, and more economical than commercially available fatigue testing machines. It will subject specimens to repeated stresses and count the number of cycles until failure to generate S-N curves, which graphically represent the relationship between stress amplitude and number of cycles to failure.

How to Fix the Import Error in the Odoo 17
An import error occurs when a program fails to import a module or library, disrupting its execution. In languages like Python, this issue arises when the specified module cannot be found or accessed, hindering the program's functionality. Resolving import errors is crucial for maintaining smooth software operation and uninterrupted development processes.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
