The group recorded raw elevation data using two methods and then adjusted the values to distribute errors under the allowable threshold of 39mm. The fieldwork was completed successfully with a total error of only 33mm.

This document contains a fieldwork report for a leveling exercise conducted by students. It includes an introduction to leveling concepts and equipment used. The objectives of leveling are outlined. Field data from 10 locations is presented showing backsight, intermediate sight and foresight readings. The data is adjusted using the rise and fall method to correct for a small misclosure error. The document provides information and calculations to determine relative elevations at survey points through leveling.
- Prepared a 2D stick model of the bridge in SAP2000 using the properties mentioned in the FHWA Bridge document
- Designed the bridge for linear and non-linear structural models to conduct analyses
- Performed different analyses on the bridge – multimode analysis, pushover analysis, time history analysis and capacity spectrum analysis
- Compared the shear force, bending moment, axial force and displacement values for each abutment and pier from all analyses and critically assessed the bridge performance
This document contains field data from a closed traverse survey conducted over three iterations. It includes horizontal angle measurements, vertical angle measurements, and distance measurements between stations A, B, C and D. The objective was to determine coordinates of each station through angular and linear field measurements. Field data tables provide the raw readings which need to be adjusted to calculate accurate coordinates and check for angular error of closure.
This document provides details on a closed traverse survey conducted by students. It includes:
1. An introduction to traverse surveys and the different types of traverses.
2. Details of the fieldwork including measured angles, distances, bearings, latitudes and departures.
3. Calculations to adjust the measured values including distributing angular error, computing horizontal and vertical distances, and determining error of closure.
4. Presentation of the adjusted course latitudes and departures, showing an improved closure with errors of 0.0281m in latitude and 0.001m in departure.

This document compares the time and speed of construction between cast-in-situ and industrialized building system (IBS) methods. It finds that IBS is typically faster, especially during the building erection phase, as prefabricated components can be assembled more quickly on site than pouring and curing concrete. However, both methods have similar timelines for design, planning and site preparation. The document also notes some potential delays for IBS, such as weather issues during erection or difficulties adapting to late design changes. Overall, IBS is concluded to be faster, but cast-in-situ may be preferable for certain building designs.

CoVID-19 sprang up in Wuhan China in November 2019 and was declared a pandemic by the in January 2020 World Health Organization (WHO). Like the Spanish flu of 1918 that claimed millions of lives, the COVID-19 has caused the demise of thousands with China, Italy, Spain, USA and India having the highest statistics on infection and mortality rates. Regardless of existing sophisticated technologies and medical science, the spread has continued to surge high. With this COVID-19 Management System, organizations can respond virtually to the COVID-19 pandemic and protect, educate and care for citizens in the community in a quick and effective manner. This comprehensive solution not only helps in containing the virus but also proactively empowers both citizens and care providers to minimize the spread of the virus through targeted strategies and education.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days

A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...DharmaBanothu
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

1.0 Introduction to Levelling
Levelling is the determination of the relative heights (altitudes) of the different points in
the area under survey, it is this information which, when coupled with that of the pan, enables a
section through the land and/or artefacts to be drawn (Clancy, 1991).
A horizontal line (or plane) of sight (line or plane of collimation) is established with a
telescope (fitted with cross-hairs) which can be turned about a vertical axis. The difference in
consecutive readings taken on a vertical staff gives the level difference between two points
which can be seen in the figure below.

Backsight (B.S.) - The first reading from a new instrument position.
Intermediate Sight (I.S.) – Readings between the backsight (B.S.) and foresight (F.S.)
Foresight (F.S.) - The last reading from an instrument position.
There leveling has two type of layouts which are the rise and fall method and the height
of collimation method.

6.0 Summary
In this fieldwork, the reduced level of Bench Mark (BM) 1 is given which is 100.00m. The
leveling process begins with obtaining the backsight (BS) of BM1 and the foresight (FS) of
turning point (TP) A. Then the auto level is shifted to obtain the BS of TP A and the FS of TP B.
This process is repeated by shifting the auto level to obtain the BS and FS of the following staff
stations and lastly go back to BM1 to obtain its FS in order to calculate the error of misclosure.
We used both the rise and fall method and the height of collimation method to calculate
the reduced level of each staff station. The error of misclosure was -0.006mm and the
acceptable range of error of misclosure was calculated using the 12+/- √k formulae where k

represents the number of set-ups, and the acceptable range of error of misclosure is +/-
37.947mm. Thus, our leveling is acceptable.
To distribute the error, the correction per set-up is calculated using the following
formulae:
Correction per set-up
= Error of misclosure ÷ Number of set up
The correction per-set up is +0.0006m and is cumulative as shown in the table provided
in the adjusted data section.
