This presentation provides an overview of Land Information Systems (LIS). It discusses that a LIS is a digital system that contains both spatial and non-spatial land data. It then reviews the background of LIS in Western countries and how they differ from Nepal's system. The presentation outlines the key concepts of LIS including its methodology, current problems, and future planning. It aims to introduce LIS and provide context around its use and development in Nepal.
A network is a system of interconnected elements, such as edges (lines) and connecting junctions (points), that represent possible routes from one location to another.
Here I explained introduction to the network analysis in GIS.

Spatial analysis & interpolation in ARC GISKU Leuven
In ArcGIS, a data model describes the thematic layers used in the applications (for example, hamburger stands, roads, and counties); their spatial representation (for example, point, line, or polygon); their attributes; their integrity rules and relationships (for example, counties must nest within states).
An introduction to GIS Data Types. Strengths and weaknesses of raster and vector data are discussed. Also covered is the importance of topology. Concludes with a discussion of the vector-based format of OpenStreetMap data.
This presentation is about the raster and vector data in GIS which is important and costly as well, through the presentation we will learn about both type of data.

This is most benificial for the First year Engineering students.This presentation consists of videos and many applications of GIS. The processes and the other parts of GIS is also nicely explained.
GIS projects can be loaded onto mobile devices with the users' location live projected onto the project through the use of software platforms such as ArcGIS field maps.
Navigating projects (43:18)
Builders can actively map out and locate themselves during the construction phase of the project, which allows for more efficient project navigation. Builders can also make coordinate specific notes if necessary during construction.
More after construction support (44:11):
For farmers and landscape owners:
• Farmers can have their own field map of their irrigation systems.
o Easily navigate the irrigation design.
o Make coordinate specific pinpoints of any damage or breaks in the irrigation system.
o Can send harvesters and planters to specific locations.
o Can track harvest / planting progress by map.
• Landscape owners can have their own generated irrigation schedules to avoid overwatering and underwatering.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

3. INTRODUCTION
• A LIS is a digital system having spatial(Data related to the location or the position of
an object in Geographic data or data in graphical form e.g. map) and Non-spatial
data for each land holding (Data which describes the spatial data e.g. Field books,
plot registers etc ).
• A geographic information system for cadastral and land use mapping, typically used
by local governments.
• Since the two are maintained in digital form it is possible to edit, maintain, rectify
and keep the record up-to-date with least efforts.
• It is usually deals with legal boundaries of land tenure.
• Usually land record: includes resource, land use, environmental impact, and fiscal
data.
4. BACKGROUND
Western LIS Concept:
• Cadastral systems first developed in Europe to support taxation.
• Also used for managing and controlling population
• Close linkage between title registration and land ownership
• Moving towards the development of active land market and use of bank finance for
mortgage to support land market
• Multipurpose role of Cadastral system
• record all dealings that affect the ownership of land. Eg: ownership, limited rights,
land value, zoning etc.
• Parcel as the basic organizational unit
5. CONT…
cadastre system:
• The web enabled parcel based system.
• Pre modelled database ISO standard.
• Capable to handle spatial and attribute in a web browsers.
• Web based query facility.
• Login facility for data security.
• Deed submission and automated deed verification system by using XML codes.
• Online verification facility
6. CONT…
LIS in Nepal:
• First introduced in 8th periodic plan by government
• Project established under MOLRM and started work from Bhaktapur district
• Software designed to acquire non spatial data
• Separate Department, DOLIA established in 2057 by merging two components, LIS
project in MoLRM and Archieve Section in SD
• New software designed named DLIS to manage non spatial data

8. CONCEPT OF A LIS
• Modern land information systems are computer based.
• It must have the ability to geographically relate and inter-relate the data in its layers.
• For example, one layer may be represent the roads in the area.
• A second layer may illustrate the distribution of a particular plant or animal.
• The data for these layers may be stored on a single computer.
• The LIS must possess one essential attribute.
9. PROBLEMS
• Lack of clear strategy for building, operating and maintaining LIS
• Legislative framework not developed for DOLIA regarding its activities
• Existing data source-poor quality
• Lack of managerial as well as technical experience at all the levels
• Insufficient human, financial and physical resources
10. METHODOLOGY
• Maintenance of LIS
• Geodetic/Geographic control framework:
i. LIS starts with spatial reference framework.
ii. Linkage between coordinate system and legal system .
iii. Involves recovering, remonumenting, measuring, reference points used in property
description
• Conversion -- legal description to mathematical coordinates:
i. digitizing existing maps (e.g., tax parcel maps)
ii. new coverage - coordinate geometry from deed descriptions
iii. orthophoto or ground survey
11. CONT…
• Data Quality
Depends upon source material
Eg: Existing maps, deeds description
cartographic products
occupation boundaries may be different than deed boundaries- resurvey
accuracy should be commensurate with requirements of application
• Maintenance of dynamic layer
Transactional updates -accommodate constant changes and maintain historical records
System needs to move changes in data from entry point (e.g., survey/revenue/LIS office) to all
others using land record
12. CONT…
• Access and use
i. data base design is common approach to allow access throughout organization
ii. information products - many different needs must be accommodated
iii. requirement of data depends upon the users. Transparency on data is maintained
according to level of users for eg, read only access to database for public
13. CONT…
• Institutions
• Offices directly involved and having very important role in LIS in Nepal
DOS: Involved in producing Cadastral data
DOLRM: Involved in land administrations, daily transactions and updating all land related attribute data
DOLIA: in creating LIS in Nepal and archieving land records.
LMTC: Producing human resource for land management activities in Nepal
• Stakeholders
Department of Road, Department of physical planning and construction, Department of Agriculture, Department of
Irrigation, Department of Forest, Nepal Telecom, Nepal electricity Authority etc
make use of it in their program and activities
14. FUTURE PLANNING
Clear long term vision and policy
Suitable Organizational structure
Human Resource Development
Cooperation among the stakeholder
