Following are some suggestions for future research. As GFRSCC technology is now being adopted in many ountries throughout the world, in the absence of suitable standardized test methods it is necessary to examine the existing test methods and identify or, when necessary, develop test methods suitable for acceptance as international Standards. Such test methods have to be capable of a rapid and reliable assessment of key
properties of fresh SCC on a construction site. At the same time, the testing equipment should be reliable, easily portable and inexpensive. The test procedure should be carried
out by a single operator and the test results have to be interpreted with a minimum of
training. Also, the results have to define and specify different GFRSCC mixes. One
primary application of these test methods would be in verification of compliance on sites
and in concrete production plants, if self- compacting concrete could be manufactured in
large quantities..

Applications of Artificial Neural Networks in Civil EngineeringPramey Zode
An artificial brain-like network based on certain mathematical algorithms developed using a numerical computing environment is called as an ‘Artificial Neural Network (ANN)’. Many civil engineering problems which need understanding of physical processes are found to be time consuming and inaccurate to evaluate using conventional approaches. In this regard, many ANNs have been seen as a reliable and practical alternative to solve such problems. Literature review reveals that ANNs have already being used in solving numerous civil engineering problems. This study explains some cases where ANNs have been used and its future scope is also discussed.

Assessment of Land Use Land Cover Classification through Geospatial Approach:...Premier Publishers
Earth's land use/land cover (LC/LU) classification provides valuable information particularly on natural resources, mapping and its monitoring. There is a significant change on LC/LU across the globe due to the climatic changes, rapid increase in population and over demand of economic natural resources. Remote Sensing (RS) satellite data with its synoptic view and multispectral data provides essential information in proper planning of LU/LC conditions of larger areas. The study aims to map and monitor the existing LU/LC classification scientifically using geospatial tools in database generation, analyses and information extraction. Thematic maps of the study area are prepared using satellite images in conjunction with collateral data Survey of India (SoI) toposheets, forest and wasteland maps. An attempt have been made to delineate the Level-I, Level-II and Level-III LU/LC classification system through NRSC guidelines (2011) using both Digital Image Processing (DIP) and Visual Image Interpretation Techniques (VIIT) by GIS software’s with limited Ground Truth Check (GTC). More accurate classification is observed in case of digital technique as compared to that of visual technique in terms of area statistics. The final results highlight the potentiality of geospatial technique in optimal and sustainable land use planning of natural resource and its management.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

17. Markov Chain Analysis (MCA)
On the basis of observed data between time periods, MCA computes
the probability that a cell will change from one land use type (state) to
another within a specified period of time.
The probability of moving from one state to another state is called a
transition probability.
Let set of states, S = { S1,S2, ……., Sn}.
Transition Probability
Matrix
where P = Markov transition probability matrix P
i, j = the land type of the first and second time period
Pij = the probability from land type i to land type j
Transition Area Matrix: is produced by multiplication of
each column in Transition Probability Matrix (P) by no. of
pixels of corresponding class in later image

28. Management Plan
Objectives considered
• To construct the small water and soil conservation structures at gullies.
• To participate rural peoples and stakeholder for prevent land degradation and
watershed management activities.
• Improvement of agriculture production.
• Use of Remote Sensing and GIS
Decision Rules decision rules are formulized for selection of sites for various soil and
water conservation structures as per the guidelines given by Integrated Mission for
Sustainable Development (IMSD, 1995), Indian National Committee on Hydrology
(INCOH)

30. Conclusions
•This research work demonstrates the ability of GIS and Remote
Sensing in capturing spatial-temporal dynamics of watershed.
•We believe that the study has demonstrated the usefulness of a
holistic model that combines Markov and CA models for watershed
changes.
•The combination of Markov and a simple CA filter was reasonably
accurate for projecting future land use land cover, since it produced
the overall accuracy of 76.22% which is more than US standard
acceptable accuracy 60%.
•We can prepare the future watershed management plan on the basis
of projected land use land cover of watershed dynamics by CA-
Markov Model.
