The document discusses the development of a storm water forecast system for Singapore using distributed hydrological modeling and radar rainfall data. Key points include:
- A distributed hydrological model (MIKE SHE) using radar rainfall data provided better water level forecasts than previous lumped models using rain gauge data alone, enabling lead times of 10-70 minutes.
- Validation against 11 rainfall-runoff events showed the distributed radar-based model produced more accurate runoff hydrographs and water level forecasts than the previous rain gauge-based model.
- The best forecast performance was achieved for heavy to moderate rainfall events with wide spread coverage, occurring away from the radar location with no attenuation effects and steady storm movement speeds. These types of

Cities across the world are facing significant water system challenges related to urbanisation and climate change. To advance the concept of integrated real-time control of water systems, an innovative generalised technology framework has been developed as part of a collaborative research effort. The framework facilitates the global acceptance and improved implementation of smart real-time control of water systems which offers a proven, cost effective alternative to the conventional approach of increasing system capacity.
The core of the framework is a generalised data platform which can be used within all water domains. This platform integrates time series data and spatial data with numerical models, and offers a broad suite of generalised tools for data processing and reporting. Data tools can be executed as automated workflows that replace tedious and error prone manual tasks. A key element of the work is the development of fast and accurate surrogate models of complex physical systems, complementing standard deterministic high-fidelity models adapted to observations in real time in order to ensure efficiency and performance of the automated model predictive control algorithms. A second element is the utilisation of local area weather radar data, since distributed rainfall observations and accurate forecasts are essential for optimising the use of the system capacity.
This work focuses on the impacts of using the new smart real-time control of water systems framework on a full scale, real world example using the urban drainage system of the city of Aarhus, Denmark as a testbed.

Climate variability has been, and continues to be the principal source of fluctuations in global food production in the arid and semi-arid tropical countries of the developing world. Favourable weather is essential for good harvests. Weather abnormalities like cyclones, droughts, hailstorms, frost, high winds, extreme temperature and insufficient photosynthetic radiation etc., may generally lead to very low or even no yields. Hence, characterization of agro climates is a pre-requisite to know the potential of a region, especially under dryland conditions for improving and stabilizing the productivity
Climate and crop modelling approach-Cropping advisories based on seasonal for...ICRISAT
In a pilot study conducted in South India, farmers who followed the cropping advisory derived from climate and crop simulation modeling earned 20% more than those who did not heed the advice.A majority of the farming community in
Hussainapuram, Kurnool, Andhra Pradesh, India, live below the poverty line. Over 50% of the cultivators hold less than two hectares of dryland. Twice in every five years the village experiences drought. Recurrent droughts force migration to nearby cities for employment. In this region the deep black soils are deficient in major and micro nutrients like nitrogen, phosphorus, sulfur, boron and zinc. Cotton, groundnut, sunflower and chickpea are the major crops in the region. Cotton growers have been the worst hit by changing rainfall patterns.

WKS401 Deploy a Deep Learning Framework on Amazon ECS and EC2 Spot InstancesAmazon Web Services
Deep learning is an implementation of machine learning that uses neural networks to solve difficult and complex problems, such as computer vision, natural language processing, and recommendations. Due to the availability of deep learning libraries and frameworks, developers have the ability to enhance the capabilities of their applications and projects.
In this workshop, you learn how to build and deploy a powerful deep learning framework called MXNet on containers. The portability and resource management benefit of containers means developers can focus less on infrastructure and more on building. The labs start by demonstrating the automation capabilities of AWS CloudFormation to stand up core infrastructure; as an added bonus, you use Spot Fleet to leverage the cost benefits of using Spot Instances, especially for developer environments. Then, you walk through creating an MXNet container in Docker and deploying it with Amazon ECS. Finally, you walk through an image classification demo of MXNet to validate that everything is working as expected.

As Scotland’s principal environmental regulator, SEPA is responsible for ensuring compliance with environmental quality standards. The implementation of the Water Framework Directive (WFD), which focuses on the ecological and chemical status of water bodies, combined with a rapidly expanding aquaculture sector, means risk-appropriate modelling of the impacts from fish farms is required. Using a combination of small scale highly simplified modelling, large scale, low resolution screening tools, and relatively complex waterbody scale hydrodynamic modelling and particle tracking , we can obtain a better understanding of the risks posed to the marine environment, influence strategic policy decisions and support sustainable future farm growth and development.
Presented at the DHI Ireland Symposium 2018.
This presentation will cover the extensive application of hydraulic modelling on the national Catchment-based Flood Risk Assessment & Management (CFRAM) programme, as well as discussing the likely future modelling requirements for the detailed development of over 100 flood relief schemes programmed over the coming decade.

Using numerical modelling to regulate a growing aquaculture industry. Ted Sch...Stephen Flood
Scotland is currently the largest producer of Atlantic salmon in the EU, and the third largest globally. Exports have doubled in the past decade to nearly £1 billion per annum, and the Scottish Government has specified targets for further expansion. SEPA is working with fish-farmers to help them comply with environmental legislation and to ensure that this growth is sustainable.
Modelling is used to predict the environmental impact of organic material and medicines, and to determine appropriate locations and biomass limits for fish-farms. Traditionally, these farms have been assessed and licensed in isolation, but numerical modelling is increasingly being used to investigate larger scale impacts, cumulative effects, and hydrodynamic connectivity between farms.
MIKE21 models of several water bodies have been developed, with the Particle Tracking module used to predict the spatial and temporal variation of SLICE, a sea-lice medicine. A sub-model of the Scottish Shelf Model developed by Marine Scotland has been converted from FVCOM and is being used to develop a screening tool for assessing the interaction between farms in the Highlands and Islands. By adopting risk-based modelling over a range of scales, SEPA can obtain a better understanding of the environmental impact of fish-farms, influence strategic policy decisions and support sustainable growth of the aquaculture industry.

FAST Danube – Hydraulic and sediment transport modelling with MIKE 21 FM mode...Stephen Flood
The objective of the FAST Danube project is to propose navigation improvement solutions on the Romanian-Bulgarian common sector of the River Danube. The proposed technical solutions would ensure that the required navigation parameters (navigation channel width, depth and bend radius) are achieved at the specified lowest navigation water levels. This would enable safe navigation and transport activities on the Romanian-Bulgarian common sector of the River Danube throughout the entire year.
MIKE 21 FM hydrodynamic and sediment transport models have been developed to help understand the behaviour of the river and the reasons for the changes in river morphology, which result in constraints to navigation at the critical locations. The MIKE 21 FM models are required to support the selection of solution options by providing a first assessment of the relative performance of navigation improvement solutions in maintaining the required navigation fairway parameters. In addition, the MIKE 21 FM models will also provide outputs to support the assessment of the potential impacts of the solutions on navigation conditions and on the river environment. Furthermore, the models will also be used as tools in future management of the river in the project area.
This presentation will focus on the numerical modelling conducted with the MIKE 21 FM model within the FAST Danube project, and how the MIKE 21 FM models are used in the development of navigation improvement solutions and options appraisal process.

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.
HEAP SORT ILLUSTRATED WITH HEAPIFY, BUILD HEAP FOR DYNAMIC ARRAYS.
Heap sort is a comparison-based sorting technique based on Binary Heap data structure. It is similar to the selection sort where we first find the minimum element and place the minimum element at the beginning. Repeat the same process for the remaining elements.
Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
