1. River training works include guide banks, marginal banks, spurs, and pitched islands that are constructed upstream of barrages and weirs. This is to ensure the river flows through the structure and to protect upstream lands and property from submergence.
2. Marginal banks are embankments on both sides of the river that maintain the river channel and prevent submergence of upstream areas. Spurs are fortified embankments built transverse to the banks that control the river's course and protect banks from erosion. Pitched islands artificially redistribute the river's force and sediment to attract and hold the channel.
Energy dissipaters are needed when water is released over a spillway to prevent scouring downstream. Various devices can be used, including baffle walls, deflectors, and staggered blocks, which reduce kinetic energy by converting it to turbulence and heat. Hydraulic jumps also dissipate energy by maintaining a high water level downstream. The type of dissipater used depends on the tailwater rating curve in relation to the jump height curve and the flow conditions. Stilling basins, sloping aprons, and roller buckets are suitable for different tailwater classifications.
This document provides guidelines for planning small bridge projects. It discusses important considerations for site selection such as river morphology, bridge location, and site conditions.

This information forms the basis for further site investigations and detailed design.
This document provides an overview of plastic analysis for structural elements. It discusses key concepts like plastic hinges, plastic section modulus, shape factors, and load factors. Plastic analysis is used to determine the ultimate or collapse load of a structure by considering the redistribution of moments that occurs after sections yield. Common failure mechanisms for determinate and indeterminate beams involve the formation of one or more plastic hinges. Methods for plastic analysis include the static/equilibrium method and kinematic/mechanism method. Examples are given for calculating the collapse load of simple structural configurations using these methods.
1) Open channel flow occurs when a surface of flow is open to the atmosphere, with only atmospheric pressure acting on the surface. Examples include rivers, streams, irrigation canals, and storm drains.
2) Open channel flows are classified based on whether the flow properties change over time (steady vs unsteady) or location (uniform vs non-uniform). Uniform steady flow has a constant depth at all locations and times.
3) The governing forces in open channel flows are inertia, viscosity, and gravity. Flow type is determined by the relative magnitudes of these forces, which can be laminar or turbulent depending on the Reynolds number, or subcritical or supercritical depending on the Froude number.

It provides equations to calculate the modified width and length of a footing based on the load eccentricities. It also provides the minimum footing dimensions required for a central column and describes how to calculate the ultimate bearing capacity of an eccentric footing using either the Hansen/Vesic or Meyerhof methods.
- There are four main methods to measure the load carrying capacity of piles: static methods, dynamic formulas, in-situ penetration tests, and pile load tests.
- The ultimate load capacity (Qu) of an individual pile or pile group equals the sum of the point resistance (Qp) at the pile tip and the shaft resistance (Qs) developed along the pile shaft through friction between the soil and pile.
- Meyerhof's method is commonly used to calculate Qp in sand based on the effective vertical pressure at the pile tip multiplied by the bearing capacity factor Nq.

Torsional behaviour of single cell box girder bridges.Hùng Thế
This thesis investigates the torsional behavior of single cell box girder bridges through finite element analysis. The author develops a finite element computer program to analyze orthotropic steel box girder bridges under uniform torsional loads. The program is verified by comparing results to theoretical solutions. The program is then used to study the stresses in several example bridges with different geometry and boundary conditions. The results demonstrate that torsional bending stresses, which are often ignored in design, are important to consider. The author makes recommendations for accounting for torsional deformations in bridge design based on the parametric studies.

This document provides an introduction to prestressed concrete, including:
1. The basic principles of prestressing concrete by applying compressive stresses that counteract tensile stresses from loads. This allows for smaller, more durable structures.
2. The two main methods are pre-tensioning, where strands are stressed before casting, and post-tensioning, where strands are tensioned after casting through ducts.
3. Common uses include precast beams, slabs, piles, and tanks, as well as in-situ construction like balanced cantilevers and segmental bridges. Design must account for losses in prestress over time from shrinkage, creep, and relaxation.

A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECTjpsjournal1
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
