 Fabric layer: - Grids provide access to different resource types such as
compute, storage and network resource, code repository, etc. Grids
usually rely on existing fabric components, for instance, local
resource managers.
 Connectivity layer:-It defines core communication and authentication
protocols for easy and secure network transactions. The GSI (Grid
Security Infrastructure) protocol underlies every Grid transaction.
 Resource layer: - It defines protocols for the publication, discovery,
negotiation, monitoring, accounting and payment of sharing
operations on individual resources. The GRAM (Grid Resource Access
and Management) protocol is used for allocation of computational
resources and for monitoring and control of computation on those
resources, and Grid FTP for data access and high-speed data transfer.
 Collective layer: - It captures interactions across collections of
resources, directory services such as MDS (Monitoring and Discovery
Service) allows for the monitoring and discovery of VO resources.
 Application layer: - It comprises whatever user applications built on
top of the above protocols and APIs and operate in VO environments.
Two examples are Grid workflow systems, and Grid portals.

DISTRIBUTED AND BIG DATA STORAGE MANAGEMENT IN GRID COMPUTINGijgca

Big data storage management is one of the most challenging issues for Grid computing environments, since large amount of data intensive applications frequently involve a high degree of data access locality. Grid applications typically deal with large amounts of data. In traditional approaches high-performance computing consists dedicated servers that are used to data storage and data replication. In this paper we present a new mechanism for distributed and big data storage and resource discovery services. Here we proposed an architecture named Dynamic and Scalable Storage Management (DSSM) architecture in grid environments. This allows in grid computing not only sharing the computational cycles, but also share the storage space. The storage can be transparently accessed from any grid machine, allowing easy data sharing among grid users and applications. The concept of virtual ids that, allows the creation of virtual spaces has been introduced and used. The DSSM divides all Grid Oriented Storage devices (nodes) into multiple geographically distributed domains and to facilitate the locality and simplify the intra-domain storage management. Grid service based storage resources are adopted to stack simple modular service piece by piece as demand grows. To this end, we propose four axes that define: DSSM architecture and algorithms description, Storage resources and resource discovery into Grid service, Evaluate purpose prototype system, dynamically, scalability, and bandwidth, and Discuss results. Algorithms at bottom and upper level for standardization dynamic and scalable storage management, along with higher bandwidths have been designed.

Security of software defined networks: evolution and challengesInternational Journal of Reconfigurable and Embedded Systems

In software-defined networking (SDN), network traffic is managed by software controllers or application programming interfaces (APIs) rather than hardware components. It differs from traditional networks, which use switches and routers to control traffic. Using SDN, you can create and control virtual networks or traditional hardware networks. Furthermore, OpenFlow allows network administrators to control exact network behavior through centralized control of packet forwarding. For these reasons, SDN has advantages over certain security issues, unlike traditional networks. However, most of the existing vulnerabilities and security threats in the traditional network also impact the SDN network. This document presents the attacks targeting the SDN network and the solutions that protect against these attacks. In addition, we introduce a variety of SDN security controls, such as intrusion detection systems (IDS)/intrusion prevention system (IPS), and firewalls. Towards the end, we outline a conclusion and perspectives.

Process Parameter Optimization for Minimizing Springback in Cold Drawing Proc...Journal of Soft Computing in Civil Engineering

In tube drawing process, a tube is pulled out through a die and a plug to reduce its diameter and thickness as per the requirement. Dimensional accuracy of cold drawn tubes plays a vital role in the further quality of end products and controlling rejection in manufacturing processes of these end products. Springback phenomenon is the elastic strain recovery after removal of forming loads, causes geometrical inaccuracies in drawn tubes. Further, this leads to difficulty in achieving close dimensional tolerances. In the present work springback of EN 8 D tube material is studied for various cold drawing parameters. The process parameters in this work include die semi-angle, land width and drawing speed. The experimentation is done using Taguchi’s L36 orthogonal array, and then optimization is done in data analysis software Minitab 17. The results of ANOVA shows that 15 degrees die semi-angle,5 mm land width and 6 m/min drawing speed yields least springback. Furthermore, optimization algorithms named Particle Swarm Optimization (PSO), Simulated Annealing (SA) and Genetic Algorithm (GA) are applied which shows that 15 degrees die semi-angle, 10 mm land width and 8 m/min drawing speed results in minimal springback with almost 10.5 % improvement. Finally, the results of experimentation are validated with Finite Element Analysis technique using ANSYS.

"Feed Water Heaters in Thermal Power Plants: Types, Working, and Efficiency G...Infopitaara

A feed water heater is a device used in power plants to preheat water before it enters the boiler. It plays a critical role in improving the overall efficiency of the power generation process, especially in thermal power plants. 🔧 Function of a Feed Water Heater: It uses steam extracted from the turbine to preheat the feed water. This reduces the fuel required to convert water into steam in the boiler. It supports Regenerative Rankine Cycle, increasing plant efficiency. 🔍 Types of Feed Water Heaters: Open Feed Water Heater (Direct Contact) Steam and water come into direct contact. Mixing occurs, and heat is transferred directly. Common in low-pressure stages. Closed Feed Water Heater (Surface Type) Steam and water are separated by tubes. Heat is transferred through tube walls. Common in high-pressure systems. ⚙️ Advantages: Improves thermal efficiency. Reduces fuel consumption. Lowers thermal stress on boiler components. Minimizes corrosion by removing dissolved gases.

Development of MLR, ANN and ANFIS Models for Estimation of PCUs at Different ...Journal of Soft Computing in Civil Engineering

Passenger car unit (PCU) of a vehicle type depends on vehicular characteristics, stream characteristics, roadway characteristics, environmental factors, climate conditions and control conditions. Keeping in view various factors affecting PCU, a model was developed taking a volume to capacity ratio and percentage share of particular vehicle type as independent parameters. A microscopic traffic simulation model VISSIM has been used in present study for generating traffic flow data which some time very difficult to obtain from field survey. A comparison study was carried out with the purpose of verifying when the adaptive neuro-fuzzy inference system (ANFIS), artificial neural network (ANN) and multiple linear regression (MLR) models are appropriate for prediction of PCUs of different vehicle types. From the results observed that ANFIS model estimates were closer to the corresponding simulated PCU values compared to MLR and ANN models. It is concluded that the ANFIS model showed greater potential in predicting PCUs from v/c ratio and proportional share for all type of vehicles whereas MLR and ANN models did not perform well.

Grid protocol architecture

1. Prof. Neeraj Bhargava Pooja Dixit Department of Computer Science School of Engineering & System Sciences MDS, University Ajmer, Rajasthan, India 1

2.  Grids provide protocols and services at five different layers as identified in the Grid protocol architecture. These are five layers in grid architecture. Grid Protocol Architecture 2

3.  Fabric layer: - Grids provide access to different resource types such as compute, storage and network resource, code repository, etc. Grids usually rely on existing fabric components, for instance, local resource managers.  Connectivity layer:-It defines core communication and authentication protocols for easy and secure network transactions. The GSI (Grid Security Infrastructure) protocol underlies every Grid transaction.  Resource layer: - It defines protocols for the publication, discovery, negotiation, monitoring, accounting and payment of sharing operations on individual resources. The GRAM (Grid Resource Access and Management) protocol is used for allocation of computational resources and for monitoring and control of computation on those resources, and Grid FTP for data access and high-speed data transfer.  Collective layer: - It captures interactions across collections of resources, directory services such as MDS (Monitoring and Discovery Service) allows for the monitoring and discovery of VO resources.  Application layer: - It comprises whatever user applications built on top of the above protocols and APIs and operate in VO environments. Two examples are Grid workflow systems, and Grid portals. Grid Protocol Architecture 3
