The document discusses optimizing data transfer in service-oriented architectures. It proposes an approach called Promulgate that uses a hybrid orchestration and choreography model. Promulgate introduces proxy services that invoke actual web services on behalf of a centralized workflow engine. The proxies can cache and transfer data between each other to optimize transmission between services. The document evaluates Promulgate's use of data caching techniques like dynamic proxy deployment and SOAP compression to reduce redundant data transfer compared to a pure orchestration model. It describes the Promulgate architecture and actors, web service implementation using .NET and Axis, and SOAP compression using zipped SOAP. Experimental setup and configurations are also outlined to test Promulgate's performance over different network

A Centralized Network Management Application for Academia and Small Business ...ITIIIndustries
Software-defined networking (SDN) is reshaping the networking paradigm. Previous research shows that SDN has advantages over traditional networks because it separates the control and data plane, leading to greater flexibility through network automation and programmability. Small business and academia networks require flexibility, like service provider networks, to scale, deploy, and self-heal network infrastructure that comprises of cloud operating systems, virtual machines, containers, vendor networking equipment, and virtual network functions (VNFs); however, as SDN evolves in industry, there has been limited research to develop an SDN architecture to fulfil the requirements of small business and academia networks. This research proposes a network architecture that can abstract, orchestrate, and scale configurations based on academia and small business network requirements. Our results show that the proposed architecture provides enhanced network management and operations when combined with the network orchestration application (NetO-App) developed in this research. The NetO-App orchestrates network policies, automates configuration changes, secures container infrastructure, and manages internal and external communication between the campus networking infrastructure.

Software as a Service (SaaS) becomes in this decade the focus of many enterprises and research. SaaS
provides software application as Web based delivery to server many customers. This sharing of
infrastructure and application provided by Saas has a great benefit to customers, since it reduces costs,
minimizes risks, improves their competitive positioning, as well as seeks out innovative. SaaS application is
generally developed with standardized software functionalities to serve as many customers as
possible.However many customers ask to change the standardized provided functions according to their
specific business needs, and this can be achieve through the configuration and customization provided by
the SaaS vendor.Allowing many customers to change software configurations without impacting others
customers and with preserving security and efficiency of the provided services, becomes a big challenge to
SaaS vendors, who are oblige to design new strategies and architectures. Multi-tenancy (MT) architectures
allow multiple customers to be consolidated into the same operational system without changing anything in
the vendor source code. In this paper, we will present how the configuration can be done on an ERP web
application in a Multi-Tenancy SaaS environment.

This paper proposes a novel adaptive filter for removing salt and pepper noise from images using fuzzy logic. The filter has two stages: detection and filtering. In the detection stage, a 3x3 pixel window is used to identify noisy pixels. Pixels with maximum or minimum intensities are identified as salt or pepper noise. In the filtering stage, the detected noisy pixels are passed through merge scanning and histogram processing to remove noise while preserving image details. Simulation results on standard test images show the filter can remove up to 95% salt and pepper noise while maintaining high PSNR and processing speed.
This document summarizes a research paper on implementing heterogeneous interface mobile nodes in the NS2 network simulator.

The document aims to provide insights into widely used image smoothing approaches.
This document summarizes a proposed scheme called 2ACK for detecting routing misbehavior in mobile ad hoc networks (MANETs) that use the Optimized Link State Routing (OLSR) protocol. The 2ACK scheme involves sending two-hop acknowledgments in the opposite direction of the routing path to detect if any nodes are dropping packets instead of forwarding them as they should. Selfish nodes that refuse to forward packets can reduce network performance. The 2ACK scheme aims to identify these misbehaving nodes in order to improve routing reliability and efficiency in MANETs.
The document describes a proposed model for representing user profiles using ontologies for personalized web information gathering. The model uses both a world knowledge base (encoded from the Library of Congress Subject Headings) and a user's local instance repository to construct personalized ontologies representing the user's concept models and background knowledge. The proposed model is compared against existing benchmark models through experiments using a large standard dataset, and results show the proposed model improves web information gathering performance.
This document summarizes a study on using watermarking and security techniques for image broadcast. The study embeds a unique user ID watermark into images before distributing them in order to identify the source of any pirated images. The watermark is generated based on the user's encrypted ID and different keys are used for different users. When a pirated image is found, the watermark can be extracted to reveal the ID of the leaking user. The document describes the watermark embedding and extraction procedures and presents experimental results demonstrating the system's ability to extract watermarks after various image processing attacks.
1. The document presents a failure recovery scheme for mobile computing systems based on checkpointing and handoff count. It proposes taking checkpoints when the handoff count exceeds a threshold or the distance between mobile support stations exceeds a threshold.
2. The scheme aims to optimize both failure-free operation costs and failure recovery costs. Checkpoints are taken to minimize the amount of work lost after failures while limiting overhead during normal operation.
3. By delimiting the number of mobile support stations and distance from which recovery information needs to be collected, the proposed scheme aims to reduce recovery time and costs. Taking checkpoints based on handoff count and distance thresholds helps organize recovery information to facilitate efficient failure recovery.

1. The document discusses microservices as an emerging software architecture compared to service-oriented architectures (SOAs). Microservices break applications into independently deployable components that communicate over well-defined interfaces, allowing for improved scalability, quicker delivery, and greater autonomy compared to monolithic applications.
2. SOAs also break systems into services but take a centralized orchestration approach, while microservices emphasize decentralized coordination and independent deployment of each component service.
3. The benefits of microservices include improved scalability since each component can be scaled independently, quicker delivery through parallel development and deployment of components, and greater autonomy for teams in deploying and managing individual services.
Contemporary research challenges and applications of service oriented archite...Dr. Shahanawaj Ahamad
Service Oriented Architecture (SOA) is distributed architectural framework that provides service-based
solutions for improving the effectiveness of enterprise’s IT infrastructure. In this framework, technical and
business processes are implemented as services. A service is an independent software application that has been
designed to perform a specific function with emphasis on loose coupling between interacting services and their
components. SOA permits developers to utilize many of the resources from existing services to form the
distributed applications. This study has investigated to highlight the emerging issues of SOA such as service
structures advancement, requirements of evolution for current age applications like mobile-cloud, medical and
mechanism for interoperable operations. The paper also uncovers the practical application domains of SOA. It
has identified research attentions in these domains with detection of issues to carry further research to
overcome constraints in current scenarios.
WEB PORTAL INTEGRATION ARCHITECTURE APPROACHESijwscjournal
This document proposes a service-oriented architecture approach for web portal integration. It begins by describing a platform-independent integration architecture based on standards like UML, MOF, and XMI. This allows modeling integration independently of specific technologies. The document then discusses using WSMO as a specific implementation, describing how the platform-independent layers map to WSMO. It also discusses integrating agents and semantic web services using model transformations. Finally, it proposes additional "X-as-a-Service" layers that could be part of the architecture, like structure-as-a-service and process-as-a-service.
WEB PORTAL INTEGRATION ARCHITECTURE APPROACHESijwscjournal
Enterprise Modelling with Web portal integration architecture requires investment of advanced architectural thinking into definition of services before any development of services or service consumers can begin. Service Oriented Architecture (SOA) is gradually replacing monolithic architecture as the premier design principle for new business applications with its inherently systematic nature and capability. Earlier efforts of notable styles of SOA such as CORBA and XATMI have failed to be adopted as main stream projects because of demanding design process requirement with sense-making activities and even have been residing with the modern SOA or Web services middleware. In this paper it is aimed to incorporate sensemaking design activities with the proposed semantic web service based architecture. This paper tries to tackle the above problem by proposing a service-oriented architecture for web data and service integration. A gen-Spec architectural pattern has been suggested and adopted in order to tackle the problem.
Firstly, it proposes a service-oriented platform independent architecture and Secondly, it presents a specific deployment of such architecture for data and service integration on the web using semantic web services implemented with the WSMO (Web Services Modeling Ontology).

This document discusses application assembly using web services. It proposes that web services allow non-technical people to construct complex business software by assembling reusable software components/services. However, there are still challenges to address like how to take abstract concepts into software and ensure quality attributes like performance and security. The document presents a "separation continuum" model to understand the different elements that make up business systems from abstract requirements to software implementation. It argues that application assembly using independently developed web services is feasible if standards are followed and the right assembly tools are available.
The document discusses Service Oriented Architecture (SOA). It defines SOA as a collection of services that communicate with each other. These communication units are called services. Communication can involve simple data passing or coordinating an activity between two or more services. The document also discusses the evolution of SOA including the roles of XML, web services, and how SOA is defined with service requestors, providers, and registries. Key characteristics of SOA are also outlined such as being service-based, specification-based, combinable, reusable, and more. Past architectures like client-server and distributed architectures are also compared to SOA.
STUDY OF EVALUATION AND ASSESSMENT OF A CONSOLIDATED INTERNET SERVICE ARRANGE...IRJET Journal
This document presents a study that evaluates a framework for consolidating and integrating diverse internet services. The framework is designed to facilitate seamless integration of web services to address challenges of interoperability, scalability and reliability. The evaluation assesses the framework's architecture, design, components, performance, scalability, security, privacy and compliance through testing in real-world scenarios. It highlights the framework's applications in streamlining development and enhancing user experience. The goal of the study is to examine the framework's capabilities and limitations in serving as a foundation for next-generation integrated web services.
The aim of this paper is to propose a modeling framework, tailored to build efficient, elastic and autonomous applications from tasks and services. It includes integrated services to develop the software products, reusing on demand in-house services with specific requirements and flexible the representational state transfer (REST) services. The idea is to decouple authorization for reduced service dependency and to provide a possibility for developing the whole application by increasing the existing application flexibility. Based on the fact that there are different web application platforms that serve to offer services to users but they are not integrated; we propose a framework with high flexibility degree, especially integrating the most used services such: e-learning, administrative, and library services, as University services are concern.

Architecture evolution for automation and network programmabilityEricsson
http://www.ericsson.com/review
Automation and network programmability are key concepts in the evolution of telecom networks. Architecture designed with high degrees of automation and network programmability can rapidly adapt to emerging requirements, and as such improve operational efficiency and time to market for new services.
This is a presentation of a research paper on comparative study of Component based Software Engineering and Service Oriented Architecture. It covers technologies of both paradigms as well as technical discussions and justifications on SOA. It also covers modern components.
A distributed system can be viewed as an environment in which, number of computers/nodes are connected and resources are shared among these computers/nodes. But unfortunately, distributed systems often face the problem of traffic, which can degrade the performance of the system. Traffic management is used to improve scalability and overall system throughput in distributed systems using Software Defined Network (SDN) based systems. Traffic management improves system performance by dividing the work traffic effectively among the participating computers/nodes. Many algorithms were proposed for traffic management and their performance is measured based on certain parameters such as response time, resource utilization, and fault tolerance. Traffic management algorithms are broadly classified into two categories- scheduling and machine learning traffic management. This work presents the study of performance analysis of traffic management algorithms. This analysis can further help in the design of new algorithms. However, when multiple servers are assigned to compile the mysterious code, different kinds of techniques are used. One common example is traffic management. The processes are managed based on power efficiency, networking bandwidth, Processor speed. The desired output will again send back to the developer. If multiple programs have to be compiled then appropriate technique such as scheduling algorithm is used. So the compilation process becomes faster and also the other process can get a chance to compile. SDN based clustering algorithm based on Simulated Annealing whose main goal is to increase network lifetime while maintaining adequate sensing coverage in scenarios where sensor nodes produce uniform or non-uniform data traffic.
1. The document discusses Service Oriented Architecture (SOA) and its key characteristics.
2. It compares SOA to past architectures like application architecture and enterprise architecture.
3. The core characteristics of SOA include promoting loose coupling, reuse, and interoperability through services based on open standards.
Electrically small antennas: The art of miniaturizationEditor IJARCET
We are living in the technological era, were we preferred to have the portable devices rather than unmovable devices. We are isolating our self rom the wires and we are becoming the habitual of wireless world what makes the device portable? I guess physical dimensions (mechanical) of that particular device, but along with this the electrical dimension is of the device is also of great importance. Reducing the physical dimension of the antenna would result in the small antenna but not electrically small antenna. We have different definition for the electrically small antenna but the one which is most appropriate is, where k is the wave number and is equal to and a is the radius of the imaginary sphere circumscribing the maximum dimension of the antenna. As the present day electronic devices progress to diminish in size, technocrats have become increasingly concentrated on electrically small antenna (ESA) designs to reduce the size of the antenna in the overall electronics system. Researchers in many fields, including RF and Microwave, biomedical technology and national intelligence, can benefit from electrically small antennas as long as the performance of the designed ESA meets the system requirement.
This document provides a comparative study of two-way finite automata and Turing machines. Some key points:
- Two-way finite automata are similar to read-only Turing machines in that they have a finite tape that can be read in both directions, but cannot write to the tape.
- Turing machines have an infinite tape that can be read from and written to, allowing them to recognize recursively enumerable languages.
- Both models are examined in their ability to accept the regular language L={anbm|m,n>0}.
- The time complexity of a two-way finite automaton for this language is O(n2) due to making two passes over the
This document analyzes and compares the performance of the AODV and DSDV routing protocols in a vehicular ad hoc network (VANET) simulation. Simulations were conducted using NS-2, SUMO, and MOVE simulators for a grid map scenario with varying numbers of nodes. The results show that AODV performed better than DSDV in terms of throughput and packet delivery fraction, while DSDV had lower end-to-end delays. However, neither protocol was found to be fully suitable for the highly dynamic VANET environment. The document concludes that further work is needed to develop improved routing protocols optimized for VANETs.
This document discusses the digital circuit layout problem and approaches to solving it using graph partitioning techniques. It begins by introducing the digital circuit layout problem and how it has become more complex with increasing circuit sizes. It then discusses how the problem can be decomposed into subproblems using graph partitioning to assign geometric coordinates to circuit components. The document reviews several traditional approaches to solve the problem, such as the Kernighan-Lin algorithm, and discusses their limitations for larger circuit sizes. It also discusses more recent approaches using evolutionary algorithms and concludes by analyzing the contributions of various approaches.
This document summarizes various data mining techniques that have been used for intrusion detection systems.

The goal is to integrate the lines to better utilize space and manpower while meeting manufacturing standards.
This document summarizes research on the exposure of microwaves from cellular networks. It describes how microwaves interact with biological systems and discusses measurement techniques and safety standards regarding microwave exposure. While some studies have alleged health hazards from microwaves, independent reviews by health organizations have found no evidence that exposure to microwaves below international safety limits causes harm. The document concludes that with precautions like limiting exposure time and using phones with lower SAR ratings, microwaves from cell phones pose minimal health risks.
This document summarizes a research paper that examines the effect of feature reduction in sentiment analysis of online reviews. It uses principle component analysis to reduce the number of features (product attributes) from a dataset of 500 camera reviews labeled as positive or negative. Two models are developed - one using the original set of 95 product attributes, and one using the reduced set. Support vector machines and naive Bayes classifiers are applied to both models and their performance is evaluated to determine if classification accuracy can be maintained while using fewer features. The results show it is possible to achieve similar accuracy levels with less features, improving computational efficiency.
This document provides a review of multispectral palm image fusion techniques. It begins with an introduction to biometrics and palm print identification. Different palm print images capture different spectral information about the palm. The document then reviews several pixel-level fusion methods for combining multispectral palm images, finding that Curvelet transform performs best at preserving discriminative patterns. It also discusses hardware for capturing multispectral palm images and the process of region of interest extraction and localization. Common fusion methods like wavelet transform and Curvelet transform are also summarized.
This document describes a vehicle theft detection system that uses radio frequency identification (RFID) technology. The system involves embedding an RFID chip in each vehicle that continuously transmits a unique identification signal. When a vehicle is stolen, the owner reports it to the police, who upload the vehicle's information to a central database. Police vehicles are equipped with RFID receivers. If a stolen vehicle passes within range of a receiver, the receiver detects the vehicle's ID signal and displays its details on a tablet. This allows police to quickly identify and recover stolen vehicles. The system aims to make it difficult for thieves to hide a vehicle's identity and allows vehicles to be tracked globally wherever the detection system is implemented.
This document discusses and compares two techniques for image denoising using wavelet transforms: Dual-Tree Complex DWT and Double-Density Dual-Tree Complex DWT. Both techniques decompose an image corrupted by noise using filter banks, apply thresholding to the wavelet coefficients, and reconstruct the image. The Double-Density Dual-Tree Complex DWT yields better denoising results than the Dual-Tree Complex DWT as it produces more directional wavelets and is less sensitive to shifts and noise variance. Experimental results on test images demonstrate that the Double-Density method achieves higher peak signal-to-noise ratios, especially at higher noise levels.
This document compares the k-means and grid density clustering algorithms. It summarizes that grid density clustering determines dense grids based on the densities of neighboring grids, and is able to handle different shaped clusters in multi-density environments. The grid density algorithm does not require distance computation and is not dependent on the number of clusters being known in advance like k-means. The document concludes that grid density clustering is better than k-means clustering as it can handle noise and outliers, find arbitrary shaped clusters, and has lower time complexity.
This document proposes a method for detecting, localizing, and extracting text from videos with complex backgrounds. It involves three main steps:
1. Text detection uses corner metric and Laplacian filtering techniques independently to detect text regions. Corner metric identifies regions with high curvature, while Laplacian filtering highlights intensity discontinuities. The results are combined through multiplication to reduce noise.
2. Text localization then determines the accurate boundaries of detected text strings.
3. Text binarization filters background pixels to extract text pixels for recognition. Thresholding techniques are used to convert localized text regions to binary images.
The method exploits different text properties to detect text using corner metric and Laplacian filtering. Combining the results improves
This document describes the design and implementation of a low power 16-bit arithmetic logic unit (ALU) using clock gating techniques. A variable block length carry skip adder is used in the arithmetic unit to reduce power consumption and improve performance. The ALU uses a clock gating circuit to selectively clock only the active arithmetic or logic unit, reducing dynamic power dissipation from unnecessary clock charging/discharging. The ALU was simulated in VHDL and synthesized for a Xilinx Spartan 3E FPGA, achieving a maximum frequency of 65.19MHz at 1.98mW power dissipation, demonstrating improved performance over a conventional ALU design.
This document describes using particle swarm optimization (PSO) and genetic algorithms (GA) to tune the parameters of a proportional-integral-derivative (PID) controller for an automatic voltage regulator (AVR) system. PSO and GA are used to minimize the objective function by adjusting the PID parameters to achieve optimal step response with minimal overshoot, settling time, and rise time. The results show that PSO provides high-quality solutions within a shorter calculation time than other stochastic methods.
This document discusses implementing trust negotiations in multisession transactions. It proposes a framework that supports voluntary and unexpected interruptions, allowing negotiating parties to complete negotiations despite temporary unavailability of resources. The Trust-x protocol addresses issues related to validity, temporary loss of data, and extended unavailability of one negotiator. It allows a peer to suspend an ongoing negotiation and resume it with another authenticated peer. Negotiation portions and intermediate states can be safely and privately passed among peers to guarantee stability for continued suspended negotiations. An ontology is also proposed to provide formal specification of concepts and relationships, which is essential in complex web service environments for sharing credential information needed to establish trust.
This document discusses and compares various nature-inspired optimization algorithms for resolving the mixed pixel problem in remote sensing imagery, including Biogeography-Based Optimization (BBO), Genetic Algorithm (GA), and Particle Swarm Optimization (PSO). It provides an overview of each algorithm, explaining key concepts like migration and mutation in BBO. The document aims to prove that BBO is the best algorithm for resolving the mixed pixel problem by comparing it to other evolutionary algorithms. It also includes figures illustrating concepts like the species model and habitat in BBO.
This document discusses principal component analysis (PCA) for face recognition. It begins with an introduction to face recognition and PCA. PCA works by calculating eigenvectors from a set of face images, which represent the principal components that account for the most variance in the image data. These eigenvectors are called "eigenfaces" and can be used to reconstruct the face images. The document then discusses how the system is implemented, including preparing a face database, normalizing the training images, calculating the eigenfaces/principal components, projecting the face images into this reduced space, and recognizing faces by calculating distances between projected test images and training images.
This document summarizes research on using wireless sensor networks to detect mobile targets. It discusses two optimization problems: 1) maximizing the exposure of the least exposed path within a sensor budget, and 2) minimizing sensor installation costs while ensuring all paths have exposure above a threshold. It proposes using tabu search heuristics to provide near-optimal solutions. The research also addresses extending the models to consider wireless connectivity, heterogeneous sensors, and intrusion detection using a game theory approach. Experimental results show the proposed mobile replica detection scheme can rapidly detect replicas with no false positives or negatives.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
