Subscription based control system to automate management of events for robotsdbpublications
In Industrial Robots, a human machine interfaces (HMI) provide means to command and control robots for various purposes. Generally, this is implemented in a reactive manner by using polling (or pull) methodology to manage the events. This methodology restricts the possibilities of automation for reacting to events thus requires a human operator to poll and react to the events based on the skill of the human operator. This sometimes causes non-optimal or wrong responses. This paper proposes a design methodology to dynamically tap the events using a subscription based control system for event based management of robots. This design enables the client to be light-weight, cost effective and makes the responses more reliable. The paper also scrutinizes the alternative design options using semantic web for multirobot coordinative activities.

Enhancement in Web Service ArchitectureIJERA Editor
Web services provide a standard means of interoperating between different software applications, running on a
variety of platforms and/or frameworks. Web services are increasingly used to integrate and build business
application on the internet. Failure of web services is not acceptable in many situations such as online banking,
so fault tolerance is a key challenge of web services. This paper elaborates the concept of web service
architecture and its enhancement. Traditional web service architecture lacks facilities to support fault tolerance.
To better cope with the fundamental issues of the traditional client-server based web service architecture, peer to
peer web service architecture have been introduced. The purpose of this paper is to elaborate the architecture,
construction methods and steps of web services and possible weaknesses in scalability and fault tolerance in
traditional client server architecture and a solution for that, peer to peer web service technology has evolved.

MULTIVIEW SOA : EXTENDING SOA USING A PRIVATE CLOUD COMPUTING AS SAAS AND DAASijseajournal
This work is based on two major areas, the Multiview Service Oriented Architecture and the combination between the computing cloud and MV-SOA. Thus, it is suggested to extend firstly the service oriented architecture (SOA) into an architecture called MV-SOA by adding two components, the Multiview service generator, whose role is to transform the classic service into Multiview service, and the data base, this component seeks to stock all of consumer service information. It is also suggested to combine the computing cloud and Multiview Service Oriented Architecture MVSOA. To reach such combination, the
MVSOA architecture was taken and we added to the client-side a private cloud in SaaS and DaaS.
Performance Evaluation of Web Services In Linux On MulticoreCSCJournals
Contemporary Business requires the ability to seamlessly exchange information between internal
business units, customers, and partner, is vital for success. Most organizations employ a variety of
different applications to store and exchange data in dissimilar way and therefore cannot “communicate” to
one another productively [1]. Service Oriented Architecture (SOA) components provide services to other
components via communication protocols typically over a network [2].The technologies like DCOM, RMI,
COBRA, Web Services etc. are developed using SOA, which contributed best to fulfill requirements to
some extent, but components result from these technologies are mostly either language specific or
platform specific,[3]. The services or components developed for one platform may not be able to
communicate and reusable in other platform, as they are mostly language specific or platform specific.
“World Wide Web Consortium (W3C) International community to develop web standards” issued WS-*
specifications for programming language vendors for Web services, which confirms a standard means of
interoperating between different software applications running on a variety of platforms or frameworks
[4][5]. This paper tests web services performance gain along with interoperability, reusability by using
“NAS Parallel Benchmarks (NPB)” set of program [6] developed by NASA Advanced Supercomputing
Division to evaluate the performance of supercomputers.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

REpresentational State Transfer
Roy Fielding (2000)’s dissertation
An architectural style!
Resource oriented
Resources identified by URIs (Uniform Resource Identifiers)
Stateless messages which are self descriptive
Resources - Conceptual target of a Hyperref
Resources - Retrieved as complete representation of concepts
JavaOne India 2013
5. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
REpresentational State Transfer
Multiple representations of data
XML, Plain Text, HTML, RSS, JSON...
All resources mapped to HTTP methods
GET, POST, PUT, DELETE (Universal Verbs)
URIs - Nouns
Transport level security!
A few DOs and DON’Ts on HTTP leads to REST style easily!
JavaOne India 2013
6. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
Motivation
Design a robust e-voting system
Using most of the existing infrastructure (ATMs)
Minimize costs to governments
Highly scalable
Real-time Performance
Security and Voting guidelines to be adhered to!
JavaOne India 2013
7. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
Why using ATMs?
Highly scalable infrastructure already setup
Good on-going research, to include Non-Financial Services
Few modifications to business logic and database schema of
Banks can result in incorporating several Non-Financial
Services
Issues to be addressed:
Increased load on Bank Servers
Heavy traffic flow all the way
Adherence to Banking and Voting process related issues
Security!
User Interface
JavaOne India 2013
8. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
Architecture
Available Options
Simple extension to existing Architecture
Web Services
Simple extension isn’t effective!
Existing Architecture not easily known
Not an easy task
Huge loads on servers
Architecture is not same across all Banks
Web Services chosen because they can be plugged in
anywhere without much difficulty!

Why REST over SOAP/WSDL?
REST is cleaner than SOAP
Safe encapsulation of Legacy systems
REST isn’t any obscure, its the way Web works aided with
some rules!
Plain Text Data exchange
Not many standards to follow other than basic HTTP
methods!

JavaOne India 2013
13. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
Uncovering the e-Voting System
1 Voter requests for One Time Password (OTP) and List of
Candidates on SMS
2 User authenticates himself with ATM PIN and OTP
3 Interface to capture Votes for all elections is loaded
4 User enters the corresponding Candidate ID in the available
TextBox along with Voting PIN
5 Vote Count for corresponding candidate is updated
6 Instant result availability - key feature!

e-Voting : Interaction among Web Services
JavaOne India 2013
15. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
Advantages of using REST style
Scalable Components
Simple interfaces
Independently deployable
Secure
Easy real-time deployment
Real-time performance
Multiple data formats
Lesser loads on servers
JavaOne India 2013
16. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
Scalability
REST encourages using good practices for Scalability
Each Web Service can be deployed on a separate server
Ensures the services aren’t affected by performance
bottlenecks
Very close to real-time deployment
Easier Functional Scalability
More Non-Functional Services can be added to the ATM
Terminals
JavaOne India 2013
17. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
Security
Security a serious issue!
ATMs in private networks of Banks
All messages transferred via SSL (Secure Sockets Layer)
Messages required to be transferred directly between the
Election Authority and the Client are encrypted using a shared
key (2048 bit) between ATM Terminal Client and Election
Authority
Bank merely forwards the messages to Election Authority but
will NOT be able to read it!
JavaOne India 2013
18. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
Real-time Deployment
Web Services can be deployed on different servers as
interfaces are well-defined
Supports deployment on distributed servers
Real-time performance because no much interaction latency
Banks already have well set-up infrastructure and setting up a
robust infrastructure for Election Authority can handle huge
requests, which is a typical scenario of an e-Voting system
JavaOne India 2013
19. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
Multiple Data Formats
Parsing XML is a costlier process
SOAP/WSDL allows only XML for interactions
XML, JSON, HTML, Plain Text are allowed in REST
Parsing one data format to other not required, as the Web
services can agree on a single data format as simple as Plain
Text for simplicity
JavaOne India 2013
20. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
Load on Servers
In an application where large number of requests are to be
served, storing state information can lead to performance
bottlenecks
e-Voting is a system where almost 100000 clients may perform
some operation plus the normal financial transactions on ATM
terminals are also to be satisfied
In REST, the servers are not required to maintain state of
clients
Messages contain necessary information required for a Web
Service, including but not limited to state of the client
JavaOne India 2013
21. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
A Small Demonstration
All Web Services hosted on one machine only, this is just for
understanding of the application
JavaOne India 2013
22. Agenda Introduction The Idea Implementing the RESTful Way Demonstration Conclusion
Winding it up...
REST style can facilitate many Non-Financial Services on
ATM Terminals
Performance guaranteed
Scalable, Real-time Deployment of Web Services to
accomplish several additional tasks on ATMs
Using REST and making excellent use of existing ATM-Bank
infrastructure, a robust e-Voting system can be developed
“Statelessness means that the client’s state is not maintained
by server, which states that the performance bottlenecks don’t
arise!”
