Office automation

Bibliography: p. 100-104.Office automation systems have become an essential tool for the operation of the modern office. With the emphasis of a modern office being placed on efficiency and ease of communication, office automation systems have become the backbone of successful businesses. COSNET is a prototype office automation system designed and implemented at the Department of the University of Cape Town and runs on Personal Computers that are linked to a NCR UNIX TOWER, which acts as the host. This dissertation investigates the different facilities supported by some of the office automation systems compared in this thesis, and describes the COSNET features. This prototype office automation system supports many of the facilities that are supported by large office automation systems. COSNET allows the user to define any MS-DOS based editor or word processor, and uses a simple editor for the creation of mail. The electronic filing facility allows documents to be created, filed, retrieved and deleted, and thus provides the users with the necessary features for document exchange. A user may set access permissions to each of his documents and may grant other users either read or write access to a specific document. The mail facility lets the user read, file, forward, delete and print a message, and supports classification of mail. A calendar facility is used as an electronic diary and stores all the user's schedules. These schedules may be viewed in either daily, weekly and monthly display modes. Read and write access to the calendar can be set by the user, in order to allow other users to manipulate his schedules. Any MS-DOS based application software can be added to COSNET. This facility allows the COSNET user to configure the office automation system to simulate the office environment. COSNET thus supports most of the necessary features required by an office automation system

Resolving Non-Determinism in Choreographies

Resolving non-deterministic choices of choreographies is a crucial task. We introduce a novel notion of realisability for choreographies –called whole-spectrum implementation– that rules out deterministic implementations of roles that, no matter which context they are placed in, will never follow one of the branches of a non-deterministic choice. We show that, under some conditions, it is decidable whether an implementation is whole-spectrum. As a case study, we analyse the POP protocol under the lens of whole-spectrum implementation

Process Driven Software Engineering Environments

Software development organizations have begun using Software Engineering Environments (SEEs) with the goal of enhancing the productivity of software developers and improving the quality of software products. The encompassing nature of a SEE means that it is typically very tightly coupled with the way an organization does business. To be most effective, the components of a SEE must be well integrated and the SEE itself must be integrated with the organization. The challenge of tool integration increases considerably when the components of the environment come from different vendors and support varying degrees of “openness”. The challenge of integration with the organization increases in a like manner when the environment must support a variety of different organizations over a long period of time. In addition to these pressures, any SEE must perform well and must “scale” well as the size of the organization changes. This paper proposes basing the Software Engineering Environment on the software development process used in an organization in order to meet the challenges of integration, performance, and scaling. The goals and services of distributed operating systems and Software Engineering Environments are outlined in order to more clearly define their roles. The motivation for using a well defined software development process is established along with the benefits of basing the Software Engineering Environment on the software development process. Components of a SEE that could effectively support the process and provide integration, performance, and scaling benefits are introduced along with an outline of an Ada program used to model the proposed components. The conclusion provides strong support for process driven SEEs, encourages the expansion of the concept into other “environments,” and cautions against literal interpretations of “process integration” that may slow the acceptance of this powerful approach

Logic-Based Specification Languages for Intelligent Software Agents

The research field of Agent-Oriented Software Engineering (AOSE) aims to find abstractions, languages, methodologies and toolkits for modeling, verifying, validating and prototyping complex applications conceptualized as Multiagent Systems (MASs). A very lively research sub-field studies how formal methods can be used for AOSE. This paper presents a detailed survey of six logic-based executable agent specification languages that have been chosen for their potential to be integrated in our ARPEGGIO project, an open framework for specifying and prototyping a MAS. The six languages are ConGoLog, Agent-0, the IMPACT agent programming language, DyLog, Concurrent METATEM and Ehhf. For each executable language, the logic foundations are described and an example of use is shown. A comparison of the six languages and a survey of similar approaches complete the paper, together with considerations of the advantages of using logic-based languages in MAS modeling and prototyping.Comment: 67 pages, 1 table, 1 figure.

A method for securing online community service: A study of selected Western Australian councils

Since the Internet was made publicly accessible, it has become increasingly popular and its deployment has been broad and global thereby facilitating a range of available online services such as Electronic Mail (email), news or bulletins, Internet Relay Chat (IRC) and World Wide Web (WWW). Progressively, other online services such as telephony, video conference, video on demand, Interactive Television (ITV) and Geographic Information System (GIS) have been integrated with the Internet and become publicly available. Presently, Internet broadband communication services incorporating both wired and wireless network technologies has seen the emergence of the concept of a digital community which has been growing and expanding rapidly around the world. Internet and the ever expanding online services to the wider digital community has raised the issue of security of these services during usage. Most local councils throughout Western Australia have resorted to delivering online services such as library, online payments and email accessibility. The provision and usage of these services have inherent security risks. Consequently, this study investigated the concept of a secure digital community in the secure provision and usage of these online services in selected local councils in Western Australia (WA). After an extensive review of existing literature, information security frameworks were derived from the adaptation of various resources, such as the OSSTMM 2.2 Section C: Internet Technology Security benchmark which was used as the main template. In addition, this template was enhanced into a framework model by incorporating other benchmarks such as NIST, CIS, ISSAF as well as other sources of information. These included information security related books, related ICT network and security websites such as CERT, CheckPoint, Cisco, GFI, Juniper, MS, NESSUS and NMAP together with journals and personal interviews. The proposed information security frameworks were developed to enhance the level of security strength of the email and online web systems as well as to increase the level of confidence in the system security within the selected local councils in WA. All the investigative studies were based upon the available selected local councils’ data and the associated analyses of the results as obtained from the testing software. In addition, the interpretive multiple-case study principles were used during the investigation to achieve or fulfil the purpose of this study. The findings from this study were then abstracted for use in a framework and made available for use as a model for possible adaptation and implementation to other similarly structured councils or organisations. As a result, the study confirmed that the proposed information security frameworks have the capability and potential to improve the level of security strength. In addition, the level of satisfaction and confidence of council staff of the selected local councils in WA in the system security would also be increased due to the application of these frameworks. Although these information security frameworks may be recommended as practical and supporting tools for local councils, the findings from this study were specific only to the selected local councils used in this study. Further research using other councils, may be necessary in order for the information security frameworks to be adopted within a wider range of councils or organisations in WA or elsewhere

User-centred design of a digital advisory service: enhancing public agricultural extension for sustainable intensification in Tanzania

Sustainable intensification (SI) is promoted as a rural development paradigm for sub-Saharan Africa. Achieving SI requires smallholder farmers to have access to information that is context-specific, increases their decision-making capacities, and adapts to changing environments. Current extension services often struggle to address these needs. New mobile phone-based services can help. In order to enhance the public extension service in Tanzania, we created a digital service that addresses smallholder farmers’ different information needs for implementing SI. Using a co-design methodology – User-Centered Design – we elicited feedback from farmers and extension agents in Tanzania to create a new digital information service, called Ushauri. This automated hotline gives farmers access to a set of pre-recorded messages. Additionally, farmers can ask questions in a mailbox. Extension agents then listen to these questions through an online platform, where they record and send replies via automated push-calls. A test with 97 farmers in Tanzania showed that farmers actively engaged with the service to access agricultural advice. Extension agents were able to answer questions with reduced workload compared to conventional communication channels. This study illustrates how User-Centered Design can be used to develop information services for complex and resource-restricted smallholder farming contexts
