DYSWIS: Collaborative Network Fault Diagnosis - Of End-users, By End-users, For End-users

With increase in application complexity, the need for network faults diagnosis for end-users has increased. However, existing failure diagnosis techniques fail to assist the endusers in accessing the applications and services. We present DYSWIS, an automatic network fault detection and diagnosis system for end-users. The key idea is collaboration of end-users; a node requests multiple nodes to diagnose a network fault in real time to collect diverse information from different parts of the networks and infer the cause of failure. DYSWIS leverages DHT network to search the collaborating nodes with appropriate network properties required to diagnose a failure. The framework allows dynamic updating of rules and probes into a running system. Another key aspect is contribution of expert knowledge (rules and probes) by application developers, vendors and network administrators; thereby enabling crowdsourcing of diagnosis strategy for growing set of applications. We have implemented the framework and the software and tested them using our test bed and PlanetLab to show that several complex commonly occurring failures can be detected and diagnosed successfully using DYSWIS, while single-user probe with traditional tools fails to pinpoint the cause of such failures. We validate that our base modules and rules are sufficient to detect infrastructural failures causing majority of application failures

Bridging End Users' Terms and AGROVOC Concept Server Vocabularies

The AGROVOC is a multilingual structured thesaurus in the agricultural domain. It has already been mapped with several vocabularies, for example AGROVOC-CAT, AGROVOC-NALT , AGROVOC-SWD. Although these vocabularies already contained a good portion of non-preferred terms, the terms are collected under the literary warrant and institutional warrant principles; which means vocabularies were collected based on the documents and publications rather than user‟s queries. It is still very common that end users would use different terms to express the same concept. In light of above discussion, we need to bridge these vocabularies and the users‟ terms Backgroun

Modeling Security Policy and the Effect for End-Users

Many "good practices" in computer security are based on assumptions and local evidence that do not generalize. There are few quantifiable methods of establishing or refuting the validity of these practices from a user perspective. We propose a formal model of security policies that allows us to evaluate the claimed benefits to the user of the system quantitatively. We illustrate the use of the model by looking at a security policy we all live with daily: The Password Policy

Systems for End Users: Are There End Users for the Systems?

Focuses on the sixth national meeting on online information search systems held in the Spring of 1985 in New York. User-friendly substitutes for system manuals and documentation; Proliferation of online hosts; Introduction of menu option for assessment of system

CAN END-USERS PROGRAM?

In recent years, personal computing has changed direction and is now more inclined towards the world of mobile computing. This means that end-users expect a simpler and more personalized experience. To achieve the highest level of customization, end-users must develop their own applications. However, end-users usually lack in having the right skills for that task. To address this problem, many end-users programming languages and frameworks have been devised. These are particularly aimed at reducing syntax and cognitive gaps. However, some of the existing solutions reduced the expressiveness of the language and thus reduced the generality of the program, while others remains too complex for end-users. In this work we devise a new framework, named Dev4Me, designed from the ground up to provide end-users a solution for developing mobile and personal apps. The framework is made up of a new form-based language, an Integrated Development Environment (IDE) and an execution environment. The new framework enables the users to develop, test, debug and use their own apps in a few simple steps, using familiar form filling experience

PENGARUH KETIDAKPASTIAN TUGAS TERHADAP HUBUNGAN ANTARA KEANEKARAGAMAN DAN TINGKAT PEMANFAATAN TEKNOLOGI DENGAN KEPUASAN PEMAKAI

The aim of this research is to test the influence of diversity andthe extent ofutilization of information technology on the end-users computing satisfaction. This research is also to test the interaction ffict between two dimensions of task uncertainty, which are task variability and analyzability with the two dimensions of utilization of information technology on the end-users computing satisfaction. The samples and respondents from this research are employees of bankingfirms who use computer and a number business applications. This research used survey method with 73 samples. Analysis method used in this research is multiple regression to examine correlation between dimension of utilization with end-users computing satisfaction, and relationship between the two dimension ffict two dimensions of utilization and two dimension of task uncertainty on the end-users computing is used moderated regression analysis (MRA). The result shows that diversity and the extent of utilizationhave apositive influence onthe end-users computing satisfaction. While, the diversityof utilization have a positive relationship with task vatiability, and then the extent of utilization have a negative relationship with task analyzability. And the test of interaction ffict between two dimensions of utilitzation and two dimenstons of task uncertainty have not significantly influence on the end-users satisfaction

Scientists in the MIST: Simplifying Interface Design for End Users

We are building a Malleable Interactive Software Toolkit (MIST), a tool set and infrastructure to simplify the design and construction of dynamically-reconfigurable (malleable) interactive software. Malleable software offers the end-user powerful tools to reshape their interactive environment on the fly. We aim to make the construction of such software straightforward, and to make reconfiguration of the resulting systems approachable and manageable to an educated, but non-specialist, user. To do so, we draw on a diverse body of existing research on alternative approaches to user interface (UI) and interactive software construction, including declarative UI languages, constraint-based programming and UI management, reflection and data-driven programming, and visual programming techniques
