Purpose – The underlying objective of this literature review was to investigate what kinds of semiotics researches have been employed in user interfaces design and usability evaluation, and how were they employed.Design/methodology/approach – This research follows a systematic literature review process that consists of three key stages: planning the review, conducting the review, and reporting the review. Starting with an initial set of about 1,000 research articles, 65 were selected for this review, using an inclusion and exclusion criteria. Qualitative and quantitative data were extracted from the selected literatures following a data extraction strategy in six themes of data extraction. The extracted data were synthesized to formulate the stated research questions to obtain the review goals.Findings – This systematic review identified research strengths, gaps, and challenges. Apart from this, further research possibilities were also explored in this review. For research, the review showed clear needs f...

A systematic literature review of semiotics perception in user interfaces

Due to the low cost of easy-to-use components of open-source hardware and software, the Internet of Things may be pervading through everything everywhere. The dependability of the Internet of Things is critical because the services will be concerned with real life. However, the inexpensive hardware provides limited resources for communication. In this paper, we present exact all-terminal reliability of the wireless networks of which the number of links of each node is bounded. First, we analyze the all-terminal reliability of the regular wireless network, where any two nodes are connected by a wireless link consisting of a pair of radio modules. The reliability polynomial is derived from the Tutte polynomial that is the seminal work of the algebraic graph theory. Second, we analyze the all-terminal reliability of the wireless network including the random mesh network under the assumption that if the module fails, all radio links connected through a radio module are cut off. We consider both the fault of the communication module and the fading of the wireless channel in the indoor channel condition. For improving the reliability, we also propose a fault-tolerant method giving redundant radio modules into each node. We also analyze cost-effectiveness. We also calculate the mean-time-to-failure (MTTF) for wireless networks. We show that the random mesh network of which each node includes three or more the radio-broadcast modules is more dependable than any other regular network of which each node comprises four point-to-point modules if it is the connected graph in the static environment.

All-Terminal Reliability Analysis of Wireless Networks of Redundant Radio Modules

We reviewed papers in core IS outlets that defined the term workaround or presented an example of a workaround. In the analysis, we used Ogden and Richard's triangle of reference as a theoretical f ...

Conceptualizing Workarounds : Meanings and Manifestations in Information Systems Research

This chapter presents an introduction to graph colouring algorithms. The focus is on vertex-colouring algorithms that work for general classes of graphs with worst-case performance guarantees in a sequential model of computation. The presentation aims to demonstrate the breadth of available techniques and is organized by algorithmic paradigm.

Time-dependent reliability of wireless networks with dependent failures

The computation of chromatic polynomials

Graph theory is an integral part of a discrete structures course required in computer science programs. Unfortunately, in the short time such courses devote to graph theory, students often do not appreciate and/or recognize how graph theory notions and theorems become problem modeling and problem solving tools. Graph Works is a visualization tool to show what properties of graph mean in terms of a particular graph and what properties and substructures fundamental theorems guarantee to exist in a graph. The tool is designed to help users understand and develop algorithms that use graph properties needed for problem solving or find and use particular subgraphs as part of the solution process.

Graph works - pilot graph theory visualization tool

The success of information system development projects is critically dependent on arriving at a shared understanding of the desired outcome by all project stakeholders. To communicate such understanding among stakeholders, development artifacts such as design specifications, prototypes, and user stories are created. This paper presents a new project management tool to measure and ensure common understanding of such development artifacts. The method is based on Peirce’s theory of semiotics and Mayer’s theory of learning. The application of the method is demonstrated using a brief example.

Improving Mutual Understanding of Development Artifacts: A Semiotics-Based Approach

The Tutte polynomial of a graph, also known as the partition function of the q-state Potts model, is a 2-variable polynomial graph invariant of considerable importance in both combinatorics and statistical physics. It contains several other polynomial invariants, such as the chromatic polynomial and flow polynomial as partial evaluations, and various numerical invariants such as the number of spanning trees as complete evaluations. We have developed the most efficient algorithm to-date for computing the Tutte polynomial of a graph. An important component of the algorithm affecting efficiency is the choice of edge to work on at each stage in the computation. In this paper, we present and discuss two edge-selection heuristics which (respectively) give good performance on sparse and dense graphs. We also present experimental data comparing these heuristics against a range of others to demonstrate their effectiveness.
