In many cases poor information quality appears mainly due to in-effectiveness of information management including information production and delivery. Where this situation poses a certain risk. A holistic information risk management model... more
Open source software (OSS) in academia can have multiple types of implementations and positive returns. This paper explores the use of OSS as a method to teach entrepreneurship concepts and practices to Science, Technology, Engineering,... more
Motivated by some recent research on the terminal (reduced) distance matrix, we consider the terminal Wiener index (T W ) of trees, equal to the sum of distances between all pairs of pendent vertices. A simple formula for computing T W is... more
Until now, Augmented Reality was mainly associated with visual augmentation which was often reduced to superimposing a virtual object on to a real world. We present in this document a vibro-tactile system called HaptiNav, which... more
A Computational Study of Redundancy in Randomly Generated Polytopes. In this paper we first survey a number of principles used to randomly generate linear programming problems. Three major classes of LP generators are identified and :on... more
We survey and extend the work on the paradigm called "computing by observing". Its central feature is that one considers the behavior of an evolving system as the result of a computation. To this purpose an external observer records this... more
The mapping algorithms address the problem of acquiring spatial models of physical environments using mobile robots. We will focus on using the indoor exploration algorithms to construct a map for such environment. Therefore, the problem... more
El presente artículo pretende brindar luces acerca de la importancia de la Psicología Organizacional en el ámbito laboral y ayudarnos a comprender cómo ésta puede resolver conflictos en la organización complementándose con diferentes... more
An Internet of Things (IoT) middleware can solve interoperability problem among "things" in IoT infrastructure by collecting data. However, the sensor nodes' data that is collected by the middleware cannot be directly delivered to cloud... more
Automation of several payment processes from start to end is a challenging task, particularly when multiple payments from online and offline billers are involved. In this paper, we introduced a new aggregator system to combine all billing... more
Recently, both companion-matrix methods and subdivision algorithms have been developed for finding the zeros of a truncated spectral series. Since the Chebyshev or Legendre coefficients of derivatives of a function f (x) can be computed... more
This paper proposes Cognitive Artificial Intelligence (CAI) method for Dissolved Gas Analysis (DGA) interpretation adopting Doernenburg Ratio method. CAI works based on Knowledge Growing System (KGS) principle and is capable of growing... more
Computers have a direct impact on our lives nowadays. Human's interaction with the computer has modified with the passage of time as improvement in technology occurred the better the human computer interaction became. Today we are... more
Document Standard Operating Procedures (SOP) can manage business processes and employee performance in an organization. This study aims to develop a system that can publish SOP documents automatically distributed to employees. In this... more
Load balancing functionalities are crucial for best Grid performance and utilization. Accordingly,this paper presents a new meta-scheduling method called TunSys. It is inspired from the natural phenomenon of heat propagation and thermal... more
Imaging spectrometry, or hyperspectral imaging as it is now called, has had a long history of development and measured acceptance by the scientific community. The impetus for the development of imaging spectrometry came in the 1970's from... more
In this paper, we consider smooth words over 2-letter alphabets {a, b}, where a, b are integers having same parity, with 0 < a < b. We show that all are recurrent and that the closure of the set of factors under reversal holds for odd... more
The concept of the Internet of Things (IoT) is closely related to the concepts of Cyber-Physical System (CPS) and Cyber-Physical-Social System (CPSS). A key feature of these technologies is the integration of the virtual and physical... more
Interpolants for Runge-Kutta-Nystriim Methods. Hermite interpolation polynomials arc developed for use with low order Runge-Kutta-Nystr6m methods in producing continuous approximate solutions to second order initial value problems,... more
Both Governments and people around the world have started appreciating the ability of Information and Communications Technology (ICT) to stimulate critical sectors of the economy. These technological innovations provide speedy,... more
Performance is a key feature of large-scale computing systems. However, the achieved performance when a certain program is executed is significantly lower than the maximal theoretical performance of the large-scale computing system. The... more
One of the main causes of traffic congestion, especially at intersections, is because traffic lights have not been able to show the right time according to the existing traffic conditions. Time settings based on peak/off-peak traffic... more
In mission critical systems a single failure might cause catastrophic consequences. This sets high expectations to timely detection of design faults and runtime failures. By traditional software testing methods the detection of deeply... more
The aim of study is to discover outlier of customer data to found customer behaviour. The customer behaviour determined with RFM (Recency, Frequency and Monetary) models with K-Mean and DBSCAN algorithm as clustering customer data. There... more
The problem of predicting a future value of a time series is considered in this paper. If the series follows a stationary Markov process, this can be done by nonparametric estimation of the autoregression function. Two forecasting... more
One of the most significant innovation in the Information Technology (IT) industry after the introduction of the personal computer and the internet is Cloud computing. The shift to cloud is a landmark in the IT industry and has raised... more
8th International Conference on Computational Science and Engineering (CSE 2020) focuses on Complex systems, information and computation using mathematics and engineering techniques. This conference will act as a major forum for the... more
This work is dedicated to the memory of Prof. Germund Dahlquist.
This research explores the accessibility issues with regard to the e-commerce websites in developing countries, through a study of Sri Lankan hotel websites. A web survey and a web content analysis were conducted as the methods to elicit... more
One of the main challenges students in introductory programming courses face is learning the syntax of a particular programming language, such as C++ or Java, while they simultaneously try to understand the fundamental logic of... more
Efficient Classes of Runge-Kutta Methods for Two-Point Boundary Value Problems. The standard approach to applying IRK methods in the solution of two-point boundary value problems involves the solution of a non-linear system ofn x s... more
Meaning is the essence. It is the primary reason for us to keep doing things. Meaning is both significance and the endless unfolding of significance. Visual Meaning is fundamental for visual arts and design processes. One draws, paints,... more
Mathematics is the abstract science of number, quantity, and space, either as abstract concepts (pure mathematics), or as applied to other disciplines such as physics and engineering (applied mathematics). Computing, finance, business,... more
The study aims to assess the students' continuance intention (SCI) in using multimedia online learning including students' perceived usefulness (SPU), students' ease of use (SPE), and students' flow experience (SFE). There is no, so far,... more
