A Quantitative Cost/Benefit Analysis For Dynamic Updating, Bashar Gharaibeh, Hridesh Rajan, J. Morris Chang 2017 Iowa State University

A Quantitative Cost/Benefit Analysis For Dynamic Updating, Bashar Gharaibeh, Hridesh Rajan, J. Morris Chang

Morris Chang

Dynamic software updating provides many benefits, e.g. in runtime monitoring, runtime adaptation to fix bugs in long running applications, etc. Although it has several advantages, no quantitative analysis of its costs and revenue are available to show its benefits or limitations especially in comparison with other software updating schemes. To address this limitation in evaluating software updating schemes, we contribute a quantitative cost/benefit analysis based on net option-value model, which stems from the analysis of financial options. Our model expresses the relation between added value and paid cost in mathematical forms. We have used this model to evaluate ...

Neural Networks For Real-Time Pathfinding In Computer Games, Ross Graham, Hugh McCabe, Stephen Sheridan 2017 School oflnformatics and Engineering, Institute of Technology at Blanchardstown, Dublin l5.

Neural Networks For Real-Time Pathfinding In Computer Games, Ross Graham, Hugh Mccabe, Stephen Sheridan

The ITB Journal

One of the greatest challenges in the design of realistic Artificial Intelligence (Al) in computer games is agent movement. Pathfinding strategies are usually employed as the core of any AI movement system. The two main components for basic real-time pathfinding are (i) travelling towards a specified goal and (ii) avoiding dynamic and static obstacles that may litter the path to this goal. The focus of this paper is how machine learning techniques, such as Artificial Neural Networks and Genetic Algorithms, can be used to enhance an AI agent's ability to handle pathfinding in real-time by giving them an awareness ...


Emotion Authentication: A Method For Voice Integrity Checking, C. Reynolds, L. Vasiu, M. Smith 2017 Middlesex University, School of Computing science, Bramley Rd, Oakwood, N14 4YZ UK.

Emotion Authentication: A Method For Voice Integrity Checking, C. Reynolds, L. Vasiu, M. Smith

The ITB Journal

When people communicate with telephone type systems, it is often assumed that the listener would notice any modification of the speaker's voice. It is possible however to introduce small changes that would not be noticed by a listener but could modify the reading of a Voice Stress Analyser, popularly referred to as a lie detector. Existing approaches to checking the integrity of voice require significant amounts of processing or are able to detect only non-subtle modification such as change of speaker. With the advent of real time voice modification using software and hardware based signal processing, we argue that ...

Strengthening The Practices Of An Agile Methodology?, Jimmy Doody, Amanda O'Farrell

The ITB Journal

An investigation into how the software development process in an agile environment (Extreme Programming) can be aided by intelligent software, leading to the development of a tool that will automate the process of standardising and clarifying source code. The tool will also speed up and aid the testing process, by producing test objects based on the source code, and by providing full test tracking, without having a negative impact on the development process. By making the coding and testing processes more automated, the research aims to evaluate the following hypotheses: 1. That the programmer's productivity can be increased by ...

An Open Source Discussion Group Recommendation System, Sarika Padmashali 2017 San Jose State University

An Open Source Discussion Group Recommendation System, Sarika Padmashali

Master's Projects

A recommendation system analyzes user behavior on a website to make suggestions about what a user should do in the future on the website. It basically tries to predict the “rating” or “preference” a user would have for an action. Yioop is an open source search engine, wiki system, and user discussion group system managed by Dr. Christopher Pollett at SJSU. In this project, we have developed a recommendation system for Yioop where users are given suggestions about the threads and groups they could join based on their user history. We have used collaborative filtering techniques to make recommendations and ...


Web - Based Office Market, Manodivya Kathiravan 2017 San Jose State University

Web - Based Office Market, Manodivya Kathiravan

Master's Projects

People who work in an office often have different pools of resources that they want to exchange. They want to trade their resources/work(seller) with a person who wants that particular resource(buyer) and in return get another resource the buyer offers. These kind of exchanges are often called Barter-exchanges where an item is traded for another item without the involvement of actual money. An exchange is set to be complete when there is a match between an available item and a desired item. This exchange is called direct exchange. When an item desired by one user is made ...


Automated Refactoring Of Legacy Java Software To Default Methods, Raffi T. Khatchadourian, Hidehiko Masuhara 2017 CUNY Hunter College

Automated Refactoring Of Legacy Java Software To Default Methods, Raffi T. Khatchadourian, Hidehiko Masuhara

Publications and Research

Java 8 default methods, which allow interfaces to contain (instance) method implementations, are useful for the skeletal implementation software design pattern. However, it is not easy to transform existing software to exploit default methods as it requires analyzing complex type hierarchies, resolving multiple implementation inheritance issues, reconciling differences between class and interface methods, and analyzing tie-breakers (dispatch precedence) with overriding class methods to preserve type-correctness and confirm semantics preservation. In this paper, we present an efficient, fully-automated, type constraint-based refactoring approach that assists developers in taking advantage of enhanced interfaces for their legacy Java software. The approach features an extensive ...


Library For Writing Contracts For Java Programs Using Prolog, Yogesh Dixit 2017 San Jose State University

Library For Writing Contracts For Java Programs Using Prolog, Yogesh Dixit

Master's Projects

Today many large and complex software systems are being developed in Java. Although, software always has bugs, it is very important that these developed systems are more reliable despite these bugs.

One way that we can help achieve this is the Design by Contract (DbC) paradigm, which was first introduced by Bertrand Meyer, the creator of Eiffel. The concept of DbC was introduced for software developers so that they can produce more reliable software systems with a little extra cost. Using programming contracts allows developer to specify details such as input conditions and expected output conditions. Doing this makes it ...

Over the past few years, messaging applications have become more popular than Social networking sites. Instead of using a specific application or website to access some service, chatbots are created on messaging platforms to allow users to interact with companies’ products and also give assistance as needed. In this project, we designed and implemented a chatbot Framework for Yioop. The goal of the Chatbot Framework for Yioop project is to provide a platform for developers in Yioop to build and deploy chatbot applications. A chatbot is a web service that can converse with users using artificial intelligence in messaging platforms ...


A Ltihub For Composite Assignments, Sunita Rajain 2017 San Jose State University

A Ltihub For Composite Assignments, Sunita Rajain

Master's Projects

Learning management systems (LMS) such as Canvas and Blackboard use Learning Tool Interoperability (LTI) as their main integration point for external learning tools. Each external tool provider has to implement LTI specifications or follow LTI standards that is a time consuming and complex process as there is no easy to follow specification available. Through this project, I have developed a system that follows the LTI specifications and integrates the CodeCheck autograder and interactive exercises with any LMS. I developed a Java based web app named LTIHub that acts as a mediator between LMS and any Learning Tool Provider. The LTIHub ...


Automated Refactoring Of Legacy Java Software To Default Methods, Raffi T. Khatchadourian, Hidehiko Masuhara 2017 CUNY Hunter College

Automated Refactoring Of Legacy Java Software To Default Methods, Raffi T. Khatchadourian, Hidehiko Masuhara

Publications and Research

Java 8 introduces enhanced interfaces, allowing for default (instance) methods that implementers will inherit if none are provided [3]. Default methods can be used [2] as a replacement of the skeletal implementation pattern [1], which creates abstract skeletal implementation classes that implementers extend. Migrating legacy code using the skeletal implementation pattern to instead use default methods can require significant manual effort due to subtle language and semantic restrictions. It requires preserving typecorrectness by analyzing complex type hierarchies, resolving issues arising from multiple inheritance, reconciling differences between class and interface methods, and ensuring tie-breakers with overriding class methods do not alter ...

Music Feature Matching Using Computer Vision Algorithms, Mason Hollis 2017 University of Arkansas, Fayetteville

Music Feature Matching Using Computer Vision Algorithms, Mason Hollis

Computer Science and Computer Engineering Undergraduate Honors Theses

This paper seeks to establish the validity and potential benefits of using existing computer vision techniques on audio samples rather than traditional images in order to consistently and accurately identify a song of origin from a short audio clip of potentially noisy sound. To do this, the audio sample is first converted to a spectrogram image, which is used to generate SURF features. These features are compared against a database of features, which have been previously generated in a similar fashion, in order to find the best match. This algorithm has been implemented in a system that can run as ...

A Data-Driven Approach For Benchmarking Energy Efficiency Of Warehouse Buildings, Wee Leong Lee, Kar Way Tan, Zui Young Lim

Research Collection School Of Information Systems

This study proposes adata-driven approach for benchmarking energy efficiency of warehouse buildings.Our proposed approach provides an alternative to the limitation of existingbenchmarking approaches where a theoretical energy-efficient warehouse was usedas a reference. Our approach starts by defining the questions needed to capturethe characteristics of warehouses relating to energy consumption. Using an existingdata set of warehouse building containing various attributes, we first cluster theminto groups by their characteristics. The warehouses characteristics derivedfrom the cluster assignments along with their past annual energy consumptionare subsequently used to train a decision tree model. The decision tree providesa classification of what factors contribute to ...


A Hybrid Partially Reconfigurable Overlay Supporting Just-In-Time Assembly Of Custom Accelerators On Fpgas, Zeyad Tariq Aklah 2017 University of Arkansas, Fayetteville

A Hybrid Partially Reconfigurable Overlay Supporting Just-In-Time Assembly Of Custom Accelerators On Fpgas, Zeyad Tariq Aklah

Theses and Dissertations

The state of the art in design and development flows for FPGAs are not sufficiently mature to allow programmers to implement their applications through traditional software development flows. The stipulation of synthesis as well as the requirement of background knowledge on the FPGAs' low-level physical hardware structure are major challenges that prevent programmers from using FPGAs. The reconfigurable computing community is seeking solutions to raise the level of design abstraction at which programmers must operate, and move the synthesis process out of the programmers' path through the use of overlays. A recent approach, Just-In-Time Assembly (JITA), was proposed that enables ...


Towards Automatic Repair Of Xacml Policies, Shuai Peng 2017 Boise State University

Towards Automatic Repair Of Xacml Policies, Shuai Peng

Boise State University Theses and Dissertations

In a complex information system, controlling the access to resources is challenging. As a new generation of access control techniques, Attribute-Based Access Control (ABAC) can provide more flexible and fine-grained access control than Role-Based-Access Control (RBAC). XACML (eXtensible Access Control Markup Language) is an industrial standard for specifying ABAC policies. XACML policies tend to be complex because of the great variety of attribute types for fine-grained access control. This means that XACML policies are prone to errors and difficult to debug. This paper presents a first attempt at automating the debugging process of XACML policies. Two techniques are used for ...
