Multicriteria Decision Making Using Double Refined Indeterminacy Neutrosophic Cross Entropy And Indeterminacy Based Cross Entropy, Ilanthenral Kandasamy, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

Double Refined Indeterminacy Neutrosophic Set (DRINS) is an inclusive case of the refined neutrosophic set, defined by Smarandache [1], which provides the additional possibility to represent with sensitivity and accuracy the uncertain, imprecise, incomplete, and inconsistent information which are available in real world.

More precision is provided in handling indeterminacy; by classifying indeterminacy (I) into two, based on membership; as indeterminacy leaning towards truth membership (IT ) and indeterminacy leaning towards false membership (IF ). This kind of classification of indeterminacy is not feasible with the existing Single Valued Neutrosophic Set (SVNS), but it is a particular case of the …

Hyperuncertain, Superuncertain, And Superhyperuncertain Sets/Logics/Probabilities/Statistics, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

In this paper, we define for the first time the HyperUncertain, SuperUncertain, and SuperHyperUncertain Sets/Logics/Probabilities/Statistics, the classical case (when the appurtenance degree of a generic element belongs to the unit interval [0, 1]), and the non-classical case (when the appurtenance degree of a generic element is outside on the interval [0, 1]; such theories are called Over/Under/Off-Sets/Logics/Probabilities/Statistics). We prove that the Unary SuperHyperFunction is a generalization of all Uncertain Sets/Logics/Probabilities.

Locating Wojnarowicz: Moving Through Library Systems, Structures And Technologies, Emily Drabinski, Alana Kumbier

Library Philosophy and Practice (e-journal)

This paper asks critical questions about the role of classification structures and descriptive systems in generating new knowledge from library and archives collections. Grounded in theories of articulation advanced by Ernesto Laclau and Chantal Mouffe, the authors posit that librarians and archivists might function better as translators across classifying systems, rather than as merely transcribers and builders of the systems themselves. The analysis looks to two collections of materials by and about queer artist and activist David Wojnarowicz to understand the varying ways libraries and archives construct stable articulations around shifting subjects of knowledge.

Information Asymmetry Between Microfinance Banks And Poor Women In Oyo State, Nigeria: A Critical Examination, Adesoji Tayo, Yacob Haliso, Omolara Tayo

Library Philosophy and Practice (e-journal)

Nigeria like any other developing country is facing the problems of poverty, Nigeria’s case is peculiar given the country’s natural endowment in agriculture, mineral resources, crude oil, human capital and friendly climatic conditions. World Bank estimated that over 70 percent of Nigerians are classified as poor, and half of this number lives in absolute poverty. Indeed, part of the experience in rural development in Nigeria has clearly shown that efforts at expanding the economic base of the rural areas almost always fail because of scarcity of and restrictive access to loanable funds.

Influence Of Information Asymmetry On Microfinance Lending To Women In Oyo State, Nigeria: A Critical Examination, Adesoji Tayo, Yacob Haliso, Omolara Tayo

Library Philosophy and Practice (e-journal)

Poverty is perhaps one of the most difficult challenges bedeviling the developing countries of the world today. Statistical evidences show that there has been a surge in poverty since 1960 in Nigeria. The level of poverty between 2004 and 2010, rose from 54.4%, to 69% and by 2011, relative poverty had risen to about 71.5% (National Bureau of Statistics NBS (2012). Poverty alleviation has been a rather herculean venture because the causes of poverty are ubiquitous and the solution to the problem would require a mix of interventions and programmes in an integrated manner. Microfinance was adopted by Nigeria as …

Virtual worlds are three-dimensional, computer-generated worlds in which team collaboration can be facilitated through the use of shared virtual space and mediated using avatars. This article examines the effect of task complexity on team collaboration. A puzzle game in Second Life was used as the collaborative task and task complexity was manipulated by varying the number of pieces in the puzzle. The hypotheses are that task complexity influences team trust, and team trust influences team process satisfaction in virtual team collaboration. The experimental results indicate that task complexity has significant effects on team trust and team process satisfaction, and team …

A Two-Sided Collaborative Transparent Display Supporting Workspace Awareness, Jiannan Li, Saul Greenberg, Ehud Sharlin

Research Collection School Of Computing and Information Systems

Transparent displays naturally support workspace awareness during face-to-face interactions. Viewers see another person’s actions through the display: gestures, gaze, body movements, and what one is manipulating on the display. Yet we can design even better collaborative transparent displays. First, collaborators on either side should be able to directly interact with workspace objects. Second, and more controversially, both sides should be capable of presenting different content. This affords: reversal of images/text in place (so that people on both sides see objects correctly); personal and private territories aligned atop each other; and GUI objects that provide different visuals for feedthrough vs. feedback. …

Stochastic Invariants For Probabilistic Termination, Krishnendu Chatterjee, Petr Novotný, Dorde Zikelic

Research Collection School Of Computing and Information Systems

Termination is one of the basic liveness properties, and we study the termination problem for probabilistic programs with real-valued variables. Previous works focused on the qualitative problem that asks whether an input program terminates with probability 1 (almost-sure termination). A powerful approach for this qualitative problem is the notion of ranking supermartingales with respect to a given set of invariants. The quantitative problem (probabilistic termination) asks for bounds on the termination probability, and this problem has not been addressed yet. A fundamental and conceptual drawback of the existing approaches to address probabilistic termination is that even though the supermartingales consider …

Concept-Based Interactive Search System, Yi-Jie Lu, Phuong Anh Nguyen, Hao Zhang, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

Our successful multimedia event detection system at TREC-VID 2015 showed its strength on handling complex concepts in a query. The system was based on a large number of pre-trained concept detectors for textual-to-visual relation. In this paper, we enhance the system by enabling human-in-the-loop. In order to facilitate a user to quickly find an information need, we incorporate concept screening, video reranking by highlighted concepts, relevance feedback and color sketch to refine a coarse retrieval result. The aim is to eventually come up with a system suitable for both Ad-hoc Video Search and Known-Item Search. In addition, as the increasing …

Cross-Modal Recipe Retrieval: How To Cook This Dish?, Jingjing Chen, Lei Pang, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

In social media users like to share food pictures. One intelligent feature, potentially attractive to amateur chefs, is the recommendation of recipe along with food. Having this feature, unfortunately, is still technically challenging. First, the current technology in food recognition can only scale up to few hundreds of categories, which are yet to be practical for recognizing ten of thousands of food categories. Second, even one food category can have variants of recipes that differ in ingredient composition. Finding the best-match recipe requires knowledge of ingredients, which is a fine-grained recognition problem. In this paper, we consider the problem from …

Rfid Ownership Transfer With Positive Secrecy Capacity Channels, Jorge Munilla, Mike Burmester, Alberto Peinado, Guomin Yang, Willy Susilo

Research Collection School Of Computing and Information Systems

RFID ownership transfer protocols (OTPs) transfer tag ownership rights. Recently, there has been considerable interest in such protocols; however, guaranteeing privacy for symmetric-key settings without trusted third parties (TTPs) is a challenge still unresolved. In this paper, we address this issue and show that it can be solved by using channels with positive secrecy capacity. We implement these channels with noisy tags and provide practical values, thus proving that perfect secrecy is theoretically possible. We then define a communication model that captures spatiotemporal events and describe a first example of symmetric-key based OTP that: (i) is formally secure in the …

Enabling Sustainable Bulk Transfer In Environmentally-Powered Wireless Sensor Networks, Alvin C. Valera, Wee-Seng Soh, Hwee-Pink Tan

Research Collection School Of Computing and Information Systems

We address the problem of transferring bulk data in environmentally-powered wireless sensor networks where duty cycle compliance is critical for their uninterrupted operation. We propose Pump-and-Nap, a packet train forwarding technique that maximizes throughput while simultaneously enforcing compliance to dynamic duty cycle limitations. A node using Pump-and-Nap operates by pumping a train of packets followed by a napping period where the node forgoes any transmission. Pump-and-Nap employs an adaptive controller to periodically compute the optimal capacity, that is, the maximum number of packets a node can receive and transmit in a train, given its duty cycle constraint. The controller uses …

Online Hacker Forum Censorship: Would Banning The Bad Guys Attract Good Guys?, Qiu-Hong Wang, Le-Ting Zhang, Meng-Ke Qiao

Research Collection School Of Computing and Information Systems

To tackle the ubiquitous cybersecurity threats, a few countries have enacted legislation to criminalize the production, distribution and possession of computer misuse tools. Consequently, online hacker forums, which enable the provision and dissemination of malicious cyber-attack techniques among potential hackers or technology-savvy users, are subject to censorship. This project examines the mixed impacts of online hacker forum censorship on users’ contribution to protection discussion through a natural experiment with large-scale content analysis. We find that while the enforcement indeed reduced the discussion on malicious cyber-attacks, the discussion on cybersecurity protection could increase or decrease in different scenarios. The rationale is …

On The Effectiveness Of Code-Reuse-Based Android Application Obfuscation, Xiaoxiao Tang, Yu Liang, Xinjie Ma, Yan Lin, Debin Gao

Research Collection School Of Computing and Information Systems

Attackers use reverse engineering techniques to gain detailed understanding of executable for malicious purposes, such as re-packaging an Android app to inject malicious code or advertising components. To make reverse engineering more difficult, researchers have proposed various code obfuscation techniques to conceal purposes or logic of code segments. One interesting idea of code obfuscation is to apply codereuse techniques (e.g., Return-Oriented Programming) to (re-)distribute essential code segments before they are reconstructed at runtime. Such techniques are well understood on x86 platform, but relatively less explored on Android. In this paper, we present an evaluation on the extent to which code-reuse-based …
