Digital Game Prototyping Using Board Game/Table Top as it’s Mock Up Case Study: Taman Putroe Phang Game Project

Many of the games with the Indonesian culture adaptations has been developed nowadays. Some of them are made for commercial markets and the other still developed as portfolio and also academic purposes. Some games, already had great gameplay and also had some beautifully digitalized artwork. However, in academic level games projects such as communications designs student’s final projects games prototyping, they often show many errors in the process, especially at gameplay and asset’s development. This circumstances happened because they (the students) lack of the knowledge about how to make a good gameplay based on narrations and always concern about how to designing the visual contents than make it have a great game. With the qualitative research methods by analyzing a games’ project called Taman Putroe Phang, a game project which adapting the Aceh’s Kingdom Romance History. Using game development theory and game design theories, this research wants to explain about how the game developed using board game/ tabletop prototyping before go to the digitalized final game design. The research purpose is to give a perspective and helps the beginner game designer to make a success game prototype using the table top mock up at the process, that shown in game’s prototype.

Diffusive Molecular Communication with Nanomachine Mobility

This work presents a performance analysis for diffusive molecular communication with mobile transmit and receive nanomachines. To begin with, the optimal test is obtained for symbol detection at the receiver nanomachine. Subsequently, closed-form expressions are derived for the probabilities of detection and false alarm, probability of error, and capacity considering also aberrations such as multi-source interference, inter-symbol interference, and counting errors. Simulation results are presented to corroborate the theoretical results derived and also, to yield various insights into the performance of the system. Interestingly, it is shown that the performance of the mobile diffusive molecular communication can be significantly enhanced by allocating large fraction of total available molecules for transmission as the slot interval increases.Comment: To be submitted in 52th Annual Conference on Information Sciences and Systems (CISS

Cognitive MIMO-RF/FSO Cooperative Relay Communication with Mobile Nodes and Imperfect Channel State Information

This work analyzes the performance of an underlay cognitive radio based decode-and-forward mixed multiple-input multiple-output (MIMO) radio frequency/free space optical (RF/FSO) cooperative relay system with multiple mobile secondary and primary user nodes. The effect of imperfect channel state information (CSI) arising due to channel estimation error is also considered at the secondary user transmitters (SU-TXs) and relay on the power control and symbol detection processes respectively. A unique aspect of this work is that both fixed and proportional interference power constraints are employed to limit the interference at the primary user receivers (PU-RXs). Analytical results are derived to characterize the exact and asymptotic outage and bit error probabilities of the above system under practical conditions of node mobility and imperfect CSI, together with impairments of the optical channel, such as path loss, atmospheric turbulence, and pointing errors, for orthogonal space-time block coded transmission between each SU-TX and relay. Finally, simulation results are presented to yield various interesting insights into the system performance such as the benefits of a midamble versus preamble for channel estimation.Comment: revision submitted to IEEE Transactions on Cognitive Communications and Networkin

Enabling Trust in Deep Learning Models: A Digital Forensics Case Study

Today, the volume of evidence collected per case is growing exponentially, to address this problem forensics investigators are looking for investigation process with tools built on new technologies like big data, cloud services, and Deep Learning (DL) techniques. Consequently, the accuracy of artifacts found also relies on the performance of techniques used, especially DL models. Recently, \textbf{D}eep \textbf{N}eural \textbf{N}ets (\textbf{DNN}) have achieved state of the art performance in the tasks of classification and recognition. In the context of digital forensics, DNN has been applied to the domains of cybercrime investigation such as child abuse investigations, malware classification, steganalysis and image forensics. However, the robustness of DNN models in the context of digital forensics is never studied before. Hence, in this research, we design and implement a domain-independent Adversary Testing Framework (ATF) to test the security robustness of black-box DNN's. By using ATF, we also methodically test a commercially available DNN service used in forensic investigations and bypass the detection, where published methods fail in control settings.Comment: 6 pages, Presented at 17th IEEE International Conference On Trust, Security And Privacy In Computing And Communications 201

Masses of Third Family Vector-like Quarks and Leptons in Yukawa-Unified E6E_6

In supersymmetric $E_6$ the masses of the third family quarks and charged lepton, $t-b-\tau$, as well as the masses of the vector-like quarks and leptons, $D-\bar{D}$ and $L-\bar{L}$, may arise from the coupling $27_3$ x $27_3$ x $27_H$, where $27_3$ and $27_H$ denote the third family matter and Higgs multiplets respectively. We assume that the SO(10) singlet component in $27_H$ acquires a TeV scale VEV which spontaneously breaks U(1)$_\psi$ and provides masses to the vector-like particles in $27_3$, while the MSSM doublets in $27_H$ provide masses to $t, b$ and $\tau$. Imposing Yukawa coupling unification $h_t=h_b=h_{\tau}=h_D=h_L$ at $M_{GUT}$ and employing the ATLAS and CMS constraints on the $Z'_\psi$ boson mass, we estimate the lower bounds on the third family vector-like particles $D-\bar{D}$ and $L-\bar{L}$ masses to be around 5.85 TeV and 2.9 TeV respectively. These bounds apply in the supersymmetric limit.Comment: 10 pages, 4 figure

False Discovery Rate Based Distributed Detection in the Presence of Byzantines

Recent literature has shown that the control of False Discovery Rate (FDR) for distributed detection in wireless sensor networks (WSNs) can provide substantial improvement in detection performance over conventional design methodologies. In this paper, we further investigate system design issues in FDR based distributed detection. We demonstrate that improved system design may be achieved by employing the Kolmogorov-Smirnov distance metric instead of the deflection coefficient, as originally proposed in Ray&VarshneyAES11. We also analyze the performance of FDR based distributed detection in the presence of Byzantines. Byzantines are malicious sensors which send falsified information to the Fusion Center (FC) to deteriorate system performance. We provide analytical and simulation results on the global detection probability as a function of the fraction of Byzantines in the network. It is observed that the detection performance degrades considerably when the fraction of Byzantines is large. Hence, we propose an adaptive algorithm at the FC which learns the Byzantines' behavior over time and changes the FDR parameter to overcome the loss in detection performance. Detailed simulation results are provided to demonstrate the robustness of the proposed adaptive algorithm to Byzantine attacks in WSNs.Comment: 28 pages, 9 figures, to appear in IEEE Transactions on Aerospace and Electronic System

Distributed Inference in Tree Networks using Coding Theory

In this paper, we consider the problem of distributed inference in tree based networks. In the framework considered in this paper, distributed nodes make a 1-bit local decision regarding a phenomenon before sending it to the fusion center (FC) via intermediate nodes. We propose the use of coding theory based techniques to solve this distributed inference problem in such structures. Data is progressively compressed as it moves towards the FC. The FC makes the global inference after receiving data from intermediate nodes. Data fusion at nodes as well as at the FC is implemented via error correcting codes. In this context, we analyze the performance for a given code matrix and also design the optimal code matrices at every level of the tree. We address the problems of distributed classification and distributed estimation separately and develop schemes to perform these tasks in tree networks. The proposed schemes are of practical significance due to their simple structure. We study the asymptotic inference performance of our schemes for two different classes of tree networks: fixed height tree networks, and fixed degree tree networks. We show that the proposed schemes are asymptotically optimal under certain conditions.Comment: 16 pages, 7 figures, submitted to IEEE Transactions on Signal Processin

Diffusion Based Cooperative Molecular Communication in Nano-Networks

This work presents a novel diffusion based dual-phase molecular communication system where the source leverages multiple cooperating nanomachines to improve the end-to-end reliability of communication. The Neyman-Pearson Likelihood Ratio Tests are derived for each of the cooperative as well as the destination nanomachines in the presence of multi-user interference. Further, to characterize the performance of the aforementioned system, closed form expressions are derived for the probabilities of detection, false alarm at the individual cooperative, destination nanomachines, as well as the overall end-to-end probability of error. Simulation results demonstrate a significant improvement in the end-to-end performance of the proposed cooperative framework in comparison to multiple-input single-output and single-input single-output molecular communication scenarios in the existing literature.Comment: Revised IEEE WCL Draft (in review process

Passive scalar mixing and decay at finite correlation times in the Batchelor regime

An elegant model for passive scalar mixing was given by Kraichnan assuming the velocity to be delta-correlated in time. We generalize this model to include the effects of a finite correlation time, $\tau$, using renewing flows. The resulting equation for the 3-D passive scalar spectrum $\hat{M}(k,t)$ or its correlation function $M(r,t)$, gives the Kraichnan equation when $\tau \to 0$, and extends it to the next order in $\tau$. It involves third and fourth order derivatives of $M$ or $\hat{M}$ (in the high $k$ limit). For small-$\tau$, it can be recast using the Landau-Lifshitz approach, to one with at most second derivatives of $\hat{M}$. We present both a scaling solution to this equation neglecting diffusion and a more exact solution including diffusive effects. We show that the steady state 1-D passive scalar spectrum, preserves the Batchelor form, $E_\theta(k) \propto k^{-1}$, in the viscous-convective limit, independent of $\tau$. This result can also be obtained in a general manner using Lagrangian methods. Interestingly, in the absence of sources, when passive scalar fluctuations decay, we show that the spectrum in the Batchelor regime and at late times, is of the form $E_\theta(k) \propto k^{1/2}$ and also independent of $\tau$. More generally, finite $\tau$ does not qualitatively change the shape of the spectrum during decay, although the decay rate is reduced. From high resolution ($1024^3$) direct numerical simulations of passive scalar mixing and decay, We find reasonable agreement with predictions of the Batchelor spectrum, during steady state. The scalar spectrum during decay agrees qualitatively with analytic predictions when power is dominantly in wavenumbers corresponding to the Batchelor regime, but is however shallower when box scale fluctuations dominate during decay (abridged).Comment: 32 pages, 7 figures, Journal Of Fluid Mechanics (In Press

Design and Performance Analysis of Dual and Multi-hop Diffusive Molecular Communication Systems

This work presents a comprehensive performance analysis of diffusion based direct, dual-hop, and multi-hop molecular communication systems with Brownian motion and drift in the presence of various distortions such as inter-symbol interference (ISI), multi-source interference (MSI), and counting errors. Optimal decision rules are derived employing the likelihood ratio tests (LRTs) for symbol detection at each of the cooperative as well as the destination nanomachines. Further, closed-form expressions are also derived for the probabilities of detection, false alarm at the individual cooperative, destination nanomachines, as well as the overall end-to-end probability of error for source-destination communication. The results also characterize the impact of detection performance of the intermediate cooperative nanomachine(s) on the end-to-end performance of dual/multi hop diffusive molecular communication systems. In addition, capacity expressions are also derived for direct, dual-hop, and multi-hop molecular communication scenarios. Simulation results are presented to corroborate the theoretical results derived and also, to yield insights into system performance.Comment: in preparatio
