Evaluating Planning-Based Experience Managers for Agency and Fun in Text-Based Interactive Narrative

Artificial intelligence (AI) techniques have been applied to video games to make the overall experience more enjoyable. In games with interactive storytelling (IS), player actions can substantially affect plot events and plot characters. Therefore, AI planning techniques have been used to shape the plot inresponse to player actions that conflict with authorial goals. While such methods are poised to increase player fun andagency, two recent implementations (ASD and PAST) have not been formally evaluated to date. In this paper we do so via a series of user studies for the first time. We show that ASD significantly enhances fun and agency, whereas PAST gets mixed results with an interaction between effects of the experience manager and player prior gaming experience in one user study, and marginally significant results for increased agency in a study with a constrained story domain.
Visualization Tool for Collective Awareness in a Platform of Citizen Proposals

Online debate tools for participatory democracy and crowdsourcing legislation are limited by different factors. One of them arises when discussion of proposals reaches a large number of contributions and therefore citizens encounter difficulties in mapping the arguments that constitute the dialectical debate. To address this issue, we present a visualization tool that shows the discussion of any proposal as an interactive radial tree. The tool builds on Decide Madrid, a recently created platform for direct democracy launched by the City Council of Madrid. Decide Madrid is one of the most relevant platforms that allows citizens to propose, debate and prioritise city policies.
Biomedical Term Extraction: NLP Techniques in Computational Medicine

Artificial Intelligence (AI) and its branch Natural Language Processing (NLP) in particular are main contributorsto recent advances in classifying documentation and extracting information from assorted fields, Medicinebeing one that has gathered a lot of attention due to the amount of information generated in public professionaljournals and other means of communication within the medical profession. The typical information extractiontask from technical texts is performed via an automatic term recognition extractor. Automatic Term Recognition(ATR) from technical texts is applied for the identification of key concepts for information retrieval and,secondarily, for machine translation. Term recognition depends on the subject domain and the lexical patternsof a given language, in our case, Spanish, Arabic and Japanese. In this article, we present the methods andtechniques for creating a biomedical corpus of validated terms, with several tools for optimal exploitation ofthe information therewith contained in said corpus. This paper also shows how these techniques and tools havebeen used in a prototype.
What Does Augmented Reality Mean as a Medium of Expression for Computational Artists?

As augmented reality (AR) quickly evolves with new technological practice, there is a growing need to question and reevaluate its potential as a medium for creative expression. The authors discuss AR within computational art, framed within AR as a medium, AR aesthetics and applications. The Forum for Augmented Reality Immersive Instruments (ARImI), a two-day event on AR, highlights both possibilities and fundamental concerns for continuing artworks in this field, including visual bias, sensory modalities, interactivity and performativity. The authors offer a new AR definition as real-time computationally mediated perception.
The Development of Teaching Material Based on Multiple Intelligence Theory of Central Learning Model for Childhood Aged 5-6 Years

This study aims to develop teaching materials based on the multiple intelligences theory in central learning models for childhood aged 5-6 years, in the form of teacher manuals and student worksheets. This study uses a development model of ADDIE (Analysis, Design, Development, Implementation, Evaluation) which contains needs analysis and curriculum analysis to test the effectiveness of instructional materials. The results of the validation of teaching material books were analysed using descriptive presentations. Field trials of teaching material books were conducted on 22 students as research subjects. The results of the development of teaching material books based on the multiple intelligences theory of content / material experts scored 82%, from learning media experts scored 95% and from peers obtained a score of 94%. The use of teaching material books in learning gets good responses from principals and teachers based on the interview results stating that the use of teaching materials based on the multiple intelligences theory in the central learning model makes students become creative and active so learning becomes fun. Whereas from the observation results, the scale of students 'developmental achievements shows students' development in accordance with the expectations and activeness of the students very well. The results of the research obtained can be concluded that the development of teaching materials in the form of teacher manuals and student worksheets based on the multiple intelligences theory in the centre of learning model aged 5-6 years is valid and suitable for use in classroom learning.
A Maximum Likelihood Approach for Depth Field Estimation Based on Epipolar Plane Images

In this paper, a multi-resolution method for depth estimation from dense image arrays is presented. Recent progress in consumer electronics has enabled the development of low cost hand-held plenoptic cameras. In these systems, multiple views of a scene are captured in a single shot by means of a micro-lens array placed on the focal point of the first camera lens, in front of the imaging sensor. These views can be processed jointly to obtain accurate depth maps. In this contribution, to reduce the computational complexity associated to global optimization schemes based on match cost functions, we make a local estimate based on the maximization of the total log-likelihood spatial density aggregated along the epipolar lines corresponding to each view pair. This method includes the local maximum likelihood estimation of the depth field based on epipolar plane images. To face the potential accuracy losses associated to the ambiguity problem that arises in flat surface regions while preserving bandwidth in correspondence of the edges, we adopt a multi-resolution scheme. In practice, the depth map resolution is reduced in regions where maximizing the higher resolution functional is ill-conditioned. The main benefits of the proposed system are in a reduced computational complexity and a high accuracy of the estimated depth. Experimental results show that the proposed scheme represents a good tradeoff among accuracy, robustness, and discontinuities handling.
Fréchet distance under translation: conditional hardness and an algorithm via offline dynamic grid reachability

The discrete Frechet distance is a popular measure for comparing polygonal curves. An important variant is the discrete Frechet distance under translation, which enables detection of similar movement patterns in different spatial domains. For polygonal curves of length n in the plane, the fastest known algorithm runs in time O(n5) [Ben Avraham, Kaplan, Sharir '15]. This is achieved by constructing an arrangement of disks of size O(n4), and then traversing its faces while updating reachability in a directed grid graph of size N = O(n2), which can be done in time [MATH HERE] per update [Diks, Sankowski '07]. The contribution of this paper is two-fold.First, although it is an open problem to solve dynamic reachability in directed grid graphs faster than [MATH HERE], we improve this part of the algorithm: We observe that an offline variant of dynamic s−t-reachability in directed grid graphs suffices, and we solve this variant in amortized time O(N1/3) per update, resulting in an improved running time of O(n4.66. . .) for the discrete Frechet distance under translation. Second, we provide evidence that constructing the arrangement of size O(n4) is necessary in the worst case, by proving a conditional lower bound of n4−−o(1) on the running time for the discrete Frechet distance under translation, assuming the Strong Exponential Time Hypothesis.
Visualizing Information Diffusion and Polarization with Key Statements

This paper reports ongoing work in the “Networks of Texts and People” project, which is developing methods to visualize the social and epistemological contexts of information contained in blogs. Here, we propose an approach to visualize information diffusion and polarization in the blogosphere, with two novel characteristics. Firstly, we demonstrate how text content can be analyzed and visualized as key statements, rather than as keywords. Secondly, we sketch and discuss ideas for a visual analytic tool that integrates data about blog networks with data about the occurrence of related key statements in blog posts.

On the Suitability of Fuzzy Rule-Based Classification Systems with Noisy Data

Noise is common in any real-world dataset and may adversely affect the accuracy, construction time and complexity of the classifiers. Fuzzy Rule-Based Classification Systems build classifiers widely recognized for their interpretability but also for their good performance and robustness when dealing with imperfect data. This paper analyzes the behavior of such systems with respect to classic crisp systems in the presence of noise. We study the performance of these systems and their robustness in terms of the performance degradation and the size of the classifiers when the noise level increases in training data. We also study their performance when noise is only present in test data the result of a training data polishing and their synergy with several noise filters. The results obtained show that Fuzzy Rule-Based Classification Systems obtain better performance results than crisp systems when they are trained with noisy data. Their robustness results are particularly notable when noise is more disruptive. Their evaluation on noisy test data and their combined use with noise filters are also shown to be appropriate.

Postquantum Preshared Keys for IKEv2

The possibility of Quantum Computers pose a serious challenge tocryptography algorithms deployed widely today. IKEv2 is one example ofa cryptosystem that could be broken; someone storing VPNcommunications today could decrypt them at a later time when a QuantumComputer is available. It is anticipated that IKEv2 will be extendedto support quantum secure key exchange algorithms; however that is notlikely to happen in the near term. To address this problem beforethen, this document describes an extension of IKEv2 to allow it to beresistant to a Quantum Computer, by using preshared keys.
A new approach to kimberlite facies terminology using a revised general approach to the nomenclature of all volcanic rocks and deposits: descriptive to genetic

Although kimberlite pipes/bodies are usually the remains of volcanic vents, in-vent deposits, and subvolcanic intrusions, the terminology used for kimberlite rocks has largely developed independently of that used in mainstream volcanology. Existing kimberlite terminology is not descriptive and includes terms that are rarely used, used differently, and even not used at all in mainstream volcanology. In addition, kimberlite bodies are altered to varying degrees, making application of genetic terminology difficult because original components and depositional textures are commonly masked by alteration. This paper recommends an approach to the terminology for kimberlite rocks that is consistent with usage for other volcanic successions. In modern terrains the eruption and emplacement origins of deposits can often be readily deduced, but this is often not the case for old, variably altered and deformed rock successions. A staged approach is required whereby descriptive terminology is developed first, followed by application of genetic terminology once all features, including the effects of alteration on original texture and depositional features, together with contact relationships and setting, have been evaluated. Because many volcanic successions consist of both primary volcanic deposits as well as volcanic sediments, terminology must account for both possibilities.
Partial Delete Relaxation, Unchained: On Intractable Red-Black Planning and Its Applications

Partial delete relaxation methods, like red-black planning, are extremely powerful, allowing in principle to force relaxed plans to behave like real plans in the limit. Alas, that power has so far been chained down by the computational overhead of the use as heuristic functions, necessitating to compute a relaxed plan on every search state. For red-black planning in particular, this has entailed an exclusive focus on tractable fragments. We herein unleash the power of red-black planning on two applications not necessitating such a restriction: (i) generating seed plans for plan repair, and (ii) proving planning task unsolvability. We introduce a method allowing to generate red-black plans for arbitrary inputs — intractable red-black planning — and we evaluate its use for (i) and (ii). With (i), our results show promise and outperform standard baselines in several domains. With (ii), we obtain substantial, in some domains dramatic, improvements over the state of the art.
Characteristics of Foreign Direct Investment into Agriculture in Ghana

The paper investigated the characteristics of foreign direct investment( FDI) to Ghana's agriculture by examining the flow of funds, projects, employment and possible pre-independence legacies in FDI inflows from Ghana's former partners in colonial relationships and the slave trade. Using moving averages, percentages, cross tabulations and chi-squares tests, to data from 1994-2010, the following conclusions were drawn; a) FDI flows, measured by estimated cost of projects remained stable and low for most part of 1994-2010. However, huge jumps were witnessed after 2008, coinciding with Ghana's second time of successful and peaceful transfer of political power to another government; b) Clustering of agricultural projects in Greater Accra Region, c) a strong attraction of large FDI firms for the crops subsector; d) 75% of the FDI projects are SMEs; e) Among European countries, Ghana's former slave and colonial masters, Britain, Netherlands and Denmark contribute most FDI projects to Ghana's agriculture. Volta Region has strong attraction for projects from Germany. Strategies need to be designed to attract projects beyond Greater Accra, where poverty reduction may be better felt.&#x0D; Keywords: FDI;Agriculture;Employment;Distribution;Projects.
Factors Affecting Concept Retention

Abstract NOTE: The first page of text has been automatically extracted and included below in lieu of an abstract Factors Affecting Concept Retention Keywords Concept retention, transfer, competencies, fluid mechanics Introduction Few would argue with the claim that the quality of the learning experience in prerequisite coursework has a significant impact on student success in subsequent courses. The premise for this seems obvious: the more effectively students are taught, the better they will learn, and the better they learn, the more they will retain. Surprisingly, the STEM (Science, Technology, Engineering, and Mathematics) education research literature contains minimal evidence to support this premise. Many studies exist that explore how different pedagogies affect student attitudes or self-perceived learning, but few studies in the area of engineering education have been published that report on the link between pedagogy, learning, and knowledge retention. This paper seeks to add to the limited evidence supporting the fundamental premise that pedagogy affects learning, and learning affects retention. Specifically, this paper has two objectives. The first objective is to evaluate how well students retain fundamental fluid mechanics concepts in the long term. The ability to do so is termed concept retention in this paper. The second objective is to evaluate how various factors, including pedagogy, influence student concept retention. This is an exploratory effort and no attempts to generalize will be made. Background It is important to differentiate between transfer, knowledge retention, and concept retention. For this paper, transfer is defined as the ability for learning activities to have positive effects that extend beyond the conditions of initial learning.(1) Knowledge retention is defined as the ability to remember facts and other information. Concept retention is the ability to remember fundamental concepts rather than “just” facts. “Concept retention” is a term coined for this paper, which was necessary as the ability to retain concepts rather than facts has not been differentiated in the literature. These three terms may be better explained with an example. Consider the Bernoulli equation, used in Fluid Mechanics to compare the energy at two points within a fluid. According to the Bernoulli equation, no energy is lost or gained between the two points of interest. This equation is often applied to explain the venturi effect, in which an incompressible fluid traveling through a constriction experiences an increase in velocity and an accompanying decrease in pressure. A test of knowledge retention of the Bernoulli Equation might be to ask students to repeat the equation, or, given the equation, to define the terms in the equation. A test of transfer might be to ask the students to apply the Bernoulli Equation to a case that they have not considered before, for example an orifice meter. A test of concept retention would ask students how the pressure in a constriction would vary as compared to the pressure before or after the constriction. To ensure
Engineering a Live UHD Program from the International Space Station

The first-ever live downlink of ultrahigh-definition (UHD) video from the International Space Station (ISS) was the highlight of a Super Session at the National Association of Broadcasters (NAB) Show in April 2017. UHD is four times the resolution of Full HD or 1080P video. Also referred to as 4K, the UHD video downlink from the ISS all the way to the Las Vegas Convention Center required considerable planning, pushed the limits of conventional video distribution from a spacecraft, and was the first use of High Efficiency Video Coding (HEVC) from a spacecraft. The live event at NAB serves as a pathfinder for more routine downlinks of UHD as well as the use of HEVC for conventional HD downlinks to save bandwidth. A similar demonstration was conducted in 2006 with the Discovery Channel to demonstrate the ability to stream HDTV from the ISS. This paper describes the overall workflow and routing of the UHD video, how audio was synchronized even though the video and audio were received many seconds apart from each other, and how the demonstration paves the way for not only more efficient video distribution from the ISS but also serves as a pathfinder for more complex video distribution from deep space. The paper also describes how a live event was staged when the UHD video coming from the ISS had a latency of 10+ s. In addition, this paper touches on the unique collaboration between the inherently governmental aspects of the ISS, commercial partners Amazon and Elemental, and NAB.
A Family of Constacyclic Codes over 𝔽 <sub>2</sub> <sup> <i>m</i> </sup> + <i>u</i> 𝔽 <sub>2</sub> <sup> <i>m</i> </sup> and Its Application to Quantum Codes

Let R be the ring 𝔽2m + u𝔽2m, where u2 = 0. We introduce a Gray map from R to 𝔽22m and study (1 + u)-constacyclic codes over R. It is proved that the image of a (1 + u)-constacyclic code length n over R under the Gray map is a distance-invariant binary quasicyclic code of index m and length 2mn. We also prove that every code of length 2mn which is the Gray image of cyclic codes over R of length n is permutation equivalent to a binary quasi-cyclic code of index m. Furthermore, a family of quantum error-correcting codes obtained from the Calderbank-Shor-Steane (CSS) construction applied to (1 + u)-constacyclic codes over R.
On the exponents of APN power functions and Sidon sets, sum-free sets, and Dickson polynomials

<p style='text-indent:20px;'>We derive necessary conditions related to the notions, in additive combinatorics, of Sidon sets and sum-free sets, on those exponents <inline-formula><tex-math id="M1">\begin{document}$ d\in {\mathbb Z}/(2^n-1){\mathbb Z} $\end{document}</tex-math></inline-formula>, which are such that <inline-formula><tex-math id="M2">\begin{document}$ F(x) = x^d $\end{document}</tex-math></inline-formula> is an APN function over <inline-formula><tex-math id="M3">\begin{document}$ {\mathbb F}_{2^n} $\end{document}</tex-math></inline-formula> (which is an important cryptographic property). We study to what extent these new conditions may speed up the search for new APN exponents <inline-formula><tex-math id="M4">\begin{document}$ d $\end{document}</tex-math></inline-formula>. We summarize all the necessary conditions that an exponent must satisfy for having a chance of being an APN, including the new conditions presented in this work. Next, we give results up to <inline-formula><tex-math id="M5">\begin{document}$ n = 48 $\end{document}</tex-math></inline-formula>, providing the number of exponents satisfying all the conditions for a function to be APN. <p style='text-indent:20px;'>We also show a new connection between APN exponents and Dickson polynomials: <inline-formula><tex-math id="M6">\begin{document}$ F(x) = x^d $\end{document}</tex-math></inline-formula> is APN if and only if the reciprocal polynomial of the Dickson polynomial of index <inline-formula><tex-math id="M7">\begin{document}$ d $\end{document}</tex-math></inline-formula> is an injective function from <inline-formula><tex-math id="M8">\begin{document}$ \{y\in {\Bbb F}_{2^n}^*; tr_n(y) = 0\} $\end{document}</tex-math></inline-formula> to <inline-formula><tex-math id="M9">\begin{document}$ {\Bbb F}_{2^n}\setminus \{1\} $\end{document}</tex-math></inline-formula>. This also leads to a new and simple connection between Reversed Dickson polynomials and reciprocals of Dickson polynomials in characteristic 2 (which generalizes to every characteristic thanks to a small modification): the squared Reversed Dickson polynomial of some index and the reciprocal of the Dickson polynomial of the same index are equal.
