Published: July 2017

Introduction: Neurogenic stunned myocardium is well described after
aneurysmal subarachnoid hemorrhage. Stress-induced cardiomyopathy (takotsubo
cardiomyopathy) is a form of neurogenic stunned myocardium which is not
common after subarachnoid hemorrhage. We describe a case report of
stress-induced cardiomyopathy (takotsubo cardiomyopathy) after aneurysmal
subarachnoid hemorrhage. Case report: A previously healthy postmenopausal
woman suffered aneurysmal subarachnoid hemorrhage with consequent
hydrocephalus. After external ventricular drainage, craniotomy and aneurysm
of the posterior inferior cerebellar artery clipping, patient developed signs
of acute coronary syndrome with heart failure. Transthoracic echocardiogram
showed left ventricular apical ballooning and hypercontractile basal
segments. On chest radiography bilateral pulmonary infiltrates were seen.
Mechanical ventilation and continuous sedation were started. Five days after,
patient was weaned from mechanical ventilation and extubated. On control
echocardiogram, the signs of apical ballooning syndrome resolved.
Conclusions: This case and review of the literature suggest stress-induced
cardiomyopathy can mimic acute coronary syndrome after aneurysmal
subarachnoid hemorrhage.

Published: July 2017

The study assessed the genetic diversity of pearl millet accessions grown in
Nigeria and India based on morpho-agronomic traits in order to identify
genotypes with superior characters which could be utilized in breeding
programmes. Twenty-four pearl millet accessions were grown and evaluated for
agronomic and morphological traits during the dry and wet seasons of
2015-2016. Data collected on the accessions using standard descriptors were
analysed statistically. IP22281 had the highest mean plant height (108.90 cm)
while NGB00531 recorded the lowest (61.02 cm). Significant intra-specific
variation existed in number of leaves per plant, leaf length, leaf width,
number of nodes and internode length, however, stem girth was similar for the
accessions. Tillering was generally poor with the highest value (1.60 tillers
per plant) found in NGB00531. A significant positive correlation occurred
between plant height, number of leaves, leaf length and leaf width. Panicles
emerged between 44 and 56 days and NGB00548 had the shortest maturity time.
Also, panicle length and peduncle diameter varied significantly for the
accessions. The highest grain yield and 1000-grain weight were recorded in
NGB00616 and the lowest yield and weight were recorded in IP22269. The
principal component analysis grouped the accessions into four clusters,
comprising mixtures of Nigerian and Indian members. Similarly, the dendrogram
grouped the accessions into two main groups which were sub-divided into
smaller clusters with accessions from Nigeria and India in the same cluster.
The study concludes that variations in morpho-agronomic and yield characters
among the accessions studied could be harnessed for crop improvement. The
clustering pattern of these accessions indicated their genetic relatedness,
possibly from the same progenitor, but separation by geographical or
ecological isolation mechanisms.

Authors: Milatovic Dragan , Djurovic Dejan , Zec Gordan
Published: July 2017

Growth and productivity characteristics including: initial and final fruit
set, yield per tree, trunk cross-sectional area, yield efficiency and fruit
weight were studied in ten cultivars of Japanese plums in the Belgrade area
for the period of three years (2013-2015). Initial fruit set ranged from 5.6
to 44.4%, and the final fruit set from 2.6 to 23.36%. The high yield per tree
(over 10 kg) was obtained in cultivars ?Obilnaja? and ?Morettini 355?,
whereas the low yield (under 5 kg) was obtained in cultivars ?Strival?,
?Black Amber?, ?Early Angeleno? and ?Autumn Giant?. The lowest vigor was
observed in the cultivar ?Golden Plum?, and the highest in the cultivar
?Strival?. The majority of cultivars had a very large fruit (over 50 g). The
yield was strongly positively correlated with initial and final fruit set (r
= 0.84**; r = 0.92**, respectively). Fruit weight was moderately negatively
correlated with initial and final fruit set (r = -0.67*; r = -0.63*,
respectively).

Published: July 2017

Effects of mucuna seed extract (MSE) in tris-extenders on sperm functional
integrities and seminal oxidative stress indices of vitrified sperm of West
African Dwarf (WAD) goat bucks were investigated. Varying levels (0, 0.25,
0.5, 0.75, 1 g/100 mL of diluent) of MSE in tris-extenders were diluted with
semen specimens. Diluted semen specimens were vitrified and preserved in
liquid nitrogen. The results showed that sperm functional integrities
(acrosome and membrane integrities) in MSE extenders were comparable.
However, seminal oxidative stress indices (malondialdehyde [MDA] and acrosin
activity) differed (P<0.05) among the various treatments and the control. The
results revealed that semen vitrified with MSE had reduced (P<0.05) MDA
concentrations compared to the control. Higher (P<0.05) acrosin activities
were recorded in semen vitrified with MSE compared to the control except at
0.25g MSE and optimal values were recorded at 1g MSE. The findings indicated
that MSE in the tris-extenders reduced MDA concentration with congruent
elevated acrosin activity and consequently maintained sperm functional
integrities of vitrified spermatozoa of the WAD goat.

Published: July 2017

A field study was carried out in a vegetable research field of the National
Horticultural Research Institute, Ibadan, Nigeria during the late raining
season of 2015 to determine the appropriate okra/legume-based cropping system
that will increase crop yield and farmer?s income. The experiment was
arranged in a randomized complete block design (RCBD) with three (3)
replicates. The treatments comprised intercropping okra with groundnut or
cowpea planted at varying spacings (60 cm x 30 cm, 60 cm x 40 cm, 60 cm x 50
cm and 60 cm x 60cm). Okra was planted at a spacing of 60 cm x 40 cm, the
plot size was 3 m x 2.4 m (7.4 m2). Data collected was subjected to analysis
of variance (ANOVA) and significant means were separated using the least
significant difference (LSD) test at the 5% probability level. Economic
analysis of the cropping mixture was carried out using gross margin analysis,
monetary advantage index and benefit to cost ratio analysis. Results revealed
that the land equivalent ratio (LER) of 1.62 was recorded in okra/groundnut
at 60 cm x 40 cm and LER of 1.74 was observed in okra/cowpea at 60 cm x 30
cm. Okra/cowpea intercropping system spaced at 60 cm x 30 cm was the most
remunerative (N859,192/ha), followed by okra/cowpea spaced at 60 cm x 50 cm
(N744,212/ha) while okra/cowpea spaced at 60 cm x 60 cm was the least
remunerative. The highest gross margin of N2,188,961/ha was obtained in
okra/groundnut spaced at 60 cm x 40 cm. The least return was obtained in
okra/groundnut spaced at 60 cm x 60 cm (N700,103/ha). The economic analysis
revealed that okra/cowpea spaced at 60 cm x 30 cm produced the highest gross
margin of N859,192/ha and monetary advantage index of N450,447/ha while
okra/groundnut spaced at 60 cm x 40 cm gave the highest gross margin of
N2,188,961/ha and monetary advantage index of N924,642/ha.
Strategic Disclosures of Litigation Loss Contingencies When Customer-Supplier Relationships Are at Risk
Authors: Cen Ling , Chen Feng , Hou Yu , Richardson Gordon D.
Published: July 2017

In the presence of litigation-facing suppliers, the supply chain relationship is at risk. Suppliers with principal customers (dependent suppliers) have a higher concentration of sales to customers, and they are more at risk relative to suppliers without principal customers (non-dependent suppliers). As a result, we predict and find that litigation disclosure patterns differ for the two supplier types: dependent suppliers are more likely to delay bad news and accelerate good news related to litigation outcomes, compared to non-dependent suppliers. Such strategic disclosure patterns in our end-game setting are opposite to those documented in the existing supply chain literature for the repeated-game setting (for example, Hui, Klasa, and Yeung 2012).

Implied Cost of Equity Capital Estimates as Predictors of Accounting Returns and Stock Returns
Authors: Larocque Stephannie A. , Lyle Matthew R.
Published: July 2017

Using a popular return decomposition, we show that expected returns should on average be positively associated with future return on equity (ROE), controlling for the book-to-market ratio (BM). However, we find that none of the commonly used implied cost of equity capital estimates (ICCs), which proxy for expected returns, are positively associated with future ROE. This lack of association with future accounting returns appears to affect the ability of ICCs to forecast future stock returns: ICCs do not provide information about future stock returns incremental to that contained in a linear combination of current ROE and BM. Our findings suggest that tractable accounting-based models that linearly combine BM and ROE, or other accounting-based variables, offer improvements on extant ICCs as expected returns proxies.

Authors: Hamarashid Hozan Khalid , Saeed Miran Hama Rahim , Saeed Soran
Published: July 2017

Nowadays, traffic light system is very important to avoid car crashes and arrange traffic load. In the Sulaimani City / Iraq, there are many traffic problems such as traffic congestion or traffic jam and the amount of time provided manually to the traffic light system. This is the main difficulty that we try to solve. The traffic lights exist but still do not manage traffic congestion due to the fixed time provided for each lane regardless of their different load. Therefore, we are proposing to change the traditional traffic system to smart traffic system (adaptive system). This paper Focuses on the existing system (fixed system), then propose the adaptive one. The main crucial side effects of the existing system are:

 

Emergency cases: congested traffics might block the way of emergencies for instance ambulance, which transports people to the hospital

Wasting time of people generally and specially

Delays, which lead people to not to be punctual, this means people arrive late to the work

 Wasting more fuels as staying more in the traffics, which affects the environment by increasing pollution.

Energy Conversion with Doubly Fed Machines.
Authors: J. Bendl, M. Chomat  , L. Schreier
Published: July 2017

The presented paper deals with doubly fed machines (DFM) operating in units that convert mechanical to electric power and vice versa. We concentrate especially on their usage in pumped storage plants which, used in the power system, can increase its stability and operating efficiency. A mathematical model of the power unit with a doubly fed machine and a cycloconverter in its rotor circuit was derived. The model includes vector control of the rotor voltage which enables us to analyse both steady and transient states.
Heat Transfer Modelling in a Circulating Fluidised Bed Biomass Boiler.
Authors: Alexandre Aibéo  , Carlos Pinho
Published: July 2017

A numerical procedure for heat transfer in a circulating fluidised bed boilers (CFBB) is presented. The riser of these units has, typically, a low height to width ratio, of order of ten, and low net solids flux. Refractory walls involve the bottom bed and two membrane walls are use to confine a square cross-section conduct that works as the riser of the CFBB. The considered unit uses group B particles according to the Geldart classification, with mean diameters of 500 µm and density of 2500 kg/m3 .
The present work is part of a combined effort to develop a complete numerical package to be used in the design of CFB boilers. It only concerns the different features of the heat transfer in CFBB, namely heat transfer coefficients, temperature profiles, its dependencies on fluid dynamic and combustion models, and the calculation of the total thermal power output. The fluid dynamic and combustion models were developed by other teams.
Fluidised bed heat transfer occurs essentially by two mechanisms: convection and radiation and despite showing a complex coupling, they are usually assumed as additive. A CFBB is a complex system, constituted by three main parts: the riser, where the combustion occurs and the particles are fluidised and transported; the cyclone, with the purpose of separating the particles from the gas flow and the downcomer, providing the recirculation of the material back to the riser. The present work concerns only the riser, where the majority of the heat transfer occurs. Considering the dynamic structure of the riser, the heat transfer is present in three different fronts: from nucleus towards annulus, from nucleus towards the wall through the annulus, and directly from annulus to the wall. Except for beds with low particle concentration values, convection is the dominant mechanism (Breitholz and Leckner, 1997).
The numerical procedure is applied in layers of infinitesimal height, in order to be possible to solve the energy, the momentum and the continuity equations, and an irregular mesh was used. The bubbling portion of the bed and the splash zone are composed, each one, by a single layer; this approach is a function of the hydrodynamic model upon which the heat transfer model is based. For the core-annulus zone, two columns of infinitesimal layers were used. In fact several meshes are used, concerning fluid-dynamic properties, heat transfer properties and geometrical features.

Published: July 2017

In a view to reduce a long time series of several variables into typical days we present in this paper a method for classification of global irradiance days according to different weather classes. To do it we have used the fractal dimension as a basic criterion in the classification. The method which defines fractal dimensions thresholds using the cumulative function leads to classify the days of two Algerian sites into 3 classes: clear sky day, partially clouded sky day and clouded sky day.
Control strategies for active power filters
Authors: F. Barrero  , E. Romero  , M. I. Milanés
Published: July 2017

In this paper a comparison between strategies for extracting the three-phase reference currents for active power filters is shown. The performance of these strategies will be evaluated under different source and load conditions. The study has been applied to a three-phase four-wire system in order to include imbalance.
It will be shown that under balanced and sinusoidal voltages, harmonic cancellation and reactive power compensation can be achieved by all the methods. However, when the voltages are distorted and/or unbalanced, the compensation capabilities are not equivalent.
It will be proved that some strategies do not offer an adequate solution when the mains are not ideal, including harmonics or imbalance.

Published: July 2017

Power industry has been experiencing dramatic changes from a vertically integrated industry into a deregulated competitive electricity market over the last decade. In a restructured electricity industry, markets govern the operation and expansion of electricity generation, and power plants make profits from markets for energy and ancillary services. In the last years there has been a worldwide trend toward restructuring the electricity supply industry and consequently energy markets were created. Ancillary services are defined as all those activities on the interconnected grid that are necessary to support the power transmission and withstand the security operation as well as the power quality level.
This paper presents the most important ancillary services provided by the independent system operator in a restructured power system. It will be also described the Simultaneous Optimisation algorithm to performer the active power reserves dispatch in a competitive environment.
Harmonic Distortion Analysis of a Micro Gas Turbine Interconnected to the Electricity Grid.
Authors: J.C. Bruno  , Ll. Massagués  , A. Coronas
Published: July 2017

Micro gas turbines have opened new opportunities for integrated energy systems using thermally activated technologies for waste heat recovery, improved overall efficiency and reduced emissions in commercial buildings and other small-scale polygeneration applications. However some issues are still unclear, such as the legal and technical issues regarding the electric grid interconnection. In this paper both issues will be addressed from the point of view of the electric system protections and the power quality supply with respect to harmonic distortion. The objective is to provide data and analyse the harmonic distortion of a low-pressure natural gas micro gas turbine of 28 kWe interconnected to the grid. Additionally the main interconnection requirements and protection systems will be described. The studied micro gas turbine cogeneration system is located in the Technological Innovation Centre CREVER at the University Rovira i Virgili in Tarragona (Spain). The results obtained show that the harmonic distortion is clearly below the limits recommended by the existing international standards. Also the already built-in microturbine interconnection protections are enough to assure the correct operation and safety of the micro turbine system and the external grid. However increased communications and automation will be required to manage large amounts of distributed micro gas turbines generation systems connected to the grid.

Standard Test Protocol to Characterize Adjustable Speed Drive Behavior During Voltage Dips.
Authors: M. Teixidó  , A. Sumper  , Q. López  , S. Galceran  , J. Sánchez
Published: July 2017

Susceptibility of adjustable speed drives (ASD) against voltage dips it’s been a red-hot issue in the last years. European standards concerning electromagnetic compatibility in the section of voltage dips don’t allow characterization of ASD performance when a voltage dip occurs. Papers published about this subject are focused on the theoretical study of the effects of dips on ASD and alternative methods for testing voltage dip immunity of this equipment. But in the former, only undervoltage trip has been usually taken into account; and, in the latter, the criterion used to decide when the ASD fails is not suitable in all cases. Firstly this paper will briefly analyze why an ASD trips when there is a voltage dip. Secondly a test will be proposed with two main goals: (a) to offer a novel, simplified and affordable test protocol, and (b) to achieve test results useful for ASD users. To accomplish this second goal, energetic inmunity and control inmunity will be introduced to take into account process necessities where ASD is integrated.
Fuel Cell Based Distributed Generation Feeding Electrical and Thermal Loads.
Authors: S. Meo  , S. MeoG. Paparo  , G.Velotto
Published: July 2017

The progressive deregulamentation of the electrical energy market, together with the incentive to use zero emission energy sources, can encourage, in the middle term, the diffusion of generation sites dispersed on the territory. The utilization of cogeneration in civil and industrial installation and the technological progress associated to small and medium size systems involve increasing requests of linking to the LV and MV distribution grid, which modifies itself from “passive” to “active”. Fuel Cell based electrical distributed sources, suitable to feed also thermal requirements, make the distribution utilities able to satisfy the customer requirements in terms of electrical and thermal loads, creating the opportunities to reconfigure the relation among producer, distributor and customer. The paper focuses on the performances of fuel cell sources and on their integration in the distribution networks, examining the benefits that fuel cell sources could determine on system potentialities in terms of technical and reliability aspects

Published: July 2017

Outside-spin brushless D.C. motors are an alternative to conventional D.C. brush permanent magnet motors, especially in applications that require low power and costs and in which high inertia effects are advantageous. This paper presents a procedure for computing power losses in these kinds of machines. Expressions are derived for predicting copper losses, power interrupter losses, stator iron losses in the tooth and in the yoke, mechanical losses, friction and windage. Stray load losses are also considered and evaluated from previous measurements in outside-spin brushless D.C. motors. The results obtained from the approach proposed are compared to those measured on existing motors, showing a good agreement

One aspect that needs to be studied more deeply about the village administration in the era of village autonomy is the ability of the human resources in the management of village government in accordance village governance objectives and the demands of, “Undang – undang no 06 Tahun 2014 about the village. The capacity of the village government deemed not qualified to run the authority possessed by law the village. Weak capacity of rural government impact on law implementation failure that led to the poor rural village development. This study examines these issues. This study used qualitative research methods. The unit of analysis of this research that the village government Landungsari Dau District of Malang, East Java. This study was conducted over three years (2016, 2017, 2018). The findings of the research during the last four months in the first year of the study is Landungsari village administration showed a good performance in governance at the village of village autonomy era (the era of the Village Law. The village government is able to carry out rural development planning, village administrative governance, and the financial management of the village properly. Nevertheless, the village government also faces serious problems is the lack of human resource capacity of the village administration, village very less quantity, and village officials do not understand the duties of each. To address these issues, the village government seeks to organize village governance based on information technology (e-government), but the effort has not worked well because the village government does not have a human resources professional in the field of information technology and the village government does not have enough budget to develop the e-government program. Therefore, the research team conducting FGD on the development of e-government program. FGD village government resulted in an agreement in cooperation with governmental science labs and e-government program APBDes budgeted in fiscal year 2017. Step next phase is the research team conducting FGD Phase II to design e-government as a means of governance villages effective and efficient, to disseminate the e-government, and publishes scientific articles on the model of governance based rural e-government in the Journal of Politics and Government Muhammadiyah University of Yogyakarta. Our advice as a researcher is a village government should make regulations governing Internet-based mechanism of public services (e-government).

Published: July 2017

This study aimed to analyze the internal and external factors in Ponorogonese society that affect the economical development of sharia in Ponorogo. Methods of data analysis used in this study were the validity test, reliability test, test of multiple linear regression analysis, t-test and F test. The population in this study were all customers of Islamic banks. Because of the study population was quite a lot, then the data collection sample of 110 respondents used sample random sampling technique. The results of the analysis showed that from multiple linear regression test, the obtained value of Adjusted R Square was 0.554, which meant the independent variables influence a client's decision were about 82.4%, and 17.6% were influenced by the other independent factors beyond the research. The dominant factor influencing the customer's decision to use a product of Islamic banks was the motivation of customers that was 53.9%..
PELUANG DAN TANTANGAN DALAM PENGELOLAAN WAKAF

There is a strong tremendous financial owned by Muslims. He was able to change the living standards of people in a short time. As an example, with their awareness of the tithes paying, we see none of the poor, orphans and Muslims were hungry the whole day of Eid al-Fitr, even sometimes it was excessive and difficult to share. Moreover, if the Muslims are aware of the infaq (waqf) and alms, the welfare, prosperity, security and comforts of life will be realized. Endowment is not a new thing. It is a legacy of the Prophet which is very beneficial in the history of Islam. Waqf is a terrible practice with benefits and rewards flowing endlessly. Therefore, endowments must be managed professionally, transparantly and accountably.

Published: July 2017

Objetivo. El tianguis de Pátzcuaro se analiza desde la perspectiva multidisciplinaria del Metabolismo Social, desde la época precolombina hasta la actualidad. Se enfatizan las fases de circulación y consumo para conocer sus cambios y permanencias y los posibles factores que inciden para que siga existiendo. Metodología. A partir de información del archivo histórico de la región, revisión bibliográfica, entrevistas a participantes del mercado, así como observación participante reciente, se aborda el metabolismo social y se destacan dos de sus fases: consumo y circulación. Resultados. El mercado ha ofrecido una diversidad de bienes y el 99% de los asistentes realiza trueque bajo reglas consuetudinarias. El maíz es el producto más solicitado. La oferta de productos ha cambiado por múltiples factores entre los que se encuentra el continuo cambio sociocultural y la disponibilidad, pero se mantienen elementos de una cultura alimentaria que es parte de su identidad y necesidades. Limitaciones y conclusiones. Desde el surgimiento de este mercado hasta su condición actual, las dinámicas y formas económicas que incluyen desde la apropiación y transformación de los recursos naturales, así como las formas de circulación y consumo, se podrían considerar artesanales y tradicionales, de baja escala, escaso uso de maquinaria y capital y predominancia de fuerza de trabajo propia. El intercambio a través del trueque se desarrolla en un contexto de economía solidaria que repercute en la pervivencia del mercado. Se evidencia la necesidad de generar investigaciones que profundicen la información del resto de las fases.
Nonlinear Hybrid Planning with Deep Net Learned Transition Models and Mixed-Integer Linear Programming
Authors: Say Buser , Wu Ga , Zhou Yu Qing , Sanner Scott
Published: July 2017

In many real-world hybrid (mixed discrete continuous) planning problems such as Reservoir Control, Heating, Ventilation and Air Conditioning (HVAC), and Navigation, it is difficult to obtain a model of the complex nonlinear dynamics that govern state evolution. However, the ubiquity of modern sensors allow us to collect large quantities of data from each of these complex systems and build accurate, nonlinear deep network models of their state transitions. But there remains one major problem for the task of control -- how can we plan with deep network learned transition models without resorting to Monte Carlo Tree Search and other black-box transition model techniques that ignore model structure and do not easily extend to mixed discrete and continuous domains? In this paper, we make the critical observation that the popular Rectified Linear Unit (ReLU) transfer function for deep networks not only allows accurate nonlinear deep net model learning, but also permits a direct compilation of the deep network transition model to a Mixed-Integer Linear Program (MILP) encoding in a planner we call Hybrid Deep MILP Planning (HD-MILP-PLAN). We identify deep net specific optimizations and a simple sparsification method for HD-MILP-PLAN that improve performance over a naive encoding, and show that we are able to plan optimally with respect to the learned deep network.
Answering Conjunctive Regular Path Queries over Guarded Existential Rules

Published: July 2017

Ontology-mediated query answering is concerned with the problem of answering queries over knowledge bases consisting of a database instance and an ontology. While most work in the area focuses on conjunctive queries, navigational queries are gaining increasing attention. In this paper, we investigate the complexity of answering two-way conjunctive regular path queries (CRPQs) over knowledge bases whose ontology is given by a set of guarded existential rules. We first consider the subclass of linear existential rules and show that CRPQ answering is EXPTIME-complete in combined complexity and NL-complete in data complexity, matching the recently established bounds for answering non-conjunctive RPQs. For guarded rules, we provide a non-trivial reduction to the linear case, which allows us to show that the complexity of CRPQ answering is the same as for plain conjunctive queries, namely, 2EXPTIME-complete in combined complexity and PTIME-complete in data complexity.
A General Notion of Equivalence for Abstract Argumentation
Authors: Baumann Ringo , Dvořák Wolfgang , Linsbichler Thomas , Woltran Stefan
Published: July 2017

We introduce a parametrized equivalence notion for abstract argumentation that subsumes standard and strong equivalence as corner cases. Under this notion, two argumentation frameworks are equivalent if they deliver the same extensions under any addition of arguments and attacks that do not affect a given set of core arguments. As we will see, this notion of equivalence nicely captures the concept of local simplifications. We provide exact characterizations and complexity results for deciding our new notion of equivalence.
Pareto Optimal Allocation under Uncertain Preferences
Authors: Aziz Haris , de Haan Ronald , Rastegari Baharak
Published: July 2017

The assignment problem is one of the most well-studied settings in social choice, matching, and discrete allocation. We consider this problem with the additional feature that agents' preferences involve uncertainty. The setting with uncertainty leads to a number of interesting questions including the following ones. How to compute an assignment with the highest probability of being Pareto optimal? What is the complexity of computing the probability that a given assignment is Pareto optimal? Does there exist an assignment that is Pareto optimal with probability one? We consider these problems under two natural uncertainty models: (1) the lottery model in which each agent has an independent probability distribution over linear orders and (2) the joint probability model that involves a joint probability distribution over preference profiles. For both of these models, we present a number of algorithmic and complexity results highlighting the difference and similarities in the complexity of the two models.
Strong Inconsistency in Nonmonotonic Reasoning
Authors: Brewka Gerhard , Thimm Matthias , Ulbricht Markus
Published: July 2017

Minimal inconsistent subsets of knowledge bases play an important role in classical logics, most notably for repair and inconsistency measurement. It turns out that for nonmonotonic reasoning a stronger notion is needed. In this paper we develop such a notion, called strong inconsistency. We show that—in an arbitrary logic, monotonic or not—minimal strongly inconsistent subsets play the same role as minimal inconsistent subsets in classical reasoning. In particular, we show that the well-known classical duality between hitting sets of minimal inconsistent subsets and maximal consistent subsets generalizes to arbitrary logics if the strong notion of inconsistency is used. We investigate the complexity of various related reasoning problems and present a generic algorithm for computing minimal strongly inconsistent subsets of a knowledge base. We also demonstrate the potential of our new notion for applications, focusing on repair and inconsistency measurement.
Detecting Chase (Non)Termination for Existential Rules with Disjunctions
Authors: Carral David , Dragoste Irina , Krötzsch Markus
Published: July 2017

The restricted chase is a sound and complete algorithm for conjunctive query answering over ontologies of disjunctive existential rules. We develop acyclicity conditions to ensure its termination. Our criteria cannot always detect termination (the problem is undecidable), and we develop the first cyclicity criteria to show non-termination of the restricted chase. Experiments on real-world ontologies show that our acyclicity notions improve significantly over known criteria.
An Algorithm for Constructing and Solving Imperfect Recall Abstractions of Large Extensive-Form Games
Authors: Cermak Jiri , Bošanský Branislav , Lisý Viliam
Published: July 2017

We solve large two-player zero-sum extensive-form games with perfect recall. We propose a new algorithm based on fictitious play that significantly reduces memory requirements for storing average strategies. The key feature is exploiting imperfect recall abstractions while preserving the convergence rate and guarantees of fictitious play applied directly to the perfect recall game. The algorithm creates a coarse imperfect recall abstraction of the perfect recall game and automatically refines its information set structure only where the imperfect recall might cause problems. Experimental evaluation shows that our novel algorithm is able to solve a simplified poker game with 7.10^5 information sets using an abstracted game with only 1.8% of information sets of the original game. Additional experiments on poker and randomly generated games suggest that the relative size of the abstraction decreases as the size of the solved games increases.
Bounded Timed Propositional Temporal Logic with Past Captures Timeline-based Planning with Bounded Constraints
Authors: Della Monica Dario , Gigante Nicola , Montanari Angelo , Sala Pietro , Sciavicco Guido
Published: July 2017

Within the timeline-based framework, planning problems are modeled as sets of independent, but interacting, components whose behavior over time is described by a set of temporal constraints. Timeline-based planning is being used successfully in a number of complex tasks, but its theoretical properties are not so well studied. In particular, while it is known that Linear Temporal Logic (LTL) can capture classical action-based planning, a similar logical characterization was not available for timeline-based planning formalisms. This paper shows that timeline-based planning with bounded temporal constraints can be captured by a bounded version of Timed Propositional Temporal Logic, augmented with past operators, which is an extension of LTL originally designed for the verification of real-time systems. As a byproduct, we get that the proposed logic is expressive enough to capture temporal action-based planning problems.
What Can You Do with a Rock? Affordance Extraction via Word Embeddings
Authors: Fulda Nancy , Ricks Daniel , Murdoch Ben , Wingate David
Published: July 2017

Autonomous agents must often detect affordances: the set of behaviors enabled by a situation. Affordance extraction is particularly helpful in domains with large action spaces, allowing the agent to prune its search space by avoiding futile behaviors. This paper presents a method for affordance extraction via word embeddings trained on a tagged Wikipedia corpus. The resulting word vectors are treated as a common knowledge database which can be queried using linear algebra. We apply this method to a reinforcement learning agent in a text-only environment and show that affordance-based action selection improves performance in most cases. Our method increases the computational complexity of each learning step but significantly reduces the total number of steps needed. In addition, the agent's action selections begin to resemble those a human would choose.
Revisiting Unrestricted Rebut and Preferences in Structured Argumentation.
Authors: Heyninck Jesse , Straßer Christian
Published: July 2017

In structured argumentation frameworks such as ASPIC+, rebuts are only allowed in conclusions produced by defeasible rules. This has been criticized as counter-intuitive especially in dialectical contexts. In this paper we show that ASPIC-, a system allowing for unrestricted rebuts, suffers from contamination problems. We remedy this shortcoming by generalizing the attack rule of unrestricted rebut. Our resulting system satisfies the usual rationality postulates for prioritized rule bases.
