Two‐stage ANN‐based bidding strategy for a load aggregator using decentralized equivalent rival concept
Authors: Kiannejad Mohammad , Salehizadeh Mohammad Reza , Oloomi‐Buygi Majid 
Published: November 2020

AbstractAs an intermediator between the wholesale electricity market and retail market, a typical load aggregator submits an optimal bid to the system operator to meet the expected demands of its customers. In this regard, the provision of an effective optimal bidding strategy is very crucial for a load aggregator to increase its profit. Within this context, this paper proposes a two‐stage artificial neural network based adaptive bidding strategy procedure for an LA by revealing, modelling, and predicting the aggregative behaviour of the competitors in an hourly electricity market. To this end, we develop the concept of decentralized equivalent rival whose behaviour in the electricity market reflects the aggregation of behaviours of all individual competitors. Also, an equivalent market which its outcomes are approximately equal to those of the real market is modelled. The equivalent market's participants are the load aggregator and its corresponding DER. The proposed approach is capable enough to consider transmission constraints. The performance of the proposed approach has been examined on an illustrative example and the IEEE 30‐bus test system by considering transmission network constraints. The proposed artificial neural network‐based adaptive bidding strategy has compared with a Q –learning‐based bidding approach and the results are analysed.

AbstractThe multi‐terminal hybrid line commutated converter (LCC)/modular multilevel converter (MMC)‐based high voltage dc (HVDC) has been applied to solve the simultaneous commutation failure problem in East China. Here, the propagation of the travelling wave is characterised by transfer functions and the characteristic of the fault current travelling wave in the multi‐terminal hybrid LCC/MMC HVDC system is analysed. Then a directional pilot protection for the multi‐terminal hybrid LCC/MMC HVDC system is proposed. The proposed method is implemented to the designed HCM5000 dc control and protection device and verified in the Kun–Liu–Long three‐terminal hybrid LCC/MMC HVDC real‐time digital simulator (RTDS) test system. The test results show that the proposed method meets the engineering requirement of multi‐terminal hybrid LCC/MMC HVDC system for line protection.
Second-order empathy, pragmatic ambiguity, and irony
Authors: Geeraerts Dirk 
Published: November 2020

Abstract
If first-order empathy is the ability of Self to
take into account Other’s point of view, second-order empathy may be
defined as the ability of Self to take into account Other’s point of
view as including a view of Self. The paper argues that the
possibility for the hearer to choose between a first-order empathic
and a second-order empathic interpretation of speaker utterances
introduces a principled and pervasive indeterminacy in
speaker-hearer interactions, illustrated with examples of
referential ambiguity, speech-act-related ambiguity, and
sociocommunicative ambiguity. With representative speech acts, the
interaction of degree of empathy and convergence/divergence of
beliefs yields six interpretative configurations: assertion,
mistake, agreement, disagreement, irony, deception. Thus, irony
finds a systematic position within a broader calculus of
intersubjective interaction.
The multimodal negotiation of irony and humor in
interaction
Authors: Brône Geert 
Published: November 2020

Abstract
Interactionally grounded accounts of humor and
irony have focused on the construction of complex layered gestalts.
In most cases, these accounts provide a model for the pretense that
speakers are engaged in when jointly construing ironic or humorous
utterances, as well as for the affective power of such utterances.
Much less studied, however, is the question how speakers
interactionally monitor such sequences of joint pretense. To
investigate this more systematically, I zoom in on the role of eye
gaze as a mechanism for reaction monitoring by speakers and hearers.
Using humorous sequences taken from a multimodal video corpus of
three-party interactions, in which the gaze behavior of all
participants was recorded using mobile eye-tracking devices, I
describe specific gaze patterns.
Metaphor and irony
Authors: Barnden John 
Published: November 2020

Abstract
We address metaphor/irony mixing, as in ironic
“What a rocket!” about a very slow train. We
agree that the final meaning is often better viewed as resting
ironically on metaphorical meaning (the train is very fast) than
metaphorically resting on ironic meaning (the train is far from
being a [literal] rocket). However, we discover that matters are
much messier than previously discussed. The reverse meaning
dependence can be supported; it can sometimes be preferable; and
there is parallel mixing, with irony and metaphor mutually
independent. Also, even when hearers do metaphoric processing mostly before
ironic processing, they can benefit from first of all detecting the
utterance’s ironicity. This in turn suggests metaphor processing
that involves contrast-based, as well as similarity-based,
mappings.
On figurative ambiguity, marking, and low-salience
meanings
Authors: Givoni Shir , Bergerbest Dafna , Giora Rachel 
Published: November 2020

Abstract
This paper discusses the phenomenon of marked
ambiguation, when more than one meaning of an ambiguity is
simultaneously applicable, and outlines an account for such marking
within the Low-Salience Marking Hypothesis.
According to this hypothesis, ambiguity markers (e.g.,
double entendre, in the full sense of the word)
boost meanings low on salience (Givoni, 2011; Givoni, Giora, and Bergerbest, 2013). Low-salience
meanings are meanings less frequent, less familiar, less
prototypical, and less conventional (Giora, 1997, 2003). Results from two experiments
conducted in Hebrew support the hypothesis. They show that marking
figurative polysemy results in higher preference and faster response
times for less-salient meanings, challenging modular (Fodor, 1983), literal-first
(Grice, 1975), and
underspecification (Frisson and
Pickering, 2001) accounts of lexical access.
Psycholinguistic approaches to figuration
Authors: Carrol Gareth 
Published: November 2020

Abstract
Figurative language provides a testing bed for
language processing in general, since it requires speakers to
utilize a sophisticated range of linguistic, pragmatic and cognitive
skills to derive an appropriate interpretation. The toolkit of
psycholinguistics, where precise measurements of behavioural
responses help to build a model of underlying cognitive processes,
can enrich our understanding of this complex topic. Two techniques
that have been fruitfully applied to the study of figurative
language are cross-modal priming and eye-tracking. Drawing on a
range of example studies from the literature, this chapter will
demonstrate how figurative language research can benefit from the
application of psycholinguistic techniques. It concludes with a
consideration of how experimental results can be interpreted against
existing theories and models.
Doing justice to the agential material*
Authors: Carpentier Nico 
Published: November 2020

AbstractDiscourse theory has always paid explicit attention to the material dimension of social reality, with, for instance, the dislocation concept attributing an active role to the material. Still, it lacks attention for the specificity of the material-as-material, and tends to attribute a privileged position to the discursive as provider of meaning to these materials. This article argues that there is a need for a critical dialogue between discourse theory and new materialism, leading to the development of non-hierarchical approaches towards the discursive and the material realms. One particular approach, a model that is labelled the discursive-material knot, is proposed and developed in this article. This model expands the discourse-theoretical vocabulary so as to include bridging concepts such as invitation, investment and entextualisation. Moreover, it also allows for the development of new discursive-material research agendas, one of which, in relation to the environment and human-animal relations, is discussed.
“Universal” readings of perfects and iamitives in typological
perspective
Authors: Dahl Östen 
Published: November 2020

Abstract
In Dahl &
Wälchli (2016), we investigate the relationship between
perfects and iamitives – i.e. items whose semantics combines
features of perfects and words like already – using
statistical techniques on data from a multilingual parallel corpus
of Bible texts. This paper looks at the same grammatical domain with
focus on so-called “universal readings” of perfects, several
different subtypes are identified and the cross-linguistic variation
of the distribution of perfects and iamitives as well as other kinds
of marking within them is studied. The types looked at are
combinations with adverbs labeled as duration-quantifying
(for three hours), left-boundary indicating
(since Monday), and universally quantifying
adverbials (always). An overt marking may be
already-related, a non-already-related perfect or non-perfect. In
duration-quantifying and left-boundary contexts, both
already-related and non-already-related markings are found with
variable frequency and zero-marking is common, but already-related
markings in general seldom appear together with perfects. Zero
marking is common. In universally quantifying contexts
already-related marking is rare, but languages in which
non-already-markings are otherwise optional or obligatory tend to
use them obligatorily here.
Perfect and its relatives in Atayal
Authors: Gorbunova Irene 
Published: November 2020

Abstract
This paper is a result of a
typologically-oriented study of the Atayal TMA system. The data is
approached under the framework of the TMA Questionnaire of Dahl (1985). Five markers
that are found in the perfect-related contexts of the Questionnaire
are described in more detail. For each marker it is suggested which
cross-linguistic category type it might represent and how this
language-specific realization fits into known typology for the
category.
The rise of the periphrastic perfect tense in the continental
West Germanic languages
Authors: Broekhuis Hans 
Published: November 2020

Abstract
This article adopts the traditional claim in
Dutch linguistics that periphrastic perfect-tense constructions
gradually developed out of copular-like constructions with
have and be. It argues that this development
was made possible by the introduction of two morphological rules.
The first rule derives verbal (event-denoting) participles from
adjectival (property-denoting) participles, which gave rise to
periphrastic perfect-tense constructions with transitive and
mutative intransitive verbs. At a later stage this rule was replaced
by a rule (still productive in present-day Dutch) that derives
verbal participles from verbal stems, as a result of which the
periphrastic perfect tense spread to non-mutative intransitive
verbs. The article concludes by showing that this account is
superior to Coussé’s
(2008) flexible user-based account within the
constructionist framework, which rejects the categorial distinction
between adjectival and verbal participles.
On the emergence of auxiliary selection in Germanic
Authors: Larsson Ida 
Published: November 2020

Abstract
This paper is concerned with the development of
auxiliary selection in Germanic, i.e. the alternation between
have and be in perfects depending on the type
of lexical verb. It is argued that all of the Germanic languages
first develop a perfect of the modern English type, with
have as the only auxiliary used with all types of
verbs. This early Germanic have-perfect disallowed
positional past time adverbials in the present perfect, and perfect
doubling (see Larsson &
Brandner to appear). In a later development, German,
Dutch, and Danish developed a new perfect with auxiliary selection,
a more extended use of the present perfect, and perfect doubling. It
is suggested that this development is a consequence of the further
grammaticalization of the auxiliary into a semantically weaker
element, spelled out as either have or be (cf.
Kayne 1993). The
emergence of the new perfect leads to competition between two types
of perfects, and to a gradual spread of the new perfect which can be
observed in the historical records.
Terahertz pulse emission from photoexcited bulk crystals of transition metal dichalcogenides
Authors: Nevinskas I , Norkus R , Geižutis A , Kulyuk L , Miku A , Sushkevich K , Krotkus A 
Published: November 2020

Abstract
Multilayer MoS2, MoSe2, and WSe2 crystals were excited with femtosecond optical pulses of various wavelengths. The emitted terahertz (THz) radiation pulses were found to be the most intense at photon energies coinciding with the direct energy gap at the K points of the Brillouin zone of corresponding materials. It was shown that the transition metal dichalcogenides of different dopant type emit THz pulses of opposite polarity, suggesting that the surface field plays a role in THz emission. Nevertheless, the optical pump–THz probe experiments contradicted THz emission observations, demonstrating a decrease in photoconductivity at higher energy quanta. The proposed THz pulse generation mechanism, therefore, assumes the accumulation of excitonic electric dipoles during optical pulse absorption and a fast build-up of the internal electric field inside the samples. This assumption was supported by double optical pulse investigations.
A robust visual odometry based on RGB-D camera in dynamic indoor environments
Authors: Zhang Fangfang , Li Qiyan , Wang Tingting , Ma Tianlei 
Published: November 2020

Abstract
To solve the accurate positioning problem of mobile robots, simultaneous localization and mapping (SLAM) or visual odometry (VO) based on visual information are widely used. However, most visual SLAM or VO cannot meet the accuracy requirements in dynamic indoor environments. This paper proposes a robust visual odometry based on deep learning to eliminate feature points matching error. However, when a camera and dynamic objects are in relative motion, the frames of camera will produce ghosting, especially in high-dynamic environments, which bring additional positioning error; in view of this problem, a novel method based on the average optical flow value of the dynamic region is proposed to identify feature points of the ghosting, and then the feature points of the ghosting and dynamic region are removed. After the remaining feature points are matched, we use a non-linear optimization method to calculate the pose. The proposed algorithm is tested on TUM RGB-D dataset, and the results show that our VO improves the positioning accuracy than other robust SLAM or VO and is strongly robust especially in high-dynamic environments.
Waveguide-integrated niobium- nitride detectors for on-chip quantum nanophotonics
Authors: Mattioli Francesco , Cibella Sara , Gaggero Alessandro , Martini Francesco , Leoni Roberto 
Published: November 2020

Abstract
NbN-based detectors can detect light from the granular regime (single or few photons) up to weak continuous photon fluxes at wavelengths ranging from visible light up to mid-IR. The article reports our recent results on a novel linear detector, the waveguide-integrated hot electron bolometer (HEB) capable to measure photon fluxes of large coherent beams in a regime in which superconducting nanowire single photon detectors (SNSPDs) are not efficient due to their strong nonlinearity. SNSPDs, photon number resolving detectors and amplitude multiplexing readout schemes, all integrated on photonic circuits are also discussed in the paper. The compatibility of the integrated HEB detectors with the SNSPDs technology can allow the characterization of complex non classical states of light within the same chip.

Published: November 2020

Abstract
Environmental friendly and biodegradable plant polysaccharide aerogel filter rods were prepared, and their degradation rate and influence rule under different environmental conditions were investigated. Micro morphology observation and mechanical properties research were carried out. The results showed that Konjac Glucomannan (KGM) had a significant effect on the micro morphology of gelatin aerogel. When KGM was added, the structure of aerogel changed obviously, and the pore size decreased and better pore structure appeared. The optimal ratio of KGM and gelatin is 1:2. The filtration efficiency of K1G2 aerogel is 45.35% for particles with a particle size of 0.3 μm and above. With the increase of particle size, the filtration efficiency of aerogel for particles increases. The filtration resistance is 30 Pa. The permeability of K1G2 aerogel is better.

Published: November 2020

Abstract
The 316L stainless steel elbow used in the pulse soot blower cracked during service, and the cracking occurred at the maximum bending radius of the elbow. There is no obvious plastic deformation at crack and there is much rust deposit on the inner elbow wall of cracked elbow. In order to avoid similar accidents, the methods such as chemical composition analysis, microstructure analysis and crack pattern scanning are adopted to analyze crack reason. The results show that stress corrosion is the main reason to cause crack of 316L stainless steel elbow.

Effect of water glass on setting time and mechanical properties of fly ash slag geopolymer
Authors: Du Tianling , Liu Yin 
Published: November 2020

Abstract
In this paper, the effects of different modulus and content of water glass(sodium silicate solution) on the setting time and mechanical properties of geopolymer were studied, and the internal reaction mechanism was analyzed. Studies show that the setting time (initial setting and final setting) of fly ash slag geopolymers increases with the rise of the modulus of sodium silicate solution, and the compressive strength increases first and then decreases with the rise of the modulus. The optimal modulus range is 1.2 ~ 1.5. With the increase of the water glass content, the setting time of the slurry material becomes shorter. When the water glass content increases to more than 20%, the compressive strength tends to decrease. This article analyzes the hydration and solidification reaction process of the polymer of fly ash slag geopolymer under water glass excitation.
