Academic literature on the topic 'Complex event structure'

Events and Event ProcessesPresented article describes the issues known from the logical structures characterization theory [2] used in this case to describe the events designed for the needs of proper functioning of organizational structures. Necessary formalization is used strictly for the maintenance of the concept discipline. Event theory [5] is used in the designing of complex structures of organizational systems for which the basic necessity is its compliance with the set functional description. Final organization's characteristics are determined by many factors, such as: a) completeness and non-contradiction of the functional specification b) theoretical correctness of the functional transformation of the organization into the design of its organizational structure c) correctness of the technical project realization.

AbstractThis article investigates the syntactic and semantic properties of complex predicates in Persian in order to isolate the individual contributions of the verbal components. The event structure of causative alternation and unergative verbs is determined, based on a decomposition of the verbal construction into primitive syntactic elements consisting of lexical roots and functional heads, with the latter projecting all arguments of the verbal construction. An analysis is provided whereby the argument structure is not projected from the lexicon but is formed compositionally by the conjunction of the primitive components of the complex predicate in syntax. The dual behaviour of Persian complex predicates as lexical and syntactic elements, which has been attested in Persian literature on light verb constructions, follows naturally from the analysis proposed since there is no strict division between the level of word formation and the component manipulating phrasal constructs.

Abstract On 4 July 2022, a complex low-frequency solar radio burst was observed in Metsähovi Radio Observatory of Aalto University. The radio burst was observed at a frequency range between 20 and 80 MHz. In GOES (Geostationary Operational Environmental Satellite) class, the event was classified as C5.1. However, coronal mass ejection (CME) was not associated to this event. The observed radio burst was a long-lasting (~10 minutes) event, and it could be mainly classified as type II solar radio event. Also type III solar events were observed before long-lasting type II event. The event includes common frequency drifting emission structures, both fundamental and harmonic structures, but also rarely observed continuum-like or stationary structure. It is assumed that the continuum-like radio emission structure is originated from the stationary flare (coronal) loop, which was visible over the whole event. The drifting emission structure means accelerated electrons, which are produced by the shock related phenomena. The paper provides the observations from this event on radio wavelength, and also soft-X-ray regime and optical wavelength (AIA 171). In addition, a possible, simplified scenario is presented for forming the drifting and continuum solar radio emissions in type II solar burst.

Recently system security monitoring has meet several challenges. Therefore a system security monitoring approach based on complex event processing and dynamic structure-based neural networks is proposed in this paper. Firstly, complex event processing is used to handle real-time event streams and extract complex events from system security sensors. Secondly, the complex events from CEP would be used for further study by dynamic structure-based neural network. Finally the process of system security monitoring is showed and experiments would be applied to validate the feasibility, efficiency and precision of the approach.

This article analyzes one of the most important features of the revolution — its structure. The author highlights several structures, but the main attention is focusing on the analysis of сonflictological, socio-political and stagе-event structures. In the second part of the article examines the event and step structure of revolutions. In the analysis of chemical structure of revolutions the author compared the approaches of P. Sorokin, C. Brinton, P. Shtompka, other authors and concluded that 1. step structure of such a complex, long and changing socio-political phenomenon, as revolution cannot be adequately described in three or four stages, that «normal» stages of revolutions are the 8–10 stages; 2. for more accurate and detailed descriptions of revolutions must complement structure-stage dust cleaning event; 3. stagе-event structure can be applied both for individual use and together with conflictological and socio-political structures to more adequately describe the complex phenomenon of revolution. From the point of view of the author, the step structure revolution consists of eight defined stages: 1. pre-revolutionary fermentation; 2. revolution in the public consciousness; 3. the revolutionary situation; 4. moderate start of the revolution; 5. a radical extension (switching power to the radical revolutionaries) 6. strong suppression (counter-revolutionary or moderately-revolutionary dictatorship); 7. removing the dictator, the convergence of pre-revolutionary and post-revolutionary values; 8. post-revolutionary reform. Each stage contains certain revolutionary events. These stages and events and make up a stage-event structure of revolution. At the end of the article, the author shows how to use the different investigated them structures can solve applied problems analysis of revolutions, and makes the overall conclusions regarding the first and second part of the article. The main conclusions are that the diversity of revolutions dictates have to analyze multiple structures revolutions, leading from which are сonflictological, socio-political and stage-event structure.

Greenhouse is an important part of facility agriculture and a typical application scenario of modern agricultural technology. The greenhouse environment has the characteristics of nonlinearity, strong coupling, large inertia, and multiple disturbances. There are many environmental factors and it is a typical complex system [7]. In smart greenhouses, control commands are mostly triggered by complex events with multi-dimensional information. In this paper, by building the aggregation structure of complex events in the greenhouse, the technology is applied in the greenhouse as a whole. The core innovations of this paper are as follows: through the analysis of the information transmission process in the greenhouse, combined with the characteristics of the scene, a CEP information structure with predictive modules is formed, which is conducive to the popularization and application of CEP technology in the agricultural field. Pointed out the importance of extreme conditions in the prediction of the greenhouse environment for model evaluation. By improving the loss function in the machine learning algorithm, the prediction performance of a variety of algorithms under this condition has been improved. Applying CEP technology to intelligent greenhouse control scenarios, a set of practical complex event processing systems for greenhouse control has been formed.

Abstract It has been observed that Chinese resultative compounds display varied aspectual behaviors. Yong (1997) distinguishes between simple change resultatives, i.e. resultatives expressing instantaneous change, but allowing a process preliminary to the final change, and complex change resultatives, i.e. those allowing a gradual development of action. Starting from this distinction, this paper aims at providing a structural account of these resultative compounds, based on the constructionist framework put forth by Ramchand (2008), arguing that only simple change resultatives are characterized by having a result layer in their eventive structure. Complex change resultatives, in contrast, are characterized by having the result element in the complement position of the process projection, providing a scalar path. This allows a gradual change of state, and telicity emerges when the path is bounded. The paper also discusses the relation between complex change resultatives and degree achievements.

Warlpiri and Warlmanpa (Ngumpin-Yapa languages of Australia) exhibit a complex predicate construction in which a class of preverbs introduces a single argument that is not shared by the argument structure of the inflecting verb, nor is there necessarily any shared event structure. This is problematic for many theories of linking structures of complex predicates, since no arguments or events are shared between the predicative elements of the complex predicate. The same grammatical relation is instantiated by a beneficiary adjunct. In light of new research in event and argument structure, I propose a lexical rule which introduces an applicative argument to account for the beneficiary construction; and that the preverbs take another predicate as one of their arguments to account for the complex predicates. The applicative rule and the preverbs both introduce an argument of the same grammatical relation, leading to interesting interactions, given that two grammatical relations of the same type are not expected to co-occur within a single clause.

"Până-PPs and Complex Event Constructions in Romanian. This paper examines the syntactic and semantic status of Romanian PPs headed by the morphologically complex prepositions până în/la ʻuntil/as far as/up to in/at’ in VPs of change of location (a pluti până în peșteră ʻfloat up to the caveʼ) and change of state (a munci până la epuizare ʻwork to the point of exhaustionʼ). Contrary to the claims made in the literature (Barbu 2015), the approach taken here argues that these – and other similar – VPs cannot be considered complex event constructions such as goal-of-motion structures and strong resultative constructions, respectively. The discussion revolves around the interpretation of the entire VP, the lack of any type of restriction on the syntactic and semantic classification of the verb, the violation of the Direct Object Restriction, as well as the borderline between these PPs and temporal adjuncts. These properties highlight the fact that the availability of such VPs does not turn Romanian into a satellite-framed language as they are not real counterexamples to the Talmian generalization according to which verb-framed Romanian disallows these two complex event constructions. Keywords: goal-of-motion structure, resultative construction, VP, până-PP, Romanian "

The robotic process mining focuses on the analysis of historical process sequences in order to build up a process model for the investigated field. One of the main tasks in robotic process mining is the construction of process schema for the input sequences. Usual methods are able to generate models using only baseline graph structures. In order to support high level structures like parallelism, the input event sequence structure must support additional attributes on the events. This paper presents a novel approach on sequence segmentation providing an intermediate graph structure which can be used to mine complex graph patterns. The tested prototype system contains a Python-based implementation of the proposed algorithm. In the paper, some tests are shown to illustrate the suitability of the proposed model.
