This article puts forward object-oriented Petri net modeling method, which possesses good encapsulation and modularity compared with current ordinary modeling method. On the macro level, it divides the re-entrant lines into different object modules according to the technology, so that the complexity of models is largely reduced through message delivery between objects. In the micro level, it explains objects' internal operational mechanism, in another word, each object's internal operation cannot be affected by other objects and environment. At last, it makes modeling and dynamic analysis by taking LED chips' processing flow for example, showing that re-entrant lines model based on object-oriented Petri net possesses good modeling ability.

Abstract The study is dedicated to High Level Architecture (HLA) standard for software architecture of interoperable distributed simulations. The paper discusses the differences between object-oriented programming and HLA. It presents an extended simulation architecture providing a mechanism for HLA data exchange through Object-Oriented (OO) objects. This eliminates the complex network programming for HLA distributed simulations. The paper shows a sample code that implements the architecture for OO HLA/RTI simulation.

Background difference method [1] is one of the effective paths of improving robot’s vision reaction ability, and robots use background difference method to find the moving object in vision range and conduct tracking monitoring of moving objects. Then it uses support vector to conduct learning fitting of moving object, which can effectively predict the moving trend of moving object, and then it fabricates corresponding decision programs to conduct intercept capture of moving objects.

The phrase ‘the object of history’ may mean all sorts of things. In this article, a distinction is made between object1, the object of study for historians, and object2, the goal or purpose of the study of history. Within object2, a distinction is made between a goal intrinsic to the study of history (object2in) and an extrinsic goal (object2ex), the latter being what the study of history should contribute to society (or anything else outside itself). The main point of the article, which is illustrated by a discussion of the work of R. G. Collingwood, E. H. Carr, and G. R. Elton, is that in the work of historians and philosophers of history, these kinds of ‘object of history’ are usually (closely) connected. If they are not, something is wrong. That does not mean, however, that historians or even philosophers of history are always aware of these connections. For that reason, the distinctions made in this article provide a useful analytical tool for historians and theorists of history alike.

Object detection is a computer technology related to computer vision and image processing that deals with detecting instances of semantic objects of a certain class (such as humans, buildings, or cars) in digital images and videos. In this domain of object detection, it includes many detecting methods , such as face detection and also pedestrian detection. Object detection has applications in huge areas of computer vision, which includes image retrieval, video surveillance. Deep Neural methods in object detection using one-stage processes generally include di erent versions of YOLO and SSD. The paper which we are publishing here we are comparing some the image detection algorithms. In this project we are going to develop a system for visually impaired people for assisting them in their daily work and give them a free life.

ABSTRACTObservational/correlational research has established that children in stage 5 object permanence development use words that refer to the visible movement of objects, while it is not until stage 6 that they use words referring to the invisible movement of objects (e.g. gone). It is not clear, however, whether the cognitive competence evidenced by performance in the object permanence task is a prerequisite for these linguistic productions or whether they both emerge simultaneously from some underlying representation. The current study used a lexical training paradigm to teach object words, visible movement words, and invisible movement words to children at stage 5 and stage 6 object permanence development. Stage 6 children learned all three types of words equally well. Stage 5 children learned object and visible movement words, especially in comprehension, but did not learn the invisible movement word. These results indicate that the cognitive structures underlying performance in the object permanence task are genuine prerequisites for learning these types of words.

Object-oriented analysis is the activity of understanding a problem domain and developing a specification for it within an object-oriented paradigm. In this paper we propose object-oriented analysis can be viewed as a design task that consists of analysis, synthesis and internal and external completeness and consistency checking. We postulate a blackboard based design framework and propose several alternative theories within this framework. Data from an expert analyst is collected and analyzed for relative explanatory power of the alternative theories. Basic findings are that viewed as a design activity, object-oriented analysis is neither top-down nor completely opportunistic in nature, Rather, (1) analysis (the process of finding objects and processes) and synthesis (constructing the object model and state-transition diagrams) are complementary activities while internal completeness and consistency checking is coupled with synthesis and (2) construction of objects and processes are cyclic and complementary processes. The findings are compared with both descriptive and normative research in automated software design.

A dynamic image has a distinct quantity of object movement from one to another. It can be any object such as a car, person, an object moving from one point X to another point Y. Image consists of a sense of movement. Applications of object tracking are biometrics tracking, AR uses, video surveillance, passage monitoring, vehicle navigation, etc. Challenges in tracking multifaceted objects are fast movement, geometric conversion, blurring, messy background, artifacts, etc. To resolve this problem by merge all small features with nearby texture features. Texture feature describes the plane space and configuration of an area. A mixture of color and texture feature improves the object details and to increase the strength of the object's illustration. In Existing methods such as binary pattern method all object features are removed, so it is difficult to predict the exact pixel movement. The proposed method of improved binary pattern is also tracking the small changes in the pixel difference in one frame to other. Compared with the existing algorithms, IBP method measures the spatial arrangement of local image texture which reduces the overall processing cost and improves the strength of objective image. To track the similarities and difference of the object in each and every frame efficiently and effectively Improved Local Binary Pattern tracking algorithm was proposed. This proposed technique is an effective way to analysis complicated real time situations compared with other methods.

We investigated whether adults and infants aged 3, 5, and 9 months perceive the unity and boundaries of visible objects in accord with the Gestalt relations of color and texture similarity, good continuation, or good form. Adults and infants were presented with simple but unfamiliar displays in which all three Gestalt relations specified either one object or two objects—perception of the objects was assessed by a verbal rating method in the adults and by a preferential looking method in the infants. The Gestalt relations appeared to influence the adults' perceptions strongly. However, the relations appeared to have no effect on the perceptions of 3-month-old infants and weak effects on the perceptions of 5-month-old and 9-month-old infants. The findings support the suggestion that developmental changes in object perception occur slowly. These changes, and the organizational phenomena to which Gestalt psychology called attention, may depend in part on the child's developing ability to recognize objects of particular kinds.

There is considerable evidence that there are anatomically and functionally distinct pathways for action and object recognition. However, little is known about how information about action and objects is integrated. This study provides fMRI evidence for task-based selection of brain regions associated with action and object processing, and on how the congruency between the action and the object modulates neural response. Participants viewed videos of objects used in congruent or incongruent actions and attended either to the action or the object in a one-back procedure. Attending to the action led to increased responses in a fronto-parietal action-associated network. Attending to the object activated regions within a fronto-inferior temporal network. Stronger responses for congruent action–object clips occurred in bilateral parietal, inferior temporal, and putamen. Distinct cortical and thalamic regions were modulated by congruency in the different tasks. The results suggest that (i) selective attention to action and object information is mediated through separate networks, (ii) object–action congruency evokes responses in action planning regions, and (iii) the selective activation of nuclei within the thalamus provides a mechanism to integrate task goals in relation to the congruency of the perceptual information presented to the observer.

Abstract Lessons on common objects, known as ‘object lessons’, were a customary occurrence in Victorian schoolrooms. This article looks at Victorian object lessons around mid-century as a means of examining the variety of meanings that common objects, and particularly manufactured objects, might have held both inside and outside Victorian schoolrooms. While model scripts for object lessons circulated widely and clarified the meaning of common objects in print, the objects themselves had the potential to complicate and challenge these meanings. Drawing primarily on publications by Elizabeth Mayo and the Home and Colonial School Society (established in 1836), this article outlines the theological, industrial and imperialist ways of looking that informed the model object lesson. Yet close study of the objects employed in object lessons – feathers, an object lesson specimen box, and a series of illustrations of animals – demonstrates how full sensory engagement with material objects can disrupt these disciplined ways of looking and learning. The final section of the article describes the decline of object lesson pedagogies once they were established within the official curriculum for England and Wales over the course of the 1880s and 1890s. Increasingly, pictures and nature study came to replace common objects in Victorian schoolrooms, and had their own implications for the ways that schoolchildren were taught to look at and learn from the world around them.

The problem of creating electrochemical devices and the issues that arise in the system of the primary converterobject of control are considered. Low-resistance (salt solutions) and high-resistance (sugar solutions) objects were selected as the subject of study. To solve the problem, we have applied the method of impedance spectrum analysis with EIS Spectrum Analyzer software, which performs modeling on the Levenberg-Marquardt algorithm. Substitution schemes in different frequency and concentration ranges of studied objects were synthesized. This enables appropriate corrective action to minimize the impact of adverse events in the system while monitoring the quality of solutions - non-electrical nature objects – by electrochemical devices.

The aim of this paper is to analyse the displacement phenomena the direct and indirect objects in the English Double Object Construction (DOC) can undergo. The focus is on the movement out of the DOC to the sentence initial position. The analysis concerns not only globally acceptable Goal-Theme object sequence but also the Theme-Goal DOC, which grammaticality is restricted only to a few British English dialects. The processes affecting the objects in the Prepositional Construction are also mentioned. The initial part of the paper is devoted to the underlying syntactic representations of the DOC in English. Following, e.g. Citko (2011), Cuervo (2003), Pylkkännen (2002, 2008), a representation with the Low Applicative Phrase has been adopted. The exact case valuation mechanism for relevant objects (as proposed by Bondaruk and Bartczak-Meszyńska (2014)) has been established. The remaining part of this paper contains a detailed discussion of the derivation of particular object initial sentences with the DOC in the active and in the passive and the interplay between passivisation and topicalisation, as the triggers of the object fronting.

Abstract This paper argues that there is nothing “differential” in the licensing conditions of Differential Object Marking and outlines an analysis that unifies dom with dative object marking and with a broader set of “derived object”-marking configurations. We show that neither morphological nor syntactic distinctiveness can be the driving force for dom: accounts of dom as a morphological distinctiveness device are inadequate diachronically and very unefficient functionally. Syntactic analyses that postulate DP-internal differences or construction-specific double-licensing conditions fail to capture the basic fact that dom is a relation between the objects and the predicates selecting them. Precisely, the burden of our unified explanation falls on the checking requirements imposed to the DP complements by the structural heads selecting them.

The present paper explores Differential Object Marking in a variety of Asturian (Western Iberian Romance) spoken in western Asturias (northwestern Spain). This ancestral form of speech stands out from Central Asturian and especially from Standard Spanish. For a number of reasons, ranging from profound changes in pronunciation, vocabulary, morphology and information structure to slight but very relevant effects on syntax. The main goal of this study is to examine the special marking of direct objects in order to find out what triggers the distribution of Differential Object Marking in this variety. To this aim, this paper will examine, from a variationist perspective, the influence of a number of semantic and discourse-pragmatic parameters on the marking of direct objects in this Western Asturian language as well as in Standard Spanish 1 and Central Asturian (which is generally considered the normative variety of Asturian). The results obtained from this comparison will allow us to outline the differences between these three varieties in terms of object marking, shedding more light on the origin and function of Differential Object Marking in Spanish.

Recent developments in 3D sensors have raised the possibility of using them in an increasing number of engineering applications. However, since most 3D sensors, such as the laser range finder, are based on the use of light, which moves in straight lines, the measurement area is limited to the front of an object, making the back an ""invisible"" surface. To calculate such unmeasurable areas, a system that memorizes shapes often encountered in objects and superimposes them on the scene is required. To realize such a type of system, an appropriate 3D shape representation is needed. This representation should 1) be able to handle and compare partial and complete sets of data of object shapes, and 2) operate quickly enough to be applicable to real-time tasks. We developed a novel shape representation framework called ""Internal Radiated-light Projection (IRP)"" to represent and compare 3D objects. This representation projects local shape information of an object on a sphere by imaginary rays from the ""kernel"" of the object. To describe local shape information and arrange shapes properly, we propose Harmonic Contour Analysis (HCA) and the Shape Matrix. These concepts are characterized by 1) simplicity; 2) the use of local shapes and their adjacent information; and, by using the Shape Matrix, 3) the consideration of the effect of gravity and stable poses for objects. In IRP representation, we can categorize objects in known classes and calculate their positions and attitudes. This paper explains the basic concept behind IRP, which is a way of representing local 3D shapes by HCA and categorizing them using the Shape Matrix. We then present experiments in object recognition for both virtual and real objects to demonstrate its efficiency and feasibility.

Background: The environments that we live in impact on our ability to recognise objects, with recognition being facilitated when objects appear in expected locations (congruent) compared to unexpected locations (incongruent). However, these findings are based on experiments where the object is isolated from its environment. Moreover, it is not clear which components of the recognition process are impacted by the environment. In this experiment, we seek to examine the impact real world environments have on object recognition. Specifically, we will use mobile electroencephalography (mEEG) and augmented reality (AR) to investigate how the visual and semantic processing aspects of object recognition are changed by the environment. Methods: We will use AR to place congruent and incongruent virtual objects around indoor and outdoor environments. During the experiment a total of 34 participants will walk around the environments and find these objects while we record their eye movements and neural signals. We will perform two primary analyses. First, we will analyse the event-related potential (ERP) data using paired samples t-tests in the N300/400 time windows in an attempt to replicate congruency effects on the N300/400. Second, we will use representational similarity analysis (RSA) and computational models of vision and semantics to determine how visual and semantic processes are changed by congruency. Conclusions: Based on previous literature, we hypothesise that scene-object congruence would facilitate object recognition. For ERPs, we predict a congruency effect in the N300/N400, and for RSA we predict that higher level visual and semantic information will be represented earlier for congruent scenes than incongruent scenes. By collecting mEEG data while participants are exploring a real-world environment, we will be able to determine the impact of a natural context on object recognition, and the different processing stages of object recognition.

Three object-oriented analysis techniques: Shlaer & Mellor, Coad & Yourdon, and Document-Driven Analysis were evaluated. Criteria for comparison of analysis techniques were developed. These criteria state that an analysis technique should (1) cover data, transformation, and control perspectives of the problem, (2) address large problems through partitioning, bounding the problem, and supporting prototypes and incremental analysis, (3) provide approaches for verification and validation, and (4) support configuration control. A case study in a software engineering class was conducted using the three OOA techniques. Through the case study we found that (1) identifying objects is affected by notation and flexibility of object models, (2) visualizing global data, transformations, and control are necessary to capture end-user’s processes, (3) emphasizing hierarchical structures and third normal form divert the analyst’s attention from analysis to implementation, (4) an explicit representation of relationships is necessary, (5) peer review is useful in improving selection of objects and methods to support end-user processes, and (6) supporting a standard document from OOA products is not easy.

The multivariable PID neural network (MPIDNN) control system is introduced in this paper. MPIDNN is used to perform both the control and the decouple at the same time and to get better performance. It is difficult to control multivariable system by conventional controller because the strong coupling properties of the system. Generally, the decoupling system should be designed first and the multivariable object would be divided into several single variable objects. Then, several simple controller would achieve the control of those objects. The decoupling system and the controller exist in theory but the design process is very difficult actually because the transfer function of the object is difficult to get. Especially, if the number of the object inputs is not equal to that of the object outputs, which is called unsymmetry object, the conventional decoupling is impossible. A actual example is discussed in the paper in order to prove the function of the MPIDNN, in which an un-symmetry multivariable system which has 3 inputs and 2 outputs is controlled by a MPIDNN and the perfect control property is obtained by self-learning process.

Websites usually offer the same rating scale for all users and all tasks, but users can have very different preferences. In this paper, the authors study rating scales from the point of view of preferential choices, investigating i) if user preferences for rating scales depend on the object to evaluate, and ii) if user preferences change after they have rated an object repeatedly, gaining a high level of experience with the evaluated object. The authors first defined a model of rating scales, identifying generic classes based on features like granularity and visual metaphor. Then, the authors had users choose between three scales, one for each class, for rating two objects with opposite features, first in a condition where users had a low level of experience, and then in a condition where their level of experience was high. Results showed that user choices depend on the evaluated objects, while their level of experience influences their overall preferences, but not their choices when they have to rate a specific object. The authors conclude with some insights and guidelines for designers of interactive systems.

A characteristic feature of complex technical objects for special purposes is the presence in their composition of a large number (tens, hundreds of thousands) of various types component parts, which have different levels of reliability, different patterns of their wear and tear processes. This feature requires a more subtle approach to the organization and planning of maintenance in course of their operation. The problem is that in the development of such facilities, all issues related to maintainability and maintenance should be addressed already at the early stages of facility design. If you do not provide in advance the necessary hardware and software for the built-in monitoring of technical condition (TC) of the object, do not develop and "build" the maintenance technology into the object, then it will not be possible to realize in the future a possible gain in the reliability of the object due to maintenance. Since all these issues must be resolved at the stage of object creation (when the object does not yet exist), mathematical models of the maintenance process are needed, with the help of which it would be possible to calculate the possible gain in the level of reliability the facility due to maintenance, to estimate the cost costs required for this. Then, on the basis of such calculations, make a decision on the need for maintenance for this type of objects and, if such a decision is made, develop the structure of the maintenance system, choose the most acceptable maintenance strategy, and determine its optimal parameters. The article shows that the optimal parameters of various maintenance strategies significantly depend on both the reliability and cost structure of the facility and specified requirements for the facility's reliability . The higher the specified value , the more serviced items should be included in the optimal maintenance strategy. It has also been proven that the effectiveness of various maintenance strategies depends significantly on the reliability and cost structure of object. If the distribution of cost restored (including serviced) elements is closely correlated with the distribution of their reliability indicators, difference in effectiveness of different maintenance strategies is reduced. This is clearly seen in the example of Test-2 object, for which the least reliable elements are also the most expensive.

Target recognition from complex background is the emphasis and difficulty of computer vision, and rotary objects is widely used in the military and manufacturing field. Rotary object recognition in complex background based on improved BP neural network is proposed in the dissertation. Median filter is adopted to get rid of the noise and an improved method of maximum classes square error is used to compute the threshold of the image segmentation. The target recognition system based on improved BP neural network is established to recognize the rotary objects, and seven invariant moments of rotary objects serve as the input feature vector. The experiment results show that the image noise could be gotten rid of effectively and the image could be segmented exactly by the image preprocessing method put forward in the dissertation, and the seven invariant moments is appropriate for the character of rotary objects, and the rotary object recognition system based on BP neural network acquires an excellent recognition result.

Based on the perspective of cognitive linguistics, this paper probes into the metaphor cognition, metonymy cognition and both of them in the double-object constructions of English and Chinese, and points out that the double-object constructions in English and Chinese are similar in the above three aspects. However, there are also differences between English and Chinese double-object constructions, which are manifested in the following three aspects: the scope of double-object constructions, the conceptual patterns and the verbs that can enter the double-object constructions. By analyzing the similarities and differences between English and Chinese double-object constructions, it can be concluded that the syntactic structure of English and Chinese objects reflects the conceptual structures of human beings and the ways of cognition of the world, and even the sentence structure containing the same conceptual content will lead to the difference in meaning because of the different cognitive styles of events.

In production line, pose estimation of 3D object of products is needed beforehand. In order to perform shape measurement of the objects corresponding to speed of the mass production lines before the contact measurement is done, the information of object pose and matching is become required. In this paper, we conducted a study on the performance of model based and view based pose estimation method using image sequence of a rotating 3D object. In model based, we used object feature points from center of gravity and in view based method, the subspace calculation by block diagonalization of matrix represents a transformation an image to another image. We have confirmed the both method performance and it’s considered useful for pose estimation.

Parameters optimization design of high-speed moving object is a very complex question. It involves many other subjects both in theoretical research and engineering application. Therefore, it is very significant to research on motion parameter optimization design of high-speed moving object. Firstly, in the known initial moment, the entering depth of moving object is; the initial velocity is; the length of moving object is L; the angle into the water is; and the average relative density of object is. It researches on the optimization of the best slenderness ratio, cavitation number and cavitator radius of high-speed objects. And then it specifically deduces the best motion displacement under the known initial momentum. Finally, it takes computer simulation and imitation to all optimized parameters and gives specific numerical examples by applying MATLAB, which provides theoretical basis for actual experiments.

Objectives: To assess the effect of two of the most commonly used sterilization techniques on 3D printed clinical objects. Materials & Methods: The two sterilization methods used in our hospital and investigated in this paper are: Steam heat and Gas plasma. Three objects were printed and tested in this study: a tooth replica, an orthognathic final splint, a surgical cutting guide for the purpose of mandible reconstruction. For each of the 3 objects, 4 copies were made: one original STL object, one copy of the object pre-sterilization, one copy of post-steam heat sterilization, and one copy of post-gas plasma sterilization. Each printed object was scanned using a high resolution CBCT protocol and the compared (morphologically and volumetrically). Results: At the level of volumetric changes, no difference was found between pre and post-sterilization for both methods evaluated. As for the morphological changes, only differences were noticed with the orthognathic splint object indicating deformation of the printed splints after sterilization. Larger differences were observed with heat sterilization, making it less reliable. Conclusion: Sterilization of dental objects to be used in a clinical setting may lead to deformation of the printed model, especially for heat sterilization. Further investigations are needed to confirm these findings.

Photoelectron microscopy is as old as electron microscopy itself. Electrons liberated from the object surface by photons are utilized to form an image that is a map of the object's emissivity. This physical property is a function of many parameters, some depending on the physical features of the objects and others on the conditions of the instrument rendering the image.The electron-optical situation is tricky, since the lateral resolution increases with the electric field strength at the object's surface. This, in turn, leads to small distances between the electrodes, restricting the photon flux that should be high for the sake of resolution.The electron-optical development came to fruition in the sixties. Figure 1a shows a typical photoelectron image of a polycrystalline tantalum sample irradiated by the UV light of a high-pressure mercury lamp.

The human ventral temporal cortex (VTC) plays a critical role in object recognition. Although it is well established that visual experience shapes VTC object representations, the impact of semantic and contextual learning is unclear. In this study, we tracked changes in representations of novel visual objects that emerged after learning meaningful information about each object. Over multiple training sessions, participants learned to associate semantic features (e.g., “made of wood,” “floats”) and spatial contextual associations (e.g., “found in gardens”) with novel objects. fMRI was used to examine VTC activity for objects before and after learning. Multivariate pattern similarity analyses revealed that, after learning, VTC activity patterns carried information about the learned contextual associations of the objects, such that objects with contextual associations exhibited higher pattern similarity after learning. Furthermore, these learning-induced increases in pattern information about contextual associations were correlated with reductions in pattern information about the object's visual features. In a second experiment, we validated that these contextual effects translated to real-life objects. Our findings demonstrate that visual object representations in VTC are shaped by the knowledge we have about objects and show that object representations can flexibly adapt as a consequence of learning with the changes related to the specific kind of newly acquired information.

How does the brain translate an internal representation of an object into a decision about the object's category? Recent studies have uncovered the structure of object representations in inferior temporal cortex (IT) using multivariate pattern analysis methods. These studies have shown that representations of individual object exemplars in IT occupy distinct locations in a high-dimensional activation space, with object exemplar representations clustering into distinguishable regions based on category (e.g., animate vs. inanimate objects). In this study, we hypothesized that a representational boundary between category representations in this activation space also constitutes a decision boundary for categorization. We show that behavioral RTs for categorizing objects are well described by our activation space hypothesis. Interpreted in terms of classical and contemporary models of decision-making, our results suggest that the process of settling on an internal representation of a stimulus is itself partially constitutive of decision-making for object categorization.

HD 87643 is one of the B[e] stars that still defy our understanding to better classify it. The spectroscopic observations of HD 87643 performed in the Astronomical Observatory of La Silla (ESO) between December 1998 and April 2000 show an object far more complex than was already known, with profiles of the Balmer series showing variability on different time scales. This work examine the formation of Hα and Hβ profiles with the SEI method (Sobolev approximation with Exact Integration of the transfer equation), as well as their spectral energy distribution by means of codes Cloudy and Dusty. For a homogeneous and spherically symmetric nebula around a star with T ef ~ 15, 000 K and log L/L⊙ > 4.2, the reproduction of the profiles mentioned was only achieved for Hβ and to some extent, considering two distinct regions with different laws for the expansion of the wind and with different rates of mass loss.

In Classical Greek, many verbs take direct objects marked with genitive (GEN) or dative (DAT), rather than accusative (ACC) case. Traditional grammars (Smyth 1956, Boas et al. 2019) fail to offer principled descriptions or accounts of the distribution of ACC, GEN, DAT object case for transitive verbs. This paper analyzes a corpus involving case-assigning transitive verbs, and examines Luraghi’s 2010 Transitivity Hierarchy in this context. We find that, while her ranking of verbs’ transitivity is correct, the features used to determine the hierarchy are not. Our study demonstrates a highly significant correlation between a verb’s level of transitivity (as indicated by the case marking on its object) and the Proto-role Properties of Change of State and subject Volitionality (Dowty 1991).

In order to identify basic aspects in the process of tactile perception, we trained rats and humans in similar object localization tasks and compared the strategies used by the two species. We found that rats integrated temporally related sensory inputs (‘temporal inputs’) from early whisk cycles with spatially related inputs (‘spatial inputs’) to align their whiskers with the objects; their perceptual reports appeared to be based primarily on this spatial alignment. In a similar manner, human subjects also integrated temporal and spatial inputs, but relied mainly on temporal inputs for object localization. These results suggest that during tactile object localization, an iterative motor–sensory process gradually converges on a stable percept of object location in both species.

AbstractTasked with the mandate to “set the record straight” about the beginning of the liquid blackness research group and journal and to explicate the theoretical and conceptual parameters of the idea of black liquidity, this introduction negotiates the irreconcilable tension between keeping record and record keeping as a way to maintain the anaoriginarity of black study as an ensemblic and jurisgenerative practice. To do so, it draws inspiration from one of its objects of study, Larry Clark's 1977 cult film Passing Through, and specifically from the way the film's formal structure and historical existence as a withdrawing object mirror the elusiveness of the album that the musicians it depicts were never able to record. This introduction is divided into “tracks” to reproduce the same withdrawing effect, trigger a similar ensemblic gathering, and in the process, honor the object-oriented and immanent methodology developed by the liquid blackness project.
