Study of the influence of the structure of rolled iron on its hardness

Problem. The influence of the structure of cast irons on their hardness was studied using multifractal analysis. The spectrum of statistical dimensions of the cast iron microstructure was calculated using the Renyi formula. Materials and methods. The hardness of chromium-nickel cast iron was determined at three points of the sample. Results of experiments. It was found that the pairwise correlation coefficients for predicting hardness by traditional structure characteristics (length, diameter, area) were R2 = 0.73. 0.87. When assessing hardness indicators by multifractal characteristics, the correlation coefficients are 0.78. 0.88 for the pearlite structure with flake graphite and 0.81. 0.93 for the pearlite structure with spherical graphite. The sensitivity coefficients of the hardness indicators of СПХН-43 rolls to the information and correlation dimensions of carbides, as well as to the fractal and statistical D-100 dimensions of flake graphite were determined. The sensitivity of hardness indicators to the fractal and statistical D100 dimensions of carbides and to the fractal and correlation dimensions of flake graphite was determined for СПХНФ-47 rolls. Conclusions. Based on the results obtained, an approach to assessing the hardness of СПХН-43 and СПХНФ-47 rolls was developed, which includes: 1). Determination of the statistical dimension spectrum of the cast iron structure elements. 2). Determination of the sensitivity coefficients of hardness indicators to the spectrum of dimensions of structural elements. 3). Creation of a mathematical model for predicting the hardness of rolls. The considered approach can be interpreted as an alternative method for assessing the quality criteria of cast irons based on the analysis of their structure.
GloTSFormer: Global Video Text Spotting Transformer

Video Text Spotting (VTS) is a fundamental visual task that aims to predict the trajectories and content of texts in a video. Previous works usually conduct local associations and apply IoU-based distance and complex post-processing procedures to boost performance, ignoring the abundant temporal information and the morphological characteristics in VTS. In this paper, we propose a novel Global Video Text Spotting Transformer GloTSFormer to model the tracking problem as global associations and utilize the Gaussian Wasserstein distance to guide the morphological correlation between frames. Our main contributions can be summarized as three folds. 1). We propose a Transformer-based global tracking method GloTSFormer for VTS and associate multiple frames simultaneously. 2). We introduce a Wasserstein distance-based method to conduct positional associations between frames. 3). We conduct extensive experiments on public datasets. On the ICDAR2015 video dataset, GloTSFormer achieves 56.0 MOTA with 4.6 absolute improvement compared with the previous SOTA method and outperforms the previous Transformer-based method by a significant 8.3 MOTA.

Optimal Buffer Management Policies for Delay Tolerant Networks

Delay Tolerant Networks are wireless networks where disconnections may occur frequently due to propagation phenomena, node mobility, and power outages. Propagation delays may also be long due to the operational environment (e.g. deep space, underwater). In order to achieve data delivery in such challenging networking environments, researchers have proposed the use of store-carry-and-forward protocols: there, a node may store a message in its buffer and carry it along for long periods of time, until an appropriate forwarding opportunity arises. Additionally, multiple message replicas are often propagated to increase delivery probability. This combination of long-term storage and replication imposes a high storage overhead on untethered nodes (e.g. handhelds). Thus, efficient buffer management policies are necessary to decide which messages should be discarded, when node buffers are operated close to their capacity. In this paper, we propose efficient buffer management policies for delay tolerant networks. We show that traditional buffer management policies like drop-tail or drop-front fail to consider all relevant information in this context and are, thus, sub-optimal. Using the theory of encounter-based message dissemination, we propose an optimal buffer management policy based on global knowledge about the network. Our policy can be tuned either to minimize the average delivery delay or to maximize the average delivery rate. Finally, we introduce a distributed algorithm that uses statistical learning to approximate the global knowledge required by the the optimal algorithm, in practice. Using simulations based on a synthetic mobility model and real mobility traces, we show that our buffer management policy based on statistical learning successfully approximates the performance of the optimal policy in all considered scenarios. At the same time, our policy outperforms existing ones in terms of both average delivery rate and delivery delay.
Psychological Fidelity: Perception of Risk

High-fidelity driving simulators provide a realistic and compelling experience for research participants. However, the credibility of research results from simulator studies continues to be challenged. The fidelity of the driving experience appears insufficient to overcome criticisms concerning the lack of psychological fidelity, defined as the extent to which the risks and rewards of participation in the experiment correspond to real-world risks and rewards. Experimental studies eliminate the injury risk associated with driving. They also typically eliminate the trip purpose, which influences all components of real-world driving. Unfortunately, researchers typically give little consideration to this problem, often instructing participants to drive as they normally would. In the absence of a well-defined driving context, such instructions can be confusing to some participants. Well-designed driving simulator experiments eliminate confusion about driving motives by creating constrained situations to elicit specific behaviors. Researchers must identify the driving components that have been eliminated by the simulation and attempt to replace them through the use of instructions and performance incentives. Instructions define the performance space and driving task components; incentives define the relative priorities associated with the task components. The effects of incentives on performance are determined by some combination of (1) the nature of the incentive; (2) task characteristics; (3) aspects of performance selected for measurement; and (4) individual differences. Incentives are likely to improve certain aspects of performance, while degrading others at the same time, implying that care must be taken in matching incentives to performance measures. Reward/penalty schemes are used to incorporate performance incentives into driving simulator studies. Practical issues associated with their use include: simulating the effects of significant negative outcomes (i.e., crashes); multiple crashes; effects of incentives over time; assessment of reward/penalty systems; and non-independence of performance measures. Detailed examples of the use of reward/penalty systems are presented. Problems of psychological fidelity apply to all platforms. Improving psychological fidelity eliminates unwanted variability due to individual differences in driving, which result from uncertainty about the experimenter’s priorities.
Opportunities of synergistically adjusting voltage-frequency levels of cores and DRAMs in CMPs with 3d-stacked DRAMs for efficient thermal control

Chip-Multiprocessors (CMPs) with 3D-stacked DRAMs is promising for solving the memory wall problem, but the high power density makes 3D ICs frequently operate at or near the thermal limit. System hot spot of a CMP with 3Dstacked DRAMs is usually in DRAMs that are in the layers farthest from the heat sink. Heat from DRAMs and cores are all accumulated in DRAMs. Therefore, existing thermal managements for 3D ICs all perform thermal control on cores only because lowering the power-level of cores can also lower DRAM access frequency. However, as the power consumption of single DRAM access increases with the number of DRAM stacks and the width of the vertical links, the instantaneous DRAM accesses may easily overheat the system. So, in addition to lowering the access frequency of DRAMs, reducing the power consumption per DRAM access is also crucial. In this paper, we characterize the thermal and performance behavior of the target architecture when the voltage and frequency levels of cores and DRAMs are synergistically controlled. We also evaluate the thermal and performance behavior of existing thermal control methods that can be applied to the target architecture. The insights provided by the characterizations presented in this paper are important for developing an effective thermal management policy for CMPs with 3D-stacked DRAMs. Our results show that, synergistically controlling the voltage-frequency levels of cores and DRAMs does achieve higher thermal efficiency than controlling cores only.

East African Seaports: an Application of the Concept of 'Anyport'

first century A.D., when the writer of the Periplus of the Erythraean Sea1 visited Mombasa and described trading stations along the coast to which Arab traders from the northern shores of the Indian Ocean brought wheat, sugar, cotton and china in exchange for slaves and ivory, rhinoceros horn, tortoiseshell and cinnamon. Early trading activity was based upon the seasonal reversal of winds in the Indian Ocean and upon the use of Arab sailing dhows; and because only the most rudimentary port facilities were needed, there existed a large degree of flexibility in terms of port sites. No fundamental change took place in this trade pattern until the nineteenth century when several factors combined to produce an acceleration and a reorientation of trade. In the earlier years of the century, African traders were moving increasingly to the coast, and Arabs penetrating farther inland from their base at Zanzibar; later European exploration and administration presented new necessities and opportunities for trade. Thus, the coastlands which for centuries past had been, in trading terms, nothing more than the western shore of the Indian Ocean,2 on the outer fringes of maritime circulations, became the maritime faqade of a developing region of considerable economic potential. This new orientation involved a crystallization of the formerly fluid pattern of port sites, as rail links were built inland and investment in port facilities grew, and the coming of the age of steam navigation also made possible the utilization of harbours hitherto neglected by the dhows. Five ports handling ocean-going vessels have emerged during the past 75 years to serve the needs of East Africa today: Mombasa, Tanga, Zanzibar, Dar es Salaam and Mtwara (Fig. I). Although there are important variations between the five seaports in terms of situation and site conditions, and in terms of facilities and traffic levels, they have shared many common features during their modem growth. This paper is concerned with the analysis of the development of these terminals within the framework of the 'Anyport' technique. The situation of the East African port group as a whole is generally advantageous, and site conditions at individual terminals do not present any insuperable obstacles to physical expansion, in the context of the functional framework within which each port now operates and is likely to continue to operate in the foreseeable future. The conditions of land and water situation which now favour the growth of the seaports have largely arisen during the last Ioo years; developments on both the landward and seaward sides, in transport and in economic and political geography, have now intensified and enormously widened the significance and relationships of the seaports, so that they no longer lie in a backwater but maintain links with major seaports in all the inhabited continents. The East African coast is equipped with several good natural harbours, where adequate shelter and deep water close inshore remove that dependence upon tidal fluctuations which so rigidly restricts shipping manceuvres in many
John Dewey and the Decline of American Education (review)

Henry T. Edmondson’s John Dewey and the Decline of American Education is a bold indictment of one of the fathers of modern educational thought and practice. Throughout this terse treatise, Edmondson places the blame for nearly every problem he perceives in today’s schools on John Dewey. Edmondson believes that problems such as low literacy rates, teacher burnout, and the loss of traditional values in education can be linked to John Dewey’s influence over schools in the United States. Edmondson refutes Dewey’s conceptions of religion, education, and democracy in his attempt to illustrate that education has been in decline for the last fifty years because of Dewey’s influence. Edmondson attempts to lead students and teachers toward his goal of “disinheriting Dewey. ” While Edmondson targets Dewey, a critical reading of this book reveals that Edmondson’s argument is another conservative attack on education in the United States. Edmondson’s critique of Dewey is in the vein of conservative scholars such as Allan Bloom and Diane Ravitch, who have voiced similar concerns regarding the loss of tradition in education. It is clear that Edmondson also believes that education can regain prominence only by abandoning Deweyan progressivism and embracing traditional Western values. Edmondson chooses to begin his critique of John Dewey by condemning Dewey’s rejection of organized religion. Edmondson asserts that Dewey, who was in fact a practicing Christian until his mid-thirties, wrongfully eschewed the mythology and ritualism of dogmatic religious practices such as Christianity. Edmondson argues that Dewey’s enmity toward organized religion has been absorbed in American education and states, “Nowhere has genuine faith been more scorned,
An event‐related potential study of retroactive interference in memory

NEURAL activity associated with overcoming retroactive interference in episodic memory was investigated with event-related brain potentials (ERPs). ERPs were recorded during a combined recognition/associative recall memory test in which subjects were required to identify previous studied words and recall their study associates. A retroactive interference condition (A–B, A–C, A–? ) was compared with two control conditions A–B, C–D, A–? and A–B, A–B, A–? ). No ERP effect specific to the interference condition was identified. ERPs to all three classes of old word differed however from those to new words. These differences involved two effects, one with a left parietal maximum that has been described before, and a left frontal effect of earlier onset which has not been reported previously. This latter effect may indicate a role for the left prefrontal cortex in associative retrieval.
‘What happens when you intuit?’: Understanding human resource practitioners’ subjective experience of intuition through a novel linguistic method

The objective of this research was to understand the phenomenon of intuition from the perspective of the intuitor. Against a background of a steadily growing interest in intuition in managerial decision research, and inclining towards a phenomenological stance, the research used a novel linguistic method based on ‘de-nominalization’ to access participants’ (124 human resource practitioners) experiences of intuition. Based on an analysis of responses to the question ‘What happens when you intuit? ’, the article: defines intuition based on participants’ subjective experiences; reveals the subjective experience of intuition as comprising three phases − ‘intuiting’, ‘intuition’ and ‘implementing’; uncovers two aspects of intuitive affect − ‘bodily awareness’ and ‘cognitive awareness’; and establishes that participants use primary metaphors to articulate their experiences of intuition. The article outlines the theoretical implications and practical relevance of these findings, and makes suggestions for further qualitative phenomenological studies of intuition.
