A STUDY OF THE PLASTICS COATINGS USED ON PLAIN SLIDEWAYS OF MACHINE TOOLS

In this paper, several types of plastics for facing machine tool slideways are described. They are the ones based on PTFE, epoxi and acetal resins. Tribological, mechanical and chemical properties of these coatings as well as their methods of application on plain slideways are described. The stick-slip motion which may occur on plain slideways is discussed. This article also presents an application of PTFE-Zerodur slideway for nanometric positioning system.
Using book dialogs to extract emotions from texts in Polish

Detection of emotions from text can be very challenging, especially if no annotated corpus is given. We propose to use book dialog lines and accompanying phrases to obtain utterances annotated with emotion vectors. We describe two different methods of achieving this goal. Then we use neural networks to train models that assign a vector representing emotions for each utterance. These solutions do not need any corpus of texts annotated explicitly with emotions, because information about emotions for training data is extracted from dialogs’ reporting clauses. We compare the performance of both solutions with other emotion detection algorithms.
HISTOLOGICAL STUDY OF CELERY AQUEOUS SEEDS EXTRACT ( APIUM GRAVEOLENS L . ) ON OVARIES IN ADULT FEMALE RATS

Most recent studies have focused on the use of herbal extracts in medicine and treatment of many diseases especially in the side of fertility be cause the containment of active compounds that play an important role in stimulating hormones responsible for fertility, one of the examples of these herbs is celery. For this reason, this study was designed to determine the importance of the aqueous extract of celery seeds in the increase of fertility of adult female rats through its reflection on the diameter of both ovary and uterus also the number of ovarian follicles. Thirty healthy adult female albino rats (2-3 month) aged with (130-170 gm) weight randomly divided into three groups: control group and two experimental groups, 10 rats for each group. The control group was given an equal amount of orally distilled water daily for 28 days while experimental group animals were given a single dose orally (0.057 g/kg per weight) and double dose (0.114 g/kg per weight) from celery seed aqueous extract also for 28 days. Five females randomly selected from each group for anesthesia and histology. After the sacrifice, the ovaries were removed from the body to be weighed and then prepared for the routine histological preparation stages to obtain colored microchips with a haematoxylineosin thickness of 5-7 micrometers ready for imaging and microscopic measurements. Results showed increased in the ovaries and uterus weights of female experimental groups that received celery extract as compared with control group. Microscopically sections of ovary were indicated noticeable increasing in the thickness of ovary and uterus muscle layer also increasing in the numbers of primary, secondary, Graafian Follicles and Corpora Lutea of both experimental rats that received single and double dose of celery extract as compared with control rats but not depended on the dose.
Non-linear sphere tracing for rendering deformed signed distance fields

Signed distance fields (SDFs) are a powerful implicit representation for modeling solids, volumes and surfaces. Their infinite resolution, controllable continuity and robust constructive solid geometry operations, coupled with smooth blending, enable powerful and intuitive sculpting tools for creating complex SDF models. SDF metric properties also admit efficient surface rendering with sphere tracing. Unfortunately, SDFs remain incompatible with many popular direct deformation techniques which re-position a surface via its explicit representation. Linear blend skinning used in character articulation, for example, directly displaces each vertex of a triangle mesh. To overcome this limitation, we propose a variant of sphere tracing for directly rendering deformed SDFs. We show that this problem reduces to integrating a non-linear ordinary differential equation. We propose an efficient numerical solution, with controllable error, which first automatically computes an initial value along each cast ray before walking conservatively along a curved ray in the undeformed space according to the signed distance. Importantly, our approach does not require knowledge, computation or even global existence of the inverse deformation, which allows us to readily apply many existing forward deformations. We demonstrate our method's effectiveness for interactive rendering of a variety of popular deformation techniques that were, to date, limited to explicit surfaces.
A Page Coherency Protocol for Popcorn Replicated-kernel Operating System

Popcorn is a Linux based replicated-kernel Operating System (OS). Popcorn was conceived as a research OS for a wide class of future heterogeneous-ISA hardware. Because of the novelty of such hardware, in which diverse OS-capable CPUs are glued together, it is not clear what level of memory sharing will be provided across these CPUs. In this paper we consider a setup in which diverse CPUs do not share memory. We addressed the problem of providing a coherent replicated process address space amongst different kernels, running on those CPUs, by proposing a new page coherency protocol. We deploy this protocol in Popcorn OS while adding additional functionalities to the Linux kernel to support inter-kernel thread migration and coordination. We tested and evaluated a prototype version of this work in an emulated environment; results show that the proposed page coherency protocol is effective and the implementation adheres to the model.
Hand Gesture Interface using Light-dark changes in an Illuminance meter built in mobile devices

This study examines a hand gesture interface using light-dark change in illuminance meters built in smartphones and tablets. A hand gesture is to be detected from a change in illuminance values obtained by an illuminance meter and classified through decision tree learning. This realizes intuitive operations by hand gestures on a mobile device. While many of studies on hand gesture recognition use camera images, it result in large computational complexity required for gesture recognition due to image analysis. Privacy consideration is also required. By using light-dark changes in an illuminance meter, hand gestures can be recognized with less computational complexity and lighter applications can be realized. It also does not require privacy consideration. The result of the precision verification experiment showed that 5 types of hand gestures were recognized at the average recognition rate of 95%. Generic applicability to unknown users and unknown light environments was also confirmed.
The Future of the Commons : Interfaces of Nature

The interfaces of nature and culture define the ultimate life support for human well-being. They constitute a common; they are fundamentally shared. The commons of nature-culture are places which make up everyday language and poetics through landscape metaphors and other common topoi. But the commons have many senses, not all of them commonsensical or commonplace. The adjective common describes something that is in joint use or possession; public, shared alike. In the early 2000s the related legal concept “Creative Commons” was formed to promote – often noncommercial – sharing of otherwise copyright-protected material. The interface of nature and culture is the shared life of ecosystems and creativity alike. This workshop proposes to think about the past and present as well as the Future of the Commons to investigate individual and collective life conditions and cultural production. Here is a field where nature and culture cross: ecological boundaries and ecosystem changes will inevitably affect our established ways of sharing and producing. The human nature is double: both zoon and bios, combining bare life and social life, nature and culture. How to care for forests, waters, landscapes, and cultural creativity – as individuals but also as members of a human collective? Academia and popular culture constantly produce cosmologies where nature and culture combine in either peaceful or hostile ways. Nearly a century ago Vladimir Vernadsky and Pierre Teilhard de Chardin (Cosmogenesis, 1922) described the sphere of human thought as the evolutionary “noosphere” alongside with the geosphere and the biosphere. In the 1970s, Lynn Margulis and James Lovelock’s Gaia hypothesis described the evolution of planetary life and ecology as a complex self-regulating global system. And now we talk about the global environmental changes introduced by the “anthropocene”; the present geological era that is for the first time marked by human dominance. The complex human-nature interactions form questions that do not fit traditional disciplinary boundaries. The Nature/Culture workshop The Future of the Commons cuts into an urgent research agenda, with a special interest in developing a platform for investigating these problems at the Centre for Baltic and East European Studies (CBEES).

MATERNAL MORTALITY TRENDS AND CORRELATES IN ZAMBIA

Globally, about 830 women die each day due to complications during pregnancy and childbirth [1]. In 2017 maternal associated causes were the fourth leading cause of death in Zambian women of childbearing age [2]. Zambia routinely reports maternal death occurrences and conducts investigations to determine causality. To understand trends in maternal deaths in Zambia, we performed a review of routinely reported maternal deaths using the 2018 Maternal Perinatal Death Surveillance Review. In 2018 Zambia reported 674 maternal deaths (MMR: 183 deaths per 100,000 live births). The primary causes of maternal deaths were obstetric hemorrhage and indirect causes. Obstetric hemorrhage was the most common cause of death among women ages 30-49 and women who had experienced more than one pregnancy, while indirect causes attributed to the most deaths among pregnant women ages 10-29 and first-time pregnant women. Despite committing to improve maternal health by endorsing the United Nations Sustainable Development Goals (SDG), Zambia is behind in achieving the third SDG of a maternal mortality ratio of less than 70 maternal deaths per 100,000 live births [3]. To actualize this goal, Zambia must continue comprehensive surveillance of maternal deaths as well as increase access to family planning services, quality antenatal care services, skilled birth attendants, and emergency obstetric care.

DeepLung: Smartphone Convolutional Neural Network-Based Inference of Lung Anomalies for Pulmonary Patients

DeepLung is an end-to-end deep learning based audio sensing and classification framework for lung anomaly (e.g. cough, wheeze) detection for pulmonary patients from streaming audio and inertial sensor data from a chest-held smartphone. We design and develop 1-D and 2-D convolutional neural networks for DeepLung, and train them using the Interspeech 2010 Paralinguistic Challenge features. Two different audio windowing schemes: i) real-time respiration cycle based natural windowing, and ii) static length windowing are compared and experimented with. Classifiers are developed considering 2 different system architectures: i) mobile-cloud hybrid architecture, and ii) mobile in-situ architecture. Patient privacy is preserved in the phone by filtering speech with a shallow classifier. To evaluate DeepLung, a novel and rigorous lung activity dataset is made by collecting audio and inertial sensor data from more than 131 real pulmonary patients and healthy subjects and annotated accurately by professional crowdsourcing. Experimental results show that the best combination of DeepLung convolutional neural network is 15-27% more accurate when compared to a stateof-the-art smartphone based body sound detection system, with a best F1 score of 98%.
Conceptualizing and operationalizing possibilities of values in connection with a Romanian-Hungarian comparative study

The aim of this study is to outline the theoretical framework of a Romanian-Hungarian comparative value examination taken among students. The starting point for us is defining the values, the process of their formation and outlining the possibilities of their research, as we must see how the values have been formed: in which fields they are embedded, with which fields they are in symbiosis and to which fields they are a response. While mapping these fields we will continue to consider the comparative dimension as a possible examination. As the empiricism of our research is provided by a student questioning, we pay separate attention to the role of formal institutions in the process of value formation. Familiarization with value systems that are different from the family and the clash of these spheres are outstanding factors in the formation of norms and individual thinking. It is especially true for the world of higher education, which, forming a mobility channel, may present the students with a completely different picture and thinking pattern from the one coming from home. In our analysis we pay special attention to the examination of certain dimensions of values relevant in our comparison – some of them are for instance the dimension of collectivismindividualism, the process of modernization and the role of cultural and religious factors. The study cannot touch upon the results of value sociological research concerning the two countries due to restrictions concerning the length and size of the study.
Speech recognition in reverberation and noise : the roles of the lexicon and age

Older adults tend to score worse in speech recognition (SR) tests compared to younger adults, even when their hearing is within the normal range [1,2]. Acoustically adverse conditions may exacerbate this difference [2, 3]. SR in acoustically adverse conditions is traditionally measured by SR tests that present speech signals masked by noise [2, 4, 5]. Reverberation has also been shown to constitute a (somewhat different) form of acoustic challenge [5, 6], although it is not quite clear how performance of older listeners with normal hearing (ONH) may be affected by this listening condition compared to younger listeners with normal hearing (YNH). Carroll et al. [7] found lexical access time and vocabulary size to predict speech-innoise recognition scores. Differences were shown for age group and for signal-to-noise ratios (SNR), indicating that the role of lexical access may depend on the acoustic condition as well as population. Here, we asked,
Aalborg Universitet Analysis and Design of Improved Weighted Average Current Control Strategy for LCL-Type Grid-Connected Inverters

The LCL grid-connected inverter has the ability to attenuate the high-frequency current harmonics. However, the inherent resonance of the LCL filter affects the system stability significantly. To damp the resonance effect, the dual-loop current control can be used to stabilize the system. The grid current plus capacitor current feedback system is widely used for its better transient response and high robustness against the grid impedance variations. While the weighted average current (WAC) feedback scheme is capable to provide a wider bandwidth at higher frequencies but show poor stability characteristics under weak grid scenarios. To overcome this shortcoming, the improved WAC damping method is proposed with an additional capacitor current feedback loop. In this paper, a systematic parameter design guideline for the optimal selection of the current loop PR controller and the additional capacitor current feedback coefficient are presented for the improved WAC feedback control strategy. The satisfactory range of the system control parameters can be obtained under different delay conditions to meet the system performance specifications. The improved WAC method enhances system robustness under weak grid scenarios, and the stability and robustness have been enhanced under control delay. Finally, the experimental results are presented to validate the effectiveness of the proposed improved WAC control strategy and the parameter design method.
Advanced in Differential Equations ON THE δ-PRIMITIVE AND BOUSSINESQ TYPE EQUATIONS

In this article we consider the Primitive Equations without horizontal viscosity but with a mild vertical viscosity added in the hydrostatic equation, as in [13] and [16], which are the so-called δ−Primitive Equations. We prove that the problem is well posed in the sense of Hadamard in a certain type of spaces. This means that we prove the finite in time existence, uniqueness and continuous dependence on data for appropriate solutions. The results given in the 3D periodic space, easily extend to dimension 2. We also consider a Boussinesq type of equations, meaning that the mild vertical viscosity present in the hydrostatic equation, is replaced by the time derivative of the vertical velocity. We prove the same type of results as for the δ−Primitive Equations; periodic boundary conditions are similarly considered.
The Production of Chinese Affricates /ts/ and /tsh/ by Native Urdu Speakers

Previous studies have shown that learners with different native language backgrounds have common difficulties in learning Chinese affricates but demonstrate in various patterns. While few studies investigated this issue of native Urdu speakers. To address the production of Chinese affricates /ts/ and /tsh/ by native Urdu speakers, speech materials, produced by two groups of subjects with different Chinese proficiency, were selected from the BLCU-SAIT speech corpus. The error rate and error types of their production of Chinese affricates /ts/ and /tsh/ have been discussed after transcription and data analysis. The results show that though there are no counterparts of Chinese affricates /ts/ and /tsh/ in Urdu, the error and the acquisition pattern of these two affricates, to some extent, affected by individual differences of their roles in Urdu except universal similarities and differences between two languages. The findings of this study shed some light on second language learning and teaching.
A diagrammatic language to build and share STEM teaching narratives

The design was based on four stages: 1) a very explicit design of the course, mainly on the dependence of the concepts, using Compendium, 2) the careful selection of icons for some key concepts, 3) the generation of short interrelated animations, which try to identify a suitable graphic language (with both formal syntax and semantics), 4) the proposal of metadata, some internal to each animation and other external, to interrelate them. The final export of this educational package would consist of animations and their metadata, which would help facilitate re-use, and embedding within other courses.
PROMINENCE MARKING IN KAZAN TATAR DECLARATIVES

This study reports on prominence marking in Kazan Tatar, a Turkic language spoken in Russia, in the framework of Autosegmental-Metrical phonology. The data are narrow and broad focus declaratives collected from eight native Tatar speakers. Analysis of broad focus declaratives confirmed the intonation model proposed earlier, i.e., stressed syllables (which is word-final) of sentence-medial words are marked by rising pitch accents, [L+H*] or [H*], while verbs are optionally marked with a high tone, [Hi], on their initial syllable. In narrow focus, focused words were produced with [L+H*], [Hi], or [Hi L+H*], with expanded pitch range. This suggests that the [Hi], which is not a pitch accent, marks prominence at the left edge of a word/phrase, similar to French initial accent. Words before and after the focused word were often deaccented or realized with a compressed pitch range. Furthermore, an IP-final [L%] truncation was observed when a sentence final verb was focused, ending with [L+H*] on the verb’s final syllable. But, the [L%] was fully realized when the IP-final syllable is extra-lengthened, creating a LHL contour.
Marine-terrestrial interaction of climate changes in West Equatorial Africa of the last 190 , 000 years

Palynological investigation of a marine piston core GeoB 1008-3 (6°35'S/10°19'E) from the highly productive area off the Congo fan provides a dinoflagellate cyst record reflecting marine surface water conditions during the last 190 ka and a pollen record of the vegetation changes in Central Africa induced by climatic fluctuations for the same period. The freshwater discharge of the Congo river is related to the intensity of the West African monsoon. During warmer and more humid phases, dinoflagellate cyst flux decreased in relation to lower productivity and increased freshwater input in the eastern South Atlantic. At the same time on the continent, the rain forest expanded. During the cooler interstadials of Stage 5, the Afromontane forest represented by Podocarpus pollen expanded to lower altitudes and occupied former areas of rain forest during periods showing intermediate levels for sea surface temperatures and river discharge. During the colder and more arid phases of glacial Stages 6 and 2, when freshwater run-off into the Gulf of Guinea decreased, dinoflagellate cysts were much more abundant. However, Stage 4 shows high levels of river discharge and a moderate dinoflagellate cyst flux coupled to low sea-surface temperatures of the eastern South Atlantic, while Stage 3 shows moderately high pollen percentages of the rain forest during phases with fluctuating fresh-water discharge and very low sea-surface temperatures. High sea levels at the beginning of the Last Interglacial and the Holocene favoured the expansion of mangroves.
INFLUENCE OF CONTENT VARIATIONS ON SMOOTHNESS OF NATIVE SPEAKERS’ REVERSE SHADOWING

Recently, a novel method of objective measurement of comprehensibility of L2 utterances was proposed. Native listeners were asked to shadow learners’ utterances, and from natives’ shadowings, 1) accuracy of shadowers’ articulation and 2) delay of shadowing were measured acoustically and automatically. These two measurements were found to be highly correlated with comprehensibility perceived by the shadowers. Comprehensibility, or smoothness of understanding is considered to be characterized well by the two measurements because shadowers have to listen, understand, and repeat simultaneously. This paper aims at validating this method from another viewpoint. Here, listeners are asked to shadow native utterances with varying levels of lexical, syntactic, semantic, and pragmatic complexity, which can easily influence perceived comprehensibility. Experiments show that the above two measurements depend strongly on the complexity levels. We can claim again that the two automatic measurements can characterize perceived comprehensibility well.
