Authors: Ieamsaard Jirarat , Yammen Suchart , Muneesawang Paisarn , Sandnes Frode Eika 
Published: April 2020

The Head Gimbal Assembly (HGA) is an essential hard disk drive (HDD) component allowing data to be read from and written to the media. Defects on the HGA may affect the data read/write process and reduce the quality of the HDD. Therefore, HGA inspection needs to be improved during HDD manufacturing. This paper describes an image processing method that automate the optical inspection of HGA solder jet ball joint defects. Vertical edge detection methods are proposed for identifying defects. The performance of the vertical edge detection method is compared to a Sobel-based method, Roberts’ method and a Prewitt’s method. The methods were tested with 18,123 HGA images. The experimental results show that the vertical edge detection method outperforms the other methods, which had an accuracy of 99.3%, as compared to the Sobel based method, with an accuracy of 80% and 78.2 for Roberts’ method and 65.9 for Prewitt’s method.

Published: April 2020

Sentiment analysis of food recipe comments is to identify user comments about the food recipes to the positive or the negative comments. The proposed method is suitable for analysing comments or opinions about food recipes by counting the polarity words on the food domain. The benefit of this research is to help users to choose the preferred recipes from different food recipes on online food communities. To analyse food recipes, the comments of each recipe from members of the community will be collected and classified to neutral, positive or negative comments. All recipes’ comment messages are processed using text analytics and the generated polarity lexicon. Therefore, the user can gain the information to make a smart decision. The evaluation of the comment analysis shows that the accuracy of neutral and positive comment classification is about 90%. In addition, the accuracy of negative comment identification is more than 70%.
Dynamic Codebook for Foreground Segmentation in a Video
Authors: Kusakunniran Worapan , Krungkaew Rawitas 
Published: April 2020

The foreground segmentation in a video is a way to extract changes in image sequences. It is a key task in an early stage of many applications in the computer vision area. The information of changes in the scene must be segmented before any further analysis could be taken place. However, it remains with difficulties caused by several real-world challenges such as cluttered backgrounds, changes of the illumination, shadows, and long-term scene changes. This paper proposes a novel method, namely a dynamic codebook (DCB), to address such challenges of the dynamic backgrounds. It relies on a dynamic modeling of the background scene. Initially, a codebook is constructed to represent the background information of each pixel over a period of time. Then, a dynamic boundary of the codebook will be made to support variations of the background. The revised codebook will always be adaptive to the new background's environments. This makes the foreground segmentation more robust to the changes of background scene. The proposed method has been evaluated by using the changedetection.net (CDnet) benchmark which is a well-known video dataset for testing change-detection algorithms. The experimental results and comprehensive comparisons have shown a very promising performance of the proposed method.
Output Voltage Control of the SP topology IPT system based on Primary side Controller operating at ZVS
Authors: Nutwong Supapong , Sangswang Anawach , Naetiladdanon Sumate , Mujjalinvimut Ekkachai 
Published: April 2020

This paper presents a technique to control the output voltage of a series-parallel (SP) topology inductive power transfer (IPT) system using only a controller, located on the primary side. This reduces the cost, size, complexity and loss of the system compared to conventional IPT dual-side controllers. An asymmetrical duty cycle control (ADC) of full-bridge inverters was used to control the DC output voltage to its designed value. Additionally, a zero voltage switching (ZVS) operation can be obtained at all power levels by varying the switching frequency of the inverter. Theoretical analysis was performed through a mutual inductance coupling model and verified by computer simulation. Experimental results of the circular magnetic structure IPT system with an adjustable air-gap confirm the validity of the proposed controller. The system efficiency was improved throughout the operation and the improvement became obvious as the output power was decreased.
A Decision Making Approach for Multi-Objective Optimization Considering A Trade-off Method
Authors: Sooktip Tipwimol , Wattanapongsakorn Naruemon 
Published: April 2020

In multi-objective optimization problem, a set of optimal solutions is obtained from an optimization algorithm. There are many trade-off optimal solutions. However, in practice, a decision maker or user only needs one or very few solutions for implementation. Moreover, these solutions are difficult to determine from a set of optimal solutions of complex system. Therefore, a trade-off method for multi-objective optimization is proposed for identifying the preferred solutions according to the decision maker’s preference. The preference is expressed by using the trade-off between any two objectives where the decision maker is willing to worsen in one objective value in order to gain improvement in the other objective value. The trade-off method is demonstrated by using well-known two-objective and three-objective benchmark problems. Furthermore, a system design problem with component allocation is also considered to illustrate the applicability of the proposed method. The results show that the trade-off method can be applied for solving practical problems to identify the final solution(s) and easy to use even when the decision maker lacks some knowledge or not an expert in the problem solving. The decision maker only gives his/her preference information. Then, the corresponding optimal solutions will be obtained, accordingly.
Very Short-Term Photovoltaic Power Forecasting Using Stochastic Factors
Authors: Khumma Kriangkamon , Tamee Kreangsak 
Published: April 2020

This paper proposes a photovoltaic (PV) power forecasting model, using the application of a Gaussian blur algorithm ﬁltering technique to estimate power output and the creation of a stochastic forecasting model. As a result, aﬀected power can be forecasted from stochastic factors with machine learning and an artiﬁcial neural network. This model focuses on very short-term forecasting over a ﬁve minute period. As it uses only endogenous data, no exogenous data is needed.
To evaluate the model, results were compared to the persistence model, which has good short-term forecasting accuracy. This proposed PV forecasting model gained higher accuracy than the persistence model using stochastic factors.
The Importance of Government Incentives for Automating Business Processes in Industry in Order to Increase the Efficiency of Innovation
Authors: Klimova N. P. 
Published: April 2020

To develop innovative activities, the state offers various options for assistance and support within the framework of the innovation stimulation system. However, many of the proposed support tools remain unclaimed, since it is often difficult for organizations to evaluate and calculate the effect of their use due to the insufficient development of information systems. The level of automation of accounting is insufficient for making quick and informed decisions, which reduces the competitiveness of organizations. The main drawback of the existing systems of automation of accounting and management in industrial organizations is their fragmentation, inflexibility, and inconsistency with modern requirements for complex information systems. Many organizations keep records in separate workstations, the so-called workstations, many calculations are carried out by means of table editors; the transition to integrated information systems has not yet become widespread. The starting point in the financial mechanism for stimulating innovation should be tools to stimulate the automation of business processes. The limiting factor for the transition to such systems is the high cost of implementation, therefore, the article considers the advantages and disadvantages of applying soft loans in order to stimulate further innovative development in this area, and also suggests expanding the practice of using such a promising tool to stimulate investment in business informatization as innovative vouchers on information technology. The advantages of such an instrument include the strengthening of the link between research, educational institutions and the real sector of the economy, and this tool also has such advantages as high transparency of spending and targeting. The relevance of the chosen research topic is also due to the fact that, according to the Concept of the National Strategy for Sustainable Development of the Republic of Belarus for the period until 2035, digitalization based on high technologies and new business models has been identified as a key element of the new model of the national economy [1].

Abstract
Rotationally modulated variability of brown dwarfs and giant planets provides unique information about their surface brightness inhomogeneities, atmospheric circulation, cloud evolution, vertical atmospheric structure, and rotational angular momentum. We report results from Hubble Space Telescope/Wide Field Camera 3 near-infrared time-series spectroscopic observations of three companions with masses in or near the planetary regime: VHS J125601.92–125723.9 b, GSC 6214–210 B, and ROXs 42 B b. VHS J1256–1257 b exhibits strong total intensity and spectral variability with a brightness difference of 19.3% between 1.1 and 1.7 μm over 8.5 hr and even higher variability at the 24.7% level at 1.27 μm. The light curve of VHS J1256–1257 b continues to rise at the end of the observing sequence so these values represent lower limits on the full variability amplitude at this epoch. This observed variability rivals (and may surpass) the most variable brown dwarf currently known, 2MASS J21392676+0220226. The implied rotation period of VHS J1256–1257 b is ≈21–24 hr assuming sinusoidal modulations, which is unusually long for substellar objects. No significant variability is evident in the light curves of GSC 6214–210 B (<1.2%) and ROXs 42 B b (<15.6%). With a spectral type of L7, an especially red spectrum, and a young age, VHS J1256–1257 b reinforces emerging patterns between high variability amplitude, low surface gravity, and evolutionary phase near the L/T transition.
WASP-4 Is Accelerating toward the Earth

Published: April 2020

Abstract
The orbital period of the hot Jupiter WASP-4b appears to be decreasing at a rate of −8.64 ± 1.26 ms yr−1, based on transit-timing measurements spanning 12 yr. Proposed explanations for the period change include tidal orbital decay, apsidal precession, and acceleration of the system along the line of sight. To investigate further, we performed new radial-velocity measurements and speckle imaging of WASP-4. The radial-velocity data show that the system is accelerating toward the Sun at a rate of −0.0422 ± 0.0028 m s−1 day−1. The associated Doppler effect should cause the apparent period to shrink at a rate of −5.94 ± 0.39 ms yr−1, comparable to the observed rate. Thus, the observed change in the transit period is mostly or entirely produced by the line-of-sight acceleration of the system. This acceleration is probably caused by a wide-orbiting companion of mass 10–300 M
Jup and orbital distance 10–100 au, based on the magnitude of the radial-velocity trend and the nondetection of any companion in the speckle images. We expect that the orbital periods of one out of three hot Jupiters will change at rates similar to WASP-4b, based on the hot-Jupiter companion statistics of Knutson et al. Continued radial-velocity monitoring of hot Jupiters is therefore essential to distinguish the effects of tidal orbital decay or apsidal precession from line-of-sight acceleration.
Se construire une identité de poète sur Twitter : polarisation et dynamiques
Authors: Cassina Adrien 
Published: April 2020

À l’instar de la littérature, la poésie est largement présente sur le Web, comme en témoignent les nombreux blogs, revues ou anthologies en ligne. Twitter a ainsi pleinement été investi par des poètes qui, à travers une pratique d’écriture et de diffusion de poésie, développent tant une activité artistique qu’une sociabilité numérique. Comment ces femmes et ces hommes utilisent-ils les ressources de la plateforme Twitter pour construire leur identité de poète ? L’analyse se concentrera sur les références visuelles, textuelles et procédurales utilisées par ces poètes qui, en puisant dans l’imaginaire littéraire et les représentations liées au Web, mettent en scène des présentations d’eux-mêmes et construisent, en se saisissant des possibilités offertes par la plateforme, leur identité numérique de poète.
Poïèse et Poèse : faire avec et faire contre les outils d’écriture
Authors: Candel Étienne 
Published: April 2020

Dans cet article, Étienne Candel interroge, de façon réflexive, la réception des textes qu’il a produits, notamment sur Twitter, Mastodon et Instagram, sous le nom d’ ironèmes et de trashtexts . Ces deux formats d’écriture inventés par lui sont des usages des dispositifs d’écriture en ligne et participent à ce titre de ce qu’il appelle la « poïèse » ; mais ils sont aussi des objets reçus socialement comme des formes littéraires, poétiques ou artistiques, et c’est ce phénomène d’artistisation qu’il décrit sous le nom de « poèse ». L’enjeu de l’article est d’envisager une articulation plus générale entre le « faire » de l’usage et les modalités qualifiantes des processus de réception.
Une poésie machinique ? Génération automatisée, intelligence artificielle et création littéraire
Authors: Lebrun Tom , Audet René 
Published: April 2020

Cet article porte sur la présence de poésie produite par des machines (générateurs, intelligence artificielle) sur les réseaux sociaux. Nous y interrogeons le deuxième degré de distance que les algorithmes parviennent à atteindre dans leur émulation du langage humain ; particulièrement, nous examinons comment l’informatique se mesure à une « communication » littéraire. Alors que des bots arrivent assez bien à générer ce que l’on reconnaît comme poésie, grâce à certaines stratégies d’authentification du discours, les algorithmes d’apprentissage machine exemplifient, par leur fonctionnement, la lecture mise en réseau et l’idée même de la mobilisation d’une culture partagée dans l’écriture littéraire.
DSDV Extension to Enhance the Performance of Ad Hoc Networks in High Diverse-Velocity Environments
Authors: Abdel Jawad Mada’ , Salah Saeed , Zaghal Raid 
Published: April 2020

<p class="0abstractCxSpFirst">Mobile Ad-Hoc Networks (MANETs) are characterized as decentralized control networks. The mobile nodes route and forward data based on their routing information without the need for routing devices. In this type of networks, nodes move in an unstructured environment where some nodes are still fixed, others are moving in a constant velocity, and others move with diverse velocities; and thus, they need special protocols to keep track of network changes and velocity changes among the nodes. Destination Sequenced Distance-Vector (DSDV) routing protocol is one of the most popular proactive routing protocols for wireless networks. This protocol has a good performance in general, but with high speed nodes and congested networks its performance degrades quickly.</p><p class="0abstractCxSpLast">In this paper we propose an extension to the DSDV (we call it Diverse-Velocity DSDV) to address this problem. The main idea is to modify the protocol to include node speed, determine update intervals and the duration of settling time. To evaluate the performance of the new protocol, we have carried a number of simulation scenarios using the Network Simulator tool (NS-3) and measured relevant parameters such as: packet delivery ratio, throughput, end-to-end delay, and routing overhead. We have compared our results with the original DSDV and some of its new variants. The new protocol has demonstrated a noticeable improvement of performance in all scenarios, and the measured performance metrics outperform the others except the average delay where the performance of the new protocol was modest.</p>
Le slogan de campagne entre effet de style et argumentation : les législatives ivoiriennes de 2016
Authors: Houessou Dorgelès 
Published: April 2020

À partir d’un corpus tiré des législatives ivoiriennes de 2016, cette étude explore la pratique du slogan en tant que modalité générique du discours électoral. D’un point de vue stylistique et rhétorique, elle examine la forme phonétique et rythmique des slogans liée à une praxis de configuration du sens qui est celle du discours symbolique iconique. Simultanément, elle lie ces aspects à l’argumentation dans le discours des slogans de campagne électorale en contexte ouest-africain, en tenant compte aussi bien de leur « visée » que de leur « dimension » argumentative (Amossy). Cette démarche se réalise à travers deux grandes étapes : analyse des aspects stylistiques des slogans (formes et figuralité, variantes diastratiques et diatopiques) ; étude de leurs stratégies argumentatives et de leur dimension éthotique, le tout conduisant à la formulation de réserves sur certaines occurrences contre-productives. Les slogans pris pour objet sont constamment rapportés à leur soubassement ethnoculturel à travers la notion d’« imaginaire » linguistique, ce qui permet de corréler le rhétorique avec la culture ivoirienne, tout en explorant sa dimension sociopolitique.
Efficacy and Safety of Ayurveda Interventions for Obesity
Authors: Rai Amit K , Kumari Harit , Ahmad Azeem , Kumar Sanjiv , Rao Bhogavalli Chandra Sekhara , Srikanth Narayanam 
Published: April 2020

Background:
Obesity is similar to Sthaulya or Medoroga described in Ayurvedic classical texts. Results from case studies/series and small clinical trials concluded that Ayurveda interventions have been effective in the management of obesity. This protocol aimed to do a systematic review of clinical studies related to Ayurvedic interventions in the management of obesity and further meta-analysis of eligible studies to generate the evidence regarding effectiveness and safety of Ayurvedic treatment modalities for obesity.

Materials and methods:
Clinical studies related to Ayurvedic interventions in the management of Sthaulya/Medoroga or overweight/obesity published in English/Hindi will be screened as per the inclusion criteria without restriction on publication date and type. Primary outcomes to be assessed will be improvement in clinical features of Sthaulya/Medoroga and change in body weight, body mass index (BMI), waist circumference, waist-hip ratio, and skin-fold thickness. Data will be extracted independently by two review authors on study characteristics (authorship, publication-related information, methodology, participants, interventions, comparators, outcomes, and results) in a prestructured format for assessment of study quality and data analysis. Two authors will independently assess the risk of bias in included studies. We will conduct metaanalyses only when the included studies will be sufficiently homogeneous in terms of design, study population characteristics, interventions, and outcome measures. If meta-analyses will not be conducive, we will summarize the results of included studies as systematic qualitative synthesis.

Conclusion:
The results generated from this review will be helpful in identifying the status of evidence for Ayurvedic interventions in management of obesity. It will also provide way for future research to generate stronger evidence regarding efficacy of Ayurvedic interventions in the treatment of obesity.

Clinical significance:
The study will be able to generate evidence for effective implementation of Ayurvedic interventions in treatment and prevention strategies for obesity.
