Published: August 2018

Abstract
To improve the reliability of motor system, this paper investigates the sensor fault diagnosis methods for T-type inverter-fed dual three-phase permanent magnet synchronous motor (PMSM) drives. Generally, a T-type three-level inverter-fed dual three-phase motor drive utilizes four phase-current sensors, two direct current (DC)-link voltage sensors and one speed sensor. A series of diagnostic methods have been comprehensively proposed for the three types of sensor faults. Both the sudden error change and gradual error change of sensor faults are considered. Firstly, the diagnosis of speed sensor fault was achieved by monitoring the error between the rotating speed of stator flux and the value from speed sensor. Secondly, the large high-frequency voltage ripple of voltage difference between the estimated voltage and the reference voltage was used to identify the voltage sensor faults, and the faulty voltage sensor was determined according to the deviation of voltage difference. Thirdly, the abnormal current amplitude on harmonic subspace was adopted to identify the current sensor faults, and the faulty current sensor was located by distinguishing the current trajectory on harmonic subspace. The experiments have been taken on a laboratory prototype to verify the effectiveness of the proposed fault diagnosis schemes.

AbstractCommonly, an amazing and attractive advertisement intends to hypnotize their target consumer in seeing, reading, or even hearing the ads continually. Besides, the power of persuading and motivating in messages from the way of informing product benefit could also give impact to buyer in deciding to buy the product. This research discusses the contexts of advertising found on packages of two Nestle products, especially Nestle Dancow Actigo and Nestle Dancow Enrich. These products were analyzed based on pictures or symbols and text found on packages. It is aimed at finding out the context of discourse advertising on those packages. Data were collected from analysis of text, including pictures or symbols and additional questionnaires distributed to 50 respondents located at Denpasar and Gianyar. Urban society were used to evaluate concerning on their understanding of English even though Indonesian language mostly applied on packages of products. Method used in analyzing data is descriptive qualitative and quantitative with simple statistics and explanation. It showed that connotation and denotation meanings highlighted lexical items and its cultural adaptation using process of copy adaptation to fit the culture of their targeted consumers. Means found 6 words or phrases of English from 10 of them on packages understood by 50 respondents as of: 35 for Full Cream as highest score and 16 respondents for FortiGro as the lowest score. In addition, brand name, symbol and images showed producer seemed to have close relationship with consumer and able to attract target consumer attention as majority of findings. It can be concluded that ads on packages of Nestle Dancow had succeeded to be understood by the society through the messages implied.

AbstractThis article is focused on how the incident of G30S/PKI has left atrauma to the state and how the state deals with it in the era afterwards. It show that such incident is constructed by the state that PKI is the enemy of the state and threathens the sovereignity of the state ideology, and this is embedded to shape a collective memory. This has been used to construct and to normalize the anti-communist movement in Indonesia through various strategies by, for example, the establishment of Monumen Pancasila Sakti, the suppression of communist movement, the military recruitment, and a variety of doctrines in the military education. These aim to construct a united understanding about the incident of G30S/PKI and to normalize the anti-communist discourse in Indonesia.

Mana’ dan Éanan: Tongkonan, Harta Tongkonan, Harta Warisan, dan Kontribusi Ritual di Masyarakat Toraja
Authors: Idrus Nurul Ilmi 
Published: August 2018

Toraja shares traditions with other ethnic groups in South Sulawesi, but Toraja has its own uniqueness, primarily related to tongkonan, which is not only as physical manifestation—House (banua) and its ‘content’ (harta tongkonan), but it is also a venue for family gathering of the tongkonan members, a house-society and a source of property. This article is focused on inheritance system among Torajanese, it examines how individual property is inherited as well as how communal property is managed and benefitted by its members. Property, for Torajanese, compose of individual property (éanan) and communal property (mana’ tongkonan) which refers to property own by members of tongkonan from one pa’rapuang—ramage traced a first ancestor who founded a Tongkonan House. While individual property can be inherited to children, communal property cannot, it can only be maintained, managed, and benefitted from among members of tongkonan, though in practice there are some violation of such norms, and any violation is always associated with their ancestor. Since tongkonan is a source of property, this may also become a source of conflict among members of tongkonan, especially for prosperous tongkonan and in terms of who is eligible to manage tongkonan and its property (to ma’kampai tongkonan). A Torajanese may become a member of more than one tongkonan because of bilateral kinship system. But, since contribution towards tongkonan (maintenance and rituals) is costly and time-consuming, one should decide in which tongkonan he/she becomes the ‘core’ or the ‘common’ member. Despite the fact that the philosophy of inheritance sharing of individual property is mabbagé rata, various grounds may be taken into account which makes a difference between siblings in a nuclear family. I argue in this article that both the right to éanan and mana’ tongkonan are related to one’s contribution in different respect.
‘Butta Kodi, Biné Kodi’: Stigma dan Dampaknya Terhadap Tu Tamanang di Kabupaten Gowa
Authors: Syam Mirawati - , Idrus Nurul Ilmi 
Published: August 2018

Tu tamanang is a Makassar term for bad soil (butta kodi) for women and bad seed (biné kodi) for men, as sexual intercourse is analogised with planting (lamung-lamung). Whether or not one is considered as tu tamanang is not based on biomedical check-up, but simply on the basis ofmarital duration (5 years and more) and the attributes attached to tu tamanang which may be different by gender. The importance of the existence of children in the family has caused social stigma among tu tamanang. Such stigma is based on the attributes that can be observed, the gendered parable, the reproductive health-related perception towards the couple, and the label that tu tamanang are infortune persons. In dealing with such social stigma, tamanang women tend to be passive, while men are more aggressive, by showing their refusal to stigma through polygyny or divorce to get married. However, women also become agents in regard to divorce and polygyny. But, refusal towards social stigma is also the case for couple who does not problematised lack of children in the family, and tamanang is not simply a source of conflict. Stigma towards tu tamanang significantly affects the social life of tu tamanang, which is classified into 3 categories: self-isolation, demanding divorce and polygyny. There is a need to educate the society regarding the cause of infertility and how to deal with it, since existing various stigma against tu tamanang are based on social perception, which are non-medical and presumption. In addition, since biomedical service is not the main priority for tu tamanang, they need relevant information regarding existing service and service procedures because even though they access medical service, it has never been continued. This is because accessing medical service is identical with handling of various documents which they consider rather complicated.

The existence of Indonesia women through media has been pioneered by R.A Kartini who is known for hes ability in voicing his opinions and thoughts into her writing ability through letters. These letters in the present transformed into social media that became the medium of self-actualization of women. This Article focuses on how women educators in Makassar activity in the Facebook and Whatsapp. The study indicates that there are two main reasons why Facebook and Whatsapp are the preferred informative social media in this research, both of which are the most popular (because they are mostly used by one’s networking) and practical social media (because people can be easily found and to be found through these two social media and because of the facilities of these social media, they can share (like photos, documents, videos, etc.), and interact in various forms (such as video call, online games, etc.). Facebook and Whatsapp are used to connect each other, as the source of information, as an online shopping venue, a place hobby channeling, as well as a space to share moments. Their activities on Facebook and Whatsapp can be classified into silent readers, commentators, broadcasters, promoters, and owners of the stage. In fact, social media users are inversely proportional to the ability to understand Facebook and Whatsapp as ‘private spaces’ rather than as ‘public spaces’ where content are shared openly.
Memberships of the Open Cluster NGC 6405 Based on a Combined Method: Gaussian Mixture Model and Random Forest
Authors: Gao Xinhua 
Published: August 2018

AbstractThis paper presents a combined method of Gaussian mixture model and random forest to compute membership probabilities of stars by using large, high-dimensional data sets. A significant advantage of this method is that it allows us to easily identify likely cluster members in large data sets starting from small training samples. As a benchmark, we select 40318 stars in the field of the open cluster NGC 6405 from theGaiaData Release 2 (Gaia-DR2) by means of all five astrometric (positions, proper motions, and parallax) and photometric parameters. We use this combined method to determine likely cluster members in an eleven-dimensional parameter space. A total number of 518 high-probability (≥0.6) memberships are obtained, and the mean parallax and proper motion of the cluster are determined to be 2.171 ± 0.005 mas (461 ± 1 pc) and () = (−1.357 ± 0.023,−5.823 ± 0.020) mas yr−1, respectively. In addition, we quantitatively evaluate the relative importance of the parameters for membership determination and find that colors and magnitudes cannot be ignored in membership determination when using the RF method. Our results show that this combined method exhibits good performance in handling arbitrary high-dimensional and large data sets, such asGaia-DR2, and it can also be used to investigate other open clusters.
Young and Eccentric: The Quadruple System HD 86588

Published: August 2018

Abstract
High-resolution spectroscopy and speckle interferometry reveal the young star HD 86588 as a quadruple system with a three-tier hierarchy. The 0.″3 resolved binary A,B with an estimated period around 300 years contains the 8-yr pair Aa,Abc (also potentially resolvable), where Ab,Ac is a double-lined binary with equal components, for which we compute the spectroscopic orbit. Despite the short period of 2.4058 days, the orbit of Ab,Ac is eccentric (e = 0.086 ± 0.003). It has a large inclination, but there are no eclipses; only a 4.4 mmag light modulation apparently caused by star spots on the components of this binary is detected with Evryscope. Assuming a moderate extinction of A

V
= 0.5 mag and a parallax of 5.2 mas, we find that the stars are on or close to the main sequence (age >10 Myr) and their masses are from 1 to 1.3 solar. We measure the strength of the lithium line in the visual secondary B which, together with rotation, suggests that the system is younger than 150 Myr. This object is located behind the extension of the Chamaeleon I dark cloud (which explains extinction and interstellar sodium absorption), but apparently does not belong to it. We propose a scenario where the inner orbit has recently acquired its high eccentricity through dynamical interaction with the outer two components; it is now undergoing rapid tidal circularization on a timescale of ∼1 Myr. Alternatively, the eccentricity could be excited quasi-stationary by the outer component Aa.

Abstract
We present a multiwavelength study of the unassociated Fermi Large Area Telescope (LAT) source, 3FGL J0954.8−3948, which is likely the γ-ray counterpart of a 9.3 hr binary in the field. With more than 9 years of Pass 8 LAT data, we updated the γ-ray spectral properties and the LAT localization of the γ-ray source. While the binary lies outside the cataloged 95% error ellipse, the optimized LAT ellipse is 0.°1 closer and encloses the binary. The system is likely spectrally hard in X-rays (photon index

) with orbital modulations detected in optical, ultraviolet, and possibly X-rays. A steep spectrum radio counterpart (spectral index α ≈ −1.6) is also found in the TIFR GMRT Sky Survey, implying that it is a pulsar system. We obtained a series of SOAR and Gemini spectroscopic observations in 2017/2018, which show a low-mass secondary orbiting in a close circular orbit with K
2 = 272 ± 4 km s−1 under strong irradiation by the primary compact object. All the observations as well as the modeling of the X/γ-ray high-energy emission suggest that 3FGL J0954.8−3948 is a redback millisecond pulsar in a rotation-powered state.
Double Dipping: A New Relation between Stellar Rotation and Starspot Activity
Authors: Basri Gibor , Nguyen Hieu T. 
Published: August 2018

Abstract
We report the discovery of a new relationship between a simple morphological characteristic of light curves produced by starspots and stellar rotation periods. The characteristic we examine is whether the light curve exhibits one dip or two during a single rotation. We analyze thousands of Kepler light curves of main-sequence stars with temperatures from 3200 to 6200 K. Almost all the stars exhibit segments of their light curve that contain either single- or double-dip segments (very few have more than two significant dips per rotation). We define a variable, the “single/double ratio” (SDR) that expresses the ratio of the time spent in single mode to the time spent in double mode. Unexpectedly, there is a strong relationship between the SDR and the stellar rotation period, in the sense that longer periods come with a larger fraction of double segments. Even more unexpectedly, the slopes of the SDR–period relations are a clear function of stellar temperature. We also show that the relationships of spot variability amplitude (R
var) to rotation period have similar levels of scatter, slopes, and dependence on temperature as the SDR–period relations. Finally, the median R
var of single segments tends to be about twice that of double segments in a given light curve. We offer some tentative interpretations of these new results in terms of starspot coverage and lifetimes. It will be fruitful to look further into this novel “rotation–activity” relation, and better understand what information these aspects of the morphology of light curves bring to our knowledge of stellar magnetic activity.
The True Luminosities of Planetary Nebulae in M31's Bulge: Massive Central Stars from an Old Stellar Population
Authors: Davis Brian D. , Ciardullo Robin , Jacoby George H. , Feldmeier John. J. , Indahl Briana L. 
Published: August 2018

Abstract
We measure the Balmer decrements of 23 of the brightest planetary nebulae (PNe) in the inner bulge (r ≲ 3′) of M31 and deredden the bright end of the region’s [O iii] λ5007 PN luminosity function. We show that the most luminous PNe produce ≳1200 L
⊙ of power in their [O iii] λ5007 line, implying central star luminosities of at least ∼11,000 L
⊙. Even with the most recent accelerated-evolution post-AGB models, such luminosities require central star masses in excess of 0.66 M
⊙ and main-sequence progenitors of at least ∼2.5 M
⊙. Since M31's bulge has very few intermediate-age stars, we conclude that conventional single-star evolution cannot be responsible for these extremely luminous objects. We also present the circumstellar extinctions for the region’s bright PNe and demonstrate that the distribution is similar to that found for PNe in the Large Magellanic Cloud, with a median value of A
5007 = 0.71. Finally, we compare our results to extinction measurements made for PNe in the E6 elliptical NGC 4697 and the interacting lenticular NGC 5128. We show that such extinctions are not unusual and that the existence of very high-mass PN central stars is a general feature of old stellar populations. Our results suggest that single-star population synthesis models significantly underestimate the maximum luminosities and total integrated light of AGB stars.

Abstract
As part of a program to determine the dynamical masses of Cepheids, we have imaged the nearest and brightest Cepheid, Polaris, with the Hubble Space Telescope (HST) Wide Field Planetary Camera 2 and Wide Field Camera 3. Observations were obtained at three epochs between 2007 and 2014. In these images, as in HST frames obtained in 2005 and 2006, which we discussed in a 2008 paper, we resolve the close companion Polaris Ab from the Cepheid Polaris Aa. Because of the small separation and large magnitude difference between Polaris Aa and Ab, we used point-spread function deconvolution techniques to carry out astrometry of the binary. Based on these new measurements, we have updated the elements for the 29.59 year orbit. Adopting the distance to the system from the recent Gaia Data Release 2, we find a dynamical mass of 3.45 ± 0.75 M
⊙ for the Cepheid, although this is preliminary and will be improved by CHARA measurements covering periastron. As is the case for the recently determined dynamical mass for the Cepheid V1334 Cyg, the mass of Polaris is significantly lower than the “evolutionary mass” predicted by fitting to evolutionary tracks in the Hertzsprung–Russell diagram. We discuss several questions and implications raised by these measurements, including the pulsation mode, which instability-strip crossing the stars are in, and possible complications such as rotation, mass loss, and binary mergers. The distant third star in the system, Polaris B, appears to be older than the Cepheid, based on isochrone fitting. This may indicate that the Cepheid Polaris is relatively old and is the result of a binary merger, rather than being a young single star.
Repeated Imaging of Massive Black Hole Binary Orbits with Millimeter Interferometry: Measuring Black Hole Masses and the Hubble Constant
Authors: D’Orazio Daniel J. , Loeb Abraham 
Published: August 2018

Abstract
Very long baseline interferometry (VLBI) at millimeter (mm) wavelengths is being employed to resolve event horizon-scale structure of the environment surrounding the Milky Way black hole at an angular resolution of a few tens of microarcseconds. The same approach could also resolve the orbital separation of a population of massive black hole binaries (MBHBs). Modeling the inspiral of binaries due to gravitational-wave emission and gas and requiring binary orbital periods of less than 10 yr, we estimate that there may exist ∼100 resolvable MBHBs that are bright enough to be observed by mm-wavelength VLBI instruments over the entire sky at redshifts z ≲ 0.5. We propose to search for these resolvable MBHBs by identifying binaries with the required orbital separations from periodic quasar light curves identified in optical and near-IR surveys. These periodic-light-curve candidates can be followed up with radio observations to determine their promise for observation with VLBI at mm wavelengths. The VLBI observations over the timescale of a binary orbit can allow unprecedented precision in the measurement of the binary mass, to within 30%. In combination with an independent binary mass measurement, VLBI observation would allow a novel

measurement of the Hubble constant, independent from those currently proposed and employed.
