How Ambiguous is the Structural Ambiguity

A word, phrase, or sentence is ambiguous if it has more than one meaning. The ambiguity, however, can be noticed if one really has a linguistic knowledge on how to analyze the phrase or sentence. Of the two kinds of ambiguity, lexical and structural, the latter is the one which is explored further in this paper. Structural ambiguity occurs when a phrase or sentence has more than one underlying structure. The phrase can be disambiguated by putting it in a sentence with some sort of formal signals which help the reader or hearer to recognize the sentence structure. Some of the signals include function words, inflections, affixes, stress, juncture, and punctuation. The rest of this paper discusses some types of structural ambiguity, how they differ, and some possible ways to resolve them

Physical and geometrical parameters of the binary system gliese 150.2

The speckle interferometric binary system Gl 150.2 (HIP17491) is analyzed using atmosphere modeling and dynamical analysis simultaneously. A synthetic spectral energy distribution (SED) for each of the two components of the system is built using Kurucz blanketed models. These SEDs are combined together to form the total flux, which is compared with the observed one in an iterative method to get the best fit. The parameters of the individual components which lead to the best fit are: T eff A = 5350 ± 50 K, T eff B = 4400 ± 50 K, log g A = 4.40 ± 0.05, log g B = 4.68 ± 0.05, R A = 0.95 ± 0.06R ⊙, R B = 0.58 ± 0.06R ⊙, and π = 38.63 ± 0.79 mas, as given by the modified Hipparcos measurement. A modified orbit of the system is introduced and compared with earlier orbits. Hence, the masses of the two components are derived from the coincidence between the atmosphere modeling and dynamical analysis. Based on the estimated physical and geometrical parameters of the system, which are confirmed by synthetic photometry, the spectral types and luminosity classes of the two components are found to be G9.5V and K7V for the primary and secondary stars respectively, with an age of about 8 Gyr. Finally, the positions of both components on the H-R diagram are plotted, and the formation and evolution of the system are discussed. © 2014 Pleiades Publishing, Ltd

YETI observations of the young transiting planet candidate CVSO 30 b

CVSO 30 is a unique young low-mass system, because, for the first time, a close-in transiting and a wide directly imaged planet candidates are found around a common host star. The inner companion, CVSO 30 b, is the first possible young transiting planet orbiting a previously known weak-lined T-Tauri star. With five telescopes of the 'Young Exoplanet Transit Initiative' (YETI) located in Asia, Europe and South America we monitored CVSO 30 over three years in a total of 144 nights and detected 33 fading events. In two more seasons we carried out follow-up observations with three telescopes. We can confirm that there is a change in the shape of the fading event between different observations and that the fading event even disappears and reappears. A total of 38 fading event light curves were simultaneously modelled. We derived the planetary, stellar, and geometrical properties of the system and found them slightly smaller but in agreement with the values from the discovery paper. The period of the fading event was found to be 1.36 s shorter and 100 times more precise than the previous published value. If CVSO 30 b would be a giant planet on a precessing orbit, which we cannot confirm, yet, the precession period may be shorter than previously thought. But if confirmed as a planet it would be the youngest transiting planet ever detected and will provide important constraints on planet formation and migration time-scales.Comment: 14 pages (20 with appendix), 7 figures (16 with appendix), 6 tables (7 with appendix

Balanced Scorecard Method as Measurement of Key Performance Indicators at PT PELNI (Persero)

PT PELNI (Persero) is engaged in sea transportation and strives to design a comprehensive performance measurement system. The purpose of the research was to identify the indicators used by PT PELNI (Persero) as a measurement of employee performance, draft the concept of a balanced scorecard system in accordance with the measurement of the company's performance, and develop a balanced scorecard simulation design in accordance with the vision, mission, and strategy of PT PELNI (Persero). Measuring the company's performance using the Balanced Scorecard (BSC) method begins with SWOT analysis. This analysis aims to determine internal factors and external factors of the company. From the results of this analysis will be known the current position of the company and what strategies should be applied. The results showed that the company is in good shape, but facing challenges, so the strategy to choose is a diversification strategy. The final result of this study is the selection of several KPIs and 7 (seven) work programs that must be done, including improved efficiency of asset use, promoting cheap tickets during the covid-19 pandemic, efficiency and control utilization during the covid-19 pandemic, developing agency applications and automation of travel service systems, to ensure and monitor On-Time Performance (OTP) per ship, voyage account application development, improving education and training programs for employee self-development
