Finite Size Effect of One-dimensional Thermal Radiation
김희태,윤석주,유순재 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.56 No.2
The size effect of one-dimensional thermal radiation is investigated as a function of length and temperature. When the length of the body becomes small, the maximum wavelength of the thermal radiation is on the order of the size, so the spectrum of the thermal radiation becomes different from that of one-dimensional blackbody radiation. We calculate the energy density by considering the dimension of the length. The thermal radiation can be approximated by Wien’s law in highfrequency range when the size becomes small. The energy density is shown to be a function of length at constant temperature. The energy density is also shown to be a function of temperature at constant length.
Temperature Measurement Techniques for RAON Cryomodule
김희태 한국진공학회 2018 Applied Science and Convergence Technology Vol.27 No.2
Conducting and semiconducting temperature sensors are calibrated and applied to cryomodules. The definition of temperature is introduced and the pressure in vacuum is shown as a function of temperature. The resistance of Drude model is shown as a function of carrier density and mean free path. Temperature sensors are calibrated with Physical Property Measurement System (PPMS). The temperature sensors are applied to measure temperature accurately in RAON cryomodules.
Detection of Pressure Waves in Water by Using Optical Techniques
김희태,유순재,조신호 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.4
The change in the transmision of light going through a liquid is expresed as a change in the presure in the liquid and the presure wave in the water is detected by measuring that change in the transmision of light. A piezo transducer is instaled on the botom of the water container to generate presure wave. The presure wave in the water is detected using a photodiode aligned with a laser beam going through the liquid. The photodiode detects intensity oscilations in the transmision light. Those oscilations are caused by a change in the refractive index due to density oscilations from the presure wave in the water. The oscilation amplitude of the detected light intensity increases linearly with the presure of the wave.
A Principled Explanation on the Quantifier Scope Phenomena
김희태 언어과학회 2018 언어과학연구 Vol.0 No.87
The purpose of this study is to present a principled explanatory alternative mechanism for the scope puzzling phenomena in the quantifier constructions. For this, Multiple Agree (Chomsky 2001; Hiraiwa 2000), Phase (Chomsky 1998, 1999), Phase higher evaluation (Chomsky 1999), Feature-inheritance from Phase (Chomsky 2005, 2013, 2014), INT (Chomsky 1999, 2001) and semantic Duality of the Interface (Boeckx 2008; Chomsky 2005; Grohmann 2003; Kim 2018) are adopted. In addition, [±D]-feature is posited on the basis of the interpretation of θ–domain. By using this system, the DOC construction, the counterexample to Hornstein’s (1995, 1999) A-movement for Case-checking account, the counterexample to Fox’s (1995, 2000) Scope Economy account, and the bi-clausal quantifier sentence are solved. Not only that, the c-command and Fox’s (2000) Revised Modularity Hypothesis are also explained in a natural manner. (Keimyung University)
