While there is a high degree of convergence in linguistics in the treatment of the progressive as an aspect, the English progressive is unusually wide in its range of uses. This paper highlights the distinction between aspectual and non-aspectual progressives. The primary function of the progressive is to present a situation as ongoing, and this strictly aspectual use of the progressive is referred to as 'aspectual progressive'. On the other hand, the uses of the English progressive that are not, in a strict sense, aspectual is called 'non-aspectual progressive'. There are at least three basic uses of non-aspectual progressives. The first is the so-called progressive futurate (e.g., John is leaving tomorrow). In English, the present progressive can be used to express future time reference. This use of the progressive is regarded as a non-aspectual one, on the grounds that its meaning cannot be accounted for in terms of ongoingness. The second use is the habitual progressive (e.g., She's smoking a lot these days). Given that the habitual is an aspect, it is natural that the habitual progressive is not an aspectual progressive because one cannot view a situation in two different ways. In addition, ongoingness is not a defining property of the habitual progressive but is only a contingent or subsidiary property. The real essence of the habitual progressive is habituality. The third use of non-aspectual progressives is the experiential or interpretative progressive (e.g., You're imagining things), whose main characteristic is the subjectivity of the speaker's interpretation. The experiential or interpretative progressive does not serve a primarily aspectual function because the meaning of ongoingness has nothing to do with the content of the utterance.

It is very important to measure and visualize the changes in the physical properties of fluid flow because this is the foundation of measurement techniques used in aerodynamics, heat transfer, plasma diagnostics, and stress analysis of transparent models. The optical methods are advantageous over probe-based techniques in the optical methods are of high speed, non-contact and are capable of providing full-field results with high spatial resolution. Therefore we propose the electronic speckle pattern interferometry(ESPI) that gives us a solution to overcome those limitations. In this paper the experimental results show qualitative and quantitative visualization of changes in the physical properties of the candle and alcohol lamp with 3D plotting. And we obtained the refractive index, mass density and temperature distribution of fluids. The results clearly show the process of flow phenomena and give the feasibility of quantitative interpretation of gasdynamics.

Near Infrared spectroscopy (NIR) used on human skin measurement was explored in the past decade. Many publications in different journals and magazines discussed the feasibility of the NIR technique for cosmetic product property studies. Based upon the results of pioneers, we have pursued some work of the NIR instrument coupled with a probe module for skin measurement in vivo and vitro. In part I of this paper, the specific Near Infrared spectroscopy instrument stability, human subject conditions and other parameters, which could affect the measurements reproducibility are discussed. Second derivative NIR spectra and Principle Components Analysis (PCA) are utilised for data interpretation. In part II of this paper, the relationship of human skin moisture and ageing, the gender information and finally, the discovery of penetration depth of NIR incident light on skin are reported. A theoretical penetration depth calculation equation is proposed. In part III, the study results of a couple of commercial skin care products effect will be described. The skin lotions were applied on human skin (in vivo) in order to exam the NIR feasibility to monitor the changes of moisture level. The results are consistently positive. From our primary study, it can conclude that the NIR is potentially a very powerful instrument for skin condition diagnostics, either for cosmetic and/or for medication purposes.

Oil-paper insulation of valve-side windings in converter transformers withstand electrical stresses combining with AC, DC and strong harmonic components. This paper presents the physical mechanisms and experimental researches on partial discharge (PD) of oil-paper insulation at pulsating DC voltage. Theoretical analysis showed that the phase-resolved distributions of PDs generated from different insulated models varied as the increase of the applied voltages following a certain rule. Four artificial insulation defect models were designed to generate PD signals at pulsating DC voltages. Theoretical statements and experimental results show that the PD pulses first appear at the maximum value of the applied pulsating DC voltage, and the resolved PD phase distribution became wider as the applied voltage increased. The PD phase-resolved distributions generated from the different discharge models are also different in the phase-resolved distributions and development progress. It implies that the theoretical analysis is suitable for interpretation of PD at pulsating DC voltage.

현대디자인의 변모에 가장 커다란 변화를 예고하고 전개하는 것이 바로 정보혁명에 기초한 멀티미디어의 등장이라 할 수 있다. 본 논문에서는 현금(現今)의 뉴미디어로서 디지털의 개념과 특성을 구체적으로 살펴보기 위해 변화된 환경에서 새로운 디자인 모델의 창출방법을 비교 분석하고 정보양식에 근거한 커뮤니케이션의 변화를 조망하고자 하였으며 디지털과 아날로그 속성의 비교분석과 디지털 개념과 특성을 구체화하기 위하여 디지털 미디어의 가장 커다란 특성이길 할 수 있는 ‘가상성(virtual reality)’과 ‘상호작용성(interaction)’에 대한 이론적 근거를 도출하였다. 따라서 본 논문에서는 위에서 언급된 문제점을 바탕으로 디지털디자인에서 나타나는 시공간구조의 새로운 해석방법으로 본 연구의 타당성을 입증하고자 하였다.

시간 영역과 주파수 영역을 사이의 공간을 뜻하는 부분 푸리에 영역으로 (fractional Fourier domains) 선형 시간-주파수 분포의 옮김 불변 특성을 일반화한다. 다른 선형 사주파수 분포와 달리 짧은 시간 푸리에 변환은(short time Fourier transform: STFT) 부분 푸리에 영역에서 크기 (magnitude-wise) 옮김 불변을 지니는데, 이 짧은 시간 푸리에 변환을 쓰면 분포를 좀더 쉽게 해석할 수 있다. 특히, 부분 푸리에 영역에서 크기 옮김 불변인 선형 분포는 짧은 시간 푸리에 변환뿐이라는 것을 밝힌다.

New procedure for evaluation of creep reduction factor using performance limit strain concept was introduced and confirmed through the creep test results. To determine the performance limit strain of the textile geogrid used in this study, the Sherby-Dorm Plots were applied and the results were compared with the results that applied existed limit strain criteria (GRI test method GG-4). The limit creep strain of the geogrid samples that determined by using the Sherby-Dorm Plots were all 11%. This value is more higher than the existed criteria as 10%. From this 11% limit strain the creep reduction factors were calculated at 100,000 hours design. It was resulted in 1.45 for all of the geogrid samples(8t/m, 10t/m). Finally, when it was compared with the creep reduction factors that using 10% criteria, there were some decrease of reduction factor values about $0.06{\sim}0.14$.

A series of Brazilian tests under diameter compression for disc specimens was carried out to investigate the strength and failure behavior by using acoustic emission (AE) and photography monitoring technique. On the basis of experimental results, load-displacement curves, AE counts, real-time crack evolution process, failure modes and strength property of granite specimens containing two pre-existing holes were analyzed in detail. Two typical types of load-displacement curves are identified, i.e., sudden instability (type I) and progressive failure (type II). In accordance with the two types of load-displacement curves, the AE events also have different responses. The present experiments on disc specimens containing two pre-existing holes under Brazilian test reveal four distinct failure modes, including diametrical splitting failure mode (mode I), one crack coalescence failure mode (mode II), two crack coalescences failure mode (mode III) and no crack coalescence failure mode (mode IV). Compared with intact granite specimen, the disc specimen containing two holes fails with lower strength, which is closely related to the bridge angle. The failure strength of pre-holed specimen first decreases and then increases with the bridge angle. Finally, a preliminary interpretation was proposed to explain the strength evolution law of granite specimen containing two holes based on the microscopic observation of fracture plane.

Let $A_1$ and $A_2$ be nonzero complex idempotent and tripotent matrix, respectively. Denote a linear combination of the two matrices by A = $c_1A_1$ + $c_2A_2$, where $c_1,\;c_2$ are nonzero complex scalars. In this paper, under an assumption of $A_1A_2$ = $A_2A_1$, we characterize all situations in which the linear combination is tripotent. A statistical interpretation of this tripotent problem is also pointed out. Moreover, In [2], Baksalary characterized all situations in which the above linear combination is idem-potent by using the property of decomposition of a tripotent matrix, i.e. if $A_2$ is tripotent, then $A_2$ = $B_1-B_2$, where $B^2_i=B_i$, i = 1, 2 and $B_1B_2=B_2B_1=0$. While in this paper, by utilizing a method different from the one used by Baksalary in [2], we prove the theorem 1 in [2] again.

Incoterms mean the ICC official rules for the interpretation of trade terms which facilitate the conduct of international trade. Thus, the uncertainties of different interpretations of such terms in different countries can be avoided or at least reduced to a considerable degree. Nevertheless, Incoterms has been revised successively to adapt them to contemporary commercial practice. In particularly, substantive changes in Incoterms 2000 have been made in two areas: (i) the customs clearance under FAS and DEQ; and (ii) the loading and unloading obligations under FCA. But it should be stressed that the scope of Incoterms is limited to the contract of sale and not apply to the contracts of carriage, insurance and financing. Moreover, merchants wishing to use Incoterms 2000 should clearly specify that their contract is governed by 'Incoterms 2000'. It is particularly important to note that Incoterms are not dealt with a great number of problems, such as transfer of property rights, breaches of contract and exemptions from liability. Therefore, the contracting parties should clearly agree to the applicable law related their contract of sale, like the 1980 United Nations Convention on Contracts for the International Sale of Goods.
