This paper explores the nature of multiple sluicing in English, which has two or more remnant wh-phrases in clause edge position. At the beginning part of the paper we argue against Nishigauchi's (1998) and Lasnik's (2007) Gapping analysis of multiple sluicing, which says that two remnant wh-phrases each actually occupies the left and right edge of a clause, with the in-between string of words undergoing Gapping. We rather argue that multiple sluicing in English is the same kind as found in Bulgarian and Serbo-Croatian. In other words, multiple sluicing in English is also derived by multiple wh-fronting which otherwise does not apply. We demonstrate that some important properties of the construction noted by Lmultiple sluicing, multiple wh-movement/fronting, sluicing, TP/IP-deletion, asnik (2007) under the Gapping approach to it can be accounted for in a principled way by our proposed analysis.

In this study, I attempt to show two points about Korean sluicing. First, the semantic source of the null subject of the copula phrase in Korean sluicing is a null pronoun. This null subject pronoun may refer to either the antecedent indefinite individual or the antecedent event of the preceding clause. Second, depending on the presence/absence of postpositions in the remant wh-phrase, sluicing constructions are classified into two different semantic types: i) an equative clause and ii) a predicational clause.

일반적으로 배사에 비해서 준설은 경제적 부담이 크기 때문에 배사를 효율적으로 운영하는 것이 중요하다. 본 연구에서는 2차원 하상변동 모형인 Nays2DH를 이용하여 홍수기 운영수위에 따른 배사효율을 낙동강에 위치한 달성보를 중심으로 분석하였다. 분석결과, 가동보의 수 만큼 배사수가 형성되었으며, 배사수로 상류에는 퇴적이 발생하는 것으로 나타났다. 또한, 홍수기 운영수위를 EL. 14.5 m로 운영하는 것이 EL. 14.0 m로 운영하는 것에 비해서 배사효율이 약 4.6% 증가하여 퇴사가 약 4.5% 감소하는 것으로 나타났다. 본 연구에서 분석한 홍수기 운영수위에 따른 배사효율의 변화를 고려한다면, 저수지 퇴사 저감 및 준설주기의 장기화가 가능할 것으로 판단된다.

Ellipsis is the figure of speech characterized by the deliberate omission of words that are obviously understood, but that must be supplied to make a construction grammatically or semantically complete. The purpose of this study is to examine how ellipsis affects its adjacent elements acoustically and phonologically in English VP-ellipsis, sluicing and gapping. In the experiment, the realizations by English native speakers are set as the criteria for the observing point and are compared to Korean speakers' realizations. For the results, while English native speakers utilized various acoustic information such as word duration and pitch range and phonological information such as pith accent realization in order to intend the cues for decoding the missing constituent, Korean English learners relied on only duration information and could not use various information effectively.

댐 퇴사량 예측방법은 수리학적 메커니즘을 이용하는 방법과 실측자료를 설계치로 적용하는 경험적 방법으로 구분할 수 있다. 전자는 물리적 해석방법으로 단기간에 이루어지는 현상을 규명하는데 적용할 수 있으며, 후자는 댐사수량 결정등 장기적인 설계변수 추정에 용이하게 이용할 수 있다. 이중 경험적 자료인 배사비 곡선식을 이용하면 월단위의 저수지 운영이 가능하며, 저류량에 대응하는 퇴사량을 정보변수로 추적하면 퇴사관리의 최적운영이 가능하다. 이와 같은 접근방법은 퇴사량에 의하여 시간적으로 변하는 댐 유효저수용량을 최적으로 관리할 수 있는 운영방안을 제공할 수 있다. 본 연구는 배사비 곡선을 이용한 장기 댐 퇴사량 예측방법을 제시하고 잇다. 개발된 방법을 중국 황하유역에 위치한 분하댐을 대상으로 장기간의 댐 운영을 모의하여 예상되는 퇴사량과 용수공급능력 분석에 적용하였다.

The expression no matter, combining with an interrogative clause X, expresses 'it doesn't matter what the value is of X' and displays many syntactic and semantic peculiarities. To better understand the grammatical properties of the construction in question, we investigate English corpora available online and suggest that some of the irreducible properties the construction displays can be best captured by the inheritance mechanism which plays a central role in the HPSG and Construction Grammar. We show that the construction in question has its own constructional properties, but also inherits properties from related major head constructions.

In order to be able to predict the maximum Annual Energy Production (AEP) for tidal power plants, an AEP optimization tool based on Evolutionary Algorithms was developed by ANDRITZ HYDRO. This tool can simulate all operating modes of the units (bi-directional turbine, pump and sluicing mode) and provide the optimal plant operation that maximizes the AEP to the control system. For the Swansea Bay Tidal Power Plant, the AEP optimization evaluated all different hydraulic and operating concepts and defined the optimal concept that led to a significant AEP increase. A comparison between the optimal plant operation provided by the AEP optimization and the full load operating strategy is presented in the paper, highlighting the advantage of the method in providing the maximum AEP.

Several methods have been proposed to control the sedimentation process. These include catchment management, flushing, sluicing, density current venting, and dredging. Flushing is used to erode previously deposited sediments. In pressurized flushing, the sediment in the vicinity of the outlet openings is scoured and a funnel shaped crater is created. In this study, the effect of localized vibrations in the sediment layers on the dimensions of the flushing cone was investigated experimentally. For this purpose, experiments were carried out with two bottom outlet diameters, five discharge releases for each desired water depth, and one water depth above the center of the bottom outlets. The results indicate that the volume and dimensions of the flushing cone are strongly affected by localized vibrations.

Shihmen reservoir was started in May 1963. The main purposes of Shihmen reservoir are for agriculture, power supply, flood control and tourism. Shihme Asn dam is an earth dam. Its crown height is 133m above mean sea level, with length 360 m, watershed 763.4 km², and maximum volume 309 million cms. Turbidity in Shihmen dam was severely affected by typhoons Aere (2004) and Masa (2005). Increased deposition after Aere was 28 million cms. Turbidity at Shihmen Canal Inlet is 3000 NTU (Nephelometry Turbidity Unit). Sediment sluicing strategies for downstream channel are demanded. Therefore, diversionary sediment preventing channel is planned in the upstream of Shihmen reservoir. Finally, turbid flow in tunnel channel is bypassed and diverted its flow down to downstream.

Metal cutting operations involve generation of heat due to friction between the tool and the pieces. This heat needs to be carried away otherwise it creates white spots. To reduce this abnormal heat cutting fluid is used. Cutting fluid also has an important role in the lubrication of the cutting edges of machine tools and the pieces they are shaping, and in sluicing away the resulting swarf. As a cutting fluid, water is a great conductor of heat but is not stable at high temperatures, so to improve stability an emulsion type mixed fluid with water and oil is often used. It is pumped over the cutting site of cutting machines as a state of atomized water droplet coated with oil by using jet. In this paper, to develop cutting fluid supplying nozzle to obtain ultra thin oil film for coating water droplet, a numerical analysis of three dimensional mixed fluid Jet through multi-stage nozzle was carried out by using a finite volume method. Jet flow characteristics such as nozzle exit velocity, development of mixing region, re-entrance and jet intensity were analyzed. Detailed mixing process of fluids such as air, water and oil in the nozzle were also investigated. It is easy to understand complex flow pattern in multi-stage nozzle. Important flow Information for advance design of cutting fluid supplying nozzle was drawn.
