The model consists of a physiological growth submodel based on the dynamic energy budget (DEB) model and a competition submodel for space and food. As a result of numerical simulation, the model can predict well the time histories of the averaged shell length and body weight from 11 September to 20 December in 2002. With growth of mussels, a new layer is produced in the mussel bank at the beginning of November. The mussels that form the inner layers stop food ingestion, so the shell length and body weight of them are smaller than those of mussels in the 1st layer. They continue living by consuming the reserved and gonadal materials. Hence the population number maintains the initial value of 100,000 individuals per square meters, however about half of the mussels are starved in the inner layer and the starved mussels do not contribute to food ingestion and oxygen consumption rates of the mussel aggregation (mussel bank). The oxygen consumption rate of the mussel bank is approximately predicted by the developed model, which has less obscurity on the parameter values of respiration rate than the existing SFG based model.","PeriodicalId":268341,"journal":{"name":"OCEANS 2006 - Asia Pacific","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126003204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the price of the international crude oil holds 60-70 US dollars per barrel recently, the fishing and working boats have seen a big problem of no more sailings caused by the oil price increase. In view of this matter, You-Nam Marine Engineering Co. and KIMFT in Busan, Republic of Korea, jointly researched and developed the mixing clean heater as fuel oil pretreatment system that Bunker A or MF 30 grade oil could be used instead of marine diesel or gas oil. These days, marine gas oil is at least twice as expensive than Bunker-A oil. This system consists of an electric driven motor, shaft, propeller, friction plate and heating coil, also auxiliary parts such as 1st filter and 2nd magnetic filters etc. The advantages of this mixing clean heater are reducing the fuel oil sludge generation, increasing engine output power, reducing the trouble in moving parts for exhaust and intake valves, and also if we change the fuel oil converting marine gas oil or marine diesel oil to Bunker-A oil or MF 30 grade oil, direct or indirect fuel oil cost can be saved up to 35% ~ 50% for fishing boats or any kind of working boats. In this research, we developed the mixing clean heater as fuel oil pretreatment system that Bunker-A or MF 30 grade oil could be used instead of expensive marine diesel oil or marine gas oil used in low speed engines or medium speed engines. The mixing clean heater has functions such as fuel oil heating for appropriate viscosity, reducing the sludge, no carbon deposit on the heating coil and removing steel rust etc.","PeriodicalId":268341,"journal":{"name":"OCEANS 2006 - Asia Pacific","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125646159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So, main development efforts were primarily focused on the solution of problems induced with vertical and vertically inclined hydroacoustic telemetry channels in deep waters. In conditions of most practical interest, rather high bit rates, usually between 1 and 4 kbps (sporadically up to 6.5 kbps), were registered and thus experimentally proved. Keeping in view the limitations on given frequency range (effectively from 8 to 16 kHz) and on power consumption (less than 80 W), the practically achieved performance confirmed advantages of the sweep-spread carrier technology for data telemetry under tricky environmental conditions in practical oceanographic applications. Working from research vessel \"Sonne\" the surface telemetry unit was exposed to high-level broadband noise produced by ship mechanisms (due to strong wind and waves a positioning system of the ship constantly switched on and off different positioning mechanisms on board). Owing to permanent ship movements, receive and transmit conditions were continuously varying. Strong water flows in vicinity of surface modem provided fast and strong deviations of the modem from its normal (vertical) position. Variations in modem arrangement and presence of multiple reflecting objects provided conditions, in which the multipath structure was especially intricate. The paper contents trials description, theory and analysis of the S2C acoustic link working under given conditions.","PeriodicalId":268341,"journal":{"name":"OCEANS 2006 - Asia Pacific","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133905797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
