The article criticizes the report’s conclusions to the extent they suggest that the operation of some MASS categories can be reconciled with the existing COLREGS rules by mere rule interpretations or the use of equivalences and warns that reliance on either approach would likely dilute the rules in their application to the far more numerous manned vessels. The article concludes that the advent of MASS will require amendments to the COLREGS.","PeriodicalId":198407,"journal":{"name":"IRPN: Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131267106","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}

Industrial robots are unique in that they are a substitute for labor, whereas other types of physical assets are largely a complement for labor. As a result, robots provide a hedge for fluctuations in the price of labor. Our model shows that robot deployment reduces a firm's risk, decreases equilibrium interest rate, and increases debt capacity. We test these predictions using firm-level panel data on robot deployment in five Chinese provinces across multiple industries. Consistent with the role of robots in hedging labor price risk, robot adoption leads to higher leverage and lower cost of debt, at both the extensive and intensive margins. The staggered nature of the introduction of robot-friendly policies across provinces and industries allows us to make causal claims. The model's more refined predictions, concerning the effects of labor contribution and robot-labor substitution on the strength of the relation between robot adoption and corporate financing, are also borne out in the data.","PeriodicalId":198407,"journal":{"name":"IRPN: Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126675607","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}

It is advisable to regulate the voltage within a narrow range of its nominal value (±5% range around its nominal values). Consequently, reactive power control is necessary to control dynamic voltage fluctuations under different system conditions and thus improve the performance and transmission of the distribution system. In this paper, a fixed three-phase voltage (VSI) source compensator is searched for. The paper aims to explain how STATCOM is used to improve the AC system power factor and voltage regulation, and thus improve the performance of transmission and distribution lines. A STATCOM fast fixed compensator is required to produce or absorb reactive energy in order to provide the necessary reactive energy balance in the transmission and distribution system. Modern reactive power compensation uses a voltage inverter (VSI). This STATCOM application has achieved a unit power factor transmission system, which reduces active energy loss by 38.7% thus reducing energy costs, as well as increasing the capacity of the transmission system.","PeriodicalId":198407,"journal":{"name":"IRPN: Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129075717","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}

Order anticipation is an integral part of high-frequency traders' strategies. Hence, some participants may have economic incentive to encrypt noise in the data. We use machine learning to identify five types of algorithmic imprints that hinder the processing of auction information and have the encrypted noise characteristics. Our approach rests on the shifted wavelet tree (Yunyue and Shasha (2003)), a burst detection indicator, and the dynamic time warping similarity measure (Skutkova, Vitek, et al. (2013)). We show that market participants can adapt their trading to the presence of encrypted noise by filtering data in real time, thus clarifying the price discovery process. This could reveal the presence of informed traders. The methodology deployed is adaptable to different environments, including continuous trading.","PeriodicalId":198407,"journal":{"name":"IRPN: Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126752384","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}

The developed family of models utilises a class of transformation functions known as the Tukey g-and-h transformation to create a new class of warped spatial Gaussian process model which can support various desirable features such as flexible marginal distributions, which can be skewed and/or heavy-tailed. The resulting model is widely applicable for a wide range of spatial field reconstruction applications. To utilise the model for such applications in practice, we first need to derive the statistical properties of the new family of Tukey g-and-h random fields. We are then able to derive five different objectives to perform spatial field reconstruction. These include the Minimum Mean Squared Error (MMSE), Maximum A-Posteirori (MAP) and the Spatial-Best Linear Unbiased (S-BLUE) estimators as well as the Spatial Regional and Level Exceedance estimators. Extensive simulation results and real data examples show the benefits of using the Tukey g-and-h transformation as opposed to standard Gaussian spatial random fields as is classically utilised.","PeriodicalId":198407,"journal":{"name":"IRPN: Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129751429","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}
