a study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
A simplified model for bottom trawl fishing gears
Computational modeling is a valuable complementary tool to assess behavior of bottom trawl fishing gears. A simplified model of the gear that mainly affects to the net is proposed. The model is constrained to steady towing conditions, flat seabed and gear symmetry. Simulations proportionate a number of relevant outcomes like distribution of tensions at the warp, balance of forces at the otterbo...
متن کاملA Petri-net Model for Operational Cycle in SCADA Systems
Supervisory control and data acquisition (SCADA) system monitors and controls industrial processes in critical infrastructures (CIs) and plays the vital role in maintaining the reliability of CIs such as power, oil, and gas system. In fact, SCADA system refers to the set of control process, which measures and monitors sensors in remote substations from a control center. These sensors usually ha...
متن کاملElectronic Monitoring of Seabird Interactions with Trawl Third-wire Cables on Trawl Vessels - A Pilot Study
Archipelago Marine Research Ltd. was selected by the Alaska Fisheries Science Center to test electronic monitoring (EM) equipment for possible use to examine seabird interactions with trawl third-wire cables on trawl vessels. This pilot study involved field testing of EM systems on shoreside delivery and head and gut bottom trawl vessels conducting operations in the Bering Sea, U.S. Exclusive E...
متن کاملForecasting of Warp Tension Time Series while Towing a Trawl Net
Dynamical relation between ship's motions and warp tension while towing a trawl net was identified by the use of statistical method to be the multivariate AR model. Using this system identification method, the various towing system parameters were obtained by analysing the records of measuring ship's motions and warp tension during the fishing operations in several sea conditions. Based on thes...
