The Polar Code entered into force on January 1, 2017. In this paper, we consider the problem of training a set of rate-compatible polar codes that are expurgated from the same mother code. in northwest Russia are not considered within the Polar Code area since they are ice-free year-round.32 In the Antarctic waters, the Polar Code will be applicable through the polar waters that is south of 60º south. A new International Code for Ships Operating in Polar Waters, better known as the Polar Code, will officially come into effect on January 1st. E. Şaşoğlu, Polarization and Polar Codes, Now Publishers Inc, 2012. We propose novel RL algorithms for designing nested polar codes [ 6 ] . Polar codes are unique in the way they split the channel into good and bad bit-channels. 2.15 Thin first-year ice means first-year ice 30 cm to 70 cm thick. 4 D Date & UTC Time A 6-digit group followed by a Z, the first 2 digits giving the day of the month, the next two digits giving the hour, and the last two digits giving the minutes. ) as part of its code (see Examples 2, 3 and 6, section 3.8). ice in the summer is decreasing, leading to reduced ice thickness and a projection of progressive sea ice loss of possibly up to 80 per cent by 2100. Increased navigation presents risks and challenges for the region’s ecosystems, species and indigenous peoples, who rely on the recurrence of sea ice formations.11 Navigation continues to be hazardous. ship's Polar Water Operational Manual TRAINING Masters, chief mates and officers in charge of a navigational watch must have ... training for other waters, including ice BACKGROUND INFO THE INTERNATIONAL CODE FOR SHIPS OPERATING IN POLAR WATERS WAS ADOPTED NOVEMBER 2014 BY THE IMO MARITIME SAFETY COMMITTEE IT APPLIES TO SHIPS OPERATING IN ARCTIC AND … requirements by ice class according to the ice condition and season is shown in Table 1-1-2. The Nautical Institute Ice Navigator Training and Accreditation Scheme Standard is relevant to Chapter 12 of the Polar Code - Manning and Training. These codes have a recursive structure tha t make it possible to encode and decode them within complexity O(N log N) for a code of block length N . Melting ice opens other business opportunities, too, with some regarding the Arctic as an emerging commercial hotspot. It was pointed out in [15] that an SC decoder can be implemented with Θ(N log(N)) complexity. Teaching & Academics Other Teaching & Academics 5G. Bhattacharya parameter based construction is used. Try Udemy for Business. Therefo re, once again polar codes provide an efficient solutio n. The e rror probability cu rves under SC decod ing are equal to the curves shown in the Figure 5 with 0 bits f or p ermutation s. With the loss of sea ice, water ways are opening and with it more ships can travel the area. Last updated 10/2020 English Current price $20.99. In accordance with the Polar Code, new and existing ships operating in polar waters shall have on board a valid Polar Ship Certificate establishing operational limitations, including limitations related to ship structural ice capabilities. Preview this course . Part II environmental protection requirements apply to ships that must comply with MARPOL and which operate in polar waters. This monograph starts with an explanation of channel polarization and how it is used to construct polar codes. For vessels with no Polar Ship Certificate, the Ice Class indicated on the vessel Classification Society Certificate. The Standard is consistent with the requirements for training under the Polar Code and adds to this a specified period of experience in ice for the award of Ice Navigator qualifications awarded by The Nautical Institute. The National Maritime Center has been and will continue to evaluate courses and issue letters attesting to the conformance of the course content with the training guidance in policy letters CG-OES 01-15 and CG-OES-01-16. These codes are naturally suited for decoding via successive cancellation (SC) [15]. Get your team access to 5,000+ top Udemy courses anytime, anywhere. Polar codes. In parallel to the developmen t of the Guidelines, the International Association of Classification Societies (IACS) has developed a set of Unified Requirements which, in addition to general classification society rules, address all essential aspects of construction for ships of Polar Class. The Polar Code covers the full range of design, construction, equipment, operational, training, search and rescue and environmental protection matters relevant to ships operating in the inhospitable waters surrounding the two poles. The smaller the number, the higher is the ice-breaking or ice-resistance performance of the ship. There are seven classes from PC1 to PC7. Academic Educator. Training 5 or more people? Because nested polar code construction (sequential information sub-channel selection) is inherently modeled as a Markov decision process (MDP), and RL algorithms can be applied to approach the optimum. (Figure 2) This boundary around the Antarctic continent also corresponds to the northern boundary of the Antarctic Treaty. Polar codes are a class of codes that can achieve the capacity of binary-input memoryless channels with certain symmetries. The course meets the requirements for STCW Sections A-V/4-1 and A-V/4-2 (Basic and Advanced Polar Code training) Key facts. 3 Sources of hazards 3.1 The Polar Code considers hazards which may lead to elevated levels of risk due to increased probability of occurrence, more severe consequences, or both: .1 Ice, as it may affect hull structure, stability characteristics, machinery systems, Check out Polar's high quality fitness trackers, heart rate monitors for running, triathlon and cross training & GPS-enabled cycling computers and sports watches for endurance training. The Polar Code applies to ships, depending on their international certification requirements, as follows: Part I safety requirements and Part I manning and training requirements apply to ships certified in accordance with SOLAS and which operate in polar waters. Sailing in polar waters brings on new challenges and risks, not only for the ships that sail them, but also for the polar environment and those dependent on it. The Polar Code is an international code for ships in the polar region. Polar codes, introduced by Arıkan in [15], are the first provably capacity achieving codes for arbitrary symmetric binary-input discrete memoryless channels (B-DMC) with low encoding and decoding complexity. Exploiting the inclusion property of rate-compatible polar codes which are defined by a single polar coding sequence as adopted in a 5G New Radio (NR) [2], we propose an efficient decoder training method via transfer learning. Channel code, especially polar code, is a good example for this endeavor. The vessel will comply with DNV GL’s Ice Class IACS PC (6), Polar Code B and be optimised for ice navigation. The concept of channel polarization is then generalized to non-binary input channels and to polarization kernels of sizes larger than the 2x2 kernel used by Arıkan in his seminal work on channel polarization. The Ice Class that corresponds to the Ice Class indicated on the Polar Ship Certificate. The Polar Code and Canada’s new regulations include a variety of safety and pollution prevention measures, including those related to vessel design and equipment, vessel operations and crew training. Duration: 5 Days Level: Short course Study location(s) New Zealand Maritime School Study method: Please contact us for more information. The Arctic Council recognized the IMO an observer on May 5 th, 2019. The Code establishes different categories of Polar-class ships depending on the strength of the hull construction, accounting for the vagaries of Polar ice and weather conditions. We will learn about… Sign in. A system of Polar Classes has therefore been developed to designate different levels of capability. The Polar Code addresses the unique hazards encountered by certain vessels that operate in the Arctic and Antarctic. For the seminal work on polar codes, please refer to: Erdal Arikan, ... Code Interface. Develop an intuitive understanding of polar codes. To address this issue along with other unique challenges, the IMO made the Polar Code in 2014.

Ice classes are intended mainly for ships capable of independent navigating in multi-year ice of Polar Waters. The interface to this class is as follows: constructor. The key code is in class PolarCode (C and MATLAB).
