Submitted to the Faculty of Arts in fulfillment of the requirements for the Degree Mater of Arts in the Department of Criminal Justice at the University of Zululand, South Africa, 1995. / This research project which is the first of its kind in South Africa, entails a criminological study of harbour policing in South Africa. Firstly, it is primarily concerned with the historical development of harbour policing prior to its inception in 1916 in terms of the proclamation of The Railways and Harbours Regulation, Control and Management Act, Act 22 of 1916, as well as the period following 1916 which paved the way for the dawn of the reorganization of Harbour Policing as an official police force on 1 July 1934 and thereafter. Secondly, this investigation aims at describing maritime jurisdiction by means of emphasizing the existence of different conventions, such as the Hague Convention of 1930, the Geneva Convention of 1958 and the Law of the Sea Convention of 1982, as no Parliament exists to pass laws pertaining to the sea. It appears from this investigation that maritime fraud, theft of cargoes on the open sea, piracy and the illegal sinking of ships, oil pollution, etc. are matters of great concern for harbour policing. Functional harbour policing seems to be dependent upon various role players, such as : * The- Sea Fishery Act (Act 12 of 1988), for the protection of our sea resources; The Merchant Shipping Act (Act 57 of 1951); The Department of Transport (Maritime section) to ensure a clean and safe sea; The Defence Force (Navy} whose main task is to defend; The Natal Parks Board for conservation of fauna and flora; Customs and Excise Control to protect state funds; The National Sea Rescue Institute to assist people in distress at sea: and The South African Police service tor execution of the law and law enforcement. Proactive functional harbour policing is based on short-term crime prevention techniques such as visible role-fulfilment by means of patrolling l while reactive harbour policing entails the investigation of crimes committed on the sea, in the harbour and areas adjacent to the seal such as crimes mala in se and crimes mala prohibita. This investigation rests on documentary studies I personal interviews and an empirical analysis and description of all types of crimes and functional activities handled by the Water Wing of the South African Police Service. * * * * Recommendations include, inter alia, the following : * Follow-up research on harbour policing to keep abreast with overseas development; The role of the South African Narcotics Bureau (SANAB) with regard to the smuggling of dangerous producing and habit forming substances such as drugs as well as the illegal smuggling of weapons and other material; Closer co-operation between different units of the Water Wing and other "stakeholders" with regard to creating a sound knowledge of legislation pertaining to the sea: Education of criminal justice practitioners on the one hand and the general public on the other hand with regard to legislation applicable to the sea and adjacent areas; and The upgrading of security measures in South African harbours.

Sjöräddningssällskapet (SSRS) är en frivillig organisation som står för majoriteten av alla sjöräddningsinsatser i Sverige. Det senaste året har verksamheten fått en ökad mängd uppdrag till följd av bland annat att fler svenskar väljer att fira somrarna hemma i Sverige.Mitt examensarbete kretsar kring hur man med hjälp av modern teknik kan utforma en fjärrstyrd räddningsfarkost som kan underlätta för Sjöräddningssällskapet under mindre akuta uppdrag, så kallade medlemsuppdrag, eller förebyggande räddningsinsatser som dom även kallas. Dessa uppdrag utgör majoriteten av verksamhetens samtliga uppdrag. Arbetet har genomförts i samarbete med Sjöräddningssällskapet och har följt en klassisk designmetodik som utgår ifrån undersökningar och intervjuer med personer som berör det valda problemområdet, i syfte att ge arbetet en relevant och gedigen grund. / Swedish Sea Rescue Society (SSRS) is a voluntary organization that is responsible for the majority of all sea rescue missions in Sweden. In the past year, the organization has received an increased number of mission as a result of, among other things, more Swedes choosing to celebrate summers at home in Sweden.My thesis revolves around how to use modern technology in order to design a remotely controlled rescue vessel that can facilitate the Swedish Sea Rescue Society during less urgent missions, so-called membership missions, or preventive rescue missions as they are also called. These missions make up the majority of the organizations missions. The project has been carried out in collaboration with the Swedish Sea Rescue Society and has followed a classic design methodology based on research and interviews with people who touch on the chosen problem area, in order to give the project a relevant and solid foundation.

Thesis (MA)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: Saving the life of another person cannot be measured in monetary terms. It is also impossible to describe the satisfactiori of carrying out a successful rescue to anybody. However, the disappointment and sense of failure when a rescue mission fails and a life is lost, is devastating. Many rescue workers, including those of the National Sea Rescue Institute (NSRI), have experienced this overwhelming sense of failure. Rescue workers often dwell on failed rescue attempts, wishing that they could have arrived on the scene earlier or knew where to start looking for people. The fact that lives are still lost, despite the best efforts of rescue workers, points to the need to improve on life saving techniques, procedures, equipment and technology. Providing the NSRI with a workable tool to help them manage and allocate resources, plan a rescue, determine drift speed and distance or create search patterns, may one day be just enough to save one more life. With this goal in mind, a search and rescue application, called RescueView, was developed utilising ArcView 3.2a. This application was specifically designed for use by the NSRI, and it will be used as a command centre in all NRSI control rooms and for all rescue efforts. / AFRIKAANSE OPSOMMING: Om die lewe van 'n ander persoon te red, kan nie in geldwaarde gemeet word nie. Dit is ook onmoontlik om aan enige iemand die bevrediging van 'n suksesvolle redding te beskryf. Die terleurstelling en gevoel van verlies is egter baie groot wanneer 'n reddingspoging misluk en 'n lewe verloor word. Menige reddingswerkers, insluitend dié van die Nasional Seereddingsinstituut (NSRI), het al hierdie oorweldigende gevoel van mislukking ervaar. Reddingswerkers tob dikwels oor onsuksesvolle reddingspogings en wens dat hulle vroeër op die toneel aangekom het of geweet het waar om vir mense te begin soek. Die feit dat lewensverlies steeds plaasvind, ten spyte van reddingswerkers se beste pogings, dui op die behoefte om lewensreddingstegnieke, -prosedures, -toerusting en -tegnologie te verbeter. ( Deur die NSRI met 'n werkbare instrument te voorsien, wat hulle kan help om hulpbronne te bestuur en toe te wys, 'n redding te beplan, dryfspoed en -afstand te bepaal of soekpatrone te skep, mag eendag dalk net genoeg wees om nog 'n lewe te red. Met hierdie doel in gedagte is RescueView, 'n soek- en reddingsapplikasie, deur middel van ArcView 3.2a ontwikkel. Hierdie applikasie is spesifiek ontwerp vir gebruik deur die NSRI en dit sal as beheersentrurn in alle NSRI kontrolekamers en vir alle reddingspogings gebruik word.

The work summarized in this report aims to investigate how a drone airplane design can be optimized to create a safer and more efficient sea rescue by providing staff with an early picture, performing search missions and aiding communication through visual contact. A flying wing is in theory one of the most efficient designs for a fixed wing aircraft, at the same time as it also offers high structural efficiency for its given size. In this report, an overview of aerodynamics, stability and flying quality for a flying wing is discussed and analysed. XFLR5 was used for this project, and a comparison between the analytical results and wind tunnel test data for a prototype was conducted. A strong correlation was found between the theoretical analyses and the wind tunnel data. A simple control solution using only one set of elevons has been proposed and simulated, resulting in Level 1 dynamic stability for all modes except Dutch-roll (where the drone’s damping is 𝜁𝑑𝑟=0.07 and the requirement for Level 1 is 𝜁𝑑𝑟=0.08). For the range of angle of attack used, the autopilot system will have to trim the drone in flight to achieve stability. As the drone only has one set of control surfaces there will be a loss of efficiency in this scenario, meaning that 𝐶𝐿/𝐶𝐷 = 15.7 for loiter speed of 15 𝑚/𝑠 and 7.9 for full speed at 35 𝑚/𝑠. In regular flight, with a total mass <1 𝑘𝑔, the drone is able to fly at full speed for 214 𝑘𝑚 or loiter for 6.3 ℎ with a battery package of 130 𝑊ℎ. As such, the objective of this project was achieved, and the proposed design met the given requirements. / betet som sammanfattas i denna rapport syftar till att undersöka huruvida ett drönar-flygplan bäst kan utformas för att skapa en säkrare och effektivare sjöräddning genom att ge räddningspersonalen en tidig överblick, utföra sökuppdrag och bistå till kommunikation genom visuell kontakt. En flygande vinge är i teorin en av de mest effektiva konstruktionerna för ett flygplan, likaså erbjuder den en hög strukturell effektivitet för en given storlek. I denna rapport diskuteras och genomförs en översikt över aerodynamik, stabilitet och flygkvalitet hos en flygande vinge. XFLR5 användes för detta projekt, och en jämförelse mellan analysresultaten och ett vindtunneltest med en prototyp genomfördes. I allmänhet är överenskommelsen mellan de teoretiska analyserna och vindtunneldatan god. En enkel lösning som enbart består av en uppsättning kontrollytor har föreslagits och simulerats, vilket resulterar i en Nivå 1 dynamisk stabilitet för alla lägen utom Dutch-roll, där drönarens dämpning är 𝜁𝑑𝑟 = 0.07 och kravet för Nivå 1 är 𝜁𝑑𝑟 = 0.08. Autopilotsystemet behöver trimma drönaren under flygning för att uppnå nödvändig stabilitet för det spann av attackvinklar som används, med endast en uppsättning kontrollytor, vilket minskar effektiviteten för BWB-drönaren till 𝐶𝐿/𝐶𝐷=15.7 för cirkuleringshastigheten på 15 𝑚/𝑠 och 7.9 för full hastighet vid 35 𝑚/𝑠. Drönaren kan flyga i full hastighet i 214 𝑘𝑚 eller cirkulera runt olycksplatsen under 6.3 timmar med ett batteripaket på 130 𝑊ℎ, med en vikt som är lägre än 1 𝑘𝑔. Målen med detta projekt uppnåddes och drönaren utformades enligt kraven.

The Swedish Sea Rescue Society (SSRS) is a non-profit organization that performs sea rescue operations around Sweden’s coast line and lakes. In their sea rescue work, they came up with an idea that could be used to prevent accidents that are caused by harsh weather. According to Trafikverket, two out of three accidents at sea can be related to bad weather. Today, the SSRS have a weather application that you can download and note the weather where the different national weather stations are located. The data for this application is gathered from SMHI and YR.no. The SSRS wants to complement this data with their own weather measurements from specific places in e.g. the archipelago. To be able to do this they want to develop a portable and self-sufficient weather station. The weather station will be overseen by the SSRS rescue personnel, who will transporting and installing the weather station onto specific place. The weather station shall express the SSRS design profile, blend into the environment, and be easy to transport and install. The SSRS doesn’t have any prior products of that sort, and through a market study of competing or similar products / ideas, it became clear that this product would be innovative. By studying the environment which the weather station will be placed and faced with, and who the different users are and their requirements, a requirement framework was established which the end result would need to fulfil.  Through different methods and analysis of what people from different background think and feel about the archipelago, a joint view of what the archipelago associates with was established in order for the weather station to be designed to t into the desired environment. Studies and innovation around technical functions that the weather station should be able to perform, have led to different design restrictions in order for the weather station to be able to work. The end result of the project is a concept of a self-sufficient and portable weather station, making it possible to be transported and installed by one person. The design of the weather station has been made to make it blend into the environment and up close be able to identify as a product of the SSRS. The design has also been made to be user friendly for those handling it. / Svenska Sjöräddningssällskapet (SSRS) är en ideell organisation som utför sjöräddningar runt Sveriges kuster och insjöar. I deras sjöräddningsarbete, har de kommit på en produktidé för att förebygga olyckor orsakade av oväder. Tra kverket har noterat från deras statistik att två av tre olyckor på sjön kan kopplas till dåligt väder. SSRS har idag en väderapplikation som man kan ladda ner och notera vädret omkring där de nationella väderstationer är placerade. Informationen till applikationen baseras på data hämtad från SMHI och YR.no. SSRS upplever att de vill komplettera denna information med egna vädermätningar från specifika platser i exempelvis skärgården. För att kunna göra detta behövs en portabel, självförsörjande väderstation. Väderstationen skall hanteras av SSRS räddningspersonal som transporterar ut och installerar väderstationen på de specifika platserna. Denna väderstation ska då uttrycka SSRS designprofil, smälta in i naturen, och vara lätt att transportera och montera. SSRS har inte någon tidigare liknande produkt, och genom marknadsundersökning konstaterades att denna produkt är mycket innovativ. Genom att studera miljön som väderstationen kommer placeras i och utsätta för, samt vilka de olika användarna är och deras krav på produkten, kunde ett ramverk skapas inom vilket projektets resultat skulle uppfylla. Genom olika metoder och analyser av vad personer med olika bakgrund tycker och tänker om skärgården, kunde en gemensam bild skapas i där väderstationen har samma uttryck. Studier och innovation kring tekniska funktioner som väderstationen skulle kunna utföra, har lett till designrestriktioner för att väderstationen ska kunna fungera. Slutresultatet av projektet är ett koncept på en självförsörjande portabel väderstation, vars funktioner gör det möjligt för en person att transportera och installera stationen. Formgivningen av väderstationen har skapats för att få den att smälta in i naturen, och på nära håll kunna identi eras som en produkt från SSRS. Designen av väderstationen har även gjorts användarvänlig för att förenkla hanteringen av den.

The usage of autonomous vehicles is starting to appear in several different domains and the domain of public safety is no exception. Wallenberg Artificial Intelligence, Autonomous Systems and Software Program (WASP) has created a research arena for public safety (WARA-PS) to explore experimental features, usages, and implementation of autonomous vehicles within the domain of public safety. Collaborating in the arena are several companies, universities, and researchers. This thesis examines, in collaboration with Combitech, a company partnered in WARA-PS, how the implementation of autonomous vehicles affects the sociotechnical system of a search and rescue operation during a drifting boat with potential castaways. This is done by creating a case together with domain experts, analyzing the sociotechnical system within the case using cognitive work analysis and then complementing the analyses with the unmanned autonomous vehicles of WARA-PS. This thesis has shown how the WARA-PS vehicles can be implemented in the case of a drifting boat with potential castaways and how the implementation affects the sociotechnical system. Based on the analyses and opinions of domain experts’ future guidelines has been derived to further the work with sociotechnical aspects in WARA-PS. / WARA-PS
