Environmental/Regatta Buoy: Telemetry and Configuration

A monitorização ambiental é essencial para a tomada de decisões tanto na ciência como na indústria. Em particular, uma vez que a água é essencial à vida e a superfície da Terra é composta principalmente por água, a monitorização do clima e dos parâmetros relacionados com a água em ecossistemas sensíveis, tais como oceanos, lagoas, rios e lagos, é de extrema importância. Um dos métodos mais comuns para monitorar a água é implantar bóias. O presente trabalho está integrado num projeto mais amplo, com o objetivo de projectar e desenvolver uma bóia autónoma para a investigação científica com dois modos de funcionamento: (i) monitorização ambiental ; e (ii) baliza ativa de regata. Assim, a bóia tem duas aplicações principais: a coleta e armazenamento de dados e a assistência a regatas de veleiros autónomos. O projeto arrancou há dois anos com um grupo de quatro estudantes internacionais. Eles projetaram e construíram a estrutura física, compraram e montaram o sistema de ancoragem da bóia e escolherem a maioria dos componentes electrónicos para o sistema geral de controlo e medição. Este ano, durante o primeiro semestre, dois estudantes belgas - Jeroen Vervenne e Hendrick Verschelde – trabalharam nos subsistemas de recolha e armazenamento de dados (unidade de controlo escrava) e de telemetria e configuração (unidade de controlo mestre) assim como definiram o protocolo de comunicação da aplicação. O trabalho desta tese continua o desenvolvimento do subsistema de telemetria e configuração. Este subsistema _e responsável pela configuração do modo de funcionamento e dos sensores assim como pela comunicação com a estacão de base (controlo ambiental), barcos (baliza ativa de regata) e com o subsistema de recolha e armazenamento de dados. O desenvolvimento do subsistema de recolha e armazenamento de dados, que coleta e armazena num cartão SD os dados dos sensores selecionados, prossegue com outro estudante belga - Mathias van Flieberge. O objetivo desta tese é, por um lado, implementar o subsistema de telemetria e de configuração na unidade de controle mestre e, por outro lado, refinar e implementar, conjuntamente com Mathias van Flieberge, o protocolo de nível de aplicação projetado. Em particular, a unidade de controlo mestre deve processar e atribuir prioridades às mensagens recebidas da estacão base, solicitar dados à unidade de controlo escrava e difundir mensagens com informação de posição e condições de vento e água no modo de regata. Enquanto que a comunicação entre a unidade de controlo mestre e a estacão base e a unidade de controlo mestre e os barcos é sem fios, a unidade de controlo mestre e a unidade de controlo escrava comunicam através de uma ligação série. A bóia tem atualmente duas limitações: (i) a carga máxima é de 40 kg; e (ii) apenas pode ser utilizada em rios ou próximo da costa dada à limitação de distância imposta pela técnica de comunicação sem fios escolhida.

Environmental/Regatta Buoy: Sensing System

Um dos principais objetivos da ciência é perceber a natureza, i.e., descobrir e explicar o funcionamento do mundo que nos rodeia. Para tal, os cientistas precisam de coligir dados e monitorar o meio ambiente. Em particular, considerando que cerca de 70% da Terra é coberta por água, a coleta de parâmetros de caracterização da água de grandes superfícies é uma prioridade. A monitorização das condições da água é feita principalmente através de bóias. No entanto, as bóias disponíveis no mercado não satisfazem as necessidades existentes. Esta é uma das principais razões que levaram o Laboratório de Sistemas Autónomos (LSA) do Instituto Superior de Engenharia do Porto a lançarem um projeto para o desenvolvimento de uma bóia reconfigurável e com dois modos de funcionamento: monitorização ambiental e baliza ativa de regata. O segundo modo é destinado a regatas de veleiros autónomos. O projeto começou há um ano com um projeto do European Project Project [1] (EPS), realizado por quatro estudantes internacionais, destinado à construção da estrutura da bóia e à selecção dos componentes mais adequados para o sistema de medição e controlo. A arquitetura que foi definida para este sistema é do tipo mestre-escravo e é composta por uma unidade de controlo mestre para a telemetria e configuração e uma unidade de controlo escrava para a medição e armazenamento de dados. O desenvolvimento do projeto continuou com dois estudantes belgas que trabalharam na comunicação e no armazenamento de dados. Este projeto, que prossegue com o desenvolvimento da medição e do armazenamento de dados do lado da unidade de controlo escrava, tem os seguintes objetivos: (i ) implementar o protocolo de comunicação na unidade de controlo escrava; (ii ) coligir e armazenar os dados dos sensores no cartão SD em tempo real; (iii ) fornecer dados em tempo útil; e (iv) recuperar dados do cartão SD em tempo diferido. As contribuições anteriores foram estudadas e foi feito um levantamento dos projetos congéneres existentes. O desenvolvimento do projeto atual começou com o protocolo de comunicação. Este protocolo, que foi projetado pelos alunos anteriores, foi um bom ponto de partida. No entanto, o protocolo foi atualizado e melhorado com novas funcionalidades. Esta última componente foi um trabalho conjunto com Laurens Allart, que esteve a trabalhar no subsistema de telemetria e de configuração durante este semestre. O protocolo foi implementado do lado da unidade de controlo escrava através de uma estrutura de múltiplas actividades paralelas (multithreaded). Esta estrutura recebe as mensagens da unidade mestre, executa as ações solicitadas e envia de volta o resultado. A bóia é um dispositivo reconfigurável multimodo que pode ser expandido com novos modos de operação no futuro. Infelizmente, sofre de algumas limitações: suporta uma carga máxima de 40 kg e tem uma área de implantação limitada pela distância máxima à estacão base.

Royal Canadian Henley Regatta fonds, 1948-1983 (non-inclusive)

In 1903, the Canadian Association of Amateur Oarsmen had their request granted to make the Old Welland Canal at Port Dalhousie the permanent site of the Royal Canadian Henley Regatta. That same year organized rowing was established in St. Catharines when the St. Catharines Rowing and Canoe Club was formed. The Henley course was completed in July of 1903 after rowing was well underway. Although the Henley course served as an athletic and social event, rowing itself was slow to grow in the St. Catharines area. In 1915 the Regatta was cancelled for the duration of WWI and reinstated in 1919 when an increased public interest in the sport began to grow. Two years later, the Henley Aquatic Association was formed in order to control, maintain and improve the rowing facilities. This association was responsible for building a new clubhouse at Ann Street in 1921 and in 1931 completing the grandstands. Also in the 1930s the association had the Federal Government approve their appeal to have the Henley waters dredged for the first time. The St. Catharines Rowing Club re-located its headquarters to the Lakeport Road site. The 1940s brought more support from local groups and with that more events. In 1945, the St. Catharines Junior Chamber of Commerce began helping to organize and promote rowing locally. One of the new events at the Henley course was the "Schoolboy Championships". The growth of both rowing and the Henley continued growing through the 1950s. The Henley Aquatic Association acquired Reid's Island, now Henley Island, mainly through the efforts of Ted Nelson. In the 1960s, rowing really took off in St. Catharines. Women began to become recognized in the sport when Brock University created a women's rowing team. The second dredging was completed in 1964, leading to the creation of a world class rowing course. The facilities were upgraded to international standards and the Henley rowing course became Canada's first Class A FISA (Fédération Internationale des Sociétés d’Aviron or International Federation of Rowing Associations) rowing course. The first North American Rowing Championship was held at the Henley course in 1967 and again in 1970 for the third championship. The Canadian Henley Rowing Corporation formed in 1972, along with the St. Catharines, Parks and Recreation Department created the first rowing school for youth. Since 1960, St. Catharines has been at a competitive level with other International rowing courses. The city continues to produce Olympic level athletes today.

Towards Active Course Marks for Autonomous Sailing Competitions

This paper describes the environmental monitoring / regatta beacon buoy under development at the Laboratory of Autonomous Systems (LSA) of the Polytechnic Institute of Porto. On the one hand, environmentalmonitoring of open water bodies in real or deferred time is essential to assess and make sensible decisions and, on the other hand, the broadcast in real time of position, water and wind related parameters allows autonomous boats to optimise their regatta performance. This proposal, rather than restraining the boats autonomy, fosters the development of intelligent behaviour by allowing the boats to focus on regatta strategy and tactics. The Nautical and Telemetric Application (NAUTA) buoy is a dual mode reconfigurable system that includes communications, control, data logging, sensing, storage and power subsystems. In environmental monitoring mode, the buoy gathers and stores data from several underwater and above water sensors and, in regatta mode, the buoy becomes an active course mark for the autonomous sailing boats in the vicinity. During a race, the buoy broadcasts its position, together with the wind and the water current local conditions, allowing autonomous boats to navigate towards and round the mark successfully. This project started with the specification of the requirements of the dual mode operation, followed by the design and building of the buoy structure. The research is currently focussed on the development of the modular, reconfigurable, open source-based control system. The NAUTA buoy is innovative, extensible and optimises the on board platform resources.

Tony Biernacki Collection, 1967, 1979-1980, n.d.

Tony Biernacki's rowing career began in 1950 in Ottawa with his first Henley medal in 1952 in the coxless four. Sculling became his real means to success. Since 1955 he has posted record times and had numerous wins in the single. He represented Canada at the National Team between 1958 and 1967 and raced in the single at the British Empire Games and Pan Am Games (Chicago, silver medal) and pair at the Worlds in Yugoslavia in 1966. He won the Olympic trials in 1960 in Rome, but was unable to go. Upon his retirement from competition Tony was hired as the Team Manager for the following Pan Am Games. Tony was hired by Brock University in 1965 as a technician in the Chemistry Department. He became the head rowing coach that same year and began women’s rowing at the university level in Ontario with the first women’s crew in 1967. As Brock's second coach ever, he led the teams to championship form and kept the athletes racing through the summer regatta season. Tony remained at Brock from 1965 to 1980. He was one of the founders of The Canadian Masters Rowing Committee and he helped to initiate master's racing at the Canadian Henley. In 1985 he won the single, double and quad at the World Masters Regatta in Toronto. For a number of years he was also the world record holder for his age category on the C2 ergometer. His last heartfelt project was the construction of a wheelchair ramp at Resurrection Lutheran Church where he was an active member. Mr. Biernacki passed away on January 9, 1998 at the age of 66 after a valiant battle with cancer only a month after being awarded the Canadian Coaching Provincial Coaching Award. He is survived by his wife Janet, daughters Tracy, Tammy Pauls, and Tory Phannenhour, and son, Tony Jr. He is also survived by several grandchildren.

Body-mass management of Australian lightweight rowers prior to and during competition

Purpose: Although the body-mass management strategies of athletes in high-participation weight-category sports such as wrestling have been thoroughly investigated, little is known about such practices among lightweight rowers. This study examined the body-mass management practices of lightweight rowers before competition and compared these with current guidelines of the International Federation of Rowing Association (FISA). Quantification of nutrient intake in the 1-2 h between weigh-in and racing was also sought. Methods: Lightweight rowers (N = 100) competing in a national regatta completed a questionnaire that assessed body-mass management practices during the 4 wk before and throughout a regatta plus recovery strategies after weigh-in. Biochemical data were collected immediately after weigh-in to validate questionnaire responses. Responses were categorized according to gender and age category (Senior B or younger than 23 yr old, i.e., U23, Senior A or OPEN, i.e., open age limit) for competition. Results: Most athletes (male U23 76.5%, OPEN 92.3%; female U23 84.0%, OPEN 94.1%) decreased their body mass in the weeks before the regatta at rates compliant with FISA guidelines. Gradual dieting, fluid restriction, and increased training load were the most popular methods of body-mass management. Although the importance of recovery after weigh-in was recognized by athletes, nutrient intake and especially sodium (male U23 5.3 ± 4.9, OPEN 7.7 ± 5.9; female U23 5.7 ± 6.8, OPEN 10.2 ± 5.4 mg-kg(-1)) and fluid intake (male U23 12.1 ± 7.1, OPEN 13.5 ± 8.1; female U23 9.4 ± 7.4, OPEN 14.8 ± 6.9 mL.kg(-1)) were below current sports nutrition recommendations. Conclusion: Few rowers were natural lightweights; the majority reduced their body mass in the weeks before a regatta. Nutritional recovery strategies implemented by lightweight rowers after weigh-in were not consistent with current guidelines.

Impact of two different body mass management strategies on repeat rowing performance

Purpose: The present study was conducted to examine the impact of acute weight loss on repeat 2000-m rowing ergometer performance during a simulated multiday regatta. and to compare two different body mass management strategies between races. Methods: Competitive rowers (N = 16) were assigned to either a control (CON), partial recovery (RECpartial), or complete recovery (RECcomplete) group. Volunteers completed four trials, each separated by 48 h. No weight restrictions were imposed for the first trial. Thereafter, athletes in RECpartial and RECcomplete were required to reduce their body mass by 4% in the 24 h before trial 2, again reaching this body mass before the final two trials. No weight restrictions were imposed on CON. Aggressive nutritional recovery strategies were used in the 2 h following weigh-in for all athletes. These strategies were maintained for the 12-16 h following racing for RECcomplete with the aim of restoring at least three quarters of the original 4% body mass loss. Postrace recovery strategies were less aggressive in RECpartial; volunteers were encouraged to restore no more than half of their initial 4% body mass loss. Results: Acute weight loss increased time to complete the first at-weight performance trial by a small margin (mean 3.0, 95% CI -0.3 to 6.3 s, P = 0.07) when compared with the CON response. This effect decreased when sustained for several day,. Aggressive postrace recovery strategies tended to eliminate the effect of acute Weight loss on subsequent performance. Conclusion: Acute weight loss resulted in a small performance compromise that was reduced or eliminated when repeated over several days. Athletes should be encouraged to maximize recovery in the 12-16 h following racing when attempting to optimize subsequent performance.
