Texte intégralRésumé :
Fire alarm and emergency broadcasting sound are important in fire and disaster situations. For the clear presentation of the fire alarm and emergency broadcasting sound to occupants of buildings, some guidelines and requirements were established. In NFPA 72 and BS standard, a specific alarm sound level for alarm sound of residential facilities was proposed and Speech Transmission Index(STI) was regulated for the emergency broadcasting system. In the fire and disaster situation, one of the important facility is a mechanical and electrical system to maintain water and electricity supply. To maintain this function in the buildings, clear presentation of emergency broadcasting sound to the workers in the mechanical and electrical room is crucial for the emergency operation of the system. In this study, the noise level in the mechanical rooms and electricity facilities of more than 40 years old office building were measured. Also, audibility and room acoustic properties such as reverberation time and STIwas simulated using Odeon 12. In order to deliver emergency broadcasting sound more clearly, sound absorption material and a soundproof chamber for noisy devices are needed. Also, the emergency broadcasting system in noisy facilities should be improved to produce the broadcasting sound louder and clearer.

Wahyuni, Hermin Indah. « Complexity and Adaptive System of Television Broadcasting : The Reflection of Autopoetic Mechanism of Indonesian Television Broadcasting System ». Jurnal Ilmu Sosial dan Ilmu Politik 20, no 3 (4 août 2017) : 189. http://dx.doi.org/10.22146/jsp.27204.
Texte intégralRésumé :
This article aims to describe a model of a robust adaptive system which suits the context of situation in Indonesian as an archipelago, as well as developing and democratic values-based country. It mainly focuses on how the autopoetic mechanism in Indonesian television broadcasting system is. Autopoetic mechanism is self-reference orientation. The process in which the system orient to reduce their problem by building the internal structure to cope with it. The research process was done in 2014 until 2016. Methods applied in this research is qualitative research. Several methods that were employed are observation, in-depth interview, and focus group discussion. It would be measured and analysed with three aspects: communication, temporal and differentiation aspect. The findings suggest that building a robust system means establishing a “strong and adaptive” broadcasting system in Indonesia that strengthens each sub-system in the Indonesian broadcasting system in order to capture what the public demands. In this level it takes a comprehensive view of the decision-makers to design a broadcasting system that continues to answer the demanding environment through its communication function, growing temporal through continuous evolution and develop functions through a process of differentiation. If these three functions can work continuously, Indonesian broadcasting system will be stronger and more adaptive with their complex external environment. The main argument of this paper is Indonesian Broadcasting System faces a very complex environment television, however their adaptive and autopoetic mechanism is still weak to cope with the challenges.

Canadian Journal of Civil Engineering 32, no 2 (1 avril 2005) : 372–87. http://dx.doi.org/10.1139/l04-099.
Texte intégralRésumé :
Regional seismic risk estimations are needed in southwestern British Columbia, since it is one of the most seismically active and highly populated regions in Canada. Regional estimations typically involve a large number of buildings, which makes it necessary to establish a building classification system, where the average response to earthquake shaking is assumed to be similar within each building class. In this study, buildings in British Columbia were divided into 31 classes based on their material, lateral load bearing system, height, use, and age. A damage probability matrix (DPM) was then developed for each building class which describes the probability of being in a certain damage level (i.e., light, moderate, heavy, etc.) given the ground shaking intensity. Next, a probability distribution function was fit to the discrete probability values at each intensity level. The products of this study, the building classification system, the DPMs, and the probability distribution functions will allow regional damage and loss estimations in the area.Key words: seismic risk, vulnerability, building classification, structural system, building response, damage, probability.

Texte intégralRésumé :
Generally, there is a high background noise and long reverberation time and poor speech intelligibility in exhibition space due to its big crowd and often commercial promotional activities so that communication is very hard, commercial activities broadcasting system is also difficult to ensure that customers can clearly hear the propaganda content. In this paper, through measured background noise of the new exhibition center in Chengdu, we found the acoustic problem in exhibition space, then we did simulation analysis in some exhibition building and took some acoustical process to get a good sound field.

Texte intégralRésumé :
AbstractAlthough countries protect and promote freedom of expression in different ways, free speech can be understood to have two basic aspects in democratic constitutional systems: non-censorship and diversity of voices. This article examines how the approach to free speech in Sweden contains both these aspects. Selected comparisons with the US First Amendment, and German broadcasting law, indicate the value in the Swedish approach but also reveal challenges that it faces if free speech’s dual aspects are not clearly recognised – a danger that some contemporary statements suggests is real. Articulating free speech in terms of both non-censorship and diversity may aid Swedish parliamentary processes to uphold important structural aspects of the freedom, but it would also bring into focus larger questions about the limits of parliamentary processesalonein building a viable system of freedom of expression for the future.

Texte intégralRésumé :
This paper examines how early media reform work evolved from political activism into a system-building advocacy campaign in support of Schools of the Air between 1930 and 1940. Calling upon archival work that focuses on 1935–1940 records, it examines how prominent activist groups the National Committee for Education by Radio (NCER) and the National Advisory Council for Radio in Education (NACRE) shifted their strategic approaches to adjust to the “public interest” mandate of the Communications Act of 1934. Though scholarship has chronicled disagreements between the NCER and NACRE over how to best support educational broadcasting, a dialectical interplay emerged after the act during the New Deal due to the influence of the Federal Radio Education Committee (FREC). FREC inspired A.G. Crane of the NCER to build the Rocky Mountain Radio Council (RMRC). The RMRC was the first sustainable educational media network, and the group coined the term public broadcasting. While the Communications Act signaled the end of the first wave of media activism, the policy also inspired reformers to develop a new system-building strategy that set the groundwork for NPR and PBS.

Ullah, Mahib, Xingmei Li, Muhammad Abul Hassan, Farhat Ullah, Yar Muhammad, Fabrizio Granelli, Lucia Vilcekova et Tariq Sadad. « An Intelligent Multi-Floor Navigational System Based on Speech, Facial Recognition and Voice Broadcasting Using Internet of Things ». Sensors 23, no 1 (27 décembre 2022) : 275. http://dx.doi.org/10.3390/s23010275.
Texte intégralRésumé :
Modern technologies such as the Internet of Things (IoT) and physical systems used as navigation systems play an important role in locating a specific location in an unfamiliar environment. Due to recent technological developments, users can now incorporate these systems into mobile devices, which has a positive impact on the acceptance of navigational systems and the number of users who use them. The system that is used to find a specific location within a building is known as an indoor navigation system. In this study, we present a novel approach to adaptable and changeable multistory navigation systems that can be implemented in different environments such as libraries, grocery stores, shopping malls, and official buildings using facial and speech recognition with the help of voice broadcasting. We chose a library building for the experiment to help registered users find a specific book on different building floors. In the proposed system, to help the users, robots are placed on each floor of the building, communicating with each other, and with the person who needs navigational help. The proposed system uses an Android platform that consists of two separate applications: one for administration to add or remove settings and data, which in turn builds an environment map, while the second application is deployed on robots that interact with the users. The developed system was tested using two methods, namely system evaluation, and user evaluation. The evaluation of the system is based on the results of voice and face recognition by the user, and the model’s performance relies on accuracy values obtained by testing out various values for the neural network parameters. The evaluation method adopted by the proposed system achieved an accuracy of 97.92% and 97.88% for both of the tasks. The user evaluation method using the developed Android applications was tested on multi-story libraries, and the results were obtained by gathering responses from users who interacted with the applications for navigation, such as to find a specific book. Almost all the users find it useful to have robots placed on each floor of the building for giving specific directions with automatic recognition and recall of what a person is searching for. The evaluation results show that the proposed system can be implemented in different environments, which shows its effectiveness.

Texte intégralRésumé :
Nowadays, television is used for educational purposes. It is easily accessible through air-to-air broadcasts and can be connected via satellite. What is witnessed on a television screen is all image and sound elements. Many people feel uncomfortable watching television shows because when the television is used, the broadcasts that appear are not all images and sounds that can be seen and heard properly. Most antennas used by every household are patented in a certain position. Based on the existing description, the problem that would be solved is how to design an IoT-based TV broadcasting antenna system to make it easier to watch television with clear broadcasts and good sound without changing the antenna's position manually. With the design method, the tool to be made consists of a flowchart and a circuit design, namely, building a system with inputs, processes, and outputs. The automatic TV broadcasting antenna system based on the internet of things (IoT) is a system that points the antenna in the best position for each selected broadcast that can be controlled via Android using the Blynk IoT Application. After that, the test was carried out by taking data at two locations for the IoT antenna. The assessment results showed that each location was different, and the position of the antenna direction would also be different, so the location of the antenna must be changed by changing the angle contained in the Arduino IDE software.

On Jan 3 2006, the Legislative Yuan had passed through the Statute for Disposing of Public-Sector Stock Shares in Wireless TV Businesses, which confirms to support a public-owned broadcasting enterprise by merging CTS (Chinese Television System), TITV (Taiwan Indigenous Television), Hakka TV (Hakka Television Service) and MACTV (Taiwan Macroview TV) with current PTS (Taiwan Public Television Service). It took six years to pass through the statute and enforce the policy of building the public broadcasting system. The executive authorities also appeared to be indecisive. It is an issue worthy of serious concern as to how the public broadcasting system in Taiwan could be built. From the perspectives of state theories and critical political economy of communications and through secondary analysis and in-depth interview, we explored three key subjects in this study: the background of the TV publicizing policy, how actors in the policy process interact and contribute to the public broadcasting system, and state and society relations. The study found that there are political and media factors which lead to the proposal to build public broadcasting system. In the first place, political authority had not withdrawn from the media. In addition, the laisser-faire media policies after liberalization had brought about vicious competition in media industry. Therefore, media reform activists, mainly media academics, proposed building public broadcasting system through helping DPP presidential candidate writing Communication White Book. The study also found that state autonomy was restricted by civil society, which caused state was not able to make policies advantageous to itself at will. That’s the reason why the executive authorities’ position on publicizing policy was ambiguous and indecisive. The active involvement in policy making process of social movement groups (especially the media reform group) prevented further privatization and politician-businessman collusion of media in Taiwan. The media reform group played a crucial role in this policy process, but seeking self-interest of other actors was the reason why they were willing to collaborate with the media reform group to support public broadcasting system. In the future, we still need the intellectuals to lead the people to be critical and self-conscious, developing further reform. The state, as an active regulator, should keep policy transparency and expand public participation.

Texte intégralRésumé :
Chapter Six examines how Guglielmo Marconi’s invention of the wireless telegraph in 1895, which eventually enabled the widespread use of radio broadcasting in the 1920s, challenged avant-garde movements like Futurism and Dada to develop new modes of print production and distribution that would allow them to communicate faster and farther. Instead of using a single magazine model to consolidate their movements, the Futurists and Dadaists relied on the wild proliferation of magazine titles in many different locations all at once (110 for the Futurists in Italy between 1910 and 1940; 175 for the Dadaists around the world between 1916 and 1926). In doing so, they made the magazine function like a wireless transmitter capable of sending and receiving information quickly, and, in the process, they established expansive communication networks that were not bound by the infrastructure of the postal system.

Texte intégralRésumé :
Building upon contextualization of the ACA as not a panacea, but instead a stage of progressive policy evolution, this chapter is the first of three chapters that sketches out a vision of health care reform that more completely satisfies the requirements of democratic citizenship and the possibility of social mobility that is essential to the preservation and advancement of political democracy. A basic premise of this chapter is that health care system finance reform logically (and in historical terms empirically) precedes health care system delivery reforms. The particular form of health care financing that is presented and then argued in this chapter is a hybridization of the social insurance approach to health care financing, subsidized by a vibrant voluntary insurance market. This approach takes into account both the principles of health care reform advanced in Chapter 4 and a pragmatic appreciation of the social and political context that has shaped the American liberal welfare state and continues to define its boundaries.

The death of the Confederate prison system, like the death of the Confederacy itself, was an uneven process across space and time. After the exchange at the Northeast Cape Fear River, the Confederacy acquired new Federal prisoners of war during the subsequent military campaigns of Schofield and Sherman. Recaptured prisoners from the great escapes of late February still populated county jails. One thousand prisoners returned to Andersonville in early April. A few days before Robert E. Lee surrendered the Army of Northern Virginia to Ulysses S. Grant, Colonel Henry Forno, the Confederate prison bureaucrat still in charge of the system in the Carolinas, wrote the new commissary general of prisoners, Brigadier General Daniel Ruggles, about building a new prison on a site eighteen miles from Columbia on the Charlotte & South Carolina Railroad line. “I am receiving small lots of prisoners and have no place to keep them but open fields,” Forno informed his superior. He estimated it would take him ten days to erect a stockade....

Texte intégralRésumé :
NRC Information Notice 98-31[1] describes a water hammer event that occurred at Columbia Generating Station. In this event, actuation of a Fire Protection System (FPS) led to voiding in a tall dead-ended riser with subsequent water hammer in the riser when the main fire pumps were activated. Due to the severity of the event, NRC requires that FPS with similar configurations at other nuclear power plants be analyzed for similar events. This paper describes an evaluation of two selected riser piping systems performed to quantify the susceptibility of the potential water hammer events in the FPS at a nuclear power plant. The FPS was modeled in a proprietary computer program, USLAM (Hydraulic Analysis Code), and selected operational scenarios (analysis cases) were analyzed to quantify the potential waterhammer loads (fluid forces). A tall riser piping system in the Reactor Building was chosen as a sample system for structural dynamic analysis. Based on the results of the sample system, it was concluded that the fire protection piping systems could experience piping stress far exceed the faulted allowable loads as allowed by the ASME/ANSI piping code. A cost-effective mitigation scheme was then proposed plan in paper ICONE65-82622[2] as Part 1 of this study with consideration only hydraulic loading where 11 vacuum breakers are to be installed at various locations of the FPS. The structural analyses discussed only piping stress in this paper and demonstrate for the effectiveness of the proposed mitigation scheme from the revised hydrodynamic loads. As the continuation of Ref. 2, the results from this study validate the acceptance of these two piping systems.

Texte intégralRésumé :
Terasen Gas Inc. (Terasen) operates a natural gas supply and distribution system situated within one of the zones of the highest seismic activity in Canada. The region encompasses significant areas underlain by marine, deltaic, and alluvial soil deposits, some of which are considered to be susceptible to liquefaction and large ground movements when subjected to earthquake ground shaking. Terasen undertook an assessment of seismic risks to its transmission and key intermediate pressure pipelines in the Lower Mainland in 1994 [1]. The seismic assessment focused on approximately 500 km of steel pipelines ranging from NPS 8 to NPS 42 and operating at pressures from 1900 to 4020 kPa. The 1994 risk assessment provided the basis for detailed site-specific assessment and seismic upgrade programs to retrofit its existing system to reduce risks to acceptable levels. While the general approach undertaken in 1994 remains technically sound, advancements have been made over the past 15 years in the understanding of earthquake hazards and their impact on pipelines. In particular, estimates of the earthquake ground shaking hazard in British Columbia as published by Geological Survey of Canada (GSC) have recently been updated and incorporated into the 2005 National Building Code of Canada (NBCC). In addition, empirical methods of estimating lateral spread ground displacements have been improved as new case-history information has become available. Given these changes, Terasen decided in 2009 to reexamine the seismic risk to Terasen’s pipelines. The scope of the updated seismic risk study was expanded over that in 1994 to include pipelines on Vancouver Island and the Interior of British Columbia. For regional assessments, estimates of lateral spread displacements are necessarily based upon empirical formulations that relate displacement to variables of earthquake severity (earthquake magnitude and distance), susceptibility to liquefaction (density, grain size, fines content), and topography (distance from a river bank or ground slope). Implementing empirical formulae with the results of probabilistic seismic hazard calculations is complicated by the fact that the empirical approach requires earthquake magnitude and distance, as a parametric couple, to be related to the ground shaking severity. However, but such a relationship does not exist in the estimates of mean or modal earthquake magnitude and distance disaggregated from a probabilistic seismic hazard analysis. This paper presents an overview of the approach to regional risk assessment undertaken by Terasen and discusses the unique approach adopted for determining lateral spread displacements consistent with the probabilistic seismic hazard analysis.

Texte intégralRésumé :
A number of proposed pipelines in western and northern Canada have highlighted critical path social risks associated with effectively engaging and consulting with impacted Aboriginal rightsholders along pipeline rights-of-way. Opening up new markets for Canada’s oil sands, shale and off-shore gas resources will require an expansion of the pipeline system in northern British Columbia, Alberta and the Northwest Territories. While navigating the regulatory approval process can be a formidable hurdle, a far greater challenge is how proponents manage the process of building relationships and consulting with affected Aboriginal communities. Failing to earn Aboriginal support for proposed projects can be a “show-stopper”. Exploration of new basins in Canada, driven by increased demand for energy in Asia, may compete with other land uses and constitutionally-protected rights and practices of indigenous peoples. Public, media and environmental response to new pipelines is often lead by the reaction of impacted communities. The task of identifying the social risks to a project, understanding the engagement process, fulfilling the regulatory consultation requirements of different jurisdictions, balancing impacts with benefits, managing issues and resolving disputes, communicating with the public and media effectively all require improved skills and approaches. The paper surveys the stakeholder engagement experience and differences in approaches for recently proposed major arctic gas and western oil pipeline projects, as well as pipelines to service Liquefied Natural Gas export facilities on the Pacific north coast, providing practical insights with possibly international application. Utilizing decision and risk analysis and scenario planning methodologies, applied to development of an Aboriginal engagement and consultation strategy, the paper examines how multi-billion dollar investments in new pipelines can be better secured by integrating stakeholder engagement into a project’s risk management design. With greater precision and improved approaches proponents can effectively manage social risks, reduce stakeholder conflict and associate project uncertainties.

Increasing demands on the productivity of complex systems, such as machine tools and their steadily growing technological importance will require the application of new methods in the product development process. This paper shows that the analysis of the simulation results from the simulation based mechatronic model of a complex system followed by a procedure that allows a better understanding of the dynamic behavior and interactions of the components. This paper will highlight the results of interaction between National Institute of Technology, (NITK) Surathkal, India and University of District of Columbia (UDC) in the area of Mechatronics and virtual testing. Mechatronics is a design philosophy, which is an integrating approach to engineering design. Through a mechanism of simulating interdisciplinary ideas and techniques, mechatronics provides ideal conditions to raise the synergy, thereby providing a catalytic effect for the new solutions to technically complex situations. Many real-world systems can be modeled by the mass-spring-damper system and hence considering one such system, namely Mechatronics Technology Demonstrator (MTD) is taken as the first example. MTD is a portable low cost, technology demonstrator that can be used for teaching mechatronics system design. The paper highlights design optimization of several mechatronic products using the procedures derived by the use of mass spring damper based mechatronic system. The second example is on web based virtual experimentation, where the experiment is conducted by remote triggering of Torsion Testing Machine. Remote triggered (RT) experimentation is a method of remotely controlling the laboratory equipment by an internet based system from a webpage. RT lab is an excellent way for the students to get access to expensive state of the art labs and equipment. The present work deals with the systematic approach of realizing a remote triggered experimentation on a horizontal torsional testing machine which can be triggered from a tablet PC or a laptop through an internet connection directed to the server computer system. RT lab algorithms are built in the server computer and the information and controls will be displayed on an html webpage where the experiment can be conducted. In this experiment the machine is remotely started through a command in the webpage which will be directed to the main server computer system from a wireless handheld internet enabled device such as laptops or tablet PCs and render the suitable graph of the experiment in the device. The experiment is completely in the control of the user. The person can either on/off the main equipment with the help of the device within the given slot of time and the data from the graph can be retrieved for further analysis. The first example uses a software platform of VisSim and the second example uses a software platform LabView. Although located in two different locations and countries, this paper examines the common mechatronics philosophy and the design approach used in modeling, simulation, optimization and virtual experimentation in building robust mechatronics product and procedures.

Texte intégralRésumé :
In the mid-1980s, the impact of three decades of uranium processing near rural Fernald, Ohio, 18 miles northwest of Cincinnati, became the centre of national public controversy. When a series of incidents at the uranium foundry brought to light the years of contamination to the environment and surrounding farmland communities, local citizens’ groups united and demanded a role in determining the plans for cleaning up the site. One citizens’ group, Fernald Residents for Environmental Safety and Health (FRESH), formed in 1984 following reports that nearly 300 pounds of enriched uranium oxide had been released from a dust-collector system, and three off-property wells south of the site were contaminated with uranium. For 22 years, FRESH monitored activities at Fernald and participated in the decision-making process with management and regulators. The job of FRESH ended on 19 January this year when the U.S. Secretary of Energy Samuel Bodman and U.S. Environmental Protection Agency Administrator Stephen Johnson — flanked by local, state, and national elected officials, and citizen-led environmental watchdog groups including FRESH — officially declared the Fernald Site clean of all nuclear contamination and open to public access. It marked the end of a remarkable turnaround in public confidence and trust that had attracted critical reports from around the world: the Cincinnati Enquirer; U.S. national news programs 60 Minutes, 20/20, Nightline, and 48 Hours; worldwide media outlets from the British Broadcasting Company and Canadian Broadcasting Company; Japanese newspapers; and German reporters. When personnel from Fluor arrived in 1992, the management team thought it understood the issues and concerns of each stakeholder group, and was determined to implement the decommissioning scope of work aggressively, confident that stakeholders would agree with its plans. This approach resulted in strained relationships with opinion leaders during the early months of Fluor’s contract. To forge better relationships, the U.S. Department of Energy (DOE) who owns the site, and Fluor embarked on three new strategies based on engaging citizens and interested stakeholder groups in the decision-making process. The first strategy was opening communication channels with site leadership, technical staff, and regulators. This strategy combined a strong public-information program with two-way communications between management and the community, soliciting and encouraging stakeholder participation early in the decision-making process. Fluor’s public-participation strategy exceeded the “check-the-box” approach common within the nuclear-weapons complex, and set a national standard that stands alone today. The second stakeholder-engagement strategy sprang from mending fences with the regulators and the community. The approach for dispositioning low-level waste was a 25-year plan to ship it off the site. Working with stakeholders, DOE and Fluor were able to convince the community to accept a plan to safely store waste permanently on site, which would save 15 years of cleanup and millions of dollars in cost. The third strategy addressed the potentially long delays in finalizing remedial action plans due to formal public comment periods and State and Federal regulatory approvals. Working closely with the U.S. and Ohio Environmental Protection Agencies (EPA) and other stakeholders, DOE and Fluor were able to secure approvals of five Records of Decision on time – a first for the DOE complex. Developing open and honest relationships with union leaders, the workforce, regulators and community groups played a major role in DOE and Fluor cleaning up and closing the site. Using lessons learned at Fernald, DOE was able to resolve challenges at other sites, including worker transition, labour disputes, and damaged relationships with regulators and the community. It took significant time early in the project to convince the workforce that their future lay in cleanup, not in holding out hope for production to resume. It took more time to repair relationships with Ohio regulators and the local community. Developing these relationships over the years required constant, open communications between site decision makers and stakeholders to identify issues and to overcome potential barriers. Fluor’s open public-participation strategy resulted in stakeholder consensus of five remedial-action plans that directed Fernald cleanup. This strategy included establishing a public-participation program that emphasized a shared-decision making process and abandoned the government’s traditional, non-participatory “Decide, Announce, Defend” approach. Fernald’s program became a model within the DOE complex for effective public participation. Fluor led the formation of the first DOE site-specific advisory board dedicated to remediation and closure. The board was successful at building consensus on critical issues affecting long-term site remediation, such as cleanup levels, waste disposal and final land use. Fluor created innovative public outreach tools, such as “Cleanopoly,” based on the Monopoly game, to help illustrate complex concepts, including risk levels, remediation techniques, and associated costs. These innovative tools helped DOE and Fluor gain stakeholder consensus on all cleanup plans. To commemorate the outstanding commitment of Fernald stakeholders to this massive environmental-restoration project, Fluor donated $20,000 to build the Weapons to Wetlands Grove overlooking the former 136-acre production area. The grove contains 24 trees, each dedicated to “[a] leader(s) behind the Fernald cleanup.” Over the years, Fluor, through the Fluor Foundation, also invested in educational and humanitarian projects, contributing nearly $2 million to communities in southwestern Ohio, Kentucky and Indiana. Further, to help offset the economic impact of the site’s closing to the community, DOE and Fluor promoted economic development in the region by donating excess equipment and property to local schools and townships. This paper discusses the details of the public-involvement program — from inception through maturity — and presents some lessons learned that can be applied to other similar projects.

Texte intégralRésumé :
The Geological Survey of Canada (GSC) undertook marine fieldwork onboard the Canadian Coast Guard Ship (CCGS) Vector to locate and map potential geohazards and geological features in the Salish Sea in the interest of public safety from August 11-18, 2021. This work was conducted under the Natural Resources Canada Marine Geoscience for Marine Spatial Planning (MGMSP) and the Public Safety Geoscience Programs. The GSC had observed multiple potential faults in existing data near Central Haro Strait, Stuart Channel, South of Hornby Island and near Cape Lazo through existing CHIRP and multibeam bathymetry data but required further data to quantify their activity and potential seismic risk (Barrie et al, 2021). In addition to fault activity, the GSC had detected numerous large underwater landslide deposits in Howe Sound and Saanich Inlet. The GSC required further data to constrain volumes and timing of slide activity. In English Bay the origin and evolution of a field of pockmarks was poorly understood. In Burrard Inlet, the survey required a better understanding of frequency of landslides as well as depth of sediment in order to understand natural sediment depositional rates. The research expedition included deep-tow system (DTS) sub-bottom surveys and multibeam water column and bathymetric surveys in each of these areas to better understand these marine geohazards and processes. Hydrographic surveys were completed by the Canadian Hydrographic Service (CHS) at night in Pylades Channel and near Point Grey to maximize use of ship time. Weather was good, seas were calm, and good quality data were collected. The data collected will be made publicly available and have the potential to contribute to building codes and to help communities in their decision-making and understanding of risks.

Visser, R., H. Kao, R. M. H. Dokht, A. B. Mahani et S. Venables. A comprehensive earthquake catalogue for northeastern British Columbia : the northern Montney trend from 2017 to 2020 and the Kiskatinaw Seismic Monitoring and Mitigation Area from 2019 to 2020. Natural Resources Canada/CMSS/Information Management, 2021. http://dx.doi.org/10.4095/329078.
Texte intégralRésumé :
To increase our understanding of induced seismicity, we develop and implement methods to enhance seismic monitoring capabilities in northeastern British Columbia (NE BC). We deploy two different machine learning models to identify earthquake phases using waveform data from regional seismic stations and utilize an earthquake database management system to streamline the construction and maintenance of an up-to-date earthquake catalogue. The completion of this study allows for a comprehensive catalogue in NE BC from 2014 to 2020 by building upon our previous 2014-2016 and 2017-2018 catalogues. The bounds of the area where earthquakes were located were between 55.5°N-60.0°N and 119.8°W-123.5°W. The earthquakes in the catalogue were initially detected by machine learning models, then reviewed by an analyst to confirm correct identification, and finally located using the Non-Linear Location (NonLinLoc) algorithm. Two distinct sub-areas within the bounds consider different periods to supplement what was not covered in previously published reports - the Northern Montney Trend (NMT) is covered from 2017 to 2020 while the Kiskatinaw Seismic Monitoring and Mitigation Area (KSMMA) is covered from 2019 to 2020. The two sub-areas are distinguished by the BC Oil & Gas Commission (BCOGC) due to differences in their geographic location and geology. The catalogue was produced by picking arrival phases on continuous seismic waveforms from 51 stations operated by various organizations in the region. A total of 17,908 events passed our quality control criteria and are included in the final catalogue. Comparably, the routine Canadian National Seismograph Network (CNSN) catalogue reports 207 seismic events - all events in the CNSN catalogue are present in our catalogue. Our catalogue benefits from the use of enhanced station coverage and improved methodology. The total number of events in our catalogue in 2017, 2018, 2019, and 2020 were 62, 47, 9579 and 8220, respectively. The first two years correspond to seismicity in the NMT where poor station coverage makes it difficult to detect small magnitude events. The magnitude of completeness within the KSMMA (ML = ~0.7) is significantly smaller than that obtained for the NMT (ML = ~1.4). The new catalogue is released with separate files for origins, arrivals, and magnitudes which can be joined using the unique ID assigned to each event.
