<p>In recent years, the active anti-collision system using new technologies such as image target recognition between ship and bridge becomes a new research hotspot. Due to camera jitter, it is not easy to deeply mine the monitoring image data. This paper puts forward an anti-jitter algorithm to obtain the ship monitoring track in the sea area removing the camera jitter. It uses electronic image stabilization, sea-sky line anti jitter filtering, and other methods to process the on-site monitoring video, then compares the effect of each technique, and finally obtains high-quality ship tracking data. Through this method, a high-quality ship monitoring track in the bridge area can be obtained.</p>

Seismographic Network

&lt;p&gt;The decades long recordings of high-quality open data from the Global Seismographic Network have facilitated studies of earth structure and earthquake processes, as well as monitoring of earthquakes and explosions worldwide.&amp;#160; These data have also enabled a wide range of transformative, cross-disciplinary research that far exceeded the original expectations and design goals of the network, including studies of slow earthquakes, landslides, the Earth&amp;#8217;s &amp;#8220;hum&amp;#8221;, glacial earthquakes, sea-state, climate change, and induced seismicity.&amp;#160;&lt;/p&gt;&lt;p&gt;The GSN continues to produce high quality waveform data, metadata, and multiple data quality metrics such as timing quality and noise levels.&amp;#160;&amp;#160; This requires encouraging equipment vendors to develop modern instrumentation, upgrading the stations with new seismic sensors and infrastructure, implementing consistent and well documented calibrations, and monitoring of noise performance.&amp;#160;&amp;#160;&amp;#160; A Design Goals working group is convening to evaluate how well the GSN has met its original 1985 and 2002 goals, as well as how the network should evolve in order to be able to meet the requirements for enabling new research and monitoring capabilities.&amp;#160;&amp;#160;&amp;#160;&lt;/p&gt;&lt;p&gt;In collaboration with GEOFON and GEOSCOPE the GSN is also reviewing the current global distribution and performance of very broadband and broadband stations that comprise these three networks.&amp;#160; We are working to exchange our expertise and experience about new technologies and deployment techniques, and to identify regions where we could collaborate to make operations more efficient, where current efforts are overlapping or where we have similar needs for relocating stations.&amp;#160;&lt;/p&gt;

Detection Of Objects

Large amounts of high-quality image data are the basis and premise of the high accuracy detection of objects in the field of convolutional neural networks (CNN). It is challenging to collect various high-quality ship image data based on the marine environment. A novel method based on CNN is proposed to generate a large number of high-quality ship images to address this. We obtained ship images with different perspectives and different sizes by adjusting the ships’ postures and sizes in three-dimensional (3D) simulation software, then 3D ship data were transformed into 2D ship image according to the principle of pinhole imaging. We selected specific experimental scenes as background images, and the target ships of the 2D ship images were superimposed onto the background images to generate “Simulation–Real” ship images (named SRS images hereafter). Additionally, an image annotation method based on SRS images was designed. Finally, the target detection algorithm based on CNN was used to train and test the generated SRS images. The proposed method is suitable for generating a large number of high-quality ship image samples and annotation data of corresponding ship images quickly to significantly improve the accuracy of ship detection. The annotation method proposed is superior to the annotation methods that label images with the image annotation software of Label-me and Label-img in terms of labeling the SRS images.

IntroductionMobile health (m-health) technology has been growing rapidly in the last decades. The use of this technology represents an advantage, especially for reaching patients who otherwise would have no access to healthcare. However, many ethical issues arise from the use of m-health. Health equity, privacy policies, adequate informed consent and a competent, safe and high quality healthcare need to be guaranteed; professional standards and quality of doctor-patient relationship in the digital setting should not be lower than those set for in-person practice.AimsTo assess advantages and threats that may arise from the wide use of m-health technologies, in order to guarantee the application of the best medical practices, resulting in the highest quality healthcare.MethodsA literature search has been conducted to highlight the most pressing ethical issues emerging from the spreading of m-health technologies.ResultsFew ethical guidelines on the appropriate use of m-health have been developed to help clinicians adopt a professional conduct within digital settings. They focus on the need for professional associations to define ethical guidelines and for physicians to take care of their education and online behavior when using m-health technologies.ConclusionsThe rapid spreading of m-health technologies urges us to evaluate all ethical issues related to its use. It would be advisable to produce an ethical code for the use of these new technologies, to guarantee health equity, privacy protection, high quality doctor-patient relationships and to ensure that m-health is not chosen over traditional care for merely economic purposes.Disclosure of interestSG received honoraria or Advisory board/consulting fees from the following companies: Lundbeck, Janssen Pharmaceuticals, Hoffman-La Roche, Angelini-Acraf, Otsuka, Pierre Fabre and Gedeon-Richter.

AbstractThe very large development of home and domestic electronic appliances as well as portable device has led the microelectronics industry to evolve in two complimentary directions : “More Moore” with the continuous race towards extremely small dimensions hence the development of SoCs (System on Chip) and more recently a new direction that we could name “More than Moore” with the integration of devices that were laying outside the chips and here the creation of SiPs (System in Package).These two approaches are not in competition one with the other: the paper will show some examples of integrated nano systems that use several SoCs.The technology we have developed is called Silicon Based System in Package. The first products using this technology are now in volume production and used mainly in the field of wireless communications.This new technology relies on four pillars. Passive integration is the first. Very efficient and high quality factor capacitors and inductors have been integrated, allowing the creation of complete modules including active devices, filters and decoupling capacitors. High-density MOS capacitors with 1-1000 nF capacitance, and as high values as 25-250+ nF/mm2 specific capacitance have been fabricated in macroporous Si-wafers, containing over 1 billion macropores. Typically an ESR less than 100 mÙ and an ESL less than 25 pH were found for capacitors over 10 nF. This novel concept is an important step forward in improving the stability of power-amplifier modules by replacing conventional SMD technology.Whereas generations with capacitors density of up to 100 nF/mm2 will be using “conventional” materials and structures, the next steps in the roadmap will call for new 3D structures and materials such as high-k dielectrics.The second element is advanced packaging. New technologies, such as the assembly of Silicon chips onto other Silicon chips, also named “double flip chip” have been developed. This has been made possible thanks to the combination of the most advanced microbumping and die placement techniques. In addition to a tremendous reduction of size (up to a factor of 10 to 20) these techniques have also brought a better repeatability of system performance.The third element has been the development of design tools that allow a seamless system design for engineers used to IC design tools and flows. Our Design Environment allows co design of multiple technologies chips and their integration in a single system. This IC-like Design Environment has contributed a lot to the adoption of the technology.Testing is the fourth element and is one of the economical enablers of the technology. The key words are: “known good die”, RF test, system test? Some innovative RF probing and full on wafer subsystem test will be shown. Even though efficient test is not vital for the technical feasibility of this system integration, it becomes very quickly one of the most important enablers, especially when we deal with very high volumes of production. The conclusion of the paper will be an open door to the future. Some innovations like the integration of light or even energy storage inside our SiPs will be presented.

The importance of professional competence lies in the effective application of job-oriented knowledge and skills which guarantee one’s successful adaptation to the work. This study analyzes the perception of the importance of physical activity and sports (PAS) professionals’ competence in working with individuals with disabilities in Spain. As a descriptive quantitative study, face-to-face interviews were conducted through a survey to extract the data. The sample consisted of 214 PAS professionals working with people with disabilities. According to the results, the analyzed constituents of professional competence are important for adequate performance (&gt;65%), with the exception of competences of leadership and use of new technologies (&lt;50%). It was also found that the perceived importance of each element of professional competence varies according to age, experience and training. Based on the obtained results, the degree of importance of each constituent of professional competence and its implication for the access of people with disabilities to high-quality physical activity and sports services was determined.

This paper examines the involvement of sixteen undergraduate students across four disciplines in a practice-led research project to create the “Once Upon a Time in Palestine” XR documentary by exploring how they performed when given complex challenges, to create this novel and complex practice-led research project. The students were trained and mentored but also were trusted to work under minimal supervision. This created a high level of engagement with the expectation of high-quality output and presented the students with opportunities not afforded to them within the rigid structure of their academic programs. This paper examines the engagement of the students, and their willingness to learn new technologies and apply this learning to produce high quality output under tight deadlines with minimal supervision and the value of interdisciplinary collaboration across multiple fields of study. The paper concludes that while there was a steep learning curve, the students were able to achieve high-level engagement and produce professional results within the specified deadlines, using the latest technological advances in the field, while learning new skills outside their academic program and also enhancing the outcome of the successful project.
