Analyzing Li-Fi Communication Benefits Compared to Wi-Fi

International Journal of Communications, Network and System Sciences 2022年第6期15卷 67-77页

Li-Fi, or known as light fidelity, is a new technology that could alleviate some network congestion for the ever-increasing internet of things (IOT). The patent for Li-Fi was created by german physicist Harald Haas in 2011 around visible light communication. The purpose of the following research includes the capabilities of Li-Fi Technologies and how the implementation of a Li-Fi network can improve network infrastructure. A main point is to highlight the advantages that Li-Fi technology brings to the table in comparison to traditional Wi-Fi networks like the increased bandwidth frequency, faster transmission speeds, as well as not being affected by network latency due to high traffic. Benefits that Li-Fi technologies provide to network infrastructure include the use of less energy, the need for fewer components to operate, as well as the simplicity of only needing a light source to provide high-speed internet traffic. Some of our research shows the implementation of these systems and how they can provide different benefits to different types of needs of the consumer. The research gave a complete idea about hybrid indoor systems based on Li-Fi and Wi-Fi that indicates how Li-Fi technology raises the possibilities to fulfill the technological demand in the future. Also, the part explained the security concerns of Li-Fi technology and we can consider this technology secure by updating some system protocols. At present day, Li-Fi lacks the infrastructure that Wi-Fi has, which makes replacement unideal. Rather, Li-Fi can be seen as complementary to Wi-Fi and used to improve current technology.

近年来,波兰电子游戏产业经历了快速发展,波兰本土游戏的企业投资正在不断增长,已经能够跟全球规模最大游戏公司进行竞争,同时波兰电子游戏市场消费的增长也十分迅速,而且波兰本土游戏开发公司将会成为全球电子游戏市场的领先者之一。波兰游戏公司开发的产品受到全球玩家的广泛欢迎,由CD PROJEKT RED制作的“巫师3:狂猎”电脑游戏持续占据着全球市场第一名的位置,迄今为止已经卖出了超过7百万份,现在仍在大卖。我们从波兰电子游戏产业的历史开始分析,这直接影响了产业当前的状态。当波兰的公司终于拿到了进军全球游戏市场的机会的时候,很多国外的游戏开发公司已经在国际市场上占据了领先和主导地位,因此只有实力最强和最高效的波兰公司可以在全球游戏市场的竞争中生存下来。随着时间的推移,波兰公司也意识到,其项目融资的最有利方式就是自己投资,而不是寻求行业内的投资者或出版商,他们后来声称大部分利润来自游戏销售本身。最后,根据波兰电子游戏现状调查报告的作者分析,波兰游戏开发公司成功的关键是实现就业的专业化。专门从事某特定游戏类别的公司比其他公司能够取得更大的成功。在另一方面需要注意的是,波兰的游戏开发公司也在不断面临着许多困难。最显著的问题是盗版盛行---这也是现有的所有游戏市场所面临的共同问题。更重要的是,根据波兰gameDev 2015年的调查结果,许多波兰游戏开发公司抱怨从波兰政府相关主管部门得不到足够的支持。这种支持对行业的稳定发展尤为重要,因为企业已经面临着要找到合格员工的问题。从长远来看,政府在教育方面的支持是可以帮助解决这个问题,通过促进波兰的高等教育机构之间的游戏开发教育是可以实现的。

Novel Automated Paced Fractionation Detection Algorithm for Ablating Ventricular Tachycardia

引用

Journal of Biomedical Science and Engineering 2016年第10期9卷 488-500页

作者： Divyanshu gupta Mohammad Hassan Shariat Madelaine Baetz-Dougan Javad Hashemi Selim Akl damian Redfearn Queen’s University Kingston Canada Kingston general Hospital Kingston Canada

Catheter ablation therapy has become a key intervention in treatment of ventriculartachycardia (VT). However, current fractionation mapping methods used to isolate the ablation targets in VT patients are done manually, and are therefore time consuming. They also have limited success rates (50% recurrence rate within 2 years). We present a fully automated fractionation detection algorithm for patients with VT which expands on previously defined fractionation features and which substantially decreases associated study times. Paced electrogram signals were collected from six patients during electrophysiologic study according to a modified paced electrogram fractionation analysis protocol. Data were exported and analyzed offline using custom written software. Electrograms from right ventricular pacing catheter were used as reference. Surface electrograms, along with ventricular geometry and relative catheter locations, were used to identify physiological interference and physiologically irrelevant features. A total of 264 electrograms, collected from a roving catheter, were manually and automatically annotated for fractionation as defined by three features: conduction time (CT), electrogram duration (ED), and number of deflections (ND). Of these, 60 were selected manually to have no discernable features and were successfully discarded by our algorithm;yielding a specificity of 100%. Of the remaining 204, 16 were erroneously discarded by our algorithm;yielding a sensitivity of 92.16%. A comparison between annotations showed correlations of 0.98, 0.97, and 0.94 for AL, ED, and ND respectively.

A prospective, open label, 24-week trial of methylcobalamin in the treatment of diabetic polyneuropathy

Journal of Diabetes Mellitus 2012年第4期2卷 408-412页

作者： Jacqueline C. Dominguez Arlene R. Ng Ludwig F. damian Institute for Neurosciences St. Luke’s Medical Center Quezon City Philippines

Introduction: Vitamin B complex has been used for peripheral neuropathy for a long time and continues to be part of current practice despite lack of strong evidence for its use and its non-inclusion in treatment guidelines. Objective: To determine the clinical and neurophysiological effects of 1500 μgm/day of oral methylcobalamin among subjects with diabetic polyneuropathy. Methodology: We conducted a prospective, open-label study on adult diabetic subjects with polyneuropathy who were given 1500 μgm/day of oral methylcobalamin over 24-weeks. The primary outcome measure was the Toronto Clinical Scoring System (CSS) and secondary measures were Subjective Impression of Change, Clinicians Impression of Change and neurophysiological parameters. Results: Out of forty eight subjects, thirty seven completed treatment and twenty one agreed to have repeat neurophysiologic study post-treatment. At the end of treatment, there was a significant decline in the Toronto CSS score (p g improvement. This was observed across all stages of severity and in any duration of diabetes whether more or less than 10 years. The symptoms that improved compared to baseline and that did not emerge over the course of 24 weeks were tingling (p gns of impaired position (P gnificant improvement was seen in the secondary outcomes (both p=0.06) except for ulnar nerve amplitude and distal latency. Conclusion: This 24-week open label study demonstrated that symptoms of diabetic polyneuropathy significantly improved among subjects given methylcobalamin 1500 μgm/day and new symptoms did not emerge over the 24 week observation period. Larger controlled trials are needed to corroborate these findings.

摄影师damian Chrobak自2004年开始游走于美国、英国、德国、波兰、新西兰等国家的超级大都市，坚持用黑白影像记录街头故事。与多数人的感受不同，大都市对他来说，不是被现代科技所累、疲于奔命，而是相反，充满了丰富的层次，可以有最多样性的观察，让拍摄灵感受到极大的激发。“街头摄影需要摄影师具备极其敏感的心灵和社会洞察力。我按下快门的瞬间，看起来似乎都是不被人注意的、无关紧要的时刻，但恰恰是司空见惯的生活里，隐藏着一些关于人生的永恒真相。”
