The report analyzes the sunglasses market based on design of sunglasses available in the market, that include aviator/pilot, round, cat eye, oval, square, rectangle, and others. The report also analyzes the sunglasses market in accordance with frame material that includes acetate, metal, injected, and others.

Powder coating technology was introduced in the 1940s. In the powder coating technique, the metal product was coated with dry powder instead of conventional liquid paints. By the late 1950s, powder coatings were used to coat pipes to protect the metal from corrosion and used in electric motor parts for insulation. They were also flame sprayed onto the metal substrate. The most common method for the application of powder coatings was the fluidized bed process, in which the heated parts were dipped into wet powder and fluidized by air. These particles of powder come in contact with heated metal parts and form a smooth layer on the metal substrate.

A taxi, also known as a cab, is a type of vehicle for hire with driver used by a single passenger or small group of passengers, often for a shared or non-shared ride. A taxi or a cab conveys passengers between locations of their choice. This differs from public transport, as here the pick-up and drop-off locations are decided by the customer, and not by the service provider. There are various distinct forms of taxi, which includes limousines, hackney carriages, and private hire vehicles including passenger car, motorcycle, scooters, minivan, van, buses & coaches, auto rikshaw, bicycles, and tricycles. Taxi services are typically provided by automobiles, but in some countries various human-powered vehicles such as rickshaw or pedicab, animal-powered vehicles such as the Hansom cab and water taxies or air taxies are also used. Customers can book a ride via text message request, phone calls, or by going directly service provider’s physical location.

Note sorters are used as sorting units that facilitate the management of notes for cash-intensive businesses. The note sorter machine helps banks reduce the human efforts as well as reduces different types of error in sorting and counting of cash. In addition, it provides different benefits to end users that include reduction in operational expenses, less risk of internal theft occurring during the sorting and counting processes, faster processing of bank procedures, and decline in financial losses.

Envelope tracking is a power supply technique that is used to adjust the converter voltage to improve the efficiency of a power amplifier, which is used in wireless systems. In envelope tracking technique, RF signal’s amplitude envelope is tracked and the bias voltage is adjusted according to the results in amplitude. This helps in operating power amplifier with maximum efficiency at any instantaneous power level. The recent cellular communications, such as W-CDMA, HSPA+, and LTE, operate signal waveforms with more extreme “peaks” and “valleys”, unlike GSM, which maintains continuous waveform throughout the operation. Recent cellular technologies experience continuous deflection in waveforms; hence, the requirement of envelope tracking technique is required to bring out maximum efficiency.

Digital transformation in BFSI is a set of methodologies, tools and processes that is used by modern companies to improve their operational activities and to enhance their sales. The key objective of digital transformation in BFSI is to automate, and digitize processes in the banking & fintech organizations and to streamline critical process of the organization. Numerous benefits are associated with digital transformation in BFSI, which include enhance security features, better risk management process, automation of repetitive tasks and others. The key factors that drive the growth of the global digital transformation in BFSI market include increase in adoption of digital technology by various banks and surge in need of digital services among the fintech to improve the customer experience. In addition, increase in customized IT solutions for specific banking need positively impacts the growth of the market. However, high implementation and maintenance cost of digital technology and security & privacy concerns related to data theft and cyber-attacks is expected to hamper the market growth. On the contrary, increase in adoption of advance technology such as AI and machine learning among the companies, is expected to offer remunerative opportunities for the expansion of the global market during the forecast period.

加拿大与美国在钢铝产品、乳制品以及软木贸易存在贸易争端。过去一年，加美两国签署了新版北美自由贸易协定，即《美国-墨西哥-加拿大协定》（United States-Mexico-Canada Agreement，USMCA），乳制品和钢铝贸易争端也暂告一段落，而软木贸易争端则成为加拿大批准USMCA的主要障碍。本文首先介绍加美钢铝、乳制品和软木贸易争端的由来和焦点问题。其次，本文采用开放经济政治学（Open Economy Politics，OEP）以及欧特利（Thomas Oatley）的分析框架，分析加拿大和美国政府在钢铝、乳制品及软木贸易方面的政策偏好与利益。

俄罗斯能源战略的东向策略通过几个大型项目得到体现，主要是向亚洲各国，特别是向中国供应俄罗斯的能源产品。俄中在能源领域的技术创新合作的主要方向是共同参与在俄新的油气化工产业群的建设和进行共同管理；参与构建东部片区全球性电力能源体系；原煤系统深加工合作；在俄东部地区建设“绿色能源”项目，以保障隔绝偏远地区消费者的能源供应。

本报告以国际上经常使用的媒介Facebook和Twitter为载体，阐述了国际社会化媒体中用户个体以及用户群体在信息接触和信息扩散中所扮演的角色及起到的作用。研究揭示了网络评论在社会事件传播中的效果和多元网状社交空间对网络评论发展的影响。

伦敦交通局2018年7月发布“步行行动计划”，提出将伦敦建成全球最适宜步行城市的愿景。该计划首先调查了参与步行的群体，梳理出了阻止人们步行的八大障碍，分析了促进步行潜能的因素以及步行的潜在群体。该计划随后提出了步行的阶段目标，并为伦敦的不同区域制定了不同的策略，并提出具有针对性的行动计划。行动计划包括四大领域，分别是建造和管理适合步行的街道、进行步行导向的规划设计、整合步行和公共交通、引领文化变革。该计划对于我国大城市提升对步行适宜性有着重要的借鉴意义。
