今年家电行业的走势与去年相反，上半年家电下乡和节能补贴相继收官，提前释放了一些市场需求；与去年同期相比，行业前期的基数也较低，这使得行业增长率十分可观。国内外众多品牌今年均携手旗下全线大、小家电“重装上阵”，与往年不同的是，这些家电都有了智能互联的趋势。中国家电协会分析指出，目前随着中国大众消费者的消费能力不断提高，仅能满足基本功能需求的家用电器已经不能满足消费者的要求。

随着我国网络购物行业的稳定发展，小家电网络购物也发展迅速。2012年，小家电网络购物跻身于中国网购用户消费支出最高的品类Top10，成为继服装鞋帽品类、IT产品类、通讯产品类等之后第八大品类。此外，小家电成为2012年中国女性网购用户常购商品之一。本研究的目的是基于iUserTracker的网民网购行为精准数据，呈现小家电网购用户的触媒习惯、广告态度、购物态度和购物行为，力图为小家电商家在广告投放、营销推广等战略决策提供数据支持。

A circuit breaker is an electrical switch that is used to protect an electric circuit from short-circuiting and overloading. If there is an overloading problem, the circuit breaker detects it and the supply is turned off automatically. A fuse is used to prevent current overload and consists of a wire inside the component that heats up and melts disconnecting the circuit from the overloading power source and thereby protecting all the electrical and electronic devices in the circuit. A relay is a switch that opens and closes a circuit electronically. It controls one circuit through opening or closing contacts in another circuit.

An e-cigarette/e-vaping device/personal vaporizer/e-nicotione delivery system is a type of electronic inhaler used to simulate to tobacco smoking.The Global E-cigarette market is growing at a rapid rate across the globe. In 2013, the market was dominated by North America, which was followed by Western Europe and the APAC region. The US was the largest market for e-cigarettes and it was followed by Germany and Russia. The market is expected to witness complex marketing dynamics due to the expected changes in the socio-political and legal scenario across the world during the period 2013-2018. The Global E-cigarette market is expected to grow at a CAGR of 30.56 percent during the forecast period.

Commercial aircraft lighting systems are classified into exterior lighting systems, interior lighting systems, and emergency lighting systems. Landing lights are used in night landing operations by aircraft. Position lights are also known as navigation lights. These lights are placed on the wingtips (red on left wingtip, green on right wingtip) and on the tail of an aircraft. Anti-collision lights are used to illuminate the important parts of an aircraft such as the rudder (vertical tail of the aircraft), fuselage (body of the aircraft), and the wingtips of the aircraft. A red beacon is used on the rudder, while white strobes are used on the wingtips. Cockpit lights help pilots to view important switches and instruments. Cabin lights are used to illuminate the aircraft cabin. Emergency lights include interior and exterior lights that are battery powered. They are not directly connected to the main electrical system of an aircraft.

The Global Portable Air Conditioning System market is growing at a significant rate across North America and Europe. The market was dominated by North America, followed by Europe in 2013. The market in the APAC region and the ROW is currently growing at a slow rate due to inability of portable air conditioning systems to produce cooling effects proportional the extreme climatic conditions. The Global Portable Air Conditioning System market is expected to grow at a CAGR of 12.56 percent during the period 2014-2018.The Global Portable Air Conditioning System market is growing at a significant rate across North America and Europe.

A DMFC is a subcategory of fuel cells that uses methanol as the primary fuel. One of the major advantages of using methanol as a fuel in DMFCs is that the fuel cells can operate without the need to first convert the fuel into hydrogen gas. DMFCs consist of two electrodes that are connected with the external circuit; this allows the conversion of energy through chemical reaction between methanol and air or oxygen, which is then directly converted into electrical energy. The common operating temperature for DMFCs is 50-120 degree Celsius. Due to its low operating temperature, the energy density is high, which is generally preferred for portable applications.
