SAVE ENERGY Company – Smart Energy Saver Product


In our day today life, we are enjoying the modern inventions in technology to the extreme. Although the inventions are increasing rapidly on one hand, on the other hand the energy usage is also getting on higher for utilising these technical inventions. And moreover, the educational institutions, industries, house apartments are fully dependent on electricity. Thus, as a result we face the problems of global warming, climatic changes, and high electricity bills and so on. In addition, the press media, internet and televisions are broadcasting the news of saving the energy for future. Apparently, it has become an important issue that we came up with maintaining an earth hour to lessen the carbon dioxide emission in the atmosphere. So, by considering this significant issue our company members came up with a concept of building a product for controlling the energy consumption.

Our product will be built for monitoring and controlling the amount of energy usage in houses. Our product mainly involves a ‘Master Device’ which will be able to monitor and control the energy consumption of each electronic equipment used in our houses. The Master Device will hold the information of which device is being operated and at what time. Along with this, the plugs and fuses are improved to ‘Smart Plugs’ and ’Smart Fuses’ by attaching sensors and relays to do the sensing and switching operations. The Master Device also has a wifi module inside it, to communicate with the smart fuses and plugs for activating or deactivating the electricity to particular electronic equipment. The user will also be able to control the Master Device remotely for fixing the duration for a particular device to be switched on or switched off. Thus, a Smart Energy Saver product to save the energy for future.

Security Architecture and Services for the Bitcoin System


Executive Summary:

Bitcoin is a digital currency which is based on P2P network and open source software. It is a virtual currency without any control by any centralized organization. New Bitcoins are issued by lots of specified algorithms. The whole Bitcoin network utilizes the distributed database to verify and record all the transactions through the nodes in the P2P network in which the double spending is prevented. No person or organization is able to control Bitcoin based on a decentralized P2P network and algorithm. The cryptographic functions of Bitcoin are designed to allow only the real Bitcoin owner to pay and transfer, and ensure the anonymity and marketability.

The purpose of this thesis is to analyze the security architecture and services for the Bitcoin system and describe of all the features and infrastructures of the whole Bitcoin network. A whole establishment demo including wallet client, mining server with GUI and mining client is implemented. Further improvement will be suggested and recommended for the system.

Surface 屏幕截图

Surface 当你需要分享你Surface里的精美图片给朋友们时,截图是一个非常需要的功能。同样的,微软的Surface不需要安装下载任何的第三方的应用程序,你可以直接使用其内嵌的截图功能,截取出精美的照片并且它会直接的保存在照片文件夹里。


  •  Surface


  1.  就目前所知,有三种方法,Surface可以进行截图功能。 第一种:利用组合键。 第二种:利用功能键。 第三种:利用APP。
  2.  第一种:WIN+down音量键。 利用按住Windows键同时按下“降低音量”按钮。 默认的保存位置为:C:\Users\\My Pictures\Screenshots
  3.  第二种:利用键盘FN+WIN+空格键 (需要按住 Fn 键才能使用 F1 – F12 键,否则是 F1 – F12 上对应的 Windows 8 特殊功能。)
  4.  第三:利用snipping tool 在app中搜索并打开该工具,即可使用。


  •  该组合键适用于Surface RT和Surface Pro。
