Power Line Communications for Smart Cities

為了解決plc的問題，作者 這樣論述：

This book shows the importance of Power Line Communications (PLC) technology to improve and solve the limitations and drawbacks of other communications channels by integrating with these communications channels. Furthermore, PLC technology creates a new hybrid communications channel that can lead

to reliable and strong communications systems capable of meeting today’s communications challenges for smooth, reliable and high data rate transmission systems able to cope with the challenges facing smart cities. Active researchers on PLC technology contribute to this book by emphasising the impor

tance of this technology in building future smart cities. This book is subdivided into three major thematic parts: Part I: Communications Channels: This part is an overview from a theoretical and a practical perspective presented in the form of survey of the three major communications channels: Powe

r Line Communications (PLC), Visible Light Communications (VLC) and Wireless Communications (WCC) channels.Part II: Hybrid Communications Systems: This part presents examples of how the new emerging technology combines the three communications channels into specific applications. The new hybrid cha

nnels are discussed and examples of applications are presented.Part III: PLC and its Applications: This part is reserved for smart homes, smart grid and smart cities, making use of the new hybrid technology with PLC as the backbone.

Property Damage

為了解決plc的問題，作者2 Temple Gardens 這樣論述：

Over the last few years there has been an emerging specialism for property damage. Property damage frequently leads to losses other than the cost of repairing the damage, giving rise to disputes about the extent to which those losses can be recovered from insurers. Insurance companies have increased

the number of claims they defend in court and these cases have become progressively more technical, hence the number of cases now heard by the TCC (Technology and Construction Court). These cases range from multi-national construction and utility projects to domestic property matters such as floods

, fires, explosions and subsidence. Practitioners are advising across the spectrum of clients from the largest insured loss arising from the London Riots in 2011, to losses for owner managed companies where making a recovery from insurers was essential to the survival of their business.The claims co

mmonly raise insurance questions, frequently in the construction or product liability context, and they often involve claims against construction and other professionals. Practitioners need expertise across fields of insurance, construction, product liability and professional liability. Property dam

age claims typically require the involvement of expert witnesses in relation to liability such as forensic scientists, as well as experts on the standards to be expected of professionals and contractors. The claims also usually require the involvement of experts to deal with quantum (forensic accoun

tants to assess financial losses, quantity surveyors and valuers to assess the cause and extent of property damage losses). 2 TG on Property Damage is a comprehensive practitioners' text covering the full spectrum of issues and case law such as: - Goodlife Foods Ltd v Hall Fire Protection Ltd 2017]

EWHC 767 (TCC)- Wheeldon Brothers Waste Ltd v Millennium Insurance Co Ltd 2017] EWHC 218 TCC- Great Lakes Reinsurance (UK) SE v Western Trading Limited 2016] EWCA 1003- WH Newson Holding Limited v IMI Plc & Delta Limited 2016] EWCA Civ 773 2 Temple Gardens are highly respected for property dam

age work, and as well as handling major cases, also offer regular training seminars to solicitors and insurance industry professionals. The set is instructed in a broad range of property damage work handling everything from major fire and flood cases to challenging construction disputes and matters

concerning damage arising from defective products.

利用動態遷移最佳化雲儲存的讀取效能

為了解決plc的問題，作者陳磊恩 這樣論述：

通常來說，在雲端上磁碟區的效能與大小相關。磁碟區的大小決定磁碟區的基準效能。然而雲端服務提供者如亞馬遜，微軟等為了應對不同時間資料存取頻率的不平等，提出了 I/O 額度的概念。I/O 額度代表當需求超出基準效能時，磁碟區可用來爆發大量 I/O 的可用頻寬。當需求低於磁碟機的基準效能時，I/O 額度就會累積。磁碟區愈大，基準效能層愈高，累積 I/O 額度的速度愈快。當累積的 I/O 額度愈多，需要更多效能時，磁碟區能爆量超過基準效能的時間愈長，表現也愈佳。為了保持系統運行在有 I/O 額度的狀態，之前有其他人提出了可以透過複製資料的方法，並比較成本和收益證明可行性。然而純粹的資料複製會導致程式

中斷，並且消耗掉 I/O 額度，為解決這兩個問題，我們提出了動態遷移，藉由快照和記憶體暫存，以及延遲暫存轉存，讓中斷時間最小化，並保持中斷其間的頻寬。我們將動態遷移的方法應用在天氣預測系統 WRF 上，和沒有 I/O 額度的方法相比，加快了運行時間 332 %
