In this Very Short Introduction, Jacqueline Stedall explores the rich historical and cultural diversity of mathematical endeavour from the distant past to the present day, using illustrative case studies drawn from a range of times and places; including early imperial China, the medieval Islamic world, and nineteenth-century Britain--

"A car crashes in front of rookie PI Paige Holden's home. And suddenly, she finds one of her pro bono clients dying in her arms-from a gunshot wound. With her last breath, the woman whispers cryptic words into her ear and hands her a blood-smeared flash drive. Five years ago, State's Attorney Grayson Smith put a murderer behind bars. But when Paige Holden shares the flash drive with him, its contents cast doubts on the conviction-and lead him and Paige into a world of blackmail, dark secrets, and a decades-long string of murders. An investigation they'll survive only by trusting each other-and the truth."--P. [4] of cover.

"Megan Flynn thought she was falling in love. Cole Williams wasn't just handsome and passionate, he was one of the good guys. Or so she thought, until he arrested her brother--the only family she has left--for a murder she knows he couldn't have possibly committed. Now, with her heart broken and her brother's life hanging in the balance, Megan will risk everything to prove his innocence. Even if that means throwing herself into the path of a sadistic killer with a hauntingly familiar MO. Seattle Detective Cole Williams had given up on making Megan see reason where her brother is concerned. But when she insinuates herself in the most shockingly brutal case Cole has ever worked, he can't stand idly by. Plunged into a secret world where the city's elite indulge their darkest desires, Cole will do whatever it takes to bring down a madman who has made Megan his most coveted prey."--P. [4] of cover.

"This book provides a preview of emerging wireless technologies and their architectural impact on the future mobile Internet. The reader will find an overview of architectural considerations for the mobile Internet, along with more detailed technical discussion of new protocol concepts currently being considered at the research stage. The first chapter starts with a discussion of anticipated mobile/wireless usage scenarios, leading to an identification of new protocol features for the future Internet. This is followed by several chapters that provide in-depth coverage of next-generation wireless standards, ad hoc and mesh network protocols, opportunistic delivery and delay tolerant networks, sensor network architectures and protocols, cognitive radio networks, vehicular networks, security and privacy, and experimental systems for future Internet research. Each of these contributed chapters includes a discussion of new networking requirements for the wireless scenario under consideration, architectural concepts and specific protocol designs, many still at research stage"--
