In particular, we focus on wireless network- ing between cars. One of many technologies that make road traffic safer and more efficient is the Virtual Traffic Light （VTL） system, which is able to coordinate the traffic flow at intersections without the need for physical lights. VTL takes a leading vehicle at an inter- section and uses it to control the traffic lights. We developed algorithms for leader election and traffic light computation in realistic ve- hicular networking scenarios. Our key contribution is the extension of this algorithm to support arbitrary intersection layouts. We in- vestigated the proposal in synthetic and realistic scenarios. The results show that, overall, VTLs use network resources efficiently and positively influences driving experience. It performs better than stationary traffic lights for a low to medium network load. We also identify potential optimizations to deal with high network load and to improve fairness.展开更多

It is a literary dialect which attempts to suggest the speech of the Bolton （Lancashire） area. As a complete research of this dialect is beyond the scope, I aim to analyze some deviant spellings which affect words containing some RP long vowels/i：/, /c：/,/3：/and/a：/. A historical insight is provided to indicate the possible origins of the pronunciations suggested by the author. The findings of this study reveal important data. According to the EDD, most of the pronunciations here suggested are present in Lancashire. Many of them are also present in other northem counties, but barely in Scotland and the southem part of England. On the other hand, Graham Shorrocks in his study of the Boiton area does not provide similar pronunciations in all cases. As for the words here presented, Joseph Wright attests most of them in the EDD. Nevertheless, the EDD and the web search are fruitless in other words.展开更多
