无源RFID系统中推断式二进制搜索算法

在现有的RFID标准中,一般标签ID都由几个不同含义区间组成。针对这种特点,提出推断式二进制防碰撞算法：在识别每个区间段的ID时,利用某个特定读写器中的前缀库推断该区间段各个位的取值,以便减少待识别标签ID的位数。同时,通过调整参数u,可以对系统可靠性进行控制。仿真实验表明,在没有新前缀出现的情况下,推断式二进制防碰撞算法能够将QT算法的识别速度提高3倍、标签平均响应次数降低3／4。

Peace-building or structural violence? Deconstructing the aftermath of Nigeria/Cameroon boundary demarcation

ABSTRACT

There is a great conviction that the International Court of Justice’s ruling in 2002 on the Bakassi boundary dispute between Nigeria and Cameroon, and Nigeria’s decision to obey the ruling may have stopped a fierce inter-state war over the boundary. Indeed, many then ascribed to the whole boundary demarcation process as peacebuilding, disregarding the structural changes marked by the violence of forced migration. This article explores how the boundary delimitation has produced particular sorts of structural violence characterised by state neglect, loss of livelihoods and destitution. Thus, the article argues that although a full-blown war was avoided, the socio-economic conditions of the Nigerian populations on both sides of the border were not adequately considered and guaranteed as part of the peace-building agenda. It further argues that Nigeria, like many post-colonial states with the concentration of developments in major cities, neglects rural and border communities. Thus, the border communities accommodating the former Bakassi residents have further degenerated into ‘ill-governed’ spaces. This article uses structural violence as a framework to analyse the primary and secondary data to provide some deeper insights into the issues of violence being experienced by the local populations living on both sides of the demarcated border.     

Holmes’ front: constructing a new face of battle for America’s Civil War

ABSTRACT

In his seminal study of the changing nature of warfare between Agincourt and the Somme, military historian John Keegan proposed that future historians might consider combatants’ emotions in their assessments of the impact and nature of conflict. Recent years have witnessed the emergence of the history of emotions as an analytical approach, but rarely, if ever, is this directed toward the study of military history, far less the history of insurgencies and counter-insurgencies. This paper examines America’s civil war (1861–1865) as a case study of the ways in which an emotional history approach might illuminate not the physical experiences of but rather the immediate and longer-term reactions to counter-insurgency conflict through a focus on one specific individual, the future Supreme Court Justice Oliver Wendell Holmes, Jr. It proposes that Holmes, whilst not a man of the ranks, nevertheless can reveal the wider ramifications of civil war and its emotional impact, both individually and culturally. As a relatively limited internecine war, one not fought by professional armies but by volunteer forces, America’s civil war highlights the ways in which the soldier’s response points us toward the kind of emotional revolution that has, to date, mainly been located within the European nations.
