地形生成算法

提出了通过读取单色BMP格式的等高线图产生三维地形的方法和使用OpenFlight API和分形算法生成三维地形的方法.第一种方法对应每一个高程生成一个或多个多边形,再把代表不同高度的多边形放置到对应的高度上,并从最低端的多边形开始,逐层向上一层多边形采用沿各顶点法线放样的方法生成地形三角形,这种方法适用于生成锥形山、丘陵等小面积地区的地形模型;第二种方法使用分形算法生成三维地形,这种算法生成地形速度快、逼真度高,适用于生成大面积的三维地形.

军装变奏曲

在一次探亲假中,正赶上哥哥搬家,几身叠得整整齐齐的军装摆在我眼皮底下,让人一瞅便感触良多.哥哥是1981年底参军的,在部队足足呆了十几个年头,如今早已复员的他居然还把军装保存着.闲谈中,哥哥说起了他走南闯北许多耐人寻味的美好回忆,然而最令他难忘的就是军装的变化.     

从王瑛的“铁骨柔情”说开去——三八妇女节有感

每年三八妇女节到来之时,我们总会情不自禁地想起一大串巾帼女杰:花木兰女扮男装,替父从军;刘胡兰面对顽敌的铡刀,面不改色,从容就义;红色娘子军为斗恶霸求翻身,转战椰林,所向无敌……她们不是男儿,胜过男儿,其志向坚定,其胸怀坦荡,其英勇顽强,其大义凛然,无不使人佩服、赞叹、崇敬。然而,在感叹之余,又觉得少了点什么——是否人们在赞美她们的"英雄气"时,忽略了她们的人情味、特别是女人味的一面呢?

Thomas Firth and Sons – Steelmakers to the Arms Industries. Part 2: Heavy Armaments

Firth’s were the first of the Sheffield steel makers to enter the field armaments. Their involvement with Colt has been outlined in an article in the journal of the Colt Collectors Association in America and their activities as steelmakers to the small-arms industries has been covered in a previous issue of this Journal. This article gives a brief overview of their involvement as manufacturers in the field of heavy armaments, being the first to make all-steel guns and their evolving role in the use of steel for ordnance, culminating in the displacement of wrought iron by the adoption of steel for ordnance manufacture by the Royal Gun Factory in the 1880s. It also highlights their development of stainless steel in this context.     

Casualty Rates of US Military Personnel During the Wars in Iraq and Afghanistan

Abstract

In Operation Iraqi Freedom, which ended in August 2010, nearly 3500 hostile deaths occurred among US military personnel and 32,000 more were wounded in action (WIA). More than 1800 hostile deaths occurred during Operation Enduring Freedom (in and around Afghanistan) through 2014 and about 20,000 were WIA. A larger proportion of wounded personnel survived in Iraq and Afghanistan than during the Vietnam War, but the increased survival rates were not as high as some studies have asserted. The survival rates were 90.2% in Iraq and 91.6% in Afghanistan, compared with 86.5% in Vietnam. The casualty rates varied between the conflicts in Iraq and Afghanistan and before, during, and after the respective surges. Amputation rates are difficult to measure consistently, but I estimate that 2.6% of all WIA and 9.0% of medically evacuated WIA from the Iraq and Afghanistan theaters combined resulted in the major loss of a limb. Elevated non-hostile death rates (including deaths due to accidents, illnesses, homicides, or suicides) resulted in about 220 more deaths in Iraq and about 200 more deaths in Afghanistan than would have been expected in peacetime among populations of the size deployed to those two conflicts.     

Women police in the Nigerian security sector

This article details the history and philosophy behind major changes in police tradition and organisation in Nigeria in 1955. Women in the Nigeria Police Force (NPF), influenced by their background as enforcers of societal norms, developed a type of social-work-oriented policing. Using primary and secondary sources of historical information, this article discusses the origin of women in the NPF, the specialised role of women in police work, and the changes that have been effected in the roles and functions of women in policing in Nigeria. Situated within the conceptual frameworks of patriarchy and gender, this article argues that gender biases impeded the incorporation of women into the police and, when eventually introduced, gender limitations constrained their roles, operations and activities.     

Unnecessary or unsung? The utilisation of airpower in Britain's colonial counterinsurgencies

Making extensive use of primary archival documents, this article seeks to explore whether airpower in three of Britain's most significant post-war colonial counterinsurgency campaigns, Malaya, Kenya and South Arabia, was an unnecessary part of British strategy, offering little useful military force due to the futility and strategic damage rendered by offensive bombardment, or whether airpower was indeed an unsung factor that provided operational flexibility through its effectiveness in a supply context, as well as its intelligence role in providing valuable aerial reconnaissance. In all three case studies the role played by the RAF in medical evacuations, in troop drops, in crop spraying during food-denial initiatives, and in providing ‘Voice Aircraft’ for the propaganda campaign, provide insights into an under-explored component of Britain's politico-military efforts in counterinsurgency in the 1950s and 1960s and suggests that the main strategic value of airpower in counterinsurgency, then and now, lies in its non-kinetic functions.     

Stopping Suicide Attacks: Optimal Strategies and Unintended Consequences

We study the behavior of defense spending in Switzerland over 1975–2001. Our main interest is in determining how neutrality in international affairs (non‐membership in military alliances) affects defense spending. We find that neutrality is associated with a perception of lower levels of external threat; hence it confers economic benefits in the form of a smaller defense burden. However, neutrality does not fully insulate a country from variations in the level of external threat in the global system as perceived by members of military alliances. Swiss defense spending has tracked very closely the spending trends – but at a lower average level – of the United States and other NATO countries. To the extent that post‐Cold War threats, such as international terrorism, materialize primarily in the context of existing security alliances, Swiss military spending patterns observed in 1975–2001 are likely to remain the same in the future.

Unraveling the violence in Kazakhstan

There were several high-profile violent incidents in 2011 in Kazakhstan, including several bombings, shootings that targeted police, and a protest turned clash that resulted in a number of deaths. Some of the perpetrators reportedly had links with radical religious groups. An overlooked aspect of the violence is how it is reported in Kazakhstan. There are active, competent media in Kazakhstan, which are largely unknown in the West. An examination of these incidents using the media in Kazakhstan can provide a unique insight into what took place. While Western sources quickly blamed radical religious groups with international connections, media in Kazakhstan have found that there are other reasons for the violence.
