军队院校文化管理模式初探

管理现代化是一所大学成功办学的基本标志。军队院校文化管理理论的提出是时代发展的必然要求。军队院校实施文化管理的核心内容及基本策略就是建设好、使用好自己的特色文化,为此,管理者应注意处理好有为管理与无为管理、柔性管理与刚性管理、部门主管与分工合作、硬件投入与软件提升四个方面的关系。

英语写作中的母语负迁移现象分析——以“合训”学员写作为例

在二语习得过程中,学习者的母语使用会直接影响第二语言的习得,并对其起到积极促进或消极干扰作用。以“合训”学员英语写作中出现的典型常见错误为例,从词汇、句法、语篇三个层面分析母语负迁移对军校学员英语写作造成的影响,指出在英语教学中要积极引导学员的汉语正转移,消除学员的负迁移,不断提高英语教学的效果。     

Supply licensing when the manufacturer strategically commits to invest in R&D

This article proposes a strategic reason for a proprietary component supplier to license her technology to a competitor or a manufacturer: her anticipation of the manufacturer's strategic commitment to invest in research and development (R&D). We address this phenomenon with a game theoretic model. Our results show that the manufacturer's full commitment to invest in R&D enables the supplier to license, sell a larger quantity through the supply chain, and charge lower prices. These results are robust to the type of demand uncertainty faced by the manufacturer within the class of increasing generalized failure rate distributions. © 2014 Wiley Periodicals, Inc.

亚轨道飞行器试验运载火箭的射程控制

运载火箭试验靶场就是用于火箭发射试验的专门场区,包括陆域、海域、空域等。靶场安全问题比较复杂、涉及范围广,火箭进入外层空间前不允许穿越外国领域或必须保证距国境线有一定的安全距离,其残骸落区不允许在外国领域。在我国,受到国土范围限制,又要实现洲际运载火箭全程飞行试验的要求,实际中通常采取"高弹道"、"低弹道"等特殊弹道的飞行试验来代替全程飞行试验的策略。通过对两类特殊亚轨道飞行器的飞行试验火箭的弹道特点描述,开展射程控制分析,研究基于我国国境进行亚轨道飞行试验的靶场安全控制方法。射程控制,对于低弹道可以采用控制俯仰程序角速度方法,而对于高弹道可以采用控制俯仰程序角方法。

A search game on a cyclic graph

There is a finite cyclic graph. The hider chooses one of all nodes except the specified one, and he hides an (immobile) object there. At the beginning the seeker is at the specified node. After the seeker chooses an ordering of the nodes except the specified one, he examines each nodes in that order until he finds the object, traveling along edges. It costs an amount when he moves from a node to an adjacent one and also when he checks a node. While the hider wishes to maximize the sum of the traveling costs and the examination costs which are required to find the object, the seeker wishes to minimize it. The problem is modeled as a two‐person zero‐sum game. We solve the game when unit costs (traveling cost + examination cost) have geometrical relations depending on nodes. Then we give properties of optimal strategies of both players. © 2004 Wiley Periodicals, Inc. Naval Research Logistics, 2004.     

Optimal pricing for a short life‐cycle product when customer price‐sensitivity varies over time

Technology products often experience a life‐cycle demand pattern that resembles a diffusion process, with weak demand in the beginning and the end of the life cycle and high demand intensity in between. The customer price‐sensitivity also changes over the life cycle of the product. We study the prespecified pricing decision for a product that exhibits such demand characteristics. In particular, we determine the optimal set of discrete prices and the times to switch from one price to another, when a limited number of price changes are allowed. Our study shows that the optimal prices and switching times show interesting patterns that depend on the product's demand pattern and the change in the customers' price sensitivity over the life cycle of the product. © 2012 Wiley Periodicals, Inc.

The Chinese and Asian impact on Russian nuclear policy

Asia, where nuclear powers already interact (including North Korea), exerts a growing influence on the thinking and policy underlying Russia's current and future nuclear (and overall defense) posture. China's rise is forcing Russia into a greater reliance on strategic offensive weapons and tactical nuclear weapons. These in turn will reinforce its opposition to US missile defenses, not only in Europe but also in Asia. Russia must now entertain the possibility of nuclear use in regional conflicts that would otherwise remain purely conventional. It cannot be postulated blindly that nuclear weapons serve no discernible purpose other than to deter nuclear attacks by other nuclear powers. The strategic equation in Asia and in the Russian Far East convincingly demonstrates the falsity of this approach. Nuclear weapons will be the essential component of Russia's regional defense policy if not of its overall policies – and this also includes contingencies in Europe.     

遥控武器站总体结构参数优化研究

为减小遥控武器站炮口扰动以提高射击精度,建立了遥控武器站部分机构参数化三维模型、有限元模型和刚柔耦合动力学模型。基于多学科集成优化软件ModelCenter进行了系统集成,以减小炮口扰动为目标,建立了遥控武器站总体结构参数优化模型。采用多目标遗传算法对总体结构参数进行了优化,优化后炮口振动状况明显改善,与位移相关的起始撼动和与速度相关的起始扰动分别较原方案降低了17.05%和19.04%。
