Jihad or qatal? Examining Al Qaeda's modus operandi

There is widespread acknowledgment that the modus operandi of jihadis affiliated with Al Qaeda and associated movements (AQAM) relies on brutal terror-inducing tactics which, more often than not, target Muslim and non-Muslim non-combatants. This article comparatively analyzes the AQAM modus operandi within the traditional stipulations of Islamic precepts with respect to waging jihad al saghir. The purpose is to glean whether or not such tactics such as suicide bombings, declaring fellow Muslim apostates in order to kill them, use of IEDs and EFPs to target civilians, constitute legitimate rules of engagement in jihad al saghir.     

The Telefunken Affairand the internationalisation of the Algerian War, 1957–59

Between 1957 and 1959 the West German company Telefunken and the Bonn government became prime targets in the French army's campaign against the Front de Libération Nationale's (FLN) efforts to establish communications networks. To the French military, the prevention of sales of Telefunken equipment to the FLN or its allies constituted a matter of strategic importance. To the Germans, it was an act of economic protectionism that exposed France's continued misgivings of Germany. The problem exerted a considerable strain between Paris and Bonn, and even threatened to harm German-Arab relations. The Telefunken affair thus highlights the Algerian war's international ramifications. It further reveals the responsibility of the French military in the internationalisation of that war.     

The winds of change: the transition from armed forces for peace to new missions for the Bundeswehr and its impact on civil–military relations

The debate on the civil–military gap and especially the TISS findings are viewed with a focus on Germany. After outlining the historical development of civil–military relations, the question of a civil–military gap is explored with data from 2001. The study finds similarities and differences in the attitudes of the civilian and the military population on several issues. Overall, there is a broad overlap of attitudes, yet differences do exist, especially on issues of foreign policy and things military. It is argued that at the beginning of the twenty-first century, civil–military relations in Germany are largely uncontested, but will become more strained.     

Local defence forces and counterinsurgency in Afghanistan: learning from the CIA's Village Defense Program in South Vietnam

Some scholars would have us believe that the distinctions between military and policing roles, methods and objectives have become increasingly blurred by the security demands of a post-Cold War and post-11 September global and domestic order. This article explores the current state of the police–military divide through a conceptual and case study analysis. It concludes that, in this case, there is some conflation occurring at a macro-level as international and domestic affairs have become increasingly indistinct, but the article also demonstrates that the actual ethos and practice of these agencies still differs strongly. Most importantly, the article argues that this distinction is in fact a very useful one in planning for future peace support operations     

Light weight HTPB-clay nanocomposites(HCN)with enhanced ablation performance as inhibition materials for composite propellant

In the present study,organically modified Montmorillonite clay with polar moiety,the Cloisite 30B,is used for preparation of Hydroxyl terminated polybutadiene(HTPB)-clay nanocomposites(HCN)by dispersion of nanoclay in polymer matrix under high shear mixing.The nanocomposites thus prepared are evaluated in composite propellants as inhibitor material for their functional utility.Several inhibition formulations containing 5 wt％-15 wt％of nanoclay,with or without the conventional filler Sb2O3,were prepared.All these formulations were evaluated for their physical,mechanical,thermal,and ablative properties.Ablation rate and density of the compositions containing Cloisite 30B is around 23％and 5％lower respectively in comparison of the base composition.Strain capability of these compositions is twofold higher than that of base composition.These compositions have also been evaluated for their smoke generation tendency by measuring infra red(IR)attenuation in the wavelength range 1.3 μm-5.6 μm and 8 μm-13 μm and thereby compared with the base composition.The corresponding results confirmed that the compositions containing Cloisite 30B as filler have much lower IR attenuation than compositions with conventional filler,Sb2O3.Replacement of 5％Sb2O3 by nanoclay showed 8％reduction in IR attenuation rate which further reduced to 16％on replacement of 15％of Sb2O3.Interfacial bonding of HCN based inhibitors is also comparable or even better than conventional inhibitors.Precisely,the nanoclay composites with Cloisite 30B as filler exhibit all desirable properties of an inhibitor.

磨合预处理对有机钼添加剂摩擦学性能的影响

采用MMW-1万能摩擦磨损试验机,考察了磨合预处理工况(时间、载荷)对两种有机钼添加剂在CF-4 15W-40柴油机油中抗磨减摩性能的影响。采用扫描电子显微镜和能谱仪分析了磨斑表面形貌和表面元素组成。结果表明,适当的磨合预处理可有效增强有机钼添加剂在柴油机油中的抗磨减摩性能,且经过磨合预处理的磨斑表面形貌较没有处理时平整,添加剂主要功能元素在摩擦表面的质量分数增加。     

Modeling the operation of multireservoir systems using decomposition and stochastic dynamic programming

Stochastic dynamic programming models are attractive for multireservoir control problems because they allow non‐linear features to be incorporated and changes in hydrological conditions to be modeled as Markov processes. However, with the exception of the simplest cases, these models are computationally intractable because of the high dimension of the state and action spaces involved. This paper proposes a new method of determining an operating policy for a multireservoir control problem that uses stochastic dynamic programming, but is practical for systems with many reservoirs. Decomposition is first used to reduce the problem to a number of independent subproblems. Each subproblem is formulated as a low‐dimensional stochastic dynamic program and solved to determine the operating policy for one of the reservoirs in the system. © 2006 Wiley Periodicals, Inc.
