Entropy Maximisation and Open Queueing Networks with Priority and Blocking.Kouvatsos, Demetres D., Awan, Irfan U. January 2003 (has links)
No / A review is carried out on the characterisation and algorithmic implementation of an extended product-form approximation, based on the principle of maximum entropy (ME), for a wide class of arbitrary finite capacity open queueing network models (QNMs) with service and space priorities. A single server finite capacity GE/GE/1/N queue with R (R>1) distinct priority classes, compound Poisson arrival processes (CPPs) with geometrically distributed batches and generalised exponential (GE) service times is analysed via entropy maximisation, subject to suitable GE-type queueing theoretic constraints, under preemptive resume (PR) and head-of-line (HOL) scheduling rules combined with complete buffer sharing (CBS) and partial buffer sharing (PBS) management schemes stipulating a sequence of buffer thresholds {N=(N1,¿,NR),0<Ni¿Ni¿1,i=2,¿,R}. The GE/GE/1/N queue is utilised, in conjunction with GE-type first two moment flow approximation formulae, as a cost-effective building block towards the establishment of a generic ME queue-by-queue decomposition algorithm for arbitrary open QNMs with space and service priorities under repetitive service blocking with random destination (RS-RD). Typical numerical results are included to illustrate the credibility of the ME algorithm against simulation for various network topologies and define experimentally pessimistic GE-type performance bounds. Remarks on the extensions of the ME algorithm to other types of blocking mechanisms, such as repetitive service blocking with fixed destination (RS-FD) and blocking-after-service (BAS), are included.

Terrorism, war and international law: the legality of the use of force against Afghanistan in 2001Williamson, Myra Elsie Jane Bell January 2007 (has links)
The thesis examines the international law pertaining to the use of force by states, in general, and to the use of force in self-defence, in particular. The main question addressed is whether the use of force, which was purported to be in self-defence, by the United States, the United Kingdom and their allies against al Qaeda, the Taliban and Afghanistan, beginning on 7 October 2001, was lawful. The thesis focuses not only on this specific use of force, but also on the changing nature of conflict, the definition of terrorism and on the historical evolution of limitations on the use of force, from antiquity until 2006. In the six chapters which trace the epochs of international law, the progression of five inter-related concepts is followed: limitations on the resort to force generally, the use of force in self-defence, pre-emptive self-defence, the use of forcible measures short of war, and the use of force in response to non-state actors. This historical analysis includes a particular emphasis on understanding the meaning of the 'inherent right of self-defence', which was preserved by Article 51 of the United Nations' Charter. This analysis is then applied to the use of force against Afghanistan which occurred in 2001. Following the terrorist attacks of 11 September, the US and the UK notified the United Nations Security Council of their resort to force in self-defence under Article 51. Each element of Article 51 is analysed and the thesis concludes that there are significant doubts as to the lawfulness of that decision to employ force. In addition to the self-defence justification, other possible grounds for intervention are also examined, such as humanitarian intervention, Security Council authorisation and intervention by invitation. This thesis challenges the common assumption that the use of force against Afghanistan was an example of states exercising their inherent right to self-defence. It argues that if this particular use of force is not challenged, it will lead to an expansion of the right of self-defence which will hinder rather than enhance international peace and security. Finally, this thesis draws on recent examples to illustrate the point that the use of force against Afghanistan could become a dangerous precedent for the use of force in self-defence.

The Limits of Fire Support: American Finances and Firepower Restraint during the Vietnam WarHawkins, John Michael 16 December 2013 (has links)
Excessive unobserved firepower expenditures by Allied forces during the Vietnam War defied the traditional counterinsurgency principle that population protection should be valued more than destruction of the enemy. Many historians have pointed to this discontinuity in their arguments, but none have examined the available firepower records in detail. This study compiles and analyzes available, artillery-related U.S. and Allied archival records to test historical assertions about the balance between conventional and counterinsurgent military strategy as it changed over time.
It finds that, between 1965 and 1970, the commanders of the U.S. Military Assistance Command, Vietnam (MACV), Generals William Westmoreland and Creighton Abrams, shared significant continuity of strategic and tactical thought. Both commanders tolerated U.S. Army, Marine Corps, and Allied unobserved firepower at levels inappropriate for counterinsurgency and both reduced Army harassment and interdiction fire (H&I) as a response to increasing budgetary pressure. Before 1968, the Army expended nearly 40 percent of artillery ammunition as H&I – a form of unobserved fire that sought merely to hinder enemy movement and to lower enemy morale, rather than to inflict any appreciable enemy casualties. To save money, Westmoreland reduced H&I, or “interdiction” after a semantic name change in February 1968, to just over 29 percent of ammunition expended in July 1968, the first full month of Abrams’ command. Abrams likewise pursued dollar savings with his “Five-by-Five Plan” of August 1968 that reduced Army artillery interdiction expenditures to nearly ten percent of ammunition by January 1969. Yet Abrams allowed Army interdiction to stabilize near this level until early 1970, when recurring financial pressure prompted him to virtually eliminate the practice. Meanwhile, Marines fired H&I at historically high rates into the final months of 1970 and Australian “Harassing Fire” surpassed Army and Marine Corps totals during the same period. South Vietnamese artillery also fired high rates of H&I, but Filipino and Thai artillery eschewed H&I in quiet areas of operation and Republic of Korea [ROK] forces abandoned H&I in late 1968 as a direct response to MACV’s budgetary pressure. Financial pressure, rather than strategic change, drove MACV’s unobserved firepower reductions during the Vietnam War.
