Описание: Both the Gloster Gladiator and the Fiat CR.42 Falco represented the peak in the development of the biplane fighter, which could trace its lineage back to World War I. However, by the time both aircraft entered service in the late 1930s, they were already obsolete. Nevertheless, they gave sterling service on all fronts in the Mediterranean and Africa in 1940-41.
Indeed, the CR.42 was the Regia Aeronautica's staple fighter in both North and East Africa, Greece and over Malta in 1940-41, during which time its pilots routinely fought British and Commonwealth squadrons equipped in the main with Gladiator biplanes. Some bitter dogfights were fought between these two types as the Allies attempted to gain control of the skies over North Africa, Greece and East Africa. Both types were flown in the main by highly experienced pre-war pilots, and this in turn made for some closely fought engagements.
The first known combat between the CR.42 and the Gladiator took place on 14 June 1940 over North Africa and the last engagement between the two types occurred on 24 October 1941 over the East African front.
Описание: In this breakthrough book, cofounder of acceptance and commitment therapy (ACT), Kirk Strosahl and two fellow ACT psychologists offer a brief, five-stage model to help you recognize, assess, and take advantage of the subtle shifts of awareness that occur during therapy to achieve the most effective intervention and successful treatment outcomes.
Описание: This book introduces therapists to the principles and practice of Focused Acceptance and Commitment Therapy, or FACT.

Описание: Optimisation, or mathematical programming, is a fundamental subject within decision science and operations research, in which mathematical decision models are constructed, analysed, and solved. The books focus lies on providing a basis for the analysis of optimisation models and of candidate optimal solutions for continuous optimisation models. The main part of the mathematical material therefore concerns the analysis and linear algebra that underlie the workings of convexity and duality, and necessary/sufficient local/global optimality conditions for continuous optimisation problems. Natural algorithms are then developed from these optimality conditions, and their most important convergence characteristics are analysed. The book answers many more questions of the form "Why?" and "Why not?" than "How?". We use only elementary mathematics in the development of the book, yet are rigorous throughout. The book provides lecture, exercise and reading material for a first course on continuous optimisation and mathematical programming, geared towards third-year students, and has already been used as such for nearly ten years. The preface to the second edition describes the main changes made since the first, 2005, edition. The book can be used in mathematical optimisation courses at any mathematics, engineering, economics, and business schools. It is a perfect starting book for anyone who wishes to develop his/her understanding of the subject of optimisation, before actually applying it.
