Rappiotaide - saksalaista ekspressionismia Vexi Salmen kokoelmasta -kirja esittelee maassamme harvinaisen grafiikkakokoelman. Sanoittaja, kirjailija ja taidekeräilijä Vexi Salmi on puolisonsa Katri Wanner-Salmen kanssa syventynyt saksalaiseen sotienväliseen ekspressionismiin usean vuosikymmenen ajan. Salmen kokoelman taiteilijat ovat kahden sodan sukupolvea. He kokivat ensimmäisen maailmansodan kauhut, näkivät nälkää ja haavoittuivat fyysisesti ja henkisesti. Natsi-Saksassa näiltä taiteilijoilta kiellettiin opetustyö, heidän teoksensa julistettiin rappiotaiteeksi, poistettiin museoista ja usein myös tuhottiin. Moni ekspressionistista tyylisuuntaa edustanut taiteilija lähti maanpakoon, tuli karkotetuksi tai joutui kuulusteluihin ja keskitysleireille. Saksalainen ekspressionistinen taide kehittyi jo ennen ensimmäistä maailmansotaa ja sen kukoistusaikaa oli 1920-luku. Maalausten ja grafiikan voimakas ilmaisu, vahvat värit ja primitiiviset ääriviivat sekä raju aihepiiri erottavat sen muusta ajan eurooppalaisesta taiteesta. Kirja kertoo Vexi Salmen intohimoisesta paneutumisesta saksalaiseen ekspressionismiin ja luo syventävän katsauksen aikakauden taiteeseen, poliittisiin käänteisiin ja taiteilijakohtaloihin. Kirjoittajina ovat Vexi Salmen ja Katri Wanner-Salmen lisäksi Dr. Peter Barth sekä FT Seppo Zetterberg.

Despite the often-unimaginable horrors of war, bonds of family and friendship can hold us together… Peter Barth was born in Hamburg during the Second World War. Sound and Fury explores war-time memorabilia, tape-recorded conversations, photographs and letters, to uncover amazing stories about his three closest families during the war. All three families lived close by in Hamburg. Towards the end of July 1943, the RAF bombed the city, creating an enormous firestorm and killing 45,000 people. The families survived and were scattered around Europe. His father and cousin were sent to the siege of Leningrad, both returned severely wounded. The Koschel family moved to Krakow. When the Red Army moved west, they had to flee. They came close to being caught in the RAF firestorm of Dresden. Meanwhile the Barths were refugees in a pretty village close to Bergen-Belsen, the horror of which only emerged when it was liberated by the Allies. Just north of there, the Cap Arcona (with Uncle Adam on board) was anchored in the Bay of Lübeck with two other ships, after rescuing thousands of refugees and wounded soldiers. The SS took command and packed the ships with thousands of concentration camp victims. The day before the German forces surrendered, RAF planes bombed and sank them. No one knows why.

A logic view of 0-1 integer programming problems, providing new insights into the structure of problems that can lead the researcher to more effective solution techniques depending on the problem class. Operations research techniques are integrated into a logic programming environment. The first monographic treatment that begins to unify these two methodological approaches. Logic-based methods for modelling and solving combinatorial problems have recently started to play a significant role in both theory and practice. The application of logic to combinatorial problems has a dual aspect. On one hand, constraint logic programming allows one to declaratively model combinatorial problems over an appropriate constraint domain, the problems then being solved by a corresponding constraint solver. Besides being a high-level declarative interface to the constraint solver, the logic programming language allows one also to implement those subproblems that cannot be naturally expressed with constraints. On the other hand, logic-based methods can be used as a constraint solving technique within a constraint solver for combinatorial problems modelled as 0-1 integer programs.
