The effect of structure on the solution times of minimum cost transportation and multi-echelon network flow problems

Researchers require benchmark test problems to evaluate the speed of computer codes designed to solve minimum cost network flow problems. To date, the only universally available test problems developed for that purpose are randomly generated. In practice, however, real-world network problems solve faster than random network problems. This thesis examines the effect on solution time resulting from applying structure, produced through simulation of real-world phenomena, to test networks. An efficient computer code, VSGEN, is developed which generates structured transportation and multiechelon networks. Various types of structure, including unit flow cost, network topology and arc capacity, reduced the time required to solve the test networks an average of 26%, when using a primal network simplex solver, GNET.http://archive.org/details/effectofstructur00bonwLieutenant, United States NavyApproved for public release; distribution is unlimited

Joseph Goebbels: Expressionist Dramatist as Nazi Minister of Culture

The young Joseph Goebbels, caught up in the heady mix of ideas and ideals permeating German artistic circles during and after the First World War, expressed both his convictions and his confusions through writing plays. None of these deserve much attention as serious drama, but all shed light on the ideological development of the future Nazi Minister of Culture. While also developing an argument on the wide relationship between Expressionism and modernism, David Barrett here traces that relationship in Goebbels' plays, as also the evolution of an ideology that remained equivocal in its aesthetic--the necessary condemnation of 'degenerate' art tinged with a lingering admiration, epitomized in the infamous exhibition of 1937

Cephalohematomas, an occult nidus for infection and inflammation: A case report and review of the literature

Background: Cephalohematomas (CH) are benign neonatal fluid collections that arise between the periosteum and skull due to birth trauma, and usually resolve spontaneously without intervention. CH may rarely become infected. Case description: The authors report a case of sterile CH requiring surgical evacuation in a persistently febrile neonate treated with intravenous (IV) antibiotics for Escherichia coli urosepsis. Diagnostic tap of the CH yielded no pathogens, but given the persistence of fevers, surgical evacuation was performed. The patient demonstrated clinical improvement postoperatively. Conclusion: A systematic review of literature was conducted through a MEDLINE search using the keyword cephalohematoma. Articles were screened for cases of infected CH and their subsequent management. Clinicopathological characteristics and outcomes of the present case were reviewed and compared to those in the literature. Infected CH were reported in 25 articles describing 58 patients. Common pathogens included E. coli and Staphylococcal species. Treatment included a course of IV antibiotics (10 days-6 weeks) and often included percutaneous aspiration (n = 47) for diagnostic and therapeutic purposes. Surgical evacuation was performed in 23 cases. To the authors\u27 knowledge, the present case is the first documented report in which evacuation of a culture-negative CH resulted in resolution of the patient\u27s clinical symptoms of sepsis that persisted despite appropriate antibiotic treatment. This suggests that patients with CH should be evaluated through diagnostic tap of the collection if there are signs of local or persistent systemic infection. Surgical evacuation may be indicated if percutaneous aspiration does not result in clinical improvement
