Over-pressurized drums: Their causes and mitigation

Sealing of Rotary Drums for Operation Under Pressurized Conditions

Uplift, denudation, and their causes and constraints over geological timescales

We define uplift and denudation, then review the basic principles underlying the mechanisms for producing uplift, and the methodologies used to quantify the geological timescale denudation history of uplifted regions. Uplift is represents work done against gravity, and does not necessarily lead immediately to rapid denudation. The causes of uplift can be categorised according to the principal d...

Delays in Construction Projects: Causes and Mitigation

Drums and Curve Descriptors

In this paper we present a new physically motivated curve descriptor based on the solution of Helmholtz’s equation. The descriptor satisfies the six principles set by MPEG-7: it has a good retrieval accuracy, it is compact, it can be applied in general contexts, it has a reasonable computational complexity, it is robust and provides an hierarchical representation of the curve from coarse to fin...

Sickness Assessment of Abbasid Caliphs and Their Causes of Death

Despite the peak of medical knowledge in the Abbasid period, the presence of famous medical families in the Abbasid court, translation and writing of medical works, attention to nutrition and health in the court of the Abbasid caliphs, the expectation of long life and quality was created for the Abbasid caliphs. However, all these possibilities were not used much by the caliphs, and if they had...
