A survey on rocky shore mollusks was conducted in some bays of Socorro Island during February and May 1991 and March 1992.Specific richness and composition were analyzed for all expeditions.Relative density and frequency were analyzed only for the last two.The Importance Value Index (IVI) and Jaccard and Morisita similarity indexes were also calcul
Simulation-based business model innovation process for business-to-business contexts
Innovating service-oriented business models in industrial business-to-business (B2B) contexts presents a complex and risky endeavor.Recently, System Dynamics (SD) modelling and simulation has been suggested as a tool for prototyping and experimentation in business model innovation (BMI).However, knowledge of how to best utilise SD in BMI is scarce.
Retroperitoneal lipoma arising from the urinary bladder
Retroperitoneal benign lipomas are extremely rare and represent about 2.9% of all primary retroperitoneal tumors.About 80% of the tumors in the retroperitoneal cavities are malignant neoplasms.We experienced a case of a retroperitoneal lipoma simulating an ovarian mature cystic Hearer teratoma.A diagnosis was correctly made by magnetic resonance im
Unsupervised Image Classification Based on Fully Fuzzy Voronoi Tessellation
High noise resistance and high boundary fitting accuracy have always been the HR Board goals of image classification.However, the two mutually constrain each other, making it extremely difficult to reach equilibrium.To deal with this problem, the unsupervised image classification algorithm based on fully fuzzy Voronoi tessellation is proposed.It ex
