Modern enterprises increasingly use the workkow paradigm to prescribe how business processes should be performed. Processes are typically modeled as annotated activity graphs. We present an approach for a system that constructs process models from logs of past, unstruc-tured executions of the given process. The graph so produced conforms to the dependencies and past executions present in the lo...

In this paper we introduce a new algorithm for segmentation of medical images of any dimension. The segmentation is based on geometric methods and multiscale analysis. A sequence of increasingly blurred images is created by Gaussian blurring. Each blurred image is segmented by locating its ridges, decomposing the ridges into curvilinear segments and assigning a unique label to each, and constru...

We prove that the Willmore ow can drive embedded surfaces to self-intersections in nite time.

We analyze numerically macroscopic models of crowd dynamics: classical Hughes model and the second order model being an extension to pedestrian motion of the Payne-Whitham vehicular tra c model. The desired direction of motion is determined by solving an eikonal equation with density dependent running cost function standing for minimization of the travel time and avoidance of congested areas. W...

Background: Obesity is a major risk factor for cardiovascular disease, type 2 diabetes, high blood pressure, sleep apnea, psychological issues, some musculoskeletal conditions, and cancers. The aim of the study to evaluate correlation between BMI non-alcoholic fatty liver disease (NAFLD). Method: research was conducted cross-sectionally in NAFLD patients who were treated at RSUP H Adam Malik Me...

A recent study was performed to assess the morphometric variation of otoliths Decapterus kurroides collected in northern Sulu and southern Sibuyan seas delineating fish stocks. Seven otolith descriptors (otolith length, OL; height, OH; weight OW; area, OA; perimeter, OP; ellipticity, EL; aspect ratio, AR) demonstrated a significant positive correlation with length six (rectangularity, RE; squar...

Topological transitions in core-annular ow of oil and water are described. Drops of one liquid are suspended in the second liquid and transported through a pipeline under a pressure gradient. We examine the merging of an array of drops in this twouid ow. Larger drops are found to merge and the ow undergoes a topological transition to core-annular ow. In core-annular ow of two liquids, one liqui...

E!ective business process management necessitates a consistent information #ow between the participants in the process, the smooth integration of the #ow of work, the timely sharing of data and information during the planning and implementation phases and harmonious support for the collaborative aspects of work. The recent trends in the development of advanced work#owmanagement systems and tech...

Understanding the evolutionary role of gene ̄ow is pivotal to the conservation of endangered populations. Gene ̄ow can be enhanced through population translocations that are conducted to maintain genetic variation and combat the negative consequences of inbreeding depression (two of the major concerns in the conservation of subdivided or isolated populations). While researchers have given exten...

Data ow and mutation testing are two powerful white box testing techniques for unit-level software testing. Unfortunately, they cannot be completely compared on an analytical basis, for example, mutation is incomparable on an inclusion basis with most data ow criteria. This paper shows that mutation includes the All-defs data ow criterion, but is incomparable with other data ow criteria, and pr...
