This paper presents a stochastic jump di usion method for optimizing a Bayesian pos terior probability in segmenting range data and their associated re ectance images The algorithm works well on complex real world scenes indoor and outdoor which consist of an unknown number of objects or surfaces of various sizes and types such as planes conics smooth surfaces and cluttered objects like trees a...

In this paper jump transitions for the fluid model part in second order fluid stochastic Petri nets (FSPNs) are introduced. The extended formalism is defined, and the underlying partial differential equations are derived. With a jump a certain amount of fluid is added to a fluid place or taken out at once. This amount, the jump height, is sampled from a probability distribution. The dynamics of...

We begin by thinking about telephone calls. Suppose we are receiving a Poisson stream of calls. We start at height zero and whenever the telephone rings we jump upward a unit amount. Then our height, as a function of time, is a Poisson process. Let us generalize this. Suppose that we receive telephone calls randomly, but now each call gives us instructions: “Please jump an amount h”. If we star...

PURPOSE To investigate the relationship between physical fitness and team success in soccer, and to test for differences in physical fitness between different player positions. METHODS Participants were 306 male soccer players from 17 teams in the two highest divisions in Iceland. Just before the start of the 1999 soccer season, the following variables were tested: height and weight, body com...

BACKGROUND This study examined the outcomes of a vocational rehabilitation program (The Job Management Program, JUMP) for persons with psychotic disorders based on close collaboration between health and welfare services. METHODS Participants (N = 148) with broad schizophrenia spectrum disorders (age 18-65) were recruited from six counties in Norway. Three counties were randomized to vocationa...

Shock waves in molecular clouds should evolve into continuous or C-type structures due to the magnetic field and ion-neutral friction. We here determine whether and how this is achieved through plane-parallel numerical simulations using an extended version of ZEUS. We first describe and test the adapted code against analytical results, laying the necessary foundations for subsequent works on su...

A rapidly growing literature has documented important improvements in financial return volatility measurement and forecasting via use of realized variation measures constructed from high-frequency returns coupled with simple modeling procedures. Building on recent theoretical results in Barndorff-Nielsen and Shephard (2004a, 2005) for related bi-power variation measures, the present paper provi...

Background. The kinematics of a controlled functional task in female volleyball athletes may be an interesting area of study. Therefore, investigating if there are kinematic changes in a jump landing jump task among female athletes with low back pain (LBP) may help therapists and trainers better prevent and/or rehabilitate LBP in athletes. Objectives. The purpose of this study was to examine l...
