We introduce an entropic segmentation algorithm and apply it to decompose the financial sequences into compositionally homogeneous domains. To probe more about the nature of the financial time series, we investigate the statistical properties of the segment from the view of segmentation position and segment length first. We reveal some important and interesting conclusions and information hidde...

in this paper, we study l1 -solutions of the following two-direction poly-scale refinement equationwe prove that the vector space of all l1 -solutions of the above equation is at most one-dimensional andconsists of compactly supported functions of constant sign. we also show that any- l1 solution of the aboveequation is either positive or negative on its support under a special assumption. with...

recently a method has been developed to decouple the equations of motion for multi-rigid body systems. in this paper, the method is first studied, then the equations of motion for a planar two degree-of-freedom robot with flexible joints are carried out using lagaranges equations and kanes equation with congruency transformations. finally, the results obtained from both methods are throroughly ...

Objective- To evaluate the some serum biochemical alterations after urinary diversion with colonic segment.Design- Experimental in vivo study.Animals- five adult healthy mixed breed dogs of both sexes weighing between 25-40 kg. Procedures- In this approach, fifteen centimeters of the descending colon with preservation of its mesenteric vessels was resected and this segment longitudinally was op...

Satisfactory damping of power oscillations is an important issue to be addressed when dealing with the angle stability of power systems. This phenomenon is well-known and observable especially when a fault occurs. To improve the damping of oscillations in power systems, supplementary control laws can be applied to existing devices. These supplementary actions are referred to as power oscillatio...

Abstract Paroxysmal brain state changes, such as microsleep events in drivers, are presumably subcortically induced and accompanied by cortical processes. This raises questions of how stable persistent the processes that can be observed with EEG real time. For this purpose, recordings four night-driving simulation studies including 79 subjects used to analyze large time window temporal offset s...

Performance prediction of checkpointing systems in the presence of failures is a well-studied research area. This paper makes three small contributions to this research area. First, we show how to apply the concept of availability from reliability theory as a useful metric for checkpointing systems. Second, we study the average availability of uniprocessor checkpointing systems, using the libck...
