The process capability analysis is a crucial activity to evaluate if the process outcome meets the design specifications. Classically, such analysis is performed by verifying the in-control condition of the process and evaluating suitable capability indices, by assuming the process in-control steady-state condition. However, the in-control period of the process characterizes only a part of the ...

With the development of biotechnology, high-throughput studies on protein-protein, protein-gene, and gene-gene interactions become possible and attract remarkable attention. To explore the interactions in dynamic gene regulatory networks, we propose a single-index ordinary differential equation (ODE) model and develop a variable selection procedure. We employ the smoothly clipped absolute devia...

We present techniques for maintaining subgraph frequencies in a dynamic graph, using data structures that are parameterized in terms of h, the h-index of the graph. Our methods extend previous results of Eppstein and Spiro for maintaining statistics for undirected subgraphs of size three to directed subgraphs and to subgraphs of size four. For the directed case, we provide a data structure to m...

Let T be a string with n characters over an alphabet of bounded size. The recent breakthrough on compressed indexing allows us to build an index for T in optimal space (i.e., O(n) bits), while supporting very efficient pattern matching [2, 4]. This paper extends the work on optimal-space indexing to a dynamic collection of texts. Precisely, we give a compressed index using O(n) bits where n is ...

We provide a unified framework using which we design scalable dynamic adaptive video streaming algorithms based on index based policies (dubbed DASIP Fig. 2) to maximize the Quality of Experience (QoE) provided to clients using video streaming services. Due to the distributed nature of our algorithm DAS-IP, it can be easily implemented in lieu of popular existing Dynamic Adaptive Streaming over...

With the ubiquity of large-scale graph data in a variety of application domains, querying them effectively is a challenge. In particular, reachability queries are becoming increasingly important, especially for containment, subsumption, and connectivity checks. Whereas many methods have been proposed for static graph reachability, many real-world graphs are constantly evolving, which calls for ...

In this article, the dynamic stability of a mobile manipulator using ZMP compensation is considered. A unified approach for the two subsystem is formulated using redundant scheme. First, to conserve the dynamic stability of the system, we define the performance index for the redundant system using ZMP(Zero Moment Point). This performance index represents the stability of the whole mobile manipu...

This paper describes a stochastic dynamic programming based approach to solve Sensor Resource Management (SRM) problems such as occur in tracking multiple targets with electronically scanned, multi-mode radar. Specifically, it formulates the SRM problem as a stochastic scheduling problem and develops approximate solutions based on the Gittins index rule. Novel results include a hybrid state sto...

Dynamic attributes are attributes that change continuously over time making it impractical to issue explicit updates for every change. In this paper, we adapt a variant of the quadtree structure to solve the problem of indexing dynamic attributes. The approach is based on the key idea of using a linear function of time for each dynamic attribute that allows us to predict its value in the future...
