In wireless multihop networks, the objective of the broadcast scheduling problem is to find a conflict free transmission schedule for each node at different time slots in a fixed length time cycle, called TDMA cycle. The optimization criterion is to find an optimal TDMA schedule with minimal TDMA cycle length and maximal node transmissions. In this paper we propose a two-stage hybrid method to ...

This paper describes the GlottHMM speech synthesis system for Blizzard Challenge 2012. The aim of the GlottHMM system is to combine high-quality vocoding and detailed prosody modeling in order to produce expressive, high quality, synthetic speech. GlottHMM is based on statistical parametric speech synthesis, but it uses a glottal flow pulse library for generating the excitation signal. Thus, it...

A new hybrid-model for BCI probe is derived . This model is built based on the probe's internal structure without refinements, and by carrying out just one electrical measurement for the reflection coefficient, so that it can be generalized and used in studying the effect of layout parameters in the aim of improving the probe high frequency performance, which helps the developer in design stage...

This article addresses a multi-stage flowshop scheduling problem with equal number of unrelated parallel machines. The objective is to minimize the makespan for a given set of jobs in the system. This problem class is NP-hard in the strong sense, so a hybrid heuristic method for sequencing and then allocating operations of jobs to machines is developed. A number of test problems are randomly ge...

In the last decade the hybrid procedure has emerged as an alternative stage I palliation in neonates with hypoplastic left heart syndrome (HLHS). This review discusses the historical aspect, surgical and interventional techniques, current outcomes and future direction of this procedure. Hybrid palliation yields equivalent but not superior stage I palliation survival and comparable 1-year surviv...

Limited-entry fracturing (LEF) technology is a widely used method to realize the simultaneous propagation of multiple fractures in horizontal wells. The key this create high perforation friction maintain treatment pressure wellbore and uniform fluid entry multi-fractures; however, cannot be effectively maintained due serious erosion effect. Considering that current laboratory studies mostly sma...

Ships play the major role in bulk transportation and they need their special energy system. This paper proposes a stochastic programing method for optimal sizing of a hybrid ship power system with energy storage system (ESS), photovoltaic power (PV) and diesel generator. To account for uncertainties, in this study a two-stage stochastic mixed-integer non-linear programing is used to model the o...

A 67-year-old man complicated with back pain. The computed tomography (CT) scan showed an extended thoracoabdominal aneurysm. We successfully performed a three-stage hybrid repair using the visceral-renal debranching technique. For the first stage operation we performed Y-grafting with the debranching technique to create a distal landing zone. Then, for the second stage operation, we performed ...

Using a two-stage growth curve analysis, change over time in performance on tests in the Halstead-Reitan Battery and Average Impairment Rating (AIR) was assessed for 53 individuals who varied in age and health status. In the first stage of the analysis, estimated slope and intercept values were calculated for each individual by regressing longitudinal data points on time. In the second stage, e...
