|Optimal sounding sequences which satisfy a certain autocorrelation property are useful for fast channel estimation techniques which are based on non-iterative channel sounding methods. In this paper, we study optimal sequences consisting of complex symbols with constant magnitude. An indirect sequence construction method is derived by considering the phase diierence between sequence symbols. O...
Experiments and computer simulations are carried out to investigate phase separation in a granular gas under vibration. The densities of the dilute and the dense phase are found to follow a lever rule and obey an equation of state. Here we show that the Maxwell equal-areas construction predicts the coexisting pressure and binodal densities remarkably well, even though the system is far from the...
Traditionally, access to structurally defined complex carbohydrates has been very laborious. Although recent advancements in solid-phase synthesis have made the construction of complex oligosaccharides less tedious, a high level of technical expertise is still necessary to obtain the desired structures. We describe the automated chemical synthesis of several oligosaccharides on a solid-phase sy...
The objective conditions and the obstacles of collection resources construction in present college libraries are analyzed in this paper. The overview of CALIS and its third-phase project is introduced. The approach of virtual library collection construction of university libraries by using CALIS cloud platform is explored.
The Split Delivery Vehicle Routing Problem (SDVRP) is a relaxation of the Capacitated Vehicle Routing Problem (CVRP) where customers may be assigned to multiple routes. A new construction heuristic is developed for the SDVRP and computational results are given for thirty-two data sets from previous literature. With respect to the total travel distance, the construction heuristic compares favora...
A microfluidic platform for the construction of microscale components and autonomous systems is presented. The platform combines liquid-phase photopolymerization, lithography, and laminar flow to allow the creation of complex and autonomous microfluidic systems. The fabrication of channels, actuators, valves, sensors, and systems is demonstrated. Construction times can be as short as 10 min, pr...
The Linac Coherent Light Source (LCLS) is a SASE xray Free-Electron Laser (FEL) project presently under construction at SLAC [1]. The injector section, from drive-laser and RF photocathode gun through first bunch compressor chicane, was installed in fall 2006. Initial system commissioning with an electron beam has recently been completed. The second phase of construction, including second bunch...
Almost every paper I have ever read on infrastructure finance focuses on the achievement of what market practitioners believe is the Holy Grail of infrastructure finance. As PwC (2013) has stated in a recent publication, ‘[a] logical infrastructure project debt market would use short-term bank debt markets e.g. construction finance, with refinancing into the long-term institutional markets as s...
Built environment carbon reduction strategies materialize predominantly in city-level greenhouse gas (GHG) management, where new residential development appears as one of the key instruments. However, city-level assessments are often incapable of producing data at a community or neighborhood level and thus they may heavily underestimate the emissions from new construction. This paper explores t...
Asymmetric quantum error-correcting codes are quantum codes defined over biased quantum channels: qubitflip and phase-shift errors may have equal or different probabilities. The code construction is the Calderbank-ShorSteane construction based on two linear codes. We present families of toric surfaces, toric codes and associated asymmetric quantum error-correcting codes.
