In this paper we discuss problems and solutions pertaining to the interaction of components representing parallel applications. We introduce the notion of a collective port which is an extension of the Common Component Architecture (CCA) ports and allows collective components representing parallel applications to interact as one entity. We further describe a class of translation components, whi...

This paper examines the relationship between distributor backorder performance and its inventory levels under Vendor Managed Inventory (VMI) in a supply chain that consists of distributors and manufacturers. We construct a principal-agent model to show that distributors' inventory managed by manufacturers can be used to induce distributor efforts, which are unobservable to the manufacturers, in...

Predicting conversion rates (CVRs) in display advertising (e.g., predicting the proportion of users who purchase an item (i.e., a conversion) after its corresponding ad is clicked) is important when measuring the effects of ads shown to users and to understanding the interests of the users. There is generally a time delay (i.e., so-called delayed feedback) between the ad click and conversion. O...

An 8bit two-step time-to-digital converter (TDC) with a novel digital switched ringoscillator based time amplifier (TA) is demonstrated in 65nm CMOS. The proposed TA achieves a predictable and programmable gain without requiring any calibration. The implemented 8bit two-step TDC with a 16x TA gain achieves a time resolution of 2.6ps at 80MS/s conversion rate while consuming 2mW. The measured DN...

An increasing focus on datacenter efficiency, combined with the evolving trend of microprocessor core voltages below 1V requires an analysis of existing and proposed datacenter power delivery architectures. Additionally, multi-core architectures are increasing the number of cores per blade, thereby increasing overall power. Here, four distinct power delivery architectures will be analyzed and b...

To improve the controllability of the electric power output and the economic performance of a large-scale wind farm, an auxiliary energy storage system is required. This paper deals with the rule of planning reasonable energy storage power and capacity based on the historical annual mean wind speed data, the probability density of the pulsating wind power output, and the warranted firm power pr...

statement of problem: the degree of conversion depends on the material composition, light source properties, distance from light source, light intensity, curing time, and other factors such as shade and translucency. objectives: in the present study, we evaluated the effects of different light- curing modes and shades of methacrylate and silorane-based resin composites on the degree of conversi...

as an alternative to chromate conversion coatings, rare-earth coatings especially cerium, because of the low toxicity, have attracted considerable attention. using dip immersion method, cerium-based conversion coating was deposited on aluminum 2024. corrosion resistance was studied in 3.5 wt.% nacl solution using potentiodynamic polarization, electrochemical impedance spectroscopy, and surface ...

a detailed model of wind power station, including double fed induction generator, dfig is presented in this paper. two control mechanisms are included in the model. the inner control system uses stator flux oriented control for the rotor side converter and grid voltage vector control for the grid side converter. the outer control system is used for wind turbine pitch angle. pscad/emtdc is used ...

This paper describes the issues involved in sharing data among processes executing co-operatively in a heterogeneous computing environment. In a heterogeneous environment, the physical representation of a data object may need to be transformed when the object is moved from one type of processor to another. As a part of a larger project to build a heterogeneous distributed shared memory system w...
