the bulk of the world's phosphate reserves is located in sedimentary horizons that contain appreciable amounts of carbonate. during beneficiation of phosphate rocks, huge amounts of oversize phosphate rocks are rejected from crushers. this reject also mostly contains low tricalcium phosphate and high carbonate content. in this study, experiments have been carried out to reduce/eliminate carbona...

VERTADTM is an auto-thermophilic aerobic digestion process, employing a subsurface vertical reactor to aerobically digest mixed primary and secondary wastewater treatment solids. High metabolic activity results in heat generation, which enables the production of Class A Biosolids at short solids retention times (SRT). Currently the Technology Assessment Program of the King County Wastewater Tre...

You are probably deploying different types of small cells from multiple vendors, including residential small cells, indoor small cells for buildings, and public small cells in indoor hotspots. Most 3G small cells today are passive in operation they do some auto-configuration on start-up but can’t react to changes in traffic or in their radio environment. Others, such as Cisco Universal Small Ce...

We trace the evolution of the auto component supply chain in India (following the opening of the Indian economy in 1990) using a combination of data on firm and sectoral performance, customer satisfaction surveys and interviews with experts. During the last decade, the industry has made remarkable progress on multiple fronts. This is particularly true with regard to quality ten firms in this in...

The degree of income inequality in Sweden has varied substantially since the 1970s. This study analyzes whether this variation has affected the crime rate using a panel of Swedish county-level data for the period 1973–2000. We consider various measures of income inequality to evaluate which part of the distribution that matters most in determining crime rates. Our results indicate that there is...

We study the role of latent space dimensionality in Wasserstein auto-encoders (WAEs). Through experimentation on synthetic and real datasets, we argue that random encoders should be preferred over deterministic encoders.

OpenCL standard reaches more wider audience due to increasing the number of devices supporting it. This situation puts developers who want performance on large range of platforms in a difficult position. To solve this problem, autotuning frameworks are deployed. But the problem of design exploration space is seriously large because of OpenCL parameters. In this work, we introduce an approach wh...

In the so called "one way" electric carsharing system, users can take a car at a station, use and leave it at another station. This process usually leads to a situation where some stations are full while others are empty. The system is especially compelling because vehicles are electrical and a minimal charging time is required. Therefore, a balanced system requires the optimal distribution of ...

We provide a simple model to investigate decisions about vertical separation. The key feature of this model is that more than one input is required for the final product of the downstream monopolist. We show that as the bargaining powers of independent complementary input suppliers grow larger, the downstream monopolist tends to separate from its input units. The results are related to a visibl...
