Multi-flash (MF) photography offers a number of advantages over regular photography including removing the effects of illumination, color and texture as well as highlighting occlusion contours. Implementing MF photography on mobile devices, however, is challenging due to their restricted form factors, limited synchronization capabilities, low computational power and limited interface connectivi...

To build a platform for (high, sustainable) use, we need to know what will thrill users. Finding the right concoction of technology, functionality and design to delight users takes a thousand decisions, pivots and changes. The JSTOR Labs team has been using Flash Builds – high-intensity, short-burst, user-driven development efforts – in order to prototype new ideas and get to a user saying “Wow...

A new approach for start-up of empty cold reactive distillation columns by means of feedback control strategies is presented. In this paper, the discontinuous stage of startup is taken into account. This stage begins with the fill-up and heating process of the empty cold column and ends if vapour reaches the condenser. A corresponding model for the start-up process is developed. The control str...

this paper presents a new strategy based on multi-stage fuzzy (msf) pid controller based on artificial bee colony (abc) for damping power system stabilizer (pss) in multi-machine environment. the recent studies in artificial intelligence demonstrated that the abc optimization is strong intelligent method in complicated stability problems. also, finding the parameters of pid controller in power ...

In the chemical industry the demands regarding process efficiency are permanently increasing. At the same time methods to design indiviual process stages and interconnect them to higly integrated process are reaching their preformance limit. To overcome these limitations the focus of current research has turned to combined processes, i.e. processes that combine the tasks of different process st...

Solvent is one of the important components in chemical processes. The type solvent that often used paint and coating industry a hydrocarbon-based which consists diverse complex mixture liquids contains aliphatic, alicyclic aromatic (C5-C8) elements. Aromatic hydrocarbons are environmental pollutants known to be toxic, carcinogenic mutagenic, so with an content less than 1% needed. An appropriat...

The thermodynamic and economic suitability of four geothermal power systems is analyzed. When the heat source temperature ranges from 100-150?C, performance indicators capacity per unit geo-fluid, exergy efficiency, payback period, net present value internal rate return for types system are calculated. results show that when increases geo-fluid single flash, organic rankine cycle (ORC), double ...
