Analysis of deleted files often provides useful information for the forensic computer examiner. Knowing where to find the deleted files, and how to interpret the metadata associated with the file’s deletion, make up the cornerstone of a successful forensic computer examination. Much like an office trash-can, the Microsoft Windows Recycle Bin is a temporary holding container for files that have ...

Synthetic juice clarification was done through spiral wound ultrafiltration (UF) membrane module. Synthetic juice was clarified at two different operating conditions, such as, with and without permeates recycle at turbulent flow regime. The performance of spiral wound ultrafiltration membrane was analyzed during clarification of synthetic juice. Synthetic juice was the mixture of deionized wate...

This paper considers the modeling and control of a tubular fixed bed reactor with recycle stream for dimethyl ether (DME) production. For simulation purposes, a pseudo homogeneous model has been developed. By reactor simulation under steady state condition, effects of parameters such as feed rate, pressure and shell temperature are investigated. Using the steady state model, an optimizer that m...

This paper presents an algorithm for the rigorous design of thermally coupled distillation sequences using process simulators. First we show that the two side streams connections that produce a thermal ‘couple’ can be substituted by a combination of a material stream and a heat flow. In this way, the sequence of thermally coupled distillation columns can be simulated without recycle streams. Th...

Chromatographic separations are widespread in the fine chemicals and pharmaceutical industries for the downstream processing of complex mixtures with similar thermodynamic properties. In recent years, continuous chromatographic processes, in particular Simulated Moving Bed (SMB) processes are increasingly applied in industry. SMB processes are characterized by a counter-current movement of the ...

In the transition from a fossil to a bio-based economy, it has become an important challenge to maximally recuperate and recycle valuable nutrients coming from manure and digestate processing. Membrane filtration is a suitable technology to separate valuable nutrients in easily transportable concentrates which could potentially be re-used as green fertilizers, in the meantime producing high qua...

on waste can alter the optimum transition path. In the optima with recycle, the lower waste penalty from reduced buildup of 239Pu more than compensates for the separations and fuel fabrication facility costs. Figure 3 shows this buildup for each of the runs. However, with a high repository discount (run 3) recycle technology is unable to compete with cheap direct disposal. The optimum in run 4 ...

this comprehensive work explores the research performed inoptimization of the collection bin and in recycle bin location-allocation issues in solidwaste management. although the collection phase of solid waste management accountsfor a significant proportion of the municipal budget, it has attracted only limitedattention of the researchers. optimization of the collection bin and recycle bin loca...
