Hydrogen gas sample environment for TOSCA

Gas diffusion electrodes improve hydrogen gas mass transfer for a hydrogen oxidizing bioanode

Background Bioelectrochemical systems (BESs) are capable of recovery of metals at a cathode through oxidation of organic substrate at an anode. Recently, also hydrogen gas was used as an electron donor for recovery of copper in BESs. Oxidation of hydrogen gas produced a current density of 0.8 A m-2 and combined with Cu2+ reduction at the cathode, produced 0.25 W m-2. The main factor limiting cu...

Hydrogen Gas Cutting System

Recently, the introduction of advanced “Hydrogen Gas Cutting” was investigated but finally abandoned due to the problems of several accidents occurred, cost merit and safety. The facility is called “Hydrogen-Oxygen Mixture Gas Generation System” and stores the hydrogen detonating gas (when hydrogen and oxygen are mixed to 2:1 in volume ratio, the mixture gas violently explodes if ignited), so t...

Constraint Monitoring in TOSCA

The Job-Shop Scheduling Problem (JSSP) deals with the allocation of resources over time to factory operations. Allocations are subject to various constraints (e.g., production precedence relationships, factory capacity constraints, and limits on the allowable number of machine setups) which must be satisfied for a schedule to be valid. The identification of constraint violations and the monitor...

Vinothek - A Self-Service Portal for TOSCA

The TOSCA standard provides a means to describe Cloud applications and their management in a portable way. TOSCA-based applications can be deployed on various standard-compliant TOSCA Runtimes. Vinothek is a Web-based Self-Service Portal that hides the technical details of TOSCA Runtimes and provides end users a simple graphical interface to provision Cloud applications on demand. This demonstr...
