The article describes the design and strength calculation of a low-pressure steel tank, which is used for storage hydrogen in metal alloy based on Ti Zr. An external liquid heat exchanger considered hydride tank. Strength calculations were performed to verify selected wall thickness vessel bottom type according STN EN 13322-2 standard implementation tank operating conditions.

Supervisory Control and Data Acquisition (SCADA) systems, which are widely used in monitoring and controlling critical infrastructure sectors, are highly vulnerable to cyber attacks. Current security solutions can protect SCADA systems from known cyber assaults, but most solutions require human intervention. This paper applies autonomic computing technology to monitor SCADA system performance, ...

Two new concepts have been identified for direct steam generating solar fields that charge a two-tank molten salt storage system. The use of both supercritical and superheated subcritical steam is proposed, and discussed in practical terms and with regards to thermodynamic issues of heat transfer to the salt. Both concepts are found to allow significantly higher hot-tank temperatures than solar...

Metal–organic frameworks (MOFs) are promising materials for storing natural gas in vehicular applications. Evaluation of these materials has focused on adsorption of pure methane, although commercial natural gas also contains small amounts of higher hydrocarbons such as ethane and propane, which adsorb more strongly than methane. There is, thus, a possibility that these higher hydrocarbons will...

Grey water recycling has been generally accepted and is about to move into practice in terms of sustainable development. Previous research has revealed the bacteria re-growth in grey water and reclaimed municipal water during storage. However, in most present grey water recycling practices, impacts of water quality changes during storage on the system's performance and design regulation have no...

on the Columbia River plateau, a semiarid region in south-central Washington (Fig. 1), the Hanford Site At the Hanford Site, highly radioactive and chemically aggressive served as a plutonium production facility for nuclear waste fluids have leaked from underground storage tanks into the vadose zone. This paper addresses hydrogeological issues at the weapons from 1944 to the end of the Cold War...

Abstract Designing a new construction of large-volume multi-chamber tanks or converting existing single-chamber into for storage various types petroleum products is very demanding and responsible job, from the aspect strain-stress analysis need to ensure structural integrity. From wide range conducted theoretical experimental-numerical research, this paper singles out applied method similarity ...

In this paper thermo-hydrodynamic characteristics were investigated experimentally for a new type shell-helical coiled tube heat exchanger used as storage tank of closed loop solar water heater system. Triple concentric helical coils made copper tubes (12.5mm OD and 10mm ID) with diameter (207, 152.2, 97mm) outer, middle inner respectively. The experiments carried out during clear sky days (Mar...

I-Abstract Low-Density Parity-Check (LDPC) codes, as linear block error-correcting codes (ECC), which were invented by Gallager in 1963 and rediscovered by MacKay in 1999, nowadays become a hot topic in a variety of application fields. Due to inherently paralleled decoding algorithm and near Shannon limit error-correcting performance, LDPC codes have been widely adopted in modern communication ...
