safe operation. The deuterium (D) removal efficiency in tungsten (W) by energetic hydrogen (H) ions under room temperature and baking under 623 K were studied by thermal desorption spectroscopy (TDS). Iron (Fe) damaged W with various damage level by 6 MeV Fe. was adopted to simulate neutron irradiat

Michiel Hazewinkel,Jan C. Willems and nitrates NO.. The water thus treated is called plasma activated water and have applications in medicine and agriculture. In the present work, surface DBD micro plasma working in air at atmospheric pressure is used to treat a small amount of deionized water. The surface DBD plasma was generated

M. H. A. Davis,Steven I. Marcusatabases, i. e., databases that incorporate both transaction and valid time dimensions. In this paper we first discuss the issues involved in addressing general bitemporal queries and then propose two general approaches in solving such queries. For simplicity we present our findings in relation to t

Michiel Hazewinkeled database design tools such as the relational model are unsatisfactory for the development of database systems in which attribute values change over time. Such writers urge that valid time — the interval over which a data item is valid — be treated differently from time which is an ordinary attrib

Michiel Hazewinkel review the schemes of ℒ-constraint databases and indefinite ℒ -constraint databases where ℒ, the parameter, is a first-order constraint language. Then we consider several instances of these schemes where ℒ is a language for expressing information about atomic data values and time. We collectively r

measured using strain gauges. Usually, the force transducers, being unidirectional, are able to sense only axial force or torque. This paper presents an innovative force transducer for sensing triaxial loads and moments pertaining to its unique shape which allows strategic placement of strain gauges
