This paper presents work related to the design of distributed systems, which is useful for emerging Internet applications. We propose algorithms for searching and managing distributed information about resources and services using locally available warehouses. The concept of warehouses has been introduced in the Web Operating System (WOS) (Kropf 1999). Warehouses have the ability to decide whic...

Energy optimization in cold food storage processes is a complex issue, as many variables have to be taken into consideration, according the nature of stored. In addition, energy requires exhaustive supervision, especially cooling temperatures different types food, refrigeration essential for maintaining optimum storage, minimizing product losses. The goal this study present use digitization pro...

Multidimensional data warehouses and OLAP systems do not provide adequate means for dealing with changes in dimension data, changes appearing frequently in dynamic application areas as current business systems. As data warehouses and OLAP tools serve as decision support systems they have to reflect such changes. Temporal data warehouses propose sophisticated modelling tools for covering any cha...

Focusing on coca, coffee, gold, soy, sugar, and tea, articles in a special issue of the Austrian Journal Historical Studies 30/3 (2019) Global Commodities aim at tracing emergence commodity chains through expansion contraction frontiers. Frontier shifts imply complex – potentially conflicting interactions shaped by as well shaping socio-natural systems. Thus, contributions reveal their frontier...
