Purpose The recent research trend of building information modelling (BIM) involves interoperability and issues pertaining to the design, construction, operations, and maintenance phases of a building. However, few researchers are concerned with problems encountered in the last two phases of the building life cycle. Since BIM has been widely used in the design and construction phases, further ex...

A Data Warehouse (DW) is a database that collects and stores data from multiple remote and heterogeneous information sources. When a query is posed, it is evaluated locally, without accessing the original information sources. In this paper we deal with the issue of designing a DW, in the context of the relational model, by selecting a set of views to materialize in the DW. First, we brie y pres...

A set of technical, administrative and management activities are done in the life cycle of equipment, to be located in good condition and have proper and expected functioning. This is refers to be, maintenance management system (MMS). The framework and models of assessment in order to enhance effectiveness of a MMS could be proposed in two categories: qualitative and quantitative. In this resea...

introduction: in health care services, preventing problems and failures is more efficient than concentrating on correcting them. repairs are always expensive, as they require highly specialized personnel and costly spare parts. regular inspecting and servicing, using manual services and checklists, would maximize the impact of maintenance and minimize the costs. it is thus important to introduc...

maintenance treatment for patients with acute myeloid leukemia (aml) in remission has recently been controversially discussed and even abandoned by several groups. an analysis of 16 published multicenter trials, however, revealed the highest probabilities of relapse free survival (rfs) in the range of 35-42 % at 4-5 years only in patients assigned to maintenance treatment when adult age and int...

The Air Force Satellite Control Network (AFSCN) is composed of eight worldwide fixed remote tracking stations (Space Ground Link Stations, SGLS) hosting 15 antennas, plus two mission control nodes, one at Onizuka AFB, CA and the other at Schriever AFB, CO. One of the AFSCN message formats provides AFSCN metric data (range, range-rate, azimuth, and elevation). Currently the AFSCN metric data are...

From the basic impact of nutrient intake on health maintenance to the psychosocial benefits of mealtime, great advancements in nutritional sciences for support of human space travel have occurred over the past 50 years. Nutrition in space has many areas of impact, including provision of required nutrients and maintenance of endocrine, immune, and musculoskeletal systems. It is affected by envir...

With the further popularization of 3D design in substation engineering, previous works provide lots data foundations for digital operation and maintenance. Different from editing requirements model stage, higher are put forward corresponding speed bearing capacity graphics platform maintenance stage. At present, application methods library mainly based on geographic information (GIS) vector pla...
