control systems provide mechanisms for branching into multiple lines of development and merging source code from one development line into another. However, the techniques, policies and guidelines for using these mechanisms are often misapplied or not fully understood. This is unfortunate, since the use or misuse of branching and merging can make or break a parallel software development project. Streamed Lines is a pattern language for organizing related lines of development into appropriately diverging and converging streams of source code changes

Livestock Production Science 77 (2002) 349--353

The goal was to assess the impact that human interventions in natural ventilation may have on microclimatic factors in a barn and on thermal comfort of dairy cows housed there. Thermal comfort of the cows in the barn was assessed from the changes in their body surface temperature. Microclimatic factors in the barn were modified by opening and closing sidewall plastic curtains in the barn and doors in alleys. While no changes in the body surface temperature were recorded when the air temperature dropped by 3.1 8C, a significant response (P , 0.01) was recorded when the air temperature dropped by 6.5 8C. Significant changes in the air velocity at temperatures within the thermoneutral range influenced thermal conditions in the barn, and significant changes in body surface temperatures caused by vascular responses (P , 0.01, P , 0.05) were recorded. It is impossible to assess thermal comfort of dairy cattle housed in barns objectively only on the basis of visually detectable thermoregulatory behaviour of the cows or of microclimatic parameters measured in barns, because different combinations of air temperatures and air velocities will result different intensity of body surface cooling. This is reflected in the variations of the body surface temperatures, which can be reliably monitored by thermography

Light versus Energy Performance of Office Rooms with Curtain Walls: A Parametric Study

AbstractA parametric study aimed at identifying the best performing solution in terms of lighting, heating and cooling demand minimization for an office room is presented. Different orientations, room and façade lay-outs, glazing and lighting control systems have been combined and 192 configurations have been analysed through a two-step process: daylight factor and dynamic daylighting metrics and the corresponding energy demand for lighting were calculated in step 1 using Daysim; the energy demand for heating and cooling was determined in step 2 using a quasi-steady state approach, to verify whether the best configurations obtained in step 1 also resulted in the lowest global energy demand
