mean that today’s computers are vastly different from those of 30 years ago, such that many OLTP databases will now fit in main memory, and most OLTP transactions can be processed in milliseconds or less. Yet database architecture has changed little. Based on this observation, we look at some

Israel’s historical building technology is not different or outstanding in any of its technological characteristics relative to the Mediterranean Sea region and the Near East culture. But, since Israel is both the crossing point and passage for major historical events and cultures

-1880. The Torrey Pines Lodge (now referred to as the “Museum Store”) is “modern, ” built in 1922. But the material and techniques have a history dating from 8000 years ago, with many varieties of earthen construction. In the world’s drier regions today, 30 % of the population lives in such construction, largely

An important goal of chiller operation is to produce the refrigerated water as economically as possible. The coefficient of performance of chilled water systems is closely related to the temperature lift. In many applications in building services engineering, a temperature lift of 10 – 20 K

.0 Tg in 1996 to 5.3–7.3 Tg by 2030 and to 4.3–6.1 Tg by 2050, across the range of scenarios. We project that OC emissions will decline from 34 Tg in 1996 to 24–30 Tg by 2030 and to 21–28 Tg by 2050. The introduction of advanced technology with lower emission rates, as well as a shift away from the use
