Therefore manufacturer's data sheet specifies the maximum forward current, that diode can withstand. This average current IF is the rate a diode can handle up to the forward direction when used as a rectifier. Another entry of interest in the data sheet is the forward voltade drop UF(max) when the maximum forward current occurs. An usual diode has this value 0.7-2.0V. Diode conducts easily when forward biased. Reverse biasing. The reverse current is a leakage current at the source rated voltage. Typically, silicon diodes have 1-10 microA and germanium 200-700 microA of leakage current. This value includes thermally produced current and surface leakage current. Only these currents take place, when a diode is reverse biased. At breakdown, the diode goes into avalanche where a number of carriers appear suddenly in the depletion layer. With a rectifier diode, breakdown is usually destructive. 4)Typical values: Uknee- approximatly 0.7V; UF 0.7-2.0V; leakage (IR) 1-10 microA/200-

. Ülesande vastu võtnud: Tanel Friedenthal ………………………. Abstract How are 3D and BIM Changing the Design, Fabrication and Construction of Complex Steel Structures? The adoption of three-dimensional (3D) design and construction tools have created a remarkable shift in the building industry. Intelligent 3D technology in the form of Building Information Modeling (BIM) not only promises to improve the notoriously inefficient construction process, but also opens the door for designing new geometric shapes, which until recently have been considered unbuildable. Steel has been extensively used to build some of the most challenging architectural icons of the 21st century, due to its low weight and high strength in both compression and tension. Therefore, the steel

authenticity and hence makes for long-lasting interest: for this is how things really happened. In the same vein, I have not made up any conversations, and my speculations about things not a matter of record have been marked as such in the notes in the full-length version. I have documented all important facts, except that in a few cases I have had to respect the wishes of my sources for anonymity. The original publisher submitted the manuscript to the Department of Defense on March 4, 1966, which requested three minor deletions—to all of which I acceded—before releasing the manuscript for publication.

"We've known for years that people buy based on emotions and justify their buying decision based on logic. Dr. Cialdini was able, in a lucid and cogent manner, to tell us why this happens." --MARK BLACKBURN, Sr. Vice President, Director of Insurance Operations, State Auto Insurance Companies "Dr. Cialdini's ability to relate his material directly to the specifics of what we do with our customers and how we do it, enabled us to make significant changes. His work has enabled us to gain significant competitive differentiation and advantage" -LAURENCE HOF, Vice President, Relationship Consulting, Advanta Corporation "This will help executives make better decisions and use their influence wisely ... Robert Cialdini has had a greater impact on my thinking on this topic than any other scientist." -CHARLES T. MUNGER, Vice Chairman, Berkshire Hathaway, Inc.
to re-establish the Estonian Republic in August 1991. A month later Estonia joined the United Nations. In 1997 the population reached 1.462 million; from this Estonians total 65% (950,124) and other nationalities 35%. The capital Tallinn, mentioned for the first time in 1154, has a population of 434,800 (1995). Other important towns are Tartu, Kohtla-Järve, Narva and Pärnu. Estonia is a developed industrial and agricultural country. In industrial output: oil shale, electrical energy, mineral fertilisers, paper, chemicals, building material, and textile production are prominent. In agriculture: milk, milk products, meat, grain, potatoes, fruits and vegetables. Estonian cultural life is manifold and intense, initiated by the National Awakening movement during the second half of the 19th century. Estonian folk arts date back to the remote past. In Estonia there are 27 higher educational establishments,

T h e y made me aware o f what assumptions were being carried by Hollywood-style films, and of what was not being expressed. xix THE WRITER'S JOURNEY ~ THIRD EDITION Christopher Vogler In my travels I learned that Australia, Canada, and many countries in Europe subsidize their local filmmakers, in part to help preserve and celebrate local dif ferences. Each region, department, or state operates as a small-scale movie studio, developing scripts, putting artists to work, and producing feature films and television shows. For America, I like to imagine a version of a decentralized Hollywood in which every state in the U n i o n functions like a movie studio, evaluating the stories of its citizens and advancing money to produce regional films that represent and enhance the culture of the locality while supporting the local artists.
