Previous issue date: 2008-04-23 / The computers programming activity has its origins preceding the existence
of the machine itself. Taking as a starting point the invention of the french silkweaver
Joseph-Marie Jacquard, who built in the beginning of the 19th Century a
programmable loom, using punched-cards, this paper intends to show the relations
between the loom mechanical programming activity and the actual computers
programming.
Through the analisis of articles published in important periodicals of the 19th
Century, not yet explored in the history of information technology studies, we
comment some debates and repercussions that followed Jacquard s invention. We
also work with some modifications that occurred in that programmable machine,
mainly in the area of punched-cards.
Among others, we analyse the works of the british Charles Babbage in the
19th Century and Herman Hollerith at the end of 19th Century, seeking verification
of how Jacquard s ideas spread when applied in other activities with no relation
with the weaver s work.
Therefore this paper intends to contribute for the history of information
technology studies by the analisis of the origins of some concepts that still remain
basics to this field of science nowadays / A atividade de programação dos computadores tem origens que antecedem
a existência dessa máquina. Tomando como ponto de partida o invento do tecelão
francês Joseph-Marie Jacquard, que no início do século XIX construiu um tear
programável que usava cartões perfurados, este trabalho procura mostrar relações
da programação mecânica do tear com a programação dos computadores atuais.
A partir da análise de artigos publicados em relevantes periódicos do século
XIX, estes ainda pouco explorados nos estudos de história da informática, são
comentados alguns debates e repercussões decorrentes da divulgação do invento
de Jacquard. Destacam-se também algumas modificações introduzidas nessa
máquina programável, especialmente no que se refere aos cartões perfurados.
Foram também analisados entre outros, o trabalho do inglês Charles
Babbage em meados do século XIX, e posteriormente do norte-americano Herman
Hollerith no final desse mesmo século, procurando verificar como as idéias de
Jacquard estenderam-se à medida que passaram a ser utilizadas em outras
atividades que nada tinham a ver com o processo de tecelagem.
Portanto, este trabalho pretende contribuir para o estudo da história da
informática por meio da análise das origens de alguns conceitos que continuam a
fundamentar esse campo do conhecimento até os dias de hoje

Vícepodlažní dřevostavba / Multi-storey Wooden BuildingMacháčková, Eva January 2013 (has links)
Master’s thesis deals with complete project documentation of newly built object of library and mediatheque located on the site in České Budějovice. It is a three-storey building divided into three parts, one-storey, two-storey and three-storey. It is partly basement. The underground part is devoted to main storage spaces of library services, management offices and social facilities for staff (toilets, changing rooms, washrooms). This part of the building has own entrance for employees. In the 1st floor is located the main library area along with exhibition spaces and the main entrance for visitors with self service cloakroom. In the 2nd floor are designed library spaces for visually impaired persons with fund of audio books, CDs and DVDs, a lecture hall with a projector and own kitchen and space for reading magazines and periodicals. From this floor is possible access to the outdoor terrace, which has own terrace furniture store nearby. In the 3rd floor is located a literary café with its own facilities. In each floor are also designed sanitary facilities for use by persons with limited ability of movement and orientation. All floors are connected by stairs and passenger lifts. In terms of construction, the building is designed as a frame, in the underground parts made of reinforced concrete, the overhead of glued laminated timber elements. The ceiling structure designed over the underground floor is monolithic reinforced concrete slab. The ceilings in the upper part are designed as a wooden beamed made of the glued laminated timber elements. The building has a pent roof created by wooden trusses assembled with punched metal plate fasteners. The foundations are designed as belts and footings. The study, detailed documentation, thermal-technical evaluation of selected structures and fire safety of the building are processed. For processing of the thesis were used software AutoCAD 2010, Teplo 2011, Area 2011, Ztráty 2011 and Fire NX 802 PRO.
