An Architectural Study On Miniature Parks And Miniature Models: MiniaturkOsmanoglu, Esin 01 January 2005 (has links) (PDF)
This thesis is an architectural study surveying on miniature parks and miniature models exhibited in them and particularly focuses on Miniaturk - the first miniature park of Turkey- located in Istanbul. It is established as an environment containing a group of miniature models of buildings and landscapes, which display the variety, and richness of the cultural tradition of the previous and contemporary Anatolian civilizations, and especially Ottoman grandeur. In this study, it is argued that Miniaturk stands as a hybrid category between a museum, a public park and entertainment centre. Miniaturk is also conceived as an architectural environment providing a possible ground to discuss the conceptions, misconceptions and presuppositions about architecture in the popular realm and in the professional and disciplinary framework. Thereby, Miniaturk is investigated through the processes of its production including the initial design idea and all the stages of its construction.
This study also tries to discuss the miniature models from different points of view. Whether they are considered as tools of architectural representation or not by the professionals, the popularity and the communicative advantage of these models can be used to arouse interest in the cultural and historical heritage as well as the contemporary architecture. The daily life of man on the street is strictly connected with architecture / therefore Miniaturk requires recognition as an environment for realization of these connections and relations.

Evaluation Of Pushover Analysis Procedures For Frame StructuresOguz, Sermin 01 May 2005 (has links) (PDF)
Pushover analysis involves certain approximations and simplifications that some
amount of variation is always expected to exist in seismic demand prediction of pushover
analysis. In literature, some improved pushover procedures have been proposed to
overcome the certain limitations of traditional pushover procedures.
The effects and the accuracy of invariant lateral load patterns utilised in pushover
analysis to predict the behavior imposed on the structure due to randomly selected
individual ground motions causing elastic and various levels of nonlinear response were
evaluated in this study. For this purpose, pushover analyses using various invariant lateral
load patterns and Modal Pushover Analysis were performed on reinforced concrete and
steel moment resisting frames covering a broad range of fundamental periods. Certain
response parameters predicted by each pushover procedure were compared with the ' / exact' / results obtained from nonlinear dynamic analysis. The primary observations from the
study showed that the accuracy of the pushover results depends strongly on the load path,
properties of the structure and the characteristics of the ground motion.
Pushover analyses were performed by both DRAIN-2DX and SAP2000. Similar
pushover results were obtained from the two different softwares employed in the study provided that similar approach is used in modeling the nonlinear properties of members as
well as their structural features.
The accuracy of approximate procedures utilised to estimate target displacement
was also studied on frame structures. The accuracy of the predictions was observed to
depend on the approximations involved in the theory of the procedures, structural
properties and ground motion characteristics.

The Contribution Of Intellectual Property Rights Obtained By Small And Medium-sized Enterprises To Economic And Technological Development: Policies To Be ImplementedSozer, Sebnem F. 01 May 2006 (has links) (PDF)
This thesis analyses the utilization of intellectual property rights (IPRs) by small and
medium-sized enterprises (SMEs), their contribution to economic and technological
development and policies to be implemented for the SMEs to make more use of the system
in order to reach a desired level of growth.
Small and medium-scaled enterprises constitute more than 90 % of all firms almost
all over the world and a substantial proportion of employment and turnover. This fact bares
the necessity for the SMEs to make more use of the intellectual property rights system which
is one of the components of innovation and technological growth, in order to achieve the
desired level of economic and technological development.
This paper discusses the existing and possible contribution of the IPRs obtained by
SMEs to economic and technological development and the policies to be implemented in
order to encourage intensive utilization of the system by the SMEs. The results of surveys
previously carried out both in Turkey and abroad are incorporated within the results of a
survey which was organized in the context of this thesis among 86 enterprises in 12
organized industrial zones all over Turkey. The latter survey measures the IPR utilization of
the SMEs and the reasons behind under-utilization. Among the firms studied, 60 % of them
are R& / D performers, 34 % have a distinct R& / D department while 56 % of them reported to
have developed a new product, process or design. However only one third of these
innovative firms have had an IP application and the percentage was even lower with IPR
supports / only 2.3 % of the firms applied for IPR supports. The main reason for this underutilization
of both IPRs and IPR supports was found as lack of awareness. Policy proposals
were tried to be put forward depending on the findings of the survey and raising awareness
was defined as the most important measure to be taken.

Ο στόχος της παρούσας διπλωματικής εργασίας είναι η παρουσίαση της χρησιμότητας του ηλεκτρονικού υπολογιστή στην εκπαιδευτική διαδικασία, η ευρεία χρήση των βάσεων δεδομένων στον σύγχρονο κόσμο καθώς και η μελέτη των λειτουργικών περιοχών μίας βάσης δεδομένων. Επίσης, παρουσιάζεται ο τρόπος με τον οποίο οργανώνονται τα δεδομένα μιας βάσης δεδομένων στο σκληρό δίσκο και η χρησιμότητα των ευρετηρίων.
Στο πρώτο κεφάλαιο, γίνεται μια εισαγωγή στην χρησιμότητα του ηλεκτρονικού υπολογιστή στην καθημερινότητα μας και κυρίως, στην εισβολή του στην εκπαιδευτική διαδικασία. Παρουσιάζονται κάποια κύρια στοιχεία που κάνουν τον Η/Υ απαραίτητο - πλέον - στην εκπαίδευση, οι τρόποι με τους οποίους μπορεί να χρησιμοποιηθεί στην εκπαίδευση και φυσικά η μεγάλη συμβολή της συνεργατικής μάθησης με την βοήθεια των ηλεκτρονικών υπολογιστών.
Στο δεύτερο κεφάλαιο, αναφέρεται η γενική ιδέα των Βάσεων Δεδομένων, η εξέλιξή τους και κάποια ιστορικά στοιχεία. Στη συνέχεια παρουσιάζονται τα βασικά στοιχεία της δομής των βάσεων δεδομένων και οι λειτουργικές περιοχές τους (αρχιτεκτονική, μοντέλα, γλώσσες, ασφάλεια).
Στο τρίτο κεφάλαιο, ασχολούμαστε με την αποθήκευση των βάσεων δεδομένων, κυρίως σε δευτερεύοντα αποθηκευτικά μέσα, όπως ο σκληρός δίσκος. Αναφέρονται τα επιμέρους στοιχεία ενός σκληρού δίσκου και τον τρόπο με τον οποίο αποθηκεύονται τα δεδομένα σε μορφή εγγραφών, τοντρόπο οργάνωσης και διάταξης των εγγραφών σε αρχεία καθώς και περιληπτικά η μέθοδος του κατακερματισμού.
Στο τέταρτο κεφάλαιο, παρουσιάζεται η δομή των ευρετηρίων για την διάταξη των εγγραφών σε ένα αρχείο. Αναφέρονται οι βασικοί τύποι ευρετηρίων (πρωτέυον, δευτερεύον, συστάδων και πολυεπίπεδο) καθώς και τα δυναμικά πολυεπίπεδα ευρετήρια με την χρήση Β-δένδρων και Β+-δένδρων.
Στο πέμπτο κεφάλαιο, παρουσιάζεται μία εφαρμογή των ευρετηρίων σε μία δειγματική βάση δεδομένων (Sakila), η οποία χρησιμοποιείται για εκπαιδευτικούς σκοπούς. Συντάσσονται ερωτήματα SQL με την βοήθεια εντολών δημιουργίας ευρετηρίων, ώστε να δειχθεί και πειραματικά ότι τα ευρετήρια είναι μία πολύ καλή μέθοδος μείωσης του χρόνου αναζήτησης, ειδικά σε μία βάση με πάνω από 1000-2000 εγγραφές. / The aim of the present thesis is to show the utility of computers in education, the widespread use of databases in the modern world and the study of the functional areas of a database. It is also presented the way the data are organized in a database on the hard disk and the structure of indexes.
The first chapter includes an introduction to the usefulness of the personal computer to our everyday life and especially, in its invasion in the educational process. There are presented some key elements that make the PC necessary in education, the ways in which it can be used in education and of course the great contribution of collaborative learning with the help of computers.
The second chapter refers to the concept of databases, their development and some historical data. Also, there are presented the basic elements of the structure of databases and their functional areas (architecture, models, languages, security).
The third chapter deals with the storage of databases, particularly in a secondary storage media, such as the hard disk. There are indicated the components of a hard disk and how the data is stored in records, the organization and provision of records in files and briefly the method of hashing.
The fourth chapter presents the structure of indexes for the order of the records in a file. The basic types of indexes are described (primary, secondary, clustering and multilevel), as well as, the dynamic multi-level indexes using B-trees and B+-trees.
The fifth chapter presents an application of indexes in a sample database (Sakila), which is used for educational purposes. SQL queries are drafted with the help of create indexes command, in order to show – experimentally - that the indexes are a great way to reduce search time, especially, in a database which contains over 1000-2000 records.

Foram utilizados 36.000 peixes, da variedade Chitralada, sexualmente revertidos, onde avaliou-se diferentes densidades de estocagem (100, 200, 300 e 400 peixes m-3) e níveis protéicos da ração (28 e 32% PB), na fase de terminação (Fase 2), distribuídos em 24 tanques-rede, no reservatório da UHE de Chavantes, Rio Paranapanema SP/PR. Foram avaliadas duas produções de inverno, com médias de peso iniciais de 288,19 ± 64,21 g até atingirem peso comercial de 662,59 ± 102,73 g, nos meses de abril a julho de 2005 (103 dias) e de 2006 (95 dias). Os experimentos foram conduzidos em blocos inteiramente casualizados (fatorial) e seis repetições. Foram estimados os valores dos índices zootécnicos, ganho em peso diário (GPD), ganho em biomassa (GB), conversão alimentar aparente (CAA) e sobrevivência (S). Ocorreu efeito quadrático com diminuição dos valores do GPD e o crescente aumento do número de peixes adensados (p=0,0022). Os valores de GPD utilizando-se a ração com 32% PB foram significativamente superiores aos de 28% PB (p=0,0329). Houve interação entre os fatores densidade de estocagem e porcentagem de proteína na ração (p=0,0318) no índice de sobrevivência. Para os valores de CAA e GB não ocorreram interações entre as porcentagens de PB e densidade de estocagem (DE) (p=0,1157; 0,4058). Ocorreu efeito quadrático com os aumentos nos valores da CAA X DE (p=0,0210) e GB X DE (p=0,0002). Conclui-se que, os maiores valores de GPD mostraram que a ração de 32%PB e a densidade de 100 peixes m-3 são as mais indicadas foram as mais indicadas para essa fase de criação. / The Nile Tilapia, O. niloticus, breeding in net cages has been growing faster, uses high stocking densities, depending on artificial diet and water renewal. There were allocated 36.000 fish of the Chitralada variety, sexually reverted, where stocking densities (100, 200, 300, and 400 m³) and food protein level (28 and 32% CP) were evaluated in (phase 2), distributed in 24 net cages, in the Chavantes HPS Reservoir, Paranapanema River, SP/PR. Two winter crops were evaluated, using fish with 288,19 ± 64,21g initial mean weight up to reaching market weight of 662,59 ± 102,73g, in months of April to July 2005 (103 days) and 2006 (95 days). The experiments were carried out in entirely randomized blocks (factorial) and six replicates. The following zootechnical indexes values were studied, daily weight gain (DWG), biomass gain (BG), food conversion rate (FCR) and survival (S). Was a quadratic effect with the decrease of the DWG values and the increasing augment on the added up fish number (p=0,0022). The DWG values, using 32% CP food were significantly superior to the DWG with 28% CP food (p=0,0329). There was interaction between the stocking density and food protein percentage (p= 00,318) in the survival index. For the values of parameter FCR and BG, there were no interactions between the protein percentage in the food and stocking density (SD) (p=0,1157; 0,4058). There was a quadratic effect with the increases in the FCR X SD values (p=0,0210) and BG X SD (p=0,0002). Concluded that, the higher DWG showed that the 32% CP foodstuff and the 100 fish m-3 was the most appropriate for this phase of rearing.
