Construction Techniques Of Traditional Houses In Nevsehir, Case Study On Urgup, Mustafapasa And IbrahimpasaSolmaz, Funda 01 February 2013 (has links) (PDF)
The aim of this study is to survey the construction techniques of the traditional houses in Nevsehir and to make a comprehensive study which will guide for the further conservation works. In this manner, the terms of construction techniques were understood and defined basically before they altered. To achieve this goal, firstly literature reviews were done about traditional houses in Turkey. General characteristics and history of the region as well as Cappadocia traditional houses were studied. The settlements which will be studied were chosen with the comprehensive field surveys. Meanwhile, the base drawings and maps of the settlements were gathered from municipalities and other public organizations of Nevsehir. In detailed field surveys, 20 houses were selected for surveying. After that, general architectural properties of the houses were investigated and measured drawings and sketches were drawn in detail. A code system which is special to this thesis was developed and applied to the drawings. Building parts were analyzed and defined from foundation to roof. Moreover, architectural elements were also described and classified according to their construction technique. In this survey, it is considered not only the construction technique but also the material and usage areas of building units. Frequency of the building units and their classifications can easily be seen on the drawings and tables. Thus, Nevsehir traditional houses were studied in detail and a general evaluation was done about the construction techniques and architectural features of Nevsehir.

Increasing the utilisation of hybrid concrete construction in South AfricaHanekom, Rojean 12 1900 (has links)
Thesis (MScEng)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: Hybrid concrete construction (HCC) is a construction technique that makes use of both in-situ and pre-fabricated
concrete products by making optimum use of the advantages of both these methods in the same project. Although
the advantages of this building method is well recognised throughout the world and a feasibility study illustrated
that HCC is a suitable building method in South Africa, it remains under-utilised in the country.
HCC encourages early involvement from the project team and provides clients with the best value projects and a
"win-win" situation for the project team during the project development. The objective of this study is to identify
barriers that prohibit an increased utilisation of HCC for the South African construction industry. Additionally, it
provides possible solutions to overcome these barriers. These proposed solutions are similar to the programmes
and methods that are implemented in other countries to improve their HCC utilisation. Furthermore, drivers are
identified in this study to implement these solutions in the industry and a proposed "change model" is developed
for private companies to assist with the change process.
This study is unique because current South African conditions are used to establish the barriers and solutions.
Furthermore, it takes into account that not all countries have such progressive construction industries as the
European markets and therefore it considers solutions and drivers that are suitable for less advanced industries
such as South Africa. The model that is proposed is applicable to any industry regardless of its nature or country.
Although the United Kingdom is not the widest user of pre-fabricated concrete products, their HCC research is
extensive, making it a suitable comparative country for the South African construction industry.
During the investigation, the procurement methods in South Africa were found to be traditional and do not
allow for early involvement or partnering in the project team. To obtain early involvement, it is critical to initiate
methods such as design-and-build, contract management or public-private-partnerships during the procurement
phase.
Decision and design assistance from the whole project team and software tools are essential when HCC is
considered. Because the South African construction industry does not provide such support it is advised here
to incorporate contractors from an early stage and to develop software tools that can assist during the decision
making and design process of HCC structures. The industry does not provide the project team with sufficient
training programmes that increase knowledge of HCC. Training programmes that are cognitive stimulating
must be developed for the industry. Furthermore, a database is required to illustrate the utilisation of different
pre-fabricated products and in different projects within South Africa. Labour-intensive construction regulations and green building techniques (not compulsory) are promoted in South
Africa. Labour-intensive programmes should consider the negative impact it has on the labourers and consider
HCC as a building technique because the pre-fabricated elements are manufactured in a controlled and safe
environment. It is advised that the toolkits that are used for green building accreditation, must be revised to
accommodate the additional benefits such as less waste generation, that HCC offers to a project.
Regardless of the country in which HCC is utilised, the environment must be acceptable for the innovation. By
analysing the criteria that influences the use of HCC in a country and adding weighting functions to these criteria,
the acceptability towards the innovation can be obtained.
Furthermore, public clients and companies are recognised here as drivers of change. While public clients can commit
to HCC for the cost, labour-intensive factories, green building methods, improved health and safety, training for
labourers, private companies can utilise HCC to provide best value to a project. A model is proposed here for
innovative companies that will allow them to change not only the company, but the industry towards a HCC
"mindset". / AFRIKAANSE OPSOMMING: Hibriede beton konstruksie (HBK) is ’n tegniek waarby beide voorafvervaardigde betonelemente en in-situ beton
in dieselfde projek gebruik word ten einde voordeel uit beide metodes te trek. Alhoewel die voordele van die
konstruksietegniek wel bekend is in talle lande van die wêreld en ’n uitvoerbaarheidsanalise getoon het dat HBK ’n
voordelige konstruksiemetode vir Suid-Afrika is, is dit tans onderbenut in die plaaslike sektor.
HBK bied vir kliënte projekte van goeie waarde en omdat dit vroeë betrokkenheid verg vanaf die projekspan,
resulteer dit ’n "wen-wen" situasie tydens die projekontwikkeling. Die doel van hierdie studie is om die hindernisse
te ondersoek wat veroorsaak dat HBK nie meer gereeld in Suid-Afrika gebruik word nie. Ten einde die effekte
hiervan te verminder, word moontlike oplossings vir hierdie hindernisse voorgestel. Die oplossings is gebaseer op
tegnieke en metodes wat geïmplimenteer word in ander lande waar HBK gebruik word. Rolspelers wat hierdie
verandering na HBK kan dryf word geïdentifiseer en ’n model om verandering binne ’n maatskappy te lei word
voorgestel om die rolspelers te ondersteun tydens die proses.
Hierdie studie is uniek omdat dit inligting gebruik van die huidige situasie van die Suid-Afrikaanse
konstruksie-industrie om die hindernisse en oplossings te identifiseer. Omdat nie alle konstruksie-industrieë
so vooruitstrewend is soos in Europese lande nie, is die oplossings en rolspelers relevant vir enige land wat ’n
industrie het wat soortgelyk is aan Suid-Afrika. Die model wat voorgestel word is ook relevant tot enige industrie
afgesien van die land waar nuwe tegnieke geïmplimenteer word.
Alhoewel dit bevind is dat die Verenigde Koningkryk nie die grootste gebruikers van HBK is nie, is hulle navorsing
in die veld omvattend. Daarom word die Verenigde Koningkryk beskou as ’n voorbeeld om Suid-Afrika se
konstruksie-industrie mee te vergelyk, asook om inligting van HBK te verkry.
Tydens die studie is bevind dat die projekaanstellingsmetodes van projekte in Suid-Afrika tradisioneel is, aangesien
dit nie toelaat vir vroeë betrokkenheid of vennootskappe binne die projekspan nie. Om vroeë betrokkenheid te
verkry, is dit noodsaaklik om van ontwerp-en-bou, kontrakbestuur of publiek-privaat-vernootskappe gebruik te maak.
Tans is daar geen hulp wat aan ontwerpers verleen word ten opsigte van besluitnemingsmodelle en ontwerpsagteware
wanneer HBK oorweeg word in Suid-Afrika nie. Die behoefte aan sulke bystand dui daarop dat sagtewarepakkette
ontwerp moet word wat toepaslik is vir Suid-Afrika se konstruksie-industrie. Die industrie bied nie doelgerigte en
genoegsame opleidingsprogramme aan om die industrie se kennis van HBK te verbreed nie. Addisionele opleiding
wat kognitiewe stimulasie sal bied vir die hele projekspan word aanbeveel. ’n Databasis wat HBK projekte insluit,
moet geskep word om die industrie bloot te stel aan die verskillende moonlikhede. Arbeid-intensiewe konstruksie-regulasies asook groen konstruksietegnieke (nie wetgedrewe nie) word sterk bevorder
in Suid-Afrika. Dit word hier aanbeveel, dat voorafvervaardiging se addisionele voordele in ag geneem word wanneer
hierdie regulasies en tegnieke relevant is. Hierdie voordele sluit onder meer in: die veiligheid wat aan werkers
gebied word in arbeid-intensiewe fabrieke en die vermindering van afval in HBK projekte.
Afgesien van die land waarin HBK gebruik word, moet die omgewing ontvanklik vir die tegniek wees. Deur
verskillende kriteria te analiseer wat die gebruik van HBK beïnvloed binne ’n land en geweegde faktore daaraan te
koppel, kan die ontvanklikheid van die innovasie bepaal word.
Laastens word publieke kliënte en maatskappye as die drywers (of katalisators) wat verandering kan meebring,
beskou. HKB bied onder andere die volgende voordele aan publieke kliënte: koste-effektiwiteit, arbeid-intensiewe
werk, groen konstruksie, beter gesondheid, veiligheid en opleiding vir werkers. Maatskappye kan gebruik maak van
HBK om waarde tot hul projekte toe te voeg. ’n Model word hier voorgestel om innoverende maatskappye in staat
te stel om nie net hulself nie, maar ook die industrie as ’n geheel te help om ’n gesindheidsverandering jeens HBK
te skep.

Experimental Studies On A New Class Of Combinatorial LDPC CodesDang, Rajdeep Singh 05 1900 (has links)
We implement a package for the construction of a new class of Low Density Parity Check (LDPC) codes based on a new random high girth graph construction technique, and study the performance of the codes so constructed on both the Additive White Gaussian Noise (AWGN) channel as well as the Binary Erasure Channel (BEC). Our codes are “near regular”, meaning thereby that the the left degree of any node in the Tanner graph constructed varies by at most 1 from the average left degree and so also the right degree. The simulations for rate half codes indicate that the codes perform better than both the regular Progressive Edge Growth (PEG) codes which are constructed using a similar random technique, as well as the MacKay random codes. For high rates the ARG (Almost Regular high Girth) codes perform better than the PEG codes at low to medium SNR’s but the PEG codes seem to do better at high SNR’s. We have tried to track both near codewords as well as small weight codewords for these codes to examine the performance at high rates. For the binary erasure channel the performance of the ARG codes is better than that of the PEG codes. We have also proposed a modification of the sum-product decoding algorithm, where a quantity called the “node credibility” is used to appropriately process messages to check nodes. This technique substantially reduces the error rates at signal to noise ratios of 2.5dB and beyond for the codes experimented on. The average number of iterations to achieve this improved performance is practically the same as that for the traditional sum-product algorithm.
