Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Design of the 2nd Floor of a Warehouse
No full textLõputöö eesmärgiks oli projekteerida 1980. aastal kasutusele võetud laohoone keskosale
teine korrus juurde. Hetkeolukorras piirneb projekteeritav osa ühelt poolt juba 11,6 m
kõrguse hoone osaga, mida nii pikendatakse 20,7 m võrra. Projekteeritava osa esimesel
korrusel paiknevad 3,46x2,3 m aknaavad ning 3,72x3,19 m suurused ukseavad. Laol on
olemasolevad müürid silikaattellistest, ruum on kaetud 150 mm paksuste
õõnespaneelidega. Hoone on mõõdetud autori poolt, sest originaal projekti teadaolevalt ei
eksisteeri.
Töös on arvutatud lume-, tuule- ja omakaalukoormuseid kandepiirseisundis. Katuse
profiilplekiks on valitud Ruuki toode T45-60L-905. Katuseferm on dimensioneeritud uuena.
Teise korruse seinte müürikivideks on valitud 240-Columbia õõnesplokk, mis on
täisbetoneeritud. Müürile on ettenähtud 200 mm paksune raudbetoonvöö, mis hajutab
katusesõrestikelt tulevaid koormuseid. Kontrollitud on arvutuslikult pingeid vöö all ning
seina kandevõimet keskmises lõikes (m).
Esimese korruse aknavahepostile laskuvaid koormuseid on kontrollitud lõikes (i) ehk kõige
kõrgemas 3,72 m kõrguses punktis ning lõikes (m). Kontroll aknavahepostile on töös
olulisem kui uksevahepostile kuna aknapost on oma mõõtmetelt väiksem. Uksevaheposti
kontroll teostati turvalisuse kaalutlustel samuti.
Postide kontrollarvutuste tulemustest on järeldatud, et aknavahepost vajab teise korruse
koormuse vastu võtmiseks lisatugevdust, mistõttu on sellele välja arvutatud metallsärk.Design of the 2nd Floor of a Warehouse
The aim of the graduation thesis was to design a second floor in the central part of the
warehouse that was put into use in 1980. In the current situation, the part to be designed
borders on one side by the part of the building that is already 11.6 m high, which will thus
be extended by 20.7 m. On the first floor of the part being designed, there are 3.46x2.3 m
window openings and 3.72x3.19 m door openings. The existing walls of the warehouse are
made of silicate bricks, and the space is covered with 150 mm thick hollow panels. The
building has been measured by the author, as the original design is not known to exist.
The snow, wind, and self-weight loads in the bearing limit state have been calculated in the
work. Ruuki's product T45-60L-905 has been chosen as the profile sheet for the roof. The
roof truss is dimensioned as new. 240-Columbia hollow blocks, which are fully concreted,
have been chosen as the masonry stones for the walls of the second floor. A 200 mm thick
reinforced concrete belt is provided for the wall, which disperses the loads coming from the
roof trusses. The stresses under the belt and the bearing capacity of the wall in the middle
section (m) have been checked.
Loads falling on the first-floor window lintel have been checked in section (i), i.e., the
highest point at a height of 3.72 m, and in section (m). Checking the window jamb is more
important than the door jamb because the window jamb is smaller in size. The door jamb
was checked for security reasons as well.
From the results of the post-control calculations, it has been concluded that the window
lintel needs additional reinforcement to receive the load of the second floor, which is why
a metal jacket was calculated for it

Design of Glass Facades, Windows and Doors on the Example of the Courthouse
No full textLõputöös on kogutud vajalik informatsioon avatäidete ja klaasfassaadide projekteerimiseks: sissemurdmiskindlus, isikuturvalisus, helinõue, päikesefaktor ning eraldi akende, uste ja fassaadide kirjeldus. Sarnase projekti lahendamisel võib lõputööd kasutada abistava materjalina. Selleks, et lõputöö maht jääks kehtestatud piiridesse pole käesolevas töös kajastatud profiilide töötluseid, värvimistehnoloogiat, saagimise optimeeringuid ja koostamislehti. Samal põhjusel ei ole eraldi toodud kinnituste ega klaasfassaadide kronsteinide tugevusarvutusi. Lõputöö koostamisel on läbi vaadatud palju standardeid. Rootsi ja Eesti metoodikatega saadud arvutustulemused on võrreldud omavahel. Rootsis, Norrköpingis kasutatakse tuule baaskiirust 24 m/s, kuid Eestis 21 m/s, see erinevus mõjutab oluliselt arvutusliku tippkiirusrõhu väärtust. Rootsis saadakse sarnastel tingimustel 0,6870 kN/m2 ja Eestis 0,5787 kN/m2. Tuulerõhu arvutuses Rootsi standardi rahvuslik lisa lubab kasutada metoodikat mis sõltuvalt konstruktsiooni kõrgusest võimaldab kasutada erinevaid koormuseid. Näidiseks võetud esimese korruse akna A tsooni tuulerõhk on: Rootsis w_neto=0,66 kN/m^2 kuid Eestis oleks 0,82 kN/m^2. Suur vahe tekib sellest, et Rootsi tuulerõhk on valitud esimesel korrusel asuva avatäite ülemise serva järgi ning Eesti tuulerõhk on võetud arvestades kogu hoone kõrgust. Järgmise arvutusplokina oli uuritud temperatuurikoormuse mõju laiadele akendele. Siinkohal Rootsi ja Eesti arvutusmetoodikad olid sarnased ainukese erinevusega, et Rootsis on madalam minimaalne temperatuur ja kõrgem maksimaalne temperatuur aasta jooksul. Suuremad temperatuurivahed põhjustavad suurema profiili lühenemise/pikenemise. Eestis on saadud geomeetriast tingitud maksimaalne lubatud profiili pikkus 5608,9 mm ning Rootsis 5401,2 mm. Silikoonvuugi tolerants mängib antud projektis väikest rolli kuna see asub sisetingimustes. Lõputöö koostamise ajal Kohtumaja avatäidete projekteerimine pole veel lõppenud, kuid enamus sõlmi on läbi töötatud ja mõned neist on näidatud lõputöös. Samuti tehti projektis muudatusi, näiteks mõned klaaspaketid on asendatud sarnastega et fassaadides kasutatud klaasing oleks võimalikult ühesuguse paksusega. Lõputöö võib olla kasulik ehitusega seotud inimestele silmaringi laiendamiseks. Neid andmeid võib nimetada baasiks, mida teab iga välisavatäidete projekteerija.In this thesis the author has collected and explained the necessary information for designing windows, doors and glass facades and that has been used in designing the windows and doors of the Courthouse. The edifice being built is located in Norrköping in Sweden. This enables to compare the differences in Estonian and Swedish regulations both in terms of classification and calculation methods. As source data, architectural and constructive designs prepared by various undertakings have been used. Windows, doors and glass facades are an important part of construction. They must comply with many different requirements, including burglary resistance, personal safety, sound insulation requirement, U-value and glass solar factor. All the abovementioned parametres influence the choice of glazing and profile systems. The author of the thesis has conducted an analysis of European standards including their national supplements, requirements of the manufacturers of glass and aluminium systems and other regulations. Accordingly, special focus has been paid to the remarks that are important for designing the windows, doors and glass facades. In addition, the design includes geometrical solutions of some special requirements. Since there are load-bearing pillars within the window openings, it requires a solution that is glazed from the outside. The shape of the glass facades is an arc consisting of sectors. In the thesis the author describes the activities of the designer at different stages of designwork in the order of their completion: preparation of approval drawings, ordering of materials, preparation of element drawings and montage drawings. During the preparation of the thesis, approval drawings have been made, the material has been ordered by elements, but the element drawings and montage drawings have been made only in part. Calculations form a significant part of the thesis. In order to ensure that calculation results are representative for the whole building, the calculations have been carried out on the structures to which the highest loads of this type apply and the results have been compared with the maximum permissible values. For the beam under the heaviest glass, a deflection has been calculated, resulting from the weight of the glass and the beam. The wind load is calculated for the profiles of the window and the glass facade, which are located between larger glass fields. There is a significant difference between the Estonian and Swedish wind load calculation methods – although Sweden uses the same or higher base wind speed values than Estonia, it is allowed to calculate the top speed pressure by using the actual height of the partition opening and not the entire height of the building, provided that certain conditions are met. The impact of wind zones is presented by floor. In the preparation of this design, special attention has been paid to the width of the windows. Due to the effect of the temperature load, many windows consist of several parts. Also a small difference in the measures of shortening/lengthening in Estonia and Sweden has been discovered by the author. All maximum values of calculated loads are compared with the values of the profiles used. In order to keep the volume of the thesis within the permitted limits, strength calculations for individual fixtures and brackets of glass facades have not been provided. The thesis highlights the knowledge that is used by the designers of glazed partitions. The author of this thesis prepared Excel spreadsheets when performing calculations, which can be used also in the future for finding loads. The theoretical part can also be used as an auxiliary material for the preparation of similar projects. This thesis can be useful for construction specialists in broadening their horizons
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Intern experience at CH���M Hill, Inc.: an internship report
No full textIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
Transition to turbulence in a qblique shock-wave/boundary-layer interaction at M=15
No full textDirect numerical simulations are carried out for different forcing techniques to trigger transition during the interaction between an oblique shock-wave and a laminar boundary-layer at M = 1.5. Three forcing methods are used: a) forcing of oblique unstable modes, whose shape and behaviour are determined by the local linear stability theory, b) broadband free-stream acoustic disturbances, and c) a cold plasma flow control device. While the oblique-mode breakdown is dominant for low-amplitude forcing, long streaky structures drive the transition process in a high-amplitude disturbance environment. LES are also performed on the experimental setup by the Institute of Theoretical and Applied Mechanics (ITAM) from Novosibirsk State University with cold plasma actuation. As well as the disturbance type, the effect of Reynolds number and forcing amplitude will be investigated
