Hi guyz, i am starting my masters in structure and foundation engineering from HERIOT WATT university in UK..through their distant learning program.
Please shed some light on this topic. I want to have your opinion.
I did my bachelors from NUST (Times higher education ranking: 351-400)
Heriot watt ranking (351-400) & 42nd in UK
Another option was university of surrey having same worldwide ranking but 26th ranking in UK.
but its 67% more expensive than heriot watt.
In USA i liked UNIVERSITY OF SOUTHERN CALIFORNIA having top 11th position in the world but its really very expensive. It is about 300% more expensive than heriot watt..
so i have selected now the university of heriot watt based on the budget, ranking and subject.
Input your data in INPUT sheet and get outputs in SAP2000 sheet.
I'm waiting for your opinion.

ProKon (short for Professional Converter) is a 32-bit & 64 bit Microsoft Windows program that is intended to perform numerical conversions between the various units used in the scientific and business community. Early versions of ProKon were capable of performing this, and only this, function. As the program has evolved, many things have been added so that the current version is capable of doing much, much more. Following is a complete description ProKon and what ProKon is capable of doing for you. ProKon is intended for use with Windows 95, Windows 98, Windows ME, Windows NT, Windows 2000, and Windows XP. ProKon cannot be used with Windows 3.11 or earlier versions. There is a 16-bit version of ProKon available (called SICon) that is capable of this.
The primary use for ProKon is to convert numerical data to/from various units of measurement. While focusing on conversions between the metric and Imperial (English) systems of measurement, it is capable of performing conversions between many other units, foreign, ancient, and archaic. ProKon's capabilities have grown to the point that it is capable of performing well over 400,000 different unique conversions. You would have a difficult time finding a measurement unit that is not already included in ProKon. Even if you could, ProKon has the capability of storing any special conversion units that you might come up with in a special "Custom" conversion class.
The conversions in ProKon are grouped into various "Classes". Each class contains units that would logically fit in the Class description. Examples of classes are Mass, Length, Viscosity, Density, Concentration, Light, Temperature, Area, etc. In all, there are 26 Classes to select from. Each of the units contained in any Class can be converted to any of the other compatible units in the Class. Selection of a pair of units for conversion presents a calculation window in which calculations can be performed. Calculations are performed 'dynamically', meaning that as values are entered under one unit, the converted value is updated instantaneously to the other unit. Either conversion value may be edited to dynamically display results - useful for 'what if' calculations. All data shown can be printed, or copied to Windows clipboard and file.
ProKon also contains a Periodic Table of the Elements. Selecting the Periodic Table class shows the complete periodic table of the elements. Any element may be selected to bring up a window showing pertinent data on that element. Such things as atomic number, atomic weight, density, oxidation states, melting point, boiling point are shown along with descriptive text on the element giving reactivity, uses, sources, prevalence, toxicity, etc. All data shown can be printed, or copied to Windows clipboard and file.
A Class titled 'Material Density' gives density of over 600 common materials. Approximate density is given in both metric and Imperial (English) units. Densities are available for materials from acetylene to flint to mahogany to zirconium. Again, all data shown can be printed, or copied to Windows clipboard and file.
A 'Geometry' Class gives a folder of common geometric formulae. Each page of the folder shows a keyed graphic of a geometric figure along with various formulae that can be used to perform calculations pertinent to that figure. Very useful for finding that formula that you learned in school but 'forgot'.
A 'Constants' Class contains a folder of various types of numerical constants used in the scientific and academic communities. These lists are a valuable reference tool for constants used in chemistry, physics, mathematics, etc.
Also available from within ProKon is ProKalc, a pop-up combination scientific/financial calculator with a scrolling tape. The ProKon calculator is capable of performing all of the standard math operations +, -, X, /, as well as such things as logarithms, natural logs, trigonometric functions, hyperbolic functions, powers, roots, factorials, combinations, permutations, reciprocals, percentages, etc. Financial calculations such as present value, future value, loan calculations, profit/loss, interest, currency conversions, dividend, and investments can be performed. A 10-location, non-volatile memory that is saved between sessions in included. Although very intuitive and easy to use, integrated help is available for all calculator functions. All or a portion of the calculator tape can be printed or sent to clipboard or file. The ProKon calculator features 15-digit accuracy with no rounding errors.
The 'Miscellaneous' Classes actually offers 62 additional modules, some of which give access to databases of information on various topics. Others allow calculation of various types of data that are not true 'conversions' but that are, nevertheless, quite useful. Modules available are: a module for inorganic chemicals that gives data such as formula weight, density, physical form, melting point, boiling point, etc. on a very large number of inorganic chemicals, a nutritional database that gives nutritional data on a large number of food items, for instance, calories, fat content, carbohydrate content, etc. A 'Standard Sieve' module gives information such as sieve opening size, standard sieve number, wire size, etc. on the standard sieve series and a 'Wire/Sheet Gauge' module gives wire diameter and sheet thickness in both metric and Imperial units. A 'Number Base Conversion' module allows conversion of decimal, binary, octal, or hexadecimal values between the various systems and an 'Electrical Calculation' module allows calculation of various electrical properties such as ohms, volts, watts, energy cost, and electric motor properties. A 'Meteorological' module allows calculation of numerous 'weather' related values such as relative humidity, dew point, wind chill index, etc. Recent additions to Miscellaneous for contractor or engineering type work include a Concrete module that allows calculation of various information needed by contractors and those involved in calculating quantities of concrete required for concrete pours, a Lumber module allowing calculation of data related to board feet requirements, a Paint module which calculates paint requirements and theoretical paint coverage, a Twist Drill Size module giving a database of info, and a Gauge module giving thickness and diameter requirements of various systems of wire and sheet gauge. A graphical and interactive Resistor/Capacitor module allows calculation of resistance or capacitance values through a point-and-click interface. Other modules include an Irrigation module which allows calculation of irrigation requirements such as time to irrigate, amount of irrigation water required, area or quantity of water required, a Roman Numerals module which allows calculation of Roman numerals from decimal value and which allows simple math performed on Roman numerals, a Fractions module allowing conversion to and from fractions and decimals, and a Formula Weight calculator module which allows calculation of chemical formula weight by simply entering a chemical formula. To go on, there's a Sound module, an architectural symbol database, and a module that allows currency conversions to and from approximately 220 currencies from around the world. The currency rate conversion module allows for instant updates of the currency conversion factors database from the internet. These rate factors are current within a day and come to you compliments of ShowMe Software. To round out the Miscellaneous class is a module that allows calculation of various 'solution' parameters such as the amount of material required to dissolve in an existing solution to obtain a solution of a given strength or the amount of water to add to a solution of given strength to reduce its strength. Look below for a comprehensive list of the various modules available.
With the latest version, the Miscellaneous Class has been split into Miscellaneous I and Miscellaneous II. In addition, several new modules have been added. These include a Paper module that allows the calculation of various paper measures. Also added are a Metal Hardness, a Mixed Density, A Numbers by Name, a Metric Prefix module, Traffic Marking calculation, and a water vapor permeability module.
Also in the latest version are two new menu items called Find and GoTo. Both of these menu items can be found in the main menu item titled Locate. The Find menu shows a list containing all of the units contained in ProKon that are located in the various unit conversion modules. The list of units is searchable to make it easy to locate a unit in the list. This list of units is useful if you're not sure which module a specific unit might be located in. Selecting a unit from the Find list will take you directly to the module containing that unit. The GoTo menu item shows a list of all of the modules contained in ProKon. The Goto list is also searchable and allows the user to go directly to any module in ProKon, including those modules normally accessed from the Miscellaneous I and Miscellaneous II screens.

Durability Evaluation of Post-Tensioned Concrete Beam Specimens after Long-Term Aggressive Exposure Testing
Author: Turco, G P | Size: 4.24 MB | Format:PDF | Quality:Original preprint | Publisher: University of Texas, Austin | Year: 2007 | pages: 174
This report focuses on the forensic analysis and evaluation of large-scale post-tensioned beam specimens after nearly 8 years of extremely aggressive exposure testing. The research was funded jointly by both the Federal Highway Administration and the Texas Department of Transportation. The relationship between durability performance and the following variables was evaluated in this study: level of applied load and initial cracking, level of prestress, duct type, strand type, grout type, grouting method, use of encapsulated system for anchorage protection, and galvanized duct splice type. In addition, the applicability of half-cell potentials and chloride penetration tests for evaluating the likelihood of corrosion was examined. Major findings were: 1) Mixed reinforcement (also known as partial prestressing) performed poorly from a durability standpoint. Only fully prestressed beams offered better durability performance than those which were not prestressed at all. 2) Corrugated steel galvanized ducts performed very poorly. Large holes were found in the ducts, and in some cases several inches of the ducts completely corroded away. 3) Corrugated plastic ducts offer better performance as long as they are "robust." 4) Non-flowfilled epoxy coated strand and galvanized strand offered no significant improvement in long-term durability over conventional strand. 5) Installing plastic caps over anchorheads rather than just filling the anchorage pocket with nonshrink grout increases the long-term durability of the anchorage.

Prestress Losses in Prestressed Bridge Girders Cast with Self-Consolidating Concrete
Author: Ruiz, Edmundo D Floyd, Royce W Staton, Blake W University of Arkansas, Fayetteville Do, Nam H University of Arkansas, Fayetteville Hale, W Micah University of Arkansas, Fayetteville | Size: 893 KB | Format:PDF | Quality:Original preprint | Publisher: Mack-Blackwell Transportation Center | Year: 2008 | pages: 94
The use of prestressed concrete bridges in Arkansas is becoming more common. The increase in steel costs has contributed to the popularity of prestressed bridge girders. Prestressed girders are particularly common in areas that border neighboring states (and these areas are also typically rural). Self Consolidating Concrete (SCC) is a recent advancement in the concrete industry. SCC is a type of concrete that can be placed without consolidation and is beginning to be widely accepted. Some states are allowing the use of SCC bridge girders. SCC is not much different from conventional concrete. The constituent materials are the same, but SCC typically contains more fine aggregate and cement, but less coarse aggregate. This research program examined the prestress losses of beams cast with SCC and compares those to losses of control beams cast with conventional concrete of the same compressive strength. Additionally, the research program examined the transfer and development length of SCC beams.
