LEARNING DIARY ON IRIS RECOGNITION:

INTRODUCTION:
The reach field on Iris recognition was presented by Jumanne Ally and Robert Mwakajwanga on 12. June. 2009. On this topic have learned a lot of things that was makes me to be interested on it let look first on introduction of iris recognition.
IRIS recognition fall under biometrics authentification the word Biometric refers to the human identification and verification using biological traits, Iris is the muscles within the eye that regulate the size of the pupil and controlling the amount of light that inters the eye.
THE CONCEPT OF IRIS RECOGNITION:
Am very interested for what I have learned by that time the issue of how iris are formed by the presenters present that the iris is formed at the prenatal stage of development of human being , growth through the process of tight forming and folding of the tissue membrane that create the formation of iris to the eye, The iris of the left side and the right part are unique.Athough genetically are identical, an individual irises are unique and structurally recognition.
MECHANISNS OF IRIS RECOGNITON:
It is another part I has learned by that time how iris are recognized or the mechanism before recognition takes place the iris is located into the landmark features then the landmark and distinct shape the allow imaging, features isolation and extraction.
Then iris can recognized by using the special camera for example commercial iris cameras typical use infrared to illuminate the iris without causing harm.
TEST THE STATISTICAL IDEPENDENCE:
To perform recognition, two iris code are compared the amount of two iris code harming distance is used as test of statistical independence between two iris code.
ADVANTAGES AND DISADVANTAGES OF IRIS RECOGNITION:
It is easer I mean in recognition when somebody taken his/her eyes may be for more identification. Not only that since the iris are unique, this ensures maximum security,also identification of persons who have limited use of hands or arms,its stability or template longevity.
Hawever iris recognition although has the advantages also have disadvantages forexample the problem of scanner height adjustment sometimes it failed to take exactly the image requared at the particular time, also the proble of small target, huge system size, the problem cost it is very high cost so that people failed to have such intrument for making iris recognition as individual the last some the usre themselves they don’t have enough skills to use the machine.
CHALLENGES OF IRIS RECOGNITION:
To this part I have learned aloat of the challenges of iris recognition among of them is distance scanning . cost, border control,environmental challeges,high quality image.
CONCLUSSION:
To insure maximum security of our country borders as personal security we should not lie behind this technology. This recognition is especially attractive due to stability of the iris texture pattern.

LEARNING DIARY ON PROGRAMMING/COMPILER:

INTRODUCTION:
Am very interested on the topic, the topic was presented by Kwangu Masalu and Geofrefy. Mhando, the following are terms that I have learned during the presentation for example, Compiler – is a program that converts from some source code (programming language) to machine language. Not only that another thing is Machine Language is the representation of computer program which is actually read and interpreted by the computer while a Program that translates from a low level language to the higher level of language.
THE CONCEPTS OF PROGRAMMING AND COMPILER:
THE HISTORY OF COMPILER
Software for early computers was primary written in assembly language., higher level programming language were not inverted until the benefit of being able to reuse software on different kind of CPU started to become significantly greater than the cost of writing a compiler.
Another thing I have learned during the presentation was different term used in programming and compiler is that Translator A language translator is a type of software that translates a program written in second, third, or higher generation language into machine language, also Interpreters translate source code instructions into machine language and executes it one statement at a time, Syntax and Semantics that is grammar rules and meaning of command.
PROGRAMMING AND COMPILER:
In this topic I have learned three types of programming language. That is Machine languages is a language directly understanding by the machine or computer, therefore it is difficult to modify, it is use computer natural language that is 0sand 1s only, another language is Assembly language and Higher – level languages these two language requiring intermediate translator steps to be well understood by the user, Assembly language is the low level programming language , examples of higher level language is like COBOL, PASCAL,FORTAN …It is allow the users to specify the desired results without having to specify detailed procedures needed for achieving the results.
COMPUTER PROGRAMMING LANGUAGE:
Important for students in all disciplines of computer science that is help to understand well all programs found in different areas that can be learned for example the use of coce to display or getting the output from any source, It increase vocabulary of useful programming language, to make it easier to design and to learn a new language another thing its to make software development, interface writing.
CHALLENGES:
Programming and Compiler also has got challenges for example currently the programming languages are challenging on learning, not only that it needs for skilled programmer to run the difficult programs, it is difficult in debugging.
CONCLUTION: Programming and Compiler this is a good field research to understand because it help the user to understand many things applying on the machine.
