The Formation of the Universe

Until the mid 20th century the view of the world was thought as infinite, had existed for ever and the functions of the world will continue forever. It was believed that the universe has no beginning and no end. However as science and technology progress during the 20th century, the above model has been completely uprooted. Through numerous experiments, observations and calculation conducted by some of the world's most prominent thinkers, modern physics has proven that the universe did indeed have a beginning, that it came into being from nothing in a single moment in a huge explosion.
Furthermore, it has been established that the universe is not fixed and static, as materialists still stubbornly maintain. On the contrary, it is undergoing a constant process of movement, change and expansion. These recently-established facts all act as nails in the coffin of the static universe theory. Today, all these facts are universally accepted by the scientific community.

The origin of the universe is described in the Qur'an in the following verse:
He created the heavens and the Earth from nothing. (Qur'an, 6:101)

As stated earlier, the conclusion that astrophysics has reached today is that the entire universe, together with the dimensions of matter and time, came into existence as a result of a great explosion that occurred a long time ago. This event, known as "The Big Bang," is the catalyst for the creation of the universe from nothingness. This explosion, all parties in the scientific community agree, emanated from a single point some 15 billion years ago.

SCADA

SCADA, Supervisory Control And Data Acquisition, refers to an industrial control system, a system monitoring and controlling a process. SCADA, that’s collects data from various sensors at a factory or remote location and then sends this data to a central computer which manages and controls the data. Now days it is used for wide range of solutions, such as water management systems, electric power, traffic signals, mass transits systems, environment control systems and manufacturing systems.

SCADA system consist of the following subsystems
1. HMI-Human Machine Interface. A system where data is processed and presented to be viewed and monitored by a human operator.
2. RTU- Remote Terminal Unit. Connecting to sensors in the process, converting sensor signals to digital data and sending digital data to the supervisory system.
3. PLC- Programmable Logic Controller. Used as field devices because they are more economical, versatile, flexible, and configurable than special-purpose RTUs.

Nanotube powerd x-rays

Conventional x-ray machines consist of a long tube with an electron emitter, a tungsten filament, at one end and a metal electrode at the other end. The tungsten filament emits electrons when it is heated to 1000 degree Celsius. The electrons are accelerated along the tube and strike the metal, creating x-rays.

Instead of single tungsten emitter, the University of North California (UNC) team uses an array of vertical carbon nanotubes that serve as hundred of tiny electron guns. While tungsten requires times to warm up, the nanotubes emit electrons from their tips instantly when a voltage is applied to them.

A company called Xintek in Research Triangle Park, NC, to commercialize the technology. Xintek has team with Siemens to form a joint-venture company.

Taking clear, high-resolution x-ray images of body organs is much easier with the new multi-beam x-ray source. Conventional computerized tomography (CT) scan machines take a few minutes to create clear 3-D images using x-ray. Because the radiation is coming from one point in space, the machine has to move the [electron] source and detector around the object. The x-ray emitter fires while the tube moves. The motion of the heart and lungs can blur images, so a CT scanner takes hundreds of pictures that are synthesized to reconstruct a 3-D image. It speeds up organ imaging, takes sharper images, and could increase the accuracy of radiotherapy so it doesn't harm normal tissue.

Create .jar file

I developed "Ration Data Entry System" for Sri Lanka Army, during my training at DMS Ltd.
The system developed using java, Oracle and HSQLDB. This project contain so many third party libraries such as iText.jar, Hsqldb.jar, etc...
The Netbeans IDE supports to build the jar files. It creates the jarfiles and MANIFEST but the problem is the classpath for the third part libraries are set to out side thr jar file. I needed just one jar file to deliver the produsct. So follow the following procedure.

1. Created an executable JAR file with the application’s CLASS files in it. Name this “main.jar”
jar cfm main.jar manifest.txt *.class
2. Created three directories: MAIN, LIB, and BOOT
3. Placed “main.jar” file in the MAIN directory
4. Placed the jar files that the main application depends on in the LIB directory
5. Created a new JAR file out of the MAIN and LIB directories. Name this one “application.jar”.
jar cf application.jar main lib
6. Extract the contents of the “one-jar-boot.jar” file into the BOOT directory(one-jar-boot.jar is a third party jar file, can download)
7. Navigated to the BOOT directory, and update the “application.jar” file with the following:
jar -uvfm ../application.jar boot-manifest.mf *.*

My “application.jar” file is now be executable.
It is running when moving the "application.jar" to another directory or another computer too.

done.

HADITH

The Hadith is the record of the sayings of Prophet Muhammad (pbuh). The sayings and conduct of Prophet Muhammad (pbuh) constitute the Sunnah.
The Hadith has come to supplement the Holy Quran as a source of the Islamic religious law. The Hadith is the second pillar after the Quran upon which every Muslim rests his faith. Hadith consists of Mat'n and Isnad. Mat'n means the text of the Hadith, while Isnad means the chain of transmitters to that Hadith.
