Image Sorter

At GNoor PCtronics, we have recently tested our algorithm to sort images stored in 'image bank'. Every time, it reshuffle each image randomly. There is ABSOLUTELY no chance of repeatability and/or missing pigeon hole on the canvas. However there are certain simple easy to follow rules for images to be stored in 'image bank'. Among other things, dimensional size of image should be in multiples of 10 pixels. Therefore, smallest image size could be 10x10 pixel, or the largest image could be 300x300 pixels.

Algorithm worth only USD 1,200

Eid Mubarak (1432)

Eid ul-Fitr or Id-ul-Fitr, often abbreviated to Eid, is a respectful, remarkable and honorable festival day celebrated with dignity at the end of Mah-e-Ramadan, the Islamic holy month of fasting. Eid is an Arabic word meaning "festivity", while Fiṭr means "charity" (and can also mean "nature", from the word "fitrah"); and so the holiday symbolizes the breaking of the fasting period. It is celebrated after the the end of the Islamic month of Ramadan, on the first day of Shawwal. The Takbir is recited after having confirmation that the moon of Shawwal is sighted on the eve of the last day of Ramadan. It continues until the start of the Eid prayer. Before the Eid prayer begins, every Muslim who is able must pay Zakat al-fitr, an alms for the month of Ramadan. This equates to about 2 kilograms (4.4 lb) of a basic foodstuff (wheat, barley, dates, raisins, etc.), or its cash equivalent, and is handed over to people who deserves it. This is distributed to needy local Muslims prior to the start of the Eid prayer. It can be given at any time during the month of Ramadan and is often given early, so the recipient can use it for Eid purchases. This is distinct from Zakat based on wealth, which must be paid to a worthy charity. The Takbir consists of:

Allaahu Akbar, Allaahu Akbar, Allaahu Akbar La ilaaha illAllaah Allaahu Akbar, Allaahu Akbar wa Li-illaahil-Hamd.

Allah is the Greatest, Allah is the Greatest, Allah is the Greatest, There is no deity but Allah, Allah is the Greatest, Allah is the Greatest and to Allah goes all praise.

Remember every one on this very special day.

While Prof. Dr. Altaf Mukati share his Electronic Work-Bench memoirs with Mr Rafiq when it comes to speak on electronic simulation.

Later, Mr Ahmed Bilal and Mr Elie explained NI scope of work with respect to simulation, emulation, mechatronics, and robotics. All these were focused on education. How NI has been working with different educational societies all around world. Specifically working with MIT is explained and a video is played for audience to get some know-how on NI Academic activities.

After a short break, we returned to listen Dr Bhawani Shanker DEAN, MUET.

He presented his article “Project-Based Learning”. Dr Bhawani speaks his article, and shares his experience for PBL. He focused his concerns that a student, educators and organizations who facilitate an educational institute would work together to resolve real-world problem using a generalized concepts of PBL as practiced by other countries.

Finally, we arrived to get knowledge of NI Elvis.

The Elvis, and other related NI products is presented by Mr. Elie Abou Nasr, Manager Middle East NI and Ahmed Bilal, NI Pakistan. Mr Elie says that NI is always ready to work with educational sectors to provide more intelligent and cost-effective solution to equip their technical laboratories so students can get hands-on experience on real-world problems with minimum efforts and without any resources wastage as normally it happen with industries. NI Elvis with LabVIEW, a student can do all practical for what they learn in theory.

Chief Guest Prof. Dr. Muhammad Aslam Uqaili concluded the seminar with his most appreciable and intellectual remarks. At this occasion, “Ajrak” presented by Rafiq Ahmed Lakhani to Dr Muhammad Aslam Uqaili and to Elie Abou Nasr.

People from educational sectors contribute a good comments and express their feelings about this event. While, several other attendees from non-educational sectors also add their statement regarding the real-world challenges that can be easily solved using Elvis & LabVIEW.

We, GNoor PCtronics appreciate such events and foresee a good learning environment not only for students but for industrial engineers as well. We are more convinced by Mr Elie Abou Nasr, that these tools, like Elvis can be utilized in industries to solve complex problems without investing huge resources.

We all are working together to get a better tomorrow.

When 24x7x365 basis electrical operation is required, users must arrange appropriate control unit to keep their operation alive & active. High Tech equipments are designed to operate without interruption; infrastructure usually doesn't support such rigorous dependability. Among other supporting equipments, Air Conditioners are supposed to work on regular basis to maintain an ideal working temperature. As Air Conditioners FAIL, room temperature will raise the above rated value creating problems for equipments operating inside the room.

SOLUTION; What's needed is an intelligent approach to these environmental measurement & control to improve work flow and performance of high tech equipment implanted inside a packed room that protects an unrealistic workload on supervisors and site engineers. REDAC upload climate data to your web server over GPRS using standard HTTP, TCP, UDP protocols. It is designed to offer rapid application development board to collect room environment data from remote locations without spending extra resources on off-line method to collect data for geographically dispersed locations. A fail-safe micro controller, semiconductor temperature & humidity sensors, electrical power sensors GPS/GSM/EDGE engine and an intelligent multi-chemistry battery charger with dual power supply inlets, and automatic cut-off mechanism to avoid rechargeable battery deep discharge is all implemented on highly cost-effective data acquisition device named “REDAC-E457”.

Crystal Oscillator

http://www.GNoorPCtronics.com/updates/OSCheck.pdf

An oscillator is an electronic device used for the purpose of generating a signal. Oscillators are found for example in computers, wireless receivers and transmitters, and audio-frequency equipment, and music synthesizers. Every oscillator has at least one active device.This active device acts as an amplifier.There are many types of oscillator devices, but they all operate according to the same basic principle: an oscillator always employs a sensitive amplifier whose output is fed back to the input in phase. Thus, the signal regenerates and sustains itself. This is known as positive feedback. Crystal oscillators are oscillators where the primary frequency determining element is a quartz crystal. Because of the inherent characteristics of the quartz crystal the crystal oscillator may be held to extreme accuracy of frequency stability. Crystal oscillators are usually, fixed frequency oscillators where stability and accuracy are the primary considerations.Temperature compensation may be applied to crystal oscillators to improve thermal stability of the crystal oscillator. The value of feedback resistor and capacitor determines the stability of oscillation with respect to crystal. Use formula R:= 1/(2Pi*F*C) Where F is frequency, C is capacitance in Farad.
The selection of feedback resistor and capacitor is very critical, it is often found that oscillator does not work.
