The study focused on the use of social networking among secondary school students in Lagos State, Nigeria with implication for academic performance. Specifically, the study determined the relationship between social networking usage and various factors affecting secondary school students who are users of SNSs. The study was strictly restricted to randomly-selected students in public and private secondary schools in Lagos State, Nigeria.
In this paper we presents the bit error rate (BER) performance of the Cyclic Redundancy Check (CRC) coded Long Term Evolution (LTE) system under various digital modulations (BPSK, QPSK and 16PSK) over an additative white gaussian noise (AWGN) and other multi path fading (Raleigh and Rician) channels. It is apparent from the Matlab based simulation study that the proposed LTE system outperforms with BPSK as compared to other modulation schemes under AWGN noisy and Rayleigh and Rician fading channels. The transmitted data is found to have retrieved effectively at the receiver end under the implementation of CRC coding/decoding algorithm. It has been also predictable that the performance of the CRC-based LTE system degrades with the increase of noise power. http://www.scirj.org/rp/items/show/78

The K-500 also offers super-high-sensitivity shooting at a top sensitivity of ISO 51200, allowing the photographer to handhold the camera for beautiful nighttime snapshots.
The street presence is pure Ram 1500. But this engineering goes way beyond muscle and capability. Here, performance is so good, quality is measured in terms of decades.What you see is a dramatic forward-raking grille and sleek exterior — but the story is bigger: This design contributes to reducing air friction and drag. The results? Best-in-class aerodynamics. An honor, to be sure, but one that helps improve fuel consumption, further reduces wind noise, and even helps channel rain and water away from the windshield much more eff ectively.An integral part of the tailgate design, the spoiler also functions to direct airﬂow away from the body — with measurable improvements that help reduce aero drag.Door seals for Ram 1500 off er a triple-play of advantages: They help lock out road noise, create an airtight seal, and boost the interior comfort level.Ram 1500 Laramie Crew Cab shown in two-tone Inferno Red Crystal Pearl and Light Graystone Pearl.

The Advanced Front Air Bags in this vehicle are certified to the new U.S. federal regulations for advanced air bags. Children 12 years old and younger should always ride buckled up in a rear seat. Infants in rear-facing child restraints should never ride in the front seat of a vehicle with a passenger front air bag. All occupants should always wear their lap and shoulder belts properly. No system, no matter how sophisticated, can repeal the laws of physics or overcome careless driving actions. Performance is limited by available traction, which snow, ice and other conditions can affect. When the ESC warning lamp flashes, the driver needs to use less throttle and adapt speed and driving behavior to prevailing road conditions. Always drive carefully, consistent with conditions. Always wear your seat belt. Always look before proceeding, electronic drive aid is not a substitute for conscientious driving, always be aware of your surroundings. Transferable.
