Back in 2009, human rights activist, Natalia Estemirova, was found murdered as she was working on "extremely sensitive" cases of human rights abuses in Chechnya during armed conflicts in the republic and the North Caucasus region. After her death, the Civil Rights Defenders -- an independent expert organization in Stockholm that aims to defend people's civil and political rights -- launched the Natalia Project in the spring of 2013...
Back in 2009, human rights activist, Natalia Estemirova, was found murdered as she was working on “extremely sensitive” cases of human rights abuses in Chechnya during armed conflicts in the republic and the North Caucasus Before her death, Estemirova documented and reported on human rights violations; such as forced disappearances, extrajudicial killings, and torture.
While the cloud promises to reduce enterprise network infrastructure and operating costs, the remote execution of applications makes factors such as latency, performance, and reliability critical considerations in the design and deployment of cloud computing platforms. A key factor determining server performance, cloud or not, is maintaining a bit error rate (BER) on the order of 1.E-12 for the overall system.
System-Level Design and Verification of Wireless Embedded System to Meet Global Demands Using a Mixed Domain OscilloscopeMay 28, 2013 3:15 pm | by Faride Akretch, Technical Marketing Manager, Tektronix | Articles | Comments
Designing and implementing wireless systems to be used in different geographic regions around the world represents a significant challenge. Wouldn’t it be nice if everyone all agreed on the use of frequency, modulation type, power levels, and bandwidth? Unfortunately, that’s not the world we live in and radio regulations vary from region to region, especially for some of the frequencies used in unlicensed radio...
The fiber optics market has experienced a significant increase in demand over the last decade, largely driven by the rise, availability, and affordability of sophisticated portable electronics, such as mobile phones, tablets, and laptops. These devices have accelerated global connectivity, simultaneously driving the need for a fast and reliable Internet infrastructure.
With cellular phones becoming not just voice, but now also data appliances, there is a growing need for operators to provide wide area (3-5 mile) coverage that assures high-rate data and voice services in nearly every location. What used to be considered “acceptable” gaps in coverage, like isolated homes...
The era of the Internet began in 1980s by networking organizations like the military, government agencies, corporate, and universities. If we talk to any user from that time, they wouldn’t have the slightest clue of what the future of this technology would be.
When it comes to new applications and overall potential for a given technology, not much rivals the integration of wireless sensor networks (WSN). Reader feedback regarding new WSN applications, trends, and obstacles essentially provided a snapshot of the wireless design marketplace as a whole...
For the adventurers, explorers, and extreme athletes, getting the perfect shot or photo can be quite cumbersome with a regular, hand-held camera or camcorder; especially when both hands are needed to maneuver a certain situation or action. New York start-up, Pivothead ...
Digitally modulated signals fill space and travel through almost every wired and optical network. Today, almost all wireless services use a plethora of complex carrier modulation schemes. The continuous improvement in modulation technologies, components, and advancements ...
When Charles Babbage prototyped the first computing machine in the 19th century, he imagined using mechanical gears and latches to control information. ENIAC, the first modern computer developed in the 1940s, used vacuum tubes and electricity.
Mobility continues to be the hottest trend for the semiconductor and electronics industry. As though there were any need for supporting data, the major electronics shows from the first quarter of 2013 displayed and demoed the latest array of mobile devices.
Amidst the much-discussed love affair between consumers and their mobile devices, another relationship is blooming in the mobile sector. Device manufacturers from nearly every vertical industry are increasingly offering devices and products equipped with mobile connectivity, transforming “dumb” devices into “smart” ones.
OMRON’s MEMS switch has a SPDT（Single Pole Double Throw） contact configuration. Two MEMS chips that have a SPST (Single Pole Single Throw） contact configuration are installed on the ceramic package using the flip chip bonding method as shown Figure 1.
There's no question that LTE is where it's at if you're an operator. According to a recent report from 4G Americas, more than 150 operators globally have now launched LTE services in 67 countries, 50 of which were launched in the past five months.
New technologies that exploit quantum behavior for computing and other applications are closer than ever to being realized due to recent advances, according to a review article published this week in the journal Science. These advances could enable the creation of immensely powerful computers...
When handling electronics repairs, upgrades, or returns, including forward or reverse logistics, cycle time matters. The impact of slower cycle time is often felt on cost, such as when viable circuit boards or other parts are unnecessarily replaced when they can be repaired.
Sensors have become a regular feature in many systems. They reside alongside numerous other peripherals to add to the range of environmental inputs that can be incorporated into the job being done by the system. However, in some systems, the number of sensors threatens to overwhelm the other more traditional peripherals.
Power has come of age as a defining parameter in electronic systems. Whether maximizing battery life, keeping an enclosure cool, or passing large currents more efficiently, projects now start with power in mind. In 2013 we will see the continued migration of power technologies from research to commercial availability.
In the popular imagination, satellites are imperiled by impacts from ‘space junk’ – particles of man-made debris the size of a pea (or greater) that litter the Earth’s upper atmosphere – or by large meteoroids like the one that exploded spectacularly over Chelyabinsk, Russia last week.
This week on WDD's Hotspot, brought to you by Memory Protection Devices, ASUS releases a pocket router; Oxford University creates an autonomous navigational system; and CA-based Second Sight receives U.S. market approval from the FDA; and MIT develops a processor chip.
For test equipment manufacturers and their customers, one trend is unavoidable: the deepening integration of the RF, microwave and high-speed digital technologies used inside today’s electronic systems, especially mobile devices. To satisfy end-user demand for always-on access and fast data rates, mobile devices need powerful processing capabilities.
You are ready and packed to leave on a holiday trip and for the first time, you agreed that your teenage son can stay home alone. The control freak in you is already making long lists of daily and weekly tasks and to-do’s to keep the pets and plants alive, and the calamity predictor in you wants to anticipate for flooded bathrooms and burning fryers.
LTE is no longer the future of telecommunications; it is now a key component of the network’s infrastructure. Service providers are investing heavily in this technology to meet customer demand as consumers continue to purchase smart phones, tablets and other wireless devices at unprecedented rates.
