CU-Boulder Offers Teachers, Students Hands On Forensics Experience

first_img Published: Jan. 31, 2001 Share Share via TwitterShare via FacebookShare via LinkedInShare via E-mail Teachers and students from elementary and middle schools along the Front Range will descend on the University of Colorado at Boulder Feb. 6 to become forensic scientists for a day. The 105 students and 21 teachers from 12 different schools will participate in a series of hands-on workshops at the Coors Events/Conference Center designed by CU’s Science Explorers. “The purpose is to give teachers and students in fifth through eighth grades a day of hands-on science, and to hopefully make science fun for them,” said Lannie Hagan, Science Explorers coordinator. Twenty-one teams, each comprised of one teacher and five students, will investigate the “Who Stole the Bones?” mystery throughout three different workshops, according to Hagan. The workshops include an anthropology investigation, a fingerprinting experiment and a lesson in DNA testing, Hagan said. At the end of the day, students and teachers will receive kits to take back to their classrooms and reconstruct the day’s experiments for other students. “The goal is that at the end of the day students and teachers will be able to go back and teach the other kids what they learned,” Hagan said. The Science Explorers program conducts 22 theme-oriented workshops a year. The group holds some workshops at CU and travels to more than 15 schools throughout the state.

A new set of M&A rules in its home market could also see Bharti in the market for acquisitions.On the other hand, the group has $9.3 billion in debt, largely linked to its acquisition of Zain’s African unit four years ago. Cash generated from the tower sales could therefore be used to improve its balance sheet.Bharti took full control of the mobile operations in Bangladesh last year when it acquired a 30 per cent stake held by Warid Telecom. At the end of the fourth quarter, Airtel Bangladesh had 8.3 million connections, according to GSMA Intelligence estimates.The group is believed to have previously received separate offers for its tower networks in Bangladesh and Africa. Bharti expects to generate $1.5 billion to $1.8 billion by selling its network of 15,000 towers in Africa, according to The Economic Times.Bharti previously raised money from its tower assets with an IPO of its Bharti Infratel unit in December 2012.

Solei leads Gophers to 5-1 win over Wayne State

first_imgSolei leads Gophers to 5-1 win over Wayne State Brian DeutschJanuary 4, 2008Jump to CommentsShare on FacebookShare on TwitterShare via EmailPrintThree-and-a-half years worth of rust shook off pretty quick as senior net-minder Brent Solei led the Minnesota men’s hockey team to a 5-1 win over Wayne State in his first regular season start.“It feels great just to get the win,” Solei said after the game. “It was pretty emotionalÖI had a lot of fun out there.”The senior from Coon Rapids made 28 saves and earned the game’s First Star as well the Heart of the Game award.When the latter was announced, the crowd of 9,915 gave the walk-on a standing ovation. But as much as Solei impressed fans, he left the biggest impression on his coach.“Based on how he played tonight, he earned the right to maybe get another opportunity,” coach Don Lucia said. “I’m not saying that that’s going to happen, but he certainly has put himself into the mix.”Lucia cited Solei’s team leading save percentage albeit it is averaged from just two games.The ninth year coach wouldn’t say who would be in net tomorrow night, although Solei said he expected to be on the bench.At the start of tonight’s contest, it didn’t look as though Solei would be tested much, the Warriors didn’t put a shot on goal until the 7:23 mark of the first period.But Wayne State would eventually find its stride and even tied the game at 1-1 in the second period.After the Gophers unsuccessfully tried to clear the puck out of their own zone, sophomore defenseman Ryan Bernardi found sophomore winger Jared Katz wide open behind the Minnesota defenseman.Katz had plenty of time to deke Solei and put his fourth goal of the year through the Gophers’ goalie’s five-hole. “I saw it coming in and I tried to sit there as long as I could and be patient,” Solei said.Nevertheless, the goal brought the senior’s save percentage down to .966, substantially ahead of freshman Alex Kangas’ .912 and senior Jeff Frazee’s .891.But that was all Solei would allow all night, and a relatively close game was blown wide open by three Minnesota goals in the third period.Offensively, the Gophers had four skaters with two points a piece and junior forward Blake Wheeler and senior forward Ben Gordon, one and two on the team in points respectively, each had a goal in the game. Gordon’s was the eventual game winner.“It was definitely an emotional win tonight,” senior forward Evan Kaufmann said.Kaufmann, who started the third period scoring blitz with his third goal of the year, said he too was impressed by his classmate’s play.“I think everyone was ecstatic that Brent got the win tonight. Not only did he win, he played pretty phenomenal,” Kaufmann said. “I don’t think it would have been a 5-1 game if we didn’t have Brent in the net.”Game Notes-Minnesota put a season high 51 shots on goal tonight.-Warriors’ freshman net-minder Mike Devoney also made his regular season debut tonight in relief. He made ten saves in the third period and allowed one goal.1 2 3 Final Minnesota 0 2 3 5 Wayne State 0 1 0 1 Scoring: First ñ 1. No Scoring Second ñ 1. MN, Wheeler (Pohl), 2:51 (SH). 2.

CMOS RF Circulator Chip Doubles WiFi Capacity

first_imgResearchers at Columbia Engineering have developed a technology for full-duplex radio integrated circuits (ICs) that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception at the same frequency in a wireless radio. Last year, the researcher had developed a nanoscale CMOS radio that required two antennas, one for the transmitter and one for the receiver. Now, the team, led by Electrical Engineering Associate Professor Harish Krishnaswamy, has developed a breakthrough technology that needs only one antenna, thus enabling an even smaller overall system. This is the first time researchers have integrated a non-reciprocal circulator and a full-duplex radio on a nanoscale silicon chip.This technology could revolutionize the field of telecommunications. Systems with seperate Tx and Rx antennas can now operate using a single antenna and systems based on WiFi will see capacity double using a nanoscale silicon chip with a single antenna.This group has been working on silicon radio chips for full duplex communications for several years and became particularly interested in the role of the circulator, a component that enables full-duplex communications where the transmitter and the receiver share the same antenna. In order to do this, the circulator has to “break” Lorentz Reciprocity, a fundamental physical characteristic of most electronic structures that requires electromagnetic waves travel in the same manner in forward and reverse directions.Reciprocal circuits and systems are quite restrictive as you can’t control the signal freely. The traditional way of breaking Lorentz Reciprocity and building radio-frequency circulators has been to use magnetic materials such as ferrites, which lose reciprocity when an external magnetic field is applied. But these materials are not compatible with silicon chip technology, and ferrite circulators are bulky and expensive.They were able to design a highly miniaturized circulator that uses switches to rotate the signal across a set of capacitors to emulate the non-reciprocal “twist” of the signal that is seen in ferrite materials. Aside from the circulator, they also built a prototype of their full-duplex system—a silicon IC that included both their circulator and an echo-cancelling receiver—and demonstrated its capability at the 2016 IEEE International Solid- State Circuits Conference in February.Non-reciprocal circuits and components have applications in many different scenarios, from radio-frequency full-duplex communications and radar to building isolators that prevent high-power transmitters from being damaged by back-reflections from the antenna. The ability to break reciprocity also opens up new possibilities in radio-frequency signal processing that are yet to be discovered. Full-duplex communications is of particular interest to researchers because of its potential to double network capacity, compared to half-duplex communications that current cell phones and WiFi radios use. To further improve the performance of their circulator, and exploring “beyond-circulator” applications of non-reciprocity, work is already going on.This group was able to demonstrate a practical RF circulator integrated with a full-duplex receiver that exhibited a factor of nearly a billion in echo cancellation, making it the first practical full-duplex receiver chip and which led to the publication in the 2016 IEEE ISSCC.The work has been funded by DARPA MTO (Microsystems Technology Office) under the ACT (Arrays at Commercial Timescales) and the RF-FPGA programs, and by the National Science Foundation (ECCS-1547406).last_img read more

Colin Greig takes golfer of the month award

first_imgThe temperature wasn’t the only challenge as gale force winds added to the misery.  Well, maybe unpleasant is a better word but, in any case, very unusual conditions for golf in Fun City.How does the saying go …”when the going gets tough, the tough get going”?  Well, you couldn’t get much tougher than our gimpy bandit, Tony Scambler, or our newly crowned silver bird, Alex Kilcoyne.  Playing through the cold, blustery conditions both men managed to better their handicaps by five and four strokes respectively – a really fine performance in spite of the weather.A-Flight1st Tony Scambler (12) 41pts2nd Dave Ashman (17) 34pts3rd Gordon Melia (17) 33ptsB-Flight1st Alex Kilcoyne (27s) 40pts2nd P.J.
