Watts Line. The Watts Line was a local line of the Pacific Electric Railway that operated between the Pacific Electric Building in Downtown Los Angeles and the Watts Station at 103rd Street in Watts. It was the primary local service for the Southern District, which also included the Long Beach, San Pedro, Santa Ana and Whittier interurban lines. The route operated along the Southern Division's Four Tracks route, with the Watts Line using the outer tracks and the Long Beach line and other limited stop lines using the inner tracks.

History

The local service operated between 1904 and November 2, 1959. The line was quadruple-tracked in 1907. During the 1910s, its service was combined with the South Pasadena Line of the Northern District. From 1938 to 1950, the line was combined with the Sierra Vista Line, which was the main local line in the Northern District. Streetcars were removed and replaced with a parallel bus service on November 2, 1959.

Tracks north of Washington Boulevard were removed or paved over (except a short spur track) after PE service ended. In the late 1980s, the right of way was rehabilitated with one or two tracks used for freight rail (with electrification removed) and two tracks rebuilt to modern light rail specifications. Service along the line between Washington Boulevard and 103rd Street recommenced in 1990 as the Los Angeles Metro Blue Line (renamed the A Line in 2019), with stations at Washington Boulevard, Vernon Avenue, Slauson Avenue, Florence Avenue, Firestone Boulevard, and 103rd Street.

Rogers Dam. Rogers Dam is an earth-filled embankment dam on the Muskegon River in Mecosta Township, Michigan, United States. It is located about  south of Big Rapids. Construction of the dam began in 1905, and its power plant was commissioned in March 1906. Owned and operated by Consumers Energy, the primary purpose of the dam is hydroelectric power generation. On December 22, 1921, the original  power plant was destroyed in a fire. It was rebuilt with an increased  installed capacity in 1922. The rebuild cost approximately $450,000. It is the oldest hydroelectric power plant operated by Consumers Energy, which also owns the Hardy and Croton dams downstream of Rogers Dam.

Consumers Energy has initiated community talks to discuss the future of its 13 hydropower dams, including Rogers Dam.

Schneider Electric DMS. Schneider Electric (full legal name: Schneider Electric doo Novi Sad d.o.o) is a Serbian company that specializes in electricity distribution, automation management and produces installation components for energy management. It is headquartered in Novi Sad, Serbia.

History
The company was founded in 2002 and operated as part of French international company Schneider Electric. According to 2016 media reports, Schneider Electric DMS has close ties with professors at the Faculty of Technical Sciences, and thus has privileged position in graduates recruitment.

In November 2017, it celebrated its 15-year anniversary. In 2019, Schneider Electric acquired the remaining 43% of shares from the minority shareholder "DMS" for an undisclosed sum.

Since 22 May 2012, Schneider Electric founded the Center for Young Talents foundation (), a non-profit non-governmental organization based in Novi Sad whose goals are to contribute to the development of theoretical and practical knowledge in informatics, mathematics and other fields, to contribute to the improvement and practical implementation of the education system in the aforementioned fields, as well as to contribute to the permanent education and training of existing personnel. Originally the programming and math courses were classroom-only, until the 2016/17 school year when the first online classes for mathematics were held (PMUFO). Since 2019/20 school year, over 3,000 classes were held and had 2,881 registered participants on its educational portal.

In July 2021, plans for the new IT building in Novi Sad were revealed. Designed by Zabriskie studio from Belgrade in collaboration with the Novaston Project Management company, the engineering was done by Axisa from Novi Sad.

In June 2023, with the presence of high-ranking officials, the company Schneider Electric opened its new IT center in Novi Sad, called InGrid. This modern office space with an open form, with lots of light and greenery, is interesting because it is located in the reconstructed Užara hall of Novkabel, a former industrial giant under whose auspices the first personal computers were made in the late 1970s and early 1980s in the former Yugoslavia. The 14,500 square meter building is characterized by a carbon-neutral footprint, as well as unique solutions from the Schneider Electric company that provide both power from renewable sources, as well as complete comfort and functionality for work. The building is covered by 1,500 square meters of solar panels that sustain half of the building's annual electrical usage. InGrid was awarded the Platinum LEED certificate for its high ecological sustainability.

Ramesh Govindan. Ramesh Govindan is an Indian-American professor of computer science. He is the Northrop Grumman Chair in Engineering and Professor of Computer Science and Electrical Engineering at the University of Southern California.

Early life
Govindan obtained a Bachelor of Technology degree from the Indian Institute of Technology Madras and then received master's and Ph.D degrees from the University of California, Berkeley. He then became an associate professor at the University of Southern California, where he researches topology, IP forwarding, and wireless sensor networking.

Career
Govindan was later named the Northrop Grumman Chair in Engineering and Professor of Computer Science and Electrical Engineering. He is a former editor-in-chief of the journal IEEE Transactions on Mobile Computing. He is a Fellow of the Institute of Electrical and Electronics Engineers (IEEE) and the Association for Computing Machinery (ACM).

In 2000, he along with Kannan Varadhan and Deborah Estrin analyzed a way to prevent oscillations in topologies. During the study he have discovered that an inter-domain routing protocol called hop-by-hop is responsible for the unconstrained route selection and therefore the route get oscillated. However, if "safe" mode is enabled, it can shorten route selection as well as the number of errors. A year later, he peered up with Deborah Estrin and Deepak Ganesan of UCLA as well as Scott Shenker to develop braided multipath routing scheme which he claimed to be important alternative for energy-saving recovery after lone and patterned failures. On August 14, 2001 he used simulation to evaluate Geographic and Energy Aware Routing protocol and discovered that it lives longer than its non-geographic energy aware routing counterpart.

In 2002, he and colleagues from both International Computer Science Institute and UCLA have developed a geographic hash table which was later used along with data-centric storage system. In 2004, while working with researchers at the University of California, Los Angeles he discussed wireless sensor network system which is called Wisden which according to him and his colleagues will use end-to-end and hop-by-hop transport recovery which wouldn't require global clock synchronization to transport data. During the same study they have developed wavelet-based technique that will use limited amount of data bandwidth for low-power wireless radios.

In 2006, Govindan and his colleagues have developed a compact version of a pursuit–evasion application called Tenet. In 2010 Govindan, Jeongyeup Paek and Joongheon Kim used smartphones to evaluate remote area power supply. He and his colleagues found that this prototype implementation increased phone lifetimes 3.8 times more than GPS.

Lancang River Railway Bridge. The Lancang River Railway Bridge is an arch bridge under construction od Dali-Ruili Railway near city of Baoshan in western Yunnan Province, China. Once completed, the bridge will be one of the highest in world, sitting  above the Lancang River. The bridge's main span will be  making it also one of the longest arch bridges ever built. The bridge is expected to be completed in 2022.

Design 

Instead of using cable stays and tiebacks to build the arch, the two steel truss arch halves were built vertically on either side of the canyon slopes on top of scaffolding. While still in a vertical position, the two halves were then lowered over the gorge where they were connected at the crown. The total length of the bridge is 698 meters.

Site 
The site showcases three high spans including an older suspension bridge, the new railway bridge and a high pipeline suspension bridge that is the third-highest of its type in the world after the Hegigio Gorge Pipeline Bridge in Papua New Guinea and the Niouc Bridge in Switzerland.

The official height of the bridge is 271 meters, measured to the river's original surface. The construction of the Xiaowan Dam downstream created a reservoir that extends back under the bridge and raised the water level some 50 meters.
