The electric shower will crash the african grid
An electric shower popular in Brazil threatens to strain Africa's electric grid as Africans adopt the technology. In Brazil, electric showers account for 30% of home electricity bills and 18% of peak electricity demand. Kenya wants to ban electric shower sales to avoid overburdening its grid and requires solar water heaters instead. The US monitors hotel guest water usage through wireless systems to encourage conservation.
Solar agricultural applications
If the Brazilian agribusiness accounts for 1/3 of the country's total GDP and 60% of that total is in the farms' post-harvest (we speak of industry, commerce and services), in order to grow Brazil's GDP by 20% in the next six years we will need to double the size of our agribusiness.
And as 60% of it is in industrial transformation and trade, it will not be possible without a strategic agro-industrial revolution

Health & safety on a fiber project in Africa ...
Local subcontractors in Africa did not have strong health and safety (H&S) policies like European vendors. However, foreign mobile investments brought strong H&S policies. Companies are legally required to insure employees and contractors against workplace accidents. To lower insurance costs, companies must enforce H&S policies to prevent employees from intentionally causing accidents. Accidents damage company reputation and management image. Strict enforcement of Vodafone's "6 Absolute Rules" for H&S is required for contractors and vendors in developing countries like Kenya to reduce casualties during fiber installation projects. Adaptations were made to clothing and H&S practices for the local environment and conditions in Mombasa.
Demograhics and the capacity crunch
International bandwidth capacity will be exceeded by 2018 unless infrastructure is improved. Younger generations, known as Millennials, are more likely to use home networks for media like streaming videos and music. Their media orientation drops off significantly with older age groups that instead prioritize work-related network uses. Safaricom has invested in a fiber network called Digital City that will surpass competitors' fiber networks by 2018. Digital City fiber is ready to support high-speed internet and has expanded to more areas than competitors can. This positions Safaricom to stay ahead of increasing bandwidth demand.
Communicating fiber project Enterprise town hall meeting
This document discusses Safaricom's fiber optic program from June 15-16, 2013. It notes that they started slowly but with confidence and have since made progress, with over 71% of the 553.7km fiber optic network now in progress. It lists members of the project team and emphasizes that they have the people and resources to complete the work. It also discusses efforts to engage commercial buildings to help retail fiber capacity and shows examples of buildings that already have fiber connectivity.
Comparison of 3 types of mobile infrastructures
The document compares the infrastructure of three mobile network operators - Orange, YU, and Safaricom - located in the same building in terms of the types of equipment used, space requirements, and impact on the landlord's happiness. YU uses a shelter, generator, and diesel tank taking up roof space, making the landlord very happy. Orange uses rail-mounted racks and antenna-mounted radios on the roof, making the landlord just happy. Safaricom uses wall-mounted radios and Siemens equipment on the first floor, using vacant commercial space and making the landlord extremely happy. It recommends rationalizing space use, clever radio planning to reduce leasing costs, and outsourcing the leasing process

As money shifts to digital providers, investors will fund more providers, causing over-provisioning of networks and applications. For network operators, as devices and applications evolve they will need to continually upgrade their networks to handle more data and access in order to remain relevant in the market.
Nairobi fiber progress report
This document appears to be a report from June 20-21 discussing the burying of fiber infrastructure and related work. It references burying fiber cables, protecting other operators' fiber, continuing trench work, and prioritizing health and safety on the job sites. The report also mentions overtaking competition and connecting businesses in the digital city.
Innovation is easy. The hard part is changing
This document discusses process innovation and challenges the practice of network freezing at the end of the year. It argues that network freezing was invented by equipment vendors to allow their employees to travel home for holidays, and was later adopted by operators for the same reason rather than for technical reasons. However, freezing stalls projects and delays critical work. The document advocates eliminating network freezing and treating fiber connectivity as an essential utility that is prioritized year-round like electricity or water. Customers deserve consistent attention regardless of the time of year.
Trenching for fiber built all over the world
The document lists 13 locations around the world where trenching has been used for fiber optic cable projects, including in the USA, Amsterdam, Holland, Namibe, Angola, Johannesburg, South Africa, a highway in Brazil, the Atacama Desert in Chile, France, Germany, Portugal, and Kenya for the Safaricom Digital City Project.
Fiber to the building is for LTE
Digital City is building fiber infrastructure to support both backhaul and fronthaul for LTE/4G networks. Remote radio heads will be connected via fiber links to distributed base stations. The fiber network is being built out to buildings now to support both backhaul and fronthaul before Safaricom acquires spectrum for a 4G network. The network and core will be optimized based on site geometry to improve latency and move away from legacy landline restrictions.
Safaricom fiber construction after 2 months
Urban and Suburban Africa Metro. Public complained about the construction but after 2 months there was little sign of the works.
Drive down opex leases and rentals
This document discusses the trend toward smaller mobile network equipment that can reduce costs for carriers. It notes that equipment costs have decreased significantly over time, with annual site rental costs now sometimes exceeding the equipment costs. The document also notes projections that using smaller cell sites like picocells and femtocells can result in total capital and operating expense savings of over 100% for U.S. carriers by 2014. It emphasizes the need to educate landlords on this industry trend toward smaller, less expensive equipment that can be installed in more locations like homes and buildings.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Harnessing WebAssembly for Real-time Stateless Streaming Pipelines
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
