A generator matrix for a linear [,,]-code has format , where n is the length of a codeword, k is the number of information bits (the dimension of C as a vector subspace), d is the minimum distance of the code, and q is size of the finite field, that is, the number of symbols in the alphabet (thus, q = 2 indicates a binary code, etc.).
A low-flush toilet (or low-flow toilet or high-efficiency toilet) is a flush toilet that uses significantly less water than traditional high-flow toilets. Before the early 1990s in the United States, standard flush toilets typically required at least 3.5 gallons (13.2 litres) per flush and they used float valves that often leaked, increasing their total water use.
Convolutional code with any code rate can be designed based on polynomial selection; [15] however, in practice, a puncturing procedure is often used to achieve the required code rate. Puncturing is a technique used to make a m/n rate code from a "basic" low-rate (e.g., 1/n) code. It is achieved by deleting of some bits in the encoder output.
A common combination for dual-flush toilets meeting the WaterSense standard is a reduced flush of 1.1 US gallons (4.2 L) and a full flush of 1.6 US gallons (6.1 L). [18] [19] Dual flush mechanisms are also more likely to develop leaks than a traditional siphon; the UK supplier Thames Water claimed in 2020 that dual flush toilets were likely to ...
EPACT92 was far reaching in the impacting electric power deregulation, building codes and new energy efficient products. The act was also responsible for the mandate of low flush toilets and outlawing the installation of toilets that flushed more than 1.6 gallons (6 liters) of water.
By Deborah Mary Sophia. (Reuters) -Texas Instruments said on Friday it would receive up to $1.6 billion in funding from the U.S. Commerce Department towards the construction of three new ...
The amount of water used by conventional flush toilets is usually a significant portion of personal daily water usage: for example, five 10 L (2.6 US gallons) flushes per day use 50 L (13 US gallons). Modern low-flush toilet designs allow the use of much less water per flush, 4.5 to 6 L (1.2 to 1.6 US gallons) per flush. [citation needed]
In the United States, Older conventional toilet models, typically those built before 1982, can use 5 to 7 gallons of water per flush. Toilets from the era of 1982-1993 may use a somewhat smaller 3.5 gpf. Modern washdown and symphonic variant standard flush toilets in the United States use 1.6 gpf or 6 lpf (liters per flush). [11]
