Extended Kalman filter
In estimation theory, the extended Kalman filter (EKF) is the nonlinear version of the Kalman filter which linearizes about an estimate of the current mean and covariance. In the case of well defined transition models, the EKF has been considered the de facto standard in the theory of nonlinear state estimation, navigation systems and GPS.

Estimation theory
Estimation theory is a branch of statistics that deals with estimating the values of parameters based on measured empirical data that has a random component.  The parameters describe an underlying physical setting in such a way that their value affects the distribution of the measured data. An estimator attempts to approximate the unknown parameters using the measurements.
In estimation theory, two approaches are generally considered:

The probabilistic approach (described in this article) assumes that the measured data is random with a probability distribution dependent on the parameters of interest

The set-membership approach assumes that the measured data vector belongs to a set which depends on the parameter vector.
Maiorske
Maiorske (Ukrainian: Майо́рське) is a village in Ukraine, located in Zakharivka settlement hromada, Rozdilna Raion, Odesa Oblast. In 2001, it had a population of 391.

It was founded in 1791. Until 1947, the village was known as Shepterediury (Ukrainian: Шептередюри; Romanian: Șapte Rediuri). It was located in Zakharivka Raion until 17 July 2020, when that raion was merged into Rozdilna Raion in accordance with nationwide administrative reforms.

The Shepteredy landscape reserve - named after the former name of the village - is located nearby, near the border with Moldova.

Zakharivka Raion
Zakharivka Raion (Ukrainian: Захарівський район); (Russian: Захаровский район), until May 2016 Frunzivka Raion (Ukrainian: Фрунзівський район, Frunzivskyi raion); (Russian: Фрунзовский район, Frunzovskyi raion), was a raion (district) in Odesa Oblast in southwestern Ukraine. The administrative center of the raion was the urban-type settlement of Zakharivka. According to the 2001 census, the majority of the Frunzivka district's population spoke Ukrainian (92.09%), with Romanian (4.07%) and Russian (3.22%) speakers in the minority. The raion was abolished and its territory was merged into Rozdilna Raion on 18 July 2020 as part of the administrative reform of Ukraine, which reduced the number of raions of Odesa Oblast to seven.  The last estimate of the raion population was 19,824 (2020 est.).

On 19 May 2016, Verkhovna Rada adopted decision to rename Frunzivka to Zakharivka and Frunzivka Raion to Zakharivka Raion conform to the law prohibiting names of Communist origin.
Hibbertia vestita
Hibbertia vestita, commonly known as hairy guinea-flower, is a species of flowering plant in the family Dilleniaceae and is endemic to eastern Australia. It is a small shrub with foliage covered with simple hairs, usually linear leaves, and yellow flowers with 22 to 43 stamens with many staminodes arranged around three hairy carpels.

Staminode
In botany, a staminode is an often rudimentary, sterile or abortive stamen, which means that it does not produce pollen.  Staminodes are frequently inconspicuous and stamen-like, usually occurring at the inner whorl of the flower, but are also sometimes long enough to protrude from the corolla.

Sometimes, the staminodes are modified to produce nectar, as in the witch-hazel (Hamamelis).

Staminodes can be a critical characteristic for differentiating between species, for  instance in the orchid genus Paphiopedilum, and among the penstemons.

In the case of cannas, the petals are inconsequential and the staminodes are refined into eye-catching petal-like replacements.

A spectacular example of staminode is given by Couroupita guianensis, a tropical tree growing in South America also known as the cannonball tree.

Teknikum
Teknikum is an upper secondary school (in Swedish called gymnasieskola) located in Växjö, Sweden.

The school was founded in 1961 as an engineering school, offering three-year programs in mechanical, chemical, electrical and construction engineering, with an optional fourth year providing the degree of gymnasieingenjör. Although the latter was a professional degree (awarded until 1992), a large share of the students continued their education at university level, e.g. as Master of Science in Engineering.

Since the 1990s the focus on engineering has diminished, and the school offers a wide range of secondary level educational programs.

The building itself has been commonly referred to as “the prison” due to its architectural style and has been regarded by the locals of Växjö and others from Småland as the ugliest building in Småland

Master of Science in Engineering
A Master of Science in Engineering (MSE) is an academic graduate degree awarded by universities in many countries. It is differentiated from a Master of Engineering (a professional degree). A MSE can require completion of a thesis and qualifies the holder to apply for a program leading to a Doctor of Philosophy (often abbreviated PhD or DPhil) in engineering, while a Master of Engineering can require completion of a project rather than thesis and usually does not qualify its holder to apply for a PhD or DPhil in engineering science.

The MSE is considered equivalent to diplom degree in engineering in the countries that do not have a specific distinction between MSE and Master of Engineering.

In the UK the MEng is an extended undergraduate degree, and the MSc is a one year postgraduate degree for those who already have a BEng. They both contribute to obtaining a chartered engineer qualification.

Currently, the main limited-overs county competitions are the One-Day Cup, Women's One-Day Cup, T20 Blast and Women's T20 Blast.
