Dwarf planet Ceres is the largest object in the asteroid belt between Mars and Jupiter and the only dwarf planet located in the inner solar system.

It was the first member of the asteroid belt to be discovered when Giuseppe Piazzi spotted it in And when Dawn arrived inCeres became the first dwarf planet to receive a visit from a spacecraft.

Called an asteroid for many years, Ceres is so much bigger and so different from its rocky neighbors that scientists classified it as a dwarf planet in Even though Ceres comprises 25 percent of the asteroid belt's total mass, tiny Pluto is still 14 times more massive. Ceres is named for the Roman goddess of corn and harvests. The word cereal comes from the same name.

Size and Distance. If Earth were the size of a nickel, Ceres would be about as big as a poppy seed.

From an average distance of million miles million kilometersCeres is 2. One astronomical unit abbreviated as AUis the distance from the sun to Earth. From this distance, it takes sunlight 22 minutes to travel from the sun to Ceres.

Orbit and Rotation. Ceres takes 1, Earth days, or 4.

Ceres–Negros F.C.

As Ceres orbits the sun, it completes one rotation every 9 hours, making its day length one of the shortest in the solar system. Ceres' axis of rotation is tilted just 4 degrees with respect to the plane of its orbit around the sun.

That means it spins nearly perfectly upright and doesn't experience seasons like other more tilted planets do. Ceres formed along with the rest of the solar system about 4. Scientists describe Ceres as an "embryonic planet," which means it started to form but didn't quite finish.

Nearby Jupiter's strong gravity prevented it from becoming a fully formed planet. About 4 billion years ago, Ceres settled into its current location among the leftover pieces of planetary formation in the asteroid belt between Mars and Jupiter. Ceres is more similar to the terrestrial planets Mercury, Venus, Earth and Mars than its asteroid neighbors, but it is much less dense.The club's home ground is the Panaad Stadium. The club is also a member of the Negros Occidental Football Association.

Negros came from the province of Negros Occidentalwhere the club is based.

Ceres had their first major success in the United Football League in the season, when they won the United Football League Division 2 Championship, earning them promotion to the first division. Ceres is a three-time Philippines Football League champion, and and winner of the Copa Paulino Alcantara Ceres was founded by Leo Rey Yanson.

Initially the club was composed of collegiate players reinforced by Koreans, but eventually it managed to recruit members of the Philippine national team. Following years of successful stints in local football tournaments, the Ceres-La Salle Football Club took another step into competitive football.

Ramon Janeo, one of the team's assistant coaches, confirmed the club's next step to joining the country's premier football league — the United Football League UFL. Ceres dominated the UFL Division 2 as debutante and was promoted to Division 1 the following season. And for one local football observer, considering how the club was very active in recruitment and showed firm commitment to what it wanted to achieve, what it has done, all told, rendered itself not totally surprising.

He said that seeing how Ceres has proven itself as a "game-changer," it puts pressure on the rest of the field to look at their respective teams and assess their competitiveness relative to what Ceres has done and others who may follow suit. They lost to Maziya 1—0. They topped Group E with an undefeated record 3—3—0, chalking up two of their three wins on their own turf. Still, it was a respectable finish for a side that started playing in the United Football League just a couple of years ago.

After earning an outright berth to the group stage for winning the UFL first division last season, the Bacolod side boosted its stock by going unbeaten in Group E that included wins over the Tampines Rovers of Singapore and Sheikh Jamal of Bangladesh. Ceres Negros FC won the match via Penalty shootout The club crest was derived from the main emblem of Ceres Bus Lines. It was encircled in green to represent the colors of University of St. La Salle in Bacolod, which is known for its football team in the university school levels.

The club colors are blue with white trim.

In difference to robust cost functions, they are probabilistically founded and have good convergence properties.

Since their robustness depends on a close approximation of the real error distribution, their parametrization is crucial. We propose a novel approach that allows to adapt a multi-modal Gaussian mixture model to the error distribution of a sensor fusion problem. By applying expectation-maximization, we are able to provide a computationally efficient solution with well-behaved convergence properties.

We demonstrate the performance of these algorithms on several real-world GNSS and indoor localization datasets. The proposed self-tuning mixture algorithm outperforms state of the art approaches with static parametrization. Robotic systems as well as autonomous vehicles require a reliable estimation of their current state and location.

The algorithms that compute these information from sensor data are typically based on probabilistic assumptions. Based on the idea of maximum-likelihood, these problems can be formulated as least squares optimization.

Usually, least squares requires Gaussian distributed measurement errors, which is correct for many sensors and comes with advantageous mathematical consequences for the estimation process.

On the downside, there is a broad range of sensors, like global navigation satellite systems GNSSwireless range measurement or vision-based systems, that violate this assumption. Even simple wheel odometry can slip on difficult grounds and cause non-Gaussian error distributions. These violations can distort the estimation process, leading to false estimates. A variety of approaches exist, that try to achieve robustness against non-Gaussian errors.

But many of these require an exact parametrization and therefore knowledge about the expected error distribution. Previous evaluations [ 34 ] have shown that the optimal set of parameters is hard to find and small deviations can lead to fatal errors. As improvement of the ideas in [ 5 ]we show how to construct an expectation-maximization EM based algorithm that adapt a Gaussian mixture model GMM to the sensor properties.

Due to its graphical possible representation, the least squares problem is also referred to as factor graph. In difference to previous work, we are able to overcome the limitations of the Max-Mixture approximation and implement an exact GMM inside the least squares problem.

This results in a sensor fusion algorithm that is robust against non-Gaussian error distribution without prior knowledge. Through extensive evaluation with real world localization datasets from [ 678 ]we are able to demonstrate its performance in comparison to several state of the art approaches.

Our datasets represent different scenarios from GNSS localization in urban canyons to centimeter-level wireless ranging. To give a short overview of this paper: In Sec. IIwe show how our approach is connected to existing concepts and why we think it surpasses them. III gives an introduction to Gaussian mixture models and how we apply them to least squares optimization.

The EM-Algorithm is briefly described in Sec. IV before we explain our new approach in detail in Sec. VI describes the estimation problems that we solve in our evaluation and Sec.

VII contains the results and their interpretation. Motivated by the simultaneous localization and mapping SLAM problem, several algorithms exit that try to achieve robustness against non-Gaussian outliers. We want to give a brief overview of them and show why existing solutions are often difficult to apply to real world problems. Some of the methods use generic mechanisms to reduce the influence of outliers without knowledge about the true sensor distribution. A typical example are m-estimators, that apply non-convex cost functions to the residual terms of the optimization problem.Ceres was the first asteroid to be discovered by Giuseppe Piazzi at Palermo Astronomical Observatory on 1 January Ceres is the only object in the asteroid belt currently known to be rounded by its own gravity[8] although detailed analysis was required to exclude Vesta.

From Earththe apparent magnitude of Ceres ranges from 6. Ceres appears to be partially differentiated into a muddy ice-rock mantlewith a crust that is 60 percent rock and 40 percent ice [19] or less than 30 percent ice.

Cryovolcanoes such as Ahuna Mons form at the rate of about one every fifty million years. In Januaryemissions of water vapor were detected from several regions of Ceres. Any atmosphere, however, would be the minimal kind known as an exosphere. Johann Elert Bodeinfirst suggested that an undiscovered planet could exist between the orbits of Mars and Jupiter. Bode observed that there was a regular pattern in the size of the orbits of known planets, and that the pattern was marred only by the large gap between Mars and Jupiter.

One of the astronomers selected for the search was Giuseppe Piazzia Catholic priest at the Academy of PalermoSicily. Before receiving his invitation to join the group, Piazzi discovered Ceres on 1 January He announced his discovery on 24 January in letters to only two fellow astronomers, his compatriot Barnaba Oriani of Milan and Johann Elert Bode of Berlin.

The information was published in the September issue of the Monatliche Correspondenz.

By this time, the apparent position of Ceres had changed mostly due to Earth's orbital motionand was too close to the Sun's glare for other astronomers to confirm Piazzi's observations.

Toward the end of the year, Ceres should have been visible again, but after such a long time it was difficult to predict its exact position. To recover Ceres, Carl Friedrich Gaussthen 24 years old, developed an efficient method of orbit determination. On 31 Decembervon Zach and Heinrich W.

Olbers found Ceres near the predicted position and thus recovered it. The early observers were only able to calculate the size of Ceres to within an order of magnitude. Piazzi originally suggested the name Cerere Ferdinandea for his discovery, after the goddess Ceres Roman goddess of agriculture, Cerere in Italian, who was believed to have originated in Sicily and whose oldest temple was there and King Ferdinand of Sicily.

Ceres was called Hera for a short time in Germany. Ceriuma rare-earth element discovered inwas named after Ceres.

The categorization of Ceres has changed more than once and has been the subject of some disagreement. As other objects were discovered in the neighborhood of Ceres, it was realized that Ceres represented the first of a new class of objects.

By the s, the existence of a fundamental difference between asteroids such as Ceres and the major planets was widely accepted, though a precise definition of "planet" was never formulated. The debate surrounding Pluto and what constitutes a planet led to Ceres being considered for reclassification as a planet. Ceres is the largest asteroid in the Main Belt. For example, a news update at Space. It introduces the category of small Solar System bodyas objects that are neither planets nor dwarf planets, and states that they 'currently include most of the Solar System asteroids'.

Lang comments "the [IAU has] added a new designation to Ceres, classifying it as a dwarf planet. By [its] definition, ErisHaumeaMakemake and Pluto, as well as the largest asteroid, 1 Ceres, are all dwarf planets", and describes it elsewhere as "the dwarf planet—asteroid 1 Ceres". Ceres follows an orbit between Mars and Jupiter, within the asteroid belt and closer to the orbit of Marswith a period of 4.AFC Cup. Final Score. Over 1. Over 2. Performance rank. Cup Form.

Found a stat that's worth shouting about?First thing you should know about them is that they aren't designed for high output activities skiing, climbing, cycling, etc. Think of Firebee as a lighter, shorter, more packable, more weather resistant, less warm and a more breathable version of the Ceres. In summary, if packability is almost as important as warmth for you, then the Firebee could be a better option.

If packability is not that important, but still a must have, than the Ceres is more suitable. Both Firebee and Ceres are equipped with fill down highest quality insulation and also supported with synthetic insulation in addition for extra wet weather performance. But the amounts as to how much they're stuffed with them differ, which is an equally important factor that defines the warmth:.
