This document provides information about performing glass replacement for Mercedes-Benz vehicles. It discusses several reasons why independent shops should offer glass replacement services instead of outsourcing the work, such as maintaining control over customer relationships and responsibility for repairs. It also emphasizes the importance of using genuine Mercedes-Benz Star-Marked replacement glass, which is made to the same high specifications as original equipment and helps maintain the vehicle's structural integrity. The document also introduces a tool called the Roll Out tool that allows safe and damage-free removal of glass.

Building Custom ML PipelineStages for Feature Selection with Marc KaminskiSpark Summit
For predicting vehicle defects at BMW, a machine learning pipeline evaluating several thousand features was implemented. As important features can be useful for evaluating specific defects, a feature selection approach has been used. For further evaluating the importance of features, several feature selection techniques (filters and wrappers) have been implemented as ml PipelineStages for usage on dataframes for incorporation in a complete Spark ml Pipeline, including preprocessing and classification. The general steps for building custom Spark ml Estimators are presented. The API of the newly implemented feature selection techniques is demonstrated and results of a performance analysis are shown. Besides that, experiences gained and pitfalls that should be avoided are shared.

"Of course, you prefer to take players who are fully fit, but that's okay. We want to wait and be patient for some players even if they cannot play in those first matches," he told a press conference. The 37-year-old Vertonghen, Belgium’s Euro Cup 2024 most-capped international with 154 appearances, is struggling to shake off a groin injury.
"He will be there normally. This also applies to Youri Tielemans and Arthur Theate. The latter's position is very sensitive. We don't have many choices at left back. "It will only change if it turns out that they will only be available when, say, the final of the Euro 2024 Championship comes around. That's too long to wait.

Belgium vs Romania: Radu Dragusin Prepares for Crucial Role in Euro Cup Germany
Some of them have taken not one but two steps forward in their rehabilitation," he said. None of the injured players will feature in this week’s warm-up friendlies against Montenegro and Luxembourg. Romania centre-back Radu Dragusin found chances limited at Tottenham Hotspur in the second half of the 2023-24 season.
But is crucial to his country's cause at UEFA Euro 2024 where his aerial ability, physicality and hard graft make him a standout player. The 22-year-old moved to North London from Italian side Genoa in January but was kept on the sidelines by the form of another new arrival for the season, Mickey van de Ven, something Romania coach Edward Iordanescu admitted was a concern.
It will mean limited game-time going into the finals, but Dragusin, who cites Netherlands defender Virgil van Dijk as a role model, started every Euro Cup Germany qualifier as Romania went through the campaign unbeaten in their 10 games. He will be among their most important players in their first game in Germany against Ukraine in Munich on June 17, taking the right centre-back role in what is likely to be a back four.

Narrated Business Proposal for the Philadelphia Eaglescamrynascott12
Slide 1:
Welcome, and thank you for joining me today. We will explore a strategic proposal to enhance parking and traffic management at Lincoln Financial Field, aiming to improve the overall fan experience and operational efficiency. This comprehensive plan addresses existing challenges and leverages innovative solutions to create a smoother and more enjoyable experience for our fans.
Slide 2:
Picture this: It’s a crisp fall afternoon, driving towards Lincoln Financial Field. The atmosphere is electric—tailgaters grilling, fans in Eagles jerseys creating a sea of green and white. The air buzzes with camaraderie and anticipation. You park, join the throng, and make your way to your seat. The stadium roars as the Eagles take the field, sending chills down your spine. Each play is a thrilling dance of strategy and skill. This is what being an Eagles fan is all about—the joy, the pride, and the shared experience.
Slide 3:
But now, the day is marred by frustration. The excitement wanes as you struggle to find a parking spot. The congestion is overwhelming, and tempers flare. The delays mean you miss the pre-game excitement, the tailgate camaraderie, and even the opening kick-off. After the game, the joy of victory or the shared solace of defeat is overshadowed by the stress of navigating out of the parking lot. The gridlock, honking horns, and endless waiting drain the energy and joy from what should have been an unforgettable experience.
Our proposal aims to eliminate these frustrations, ensuring that from arrival to departure, your experience is extraordinary. Efficient parking and smooth traffic flow are key to maintaining the high spirits and excitement that make game days special.
Slide 4:
The Philadelphia Eagles are not just a premier NFL team; they are an integral part of the community, hosting games, concerts, and various events at Lincoln Financial Field. Our state-of-the-art stadium is designed to provide a world-class experience for every attendee. Whether it's the thrill of game day, the excitement of a live concert, or the camaraderie of community events, we pride ourselves on delivering a fan-first experience and maintaining operational excellence across all our activities. Our commitment to our fans and community is unwavering, and we continuously strive to enhance every aspect of their experience, ensuring they leave with unforgettable memories.
Slide 5:
Recent trends show an increasing demand for efficient event logistics. Our customer feedback has consistently highlighted frustrations with parking and traffic. Surveys indicate that a significant number of fans are dissatisfied with the current parking situation. Comparisons with other venues like Citizens Bank Park and Wells Fargo Center reveal that we lag in terms of parking efficiency and convenience. These insights underscore the urgent need for innovation to meet and exceed fan expectations.
Slide 6:
As we delve into the intricacies of our operations, one glaring issue emer
Netherlands vs Austria Netherlands Face Familiar Foes in Euro Cup Germany Gro...Eticketing.co
The Netherlands are in Group D in Euro Cup Germany - and, unpaid to this, they will be coming up against familiar foes. Remarkably, they have played France, who have fashioned some of the greatest players of all time, 30 times throughout history. Despite France being more effective in major competitions, including captivating the World Cup in 2018, Holland have the greater head-to-head record.

However, in 2023, they played one another twice, with France endearing both matches 4-0 and 2-1 individually. Against Poland and Austria, the Netherlands also have a stout record, winning just under half the matches. They faced Austria at Euro 2020, engaging 2-0, and they haven't lost to Poland since 1979.
The lettering is on the wall for Holland to qualify for the knockouts, but nothing is failsafe. The Netherlands kickstart their Euros campaign against Poland on Sunday, June 16th. In Hamburg, they will have to go up against one of the best strikers in the world, Robert Lewandowski.
Netherlands vs Austria: Tough Challenges Await the Netherlands in Euro Cup Germany
Five days later, they travel south to face France in Leipzig, a side led by Kylian Mbappe - one of the finest players in the world currently and one of the most impressive players in his nation's history. To conclude, they face Austria in Berlin, knowing it could be the end of the road if they don't perform.
Ronald Koeman is widely considered one of the more successful Dutch managers in Premier League history, considering the nation has a reputation for struggling to replicate their talents in England. The former Everton manager went against that script and shone — and now he is back managing his nation.

Netherlands vs Austria: Ronald Koeman's Tactical Approach For UEFA Euro 2024
As well as being the highest-scoring defender in history, Koeman is a man with immense tactical knowledge. He returned to manage Holland at the start of 2023 after it was announced Louis van Gaal would retire. His life back in the dugout with the team wasn't easy, as he lost his first match 4-0 to France after going 3-0 down within 21 minutes.
However, he eventually helped them qualify for Euro Cup Germany. The 61-year-old likes to organize his team with a defensive mindset. Some might call it pragmatic as he defends with minimal space between the lines, but that's often needed for international football.
