1. The document presents a logistic regression model to analyze the probability of individuals switching from private transportation to public transportation based on parking rates.
2. A logistic function is fitted to the data and parameters α and C are estimated. The model shows a high goodness of fit (R2 = 0.9834).
3. The methodology is then applied to analyze switching from private to public transportation based on bus fare discounts and reduced travel time. A multiple logistic regression model is developed relating probability of switching to fare and time.

Cloud PARTE: Elastic Complex Event Processing based on Mobile ActorsStefan Marr
Traffic monitoring or crowd management systems produce large amounts of data in the form of events that need to be processed to detect relevant incidents.
Rule-based pattern recognition is a promising approach for these applications, however, increasing amounts of data as well as large and complex rule sets demand for more and more processing power and memory. In order to scale such applications, a rule-based pattern detection system needs to be distributable over multiple machines. Today’s approaches are however focused on static distribution of rules or do not support reasoning over the full set of events.
We propose Cloud PARTE, a complex event detection system that implements the Rete algorithm on top of mobile actors. These actors can migrate between machines to respond to changes in the work load distribution. Cloud PARTE is an extension of PARTE and offers the first rule engine specifically tailored for continuous complex event detection that is able to benefit from elastic systems as provided by cloud computing platforms. It supports fully automatic load balancing and supports online rules with access to the entire event pool.
Shortest Path search for real road networks with pgRoutingDaniel Kastl
pgRouting adds routing functionality to PostGIS. This presentation will show the inside and current state of pgRouting development. We will explain the shortest path search in real road networks and how the data structure is important to get better routing results. Furthermore we will show how you can improve the quality of the search with dynamic costs and make the result look closer to the reality. You will learn about difficulties and limitations of implementing routing functionality in GIS applications, the difference between algorithms and their performance.
pgRouting includes:
- Shortest path search (3 algorithms: Dijkstra, A-Star, Shooting Star)
- Traveling salesperson problem solver (TSP)
- Driving distance calculation
- NEW: Dial-a-ride-problem solver (DARP)
- NEW: All-pair-shortest-path algorithm (APSP)
pgRouting is an extension of PostgreSQL and PostGIS. A predecessor of pgRouting's pgDijkstra, written by Camptocamp, was later extended by Orkney and renamed to pgRouting. The project is now supported by Georepublic and a broad user community.
James Burkhart explains how Uber supports millions of analytical queries daily across real-time data with Apollo. James covers the architectural decisions and lessons learned building an exactly-once ingest pipeline storing raw events across in-memory row storage and on-disk columnar storage and a custom metalanguage and query layer leveraging partial OLAP result set caching and query canonicalization. Putting all the pieces together provides thousands of Uber employees with subsecond p95 latency analytical queries spanning hundreds of millions of recent events.
This presentation, created by Syed Faiz ul Hassan, explores the profound influence of media on public perception and behavior. It delves into the evolution of media from oral traditions to modern digital and social media platforms. Key topics include the role of media in information propagation, socialization, crisis awareness, globalization, and education. The presentation also examines media influence through agenda setting, propaganda, and manipulative techniques used by advertisers and marketers. Furthermore, it highlights the impact of surveillance enabled by media technologies on personal behavior and preferences. Through this comprehensive overview, the presentation aims to shed light on how media shapes collective consciousness and public opinion.

0x01 - Newton's Third Law: Static vs. Dynamic AbusersOWASP Beja
f you offer a service on the web, odds are that someone will abuse it. Be it an API, a SaaS, a PaaS, or even a static website, someone somewhere will try to figure out a way to use it to their own needs. In this talk we'll compare measures that are effective against static attackers and how to battle a dynamic attacker who adapts to your counter-measures.
