Die Tumeszenz-Lokalanasthesie (TLA) spielt bei dermatochirurgischen Eingriffen eine wichtige Rolle. TLA bietet etliche Vorteile, wie lang anhaltende Betaubung, reduzierte Blutung wahrend der Operation und Vermeidung moglicher Komplikationen einer Vollnarkose. Einfache Durchfuhrung, gunstiges Risikoprofil breites Indikationsspektrum sind weitere Grunde dafur, dass zunehmend auch Sauglingen einge...

A distributed hash table (DHT) is a peer-to-peer network that o↵ers the function of a classic hash table, but where di↵erent key-value pairs are stored at di↵erent nodes on the network. Like a classic hash table, the main function provided by a DHT is key lookup, which retrieves the value stored at a given key. Examples of DHT protocols include Chord, Pastry, Kademlia and Tapestry. Such DHT pro...

The main goal of this project was to learn the TLA+ specification language and to start exploring the practical limitations of modeling and simulating unreliable systems. A TLA+ specification for a naive asynchronous consensus protocol is presented along with the model-checking times for one to eight processes under crash-free conditions. Model-Checking times increase drastically with added pro...

This paper focuses on examining research into teaching, learning and assessment (TLA) in higher education in terms of structure and agency. It argues that although issues of structure and agency are seen as crucial in social theory, they are very little discussed in research into TLA in higher education and that a consideration of structure and agency raises some important questions about this ...

Executions in the PharOS real-time system are deterministic in the sense that the sequence of local states for every process is independent of the order in which processes are scheduled. The essential ingredient for achieving this property is that a temporal window of execution is associated with every instruction. Messages become visible to receiving processes only after the time window of the...

We investigate the use of a TLA speciication for modeling and proving parallelization within an object-oriented language. Our model is based on Eiiel== a parallel extension of Eiiel, where sequential programs can be reused for parallel or concurrent programming with very minor changes. We want to prove that both versions of a given program (sequential and parallel) are equivalent with respect t...

Alloy and TLA are two formal specification languages that are increasingly popular due to their simplicity and flexibility, as well as the effectiveness of their companion model checkers, the Alloy Analyzer and TLC, respectively. Nonetheless, while TLA focuses on temporal properties, Alloy is better suited to handle structural properties, requiring ad hoc mechanisms to reason about temporal pro...

In mobile environments, a personal communication service (PCS) network must keep track of the location of each mobile user in order to correctly deliver calls. A basic scheme used in the standard IS-41 and GSM protocols is to always update the location of a mobile user whenever the mobile user moves to a new location. The problem with this approach is that the cost of location update operations...
