Content created by users is a public affair. In the cultural field of music, this includes diverse activities of listening, sharing, editing, recording. Jacques Attali predicts that music will become a network of composition, where people actively participate in music-as-process, as a form of collective play [Attali, 1985]. Christopher Small coined the term, musicking, to describe music as a so...

Nowadays, music fans are beginning to massively use mobile digital music players and dedicated software to organize and play large collections of music. In this context, users deal with huge music libraries containing thousands of tracks. Such a huge volume of music easily overwhelms users when selecting the music to listen or when organizing their collections. Music player software with visual...

Multicasting in deflection networks is more difficult than in store-and-forward networks, because of the difficulties in sending multiple copies of the same packet on several output ports. On the other hand, deflected packets stray from their optimal paths and may visit the multicast recipients “accidentally,” not necessary in the order envisioned by the sender. We compare a number of simple mu...

In aviation, using external stores under the wings is a common method of carrying payload or fuel. some cases, can be rigidly attached to wing. However, must often ejected during flight for aircraft, such as military type, which carry drop tanks and missiles. This may cause wing respond dynamically with increasing amplitudes, due impulsive load ejection change total mass. especially critical in...

The objective of this project is to forecast sales in euros at 1115 stores owned by Rossmann, a European pharmaceutical company. The input to our algorithm is a feature vector (discussed in section 3) of a single day of data for that store. We tried using a number of algorithms, but mainly gradient boosting, to output the predicted total sales in euros for the given store that day. Rossmann pro...

An Augmented Knight’s Castle (AKC) play set was adapted so that children with autism can configure programmable elements. This is compared with a non-configurable AKC. When the system is configurable, and when it is switched on, less solitary play and more cooperative play occur. Digital toys and their configurability are key factors in design for children with autism, allowing greater individu...

Users are increasingly inundated with small devices with communication and storage capabilities. Unfortunately, the user is still responsible for reconciling all of the devices whenever a change is made. We present Footloose, a usercentered data store that can share data and reconcile conflicts across diverse devices. Footloose is an optimistic system based on physical eventual consistency—cons...
