In DSL, systems are composed of several sites executed asynchronously, and each site is running scripts in a synchronous parallel way. Scripts may call functions that are considered in an abstract way: their effect on the memory is not considered, but only their "orchestration" i.e. the organisation of their calls in time and in place (the site where they are called). The mapping of sites onto cores allows one to benefit from multicore architectures. Two properties are assumed by DSL: reactivity of sites and absence of interferences between scripts run by distinct sites. We consider several variants of DSL. In the first variant, functions are defined in FunLoft. In the second variant of DSL, functions are defined in ReactiveML and the JoCaml system is used for asynchronous inter-sites communications. The third variant is based on SugarCubes which is a Java based framework for reactive programming. Finally, in the fourth variant, functions are defined in Scheme/Bigloo. * with support from ANR-08-EMER-010, project PARTOUT * ref thread_t | _Par of instruction_t * instruction_t * ref thread_t * ref thread_t | _Loop of instruction_t * ref thread_t | _Repeat of int_wrapper_t * instruction_t * ref thread_t | _Generate of string | _Await of string | _Watching of string * instruction_t * ref thread_t * ref thread_t | _Drop of ref site_t * instruction_t and site_t = Site of rengine: ref engine_t * sched: scheduler_t and engine_t = Engine of eoi: (unit) event_t * pre_eoi: (unit) event_t * move: ref bool * instant: ref int * sustain: ref[array_size] (unit) event_t * sustain_count:ref int * add: (instruction_t) event_t * event_env: ((unit) event_t) aa_t * wakeup: (unit) event_t * next: ref bool

The objective of this program is twofold. Firstly, to allow them to train their fine motor skills on tablet. Secondly, to study the effect of this training on their numerical performance (counting, calculation...). The target population and the objective of evaluating numerical skills influenced the design. The software was developed using standard web technologies but is based on a new parallel programming library written in JavaScript. Applications and libraries are free of charge and easy to install on most tablets.

The SugarCubes can be seen as a low-level basis upon which more complex reactive formalisms can be implemented. They also provide a convenient framework for prototyping experimental extensions to various reactive formalisms. The

L'approche réactive de JAVA : sémantique et implémentation des SUGARCUBES et de JUNIOR

L'Approche Reactive definie par F. Boussinot en 1991 avec Reactive-C propose un ensemble de formalismes permettant de decrire simplement des systemes reactifs pouvant etre enrichis dynamiquement en cours d'execution. L'Approche Reactive qui derive de l'Approche Synchrone repose sur une decoupe logique de l'execution d'un programme en une succession d'instants. La notion d'instant permet de definir un parallelisme synchrone et un puissant mecanisme de communication entre composants paralleles : la diffusion instantanee d'evenements. La these decrit un ensemble de travaux implementant l'Approche Reactive en Java. Deux formalismes SugarCubes et Junior sont decrits en details. Ils permettent de construire sur une base formelle des s...

SugarCubes is a set of Java classes used to implement reactive, event based, concurrent systems. ... more SugarCubes is a set of Java classes used to implement reactive, event based, concurrent systems. It is a low-level basis upon which more complex reactive formalisms can be implemented. SugarCubes introduces the notion of a global logical instant of execution, which is used to define synchronous parallelism and concurrency. It is also used to define instantaneous broadcasting of events which is a powerful communication mechanism. The second release of the SugarCubes package introduces some new extensions for easy implemention of dynamic and modular systems. It also defines a more accurate interface between reactive programs and standard Java objects. Basically, it introduces the notion of a reactive object, called cube, and focus on descriptions and combinations of behaviors of such objects. SugarCubes is freely available on the Web.

The choice of RP is motivated by the fact that RP genuinely offers logical parallelism, instantaneously broadcast events, and dynamic creation/destruction of parallel components and events. To illustrate our approach, we consider the implementation of a system of Molecular Dynamics, in the context of Java with the Java3D library for 3D visualization.

This reactive approach is based on an instantaneously broadcast event model and a semanticallysound synchronous/reactive formalism. The reactive framework degree of expressiveness is illustrated through several examples of behaviors which range from low-level animation of virtual creatures to high-level control of autonomous creatures' actions.

Instead of targeting IP stacks implementation in tags, we plan to support the Host Identity Protocol, which dissociates IP address and host location and that has been recently defined by the Internet Engineering Task Force (IETF). We propose an architecture, in which a

We propose an infrastructure that works with a new type of tags, supporting the recently standardized Host Identity Protocol (HIP). Our main concern is to ensure RFID tags privacy, while enabling things to things communications.
