Active Target Defense Differential Game with a Fast Defender
This paper addresses the active target defense differential game where an
Attacker missile pursues a Target aircraft. A Defender missile is fired by the
Target's wingman in order to intercept the Attacker before it reaches the
aircraft. Thus, a team is formed by the Target and the Defender which cooperate
to maximize the distance between the Target aircraft and the point where the
Attacker missile is intercepted by the Defender missile, while the Attacker
tries to minimize said distance. The results shown here extend previous work.
We consider here the case where the Defender is faster than the Attacker. The
solution to this differential game provides optimal heading angles for the
Target and the Defender team to maximize the terminal separation between Target
and Attacker and it also provides the optimal heading angle for the Attacker to
minimize the said distance.Comment: 9 pages, 8 figures. A shorter version of this paper will be presented

Escape Regions of the Active Target Defense Differential Game
The active target defense differential game is addressed in this paper. In
this differential game an Attacker missile pursues a Target aircraft. The
aircraft is however aided by a Defender missile launched by, say, the wingman,
to intercept the Attacker before it reaches the Target aircraft. Thus, a team
is formed by the Target and the Defender which cooperate to maximize the
separation between the Target aircraft and the point where the Attacker missile
is intercepted by the Defender missile, while the Attacker simultaneously tries
to minimize said distance. This paper focuses on characterizing the set of
coordinates such that if the Target's initial position belong to this set then
its survival is guaranteed if both the Target and the Defender follow their
optimal strategies. Such optimal strategies are presented in this paper as
well.Comment: 19 pages, 9 figures. arXiv admin note: text overlap with

Decentralized Event-Triggered Consensus of Linear Multi-agent Systems under Directed Graphs
An event-triggered control technique for consensus of multi-agent systems
with general linear dynamics is presented. This paper extends previous work to
consider agents that are connected using directed graphs. Additionally, the
approach shown here provides asymptotic consensus with guaranteed positive
inter-event time intervals. This event-triggered control method is also used in
the case where communication delays are present. For the communication delay
case we also show that the agents achieve consensus asymptotically and that,
for every agent, the time intervals between consecutive transmissions is
lower-bounded by a positive constant.Comment: 9 pages, 5 figures, A preliminary version of this manuscript has been

La subjetividad como factor determinante en el sentido de una sentencia penal
El objetivo es analizar la forma en que una sentencia es emitida por los agentes intrínsecos del resolutor, lo que determina de manera definitiva el sentido de la misma. Aunque resulta innegable que existen mecanismos objetivos en la determinación de la sentencia, es imperante revisar cómo algunos elementos subjetivos inherentes al resolutor pueden contribuir también a dicha resolución. En este sentido, con base en antecedentes investigativos nacionales e internacionales, la obra postula que factores como la edad, el género, estados de ánimo y experiencias personales, entre otros, tornan la decisión judicial parcialmente subjetiva
