Among the goals of 3GPP LTE networks are higher user bit rates, lower delays, increased spectrum efficiency, support for diverse QoS requirements, reduced cost, and operational simplicity. Resource scheduling and interference mitigation are two functions which are key to achieving these goals. This paper provides a survey of related techniques which have been proposed and shown to be promising....

This paper considers the problem of achieving attitude consensus in spacecraft formations with bounded, time-varying communication delays between spacecraft connected as specified by a strongly connected topology. A state feedback controller is proposed and investigated using a time domain approach (via LMIs) and a frequency domain approach (via the small-gain theorem) to obtain delay dependent...

Cheung et al1 stated that only 41% of their patients underwent PPCI within the American College of Cardiology/American Heart Association– recommended door-to-balloon time (DTBT) of 90 minutes, and there were further delays out-of-hours. The authors concluded that achieving these targets was “very difficult in real-life environments”, and a 24-hour cardiology service was “difficult to achieve lo...

We consider a pair of mutually coupled inhibitory neurons in which each neuron is also self-inhibitory. We show that the size of the synaptic delay determines the existence and stability of solutions. For small delays, there is no synchronous solution, but a stable antiphase and a stable on-state solution. For long delays, only the synchronous solution is stable. For intermediate delays, either...

This paper examines the effects of delays in Algerian construction industry order to identify various critical aspects causes for improving economy sector. A questionnaire survey was conducted assess perceptions all players industry, which led identification most significant impacts delays. The results show that ten main sector are at origin many constraints have a negative impact on country. F...
