We determine optimal static prices for a finite capacity queueing system serving customers from different classes. We prove an upper bound for the optimal arrival rates for a fairly large class of queueing systems and provide sufficient conditions that ensure the existence of a unique optimal arrival rate vector. We show that these conditions hold for M/M/1/m and M/G/s/s systems and prove struc...

Airports all over the world are becoming busier and many of them are facing capacity problems. The actual airport capacity strongly depends on the efficiency of the resource utilisation. Although simultaneously handling all of the problems may result in more effective resource utilisation, historically different types of airport resources have been handled independently. Despite introducing new...

Large channel capacity is achieved by MIMO (Multiple-Input Multiple-Output) technology with multi-antenna at the transmitting and receiving side [1]. Many studies to maximize the MIMO channel capacity have been performed, and measurements show that channel capacity is enhanced by directional antennas [2] and multi-polarization [3] in indoor environment. Various MIMO antennas with pattern and po...

Empowerment is a recently introduced intrinsic motivation algorithm based on the embodiment of an agent and the dynamics of the world the agent is situated in. Computed as the channel capacity from an agent’s actuators to an agent’s sensors, it offers a quantitative measure of how much an agent is in control of the world it can perceive. In this paper, we expand the approximation of empowerment...

The conventional MIMO systems have a capability of enhancing channel capacity by exploiting multipath environment [1]. Recently, a novel scheme which utilizes MIMO system in near-field region has proposed [2]. In the near-field MIMO system, channel capacity is able to be improved without a multipath, because spherical wave is considered as a superposition of plane waves. It is expected that the...

A distributed binary hypothesis testing problem is studied with one observer and two decision centers. The type-II error exponents region is derived for testing against independence when the observer communicates with the two decision centers over one common and two individual noise-free bit pipes. When there is only a common noise-free bit pipe, the type-II error exponents region is derived fo...

In parallel with terrestrial and satellite wireless networks, a new alternative based on platforms located in the stratosphere has recently introduced, known as High Altitude Platforms (HAPS). HAPS are either airships or aircraft positioned between 17 and 22.5 km above the earth surface. It has capability to deliver a wide spectrum of applications to both mobile and fixed users over a broad cov...

We investigate the effects of fading correlations in multielement antenna (MEA) communication systems. Pioneering studies showed that if the fades connecting pairs of transmit and receive antenna elements are independently, identically distributed, MEA’s offer a large increase in capacity compared to single-antenna systems. An MEA system can be described in terms of spatial eigenmodes, which ar...

In this paper, we introduce the root of digital human binary coded Jong Nang communications as the wooden gate in Korea Jeju Island custom, has been using after about 1234 years. We compare the digital logic with modern traffic signal codes and analysis of both cases. Shannon channel capacity of the Jong Nang are 3 input NOR and binary erasure multiple access channel. Jong Nang communications i...

We examine a multiple-access communication system in which multiuser detection is performed without knowledge of the number of active interferers. Using a statistical-physics approach, we compute the single-user channel capacity and spectral efficiency in the large-system limit.
