We consider the performance of a network like the In-ternet handling so-called elastic traac where the rate of ows adjusts to ll available bandwidth. Realized throughput depends both on the way bandwidth is shared and on the random nature of traac. We assume traac consists of point to point transfers of individual documents of nite size arriving according to a Poisson process. Notable results a...

In this paper we systematically study several channel assignment problems in multi-hop ad-hoc wireless networks in the presence of several constraints. Both regular grids and random topology models are considered in the analysis. We identify three fairness constraints (unfair, fair, and 1-fair), Signal to Interference Ratio (SINR) constraint (to measure the link quality) and balance constraint ...

A number of emerging Internet applications such as videoconferencing and live multimedia broadcasts from Internet TV stations will rely on scheduling algorithms in switches and routers to guarantee performance and an acceptable level of quality of service. Fairness in packet schedulers is an intuitively desirable property with practical value; fair schedulers such as Weighted Fair Queueing are ...

We examine the causes and consequences of European real estate firms’ decisions to provide investment property fair values prior to the required disclosure of this information under International Financial Reporting Standards (IFRS). We find evidence that investor demand for fair value information—reflected in more dispersed ownership—and a firm’s commitment to transparency increase the likelih...

Quantum measurement is a basic tool to manifest intrinsic quantum effects from fundamental tests information applications. While typically performed gain on state, its role in technology indeed manifold. For instance, crucial process element measurement-based computation. It also used detect and correct errors thereby protecting error-correcting frameworks. therefore important fully characteriz...

Why did the nation-state proliferate across the world over the past 200 years, replacing empires, kingdoms, city-states, and the like? Using a new dataset with information on 145 of today’s states from 1816 to the year they achieved nation-statehood, we test key aspects of modernization, world polity, and historical institutionalist theories. Event history analysis shows that a nation-state is ...

In a search task, a group of agents compete to be the first to find the solution. Each agent has different private information to incorporate into its search. This problem is inspired by settings such as scientific research, Bitcoin hash inversion, or hunting for some buried treasure. A social planner such as a funding agency, mining pool, or pirate captain might like to convince the agents to ...

Motor skills are always considered as one of the effective factors on human activities. The purpose of this research is to study the role of birth order and birth weight in the static and dynamic balance of boys aged 9-11 years old. 94 male students have been evaluated in this research. The personal information questionnaire and medical records were used to acquire data pertaining to birth or...
