We take a game theory approach to study the make-or-buy decisions of firms in a mixed duopoly. We assume that a managerial firm and a profit-oriented firm compete in a duopoly market for a final good, and they can choose whether making an intermediate input or buying it from a monopolistic upstream firm. We find that different equilibria may arise, depending on parameter constellations. In part...

Traditional Turbo EQualization (TEQ) schemes suffer from residual bit errors due to the non-recursive nature of the channel imposing Inter-Symbol-Interference (ISI). The performance of the traditional TEQ scheme may, however, be improved if an intermediate recursive channel codec is invoked, which results in a three-stage serially concatenated system. This intermediate code is necessary, especi...

Transport models are the main method to obtain physics information on nuclear equation of state and in-medium properties particles from low relativistic-energy heavy-ion collisions. The Model Evaluation Project (TMEP) has been pursued test robustness transport model predictions in reaching consistent conclusions same type physical model. To this end, calculations under controlled conditions inp...

This paper presents a new fast way to simulate large networks of computers. The method uses a frontend EC, which accepts a parallel C program and translates it into a program in an intermediate language for parallel system simulations. An event driven simulator for distributed shared memory systems, DSIM, uses the intermediate language to simulate and obtain ee-ciency results in networks of tho...

Taking advantage of a historical quasi-experiment in Sri Lanka, this paper provides evidence on the effects of land market restrictions on equilibrium wage and its spatial pattern. For identification, we exploit the effects of historical malaria prevalence on the incidence of land restrictions through the availability of ‘crown land’. The results show that there is important spatial heterogenei...

We designed an optical-digital system that delivers near-diffraction-limited imaging performance with a large depth of field. This system is the standard incoherent optical system modified by a phase mask with digital processing of the resulting intermediate image. The phase mask alters or codes the received incoherent wave front in such a way that the point-spread function and the optical tran...

introduction: standard codes and their descriptions are important tools for research, design, implementation and evaluation of the injury control program and its sub-categories. methods: in this research the medical records of 735 patients diagnosed with injuries, burns or poisonings from teaching-hospitals of the iran, tehran and shahid beheshti medical universities (n=22) were selected to be ...

We give two methods for constructing many linear complementary dual (LCD short) codes from a given LCD code, by modifying some known self-dual codes. Using the methods, we construct binary and quaternary Hermitian codes, which improve previously lower bounds on largest minimum weights.

Fountain codes are widely employed to improve reliability and efficiency in wireless communication systems due their simple coding mechanisms. In this letter, we propose an opportunistic decoding recoding mechanism with coordinative routing algorithm for fountain the expected transmission counts (ETX) performance reduce computational complexity of at each relay multi-hop sensor networks. The fu...
