How to Split UL/DL Antennas in Full-Duplex Cellular Networks

To further improve the potential of full-duplex communications, networks may employ multiple antennas at the base station or user equipment. To this end, networks that employ current radios usually deal with self-interference and multi-user interference by beamforming techniques. Although previous works investigated beamforming design to improve spectral efficiency, the fundamental question of how to split the antennas at a base station between uplink and downlink in full-duplex networks has not been investigated rigorously. This paper addresses this question by posing antenna splitting as a binary nonlinear optimization problem to minimize the sum mean squared error of the received data symbols. It is shown that this is an NP-hard problem. This combinatorial problem is dealt with by equivalent formulations, iterative convex approximations, and a binary relaxation. The proposed algorithm is guaranteed to converge to a stationary solution of the relaxed problem with much smaller complexity than exhaustive search. Numerical results indicate that the proposed solution is close to the optimal in both high and low self-interference capable scenarios, while the usually assumed antenna splitting is far from optimal. For large number of antennas, a simple antenna splitting is close to the proposed solution. This reveals that the importance of antenna splitting is inversely proportional with the number of antennas.Comment: 7 pages, 4 figures.

Development of Shoe Dryer system using Microcontroller with GSM Module

This paper describes the design and development of a shoe dryer using a microcontroller. Nowadays, people often travel and sometimes in rainy day, they need to dry their shoe in a very short time anywhere. However, very rare of places including shopping mall and hotel provide a shoe dryer. The shoe dryer is designed to help people who are in hurry to dry their shoe on the go. A temperature sensor is used to measure the temperature inside the shoe dryer, while a program is uploaded in the microcontroller for reading and data collection. The programming includes the activation of shoe dryer with the GSM module, thus it can be controlled using a mobile phone. An experiment was conducted to test the performance of the shoe dryer. The optimum performance was obtained when the temperature is set at 36°C, and timer at 60 seconds with normal room temperature. The temperature and timer need to be adjusted accordingly based on the shoe condition in order to get very satisfying results. This paper proved that the shoe dryer was successfully designed, implemented and analyzed

Weekly variations of accelerometer variables and workload of professional soccer players from different positions throughout a season

The current study aimed to analyze, using accelerometer-based activity, acute workload, chronic workload, acutechronic workloads ratio, training-monotony and training-strain throughout a competitive soccer-season and to compare these variables between players from different playing positions. Twenty-one professional soccer-players were monitored during the 48 weeks of the season. Players were grouped according to their position. Four lateral-defenders and four winger-players formed LDW group, four central-defenders and four forwards formed CDF group, and six midfielder-players formed MDF group. Accelerometer-based variables were collected during training and match contexts and were used to generate indicators of weekly acute and chronic workload, training monotony, training strain and metabolic power. A one-way ANOVA compared all dependent variables between groups, and effect sizes for pairwise comparisons were calculated. Results revealed variations in the weekly load throughout the season, which demands caution from coaches to avoid injuries. There were no differences in weekly-loads for all dependent variables (P > 0.05, small-to-moderate effects). We conclude that the weekly-load is not constant during a competitive season and players from different positions have similar weekly-loads. Therefore, previously reported in the literature, possible match-related positional differences might be compensated by differences in training-related loads, leading to a similar profile when considering the whole week

“We’re still here”:Misrecognition and the quest for dual identification of Roma people

Misrecognition describes everyday practices that deny the autonomy of minority members to define who they are and instead impose identities that may diverge from their own sense of self. Being misrecognized is particularly relevant for the historically marginalized Roma people, whose national belonging is repeatedly questioned despite centuries of co-existence and citizenship. Our aim was to understand whether the experience of misrecognition, along with discrimination, would predict identification patterns that represent an obstacle to dual identification among Roma people in three East-Central European countries: Hungary, Romania and Serbia. We collected data among Roma participants online and face-to-face with convenience sampling (N = 1,325). Latent class analysis revealed three similar classes based on national and ethnic identification scores in all subsamples: (1) disidentification, (2) Roma identification and (3) dual identification. Logistic regression analysis showed that misrecognition and discrimination predicted stronger Roma identity than dual identification in Hungary and Serbia. However, misrecognition predicted stronger dual identification in Romania, possibly as a reaffirmation strategy in response to misrecognition. Our results show that misrecognition can add to our understanding of minority group members' identification with the superordinate category of the nation as well as subgroup ethnic minority identity, and this connection could be key for advancing Roma inclusion

Uma revisão sobre os principais aspectos no cultivo do robalo

Marine fish breeding is an activity that presents great growth trend, in which one of the groups of fish with high commercial interest are the snooks of the genus Centropomus. Two species of this genus show favorable characteristics for captive breeding, the fat snook, C. parallelus, and common snook, C. undecimalis. This review has the objective of approaching the main aspects of snook breeding and their future prospects for the expansion of this activity. The technology for snook breeding is more advanced when compared to other marine species, however there are still some bottlenecks and further studies are necessary to obtain better performance levels in captivity, particularly during the fattening phase. The fat snook is the species with greater economic interest because it shows good adaptation to captive breeding and has more advanced breeding technology. Regarding the common snook, its reproduction has yet to be dominated.A piscicultura marinha é uma atividade que apresenta grande tendência de crescimento, sendo que um dos grupos de peixes com grande interesse comercial são os robalos, pertencentes ao gênero Centropomus. Duas espécies desse gênero apresentam características favoráveis para produção em cativeiro, o robalo-peva, C. parallelus, e o robalo-flecha, C. undecimalis. Esta revisão tem como objetivo abordar os principais aspectos sobre o cultivo de robalos e suas perspectivas futuras para ampliação da atividade. A tecnologia de criação dos robalos está mais avançada em relação a outras espécies marinhas, entretanto ainda existem alguns gargalos e são necessários mais estudos para a obtenção de melhores índices de desempenho em cativeiro, principalmente durante a fase de engorda. O robalo-peva é a espécie com maior interesse econômico, por apresentar uma boa adaptação ao cultivo em cativeiro e possuir tecnologia de cultivo mais avançada. No caso robalo-flecha a reprodução ainda precisa ser dominada

The star formation history of mass-selected galaxies from the VIDEO survey

© 2014 The Authors Published by Oxford University Press on behalf of the Royal Astronomical SocietyWe measure star formation rates (SFRs) and specific SFRs (SSFRs) of Ks-selected galaxies from the VISTA Deep Extragalactic Observations survey by stacking 1.4 GHz Very Large Array data.We split the sample, which spans 0 < z<3 and stellar masses 108.0 < M*/M⊙ < 1011.5, into elliptical, irregular or starburst galaxies based on their spectral energy distributions. We find that SSFR falls with stellar mass, in agreement with the 'downsizing' paradigm. We consider the dependence of the SSFR-mass slope on redshift: for our full and elliptical samples the slope flattens, but for the irregular and starburst samples the slope is independent of redshift. The rate of SSFR evolution reduces slightly with stellar mass for ellipticals, but irregulars and starbursts co-evolve across stellar masses. Our results for SSFR as a function of stellar mass and redshift are in agreement with those derived from other radio-stacking measurements of mass-selected passive and star-forming galaxies, but inconsistent with those generated from semi-analytic models, which tend to underestimate SFRs and SSFRs. There is a need for deeper high-resolution radio surveys such as those from telescopes like the next-generation MeerKAT in order to probe lower masses at earlier times and to permit direct detections, i.e. to study individual galaxies in detail.Peer reviewe

Gravitational collapse with tachyon field and barotropic fluid

A particular class of space-time, with a tachyon field, \phi, and a barotropic fluid constituting the matter content, is considered herein as a model for gravitational collapse. For simplicity, the tachyon potential is assumed to be of inverse square form i.e., V(\phi) \sim \phi^{-2}. Our purpose, by making use of the specific kinematical features of the tachyon, which are rather different from a standard scalar field, is to establish the several types of asymptotic behavior that our matter content induces. Employing a dynamical system analysis, complemented by a thorough numerical study, we find classical solutions corresponding to a naked singularity or a black hole formation. In particular, there is a subset where the fluid and tachyon participate in an interesting tracking behaviour, depending sensitively on the initial conditions for the energy densities of the tachyon field and barotropic fluid. Two other classes of solutions are present, corresponding respectively, to either a tachyon or a barotropic fluid regime. Which of these emerges as dominant, will depend on the choice of the barotropic parameter, \gamma. Furthermore, these collapsing scenarios both have as final state the formation of a black hole.Comment: 18 pages, 7 figures. v3: minor changes. Final version to appear in GR
