Polarization-adjusted convolutional (PAC) codes have better error-correcting performance than polar mostly because of the improved weight distribution brought by pre-transformation. In this paper, we propose parity check PAC (PC-PAC) to further improve codes. The design principle is establish functions between bits with distinct row weights, such that information lower reliability are re-protec...

background: water, sanitation and hygiene have a very important role in public health. poor sanitation is the cause of water contamination, which causes many types of diseases. the aim of this paper was to present the attributable death and disability adjusted life year (dalys) of untreated water and insanitary environments from 1990 to 2010 in iran.   methods: in the global burden of disease 2...

objectives : to estimate the disabled-adjusted life years ( dalys) of road traffic accidents in patients referred to hospitals in yazd province, central iran. methods: this cross-sectional study was conducted in yazd province during 2010. to calculate the years of life lost (yll) due to premature death and to calculate the incidence of non-fatal injuries and years lost due to disability (yld), ...

Control charts are widely used in industrial processes as well as in health sciences and particularly for monitoring the performance of cardiac surgeon or a group of surgeons based on the preoperative risk of patients. Since the preoperative risk is a vague and nonprecise variable and the anesthesiologists after checking how many risk factors a patient has, determine the risk of mortality befor...

Inspired by the recent results in [4] and the concept of metric adjusted skew information introduced by Hansen in [6], we here give a further generalization for Schrödinger-type uncertainty relation applying metric adjusted correlation measure introduced in [6]. We firstly give some notations according to those in [4]. Let Mn(C) and Mn,sa(C) be the set of all n × n complex matrices and all n × ...

OBJECTIVES The following study analyses the influence of risk factors among the occupational group of truck drivers on postural control and body mass index (BMI). DESIGN Observational study. SETTING One motorway station close to several highways in Germany. PARTICIPANTS 180 truck drivers (177 male/3 female), aged 21-65 years old, took part in this study. OUTCOME MEASURES Postural contro...

We consider coupling conditions for the “Aw–Rascle” (AR) traffic flow model at an arbitrary road intersection. In contrast with coupling conditions previously introduced in [10] and [7], all the moments of the AR system are conserved and the total flux at the junction is maximized. This nonlinear optimization problem is solved completely. We show how the two simple cases of merging and divergin...

Firstly, this paper researches on the scheme of amplitude weighting(AW) for smart antenna(SA) beamforming in linear array. With the proposed mathematical model in this paper, QPSK base-band AW is an effective method for linear SA to realize multi-user and multi-direction transmission, by which the perfect directional beam-forming can be realized with low complexity and low cost. Secondly, this ...
