We consider a multi-input multi-output (MIMO) block-fading channel with a general model for channel state information at the transmitter (CSIT). The model covers systems with causal CSIT, where only CSIT of past fading blocks is available, and predictive CSIT, where CSIT of some future fading blocks is available. The optimal diversity-multiplexing tradeoff (DMT) and ratediversity tradeoff (RDT)...

Auto-repeat is the automatic repetition of a function by continuous pressing of a button. In three separate tests, the design and operation of this auto-repeat feature for various electronical devices was examined. Eleven subjects took part in the experiment. Each subject was given the same stratgies for optimizing the auto-repeat feature. Both performance variables (ie. task completion time, n...

JUMP-1 is currently under development by seven Japanese universities to establish techniques of an e cient distributed shared memory on a massively parallel processor. It provides a memory coherency control scheme called the hierarchical bit-map directory to achieve cost e ective and high performance management of the cache memory. Messages for maintaining cache coherency are transferred throug...

In order to simulate or control the coupled heave–pitch motion of ships in waves as realistically possible, an appropriate mathematical model must be established advance. this paper, a nonparametric identification method, based on combination random decrement technique (RDT) and support vector regression (SVR), was proposed by only using measured responses at sea. First, describe irregular wave...

inner ear cells are sensitive to some metabolic and hormonal disorders, but the relation between chronic renal failure (crf), regular dialysis treatment (rdt) and sensorineural hearing loss (snhl) is still a debatable field. the object of this paper was to verify the presence of snhl in patients submitted to hemodialysis with different duration due to crf and in those submitted to conservative ...

The tidal turbines represent a new frontier for extracting energy from tides source. Despite the technology being mature, solutions aimed at improving performance, reliability with reduced environmental impact, manufacturing and installation costs are currently under investigation. Rim-driven turbine (abbreviated as RDT) was recently proposed. A RDT resembles ducted DT), both contain blades duc...

OBJECTIVE We sought to measure the residual dentin thickness (RDT) in the mesial roots of mandibular molars after instrumentation with Lightspeed and Gates-Glidden rotary instruments. Study design Thirty extracted, untreated human mesial roots of mandibular molars were separated from the distal roots and embedded in clear polyester resin. The roots were cut horizontally at 1, 4, and 7 mm short ...

BACKGROUND Rapid diagnostic tests (RDTs) have been commercialized in order to help physicians in dengue diagnosis. Until recently, only blood samples were used for those tests but it has been shown in several studies that urine and saliva can also be employed for dengue diagnosis. RDTs for the detection of NS1 antigen and anti-dengue IgG, IgM and IgA in urine and saliva specimens have thus been...

AIMS The main focus of this study is to illustrate the importance of the statistical analysis in the evaluation of the accuracy of malaria diagnostic tests, without admitting a reference test, exploring a dataset (n=3317) collected in São Tomé and Príncipe. METHODS Bayesian Latent Class Models (without and with constraints) are used to estimate the malaria infection prevalence, together with ...

BACKGROUND & OBJECTIVES Rapid diagnostic test (RDT) kits are widely used in India for the diagnosis of dengue infection. It is important to evaluate the validity and reliability of these RDTs. The study was aimed to determine the sensitivity, specificity and predictive value of four commercially available RDTs [Panbio Dengue Duo cassette, Standard Diagnostics (SD) Bioline Dengue Duo, J. Mitra D...
