JPG, PNG and BMP image compression using discrete cosine transform
This paper proposes image compression using discrete cosine transform
(DCT) for the format of joint photographic expert groups (JPEG) or JPG,
portable network graphic (PNG) and bitmap (BMP). These three extensions
are the most popular types used…

Hemogram-derived ratios as prognostic markers of ICU admission in COVID-19
Background: The vast impact of COVID-19 call for the identification of clinical parameter that can help predict a
torpid evolution. Among these, endothelial injury has been proposed as one of the main pathophysiological
mechanisms underlying the…

Incidence of in-hospital cardiac arrest at general wards before and after implementation of an early warning score
Background: In order to reduce the incidence of in-hospital cardiac arrest (IHCA) at general wards, medical
emergency teams (MET) were implemented in the Capital Region of Denmark in 2012 as the efferent part of a track
and trigger system. The…

Distribution power loss minimization via optimal sizing and placement of shunt capacitor and distributed generator with network reconfiguration
The population is speeding up and the demands for electrical energy are clearly
increasing, this growth in load leads to higher power loss and Voltage drop.
This paper is focused on a method to decrease the power losses and voltage
profile…

Time series analysis of electric energy consumption using autoregressive integrated moving average model and Holt Winters model
With the increasing demand of energy, the energy production is not that much
sufficient and that’s why it has become an important issue to make accurate
prediction of energy consumption for efficient management of energy. Hence
appropriate demand…

Enhancement of luminous flux and color quality of white
light-emitting diodes by using green (Y,Gd)BO3:Tb3+ phosphor
In the study, we analyzed and clarified the effect of green (Y,Gd)BO3:Tb3+
phosphor on chromatic homogeneity and optical performance of multi-chip
white light emitting diodes (MCW-LEDs). Thereby there is a solution to get
the best luminous…

The impacts of red-emitting phosphor Mg8Ge2O11F2:Mn4+ on the color rendering index of convex-dual-layer remote phosphor WLEDs at 5600 K
The poor color rendering index (CRI) induced by mono chip and phosphor
configuration in the conventional white-light light-emitting diode (LED)
urges for developments in both packaging and material, thus, a modern
lighting solution was introduced.…

Predicting mortality among septic patients presenting to the emergency department– a cross sectional analysis using machine learning
Background: Sepsis is a life-threatening condition, causing almost one fifth of all deaths worldwide. The aim of the
current study was to identify variables predictive of 7- and 30-day mortality among variables reflective of the
presentation of…
