Traffic flow measurement for smart traffic light system design
Determining congestions on intersection roads can significantly improve the
performance of a traffic light system. One of the everyday problems on our
roads nowadays is the unbalanced traffic on different roads. The blind view
of roads and the…

Lightweight digital imaging and communications in medicine image encryption for IoT system
Diagnosis in healthcare systems relies heavily on the use of medical images.
Images such as X-rays, ultrasounds, computed tomography (CT) scans,
magnetic resonance imaging (MRIs), and other scans of the brain and other
internal organs of patients…

LSKA-ID: A lightweight security and key agreement protocol based on an identity for vehicular communication
Recently, a huge effort has been pushed to the wireless broadcasting nature
in the open area. However, the vehicular ad hoc network (VANET) is
disposed to various kinds of attacks. Hence, keeping the security in VANET is
the most critical issue…

Estimating losses at 40-GHz downlink using non-meteorological techniques in heavy rain areas
The advancement of satellite communication has arisen tremendously where
higher capacity communications systems are needed. Most satellite
engineers are shifting to Ka, Q, and V-band upcoming since the low
frequencies such as below 10 GHz are…

Design and performance analysis of low phase noise LC-voltage controlled oscillator
Voltage controlled oscillator (VCO) offers the radio frequency (RF) system
designer a freedom to select the required frequency. Today’s wireless
communication system imposes a very stringent requirement in terms of
phase noise generated in VCO.…

Contrast modification for pre-enhancement process in multi contrast rubeosis iridis images
Existing researchers for rubeosis iridis disease focused on image
enhancement as a collective group without considering the multi-contrast of
the images. In this paper, the pre-enhancement process was proposed to
improve the quality of iris images…

Neuro-fuzzy-based anti-swing control of automatic tower crane
Controlling the position of the final load and the anti-swing control of the
loads during the operation of the tower crane are challenging tasks. These
are the most important control issues for safe operation, which are difficult
to achieve easily…

Dickson voltage multiplier with 1 to 6 stages for dual-band rectifiers (2.45/5.8 GHz) with low input power
This paper presents the design of highly efficient rectifiers that can operate
at WiFi frequencies (2.45 GHz and 5.8 GHz) and match low input power.
The designed dual-band rectifiers use multi-stage dickson voltage multipliers
(DVM) (from 1 to 6…

Experimental of vectorizer and classifier for scrapped social media data
In this study, we used several classifiers and vectorizers to see their effect on
processing social media data. In this study, the classifiers used were random
forest, logistic regression, Bernoulli Naive Bayes (NB), and support vector
clustering…
