GPU or VGA (graphic processing unit) is a vital component of computers and laptops, used for tasks such as rendering videos, creating game environments, compiling large amounts code. The price GPU/VGA has fluctuated significantly since the start COVID-19 pandemic in 2020, due part to increased demand GPUs remote work online activities. Furthermore, accurate forecasting can have broader implicat...

During the last decade, there has been massive growth in construction of large residential complexes and apartment blocks Tirana. Urban density is increasing due to fact that traditional low-story villas are demolished, space former private gardens used for new with high built ratio. The public areas which adequate such dense cities not provided therefore residents have a tendency spend more ti...

This paper introduces a system that detects the presence or absence of the mandatory medical mask in the operating room. The overall objective is to have as few false positive face detections as possible without losing mask detections in order to trigger alarms only for healthcare personnel who do not wear the surgical mask. The medical mask detection is performed with two face detectors; one o...

The environmental irritant chloroform, a naturally occurring small volatile organohalogen, briefly became the world’s most popular volatile general anesthetic (VGA) before being abandoned because of its low therapeutic index. When chloroform comes in contact with skin or is ingested, it causes a painful burning sensation. The molecular basis for the pain associated with chloroform remains unkno...

It is a challenge to implement loss-of-signal (LOS) circuit with wide threshold voltage range that insensitive temperature. This paper presents new wide-range threshold-programmable LOS detector full temperature compensation for application in 25Gb/s high-speed optical communication receivers. The programmable of the achieved by adjusting peak and gain variable amplifier (VGA). detection accura...

This paper presents a fast received signal strength indicator (RSSI) circuit for wireless communication application. The proposed circuit is developed using power detectors and an analog-to-digital converter to achieve a fast settling time. The power detector is consisted of a novel logarithmic variable gain amplifier (VGA), a peak detector, and a comparator in a closed loop. The VGA achieved a...

Introduction In my previous report I discussed the realtime behaviour of electronic mixers capable of mixing a PAL with a VGA image, downconverting the mixed images to PAL format. We concluded that the behaviour, especially in the temporal domain, is suboptimal. If possible, we would like get better real-time behaviour. One possibility is to mix these images optically. This report discusses how...

Wireless access vehicle environment (WAVE) architecture of intelligent transportation system has been standardized in IEEE 802.11p standard and it is going to be widely deployed in many roadway environments in order to provide convenient services. However, the IEEE 802.11p contention-based medium access control protocol would significantly downgrade transmission efficiency between road side uni...

This paper proposes a new architecture for transconductance (Gm)-based variable-gain amplifiers (VGA) that is better suited for multi-standard radio receivers than the classical two-Gm structure: its bandwidth and linearity are largely independent of the gain setting and both the gain range and the bandwidth can be programmed through digital controls. Unlike the classical structure that uses tw...
