Device-to-device communication in 5G cellular networks: challenges, solutions, and future directions
(IEEE, 2014-05)In a conventional cellular system, devices are not allowed to directly communicate with each other in the licensed cellular bandwidth and all communications take place through the base stations. In this article, we envision ... -
Diffusion-based approach to deploying wireless sensor networks
(Inderscience, 2010)An important objective of Wireless Sensor Networks (WSNs) is to reliably sense data about the environment in which they are deployed. Reliability in WSNs has been widely studied in terms of providing reliable routing ... -
Digital data integration project between a DSO and a university for sustainability and efficiency
(IEEE, 2022)Digitization in the energy sector enables big data analysis that can lead to large-scale energy efficiency due to the size of the sector and thus getting closer to sustainability targets. With a digital data integration ... -
Disposable cartridge biosensor platform for portable diagnostics
(SPIE , 2017)We developed two types of cantilever-based biosensors for portable diagnostics applications. One sensor is based on MEMS cantilever chip mounted in a microfluidic channel and the other sensor is based on a movable optical ... -
Distance and power based experimental verification of channel model in visible light communication
(IEEE, 2019)In this work, a channel model for line-of-sight (LOS) in visible light communication is elaborated. In the proposed channel model, there is no optical component, such as filter or lens, between the transmitting LED and the ... -
Distributed MIMO for Li-Fi: Channel measurements, ray tracing and throughput analysis
(IEEE, 2021-08-15)LiFi has been considered as a promising candidate for future wireless indoor networks. The IEEE P802.15.13 and P802.11bb standardization groups agreed upon channel models generated using the non-sequential ray tracing ... -
Diversity gain analysis of underwater vertical MIMO VLC links in the presence of turbulence
(IEEE, 2019)To satisfy the demands of high data rate underwater applications such as image and real-time video transmission, underwater visible light communication (UVLC) has emerged as an alternative to acoustic signaling. One of the ... -
Diversity-multiplexing trade-off in coherent free-space optical systems with multiple receivers
(IEEE, 2010-12)In this paper, from an information theory point of view, we investigate the performance of a coherent freespace optical (FSO) communication system with multiple receive apertures over atmospheric turbulence channels. Our ... -
Diversity-multiplexing tradeoff for log-normal fading channels
(IEEE, 2016-07)Although there has been a growing interest on the study of diversity-multiplexing tradeoff (DMT), the existing works are mostly restricted to the outcomes reported for Rayleigh, Rician, and Nakagami fading channels. In ... -
Diversity-multiplexing tradeoff for network coded cooperative OFDMA systems
(IEEE, 2015)Network coded cooperation (NCC) is an effective method to improve the throughput efficiency in cooperative wireless networks. In an effort to have further gains over the initial works, which build upon the assumption of ... -
DMT analysis and optimal scheduling for two-hop parallel relay networks
(Elsevier, 2021-06)Two-hop parallel networks with half-duplex relays over quasi-static Rayleigh fading channels are considered. Assuming relays have only local channel state information, optimal communication schemes for these networks in ... -
DMT analysis of coherent free-space optical systems over atmospheric turbulence channels
(IEEE, 2010)In this paper, we investigate the diversity-multiplexing tradeoff (DMT) performance of a coherent free-space optical (FSO) communication system with multiple receive apertures over atmospheric turbulence channels. Our study ... -
DMT analysis of multi-hop coherent FSO communication over atmospheric channels
(IEEE, 2011)In this paper, we investigate the diversity-multiplexing tradeoff (DMT) of a multi-hop coherent free-space optical (FSO) system over atmospheric channels. We consider a relay-assisted FSO system with decode-and-forward ... -
Dopamine detection using mercaptopropionic acid and cysteamine for electrodes surface modification
(Sciendo, 2018)Gold electrodes are often not suitable for dopamine measurements as dopamine creates a non-conducting polymer layer on the surface of the electrodes, which leads to increased amount of electrode passivity with the gradual ... -
Double U slot patch antenna
(IEEE, 2016)In this paper, we aim to design to simulate `double u slot patch antenna'. Our simulation and experimental investigation aimed to understand the behavior of the two U-slots. It can be used in WiMAX compliant communication ... -
A double-needle gold-silver electrodes continuous glucose monitoring device
(Elsevier, 2023-06)Objectives: Diabetes is a serious, long-term disease and the use of continuous glucose monitoring sensors can reduce reliance on other painful invasive blood testing methods such as the finger blood glucose test. According ... -
Down-conversion emission profile characterisation via camera
(Optica Publishing Group, 2020-12-14)We present a method to improve the brightness and collection efficiency of the spontaneous parametric down-conversion source by monitoring the mode shape using camera and correcting it with collection optics. -
Drizzle attenuation model for visible and infrared wavelengths
(IEEE, 2022)In an outdoor environment, the transmitted optical signal is affected by the atmospheric particles that may scatter or absorb light such as drizzle, rain, snow, fog, and aerosols. Various earlier studies have attempted to ... -
Dual resonance proximity coupled patch antenna
(IEEE, 2018-05-24)In this paper there are four different shape of proximity patch antennas (straight, trimmed, trapezoid and ribbon). The minimum input match achieved with the straight proximity patch antenna as -39.68 dB. The maximum gain ... -
Dual-band gemini-shaped microstrip patch antenna for C-band and X-band applications
(IEEE, 2017)In this paper, a novel single-layer Gemini-shaped patch antenna with dual-band characteristics is presented. The proposed patch antenna, with design operating frequencies of 6.53 GHz and 8.62 GHz, is targeted for applications ...
