F-Shaped Monopole Antenna
(IEEE, 2017)In this paper, effects of F antenna arm length on the frequency, gain and s11 values are studied. The arms and the total length of the F determine the resonance frequency of the antenna. The inverted F shaped antennas are ... -
Fall detection for elderly people using depth video data obtained by kinect
(2013-08)Automatic detection of unusual events such as falls is very important especially for elderly people living alone. Real-time detection of these events can reduce the health risks associated with a fall. There has been a ... -
Fast and efficient circuit topologies for finding the maximum of n k-bit numbers
(IEEE, 2014-08-01)Finding the value and/or index of the maximum (or minimum) element of a set of n numbers (each with k-bits) is a fundamental arithmetic operation and is needed in many applications. This paper proposes several maximum-finder ... -
Fast incremental least square pose estimation for hardware implementation with rolling shutter camera
(IEEE, 2020-10-05)6 DoF position and orientation estimation is vital for many real-time applications. It is essential to meet low latency, high accuracy and reliability requirements, especially when used for real-time haptic feedback ... -
Fast multiplier generator for FPGAs with LUT based partial product generation and column/row compression
(Elsevier, 2017)We present a new parallel integer multiplier generator for FPGAs. It combines (i) a new Generalized Parallel Counter (GPC) grouping algorithm for column compression with (ii) a LUT based partial product generation, is (iii) ... -
Fast parallel prefix logic circuits for n2n round-robin arbitration
(Elsevier, 2012-08)An n2n round-robin arbiter (RRA) searches its n inputs for a 1, starting from the highest-priority input. It picks the first 1 and outputs its index in one-hot encoding. RRA aims to be fair to its inputs and maintains ... -
Fast two-pick n2n round-robin arbiter circuit
(IEEE, 2012-06)A regular (one-pick) round-robin arbiter circuit picks one active requester (if any) out of n requesters. A two-pick round-robin arbiter selects up to two requesters. An n2n two-pick round-robin arbiter indicates the picked ... -
Fast, secure, and remote multiboot of FPGAs
(2012-09)The purpose of this thesis is to develop an efficient framework to implement secure FPGA-based (Field Programmable Gate Array) systems. An FPGA is a reconfigurable device that has the ability to adapt the hardware during ... -
Fast-decodable MIMO HARQ systems
(IEEE, 2015-05)This paper presents a comprehensive study on the problem of decoding complexity in a Multi-Input Multi-Output (MIMO) Hybrid Automatic Repeat reQuest (HARQ) system based on Space-Time Block Codes (STBCs). We show that there ... -
Feedback-free adaptive modulation selection algorithm for FSO systems
(IEEE, 2021-09)Free space optical (FSO) communication systems experience turbulence-induced fading. As a possible solution to mitigate the effects of fading, adaptive transmission that allows the adjustment of transmission parameters ... -
Finite-SNR diversity gain analysis of FSO systems over gamma-gamma fading channels with pointing errors
(IEEE, 2021-06)Free space optical (FSO) communication systems are subject to turbulence-induced fading as a result of fluctuations in the refractive index. Gamma-Gamma (GG) distribution is commonly used in the literature to characterize ... -
Finite-SNR diversity-multiplexing tradeoff for network coded cooperative OFDMA systems
(IEEE, 2017-03)Network-coded cooperation (NCC) is an effective method to improve the throughput efficiency in cooperative wireless networks. The combined use of orthogonal frequency division multiplexing (OFDM) with NCC has been further ... -
Finite-SNR DMT analysis for multisource multirelay NCC systems with imperfect CSI
(IEEE, 2016)Network coded cooperative (NCC) systems have recently attracted attention with their high spectral and power efficiency. In this paper, we investigate the information theoretical limits of NCC systems in the presence of ... -
Flexibility assessment tool by failure-based uncertainty management in power systems
(IEEE, 2019)Flexibility in power systems operations is the capability to operate the system under secure conditions even after a sudden change in the system conditions. One of the sudden change may be considered as the failure of ... -
Flexible architecture of relay-based wireless network for network lifetime extension with hop-count constraint
(Informa Group, 2011)In relay-based wireless networks, messages need to be forwarded via intermediate relay mobile terminals (MTs). However, because of various transmission distances and unbalanced traffic load, some relay MTs may tend to drain ... -
Flexible generalized spatial modulation for visible light communications
(IEEE, 2021-01)Adaptive spatial modulation (ASM) varies the modulation size across the transmit light-emitting diodes (LEDs) to improve the overall spectral efficiency of visible light communication (VLC) systems. This article proposes ... -
A flexible OLED VLC system for an office environment
(IEEE, 2020)The potential use of flexible substrate-based organic light emitting diodes (OLEDs) as curved or rolled lighting sources offers news opportunities for the implementation of visible light communications (VLC) in indoor ... -
Flexural wave-based soft attractor walls for trapping microparticles and cells
(Royal Society of Chemistry, 2021-02-07)Acoustic manipulation of microparticles and cells, called acoustophoresis, inside microfluidic systems has significant potential in biomedical applications. In particular, using acoustic radiation force to push microscopic ... -

Formant position based weighted spectral features for emotion recognition
(Elsevier, 2011)In this paper, we propose novel spectrally weighted mel-frequency cepstral coefficient (WMFCC) features for emotion recognition from speech. The idea is based on the fact that formant locations carry emotion-related ...
