We demonstrate super-sensitive multiphoton frequency-domain fluorescence lifetime images using the recently developed DC&1ω method by showing a two-fold improvement in imaging sensitivity compared to the conventional 1ω phase fluorometry.
Efficiency of induction machines can be determined using international efficiency test standards such as the IEEE standard 112, IEC 60034-2-1 and JEC 37. The methods presented in these standards involve tests such as the no-load test, lock rotor test and a dynamometer test. Performing the no-load test is simple with fewer requirements in terms of equipment. The dynamometer test and the locked rotor...
Circuit Breakers (CB) are widely used protection devices in High Voltage (HV) AC circuit. This condition makes the CB as one the fundamental HV apparatus. This situation encourages HV apparatus manufacturers to produce CB in different kinds of voltage level with different capability and performance. In this research paper, we proposed a modeling method which can be used to select appropriate commercially...
InAs/InP quantum-dash multi-wavelength laser is reported utilizing self-injection locking coherency boosting technique. Subcarrier controllability between 1–16 Fabry-Perot modes (1600–1610nm) with ∼−3–9dBm mode power is achieved. Thereafter, a successful 64 Gbit/s DP-QPSK data transmission is demonstrated via a single self-injection locked mode over 20km single-mode-fiber.
To create confusion in ciphertexts, encryption processes depends upon nonlinear mappings. This nonlinear mapping can be achieved by a process known as substitution. In a secure encryption algorithm, substitution plays a key role during confusion stage of encryption algorithms. In this work, we present a novel chaos-based substitution box that can be utilized in the encryption processes for securing...
The equivalent circuit method is one of the promising methods for induction machine efficiency estimation. Conventionally, parameters of the machine are usually obtained from a no-load and lock rotor test. For in-service induction machines, performing these tests may not be possible without disrupting the machine operations. In this paper, a nonintrusive equivalent circuit based efficiency estimation...
Recently, ultrasound imaging of muscle contractions has been used by several research groups to infer volitional motor intent of the user, and has shown promise as a novel muscle computer interface. Learning spatiotemporal features from ultrasound image sequences is challenging because of deformations introduced by probe repositioning. The image features are sensitive to probe placement and even small...
Electroencephalogram (EEG) data is a set of brain signals recorded by special EEG headsets. These signals reflect the cortical electrical activity. The technique for utilization of EEG data has emerged to be a safe and portable non-invasive Brain Computer Interface (BCI) that can easily be used for studying the human cognitive states. In this paper we have focused on studying the pilot's cortical...
Innovative advance dielectric materials were utilized to fabricate novel thin film capacitor device. This includes ceramic and polymeric material combination which is considered to enhance the dielectric polarization. The dielectric film presented in the study focused on PbTiO3/PVDF-TrFE which was prepared through layer-by-layer spin coating deposition method. The PVDF-TrFE coating was aimed to encapsulate...
Retrieving information from movies is becoming increasingly demanding due to the enormous amount of multimedia data generated each day. Not only it helps in efficient search, archiving and classification of movies, but is also instrumental in content censorship and recommendation systems. Extracting key information from a movie and summarizing it in a few tags which best describe the movie presents...
Waveguide evanescent fields enable lysing of selected red blood cells. Cells are trapped on waveguides and are lysed by rapidly reducing the trapping forces. Red blood cells of different age require different levels of lysing power, allowing selective lysing of crenate cells.
This paper presents the design of a subwavelength electromagnetic band gap (EBG) isolator for a biomedical repeater device. The repeater device is meant to amplify the attenuated RF signal sent from reader antenna and retransmits it to a miniature implant sensor. The EBG isolator working at UHF RFID frequency of 900 MHz occupies an area of 3.1 cm × 2 cm. It increases isolation between orthogonal loops...
A fully wireless implantable system can be used for long-term monitoring of intracranial pressure. In this type of system, an implant is placed under the skull and monitored pressure is transmitted wirelessly outside the skull. Moreover, the implant is powered through an inductive coupling. To avoid any infection and damage to the implant, the implant should be coated with biocompatible material....
An indoor 100 Gb/s wireless communication is demonstrated using external coherent injection-locking of InAs/InP Quantum-dash (QDash) laser. Receiver power sensitivities of −18.4 dBm and −17.4 dBm at ∼1621.3 nm are observed after propagating along a 2 m and 4 m indoor free-space channels, respectively, while adopting dual polarization quadrature phase shift keying (DP-QPSK) modulation scheme. Moreover,...
Wind energy has become an attractive alternative to satisfy the ever-growing energy demands worldwide. One important factor that contributes to efficient energy harnessing from a wind farm is the selection of appropriate wind turbines for a specific site. This paper addresses this important issue through a goal programming based multi-criteria wind turbine selection approach. The approach considers...
We report, for the first time to our knowledge, on the self-injection locking of chirped InAs/InP quantum-dash (QDash) lasers with ∼6.5 nm locked Fabry-Perot mode tunability, in the L-band wavelength emission. The modes exhibited ∼30 dB side mode suppression ratio (SMSR) with ∼8–9 dBm mode power. Generally, the locked mode SMSR and tunability is found to be limited by the L-band amplifier amplified...
An implantable pressure monitoring system is a compelling approach to home monitoring of intracranial pressure in the long term. In our approach, an on-body unit powers a cranially concealed system where a piezoresistive element senses the pressure. A data transmission unit built in the same platform emits a signal at a pressure dependent frequency through a miniature far field antenna. In this work,...
Complexity of an encryption algorithm is highly dependent on nonlinear components that drive actual security. Only nonlinear component in all traditional encryption algorithms is mainly Substitution Box (S-Box). In block ciphers, the relationship between plaintext amd ciphertext is abstruse via confusion operation. Due to the high sensitivity of initial conditions, utilization of chaotic equations...
Macular edema (ME) is trending to be an increasing disease among the working adult group that causes retinal swelling within sub-retinal layers due to accumulation of protein deposits. Optical coherence tomography (OCT) imaging technique gives a complete cross-sectional view of the retina and helps in early detection of ME.
