Abstract Background: Thyroglossal duct cysts (TDC) are the most common congenital neck masses arising from the expansion of the epithelial tract remnants occurring during embryogenic thyroid migration. About 7% of the population have thyroglossal duct remnants. Clinical presentation is frequent in children, but adults can also present with thyroglossal duct cysts. Thyroglossal duct cysts may r...
This study aims to evaluate the effectiveness of reverse inclusion, which is a pilot in place where was conducted, line with views teachers, school principals and parents children special educational needs (SEN) typical developmental characteristics (TDC). Data were collected from total 46 participants (preschool teachers (N = 19); 3) working education kindergarten included whose have attended ...
This paper presents a performance analysis of self-interference cancellation methods in full-duplex large-scale multiple-input multiple-output (MIMO) systems. To support huge data traffic demands, we assume that the base station is assumed to be located in the small cell, giving it compact antenna arrays with a high channel correlation. From the analysis and the numerical results, the time-doma...
Thyroglossal duct cysts (TDCs) are cervical cysts occurring in approximately 7% of the population, mainly during childhood. The cyst usually presents itself as a painless, asymptomatic midline swelling below the hyoid bone. Differential diagnosis involves branchial cleft cyst, lymphoepithelial cyst, thyroid gland lesions, ranula and lymphadenopathy (of various etiologies). Sonogram (ultrasound)...
We investigate three parameterized algorithmic schemes for graphical models that can accommodate trade-offs between time and space: 1) AND/OR Adaptive Caching (AOC(i)); 2) Variable Elimination and Conditioning (VEC(i)); and 3) Tree Decomposition with Conditioning (TDC(i)). We show that AOC(i) is better than the vanilla versions of bothVEC(i) andTDC(i), and use the guiding principles of AOC(i) t...
This study examines the relationships between tourism destination competitiveness (TDC), empowerment, and support for among residents. It also role of empowerment as a mediator in relationship TDC residents’ tourism. A total 711 respondents were used. uses descriptive analysis, two-stage factor structural equation modeling (SEM). The results show that seven antecedents TDC, namely natural, cult...
A data driven multi-channel Time-to-Digital Converter (TDC) circuit with programmable resolution (25ps 800ps bin) has been implemented in a 0.25um CMOS technology. An on-chip PLL is used for clock multiplication up to 320MHz from an external 40MHz reference. A 32 element Delay Locked Loop (DLL) performs time interpolation down to 98ps. Finally, finer time interpolation is obtained using an on-c...
e report the design and characterisation of a 32x32 time to digital (TDC) converter plus single photon avalanche diode (SPAD) pixel array implemented in a 130nm imaging process. Based on a gated ring oscillator approach, the 10 bit, 50μm pitch TDC array exhibits a minimum time resolution of 50ps, with accuracy of ±0.5 LSB DNL and 2.4 LSB INL. Process, voltage and temperature compensation (PVT) ...
A receiver channel topology for a pulsed time-of-flight (TOF) laser rangefinder is presented. The designed compact IC receiver chip realized in 0.35 μm CMOS technology will include both a highperformance receiver channel and a time-to-digital converter (TDC). Its timing detection is based on the leading edge detection in the receiver channel. Amplitude-dependent timing error is compensated for ...
Previous results reported in the robotics literature show the relationship between time-delay control (TDC) and proportional-integral-derivative control (PID). In this paper, we show that incremental nonlinear dynamic inversion (INDI) — more familiar in the aerospace community — are in fact equivalent to TDC. This leads to a meaningful and systematic method for PI(D)-control tuning of robust no...
