the study of interactions of jet into cross flow at different longitudinal and transverse angles ofjet was studied. the following components were designed and constructed: a low velocity windtunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jetinjection, and a spatial rake to measure the total pressure. the tests were carried out atlongitudinal (α...

This study presents the characteristics and performance of a motor at operating point based on pulse-width modulation (PWM). PWM is used in modulating output voltage three-phase inverter. The technique has advantages disadvantages depending system size range. For example, some discontinuous (DPWM) techniques are advantageous low-cost systems because they can reduce number switches. Some complic...

Abstract The IPCC sixth assessment report forecasts sea level rise (SLR) of up to 2 m along coasts by 2100 relative 1995–2014 following business as usual (SSP585) scenarios. Geoengineering may reduce this threat. We use five Earth System Models simulations two different solar geoengineering methods (solar dimming and stratospheric sulfate aerosol injection), that offset radiative forcing differ...

OBJECTIVE The offset connector can allow medial and lateral variability and facilitate intralaminar screw incorporation into the construct. The aim of this study was to compare the biomechanical characteristics of C7 intralaminar screw constructs with and without offset connector using a three dimensional finite element model of a C6-7 cervical spine segment. METHODS Finite element models rep...

OBJECTIVE The identification of sentinel lymph nodes (SLNs) near injection sites is difficult because of scattered gamma rays. The purpose of this study was to investigate the optimal energy windows for elimination of scattered gamma rays in order to improve the detection of SLNs. METHODS The clinical study group consisted of 56 female patients with breast cancer. While the energy was centred...

Owing to the strong optical absorption of Sb2Se3, building heterojunctions (HJs) by using thin-layer Sb2Se3 and other two-dimensional (2D) materials is critical design applications ultrathin optoelectronic devices. However, preparation HJs transition metal dichalcogenide (TMDC) thin layers still challenging. Herein, a chemical vapor deposition (CVD) method was used prepare monolayer MoS2(1L-MoS...

We demonstrate coherent averaging of the multi-heterodyne beat signal between two quantum cascade laser frequency combs in a master-follower configuration. The are mutually locked by acting on drive current to control their relative offset and radio-frequency extraction injection locking intermode stabilize mode spacing difference. By implementing an analog common-noise subtraction scheme, redu...

Existing vision based supervised approaches to lateral vehicle control are capable of directly mapping RGB images the appropriate steering commands. However, they prone suffering from inadequate robustness in real world scenarios due a lack failure cases training data. In this paper, framework for more robust and scalable model is proposed. The only requires an unlabeled sequence images. traine...

An algorithm is presented to approximate planar offset curves within an arbitrary tolerance > 0. Given a planar parametric curve C(t) and an offset radius r, the circle of radius r is first approximated by piecewise quadratic Bézier curve segments within the tolerance . The exact offset curve Cr(t) is then approximated by the convolution of C(t) with the quadratic Bézier curve segments. For a p...
