Low speed wind tunnel investigation of the aerodynamic and acoustic performance of several sonic inlet takeoff and approach geometries [PDF]
A series of tests was conducted to determine the aerodynamic and acoustic performance of several sonic inlet takeoff and approach geometries. The effects of inlet lip shape and diffuser length were also investigated.

Non-uniform phase filter for Tiangong-2 Interferometric Imaging Radar Altimeter
The Journal of Engineering, 2019 The interferometric imaging radar altimeter (InIRA) on-board Chinese Tiangong-2 space laboratory is a Ku-band interferometric radar whose major aim is to measure the wide-swath ocean topography. Unlike traditional interferometric synthetic aperture radar

ISOTROPY ANALYSIS OF METAMATERIALS
Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2015 Metamaterials – artificial periodic structures with subwavelength feature sizes – can be characterized with macroscopic electromagnetic properties, like refractive index and wave impedance, just like homogeneous materials.

Aeroacoustic performance of scale model sonic inlets [PDF]
A low speed wind tunnel was used to evaluate the inflight aeroacoustic performance of several single- and multiple-passage sonic inlets. Takeoff and approach geometries were tested, and the effects of inlet lip and diffuser design were determined ...

Combinatorial Designs with Two Singular Values II. Partial Geometric Designs [PDF]
In this and an earlier paper [17] we study combinatorial designs whose incidence matrix has two distinct singular values.These generalize (v, k, ë) designs, and include uniform multiplicative designs and partial geometric designs.Here we study the latter,

A PRESENTATION OF DESARGUES’ THEOREM APPLYING THE DESCRIPTIVE GEOMETRY RULES
Journal of Industrial Design and Engineering Graphics, 2006 This paper presents Desargues’ theorem in two ways: – the solution by incidence and succession; - the solution by the application of the descriptive geometry rules.
