Slot Maze A

چکیده
it cannot be removed from the board except at the ends of the course. This makes the test practically "fool proof" and eliminates all necessity for negative instructions. An entire series of these tests is being devised and standardized. This article, as a preliminary statement, is confined to a report on the use of the first of the series, Slot Maze A, in testing 1304 children ranging in age from four to nine.

An Ultralow Cross-Polarization Slot Array Antenna in Narrow Wall of Angled Ridge Waveguide
A low cross-polarization slot array antenna in the narrow wall of ridge waveguide is presented. A non-angled slot which is created in the narrow wall of the ridge waveguide is considered to be used as radiating resonant slot. The normalized resistance and normalized reactance curves are presented for design purposes. A six element slot array waveguide antenna with ridges on its narrow wall is t...
متن کاملInvestigation of unbalanced magnetic force in permanent magnet brushless dc machines with diametrically asymmetric winding
The purpose of this paper is the calculation of Unbalanced Magnetic Force (UMF) in permanent magnet brushless DC (PMBLDC) machines with diametrically asymmetric winding and investigation of UMF variations in the presence of phase advance angle. This paper presents an analytical model of UMF in surface mounted PMBLDC machines that have a fractional ratio of slot number to pole number. This model...
متن کاملCPW-Fed Circularly Polarized Slot ANTENNA with Elliptical-Shaped Patch for UWB Applications
A new design of coplanar waveguide (CPW)-fed antenna with circular polarization (CP) and excellent impedance matching is presented. In this design a pair of circular-shaped slits is applied to opposite corners of the slot for enhancing the impedance matching and realizes bandwidth of 134.43% across 2.98-15.20 GHz for VSWR≤2. Furthermore this structure exhibits axial ration bandwidth (ARBW) of 3...
متن کاملکنترل و کاهش آب شستگی موضعی در پایههای پل با مقاطع مستطیلی گرد گوشه با استفاده از شکاف
The use of slot through a pier is a new method proposed to control local scour at bridge piers. In this study, control of local scour at bridge pier is studied using 20 pier models under clear water conditions. The models consist of one circular pier without slot, three round-nosed piers without slot, and 16 piers with slot. Two slot lengths were chosen (yl=b and yl=2b, where y1 is the length o...
متن کاملExperimental Investigation into the Hydrodynamics Effects of Slot Film Cooling on a Cylindrical Model
An experimental study of hydrodynamics of film cooling is performed by using a single longitudinal slot on a cylindrical model simulated to the leading edge of the gas turbine blade. The model is set up into the test section of an open-circuit induced flow wind tunnel which provides the main flow. The injected air, as a secondary film flow, produced from a high pressure compressor is considered...
