Abstract:

Post-reinforcement pause was examined to determine the reinforcing value of a win, loss, and a loss disguised as a win (LDW) for gamblers at multi-line video slot machines. The study was conducted in naturalistic settings across a variety of participants, age 21 years and older. The length of the post-reinforcement pause was recorded using a stopwatch for one win, one loss, and one LDW for each participant and was measured by recording the time between the outcome delivery and the initiation of the next spin. The different times were evaluated to determine which of the three resulted in the lo

Abstract:

The aim of this study is to investigate the effects of changes in the physical parameters of tapered slot antennas (TSA) on their radiation characteristics and also to explore the possibility of reconfiguration in the radiation pattern of TSA by switching between two different types of tapering. There are mainly three physical parameters that affect the radiation pattern of TSAs. These are antenna length, aperture width and the ground extension. After designing a wideband microstrip line to slot line transition, the effect of antenna parameter variations on the beamwidth and sidelobe level of

In this thesis the possibility of using radial line slot array (RLSA) antennas to provide low profile isoflux radiation patterns suitable for use as circularly-polarized tracking, telemetry & command (TT&C) antennas on low Earth orbit (LEO) satellites is investigated. The RLSA antenna elements are slot pairs located on concentric circles on the top plate of a radial waveguide. Conventional synthesis techniques cannot be used due to the fact that the RLSA antenna is a non-uniformly spaced array, the elements do not all have the same orientation, and the excitation amplitudes and phases are link

Abstract:

A descriptive analysis was conducted to examine the influence minimum bets 30 credits and 50 credits had on the actual bets wagered on slot machines that operated on fixed-lines. Results suggested that slots with the lower minimum bets correlated with higher wagers.

On average, the participants who played the slot machines with a minimum bet of 30 credits actually bet more than the participants who played the slo

Those are short-circuited parallel coupled bandpass filter, open-circuited parallel coupled bandpass filter, a diplexer and a stop band improvement UWB Bandpass filter, respectively. The response characteristic of short-circuited and open-circuited parallel coupled lines are exhibited all stop frequency response and the stop band appeared at 3f0 and 2f0, respectively. The central frequencies of open-circuited and short-circuited parallel coupled lines are

碩士<br>國防大學理工學院<br>航空太空工程碩士班<br>99<br>A dual-band circularly polarized (CP) printed slot antenna with a tunable frequency-ratio range is proposed in this thesis. The proposed antenna design which can find applications on UAV (Unmanned Aerial Vehicle) features a ring slot etched on ground plane, the two coupling slots beneath the ring slot, the embedded spurs-like-shaped strip in the ring slot, a double-bend feeding line and a rectangular pad connected with the feeding line for improving the impedance match of the lower frequency band. The spur-like-shaped strip can be employed to create a highe

Abstract:

Yes<br>An effective method is presented for suppressing mutual coupling between adjacent radiating elements which is based on metasurface isolation for MIMO and synthetic aperture radar (SAR) systems. This is achieved by choking surface current waves induced over the patch antenna by inserting a cross-shaped metasurface structure between the radiating elements. Each arm of the cross-shaped structure constituting the metasurface is etched with meander-line slot (MLS). Effectiveness of the metasurface is demonstrated for a2×2antenna array that operates over six frequency sub-bands in X, Ku and K

Abstract:

No<br>To mitigate potential interferences with coexisting wireless systems operating over 3.3-3.6 GHz, 5.15-5.35 GHz, or 5.725-5.825 GHz bands, four novel band-notched antennas suitable for ultra-wideband (UWB) applications are proposed. These include UWB antennas with a single wide notched band, a single narrow notched band, dual notched bands, and triple notched bands. Each antenna comprises a half-circle shaped patch with an open rectangular slot and a half-circle shaped ground plane. Good band-notched performance is achieved by using high permittivity and low dielectric loss substrate, and

Abstract:

yes<br>A new low-cost dual-segmented dielectric resonator (DR) antenna design is proposed for wideband applications in the X-band region. Two DRs coupled to an S-shaped slot introduce interesting features. The antenna performance was characterized in terms of the reflection coefficient, gain, and radiation pattern, and detailed simulation studies indicate excellent antenna performance from 7.66 GHz to 11.2 GHz (37.5% fractional bandwidth) with a maximum gain of 6.0 dBi at 10.6 GHz while the fabricated prototype has a matched bandwidth from 7.8 GHz to 11.85 GHz (41% fractional bandwidth) and ma

Abstract:

abstract: Kinetic inductance springs from the inertia of charged mobile carriers in alternating electric fields and it is fundamentally different from the magnetic inductance which is only a geometry dependent property. The magnetic inductance is proportional to the volume occupied by the electric and magnetic fields and is often limited by the number of turns of the coil. Kinetic inductance on the other hand is inversely proportional to the density of electrons or holes that exert inertia, the unit mass of the charge carriers and the momentum relaxation time of these charge carriers, all of w

In order to solve for the blind spot on the signal coverage, designs of Yagi-like multilayered slot antennas will be proposed. The high gain antenna design is used to solve the problem. In the introduction, the principle of the Yagi antenna will be surveyed and understood. And, then a design of a slot Yagi-like multilayered antenna and a design of dual-polarization Yagi-like multilayered slot antenna will be proposed: In the first case, a design of slot Yagi-like multilayered anten

Abstract:

Human malignant melanoma is a highly aggressive and drug-resistant tumour of neuro-ectodermal origin. Tumor heterogeneity, undifferentiated molecular signatures, and increased tumorigenicity of melanoma subsets with embryonic-like differentiation plasticity, strongly suggests the presence and involvement of cancer a stem cells in the initiation and propagation of melanoma. Parallel to the role that normal stem cells play in organogenesis, cancer stem cells are thought to be crucial for tumorigenesis. Many investigators, indeed, propose that melanoma stem cells (MSCs) may be responsible for tum
