Mode Vertices and Mode Graphs.
… distance to a furthest vertex from <em>v</em>. A mode vertex of a connected graph, <em>G</em>, is a vertex whose eccentricity occurs as often in the eccentricity sequence of <em>G</em> as the eccentricity of any other vertex. The mode of a graph, <em>G</em>, is the subgraph induced by the mode …

Fracture Characteristics of Asphalt Concrete in Mode I, Mode II, and Mixed-Mode
… above were used to develop and validate a new Mode II test for asphalt concrete. No previous literature was found that attempted to capture Mode II fracture energy in asphalt concrete, so a test was developed from an extensive review of Mode II tests in the fields of metal, plastic, and PCC. …

Dispersion-managed Breathing-mode Semiconductor Mode-locked Ring Laser
A novel dispersion-managed breathing-mode semiconductor mode-locked ring laser is developed. The "breathing-mode" designation derives from the fact that intracavity pulses are alternately stretched and compressed as they circulate around the ring resonator. The pulses are stretched before entering …

Mode-mode interference in optical fibers: analysis and experiment
Interference between the modes of an optical fiber generates specific mode (intensity) patterns which get modulated by disturbances in the optical fiber system. Mode-mode interference has been analyzed from first principles and a model based on differential phase modulation presented. Mode-mode …

Adaptive Mode Control in Few-Mode and Highly Multimode Fibers
Few-mode fibers (FMFs) and multimode fibers (MMFs) can provide much higher data-carrying capacities compared with single-mode fibers. But in order to achieve this goal, one must address the challenge of intermodal coupling and dispersion. Therefore the ability to accurately control the optical …

SOUND MODE APPLICATION
… he/she should manually modify the sound mode (ring, vibrate, silent). So, it’s slightly inconvenient to constantly monitor whether the phone is in general or silent mode. Sometimes user might forget to switch the mobile mode and may create a disturbance in the classroom or in the work …

Selective mode coupling in microring resonators for single mode semiconductor lasers
Single mode semiconductor laser diodes have many applications in optical communications, metrology and sensing. Edge-emitting single mode lasers commonly use distributed feedback structures, or narrowband reflectors such as distributed Bragg reflectors (DBRs) and sampled grating distributed Bragg …

Mode I and Mode II Measurements For Stiction Failed Micro-Electro-Mechanical Systems
… have constructed an apparatus to determine the Mode I, II, and III interfacial adhesion energies of MEMS devices failed on a substrate. Though our method is general, we are specifically focused on devices created using the SUMMiT V process. An apparatus has been constructed that has 8 …

Exploring the properties of a combined differential-mode equalizer and common-mode filter
… This thesis analyzes a combination differential-mode equalizer and common-mode filter (DME-CMF) realized on a two-layer microstrip board. Measurements up to 25 GHz are taken to explore the functionality of this device at and above the design frequency. The basics of S-parameters are reviewed, and …

Theoretical explanations of I-mode impurity removal and H-mode poloidal pedestal asymmetries
… optimum tokamak performance. High confinement mode operation was discovered 35 years ago to almost quadruple fusion power, and later explained by turbulence reduction by sheared flows. Less than a decade ago, improved mode operation was discovered to have the same desirable property, while …

Separation of the common-mode and the differential-mode conducted electromagnetic interference noise
… which can be used to decipher the differential-mode (DM) noise and the common-mode (CM) noise from the total noise. A noise separator hardware is built and tested. The results show that at least 50 dB rejection to either DM or CM noise is achieved for frequency ranging from 10 KHz to 30 MHz. …

Transformer Shielding Technique for Common Mode Noise Reduction in Switch Mode Power Supplies
Switch mode power supplies are widely used in different applications. High efficiency and high power density are two driving forces for power supply systems. However, high dv/dt and di/dt in switch mode power supplies will cause severe EMI noise issue. In a typical front-end converter, the EMI …

Experimentation of Mode I and Mode II Fracture of Uni-Directional Composites and Finite Element Analysis of Mode I Fracture Using Cohesive Contact
… One of the most prevalent and limiting mode of failure within composite laminates is delamination, since it not only reduces a structures stiffness and strength, but can be very difficult to detect without the use of special non-destructive equipment. Industry testing organizations have …
