...Computer Engineering, The University of Akron, OH 44325-3904, USA b Department of Polymer Science, The University of Akron, OH 44325-3909, USA ABSTRACT Several classes of computational methods are available for computer simulation of electromagnetic wave propagation and scattering at optical frequencies: Discrete Dipole Approximation, the T-matrix − Extended Boundary Condition methods, the Multiple Multipole Method, Finite Difference (FD) and Finite Element (FE) methods in the time and frequency domain, and others. The paper briefly reviews the relative advantages and disadvantages of these simulation tools and contributes to the development of FD methods. One powerful tool – FE analysis − is applied to optimization of plasmon-enhanced AFM tips in apertureless near-field optical microscopy. Another tool is a new FD calculus of “Flexible Local Approximation MEthods” (FLAME). In this calculus, any desirable local approximations (e.g. scalar and vector spherical harmonics, Bessel functions, plane waves, etc.) are seamlessly incorporated into FD schemes. The notorious ‘staircase’ effect for slanted and curved boundaries on a Cartesian grid is in many cases eliminated – not because the boundary is approximated geometrically on a fine grid but because the solution is approximated algebraically by suitable basis functions. Illustrative examples include problems with plasmon nanoparticles and a photonic crystal with a waveguide bend; FLAME achieves orders of magnitude higher accuracy than...

Bernido and l\faria Victoria Carpio-.Rernido Research Center for Theoretical Physics Central Visayan Institute Foundation Jagna, Bohol 6308, Philippines The Ascending Levels of Learning and Pedagogical ~1axims that could guide effective teaching of physics are presented. As an example of how these may be applied, the Dynamic Learning Prof:,lfam (DLP) of the Central Visayan Institute Foundation is briefly discussed. The DLP, together with 21st century technology, provides a scenario where the perennial lack of high school physics teachers in the Philippines can be bypassed. Introduction The breadth of topics that may be covered in teaching physics can be extremely wide. After all, physics probes the smallest things in the universe (the quarks and leptons), aiJ the way up to the "biggest" subject one can think of-the birth, death, and fate of the universe itself. One definition for physics states that it is the study of matter and energy. Most everything in the universe is either matter or energy, and this can make physics quite interdisciplinary. No wonder, therefore, that sub-areas in physics may be referred to as Biophysics, Geophysics~ Chemical Physics, Mathematical Physics, Astrophysics, Nuclear Physics, Econophysics, etc., and one also has the physics of sports, the physics of art, and so on. Because of its breadth, there is always...

To achieve the nano-watt range power consumption, an ultra-low power design strategy has been utilized, imposing maximum simplicity on the ADC architecture, low transistor count and matched capacitive DAC with a switching scheme which results in full-range sampling without switch bootstrapping and extra reset voltage. Furthermore, a dual-supply voltage scheme allows the SAR logic to operate at 0.4 V, reducing the overall power consumption of the ADC by 15% without any loss in performance. The ADC was fabricated in 0.13- m CMOS. In dual-supply mode (1.0 V for analog and 0.4 V for digital), the ADC consumes 53 nW at a sampling rate of 1 kS/s and achieves the ENOB of 9.1 bits. The leakage power constitutes 25% of the 53-nW total power. Index Terms—ADC, analog-to-digital conversion, leakage power consumption, low-power electronics, medical implant devices, successive approximation. I. INTRODUCTION EDICAL implant devices, such as pacemakers and implantable cardiac defibrillators, target increasingly advanced signal acquisition and signal processing systems.

...Paper accepted for presentation at 2009 IEEE Bucharest Power Tech Conference, June 28th - July 2nd, Bucharest, Romania 1 New participants in SmartGrids and associated challenges in the transition towards the grid of the future P. Favre-Perrod, Member, IEEE, R. Critchley, E. Catz & M. Bazargan electricity networks. Abstract – Different concepts for the long term evolution of electricity networks have been proposed. Visions of large scale, continent-wide interconnections, local scale independent distribution network cells and networks integrating other forms of energy have emerged. The inclusion of new classes of network participants, e.g. prosumers, services providers, transportation applications, regulators and the increase of the number of distributed generators is a common feature of all these frameworks. A series of challenges result from this evolution: the need to coordinate distributed participants, the need to harmonize standards and procedures, as well as the need to overcome a series of obstacles to change. This contribution reviews emerging network concepts and the associated challenges. Series compensation, reconfigurable power electronic systems and wide-scale use of phasor measurement units are early examples for these emerging solutions. Index terms – Power transmission, Power transmission planning II. CONCEPTS FOR FUTURE ELECTRICITY NETWORKS A.

...S. Park and S.-Y. Ohm: New Techniques for Real-Time FAT File System in Mobile Multimedia Devices 1 New Techniques for Real-Time FAT File System in Mobile Multimedia Devices Sunhwa Park and Seong-Young Ohm Abstract — Flash memory has become the most important storage media in the mobile multimedia products such as MP3 players, mobile phones, and digital cameras. Most mobile multimedia devices, however, use one of the conventional FAT file systems slightly modified for flash memory environments. Our analysis shows that theses file systems have some restriction in recording a live multimedia stream stably because they have irregular write response times. In this paper, we have considered the problems of the existing FAT file system and propose two new techniques to solve the problems. The first technique called Sector Reservation method reduces internal overhead effectively. And the other method called ACPA avoids the periodic cluster allocation of the conventional FAT file system and removes the frequent modifications on the file allocation table in the FAT file system. To evaluate our new techniques, we implemented a prototype Real-Time FAT file system on ARM9 board with our two novel techniques. The experimental results show that our system achieves our goal successfully in that its write response times are very deterministic and more uniform1. Index Terms — Flash memory, FAT file system, FTL, Mobile multimedia device. I. INTRODUCTION One of the distinct trends in...
