Digital Calculation Of Frequency Of Periodical Signal (Sinusoidal And Triangular, Tarak Benslimane, Boukhemis Chetate

Boukhemis Chetate

– In This paper, a method of digital calculation of frequency of periodical signal (sinusoidal, triangular and square signals) is proposed. This method is based on calculation of time between two successive peaks of the rectified signal which constitutes it’s half period. This method allows the measurement of AC current and voltage of AC electrical network. To apply this method, it is necessary to have current and voltage sensors, analogue/ digital converter (ADC) and a processor. A software C++ based program is developed which can be implemented using appropriate processor. In the end are presented the digital simulation results.

Citizen Based Public Health Surveillance, Monitoring And Post-Event Assessments, Thomas Lyons Carr Iii

Thomas Lyons (Thom) Carr III Appl.Sc., CEM

When a sudden on-set emergency or disaster affects a region or the whole country, communities and neighborhoods should plan for the possibility that emergency and other civic services will be disrupted and unavailable (District of Columbia 2003a, 2003b, 2004; Doyle 2004; Siskiyou County Public Health/NorCalBT.com 2004). The event may be severe enough that the routine public health surveillance and monitoring system will be disrupted or the system will not be able to provide data quickly enough to support state and local decisionmaking. A temporary post-disaster system should be planned for and implemented. The epidemiologist supporting the local decision makers must …

A Minimal Model For The Helix-Coil Transition Of Worm-Like Polymers, Gustavo Carri

Gustavo A. Carri

We present a geometric approach to the simulation of the Helix-Coil transition in wormlike polymers. In our model, the polymer is treated as a Freely Rotating Chain with hard-core repulsion between beads. The conformational state (helix or coil) of each bead is determined by the value of its torsion. If the difference between the torsion of a bead and the one of the perfect helix is less than a cutoff value, then the bead is part of a helical domain and carries a negative energy, otherwise it is part of a random coil. We have simulated these concepts using the …

Keyboards For Inputting Japanese Language: A Study Based On Us Patents, Umakant Mishra

Umakant Mishra

The most commonly used Japanese alphabets are Kanji, Hiragana and Katakana. The Kanji alphabet includes pictographs or ideographic characters that were adopted from the Chinese alphabet. Hiragana is used to spell words of Japanese origin, while Katakana is used to spell words of western or other foreign origin.

Two methods are commonly used to input Japanese to the computer. One, the “kana input method” that uses a keyboard having 46 Japanese iroha (or kana) letter keys. The other method is “Roma-ji input method”, where the Japanese letters are composed of English input from a standard QWERTY keyboard. Both the methods …

Mil-Std-188-125-1, High-Altitude Emp Protection For Fixed Ground-Based Facilities

George H Baker

MIL-STD-188-125-1 establishes minimum requirements and design objectives for high-altitude electromagnetic pulse (HEMP) hardening of fixed ground-based facilities that perform critical, time-urgent command, control, communications, computer, and intelligence (C4I) missions. The standard prescribes minimum performance requirements for low-risk protection from mission-aborting damage or upset due to HEMP environments. It also addresses minimum testing requirements for demonstrating that prescribed performance has been achieved and for verifying that the installed protection subsystem provides the operationally required hardness for the completed facility. Covered fixed ground-based facility types include subscriber terminals and data processing centers, transmitting and receiving communications stations, and relay facilities. Use of …

10 Inventions On Reducing Keyboard Size, Umakant Mishra

Umakant Mishra

A conventional computer keyboard consists of as many as 101 keys. The keyboard has several sections, such as text entry section, navigation section, and numeric keypad etc. and each having several keys on the keyboard. The size of the keyboard is a major inconvenience for portable computers, as they cannot be carried easily. Thus there are certain circumstances which compels to reduce the size of a keyboard. Reducing the size of a keyboard leads to several problems. A reduced size keyboard may not contain all the keys available on a full size keyboard; a reduced size keyboard may not be …

What Communities Should Do Pre-Event To Support Public Health Post-Event Assessments, Surveillance And Monitoring, Thomas Lyons Carr Iii

Thomas Lyons (Thom) Carr III Appl.Sc., CEM

[Abstract written March 2008, TLC] Under worst-case planning assumptions used by some major metropolitan areas, a Neighbor-to-Neighbor self-help program model is the primary link between citizens and the professional response personnel of the responsible government agencies.

In the Neighbor-to-Neighbor self-help program model or a Community Emergency Management Plan (CEMP) calls on the citizens in neighborhoods to identify and establish cluster emergency preparedness committees, Cluster Emergency Coordination Centers (CECC) and Community Emergency Response Teams (CERT). Missing from these plans or what is not articulated is how constant Public Health Post-Event Surveillance, Monitoring and Assessments will be done. Given the worst-case planning …

Inkjet Printing Of Viable Mammalian Cells, Tao Xu, Joyce Jin, Cassie Gregory, Jay Hickman, Thomas Boland

Thomas Boland

The purpose of this study was to explore the use of a commercial thermal printer to deposit Chinese Hamster Ovary (CHO) and embryonic motoneuron cells into pre-defined patterns. These experiments were undertaken to verify the biocompatibility of thermal inkjet printing of mammalian cells and the ability to assemble them into viable constructs. Using a modified Hewlett Packard (HP) 550C computer printer and an HP 51626a ink cartridge, CHO cells and rat embryonic motoneurons were suspended separately in a concentrated phosphate buffered saline solution (3 x). The cells were subsequently printed as a kind of "ink" onto several "bio-papers" made from …

Cluster Treatment Of Characteristic Roots, Ctcr, A Unique Methodology For The Complete Robustness Analysis Of Linear Time Invariant Multiple Time Delay Systems Against Delay Uncertainties, Rifat Sipahi

Rifat Sipahi

Today, many high-tech applications such as simultaneous metal machining, neural networks, internet data congestion, population dynamics, chemical processes, formation flight problems, etc., appear in the form of multiple time delay systems (MTDS ). Due to the presence of delays, the stability of the dynamics is under question and needs to be addressed. In the last four decades, the stability analysis of the general class, Linear Time Invariant MTDS (LTI-MTDS), has been one of the challenging problems of the systems and control community, which originates from the complex stability analysis due to their infinite dimensionality. For tackling this, a unique procedure …

Runoff Production In The Upper Rio Chagres Watershed, Panama, Fred Ogden

Fred L. Ogden

Runoff production in tropical watersheds is governed by a wide variety of potential sources and there have been few rigorous studies to date. The 414 km2 upper Río Chagres basin offers a unique opportunity to better understand the runoff production mechanisms in tropical watersheds through data analysis and modeling with rainfall and runoff data. Flow data and tipping bucket rain gage data are available at both the basin outlet (Chico gage) and for an 80.6 km2 internal basin location (Piedras gage). Modeling is performed using the Sacramento Soil Moisture Accounting Model (SAC-SMA), calibrated using data from 2000 and verified using …

Modular Teaching And Product Design Projects In Capstone Design, Yasar Demirel

YASAR DEMIREL

Some latest employment surveys show that chemical engineers are working in more and more diverse industries. For example, some of them design and manufacture specialty products, and need to understand property-structure relationships using chemistry, biology, and physics. Therefore, modular teaching with specialty product design projects would be useful, and should be integrated into the capstone design. Modular teaching can provide a means of responding to diverse and fast changing course contents and learning/teaching objectives. Product design projects come in various categories, such as separations, heat and mass transfer, kinetics, thermodynamics, or biotechnology, and incorporate DMAIC (Define, Measure, Analyze, Improve, Control) …

Stability Of Transport And Rate Processes, Yasar Demirel

YASAR DEMIREL

About fifty years ago, the Turing instability demonstrated that even simple reaction-diffusion systems might lead to spatial order and differentiation, while the Rayleigh-Bénard instability showed that the maintenance of nonequilibrium might be the source of order in fluids subjected to a thermodynamic force above a critical value. Therefore, distance from global equilibrium in the form of magnitude of a thermodynamic force emerges as another constraint of stability; some systems may enhance perturbations, and evolve to highly organized states called the dissipative structures after a critical distance on the thermodynamic branch. Although the kinetics and transport coefficients represent short-range interactions, chemical …
