The AD7785 is a low power, low noise, complete analog front end for high precision measurement applications. The AD7785 contains a low noise 20-bit ?-? ADC with three differential analog inputs. The on-chip, low noise instrumentation amplifier means that signals of small amplitude can be interfaced directly to the ADC. With a gain setting of 64, the rms noise is 40 nV when the update rate equals 4.17 Hz. The device contains a precision low noise, low drift internal band gap reference and can accept an external differential reference. Other on-chip features include programmable excitation current sources, burnout currents, and a bias voltage generator. The bias voltage generator sets the common-mode voltage of a channel to AVDD/2.

Front Light Lezyne’s Micro Drive 600XL provides advanced protection against all the bumps and scrapes of the road with a rugged machined aluminium body. Assimilated cooling fins optimise performance and stop the light from overheating during long runtimes. Cut-outs on each side of the light ensure wide, expansive side vision that is great for clearing intersections and traversing through built-up urban areas where it’s crucial to stay seen from multiple different angles. Rear Light The KTV Drive is compact and lightweight whilst retaining an amplitude of durability from its co-moulded outer shell which protects from the harshest of weather conditions with an IPX7 water rating. A Wide Angle Lens offers over 180-degrees of visibility with up to 10 lumens of bright light output. Light Modes Multiple light modes allow you to seamlessly switch between outputs, subsequent runtimes, in both flashing and constant. To keep you visible to motorists during the day the front light comes with a Day Flash mode. All modes can easily be switched between by pressing down on the power button. Front Light (Micro Drive 600XL) Blast: 400 lumens – 1.40 hours Enduro: 200 lumens – 3.15 hours Economy: 100 lumens – 6.45 hours Femto: 15 lumens – 44 hours Day Flash: 600 lumens – 8 hours Flash One: 75 lumens – 17 hours Flash Two: 75 lumens – 17 hours Pulse: 75 lumens – 14.30 hours Overdrive: 600 lumens – 1 hour Rear Light (KTV Drive) Blast: 10 lumens – 4.30 hours Economy: 3 lumens – 12.30 hours Flash One: 10 lumens – 12.30 hours Flash Two: 5 lumens – 20 hours Pulse: 10 lumens – 7 hours Mounting Swift, easy and secure mounting straps seamlessly mount the Micro Drive and KTV Drive to your bike frame. Versatile the straps work with most bar types – size and shape. Charging Save yourself the hassle of ever having to change your bike light’s batteries again with both lights being USB rechargeable. Each light comes with an integrated USB stick that plugs directly into a USB port for cable-free charging that is super quick.

In this study, a CAD model of Indian male human subject of mass 54 kg and 76 kg has been generated using ellipsoidal and solid model approach. A modal analysis has been performed using FEM on these CAD models to calculate natural frequencies and mode shapes at different natural frequencies. An effect of vibrations of different amplitude and frequencies have been calculated using harmonic response analysis under different damping conditions. The purpose of this study is to find out the natural frequencies and corresponding mode shapes which may be helpful in avoiding resonance that are beneficial in designing products for the day to day life of human use such as lifts, escalators, hand rails etc.

Time-ings and Question-Points
32,90 € *

From the rather original recognition that Aristotle's categories are questions, this essay focuses on issues of the pote (pi ), i.e., the question of the "When", and of chronos ( ni ), the "concept" of time. This "concept" is born from and associated with the question of the "When". It is a hermeneutical and (existential)-ontological dialogue, enabling us to think jointly about the so-called "objectivity" of time and its ontological, phenomenological, and hermeneutical relatedness to ourselves. The APPENDIX is an ontological and existential analysis of the question: "What is man?". It's conclusion: that this question cannot, and indeed must not be given a definition-like answer, filled with information and facts. The "response" - and not "answer" - cor-responding to, can only be authentic and open if it claims that: Man is precisely that being who turns his own existence - in a questioning way, both for himself and "other" people, interrogating himself via his own world - into an event. The human and mode-of-being-like questions about the meaning of Being and about the possibility of "What is man?" actually overlap both in their horizons and in their amplitude and radicality.

Fluid Instabilities in Different Conditions
55,90 € *
ggf. zzgl. Versand

Interfacial fluid instabilities are one of the open challenges to the scientists and researchers of fusion community and Astrophysicists. The most common fluid instabilities are RayleighTaylor (RTI), Richtmyer-Meshkov (RMI), Kelvin-Helmholtz (KHI) according to the name of the discoverers. However, these instabilities arise at the interface of two fluids under different physical conditions. RTI occurs when a density gradient ( ~ ) is subjected to an acceleration by an antiparallel pressure gradient ( ~ P) in the presence of perturbations, i.e., when ~ · ~ P 0. This occurs, for example, when a dense fluid is placed above a less dense fluid in the presence of gravity (or in constant force) and then falls when the interface is perturbed. The RTI develops in three stages, beginning with an exponential growth in which each perturbation mode develops independently and is well described by linear stability theory. When the mode amplitude becomes comparable to its wavelength, nonlinearities cause the growth rate to decline, with bubbles of less dense fluid rising parallel to ( ~ ) and separated by narrower spikes of denser fluid traveling in the opposite direction.

A magnetized adiabati dusty electronegative plasma (DENP) (containing Boltzmann electrons, Boltzmann negative ions, adiabati mobile positive ions, and negatively charged stationary dust) has been finally considered, and obliquely propagating DIA solitary waves, and their multi-dimensional instabilities have been theoretically investigated by the reductive perturbation method, and small-k perturbation expansion technique. The combined effects of ion adiabaticity, external magnetic field (obliqueness), and negatively charged dust on the basic properties (speed, amplitude, width, and instability) of small but finite - amplitude DIA solitary waves, are explicitly examined. It is shown that the instability criterion and the growth rate of the unstable perturbation mode are significantly modified by the external magnetic field, the propagation directions of both the nonlinear waves and their perturbation modes. The implications of our results in space and laboratory dusty plasmas are briefly discussed.

Computational chemistry is used in a number of different ways. One particularly important way is to model a molecular system prior to synthesizing that molecule in the laboratory. A second use of computational chemistry is in understanding a problem more completely. There are some properties of a molecule that can be obtained computationally more easily than by experimental means. There are also insights into molecular bonding, which can be obtained from the results of computations that cannot be obtained from any experimental method. Present work highlights complete normal mode analysis, Phonon dispersion, potential energy distribution(PED) of some substituted polyacetylenes.Considering their potential applications in harmonic generation, amplitude and phase modulation, switching and other optical signal processing devices, nonlinear materials are chosen for study of geometry optimization,electrostatic potential, band gap, interpretation IR and Raman activity, natural bond orbital analysis (NBO) and HOMO-LUMO using density functional theory.
