The Impact Of The Implementation Of Temporary Import Procedure On Electronic Products: Input--Output Analysis, Dedi Abdul Hadi, Toru Matsumoto

Journal of Environmental Science and Sustainable Development

Currently, imported electronic products enter the Indonesian market using general import procedures, where the importer has to pay the import duty and taxes in full rate. In the absence of proper recycling systems, the electronic products that have reached their end of life and those are no longer used, end up in the landfills. Some researchers found hazardous materials inside the electronic products that could contaminate water, soil and air. Therefore, another strategy is needed to avoid negative effects on the environment. The Temporary import policy is one of the import procedures under Customs administration control, which states that goods …

Accounting For The Environmental Impacts Associated With Residual Products In A Comparative Life Cycle Assessment Of Systems With Multiple Products, Yasuhiro Fukushima, Satoshi Ohara

Journal of Environmental Science and Sustainable Development

In many production systems, multiple products are interactively produced. Therefore, an innovative technology that leads to changes in parts of such systems may influence both the unit environmental impacts associated with the products, and the productivity of multiple products. To compare alternative technologies on a common basis, we often account for the avoided or supplemented emissions associated with the residual (i.e. surplus and supplemented) products produced from within the considered system boundary. In this study, using an example of an innovative technology envisioned for use in sugar mills, we first demonstrate how comparisons can be made when the systems vary …

Determination Of The Influence Of Spin-Off Roundess On The Value Of Spinning Yarn During Spinning, S.X Babadjanov, F.F Isxakova

Central Asian Problems of Modern Science and Education

The article presents the results of studies of the influence of the unevenness of roundness of the spinning rings on the tension of the yarn produced. It is also noted that if the shape of the ring is distorted, then the slider's trajectory is not a circle, but some closed curve that follows the shape of the ring, while, in general, at each subsequent time, the slider moves along a curve with a different curvature radius. The design scheme and the method for calculating the tension of the yarn from the profile of the ring are given.

Nonparametric Collective Spectral Density Estimation With An Application To Clustering The Brain Signals, Mehdi Maadooliat, Ying Sun, Tianbo Chen

Mathematics, Statistics and Computer Science Faculty Research and Publications

In this paper, we develop a method for the simultaneous estimation of spectral density functions (SDFs) for a collection of stationary time series that share some common features. Due to the similarities among the SDFs, the log‐SDF can be represented using a common set of basis functions. The basis shared by the collection of the log‐SDFs is estimated as a low‐dimensional manifold of a large space spanned by a prespecified rich basis. A collective estimation approach pools information and borrows strength across the SDFs to achieve better estimation efficiency. Moreover, each estimated spectral density has a concise representation using the …

The Role Of Friction In The Static Equilibrium Of A Fixed Ladder: Theoretical Analysis And Experimental Test, Mark P. Silverman

Faculty Scholarship

In a recent publication the author derived and experimentally tested several theoretical models, distinguished by different boundary conditions at the contacts with horizontal and vertical supports, that predicted the forces of reaction on a fixed (i.e. inextensible) ladder. This problem is statically indeterminate since there are 4 forces of reaction and only 3 equations of static equilibrium. The model that predicted the empirical reactions correctly used a law of static friction to complement the equations of static equilibrium. The present paper examines in greater theoretical and experimental detail the role of friction in accounting for the forces of reaction on …

Evidence For Terahertz Acoustic Phonon Parametric Oscillator Based On Acousto-Optic Degenerate Four-Wave Mixing In A Silicon Doping Superlattice, Thomas E. Wilson

Physics Faculty Research

We report evidence for a 1.0-THz self-starting mirrorless acoustic phonon parametric oscillator (MAPPO) produced from acousto-optic phase-conjugate degenerate four-wave (D4WM) mixing in a THz laser-pumped silicon doping superlattice (DSL). The DSL was grown by molecular beam epitaxy on a (100) boron-doped silicon substrate. A superconducting NbTiN subwavelength grating was used to couple the THz laser radiation into the DSL. Superconducting granular aluminum bolometric detection, coupled with Si:B piezophonon spectroscopy, revealed excitation of THz coherent compressional and shear waves, along the ⟨111⟩ direction only. The Bragg scattering condition for distributed feedback, and the energy conservation requirement for the D4WM process, were …

Decays Of Pentaquarks In Hadrocharmonium And Molecular Scenarios, Michael I. Eides, Victor Yu. Petrov

Physics and Astronomy Faculty Publications

We consider decays of the hidden charm LHCb pentaquarks in the hadrocharmonium and molecular scenarios. In both pictures the LHCb pentaquarks are essentially nonrelativistic bound states. We develop a semirelativistic framework for calculation of the partial decay widths that allows the final particles to be relativistic. Using this approach we calculate the decay widths in the hadrocharmonium and molecular pictures. Molecular hidden charm pentaquarks are constructed as loosely bound states of charmed and anticharmed hadrons. Calculations show that molecular pentaquarks decay predominantly into states with open charm. Strong suppression of the molecular pentaquark decays into states with hidden charm is …

The Pilot Application Of Electrochemical Impedance Spectroscopy On Dynamic Proton Exchange Membrane Fuel Cell, Jian-Wei Guo, Jian-Long Wang

Journal of Electrochemistry

By analyzing Electrochemical Impedance Spectroscopy (EIS) in applications of dynamic proton exchange membrane fuel cell (PEMFC), bottlenecks which restrict EIS tool development have been pointed out in this paper. Though the high-frequency resistance in EIS is largely accepted as cell inner-resistance, this can only be applied for cell with low current. The low-frequency resistance is difficult to be realized due to its relation with mass transfer. Furthermore, the improved Randles equivalent circuits are built up preliminarily, thus, penetrating into studies for mass transfer reaction, cell operation/degeneration, and high temperature fuel cell. Inspiringly, EIS is becoming an analyzing tool for stack …
