One of the obstacles to achieving high recording density in hard disk drives (HDDs) is servo performance limitation.As HDD is a mass produced commodity, the challenge is not only achieving high performance for nominal models but with all the uncertainties and variations in HDD models for thousands of HDDs in a batch of production line. This paper presents the implementation results of a novel t...

In-vehicle technologies (IVTs) create additional tasks for the driver. To the extent that these devices degrade driving performance, there will be safety concerns. This study examines the effects of display clutter from overlay, display separation, and modality on driving and IVT task performance. In a fixed-base simulator, 22 drivers drove different routes and responded to infrequent, unexpect...

Halloysite nanotube (HNT)-based supramolecular complexes are synthesized and evaluated with respect to their cytotoxicity and effects on cellular structures. As HNTs are water-insoluble, DNA is applied for wrapping the surface of HNTs to enhance their water-dispersibility. To investigate the potential of DNA-wrapped HNTs (HD) as a promising drug delivery carrier, doxorubicin (DOX) is introduced...

A new combined equalization/synchronization technique, known as SC-PMC (self-convoluting partial mass center), for use in partial response systems is presented. The work is significant as the new technique utilizes a single tap delay line LMS (Least Mean Square) filter for performing the task of equalization and synchronization for the partial response transceiver. Conventional partial response...

El análisis de Mercurio (Hg) en sedimentos la bahía Cartagena especialmente las muestras tomadas un puerto carga, demostró que hay presencia este metal, el cual es catalogado como nocivo para los seres vivos. Los valores oscilaron entre 109 y 288 µg/Kg peso seco, con valor mediana 169 una media 183.33 ± 55.41 µg/Kg. Por otro lado, se realizó determinación Hidrocarburos Disueltos Dispersos (HDD)...

Local feature extraction remains an active research area due to the advances in fields such as SLAM, 3D reconstructions, or AR applications. The success these applications relies on performance of detector, descriptor, and its matching process. While trend detector-descriptor interaction most methods is based unifying two into a single network, we propose alternative approach that treats both c...

This research combined the Taguchi method and artificial intelligence methods, used them as the prediction tool in wire bond designing parameters for an Ultra-Thin CSP package, and then constructed a set of the optimal parameter analysis flow and steps. This paper employed desirability function to integrate two quality characteristics (loop height and wire pull strength) into a single quality i...

In this study, an experimental approach is established to assess the performance of different beams coupled to a Voice Coil Motor (VCM) with the aim to maximize mechanically the energy harvesting in the inductive transducer that is included on it. The VCM is extracted from a recycled hard disk drive (HDD) and it is adapted for carrying out experimental tests of energy harvesting. Two individual...

In our present work, magnetic cobalt ferrite (CoFe2O4) nanoparticles have been successfully synthesised by thermal decomposition of Fe(III) and Co(II) acetylacetonate compounds in organic solvents in the presence of oleic acid (OA)/ oleylamine (OLA) as surfactants and 1,2-hexadecanediol (HDD) or octadecanol (OCD-ol) as an accelerating agent. As a result, CoFe2O4 nanoparticles of different shape...
