Wirtinger Gradient Based Optimization for High-Quality Computer Generated Holography
Authors: Chakravarthula Praneeth , Peng Yifan , Kollin Joel , Fuchs Henry , Heide Felix
Published: September 2020

Holography is perhaps the most promising technology to achieve wide field of view compact eye-glasses style near-eye displays. However, the digital hologram computation algorithms are still not perfect and resort to heuristic encoding or iterative methods relying on varying relaxations. In this paper, we deviate from such heuristic solutions to holographic phase retrieval but instead rely on formal optimization that is enabled by complex Wirtinger gradients. We pose the entire hologram computation forward model as a differentiable forward model and formulate a quadratic loss function that is solved via firstorder optimization methods. Using this framework, we achieve holographic reconstructions with an order of magnitude improved image quality, both in simulation and on an experimental prototype.

In particular, we focus on simulating of how 3D images focused at different distances are accommodated by a schematic eye model based on HVS. Our numerical simulation is performed by exploiting the complex wave-field distributed in intraocular lights, to effectively deal with holographic properties. Experimental results verify the feasibility and usefulness of our proposed HVS-based holographic image quality analysis method.

Hard-input FEC evaluation using Markov models for equalization-induced correlated errors in 50G PON
Authors: Mahadevan Amitkumar , van Veen Doutje , Kaneda Noriaki , Duque Alex , de Lind van Wijngaarden Adriaan , Houtsma Vincent
Published: September 2020

Channel measurements for a 50G passive optical network (PON) show a significant amount of intersymbol interference (ISI) due to chromatic dispersion (CD) and the use of low-cost, bandwidth-limited 25 Gbaud class components. The channel characteristics at the input of the forward error correction (FEC) decoder are measured for several receiver equalization schemes, and the error correlation at the output of each equalizer is characterized using a sub-class of a Fritchman’s Markov model. This model is used to generate error sequences that match the observed correlation statistics, and these sequences are then used to evaluate the performance of a candidate low-density parity-check (LDPC) code with lifting factor 256 and hard-input decoding. It is shown that for a bandwidth-limited 50G PON system with 83 ps/nm dispersion, the optical power sensitivity penalty (OPSP) due to a reduction in error correction performance caused by correlated errors is 0.3–0.6 dB. Precoding, i.e., differential encoding of the input data and differential decoding, helps to reduce the OPSP for some equalizers, but the penalty increases for other equalizers. The use of a 256-bit segment-interleaver only marginally improves the decoding performance, whereas bit-interleaving across four codewords reduces the penalty to within 0.05 dB relative to the binary symmetric channel.
Espacios de discapacidad durante la España del tardofranquismo y la transición democrática. La invención del “sujeto discapacitado"
Authors: Cayuela Sánchez Salvador
Published: September 2020

La constitución de los seres humanos en sujetos ético-políticos viene precedida por nuestra inclusión en una comunidad política, por la aprehensión de ciertas formas de entendernos a nosotros mismos, a los demás y al mundo, así como por efecto de relaciones de poder y de saber en los distintos espacios sociales. Bajo esta perspectiva, este artículo busca analizar la conformación de una particular forma de subjetividad en el contexto de la España del tardofranquismo y la transición democrática: el sujeto discapacitado. Para ello, se abordarán varias estrategias de gobierno de la discapacidad en tres espacios de análisis: la familia, la escuela y el hospital. En cada uno de ellos, y desde una aproximación que combina principalmente las perspectivas teóricas de Bourdieu, Foucault y los miembros de la Segunda Escuela de Chicago, se analizará el material recabado en 17 entrevistas en profundidad realizadas a personas con discapacidad física, congénita o adquirida, nacidas entre 1938 y 1962 en distintos lugares de España. Este análisis permite comprender la emergencia de una nueva subjetividad entre las personas con discapacidad física en el periodo y el contexto estudiados, así como presentar algunas resistencias en sus procesos de constitución como sujetos.

The non-Indigenous, mestizo, ejido (communal agricultural land) Tecopatlán is located in the municipality of Autlán de Navarro, Jalisco, in the influence zone of the Sierra de Manantlán Biosphere Reserve (SMBR). The primary purpose of this research was to characterize traditional knowledge of medicinal plants held by residents of Tecopatlán in relationship to the land use patterns of the ejido. We interviewed 34 people, selected by convenience sampling, to identify their knowledge of medicinal plants and the local environment. Informants reported a total of 72 medicinal species, belonging to 45 botanical families, distributed across 67 genera. Of the plants recorded, 55 were exogenous and 19 were native species. Informants were surveyed regarding common ailments and the plants used to treat those ailments. The most common ailments reported include diabetes, coughs, kidney problems, nerves, stomach pain, insomnia, cancer, and stroke. The land use patterns described by community members reveal specific areas of the local environment that have the most commonly used medicinal plants.
Rolling the Dice on Piracy
Authors: Bowes Edward
Published: September 2020

Through a single case study utilising archival evidence and a digital artefact review, this research investigates the publisher Wizard of the Coast’s responses to digital piracy via changes to their business model and digital strategy. In response to the loss of revenue via illegally circulated PDF’s of their core content for the roleplaying game system Dungeons and Dragons, Wizard of the Coast stopped the sale of all forms of digital content—restricting the Dungeons and Dragons product to physical copies only. Comparative sales analysis of two editions of Dungeons and Dragons and their competitor Pathfinder, showcases a strong correlation between unrestricted availability of online content and improved sales performance. A further comparison of Wizard of the Coast’s recent digital content platform for Dungeons and Dragons analyses the factors in presenting digital content necessary to encourage a “willingness to pay” in the selected audiences. A combination of a complete content catalogue, personalisation and community features, access to free content samples or tiers, and the continued improvement in service quality are all identified in Wizard of the Coast’s digital platform DnDBeyond, with an increase in physical sales following its debut.

Two-channel time-optimal control of induction heating process with maximum temperature constraint
Authors: Il`ina Natalya A.
Published: September 2020

The formulation and method of solution of the problem of time-optimal control of induction heating process of an unlimited plate with two control actions on the value of internal heat sources with technological constraint in relation to a one-dimensional model of the temperature field are proposed. The problem is solved under the conditions of a given accuracy of uniform approximation of the final temperature distribution over the thickness of the plate to the required. The method of finite integral transformations is used to search for the input-output characteristics of an object with distributed parameters with two control actions. The preliminary parameterization of control actions based on analytical optimality conditions in the form of the Pontryagin maximum principle is used. At the next stage reduction is performed to the problem of semi-infinite optimization, the solution of which is found using the alternance method. The alternance properties of the final resulting temperature state at the end of the optimal process lead to a basic system of relations, which, if there is additional information about the shape of the temperature distribution curve, is reduced to a system of equations that can be solved. An example of solving the problem of time-optimal control of temperature field of an unlimited plate with two offices is carried out in two stages. At first stage the case of induction heating without maximum temperature constraints is considered, at the second stage is carried out on the basis of the results of the first stage to obtain the solution subject to the limitation on the maximum temperature of the heated billet.
Dynamic model of waste heat boiler based on recurrent neural network
Authors: Lusenko Dmitry S. , Danilushkin Ivan A.
Published: September 2020

The work is devoted to the development of a dynamic model of a waste heat boiler based on a recurrent neural network. The developed model can be used to create computer simulators for gas turbine plant operators, technologists and operating personnel. The object of modeling is presented as a complex thermodynamic system. The dynamic processes taking place inside the boiler are non-linear and interconnected. Changes in the technological parameters of the exhaust gases occur in ranges that do not allow to obtain an acceptable quality of the linearized model. Due of the difficulty of creating a mathematical description that takes into account the operation of the installation in different modes, recurrent neural networks were chosen to implement the simulation task. Based on the recurrent neural network, a dynamic model was synthesized that describes the change in the technological parameters of the waste heat boiler in the Power boost, Rated Load, Power reduction operating modes. The model output is the temperature of the network water behind the boiler. The created model takes into account the change in the water flow through the boiler, the change in the inlet water temperature, the increase and decrease in the temperature and pressure of the exhaust gas at the inlet of the waste heat boiler. In the formation of training and test samples for the neural network, archival trends obtained during the operation of the waste heat boiler were used. The article provides experimental data, a description of the stages of the synthesis of a neural network model, structural and graphic schemes, simulation results with explanations.

As far as concerned, this SPA has successfully helped its labors and employees with less obstacles. However, one of the only problems which matters is when SPA receives labor dismissing / laying off report. The SPA considers this problem as aberration, and to resolve it, the SPA holds a bipartite conference with the employers. Unfotunately, the conference fails to resolve. Another solution to resolve this problem is holding another conference, yet this time is a tripartite with Department of Manpower and Transmigration in Semarang, and the latest conference succesfully resolves by giving 70% of basic salary instead of a half, and by giving THR / Tunjangan Hari Raya (Alimony the feast). Keywords :    Labor Union Role;  Labor’s Warfare;  PT.

The aim of this study is to explore the kidney-targeting capability of mesoscale nanoparticles (MNPs)-emodin (Em-MNPs) and its potential antifibrosis in the animal model. First, MNPs and Em-MNPs were synthesized via nanoprecipitation method, and their diameters were both ∼400 nm with the uniform size. The entrapment efficiency of MNPs was 45.1% when adding emodin at the concentration of 12 mg/mL. Moreover, cytotoxicity assay showed that Em-MNPs presented excellent biocompatibility in rat proximal tubular cells. Cellular uptake assay demonstrated that Em-MNPs had high-efficiency uptake, especially in the cytoplasm. Ex vivo organ fluorescence imaging revealed that Em-MNPs possessed specific kidney-targeting ability with relative long retention time in the kidney (∼24 h). In the renal unilateral ureteral obstruction model, Em-MNPs treatment could significantly alleviate kidney tubule injury and reduce extracellular matrix deposition compared with free MNPs. Herein, Em-MNPs with specific kidney-targeting and preferable antifibrosis effects in animal model may pave an avenue for treating renal diseases.

Methanol is an essential chemical building block for the synthesis of numerous industrial products, and has the potential of becoming an alternative fuel. In this study, a simulation of methanol production process was carried out using Aspen Plus software. The process involves two stages, namely syngas production through the dry reforming of methane (DRM) in a reformer reactor and the actual methanol production by the conversion of the syngas obtained. Plug reactor unit operation was employed for the conversion of syngas from the DRM reactor to methanol. Thereafter, the influence of various operating parameters including DRM temperature, plug reactor specification temperature, and pressure effects was studied via the model analysis tool. A rundown of the optimal conditions obtained are DRM temperature of 1050 °C for better conversion of feed and minimal carbon deposit, CH4/CO2 ratio of 0.71, plug reactor constant temperature of 198 °C for optimum methanol yield (4600 kmol) for the given gaseous feed flow rates (5000 kmol/h methane and 7000 kmol/h CO2).
