Channel equalization for MIMO-FBMC systems (2016)

In recent years, it is been a great challenge to have high data transmission rates with additional bandwidth at the same time in wireless communication systems. Multicarrier systems along with MIMO have provided good results in achieving high bandwidth and spectral efficiency. Recently Filter bank multicarrier systems (FBMC) have been implemented and provided better results in terms of spectral shaping of the subcarriers as compared to the traditional orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP). Consequently, the major observable difference between the two approaches is in frequency selectivity. In this research, we will present a modified neural network based algorithm (NN) which is based on mean-squared error (MSE) trained for MIMO-FBMC systems with QAM modulation (QAM). The algorithm presents a per-subchannel adaptive channel equalizer with low complexity. Practical channel information has been used in the simulations. Furthermore, the convergence characteristic curves of NN based equalizer per-subcarrier will be discussed and also how the proposed algorithm will be optimized and evaluated. Moreover, to elaborate equalization concepts more in detail the proposed equalizer will be implemented for classical OFDM-QAM system and results will be compared to the simulations performed for traditional least mean square (LMS) based per-subcarrier channel equalizer.
The process specification system for MMST (1995)

A specification application (SPEC) was created as part of the Microelectronics Manufacturing Science and Technology (MMST) program at Texas Instruments Incorporated. The overall goal of the MMST program was the development of the next generation wafer fabrication system by improving key areas in the fabrication of wafers, including cycle time, cost, and quality. This paper presents the key features of SPEC used to meet the MMST goals. SPEC composes process flow specifications from equipment, step, sequence, and wafer specification hierarchies. Specifications can be reused and can be machine independent. These specifications are integrated into a specification management framework that provides both revision and change notice control. SPEC integrates with other MMST applications to process wafers; including material release into the factory, material movement, machine scheduling, and direct control of equipment-all key features of a paperless factory. During the processing of a wafer, SPEC uses the latest version of a specification. SPEC played a key role in the MMST program especially during the 1000 wafer pilot production run which achieved a single wafer cycle time of less than 72 h.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Uncharted Waters at Ventoso Ship Supply: A Sensory Marketing Dilemma (B). (2018)

This is a three-part, disguised case series. In June 2009, Diana Zanzi was hired by Ventoso Ship Supply, an Italian sailboat manufacturer, to help them understand their boats' puzzling selling patterns. Zanzi was informed that sales rates for two higher-end boat models were especially odd. Despite one's superior technical specifications, speed, amenities, and overall value-for-money, their higher end models were hard to sell. However, a lower-quality boat was sold at an astonishing rate. Existing survey work conducted by the company only served to confirm the rational assumption that customers generally preferred more technically advanced sailboats; as such, the survey would not solve the mystery. Tasked with solving this mystery, Zanzi was given the contact information for Ventoso's roster of potential customers and asked to conduct her own interviews to discover what could possibly explain customers' preferences when acquiring sailboats. Zanzi was told that consumers may not be consciously aware of how they choose sailboats, and so she needed to figure out a good method to understand these unconscious preferences. In part A of the series, the reader is faced with the task of designing a test that might reveal buyers' sailing-related thoughts. For instance, what should Zanzi ask consumers to understand their implicit and unconscious perceptions of the ideal sailboat? More importantly, the reader is invited to consider when and why such a tool is needed. In other words, what marketing technique should we use when consumers don't seem to be fully aware of their decision process?

Uncharted Waters at Ventoso Ship Supply: 
A Sensory Marketing Dilemma (A) 
When Diana Zanzi was hired by Ventoso Ship Supply (Ventoso), an Italian sailboat manufacturer, in June 2009 to help it make sense of its boats' mysterious selling patterns, she faced a unique dilemma. Riccardo Rossi, Ventoso's long-standing CEO, presented Zanzi with data on Ventoso's sailboats' recent sales performance. However, this data raised more questions than answers for Zanzi. In particular, there were two higher-end cruising boats, the Bella 55 and the Volo 155, that defied sales expectations. 
Despite the Volo 155's superior technical specifications, speed capabilities, modern amenities, and overall better value-for-money, the boat was hard to sell, while the Bella 55 sold at an astonishing rate. Both boats were sold from the same Ventoso sales centers, and neither model benefitted from any specific targeted marketing campaign for it. (See Exhibit1 for the technical specifications and sales records of the two boats; see Exhibits2a and 2b for data on the company's sales patterns in relation to boat quality and price.)

An Energy Minimization Approach to Automatic Traffic Camera Calibration (2013)

We present a method for automatic calibration of traffic cameras. The problem is formulated as one of energy minimization in reduced road-parameter space, from which internal and external camera parameters are determined. Our approach combines bottom-up processing of a video to find a vanishing point, lines in the background, and a directed activity map, along with top-down processing to fit a road model to these detected features using Markov chain Monte Carlo (MCMC). Enhanced autocorrelation along the dashed lines is used in conjunction with a best-fit road model to find road-to-image parameters. To maximize both robustness to noise and flexibility (e.g., to handle cases in which the camera is looking straight down the road), a single-vanishing-point length-based approach (VWL, according to the taxonomy in the work of Kanhere and Birchfield) is used. On a large number of data sets exhibiting a wide variety of conditions (including distractions such as bridges and on/off-ramps), our approach performs well, achieving less than 10% error in measuring test lengths in all cases.
Enhancing Vendor Managed Inventory Supply Chain Operations Using Blockchain Smart Contracts (2020)

Supply chain networks have grown in complexity and size due to increased globalization leading to a variety of challenges and opportunities for improvement. Optimizing inventory levels and adjusting replenishment policies have significant effects on the operational performance and profitability of supply chains. Vendor Managed Inventory (VMI) is a mutually beneficial arrangement between supplier and buyer, where the supplier is responsible for making inventory and replenishment decisions based on buyers' inventory status. Potential benefits of VMI include reducing inventories, enabling information sharing, eliminating safety stock, and reducing purchasing related costs across the supply chain. In today's supply chains, VMI operations face critical challenges related to data integrity, transparency, traceability, and single point of failure due to its centralized architecture. Blockchain technology is a distributed ledger that ensures a transparent, safe, and secure exchange of data among supply chain stakeholders. The advantages of adopting blockchain technology for VMI operations in a supply chain include decentralized control, security, traceability, and auditable time-stamped transactions. In this paper, we present a blockchain-based approach using smart contracts to transform VMI supply chain operations. We propose a generic framework using Ethereum smart contracts and decentralized storage systems to automate the processes and information exchange and detailed algorithms that capture the interactions among supply chain stakeholders. The smart contract code was developed and tested in Remix environment. We present cost and security analysis incurred by the stakeholders in the supply chain. Adopting a blockchain-based solution to VMI operations in supply chains is economically viable and provides a streamlined, secure, trusted, and transparent mode of communication among various stakeholders.
Determination of Mercury in Geological Materials by Continuous-Flow, Cold-Vapor, Atomic Absorption Spectrophotometry (1987)

Abstract To determine mercury in geological materials, samples are digested with nitric acid and sodium dichromate in a closed teflon vessel. After bringing to a constant weight, the digest is mixed with air and a sodium chloride-hydroxylamine hydrochloride-sulfuric acid solution and then Hg(II) is reduced to Hg with stannous chloride in a continuous flow manifold. The mercury vapor is then separated and measured using cold vapor atomic absorption spectrophotometry (CV-AAS). For a 100 mg sample the limit of detection is 20 parts per billion (ppb) Hg in sample. To obtain a 1% absorption signal, the described method requires 0.21 ppb Hg solution (equal to 16 ppb in sample). Precision is acceptable at less than 1.2% RSD for a 10 ppb Hg aqueous standard. Accuracy is demonstrated by the results of the analysis of standard reference materials. Several elements do interfere but the effect is minimal because either the digestion procedure does not dissolve them (e.g., Au or Pt) or the; are normally of low abundance (e.g., Se or Te).

Reversine Increases the Plasticity of Lineage-committed Cells toward Neuroectodermal Lineage (2008)

Functional dedifferentiation of lineage-committed cells toward pluripotency may have a great potential in regenerative medicine. Reversine has been shown to induce dedifferentiation of multiple terminally differentiated mesodermal origin cells, which are capable of being directed to differentiate into other cell types within mesodermal lineages. However, the possibilities of these cells to give rise to other lineages have not been examined. Here we show that large scale gene expression profiling of reversine-treated C2C12 myoblasts identifies a subset of up-regulated genes involved in specification of neuroectodermal as well as mesodermal lineages. Reversine treatment leads to up-regulation of priming genes of neuroectodermal lineages, such as Ngn2, Nts, Irx3, Pax7, Hes1, and Hes6, through active histone modifications in the promoter regions of these genes. Additionally, reversine increases the expression of markers for other cell types of mesodermal lineages, Ogn and apoE, via inducing active histone modifications, while down-regulating the myogenic basic helix-loop-helix factor, MyoD, via repressive histone modifications. Consistent with up-regulation of these genes, reversine-treated C2C12 myoblasts redifferentiate into neural as well as mesodermal lineages, under appropriate stimuli. Taken together, these results indicate that reversine induces a multipotency of C2C12 myoblasts via inducing a specific combination of active histone modifications. Collectively, our findings provide a mechanistic rationale for the application of reversine to dedifferentiation of somatic cells.

Structural water as an essential comonomer in supramolecular polymerization (2017)

Although the concept of structural water that is bound inside hydrophobic pockets and helps to stabilize protein structures is well established, water has rarely found a similar role in supramolecular polymers. Water is often used as a solvent for supramolecular polymerization, however without taking the role of a comonomer for the supramolecular polymer structure. We report a low-molecular weight monomer whose supramolecular polymerization is triggered by the incorporation of water. The presence of water molecules as comonomers is essential to the polymerization process. The supramolecular polymeric material exhibits strong adhesion to surfaces, such as glass and paper. It can be used as a water-activated glue, which can be released at higher temperatures and reused many times without losing its performance.

Lid-Integral Cold-Plate Topology: Integration, Performance, and Reliability (2016)

We demonstrate the lid-integral silicon cold-plate topology as a way to bring liquid cooling closer to the heat source integrated circuit (IC). It allows us to eliminate one thermal interface material (TIM2), to establish and improve TIM1 during packaging, to use wafer-level processes, and to ease integration in first-level packaging. We describe the integration and analyze the reliability aspects of this package using modeling and test vehicles. To compare the impact of geometry, materials, and mechanical coupling on warpage, strains, and stresses, we simulate finite element models of five different topologies on an organic land-grid array (LGA) carrier. We measure the thermal performance in terms of thermal resistance from cold-plate base to inlet liquid and obtain 15 mm2 K/W at 30 kPa pressure drop across the package. We build two different topologies using silicon cold-plates and injection-molded lids. Gasket-attached cold-plates pass an 800 kPa pressure test, and direct-attached cold-plates fracture in the cold-plate. The results advise to use a compliant layer between cold-plate and manifold lid and promise a uniformly thick TIM1 layer in the Si–Si matched topology. The work shows the feasibility of composite lids with integrated silicon cold-plates in high heat flux applications.

Spatial distribution of the luminescence in GaN thin films (1996)

The spatial dependence of the luminescence intensities at the band edge (364 nm) and at the ‘‘yellow’’ defect-band (centered at 560 nm) regions for epitaxial GaN films have been studied using cathodoluminescence microscopy at room temperature. The films were grown by metalorganic chemical vapor deposition on (0001) sapphire substrates and were not intentionally doped. Significant nonuniformities in the band-to-band and in the yellow band emissions were observed. Yellow luminescence in small crystallites appears to originate from extended defects inside the grains and at low-angle grain boundaries. The size of band-to-band emission sites correlates with low-angle grain sizes observed by transmission electron microscopy.

The integrated model of airline fleet assignment and aircraft routing based on flight cycle (2010)

The tactical planning process of an airline is typically divided into several stages, in which, fleeting, aircraft routing, and crew pairing are three main parts. In the process, the output of fleeting becomes the input to aircraft routing, the output to aircraft routing is in turn the part of the input to crew pairing. Due to this decomposition, the resulting solution is often suboptimal. In this paper, we propose a model that integrates the fleeting and aircraft routing stages in the making-decision process, and guarantees feasible aircraft routings, but neglects the constraints pertain to airport facilities and crew schedule rules. We design a solution methodology to solve the model, which is based on the Branching strategy. The model is test on a computational experiment, the result indicates that the application of the integrated model can improve the aircraft utilization effectively.
