Rice crop yield prediction using artificial neural networks (2016)

Rice crop production contributes to the food security of India, more than 40% to overall crop production. Its production is reliant on favorable climatic conditions. Variability from season to season is detrimental to the farmer's income and livelihoods. Improving the ability of farmers to predict crop productivity in under different climatic scenarios, can assist farmers and other stakeholders in making important decisions in terms of agronomy and crop choice. This study aimed to use neural networks to predict rice production yield and investigate the factors affecting the rice crop yield for various districts of Maharashtra state in India. Data were sourced from publicly available Indian Government's records for 27 districts of Maharashtra state, India. The parameters considered for the present study were precipitation, minimum temperature, average temperature, maximum temperature and reference crop evapotranspiration, area, production and yield for the Kharif season (June to November) for the years 1998 to 2002. The dataset was processed using WEKA tool. A Multilayer Perceptron Neural Network was developed. Cross validation method was used to validate the data. The results showed the accuracy of 97.5% with a sensitivity of 96.3 and specificity of 98.1. Further, mean absolute error, root mean squared error, relative absolute error and root relative squared error were calculated for the present study. The study dataset was also executed using Knowledge Flow of the WEKA tool. The performance of the classifier is visually summarized using ROC curve.
Microsystems for medical applications (2002)

The different 3D interconnection techniques have been initially applied to memories for a couple of main reasons market and easiness. With the development of a 3D technique from 1988, first at THOMSON-CSF and after at 3D PLUS, other criteria have been taken in account: stacking of the heterogeneous components, civilian applications which could be ruggedized later, and very low cost compatible with communication, automotive and medical applications. To allow this, each of the six operations of the flow chart are derived from large scale manufacturing in connected domains: devices are mounted into foils, taken from the smart cards manufacturing "Reel to Reel process" developed by GEMPLUS, same plastic moulding than the encapsulation technique of dice into plastic packages, plating identical to the metallized holes process in the printed circuit board industry, and laser etching by the mean of a YAG marking laser.
High performance Sockets over kernel level virtual interface architecture (2005)

The Sockets application programming interface is the de facto standard in network programming. Sockets emulation over high performance networks has being pursued by many researchers. Most projects in this area favor user level communication, but this approach has resulted in some compatibility problems. In this paper, after the reexamination of the tradeoff between user level and kernel level communication, the design and implementation of Sockvia are discussed which is a kernel level Sockets emulation system based on virtual interface architecture. Sockvia emulates Sockets streaming semantics and achieves full compatibility with Sockets over TCP/IP. Through performance optimization methods such as lightweight flow control and private buffer, the performance of Sockvia is very attractive compared with that of Sockets over GM-IP or SGM. The half round-trip latency of Sockvia is below 12 us and the peak bandwidth is over 240 MBytes. The results of real-world application tests are also presented.
Generalized gradient vector flow external forces for active contours (1998)

Active contours, or snakes, are used extensively in computer vision and image processing applications, particularly to locate object boundaries. A new type of external force for active contours, called gradient vector flow (GVF) was introduced recently to address problems associated with initialization and poor convergence to boundary concavities. GVF is computed as a diffusion of the gradient vectors of a gray-level or binary edge map derived from the image. In this paper, we generalize the GVF formulation to include two spatially varying weighting functions. This improves active contour convergence to long, thin boundary indentations, while maintaining other desirable properties of GVF, such as an extended capture range. The original GVF is a special case of this new generalized GVF (GGVF) model. An error analysis for active contour results on simulated test images is also presented. Aktive Umrisse, oder Schlangen, werden vielfach in Computervision- und Bildverarbeitungs-Anwendungen benutzt, um insbesondere Objektgrenzen zu lokalisieren. Ein neuer Typ äußerer Kräfte für aktive Umrisse, Gradient Vector Flow (GVF) genannt, wurde kürzlich eingeführt, um Probleme anzusprechen, die mit Initialisierung und schlechter Konvergenz zu Grenzkonkavitäten zusammenhängen. GVF wird als eine Diffusion des Gradientenvektors einer Graustufen- oder `Binary Edge'-Karte berechnet, die aus dem Bild gewonnen werden. In diesem Artikel verallgemeinern wir die GVF Formulierung, so daß zwei räumlich variierende Gewichtsfunktionen engneschlossen werden. Dies verbessert die Konvergenz aktiver Umrisse zu langen, dünnen Grenzmarkierungen, während andere wünschenswerte Eigenschaften des GVF, wie erweiterter Einfangbereich, erhalten bleiben. Das ursprüngliche GVF ist ein Spezialfall dieses neuen verallgemeinerten GVF (GGVF) Modells. Eins Fehleranalyse von Ergebnissen aktiver Umrisse mit simulierten Testbildern wird ebenfalls präsentiert. Les contours actifs, ou serpents (snakes), sont utilisés intensivement en vision par ordinateur et pour les applications de traitement d'images, particulièrement pour localiser les contours d'objects. Un nouveau type de force externe pour les contours actifs, appelè flux de vecteurs gradients (FVG) a été introduit récemment pour traiter les problémes associés à l'initialisation et la faible convergence vers des concavités dans les contours. Le FVG est calculé comme une diffusion des vecteurs gradients d'une carte des contours d'une image en niveaux de gris ou binaire. Dans cet article, nous généralisons la formulation du FVG pour y inclure deux fonctions de poids à variation spatiale. Ceci améliore la convergence des contours actifs vers les indentations de contours fines et longues, tout en maintenant les autres propriétés intéressantes des FVG comme la plage de capture étendue. Les FVG originaux sont un cas particulier des modèles de FVG généralisés. Une analyse de l'erreur des résultats de contours actifs sur des images de test synthétiques est aussi présentée.

Throughput optimization of general non-linear computations (1999)

This paper addresses an optimal technique for throughput optimization of general non-linear data flow computations using a set of transformations. Throughput is widely recognized as the most important design metric of the modern DSP and communication applications. Numerous approaches have been proposed for throughput optimization, but most were restricted to limited classes of computations. They have limited effectiveness when applied to large complex non-linear DSP and communication computations. The new technique is used as an optimization engine in a divide-and-conquer global approach for throughput optimization. We demonstrate the effectiveness of the new technique on numerous real-life non-linear designs.

Epitaxial growth and properties of YBa2Cu3O7−<i>y</i>/LaSrGaO4/YBa2Cu3O7−<i>y</i> trilayer structures (1994)

We report the successful synthesis of insulating LaSrGaO4(LSGO) thin films and YBa2Cu3O7−y(YBCO)/LSGO heteroepitaxial multilayer structures using a pulsed laser deposition technique. SrTiO3(STO)(100) was used as a substrate. The formation of highly c-axis oriented YBCO/LSGO/YBCO trilayer structures is demonstrated. Epitaxial YBCO films on LSGO//STO and LSGO/YBCO//STO have a zero resistance temperature of 88.5 and 88.3 K, respectively. Sandwich-type YBCO/LSGO/YBCO junctions were produced by a suitable patterning technique. The observed (dI/dV)-V characteristics exhibit a clear single gap structure (width ∼26 meV) at temperatures below 30 K.
Cerebral complications of murine monoclonal CD3 antibody (OKT3): CT and MR findings. (1998)

Treatment of acute renal allograft rejection with mouse monoclonal antibody (OKT3) is associated with systemic and neurologic side effects. We describe cerebral abnormalities in a 13-year-old boy with steroid-resistant renal allograft rejection. After treatment with OKT3, an acute neurologic syndrome developed, including seizures, lethargy, and decreased mental function. CT and MR imaging revealed confluent cerebral lesions at the corticomedullary junction. Contrast-enhanced MR images showed patchy enhancement, indicating blood-brain barrier dysfunction. The diagnosis of OKT3-induced encephalopathy with cerebral edema and capillary leak syndrome was made. Although CT and MR findings are nonspecific, neuroradiologists should be aware of this condition in transplant patients treated with OKT3.

Cortical spreading depression and peri-infarct depolarization in acutely injured human cerebral cortex (2005)

Electrocorticographic (ECoG) activity was recorded for up to 129 h from 12 acutely brain-injured human patients using six platinum electrodes placed near foci of damaged cortical tissue. The method probes ECoG activity in the immediate vicinity of the injured cortex and in adjacent supposedly healthy tissue. Six out of twelve patients displayed a total of 73 spontaneous episodes of spreading depression of the ECoG. Of the remaining 6 patients 1 displayed an episode of synchronous depression of ECoG during surgery. Using the same electrodes we also measured the slow potential changes (SPC) (0.005-0.05 Hz) to test the hypothesis that the ECoG depressions were identical to Leao's cortical spreading depression (CSD), and to be able to record peri-infarct depolarisations (PIDs) in electrically 'silent' cortical tissue. Changes in the SPC indicate depolarization of brain tissue. For the analysis, the SPCs were enhanced by calculating the time integral of the ECoG signal. Spreading ECoG depressions were accompanied at every single recording site by stereotyped SPCs, which spread across the cortical mantle at 3.3 (0.41-10) mm/min (median, range), i.e. at the same speed of spread as the depression of the ECoG activity. The amplitude of the SPCs was 0.06-3 mV. In 4 out of 6 patients the ECoG recovered spontaneously. In 2 patients we subsequently recorded recurrent SPCs, but without recovery of the initial ECoG background activity until 2-5 h later. This represents the first direct recording of PIDs in acutely injured human brain. Evidence from this and our previous study of 14 brain-injured patients suggests that CSDs in acute brain disorders occur at higher incidence in patients <30 years (83%) than above (33%). CSD was recorded in 4 out of 5 traumatic brain injury patients, and in 2 out of 7 patients with spontaneous haemorrhages. We conclude that the spreading ECoG depressions recorded in patients are identical to CSDs recorded in animal experiments. We furthermore provide direct electrophysiological evidence for the existence of PIDs and hence a penumbra in the human brain. We hypothesize that the depolarization events might contribute to tissue damage in acute disorders in the human brain.
Oil Recovery Strategies for Thin Heavy Oil Reservoirs (2016)

Up to 80% of heavy oil reservoirs in Western Canada are less than 5 m thick and as yet the only economic processes are cold production ones which realize recovery factors between 5% and 15%. This implies that >85% of the oil remains in the ground after the process becomes uneconomic to continue operation. At this time, no thermal processes exist that are economic. In the research documented in this thesis, reservoir simulation was used to guide the design of recovery processes for unexploited and post-CHOPS thin heavy oil reservoirs. The results suggest that the economic and environmental performance of the oil recovery processes for thin heavy oil reservoirs can be significantly improved through selection of injectants and operating parameters.

Sensing schemes of sense amplifier for single-ended SRAM (2017)

Background/Objective: The memory system occupy a significantly larger area of the SoCs (System on Chip) and it also contributes heavily to the increasing power consumption. The major part of the power consumption is due to the peripheral circuits of the memory systems, with the sense amplifier playing a dominant role, while the memory is accessed for the reading operation. This paper presents a modification of the conventional 6T SRAM cell into the 8T SRAM (Static Random Access Memory) cell memory architecture, focusing on enhancing the writing and reading stability of the memory cell with an additional advantage of providing a separate path for reading the data. Statistical Analysis/Method: To enhance the sensing performance, various sensing schemes such as the domino sensing scheme, AC Coupled sensing scheme and Switching pMOS sense amplifier have been employed. The above mentioned sensing schemes use single bit line for sensing the data. These single ended sensing schemes are implemented and simulated on industry standard Cadence EDA tool using 45nm technology. These are employed for sensing the data from the SRAM banks comprising 8T SRAM cells. Findings: The simulation results show that the power consumption during sensing operation is reduced as compared to traditional sense amplifier due to the advantage of single ended bit line sensing. Conclusion: The investigation and comparison among the three single ended sensing schemes reveals that the switching pMOS sense amplifier exhibits better performance with considerable amount of reduction in sensing power.
Cooperative end-to-end traffic redundancy elimination for reducing cloud bandwidth cost (2012)

The pay-as-you-go service model impels cloud customers to reduce the usage cost of bandwidth. Traffic Redundancy Elimination (TRE) has been shown to be an effective solution for reducing bandwidth costs, and has recently captured significant attention in the cloud environment. By studying the TRE techniques with a trace driven approach, we found that solely using either sender-based TRE or receiver-based TRE cannot simultaneously capture traffic redundancy in both short-term (time span of seconds) and long-term (time span of hours or days) data redundancy, which concurrently appear in the traffic. Additionally, the TRE efficiency of existing receiver-based TRE solution is susceptible to data changes compared to historical data in the cache. In this paper, we propose a sender and receiver Cooperative end-to-end TRE solution (CoRE) for efficiently identifying and removing both short-term and long-term redundancy. Through a two-layer redundancy detection design and one single pass algorithm for chunking and fingerprinting, CoRE efficiently carries out cooperative operations between the sender and the receiver. By extensive evaluation with several real traces, we show that CoRE is able to identify both short-term and longterm redundancy with low additional cost, while ensuring TRE efficiency from data changes.
Maximizing the impact of microphysiological systems with <i>in vitro</i>–<i>in vivo</i> translation (2018)

Microphysiological systems (MPS) hold promise for improving therapeutic drug approval rates by providing more physiological, human-based, in vitro assays for preclinical drug development activities compared to traditional in vitro and animal models. Here, we first summarize why MPSs are needed in pharmaceutical development, and examine how MPS technologies can be utilized to improve preclinical efforts. We then provide the perspective that the full impact of MPS technologies will be realized only when robust approaches for in vitro-in vivo (MPS-to-human) translation are developed and utilized, and explain how the burgeoning field of quantitative systems pharmacology (QSP) can fill that need.

Model-Based Range Extension Control System for Electric Vehicles With Front and Rear Driving–Braking Force Distributions (2015)

This paper proposes a model-based range extension control system for electric vehicles. The proposed system optimizes the front and rear driving-braking force distributions by considering the slip ratio of the wheels and the motor loss. The optimal distribution depends solely on vehicle acceleration and velocity. Therefore, this system is effective not only at constant speeds but also in acceleration and deceleration modes. Bench tests were conducted for more precise evaluation and to realize experimental results with high reproducibility. The effectiveness of the proposed system was verified through field and bench tests.

CCR7 Expression and Intratumoral FOXP3+ Regulatory T Cells are Correlated with Overall Survival and Lymph Node Metastasis in Gastric Cancer (2013)

The aim of this study was to investigate the prognostic value of chemokine receptor CCR7 expression and intratumoral FOXP3(+) regulatory T cells (Tregs) in gastric cancer. CCR7(+) tumor cells and FOXP3(+) Tregs were assessed by immunohistochemistry in tissue microarrays containing gastric cancer from 133 patients. Prognostic effects of low or high CCR7 and FOXP3 expression were evaluated by Cox regression and Kaplan-Meier analysis, as well as the correlation between CCR7 positive score and intratumoral FOXP3(+) cell number in a longitudinal assessment. The analysis showed that the high expression levels of CCR7 and FOXP3 were detected in 69.9% and 65.4% of cases, respectively. High CCR7 expression in gastric cancer cells was significantly associated with poor overall survival (OS) (P = 0.010) and lymph node metastasis (P = 0.009), and was an independent factor for worse OS (P = 0.023) by multivariate analysis. High numbers of intratumoral FOXP3(+) Tregs significantly correlated with shorter OS (P = 0.021) and lymph node metastasis (P = 0.024), and was also an independent factor for adverse OS (P = 0.035). Furthermore, there was a significantly positive correlation between CCR7 positive score and intratumoral FOXP3(+) cell number (r = 0.949, P<0.001). These results revealed that CCR7 expression in gastric cancer cells and intratumoral FOXP3(+) Tregs could be considered as a co-indicator of clinical prognosis of gastric cancer.
