Floorplan aware framework for optimal SRAM selection for memory subsystems

Embedded memories are the key contributor to the chip area, dynamic power dissipation and also form a significant part of critical path for high performance advanced SoCs. Therefore, optimal selection of memory instances becomes imperative for SoC designers. While EDA tools have evolved over the past years to optimally select standard logic cells depending on the timing and the power constraints, optimal memory selection is largely a manual process. In this thesis, a framework has been proposed to optimize power, performance, and area (PPA) of a memory subsystem (MSS) by including floorplan dependent delays and power consumption in the interconnects and glue logic in the pre-RTL stage. Considering only memory PPA metrics is not sufficient for optimal memory selection and leads to a suboptimal implementation. It has been observed that physical design parameters such as routing congestion and interconnect delays, have significant impact on the implementation of the MSS and including them into the framework leads to more accurate and optimal results. However, to reduce the run-time of the framework, the top N (user input) memory configurations are pre-selected based on the PPA values of the SRAM instances and then the floorplan related metrics are estimated on the refined results. The framework has the capability to use different estimates, when routing congestion is important (for example, in low cost processes with less number of metal layers). It has been shown that the interconnect delays are reduced by about 68% and dynamic power by 58%, if additional metal layers are available for routing compared to a low cost 6 metal process.
J ul 2 01 7 A 3 D DLM / FD method for simulating the motion of spheres in a bounded shear flow of Oldroyd-B fluids

We present a novel distributed Lagrange multiplier/fictitious domain (DLM/FD) method for simulating fluid-particle interaction in Oldroyd-B fluids under creeping conditions. The results concerning two ball interaction in a three dimensional (3D) bounded shear flow are obtained for Weissenberg numbers up to 1 . The pass and return trajectories of the two ball mass centers are similar to those in a Newtonian fluid; but they lose the symmetry due to the effect of elastic force arising from viscoelastic fluids. A tumbling chain of two balls (a dipole) may occur, depending on the value of the Weissenberg number and the initial vertical displacement of the ball mass center to the middle plane between two walls.
DETERMINATION OF SULFONATION CONDITIONS OF HAB AS A BY-PRODUCT OF LINEAR ALKYLBENZENE PRODUCTION

Heavy alkylated benzene (HAB), which is a by-product in linear alkylbenzene (LAB) production by UOP process, is separated by distillation from LAB and consists of a range of components such as polyalkylbenzenes, diphenylalkanes, alkyl tetralins, and alkylindans. The products of sulfonation of HAB or its distillation cuts are of wide industrial applications such as emulsifiers, dispersants in lubricating oils, anionic surfactants, and aqueous phase stable waterflooding. The sulfonation of the HAB mixture using oleum as the sulfonating agent has been carried out and optimum reaction conditions have been defined based on the highest degree of sulfonation. Some light, average, and heavy distillation cuts were then sulfonated under optimum conditions. The degree of sulfonation of the fractions was found to be dependent on the composition of the mixture. 1 HNMR spectroscopy was used to investigate the relationship between the ratio of aliphatic to aromatic protons of the compounds and the trend in sulfonation.
Controlled deterioration to evaluate okra seed vigor

Germination and vigor tests are essential components of seed quality control programs adopted by seed industries. We studied different procedures to perform the controlled deterioration test to identify differences in vigor among okra seed lots. Four seed lots of Colhe Bem cultivar and five seed lots of Santa Cruz 47 cultivar were submitted to the following tests: germination, seedling emergence, controlled deterioration (seeds with moisture contents of 18, 21 and 24% at 45°C for 24 and 48 hours) and moisture content. The controlled deterioration test is efficient to evaluate the physiological potential of okra seeds, and the combination of 24% water, 45°C during 24 hours is recommended.
Monitoring of the BTA Deep Hole Drilling Process Using Residual Control Charts

Deep hole drilling methods are used for producing holes with a high lengthto- diameter ratio, good surface finish and straightness. The process is subject to dynamic disturbances usually classified as either chatter vibration or spiralling. In this work, we propose to monitor the BTA drilling process using control charts to detect chatter as early as possible and to secure production with high quality. These control charts use the residuals obtained from a model which describes the variation in the amplitude of the relevant frequencies of the process. The results showed that chatter is detected and some alarm signals are related to changing physical conditions of the process.
Coronal Faraday rotation of occulted radio signals

Faraday rotation (FR) observations of radio sources near solar conjunction yield information on the coronal magnetic field at heliospheric distances not reached by in situ exploration. Measurements of FR yield the rotation measure (RM), a wavelength independent quantity defined as the integral along the raypath of the product of the electron density times the raypath-parallel component of the magnetic field. Independent observations or models of the coronal electron density are required in order to extract information about the magnetic field. The radio sounding sources can be either artificial (spacecraft) or natural, but they must be at least partially linearly polarized. The most extensive campaign of coronal radio sounding polarization measurements using a spacecraft was the Helios Faraday Rotation Experiment, which was conducted over the duration of the Helios 1 (1974–1984) and Helios 2 (1976–1980) missions. Other coronal FR experiments have been carried out using natural continuum sources recently a.
Isolation and Characterization of a Thermophilic Marine Methanogenic Bacterium, Methanogenium thermophilicum sp. nov.†

A new species of thermophilic marine methanogenic bacteria is described. Cells of this species occurred as irregular cocci, singly or in pairs, and did not possess flagella. Colonies were translucent, beige in color, and circular with entire edges. Either formate or hydrogen and carbon dioxide could serve as a substrate for growth and methane formation, whereas ethanol, methanol, acetate, propionate, and pyruvate could not. The temperature for optimum growth was 55°C, with minimal growth below 37°C and an upper temperature limit of 65°C. The pH for optimum growth was 7.0. Sodium chloride was required for growth; the concentration for optimum growth was 0.20 M. The minimum generation time was 2.5 h. The deoxyribonucleic acid base composition was 59 mol% guanine plus cytosine. The name Methanogenium thermophilicum is proposed for this organism. The type strain is CR-1 (= ATCC 33837 = DSM 2373).
Initial Regional Conditions and Entrepreneurship

This paper analyzes the role of initial conditions for the level of entrepreneurial activity across regions of a post-socialist economy. Thereby, the regional factors that are typically found to affect start-up activity in established market economies are investigated. It is found that the initial industry structure and population density are most important. Entrepreneurial culture is only partially important for general start-up activity, whereas the initial stock of knowledge has no effect on start-up activity. The implications of this paper are that regions with distinct initial conditions have higher startup rates although the level of start-up activity was equal to ―zero‖ at the beginning and that these conditions are a source of persistence in start-up rates.
Cash Mergers and the Volatility Smile

In an empirical study of cash mergers since 1996, we find that the equity options on target firms display a pronounced smile pattern in their implied volatilities which gets more pronounced when the merger success probability gets higher. We propose an arbitrage-free model to analyze option prices for firms undergoing a cash merger attempt. Our formula matches well the observed merger volatility smile. Furthermore, as predicted by the model, we show empirically that the merger volatility smile has a kink at the offer price, and that the magnitude of the kink is proportional to the merger success probability.
The very energetic, broad-lined Type Ic supernova 2010ah (PTF10bzf) in the context of GRB/SNe

SN 2010ah, a very broad-lined Type Ic supernova (SN) discovered by the Palomar Transient Factory, was interesting because of its relatively high luminosity and the high velocity of the absorption lines, which was comparable to that of gamma-ray burst (GRB)/SNe, suggesting a high explosion kinetic energy. However, no GRB was detected in association with the SN. Here, the properties of SN 2010ah are determined with higher accuracy than previous studies through modelling. New Subaru telescope photometry is presented. A bolometric light curve is constructed taking advantage of the spectral similarity with SN 1998bw. Radiation transport tools are used to reproduce the spectra and the light curve. The results thus obtained regarding ejecta mass, composition and kinetic energy are then used to compute a synthetic light curve. This is in reasonable agreement with the early bolometric light curve of SN 2010ah, but a high abundance of 56Ni at high velocity is required to reproduce the early rise, while a dense inner core must be used to reproduce the slow decline at late phases. The high-velocity 56Ni cannot have been located on our line of sight, which may be indirect evidence for an off-axis, aspherical explosion. The main properties of SN 2010ah are: ejected mass Mej ≈ 3 M⊙; kinetic energy Ekin ≈ 1052 erg, M(56Ni) ≈ 0.25 M⊙. The mass located at v ≳ 0.1 c is ∼0.2 M⊙. Although these values, in particular the Ekin, are quite large for a Type Ic SN, they are all smaller (especially Mej) than those typical of GRB/SNe. This confirms the tendency for these quantities to correlate, and suggests that there are minimum requirements for a GRB/SN, which SN 2010ah may not meet although it comes quite close. Depending on whether a neutron star or a black hole was formed following core collapse, SN 2010ah was the explosion of a CO core of ∼5 to 6 M⊙, pointing to a progenitor mass of ∼24–28 M⊙.
Simpler than vacuum: Antiscalar alternatives to black holes

The Janis-Newman-Winicour and Papapetrou metrics represent counterparts to the Schwarzschild black hole with scalar and antiscalar background fields, correspondingly (where "anti" is to be understood as in "anti-de Sitter"). There is also a scalar counterpart (the Krori-Bhattacharjee metric) to the Kerr black hole. Here we study analytical connections between these solutions and obtain the exact rotational generalization of the antiscalar Papapetrou spacetime as a viable alternative to the Kerr black hole. The antiscalar metrics appear to be the simplest ones as they do not reveal event horizons and ergospheres, and they do not involve an extra parameter for scalar charge. Static antiscalar field is thermodynamically stable and self-consistent, but this is not the case for the scalar Janis-Newman-Winicour solution; besides, antiscalar thermodynamics is reducible to black-hole thermodynamics. Lensing, geodetic and Lense-Thirring effects are found to be practically indistinguishable between antiscalar and vacuum solutions in weak fields. Only strong-field observations might provide a test for the existence of antiscalar background. In particular, the antiscalar solution predicts 5% larger shadows of supermassive compact objects, as compared to the vacuum solution. Another measurable aspect is the 6.92% difference in the frequency of the innermost stable circular orbit, characterizing the upper cut-off in the gravitational wave spectrum.
A Data-Driven Exploration of Factors Affecting Student Performance in a Third-Level Institution

This paper describes an application of data mining techniques to the analysis of student academic records, collected at Limerick Institute of Technology, with the goal of acquiring clearer, evidence-based understanding of how a variety factors affect students‟ examination performance. To this end, a comprehensive dataset has been prepared. It has been analysed using a variety of machine learning/data mining techniques, in order to examine it from multiple perspectives. Of the techniques used, Bayesian networks have been found to be best in terms of yielding results that are comprehensible and meaningful. The results of this work provide a useful snapshot of factors affecting performance for the student group analysed, as well as demonstrating a process by which other institutions may analyse their own student groups.
Log-ratio methods in mixture models for compositional data sets

When traditional methods are applied to compositional data misleading and incoherent results could be obtained. Finite mixtures of multivariate distributions are becoming increasingly important nowadays. In this paper, traditional strategies to fit a mixture model into compositional data sets are revisited and the major difficulties are detailed. A new proposal using a mixture of distributions defined on orthonormal log-ratio coordinates is introduced. A real data set analysis is presented to illustrate and compare the different methodologies.
Antiviral property of marine actinomycetes against White Spot Syndrome Virus in penaeid shrimps

Aquaculture farms, particularly in Southeast Asia are facing severe crisis due to increasing incidences of White Spot Syndrome Virus (WSSV). Actinomycetes have provided many important bioactive compounds of high prophylactic and therapeutic value and are continually being screened for new compounds. In this communication, the results of a study made to determine the effectiveness of marine actinomycetes against the white spot disease in penaeid shrimps are presented. Twenty-five isolates of actinomycetes were tested for their ability to reduce infection due to WSSV among cultured shrimps. When these actinomycetes were made available as feed additives to the post-larvae of the black tiger shrimp Penaeus monodon for two weeks and challenged with WSSV, the post challenge survival showed variations from 11 to 83%. However, six isolates have shown to be the most potential candidates for further study.
Multimedia Learning in Primary Schools: Multimedia Effects, Modality Effects and Attentional Guidance

Selbst im technologischen Zeitalter des 21. Jahrhunderts gehoren Bucher (Texte und Bilder) nach wie vor zu den wichtigsten Informationsmedien einer Gesellschaft. Die dem Text- und Bildverstandnis zugrunde liegenden kognitiven Prozesse sind gut erforscht und werden bei Empfehlungen zur Gestaltung von Texten und Bildern berucksichtigt (Mayer, 2005a, fur eine Einfuhrung in multimediales Lernen). Die Forschung kann mittlerweile auf einen Pool von multimedialen Designprinzipien blicken (Mayer, 2005b, fur einen Uberblick), von denen zwei in dieser Dissertation naher beleuchtet werden. Nach dem Multimediaprinzip ist es lernforderlicher, wenn Texte zusammen mit Bildern prasentiert werden, als wenn man Texte ohne diese prasentiert (Fletcher & Tobias, 2005). Werden Texte zusammen mit Bildern dargeboten, stellt sich, dem Modalitatsprinzip folgend, ein weiterer Lernzuwachs ein, wenn der Text auditiv anstatt visuell prasentiert wird (Low & Sweller, 2005). Ein Ziel der vorliegenden Arbeit bestand darin, die Gultigkeit dieser beiden Designprinzipien in einem realistischen Kontext mit Grundschulern zu uberprufen (Experiment 1 und 2). Die Ergebnisse legen nahe, dass beide Prinzipien – scheinbar in Abhangigkeit von der zur Verfugung stehenden Lernzeit – nicht fur alle Informationsquellen (im Text prasentierte Information, im Bild prasentierte Information, sowohl im Text als auch im Bild prasentierte Information und Transferinformation; Peeck, 1974;1994) gleichermasen gelten. Bei kurzerer Lernzeit ist zudem die Gefahr gegeben, dass Bilder die Aufmerksamkeit der Grundschuler auf sich ziehen (Experiment 1); dies fuhrt zu Lerneinbusen hinsichtlich derjenigen Information, die lediglich im Text enthalten ist (shift-of-attention effect; Brunken & Leutner, 2001). Ein weiteres Ziel der Dissertation bestand darin, die Effektivitat von instruktionalen Hilfen auf die Text- und Bildverarbeitung zu untersuchen (Experiment 2). Den zugrunde liegenden theoretischen Rahmen bildete die Kognitive Theorie des Multimedialen Lernens (Mayer, 2005c; 2009) sowie ein Ansatz zur Koharenzbildung (Seufert, 2003; Seufert & Brunken, 2004). Zusammenfassend lasst sich festhalten, dass instruktionale Hilfen (Selektions-/Organisations- und Integrationshilfen) das Lernergebnis der Grundschuler nicht verbessert haben. Der theoretische Ertrag wird in einem potentiellen Beitrag der Ergebnisse zur Elaboration der Theorien des multimedialen Lernens gesehen. Der praktische Ertrag besteht darin, dass Lehrer/innen die Vorteile des Modalitatsprinzips, besonders bei kurzeren Lernzeiten, nutzen sollten. Zudem sollten sie bei der Gestaltung von instruktionalen Hilfen darauf achten, dass ihre Schuler/innen nicht von einer zu grosen Informationsflut uberwaltigt werden.
OF RESISTANCE TO PERSUASION AND OMEGA STRATEGIES by

NATURE OF RESISTANCE TO PERSUASION AND OMEGA STRATEGIES by Hayley Michele Skulborstad The current work proposed a framework to examine how people respond to omega strategies (i.e., persuasion strategies that attempt to reduce resistance) in response to counterattitudinal persuasion. Overall, it was proposed that when one has strong attitudes and is confronted with a counterattitudinal persuasive appeal, psychological conflict is aroused (e.g., dissonance, reactance, negative affect), which instigates counterarguing to avoid attitude change. In the current study, participants’ attitudes towards implementing comprehensive exams and raising tuition were assessed after reading alpha or omega strategy statements. Results indicated that alpha statements were more persuasive than omega in the domain of advocating for comprehensive exams. When expressing a preference for type of argument in the domain of raising tuition, participants preferred omega statements over alpha. Contrary to predictions, the observed effects were neither moderated by need for cognition nor preference for consistency. Implications of these findings and directions for future work are discussed.

FipsCo : A Syntax-Based System for Terminology Extraction

This paper describes FipsCo, a system developed to extract collocations and multi-word expressions from large text corpora, using a powerful syntactic parser. We will show that syntactically analysed corpora constitute a more reliable basis for MWEs extraction than raw (or shallow parsed) texts. Preliminary results supporting this view will be presented based on both French and English corpora.
Color Object Segmentation using Distance Regularized Level Set

객체분할은 영상처리와 컴퓨터비전분야의 상당히 어려운 연구대상이다. 그레이스케일 영상에 대한 영상분할은 매우 많은 방법이 발표되었으며 다양한 영상특징과 처리방법이 제시되었다. 이러한 방법들은 대개 자연상태의 칼라 영상에 적용되기 어렵다. 본 논문에서는 기하학적인 Active Contour 모델의 수정된 형태, 즉 거리정규화레벨셋(distance regularized level set evolution: DRLSE)을 이용한 방법을 제시하여 스피드 함수가 이러한 칼라요소를 반영하도록 하였으며 실험결과 정확성과 시간효율성에 있어서 우수한 결과를 보여주었다.
Acute oral toxicity and phytochemical study of "Diabenorme" and "Thuquinone" used to treat diabetes

The aim of the study was conducted to search for phytochemicals and evaluate the acute oral toxicity in mice for aqueous extracts of "Diabenorme" and "Thuquinone" used in the treatment of diabetes. "Diabenorme" is a combination of two medicinal plants: Persea americana (Lauraceae) and Anacardium occidentale (Anacardiaceae) while "Thuquinone" is composed of Pycnanthus angolensis (Myristicaceae). Phytochemical analysis was done using standard methods and acute toxicity test (OCDE 423) was performed by a fixed dose procedure consist in administration of three doses of 300, 2000 and 5000 mg/kg body weight of "Diabenorme" and "Thuquinone". Phytochemical analysis showed that the different drugs contained polyphenols, flavonoids, catechin tannins, alkaloids and saponins. Concerning acute toxicity test, no sign of toxicity and mortality were observed during the experiment after limit test of 5000 mg/kg. Thus, there were no significant differences (Fischer test, P ˃ 0.05) in the body weights between the control and treated animals. These results show that the aqueous extracts of "Diabenorme" and "Thuquinone" are potentially safe for oral consumption at acute administration up to dose of 5000 mg/kg. Further investigation is needed to evaluate its sub-acute toxicity. Keywords : Diabenorme, Thuquinone, Phytochemical screening, acute toxicity.
Does Home Ownership Crowd Out Investment in Children's Human Capital?

Parents generally care for their kids, either for altruistic or for strategic reasons. To secure them a better life than their own, they can invest in the children's human capital or accumulate real wealth to bequeath to them. In equilibrium, with complete markets and no imperfection, the marginal returns from the two strategies are equalized, an optimal distribution of children's endowment between human and financial (real) wealth is reached and no crowding out occurs. In the real world, with incomplete and imperfect markets, a displacement can occur. A strong preference for home ownership makes parents inclined to consider the house as the typical bequest-friendly asset, even at the expense of children's education. Misperceptions of the relative returns of the two different forms of wealth, with a perceived excessive premium of the returns from housing wealth, may also be at work. We consider this picture to be highly representative of the Italian situation and analyze the possible trade off between (children's) human and real capital by using the Bank of Italy's Survey of Household Income and Wealth (SHIW). Our evidence points in the direction of confirming our hypothesis.
Focal mechanism of the August 18th 2012 Mw6.3 Palu-Koro earthquake and its implication of seismic hazard

The Palu-Koro fault is a left-lateral strike-slip fault in Sulawesi within the active triple junction generated by the ongoing fast convergence of the Pacific-Philippine plate, the Indo-Australian plate and the Sunda plate. There are densely populated areas that are susceptible to earthquakes occur along the fault, and the August 18th 2012, Mw6.3 earthquake is one of such events. To better understand this earthquake and the seismic hazard in the region, we estimated source parameters of this earthquake using the Cut and Paste (CAP) inversion method with regional broadband waveform data. Our results show that the best solution of this event is 339°, 71°, −16° and 11 km for strike, dip, rake and centroid depth, respectively. Inversions using stations within different distance ranges, i.e. 0-5, 0-10° and 0-20°, reveal consistent solutions, suggesting the robustness of our result, which is also in agreement with that from the other agencies, i.e. USGS and Global CMT. We further verify the centroid depth by mo.
High‐Frequency Modeling and Optimization of E/O Response and Reflection Characteristics of 40 Gb/s EML Module for Optical Transmitters

A complete high‐frequency small‐signal circuit model of a 40 Gb/s butterfly electroabsorption modulator integrated laser module is presented for the first time to analyze and optimize its electro‐optic (E/O) response and reflection characteristics. An agreement between measured and simulated results demonstrates the accuracy and validity of the procedures. By optimizing the bonding wire length and the impedance of the coplanar waveguide transmission lines, the E/O response increases approximately 5% to 15% from 20 GHz to 33 GHz, while the signal injection efficiency increases from approximately 15% to 25% over 18 GHz to 35 GHz.
