Task Scheduling in Distributed Systems Model and prototype

Distributed systems is a collection of entities that cooperate to solve a problem that otherwise a single entity would not be able to solve. The use of heavy algorithms has been growing and therefore have distributed computation systems arisen. To make the best use of a distributed computation system task allocation and task scheduling algorithms has been developed. Task allocation is the process of allocating tasks to the best suitable processors of the system while task scheduling is used to determine the execution order of tasks. In some cases task scheduling also incorporate allocation process. A task is the smallest entity that can be scheduled and can be a process or a thread. Tasks are often bunched together as jobs which can include an arbitrary number of tasks. In this thesis has a general model and prototype been created which can be used in a variety of distributed systems and handle a wide range of tasks which includes tasks with execution order and deadlines. The model has been created using the best methods examined during a literature study which include the use of batch sampling, late binding and fair scheduling. A bare bone prototype has been created from the model which includes some core functionality and has been tested in regards to throughput and how balanced load it is. The throughput tests showed that the model does not lose throughput when tasks with execution order is scheduled and the load test showed that the system is fairly balanced. An evaluation of the model has been performed which shows that it works well in distributed systems and can handle a variety of tasks. The prototype has been has been tested in a small test environment which shows that it works well in smaller environments with similar requirements.
BUILDING MULTI-CLASSIFFIER SYSTEMS WITH ANT COLONY OPTIMIZATION

In recent years, the development of multi-classifier systems has become an active research field. A multi-classifier system is an ensemble of classification algorithms whose individual outputs are fused together for better accuracy and interpretability. An important aspect when designing such systems is related to the heterogeneity of the building blocks (classifiers) that make up the ensemble, since previous studies have uncovered that a more diverse ensemble often boosts up the overall classification power. Some statistical measures can be used to estimate how diverse the classifier ensembles are; they are called diversity measures . Another issue to be considered is the number of individual classifiers included in the model: the lower the number of classifiers, the simpler the resulting system. In general terms, the parsimony principle is highly desired in such ensembles, since a bulky ensemble will also be a very time-consuming model. Finding the minimal subset of individual classifiers that brings about the best system performance can be posed as a combinatorial optimization problem. In this paper, we address the problem of building multi-classifiers systems from the perspective of Ant Colony Optimization (ACO), a widely popular and effective metaheuristic optimization algorithm. The main reason behind the use of ACO lies on its strong ability to solve entangled combinatorial optimization problems. An empirical analysis is included to statistically validate the benefits of our proposal. cuyas salidas individuales se funden para una mayor precisión e interpretabilidad. Un aspecto importante en el diseño de tales sistemas está relacionado con la heterogeneidad de los bloques de construcción (clasificadores) que componen el conjunto, desde que estudios anteriores han descubierto que un conjunto más diverso a menudo aumenta la potencia de la clasificación general. Algunas medidas estadísticas se pueden utilizar para estimar cuán diversos los conjuntos de clasificadores son, ellas se llaman medidas de diversidad . Otra cuestión a considerar es el número de clasificadores individuales incluidos en el modelo: cuanto menor sea el número de clasificadores, más simple es el sistema resultante. En términos generales, el principio de parsimonia es muy deseado en tales conjuntos, desde que un conjunto voluminoso también será un modelo que consume mucho tiempo. Encontrar el subconjunto mínimo de los clasificadores individuales que produce el mejor rendimiento del sistema se puede plantear como un problema de optimización combinatoria. En este trabajo se aborda el problema de la construcción de sistemas multi-clasificadores desde el punto de vista de la Optimización de Colonia de Hormigas (ACO), un algoritmo de optimización meta heurístico ampliamente popular y eficaz. La razón principal detrás del uso de ACO radica en su fuerte capacidad para resolver problemas de optimización combinatoria entrelazados. Un análisis empírico es incluido para validar estadísticamente las ventajas de nuestra propuesta.

X-ray photoelectron spectroscopy study of irradiation-induced amorphizaton of Gd2Ti2O7

The radiation-induced evolution of the microstructure of Gd2Ti2O7, an important pyrochlore phase in radioactive waste disposal ceramics and a potential solid electrolyte and oxygen gas sensor, has been characterized using transmission electron microscopy and x-ray photoelectron spectroscopy. Following the irradiation of a Gd2Ti2O7 single crystal with 1.5 MeV Xe+ ions at a fluence of 1.7×1014 Xe+/cm2, cross-sectional transmission electron microscopy revealed a 300-nm-thick amorphous layer at the specimen surface. X-ray photoelectron spectroscopy analysis of the Ti 2p and O 1s electron binding energy shifts of Gd2Ti2O7 before and after amorphization showed that the main results of ion-irradiation-induced disorder are a decrease in the coordination number of titanium and a transformation of the Gd–O bond. These features resemble those occurring in titanate glass formation, and they have implications for the chemical stability and electronic properties of pyrochlores subjected to displacive radiation damage.
BIROn - Birkbeck Institutional Research Online Neural responses to multimodal ostensive signals in 5-month-old infants.

Infants’ sensitivity to ostensive signals, such as direct eye contact and infant-directed speech, is well documented in the literature. We investigated how infants interpret such signals by assessing common processing mechanisms devoted to them and by measuring neural responses to their compounds. In Experiment 1, we found that ostensive signals from different modalities display overlapping electrophysiological activity in 5-month-old infants, suggesting that these signals share neural processing mechanisms independently of their modality. In Experiment 2, we found that the activation to ostensive signals from different modalities is not additive to each other, but rather reflects the presence of ostension in either stimulus stream. These data support the thesis that ostensive signals obligatorily indicate to young infants that communication is directed to them.
Enhances Color Image Segmentation

- The key concern in Color Image Segmentation is more accurately and fast to do image segmentation by using algorithm. By using Algorithm, we highlight the color images in two parts that is background and Foreground. This paper focus on segmentation with flow of algorithm using n link nodes, T link nodes. This reduces the time and increase the perfection of segmentation. In which we use the grabcut Algorithm with some type of models.
Research Performance of Promising Potato Clones for Growth and Yield Characters in Bhaktapur, Nepal

: A study was conducted during 2018 in Bhaktapur district of Nepal (1348 masl) to evaluate the growth and yield of promising potato clones. Five promising clones of potato (PRP 35861.18, CIP 384866.5, PRP 226267.11, CIP 388676.1 and PRP 85861.11) provided by National Potato Research Programme, Nepal and 'Desiree' (released variety as a check) were arranged in a Randomized Complete Block Design with 4 replications. The results revealed that there was significant variation regarding the growth parameters of the clones. Desiree showed the earlier and the highest germination as compared to the promising clones. The highest plant vigor and plant height was observed in PRP 35861.18 while the highest stem thickness and ground cover were in PRP 226267.11. All the 5 promising potato clones were resistant against the late blight while the check variety (Desiree) was highly susceptible. Higher yield was obtained in PRP 85861.11 (24.5 mt/ha), CIP 388676.1 (24.43 mt/ha) and PRP 226267.11 (24.38 mt/ha). The tuber distribution also showed significant variation with the highest oversize tuber number per plant as observed with CIP 388676.1. The farmer’s ranking and organoleptic taste of boiled potato was higher for PRP 226267.11 and PRP 85861.11 respectively. Further research in other agro-ecological zones should be carried out before releasing these clones as new variety.
What drives European beech ( Fagus sylvatica L.) to death after forest fires of 1 varying severities?

(Fagus sylvatica L.) to death after forest fires of varying severities? Abstract: Predicting the timing and the amount of tree mortality after a forest fire is of paramount importance for forest management decisions related to post-fire measures. Such knowledge is particularly needed in mountainous regions where forest stands often serve as protection against natural hazards. In this paper, we focus on drivers and temporal trends in mortality processes of fire-injured beeches (Fagus sylvatica L.). We studied beech forests in the Southern European Alps, which burnt between 1970 and 2012. The results show that beech trees—which obviously lack fire-resistance traits—experience increased mortality within the first two decades post-fire after fires of moderate and high burn severity. Beech mortality was ubiquitous in high severity sites, whereas taller beeches had a higher survivability after fires of moderate severity, representing a crucial ecological legacy for natural beech regeneration. In contrast, mortality remains low and at a level similar to unburnt beech forests for low burn severity sites. Interestingly, fungi initiating post-fire tree mortality appeared to differ from fungi occurring after mechanical injury. From a practical point of view, insight gained regarding post-fire mortality is of great help in planning post-fire silvicultural measures.

In 32 contrast, mortality remains low and at a level similar to unburnt beech forests for low 33 burn severity sites. 34 Among mortality drivers, fungal infestation and the presence of fungal sporulation in particular was found to be most significant.

The effects of dietary supplementation of Allium sativum on some vital biochemical parameters in male Albino rats .

This study investigated the effects of Garlic ( Allum sativum ) on plasma lipid levels, serum proteins and electrolytes in albino rats. Graded dietary supplementations of garlic viz: 0, 5, 10, 15, 20, and 25 % administered to sixty (60) apparently healthy male albino rats of the Wistar strain in five groups of ten (10) rats each. The Allium was supplemented for 30 days in a complete randomized manner. A sixth group of ten rats served as the unsupplemented control. The result showed a significantly (p<0.05) decreased plasma lipid (total cholesterol) level in a dose dependent manner. The serum albumin was significantly (p<0.05) decreased at 20 and 25 % supplementation levels. Though there was an increase in serum globulin at higher supplementation levels, the increase was not significant. There was also significant (p<0.05) reduction in serum sodium and calcium levels as the garlic supplementation levels increased. There was however no significant (p>0.05) effect on serum potassium levels in the supplemented groups. This study reveals that garlic has an effect on the dynamics of plasma lipids and serum proteins, and key electrolytes concentrations. These investigations infer that garlic intake has some desirable effects, but caution should be exercised in its consumption to minimize some possible adverse effects which may be associated with an overdose or excess intake.
Title: THE INSPIRED SINEWAVE TECHNIQUE: A NOVEL METHOD TO MEASURE LUNG VOLUME AND VENTILATORY HETEROGENEITY

The Inspired Sinewave Technique (IST) is a novel method which can provide simple, noninvasive cardiopulmonary measurements. Over successive tidal-breaths the concentration of a tracer gas (i.e. nitrous oxide, N2O) is sinusoidally modulated in inspired air. Using a singlecompartment tidal-ventilation lung model, the resulting amplitude/phase of the expired sinewave allows estimation of end-expired lung volume (ELV), pulmonary blood flow and three indices for ventilatory heterogeneity (VH; ELV180/FRCpleth, ELV180/FRCpred and ELV60/ELV180). This investigation aimed to determine: the repeatability and agreement of ELV with FRCpleth, and, as normal ageing results in well-established changes in pulmonary structure and function, whether the IST estimates of ELV and VH are age dependent. 48 healthy never-smoker participants (20-86 years) underwent traditional pulmonary function testing: (e.g. spirometry, body plethysmography) and the IST test which consisted of 4 minutes of quiet breathing through a facemask while inspired N2O concentrations are oscillated in a sinewave pattern with a fixed mean (4%) and amplitude (3%) and a period of either 180 seconds or 60 seconds. ELV180/FRCpleth and ELV180/FRCpred were age dependent (average decreases of 0.58% and 0.48% per year) suggesting an increase in VH with advancing age. ELV showed a mean bias of -1.09L vs. FRCpleth, but when normalised for the effects of age this bias reduced to -0.35L. The IST test has potential to provide clinically useful information, (e.g. for mechanically ventilated patients), but these findings suggest that the increases in VH with healthy ageing must be accounted for in clinical investigations.
for Th1 Priming Them of Human Dendritic Cells and Licenses Leptin Promotes Differentiation and Survival

Leptin is an adipocyte-derived hormone/cytokine that links nutrition, metabolism, and immune homeostasis. Leptin is capable of modulating several immune responses. However, the effect of leptin on dendritic cells (DCs) has not yet been recognized. Because DCs are instrumental in the development of immune responses, in this study, we evaluated the impact of leptin on DC activation. We demonstrated the presence of leptin receptor in human immature and mature DCs both at mRNA and protein level and its capacity to transduce leptin signaling leading to STAT-3 phosphorylation. We found no consistent modulation of DC surface molecules known to be critical for their APC function in response to leptin. In contrast, we found that leptin induces rearrangement of actin microﬁlaments, leading to uropod and rufﬂe formation. At a functional level, leptin up-regulates the IL-1 (cid:1) , IL-6, IL-12, TNF- (cid:2) , and MIP-1 (cid:2) production. Coincident with this, leptin-treated DCs stimulate stronger heterologous T cell responses. Furthermore, we found that leptin down-regulates IL-10 production by DCs and drives naive T cell polarization toward Th1 phenotype. Finally, we found that leptin partly protects DCs from spontaneous and UVB-induced apoptosis. Consistent with the antiapoptotic effect of leptin, we observed the activation of NF- (cid:3) B and a parallel up-regulation of bcl-2 and bcl-x L gene expression. These results provide new insights on the immunoregulatory function of leptin demonstrating its ability to improve DC functions and to promote DC survival. This is of relevance considering a potential application of leptin in immunotherapeutic approaches and its possible use as adjuvant in vaccination protocols. The
Bellman partial differential equation and the hill property for classical isoperimetric problems

The goal of this note is to have a systematic approach to generating isoperimetric inequalities from two concrete type of PDEs. We call these PDEs Bellman type because a totally analogous equations happen to rule many sharp estimates for singular integrals in harmonic analysis, and such estimates were obtained with the use of Hamilton--Jacobi--Bellman PDE. We show how classical inequalities of Brascamp--Lieb, Prekopa--Leindler, Ehrhard are particular case of this scheme, which allows us to augment the stock of such inequalities. We approach the isoperimetric inequalities as a maximum (minimum) principle for special types of functions. These functions are compositions of "Bellman function" and an appropriate flow built on test functions. Then the existence of maximum (minimum) principle for such compositions can be reduced to the requirement that Bellman function satisfies a concrete class of nonlinear PDE (written down below). We are left to solve this nonlinear PDE (sometimes a possible task) to enjoy isoperimetric inequalities. The nonlinear PDE that we will describe in this article can be reduced sometimes to solving Laplacian eigenvalue problem, $\bar{\partial}$-equation of certain type or just the linear heat equation.
Chimera: An Elastically Scalable High Performance Streaming System with a Shared Nothing Architecture

—On a daily basis, Internet services experience growing amount of trafﬁc that needs to be ingested ﬁrst, and processed subsequently. Technologies to streamline data target horizontal distribution as design tenet, giving off maintainability and operational friendliness. The advent of the Internet of Things (IoT) and the progressive adoption of IPv6 require a new generation of scalable data streamline platforms, bearing in mind easy distribution, maintainability and deployment. Chimera is an ultra-fast and scalable Extract Transform and Load (ETL) platform, designed for distribution on commodity hardware, and to serve ultra-high volumes of inbound data, processing in real-time while offering a simplistic fault model. It strives at putting together top performance technologies to solve the problem of ingesting huge amount of data delivered by geographically distributed agents. It has been conceived to propose a novel paradigm of distribution, leveraging a shared nothing architecture, easy to elastically scale and to maintain. It reliably ingests and processes huge volumes of data: operating at the line rate, it is able to distribute the processing among stateless processors, which can dynamically join and leave the infrastructure at any time. Experimental tests show relevant outcomes intended as the ability to systematically saturate the I/O (network and disk), preserving reliable computations (at-least-once delivery policy).
The Role of Salicylic Acid in the Induction of Cell Death in Arabidopsis acd11 1

Salicylic acid (SA) is implicated in the induction of programmed cell death (PCD) associated with pathogen defense responses because SA levels increase in response to PCD-inducing infections, and PCD development can be inhibited by expression of salicylate hydroxylase encoded by the bacterial nahG gene. The acd11 mutant of Arabidopsis ( Arabidopsis thaliana L. Heynh.) activates PCD and defense responses that are fully suppressed by nahG . To further study the role of SA in PCD induction, we compared phenotypes of acd11 / nahG with those of acd11 / eds5-1 and acd11 / sid2-2 mutants deﬁcient in a putative transporter and isochorismate synthase required for SA biosynthesis. We show that sid2-2 fully suppresses SA accumulation and cell death in acd11 ,althoughgrowthinhibition andprematureleafchlorosisstilloccur.Inaddition,applicationofexogenousSAto acd11 / sid2-2 is insufﬁcient to restore cell death. This indicates that isochorismate-derived compounds other than SA are required for induction of PCD in acd11 and that some acd11 phenotypes require NahG-degradable compounds not synthesized via isochorismate.
