Inverter-Based Diesel Generator Emulator for the Study of Frequency Variations in a Laboratory-Scale Autonomous Power System

This paper presents the modeling, simulation and practical implementation of an inverter-based diesel generator emulator. The main purpose of this emulator is for the study of frequency variations in diesel-based autonomous power systems in a laboratory environment where the operation of a real diesel generator is not possible. The emulator basically consists in a voltage source inverter with a second order output filter which voltage references are given by the model of the diesel generator. The control of the emulator is based on the digital signal processor TMS320F2812, where the mathematical models of the diesel generator and the control of the inverter are computed in real-time. Parameters for the model were obtained from commercially available components. Experimental results for different values of speed droop showed that the emulator achieves a satisfactory performance in the transient and stationary response. For the stationary response, the measured frequency deviates from theoretical values with a mean absolute error of: 0.06 Hz for 0% droop, 0.037 Hz for 3% droop, and 0.087 Hz for 5% droop. For the transient response, the measured frequency nadir deviates from simulations in: 0.05 Hz for 0% droop, 0.02 Hz for 3% droop, and 0.1 Hz for 5% droop.
Passive Diffusion Processes Govern the Initial Stages of Cell Penetration into Electrospun Scaffolds

The inability to rapidly seed and populate electro spun tissue engineering scaffolds at high cell density in tissue culture represents a long recognized limitation to this emergent technology. This, despite the interconnected nature of pores that are present in these scaffolds. A broad spectrum of electro spun scaffolds composed of natural [1] synthetic polymers [2,3] and blends of natural and synthetic polymers [4] are extensively infiltrated by inflammatory, interstitial and vasculogenic cells when they are implanted in situ [5]. Cell infiltration is likely far more efficient in this setting due to a variety of variables including the presence of an intact immune response and the penetration of soluble of grow factors from the surrounding environment. The environmental factors that lead to the penetration of cells into implanted electro spun scaffolds have not been fully defined or even remotely reproduced in tissue culture. A fundamental objective of the classical tissue engineering paradigm is to produce tissues in vitro that can ultimately be used to replace or augment the function of damaged, diseased or otherwise missing organs. To fulfill this promise, regardless of the identity of the scaffold, strategies to fully populate tissue engineering scaffolds in vitro must be developed.
Environmental Conditions, Entrepreneur Alertness and Social Capital on Performance

This study addresses the important question of causal complexity as it relates to the influence of social capital, entrepreneurial alertness and the entrepreneurship environment on business performance. Using a relatively new methodological approach, namely fuzzy-set qualitative comparative analysis (fsQCA), this paper aims to investigate alternative complex antecedent conditions (or causal recipes) that lead to high performance. Based on a survey of 194 entrepreneurs in China, this paper shows that business performance is likely to be the result of a combination of causal factors. This study finds that: (1) four different configurations of social capital, entrepreneurial alertness and entrepreneurship environment were “equifinal” causes of high performance, and (2) market openness should fit other environmental conditions to achieve high performance. This study contributes to research on entrepreneurship by applying the ideas of “equifinality” and “fit” to entrepreneurial characteristics and environment theory.
Signal Quality Improvement for Mobile Phone Using the Pico Cells in Dense Phone Usage Areas

A Pico cell is a small, low-cost, fast coverage and extra capacity which can be used wherever the signal drops. The low cost of these cells and the easy installation as compared with BTSs is very important feature, one more feature is that Pico cells are more effective in dense phone usage areas and at the extremely high buildings, also as its radiation power is much less than BTSs so it has no health effects on human. This paper makes a design to support the network by using the technique of Pico cells in order to improve the signal quality inside dense phone usage areas and take multiple scenarios to show the importance of using such type of cells. The results show the advantages of using this cell to improve the signal quality especially in dense phone usage areas.
Propaedeutics of the Systematic Review Development; Effectiveness of Hallux Valgus Surgery: Systematic Review Partial Results

Background: Systematic review (SR), as secondary research is in the context of Evidence-Based Healthcare (EBHC) classified as the most important and valuable type of publication within the level of evidence hierarchy. Hallux valgus (HV) is a common forefoot deformity. In the current literature, there is no SR which has reviewed the effect of HV surgery on gait, pain or function in the global evidence. Aim: Main aim of this propedeutically focused paper was to highlight the importance of SR within EBHC approach and explain rigorous and systematic methods of its development by example of partial results of the SR focusing on evaluation of the effect of the hallux valgus surgery. Medhods: Firstly, we formulated an answerable review question and specified inclusion and exclusion criteria. Protocol of the SR was prepared using soware developed by Joanna Briggs Institute for SR preparation. Systematic search of published and unpublished studies included three steps: 1. Initial search in Medline, Embase and Cinahl; 2. secondary search in 13 databases; 3. hand-search in the reference lists of relevant papers. We have searched randomized controlled trials (RCT) in any date and language. Results: We found 2412 papers and deleted 767 duplicates. en a paper retrieval according to inclusion and exclusion criteria and critical appraisal of methodological quality were done using standardized critical appraisal instruments JBI-MAStARI. 27 RCT were included into SR. Currently, we are extracting data using JBI MAStARI and preparing them for meta-analysis. Partial results showed heterogeneity of used method for evaluation of pain and patient satisfaction aer HV surgery in included RCT. Conclusions: SR is a very important link between scientific evidence and their implementation into clinical practice. Evidence-Based approach can be used in all areas with high quality of primary scientific evidence.
Technological Change and Political Mobilization: Evidence from India (Job market paper)

This paper empirically examines the role played by a technological change in Indian agriculture (adoption of High Yielding Variety (HYV) seeds) in the political mobilization of culti- vators in Northern India in 1970s and 1980s. Using panel data from the state of Uttar Pradesh (UP) from 1962-1989, I nd that the districts that had the largest impact of the green revolution also had the biggest increase in the vote share of the Janata party (a new rural party). This change is accompanied by a fall in political fractionalization, even as eective competition increased over the period. I hypothesize that technology adoption consolidates rural votes by aligning the policy preferences of previously disparate rural groups. I then look at public good provision to see if this substantive political change induced any policy changes. I examine the provision of schools as previous literature has documented the increasing returns to human capital with the advent of the new technology. I nd that an increase in the vote share of the Janata party in a district is associated with an increased proportion of villages in that district that have a school (primary, middle and high schools).
DESIGNING THE STRUCTURE FOR LOWERING THE DYNAMIC ENERGY CONSUMPTION ON SCN

: The suggested architecture is dependent on a lately developed sparse clustered network using binary connections that on-average eliminates the majority of the parallel evaluations carried out throughout a search. Following an array of design parameters, like the quantity of CAM records, the power consumption and also the search delay from the suggested design are 8%, and 26% of this from the conventional NAND architecture, correspondingly, having a 10% area overhead. Therefore, the dynamic energy use of the suggested design is considerably lower in comparison with what conventional low-power CAM design. We advise a minimal-power content-addressable memory (CAM) having a new formula for associativity between your input tag and also the corresponding address from the output data. Given a port tag, the suggested architecture computes a couple of options for the position of the matched up tag and performs the evaluations in it to discover a single valid match. TSMC 65-nm CMOS technology was utilized for simulation reasons. A design methodology in line with the plastic area and power budgets, and gratification needs is talked about.

A privacy protection algorithm based on hierarchical multiple sensitive attributes allowed by least mean square criterion

Based on L-diversity multiple sensitive modules, a hierarchical multiple sensitive attributes algorithm is proposed according to least mean square criterion --L-LMSU (L-Least Mean Square Uniqueness). The algorithm makes a hierarchical strategy according to the frequencies of the whole attributes firstly. Beyond the hierarchical strategy, the algorithm could decrease the hidden loss because of non-uniform distribution of attributes when releasing privacy data in groups. Analysis and experiments show that L-LMSU is with linear time complexity and could improve the availability of released privacy data and time performances effectively.
Extracellular Synthesis of SilverNanoparticles Using Actinomycetes andtheir Antibacterial Activity

In the present study, isolate and identify the pigment producing actinomycetes, to identify the bioactive compounds and biologically synthesis silver nanoparticles against pathogenic bacteria. A total of seven actinomycetes were isolated from soil samples and tested against pathogenic bacteria. Out of seven isolates, three isolates [A1, A3 and A7] showed better result against pathogenic bacteria by primary screening. Out of three isolates, A1 and A7 were subjected to secondary screening, identification, growth study (temperature and pH), mass multiplication and synthesis of silver nanoparticles methods. The potential isolates was identified by morphological and biochemical tests (Streptomyces sp.). The optimum temperature as room temperature 28oC and favorable pH was 7. The cell free extract of potential isolate was assessed for the synthesis of silver nanoparticles. The biologically synthesized silver nanoparticles showed major peak at 420 nm. Synthesized nanoparticles also exhibited antibacterial activity against bacterial pathogens
HYBRID FUNCTIONS METHOD BASED ON RADIAL BASIS FUNCTIONS FOR SOLVING NONLINEAR FREDHOLM INTEGRAL EQUATIONS

A numerical technique based on hybrid of radial basis functions including Guassians (GAs) and Multiquadrics (MQs) is pro- posed to obtain the solution of nonlinear Fredholm integral equations. Zeros of the shifted Legendre polynomials are used as the collocation points. The integral involved in the formulation of the problems are ap- proximated based on Legendre-Gauss-Lobatto integration rule. Some numerical examples illustrate the accuracy and validity of the proposed method.
Interactions among squirrels, mycorrhizal fungi, and coniferous forests in Oregon

We examined the mycophagy (ingestion of fungi) of squirrels of five genera and eight species in the coniferous forests of Oregon. Data from 644 dietary samples demonstrated that scjuirrels of all eight species are mycophagous and eat the belowground fruiting bodies of at least 26 genera of mycorrhizal fungi. Four species are primarily arboreal and active throughout the year; the other four are primarily terrestrial and hibernate during winter. Of the squirrels examined, only the northern flying squirrel [Glaucomys sahrinus [Shaw]) is nocturnal and almost exclusively a fungivore. The flying squirrel is used to illustrate the dynamics of all the squirrels in association with hypogeous mycorrhizal fungi, nitrogen-fixing bacteria, yeast, and coniferous trees in Oregon forests because we have studied it the most. Squirrels may prove to be vital links among different processes within temperate coniferous forests. Although early studies of small-mammal food habits included a few papers dealing with mycorrhizal fungi (e.g., Bakerspigel 1956, 1958, Dowding 1955, Hamilton 1941, Tevis 1952, 1953, Whitaker 1962, Williams and Finney 1964), the first interdisciplinary studies to examine the role of small mammals as dispersal agents for spores of mycorrhizal fungi are recent (Kotter and Farentinos 1984a, 1984b, Maser, Trappe, and Nussbaum 1978, Maser, Trappe, and Ure 1978, Trappe and Maser 1976, 1977, Ure and Maser 1982). The first extensive literature review of smallmammal mycophagy was published in 1978 (Fogel and Trappe 1978). Symbioses between small-mammal and mycorrhizal fungus have also been documented recently in Europe (Blaschke and Baumler 1986, Durrieu et al. 1984, Froidevaux 1981). Only now are researchers beginning to understand the importance of nitrogen-fixing bacteria in the symbiotic relation of small-mammal, mycorrhizal fungus, coniferous tree mutualism (Ei ct al. 1986). In this paper we present data on the fungal diet of squirrels of four genera and six species from the coniferous forests of Oregon, and we examine potential interactions among five genera of eight species of mycophagous s(juirrels and the coniferous forests of Oregon. In addition to giving new data on the 118 squirrels, this paper is intended as a synthesis of the potential ecological roles s(juirrels play in coniferous forests of the Pacific Northwest. Other studies of the northern flying squirrel (Maser et al. 1985, 1986), the' yellow-pine chipmunk {Eutamias amoenus [J. A. Allen]) (Maser and Maser 1987), and the Siskiyou chipmunk {Eutamias siskiyou A.H. Howell) (Mclntire 1980) are based on 524 samples. So, for all practical purposes, this paper is based on data from 644 squirrels in Oregon forests.
The Fermi GBM gamma-ray burst time-resolved spectral catalog: brightest bursts in the first four years

We aim to obtain high-quality time-resolved spectral fits of gamma-ray bursts (GRBs) observed by the Gamma-ray Burst Monitor (GBM) on board the Fermi Gamma-ray Space Telescope. We perform time-resolved spectral analysis with high temporal and spectral resolution of the brightest bursts observed by Fermi GBM in its first 4 years of mission. We present the complete catalog containing 1,491 spectra from 81 bursts with high spectral and temporal resolution. Distributions of parameters, statistics of the parameter populations, parameter-parameter and parameter-uncertainty correlations, and their exact values are obtained and presented as main results in this catalog. We report a criterion that is robust enough to automatically distinguish between different spectral evolutionary trends between bursts. We also search for plausible blackbody emission components and find that only 3 bursts (36 spectra in total) show evidence of a pure Planck function. It is observed that the averaged time-resolved low-energy power-law index and peak energy are slightly harder than the time-integrated values. Time-resolved spectroscopic results should be used when interpreting physics from the observed spectra, instead of the time-integrated results.
A New Improved Camshift Algorithm and Its Experimental Analysis

Camshift is an adaptive tracking algorithm based on color histogram with the advantages of translation, scale and rotation invariance, which is widely used in visual tracking. But in the moving scenes, due to the changing background, occlusion and environmental illumination, the tracking effectiveness and efficiency will be affected and even lead to loss of moving target. Combined with the idea of both bottom-up and top-down, this paper suggests an improved one by using pixel filtering, histogram improvement and occlusion judgment, as well as Kalman filter. The comparative analysis results on the traditional Camshift algorithm and combined with Kalman traditional Camshift algorithm demonstrate that the proposed algorithm enhances the accuracy and stability in complex condition in an effective way and improves the real-time performance as well. Keywords—Visual Tracking; Camshift Algorithm; Kalman Filter; Color Histogram; Occlusion Judgment

Real-time Monitoring and Detection of Drinkdriving and Vehicle Over-speeding

Drink-driving and over-speeding of vehicles are the major causes of injuries and deaths on the road globally and South Africa (SA) is not an exception. Different systems which are currently used in detecting high alcohol concentration in drivers’ breath and detecting vehicles that exceeds stipulated speed limit are not effective, efficient and poses health risks to traffic personnel. In an attempt to provide effective solutions to these challenges, this paper proposed a smart transportation system for real-time detection of drinkdriving and over-speeding on the roads using technology of vehicular networks. The objective is to allow for early intervention by traffic personnel aim at saving lives before actual accident occurred. We designed a theoretical framework of the system and implemented an application prototype which is web-based for use by traffic personnel to monitor the detection of traffic offenders in the capacity of drink-driving and overspeeding. We presented and discussed the operation of the system as well as the functionalities it offers. Additionally, we utilized the application to simulate the actual system and based on its working, we found that the system is feasible and can accomplish the tasks of road safety more effective than the existing approaches.

CONCURRENT BOOST WITH ADJUVANT BREAST HYPOFRACTIONATED RADIOTHERAPY AND TOXICITY ASSESSMENT

Background : The use of shorter radiotherapy schedules has an economic and logistic advantage for radiotherapy departments, as well as a high degree of patient convenience. The aim of this study is to assess the acute and short-term late toxicities of a hypofractionated radiotherapy schedule with a concomitant boost. Methods : We enrolled 57 eligible patients as group A. These patients received 42.5 Gy in 16 fractions of 2.66 Gy each to the whole breast over 3.2 weeks. A concomitant electron boost of 12 Gy in 16 fractions was also administered which gave an additional 0.75 Gy daily to the lumpectomy area for a total radiation dose of 54.5 Gy. Toxicity was recorded at three weeks and at three months for this group as well as for a control group (group B). The control group comprised 76 eligible patients treated conventionally with 50 Gy to the whole breast over five weeks followed by a sequential electron boost of 12 Gy in 2 Gy per fraction. Results : There were no statistically significant differences observed in the incidence of acute skin toxicity, breast pain, and edema recorded at three weeks or pigmentation and fibrosis recorded at three months between the two groups (P0.05). Conclusion : The results of this study suggest there are no increased acute and short- term late toxicities affiliated with the hypofractionated schedule plus a concomitant boost as prescribed compared to the conventional fractionation of adjuvant breast radiotherapy. Large randomized trials and long-term follow-up are needed to confirm these favorable findings.
PERFORMANCE TRENDS OF ON-CHIP SPIRAL INDUCTORS FOR RFICS

Performance trends varying with different geometrical parameters for on-chip spiral inductors: (a) with fixed inner-dimension, (b) with outer-dimension, and (c) variation in both inner- and outer- dimensions are extensively investigated in this paper. The relationships for the inductance, Q-factor and self-resonance frequency (SRF) with various geometrical parameters, such as track width, track spacing, and turn numbers are examined on an extensive experiment basis. These performance trends can be a good guideline for practical inductor designs in RFICs.
