Reproducible Benchmarking Platform for Networked Control Systems

The evolution of the Internet of Things accelerated the development of Cyber-Physical Systems. Among them, Networked Control Systems (NCSes) gained notable attention thanks to their application to industrial operations. Experimental NCSes require expertise from control, computation with the fragmentation of hardware and software used for the implementation of NCSes, represents a challenge for the reproducibility of research results. In this paper, we present the first reproducible experimental benchmarking platform for NCSes. The proposed platform is open-source and designed to be easily reproducible and extensible by anyone. Additionally, we present an NCS benchmarking methodology that aids the reproducibility of NCS experiments. To this end, it defines the parameters of the experiment and the relevant Key Performance Indicators (KPIs) that need to be observed during its execution. Finally, we evaluate in details the proposed KPIs and validate the benchmarking methodology by reproducing the platform and comparing the KPIs in different scenarios. Results present the performances of the two platforms and prove the validity of the proposed NCS benchmarking methodology.
Recognition of Relevant ORP, pH, and DO Bending Points in Ammonia Removal from Drinking Water through Online BAF System

This study was undertaken to identify the relevant bending points in ORP, pH, and DO profiles in ammonia removal through online monitoring. A novelty BAF system as newl application for drinking water treatment that equipped with ORP, pH, DO and sensors was used. Two types of polluted drinking water strength (low and high strength) with various concentrations and aeration flow were treated at a fixed-time reaction of 24 h. Experiments were conducted at four track studies (TS) of TS1 ( 50 mg/L, aeration 0.3 L/min), TS2 ( = 100 mg/L, aeration 2.0 L/min), TS3 ( 100 mg/L, no aeration) and TS4 ( 10 mg/L, aeration 0.1 L/min). The results showed that the removal of was more than 95% for TS1, TS2, and TS4. From the online monitoring performances, DO elbow and ammonia valley appeared in ORP and pH profiles, respectively. Similarly, new positive plateaus were observed in DO, indicating that the nitrifiers stopped to consume the DO after was completely removed. Hence, based on the bending points, the aeration system is possible to be automatically stopped just after DO elbow and ammonia valley appears in order to save the energy consumption and to shorten the time demands for the drinking water treatment process.
Nanocomposites damage characterisation using finite element analysis

Nanocomposites are novel materials that are receiving great attention from the aerospace community because of the inherent high strength and stiffness of the nanotubes/nanofibres embedded in the nanocomposite matrix. These features are particularly appealing to aircraft designers who strive to produce long lasting and safe components that can perform at the highest and extreme levels. However, the mechanical properties, damage initiation and propagation are yet to be fully comprehended. Consequently, in this work, the mechanical behaviour of nanofibres is characterised by finite element analysis (FEA). In particular, the stiffness mismatch of the nanofibres and the matrix are studied under simulated static loading conditions. A comparison of the formation of singular interfacial stress zones (stress concentrations) in various forms of nanofibre is then presented. It is shown that an optimised nanofibre composite design is not only influenced by the nanofibre stiffness but also by the nanofibre length and nanofibre shape. Finally, recommendations are made on producing nanocomposites with high failure strength.
Seasonal Variation in Bivalve Antioxidant Enzymes: Can they be used as indicators of heavy metal contamination?

Seasonal variations in the activity of several enzymes (glutathione reductase (GR), glutathione S-transferase (GST), and glutathione peroxidase (GPx)) involved in the glutathione cellular defence system were measured in whole tissues of the common New Zealand cockle (Austrovenus stutchburyi) as biomarkers of oxidative stress. Three sites (Glendowie, Panmure, and Tiraumea) were sampled in Tamaki Estuary, Auckland, New Zealand, that represented a heavy metal contamination gradient. These sites were selected as metal contaminants can affect the activity of antioxidant enzymes by increasing the formation of reactive oxygen species, therefore these enzymes have been proposed as biomarkers of diminished health. Cockles from the three sites were expected to show differences in enzyme activities due to the gradient in metal levels. Sites were sampled monthly over a thirteen month period, from April 2007 - April 2008. Environmental co-variables (sediment silt-clay fraction, organic matter content, chlorophyll a, median grain size, cockle condition index, water temperature and salinity) were also measured in order to relate biomarker activities to them. From these measures it was established that a gradient existed in sediment properties, water parameters, and condition index, among the three study sites. Condition index significantly correlated with both GPx (r = 0.761) and GST (r = 0.721) activity, therefore condition index provides a good measure of overall health. The silt-clay fraction of the sediment also showed a significant negative correlation with both GPx (r = -0.558) and GST (r = -0.498). GPx was the only enzyme to have significant correlations with metal concentrations including, Pb sediment concentration (r = -0.561), Cu sediment concentration (r = -0.539) and Cu tissue concentration (r = -0.530). Therefore this enzyme showed the most promise as a biomarker of contamination. The highest GPx and GST activities were measured in cockles from Glendowie, this site was characterised by lower concentrations of metals. There was seasonality observed in the activity of GPx and GST. The activity of these enzymes greatly increased from January onwards, and remained elevated for the remainder of the sampling period (until April 2008) this increase however, was more pronounced at Glendowie. The increase in enzyme activity in January could have been the result of a number of reasons including 1) changes in the cockles metabolic status due to gonadal development and spawning 2) a combination of environmental co-variables not measured in this study, or 3) a recovery from a stress event that occurred prior to sampling. Both GST and GPx showed promise as biomarkers of contamination; however GR did not as there were little differences in enzyme activities among sites. Further annual sampling at these sites should be carried out to determine if the increased GST and GPx activities in summer were the result of an abnormal event or a typical seasonal variation that occurs annually.
Stochastic modelling of 3D electric field in children brain exposed to 50 Hz magnetic field

This study focused on the evaluation of the electric field induced in the brain grey matter of a 5 years child when exposed to uniform magnetic field at 50 Hz with uncertain orientation. An innovative approach that combines Principal Component Analysis (PCA) and Gaussian process regression (Kriging method) in order to build space-dependent surrogate models was applied and validated. Preliminary results showed the feasibility of the approach.
The Islamic perspective in social work education and practice: A personal and professional journey

This conceptual paper considers aspects of a highly neglected topic: that of Islamic perspectives in social work education and practice. The paper seeks to illuminate both religiously informed values, together with those of practice, in addition to considering types of professional intervention that complement the generalised characteristics of Muslim families. The scale of problems that impact upon Muslim communities in Britain are closely considered, specifically in relation to deprivation, social alienation and domestic violence. In addition, health issues are reviewed in terms of mental health and disability.
Failure Diagnosis for Demagnetization in Interior Permanent Magnet Synchronous Motors

Since a high degree of reliability is necessary for permanent magnet synchronous motors, the detection of a precursor for the demagnetization of permanent magnets is very important. This paper investigates the diagnosis of very slight PM demagnetization. The permanent magnet volume is altered so as to mimic the effect of demagnetization. This paper investigates the influence of demagnetization by using several methods: the 3D finite element analysis (FEA) of the motor, the measurement of high-frequency impedance, and the measurement and FEA of the stator voltage and current under vector control. We have obtained the following results. The back-EMF is proportional to permanent magnet volume, and there is no difference in the demagnetization in the radial direction and in the axial direction. Even harmonics and subharmonics of flux density at the teeth tip could be useful for diagnosis if a search coil is installed there. The relatively low frequency resistance at the -axis position is useful for diagnosis. Under vector control, the stator voltage is useful except in an intermediate torque range, and the intermediate torque is expressed by a simple equation.
Technical report on laboratory outbreak investigation of sudden death syndrome in broiler chicken in Kathmandu valley Nepal 2009

The incidence of death of broiler birds above 40 days suddenly increased in the month of July to October 2009 in Kathmandu valley. Birds that were presented for post-mortem examination at the Central Veterinary Laboratory Tripureswor Kathmandu were usually found dead on their backs with wings out-stretched. Gross abnormalities recorded on post mortem examinations were: muscle oedema, pulmonary, renal and liver congestion, dark black to pale yellow streaked liver bile filled gall bladder and congestive splenomegaly, blood clot in atrium haemorrhage in duodenal muscle, whitish yellow pasty fluid in proventriculus gland, greenish coloration marked intact feed particles in gizzard and excessive mucous filled swollen intestine. Incidence rate was recorded between 1.5 to 2.5% of the flock. The mean mortality rate due to sudden death syndrome was 1.3 to 9.6%. Penicillium spp. Aspergillus spp. with CFU ranging from 56 × 104 to 62 × 105, to uncountable mold count ,Escherichia coli, Streptococcus spp. and Staphylococcus spp. were the usual organisms isolated from culture samples of liver, lung, spleen and proventriculus. The condition seems to be related to mycotoxicosis. Reduction of mortality was achieved by feed restriction, with 8 to 10% reduction in nutrient density. Supplementation of glucose containing electrolyte, liquid toxin binder, immuno-modulator, acidifier and antibiotic therapy. Key word: Sudden death syndrome, broiler birds, Kathmandu valley, Penicillium, CFU, ranging from 56 × 104 to 62 × 105 g, uncountable mold count.
MONTMORILLONITE/TIO 2 FILLER IN PA1010 MATRIX

This paper presents a study of the mechanical and thermal properties of injection molded samples of polyamide-1010 (PA1010) and polyamide-1010/(montmorillonite + TiO2) composite. The clay served as filler for the polymer matrix and also served as a substrate for growing of TiO 2 particles, whereas the resulting composite was also used as the PA1010 filler. The clay content in the PA1010 composites was varied from 0 to 8 wt. % in 5 steps. The samples were examined by Scanning Electron Microscopy (SEM), Differential Scanning Calorimetry (DSC) and Thermal gravimetry (TG). Following mechanical properties were determined: tensile strength, impact strength and elongation. Mechanical properties showed great increase with the addition of the clay filler with the peak values for the 4 wt. % content. SEM images show that morphology of the sample with 4 wt. % content of filler is similar to that of pure polyamide. The polymer fibers are ordered and aligned. The particles of the filler were also observed on the surface. Contrary to the mechanical properties the thermal properties were not improved by the addition of the filler in any amount used in this study.
Supply Response of Rice in Ghana: A Co-integration Analysis

This study presents an analysis of the responsiveness of rice production in Ghana over the period 1970-2008. Annual time series data of aggregate output, total land area cultivated, yield, real prices of rice and maize, and rainfall were used for the analysis. The Augmented-Dickey Fuller test was used to test the stationarity of the individual series, and Johansen maximum likelihood criterion was used to estimate the short-run and long-run elasticities. The land area cultivated of rice was significantly dependent on output, rainfall, real price of maize and real price of rice. The elasticity of lagged output (12.8) in the short run was significant at 1%, but the long run elasticity (4.6) was not significant. Rainfall had an elasticity of 0.004 and significant at 10%. Real price of maize had negative coefficient of -0.011 and significant at 10% significance level. This is consistent with theory since a rise in maize price will pull resources away from rice production into maize production. The real price of rice had an elasticity of 2.01 and significant at 5% in the short run and an elasticity of 3.11 in the long run. The error correction term had the expected negative coefficient of -0.434 which is significant at 1%. It was found that in the long run only real prices of maize and rice were significant with elasticities of -0.46 and 3.11 respectively. The empirical results also revealed that the aggregate output of rice in the short run was found to be dependent on the acreage cultivated, the real prices of rice, rainfall and previous output with elasticities of 0.018, 0.01, 0.003 and 0.52 respectively. Real price of rice and area cultivated are significant 10% level of significance while rainfall and lagged output are significant 5%. In the long run aggregate output was found to be dependent on acreage cultivated, real price of rice, and real price maize with elasticities of 0.218, 0.242 and -0.01 respectively at the 1% significance level. The analysis showed that short-run responses in rice production are lower than long-run response as indicated by the higher long-run elasticities. These results have Agricultural policy implications for Ghana. Key Words : Supply response, Rice, Error Correction Model, Co-integration Analysis, Ghana

The aim of this research was to study the occurrence of Vibrio spp. , Aeromonas hydrophila, Escherichia coli and Campylobacter spp. in crayfish from Azerbaijan Province using culture method and PCR assay. A total of 55 isolates were collected from 97 studied samples. Vibrio spp. , A. hydrophila, E. coli and Campylobacter spp. were detected in 26 samples (26.8%), 12 samples (12.3%), 15 samples (15.46%) and 2 samples (2.06%), respectively. Among Vibrio isolates, Vibrio vulnificus (11.3%) was the species most frequently detected followed by V. harveyi (7.2%), V. alginolyticus (2.06%) and V. mimicus (1.03%). The results of this study indicated that crayfish from the studied area contain pathogens relevant to public health.
Current transport mechanism in trapped oxides: A generalized trap-assisted tunneling model

A generalized trap-assisted tunneling (GTAT) model is proposed in this work, where an effective tunneling barrier of trapezoidal shape is considered, instead of the triangular barrier utilized in the conventional trap-assisted tunneling (TAT) model. It is demonstrated that trapezoidal barrier tunneling dominates at low electric fields (E<4 MV/cm), while triangular barrier tunneling contributes the main part of the tunneling current at high electric fields (E=6–8 MV/cm). The comparisons of this improved model and the results of the conventional TAT model at high and low electric fields are discussed. It is concluded that GTAT can more accurately model the current density-electric field (J–E) curves for the conduction enhancement of a trapped oxide film under various deposition conditions over a wider range of electric fields. This is confirmed by the comparative use of both TAT and GTAT models on experimental data obtained from existing reports. Furthermore, a simple method for determining the trap energy .
The aquatic processing of sclerophyllous and malacophyllous leaves on a Mediterranean island (Corsica) : spatial and temporal pattern

Leaves of two species, alder (Alnus glutinosa) and holm-oak (Quercus ilex), were exposed in bags of two mesh sizes in two climatically contrasting sites of a Corsican softwater stream. Leaves were incubated both in winter and in summer for about 6 months. The field experiment was designed to determine the influence of both spatial (climate) and temporal (season) variations of temperature, as well as differences in the chemical and physical properties of sclerophyilou s and malacophyllous leaves, on leaf decomposition rates. Comparisons were made between leaves colonized by macroinvertebrates and leaves protected by finemesh. In winter and summer, holm-oak leaves were colonized much less by macroinverteb rates than alder leaves. Spatial and temporal differences in leaf litter processing were mainly dependent on three factors (i) the chemical and physical properties of the leaves, (ii) the abundance of macroinvertebrates in the sediment and (iii) the temperature. The climatical pattern of tempe­ rature had a greater influence than its seasonal pattern. In contrast with many other studies, abiotic factors dominated over biotic factors in this study.
Influence of Camponotus blandus (Formicinae) and flower buds on the occurrence of Parrhasius polibetes (Lepidoptera: Lycaenidae) in Banisteriopsis malifolia (Malpighiaceae)

In the Brazilian savanna, myrmecophilous lycaenids are often found in many shrubs feeding on plant reproductive structures while are tended by ants, but only recently the role of both ants and food on the occurrence of lycaenids have received attention. In this study, we investigated the influence of Camponotus blandus (Formicinae) and flower bud abundance on the occurrence of Parrhasius polibetes, a florivorous lycaenid species that occurs in Banisteriopsis malifolia (Malpighiaceae). We also examined to what extent larval florivory was deleterious to plant reproductive outputs. Ant-exclusion experiments revealed that most P. polibetes individuals were found on branches with free C. blandus access. Nonetheless, the occurrence of larvae was not related to the abundance of ants and flower buds, indicating that the presence, rather than the abundance of mutualistic ants and food, influenced the occurrence of P. polibetes. Larvae were attended by C. blandus, which antennated frequently the dorsal nectary organ of larvae. Larval florivory was not deleterious to the plant. Banisteriopsis malifolia produces thousands of buds simultaneously and larvae feed only on a small portion of flower buds. The occurrence of P. polibetes in B. malifolia is advantageous for the larvae, since this plant supports mutualistic ants and plenty of food resources.

Effect of proficiency in English on the performance of B. Tech students in group discussion

The following study has been done to study the effect of proficiency in English on the performance of engineering students in group discussion. The hypothesis was framed in such a way that the higher the student’s proficiency in English, the better will their performance be in group discussion. The first year students of Motilal Nehru National Institute of Technology were taken as respondents. Group discussion sheets were prepared and every student was marked by three examiners on six dimensions, each dimension consisting of five marks. Class test marks of the same students were also collected. Correlation between group discussion marks and class test marks was calculated and the correlation was high. The result showed that the students who have good proficiency in English have good selfefficacy and also perform well in group discussions. Previous studies have also shown that students who have low proficiency in English have low self-efficacy, and as such they fear to perform in groups and in public. Students who are well proficient in English Language perform better and are well settled in the global market because of their better thinking and expression capability.
WEED HOSTS FOR ROTYLENCHULUS RENIFORMIS IN COTTON FIELDS ROTATED WITH CORN IN THE SOUTHEAST OF THE UNITED STATES

Lawrence, K. S. , A. J. Price, G. W. Lawrence, J. R. Jones, and J. R. Akridge. 2008. Weed hosts for Rotylenchulus reniformis in cotton fields rotated with corn in the southeast United States. Nematropica 38:13-22. The reniform nematode (Rotylenchulus reniformis) is the primary economical nematode pest of cotton (Gossypium hirsutum) in the southern states of Alabama, Louisiana, and Mississippi. Corn (Zea mays), a non-host to R. reniformis, is the principal crop rotated with cotton to reduce R. reniformis populations. In recent years, failure to manage the nematode populations have been attributed to non-controlled common weed species growing in fields farmed under the cotton-corn rotation system. The important role played by 43 weed species in sustaining reniform nematode populations in these fields was confirmed in greenhouse, microplot and field experiments. In the greenhouse, the majority of dicotyledonous weed species tested served as hosts for R. reniformis, while the monocots did not. In field microplot studies, individual weed species (Ipomoea hederacea, I. lacunosa, I. purpurea, and Senna obtusifolia) growing in association with corn increased R. reniformis nematode populations. In field trials where corn plots were treated with only a preemergence herbicide, non-controlled weed species sustained R. reniformis populations as compared to the weed-free treatments. Season long weed management during the corn rotation system is an essential agronomic practice to obtain the full benefit of the rotation, and to effectively suppress R. reniformis populations.
Flow experiences and image making: An online chat‐room ethnography

Chat rooms are a relatively new phenomenon. They provide a unique experiential locale, much like a community. They have become a popular replacement for oft-diminishing communities of yore. Qualitatively building on three overarching themes, chat rooms are put at the nexus of three diverse theoretical themes: community, flow experiences, and image management—the latter two being explored in this article. Chat rooms provide flow-like experiences to participants and allow chatters to manage and enhance their images. Given that chatters are highly involved and frequent visitors to their online community (specific chat rooms), they provide a unique opportunity to study this relatively new phenomenon, which has far-reaching, multidisciplinary implications. © 2004 Wiley Periodicals, Inc.
