Channel modeling for Urban and Hilly terrain using Jakes, Gaussian and Flat spectrum for Ad-hoc network

The radio channel places fundamental limitations on the performance of mobile ad hoc wireless networks. In the mobile radio environment, fading due to multipath delay spread impairs received signals. The purpose of this thesis is to develop a radio channel model and examine the effect of various parameters on channel behaviour that is representative of environments in which mobile ad hoc wireless networks operate. The various physical phenomena considered are outdoor environments, fading and multipath propagation, type of terrains, and mobility (Doppler shift). In this paper we are analysing channel model performance of ad-hoc network in terms of number of taps mobile Velocity and Doppler Spectrum and improve the performance of wireless network using jakes spectrum.
ADOPTION STATUS AND FIELD LEVEL PERFORMANCE OF DIFFERENT PROTECTED STRUCTURES FOR VEGETABLE PRODUCTION UNDER CHANGING SCENARIO

Vegetable crops are short duration in nature and sudden changes in climatic parameters at any developmental phase can affect the normal growth, flowering, pollination, fruit development and subsequently decrease the crop yield. Protected structures can play important role to minimize the impact of climatic change effect. Farmers are gradually adopting different protected structures to combat the climatic vagaries and emerging challenges in vegetable production. To understand adoption and utilization pattern of protected structures, an investigation was carried out during 2011-2012 through questionnaire survey in different vegetable belt of the district. The study revealed that habit of adoption of protected structures namely agro-shade net house, poly-tunnel, poly-house and pro-tray have increased during last 5 years. Poly-tunnel was the most used structure utilized for raising vegetable seedling during rainy season. Seedling rising in pro-trays and crop production inside agro-shade net also gaining popularity among the farmers. Although poly-tunnel was the most adopted structure but the performance of poly-house was emerged as best structure in field condition. Additional investment and lack of knowledge for proper utilization were the major factors hindering the large scale adoption of protected structures.

Emergence of Plecoptera in two lotic habitats in the Oulanka National Park, northeastern Finland

The samples of emerging stoneflies obtained using slit traps indicated a three-phase course of emergence : early spring (two winter stoneflies), early summer (especially Perloidea) and autumn (a few abundant Nemouroidea). Early June and middle August are recommended as the sampling periods for benthon as far as stoneflies for bio-index studies are concerned.
Model-Based development of control systems for forestry cranes

Model-based methods are used in industry for prototyping concepts based on mathematical models. With our forest industry partners, we have established a model-based workflow for rapid development of motion control systems for forestry cranes. Applying this working method, we can verify control algorithms, both theoretically and practically. This paper is an example of this workflow and presents four topics related to the application of nonlinear control theory. The first topic presents the system of differential equations describing the motion dynamics. The second topic presents nonlinear control laws formulated according to sliding mode control theory. The third topic presents a procedure for model calibration and control tuning that are a prerequisite to realize experimental tests. The fourth topic presents the results of tests performed on an experimental crane specifically equipped for these tasks. Results of these studies show the advantages and disadvantages of these control algorithms, and they highlight their performance in terms of robustness and smoothness.
Incorporating weather: a comparative analysis of Average Annual Daily

36 Average Annual Daily Bicyclists (AADB) is commonly used in a wide range of cycling-related 37 research and practical applications. It is generally estimated by averaging the daily cyclist totals 38 recorded by a long-term automatic counter, or by using such a counter to extrapolate short-term 39 counts. The latter method is commonly referred to as the expansion factor method, and has been 40 shown to produce estimates with considerable error. To help mitigate this error, this study 41 proposes two AADB estimation methods, one of which uses a cycling-weather model to adjust 42 short-term counts, and one of which is based on individual daily totals from a long-term count 43 site (as opposed to annual averages by day or by month). These methods are compared to two 44 more traditional expansion factor methods. The weather and disaggregate methods out45 performed the traditional methods, with the latter producing an average absolute relative error of 46 roughly 14% when based on just one day of short-term data. 47
Human Nature, Anthropology, and the Problem of Variation

In this essay, I begin with an overview of a traditional account of natural kinds, and then consider David Hull's (1986) critique of species as natural kinds and the associated notion of human nature. Second, I explore recent "liberal" accounts of human nature provided by Edouard Machery (2008) and Grant Ramsey (2013) and criticized by Tim Lewens (2012). They attempt to avoid the criticisms of- fered by Hull. After examining those views, I turn to Richard Boyd's (1988; 1999) Homeostatic Property Cluster account of natural kinds which is flexible but detailed enough to avoid Hull's criticisms but also those affecting the more recent views. We then consider what I call the "problem of variation. " Fourth, I consider two case studies -- the basic emotions and facial expressions and inbreeding avoidance and incest taboos. I argue that the former is a component of a Boydian human nature but the latter is not. The conclusion is that if there is a human nature, it must be argued for on a case-by-case basis. And, one of most discussed cases thought to be part of our nature is simply not.
A comparative study of fatty acid profiles of fat in commercial Spanish suckling kids and lambs

Fatty acid profiles are a major contributor to meat quality in small ruminants. Nevertheless, while fatty acid profiles from suckling lambs have been extensively studied they are virtually unknown in suckling kids. Fatty acid profiles of intramuscular and kidney knob fat depots of suckling kids were compared with fatty acid profiles of lambs with a quality label in the Spanish market. Forty suckling kids from Blanca Celtiberica (BC), Moncaina (Mo), Negra Serrana (NS) and Murciano Granadina (MG) breeds and 20 Churra male suckling lambs labelled with ‘Lechazo de Castilla y Leon’ Protected Geographic Indication were slaughtered at commercial live weights (12 kg). In both depots differences in the unsaturated fatty acid profile were observed between breeds. The most pronounced differences were observed between meat goat breeds (BC, Mo and NS) and lambs, whilst a greater similarity in the fatty acid profile was observed between kids from dairy goat breeds (MG) and lambs. The lowest polyunsaturated fatty acid content was observed in meat goat breeds (approximately 21 to 22% of total fatty acids detected in the intramuscular fat). No significant differences in atherogenic index and desirable fatty acid content (range 68 to 70% of total fatty acids detected) were observed. However, a more favourable (lower than 8.07) n-6/n-3 ratio was observed in meat goat breeds. The use of fatty acid profiles from intramuscular and kidney knob fat could be proposed as a tool to differentiate goat kids and lambs. The fact that intramuscular fat from suckling kids and lambs shows appropriate lipid nutritional indices and their low carcass fatness indicate that moderate consumption of suckling kid and lamb meat may contribute to an overall balanced diet for humans.
REPATRIATION: REFLECTIONS ON ORGANIZATIONAL PRACTICES AND ITS IMPLICATIONS ON INDIVIDUALS, AROUND THE GLOBE

This paper aims to understand and analyze the field and focus of study on repatriation, promoting a discussion based on specific literature review. The motivation of this research comes from some precariousness in the emphasis to this stage of the process given by academic studies. Having the organization as field of study, the reviewed studies reinforce the practices and roles on a universalistic approach and, afterwards, aggregate the perspective of differentiation between size and moment of the company. In most cases, they are theoretical propositions, which have not been tested. On the other hand, the studies that emphasize the individuals reinforce individual nuances and changing processes, questioning the organizational practices, challenging the adoption of the Universalistic approach. Subjects such as knowledge (retention and management) and ROI were little discussed by this paper due to the few references available, but will be key to the future of the field.

Regional Unemployment in Poland: A Legacy of Central Planning

We model job reallocation and unemployment as outcomes jointly determined by the structure of inherited social capital within a two-sector Optimal Speed of Transition model. Treating regions of Poland as independent labour markets, the socio-economic inheritance of regions is found to be a legacy of planning that determines regional job reallocation rates. In turn, higher rates of (instrumented) regional job reallocation is shown to boost regional unemployment turnover, reduce the duration of frictional and increase the incidence of structural unemployment. At the regional level, the benefit system facilitates the job reallocation process and accumulates out-of-date human capital.
The Impact of Severe Weather on Sector Capacity

It is well-accepted that sector capacity is reduced when severe weather is present in the sector. However, no accepted algorithms for calculating the capacity under severe weather impact have been developed. We have proposed methods to estimate the impact of severe weather on sector capacity. These methods introduced three types of weather impact index: 2D weather coverage, 3D weather avoidance field coverage, and flow-based sector capacity reduction ratio. This paper discusses the correlations between the sector throughput and these three sector weather impact indexes with statistical analysis of the historical data. The statistical correlation between the actual sector throughput and the sector weather impact indexes reveals the current operation of the Air Traffic Management system and suggests the acceptable algorithm for calculating the capacity under severe weather impact. Keywords-Traffic flow management, sector capacity, sector weather impact index, flow capacity, traffic flow pattern
How Important is to Account for Water When Modeling Biomolecular Complexes

Taking account of the presence of water molecules is sometimes crucial for free energy calculations to predict binding ability of molecules to receptors, a main subject for drug design. This mini-review seeks to identify the importance of knowing the influence of these molecules in such studies to better achieve correct predictions for drug candidates. Participation of some water molecules need to be considered in docking studies although they have been usually neglected.
Hybrid features-based prediction for novel phish websites

Phishers frequently craft novel deceptions on their websites and circumvent existing anti-phishing techniques for insecure intrusions, users’ digital identity theft, and then illegal profits. This raises the needs to incorporate new features for detecting novel phish websites and optimizing the existing anti-phishing techniques. In this light, 58 new hybrid features were proposed in this paper and their prediction susceptibilities were evaluated by using feature co-occurrence criterion and a baseline machine learning algorithm. Empirical test and analysis showed the significant outcomes of the proposed features on detection performance. As a result, the most influential features are identified, and new insights are offered for further detection improvement.
Real-Time Gesture Recognition with a 2D camera

There has been a vast improvement in Human-Computer Interaction over the last decade. Yet there are only a very few systems with natural interfaces such as with speech and gestures. This thesis here addresses the topic of gesture recognition using a 2D camera and how they can be used as natural interfaces to control applications. The gesture recognition algorithm can identify six different gestures and was first developed in a PC and later moved to an embedded platform. A robust background subtraction technique is designed to obtain the hand segment. Two gesture recognition methods are implemented, their performances are measured and the angle-based recognition approach is chosen for its accuracy. The application is moved to an embedded platform i.MX515EVK based on ARM Cortex-A8 processor. To obtain a frame rate suitable for real-time applications, optimizations such as camera capture time reduction, algorithmic optimizations and utilizing SIMD unit of the Cortex-A8 processor known as NEON for data parallelism are performed. As experimentation, the optimized version of the algorithm is used to build a real-time application that recognizes gesture from images to control applications. The performance of the application is studied and a frame rate of 4 - 4.5 frames per second is achieved.
Clarifying the Meaning of Sustainable Business

While sustainability management is becoming more widespread among major companies, the impact of their activities does not reflect in studies monitoring the state of the planet. What results from this is a “big disconnect. ” With this article, we address two main questions: “How can business make an effective contribution to addressing the sustainability challenges we are facing? ” and “When is business truly sustainable? ” In a time when more and more corporations claim to manage sustainably, we need to distinguish between those companies that contribute effectively to sustainability and those that do not. We provide an answer by clarifying the meaning of business sustainability. We review established approaches and develop a typology of business sustainability with a focus on effective contributions for sustainable development. This typology ranges from Business Sustainability 1.0 (Refined Shareholder Value Management) to Business Sustainability 2.0 (Managing for the Triple Bottom Line) and to Business Sustainability 3.0 (True Sustainability).
FACTORS AFFECTING KNOWLEDGE AND ATTITUDE LEVELS OF ARABIC MOTHERS RELATED TO EARLY CHILDHOOD CARIES IN KLANG VALLEY

ABSTRACT Background: Early Childhood Caries (ECC) refers to rampant dental caries in pre-school children. It can affect the child both physically and psychologically. Many factors can affect knowledge and attitude of mothers regarding preventing ECC. The objective is to study the knowledge and attitude of the associated factors of ECC of Arabic mothers of preschool and primary school children in Arabic schools that are registered in the Ministry of Education in Klang Valley in Malaysia. Materials and Methods: A cross sectional study was conducted among 518 Arabic children’s mothers using validated and reliable questionnaire. Simple random technique was used. Data was analysed by using Chi-square and logistic regression. Result: Level of good knowledge on ECC was 49.1% and positive attitude level was 46.6%. The predictors of good knowledge on ECC were respondents with > 4 children (AOR=3.386; 95% CI: 1.779-6.447), have no fears originating from community believes (AOR=1.575; 95% CI: 1.000-2.480), have no fears of extraction (AOR=2.845; 95% CI: 1.443-5.608), and brush twice daily (AOR=1.989; 95% CI: 1.266-3.126). Predictors of positive attitude were respondents with post graduate level (AOR=2.024; 95% CI: 1.287-3.184), attended education program (AOR=2.444; 95% CI: 1.325- 4.506), and have good knowledge level (AOR=2.479; 95% CI: 1.600-3.843). No fears originating from community believe was a protective factor (AOR=0.575; 95% CI: 0.369-0.896). Conclusion: Preventive programs should target vulnerable mothers who are 35 years old or less, have bachelor degree or less, have four children or less, haven’t attended any infant oral health education program and have dental fears. Keywords: Caries, Knowledge. Attitude, Arabic, Mothers, Children, Malaysia
STATISTICAL DOWNSCALING HADCM3 MODEL FOR DETECTION AND PERDICTION OF SEASONAL CLIMATIC VARIATIONS (CASE STUDY: KHABR RANGELAND, KERMAN, IRAN)

Rangelands are one of the most vulnerable parts concerning the climatechanges‟ impacts. These impacts are even stronger in the arid and semi-arid areas whererangeland ecosystems are in critical conditions. Therefore, it is crucial to figure out theactual dynamics of climate variations on the rangelands. The aim of this research was todetermine climate changes in Khabr rangeland, Kerman, Iran. So, four meteorological datasets of HadCM3 model including minimum and maximum temperature, precipitation andradiation rates were used to assess climate changes in the region. In this regard, climatechanges during 2011-2039 were assessed by downscaling HadCM3 data using LARS-WGmodel under three scenarios of B1, A2 and A1B. The results have showed that the rainfallrates of spring and summer would have declining trends under all three scenarios.Minimum and maximum temperature rates would increase in all seasons, and just radiationone showed a decreasing trend for winter. Based on A1B scenario, minimum andmaximum temperature rates had the highest increasing trend. Radiation and precipitationhad the highest increasing and declining trends in the A2 scenario, respectively. Moreover,the increase in maximum and minimum temperature rates was averagely greater than thepast and consequently despite the increasing trend in minimum and maximum temperaturerates, the increase in the mean temperature rate during this period would be expected.According to the results, Khabr rangeland‟s climatic conditions will be significantlydifferent in the next 30 years and long-term and strategic planning is necessary inconsistent with the management policies with these conditions.
A Comparative Study of the Relationship between Mobile Phone Use and Social Capital among College Students in Shanghai and Taipei

This study examines the relationship between motivations for mobile phone use and social capital among mobile phone-savvy college students in Shanghai and Taipei. Our findings from the survey of 1,923 reveal some key differences. Specifically, the Shanghai respondents had a higher motivation for using the mobile phone for entertainment/relaxation and surveillance. Regarding the relationship between motivations for mobile phone use and social capital, results of multivariate analyses using the Shanghai sample show that entertainment and relaxation needs significantly predicted life satisfaction, while surveillance needs were significantly associated with leisure activity. In the Taipei sample, entertainment and relaxation needs significantly predicted leisure activity and life satisfaction. Finally the role of societal factors in accounting for these differences is discussed.
Influence of nanomorphology on the photovoltaic action of polymer–fullerene composites

Composites of conjugated poly(3-hexylthiophene) (P3HT) and the fullerene derivative [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) demonstrate an efficient photogeneration of mobile charge carriers. Thermal annealing of P3HT:PCBM based devices gives rise to a significant increase of the photovoltaic efficiency, as follows from measurements of the external quantum efficiency and the current-voltage characteristics. Upon annealing, the absorption spectrum of the P3HT:PCBM composite undergoes a strong modification, whereas in the pure components it remains unchanged. The absorption of the annealed blends becomes stronger and red shifted in the wavelength region ascribed to P3HT, while the absorption due to the PCBM contribution does not change. Atomic force microscope measurements on P3HT:PCBM disclose some variation in morphology due to the crystallization of PCBM. The concentration of the PCBM clusters and their size (up to 500 nm) were found to be correlated with the amount of PCBM in the blend. We have studied the performance of photovoltaic devices with different weight ratios of P3HT:PCBM, namely, 1:3, 1:2, 1:1.5, 1:1, 1:0.9, 1:0.8, and 1:0.7. The photocurrent and the power conversion efficiency showed a maximum between 1:1 and 1:0.9. We conclude the variation in the absorption spectrum and the red shift to result from molecular diffusion of PCBM out of the polymer matrix upon annealing. The growth of the PCBM clusters leads to formation of percolation paths and, therefore, improves the photocurrent. Above a certain concentration, the PCBM crystals provide mechanical stress on the metal electrode, therefore possibly damaging the interface. Optimization of the composite weight ratio reveals the important role played by morphology for the transport properties of bulk heterojunction P3HT:PCBM based solar cells.
