Design and Development of an Unmanned Surveillance Aerial Vehicle ( USAV ) Using Locally Sourced Materials

An Unmanned Surveillance Aerial Vehicle (USAV) is an air vehicle which is largely used for surveillance, monitoring, reconnaissance, data relay, and data collection or to enter an area which is not safe for human. This study documents the development and evaluation of a low cost, short range unmanned aerial vehicle to monitor a fixed operational urban area. Aerodynamic principles were employed to develop a better concept through reasonable design considerations and assumptions. The design was then modeled using National Aeronautics and Space Administration (NASA) Vehicle Sketch Pad (VSP). Analysis of aerodynamic properties of the wing airfoil section, lift and drag analysis of resisting surfaces, stability in flight were carried out with the aid of Computational Fluid dynamics software (JAVA FOIL). Ultimately, in achieving the goal of this study, the design concept was supported by the fabrication of a flying prototype.
INDUSTRIAL SIMULATION OF LIQUID RESIN INFUSION BY THE FINITE ELEMENT METHOD

With the increasing use of composite materials in the aerospace industry, composite parts suppliers show a growing interest about process simulation. Among the industrial processes used in the production phase, resin infusion appears more and more as an economical alternative for manufacturing large parts with an important fiber fraction (wind turbine blade, aircraft wing.). However, the lack of control on the final properties of the part, implying long and expensive process tuning, significantly reduces the above-mentioned advantages. So, a full model coupling fluid/solid/porous mechanics is proposed to simulate the liquid resin infusion (LRI) process, in order to anticipate the potential problems numerically.
Anomaly Detection from System Logs based on Spectral Method

This research provides a statistical method for detecting anomaly using multivariate data from system metrics. The spectral anomaly detection technique has been implemented using PCA (Principal Component Analysis) as unsupervised method to detect anomaly from data consisting of both normal and abnormal events. A comparison has been done with another unsupervised algorithms namely K-means which shows PCA outperformed K-means by 30% when F-measure is used to evaluate for probe attacks for standard DARPA (Defense Advanced Research Projects Agency) dataset. The real data of the system has been collected and analyzed using unsupervised approaches for detecting anomalies. Also, the results of real data have been validated with visual plots. The result shows PCA as a better way to find the anomalous events and detect them precisely. Keywords—System, multivariate data, DARPA, Anomaly Detection, K-means, PCC, CART.
The Structures of Hydrazine Crystal and Its Antibacterial Activities

The crystal of 1, 2-bis (ethoxycarbonyl) hydrazine was studied by XRD, FTIR and Raman spectroscopy. The ground-state geometries were optimized at B3LYP/6-31+G (d, p) level. These vibrational wavenumbers were calculated at the same level. The antibacterial activities have been screened for the compound against two bacteria: Staphylococcus aureus and Escherichia coli.
A person identi fi cation method using facial , clothing and time features

In this paper, we propose a method for personal identification using facial features and context information. The method can overcome a problem of partially occluded images. In the proposal method, facial similarity is calculated by using the CLAFIC method from a face image and the parts in the face, such as the image of eyes. In addition, we focus on clothes of each target person and time information as the context. We apply these features into a scoring method and a machine learning method. In the experiments, we confirmed that proposal method is better than the method using only the face image similarity and the heuristic method based on a scoring.
reparation of Au n quantum clusters with catalytic activity in-cyclodextrin polyurethane nanosponges iego

Here we report the use of -cyclodextrin polyurethane nanosponges cross-linked with 1,6hexamethylene diisocyanate as a template for the preparation of Aun quantum clusters, by the core-etching of glutathione-capped Au nanoparticles. The study of temporal evolution of the core-etching process using different Au concentrations indicated that formation of Aun clusters embedded in the nanosponge is favored by the use of lower Au concentrations, since it began at shorter times and lead to higher cluster loading. An estimation of the number of Au atoms based on the maximum photoluyclodextrin polyurethane
Power System loss minimization by using UPFC placed at optimal location given by Artificial Bee Colony Algorithm

In this paper, heuristic technique based minimization of losses in the power system using Unified Power Flow Controller is proposed. Here, the Artificial Bee Colony Algorithm (ABC) optimizes the location of the UPFC, while the generator outage occurs. The optimum location is referred as the maximum power loss bus, because the generator outage affects the power flow constraints like power loss, voltage magnitude, real and reactive power. By using UPFC at the optimum location minimum power loss is attained. Then UPFC is placed in the optimum location and the corresponding results are analyzed. The proposed method is implemented in the MATLAB/Simulink platform and the performance is evaluated by using the comparison power loss at different conditions. The comparison results demonstrate the superiority of the proposed approach and confirm its potential to solve the problem. Index words: UPFC, ABC, power loss, power flows.
Ownership structure , liquidity , and trade informativeness

In this paper, we examine the relationship between ownership structure (or number of financial analysts following) and liquidity and trade informativeness. We find that insider ownership is negatively correlated with liquidity after controlling for price, volatility, trading volume, and market capitalization. In addition, stocks with higher institutional ownership or larger number of financial analysts following have better liquidity. Furthermore, we find a stock with higher insider and institutional ownership has higher informativeness of trades. These results imply that there is more informed trading for stocks with higher insider and institutional ownership, and market makers believe that insiders and institutional investors are informed traders.

The progressive postharvest disorder of ‘Nules Clementine’ mandarin (Citrus reticulata Blanco), referred to as rind breakdown (RBD), starts to develop during storage, about 3–5 weeks after harvest. Variation within the tree canopy, i.e. inside or outside canopy positions, as well as postharvest handling practices such as ethylene degreening, storage temperature and storage duration, were investigated for their influence on RBD incidence. Two experiments were conducted wherein fruit were subjected, in the first experiment, to ethylene degreening and a delay in commencement of cold storage (2004), and, in the second experiment, fruit were sampled from the inside and outside of the canopy and cold-stored at either −0.5 ◦C or 7.5 ◦C during 2005 and 2007. Rind pigment and carbohydrate contents as well as rind colour and RBD incidence were recorded during prolonged storage. The senescence-promoting treatments resulted in an increase in RBD incidence, except for storage at −0.5 ◦C, which resulted in a lower occurrence of RBD. Overall, results indicated that the incidence of RBD was aggravated by senescence-promoting factors during the postharvest handling of fruit and this is thought to lead to the premature senescence of the flavedo. In addition, fruit position in the tree canopy during fruit development contributed significantly to RBD sensitivity, with inside fruit having significantly higher RBD incidence compared to outside fruit. © 2011 Elsevier B.V.

High-speed video observation of bidirectional leader whose negative end contacted ground and produced a return stroke

A bidirectional leader, the negative end of which contacted ground, was observed at the Lightning Observatory in Gainesville, Florida, on 2 August 2014. The bidirectional leader developed during the late stage of a cloud discharge and appeared to be initiated in a decayed (not luminous for at least 43 ms) channel of the latter. The leader extended bidirectionally in virgin air for at least 12 ms with both ends branching. After turning toward ground, its negative end exhibited features characteristic of preliminary breakdown and stepped leader of first negative cloud-to-ground strokes, while the positive end most of the time remained almost stationary or showed rapid extensions followed by retractions. The development of positive end involved a very bright process that caused abrupt creation of 1-km long, relatively straight branch, forked at its far end. The bidirectional leader connected, via its positive end, to another considerably longer bidirectional leader (floating channel) to form a larger bidirectional leader, whose negative end attached to the ground and produced a 36-kA return stroke.
New approaches using genetic material as a control to tuberculosis

Messenger RNA (mRNA) is highly versatile, non-toxic molecule that is easy to produce and store, which can allow transient protein expression in all cell types. The safety aspects of mRNA-based treatments in gene therapy make this molecule one of the most promising active components of therapeutic or prophylactic methods. The use of mRNA as strategy for the stimulation of the immune system has been used mainly in current strategies for the cancer treatment but until now there is no tested mRNA as vaccine for infectious disease. We produced mRNA of heat shock protein of 65-kDa (Hsp65) from Mycobacterium leprae and showed that vaccination of mice with a single dose of 10 μg of naked mRNA-Hsp65 through intranasal route was able to induce protection against subsequent challenge with virulent strain of M. tuberculosis. In order to determine if antigen-presenting cells present in the lung are capable of capture the mRNA, labelled mRNAHsp65 was administered by intranasal route and then lung APCs were analyzed by flow cytometry. These experiments showed that after 30 minutes until 8 hours the populations of CD11c, CD11b and CD19 cells were able to capture the mRNA. Taken together, our results showed a novel and promise strategy to control experimental tuberculosis. Key-Words: mRNA, Hsp65, Tuberculosis, Vaccine, Antigen-presenting cells, pcDNA3-Hsp65.
ON THE INTERACTION OF SEPARATION BUBBLES IN THE NEAR WAKE OF A CYLINDER

Two dimensional numerical simulation of laminar flow around a confined cylinder with parallel slit is carried out using openFoam. Five different slit widths with non-dimensional separation ratio of 0, 0.05, 0.1, 0.15, and 0.2 are chosen to study the effect on vortex formation mechanism. The interesting feature of this configuration is the emergence of separation bubbles from the slit. At lower slit widths the characteristics of the flow and vortex formation mechanism is similar to the flow over a solid-confined cylinder. At higher slit width (s > 0.15d), a separation bubble from each of the inner surface is formed and they oscillate in same phase. The favorable condition for the formation of the separation bubble (i.e. at Reynolds number and slit width) is identified by calculating the phase difference of velocity signal at each separation points of the bluff body. For s/d=0.05 and 0.1 separation bubble is not observed for all Reynolds numbers simulated. At s/d=0.15 and Re=200 the formation of separation bubble starts and becomes significant as Re increases. For s/d=0.2 the separation bubble is observed for Re=300 and 400. The strength of the primary or outer vortex is found to be affected by the interaction of the separation bubble. Maximum value of Γ (normalized strength of outer vortex) is observed at s/d=0 and Re=400 which is 0.65. At Re=400, Γ value for s/d=0.2 is 0.525. The slit width is seen to be an important parameter in determining the strength of the primary vortex and separation bubble. The vortex shedding frequency of the bluff body is greatly affected by the formation of the separation bubble. Such kind of vortex formation mechanism due to the formation and interaction of the separation bubble can be utilized to improve the performance of various practical applications such as vortex flow meter, heat exchangers etc. NOMENCLATURE s: Slit width (m) d: Diameter of cylinder (m) H: Height of the channel (m) Y: Radial distance (m) β : Blockage ratio (d/H) θ: Angle between axis and line joining any point in the circumference of cylinder to center of cylinder measured in clockwise direction for upper half of cylinder(degrees) L: Length of the channel (m) LH: Length in horizontal direction (m) LV: Projected length in vertical direction (m) Um: Mean velocity (m/s) Uc : Centerline velocity(m/s) f : Frequency of vortex shedding ρ: Density of fluid (kg/m) μ: Dynamic viscosity of fluid (Pa s) Γ: Circulation strength of vortex core (m/s) Γ: Normalized circulation strength of outer vortex core
INVESTIGATOR DISTURBANCE AND CLUTCH PREDATION IN WILLOW PTARMIGAN : METHODS FOR EVALUATING IMPACT

--The possible effect of investigator disturbance on clutch predation in two populations of Willow Ptarmigan (Lagopus lagopus) was investigated using three different techniques. No significant difference was found in (1) the proportion of hens that succeeded in producing broods for hens whose nests were found vs. those that were not located, (2) proportion of broodless hens on an intensively studied area vs. an area that was not studied, (3) the proximity of nest flags for successful vs. depredated nests. A new technique was developed to compare rates of visits and types of nest checks between successful and depredated nests. This method controlled for period under observation and stage of breeding. Methods for minimizing investigator disturbance are discussed.

Patterns and levels of clutch predation are important in avian studies of life history traits (e.g., Perrins 1977, Slagsvoid 1982) and population regulation (e.g., Bergerud et al. 1985). The techniques used to monitor nesting birds, however, may alter the natural rate of clutch predation; hence the results may not be independent of how they were obtained (Lenington 1979). This problem is not uncommon; in a recent review, Gi3tmark (1992) found that 39 of 78 studies that considered investigator disturbance reported a significant (? < 0.05) effect on clutch predation or overall nesting success. The direction and magnitude of potential disturbance by human activities will differ from study to study depending upon the ecology of the • Current address: Canachan Wildlife Serwce, Paczfic and Yukon Region, P.O.

Phenotypic studies on Wheat and Barley after colonization with mycorrhiza symbiosis Fungi

Symbiotic associations between endomycorrhiza and crops can provide several benefits to the host crops. An investigation was conducted to assess the impact of arbuscular mycorrhizal fungi (AMF) inoculation on seed germination, overall growth (growth rate and percentage) and the general morphology of barley and wheat plants. The experiment demonstrated that the height was significantly higher in barley plants grown in soil inoculated with AMF (45.0±1.6 cm versus 30.8±0.9 cm for those grown in non-inoculated soil; p=0.014). Similarly, stem and root length were significantly higher in barley plants grown in AMF-inoculated soil (p=0.009 and 0.04, respectively). Further, dry shoots of plants grown in AMF-inoculated soil weighed significantly more than those grown in non-inoculated soil (1.020±0.015 g versus 0.353±0.015 g for plants grown in non-inoculated soil; p=0.002). The dry shoots and dry roots of barley plants grown in AMF-inoculated soil weighed significantly more than those of plants grown in non-inoculated soil (p=0.0006 and 0.009, respectively). Both the growth rate and percentage were increased in AMF-inoculated wheat plants. A similar increase in growth rate was observed in barley plants inoculated with AMF (P<0.005). Overall, inoculation with AMF was beneficial in increasing plant growth parameters and plant biomass.
Detection of Weather Anomalies and Events of Interest Using Complex Event Processing

Detection of weather conditions is of prime importance, as it directly affects day-to-day life. Several meteorological variables are used to measure the current state of the atmosphere at a given location and time. These meteorological variables are useful in determining both short and long-term changes in the atmosphere. However, this is quite challenging as it requires real-time data collection, transmission, and processing. Further, it is important to identify anomalies in the sensor data such as missing or incorrect readings from weather stations. This research aims at detection of these weather anomalies and events of interest using Complex Event Processing (CEP).
APPLICATION OF ARCHETYPE ENGINEERING MODELING TO ESTIMATE HOURLY ELECTRICITY DEMAND OF COMMERCIAL SECTOR OF KEIHANSHIN METROPOLITAN AREA , JAPAN

This paper presents an application of the archetype engineering modelling approach to the commercial building stock in the Keihanshin metropolitan area, Japan. This application especially focused on hourly electricity demand. The calculated peak electricity demand in August was estimated to be 11.1 GW and the time-varying characteristics was well modelled. However, the peak electricity demand was underestimated by 1.0 GW because not all building stock was covered in the model. Electricity demand during night was also underestimated by 1.5 GW, implied that more survey is needed on how people use commercial buildings and how building space and equipment is operated.
Spectral Improvement of Time Resolved PIV by FTEE in Homogeneous Isotropic Turbulence

This work investigates the performance of the time-resolved PIV technique FTEE with an optimized 2-Frame PIV algorithm on both synthetically generated and experimentally measured homogeneous isotropic turbulence (HIT). In the case of the synthetic tests, the algorithms are compared with a model that appropriately filters the full resolution HIT to replicate a perfect PIV treatment. Several turbulence quantities are computed such as turbulent kinetic energy, energy dissipation and integral length scale for both the experimental and synthetic experiments. Calculation of the energy spectra was carried out to analyse the algorithm’s ability to resolve turbulent scales. It is shown that FTEE algorithm is able to resolve smaller scale structures by virtue of its ability to reduce the interrogation window (IW) size compared to the 2-frame algorithms. This is mainly owing to the ensemble cross correlation of the cross-correlation maps that permits lower particle numbers in the IW and the modilisation of trajectories by a non-linear polynomial.

Role of shirodhara with ashwagandha taila in management of stress induced insomnia

Ayurveda has considered sleep as one of the most important dimensions of health associated with happiness and good health. The man of 21 century is breathing under various stresses, strain, anxiety and irregular and unnatural food habits so insomnia is a very common sleep disorder stressful life event are closely associated with the onset of insomnia and are mediated by certain predisposing personality factors. Shirodhara is used popularly for the headache, nervous disorder, stress, insomnia, and hypertension etc. Shirodhara is based on the principle of invigorating the mind bringing on essence in the body. Shirodhara works on the forehead and calming the nerves. It also help to enhance blood circulation to the brain & there by helps to beat insomnia and calms the mind and body. A clinical study on 20 cases of insomnia was done to evaluate the efficacy of shirodhara with ashwagandha taila (sesame oil processed with ashwagandha – Withania somnifera). In their treatment the efficacy was evaluated on the basis of characteristics of sleeplessness, sleep awake schedule, sleep quality, sleep time, feeling after awakening and associated symptoms. The effect of therapy was also evaluated at DASS scale. The overall result of this measure is work encouraging and significantly effective.
Numerical Modeling of EHD-Induced Liquid Extraction in a Cylindrical Electrode Configuration

A comparison of modeling techniques for two-dimensional, adiabatic liquid extraction under an applied voltage is investigated. High voltage is applied to a central cylindrical electrode and the outer surface is grounded. The dielectric fluid is assumed to have negligible free charges and therefore only the dielectrophoretic and electrostrictive force components of the electric body force are considered. The modeling techniques compared in this paper use existing commercial code with user defined functionality to account for the interfacial forces. The main variables affecting the interfacial forces, and therefore the extraction times, are highly dependent on the treatment of the interface and the inclusion of surface tension effects. Methods which use a finite-thickness interface underestimate the interfacial force, stretch the interface and thus, overestimate of the extraction times, however these methods are currently more robust and can handle complex geometries. Methods which use a zero thickness interface result in more accurate interfacial forces but are limited to simple geometries with moderate mesh deformation and are affected by interface curvature approximation issues that affect surface tension. Keywords—Liquid extraction, numerical modeling, Maxwell stress tensor, electric body force, interfacial stress
