People have invented different solutions to find out the location of a person or an object on the earth. In the beginning, mariners used angular measurements to calculate their location for celestial bodies such as the sun and stars. In the earlier 1920s, implemented a more sophisticated radio navigation scheme depends on radio waves that give access to the navigators to determine the direction of the transmitters. Soon after, the advancement of satellites made it achievable to transmit with high accuracy, line of sight radio navigation signals created a new era in the technology of navigation. To find the position of an object, a 2-dimensional navigation system called transit was used in olden days. This method was to set the basic building blocks to introduce the global positioning system. This new GPS concept provided outstanding innovative methods to find the position of an object to the public, scientists, military, etc. The predominantly GPS known as Global Positioning System is a range-based positioning system that yields an obscure object's 3D position on top of the earth. This system collects estimates or range data from realized emanating sources to determine the position of obscure objects and the system is also called as a positioning system based on satellites. The precision of the object location frequently relies on the error of the satellite clock, atmospheric delays, multipath, positioning of the satellite, noise and multiple parameters of the receiver. Mostly, none of the above parameters have consistent behavior worldwide and should be checked to provide an exact solution. This paper mainly focuses on the study of GPS evolution, error sources, popular accuracy measures and positioning services of GPS.

Cost of construction of bridges is predicted using multiple linear regression model, based on data of bridges from Maharashtra state in India. Cost per unit area is taken as an appropriate dependent variable. Using both conventional and double log regression techniques, models for cost/m2 and log of cost/m2 are developed. Total 6 independent variables, which include both qualitative and quantitative variables, are used to develop the model. Height of bridge, average span length and depth of foundation are used as quantitative variables. Zone of construction, deck type and foundation type are used as qualitative variables in developing model. Strength of these independent variables with dependent variable is found out using pearson’s correlation method. Model is then verified using Leave One Out Cross Validation (LOOCV) technique. The most suited regression model obtained from the data experiment is double log regression with R2 of 0.850 and a Mean Absolute Percentage Error (MAPE) of 17.74%, as compared to 25% MAPE observed in past for studies related to traditional cost prediction.

Multiple Input Multiple Output (MIMO) is an attractive air interface solution which is used in the 4th generation wireless networks to achieve higher data rate. With a very large antenna array in Massive MIMO the capacity will increase drastically. In this paper channel capacity comparison for MIMO using known Channel State Information (CSI) and unknown CSI has been carried out for a higher number of antennas at transmitter and receiver side. It has shown that at lower SNR known CSI will give better performance compared to unknown CSI. At higher SNR known CSI and unknown CSI will provide similar results. Capacity comparison has been evaluated with help of MATLAB for known CSI and unknown CSI from a small number of antennas to hundred of antennas. Also, the performance evaluated with MATLAB simulation of linear detectors zero-forcing (ZF) and maximum ratio combining (MRC) method for large number of antennas at Base station (BS) which are serving a small number of single antenna users. Performance is evaluated in terms of Symbol Error Rate (SER) for ZF and MRC, and results show that ZF will outperform MRC. It has also been analyzed that increasing the antennas at BS for a small number of users will also help to reduce SER.

Varieties in malleable and sway properties of Roselle fiber strengthened polyester composites brought about by the expansion of glass fiber have been broke down. Roselle fiber in blend with glass is great for making financially savvy composite materials. The impact of the game plan of glass and Roselle fiber in the arrangement of composites have additionally been considered. A volume portion of 0.12 glass blended with Roselle fiber gives 55.5 % expansion in the elasticity and 194 % expansion in the effect quality of the composites. The elasticity demonstrates the most noteworthy worth when a glass volume part of 0.14 is utilized and an interleaving course of action of glass and Roselle fiber is pursued. Be that as it may, when lower volume division of glass is utilized, a cozy blend of Roselle fiber and glass demonstrates the most astounding elasticity.

Sheet Moulding Composite (SMC) is used in automotive body’s for weight & tool cost reduction instead of sheet metal. As an alternative material SMC must fulfill the strength requirement as well as contribute less weight to Body-in-white (BIW). Hence, its mechanical properties & thickness selection must be done strategically. Further bending test setup has to be created & tested by FE analysis and followed by lab testing as a part of validation. Sheet moulding compounds (SMC) are fiber-reinforced thermosetting products. SMC is a generic term of different types of compounds together with the process to convert them into large composite parts by compression molding. SMC are widely used in the sectors like aerospace, agricultural, rail, marine, electrical and energy construction but the automotive and truck industries remain the drivers of SMC technology

This paper discusses about various methods involved in detection of avian pox in the birds using images. Digital images are corrupted while sending and receiving the images because of noisy sensors which degrade the quality of image. Pre-processing becomes an initial and crucial step in image processing to remove the noise and maintain fine details and texture of the image. Pre-processed images can be used for further work. Mean, Median, Weiner, Mean Maximum, Mean Minimum filters are used and performance tests are made using Signal Noise Ratio. Based on the performance test, removal of impulse noise is well done by Median filter and produces the best result when compared to other filters. K-Means clustering and SVM are used for identification of the disease.

Spanwise flow corrections for tidal turbines
Authors: Wimshurst A. , Willden R.
Published: November 2019

Actuator line computations of two different tidal turbine rotor designs are presented over a range of tip speed ratios. To account for the reduction in blade loading on the outboard sections of these rotor designs, a spanwise flow correction is applied. This spanwise flow correction is a modified version of the correction factor of Shen et al. (Wind Energy 2005; 8: 457-475) which was originally developed for wind turbine rotors at high tip speed ratios. The modified correction is described as ‘directionally dependent’ in that it allows a more aggressive reduction in the tangential (torque producing) direction than the axial (thrust producing) direction and hence allows the sectional force vector to rotate away from the rotor plane (towards the streamwise direction). When using the modified correction factor, the actuator line computations show a significant improvement in the accuracy of prediction of the rotor thrust and torque, when compared to similar actuator line computations that do not allow the sectional force vector to rotate. Furthermore, the rotation of the sectional force vector is attributed to the changing surface pressure distribution on the outboard sections of the blade, which arises from the spanwise flow along the blade. The rotation of the sectional force vector can also be used to explain the reduction in sectional lift coefficient and increase in sectional drag coefficient that has been observed on the outboard blade sections of several rotors in the literature
Winter and summer differences in probability of fish encounter (spatial overlap) with MHK devices
Authors: Viehman H. , Boucher T. , Redden A.
Published: November 2019

The likelihood of fish encountering an MHK device, and therefore the risk posed to fish, depends largely on the natural distribution of fish at tidal energy development sites. In temperate locations, such as the Bay of Fundy, seasonal changes in the environment and fish assemblage may alter the likelihood of fish encounters with MHK devices. We examined two one-month hydroacoustic datasets collected in winter 2015 and summer 2016 by an upward-facing echosounder deployed at the Fundy Ocean Research Center for Energy test site in the Minas Passage. Fish density was higher and less variable in winter than in summer, likely due to the presence of migratory vs. overwintering fish. The vertical distribution of fish varied with sample period, diel stage, and tidal stage. The proportion of fish at MHK device depth was greater, but more variable, in summer than in winter. Encounter probability, or potential for spatial overlap of fish with an MHK device, was < 0.002 for winter and summer vertical distributions. More information on the distribution of fish (horizontal and vertical), species present, fish sensory and locomotory abilities, and nearfield behaviours in response to MHK devices is needed to improve our understanding of likely device effects on fish.
Adapting conventional tools to analyse ducted and open centre tidal stream turbines
Authors: Allsop S. , Peyrard C. , Bousseau P. , Thies P.
Published: November 2019

This paper details a hydrodynamic model based on Blade Element Momentum Theory (BEMT) developed to assess ’conventional’ 3-bladed tidal stream turbines (TSTs), adapted here to analyse an ’unconventional’ case of a ducted and open centre device. Validations against a more detailed coupled Reynolds averaged computational fluid dynamics (RANS-BEM) model shows excellent agreement, of within 2% up to the peak power condition, with associated computational times in the order of a few minutes on a single core. The paper demonstrates the application of hydrodynamic forces into a structural analysis tool, in order to assess blade stress distributions of a generic hubless turbine. Incorporation of parameters such as non-uniform inflows and blade weight forces are investigated, with their effects on stress profiles presented. Key findings include: i) the adapted BEMT model replicates the majority of turbine performance characteristics estimated through previous CFD assessments; ii) the proposed model reduces the computational effort by several orders of magnitude compared to the reference coupled CFD, making it suitable for engineering assessments iii) blade stress distribution profiles are quantified, detailing concentration zones and cyclic values for use in fatigue analyses. This work forms part of a greater project aimed to develop a suite of analytical tools to perform engineering assessments of bi-directional ducted TSTs.
Tethys knowledge management system: Working to advance the marine renewable energy industry
Authors: Whiting Jonathan , Copping Andrea , Freeman Mikaela , Woodbury Amy
Published: November 2019

Development of the marine renewable energy (MRE) industry has been challenged by uncertainty about potential environmental effects, which has resulted in slowing of permitting/consenting processes, and ultimately to constraints on the industry. These challenges result from a lack of sufficient devices in the water from which to learn, a dearth of quality monitoring data, and a lack of accessibility to information about these effects in general. This paper describes an ongoing process to improve understanding of the environmental effects of MRE through a public, online knowledge management system funded by the U.S. Department of Energy, known as Tethys (https://tethys.pnnl.gov). Tethys collects and curates relevant documents while supporting a diverse international community through intentional outreach and synthesis activities, which occurs largely through an international collaboration under the IEA Ocean Energy System’s OES-Environmental, formerly known as Annex IV. After nearly ten years of operation, Tethys is internationally recognized and viewed as a trusted broker of information, with over 75,000 visitors annually. Tethys has provided clarity around environmental effects during a critical time in the industry when deployments are increasing in size and frequency.

Apuntes sobre Criminología Feminista
Authors: Durán Moreno Luz María
Published: November 2019

La criminología ha desarrollado un importante trabajo en la explicación de la criminalidad, en el que han confluido principalmente los estudios sobre los hombres delincuentes, desarrollando escasos trabajos sobre la conducta criminal de las mujeres. Es a partir de los años setenta, con la tesis de la liberación que se cuestiona sobre el papel de las diferencias de género en la explicación de las marcadas diferencias en la participación criminal de hombres y mujeres. El interés por este tema permite desarrollar estudios y políticas más enfocados hacia la victimización de las mujeres. En los años noventa inicia una visión alterna que cuestiona la necesidad de abordar este tema, ya no teniendo como punto de referencia la conducta delictiva del varón, sino recurriendo a conceptos y métodos que se encuentran fuera del discurso criminológico, como la perspectiva de género; teniendo presente también la necesidad de los estudios sobre masculinidad.
