Path Attenuation Calculator for Rain Fade
Authors: Abdulhamid Mohanad , Wekesa Waswa 
Published: July 2019

Abstract
Rain as a weather phenomenon is one of the things that greatly affects propagation of radio waves. Above 10 GHz, the attenuation brought about by the interaction of the propagating waves and the rain droplets becomes significant for both terrestrial radio links and satellite links. For this reason, rain attenuation models have been developed to aid in planning purposes for network implementation. The models use statistics to predict the attenuation that is caused by specific amount of rain and also the type of rain. This means that different regions will have different levels of attenuation due to the fact that they experience different types and amount of rain. A couple of models exist including the ITU-R, Moupfouma model, Crane attenuation model and other localized models depending on the geographical area that research data collection and extensive analysis has been conducted on and a comprehensive set of values and factors have been determined that can aid in estimation of attenuation due to rain. This paper seeks to provide a viable means by which a transmission engineer can be able to know the attenuation per kilometer due to the various models. This is achieved by designing a software calculator that provides the output of the attenuation per kilometer (dB/Km) while taking an input of rain rate for the different models available. The calculator is based on visual basic platform and works with forms.
Solar Energy Conversion Using Low Cost Inverter
Authors: Al-Rawi Muhanned 
Published: July 2019

Abstract
This paper focuses on designing and implementing of an inverter and particularly focuses on developing a low cost transformer-less voltage source conversion that has a higher efficiency as well as compact in size. The complete design consists of DC-DC converter and a DC-AC inverter. The converter is dependent on switched capacitor techniques and steps 12Vdc to 240Vdc. The inverter is dependent on a full-bridge configuration which produces a 240Vac output from 240Vdc. To achieve the improvement in inverter efficiency and a reduction in cost, the power transformer and magnetic components such as inductors are eliminated. In addition, inverter voltage control techniques such as pulse width modulation (PWM) and switching of MOSFETs are optimized through digital control using ATtiny26L microcontroller unit.

Authors: Farhan Mhnd 
Published: July 2019

Abstract
Owing to the increase in the internet traffic, any calculation that requires more than linear time would be considered unreasonably moderate for constant applications. One cure is to utilize numerous processors to build up associations in parallel and the other is to construct low cost, high speed, large capacity non-blocking switching architecture. In this paper, our focus is on developing parallel algorithms for routing which will ensure high-speed internet connectivity and at the same time making the system to be cost effective.
Analisys of Access Points with the Queue Model for Biometric Access Control in Large Headcount Plants
Authors: Otti Csaba , Hanka László 
Published: July 2019

Abstract
The scaling of access control systems is usually done with respect to the life protection requirements regarding escape routes. At large headcount areas, the need for biometric identification arises from the security and business needs. Biometric systems can be characterized by probability variables, which can significantly affect the access process. Mathematically, access control is a discrete state space, stochastic process without memory, that can be described by a queue model. This study demonstrates the process model of access control systems and describes the mathematical model that allows for accurate planning and can ensure a successful introduction for access control systems.
New Aspects Concerning Dynamics of Rigid Solid Body in Plane-Parallel Motion Subjected to Real Constraints. Part One
Authors: Tătaru Vladimir Dragoş , Tătaru Mircea Bogdan 
Published: July 2019

Abstract
The present paper approaches in an original manner the dynamic analysis of a wheel which climbs on an inclined plane under the action of a horizontal force. The wheel rolls and slides in the same time. The two movements, rolling and sliding are considered to be independent of each other. Therefore we are dealing with a solid rigid body with two degrees of freedom. The difficulty of approaching the problem lies in the fact that in the differential equations describing the motion of the solid rigid body are also present the constraint forces and these are unknown. For this reason they must be eliminated from the differential equations of motion. The paper presents as well an original method of the constraint forces elimination.
Do Return Migration Policies Matter? A typology of young Romanian returnees’ attitudes towards return policies
Authors: Șerban Monica , Croitoru Alin 
Published: July 2019

Abstract
During the last decades, the interest in migration policies has increased, both at institutional level and in academia. However, if the scientific understanding of policies associated with migration at destination has tremendously advanced, our knowledge about origin countries interventions in migration stays limited. Our paper addresses one of the largely unexplored topic of this area: if and what kind of policies supporting return/returnees the returnees themselves find appropriate. The analysis is based on 120 interviews with Romanian returnees, aged 18 to 39, coming back after at least 6 months of working or studying abroad in different EU countries. The article reveals that even if the return policies are generally positively evaluated by the Romanian returned migrants, not all of them support the idea of having policies specially designed for attracting migrants back to the origin country. Some of them simply reject the idea and others are sceptical about the state capacity of implementing this type of policies. The paper explores all the main clusters of attitudes towards return migration policies and illustrates each of them with excerpts from in-depth interviews.

Using Gamification and Fear Appeal Instead of Password Strength Meters to Increase Password Entropy
Authors: Rodwald Przemysław 
Published: July 2019

Abstract
It is very common for users to create weak passwords. Currently, the majority of websites deploy password strength meters to provide timely feedback. These meters are in wide use and their effects on the security of passwords have been relatively well studied. In this paper another type of feedback is studied: a gamified approach supported by fear appeal. In this approach, users are encouraged to make passwords stronger through the use of visual and textual stories. This approach is supported by data-driven suggestions about how to improve password security as well as by fear appeal. To prove the effectiveness of this gamified password creation process, an experiment was performed in which users changed their passwords in two ways: without any feed-back, and with gamified feedback with fear appeal. To support the initial findings a questionnaire was completed by participants at the end of research.

Changes in the Logistics System of the Polish Navy
Authors: Jankowski Mariusz 
Published: July 2019

Abstract
The aim of the article is to show the changes taking place in the structures of logistical support of the Polish Navy, focusing on the changes in the way of supplying ships of the Polish Navy. In recent years, the Polish Navy has undergone many changes in the subject matter, starting from the liquidation of the Logistics of the Polish Navy and the Polish Navy Command, including the Management of Logistics Planning. The changes contributed to the centralization of Logistics, creating the Inspectorate for Armed Forces Support of the Republic of Poland, which focused on the main burden of tasks related to, among others, repairs, modernization and supply of ships. On the other hand, it extends the time of issuing opinions on, for example, the protocols for assessing the technical condition of military equipment (ME), which are the basis for the replacement, repair or further exploitation of the ME.
Text Spotting in the Wild with Embedded Device
Authors: Zacniewski Artur , Bodnar Tadeusz 
Published: July 2019

Abstract
Detecting and recognizing text in natural scenes (e.g. streets, restaurants, shops, etc.) could be a part of an artificial intelligence system, especially with regard to the speech synthesis system. Properly detected text is passed to a recognition stage and then to the speech synthesis system, which translates text to speech. Research is carried out for the ‘Toucan Eye’ project — embedded device with artificial intelligence system able to help people with impaired sight. Due to constrained resources and abilities of embedded devices, criteria for text spotting must be met. First criterion is quality of detected and recognized regions with text and the second is time spent on both operations. Particular stages of the system and chosen methods of text spotting under aforementioned constraints are presented.
Green Propulsion Research at TNO the Netherlands
Authors: Mayer Alfons , Wieling Wolter 
Published: July 2019

Abstract
This paper describes the recent theoretical and experimental research by the Netherlands Organisation for Applied Scientific Research (TNO) into green replacements for hydrazine, hydrazine derivatives and nitrogen tetroxide, as propellants for in-space propulsion. The goal of the study was to identify propellants that are capable of outperforming the current propellants for space propulsion and are significantly less hazardous for humans and the environment. Two types of propellants were investigated, being monopropellants and bipropellants. The first section of the paper discusses the propellant selection. Nitromethane was found to be the most promising monopropellant. As bipropellant, a combination of hydrogen peroxide (HP) and ethanol was selected, where the ethanol is rendered hypergolic with hydrogen peroxide. The second part of the paper describes the experimental verification of these propellants by means of engine testing. Initiation of the decomposition of nitromethane was found to be problematic, hypergolic ignition of the hydrogen peroxide and ethanol bipropellant however was successfully demonstrated.

Propulsion System Modelling for Multi-Satellite Missions Performed by Nanosatellites
Authors: Sochacki Mateusz , Narkiewicz Janusz 
Published: July 2019

Abstract
Progress in miniaturization of satellite components allows complex missions to be performed by small spacecraft. Growing interest in the small satellite sector has led to development of standards such as CubeSat, contributing to lower costs of satellite development and increasing their service competitiveness. Small satellites are seen now as a prospective replacement for conventional sized satellites in the future, providing also services for demanding users. New paradigms of multi-satellite missions such as fractionation and federalization also open up new prospects for applications of small platforms.
To perform a comprehensive simulation and analysis of future nanosatellite missions, an adequate propulsion system model must be used. Such model should account for propulsion solutions which can be implemented on nanosatellites and used in multi-satellite missions.
In the paper, concepts of distributed satellite systems (constellations, formations, fractionated and federated) are described with a survey of past, on-going and planned multi-satellite nanosatellites missions. Currently developed propulsion systems are discussed and the models of propulsion systems embedded in the WUT satellite simulation model are presented.
Development and Testing of Data Reduction Software for Measurements Using Pressure Sensitive Paints
Authors: Deitrick William J. , Stryczniewicz Wit 
Published: July 2019

Abstract
The paper concentrates on post-processing of data necessary for pressure measurements using Pressure Sensitive Paints (PSP). The purpose of the study was to develop and test procedures for extraction of the surface pressure distribution from the images captured during PSP tests. The core issues addressed were reduction of the influence of model movement and deformation during wind tunnel run and synchronization between conventional pressure tap measurements and PSP data, necessary for in-situ calibration. In the course of the studies, two approaches on image registration were proposed: the first based on geometric transformation of control points pairs with cross-correlation tuning and the second based on similarity finding and estimation of geometric transformation of the images. Performance of the developed algorithm was tested with use of experimental set-up allowing for controlled movement of the imagined target with micrometer resolution. Both of the proposed approaches to PSP image resection proved to perform well. After testing of the software, the PSP system was used for determination of the pressure field on flat plate exposed to impinging jet. The presented procedures and results can be useful for research groups developing in-house PSP measurements systems for wind tunnel tests and internal flow investigations.

Published: July 2019

Permasalahan utama yang dihadapi rumah tangga pelaku industri kecil dan menengah (IKM) batubata pada umumnya adalah frekuensi penerimaan yang tidak stabil dan cenderung dengan frekuensi waktu cukup panjang. Proses produksi batubata mulai dari penggalian tanah sampai siap jual membutuhkan waktu relatif cukup lama dan bahkan bulanan. Tujuan utama kegiatan adalah memperkuat daya tahan ekonomi rumah tangga pelaku IKM Batubata melalui diversifikasi usaha budidaya Jamur Tiram. Kegiatan menggunakan Pendekatan Partisipatif (Participatory Rural Appraisal) dengan Sistem Modal Bergulir Internal (Internal Revolving Capital System). Program penguatan daya tahan ekonomi rumah tangga pelaku IKM Batubata ini masih pada tahap pengenalan sehingga ruang lingkup kegiatan untuk sementara masih terbatas aspek budidaya. Pengembangan lanjutan pada masa akan datang akan mengarah ke sektor hulu (pembuatan baglot sebagai input primer dan sektor hilir berupa industri pengolahan hasil pasca panen. Program lanjutan pada masing-masing kelompok sasaran akan menggunakan sumberdana lain dan sangat tergantung pada motivasi dan keberhasilan program budidaya jamur tiram. Pelaksanaan kegiatan dilakukan melalui 4 (empat) tahapan yaitu tahapan persiapan, budidaya dan perguliran modal kelompok serta pelaporan. Berdasarkan evaluasi terhadap hasil kegiatan dengan berbagai kendala teknis dan non-teknis yang dihadapi selama proses pelaksanaan, maka dapat disimpulkan bahwa program pengabdian kepada masyarakat ini belum memberikan hasil optimal bagi penguatan ekonomi rumah tangga dan usaha kelompok pengrajin batubata rakyat. Meskipun demikian, model pengembangan kumbung diatas kolam bekas galian (KBG) telah mampu menarik motivasi rumah tangga untuk memanfaatkan KBG mereka. Program ini telah menjadi embryo dan layak untuk ditindaklanjuti melalui program lainnya baik dalam bentuk riset (peneltiian) maupun pemberdayaan masyarakat.
