Near-Field Direct Antenna Modulation (NFDAM) transmitter at 2.4GHz

A near-field direct antenna modulation (NFDAM) transmitter at 2.4GHz is demonstrated on a microstrip setting. The transmitter is capable of transmitting information in a direction-dependent fashion by sending the correct signal constellation only in the desired direction while leaving the signal constellation points scrambled in undesired directions. This direction-dependent constellation scrambling nature of the NFDAM systems prevents undesired receivers to correctly demodulate the signal transmitted to a desired receiver at a specific direction

Educational reform in Nigeria: the case of Multicultural Education for Peace, Love, and Tolerance

The cohesion of our multicultural societies depends on mutual understanding, engaging proactively in co-operation between different communities and respecting one another. This paper deals with the educational philosophy of a well-known Turkish Islamic scholar, Fethullah Gülen and its application to schools in Nigeria. Gülen- inspired schools in Nigeria are peace islands in the ocean of violence, and promote love, greater empathy, tolerance and peace in a society deeply divided along ethnic, religious, tribal and geographical lines. Following Gülen’s example, the schools promote respect for other cultures and the trains of thought of various well-known scholars. Students, throughout their education, learn to appreciate other faiths, ethnicities and cultures, as well as their own. This article reports on a 2010 qualitative field study conducted at the Nigerian Turkish International Colleges (NTICs) in Abuja, Nigeria. In this qualitative inquiry, the researchers used observations, in- depth individual interviews and focus groups to elicit the lived experience of four identified groups of stakeholders (administrators, teachers, students and parents). Participants in this study comprised 22 adults, of which 9 were females and 13 males, aged 16 to 61 ( M = 28.9). The findings indicate that the Gülenian style of education, as it is implemented in Nigeria, and according to the reflectionsof those participants involved with NTICs, exposes students to people from different parts of Nigeria, as well as people who often are from different ethnic, religious and socio-economic backgrounds. The organisation of the school and the school activities allow students to experience those differences in a safe setting, resulting in their learning to appreciate oneanother.Keywords: love, Nigeria, peace, qualitative study, toleranc

The examination of gathering points' capacity regarding mobility and accessibility: Case of Bayrakli district

The concept of accessibility that bases on continuing the flow of people, goods and services uninterruptedly is discussed as "maximum contact by minimum facility". This concept which is related with the distance has been evaluated various criteria such as physical, economic, perceptual, temporal, etc. Several assignations (optimum location, minimum distance, best distribution method, etc.) have revealed the importance of gathering points in terms of proceeding the disaster management properly. The origin point of linking "accessibility" and "transportation network" is the mobility which reveals as accessing people to adequate gathering points and services in the shortest time. These gathering points which are determined due to the specific criteria and also referred to the social infrastructure areas have a vital importance when any disaster or emergencies occur; so the site selection, availability and accessibility of these areas become extremely significant. The aim of this study is to examine the accessibility of gathering points in Bayrakli district located in Izmir city by taking minimum standards and also some recommendations into consideration. The spatial analyses based on current and potential gathering points are carried out via ArcMap software. The current and potential gathering points in Bayrakli district are examined in terms of accessibility their capacity for each neighbourhood due to their spatial distribution. According to the results, each gathering points in neighbourhoods cannot be accessible in the shortest duration by walking and also the current urban pattern affects the capacity parameter regarding the accessibility and mobility significantly. © Authors 2018.

Implementation and Validation of a Real-Time Wireless Non-Invasive Physiological Monitoring in a High-G Environment

The overall purpose of this research is to develop a system capable of real-time personal positioning and physiological monitoring. The system will be composed of a shirt having non-invasive physiological sensors, Global Positioning System (GPS) receiver, wireless data transceiver, and real-time PC-based control station. The specific purpose of this research phase was to determine the performance capabilities of a modified LifeShirt™ alone (without GPS) in a high gravitational force environment with the data being sent wirelessly in real-time. The LifeShirt™ was modified with a real time wireless transmission system

Suppression of stochastic pulsation in laser-plasma interaction by smoothing methods

Smoothing of laser-plasma interaction by ISI, RPP, SSD, etc. was mainly directed to overcome lateral nonuniformity of irradiation. While these problems are in no way less important, we derived numerically the model of the Laue rippling and hydrorelaxation model for explanation of the measured temporal pulsation in the 10- to 40-ps range and how the smoothing schemes suppress these pulsations. The partial standing wave fields of the normally coherent laser-irradiated plasma corona is then suppressed by smoothing and conclusion for tests for this model, e.g., by the "question mark experiment” is given. The result provides a physics solution of the laser interaction problem for direct-drive inertial fusion energ

Modeling interestingness of streaming association rules as a benefit-maximizing classification problem

Cataloged from PDF version of article.In a typical application of association rule learning from market basket data, a set of transactions for a fixed period of time is used as input to rule learning algorithms. For example, the well-known Apriori algorithm can be applied to learn a set of association rules from such a transaction set. However, learning association rules from a set of transactions is not a one time only process. For example, a market manager may perform the association rule learning process once every month over the set of transactions collected through the last month. For this reason, we will consider the problem where transaction sets are input to the system as a stream of packages. The sets of transactions may come in varying sizes and in varying periods. Once a set of transactions arrive, the association rule learning algorithm is executed on the last set of transactions, resulting in new association rules. Therefore, the set of association rules learned will accumulate and increase in number over time, making the mining of interesting ones out of this enlarging set of association rules impractical for human experts. We refer to this sequence of rules as "association rule set stream" or "streaming association rules" and the main motivation behind this research is to develop a technique to overcome the interesting rule selection problem. A successful association rule mining system should select and present only the interesting rules to the domain experts. However, definition of interestingness of association rules on a given domain usually differs from one expert to another and also over time for a given expert. This paper proposes a post-processing method to learn a subjective model for the interestingness concept description of the streaming association rules. The uniqueness of the proposed method is its ability to formulate the interestingness issue of association rules as a benefit-maximizing classification problem and obtain a different interestingness model for each user. In this new classification scheme, the determining features are the selective objective interestingness factors related to the interestingness of the association rules, and the target feature is the interestingness label of those rules. The proposed method works incrementally and employs user interactivity at a certain level. It is evaluated on a real market dataset. The results show that the model can successfully select the interesting ones. (C) 2008 Elsevier B.V. All rights reserved
