Enhanced Performance of Amplify and Forward Cooperative OFDM System in a Hostile Environment
Authors: A. Leftah Hussein 
Published: February 2019

This paper introduces a cooperative orthogonal frequency division multiplexing (CO-OFDM) based on amplify and forward (AF) relay and utilizing a fast low complexity T-transform as a subcarriers modulation scheme. The proposed cooperative system is developed by changing the modulation/demodulation algorithms which significantly enhanced the immunity of the system to deep notches of the multipath channels. Thereafter, the paper presents a mathematical analytic model for the proposed amplify and forward CO-T-OFDM scheme. The use of T-transform in the transceiver of the proposed system enhances the signal diversity. Therefore, the presented AF cooperative system is efficient in enhancing the signal diversity, mitigating the effects of multipath fading channels and achieving more reliable bit-error-rate (BER) performance than the state-of-the-art cooperative system. It also moderates the peaks power of the signal. The BER of the developed AF cooperative system is evaluated by Monte Carlo simulation over frequency-selective multipath channels when AF relay is used, and compared with the BER performance of the standard AF cooperative system. The results show that the developed AF cooperative technology achieves better BER than the classic CO-OFDM under different transmission scenarios.

Published: February 2019

The solar energy development is one of the modern sciences that used the new experiments ideas to reach the benefit. This paper demonstrated the idea of concentrating the solar energy by using two practical models (Model 1 and 2) of parabolic dish with cross sectional area of (1.13 m2) and (2.545m2) respectively for accumulation of solar energy in one focus at Nasiriya city, southern of Iraq (31.036?N,46.21?E). The controlled closed pan was placed at the centre situation of this focus of dish. That used the concentrated solar array heat to raise the focal temperature to many hundreds degrees. So, this small pool used to minimize the heat transfer losses by the convection and radiation way. Also, this small volume increased the concentration ratio to reach the boiling and vaporizing temperature of water which found inside the closed pool. The generated steam leaved the pool to pass throughout the small diameter pipes of condenser that help the steam to decrease its enthalpy to convert the state to liquid. The maximum distillated water for both rigs (model 1 and 2) was 2.5 and 5.25 L/day respectively in 20th of June while the average efficiency was 77.6 % and 76.6 % respectively
MENGGAGAS PENDIDIKAN BERWAWASAN KEWIRAUSAHAAN DI PERGURUAN TINGGI ISLAM

There has been a concern over a high unemployment rate among graduates of Islamic higher education and a low proportion of entrepreneurs in Indonesia. In fact, a high proportion of entrepreneurs is one of indicators of a country’s welfare. This has generated a question: to what extent do Islamic values cultivate entrepreneurial culture among its adherents? How to cultivate entrepreneurial culture in Islamic higher education? This paper will investigate this matter using a case study of Faculty of Islamic Law and Economics at Banten State Institute for Islamic Studies. The paper argues that the curriculum at the faculty of Islamic Law and Economics has not been oriented towards building entrepreneurial culture. The curriculum consists of subjects to enhance the students’ competence and skills to prepare them as bachelors of syari`ah economics for the professions such as manager, lecturer, researcher, syari`ah auditor, etc, instead of preparing them for entrepreneurs who are capable to build his or her own business from the scratch. To propose Islamic entrepreneurship study program at the FSEI of IAIN SMHB, it is important to have a strong political will not only from the internal IAIN but also higher authoritative body such as the Ministry of Religious Affairs to facilitate this from not only the accreditation process but also financial support. A further feasibility study needs to be undertaken to build its infrastructure such as qualified lecturers, appropriate curriculum structure, and recruitment student system. Since this field has a strong link with a ‘real sector’, there has been an urgent need to build cooperations with business sector to enable the students to undertake their apprentice and build their networks to facilitate their ability to develop their own business. Keywords: Islam, entrepreneurship, entrepreneurial education.

Penelitian ini berawal dari keprihatinan yang sedang Melanda negeri ini, tawuran antar pelajar, penjarahan yang dilakukan oleh para geng motor, pencabulan anak dibawah umur yang dilakukan oleh oknum guru hingga pembalakan uang rakyat yang nilainya triliunan rupiah oleh oknum para anggota Dewan Perwakilan Rakyat (DPR) yang terhormat yang saat ini kasus hukumnya sedang ditangani oleh lembaga anti rasuah/Komisi Pemberantasan Korupsi (KPK). Fenomena tersebut menjadi PR besar bagi lembaga pendidikan bangsa Indonesia. Pondok Pesantren Manahijussadat sebagai sebuah lembaga pendidikan Islam modern adalah sebuah lembaga pendidikan yang lebih mengembangkan pendidikan karakter (akhlak) sebagai core kelembagaannya. Perbaikan mental (akhlak mulia) bagi para santri merupakan tujuan didirikannya pondok ini. Pendekatan yang digunakan dalam penelitian ini adalah pendekatan kualitatif (kualitatif research) dengan teknik triangulasi (triangulation technique) dimana data yang dihasilkan oleh peneliti mulai dari wawancara dengan informan inti (mudir/pimpinan pondok) Manahijussadat dan para ustadz dan ustadzah hingga informan tambahan seperti para santri maupun pengamatan langsung di lokasi penelitian. Setelah data terkumpul kemudian diklasifikasikan mana data yang bersifat primer maupun sekunder. Adapun landasan teori yang digunakan dalam penelitian mengacu pada teori sebagaimana yang digagas oleh Zubaedi bahwa pendidikan karakter hendaknya didasarkan pada tatanan nilai yang bersifat absolut, artinya bangunan nilai yang didasarkan pada tatanan keagamaan dan kenegaraan (Agama dan Pancasila) dengan model inside-out dimana perilaku baik bukan hanya dijadikan sebagai sebuah kebiasaan akan tetapi dijadikan sebuah kebutuhan. Ada dua bentuk pola dalam pendidikan karakter yang dilakukan di Pondok Pesantren Modern Manhijussadat, pola tekstual dan pola kontekstual. Pola pertama (tekstual) dilakukan dengan menggunakan pendekatan integrasi keilmuan yang dilakukan oleh para ustaz/ustazah ketika melaksanakan kegiatan belajar mengajar di kelas. Sedangkan pola kedua (kontekstual) dimana pola ini merupakan pola tindak lanjut dari pola pertama. Bangunan pola kedua ini penekanannya pada aspek keteladanan dari semua pihak mulai dari kiai sebagai pimpinan pondok, ustaz/ustazah sampai kepada pengurus pondok atau yang lazim disebut Organisasi Pelajar Pondok Modern Manahijussadat (OPPM) dengan bersama-sama menjunjung tinggi nilai-nilai agama, budaya maupun peraturan Pondok itu sendiri.

A VARIETY OF TEACHING-LEARNING STRATEGIES TO IMPROVE THE CARING BEHAVIOR OF NURSING STUDENTS
Authors: Anna Anastasia , Nuraeni Aan , Praptiwi Atlastieka 
Published: February 2019

Background: Caring is the essence of nursing that is believed vital in improving the health and well-being of patients and in facilitating health promotion. Nursing education has a fundamental role in shaping a positive student’s caring behavior.
Objective: This study identified the caring behavior of the final-year nursing students after completing a critical care nursing course unit by implementing assorted teaching-learning strategies.
Methods: This study was a descriptive research using a comparative design. Samples were recruited from a group of 152 final-year students using a random sampling technique (n=76). Data were collected using a valid and reliable Indonesian caring instrument consisting of 32 items based on Watson’s ten carative factors. Data were analyzed using descriptive statistics by calculating mean scores of students’ caring behavior. A paired t test was performed to evaluate the difference between caring behavior before and after completion of the course unit involving a diverse teaching learning strategy, such as face-to-face lectures in the class, quizzes and practicums, facilitated small group case-based discussions, and expert reviews.
Results: Results showed that more than half of the students had negative caring behavior before (59.22%) and after (54.55%) participating in learning process. There was also a barely statistical insignificance in the change of caring behavior following the course unit that involved various learning strategies (p value = 0.276). Further analyses of the 10 carative factors revealed that there was a significant change in transpersonal teaching-learning, provision for a supportive, protective, and/or corrective mental, physical, sociocultural, and spiritual environment, and spiritual environment and existential-phenomenological spiritual forces (improved, p value <0.05).
Conclusions: Student-centered learning is a good approach to enhance the students’ critical thinking skills. However, in implementing the approach, there is a need to reevaluate appropriate method so as to simultaneously develop students’ critical thinking skills, caring behavior, and empathy.
A Correction for GALEX Spectroscopic UV Flux Distributions from Comparisons with CALSPEC and IUE
Authors: Bohlin Ralph C. , Bianchi Luciana 
Published: February 2019

Abstract
The CALSPEC database of absolute spectral energy distributions (SEDs) from the Hubble Space Telescope is based on pure hydrogen model atmosphere calculations for three unreddened white dwarf stars and represents the current UV flux calibration standard with a precision approaching 1% for well observed stars. Following our previous work to correct International Ultraviolet Explorer (IUE) fluxes, this paper provides an average correction for the Galaxy Evolution Explorer (GALEX) spectral database that places GALEX fluxes on the current CALSPEC scale. Our correction is derived by comparing GALEX spectroscopic flux distributions with CALSPEC and corrected IUE SEDs. This recalibration is relevant for any project based on GALEX archival spectroscopic data, e.g., UV or multi-wavelength analyses, correlating GALEX spectra with other existing or future databases, and planning of new observations. The recalibration will be applied to our planned catalog of corrected GALEX SEDs.
Driving the Beat: Time-resolved Spectra of the White Dwarf Pulsar AR Scorpii

Published: February 2019

Abstract
We obtained high temporal resolution spectroscopy of the unusual binary system AR Scorpii (AR Sco) covering nearly an orbit. The Hα emission shows a complex line structure similar to that seen in some polars during quiescence. Such emission is thought to be due to long-lived prominences originating on the red dwarf. A difference between AR Sco and these other systems is that the white dwarf (WD) in AR Sco is rapidly spinning relative to the orbital period. “Slingshot” prominences stable at 3 to 5 stellar radii require surface magnetic fields between 100 and 500 G. This is comparable to the estimated WD magnetic field strength near the surface of the secondary. Our time-resolved spectra also show emission fluxes, line equivalent widths, and continuum color varying over the orbit and the beat/spin periods of the system. During much of the orbit, the optical spectral variations are consistent with synchrotron emission with the highest energy electrons cooling between pulses. On the timescale of the beat/spin period we detect red- and blueshifted Hα emission flashes that reach velocities of 700 km s−1. Redshifted Balmer-emission flashes are correlated with the bright phases of the continuum beat pulses while blueshifted flashes appear to prefer the time of minimum in the beat light curve. We propose that much of the energy generated in AR Sco comes from fast magnetic reconnection events occurring near the inward face of the secondary and we show that the energy generated by magnetic reconnection can account for the observed excess luminosity from the system.
Identifying Interstellar Objects Trapped in the Solar System through Their Orbital Parameters
Authors: Siraj Amir , Loeb Abraham 
Published: February 2019

Abstract
The first interstellar object, ‘Oumuamua, was discovered in the solar system by Pan-STARRS in 2017, allowing for a calibration of the abundance of interstellar objects of its size and an estimation of the subset of objects trapped by the Jupiter–Sun system. Photographing or visiting these trapped objects would allow us to learn about the conditions in other planetary systems, relieving the need to send interstellar probes. Here, we explore the orbital properties of captured interstellar objects in the solar system using dynamical simulations of the Jupiter–Sun system and initial conditions drawn from the distribution of relative velocities of stars in the Solar neighborhood. We compare the resulting distributions of orbital elements to those of the most similar population of known asteroids, namely Centaurs, to search for a parameter space in which interstellar objects should dominate and therefore be identifiable solely by their orbits. We find that there should be thousands of ‘Oumuamua-size interstellar objects identifiable by Centaur-like orbits at high inclinations, assuming a number density of ‘Oumuamua-size interstellar objects of ∼1015 pc−3. We note eight known objects that may be of interstellar origin. Finally, we estimate that the Large Synoptic Survey Telescope will be able to detect several hundreds of these objects.
Analysis of critical machine reliability in manufacturing cells
Authors: Djassemi Manocher , Seifoddini Hamid 
Published: February 2019

Purpose: In an increasingly competitive business environment, machine reliability problem merits special attention in operations of manufacturing cells. This is mainly due to flow line nature of the cellular layout, interdependency of downstream and upstream of machines related to each other. This study investigates the effect of critical machine reliability improvement on production capacity and throughput time in manufacturing cells. Design/methodology/approach: A discrete-event simulation model was developed to investigate the effectiveness of a reliability plan focusing on the most critical production machines in improving the performance level as an alternative to increasing the reliability of all machines. Four machine criticality policies are examined in the simulation experiments.Findings: The results of this experimental study indicated that an improvement of reliability of a limited number of machines leads to an increase in overall production capacity and speed in cellular manufacturing operations. A reliability plan, that focuses on a set of critical machines, potentially offers a more economical alternative to increasing the reliability of all machines in such facility.Research limitations/implications: The results demonstrate that to achieve higher production capacity and shorter throughput times, managers should consider directing more resources to increase the reliability of critical machines, particularly, those with shorter mean time to failure and higher utilization.Originality/value: The designed simulation model is unique in representing the dynamics of a real world manufacturing cell environment by encoding operational functions such as machine failure, maintenance resource allocation, material flow, job sequencing and scheduling. A new machine availability metric is defined as well.
