ON THE COMPARATIVE ANALYSIS OF THE COOLEY-TUKEY AND BLUESTEIN NUMERICAL FAST FOURIER TRANSFORMS ALGORITHMS FOR DIGITAL SIGNAL PROCESSING
Authors: Amannah Constance Izuchukwu 
Published: March 2018

ABSTRACT This study was designed to compare the computing efficiency of C-TNADSP and the BNADSP to ascertain a more efficient numerical algorithm necessary for the processing of digital signals. The faster numerical algorithm established in this study is abbreviated with RCC-TNADSP (Resultant Compared C-TBNADSP). The methodology adopted in this work was comparative analysis development design. The major technologies used in this work are the C-TNADSP and BNADSP, and the c++. The c++ served as a signal processing language simulator (SPLS). The execution times of the Cooley-Tukey and the Bluestein algorithms were 3.44 seconds and 3.50 seconds respectively. On comparing the speeds of the fast Cooley–Tukey and the fast Bluestein algorithms we observed that the Cooley-Tukey algorithm has 0.06 seconds speed improvement over the Bluestein algorithm. In line with this outcome, we concluded that the Cooley-Tukey algorithm (C-TNADSP) is faster than the Bluestein algorithm (BNADSP). In the same vein the Cooley-Tukey algorithm (C-TNADSP) is therefore the fastest DSP algorithm. This is however faster than the spectrum of FFT algorithms of O(nlogn) computing speed. The algorithms were tested on input block width 1000 units, and above, and can be implemented on input size of 100 000, and 1000 000 000 without the challenge of storage overflow. The input samples tested in this work was the discretized pulse wave form with undulating shape out of which the binary equivalents were extracted. Other forms of signals may also be tested in this fast algorithm provided they are interpreted in the digital wave type. KEYWORDS: Algorithm, FFT, Cooley-Tukey, Bluestein, Comparison, Analysis, FFT

El plano de la ‘lectura’ en la ‘Eneida ovidiana’ (Met., XIII, 623- XIV, 608): Ovidio, Virgilio y el Aeneas Romanus
Authors: Martínez Astorino Pablo 
Published: March 2018

Al margen de la “mitologización”, cuyo fin es incluir las historias de esta larga secuencia en la trama precedente constituyendo una historia universal “mitologizada”, hay en la llamada “Eneida ovidiana” marcas textuales que sirven para mantener vigente el valor de la figura y la historia de Eneas en conformidad con la significación romana del héroe y, en especial, con la apoteosis, que da fin a la secuencia. Tales marcas constituyen lo que hemos dado en llamar el plano de la “lectura”. En este trabajo indagamos, a propósito de la “Eneida ovidiana”, las alusiones al Aeneas Romanus, construido en particular por la obra de Virgilio y al que Ovidio sigue en cuanto al significado general, más allá de ocasionales referencias a tradiciones previas no incluidas por Virgilio. Entendemos por Aeneas Romanus el que, dada la índole canónica de su Eneida, Virgilio termina de convertir en patrimonio de la cultura romana, sancionando a la vez su carácter de mito originario de una familia. Entre esas alusiones es central la designación Cythereius heros en Ringkomposition, que remeda Aen., I, 257-258 y asegura el valor virgiliano de la secuencia en el plano de la “lectura”.

Telah dilakukan penelitian analisis waktu pemupukan pada tanaman sawi hijau (Brassica rapa var. parachinensis)dengan teknik perunut radioaktif. Untuk menuju sistem pertanian berkelanjutan perlu adanya perbaikan pertanian(intensifikasi) selama beberapa tahun yang lalu masih signifikan, karena ketersediaan sumber daya alam danteknologi pertanian cukup memadai dan berimbang dengan ketersediaan lahan dan peningkatan jumlah penduduk.Keadaan ini sulit untuk dipertahankan dimasa yang akan datang, kecuali ada pendekatan baru yang menawarkan ide dan teknik untuk meningkatkan produktifitas pertanian. Efesiensi pemupukan tanaman dengan teknik perunut (tracer) radioisotop adalah salah satu potensi menujusistem pertanian berkelanjutan. Teknik perunut dapat digunakan antara lain untuk mempelajari hubungan antaratanah dan tanaman, menentukan kondisi optimal dalam penggunaan pupuk (waktu pemupukan, pola perakaranaktif tanaman, jenis dan takaran pupuk), mempelajari proses dekomposisi dan mineralisasi bahan organik, sertamempelajari proses fotosintesis tanaman,baik dengan metoda langsung maupun tidak langsung.Waktu pemupukanyang lebih tepat dapat ditentukan dengan teknik perunut tersebut, sehingga optimalisasi pemupukan dapat dicapai,tanpa pemborosan yang tidak berguna.Dari penelitian dengan menggunakan radioisotop P, ternyata waktupemupukan pada tanaman sawi hijau (Brassica rapa var. parachinensis) yang paling signifikan adalah padapukul 9.00 pagi. Waktu siang hari mulai pukul 11.00 sampai pukul 15.00 adalah waktu pemupukan yang sangatburuk. Sedangkan waktu sore hari yaitu pukul 15.00 sampai 17.00 menunjukkan waktu pemupukan yang semakinbaik namun tidak signifikan.32

The development of free-range chicken farm is constrained by expensive food prices. On the other hand,feses of cattle had potential use as a source of feed. This study was conducted to determine the response ofcow feses and probiotics administration in the diet of laying range chicken. The study was conducted over 6months using 240 free-range chickens aged 8 months. Research was arranged in a completely randomized designwith 8 treatments and 5 replications. The treatment given were ration in accordance with the farmers formulacomprising: concentrate: 25%, corn 40% and rice bran 35% (P0) and ration as P0, with the substitution of ricebran with fermented cow feses each treatment with level 10 % (P1), 15% (P2) and 20% (P3) and ration as atP0, P1, P2 and P3 that received additional probiotic (Bio L) 1 cc / L of drinking water (P4, P5, P6 and P7). Theparameters were observed are: egg production (hen day), egg weight, feed intake, FCR (Feed Conversion Ratio)mortality and physical composition of eggs. The results showed that the diet which containing fermented cowfeses 20% did not decreased egg production and feed efficiency. The combination of fermented cow feses at thelevel of 20% with a probiotic (Bio L) 1 cc / L of drinking water showed that egg production increased althoughit is not significant and reduce the number of FCR (Feed Conversion Ratio). In conclusion the use of fermentedcow feses up to the level of 20% in the diet both with and without the administration of probiotics, has no effecton physical composition of eggs.

Published: March 2018

This studyaimed to analyze mathematicsteachersconceptions(beliefs) about mathematical modeling in Palembang. In this study presents a case study of 60 mathematics teachers, investigating their conceptions about mathematical modeling and their experiences of working with modeling activities in Palembang. In particular, basic concepts of mathematical models, mathematical modeling, and mathematical modeling in education were analyzed. Quantitative data were collected through a questionnaire of sample of practicing teachers of mathematics in Palembang. The data showed that mathematics teachers in Palembang hold several misconceptions about models and modeling, particularly regarding aspects of the mathematical modeling process. Specifically, the majority of teachers does not understand that the mathematical modeling process always requires making choices and assumptions, and that mathematical modeling situations must come from real-world scenarios. The results indicate that the teachers in this study seem not to give priority to integrating mathematical modeling into their everyday mathematics teaching.

Authors: Thi Tinh Duong 
Published: March 2018

More than 40 years of establishing diplomatic relations and developing trade between Vietnam and Germany, it can be seen that Germany is the biggest trading partner of Vietnam in Europe and the largest importer of Vietnam’s exports to the EU. Although the trade between the two countries has not reached expectations, and the results are still inferior to the potential, the prospects for trade between the two countries are great and need to be further developed due to the favorable context and the advantages of the free trade agreement between Vietnam and the EU. This paper analyzes the current state of trade relations between Vietnam and Germany, assesses the advantages and disadvantages, and suggests policy implications for developing trade relations between the two countries in the future.

Characterization of interfaces in tri-layered brass/steel/brass composites fabricated by casting and hot dipping
Authors: Rahimi Amir Mahdi , Amadeh Ahmad Ali 
Published: March 2018

AbstractTri-layered brass steel/brass laminated composites were fabricated through hot dipping as well as casting. The chosen temperatures for hot dipping were 1 150 °C and 1 350 °C and for casting was 1 150 °C in addition to performing a heat treatment cycle at 900 °C for 90 min. The characterization results revealed that in the as-cast and the heat-treated samples, the formation of Fe-Zn intermetallic compounds occurred. In addition, with increasing the hot dipping temperature, stronger interfaces were achieved due to easier diffusion at higher temperatures. Moreover, casting without heat treatment was enough to obtain good bonding since the amount of Fe3Zn10 intermetallic compound increased and grain growth occurred.
Détection d’événements indésirables par la méthode des trigger tools à partir des dossiers de régulation au sein d’un CRRA 15
Authors: Bechu M. , Payet I. , Bounes V. 
Published: March 2018

Objectif : La méthode dite des trigger tools permet une analyse objective, rapide et fiable des risques portant sur l’examen de dossiers de patients ciblés afin de mettre en évidence des d’événements indésirables (EI) évitables ou porteurs de risques (EPR). L’intérêt de cette méthode n’a jamais été étudié dans le cadre d’un centre de réception et de régulation des appels 15 (CRRA 15). L’objectif était d’évaluer la pertinence de triggers choisis au sein d’un CRRA 15 afin de mettre en place un système de détection d’EI par la méthode des trigger tools.
Matériel et méthodes : Au sein du SAMU 31, au CHU de Toulouse, les dossiers de régulation (DR) étaient extraits en cas de déclenchement de triggers prédéfinis : délais de départ SMUR, délais d’arrivée, temps de prise en charge sur place, délais de décision d’envoi d’une équipe SMUR après le premier appel, patients décédés et réorientations des patients dans les 48 heures. Le critère de jugement principal était le pourcentage d’EI évitables et d’EPR, parmi les patients dont le dossier a déclenché un trigger donné, c’est-à-dire la prévalence du trigger. Les critères de jugement secondaires étaient la gravité de chaque EI évitable selon l’AHRQ severity scale et les facteurs favorisant leur survenue.
Résultats : Du 9 juillet 2011 au 13 avril 2012, 174 536 DR ont été traités, 4 404 (2,5 %) ont déclenché un trigger (soit 2 882 patients). On retrouvait 203 DR avec un EI, qui concernaient 153 patients ; 73 présentaient un EI évitable, 16 un EPR, 30 un EI non évitable. La prévalence de chaque trigger était de 17,6 % (IC 95 % : 4,8–20,4 %) pour celui « délai de départ », 6,7 % (IC 95 % : 3,7–9,7 %) pour le trigger « réorientation précoce », 6,4 % (IC 95 % : 4,6– 8,2 %) pour celui « délai de décision SMUR », 3,4 % (IC 95 % : 0,1–7,2 %) pour le trigger « temps sur place », 2,9 % (IC 95 % : 0,1–8,5 %) pour celui « délai d’arrivée » et 3 % (IC 95 % : 1,5–4,5 %) pour le trigger « décès ».
Conclusion : Les triggers qui semblaient les plus pertinents étaient donc « délai de décision SMUR », « réorientation précoce » et « décès ». La méthode des trigger tools permet une analyse rapide et efficace des DR, essentielle pour réduire le risque et améliorer la qualité de prise en charge des patients.
Review of State Boards of Nursing Rules and Regulations for Nurse Preceptors
Authors: L'Ecuyer Kristine M. , Lancken Shelley von der , Malloy Diane , Meyer Geralyn , Hyde Matthew J. 
Published: March 2018

Background:
The clinical education of undergraduate nursing students relies heavily on the use of staff nurses who assume the preceptor role. The best and most efficient utilization of preceptors is unknown.

Method:
This study reviewed Board of Nursing rules and regulations for all 50 states, the District of Columbia, and the U.S. territories for their published requirements regarding preceptors. Specifically, this review focused on preceptor–student and faculty–student ratios, role responsibilities, and requirements of preceptors and faculty in undergraduate precepted clinical experiences.

Results:
Although some commonalities were noted, such as eligibility (RN licensure), degree requirements (baccalaureate), and years of experience (1 to 3), 11 states had no documented regulations. The existing documents appear to lack depth, specificity, and consistency.

Conclusion:

Because preceptors are utilized to such a great extent, the eligibility, selection, preparation, and expectations of preceptors and faculty who work with them should be more explicit. [

Using Student-Produced Video to Validate Head-to-Toe Assessment Performance
Authors: Purpora Christina , Prion Susan 
Published: March 2018

Background:
This study explored third-semester baccalaureate nursing students' perceptions of the value of using student-produced video as an approach for learning head-to-toe assessment, an essential clinical nursing skill taught in the classroom.

Method:
A cognitive apprenticeship model guided the study. The researchers developed a 34-item survey. A convenience sample of 72 students enrolled in an applied assessment and nursing fundamentals course at a university in the western United States provided the data.

Results:
Most students reported a videotaping process that worked, supportive faculty, valuable faculty review of their work, confidence, a sense of performance independence, the ability to identify normal assessment findings, and few barriers to learning.

Conclusion:

The results suggested that a student-produced video approach to learning head-to-toe assessment was effective. Further, the study demonstrated how to leverage available instructional technology to provide meaningful, personalized instruction and feedback to students about an essential nursing skill. [

EFL teachers’ perceptions about an online CALL training. A case from Turkey
Authors: Cengiz Behice Ceyda , Seferoğlu Gölge , Günseli Kaçar Işıl 
Published: March 2018

<p>This paper examined a group of Turkish EFL in-service teachers’ perceptions about a four-week online CALL training they received on a voluntary basis. The data were collected via a background questionnaire, interviews and reflection reports written by the participating teachers. Findings demonstrated that online CALL training was beneficial for the teachers since they gained familiarity with cutting-edge CALL technologies and developed ideas about how to use them in their classes. CALL learning in cyberspace, however, was found to be too challenging for some teachers devoid of the computer skills needed to manage the online experience. Most of the teachers also expected the CALL training to be situated in their classroom contexts providing them with ample opportunities to learn and apply CALL in their local teaching contexts. Taking the various needs of the teachers into consideration, the researcher came up with suggestions for future initiatives for in-service CALL teacher education. </p>
