Published: February 2021

This research work analyzed the impacts of Federal government expenditure in education on Nigeria economic growth. The study used secondary data from 1980 to 2018 and the information gathered was presented and analyzed through E-view. The study makes use of analytical statistics for the analysis of the data collected. The Ordinary Least Square (OLS), and ADF Test were employed in order for certainty, reliability of the results and to guard against obtaining spurious results. Adaptive model was employed in order to capture the short and long run effect of Federal Government expenditure in education (GEDU) on economic growth and the hypothesis say that, there is no long run impact of Federal government expenditure in education on Nigeria economic growth. However, the findings show that there is positive impact between RGDP and GEDU, and Comparing GEDU of the short run and the long run, it could be seen that the impact of Federal government expenditure in education is greater in the long run with 7.5% than in the short run. However, the challenges observed are instability, and inadequate government expenditure in education. Therefore the study recommends that quality education make labour more productive and the multiplier effect will cause an increase in aggregate output of the economy.

Optical Isolation using Compact Time-modulated Cavity Array
Authors: Mock Adam
Published: February 2021

It is shown using coupled mode theory and verified using finite-difference time-domain simulations how a time-modulated three-cavity array can be designed to allow transmission from port 1 to port 2 but to prevent transmission from port 2 to port 1 thereby implementing optical isolation. The reciprocity of the system is broken by phase-shifting the modulation signal applied to each cavity by 120 degrees which gives the system a synthetic linear momentum.

Published: February 2021

The technology of additive manufacturing results in 3D printing of conductive traces in radio frequency circuits. This creates a plethora of possibilities in realizing flexible and wearable electronics. While the prototypes of microstrip transmission lines and antennas have been recently reported, there is now a need of Electromagnetic Compatibility based study of such 3D printed conductive traces. This paper presents a comparative study on the near end and far end unintentional crosstalk components between a pair of microstrip transmission lines made of Copper in the presence of a 3D printed conductive trace made of a commercially available conductive filament, Electrifi. Any physical contact with the 3D printed trace has been purposefully averted to discard the high contact resistance between the trace and such contacts.

Rectangular Slot Array Antenna
Authors: Trinidad Garcia Elvis , Ortega Ruben , Tabet Saad
Published: February 2021

Slot antenna elements are quite popular for use in flat-panel arrays, due to their compactness and relatively large bandwidth. According to Babinet’s Principle, slots and dipoles are duals in performance. Therefore, a vertically placed slot is horizontally polarized and a horizontally placed slot is vertically polarized. A rectangular slot array lends itself to a broad range of applications, e.g., tactical and weather radar. Such arrays can be gimbaled to point their beam in any azimuth and elevation angle of interest. In this effort, a slot antenna element is designed in WIPL-D Pro to operate over the 7.5 - 8.5 GHz frequency range. The element is designed to resonate at 8 GHz. The slot element is used to generate a 6x12 slot array normal to the xy-plane. Separate Taylor tapers (nbar = 5) are applied to the 6-row and 12-column elements to provide 25 dB and 30 dB sidelobe level (SLL) suppression, respectively. The input impedance and pattern performance for a single slot, as well as the slot array’s radiation performance show excellent broadband performance.

This paper employed a multi-objective Genetic Algorithm (GA) process to optimize the structure parameters of Linear Proportional Solenoid (LPS). And designed objectives include magnitude of static push force, stability of push force with displacement in working range and push force to mass ratio. A two-dimensional finite element analysis model is presented to reduce the large calculation time generated by GA process. The optimization process result of LPS shape parameters is obtained and the optimal LPS is
manufactured. Through using a high-precision measuring device in the static push force test, a comparison result between conventional shape and optimal shape shows that the proposed optimization strategy is feasible.
Compressing H2 Matrices for Translationally Invariant Kernels
Authors: Adams R. , Young J. , Gedney S.
Published: February 2021

H2 matrices provide compressed representations of the matrices obtained when discretizing surface and volume integral equations. The memory costs associated with storing H2 matrices for static and low-frequency applications are O(N). However, when the H2 representation is constructed using sparse samples of the underlying matrix, the translation matrices in the H2 representation do not preserve any translational invariance
present in the underlying kernel. In some cases, this can result in an H2 representation with relatively large memory requirements. This paper outlines a method to compress an existing H2 matrix by constructing a translationally invariant H2 matrix from it. Numerical examples demonstrate that the resulting representation can provide significant memory savings.

Authors: Weiss Alec , Elsherbeni Atef
Published: February 2021

MATLAB and Python are two commonly used scripting languages for prototyping electromagnetic problems today. Each of these languages provides access to
computationally efficient functions allowing a user to easily run many math heavy problems with minimal programming. In this paper we will discuss the usage of MATLAB and a variety of libraries in Python capable of running these efficient computations. Tests will be run in both languages to compare both CPU and GPU computations. The runtimes of a variety of problems using each of these platforms will also be compared for a variety of mathematical operations typically used in electromagnetic problems. Finally, a simple angle of arrival calculation using conventional beamforming will be performed to show these speeds on a realistic problem.

Published: February 2021

We evaluate the feasibility of a quantum monopulse radar, focusing on quantum illumination (QI) radars and quantum two-mode squeezing (QTMS) radars. Based on their similarity with noise radar, for which monopulse operation is known to be possible, we find that QTMS radars can be adapted into monopulse radars, but QI radars cannot. We conclude that quantum monopulse radars are feasible.

Authors: Perez-Greco Gianfranco , Barreto Juan , Kaddour Abdul-Sattar , Georgakopoulos Stavros
Published: February 2021

In this paper, the effects of different parts of the human body on a wearable Wireless Power Transfer (WPT) system are examined. A Strongly Coupled Magnetic Resonators
(SCMR) WPT system operating in the ISM band 40.68 MHz is used in this study. The results show that when the WPT system is placed directly on the human body its Power Transfer Efficiency (PTE) is reduced by 13% on average in both simulations and measurements. These losses are attributed to the material properties of the human body. Also, different parts of the human body cause different drops in PTE due to their different shapes and geometries.

La Organización Internacional para las Migraciones (OIM) define a un migrante como cualquier persona que se desplaza, o se ha desplazado, a través de una frontera internacional o dentro de un país, fuera de su lugar habitual de residencia independientemente de: su situación jurídica, el carácter voluntario o involuntario del desplazamiento, las causas del desplazamiento; o la duración de su estancia. Se estima que al menos 272 millones de personas viven fuera de su país de origen, lo que representa al 3,5% de la población mundial. Venezuela es uno de los países con mayor flujo de migrantes de la actualidad, cifras de la Oficina de las Naciones Unidas para los Refugiados (ACNUR), estiman que más de 4 millones de venezolanos han abandonado el país debido a la crisis económica, política y social que atraviesa, convirtiéndolo en uno de los grupos de poblaciones desplazadas más grandes del mundo. Lo anterior, ha traído consecuencias significativas a la seguridad ciudadana de los países receptores, para el caso de Colombia, la Fiscalía General de la Nación reportó que, entre enero de 2017 y febrero de 2018 se registraron 1.869 capturas de ciudadanos venezolanos en flagrancia. Pese a esto, son escasos los estudios que analizan la relación entre crimen y migración. Es por esto, que se lleva a cabo una investigación mixta con un enfoque reflexivo no experimental, cuyo objetivo es contrastar el impacto de la migración masiva de ciudadanos venezolanos y su repercusión en la seguridad de los residentes del municipio de Cajicá.

Penelitian ini bertujuan untuk membuat siswa berani, menumbuhkan kepercayaan diri serta melatih siswa dalam berbicara menggunakan bahasa Inggris dan sehingga mampu mengekspresikan kalimat-kalimatnya secara aktif dan kreatif sehingga untuk meningkatkan nilai Speaking (berbicara) mereka. Objek penelitian ini adalah siswa kelas X SMA Negeri 1 Cibinong Kabupaten Bogor tahun pelajaran 2019/2020. Penulis adalah guru bahasa Inggris di SMAN 1 Cibinong kelas X IPA dan IPS. Penelitian ini dibuat atas dasar permasalahan yang dihadapi penulis yaitu ketika  dalam aktivitas belajar mengajar bahasa Inggris, siswa diminta berbicara dalam bahasa Inggris atau mengekspresikan ungkapan-ungkapan yang sudah dipelajari, mereka berbicara dengan rasa takut, tidak percaya diri, gugup dan terbata-bata bahkan ada saja siswa yang tidak mengeluarkan kata sepatahpun. Penulis menemukan sebagian besar siswa tidak mampu berekspresi dengan benar dan tidak percaya diri meskipun hanya diminta memperkenalkan dirinya sendiri. Hal ini mungkin disebabkan oleh faktor internal dan eksternal dari mereka. Untuk mengatasi masalah tersebut penulis mencoba menggunakan aplikasi robot online versi android (ESL ROBOT PRO) yang difasilitasi oleh website WWW.ESLFAST.COM ( robot online yang digunakan untuk belajar bahasa Inggris bagi pembelajar dari negara yang bahasa Inggris merupakan bahasa ke dua atau bahasa asing ) untuk berlatih berkomunikasi dalam bahasa Inggris kapan saja dan dimana saja yang diakses melalui mobilephone (telepon genggam). Aplikasi inipun sangat mudah diunduh dan tidak ada batasan waktu untuk penggunanya. Metode penelitian yang dipakai adalah metode deskriptif kualitatif dengan menggunakan lembar observasi yang berisi rubrik penilaian Speaking dan lembar observasi kontrol aktivitas. Siswa diminta mengirimkan video rekaman ketika mereka sedang berbicara dengan si robot dan hasil pembicaraan (chatting) yang discreenshot. Hasil observasi menunjukkan adanya peningkatan kemampuan berbicara siswa dan terlihat sebagian besar siswa termotivasi, percaya diri yang membuat mereka menjadi kreatif, senang, dan bisa mengaplikasikan apa yang sudah mereka pelajari bahkan orangtua dan anggota keluarga yang lain ikut memanfaatkan aplikasi robot online ini.

The aim of this study is to examine the opinions of boarding district secondary school students and teachers on school-family communication. The study was carried out according to the phenomenology of the qualitative research method. The participants consisted of six students and three teachers. Students were from the different family structure, gender and academic achievement level. Students also studied in different classes of the boarding district secondary school in a district of central anatolia region in the spring term of 2018-2019. On the other hand, teachers were from the different disciplines, age levels and family communication. Semi-structured interview was employed as data collection tool. The data obtained from the interviews were analyzed with descriptive and content analysis. In the study, it was understood that students and teachers perceived school-family communication as supporting students' education and teaching activities. The most cited sources of communication by students and teachers; telephone conversation, parent meeting, family visit and telephone message. In the study, it was determined that the students are willing to communicate and they communicate about academic achievement. Teachers, on the other hand, were found to communicate with students' academic achievement as well as student problems and financial issues. In addition, it was concluded that the teachers wanted to communicate about academic success, social activities and home life. The common opinions of both participating groups regarding the problems in family-school communication; distance, suitable meeting time, family apathy and economic conditions. Participants suggested carrying out family visits, organizing social events, increasing the parents' interest and using different communication sources as a solution proposal. Based on the findings and limitations of the research, suggestions were made to increase the school-family communication.

Covid-19 pandemic cases are currently increasing and expanding throughout the world, especially in Indonesia in the province of North Sumatra. Data on the number of cases spread in the province of North Sumatra which is summarized and published, sometimes there are still disputes over the number and lack of organization in the number of records and their distribution, so there are often errors in the data collected by the health department and which will be published to the public. The case study in this research is the design of an information system that regulates the process of recording, moving, accumulating, and mapping GIS data maps to the publication of Positive case data, Patient Under Surveillance, Polymerase Chain Reaction, and Rapid Test results directly through a web-based covid-19 data reporting application. Sourced from each user of every health facility in each district and city from each sub-district in the province of North Sumatra to support the accuracy of data in decision-making built at the North Sumatra Province Information and Communication Office. The method used in developing the application uses the waterfall method, starting from the needs analysis stage, design, implementation to testing until maintenance. The results of the implementation and testing were carried out using the Blackbox and Whitebox methods. Presentation of GIS web data using google maps has not used a threshold value based on a calculated algorithm, but still uses the determination of crisp values so that the results cannot be said to be relevant as a determinant.
Determinants of Adoption of Ecosystem-Friendly Farming Practices for Sustainable Agricultural Development in Ghana

Agriculture plays a key role in economic growth, enhancing food security, poverty reduction and rural development. Future food security and economic independence of developing countries would depend on resilient ecosystems for a sustainable agricultural development. Intensive agriculture with high inputs has resulted in rapid crop production in Ghana, accompanied by negative environmental effects. The adoption of ecosystem-friendly farming technologies, which do not destroy nature, would ensure these negative effects are addressed. However, the rate of adoption of these practices has remained low in Ghana. This paper explores the determinants of adoption of ecosystem-friendly farming practices (EFFPs) in Northern region of Ghana with a sample of 300 farmers. The results revealed that sex, age, educational level, household size, production system, credit access, previous income, market access, and expected benefits from the adoption influenced EFFPs adoption. The adoption of EFFPs should be made a precondition for farmers to gain access to desirable opportunities such as input subsidies, good pricing among others.

Crop water productivity models are important tools in evaluating the effect of different irrigation regime on crop yield. AquaCrop model is a crop water productivity model adopted by the Land and Water Division of FAO in the year 2009. It simulates yield response to water for herbaceous crops, and it is particularly suitable in addressing conditions where water is a key limiting factor in crop production such as in northern Ghana. The objective of this study was to calibrate the AquaCrop model for different irrigation regimes for onion (Allium cepa), to determine its effect on crop growth and yield parameters of the crop at the Bontanga irrigation scheme. To achieve these, the Randomised Complete Block Design (RCBD) was used on Red Creole onion variety. RCBD was made up of four irrigation treatment regimes, 117%, 100%, 80% and 60% crop water requirements (CWR) of onion, with five replicates. Results indicated that there was no significant variation in yield, dry bulb biomass and total biomass, but there was difference for dry leaf biomass of onion at 0.05 significance level. The AquaCrop model simulated satisfactorily the crop yield, biomass and evapotranspiration water productivity of onion. There was a strong correlation and a significant linear relation between the simulated and measured crop yield, biomass and evapotranspiration water productivity. Validation of AquaCrop model using Nash-Sutcliffe efficiency (E), Root mean square errors (RMSE) and index of agreement (d) showed that, AquaCrop model can be used to simulate CWR of bulb crops, such as onion.

Published: February 2021

The study assessed performance and state of water retention infrastructure of eight (8) irrigation schemes in three (3) northern regions of Ghana. Data was collected using field observation and key informants’ interviews. The results indicated that the Tono and Bontanga earthen irrigation dams’ embankments had no structural defects whereas the embankments of Libga, Golinga, Karni, Vea, Doba and Sankana had some structural defects. Except Libga, all the spillways had no structural deficiencies and signs of risk of failure. All the reservoirs contained some amounts of sediments and weeds. The night storage reservoirs at Tono and Vea were weedy and silted up. The developed irrigable areas of Vea, Tono, Doba, Sankana and Karni schemes had average irrigation rates ranging from 12 - 76 % for the years 2010 - 2017. The water retention infrastructure of the irrigation schemes are recommended for maintenance and periodic repairs to ensure sustainable water retention and availability for crop irrigation.
