Literatur Riview Transliterasi Hurub Arab ke Latin
Authors: Nurwakit Ahmat
Published: July 2021

Computer vision adalah bidang interdisiplin yang mempelajari tentang bagaimana komputer dapat melakukan pemahaman terhadap citra digital dan video. Dalam persepektif engineering computer vision ditujukan untuk melakukan automasi terhadap sistem visual manusia. Tahap dalam computer vision meliputi pengambilan (acquiring), pemrosesan (processing), analisis (analyzing) dan pemahaman (understanding) terhadap citra digital. Computer vision berfokus pada sistem cerdas yang dapat melakukan ekstraksi data dari citra digital ke dalam bentuk numerik Sub domain dari computer vision meliputi  scene reconstruction, event detection, video tracking, object recognition, 3D pose estimation, learning, indexing, motion estimation, dan image restoration. Handwriting character recognition (pengenalan tulisan tangan) adalah salah satu cabang dari object recognition, yaitu kemampuan komputer untuk menerima dan menafsirkan input tulisan tangan yang dapat dimengerti dari sumber seperti dokumen kertas, foto, layar sentuh dan perangkat lainnya. Gambar dari teks tertulis dapat digunakan secara luring dari selembar kertas oleh pemindai optik (rekognisi karakter optik). Selain itu, gerakan ujung pena dapat dimengerti secara daring, misalnya dengan menggunakan permukaan layar komputer berbasis pena. Salah satu aksara yang dijadikan objek dalam pengenalan tulisan tangan adalah huruf huruf arab pegon (yang selanjutnya disebut pegon). Huruf pegon biasa digunakan dalam terjemah kitab kuning dalam bahasa daerah (umunya) Jawa, Sunda, atau Melayu. Kenyataannya terjemah kitab-kitab kuning klasik di indonesian lebih banyak menggunakan 3 bahasa tersebut, sehingga orang-orang  yang tidak menguasai salah satu dari bahasa tersebut akan kesuliatan untuk mendapatkan terjemah.Berbeda dengan huruf arab baku, huruf  pegon memiliki beberapa karakter yang merupakan rekayasa agar dapat dibaca menyesuaikan lidah bahasa daerah bersangkutan. Masalah yang muncul adalah huruf pegon tidak dapat dibaca oleh seseorang yang tidak memiliki kosa kata dalam bahasa bersangkutan sehingga membutuhkan proses penerjemahan. Proses penerjemahan sendiri hanya mungkin dilakukan jika kalimat tertulis dalam huruf latin. Pengenalan tulisan tangan saat ini sudah banyak dilakukan menggunakan banyak metode, terutama yang paling banyak dari varian Jaringan Syaraf Tiruan (neural network). Walaupun tingkat akurasi dari neural network tinggi, tetapi computatiion cost metode-metode ini sangat besar.  Eigenspace adalah subspace dari aljabar linier yang terdiri dari sekumpulan eigen vector. Tiap eigen vector terbentuk dari banyak eigen value. Salah satu pemanfaatannya adalah eigenface yang digunakan dalam pengenalan wajah. Caranya adalah dengan mengubah citra digital ke dalam eigen value yang kemudian disusun menjadi eigen vector. Data uji kemudian akan dihitung jaraknya terhadap semua vector yang ada kemudian diambil yang nilainya paling dekat. Metode ini cukup low cost.

El nombre. Derecho Humano relacionado al interés Superior de los infantes
Authors: Ortega-Laurel Carlos
Published: July 2021

El nombre tiene una doble naturaleza jurídica, está claramente reconocido como un atributo de la personalidad (perspectiva civilista) y como un derecho humano. Sin embargo, aun cuando se trata de un derecho de las personas, la elección de éste siempre es una potestad de terceras personas (por regla general los progenitores). Lamentablemente este derecho hacía los padres o tutores goza de una libertad excesiva, que en muchas ocasiones ha sido dañina hacía la dignidad de los infantes. Es por ello por lo que se sugiere algunos marcos que delimiten la libertad de elección del nombre en aras del interés superior del menor. Se hace alusión a la más reciente reforma al Código Civil de la Ciudad de México.

Kedudukan Dan Fungsi Wakil Presiden Republik Indonesia Dalam Sistem Ketatanegaraan Indonesia
Authors: Suparto Suparto
Published: July 2021

The position of the Vice President and the President is not equal, even though the President and Vice President are a single inseparable institution. The position of the President and Vice President which is not equal shows that the presidential institution is the organizer of a single government system. The position of the Vice President cannot be separated from the President as a unit of positions which are directly elected by the people through general elections. Then, the duties and powers of the Vice President in the 1945 Constitution do not provide regulation, because the provisions of Article 4 paragraph (2) of the 1945 Constitution only mention their duties as assistant to the President, even though the President and Vice President are a single unit of office elected by the people through general elections. The authority of the Vice President is the authority mandated by the President to assist the President in implementing laws so that the responsibility remains with the President. The authority of the Vice President as a substitute for the President is all the powers that are in the position of President. In the future, it is necessary to make a law as an elaboration of the provisions of Article 4 paragraph (2) of the 1945 Constitution

Swelling behaviors of crosslinked acrylamide (AAm)/carboxymethyl cellulose sodium salt (CMC) blend hydrogels synthesized using gammaradiation from Co-60 source in aqueous solutions of urea were investigated. The parameters like effect of radiation dose and concentration of CMC in AAm/CMC blend were studied on swelling properties. Swelling experiments were performed in various concentrations of urea solution and distilled water at room temperature. The swelling properties of hydrogels increased with increased concentration of CMC but it decreased with increased radiation dose. Hydrogels showed enormous swelling in aqueous solution of urea. The swelling properties of AAm/CMC hydrogel were lower in distilled water than that of in urea solution. The water absorption of AAm/CMC blend hydrogels increased from ~4,800 to ~9,000% for the concentration range of CMC from 0 to 7% for 48 hours standing in distilled water at 25 kGy radiation dose. It was also found that water absorption by AAm hydrogel with 7% CMC decreased from ~13,800 to ~8,500% for the radiation range from 15 to 35 kGy for 48 hours standing time in water. The equilibrium water content (EWC) of AAm/CMC blend hydrogel depended on radiation dose. EWC decreased from ~0.9935 to ~0.9896 with the variation of radiation dose from 15 to 35 kGy in 0.01M urea solution at 48 hours.

Authors: Hossain ASM Monjur Al , Dutta Konika Rani , Hossain Md Lokman
Published: July 2021

Ibuprofen Solid Dispersion (SD) was prepared by simple Physical Mixing (PM) and Kneading Method (KM). In these two cases, four polymers named poloxamer 407, sodium carboxy methyl cellulose, croscarmellose sodium and pregelatinized starch were used to enhance the dissolution profile of Ibuprofen. In both methods, the ratio of drug and carrier were 1:1, 1:2, 1:3 of which the ratio of 1:3 in KM gave comparatively better result than PM method. In vitro dissolution study was performed in distilled water in 50 rpm and at 37 ± 0.5°C. In case of pure Ibuprofen, dissolution rate was only 26% after 60 minutes (mins) of dissolution. While in KM, Ibuprofen pregelatinized starch formulation at 1:3 ratio showed better dissolution rate. After 60 mins, dissolution rate of Ibuprofen was 72%. The SD formulations of Ibuprofen-pregelatinized starch and Ibuprofen-Na-CMC of physical mixing and kneading techniques (1:3 ratio) were characterized by Fourier Transform Infrared Spectroscopy (FTIR).

This study investigates the relationship between previous birth interval and infant mortality using the data extracted from the Bangladesh Demographic and Health Survey (BDHS), 2011. For the purpose of regression analysis, the Cox proportional hazard model has been used. Results demonstrate significant effects of previous birth interval on neonatal mortality, but not on post neonatal mortality. If the previous birth interval is less than two years or greater than three years, the index child experiences high risk of neonatal mortality.

Comparative Study for Photodegradation of Remazol Red R by Different TiO2 Samples
Authors: Rashed Nurnabi , Mazumder AZM Mainul Islam , Hossain Md Mufazzal
Published: July 2021

Potassium dichromate modified TiO2 photocatalyst (MD-TiO2) was prepared and its photocatalytic activity was compared with that of ordinary commercial TiO2 (C-TiO2) and special Degussa P25 TiO2 (D-TiO2). An organic dye, remozol red R(RRR) was used as a substrate for photodegradation from aqueous solution into environmentally safe products such as water, carbon dioxide and mineral ions. The photodegradation of RRR was carried out by varying the concentration of different types of TiO2 suspension, initial concentrations of dyes between 0.5× 10-4 M and 2.5 ×10-4 M, pH between 2.0 and 6.0 and light sources which are UV, artificial visible and sunlight. With increasing the catalyst concentration, percent degradation was found to increase up to a concentration of 1.2 g/100 mL of C-TiO2, 0.12 g/ 100 mL of D-TiO2 and 0.10 g/100 mL of modified MD-TiO2 for a definite concentration of RRR. However, RRR shows adsorption on TiO2 samples except C-TiO2. Again, the photodegradation efficiency is inversely affected by the dye concentration. Thus, the removal efficiency was found to be influenced by all of the above parameters. The maximum removal efficiency is found at pH 3.0 under sunlight in the presence of modified MD-TiO2,which suggests that MD-TiO2 can be used as an effective material for the removal of RRR instead of C-TiO2 and D-TiO2.

A Data Acquisition System for Solar PV Module with Variable Load
Authors: Rahman Md Habibur , Shams Nasif , Mazumder Gour Chand , Huque Saiful
Published: July 2021

This paper describes the design, development and performance of a locally developed data acquisition system for solar PV module with variable load. The system can automatically change the operating point of a PV module and acquire the output voltage and load current into computer and then analyze. To change the operating point, a variable load has been developed by IRF250 MOSFETs. The current drawn by the load from the PV module is controlled by a staircase voltage, which is developed by a counter and a DAC. The count value of the counter and hence the voltage level of the staircase is changed by an Arduino-based controlling unit. To get the short-circuit current, the PV module is connected in series with a high ampere power supply and the voltage across the PV module is conditioned by a difference amplifier and fed to an ADC channel of the controlling unit. The output current of the PV module has been sensed by a Hall sensor, ACS712, and read by another ADC channel. To make the whole system automatic, a program has been developed using Arduino IDE and loaded in the Arduino board. With the help of this program, the system can measure the current and voltage of the PV module and send to a PC. This acquired data is processed by software and the performance of the PV module is obtained. The system has been developed in laboratory and its performance has been studied. Although, there are some fluctuations in the acquired data but with filtration satisfactory performance is obtained. This instrument can be used for PV module testing purpose.

Human trafficking has received increased media and national attention. Despite concerted efforts to combat human trafficking, the trade in persons persists and in fact continues to grow. This paper describes the relationship and distinction between trafficking and ethnic fragmentation, conflict, internally displaced person by different measures of control. To explain the relationship between these factors, this study uses a Probit regression model. It appears that ethnic conflict leads the internal displacement of individuals from networks of family and community, and their access to economic and social safety nets.

Natural Convection Flow of MHD Micropolar Fluid Along a Vertical Wavy Surface
Authors: Sultana S , Roy Nepal C
Published: July 2021

We study the boundary layer characteristics of natural convection flow of an electrically conducting micropolar fluid along a vertical wavy surface. The dimensionless governing equations have been solved numerically. Results are presented in terms of the local skin-friction coefficient, the local Nusselt number and the local couple stress with the variation of amplitude-wavelength ratio, magnetic parameter, vortex viscosity parameter and spin-gradient viscosity parameter. Due to increase of the amplitude wave-length ratio, the skin-friction and the couple stress are found to decrease whereas the Nusselt number increases. The skin friction and the couple stress increase but the Nusselt number decreases for increasing values of vortex viscosity parameter. In addition, when the spin-gradient viscosity is increased, the maximum values of the Nusselt number and the couple stress significantly increase but the skin-friction decreases. The magnetic parameter considerably reduces the skin-friction, Nusselt number and couple stress.

Authors: Begum Salma , Yeasmin Humaira , Debnath Tapas , Shaikh AA , Bakshi Pradip K
Published: July 2021

Rabeprazole (RPZH) (available as rabeprazole sodium, RPZNa) is a proton pump inhibitor (PPI), widely used for the treatment of acid-related diseases in the stomach and duodenum. It is a weak base with pKa= 4.9 and show a strong ability to form complexes with transition and nontransition metal ions. Its complexes with Cu(II), Zn(II), Cd(II) and Hg(II) have been synthesized and characterized by solubility, melting point, metal content estimation, IR and UV-Visible spectral analysis, magnetic measurement, thermogravimetric analysis, differential scanning calorimetry and X-ray powder diffraction studies. On the basis of metal contents, the complexes have been formulated as [Cu(RPZ)(H2O)Cl], [Zn(RPZ)2], [Cd(RPZ)2].2H2O and [Hg(RPZ)2].H2O. Rabeprazole sodium (RPZNa) loses Na+ ion in solution yielding a monoanionic RPZ that behaves as a bidentate ligand and coordinates through C-N- and S=O groups with the divalent metal ion. Tetrahedral geometry of all complexes is proposed. Zn(II), Cd(II) and Hg(II) complexes have 1:2 metal to ligand stoichiometry while Cu(II) complex possesses ligand to metal ratio of 1:1. Cu(II) and Zn(II) complexes have also been screened for their antibacterial and antifungal activities against several bacteria and fungi.

Research has been carried out to determine the cell structure of the epidermis and stomata in some mangrove plants in the species Aegiceras corniculatum and Rhizophora apiculata. Descriptive method is used to describe the cell structure of the epidermis and stomata of Aegiceras corniculatum and Rhizophora apiculata and quantitative leaves to calculate the number of stomata, number of epidermis and stomata index based on nail polish on the cross section of epidermal cells on the lower underside of the leaf using a light microscope, while the incision longitudinal to determine leaf thickness between the upper epidermis and the lower epidermis. The results showed that the two mangrove species that grow in the mouth of the Poka and Leahari villages namely Aegiceras corniculatum and Rhizophora apiculata were found to have the same anatomical structure and leaf anatomical characteristics in terms of the shape of epidermal cells, rectangular, octagonal, elongated, and irregular. Aegiceras corniculatum and Rhizophora apiculata have anomositic stomata type because neighboring cells surround the stomata and have the same shape as epidermal cells. Mangrove species in the river estuary of Poka Village have higher number of stomata and smaller epidermal size and lower stomata index than mangrove species in Leahari Village due to the influence of the shade.
