Authors: Jabbouri Farah
Published: March 2021

This research intends to study the influence of female empowerment on leadership effectiveness in the UNDP Lebanon. It was once believed that men were the only ones that could fill positions of power and leadership. Even nowadays, women still face great difficulties while obtaining the positions of power in their career and suffer from inequality at work. This study will be looking at the impact of women empowerment and its influence on fulfilling work outcomes and meeting organizational objectives as well as proving that gender equality is the basis of empowerment. The research utilizes mixed methods for conducting interviews and sending online anonymous questionnaires. The results of the interviews show that the UNDP strongly encourages female applicants to apply to power and leadership positions. Upon conducting the study, the distribution of jobs among men and women at the UNDP was shown to be equitable. 52% of the employees are female and 48% are male. Furthermore, the findings show that 50% of the employees that filled the questionnaire have female managers. The online questionnaire shows that the staff are satisfied with the empowerment initiatives at the UNDP and that both men and women are empowered equally.

Published: March 2021

Carbon dioxide (CO2) is one of the corrosive element which exists in oil and gas industries. To prevent CO2 corrosion on carbon steel pipelines, amine-base solvent and caustic solutions are commonly applied. Accordingly, effectiveness of amine base solvent and caustic solutions to reduce risk of corrosion becomes key parameters in determining service lifetime of pipelines made of carbon steel. In this research, the corrosion rate of carbon steel A106 Gr B in amine solutions combined with saturated CO2 gas and caustic solution was studied. The experiments were carried out in static conditions and the Linear Polarization Resistance (LPR) technique was used to measure the corrosion rate (as per ASTM G 5-94). It was found that the corrosion rate in the amine-based solution had shown remarkable results. Somehow, the corrosion rate in an amine-based solvent containing saturated CO2 gas has increased to 200%. The temperature increment to 50°C from room temperature has also increased the corrosion rate. Meanwhile, the caustic addition in amine solution has reduced the corrosion rate of carbon steel.

Published: March 2021

Red blood cell (RBC) aggregation is the reversible adhesion of RBCs among themselves. We previously reported a positive correlation between blood glucose level and the degree of RBC aggregation (the brightness of the B-mode image). In the present study, we investigated the contribution to the brightness according to the deviation from the central axis in measurements along with the long-axis view of the vein. The results show that the brightness changed significantly for a slight change in the lateral position in the short-axis image. We found that the stability of the measurements was not guaranteed in the long-axis view and estimated the correct analysis window range for the short-axis view.

Authors: Rathore Virendra Singh , Mohammed Sabah
Published: March 2021

The world that we live in today has so many languages that we speak throughout. Out of more than the six thousand languages that are spoken around the world, the most common is the English language. But there are people who do not understand it. When we speak of medications, the language barrier becomes riskier. If consumers are not able to understand the warning labels on the medicines, it might prove fatal to life. So it seems important that there be a tool or an application that would help them recognize and decode the warnings and/ or the instructions that are printed the medication pill containers. This tool will prove very useful for patients across the world and also people who consume any kind of medication without understanding the procedures/ risks that are specific to those medications.

Visible Light Communication with Input-Dependent Noise: Channel Estimation, Optimal Receiver Design and Performance Analysis
Authors: YASEEN MAYSA , Alsmadi Malek , Canbilen Ayse E. , Ikki salama
Published: March 2021

In this paper, single-input single-output (SISO) visible light communication (VLC) subject to signal-dependent shot noise (SDSN) is investigated. We discuss both channel estimation and data transmission. In the former, we introduce least square (LS) and maximum likelihood (ML) estimators. Moreover, we derive the Cram´er–Rao lower bound (CRLB) of the channel estimation error. With regard to data transmission, we present optimal and sub-optimal receiver designs and discuss their bit error rate (BER) performance. In particular, a closed-form expression of the BER is derived for a sub-optimal receiver using the on-off-keying (OOK) modulation technique. An approximated expression is then derived for the optimal receiver. Our analysis shows that the CRLB performance does not have a linear relation with the SDSN, thermal noise, or the fading channel. On the other hand, the SDSN has a dramatic effect on the channel estimation error bound, and it can degrade the BER performance. Increased performance degradation can also be noticed due to the joint effects of the channel estimation error and SDSN.

Published: March 2021

Abstract—This paper introduces a novel algorithm for suppresion of phase current harmonics in three-phase brushless dc motors caused by non-ideal back-emf waveform and dead-time effects. Proposed feedback acquisition chain obtains an exact information on all the relevant harmonics within each period of the fundamental. Design of the harmonic regulator based on the internal model control principle is given. The paper outlines the relevant details of implementation and the results of verification performed by both computer simulations and experimentally, using a laboratory prototype machine. Experimental results conducted in presence of non-sinusoidal back-emf and with erroneous dead time compensation prove the ability of the proposed solution to remove the stator current harmonics quickly, in just two fundamental periods.

This paper reports on one of the findings of a study undertaken to investigate the coping strategies used by small-scale sugarcane growers in Bungoma County, Kenya. A descriptive survey design was used. A multi-stage sampling procedure was employed in the selection of the divisions, villages, key respondents, and sugarcane farmers to be interviewed. Primary data were collected using questionnaires from 100 small-scale sugarcane growers’ household heads from Bumula Sub-County. Data were collected during the month of December 2016.  Qualitative data collected were analysed thematically. Quantitative data was analysed using regression in SPSS version 23 and Microsoft Excel. Results from small-scale sugarcane farmers in Bumula Sub-County revealed a declining farmers’ participation in sugarcane farming activities in the area. Coping strategies identified included off-farm income-generating activities, sale of sugarcane by-products and non-contracted cane farming. Significance test qualification was based on a percentage of adjusted R2 and within 0.3 to 0.7 ranges for Beta weight value.  The correlation coefficient (R-value) for the model was 0.362, indicating a moderately positive relationship between variables. The coefficient of determination (R2) was found to be 0.284 (28.4%). Adopted coping strategies accounted for 28.4% variability in the declining farmers’ participation in sugarcane farming. This result suggests the existence of other factors that explain the remaining 71.6% of the variation in the declining farmers’ participation. Farmers should enhance both on-farm and off-farm income-generating activities, sugarcane by-products value addition, and non-contracted cane farming in order to reverse the outcome and result in an enhanced farmers’ participation in sugarcane farming activities by 36.2%

However, the use of shallots (Allium cepa L.) was limited to its meat only, meanwhile the skin is not utilized. Shallot (Allium cepa L.) peel itself contains flavonoids, polyphenols, saponins, terpenoids and alkaloids. One of the utilization of shallot (Allium cepa L.) peel is by innovating it into flour to make crackers. The aims of this study were to determine the physical test and total flavonoids content of crackers from the skin of shallot (Allium cepa L.). Methods: This study used descriptive quantitative method. The observations of crackers quality was conducted in this study are in accordance with the parameters of crackers SNI 2973: 2011 and RSNI 2973: 2018, which include water content tests, acid insoluble ash content tests, organoleptic tests, hedonic tests, qualitative identification and quantitative analysis of flavonoids. Results: The average percentage of water content of crackers was 2%. The average percentage of insoluble acid ash content of crackers was 0.3%. The organoleptic crackers test results have a special shallots aroma, dark brown in color, and taste delicious. The hedonic test results showed respondents liked the aroma, color, and taste of crackers. Crackers from shallot (Allium cepa L.) peel flour contain positive flavonoid compounds. Conclusion: The determination of total flavonoids content in crackers shallot (Allium cepa L.) peel flour was conducted based on AlCl3 method with total flavonoids expressed in QE (Quercetin equivalent) at the maximum wavelength of 435 nm. The result showed that the average content of flavonoid total is 4,5591 mgQE/g extract.

Interference Cancellation for MIMO Systems Employing the Generalized Receiver with High Spectral Efficiency
Authors: Tuzlukov Vyacheslav
Published: March 2021

In this paper, we investigate the performan-ce in terms of symbol error probability (SEP) of multipleinput multiple-output (MIMO) systems employing the ge-neralized receiver with high spectral efficiency. In particular, we consider the coherent detection of M-PSK signals in a flat Rayleigh fading environment. We focus on spectrally efficient MIMO systems where after serial-to-parallel con-version, several sub-streams of symbols are simultaneously transmitted by using an antenna array, thereby increasing the spectral efficiency. The reception is based on linear mi-nimum mean-square-error (MMSE) combining, eventually followed by successive interference cancellation. Exact and approximate expressions are derived for an arbitrary nu-mber of transmitting and receiving antenna elements. Sim-ulation results confirm the validity of our analytical meth-odology.

Dengan mesin penyejuk udara ini pengaturan udara dalam ruangan akomodasi kapal dapat dilakukan sesuai dengan suhu ruang akomodasi yang diinginkan. Tujuan dari penelitian ini adalah untuk mengetahui mengapa tidak tercapainya suhu ruangan akomodasi yang diharapkan, faktor apa apa yang membuat tekanan kondensor menjadi tinggi dan penyebab penanganan air conditioner di kapal tidak optimal. Sistem air conditioner kurang mendapat perawatan dan pemeliharaan yang teratur, sehingga proses pendinginan terganggu. Sistem Air Conditioner belum bekerja dengan baik karena kurangnya dilakukan pengawasan-pengawasan yang rutin dan pengecekan terhadap temperatur, tekanan dan bagian-bagian pendukung lainnya dari sistim. Masinis kurang pengetahuan baik teori maupun praktek, dan belum berpengalaman sehingga gangguan-gangguan yang terjadi sebetulnya tidak seberapa, namun menjadi kerusakan yang lebih besar dan akhirnya mengganggu kinerja sistem air conditioner secara keseluruhan. Belum dilaksanakannya perawatan dan pemeliharaan yang teratur dan terencana sehingga setiap kegiatan tidak tercatat (di dalam log book) sehingga sulit bagi seorang Masinis untuk menganalisa kerusakan yang terjadi dan apa tindakan selanjutnya yang harus dilakukan
