This work proposes an finest mapping from features space to inherited space using kernel locality non zero eigen values protecting Fisher discriminant analysis subspace approach. This approach is designed by cascading analytical and non-inherited face texture features. Both Gabor magnitude feature vector (GMFV) and phase feature vector (GPFV) are independently accessed. Feature fusion is carried out by cascading geometrical distance feature vector (GDFV) with Gabor magnitude and phase vectors. Feature fusion dataset space is converted into short dimensional inherited space by kernel locality protecting Fisher discriminant analysis method and projected space is normalized by suitable normalization technique to prevent dissimilarity between scores. Final scores of projected domains are fused using greatest fusion rule. Expressions are classified using Euclidean distance matching and support vector machine radial basis function kernel classifier. An experimental outcome emphasizes that the proposed approach is efficient for dimension reduction, competent recognition and classification. Performance of proposed approach is deliberated in comparison with connected subspace approaches. The finest average recognition rate achieves 97.61% for JAFFE and 81.48% YALE database respectively.

Number of assembly algorithms have emerged out but due to constraints of genome sequencing techniques no one is perfect. Various methods for assembler’s comparison have been developed, but none is yet a recognized standard. The problem of evaluating assemblies of formerly unsequenced species has not been considered, because mostly existing methods for comparing assemblies are only applicable to new assemblies of finished genomes. For comparing and evaluating genome assemblies we have used QUAST (Quality Assessment Tool). This tool is used to assess the quality of leading assembly software by evaluating quality metrics. Assemblies with a reference genome, as well as without a reference can be evaluated by QUAST tool. For genome assembly evaluation based on alignment of contigs to a reference, it is a modern tool. In this study we demonstrate QUAST performance by comparing several leading genome assemblers on three metagenomic datasets.

Filtered-Orthogonal Division Multiplexing (F-OFDM) is one of the capable alternative candidate modulation methods for 5G communication systems. F-OFDM utilizes the allocated spectrum by having lower side-lobes, which leads to higher spectral efficiency. However, it experiences an elevated peak-to-average power ratio (PAPR). This influences the radio frequency components’ operation mode, such as the power amplifier and the digital-to-analog converter. Also, high PAPR builds the amplifiers to exertion in non-linear regions and enhance the Bit Error Rate (BER). Moreover, Large PAPR guides to spectral spreading and band distortion. Selective Mapping (SLM) provides enhanced PAPR reduction without the data rate loss and also exclusive of the signal distortion. Though, SLM has elevated computational complexity additionally. Numerous procedures have been suggested in the research for OFDM. In this thesis, a modified-SLM using Discrete Sine Transform (DST) is recommended to lessen the PAPR of filtered-OFDM. The idea of a Discrete Sine Transform is de-correlating the data in a sequence by compressed a large amount of signal energy into a few transform coefficients; consequently it provides an improved diminution in PAPR. Furthermore, the BER performance of the system has been enhanced by applying an optimization algorithm called Particle Swarm Optimization (PSO). This proposed model results illustrate that the proposed Modified Selective mapping using Discrete Sine Transform (MSLM-DST) technique can provide a PAPR reduction of about 4.4 dB. Moreover, the PSO improved the system performance as it significantly reduces the BER of the system.

Multi level Authentication means authentication of user at different levels. Attendance system concerns with taking students attendance, with complete efficiency and awareness, this all used to happen in a very conventional way, wherein there were more chances of discrepancy in records. Authentication is a major concern as safety is a priority which proves the validity of the user, when designing a software which stores large amounts of data and which has already existed in the past, and has certain loopholes. To fill these loopholes and to make this process more reliable Multi Level Authentication is used. Multi-Factor Authentication used here have three phases, starting with Login credentials which goes unique even if students share their credentials with their peers their peers won’t be able to login using their phones as IMEI was stored initially during the time of registration. This code is stored in the database without the knowledge of the student. We have the next phase which is OTP generation which is secured using RSA sent to the registered mobile number that is very unique as the OTP is sent only to the registered mobile number. The last phase which ensures the presence of student in the class is QR code scanning, where in a student scans QR code shared by the teacher in the class . After scanning the QR code the attendance gets stored in the database. The purpose of this Attendance system is to overcome the drawbacks of the already existing conventional way which includes marking attendance manually which was a time taking process. By introducing this attendance system using multi level authentication we have established a more advanced, more efficient and more secure unlike conventional attendance system. Multi level authentication can be used in various application where security of the assets is the main concern.

Published: May 2020

Исследуются технологические режимы производства овощного пюре: бланширование в горячей воде, бланширование острым паром (шпарение). Авторами изготовлены опытные образцы согласно технологическим параметрам: для бланширования температура воды составляла 85-100°С (10-15 мин), для шпарения температура пара составляла 105-110°С (5-10 мин). Цель исследования – изучение влияния предварительной тепловой обработки овощного сырья (бланширование и шпарение) на химический состав и антиоксидантную активность готового продукта – пюре. В экстрактах анализируемых образцов определялись фенолы, флавоноиды, антиоксидантная активность по методам DPPH (2,2-дифенил-1-пикрилгидразила) и FRAP (железо-восстанавливающая антиоксидантная способность). Результаты исследования показали, что более щадящим для определяемых показателей является технологическая операция – бланширование при температуре 85-100°С в течении 10-15 мин. При этом лидером по большинству параметров выступает свекольное пюре.

Published: May 2020

В последнее время в мире приобретает популярность плод хлебного дерева (джекфрут), особенно среди вегетарианцев, вследствие того, что его плоды придают энергию из-за наличия в нем простых сахаров (фруктозы и сахарозы), при этом он не содержит жиров и вредного холестерина, что делает его превосходным источником энергии. С целью консервирования данного продукта рекомендовано применение биоразлагаемых полимерных покрытий для повышения сроков годности с максимальным сохранением пищевой ценности. Целью работы является разработка рациональных режимных параметров сушки ломтиков джекфрута с защитным биопокрытием и моделирование тепло- и массопереноса. Для достижения поставленной цели установлены кинетические закономерности процесса конвективной сушки ломтиков джекфрута, как двухслойного объекта и построены кривые скорости удаления воды. При варьировании в рамках технологических ограничений параметров, влияющих на интенсивность обезвоживания, определена, зависящая от их величины удельная производительность процесса и ее рациональное значение. Опираясь на анализ закономерностей протекания процессов переноса тепловой энергии и вещества выявлены их специфические особенности при удалении влаги из двухслойного объекта. Численно решена модель переноса тепловой энергии и вещества и рассчитана эволюция полей температур в образце при сушке. Полученные результаты позволили определить рациональные режимы обезвоживания, обеспечивающие устойчивость на поверхности ломтика нанесенного защитного покрытия, что способствует увеличению сроков его хранения при конечной влажности 25%, а также снижению энергоемкости реализуемого процесса консервации обезвоживанием. Обоснована возможность использования биополимерного покрытия на основе альгината натрия при сушке ломтиков джекфрута.

The deviation of continuous and discrete complex

random variables from the traditional proper and symmetric

assumption to a generalized improper and asymmetric characterization

(accounting correlation between a random entity

and its complex conjugate), respectively, introduces new design

freedom and various potential merits. As such, the theory of

impropriety has vast applications in medicine, geology, acoustics,

optics, image and pattern recognition, computer vision, and

other numerous research fields with our main focus on the

communication systems. The journey begins from the design of

improper Gaussian signaling in the interference-limited communications

and leads to a more elaborate and practically

feasible asymmetric discrete modulation design. Such asymmetric

shaping bridges the gap between theoretically and practically

achievable limits with sophisticated transceiver and detection

schemes in both coded/uncoded wireless/optical communication

systems. Interestingly, introducing asymmetry and adjusting the

transmission parameters according to some design criterion

render optimal performance without affecting the bandwidth or

power requirements of the systems. This dual-flavored article

initially presents the tutorial base content covering the interplay

of reality/complexity, propriety/impropriety and circularity/noncircularity

and then surveys majority of the contributions in this

enormous journey.
Między Platonem a Plotynem. Wątki erotyczne w Dziejach miłości Bożej Teodoreta z Cyru = Between Plato and Plotinus. Erotic motifs in the Religious History of Theodoret of Cyrrhus
Authors: Nadobnik Wojciech
Published: April 2020

In the article, the author examines the importance of erotic terminology for the depiction of the relationship between monk and God in the hagiographical Religious History of Theodoret, bishop of Cyrrhus. He tries to prove that Theodoret made a conscious use of philosophical concepts of Eros in order to make the phenomenon of Syriac monasticism more intelligible for the contemporary pagan intellectuals. In the argument, the author first discusses Theodoret’s knowledge of Plato’s Symposium and Phaedrus, and the Enneads of Plotinus. Secondly, he examines the possible use Theodoret makes of those texts in the six topics where the erotic terminology appears (object and subject of love, contemplation, ascetism, contrition, community).
Modifikasi Alat Pelindung Kaki dalam Mencegah Timbulnya Ulkus Kaki pada Penderita Diabetes Melitus
Authors: Hartanto Hartanto
Published: April 2020

Kaki tersusun atas tulang, otot, sendi, ligamentum, sistem limfe dan sistem neurovaskular yang sangat penting dalam mendukung aktivitas dalam kehidupan manusia. Kaki terdapat di distal tubuh dan memiliki struktur rangka khusus, sehingga pada saat menjalankan fungsinya akan terpapar terhadap lingkungan. Hal ini menyebabkan kaki rentan mengalami trauma, baik dari lingkungan maupun dari dalam tubuh. Ulkus plantar merupakan salah satu komplikasi kronis pada kaki penderita diabetes melitus yang tidak ditangani dengan baik. Terapi medikamentosa masih merupakan pilihan utama pada ulkus plantar, namun tindakan pencegahan merupakan salah satu faktor penting dalam mendukung pemulihan dan pencegahan kejadian ulkus plantar. Pemanfaatan alat pelindung kaki merupakan salah satu bagian dari tindakan pencegahan yang penting. Kaki penderita diabetes melitus mengalami perubahan struktur makro maupun mikro sehingga tidak dapat menggunakan alat pelindung kaki biasa seperti yang digunakan oleh orang sehat. Oleh karena itu, perlu dilakukan modifikasi pada bagian-bagian alat pelindung kaki yang sesuai dengan kebutuhan penderita. Penggunaan modifikasi alat pelindung kaki merupakan salah satu tindak pencegahan yang telah terbukti dapat mengurangi tekanan plantar pada area spesifik di kaki, sehingga kejadian luka baru atau perburukan luka dapat dicegah. Kata kunci : ulkus plantar, modifikasi alat pelindung kaki, tekanan plantar

Temephos 1% atau lebih dikenal dengan abate dulu efektif untuk penanganan larva nyamuk, khususnya larva Aedes aegypti yang merupakan vektor utama dari demam berdarah. Akan tetapi penggunaan yang terus menerus dan tidak terkontrol dapat menyebabkan terjadinya resistensi temephos. Tujuan dari penelitian ini adalah untuk mencari larvasida alami yang dapat digunakan sebagai alternatif atau pengganti temephos, salah satunya adalah buah okra. Penelitian ini merupakan penelitian eksperimental, dengan lima kali pengulangan dan konsentrasi masing-masing 1%,2%,4%,8%, dan 16%, kontrol negatif, dan temephos 1% sebagai kontrol positif, dan dilakukan pengamatan selama 24 jam untuk melihat jumlah kematian larva. Hasil percobaan serbuk buah okra dengan berbagai konsentrasi terhadap larva instar III Aedes aegypti menunjukkan hasil nilai LC50 sebesar 4,143% dan LC90 sebesar 12,778%. Serbuk buah okra dapat bertindak sebagai racun dan bersifat sebagai racun kontak bagi larva Aedes aegypti. Dapat disimpulkan bahwa dosis efektif serbuk buah okra untuk mematikan larva Aedes aegypti adalah 12,778 %.
