In industries, the completion time of job problems is increased drastically in the production unit. In many existing kinds of research, the completion time i.e. makespan of the job is minimized using straight paths which is time-consuming. In this paper, we addressed this problem using an Improved Ant Colony Optimization and Tabu Search (ACOTS) algorithm by identifying the fault occurrence position exactly to rollback. Also, we used a short term memory-based rollback recovery technique to roll back to its own short term memory to reduce the completion time of the job. Short term memory is used to visit the recent movements in Tabu search. Our proposed ACOTS-Cmax approach is efficient and consumed less completion time compared to the ACO algorithm.

Implementing cognitive radio sensor nodes in wireless sensor networks introduced a smart combination called cognitive radio sensor network (CRSN) which creates new challenges in the design of network topology. Conserving the nodes energy helps to extend the lifetime of the network. This stands as an important criterion while designing any algorithm. In order to achieve the same, two important criteria are to be considered – the communicating distance between the nodes or node to base station and proper spectrum sharing technique. In the proposed work, Energy Reckoning Distance-Based Clustering (ERDBC) algorithm, both the criterion is taken into consideration and designed in order to increase the lifetime of a cognitive radio sensor network. In the ERDBC algorithm, the whole network area is divided into three regions according to the distance and the cluster heads are elected based on energy, distance and common channel creates a greater impact on retaining the nodes energy. Also, implementing multi-hop routing using proper spectrum sharing technique helps to avoid data collision and retransmission thereby; the energy consumption of the nodes are reduced to a greater extent. The performance of the proposed ERDBC algorithm is measured on the basis of residual energy, throughput, channel usage, first node death, last node death, and network lifetime, and compared with the already existing LEACH, CogLEACH, LEAUCH and CEED algorithms. Thus the network lifetime of the proposed ERDBC algorithm is 78.18% more than LEACH, 73.6% more than CogLEACH, 29.88% more than CEED and 17.98% more than LEAUCH algorithms.

The domain of image signal processing, image compression is At Contribution of hybrid protocol has been gaining importance owing to more demands of energy efficiency among the communicating nodes in Wireless Sensor Network (WSN). Review of existing literatures shows that hybrid MAC protocols has been not been evaluated over heterogeneous environment in WSN with no much consideration of temporal factors connected to it. Hence, the proposed system introduces a novel extensive hybrid MAC protocol (EH-MAC). The system introduces a mechanism where time synchronization with respect to assigned dynamic slots are considered followed by inter-synchronization of network. Apart from this, a relay node selection process has been used uniquely considering the state of static and mobile sensor nodes in the analysis environment. The proposed system also introduces an unique selection of node unlike conventional MAC protocols which offers a capability to control any form of idle listening within WSN. The simulated outcome of the proposed system has been found to offer higher residual energy, faster response time, lower memory consumption, and optimal throughput delivery performance in comparison to standard existing hybrid MAC schemes in WSN.

Concrete is quite popular material in today’s era. It has a history of evolution at different stages. In modern time we can see concrete made structures all around rather it is Residential Buildings, flyovers, industrial building, water carrying structures like elevated water tanks etc. It is strong under compression yet weak under tension. To counter the weakness in tension we have to add something which can bear tensile force subjected to concrete ex: steel bars and to resist cracks we have to add fibres which gave some additional benefits along with increasing cracking strength it also improve tensile, flexural, shear, torsional strength and also improves its durability etc. Present study is to ascertain the behavior of steel fibre reinforced concrete with varying percentage of fibres. The experiments were conducted on concrete mixes of M20 grades. Spring fibres of length 25mm and diameter of 0.1mm (cross-section) and spring diameter 8mm with aspect ratio of 31.25 was used. Concrete was reinforced with different percentage of above mentioned fibres i.e. 0%, 0.5%, 1%, 1.5% and 2% by weight of cement. A total of 15 cubes of standard size 150mm*150mm*150mm, 15 cylinders of 150mm diameter and 300mm height were cast and 15 beams of 100mm*100mm*500mm were cast and tested under two point loading to find flexural strength. The experimental program involved the evaluation of the compressive strength of concrete cubes under uniaxial compression. The cylinders were tested for their splitting tensile strength and the tensile strength was recorded under uniaxial compression testing machine. Flexural test on plain concrete and SFRC-Standard beam of size 100mm*100mm*500mm Were supported symmetrically over a span of 420 mm and subjected to two points loading till failure of the specimen.

Agriculture is one of the most significant economic activity. They are many ways that leads to the low productivity of agriculture, but the best method to protect the crop is by detecting the diseases in the early stage. In most of the cases diseases are caused by pest, insects, pathogens which reduce the productivity of the crop at the large scale. If pests are detected on the leaves then, precautions should be taken to avoid huge productivity loss at the end. The main objective of this paper is to identify the pests using image processing techniques like Gaussian blur, segmentation, watershed separation, morphological operations. These techniques are more efficient and less time consuming while identifying the pests over the leaf image with high intensity.

Main focus of this research work is aims towards the nonlinear analysis of human cardiac muscle by describing function technique and finding stability using lyapnuov stability theory. The nature of cardiac muscle can be modeled by mass, spring with a damper where for simplicity spring and damper are considered a linear element. In reality, it has been observed that, the characteristics of spring and damper are not linear rather nonlinear. Not only that, transportation delay (non-zero reaction time) or lag phase of cardiac muscle plays an important role to make the overall model nonlinear. The range of transportation delay for which the system is stable has been calculated here to ensure the presence of dead zone type nonlinearity in cardiac muscle. In this paper a nonlinear characteristics of the model has been analyzed considering dead zone combined with saturation. The describing function technique is used here to represent the nonlinearity. A converging stable limit cycle has been found after the analysis. Finally, lyapnuov stability theorem is applied on our proposed model and it has been that the system is asymptotically stable in the sense of lyapnuov.

In urban areas where land is limited and buildings are closely spaced, deep excavations are necessary for the construction of surface and sub-surface facilities. Therefore, there is a concern that soil excavations resulting in a ditch or a trench adjacent to a building may adversely affect the response of nearby buildings when earthquakes occur. In this paper, the results of experimental study of building frame models in close proximity of excavations and subjected to artificial excitations are presented through a series of shake table tests. The study has been conducted to investigate the effects of the size and offset distances of excavations on the response of the building frame models founded on different types of foundation systems. It is observed that the width, depth and offset distance of the trench has a significant influence on the response of the building frame. It is seen that pile foundation with sufficient embedment depth produces less displacement at the top of the building as compared to other foundation systems.

Authors: Maimunah Maimunah
Published: December 2019

Tujuan dari penulisan artikel ini memberikan pengetahuan tentang kedudukan hak waris anak dari pernikahan incest dalam perspektif fiqh. Pernikahan Incest merupakan pernikahan sedarah yang dilarang dalam agama Islam sehingga perlu dibatalkan pernikahan tersebut sebagaimana diatur dalam surat an-Nisa ayat 23. Di dalam Undang-Undang Perkawinan, larangan perkawinan incest diatur pada pasal 8, sedangkan di dalam Kompilasi Hukum Islam terdapat pada pasal 39. Akibat dari pernikahan incest itu, tentu memiliki akibat hukum terhadap status kewarisan anak dari perspektif fiqih. Anak yang dilahirkan pernikahan incest tidak memiliki kesalahan yang dilakukan oleh kedua orang tuanya, sehingga perlu dilakukan perlindungan atas hak-haknya. Anak perlu mendapatkan perlindungan sebagaimana diatur dalam al-Qur’an dan perundang-undangan. Bila terjadi suatu sengketa dalam rumah tangga, baik ibu maupun bapak tetap berkewajiban memelihara dan mendidik anak-anaknya semata demi kepentingan si anak meskipun anak tersebut anak yang lahir dari hasil hubungan incest. Hak waris anak incest tidak diatur dalam hukum Islam, karena hukum Islam hanya mengenal anak sah dan anak tidak sah (anak zina). Jika keduanya sama-sama tidak mengetahui hubungan sedarah mereka, maka hukum yang berlaku adalah seperti konsep hilangnya beban hukum atas tiga orang, orang yang khilaf (QS. Al Ahzab: 5), lupa dan orang yang dipaksa. Jika keduanya tidak mengetahui adanya cacat nikah dari aspek larangan pernikahan, maka hubungan suami-isteri yang lalu adalah sah dan tidak dianggap sebagai perbuatan zina. Dan anak hasil perkawinan mereka tetap bernasab kepada bapaknya dan juga berhak mewaris kepada bapak dan ibunya.

Demokrasi telah dimaknai sebagai sebuah sistem politik yang menuntut adanya perubahan masyarakat menjadi sebuah konsep peradaban. Hal ini merupakan salah satu cara untuk mengharmonisasikan hubungan kita dan pengkelompokannya sehinggga semua itu akan dengan sendiri menjadi lebih cepat berkembang menjadi gagasan kebebasan, kesamaan, dan keadilan. Dimana berhasil dijalankan, demokrasi dapat disebut sebagai pemerintahan dari rakyat yang dibuktikan oleh perwakilan atas pilihan sendiri terhadap kepentingan dan keinginan mereka untuk mengkontrol. Ketika Woodrow Wilson, seorang Presiden Amerika Serikat selama perang dunia pertama, gagasan tenang “selamatkan demokrasi”, dia berfikir terhadap kebutuhan untuk menjaga sebuah lingkungan yang dapat membantu terhadap tumbuhnya peradaban demokrasi yang matang.

Perlindungan Hak Individu Terhadap Kebebasan Menyampaikan Pendapat Melalui Informasi Elektronik dalam Perspektif HAM
Authors: Fajar Ahmad
Published: December 2019

Perkembangan teknologi saat ini menimbulkan masalah yang besar terhadap hak individu dalam menyampaikan pendapat. Secara universal Hak Asasi Manusi (HAM) telah menjamin kebebasan menyampaikan pendapat dalam segala aspek kehidupan, tetapi saat ini banyak pengguna terjerat kasus pidana karena telah menyampaikan pendapat dengan media teknologi. Dalam hal ini Undang-Undang Nomor 19 Tahun 2016 tentang perubahan Undang-Undang Nomor 11 Tahun 2008 tentang Informasi dan Transaksi Elektronik sering dijadikan alat untuk menghakimi individu jika menyampaikan pendapat yang kritis. Menyampaikan pendapat secara obyektif dan kritis semestinya tidak dapat dipidanakan. Regulasi telah memberikan batasan-batasan dalam menyampaikan pendapat agar hak individu dapat dipenuhi. Regulasi  tersebut tetap menjunjung tinggi nilai HAM agar terwujud keselarasan antara hak dan kewajiban asasi.Kata kunci: Hak individu, Pendapat, Informasi Elektronik, Hak Asasi Manusia (HAM)

Kemajuan ilmu pengetahuan dan teknologi dapat membawa banyak pengaruh terhadap perubahan perilaku dan kebiasaan masyarakat. Hal ini membuat masyarakat membutuhkan sesuatu yang cepat, mudah dan simpel untuk mendukung setiap kegiatan mereka, begitu juga dalam hal pembayarannya. Sistem pembayaran yang lebih aman, cepat dan efisien tersebut terdapat pada pelayanan Go-Pay yang disediakan oleh Go-Jek. Sistem pembayaran melalui Go-Pay ini merupakan solusi yang sangat dibutuhkan oleh masyarakat. Akan tetapi, terdapat sesuatu yang agak janggal apabila dilihat dari perspektif ekonomi syariahnya. Dengan menggunakan pendekatan normatif dan analisis data kualitatif, hasil dalam penelitian ini berkesimpulan bahwa pembayaran menggunakan saldo Go-Pay pada aplikasi Go-Jek dapat digunakan oleh masyarakat yang beragama Islam dengan catatan bahwa Go-Pay harus sesuai dengan prinsip-prinsip syari’ah yang terhindar dari ribawi, gharar, maysir, tadlis, risywah, israf, dan transaksi atas objek yang haram atau maksiat. Selain itu, adanya Go-Pay ini termasuk dalam perlindungan terhadap harta (hifdz al mâl) dan berdampak positif bagi pergerakan perekonomian Indonesia.

Published: December 2019

Kemampuan hantar kabel listrik ditentukan oleh nilai KHA (Kemampuan Hantar Arus) yang dimiliki oleh material konduktor. Di sisi lain, daya hantar konduktor sangat dipengaruhi oleh jenis bahan, luas penampang, serta  nilai tahanan yang dimiliki oleh bahan konduktor. Pada penelitian ini akan dilakukan pembuatan bahan konduktor untuk kabel listrik dengan memanfaatkan  deposit tembaga dari limbah PCB dan scrap dari sisa machining. Penelitian yang dilakukan meliputi peleburan deposit dan scrap tembaga menjadi ingot untuk selanjutnya dilakukan pengujian komposisi kimia dan nilai tahanannya. Hasil uji yang diperoleh dibandingkan terhadap nilai kadar Cu dan hambatan dari kabel komersial yang beredar di pasaran. Hasil pengujian  menunjukkan bahwa bahan konduktor dari deposit dan scrap tembaga mempunyai kandungan tembaga (Cu) sekitar 92% dan nilai tahanan 0,4-0,6 mΩ. Nilai tersebut memiliki kualitas yang lebih baik apabila dibandingkan  dengan konduktor kabel listrik yang beredar di pasaran dengan kandungan tembaga (Cu) antara 86%-97% dan nilai tahanan 8-11 mΩ.Kata kunci: konduktor, kabel listrik, deposit, scrap, tembaga

Introduction: Intestinal anastomosis consist of surgical procedures which there is an anastomotic line between two intestinal segments in order to reconstruct or divert the digestive transit. However, several complications may result from this surgical procedure.

Objective: Present, describe and discuss the findings of the literature regarding substances capable of reducing injury and possible complications of intestinal anastomoses.

Method: The data were collected by literature review using the descriptors: "intestinal anastomoses", "antioxidants"; and as basis articles published in the published Scientific Electronic Library (Scielo), Lilacs, MedLine and Pubmed databases. Inclusion criteria were original and review articles published in full in the online form in the Portuguese, Spanish and English languages, using the descriptors mentioned above in the respective languages.

Results: Scientific articles were collected, in which 38 papers were included in the inclusion criteria.

Conclusions: The major parts of substances described in the present study demonstrated be statistically relevant results and the capacity to optimize the anastomotic healing.
The Chemical Signatures of Planetary Engulfment Events in Binary Systems
Authors: Nagar Tushar , Spina Lorenzo , Karakas Amanda I.
Published: December 2019

Planetary engulfment events involve the chemical assimilation of a planet into a star’s external layer. This can cause a change in the chemical pattern of the stellar atmosphere in a way that mirrors the composition of the rocky object engulfed, with the refractory elements being more abundant than the volatiles. Due to these stellar chemical changes, planetary engulfment events can render the process of chemical tagging potentially inaccurate. A line-by-line differential analysis of twin stars in wide binary systems allows us to test the chemical homogeneity of these associations with typical individual stellar Fe i uncertainties of 0.01 dex and eventually unveil chemical anomalies that could be attributed to planetary engulfment events. Out of the 14 systems analyzed here, we report the discovery of the most chemically inhomogeneous system to date (HIP 34407/HIP 34426). The median difference in abundances of refractory elements within the pair is 0.19 dex and the trend between the differential abundances and condensation temperature suggests that the anomaly is likely due to a planetary engulfment event. Within our sample, five other chemically anomalous systems are found.
Modeling Imbalanced Collisionless Alfvén Wave Turbulence with Nonlinear Diffusion Equations
Authors: Miloshevich G. , Passot T. , Sulem P. L.
Published: December 2019

A pair of nonlinear diffusion equations in Fourier space is used to study the dynamics of strong Alfvén wave turbulence, from MHD to electron scales. Special attention is paid to the regime of imbalance between the energies of counter-propagating waves commonly observed in the solar wind (SW), especially in regions relatively close to the Sun. In the collisionless regime where dispersive effects arise at scales comparable to or larger than those where dissipation becomes effective, the imbalance produced by a given injection rate of generalized cross-helicity (GCH), which is an invariant, is much larger than in the corresponding collisional regime described by the usual (or reduced) magnetohydrodynamics. The combined effect of high imbalance and ion Landau damping induces a steep energy spectrum for the transverse magnetic field at sub-ion scales. This spectrum is consistent with observations in highly Alfvénic regions of the SW, such as trailing edges, but does not take the form of a transition range continued at smaller scales by a shallower spectrum. This suggests that the observed spectra displaying such a transition result from the superposition of contributions originating from various streams with different degrees of imbalance. Furthermore, when imbalanced energy injection is supplemented at small scales in an already fully developed turbulence, for example under the effect of magnetic reconnection, a significant enhancement of the imbalance at all scales is observed.
