An Implementing A Continuous Authentication Protocol To Improve Robustness Security Threats On IoT Using ESP8266

The Internet of Things (IoT) is a network of physical things that are outfitted with sensors, software, and other technologies that are able to communicate and exchange data with other devices and systems over the Internet. Because of the diversity of their surroundings, IoT systems are sensitive to network attacks. The IoT could be the source of these dangers and attacks. There are a lot of devices that communicate with each other via the IoT, and one of the most critical components of this is to maintain IoT security. IoT devices are a prime target for attackers and pose a serious risk of impersonation during a call. Proposals to prevent session hijacking in device-to-device communication are made in this research study. User-to-device authentication relies on usernames and passwords, but continuous authentication doesn't. This protocol relies on device features and contextual information. Moreover, this protocol reduces the synchronization losses using shadow IDs and emergency key. In addition, the protocol’s robustness will be tested by providing security and performance analysis

Draft measurement of five tyne duck foot plough in clay soil

In the present study, the draft requirement of five tyne duck foot plough was studied on clay soil for different soil moisture content, depth of operation and forward speed of tractor using a specially designed three-point hitch dynamometer.  The designed dynamometer was matched with the tractors having category II or III hitch systems. The data acquisition system adopted for the dynamometer had NI WSN-3214 Strain Nodes, NI 9792 WSN real-time Gateway and NI LAB View 2013 software. A data logger program was developed for the three-point hitch dynamometer. The investigation was carried out at that three levels soil moisture content (10-13%, 14-16% and 17-20%), at three different depth of operation (15, 20 and 25 cm) and three levels of the forward speed of tractor (3, 5 and 7 km h-1). The designed dynamometer performed well in all the levels of the experiment. The results showed that draft force required for five tyne duck foot plough was increased (408 kg) with an increase in soil moisture content (17-20%), whereas it was increased (408 kg) with an increase in depth of operation (25 cm) and forward speed of tractor (7 km h-1). The suitable sweep, the forward speed of operation, depth of operation and soil moisture content that influenced the draft force and energy consumption for tillage operation of duck foot type plough were identified and developed duck foot plough was better coverage with better soil operation.              

Optimal Sizing and Placement of Solar Cell Distributed Generator Suitable for Integrated Power System Environment

A novel fuzzified Clustered Gravitational Search Algorithm (CGSA) has been employed for solving multi-objective problem formulated for solar based distributed generation. Optimal sizing and placement of solar distributed generation is considered. High solar penetration can lead to high-risk level in power system reliability. In order to maintain the system reliability, solar power dispatch is usually restricted based on the reliability level of the system. Two conflicting objective functions such as power loss and reliability level of the system are also considered for solving optimal placement of solar distributed generation (SDG). Binary coded CGSA is employed for solving optimal placement of SDG and sizing is determined using real coded CGSA. The fuzzy membership function for each objective is designed and multi-objective optimal placement problem has been presented. The proposed method is validated on IEEE standard 69-bus radial distribution networks. The efficiency of the proposed optimization technique is validated by comparing the results with other results available in the existing articles

Metabolic Syndrome and the Management : An appraisal with Siddha System of Medicine

Visceral obesity syndrome also known as metabolic syndrome X is the bunch of medical conditions characterised by hypertension, hyperglycaemia, dyslipidemia and atherosclerotic cardiovascular disease affecting, nearly 240 million people worldwide. In India nearly 10000 people were affected per year and overall it goes on escalating steadily due to amplified adulterated human behaviours. There is a need of exigency at this juncture by knowing its complex pathology to condense human anguish and financial load. Siddha system of medicine primarily describes as it may arise due to provocation of the humours of the body. When our moral code of demeanour is deprived including intemperance and deficit physical activity, there is a flawed tissue metabolism leading to metabolic syndrome (MS). Classical books of Siddha were used for literary survey and databases were also analysed with the prime terminology “Metabolic syndrome” for this systemic review. The speculative backdrop, broad set of strategy in aetiology, pathogenesis and management of MS are discussed at extent through Siddha system, in the paper which would be creditable in managing in an effectual and gainful approach

SPARE PARTS INVENTORY OPTIMIZATION FOR AUTO MOBILE SECTOR

In this paper the objective is to determine the optimal allocation of spares for replacement of defective parts on-board of a usage. The minimization of the total supply chain cost can only be achieved when optimization of the base stock level is carried out at each member of the supply chain. A serious issue in the implementation of the same is that the excess stock level and shortage level is not static for every period. This has been achieved by using some forecasting and optimization techniques. Optimal inventory control is one of the significant tasks in supply chain management. The optimal inventory control methodologies intend to reduce the supply chain cost by controlling the inventory in an effective manner, such that, the SC members will not be affected by surplus as well as shortage of inventory. In this paper, we propose an efficient approach that effectively utilizes the Genetic Algorithm for optimal inventory control. This paper reports a method based on genetic algorithm to optimize inventory in supply chain management. We focus specifically on determining the most probable excess stock level and shortage level required for inventory optimization in the supply chain so that the total supply chain cost is minimized . So, the overall aim of this paper is to find out the healthy stock level by means of that safety stock is maintained throughout the service period. Keywords: genetic algorithm, optimization, Inventor

Transition metal titanium (Ti) doped LaFeO3 nanoparticles for enhanced optical structural and magnetic properties

A series of LaFe1−xTixO3 (x = 0.0, 0.2, 0.4, 0.6 and 0.8) nanoparticles have been successfully synthesized by simple co-precipitation technique. The synthesized samples (calcined at 800° C/3hr) were characterised for structural, optical and magnetic properties. Structural phase formation of the crystal shows orthorhombic planes of these samples phases. The average crystallite size (Dc) is decreasing with a dopant and found to be varying between ∼ 9 and 25 nm. Tailored surface morphology was analyzed using scanning electron microscope (FESEM) and transmission electron microscopes (TEM) with selected area electron diffraction pattern (SAED) also confirms the evolution of orthorhombic phases. Diffuse reflectance spectra (DRS) are recorded to evaluate the variation of optical band gap (Eg) upon titanium doping into the LaFeO3 system. The obtained results attributed that Eg values are increasing with dopant altering between 2.05 and 2.61 eV. The metal oxide (M - O) stretching vibrations and few functional groups are detected from infrared spectra (IR). The weak ferromagnetic behaviour is observed from hysteresis loop behaviour. Additionally, the large hysteresis loop behaviour induces no saturation up to 15 kOe in nanoparticles coercivity (Hc) and anisotropy constants (K1) are eventually decreasing with ‘x’ values

Hukum, Profesi Jurnalistik Dan Etika Media Massa

Dalam kajian hukum dan media massa, moral dan etika tersebut dikaitkan pada kewajiban para jurnalistik antara lain seperti; pelaksanaan kode etik jurnalistik dalam setiap aktivitas jurnalistiknya, tunduk pada institusi dan peraturan hukum untuk melaksanakan dengan etiket baiknya sebagaimana ketentuan-ketentuan di dalam hukum tersebut yang merupakan perangkat prinsip-prinsip dan aturan-aturan yang pada umumnya sudah diterima dan disetujui oleh masyarakat. Sehubungan dengan hal itu, prinsip etika bagi profesi jurnalistik memberikan dasar hukum bagi pengelolaan pemberitaan di media secara tertib dalam hubungan antar subyek hukum.Pada perkembangan di institusi media di Indonesia, aspek kepemilikan saham di media (kepemimpinan), ekonomi dan pemasaran media akan sangat menentukan ideologi yang diusung media, di mana ideologi tersbeut jika mengarah pada pendekatan ekonomi politik media akan memunculkan pelaku media yang kurang akrab dengan etika komunikasi. Etika komunikasi di sini ditempatkan hanya sebagai instrumen belaka dan menjadi kurang bermakna dalam menentukan isi program, kualitas program serta penghormatan pelaku media terhadap hak asasi manusia yang direpresentasikan pada individu sebagai sumber informasi. Pilihan ini menimbulkan etika komunikasi pada pelaku media dianggap sudah mengalami reduksi. Pelaku media sebagai profesi telah mengambil jalan pintas dengan mengacu asas manfaat lebih mengutamakan asas manfaat dalam peliputan dan pemberitaannya, yang sekaligus paradoks dengan etika profesi yang diembannya. Diperparah lagi ketiadaan penghormatan atas asas praduga tak bersalah atas nama demi kepentingan publik untuk memperoleh informasi, akan semakin menjadikan media massa dan pelaku media sebagai pribadi-pribadi yang dominan dalam merekonstruksi dan memanipulasi realitas sosial.Hingga di sini pilihan terhadap kecenderungan pemaknaan pendekatan ekonomi politik atau pendekatan etika, sebenarnya keduanya tidak memiliki implikasi hukum yang kentara, semuanya dikembalikan kepada masing-masing pribadi yang terlibat dalam aktivitas di institusi media massa

Ruthenium(II) 8-quinolinolates: Synthesis, characterization, crystal structure and catalysis in the synthesis of 2-oxazolines

New octahedral ruthenium(II) complexes (1e4) have been synthesized from the reaction of ruthenium(II) precursors [RuHCl(CO)(EPh3)3] (E ¼ P or As) with the bidentate Schiff base ligands, 2-((2,6-dimethylphenylimino)methyl)quinolin-8-ol (L1) and 2-((2,6-diisopropylphenylimino)methyl)quinolin-8-ol (L2) in ethanol. These complexes have been characterized by elemental analyses, IR, UVeVis, 1H, 13C and 31P NMR and ESI-Mass spectroscopy. The molecular structure of the complex [RuCl(CO)(PPh3)2(L2)] (2) was determined by single-crystal X-ray diffraction, which reveals a distorted octahedral geometry around ruthenium(II) ion. The catalytic activity of the new complexes was evaluated for the condensation of nitriles with ethanolamine under solvent free conditions. The processes were operative with aromatic and heteroaromatic nitriles and tolerated several substitutional groups. The studies on the effect of substitution over ligands, coligands, reaction time, temperature and catalyst loading were carried out in order to find the best catalyst in this series of complexes and favorable reaction conditions. A probable mechanism for the catalytic condensation of nitrile has also been proposed. The catalyst was recovered and recycled up to five times without significant loss of its activity

In silico analysis of lipopolysaccharide and β-1, 3-glucan binding protein (LGBP) gene from the haemocytes of Indian white shrimp Fenneropenaeus indicus

Lipopolysaccharide and β-1,3-glucan binding protein (LGBP) gene are involved in the pattern recognition mechanism of invertebrates, it induces the cell and humoral mediated immune responses like encapsulation, phagocytosis, nodule formation, clotting, synthesis of antimicrobial peptides and activation of the prophenoloxidase (proPO) system. The current study focuses to model the three-dimensional structure of novel immune related gene LGBP from the Indian white shrimp Fenneropeneaus indicus (F.indicus) by in silico homology modeling and its motif prediction. Fenneropeneaus indicus lipopolysaccharide and β-1,3-glucan binding protein (Fein-LGBP) consists of glycosylated regions which come under the glucanase family. Two conserved putative integrin-binding motif (cell adhesion sites), bacterial glucanase motif (GM) and two polysaccharide recognition motifs for the polysaccharide binding motif (PsBM) and β- glucan recognition motif (β-GRM) were conserved in the novel sequences of Fein-LGBP. Prediction of motifs, patterns, disulfide bridges and secondary structure were performed for functional characterization of the Fein-LGBP. Three dimensional structure of the Fein-LGBP was generated by Modeller9V8, Swiss Model and validated using NIH server. Results revealed that the modelled structure of Fein-LGBP was 75.7% of residues in allowed region. Theoretical model of Fein- LGBP facilitates to the discovery of new synthetic immune related peptides, agonists that could be useful to  understand the mechanism of LGBP involvement in the prophenoloxidase activating system of crustaceans. The tertiary structure prediction of the immune related gene Fein- LGBP will assist to explore more knowledge in immune system of crustaceans
