Analysis of cryptosystem recognition scheme based on Euclidean distance feature extraction in three machine learning classifiers
Authors: Fan SiJie , Zhao YaQun , Fan SiJie
Published: November 2019

In reality, many cryptographic analysis techniques are based on a specific cryptographic system or a large number of encrypted ciphertext. The identification and detection of cryptographic system is of great significance for evaluating the security of the algorithm and guiding the design and improvement of the algorithm. In this paper, we transcode each character in ciphertext into a decimal number, construct these numbers into one-dimensional arrays, and obtain the Euclidean distance between these one-dimensional arrays. Then we use these distances as features and input them into three machine learning classifiers: random forest, logistic regression and support vector machine to recognize cryptosystem and compare their recognition accuracy. The subjects include 8 common block ciphers (DES, 3DES, AES-128, AES-256, IDEA, SMS4, Blowfish, Camellia-128). The experimental results show that using the feature extraction scheme not only shortens the experimental time, reduces the computational cost, but also improves the recognition accuracy of eight typical block cipher algorithms. The classification accuracy of the ECB mode in the random forest classifier is 75%, which is higher than the existing published literature experimental results. The classification accuracy rate of CBC mode is higher than 13.5%, which is higher than the accuracy of random classification.

Image Denoising Algorithm based on Improved NCSR Model
Authors: Lee XiDa , Wu JunFang
Published: November 2019

The Nonlocally Centralized Sparse Representation (NCSR) algorithm aims to reduce sparse coding noise and utilizes the Nonlocal Self-similarity of the image to improve the effectiveness and accuracy of the image denoising algorithm, which has achieved good denoising effect. However, in the local dictionary learning and sparse coefficient estimation, the algorithm directly uses the Euclidean distance of the noise image to measure the similarity, which will have a certain impact on the final denoising effect. Aiming at this deficiency, it is proposed to use the Gaussian Mixed Model (GMM) to train nonlocal self-similar image patch of the external clean image in the local dictionary learning, and use the learned GMM to guide the internal image clustering; when performing the sparse coefficient estimation, the structural similarity index(SSIM) is introduced into the Euclidean distance and the improved Euclidean distance is introduced into the weight calculation. The experimental results show that the improved algorithm proposed in this paper has improved the PSNR and the visual effect of the image.

Published: November 2019

This study aims to study the response of soybean plants to various scenarios of water supply and compost using the DSSAT model. This research was conducted at the Laboratory of Agro-climatology and Statistics, Department of Agronomy, Faculty of Agriculture, Universitas Hasanuddin, Makassar. This research was conducted in February-March 2016. Simulation of the DSSAT model was determined from primary data in the form of plant management data, soil data, and other supporting data, and secondary data in the form of climate data. The results of the study, based on the paired t-test, the DSSAT model for simulating soybean plants can predict each treatment on the parameters of vegetative weight and number of pods. A t-test on leaf root weight showed that the DSSAT model could predict all treatments except in the treatment of watering every ten days and 3.0 tons/ha of compost. Based on the value of MSE, the DSSAT model for simulating soybean plants can predict the yield of each treatment for the parameters of the number of seeds. The average difference between simulation and observation on seed weight of 314.44 kg/ha and simulation results tend to predict below observation in the field.

Gaga’ chicken is one of the endemic fowls originated from Sidenreng-Rappang Regency in South Sulawesi, Indonesia. This study aimed to describe the morphology and histomorphometry of 1- to 4-month-old Gaga’ chicken’s testes. Eight chicks were used in this study, divided into four groups of ages from 1- to 4-month-old (n = 2). Chicks testes were collected by necropsy, and the histological slides were prepared and stained using the Hematoxilyn-Eosin paraffin method. The results showed there were no significant differences between Gaga’ chicken’s testes and the local breeds. The bodyweight of Gaga’ chicken was in parallel increase with the testes weight, volume, and length (P<0.05). Gonadosomatic Index (GSI) value also showed an increase in spermatozoa production. Spermatocytogenesis phase was observed in 1-month-old, while myogenesis phase in 2-months-old and spermiogenesis in 3- to 4-months-old chicks. The histomorphometry showed that the seminiferous tubules were developed in diameter. The number of seminiferous tubules increased in 1- to 2-months-old chicks but decreased in older chicks as the area became wider. It is suggested that the spermatozoa production increased as the increase of seminiferous tubule area.

Published: November 2019

The land is a very limited resource, so the right to land will cause problems if it is managed improperly. The research is a socio-juridical research and uses a descriptive method. The results show that collective land certification policy in Indonesia is an effort of the government to regulate land tenure and ownership in realizing fairness, benefit and legal certainty. However, its implementation is not undertaken in a planned and gradual manner so that the issuance of title deed in the mass land registration does not consider the formal and material validities of the land certificate. The implementation of state-funded mass land registration as an effort by the state to create fairness, benefit and legal certainty over land tenure and ownership needs to be implemented in a planned and gradual manner. The stage is the first year of research, for measuring in the second year and the issuance of a land titling certificate in the third year. The implementation of gradual and planned land registration will affect the quality of the title deed as issued because the issuance is undertaken by referring to the principle of good land governance.

Market behavior will determine price changes. This study aims to examine the behavior of the organic cashew market with an environmental approach in Southeast Sulawesi. This research was carried out in Southeast Sulawesi Province which was divided into several clusters in Buton Regency, South Buton Regency, Central Buton Regency, Baubau City and Muna Regency, which was conducted in April to July 2019. Determination of the research area was purposive using cluster sampling techniques. The determination of this area is based on the fact that the five regencies/cities are producing organic cashew nuts because they do not fertilize and spray using pesticides. Market behavior was analyzed descriptively qualitatively by observation and interview methods. The number of informants is 437 people from 821 population. Market behavior reviewed includes: (a) Payment system, (b) Determination of prices shows the conditions of price determination at the time of the transaction, (c) Cooperation of marketing institutions. The results of the research show that market behavior is shown in every activity of marketing functions by carrying out activities such as drying, sorting and grading, financing, by establishing cooperation that is built on mutual trust in terms of providing capital, fulfilling the supply of cashews, shipping cashews together, determining prices based on market mechanisms, cost analysis, number of requests and offers by applying a cash, partial, initial and debt payment system. The dominant determinant of prices is traders not farmers although there is a bargain between farmers and traders and prices that occur based on prices that occur in the market and cashew farmers know about market prices available through the farmer’s own network, so that the position of farmers is only as a price recipient (price taker) is not a price maker.

Plantain feathers (Musa Paradisiaca L. var sapientum) is one of the tropical plants that can grow in the highlands with an altitude of 1600 meters above sea level (asl) and in the lowlands. Banana stem as a by-product obtained from banana cultivation (Musa Paradisiaca L. var sapientum) has good potential to be developed as a feed source for energy sources in the supply system of ruminant livestock because the amount of biomass produced is quite large. Based on the results of chemical analysis, banana stems contain fairly good carbohydrate compounds, as seen from the crude fiber content of 21.61% and extract without nitrogen (BETN) of 59.03%. Inadequate water availability is a problem for the growth of banana trees. Drought almost occurs every year, the main limitation of plant growth Efforts to overcome the drought constraints need to be done to get the genotype of banana plants that are resistant to drought stress. This needs to be done as an increase in the growth of bananas as animal feed ingredients. The study was conducted in a completely randomized design with 5 treatments and 5 replications. The treatment is the addition of PEG 6000 into the MS medium (Murashige & Skoog) with a concentration of 0%, 5%, 10%, 15% and 20%. The experimental unit is plantain planted on MS medium. Variance analysis at 5% real level. If the interaction is real, then it will be followed by a BNT test at the 5% real level. The results showed an increase in the stomata index in the leaves of plantain plantlets. The response to the highest increase in the stomata index was seen at a concentration of 20%.

Organic fertilizers are able to bind the ability of soil to absorb water, increase resistance to erosion, improve biodiversity, and increase soil fertility, but will not increase residuals on crop yields so it is safe for the environment and human health. Agricultural waste is a by-product of agriculture that is not utilized or thrown away so that it has no sale value like vegetable waste, rotten fruit, coconut fiber, agricultural waste, fisheries and household waste, which can directly cause environmental pollution, sources disease, and interfering with environmental cleanliness. Rumen cow is a slaughterhouse waste that is not utilized properly, even though the rumen still contains nutrients, microbes and undigested food that can be recycled. The objective of this study was to find out the ratio of the composition of rumen fluid and agricultural waste to the liquid organic fertilizer nutrient content. The analysis method used was 3x3 technique of rumen fluid for each control, namely PI 15% rumen fluid, PII 30% rumen fluid and PIII 45% rumen fluid. The results of the nutrient analysis of organic liquid fertilizer towards agricultural waste and rumen liquid showed that the highest nitrogen in PII is 1.85%, PIII was 1.29% and Pi was 0.68%. The highest phosphorus (P) content in PII was 2.52%, PIII was 2.47% and PI was 1.87% and the highest potassium (K) content was in PII (2.90), PIII was 2.72 and PI was 2.14. According to the results obtained, nutrient analysis of liquid organic fertilizer is in accordance with the quality standards of liquid organic fertilizer regulated in the Agriculture Regulation No. 28/Regulation of the Minister of Agriculture/OT.140/2/200 which stated that liquid organic fertilizer for its N-total content, Phosphorus and Potassium is greater of 2%.

This paper discusses low-power H-bride filters connected to micro-grid networks. Installation of resistors as damping can improve drop power efficiency and maintain THD under the IEEE standard but creates new problems in terms of resonance when increasing output power. Filter analysis and filter results describe the proposed passive LCL H-bridge damping performance. To ensure the desired power out ability and to ensure the desired dynamic performance, the resistor as damping is determined is tested, while the capacitance is chosen to minimize damping reduction. From the results of our research, with the comparative analysis we get, namely: The smaller the resistance value, the smaller the power and efficiency decrease, but the smaller the loss losses, while the greater the value of resistance the higher the output power and efficiency, but frequency losses also higher. The H-bridge filter has excellent capabilities in reducing harmonics 0.6% and power efficiency 92-95%, proving that the 80ohm resistance value is up to 150ohm. At a value of 200ohm, it only produces losses against frequency.
