Abstract:

Security is the level of confidentiality of data stored using cryptography. There are many ways you can do to improve security. In this study, the writer will use a method by encrypting the database with the Caesar Cipher Algorithm, Hill Cipher and Blowfish. Caesar Cipher, Hill Cipher and Blowfish are part of the symmetric algorithm, which means that the encryption and decryption process have the same key. The encryption and decryption process in Caesar Cipher, Hill Cipher and Blowfish Algorithms each has one key. algorithm encryption techniques using symmetric passwords have 2 types, namely block ciphers and stream ciphers. Caesar Cipher, Hill Cipher and Blowfish and Twofish Algorithms are the encryption of the block cipher that breaks or creates blocks to encrypt and obtain cipher text. Result in this paper In Caesar Cipher, it is carried out like 3 blocks of encryption. Whereas in Hill Cipher a word is divided into several blocks and each block is encrypted. In Blowfish, several iterations are performed to get the text cipher, the input is 64 bits of data that can be done as many as 16 iterations. In Twofish the input is 128 bits, in contrast to Blowfish which is only 64 bits, Twofish can also accept 256 bits long and do 16 iterations to get the cipher text. Twofish has stronger security than the 3 algorithms above, Twofish also takes up more memory and takes longer to encrypt.

Abstract:

The spatial forms of hill-neighboring blocks and the wind–thermal environment are crucial components of urban planning and urban ecology. Understanding their correlation is significant for creating a healthy community and enhancing the sustainable level of buildings and their systems. Therefore, Jinan, a multi-mountainous city in China, is taken as the research area, and the ideal model of hill-neighboring blocks is built based on categories of all these block types by aerial imagery and a semantic segmentation algorithm. Then, we use the CFD simulation software PHOENICS and the evaluation system weighted by random forest to simulate and assess the wind–thermal environment. Ultimately, the correlations and specific mathematical equations between the spatial form indicators and wind–thermal environment are obtained by a parametric method. The results demonstrate that the interface density on the near-hill side and hill surface roughness are the most related indicators to the overall wind–thermal environment. The variation in block spatial form has the most distinct influence on the proportion of breeze area and PMV. The relationship determined herein can provide strategic recommendations for decision makers for optimizing the outdoor air flow of blocks and enhancing the thermal comfort of pedestrians, which helps to create a healthy and comfortable outdoor environment in multi-mountainous cities.

Abstract:

Supplementing hill ewes during late pregnancy with hay plus self-help feed-blocks is an established feeding system. However, there is considerable individual and seasonal variation in feed-block intake (Lippert and Milne, 1986) which can limit their effectiveness. This experiment evaluated an alternative system for supplementing hill ewes, during late pregnancy (6 weeks before lambing), based on molassed sugar beet feed (MSBF).One hundred and eighteen single-bearing Swaledale ewes were allocated to one of two treatments; 1. Control - supplemented with hay plus feed-blocks (HB), 2. Supplemented initially with MSBF (nuts), being replaced by a blend (50:50 fresh weight basis) of MSBF and pelleted distillers barley grains (BDG) (MSBF/BDG).The experiment commenced on 18 February 1993. Hay feeding was restricted to 300 g/head/day (HB). High energy (HE) and extra high energy (EHE) feed-blocks, were offered free access (at a rate of one block per 20 ewes). MSBF and MSBF/BDG were fed at a flat rate of 375 g/head/day. HE and MSBF were fed between 18 February and 26 March, being replaced by EHE and MSBF/BDG between 27 March and 10 May. Crude protein (g/kg dry matter (DM)) and metabolisable energy (MJ/kg DM) values were 144 and 9.2; 174 and 9.4; 178 and 10.2; 108 and 12.5; 174 and 12.8 for hay, HE, EHE, MSBF and MSBF/BDG respectively. The ewes were out-wintered on hill grazings.

Abstract:

This paper introduces a novel approach to encrypt color images, utilizing multiple chaotic maps and working with any size pixel blocks. The encryption procedure commences by converting the original image into a vector, which is then divided into equal dimension subblocks. These blocks undergo a new Vigenère transformation, employing two large dynamic substitution tables interconnected by an enhanced Hill operation using a large invertible matrix generated from a pseudo-random table, controlled by another binary dynamics table. Additionally, the truncated block undergoes the same encryption process using another pseudo-random invertible matrix. To evaluate the effectiveness and resilience of our algorithm, we conducted numerous simulations on randomly selected images of varying sizes and formats from diverse databases.

Abstract:

The Pithoragarh district had 2.23 lakh of cattle and 0.86 lakh buffaloes in 2003. Among the cattle there were 92.81% indigenous and most of them (more than 99%) were non- descript and need their characterization. A survey, including 82 farmers and 194 animals of different age and sex was conducted in 8 villages of Munsyari block of Pithoragarh district to characterize the hill cattle. The survey revealed that large number of hill cattle were available in the remote areas like in Munsyari block of the district and in surrounding areas there were large number of crossbred cattle mainly reared for milk production. In the surveyed area cattle were reared for milk, bullock power and manure. Animals were reared mainly on semi-intensive system of management i.e. grazing from morning to afternoon and thereafter stall feeding. In some villages there were no grazing, all the animals were stall fed. Animals were small in size with cylindrical-shaped body. Body colours vary in different colours i.e. brown, black and white or black & white. Tail was long touching to ground with black or white switch. The ranges of different biometric traits showed that animals were closer to Vechur and Punganaur breeds of cattle for their shape and size but smaller than the Hariana and Sahiwal breeds of cattle. The hill cattle available in Pithoragarh area were smaller in size as compared to hill cattle of Almora and bigger to that of cattle of Rudarprayag district. The average birth weight was 9.14 kg The average age at first calving, daily milk yield, lactation length, dry period, service period and calving interval were 40 months, 1.41 kg, 208 days, 138 days, 105 days and 485 days, respectively. Bullocks of the breed were used for 25–40 days in a year for different agricultural operations. A pair of bullock could plough about 6–8 Nali (0.4 acre) of land in a day.

Abstract:

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh during the period from July to October 2016 to study the effect of age of seedling on the yield and yield contributing characters of short duration Aman rice cultivars. The study consisted two factor A: Variety- three- i) BINA dhan7 (V1), (ii) BRRI dhan56 (V2) and (iii) BRRI dhan62 (V3); and factor B: Number of seedlings hill-1- (i) Single seedling hill-1 (S1), (ii) Two seedlings hill-1 (S2) and (iii) Three seedlings hill-1 (S3). The experiment was laid out in a randomized complete block design with three replications. The highest grain yield was obtained from the cultivar BINA dhan7 which was statistically identical with BRRI dhan56 and this was the consequences of higher number of total and effective tillers hiil-1 and highest number of grains panicle-1. Grain yield was not significantly affected by the number of seedlings hill-1 but numerically the highest grain yield was recorded from single seedling hill-1. From the interaction it is observed that grain yield was not significantly affected by the interaction of cultivar and number of seedlings hill-1. But numerically the highest grain yield was recorded from the interaction of BRRI dhan56 × single seedling hill-1. From the economic analysis it is observed that the highest BCR (1.64) was recorded from single seedling hill-1 in BRRI dhan56 which was close to single seedling hill-1 in BINA dhan7 and the lowest BCR (103) was obtained from two seedlings hill-1 in BRRI dhan62. From the results of the study it may be concluded that BRRI dhan56 with single seedling hill-1 might be cultivated in AEZ-9 for obtaining higher yield and higher economic return in Aman season.Progressive Agriculture 28 (4): 279-286, 2017

Abstract:

The urban heat island (UHI) effect is caused by intensive development practices in cities and the diminished presence of green space that results. The evolution of these phenomena has occurred over many decades. In many cities, historic zoning and redlining practices barred Black and minority groups from moving into predominately white areas and obtaining financial resources, a practice that still affects cities today, and has forced these already disadvantaged groups to live in some of the hottest areas. In this study, we used a new dataset on the spatial distribution of temperature during a heat wave in Richmond, Virginia to investigate potential associations between extreme heat and current and historical demographic, socioeconomic, and land use factors. We assessed these data at the census block level to determine if blocks with large differences in temperature also had significant variation in these covariates. The amount of canopy cover, percent impervious surface, and poverty level were all shown to be strong correlates of UHI when analyzed in conjunction with afternoon temperatures. We also found strong associations of historical policies and planning decisions with temperature using data from the University of Richmond’s Digital Scholarship Lab’s “Mapping Inequality” project. Finally, the Church Hill area of the city provided an interesting case study due to recent data suggesting the area’s gentrification. Differences in demographics, socioeconomic factors, and UHI were observed between north and (more gentrified) south Church Hill. Both in Church Hill and in Richmond overall, our research found that areas occupied by people of low socioeconomic status or minority groups disproportionately experienced extreme heat and corresponding impacts on health and quality of life.

Abstract:

The assignment of diploma thesis was the design of a sustainable urban structure based on a medieval city in Náměšť nad Oslavou. As part of the work, I tried to find the best solution for this solved area, which is isolated by a railway corridor and suggest a new city district based on the principle of a medieval city, which will be linked to the existing city. The proposed development of city blocks is built on a system of platforms that level the terrain within the blocks and enable optimal parking spaces and the use of commercials. This development is complemented by several blocks with villa houses and a city SPA complex. The proposal supports the construction of cycle paths that connect parts of the solved area with the Rathan recreation pond. The design also includes a large park with a lookout tower and a sports ground on the city horizon ner the SPA complex. The accent was also placed on the public area near the new railway station, which serves to gather people for cultural and entertainment opportunities. This public space should not compete with an existing Masaryk square, which fulfills a representative and administration function.

Abstract:

The diploma thesis deals with an urban study on the territory of Červený kopec, specifically in the part of the territory of Stráň. It is a locality stated as a brownfield Kohnova cihelna. The proposal aims to make the most of the potential of this site, which lies in its proximity to the city center, the neighborhood of the national natural monument, a significant area of greenery and the views that this place provides due to its topographic situation. A new city district is proposed on the area of 18 hectares, which would cover one of the "brownfield holes" on the map of the city of Brno and at the same time help against the outflow of population to the outskirts of the city and against the creation of urban satellites. Numerous public opinion polls show that they would like to live close to the city, but at the same time especially young families long for their own house in a quiet countryside location. Therefore, a compact development of terraced houses, terrace villas and blocks of flats with private courtyards is proposed here, complemented by quality public space and civic amenities. This new city district would offer housing for about 3,500 new residents.

Abstract:

The diploma thesis follows up the area in the center of Náchod along the former textile factory Tepna, which is located at the transition between the historical center and the housing estate. The proposal is based on problem analysis and uses the potential, limits and quailities of the area. The concept is a new urban quarter with a residential block of buildings complemented by civic amenities and high-quality public spaces. The design preserves the existing building of the Bílá Tepna, for which a new functional use is proposed. The proposal is solved with respect to the character of the place, the connection to the surrounding buildings and the emphasis on the preference of pedestrian traffic over the automobile traffic.

Abstract:

The thesis deals with the design of the area after the former brownfield of Tepna Náchod. The aim of the thesis is activate the territory, to revive the city center and to design the buildings in connection with the historical center and the chateau with a suitable functional structure, responding to the city's shortcomings. The proposal respects the character of the place trying to prefer pedestrian and cycling – pedestrian zones, cycling zones. The concept is based on the maximum use of built-up areas in the designed area and on the permeability of the entire area, the interconnection of three squares and the creation of a new public space. Furthermore, the concept responds to the historical city center and the chateau hill - views, perspective axes. Newly designed buildings are residential buildings with active parterres, administrative building for research and development, multi-purpose hall, retirement home, kindergarten, federal house and parking house. The new development clearly defines the street network. Part of the design is the planting of a park under the chateau hill with the revival of the trough of the Plhovsky´s stream.

Abstract:

AbstractOptimization problems are frequent in several fields, such as the different branches of Engineering. In some cases, the objective function exposes mathematically exploitable properties to find exact solutions. However, when it is not the case, heuristics are appreciated. This situation occurs when the objective function involves numerical simulations and sophisticated models of reality. Then, population-based meta-heuristics, such as genetic algorithms, are widely used because of being independent of the objective function. Unfortunately, they have multiple parameters and generally require numerous function evaluations to find competitive solutions stably. An attractive alternative is DIRECT, which handles the objective function as a black box like the previous meta-heuristics but is almost parameter-free and deterministic. Unfortunately, its rectangle division behavior is rigid, and it may require many function evaluations for degenerate cases. This work presents an optimizer that combines the lack of parameters and stochasticity for high exploration capabilities. This method, called Tangram, defines a self-adapted set of division rules for the search space yet relies on a stochastic hill-climber to perform local searches. This optimizer is expected to be effective for low-dimensional problems (less than 20 variables) and few function evaluations. According to the results achieved, Tangram outperforms Teaching-Learning-Based Optimization (TLBO), a widespread population-based method, and a plain multi-start configuration of the stochastic hill-climber used.

Abstract:

In classical cryptography, the Hill cipher, invented by Lester Hill in 1929, was the first polygraphic substitution cipher based on linear algebra, which practically processed more than three symbols at once. In the classical Hill cipher, each letter is represented by a number modulo 26. To encrypt a message, each block of n letters (considered as an n-component vector) is multiplied by an invertible matrix of size n×n, again modulus 26. In order to decrypt the message, each block is multiplied by the inverse matrix of the matrix used for encryption. In the paper a modified algorithm for encryption and decryption using the Hill cipher on the basis of 2×2-matrix and 64-symbol alphabet is proposed. Here each symbol (Latin letters, decimal digits and punctuation signs) is represented by a number modulo 64 and all arithmetic operations are done by modulo 64 (the number of letters in the alphabet instead of modulo 26). The paper describes MS EXCEL-based application implementing the processes of encryption and decryption of English texts using the Hill cipher based on the matrix of size 2×2 and 64-symbol alphabet. The processes of encryption and decryption of 6-character words in English are illustrated. Numerous examples obtained by the application developed are presented in the paper. The material is used in the educational process in the course “Telecommunication Security” by students of the specialty “Telecommunication Systems” for the Bachelor degree at the University of Ruse but it can be applied in other disciplines involving issues of cryptographic information protection.

Abstract:

Abstract An oil-bearing structure in the southwest of Bozhong Sag in Bohai Oilfield contains large oil and gas reserves. It will be a key area for Bohai oilfield to increase reserves production. The main target layer in this block is the fractured granite formation in buried hill. Exploration work in this block is faced with many operational problems such as "deep burial, high temperature and high pressure (HTHP), low penetration rate, difficult reservoir protection, and low accuracy interface determination". Through technical research and field practice, aiming at "all well sections drilling rate speed-up, operation safely and efficiently, and releasing production capacity", a set of key technology system suitable for offshore oilfield deep exploration is formed. Since the application of this technology system, it has effectively improved the efficiency of well construction, greatly reduced the cost of exploration and operation, facilitated the discovery of oil and gas in multiple mid-depth strata. It has achieved a good operation effect on social and economic benefit.

Abstract:

The High Fidelity Building Block and Validation Protocols for NextGen Composite Methods Program (N00014-21-C-1008) seeks to provide industry with the critical experimental data and supporting guidelines by which to evaluate, validate, and demonstrate the predictive capabilities of advanced computational analysis tools. Following from the successful development of a coupon level database (N00014-14-C-0128), the HiFi NextGen program focuses on the subelement and element levels of the design-test-certification building block wherein the greatest expense for design substantiation is incurred. Additionally, data is developed to provide improved understanding of fundamental material behavior for composite material models. Advanced inspection techniques such as digital image correlation and in-situ micro computed tomography are used to capture damage onset, damage propagation, and ultimate failure within representative composite structure test specimens. Where applicable, the test program includes relevant environmental conditions. Validation guidelines focus on the use of emerging progressive damage and failure analysis (PDFA) computational techniques and address modeling considerations such as length scale, material models, numeric implementation, mesh objectivity, modeling strategy, and computational scalability. All test articles are fabricated from IM7/5320-1 tape and fabric as well as FM309-1 structural adhesive to maintain a high degree of relevancy for future aircraft needs.

Abstract:

ABSTRACT The wellbore instability is a vital problem when drilling in the ultra-deep carboniferous shale formation in the southwest block of Tarim Oilfield. And, bits are frequently blocked and stuck. Unfortunately, the problems are hardly to be effectively solved by increasing the drilling fluid density. At present, the mechanism of wellbore collapse in the block is still unclear. In this way, it is unable to establish an effective prediction model for wellbore collapse. Therefore, this paper systematically analyses the formation mineral characteristics, physical and chemical properties and stress state in the block to clarify the reasons for wellbore instability of mud shale formation. Consequently, the wellbore stability model of mud shale is established considering the degree of formation collapse, drilling fluid density, activity and plugging. Then, through quantitative analysis and definition of the relationship between the wellbore collapse degree and the density and performance of drilling fluid, the technical countermeasures for wellbore stability are proposed. The analysis model proposed in this paper provides a new way for quantitative design of drilling fluid density and performance in ultra-deep carboniferous mud shale formations. INTRODUCTION Based on statistics, the confirmed recoverable reserves of deep oil and gas reach up to 7.29×1010 t oil equivalent, constituting 49.07% of the world's total recoverable reserves. As much as 70% of China's unconventional oil and gas resources are stored in deep formations, leading to a growing number of ultra-deep wells drilled(Chen et al., 2009; Y. Lu et al., 2011; Zhang et al., 2022). The Tarim Basin in China is a significant region for its vast oil and gas reserves. The Tangu Depression, particularly the Madong buried hill belt in the southwest block of the Tarim Basin, is recognised for its abundant oil and gas resources. However, the Madong structural belt underwent multiple tectonic movements, resulting in extremely complex structural conditions in the basin. The reservoirs in this area are buried deep, reaching depths of more than 6000m on average and are subjected to high temperatures and ultra-high pressure. As a result, this area faces complex wellbore stability issues during exploration and development. In the initial stages of development, due to an unclear understanding of the lithological characteristics and structural stress in the area, complex problems such as well wall collapse, drag, and pipe sticking were common during the drilling process(Zhang & Chen, 2022).

Abstract:

A hardware-in-the-loop-simulation (HiLS) procedure for a direct-fired fuel cell turbine hybrid power system was evaluated for an integrated gasifier/fuel cell/turbine hybrid cycle (IGFC), implemented through the Hybrid Performance (Hyper) project at the National Energy Technology Laboratory, U.S. Department of Energy (NETL). The Hyper facility is designed to explore dynamic operation of hybrid systems and quantitatively characterize such transient behaviour. It is possible to model, test and evaluate the effects of different parameters on the design and operation of a gasifier/fuel cell/gas turbine hybrid system and quantify risk mitigation strategies. The previous implementation of emergency shut-down control strategies resulted in turbomachinery hardware failure. The primary linking event in these cases was compressor stall and surge resulting from the sudden loss of fuel during implementation of the standard double block and bleed strategy used during emergency failure. A new mitigation strategy involving automated ramps is proposed and described in detail to control the system from start-up to forced emergency shut-down. The control architecture shows how the virtual fuel cell model can be coupled to the real gas turbine safely, in all of stage of operations. The paper includes improvements to the emergency shutdown procedure, failure analyses, and the comparison of experimental data with previous results.

Full text

Abstract:

In a recent investigation, Hill et al. show that the wavelengths of sharp structural resonances in the fluorescence emission from single dielectric microspheres resting on glass and metallic substrates are the same as those for unsupported microspheres.1 The objective in the present study was to obtain resonance light-scattering (RLS) spectra from an ensemble of nonfluorescing dielectric microspheres. The incident light from a dye laser was swept continuously through a range of wavelengths, and the intensity of the elastically scattered light at 90° was recorded as a function of wavelength. The resultant RLS spectrum was then compared to Mie-scattering computer calculations for unsupported microspheres, averaged over a diameter distribution. Three different types of substrate were used: ultrablack-coated metal; black glass; and clear glass. For polystyrene microspheres on the ultrablack-coated metal substrate, the experimental RLS spectra were in good agreement with Mie-scattering calculations for unsupported dielectric microspheres. This was true regardless of the tilt angle of the substrate relative to the incident and scattered light fields as long as the scattering angle was not changed. However, for microspheres on the black- and clear-glass substrates, the match with Mie calculations was not so good; in particular, the RLS patterns changed appreciably as the substrates were tilted. This is most likely due to the light reflected from the glass substrates which was not present with the highly absorbing ultrablack-coated metal substrate.

Abstract:

In this work multispectral reflectance images are used in conjunction with a neural network classifier for the purpose of detecting and classifying weeds under real field conditions. Multispectral reflectance images which contained different combinations of weeds and crops were taken under actual field conditions. This multispectral reflectance information was used to develop algorithms that could segment the plants from the background as well as classify them into weeds or crops. In order to segment the plants from the background the multispectrial reflectance of plants and background were studied and a relationship was derived. It was found that using a ratio of two wavelenght reflectance images (750nm and 670nm) it was possible to segment the plants from the background. Once ths was accomplished it was then possible to classify the segmented images into weed or crop by use of the neural network. The neural network developed for this work is a modification of the standard learning vector quantization algorithm. This neural network was modified by replacing the time-varying adaptation gain with a constant adaptation gain and a binary reinforcement function. This improved accuracy and training time as well as introducing several new properties such as hill climbing and momentum addition. The network was trained and tested with different wavelength combinations in order to find the best results. Finally, the results of the classifier were evaluated using a pixel based method and a block based method. In the pixel based method every single pixel is evaluated to test whether it was classified correctly or not and the best weed classification results were 81% and its associated crop classification accuracy is 57%. In the block based classification method, the image was divided into blocks and each block was evaluated to determine whether they contained weeds or not. Different block sizes and thesholds were tested. The best results for this method were 97% for a block size of 8 inches and a pixel threshold of 60. A simulation model was developed to 1) quantify the effectiveness of a site-specific sprayer, 2) evaluate influence of diffeent design parameters on efficiency of the site-specific sprayer. In each iteration of this model, infected areas (weed patches) in the field were randomly generated and the amount of required herbicides for spraying these areas were calculated. The effectiveness of the sprayer was estimated for different stain sizes, nozzle types (conic and flat), nozzle sizes and stain detection levels of the identification system. Simulation results indicated that the flat nozzle is much more effective as compared to the conic nozzle and its relative efficiency is greater for small nozzle sizes. By using a site-specific sprayer, the average ratio between the spraying areas and the stain areas is about 1.1 to 1.8 which can save up to 92% of herbicides, especially when the proportion of the stain areas is small.
